Accordingly, the apparatus components have been represented, where appropriate, by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. Further, like numerals in the description and drawings represent like elements.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “lateral,” “rear,” “front,” “vertical,” “horizontal,” “upward,” “downward” and derivatives thereof shall relate to the disclosure as oriented in FIG. 1. Unless stated otherwise, the term “front” shall refer to the surface of the element closer to an intended viewer, and the term “rear” shall refer to the surface of the element further from the intended viewer. Unless stated otherwise, the term “forward” shall refer to toward the intended viewer and/or closer to the intended viewer based on the context. For example, the phrase “extending forward” shall be interpreted as extending toward the intended viewer, while a first element being “forward of” a second element shall refer to the first element being closer than the second element to the intended viewer. Unless stated otherwise, the term “rearward” shall refer to away from the intended viewer and/or further from the intended viewer based on the context. For example, the phrase “extending rearward” shall be interpreted as extending away from the intended viewer, while a first element being “rearward of” a second element shall refer to the first element being further than the second element from the intended viewer. Unless stated otherwise, the term “lateral” and derivatives thereof shall refer to left-right directions. However, it is to be understood that the disclosure may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
As used herein, the term “and/or,” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
For purposes of this disclosure, the term “coupled” (in all of its forms: couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and/or any additional intermediate members. Such joining may include members being integrally formed as a single unitary body with one another (i.e., integrally coupled) or may refer to joining of two components. Such joining may be permanent in nature, or may be removable or releasable in nature, unless otherwise stated.
As used herein the terms “the,” “a,” or “an,” mean “at least one,” and should not be limited to “only one” unless explicitly indicated to the contrary.

Referring now to FIGS. 1-6, the climbing stick 10 includes the first step 12, the second step 14, and the post 15 that extends between the first and second steps 12, 14. In the embodiment illustrated in FIG. 1, the first step 12 of the climbing stick 10 is a bottom step 18, and the second step 14 is a top step 20 that is positioned upward of the bottom step 18. In various implementations, the first step 12 may be the top step 20 and the second step 14 may be the bottom step 18 positioned downward of the top step 20. The post 15 of the climbing stick 10 extends from the first step 12 to the second step 14 along the length of the post 15.
The post 15 can include a plurality of walls 22 that protrude outward from at least one floor portion 24 of the post 15 and, further, extend in a lengthwise direction L of the post 15 (i.e., along the length of the post 15). The plurality of walls 22 and the at least one floor portion 24 of the post 15 may cooperate to define at least one channel 26 that extends along the length of the post 15. For example, as illustrated in FIGS. 1-3, the post 15 includes a first outer wall 28 that extends in the lengthwise direction L of the post 15, a second outer wall 30 that extends in the lengthwise direction L of the post 15, and an inner wall 32 that extends in the lengthwise direction L of the post 15. The inner wall 32 is positioned between the first and second outer walls 28, 30.
In the embodiment illustrated in FIG. 1, a first floor portion 34 extends in the lengthwise direction L of the post 15 and extends between the first outer wall 28 and the inner wall 32. A second floor portion 36 extends in the lengthwise direction L of the post 15 and extends between the second outer wall 30 and the inner wall 32. The first outer wall 28, the inner wall 32, and the first floor portion 34 define a first channel 38 that extends along the lengthwise direction L of the post 15. The second outer wall 30, the inner wall 32, and the second floor portion 36 define a second channel 40 that extends along the lengthwise direction L of the post 15. As illustrated in FIG. 1, the surfaces of the first and second floor portions 34, 36 of the post 15 that define the first and second channels 38, 40, respectively, face forward. Further, the inner wall 32 and the first and second outer walls 28, 30 extend forward from the first and second floor portions 34, 36.
