Detailed Description of the Preferred Embodiments
The present invention is drawn to a portable hunting stand or observation post 10. Referring now specifically to FIG. 1, the first embodiment of the hunting stand 10 is shown attached to a tree 12. A seat platform 14 and separate standing platform 16 are shown. A hunter 15 is shown standing on the separate standing platform 16. The hunting stand 10 is connected to the tree 12 by a nylon strap 18 connected to a C-shaped pivotable element 20. A wheel 22 is rotatably mounted on the bottom of the stand 10 which gives the stand its portability.
Referring now to FIG. 2 the hunting stand 10 is shown by a front elevational view. The ladder assembly is shown in three sections, an upper section 22, an intermediate section 24, and a lower section 26. Each section has a right 28 and a left rail 30 associated with it. The ladder assembly is foldable at the intersection of the of the upper section and the intermediate section, and it is also foldable at the intersection of the intermediate section and the lower section. The folding action is caused by rotation about a central pin 32. Several variants of the locking mechanism located about the central pin 32 will be presented later in this discussion.
FIG. 3 shows a variant of the wheel assembly 31 which includes two wheels 34. These wheels 34 are mounted each on a shaft member 36. The two wheel variant adds stability when utilizing the stand in its carcass carrier capacity.
The upper section 22 of the ladder assembly has both a standing platform 16 and a separate seat platform 14. Referring now to FIG. 4, the seat platform 14 is shown attached to the right 28 and the left rail 30 of the upper section 22 of the ladder assembly. The standing platform 16 is located below the seat platform 14 and is connected to the seat platform 14 by a right 40 and a left bar member 42. The standing platform 16 is also connected to the right 28 and left rail 30 of the upper section 22 of the ladder assembly.
A pivotable C-shaped element 20 is connected to the end of the upper section 22 of the ladder assembly. This element 20 has a nylon strap 18 connected permanently to its right hand side and a strap receiving device 38 located on its left hand side. The C-shaped element 20 is placed proximal to a tree trunk 12 or limb. The nylon strap 18 encircles the tree portion 12 and is tightened by a ratchet and pawl type mechanism located on the strap receiving device 38.
The hunting stand and observation post 10 may be converted into a carcass carrier by folding the ladder assembly about its fold or rotation points. The converted stand is shown in FIG. 5 with a game animal 44 being taken by the hunter 15 to another location. The lightweight construction of the stand 10, in addition the mounted wheel 22, permits the hunting stand, when folded, to be easily carried over most terrain.
FIGS. 6-8 shows a first variant of a mechanism designed to lock the ladder assembly in both a folded and unfolded state. This first variant 50 involves a cam 58 which pulls the upper rail portion 69 together with the lower rail portion 68. A pin has a head 66 and a shank 67 and connects the two rail portions (68, 69). A spring 64 is nested on the shank 67. A cam 55 is pivotably connected to the end of the shank 67 by a small pin element 58. The lower rail portion 68 has two male members 60 which matingly connect to the upper rail portion 69. Upper rail portion 69 has a plurality of holes 62 designed to receive the male members 60. When the locking mechanism is not engaged the upper portion 60 can rotate about pin shank 66. FIG. 7 shows the mechanism 50 in the unlocked position whereas FIG. 8 shows the mechanism in its locked position.
FIGS. 9-11 show a second and preferred embodiment of the mechanism 70 designed to lock the ladder assembly in both a folded and unfolded state. A thumbscrew 72 is provided which will secure the upper rail portion 78 to the lower rail portion 79. The thumbscrew 72 is designed to mate with one of a plurality of holes 76. A central pin 74 permits rotation of the upper rail portion 78 with respect to the lower rail portion 79. A washer 75 is positioned in between the head of the thumbscrew 72 and one of the plurality of holes 76. FIG. 10 shows the mechanism 70 in the unlocked position and FIG. 11 shows the mechanism in the locked position.
