DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings in general and to FIG. 1 in particular, shown therein and designated via the general reference numeral 10 is a survival stick constructed in accordance with the present invention. The survival stick 10 includes an upper section 12, a lower section 14 and a plurality of intermediate sections 16, only two intermediate sections being shown in the drawings and designated therein via the reference numerals 16a and 16b since the intermediate sections 16 are identical in construction. The sections 12, 14 and 16 are interconnected to form the survival stick 10. The sections 12, 14 and 16 are connectable to form a walking stick (as shown in FIG. 1) which can be utilized by an individual in various hiking or camping type activities. In addition, the sections 12, 14 and 16 each include a compartment for storing various items such as medical supplies or blankets, for example, which may be useful to an individual in various emergency situations. Also, the upper section 12 of the survival stick 10 is connectable to the uppermost intermediate sections 16a (as shown in FIG. 2) to form a crutch-like structure for supporting an individual should an individual's leg become injured during such hiking or camping type activities.
The upper section 12 is constructed of a tubular material, such as aluminum tubing, for example. The upper section 12 has an upper end 18 and a lower end 20 and an opening 22 which extends through the upper section 12 intersecting the upper and lower ends 18 and 20. A portion 24 of the upper section 12 generally near the upper end 18 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 24 generally near the upper end 18 is threaded. A portion 26 of the upper section 12 generally near the lower end 20 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 26 generally near the lower end 20 is threaded. The opening 22 extending through the upper section 12 is constructed to cooperate in forming a compartment 27 in the upper section 12 for storing items. It should be noted that, in one form, the opening 22 could intersect only the lower end 20 and extend a distance through the upper section 12 generally toward the upper end 18 thereby closing the upper end portion of the opening 22, for reasons which will be made more apparent below.
The lower section 14 is constructed of a tubular material, such as aluminum tubing, for example. The lower section 14 includes an upper end 28, a lower end 30 and an opening 32. The opening 32 extends through the lower section 14 intersecting the upper and the lower ends 28 and 30. The opening 32 is constructed to cooperate in forming a compartment 33 in the lower section 14. A portion 34 of the lower section 14 generally near the upper end 28 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 34 generally near the upper end 28 is threaded. A portion 36 of the lower section 14 generally near the lower end 30 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 36 generally near the lower end 30 is threaded. It should be noted that, in one form, the opening 32 could intersect only the upper end 28 and extend a distance through the lower section 14 generally toward the lower end 30 thereby closing the lower end portion of the opening 32, for reasons which will be made more apparent below.
The intermediate sections 16a and 16b are each constructed in a similar manner and each intermediate section 16a and 16b includes an upper end 38, a lower end 40 and an opening 42 extending therethrough intersecting the upper and lower ends 38 and 40 thereof (the various portions of the intermediate sections 16a and 16b also being designated via the letters "a" and "b" respectively for identification). The opening 42 is constructed and disposed to cooperate in forming a compartment chamber 43 in the intermediate section 16 for storing items. In one form, the opening 42 could intersect only one of the upper and lower ends 28 and 40 and extend a distance through the intermediate section 16 thereby providing a closed end on each intermediate section 16a and 16b.
A portion 44 of each intermediate section 16a and 16b generally near the upper end 38 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 44 is threaded. A portion 46 of each intermediate section 16a and 16b generally near the lower end 40 is tapered inwardly and a portion of the outer peripheral surface of the tapered portion 46 is threaded.
The survival stick 10 includes a plurality of collars 48 or, more particularly, three collars 48a, 48b and 48c in the embodiment of the invention shown in FIGS. 1 and 2. The collars 48 are identical in construction and each collar 48 includes opposite ends 50 and 52. A first opening 54 intersects the end 50 of each collar 48 and the first opening 54 extends a distance through the collar 48 generally toward the opposite end 52. A second opening 56 intersects the end 52 of each collar 48 and the second opening 56 extends a distance through the collar 48 generally toward the opposite end 50. The openings 54 and 56 do not intersect and thus a portion 58 of each collar 48 extends across each opening 54 and 56, each portion 58 extending transversely across a central portion of one of the collars 48.
