Description
FIELD OF THE INVENTION
The present invention relates to tree stands, and more particularly to a tree stand having improvements in both the climbing or seat supporting section and the platform or foot supporting section.
DESCRIPTION OF THE PRIOR ART
Tree stands, also known as tree climbing stands, are well known in the art, as illustrated by U.S. Pat. No. 4,331,216 to Amacker. As noted in the aforementioned Amacker patent, prior art tree stands have generally been considered to be of two basic types; those comprised of a single tree climbing frame or climber, and those which employ two climbing frames or elements. The Amacker patent describes a two-part tree stand which has an upper, climbing, or seating section and a lower, platform, or foot supporting section. The platform has a strong expanded metal mesh secured to a rigid frame for supporting the user when standing on the platform.
Other two-part tree stands are illustrated by U.S. Pat. No. 3,955,644 to Dye and U.S. Pat. No. 4,802,552 to Williams. These two patents are characterized by their use of the lower, climbing section as a seat support section and by their use of an extremely simple upper, climbing member which has no utility other than serving as a support for the arms of the user of the stand when the tree is being climbed.
Each of these tree stands, while they may be useful for the intended purpose, have the drawbacks of being long, relatively heavy, and confined to a limited manner of using the tree stands.
SUMMARY AND OBJECTS OF THE INVENTION
In view of the foregoing limitations and shortcomings of the prior art devices, as well as other disadvantages not specifically mentioned above, it should be apparent that there still exists a need in the art for a tree stand which is shorter, less cumbersome to use, lighter weight and more flexible than conventional tree stands.
It is, therefore, a primary object of this invention to fulfill that need by providing a tree stand which is compact.
More particularly, it is an object of this invention to provide a tree stand which, while being compact, is light in weight.
It is another object of this invention to provide a tree stand which is flexible in its construction so that it can perform the function of a number of models of tree stands currently on the market.
Yet another object of this invention is to provide a tree stand, which while being compact and light in weight is extremely sturdy in construction and safe to use.
Still another object of this invention is to provide a tree stand in which the upper or climbing section is adjustable as to its length.
A further object of the invention is to provide a tree stand in which the upper, climbing section is convertible from a seating section to a simple hand climber.
A further object of the invention is to provide a tree stand having a lower, foot supporting section which is capable of being reduced in length.
Yet a further object of the invention is to provide such a lower, foot supporting section which, while being compact in length, is readily transportable.
Briefly described, the aforementioned objects are accomplished according to the invention by providing a tree stand apparatus having a seating section which includes a pair of longitudinally extending side members, means for gripping a tree connected at one end of the side members, and a cross member adapted to be mounted to the opposite end of the side members. Means for mounting the cross member on the side members allow adjustment of the length of the cross member with respect to the side members to allow adjustment of the length of the tree stand. Additionally, the cross member may be completely removed from the side members, providing a simple apparatus which may be used as a hand climber, or, when used as a seating section allows freedom of movement of the seated user's legs. In this latter situation, means are provided for retaining the cross member on the seating section in a vertical orientation.
The aforementioned objects are further accomplished according to the invention by providing a tree stand foot supporting section having a generally rectangular frame and a foot supporting platform supported by said frame. The rectangular frame is divided into two frame sections, detachably connected with one another, so that the frame may be assembled for climbing and use as a tree stand, or disassembled to reduce the length of the foot supporting section for transportation and storage. Means are provided on one of the two sections for retaining and locking the two sections together in the disassembled state, thereby providing a compact unit for transportation and storage.
With the foregoing and other objects, advantages and features of the invention that will become hereinafter apparent, the nature of the invention may be more clearly understood by reference to the following detailed description of the invention, the appended claims and to the several views illustrated in the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now in detail to the drawings wherein like parts are designated by like reference numerals throughout, there is illustrated in FIG. 1(A) a tree stand which is designated generally by reference numeral 10, having an upper, climbing, seat supporting section generally designated by reference numeral 20, and a lower, foot supporting, platform section generally designated by reference numeral 40.
Upper, Climbing, Seating Section
Referring now to FIGS. 2, 3, 5(A), 5(B) in conjunction with FIGS. 1(A), 1(B), the upper, climbing, or seating section 20 will be described in greater detail.
Climbing or seating section 20 comprises a generally rectangular frame having a first pair of side members 26 which extend longitudinally away from the tree T when the seating section 20 is in use. Means for gripping tree T, in the preferred embodiment a V-shaped yoke 21, is securely fastened, such as by weldment, to one end of each of the side members 26. A cross member 22 is detachably connected with side members 26 so as to provide rigidity for the seating section 20 when a user is seated thereon.
More specifically, cross member 22 is formed from a piece of hollow tubular stock having a generally rectangular or square cross section, the tubular stock being bent at two places to form a U-shaped member having a base 24 and two longitudinally extending legs 30.
