Description

CONVERTIBLE OBSERVATION STAND AND TRANSPORT CARTPRIORITY STATEMENT

[0001] The present application claims the benefit of priority to U.S. provisional patent application 63 / 672,402, titled “CONVERTIBLE HUNTING STAND AND GAME CART”, filed uly 17, 2024, the disclosure of which is incorporated by reference herein in its entirety.FIELD

[0002] The present disclosure is related to observation stands, and more particularly, to hunting stands, hunting blinds, or portable observation towers.BACKGROUND

[0003] Outdoors enthusiasts, hunters, and observers (users) may utilize hunting or observation stands or blinds for obtaining a higher elevation and improved vantage point relative to the subject of their observation. The higher elevation from the ground and the improved vantage point may facilitate a user to view over brush and shrubbery, to provide an increased distance and field of view, and reduce a chance of being seen by hunted game or other subjects of observation.

[0004] Elevated platforms may include freestanding elevated platforms, tripods, tree stands, climbing stands, ladder stands, hanging stands, or box stands. The various types of stands provide advantages and disadvantages. For instance, some stands require a tree or the like for mounting the platform (e.g., a tree stand, ladder stand, hanging stand). While such stands may be portable, they can be cumbersome to transport, install, and teardown. Additionally, such stands may require an appropriate natural structure, such as a tree, which may undesirably limit where and how such stands can be employed.

[0005] Furthermore, portable stands may attempt to improve portability but disadvantageously result in lower heights and user elevation, lower weight limit of the user, or reduced structural rigidity that may result in real or perceived flimsiness of the stand by the user.

[0006] Still some stands are substantially permanent structures fabricated and generally unmoved once fabricated (e.g., box stand). While such stands may avoid issues of cumbersome transportation and temporary installation, the permanency of the structure can be disadvantageous for allowing changes in vantage point and position.

[0007] Additionally, for hunters, hunted game may further require transporting game from the field. The burden of transporting game may further be compounded by the use of a portable stand.

[0008] As such, an improved hunting stand addressing one or more of the aforementioned issues would be beneficial and advantageous. Additionally, a portable hunting stand and game cart addressing one or more of the aforementioned issues would be beneficial and advantageous.BRIEF DESCRIPTION

[0009] Aspects and advantages of the present disclosure will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.

[0010] An aspect of the present disclosure is directed to an observation stand. A frame assembly includes a first frame body pivotably attached to a second frame body. A first pivot member attaches the second frame body to the first frame body in selectively pivotable arrangement between a substantially co-directional position to an angled relationship position. The first frame body extends along a vertical direction greater than the second frame body. A lower frame is pivotably attached to the first frame body. A first support member extends from the lower frame to the first frame body. A second support member extends from the first frame body to the second frame body. The first frame body includes a crossbar forming a step configured to receive a user.

[0011] An aspect of the present disclosure is directed to a convertible observation stand and cart. A first base frame body and a second base frame body are attached to one another at a first pivot member such that the first and second frame bodies are selectively extendable into an A-frame relationship. An extension portion is attached to the first base frame body at a second pivot member such that the extension portionis rotatable from a substantially parallel position to a co-directionally extended position from the first base frame body. The extended position forms a Y-frame relationship of the first base frame body, the second base frame body, and the extension portion. A lower frame is pivotably attached to the extension portion. A first support member is pivotably attached to the lower frame and permitted to rotate to extend from the lower frame and couple to the first base frame body. An upper frame pivotably is attached to the extension portion. The lower frame and the upper frame are rotatable to form an upper portion assembly forming an elevated platform. A second support member is pivotably attached to the extension portion and permitted to rotate to extend from the extension portion and couple to the second base frame body.

The crossbar 23 may form one or more steps configured to receive a user, such as described in regard to crossbar 13, to ingress and egress through opening 30 to an observation platform. Crossbar 23 may additionally, or alternatively, provide structural support and rigidity to an upper portion assembly 55 at which the user is situated in the elevated platform.

[0053] A second support member 24 extends from the first frame body to the second base frame body 14. In various embodiments, the second support member 24 extends from proximate the lower frame 20. In some embodiments, the second support member 24 extends from the extension portion 18 to the second base frame body 14. In various embodiments, the second support member 24 is pivotably attached to the extension portion 18, such as at pivot point interface 25. The pivot point interface 25 may be positioned proximate to the lower frame 20, such as proximate to pivot point interface 19. The second support member 24 may extend substantially vertically from the pivot point interface 19 toward the second base frame body 14, or a crossbar 15 thereof.