The inner peripheral surface of each collar 48 formed by the first opening 50 is threaded and the inner peripheral surface of each collar formed by the second opening 52 is threaded. The collars 48 are constructed to cooperate in connecting the sections 12, 14 and 16 to form the survival stick 10 of the present invention.
As shown in FIG. 1, the threaded, tapered portion 26 of the upper section 12 is threadedly inserted into the first opening 50 of the collar 48a and the threaded, tapered portion 44a of the intermediate section 16a is threadedly inserted into the second opening 52 of the same collar 48a. Thus, the collar 48a cooperates to threadedly and removably connect the lower end 20 of the upper section 12 to the upper end 38a of the intermediate section 16a. In the connected position of the upper section 12 and the intermediate section 16a, the portion 58 of the collar 48a extends between and, in essence, closes the lower end 20 of the upper section 12 and the upper end 38a of the intermediate section 16a. Thus, the collar 48a and, more particularly, the portion 58 of the collar 48a cooperates to retain items within the compartment 27 by closing the lower end 20 of the upper section 12. Further, the portion 58 of the collar 48a cooperates to retain items within the compartment 43a of the intermediate section 16a by closing the upper end 38a of the intermediate section 16a.
The threaded, tapered portion 46a of the intermediate section 16a is threadedly inserted into the first opening 50 of the collar 48b and the threaded, tapered portion 44b of the intermediate section 16b is threadedly inserted into the second opening 52 of the same collar 48b. Thus, the collar 48b cooperates to threadedly and removably connect the lower end 40a of the intermediate section 16a to the upper end 38b. In the connected position of the intermediate sections 16a and 16b, the portion 58 of the collar 48b extends between and, in essence, closes the lower end 40a of the intermediate section 16a and the upper end 38b of the intermediate section 16b. The portion 58 of the collar 48b cooperates to retain items within the compartment 43a by closing the lower end 40a of the intermediate section 16a. The portion 58 of the collar 48b also cooperates to retain items within the compartment 43b by closing the upper end 38b of the intermediate section 16b.
The threaded, tapered portion 34 of the lower section 14 is threadedly inserted into the second opening 52 of the collar 48c and the threaded, tapered portion 46b of the intermediate section 16b is threadedly inserted into the first opening 50 of the collar 48c. The collar 48c cooperates to connect the lower end 40b of the intermediate section 16b to the upper end 28 of the lower section 14. In the connected position of the intermediate section 16b and the lower section 14, the portion 58 of the collar 48c extends between and, in essence, closes the lower end 40b of the intermediate section 16b and the upper end 28 of the lower section 14. The portion 58 of the collar 48c cooperates to retain items within the compartment 43b by closing the lower end 40b of the intermediate section 16b, and the portion 58 of the collar 48c cooperates to retain items within the compartment 33 by closing the upper end 28 of the lower section 14.
The survival stick 10 also includes two caps 60a and 60b. The caps 60a and 60b are identical in construction and each cap 60a and 60b includes a closed end 62 and an opposite, open end 64. An opening 66 is formed through the end 64 of each cap 60a and 60b, the opening 66 extending a distance through the caps and operating to form the open end 64. A portion of the inner peripheral surface formed in each cap 60a and 60b by the openings 66 is threaded.
The tapered portion 24 of the upper section 12 is threadedly inserted into the opening 66 in the caps 60a and the cap 60a thus is threadedly secured to the upper end 18 of the upper section 12. The cap 60a cooperates to retain items within the compartment 27 by closing the upper end 18 of the upper section 12.
The tapered portion 46b of the intermediate section 16b is threadedly inserted into the opening 66 in the cap 60b and the cap 60b thus is threadedly secured to the lower end 30 of the lower section 14. The cap 60b cooperates to retain items within the compartment 33 by closing the lower end 30 of the lower section 14.
An opening 68 is formed through a central portion of the upper section 12 generally midway between the upper and the lower ends 18 and 20. The opening 68 extends generally transversely with respect to the opening 22 and the opening 68 intersects the opening 22. The peripheral surface formed in the upper section 12 by the opening 68 is threaded.