As seen in FIGS. 1(A), I(B) and FIG. 3, side members 26 are also formed from hollow tubular stock having a generally rectangular or square cross section, with the tubular stock being so dimensioned as to allow legs 30 of cross member 22 to fit telescopingly within side members 26.
Seating section 20 is provided with a seat 38 which supports the user in a seated position on the tree stand when in use, and also supports the user in a seated position when the tree stand is being climbed, with the user in a seated position facing away from the tree. In the illustrated embodiment, seat 38 is made from a sturdy piece of fabric material, such as canvas, which has been stretched over the two side members 26, and with the ends of the fabric being firmly stitched together, so as to provide a unitary seating structure. This fabric seat 38 allows for an extremely right weight, yet sturdy and durable seat for the seating section. Of course, it will be apparent to those skilled in the art that any conventional type of seat may be readily used. in connection with seating section 20, such as, for example, the seat illustrated in my copending U.S. Pat. application Ser. No. 07/336,793 (Notice of Allowance issued June 6, 1990, U.S. Pat. No. not yet assigned).
In accordance with the invention, means are provided on cross member 22 and side members 26 for locking cross member 22 on seating section 20 when the cross member 22 is fully extended for use, as illustrated in FIGS. 1(A) and 5(A).
The locking means provided on cross member 22, generally designated by reference numeral 60 in FIG. 5(A) and as most particularly shown in FIG. 7, comprises a set of corresponding apertures 62,64 located in one of side members 26 and one of legs 30 of cross member 22. Locking means 60 also includes a unitary push spring 66 such as Valco (of Cleveland, Ohio) No. 0183-250, which is a one-piece U-shaped member in which the pin is integrally formed in one end of the spring. The spring may thus be readily inserted and removed from within the telescoping tubular members. Such a locking means is more fully described in my aforementioned U.S. Pat. application Ser. No. 07/498,401, and is incorporated herein by reference.
Cross member 22 may also be provided with an additional cross bar or cross support piece 23, disposed perpendicularly to legs 30 and parallel to base 24 and firmly connected to each of legs 22, such as by weldment, in the vicinity of base 24. Cross bar 23 provides additional rigidity for cross member 22 thereby further improving the safety of seat supporting section 20.
In a similar fashion, a yoke support bar 25 extends between side members 26, perpendicularly thereto, and firmly secured such as by weldment to both of side members 26 as well as to V-shaped yoke 21. A strip of hard rubber cushioning material 27 may be applied to the side of yoke 21 which engages the tree, thereby protecting the tree in compliance with ecological principles and applicable state laws. Of course, it will be appreciated by those skilled in the art, that a variety of means of protecting the tree may be employed in the yoke of the present inventive apparatus, consistent with the scope of the invention.
Also provided as an aid for both climbing and firm support on the tree are an additional pair of side members 28. At one end thereof, side members 28 are pivotally mounted to side members 26. This pivotal mounting may be done in a variety of ways, but, in the preferred embodiment is performed by the use of a relatively small but sturdy plate 37 (FIG. 5A) which is firmly secured, as by weldment, to one end of each side member 26 and pivotally mounts one end of each side member 28, as by means of a nut and bolt connection 35.
At a location on side members 28 which is more proximate the tree gripping means, one end of a strut 34 is firmly yet pivotally connected, as by means of a rivet, to each of side members 38. The other end of strut 34 is similarly pivotally connected to a relatively short rectangularly cross section tubular member 33. Tubular member 33 and the end of side member 26 at which the tree gripping means is located are provided with locking means similar to locking means 60 illustrated in FIG. 7. Since the locking means for tubular members 33 and side members 26 have been previously explained in great detail, no further explanation is necessary at this point.
Finally, side members 28 of seating section 20 are provided with additional means for gripping a tree in the form of a blade 80. Blade 80 may be any one of a number of known blades, and, in the illustrated embodiment, is a V-shaped flat piece of stock metal which has been provided with serations on the inside surface of the V-shape and with apertures at the ends of the V for mounting to the side members 38. Blade 80 is adjustably mounted on side members 28 by mounting means 70, illustrated in detail in FIG. 8 in conjunction with FIG. 2.
Adjustable mounting means 70 include an easy-grip plastic knob 72 having a stepped recess 74 in which a threaded metallic insert 76 is press fit. A standard threaded bolt 78 is engagable with threaded insert 76 through adjustment apertures located at the tree gripping ends of side members 28 so as to provide a secure, yet adjustable connection of blade 80 to seating section 20.
It will be appreciated that any known means may be used for securing blade 80 to seating section 20. It should also be noted that blade 80 may be provided with a suitable coating such as rubber or plastic in order to provide an environmentally sound tree gripping means which is consistent with state laws.