Referring now to FIGS. 4 and 5, in some embodiments, the post 15 includes at least one floor portion 24 that includes a channel-defining surface that faces rearward. For example, as illustrated in FIGS. 4 and 5, the post 15 includes first and second floor portions 34, 36 that face rearward and an inner wall 32 and first and second outer walls 28, 30 that extend rearward from the first and second floor portions 34, 36. As such, first and second channels 38, 40 are defined on the rear side 19 of the post 15. In various embodiments, one or more channels 26 can be defined on the front side 17 of the post 15 and the rear side 19 of the post 15. For example, the post 15 can include first and second floor portions 34, 36, an inner wall 32, and first and second outer walls 28, 30 that cooperate to define first and second channels 38, 40 on both the front and rear sides 17, 19 of the post 15. It is contemplated that one or more channels 38, 40 that are defined by the front and/or rear sides 17, 19 of the post 15 may extend beyond the post 15, such that the one or more channels 38, 40 are additionally defined by portions of the first and/or second steps 12, 14.
Referring now to FIGS. 1-5, the post 15 can define an aperture 42. As illustrated in FIGS. 1-5, the inner wall 32 of the post 15 at least partially defines the aperture 42 that extends through the post 15. In various embodiments, the inner wall 32 wholly defines the aperture 42 that extends through the post 15. The aperture 42 defined by the post 15 may be configured to receive a fastener for attaching a strap to the post 15 of the climbing stick 10 for selectively strapping multiple climbing sticks 10 together for transportation purposes.
Referring now to FIGS. 1-8, the climbing stick 10 can include a cleat 44. In various embodiments, the climbing stick 10 can include a plurality of cleats 44. For example, as illustrated in FIGS. 1-5, the climbing stick 10 includes two cleats 44. The cleat 44 is coupled to the post 15 between the first and second steps 12, 14 of the climbing stick 10. In various embodiments, the cleat 44 is coupled to the post 15 between the front and rear sides 17, 19 of the post 15, as illustrated in FIGS. 2, 3, 5, and 6. The cleat 44 includes a neck 46 that is coupled to the post 15 and extends outward therefrom. The cleat 44 further includes a head 48 that is coupled to the neck 46 distally from the post 15. In various implementations, the head 48 defines a slot 50. In the embodiment illustrated in FIG. 2, the slot 50 is defined on an upper side of the head 48, such that the slot 50 faces generally upward toward the second step 14 (i.e., the top step 20). It is contemplated that the slot 50 may face a variety of directions in various embodiments. In some embodiments, the slot 50 defined by the cleat 44 may have a width of about two millimeters. The slot 50 being about 2 mm wide may snuggly accommodate certain types of rope that may be used to secure the climbing stick 10 to a tree, such as Paracord™. In some implementations, the cleat 44 defines a cleat aperture 52. For example, as illustrated in FIGS. 1-5, the neck 46 of the cleat 44 defines a cleat aperture 52.
Referring now to FIG. 6, in some implementations, the cleat 44 coupled to the post 15 of the climbing stick 10 angles forward and laterally-outboard from the post 15. In various embodiments, the cleat 44 is angled, such that a portion of the cleat 44 is positioned further forward than the forward-most surface of the post 15. For example, as illustrated in FIG. 6, a portion of the cleat 44 that is distal from the post 15 extends forward beyond the forward-most surface of the post 15. In various embodiments, the portion of the neck 46 of the cleat 44 that is proximal to the post 15 may be positioned wholly between the forward-most surface of the post 15 and the rearward-most surface of the post 15.

As illustrated in FIG. 1, the post 15 extends between the first and second steps 12, 14 and is coupled to the first and second steps 12, 14 at corners 54. As illustrated, the corners 54 are generally rounded, which may advantageously influence resin flow and fiber orientation during injection molding of the climbing stick 10, as described further herein. As further illustrated in FIG. 1, the first and second steps 12, 14 extend laterally-outboard from the post 15 to laterally-distal ends 56 of the first and second steps 12, 14, respectively. In other words, as illustrated in FIG. 1, the first step 12 extends outward from the post 15 to the right to a right laterally-distal end 58 of the first step 12, and the first step 12 extends outward from the post 15 to the left to a left laterally-distal end 60 of the first step 12. Further, the second step 14 extends outward from the post 15 to the right to a right laterally-distal end 58 of the second step 14, and the second step 14 extends outward from the post 15 to the left to a left laterally-distal end 60 of the second step 14.