[0054] In some embodiments, the second support member 24 includes a crossbar 27 extending between vertically extending members (in the observation stand position). The crossbar 27 may provide a single user interface connecting vertically extending members such that a user may articulate the crossbar 27 to simultaneously move the second support member(s) 27 in unison, such as further described herein.

[0055] The second support member 24, the second base frame body 14, or the crossbar 15 thereof, may separately, or in combination, include a stop member configured to receive and affix the second support member 24 to the second base frame body 14, or crossbar 15 thereof. The stop member may include a bracket, an opening to receive a pin therethrough, or a detent wall configured to inhibit movement of the second support member 24 from the second base frame body 14 or crossbar 15 thereof.

[0056] In various embodiments, the second support member 24 is pivotably attached to the extension portion 18 of the first frame body. For instance, the second support member 24 is pivotably attached to the extension portion 18 and permits vertically downward orientation of the second support member 24. Pivoting or rotatable attachment of the second support member 24 to the extension portion 18 may permit the extension portion 18 to orient vertically downward as the user rotates the extension portion 18 up to a vertical position (e.g., observation stand position). For instance, rotation of the extension portion 18 to the observation stand position may form substantially an inverted Y-frame relationship of the base frame bodies 12, 14 and the extension portion 18.

[0057] In various embodiments, a lock mechanism or attachment interface 141 selectively affixes the second support member 24 to the second base frame body 14.

[0058] In still various embodiments, a lock mechanism or attachment interface 142 selectively affixes the first support member 22 to the first base frame body 12. For instance, the lock mechanism or attachment interface 142 selectively affixes the first support member 22 to the first base frame portion 12.

[0059] In some embodiments, a seat platform 36 is attached to the extension portion 18. The seat platform 36 may be pivotably attached to the extension portion 18, such as at a pivot point interface 37 (Figs. 19-20). The seat platform 36 may include a cushion, a mesh material, netting, or bench, or other appropriate seat or seating material.

[0060] An upper frame 38 is pivotally attached to the extension portion 18. A pivot mechanism 40 couples the upper frame 38 to the extension portion 18. Theupper frame 38 is pivotable from a first side 42 of the extension portion 18 to a second side 44 of the extension portion 18. For instance, upper frame 38 is coupled via pivot mechanism 40 to the extension portion 18 to permit rotation of the upper frame 38 from proximate the first side 42 (e.g., in a stacked position) to proximate the second side 44 (e.g., in an observation stand position). In some embodiments, upper frame 38 is coupled via pivot mechanism 40 to the extension portion 18 to permit rotation of the upper frame 38 up to 360 degrees.

[0061] In some embodiments, a third support member may extend from the upper frame 38 to the extension portion 18. For instance, the third support member may be pivotably attached to the upper frame 38, such as may permit rotation of the third support member as the upper frame 38 is rotated. Third support member may couple to the extension portion 18 and provide support to the upper frame 38.

[0062] In various embodiments, the upper frame 38 forms a greater perimeter dimension than a perimeter dimension of the lower frame 20. For instance, an area within the upper frame 38 is greater than an area within the lower frame 20. The greater perimeter dimension or area may facilitate stacking the lower frame 20 relative to the upper frame 38 when converting between the transportation cart position to the observation stand position.

[0063] In some embodiments, a cover 48 is selectively coupled around the upper frame 38. For instance, a cover frame 50 may extend from the upper frame 38 substantially along a vertical direction. Cover 48 may provide a housing around an observation area extending vertically from the lower frame 20. In some embodiments, the extension portion 18 extends along the vertical direction greater than a pivot point interface 40 to the upper frame 38 to the extension portion 18. In some embodiments as described further herein, the attachment interface 51 is positioned at a distal end of the extension portion 18, such as vertically above the pivot point interface 40.

[0064] In some embodiments, the greater perimeter dimension or area of the upper frame 38 may facilitate coupling the cover 48 to the assembly 20 without requiring fasteners (e.g., zippers, buttons, straps, ties, pins, etc.). Additionally, or alternatively, cover 48 may include a greater upper perimeter or area (e.g. relative to the upper frame 38) relative to a lower perimeter or area (e.g., relative to the lower frame 20).

