[0081]The arm member is reconfigurable with respect to the mounting bracket from an open position to a closed and locked orientation/position. The open position of the arm member allows a portion of an object to be positioned between an open space between the mounting bracket and the arm member, and be physically supported by at least one of the mounting bracket and the arm member. In the closed and locked position of the arm member, the arm member and the mounting bracket may form an enclosed space that extends about a portion of the object, and the arm member and/or the mounting bracket may physically support the object. In some embodiments, in the closed and locked position of the arm member, the arm member may be selectively locked in the closed position such that the arm member remains in the closed position until the arm member is manually selectively reconfigured into the open position. In some other embodiments, in the closed and locked position of the arm member with a portion of the object positioned within the enclosed space, the arm member may be fixedly locked in the closed position such that the arm member cannot be manually selectively reconfigured into the open position.
[0082]The arm member may be slidable along the elongate track portion of the mounting bracket. For example, the track portion of the mounting bracket may define an elongated slot between opposing rail portions, and the arm member may be slidable along the rail portions and within the slot portion. The track portion may be configured to allow the arm member to rotate into the open position when positioned at a first upper portion of the track portion, and orient and lock the arm member in the closed positioned when positioned at other portions (e.g., lower portions) of the track portion.
[0083]The self-locking/closing device may be used to hang any object to any mounting surface. For example, without limitation, the self-locking device may hang various different objects, such as framed, pictures, mirrors, canvases, signs, shelves, clocks, plants, sculptures, lighting, tools, etc. to a multiplicity of suitable mounting surfaces including, but not limited to, walls, posts, ceilings, floors, doors, fences, furniture, appliances, etc.

The rear side 104 of the mounting bracket 100 may be directly or indirectly coupled to the mounting surface, as described further below. In some embodiments, the mounting surface may extend or be oriented vertically or be angled vertically above horizonal.
[0085]As shown in FIG. 1, the front side 102 of the mounting bracket 100 may include at least one hook member or portion 110 that extends outwardly from a front face portion or surface 106. In some embodiments, the mounting bracket 100 may include a pair of hook members 110 extending outwardly from the front face 106, such as being positioned on opposing sides of a track portion of the mounting bracket 100 comprising a pair of guide, track or rail portions 115 and a slot 116 therebetween. The at least one hook member 110 may extend at an angle with respect to the front face 106, such as at an acute angle with respect to a top edge or side of the mounting bracket 100. The at least one hook member 110 may be configured to physically support a portion of an object thereon so that the mounting bracket 100 supports and couples the object to the mounting surface (when the mounting bracket 100 is affixed to the mounting surface). For example, the at least one hook member 110 may be configured to physically support at least one portion and/or hardware of an object (e.g., a hanging wire on the back of a frame or other object) thereon. The at least one hook member 110 may comprise any configuration or types of hooks or other connectors members or hardware that is configured to engage with and physically support a portion of an object, such as a portion of the object itself and/or hanging hardware attached to the object (e.g., eyes or circular rings, D-rings, sawtooth hangers, wires/ropes, nails/screws, hooks, keyholes, clips, other hooks, etc.).
[0086]In some embodiments, the guide portions 115 of the track portion of the mounting bracket 100 may each include a curved lip end portion 117 at a bottom or lower end of the mounting bracket 100 that is proximate to the bottom or lower end of the mounting bracket 100, as shown in FIG. 1. As shown in FIG. 1, the curved lip end portions 117 of the guide portions 115 may extend away from the front side 102 of the mounting bracket 102 and define free ends. The curved lip end portions 117 may be concave with respect to the front face 106. The curved lip end portions 117 may be arcuate and defined by one or more radii. In some other embodiments (not shown), the end lip end portions 117 may be linear (e.g., an angled flat or planar portion) or rectilinear. In some embodiments, the degree of the angle or curvature of the curved lip end portions 117 may be based on various factors such as, but not limited to, the size of the track portion and the length of the arm member 200. In some embodiments, the degree of the angle or curvature of the curved lip end portions 117 may be within the range of about 30 to about 70 degrees.