In operation, the caps 60a can be threadedly connected to the upper section 12 and, in this position, items then can be loaded into the compartment 27, the items being retained within the compartment 27 by the cap 60a which closes the upper end 12 of the upper section 12. The upper end 38a of the intermediate section 16a can be threadedly connected to the collar 48a and then items can be loaded into the compartment 43a, the items being retained within the compartment 43a by the collar 48a which closes the upper end 38a of the intermediate section 16a. The upper end 38b of the intermediate section 16b can be threadedly connected to the collar 48b and then items can be loaded into the compartment 43b, the items being retained within the compartment 43b by the collar 48b which closes the upper end 38b of the intermediate section 16b. The cap 60b can be threadedly connected to the lower end 30 of the lower section 14 and then items can be loaded into the compartment 33 of the lower section 14, the items being retained within the compartment 33 by the caps 60b which closes the lower end 30 of the lower section 14.
After the compartments 27, 43a, 43b and 33 have been loaded with the appropriate items, the upper section 12 is removably connected to the intermediate section 16a via the collar 48a, the intermediate section 16a is removably connected to the intermediate section 16b via the collar 48b and the intermediate section 16b is removably connected to the lower section 14 via the collar 48c. In this position, the sections 12, 16a, 16b and 14 are interconnected to form a walking stick which can be utilized by an individual to assist in walking during hiking or camping or the like activities. During such activities if access to any of the compartments 27, 43a, 43b or 33 is desired for any reason, such access is readily attainable by removing either one of the caps 60a or 60b or one of the collars 48a, 48b or 48c. More particularly, if access is desired into one of the compartments 43a or 43b of the intermediate sections 16a or 16b, respectively, such intermediate section 16a or 16b can be unthreaded from the collar 48a, 48b or 48c to provide such access.
During activities such as hiking or camping or the like, it is not unusual for one to injure a leg such as via a sprain or broken bone. In such event, it can be critical that the individual have ready access to something to assist the individual's walking function. In the event of such an unfortunate occurrance, the individual simply unthreads the upper section 12 from the collar 48a and then removes the collar 48a from the intermediate section 16a, thereby exposing the tapered, threaded portion 44a of the intermediate section 16a. The threaded portion 44a then is threaded into the opening 68 in the upper section 12 thereby connecting the upper section 12 to the intermediate section 16a to form a crutch-like structure wherein the upper section 12 extends generally perpendicularly with respect to the intermediate sections 16a and 16b and the interconnected lower section 14, as shown in FIG. 2. In this position as shown in FIG. 2, the individual can use the survival stick 10 as a crutch to assist the individual in walking. In addition to the walking assistance, the individual may be using the survival stick 10 to walk to various remote locations and some mishap may occur wherein the individual requires some medication or a blanket or some other medical item. Utilizing the survival stick 10 of the present invention, the individual has ready access to such items, since such items are stored within the compartments 27, 43a, 43b and 33. Thus, the survival stick 10 of the present invention not only provides a practical walking stick, but the survival stick 10 can be employed to assist in various mishaps and, in some instances, the survival stick 10 may be useful in avoiding a disastrous conclusion.
Embodiment of FIG. 3
Shown in FIG. 3 and designated via the reference numeral 10d is a modified survival stick similar to the survival stick 10 shown in FIGS. 1 and 2.
The upper section 12d is constructed exactly like the upper section 12, as shown in FIG. 1, except the opening 22d does not extend through the entire length of the upper section 12d. Rather, the opening 22d intersects the upper end 18d and extends a distance through the upper section 12d. Thus, the lower end 20d is closed and the upper end 18d is open.
The intermediate sections 16e and 16f are constructed exactly like the intermediate sections 16a and 16b, shown in FIG. 1, except the openings 42e and 42f do not extend through the entire length of the intermediate sections 16a and 16b, respectively. Rather, the openings 42e and 42f each intersect the upper ends 38e and 38f, respectively, and each opening 42e and 42f extends a distance through the intermediate section 16e and 16f, respectively, thereby providing a closed, lower end 40e and 40f and an open, upper end 39e and 38f in the intermediate sections 16e and 16f.