[0065] In various embodiments, the second base frame body 14 includes a transport member 120. Transport member 120 may include a wheel or other device configured to facilitate movement across the ground. For instance, transport member 120 may include a track, a slide or ski, a plurality of wheels, etc. In various embodiments, the transport member 120 is selectively detachable from the second base frame body 14 (e.g., assembly 100 depicted without transport member in Fig. 4). Transport member 120 may include a crossbar 124 (Figs. 2-3) and mount member 128 from which a ground contact member 126 (e.g., a wheel, track, ski, slide, etc.) attaches. The transport member 120 may form a subassembly separable, in whole or in part, from the second base frame body 14. An attachment interface 129 (Fig. 4) between the transport member 120 and the second base frame body 14 may include openings and pins, mechanical fasteners, clamps, brackets and openings, or other desired selective fastening mechanism.

[0066] As further described herein, materials for cover 48 may facilitate coupling and attachment to the cover frame 50 and lower frame 20 without requiring fasteners. In various embodiments, the cover 48 is formed from an elastic material permitting the cover 48 to wrap around the cover frame 50 and lower frame 20 without requiring fasteners to secure into position. However, cover 48 may further include straps, buttons, pins, hooks, or other attachment mechanisms to further secure the cover 48 to the assembly 100. While various embodiments depicted and described herein may be utilized with assembly 100, it should be appreciated that embodiments of the cover 48 may provide such benefits without requiring structures or geometries of assembly 100.

[0067] In various embodiments, cover 48 is formed from a polymer material. In some embodiments, the cover 48 is formed from a woven polyethylene (PE) material. The woven PE material may include multi-directional weaves, such as may correspond to lateral, transverse, and / or vertical directions for fitting the cover 48 around the cover frame 50, the upper frame 38, and / or lower frame 20. The PE material may include high density PE, low density PE, or combinations thereof. In some embodiments, the cover 48 may include a high density PE weave coated with low density PE, such as may provide multi -directional stretch, resistance to breakage, and water resistance.

[0068] In still some embodiments, the cover is formed from other materials, such as may include other polymer materials, or combinations thereof.

[0069] In various embodiments, straps, hooks, leashes, cables, stops, walls, detents, etc. may be utilized to limit an extension, articulation, transition, or displacement of two or more components from one another. In some embodiments, a cable 39 connects to base frame bodies 12, 14 to limit extension from one another when forming the A-frame. Additionally, or alternatively, a wall may be utilized to limit rotation of the extension portion to form the inverted Y-frame. For instance, a strap may be utilized to limit rotation or other displacement of components when in the erect observation stand position, in one or more stacked positions, or in the transportation cart position.

[0070] A method for constructing an elevated observation stand is provided. The method includes extending a base portion of a first frame body and a second frame body into an A-frame relationship by pivoting one or both of the frame bodies from one another such that ground interfacing portions are separated from one another at the ground; rotating a upper frame at an extension portion of the first frame body from a stacked position to the extension portion to an unstacked position; rotating the extension portion of the first frame body from a stacked position to the base portion to an extended position; rotating a lower frame from a stacked position to the extension portion to an erect position, wherein rotating the lower frame rotates a first support member to contact the base portion of the first frame body; and extending a third support member from the upper frame to contact the extension portion of the first frame body.

[0071] In various embodiments, rotating the extension portion of the first frame body from the stacked position to the base portion to the extended position rotates the upper frame from proximate to a first side of the extension portion to proximate to a second side of the extension portion;

[0072] In still various embodiments, rotating the extension portion of the first frame body from the stacked position to the base portion to the extended position rotates a second support member to contact the second frame body.

[0073] In still yet various embodiments, the method includes rotating a seat platform to an erect position.

[0074] Steps of the method can be performed in reverse or in other orders to deconstruct an elevated observation stand to a transportation cart.

[0075] Additional aspects of the disclosure are provided in the appended figures. Various figures depict stacked positions, transportation cart positions, observation stand positions, and one or more transitions therebetween.

[0076] Components depicted in the figures rotate, pivot, or translate such as depicted at one or more figures, or across one or more figures, or described herein.

