DETAILED DESCRIPTION

[0025] Particular aspects and features of the present disclosure are described hereinbelow with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.

[0026] With reference to FIG. 1, a support member provided in accordance with the present disclosure is shown generally identified by reference numeral 100. Support member 100, as detailed below, is configured and dimensioned to removably attach to a mounting member 600 (FIG. 3) for securing support member 100 to a vertically orientated support structure, such as a tree T (FIG. 4). It will be understood that support member 100 may be attached to any suitable mounting member 600 (FIG. 3), 600 (FIGS. 5A-5B), or a plurality of different mounting members, such as for example, 600 (FIGS. 3), and 600 (FIGS. 5A-6) for securing support member 100 to tree T (FIG. 4). It will be further understood that any or all of the components of the support member 100 may be formed of suitable materials, e.g., metals or composites. In some embodiments, it is desirable to minimize the total weight of the support member 100 for ease of carrying and mounting. Accordingly, support member 100 may be partially or entirely formed of a lightweight material, e.g., a carbon fiber composite or lightweight alloy.

[0027] Referring to FIGS. 1-4, as detailed below, support member 100 includes a U-shaped frame 200; a shaft assembly 300 having an outer shaft 310 and an inner shaft 320; and a connector 400. Support member 100, as also detailed below, is configured and dimensioned for use as part of a system in conjunction with a mounting member 600 to engage support member 100 to a tree T.

[0028] U-shaped frame 200 includes a pair of spaced-apart arms 210 interconnected by a crossbar 220. Arms 210 define free ends configured to releasably attach to the side rails of a ladder. Such releasable attachment may be made by way of a male-female engagement, nut and bolt engagement, lock-pin engagement, latching engagement, complementary fitting, or other suitable configuration to releasably attach arms 210 of U-shaped frame 200 to a ladder, for example a ladder of a tree stand S. Crossbar 220 defines a plurality of apertures 222 defined therethrough and arranged in a spaced-apart fashion along crossbar 220.

[0029] Shaft assembly 300 includes an outer shaft 310 and an inner shaft 320 that are telescopically slidably relative to one another along a longitudinal axis of shaft assembly 300. Outer shaft 310, more specifically, defines a fixed end 312, a free end 314, and an inner lumen (not shown) extending longitudinally therethrough that slidably receives inner shaft 320. Fixed end 312 of outer shaft 310 includes a bracket 316 configured to engage outer shaft 310 with crossbar 220 at any one of a plurality of positions, e.g., via engagement of a bolt 317 with bracket 316 and any one of apertures 222 of crossbar 220. Outer shaft 310 further defines an aperture 318 therethrough towards the free end 314 thereof.

[0030] Inner shaft 320 includes a first end (not shown) slidably received within the inner lumen (not shown) of outer shaft 310 and a second free end 322 extending from outer shaft 310. Second end 322 of inner shaft 320 includes a connector 400, e.g., a bracket or other suitable connector, engaged thereto. Inner shaft 320 further includes a plurality of apertures (not shown) defined therethrough and arranged in a longitudinally-spaced relation along the longitudinal axis. Outer and inner shafts 310, 320 are configured to slide relative to one another to align aperture 318 of outer shaft 310 with one of the apertures (not shown) of inner shaft 320 for receipt of an engagement pin 340 therethrough to engage outer and inner shafts 310, 320, respectively, to one another at any one of a plurality of incremental positions.

[0031] Connector 400 is configured to facilitate releasable engagement of support member 100 to a mounting member, e.g., mounting member 600 that, in turn, is configured to engage a vertical support structure, e.g., a tree T. Connector 400 may be configured as a bracket or other suitable connector and includes a retainer 410 configured to releasably engage an engagement member 420. Retainer 410 may include opening 412 for receipt of the engagement member 420 and a locking pin 414 for engaging the engagement member 420 therein. Retainer 410 may further be configured to receive various different engagement members, e.g., engagement member 420 (FIG. 2) and engagement member 420 (FIG. 6) so as to enable releasable engagement of support member 100 with various different mounting members, e.g., mounting member 600 and mounting member 600 (FIGS. 5A-6). As can be appreciated, each engagement member corresponds to one or more different mounting members. Regardless of the particular engagement member or mounting member, locking pin 414 is used to engage the engagement member 420 with retainer 410.

[0032] Engagement member 420 serves as a male connection feature for releasable receipt within the female connection feature of mounting member 600. Mounting member 600 is configured to engage a tree T via teeth 610 and strap 620. More specifically, mounting member 600 is placed against a tree T with teeth 610 oriented towards the tree T. Thereafter, strap 620 is wrapped around the tree T and tightened so as to urge teeth 610 into fixed engagement with the tree T. With mounting member 600 in place, engagement member 420 can be inserted into engagement aperture 630 of mounting member 600 to thereby engage support member 100 with the tree T. With U-shaped frame 200 of support member 100 engaged with a ladder, e.g., of a tree stand S, and connector 400 engaged with mounting member 600, the ladder is secured to the tree T in spaced-apart relation relative thereto (see FIG. 4).

[0033] Turning to FIGS. 5A-6, another mounting member 600 configured and dimensioned for use with support member 100 is shown. Mounting member 600 includes a base 610 and a threaded shank 620. Base 610 serves as a female connection feature for receiving a corresponding engagement member 420 engaged with connector 400 of support member 100 to secure support member 100 to mounting member 600. A more detailed discussion of mounting member 600 can be found in U.S. patent application Ser. No. 14/198,818, filed on Mar. 6, 2014 and entitled Portable Tree Stand System, the entire contents of which is incorporated herein by reference.

[0034] Referring generally to FIGS. 1-6, the above-detailed configuration of support member 100 and mounting members 600, 600 provide a safe, secure system for securing a ladder to a structure. Although detailed herein with respect to a ladder of a tree stand S secured to a tree T, support member 100 and mounting members 600, 600 can be used for safely securing a ladder to various other structures for various other purposes, for example, to a deck, house, or other building for viewing and/or repairing roofs, to a telephone pole for performing work on power lines, etc.

[0035] The above-detailed configuration of support member 100 and mounting members 600, 600 also enable a user to engage multiple mounting members 600, 600 to multiple trees T or other structures such that support member 100 and the ladder may be transported between and releasably engaged with a plurality of trees T or other structures without having to remove the mounting members 600, 600. This configuration minimizes the visibility of the locations of mounting members 600, 600, while still enabling fast, easy, and secure installation of a ladder when needed at that particular location.

[0036] While several aspects of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular aspects. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