The lower section 14d is constructed exactly like the lower section 14, as shown in FIG. 1, except the opening 32d does not extend through the entire length of the lower section 14d. Rather, the opening 32d intersects the upper end 28d and extends a distance through the lower section 14d, thereby providing an open, upper end 28d and a closed, lower end 30d.
The cap 60a is threadedly connected to the tapered portion 24d of the upper section 12d, in a manner and for reasons exactly like that described before with respect to the upper section 12 and the cap 60a. The cap 60b is threadedly connected to the tapered portion 34d of the lower section 14d, in a manner and for reasons exactly like that described before with respect to the lower section 14 and the cap 60b.
The survival stick 10d includes three collars 70 (designated in the drawing as 70d, 70e and 70f, respectively). The collars 70d, 70e and 70f are identical in construction and the collars 70d, 70e and 70f are constructed similar to the collars 48a, 48b and 48c, shown in FIG. 1. The collars 70 each include opposite ends 72 and 74 and an opening 76 extends therethrough intersecting the opposite ends 72 and 74. The collars 70 cooperate to connect the upper section 12 to the intermediate section 16e, to connect the intermediate section 16a to the intermediate section 16f and to connect the intermediate section 16f to the lower section 14d in a manner exactly like that described before with respect to the collars 48 shown in FIG. 1, except the collars 70 do not include a portion extending transversely across the opening through the collar similar to the portion 58 of the collars 48, since the opening 76 extends completely through each of the collars 70 intersecting the opposite ends 72 and 74. This construction of the collar 70 is possible since one end of each of the sections 12d, 16e, 16f and 14d is closed because the opening in these sections does not extend completely through the section.
Embodiment of FIG. 4
Shown in FIG. 4 is another modified survival stick 10g which is constructed similar to the survival sticks 10 and 10d described in detail before.
The survival stick 10g includes a modified upper section 12g which is constructed exactly like the upper section 12 shown in FIG. 1, except the opening 22g does not extend completely through the upper section 12g. The opening 22g intersects the lower end 20g and extends a distance through the upper section 20g generally toward the upper end 18g thereby forming a closed upper end 18g since the opening 22g does not extend through the upper end 18g.
A portion of the upper section 12g generally near the upper end 18g is tapered to form a tapered portion 24g and the outer peripheral surface of the tapered portion 24g is threaded. A tapered portion is not formed near the lower end 20g in a manner like the tapered portion 24 of the upper section 12 shown in FIG. 1. However, a portion of the inner peripheral surface formed in the upper section 12g by the opening 22g and generally near the lower end 20g is threaded, as shown in FIG. 4.
The lower section 14g is constructed exactly like the lower section 14 shown in FIG. 1, except the opening 32g does not extend completely through the lower section 14g and both ends of the lower section 14g are not tapered. The opening 32g intersects the lower end 30g of the lower section 14g and extends a distance through the lower section 14g generally toward the upper end 28g thereby forming a closed upper end 28g because the opening 32g does not extend completely through the lower section 14g. A threaded, tapered portion 34g is formed on the lower section 14g generally near the upper end 28g thereof in a manner like that described before with respect to the tapered portion 34 of the lower section 14 shown in FIG. 1.
A tapered portion is not formed on the lower section 14g generally near the lower end 32g in a manner like that described before with respect to the tapered portion 36 of the lower section 14 shown in FIG. 1. Rather, a portion of the inner peripheral surface formed in the lower section 14g by the opening 32g and generally near the lower end 30g is threaded, as shown in FIG. 4.
The intermediate section 16h is constructed similar to the intermediate section 16 shown in FIG. 1, except the opening 42h does not extend completely through the intermediate section 16h and both ends of the intermediate section 16h are not tapered. The opening 42h intersects the end 40h and extends a distance through the intermediate section 16h generally toward the upper end 38h thereby forming a closed upper end 38h. A tapered portion 44h is formed on the intermediate section 16h generally near the upper end 38h and a portion of the outer peripheral surface of the tapered portion 44h is threaded in a manner like that described before with respect to the tapered portion 44 of the intermediate section 16h shown in FIG. 1. A tapered portion is not formed on the intermediate section 16h generally near the lower end 40h like that described before with respect to the tapered portion 46 on the intermediate section 16 shown in FIG. 1. A portion of the inner peripheral surface formed in the intermediate section 16h by the opening 42h and generally near the lower end 40h is threaded, as shown in FIG. 4.