[0077] Various components may stack to substantially parallel or co-directional overlapping positions, or within 20 degrees of parallel, or within 15 degrees of parallel, or within 10 degrees of parallel, or within 5 degrees of parallel. In various instances, rotating components described herein may rotate up to 360 degrees, or up to 330 degrees, or up to 300 degrees, or up to 270 degrees, or up to 180 degrees, or within approximately 5 degrees of one or more stated angles, or within approximately 10 degrees of one or more stated angles, or within approximately 15 degrees thereof, or within approximately 20 degrees of one or more stated angles.

[0079] Referring to Figs. 5-6, exemplary embodiments of a method for transportation, construction, and operation of the assembly 100 may include a user towing the assembly 100 to a desired location. The location may include a field, wooded area, parking lot, beach, indoor facility, or other location at which an elevated observation stand may be desired. In Fig. 5, an upper portion assembly 55 forming an observation stand, hunting blind, or enclosure, is depicted in an assembled state in the transportation cart position. In Fig. 6, a fully disassembled state of the assembly 100 in the transportation cart position is provided. A vehicle 200, such as, but not limited to, an all-terrain vehicle, truck, buggy, etc., may be utilized to carry or tow the assembly 100. However, it should be appreciated that, in various embodiments, a usermay manually pull or tow the assembly 100 utilizing the transport member 120 attached to the second base frame body 14.

[0080] In some embodiments, the assembly 100 may be transported on a truck bed, trailer, or other moveable platform, with the transport member 120 attached or detached as may be appropriate. The assembly 100 may further be converted from the transportation cart position (such as depicted in Figs. 6-7) to the observation stand position while on the ground, on the truck bed, on the trailer, or on another stationary or moveable platform.

[0081] Referring to Fig. 7, a depiction of the assembly 100 in the transportation cart position and in a resting state (e.g., removed from the vehicle 200) is provided. The user may further orient the assembly 100 for a desired forward orientation. In various embodiments, the user positions a first end portion 91 of the first base frame body 12 in a direction corresponding primarily toward where a user desires to view. The direction may correspond to a forward orientation and + / - approximately 90 degrees. The first end portion 91 of the assembly 100 includes a portion of components extending from the transport member 120 shorter in a first direction 93 than a portion of components extending from the transport member 120 in a second direction 94 opposite of the first direction 93. The user may pick up a second end portion 92 opposite of the first end portion 91 and tilt the assembly 100 to place the first end portion 91 onto the ground to pivot the base frame bodies 12, 14 away from one another into the A-frame position, such as depicted in Fig. 8.

[0082] In some embodiments, the user tilts the assembly 100 such that the first end portion 91 of the second base frame body 14 touches the ground. Pivot the assembly from the ground such that the second base frame body 14 is permitted to pivot from the first base frame body 12 to form the A-frame in a resting position on the ground, such as depicted in Fig. 8.

Straps may be utilized to wrap around portions of the assembly 100, such as one or more of base frame bodies 12, 14, to secure transported items thereto.

[0084] Referring to Figs. 5-6, in various embodiments, separable portions of the assembly 100 may be positioned onto the bed 150 when transporting the assembly 100 to the desired location. Referring to Fig. 6, the cover frame 50, in a disassembled state, may rest atop the bed 150, or furthermore secured thereto. In still various embodiments, the cover 48, in a disassembled state (e.g., unwrapped from cover frame 50), may be secured to the bed 150 and transported to the desired location. Separable portions of the assembly 100, such as the cover frame 50 and cover 48, or transported items, or both, may be removed from the bed 150 after the assembly 100 is moved to the desired location.

[0085] Referring now to Fig. 8, an exemplary embodiment of the assembly 100 in the A-frame position is depicted. In an embodiment of a method for construction of the assembly 100, the method includes rotating, from the A-frame position, the upper portion assembly 55 upward from the first base frame body 12 of the A-frame, such as depicted along direction 151 in Figs. 8-9. The upper portion assembly 55 includes the lower frame 20 pivotable toward the ground from the extension portion 18, such as depicted along direction 152 in Fig. 9. The upper portion assembly 55 includes the upper frame 38 pivotable upward from the extension portion 18, such as depicted along direction 153 in Figs. 9-10.