The first and second steps 12, 14 each include an upper stepping surface 62. The upper stepping surface 62 faces upward and is configured to support the foot of a user standing on the first and/or second step 12, 14. As illustrated in FIGS. 1-4, a plurality of traction ridges 64 extend upward from the upper stepping surfaces 62 of the first and second steps 12, 14. The traction ridges 64 extend in a forward-rearward direction and are spaced apart from each other in the lateral direction along the upper stepping surface 62 of each of the first and second steps 12, 14.
As illustrated in FIG. 1, the first step 12 includes a tang 66 that extends downward from the first step 12 away from the second step 14. It is contemplated that the first step 12 may include a plurality of tangs 66 that extend downward from the first step 12. For example, in the embodiment illustrated in FIG. 1, the first step 12 includes two tangs 66 that extend downward from the first step 12. The tang 66 may extend downward at the laterally-distal end 56 of the first step 12, in some embodiments. For example, in the embodiment illustrated in FIG. 1, the two tangs 66 of the first step 12 extend downward from the first step 12 at the left and right laterally-distal ends 60, 58 of the first step 12, respectively.
Referring still to FIG. 1, the second step 14 can include a tang 66 that extends upward from the second step 14 away from the first step 12. The second step 14 can include a plurality of tangs 66 that extend upward from the second step 14. For example, as illustrated in FIG. 1, the second step 14 includes two tangs 66 that extend upward from the second step 14. The tang 66 of the second step 14 can extend upward at the laterally-distal end 56 of the second step 14. For example, as illustrated in FIG. 1, the two tangs 66 of the second step 14 extend upward from the second step 14 at the left and right laterally-distal ends 60, 58 of the second step 14, respectively.
In various implementations, the tang 66 of the second step 14 can extend upward from the upper stepping surface 62 of the second step 14 further than the traction ridges 64 of the second step 14 extend upward from the upper stepping surface 62 of the second step 14. In some embodiments, one or more of the tangs 66 of the first and second steps 12, 14 are laterally aligned with each other. In other words, the tang 66 of the first step 12 and the tang 66 of the second step 14 may be positioned relative to each other such that both tangs 66 fall within a plane extending normal to the lateral direction. In the embodiment illustrated in FIG. 1, the tang 66 positioned at the left laterally-distal end 60 of the first step 12 is laterally aligned with the tang 66 positioned at the left laterally-distal end 60 of the second step 14. Further, the tang 66 of the right laterally-distal end 58 of the first step 12 is laterally aligned with the tang 66 of the right laterally-distal end 58 of the second step 14.
In some embodiments, the first step 12 can include at least one tang 66 that extends upward from the laterally-distal ends 56 of the first step 12.

The present disclosure may provide a variety of advantages. First, forming the climbing stick 10 from a thermoplastic resin via injection molding results in the climbing stick 10 being significantly lighter than similarly sized climbing sticks 10 that are formed of conventional materials, such as metal. Second, despite the reduced weight of the climbing stick 10 enabled by use of the thermoplastic material, the sub-plurality of fibers 16A that are oriented substantially parallel with the length of the post 15 of the climbing stick 10 ensure that the climbing stick 10 has sufficient structural integrity for conventional use. Third, the channels 26 defined by the post 15 contribute to climbing stick weight reduction, influence resin flow and fiber 16 orientation within the post 15, and are configured to receive protrusions 72 of other climbing sticks 10 therein, such that multiple climbing sticks 10 may be slidingly engaged with each other for convenient, compact storage and transportation. Fourth, the cleat 44 angling forward and outboard from the post 15 of the climbing stick 10 may increase the ease with which a user can fasten the climbing stick 10 to a tree by providing additional space between the tree and the rear side of the cleat 44. Fifth, the first and second steps 12, 14 including downward and upward extending tangs 66, respectively, may allow a user to securely coil the tag end of a rope about the first and second steps 12, 14 of the climbing stick 10. Sixth, the step recesses 68 and standoff recesses 86 being separated from each other by the step walls 70 and standoff walls 88, respectively, may advantageously influence the flow of resin and the orientation of fibers 16, 100 within the resin during injection molding of the climbing stick 10 to increase the structural integrity of the climbing stick 10 while reducing the overall weight of the climbing stick 10.