The intermediate section 16i is constructed exactly like the intermediate section 16 shown in FIG. 1, except the opening 42i does not extend completely through the intermediate section 16i and both ends of the intermediate section 16i are not tapered. The opening 42i intersects the lower end 40i and extends a distance through the intermediate section 16i generally toward the upper end 38i thereby forming a closed upper end 38i. A tapered portion 44i is formed on the intermediate section 16i generally near the upper end 38i and a portion of the outer peripheral surface formed by the tapered portion 44i is threaded in a manner like that described before with respect to the tapered portion 44 of the intermediate section 16 shown in FIG. 1. A tapered portion is not formed on the intermediate section 16i generally near the lower end 40i like the tapered portion 46 on the intermediate section 16i shown in FIG. 1. A portion of the inner peripheral surface formed in the intermediate section 16i by the opening 42i and generally near the lower end 40i is threaded as shown in FIG. 4.
To assemble the survival stick 10g, the cap 60a is threadedly connected to the tapered portion 24g of the upper section 12g in a manner and for reasons like that described before with respect to the cap 60a and the upper section 12 shown in FIG. 1. The tapered portion 44h of the intermediate section 16h then is threadedly inserted through the lower end 20g and into the opening 22g of the upper section 12g thereby threadedly connecting the upper section 12g to the intermediate section 16h. The tapered portion 44i of the intermediate section 16i is threadedly inserted through the lower end 40h and into the opening 42h of the intermediate section 16h to threadedly connect the intermediate sections 16h and 16i. The tapered portion 34g of the lower section 14g is threadedly inserted through the lower end 40i and into the opening 42i of the intermediate section 16i to threadedly connect the lower section 14g to the intermediate section 16i.
The survival stick 10g also includes a cap 80 having opposite ends 82 and 84. A reduced diameter portion 86 is formed on the cap 80 extending from the end 82 generally toward the end 84 thereof. A portion of the outer peripheral surface of the reduced diameter portion 86 is threaded, as shown in FIG. 4. To complete the assembly of the survival stick 10g, the reduced diameter portion 86 of the cap 80 is threadedly inserted through the lower end 30g and into the opening 32g of the lower section 14g to close the lower end 30g and complete the assembly of the survival stick 10g.
The survival stick 10g will operate in a manner like that described before with respect to the survival stick 10 (shown in FIG. 1) and 10d (shown in FIG. 3) except the modified construction of the sections 12g, 14g, 16h and 16i are such that there is no need for collars similar to the collars 40 and 70 shown in FIGS. 1 and 3.
Embodiment of FIG. 5
The survival stick 10k shown in FIG. 5 is constructed exactly like the survival stick 10d shown in FIG. 3, except: the opening 22k extends completely through the upper section 12k intersecting the upper and the lower ends 18k and 20k; the opening 42m extends completely through the intermediate section 16m intersecting the upper and the lower ends 38m and 40m; the opening 42n extends completely through the intermediate section 16n intersecting the upper and the lower ends 38n and 40n; and the opening 32k extends completely through the lower section 14k intersecting the upper and the lower ends 28k and 30k. Also, the modified survival stick 10k shown in FIG. 5 includes a first, a second, a third and a fourth insert, 90, 92, 94 and 96.
