US 12,527,315 B2 · Tree engaging structure for a treestand or climbing stick

Abstract

A climbing system includes a treestand and a plurality of climbing sticks. The treestand includes a monolithic platform formed from strengthened material. Each of the climbing sticks includes a frame having a plurality of weight-reduction apertures formed therethrough. Tree engaging structures include ramped surfaces to facilitate smooth downward sliding on a tree. Methods of manufacturing a treestand and climbing sticks are also disclosed. The method of manufacturing a treestand includes providing a solid, strengthened piece of material and removing portions of the material to form openings between structural supports. The method of manufacturing a climbing stick includes providing a frame and forming a plurality of weight-reduction apertures therethrough.

A tree engaging structure of a tree climbing stick, said tree engaging structure comprising:

a base configured to be coupled to a frame, said base having a first portion disposed on a first side of a median plane passing through said base and a second portion disposed on an opposite second side of said median plane;
a first limb extending from said first portion of said base away from said median plane, said first limb including a first proximal portion, a first distal portion, and a first intermediate portion disposed between said first proximal portion and said first distal portion;
a second limb extending from said second portion of said base away from said median plane, said second limb including a second proximal portion, a second distal portion, and a second intermediate portion disposed between said second proximal portion and said second distal portion;
a first proximal tooth extending from a front side of said first proximal portion of said first limb, said first proximal tooth having a lateral surface, a medial surface, and an apex;
a second proximal tooth extending from said second proximal portion of said second limb, said second proximal tooth having a lateral surface, a medial surface, and an apex;
a first distal tooth extending from said first distal portion of said first limb, said first distal tooth having a lateral surface, a medial surface, and an apex;
and
a second distal tooth extending from said second distal portion of said second limb, said second distal tooth having a lateral surface, a medial surface, and an apex;
a first intermediate tooth disposed between said first proximal tooth and said first distal tooth, said first intermediate tooth extending from said first intermediate portion of said first limb, said first intermediate tooth having a lateral surface, a medial surface, and an apex;
a second intermediate tooth disposed between said second proximal tooth and said second distal tooth, said second intermediate tooth extending from said second intermediate portion of said second limb, said second intermediate tooth having a lateral surface, a medial surface, and an apex;
a third intermediate tooth disposed between said first intermediate tooth and said first distal tooth, said third intermediate tooth extending from said first intermediate portion of said first limb, said third intermediate tooth having a lateral surface, a medial surface, and an apex;
a fourth intermediate tooth disposed between said second intermediate tooth and said second distal tooth, said fourth intermediate tooth extending from said second intermediate portion of said second limb, said fourth intermediate tooth having a lateral surface, a medial surface, and an apex;
and wherein
a first straight line intersects said apex of said first proximal tooth and said apex of said first intermediate tooth;
a second straight line intersects said apex of said first intermediate tooth and said apex of said third intermediate tooth and passes in front of said apex of said first proximal tooth;
and
said first straight line and said second straight line intersect one another at a non-zero angle.