[0086] Referring now to Fig. 9, in various embodiments, the lower frame 20 is rotated until the lower frame 20 rests onto the first base frame body 12 of the A- frame. In an exemplary embodiment, the lower frame 20 includes an attachment interface 122 forming a bracket, hole and pin, or clamp releasably attachable to the first base frame body 12, or crossbar 13 thereof. In some embodiments, the lower frame 20 rotates such that the lower frame 20 is substantially pushing vertically downward onto the crossbar 13 of the first base frame body 12. The attachment interface 122 may form a structure, such as a wall, that prevents further rotational movement beyond the crossbar 13. For instance, the attachment interface 122 may form a detent wall inhibiting rotation along direction 152 (or an opposite direction of 152). In some embodiments, the attachment interface 122 is coupled to a forward member portion 123 (Fig. 4, Fig. 9, and Fig. 11) of the lower frame 20. Attaching the lower frame 20, such as the forward member portion 123, to the crossbar 13 may support the upper portion assembly 55 in an intermediate stationary position, such asdepicted in Fig. 9-10. The intermediate stationary position may facilitate the user to perform further translations of components such as further described herein.

[0087] Referring now to Figs. 9-12, in various embodiments, the upper frame 38 is pivotably attached to the extension portion 18 (e.g., at pivot point interface 40) and permitted to rotate approximately 270 degrees, such as depicted along direction 153. In various embodiments, the upper frame 38 is rotatable from a first side of the extension portion 18 to a second side of the extension portion 18. In a rotated position, the upper frame 38 may be oriented substantially in a vertically downward position, such as depicted in Fig. 12. In some embodiments, a distal end of the upper frame 38 relative to the pivot point interface 40 at the extension portion 18, rotates from a first position proximate to the pivot point interface 19 of the lower frame 20 from the extension portion 18 to a second position distal from the pivot point interface 19. In various embodiments, the distal end of the upper frame 38 includes a forward member portion 138 (Fig. 4, Fig. 10). In still some embodiments, the upper frame 38 is rotatable from the pivot point interface 40 such that the upper frame 38 rotates from a first position substantially parallel or overlapping to the extension portion 18 (e.g., corresponding to the transportation cart position) to a second position oblique or perpendicular to the extension portion 18 (e.g., corresponding to the observation stand position).

[0088] Referring to Figs. 10-12, in various embodiments, a distal end of the second support member 24 relative to the pivot point interface 25 rotates from a first position more distal from the second base frame body 14 than the first base frame body 12 (e.g., depicted in Fig. 10) to a second position more proximate to the second base frame body 14 than the first base frame body 12 (e.g., depicted in Fig. 12). Rotation of the second support member 24 along the pivot point interface 25 from the first position to the second position may follow substantially along direction 154. In various embodiments, the distal end of the second support member 24 includes the crossbar 27 positioned distal from the pivot point interface 25.

[0089] In still some embodiments, a distal end of the second support member 24 rotates from a first position proximate to an attachment interface 51 (Fig. 13) of the cover frame 50 to the upper frame 38 to a second position distal from the attachment interface 51 of the cover frame 50 to the upper frame 38.

[0090] Referring to Fig. 12, in various embodiments, rotating the second support member 24 to the second position positions the second support member 24 extending substantially parallel to the extension portion 18. In some embodiments, the second support member 24 is positioned adjacent to the extension portion 18 such that the second support member 24 is substantially parallel to the extension portion 18 and vertically above the extension portion 18 such that a downward force (depicted schematically via arrow 155 as substantially downward toward the ground) applied to the distal end of the second support member 24, such as at the crossbar 27, transmits from the support member 24, or crossbar 27 thereof, onto the extension portion 18, such as further depicted and described herein.

[0091] In various embodiments, the second support member 24 and pivot point interface 25 are configured to permit rotation of the second support member 24 approximately 180 degrees, such as described and depicted along direction 154 in Figs. 10-12. In still various embodiments, the second support member 24 is configured relative to the extension portion 18 such that the extension portion 18 may provide a detent along the rotational direction 154 such that further rotation of the second support member 24 further rotates the extension portion 18, such as further described herein.

[0092] Referring back to Fig. 13, and further to Figs. 14-15, in some embodiments, the cover frame 50 may be attached to the extension portion 18 at the attachment interface 51. The cover frame 50 may additionally, or alternatively, be attached to an attachment interface 53 at the upper frame 38. The attachment interfaces 51, 53 may include an opening configured to receive a frame member 54. The frame member 54 may be rotatable, pivotable, or separable, such as may form stakes configured to receive the cover 48 or provide an outer frame around which the cover 48 wraps. In various embodiments, the cover 48 may be attached, wrapped, or otherwise positioned around the cover frame 50 while the upper portion assembly 55 is in a lowered, intermediate position (e.g. depicted in Figs. 13-15).