The inserts 90, 92, 94 and 96 are identical in construction. The insert 90 is disposed in the opening 22k in the upper section 12k and secured to the upper section 12k generally near the lower end 20k thereby closing the lower end 20k of the upper section 12k. The insert 92 is disposed in the opening 42m of the intermediate section 16m and the insert 92 is secured to the intermediate section 16m generally near the lower end 40m thereby closing the lower end 40m of the intermediate section 16m. The insert 94 is disposed in the opening 42n of the intermediate section 16n and the insert 94 is secured to the intermediate section 16n generally near the lower end 40n thereof thereby closing the lower end 40n of the intermediate section 16n. The insert 96 is disposed in the opening 32k in the lower section 14k and the insert 96 is secured to the lower section 14 k generally near the lower end 30k thereof, thereby closing the lower end 30k of the lower section 14k.
The survival stick 10k will operate and is assembled in a manner exactly like that described before with respect to the survival stick 10d, except the inserts 90, 92, 94 and 96 constitute a separate element which must be secured to the respective sections 12k, 16m, 16n and 14k.
Embodiment of FIG. 6
Shown in FIG. 6 is another modified survival stick 10p which is constructed similar to the survival stick 10 shown in FIG. 1 and described in detail before, except the survival stick 10p includes a modified upper section 12p, a modified intermediate section 16p, a modified intermediate section 16r, a modified lower section 14p and a pair of caps 100 and 102. In addition, the survival stick 10p includes three connectors 98 which are identical in construction, the connectors being designated in FIG. 6 via the reference numerals 98p, 98r and 98s.
The upper section 12p is constructed exactly like the upper section 12 shown in FIG. 1, except the upper section 12p does not include tapered portions similar to the tapered portions 24 and 26 (shown in FIG. 1) and a portion of the inner peripheral surface formed by the opening 22p and generally near the upper end 18p of the upper section 12p is threaded, a portion of the inner peripheral surface formed by the opening 22p and generally near the lower end 20p of the upper section 12p also being threaded, as shown in FIG. 6.
The intermediate section 16p is constructed exactly like the intermediate section 16 shown in FIG. 1, except the intermediate section 16p does not include tapered portions similar to the tapered portions 44 and 46 (shown in FIG. 1) and a portion of the inner peripheral surface formed by the opening 42p and generally near the upper end 38p of the intermediate section 16p is threaded, a portion of the inner peripheral surface formed by the opening 42p and generally near the lower end 40p of the intermediate section 16p also being threaded, as shown in FIG. 6.

An opening 118 is formed through the upper section 12t, the opening extending axially through the upper section 12t and intersecting the upper and the lower ends 114 and 116. A tapered portion 120 is formed on the upper section 12t generally near the lower end 116, the tapered portion 120 being tapered inwardly as shown in FIG. 7. A portion of the inner peripheral surface formed by the opening 118 generally near the upper end 114 of the upper section 12t is threaded. A pair of openings 122 and 124 are formed through the upper section 12t, each of the openings 122 and 124 being disposed generally near and spaced a distance from the lower end 116 and the openings 122 and 124 being axially aligned. The opening 118 cooperates to form a compartment 125 for storing items in a manner similar to that described before.
The intermediate sections 16t and 16w are each identical in construction and each includes an upper end 126, a lower end 128 and an opening 130 extending axially therethrough and intersecting the upper and the lower ends 126 and 128 (the various portions of the intermediate sections 16t and 16w also being designated via the references "a" and "b", respectively, for identification). A tapered portion 132 is formed on each of the intermediate sections 16t and 16w, generally near the lower end 128.
A pair of openings 134 and 136 are formed through each of the intermediate sections 16t and 16w. The openings 134 and 136 generally are aligned and spaced about 180 degrees apart, the openings 134 and 136 being disposed generally near and spaced a distance from the upper end 126. A second pair of openings 138 and 140 are formed through each of the intermediate sections 16t and 16w. The openings 138 and 140 generally are aligned and spaced about 180 degrees apart, the openings 138 and 140 being disposed near and spaced a distance from the lower end 128.
The lower section 14t is constructed similar to the lower section 14 shown in FIG. 1. The lower section 14t has an upper and a lower end 142 and 144. An opening 146 is formed through the lower section 14t, the opening 146 extending axially through the lower section 14t and intersecting the upper and the lower ends 142 and 144. A portion of the inner peripheral surface formed by the opening 146 and generally near the lower end 144 of the lower section 14t is threaded, as shown in FIG. 7. A pair of openings 148 and 150 is formed through the lower section 14t. The openings 148 and 150 generally are aligned and spaced about 180 degrees apart, the openings 148 and 150 being disposed generally near and spaced a distance from the upper end 142 of the lower section 14t.