Lower, Platform, Foot Supporting Section
Referring now to FIGS. 4, 6(A), 6(B) in conjunction with FIGS. 1(A), 1(B), the lower, platform, or foot supporting section 40 will be described in greater detail.
Platform or foot supporting section 40, similarly to seating section 20, comprises a generally rectangular frame. Foot supporting section 40 is divided into two frame sections 42 and 52.
Frame section 42 includes two longitudinally extending rectangularly cross section shaped tubular side members 44. Means for gripping tree T are provided at one end of side members 44, which, in the preferred embodiment, takes the form of a V-shaped yoke 41 which has substantially the same construction as yoke 21 previously described in connection with the upper section 20. V-shaped yoke 41 is firmly connected to the one end of side members 44 such as by means of weldment, and is similarly connected at the point of the V to a cross support bar 43 which extends perpendicularly to side members 44 and is also firmly connected thereto as by weldment, so as to provide structural rigidity for the tree gripping means associated with side members 44. An additional cross support bar 45 is perpendicularly disposed between side members 44 and similarly firmly connected thereto at the ends of side members 44 opposite the tree gripping means. According to this arrangement, great structural rigidity and safe platform support are provided in the frame section 42.
Foot supporting section 40 is provided with means for detachably connecting frame sections 42 and 52 with one another, so that the frame may be assembled for climbing and use as a tree stand, and may also be disassembled to reduce the length of the foot supporting section for transportation and storage. Also, means are provided for locking the assembled sections in position when the frame is in use, and for holding the disassembled sections together as a unit when transported or stored.
Frame section 52, similarly to cross member 22 of foot supporting section 20, is formed from hollow tubular stock having a generally rectangular or square cross section, the tubular stock being bent at two places to form a U-shaped member having a base 54 and two longitudinally extending legs 56.
Also, as seen in FIGS. 1(A), 1(B) and FIG. 4, side members 44 are formed from hollow tubular stock with the tubular stock being so dimensioned so as to allow legs 56 of frame member 54 to fit telescopingly within side members 44.
In accordance with the invention, means are provided on frame section 52 and side members 44 for locking frame section 52 on foot supporting section 40 when the frame section 52 is assembled for use, as illustrated in FIGS. 1(A), 1(B), 4 and 6(A).
The locking means, generally designated by reference numeral 60 in FIGS. 4 and 6(A) and most particularly in FIG. 7, comprises a set of corresponding apertures 62,64, located in one of each of side members 44 and one of legs 56 of frame section 52. Locking means 60, one of each of which is provided on each of frame sections 42,52 of section 40, are identical with that earlier described in connection with section 20.
While it will be appreciated that the locking means 60 are provided in the preferred embodiment on only one side of seating section 20 for convenience in use of the seating section and two locking means 60 are provided on foot supporting section 40, in order to ensure a secure and safe connection of the two frame sections of the foot supporting section, it will be appreciated by those skilled in the art that any combination of locking means 60, such as the provision of a single locking means on one or the other sides of the seating section and frame section, or two locking means, one on each side of either the seating section or foot supporting section may be provided, consistent with the scope of the invention.
Frame section 52 is also provided with an additional cross bar or cross support piece 57, disposed perpendicularly to legs 56 and parallel to base 54 and firmly connected to each of legs 56, such as by weldment, spaced apart from base 54. A longitudinal support bar 55, disposed parallel to legs 52, substantially equidistantly therebetween, is similarly firmly connected to base 54 and cross bar 57. Cross bar 57 and longitudinal support bar 55 provide additional rigidity thereby improving the safety of foot supporting section 40.
Similarly, frame section 42 is provided with a longitudinal support bar 47 connected in a manner similar to longitudinal support bar 55 to provide additional rigidity to frame section 42.
Each of frame sections 42 and 45 are provided with an expanded metal mesh 49,59, respectively, to provide the platform for the tree stand user, as is known in the art.
Also provided on frame section 42 as an aid for both climbing and firm support on the tree are an additional pair of side members 46. Similar to the additional pair of side members 28 of seating section 20, side members 46 are pivotally mounted to side members 44 by means of a sturdy plate and pivotal nut and bolt connection (unnumbered). Strut, tubular members and locking means 60 identically with those described and illustrated hereinabove with respect to the seating section are provided for side members 44 and 46 of foot supporting section 40. Since the pivotal connection and strut collapsing construction of foot supporting section 40 is identical with that of seating section 20, it is not necessary to describe these elements in further detail.
Similarly, additional means for gripping the tree T in the form of a blade 80 and adjustable mounting means 70 are provided on side members 46.