[0093] Referring now to Figs. 16-18, a user applies a downward force to the second support member 24 to rotate (e.g., along direction 156) the upper portion assembly 55 to an upright vertical position, such as depicted in Fig. 17. In some embodiments, applying the downward force 155 (Fig. 12) includes a pulling actiontoward the ground onto the second support member 24 from the distal end, such as at the crossbar 27. The distal end, when pulled substantially downward (e.g., corresponding to direction 156), pushes onto the extension portion 18 such as to force the extension 18 portion to pivot at the second pivot member 26. In various embodiments, rotation of the extension portion 18 at the second pivot member 26 may be approximately 90 degrees or more from an initial position (e.g., depicted in Fig. 12). The second pivot member 26 at the first base frame body 12 of the A-frame to the extension portion 18 includes a stop member 29 (e.g., depicted in further detail in Fig. 8) that limits movement of the extension portion 18 to a desired position relative to the first base frame body 12. In various embodiments, the stop member limits movement of the extension portion 18 such that the extension 18 portion, when in the vertical observation stand position (e.g., depicted in Fig. 17), extends co-directional to the first base frame body 12. The A-frame, with the extension portion 18 in the vertical position extending co-directional to the first base frame body 12 of the A- frame, may form an inverted Y-frame. In some embodiments, the second support member 24 is permitted to freely hang from the extension portion 18 in the vertical position.

[0094] In still some embodiments, the second support member 24 may be fastened to the second base frame body 14, such as may provide a structural member extending from the upper portion assembly 55 to the second base frame body 14 of the A-frame. As such, forces applied rearward from the upper portion assembly 55 may be stabilized, at least in part, through the second support member 24 connecting to the second base frame body 14 of the A-frame.

[0095] In some embodiments, the second base frame body 14 and second support member 24, or crossbar 27 thereof, includes an attachment interface 141 configured to affix the second support member 24 to the second base frame body 14. The attachment interface 141 may include a bracket having an opening through which a member is extendable. In various embodiments, the bracket may be integrated into, or form a portion of, the second support member 24 or the second base frame body 14. The second support member 24 or the second base frame body 14 may include an opening into which the other structure is extendable, such as may affix the structures together.

[0096] In still various embodiments, rotatability of the extension portion 18 relative to the first base frame body 12 and rotatability of the second support member 24 relative to the extension portion 18 permits a substantially upward and downward vertical movement (e.g., depicted schematically via arrows 157 in Fig. 18) of the second support member 24. The upward and downward vertical movement along direction 157 may permit the second support member 24, or crossbar 27 thereof, to rotate along direction 156 and displace over or around the attachment interface 141. In some embodiments, the attachment interface 141 extends from one second base frame body 14 to another. Upward and downward vertical movement of the second support member 24 may permit the second support member 24, or crossbar 27 thereof, to rotate past a plane between the second base frame bodies 14, such as a transition between depictions in Fig. 16 to Fig. 17. Upward and downward movement of the second support member 24 may additionally, or alternatively, permit the second support member 24, or crossbar 27 thereof, to seat vertically downward into the attachment interface 141.

[0097] Referring now to Figs. 18-21, in various embodiments, the upper portion assembly 55 includes the lower frame 20 rotatably attached to the extension portion 18. The lower frame 20 may form a footrest or base vertically below the seat platform 36 connected to the extension portion 18 above the lower frame 20. In some embodiments, the first support member 22 connects from the lower frame 20 to the first base frame body 12 of the A-frame. The first support member 22 may permit forces applied to the lower frame 20 (e.g., a person standing on the lower frame 20 or seated at the seat platform 36) to stabilize from connection to the first base frame body 12 of the A-frame. In some embodiments, the first support member 22 extends from the lower frame 20 to the crossbar 23 at the first base frame body 12 of the A- frame. The first support member 22 may include the crossbar 23, such that a ladder is formed from one or more crossbars 13 at the first base frame body 12 of the A-frame and extending onto one or more crossbars 23 at the first support member 22.