[0087]As shown in FIG. 7, the curved lip end portions 117 may be configured to force, direct or orient, and retain, an arm member 200 of the self-locking/closing device 300 into orientations such that the arm member 200 extends through the slot 116 and past the rear side 104 of the mounting bracket 102 (and potentially past a rear or back side of a base plate 105 coupled to the rear side 104 of the mounting bracket 102, of provided). The curved lip end portions 117 may thereby be configured to direct the arm member 200 past a rear or back side, surface or extent 124 of the self-locking/closing device 300 itself as the arm member 200 slides or translates along or over the curved lip end portions 117. In this way, when the back side 124 of the self-locking/closing device 300 (which may be the back side 104 of the mounting bracket 100 or the back side of the base plate 105 attached thereto, for example) is coupled to and abutting a mounting surface, the arm member 200 is unable to or prevented from sliding/translating fully through or past the curved lip end portions 117 because the mounting surface prevents the arm member 200 from rotating/orienting into the orientation(s) that would allow the arm member 200 pass through/over the curved lip end portions 117 (i.e., the arm member 200 would hot against the mounting surface and prevent proper orientation of the arm member 200 would that would allow the arm member 200 pass through/over the curved lip end portions 117), as shown in FIGS. 1 and 13D. The curved lip end portions 117 may thereby act to lock the arm member 200 in a fully closed position when back side 124 of the self-locking/closing device 300 is coupled to and abutting a mounting surface. Further, the curved lip end portions 117 may act to orient and retain the arm member 200 in a fully closed position with a portion of the arm member 200 (e.g., a tip portion 227 and/or projection thereof) positioned within the slot 116 and potentially against the mounting surface (when back side 124 of the self-locking/closing device 300 is coupled to and abutting a mounting surface). Further, in such embodiments, the arm member 200 must thereby be installed or loaded onto the curved lip end portions 117 of the track portion before or prior to the self-locking/closing device 300 being affixed to a mounting surface (e.g., a wall or other surface), as the mounting surface would prevent the arm member 200 from being oriented such that it extends bast the rear side 104 of the mounting bracket 102 to a sufficient degree (so that the curved lip end portions 117 can fit and extend between projections or posts 205 of the arm member 200, as described further below).
[0088]When the back side 124 of the self-locking/closing device 300 is not affixed or abutting the mounting surface (or another surface), the curved lip end portions 117 oriented the arm member 200 such that is extends past the back side 124, and thereby the arm member 200 can freely slide/translate fully through or past the curved lip end portions 117. In some embodiments, the arm member 200 may initially be introduced, assembled or coupled with the track portion of the mounting bracket 100 when the back side 124 of the self-locking/closing device 300 is not affixed or abutting the mounting surface (or another surface), as shown in FIG. 7.
[0089]As shown in FIGS. 1-3 and 7-13D, the guide portions 115 of the track portion of the mounting bracket 100 may extend from (e.g., may be contiguous with) the curved lip end portions 117. The guide portions 115 may extend upwardly from the curved lip end portions 117. In some embodiments, the guide portions 115 may extend linearly and parallel to each other (and the slot 116 formed therebetween may thereby extend linearly and include parallel sides). In some embodiments, inner surfaces of the guide portions 115 that define the slot or recess 116 therebetween may be flat/linear. For example, the inner surfaces of the guide portions 115 that define the slot or recess 116 therebetween may be planar and extend perpendicularly (and between) the front face 106 and the rear face 104 of the track portion. However, in other embodiments, the inner surfaces of the guide portions 115 may not be planar and/or may not be oriented perpendicular to the front face 106 and/or the rear face 104 of the track portion.
[0090]The guide portions 115 may define a thickness between the front face 106 and/or the rear face 104 of the track portion (e.g., measured perpendicularly between the front face 106 and the rear face 104). The guide portions 115 may define a constant thickness along their length (i.e., along the length of the track portion). For example, the front face 106 and/or the rear face 104 of the track portion may be planar and oriented parallel to each other. In some embodiments, each of the pair of guide portions 115 may define the same thickness as each other along the lengths thereof. In some embodiments, the thickness of the guide portions 115 may vary slightly along its length, such as by less than or equal to about a 25% variation, or by less than or equal to about a 10% variation.
[0091]As shown in FIGS. 1, 2, 8-11 and 13A-13D, an upper portion of the track portion (spaced from the curved lip end portions 117) of the mounting bracket 100 may include rotation portions 118. The rotation portions 118 may be provided at an upper end of the guide portions 115, and may be aligned with each other. The rotation recesses 118 may define upper ends of the guide portions 115. In some other embodiments, the guide portions 115 may extend past the rotation recesses 118.
[0092]The rotation portions 118 may include recesses or indentations in the rear or underside 104 (and/or front face 106) of the track portion. The lower sides of the recesses of the rotation portions 118 in the underside 104 of the track portion may smoothly transition from the underside 104 of the guide portions 115. For example, the recesses of the rotation portions 118 may arcuately extend (e.g., convexly) from the guide portions 115, as shown in FIGS. 1, 2, 10 and 13A-13D. The upper sides or ends of the rotation portions 118 opposing the guide portions 115 may transition or extend more sharply to the adjacent portions of the underside 104 than the lower sides of the rotation portions 118. The sides or ends of the rotation portions 11 may thereby define thicknesses beyond the recessed or indented portions that are thicker than the indentations/recesses to force or keep the arm member posts 205 within the indentations/recesses (and causing and/or allowing rotation of the arm member 200). The rotation portions 118 may thereby prevent the arm member 200 from leaving the top portion of the track portion (and specifically the rotation portions 118).
