Detailed Description of the Preferred Embodiment
The instant invention provides a support or stand that provides a hunter or observer with an elevated vantage point for observing a large area of terrain. The stand may be configured as a hunter's tripod stand. It is advantageous for a hunter to use an elevated stand, as the hunter may observe a larger area of terrain with fewer obstructions than a hunter on the ground.
According to the instant invention simplified components are used that substantially assemble and disassemble the hunter's tripod stand without the use of tools. As shown in FIGS. 1-3, a hunter's tripod stand 10 may include a rotatable body supporting member or chair 20 rotatably connected to a support base. The rotatable chair may include a seat 22 and a backrest 24 substantially perpendicular to the seat. According to the preferred embodiment, the chair is formed from lightweight molded plastic and may have a plurality of strengthening ribs.
The rotatable chair may include a chair platform 26 having a threaded fastener or chair bolt 28 attached thereto by welding for rotatably securing the chair to the support base. The support base may include a base platform 30 and a plurality of legs 42, 52, 62. Each of the legs may include a foot rest segment that combines to substantially define a ring or circle of about 360.degree..
According to the preferred embodiment, the legs are formed from hollow, square steel tubing to maximize the strength of the structure without excessively increasing the weight of the structure. According to the preferred embodiment, the hollow, square tubing may have a 1" nominal width and a 1/16" wall thickness.
First leg 42 may have a plurality of rungs or foot steps 48 spaced along the leg for climbing the support base. The first leg may also exhibit foot rests 44a, 44b that may be welded or otherwise attached to the first leg. According to the preferred embodiment, anchor element 46 is configured as a downwardly directed L-shaped bracket. A vertical portion of the bracket functions as a spike or ground piercing element, and a horizontally directed portion of the bracket functions as weight distributing element that is wider than the leg and advantageously supports the device when the stand is located on soft or wet earth.
The support base may be configured as a hunter's tripod stand having one permanently attached leg 42 and two detachable legs 52, 62. According to the preferred embodiment, legs 52, 62 may also include an L-shaped anchor element 56, 66, respectively, for securing a respective leg to the ground or like supporting surface, as described above with regard to the first leg.
A pair of sleeves 34, 36 may be connected to the base platform 3 of the support base for receiving and frictionally securing each detachable leg to the base platform by use of a respective threaded fastener 34a, 36a. According to the preferred embodiment, each sleeve is configured as a square steel tubing with a 11/4" nominal width and a 1/16" wall thickness.
Second leg sleeve 34 may be configured as a hollow tube having an aperture (not shown) disposed in the side of the hollow tube. A threaded nut (not shown) may be welded over the aperture, so a hole in the threaded nut is co-extensive with the aperture in the sleeve. In this manner a T-shaped threaded fastener 34a may be threaded into the threaded nut and contact second leg 52. Alternatively, a threaded aperture (not shown) may be located in the sleeve to directly accept the threaded fastener.
The permanently attached first leg 42 may include a pair of threaded elements or storage rods 72, 74 for securing the detachable legs to the permanently attached leg, when the elevated stand is in a storage configuration. Upper storage rod 72 and lower storage rod 74 may include a wing nut or storage rod fastener 76.
The chair 20 may be rotatably secured to the support base by a threaded connection. A chair bolt 28 may be threaded into a platform nut 32 that is welded or otherwise connected to platform 30 and aligned with an aperture (not shown) in platform 30.
As shown in FIG. 2, the hunter's tripod stand may be broken down and configured in a storage or transport position. Detachable legs 52, 62 are located above permanently attached leg 42, so foot rests 54a, 54b of second leg 52 and foot rests 64a, 64b of third leg 62 are substantially parallel and aligned with foot rests 44a, 44b of first leg 42.
As shown in FIG. 1, second leg 52 includes an upper aperture 58a and a lower aperture 58b that are sized to accept upper storage rod 72 and lower storage rod 74, respectively. Third leg 62 includes an upper aperture 68a and a lower aperture 68b that are sized to accept upper storage rod 72 and lower storage rod 74, respectively. The distances between the apertures in the second leg and the third leg, respectively, are substantially the same as the distance between the storage rods.
According to the preferred embodiment, the distance from an end of the second leg to the upper aperture may be staggered a predetermined distance from the distance from an end of the first leg to the upper storage rod. Likewise, the distance from an end of the third leg to the upper aperture may be staggered a predetermined distance from the distance from an end of the second leg to the upper aperture. This staggered arrangement advantageously provides a clearance of varying distances between platform 30 and the ends of detachable legs 52, 62.
According to the preferred embodiment, the hunter's tripod may be sized as a 4', 5', 6', 7' or 8' stand and may weigh 20-40 lbs. The height of the stand is defined as the distance from the ground or supporting surface to platform 30. For example, each leg of the 4' stand will be slightly greater than four feet in length in view of the angular orientation of each leg.
The plastic chair may weigh approximately 4-5 lbs and the support base may weigh approximately 16-35 lbs. A steel 3/4" to 1" chair bolt having a coarse thread may be welded to a 1/4" steel chair base. A 3/4" to 1" platform nut 32 having a complementary coarse thread may be welded to a 1/4" steel platform 30. The use of a nut and bolt arrangement to rotatably connect the chair to the support base results in a noiseless or substantially noiseless operation of the device.
Many prior art stands use a bearing connection between the chair and support base. A bearing connection is disadvantageous as the rotation of the individual balls or tapered bearings frequently result in noise or sound that is perceptible to the animals or game being hunted. In contrast, the simple, threaded connection of the instant invention provides a noiseless or substantially noiseless connection, which does not audibly alert the game to the hunter's location.
It is contemplated that the 4' embodiment of the hunter's tripod stand may have one or two rungs 48 and the legs may form an angle of from about 62.degree. to about 64.degree. with the horizontal plane defined by platform 30. In other words, the legs may form an angle from about 26.degree. to about 28.degree. with respect to a vertical axis perpendicular to platform 30.
The 5' embodiment of the hunter's tripod stand may have two or three rungs 48 and the legs may form an angle of from about 64.degree. to about 66.degree. with the horizontal plane defined by platform 30. In essence, the legs in conjunction with a vertical axis perpendicular to platform 30 may form an angle from about 24.degree. to about 26.degree..
The 6' embodiment of the hunter's tripod stand may have three or four rungs 48 and the legs may form an angle of about 66.degree. to about 68.degree. with the horizontal plane defined by platform 30. The legs may define an angle from about 22.degree. to about 24.degree. with a vertical axis perpendicular to platform 30.
The 7' embodiment of the hunter's tripod stand may have three or four rungs 48 and the legs may form an angle of from about 68.degree. to about 70.degree. with the horizontal plane defined by platform 30. In other words, the legs and a vertical axis perpendicular to platform 30 may define an angle from about 20.degree. to about 22.degree..
The 8' embodiment of the hunter's tripod stand may have four rungs 48 and the legs may form an angle of from about 70.degree. to about 72.degree. with the horizontal plane defined by platform 30. The legs and a vertical axis perpendicular to platform 30 may define an angle from about 18.degree. to about 20.degree.. Of course, the angle defined by the legs and the number of rungs may be varied to fit the preferences of the user. The above described number of rungs and angular orientations are in accordance with the preferred embodiments of the invention.
It is also contemplated to use aluminum or another high strength low weight material for the support base. With aluminum, an alternative bracing mechanism such as steel rods along the length of each leg may be used to strengthen the support base.
It is to be understood that the present invention is not limited to the preferred embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