[0098] In various embodiments, the first support member 22 and the first base frame body 12 of the A-frame may together include an attachment interface 142 (Fig. 21) at which the first support member 22 connects to the first base frame body 12 ofthe A-frame. In some embodiments, the attachment interface 142 is configured such as described in regard to attachment interface 141.

[0099] In some embodiments, the cover 48 attached to the cover frame 50 further extends downward to attach onto the lower frame 20. For instance, referring to Fig. 17, the cover 48 may extend downward such as may around and obscure the lower frame 20 from an exterior.

[0100] In an exemplary method for operation, the upper portion assembly 55 forms an elevated platform 127 (e.g., depicted in Fig. 20), such as an observation deck, nest, hunting blind, or tower. A user may ascend to and descend from the upper portion assembly 55 by climbing the crossbars 13, 23 at the first base frame body 12 of the A-frame and the first support member. The lower frame 20 may form a substantially U-shape, C-shape, or hoop extending forward and wrapping around, such as may form the opening 30 through which the user may ingress to and egress from the upper portion assembly 55. The seat platform 36 may extend from the extension portion 18. In various embodiments, the seat platform 36 may include a pivot point interface 37 (Fig. 20) from the extension portion 18, such as may provide a seating area within a volume surrounded by the lower frame 20 and the upper frame 38 (e.g., to the front and sides relative to a user sitting at the seat), and with the extension portion 18 behind the user, or one or more crossbars 17 of the extension portion 18. The cover frame 50 may further be attached to the upper frame 38 and extension portion 50 and extend the volume circumscribing the elevated platform and seating area.

[0101] Steps and depictions of an exemplary method for construction may be performed substantially in reverse as a method for deconstruction. For instance, directions depicted herein may be reversed, and various steps may be taken in reverse serial operation, to convert the elevated observation stand to the transportation cart.

[0102] In an embodiment of operation, a user may remove the transport member 120 as a method for obstructing undesired relocation or appropriation of the assembly 100. For instance, weight of the A-frame or Y-frame may be such that movement and relocation of the assembly 100 is substantially inhibited by removing the transport member 120. Such operation may permit a user to locate and setup the assembly 100 in the elevated observation stand position at a desired location without requiring, as amatter of security, conversion back to the transportation cart and removal. For instance, embodiments of the A-frame, Y-frame, or upper portion assembly may be constructed of metal, metal alloys, or metal composites. A corresponding weight may be approximately 140 pounds or greater, which may inhibit movement of the assembly 100 without the transport member 120 attached.

[0103] It should be appreciated that embodiments of the assembly 100 may be formed of plastic, carbon fiber, metal, metal alloy, wood, composite, or other materials, or combinations thereof. In still some embodiments, the transport member 120, or portions thereof, may be integrally formed with or connected to the second base frame body 14.

[0104] Embodiments of lock mechanisms or attachment interfaces described herein may include a pins, rods, mechanical fasteners, bolts, tie rods, latches, bracket, detent walls, or other mechanisms configured to selectively affix respective members together in accordance with descriptions, movements, translations, or rotations depicted and described herein. Various interfaces may include pins configured to affix members together in the transportation cart position, the observation stand position, or one or more intermediate positions therebetween.

[0105] Embodiments of pivot members, pivot point interfaces, or pivoting structures or configurations may include hinges, pivot joints, pin and opening, or other structures appropriate for rotating, translating, or articulating members such as described and depicted herein.

[0106] In some embodiments, one or more crossbars may provide a tie-down point to a grounding structure. For instance, referring to Fig. 4, an upper crossbar 15 may be utilized to hook, tie down, or affix a rope or strap to a grounding structure, such as, but not limited to, a tie-down location, eyebolt, hook, stake, etc. in the ground, at a truck bed, at a trailer, at a tree or natural structure, or other appropriate grounding structure.

[0107] Embodiments of the assembly 100 provide a portable convertible transportation cart and elevated observation stand. Embodiments provided herein may form a convertible portable observation stand, hunting stand, hunting blind, or surveillance tower, such as may provide a user with an elevated vantage point and field of view. Embodiments provided herein may additionally provide a transportationcart, such as may form a trailer or bed utilizable for transporting hunted game, equipment, gear, portions of the assembly 100, or other materials and apparatuses. Conversion to and from the transportation cart position may facilitate locating and relocating, temporary placement, or semi -permanent placement, of an elevated stand.