FIGS. 12 and 13 shows a third variant of the mechanism 90 designed to lock the ladder assembly in both a folded and unfolded state. A plate 96 has two male members 206 and a central pin 98 located on it. The central pin passes through the lower rail portion 92 and the upper rail portion 94. At the end of the shaft of the central pin 98 a cam 100 is located. The cam 100 is secured pivotably to the shaft of the central pin 98 by element 102. A plurality of holes 104 are designed to receive male members 106. These male members 106 are brought into two of the holes 104 through actuation of the cam member 100. A spring 106 is nested on the shaft of the central pin 98 between plate 96 and lower rail portion 92. The mechanism 90 is shown in its locked position in FIG. 12, and is shown in its unlocked position in FIG. 13.
FIG. 14 illustrates the mechanism which holds the hunting stand 10 to the tree 12. A nylon strap 18 is permanently affixed to the right hand side of the c-shaped element 20 at point 19. The C-shaped element 20 engages the tree portion and the nylon strap encircles that portion. It is important to note that C-shaped element 20 is rotatable about its stub axle mounting 21, as seen in FIG. 1, and also about a second, transverse axis defined by a dowel 25, which mounts stub axle mounting 21, which in turn is rotatably mounted in the upper ends of upper rails 28 and 30 by pin axles 27, as best seen in FIG. 14. With reference to FIG. 4, rotation of dowel 25 upwardly may be limited, so that the user does not try to encircle strap 18 about a horizontal tree limb that might extend over and block seat platform 14.
The distal end of the nylon strap 21 is engaged by a strap tightening device 38. This strap tightening device includes a spring loaded pawl 112 which engages a ratchet 110 about a spindle 111. The nylon strap is thus tightened by actuation of the ratchet. The ratchet 110 and pawl 112 as well as the spindle 111 are conventional.
While a ratchet and pawl assembly and spindle are shown for securing the upper part of the stand to a tree, other securing arrangements are feasible. For example, a length of cord tied to the two ends of element 20 can be used, or a convenient length of cable or link chain could be employed.
A self standing hunting and observation stand 120 is presented as a second embodiment of the invention. A ladder assembly is provided with an upper element 124 and a lower element 126. The elements fold about each other at pivot or fold points 130. Each of the ladder elements include a right rail 140 and a left rail 142. A wheel 122 is provided on the lower element 128 and is mounted on a shaft 123. The pivot or fold points 130 include the previously described locking mechanisms which permit the stand 120 to be locked in either a folded or unfolded position.
A right 132 and a left leg 134 are mounted to the upper element 122 of the ladder assembly by a small C-shaped element 146. This element rotates about stub axle 21, as in the first embodiment. Similarly, dowel or top ladder rung 25 is provided which is rotatably mounted by pin axles in the upper ends of the rails 140 and 142.
The right 132 and the left leg 134 each have a point of rotation 135 which permits the legs 132, 134 to be folded generally parallel one another so as to lie to either side of wheel 122 when the invention is collapsed for transport; the folded appearance is about the same as that in the first embodiment as shown in FIG. 5. A support member 137, such as a length of plastic coated cable, connects the right leg 132 to the left leg 134. In this manner, support member 137 provides additional structural stability to the tripod formed by the two legs and the ladder assembly.
Hinges 147 are provided on the small C-shaped member 146 which permit the right 132 and left leg 134 to rotate. The right 132 and left leg 134 are connected to the C-shaped member 146 by being telescoped into open ends thereof as shown at 148. Preferably, hinges 147 are otherwise conventional coil spring loaded hinges so as to urge the C-shaped member 146 into the open disposition shown in FIGS. 15 and 16. Also, C-shaped member may be provided with the strap, ratchet and pawl mechanism and spindles of the first embodiment, so the user has the option of either attaching the invention to a tree trunk or limb or employ the tripod configuration of this embodiment.
This embodiment of the hunting stand 120 may be erected anywhere and does not depend on a tree for support. The two legs 132, 134 and the ladder assembly form a tripod from which one can hunt or observe game.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
