One piece climbing stick design
View Patent ↗The present invention generally relates to a one-piece climbing sticks for use in climbing trees for hunting or other purposes. The climbing sticks of the invention are characterized by a double step, one-piece design wherein the center support structure and the double steps emanating therefrom are fabricated from a single sheet or piece of aluminum and/or aluminum alloy.
1 . A one piece climbing stick configured to be releasably securable to a tree comprising a center support structure and at least two double steps, wherein a first double step is fabricated proximate to the uppermost section of the center support structure and a second double step is fabricated proximate to the lowermost section of said center support structure, wherein said climbing stick is solid metal and is fabricated from a single sheet of aluminum or aluminum alloy stock and wherein said one-piece climbing stick comprises at least two support bolts mounted to said climbing stick which are configured to securely engage a tree when in use.
2 . The one-piece climbing stick of claim 1 wherein each double step comprises a left and right step each comprising a stepping surface, wherein said double step is in the same plane of and perpendicular to the center support structure.
3 . The one-piece climbing stick of claim 2 wherein the left and right step of said double step is angled from 1 to about 20 degrees upward from the horizontal plane.
4 . The one-piece climbing stick of claim 2 wherein said double steps comprise foot grips molded or cut into the stepping surfaces of said double steps allowing for a non-slip stepping surface for the user when climbing.
5 . The one-piece climbing stick of claim 1 which comprises two support bolts wherein one support bolt is mounted to the left step of the uppermost double step and one support bolt is mounted to the right step of the uppermost double step.
6 . The one-piece climbing stick of claim 5 wherein the length of the support bolts is adjustable and said support bolts are angled outward at an angle of from 1 to 20 degrees from the plane that is perpendicular to the center support structure.
7 . The one-piece stick of claim 5 comprising an additional set of support bolts mounted to the lowermost double steps of said one-piece stick wherein a first support bolt is mounted to the left step of the lowermost double step and a second bolt is mounted to the right step of the lowermost double step.
8 . The one-piece climbing stick of claim 5 comprising at least two receiving ports or holes proximate to the top and/or bottom double steps of the climbing stick, wherein said receiving ports are configured to receive the support bolts of another stick, allowing two or more sticks to be securely nested together.
9 . The one-piece climbing stick of claim 1 which additionally comprises at least one a fastener, wherein said fastener comprises a retaining flange mounted to the center support structure or an attachment anchor that is fabricated as part of the one-piece stick.
10 . The one-piece climbing stick of claim 9 wherein said retaining flange is circular and is secured to the center support structure by a bolt inserted through the center of the retaining flange and through the support structure and secured on the opposite side of said support structure by a fastener or a nut.
11 . The one-piece stick of claim 9 wherein said circular retaining flange and/or attachment anchor are configured to receive a securing belt to securely attach said stick to a tree, wherein said securing belt is selected from a strap, cable, rope or chain.
12 . The one-piece climbing stick of claim 11 wherein said securing belt comprises an adjustable buckle and a pair of straps, cables, ropes or chains, each including a loop at one end, wherein the straps, cables, ropes or chains are placed around a tree and loops placed over the flange or attachment anchors of the to secure the climbing stick to a tree.
13 . The one-piece climbing stick of claim 9 wherein said fastener comprises two attachment anchors fabricated on the left and right sides of said center support structure.
14 . The one-piece climbing stick of claim 1 which is fabricated from solid aluminum or aluminum alloy stock that is milled, machined, laser cut and/or water jetted.
15 . The one-piece climbing stick of claim 1 which additionally comprises a belt fastener disposed on the center support structure of said climbing stick.
16 . The one-piece climbing stick of claim 9 wherein said attachment anchor or retaining flange are fabricated as part of the one-piece design.
17 . The one-piece climbing stick of claim 5 wherein said support bolts are adjustable and can be lengthened or shortened thereby adjusting the distance said one-piece stick is from the tree.