Further in accordance with the invention, foot supporting section 40 is provided with holders 53, one of each of which is welded to the underside of side members 44, which, in the preferred embodiment, are proximate the ends of the side members connected to yoke 41. Holders 53 are formed from tubular rectangularly cross section shaped stock similar in dimension to side members 44. Holders 53 are provided with apertures in order to receive the free ends of legs 56 enabling locking means 60 to lock legs 56 to the holders, thereby locking frame elements 42 and 45 together as a unit for ready transportation and convenient storage.
Tree Stand Operation
Referring once again to FIG. 1(A), the tree stand 10 is illustrated in climbing and use position on the tree T. In this position, seating section 20 is in its fully extended state, with cross member 22 assuming the position illustrated in phantom arrow E of FIG. 2 and in the full line position illustrated in FIG. 5(A). Further, in this extended, use- position, locking means 60 is fully engaged, insuring that cross member 22 is securely held on side members 26. Further, foot supporting section 40 is in its assembled position, illustrated in full line in FIG. 4 and in full line in FIG. 6(A). In this position, locking means 60 are also engaged so that sections 52 and 42 are securely held to form a safe platform. In this condition, the tree stand 10 can be used as a sitting tree stand or the stand may be used to climb up and down the tree in a "sit-down" manner using bail 46B as is known in the art.
Referring now to FIG. 1(B), tree stand 10 is shown in the position in which cross member 22 has been completely removed from side members 26, rotated 90.degree. downwardly, and then inserted into one of the hollow tubular side members 26, so that cross member 22 assumes a vertical orientation, yet is still secured to the seating section 20. In this arrangement, the user can easily stand without any impediment from cross member 22. This condition is extremely desirable for the archer or bow hunter who desires to lean forward. Also in this condition, a seated user of tree stand 10 will be free to swing his or her legs without interference from cross member 22, thereby providing an extremely comfortable seat.
By way of further explanation, reference is made to FIG. 2 in which cross member 22 is shown completely removed from side members 26 in the position of phantom arrow R.
When the user has descended from the tree, and it is desired to disassemble the tree stand for transportation and eventual storage, each of the two sections 20,40 are reduced in length and collapsed.
Referring specifically to FIG. 2, it will be seen that cross member 22, as illustrated in the full line position, has been telescopically reduced in length by releasing locking means 60 and sliding cross member 22 toward the tree gripping end of the seating section 20.
Referring to FIG. 5(B) in conjunction with FiG. 5(A), it will be seen that section 20 is not only reduCed in length but is collapsed, locking means 60 retaining members 33 on side members 26 having been released, and struts 34 having been pivoted on both side members 26 and members 33. This operation is illustrated in phantom in FIG. 5(A).
Similarly, foot supporting section 40 is first reduced in length by detaching frame sections 42 and 52, as illustrated in phantom in FIG. 4.
Referring now to FIG. 6(B), the seat supporting section is shown in its disassembled, collapsed state, in which frame section 52 is carried by and locked in holder 53 for transportation and storage. This condition is reached by releasing locking means 60 connecting frame sections 42 and 44, illustrated in full line in FIG. 6(A), then removing frame section 52 and positioning it in the phantom position illustrated in FIG. 6(A). Additionally, side members 46 are pivoted from the position shown in FIG. 6(A) to that shown in FIG. 6(B) in a manner similar to that described with respect to side members 28 of seating section 20 in FIGS. 5(A) and 5(B).
The two compact, collapsed sections 20 and 40 may then be tied or bundled together as a unit or kept separated, at the convenience of the user, for transportation and eventual storage.
In a preferred construction, the length of the upper and lower sections can be shortened by the present invention from about 42 or 44 inches in its fully extended condition (similar to other, more conventional stands) to about 32 inches when the removable sections 20,40 are removed.
Hand Climber Operation
Referring now to FIGS. 1(B) and 2, it will be seen that it is possible to readily remove cross member 22 from upper, climbing, seating section 20. As particularly illustrated in FIG. 2 in the position of phantom arrow R, the remaining section 20, cross member 22 having been removed, is particularly adapted for use as a hand climber. When section 20 is used as a hand climber, the function of which is well known in the art, section 20 may either be used by itself, in which case the user "skinnies" up the tree or may be used in conjunction with a foot supporting section such as foot supporting section 40, in the fashion illustrated in the aforementioned Dye and Williams patents.
In accordance with the invention, then, the described apparatus has a great versatility of use and performs the function of at least seven different models of tree stands currently on the market.
It will also be apparent that although it is contemplated that the upper or climbing section 20 will be used together with the lower or foot supporting section 40, each of the sections may be used separately, or, with other conventional tree stand devices. For example, the lower section 40 may be used with hand climbers other than the hand climber 20 of the present invention.
Although certain presently preferred embodiments of the invention have been described herein, it will be apparent to those skilled in the art to which the invention pertains that variations and modifications of the described embodiment may be made without departing from the spirit and scope of the invention. Accordingly, it is intended that the invention be limited only to the extent required by the appended claims and the applicable rules of law.