The connectors 112 are identical in construction and each connector includes a tube 152 having an opening 154 extending axially therethrough and intersecting the opposite ends thereof. A first locking pin 156 is slidably disposed within the opening 154 of the tube 152. The first locking pin 156 includes a base 157 and a projection 158 which extends a distance from the base 157. A second locking pin 160 is slidably disposed within the opening 154 of the tube 152. The second locking pin 160 includes a base 161 and a projection 162 which extends a distance from the base 161. The locking pin 162 is slidably disposed generally near the opposite end of the tube 152 with respect to the disposition of the first locking pin 156 in the tube 152.
A spring 164 is disposed between the first and the second locking pins 156 and 160. One end of the spring engages the base 157 of the first locking pin 156 and the opposite end of the spring 164 engages the base 161 of the second locking pin 160. The spring 164 biases each of the locking pins 156 and 160 in opposite directions and in a direction generally out of the opening 154 in the tube 152.
The survival stick 10t includes a pair of caps 170 and 172 which are constructed exactly like the caps 100 and 102 shown in FIG. 6 and described in detail before. The cap 170 is threadedly inserted through the upper end 114 and into the opening 118 of the upper section 12t to threadedly secure the cap 170 to the upper section 12t. The cap 172 is threadedly inserted through the lower end 144 and into the opening 146 of the lower section 14t to threadedly secure the cap 172 to the lower section 14t.
As shown in FIG. 7, the connector 112t is disposed within the opening 118 of the upper section 12t and spaced a distance from the lower end 116 of the upper section 12t. The connector 112t is positioned such that the projection 158 of the first locking pin 156 projects through the opening 124 in the upper section 12t to a position wherein the base 157 engages a portion of the upper section 12t generally near the opening 124 therethrough and the projection 162 of the second locking pin 160 extends through the opening 122 in the upper section 12t to a position wherein the base 161 of the second locking pin 160 engages a portion of the upper section 12t generally near the opening 122. In this position, the tube 152 is securedly connected to the upper section 12t and the spring 164 of the connector 112t functions to biasingly move the first and the second projections to a position wherein the bases 157 and 161 of the first and the second projections 158 and 162, respectively, each engage a portion of the upper section 12t with the projection 158 extending through the opening 124 and a distance beyond the outer wall of the upper section 12t and with the projection 162 extending through the opening 122 a distance beyond the outer wall of the upper section 12t. The first and the second locking pins 156 and 160 cooperate to secure the connector 112t in an assembled position within the opening 118 of the upper section 12t via the projections 158 and 162 extending through the openings 124 and 122, respectively.
The connector 112w is disposed in the opening 130t of the intermediate section 16t to a position wherein the projection 158 of the first locking pin 156 extends through the opening 140 to a position wherein the base 157 engages a portion of the intermediate section 16t generally about the opening 140 and wherein the projection 162 extends through the opening 138 in the intermediate section 16t to a position wherein the base 161 engages a portion of the intermediate section 16t generally about the opening 138. The spring 164 biases each of the locking pins 156 and 160 in opposite directions to maintain the projections 158 and 162 extending through the openings 140 and 138, respectively. Thus, the first and the second locking pins 156 and 160 cooperate to secure the connector 112w within the intermediate section 16t via the engagement between the locking pins 156 and 160 and the intermediate section 16t.
The connector 112x is disposed within the opening 130w of the intermediate section 16w and positioned therein such that the projection 158 of the first locking pin 156 extends through the opening 140w and the projection 162 on the second locking pin 160 extends through the opening 138w. The spring 164 biases the first and the second locking pins 156 and 160 to maintain the projections 158 and 162 extending through the openings 140w and 138w, respectively. Thus, the first and the second locking pins 156 and 160 cooperate to secure the connector 112x positioned within the opening 130w of the intermediate sections 16w.
After the cap 170 has been threadedly secured to the upper section 12t, the tapered portion 120 of the upper section 12t is inserted through the upper end 126t of the intermediate section 16t to a position wherein the openings 122 and 124 in the upper section 12t are aligned with the openings 134t and 136t in the intermediate section 16t. When the tapered portion 120 of the upper section 12t is inserted into the opening 130t of the intermediate section 16t, the first and the second locking pins 156 and 168 each engage a portion of the intermediate section 16t. The engagement between the first and the second locking pins 156 and 160 and portions of the intermediate section 16t result in the first locking pin 156 being biased in a direction generally toward the second locking pin 160 and the second locking pin 160 being biased in a direction generally toward the first locking pin 156 to a position wherein the tapered portion 120 can be inserted into the opening 130t of the intermediate section 16t. After the tapered portion 120 of the upper section 12t has been inserted into the opening 130t to a position wherein the openings 122 and 124 in the upper section 12t are aligned with the openings 134t and 136t, respectively, in the intermediate section 16t, the spring 164 in the connector 112t biases the first locking pin 156 to a position wherein the projection 158 extends through the openings 124 and 136t and the spring 164 biases the second locking pin 160 to a position wherein the projection 162 extends through the opening 122 and 134t. In this position, the upper section 12t is connected to the intermedite section 16t by the projections 158 and 162.
After the upper section 12t has been removably connected to the intermediate section 16t by the connector 112t, the tapered portion 132t of the intermediate section 16t is inserted through the upper end 126w and into the opening 130w of the intermediate section 16w to a position wherein the openings 138t and 140t in the intermediate section 16t are aligned with the openings 134w and 136w in the intermediate section 130w. In this position, the spring 164 biases the first locking pin 156 to a position wherein the projection 158 extends through the aligned openings 140t and 136w and biases the second locking pin 160 to a position wherein the projection 162 extends through the aligned openings 138t and 134w. Thus, the intermediate section 16t is connected to the intermediate section 16w by the projections 158 and 162 extending through the aligned openings 136w and 140t and 134w and 138t, respectively.
After the upper section 12t, the intermediate section 16t and the intermediate section 16w have been connected as described before, the tapered portion 132w is inserted through the upper end 142 and through the opening 146 of the lower section 14t to a position wherein the opening 140w is aligned with the opening 150 and the opening 138w is aligned with the opening 148. In this position, the spring 164 biases the first locking pin 156 to a position wherein the projection 158 extends through the aligned openings 140w and 150 and the spring 164 biases the second locking pin 160 to a position wherein the projection 162 extends through the aligned openings 138w and 148. Thus, the intermediate section 16w is connected to the lower section 14t by the projections 158 and 162 extending through the aligned openings 140w and 150 and the aligned openings 138w and 148, respectively.
The various sections of the survival stick 10t are disconnected to gain access to the various compartments in a similar manner. For example, if it is desired to disconnect the upper section 12t from the intermediate section 16t, a force is applied to the projections 158 moving the projection 158 out of the opening 136t and a force is applied to the projection 162 moving the projection 162 out of the opening 134t. In this position, the upper section 12t can be removed from the intermediate section 16t. As mentioned before, the remaining sections are separated in a manner similar to that described before with respect to the upper section 12t and the intermediate section 16t.
A threaded opening 174 is formed throughout the upper section 12t, the opening 174 being positioned generally midway between the upper and the lower ends 114 and 116. A portion of the outer peripheral surface of the intermediate section 16t generally near the upper end 126 is threaded. The upper section 12t can be disconnected from the intermediate section 16t and the threaded upper end 126 of the intermediate section 16t can be threadedly inserted into the opening 174, thereby connecting the upper section 12t to the intermediate section 16t to form a crutch-like structure for reasons described before.
It should be noted that, although the various survival sticks have been described herein as including two intermediate sections, it is contemplated that a commercial survival stick may include more or less intermediate sections, as desired in a particular construction.
Changes may be made in the construction and operation of the various elements and assemblies described herein without departing from the spirit and the scope of the invention as defined in the following claims.