[0093]The rotation portions 118 may define a relatively thin portion of the track portion as compared to the thickness of the guide portions 115. In some embodiments, the rotation portions 118 may comprise relatively thin portions of the guide portions 115. As shown in FIGS. 1, 2, 8-11 and 13A-13D, the rotation portions 118 may define recesses or indentations in the underside 104 of the track portion such that the thickness between the front face 106 and the “lowest” or “bottom” portion of the underside 104 of the rotation portions 118 is relatively thinner than the thickness of the underside of the guide portions 115 and the front face 106. As explained further below, the relatively thin thickness of the rotation portions 118 of the track portion of the mounting bracket 100 allow the arm member 200 to be able to rotate from the closed potion into the open positioned (with respect to the mounting bracket 100), as shown in FIGS. 8-10. The “lowest” or “bottom” surface of the recesses in the underside 104 of the rotation portions 118 may comprise a convex surface or a planar surface, for example.
[0094]As shown in FIGS. 1, 7-11 and 13A-13D, the rotation portions 118 may extend at least partially beneath the hook portions 110. For example, the recesses of the rotation portions 118 in the underside 104 of the track portion may be positioned, at least partially, beneath the hook portions, as shown in FIGS. 1, 7-11 and 13A-13D. In some embodiments, the portions of the front face 106 comprising the guide portions 115 and the rotation portions 118 may be flat or planar. However, in other embodiments the rotation portions 118 may be positioned past the hook portions 110 such that the hook portions 110 are positioned between the rotation portions 118 and the curved lip end portions 117 (see, e.g., FIGS. 17-19, or the mounting bracket 100 may be void of the hook portions 110 (see, e.g., FIGS. 14, 16 and 17). In such embodiments, the rotation portions 118 may comprise portions of the front face 106 of the mounting bracket 100 (which may be planar and contiguous and parallel with planar portions of the front face 106 of the guide portions 115) and the recessed underside 104 portion of the track portion of the mounting bracket 100 (i.e., recessed with respect to at least the underside 104 portion of the guide portions 115 of the mounting bracket 100.
[0095]As shown in FIG. 3, in some embodiments, the back side 124 of the self-locking/closing device 300 may be defined by a base portion 105 and/or a cap portion 125 that are coupled to the mounting plate 100. As shown in FIG. 3, the base portion 105 may be coupled to the back side 104 of the mounting plate 100. The base portion 105 may include an aperture or recess that aligns with the track portion of the mounting plate 100 so that the base portion 105 does not interfere with the interaction of the arm member 200 and the track portion (i.e., the translation and rotation of the arm member 200 along/on the track portion). In this way, the underside 104 of the track portion may be exposed, as shown in FIG. 3. Further, the base portion 105 may act to space the mounting plate 100 away from the mounting surface. For example, the back side of the base portion 105 may define the back side 124 of the self-locking/closing device 300 that is coupled with an abuts the mounting surface. The base portion 105 may thereby space the underside 104 of the track portion of the mounting bracket 100 from the mounting surface when the self-locking/closing device 300 is affixed thereto. The base portion 105 may thereby prevent the mounting surface from interfering with the interaction of the arm member 200 and the track portion (i.e., the translation and rotation of the arm member 200 along/on the track portion).
[0096]As also shown in FIG. 3, the self-locking/closing device 300 may include the cap portion 125 coupled to the uppermost or top side/end of the mounting bracket 100 (and potentially the base plate 105). In some embodiments, the underside of the cap portion 125 may define a portion of the back side 124 of the self-locking/closing device 300. The cap portion 125 may define the upper-most profile of the mounting bracket 100 (and/or base plate 105). The cap portion 125 may be configured to substantially inhibit wires or other hanging means from catching on the top end of the mounting bracket 100 (and/or base plate 105). As shown ion FIG. 3, the cap portion 125 may include an outer cap surface that extends from the back side 124 to the front face 106 of the front side 102 of the mounting bracket 100. In some embodiments, the outer cap surface of the cap portion 125 may be arcuate, such as arcuately convex, as shown in FIG. 3. In some other embodiments, the outer cap surface of the cap portion 125 may be plana/linear or rectilinear.
[0097]Although the base portion 105 and the cap portion 125 are shown in FIG. 3 as separate and distinct components that are coupled (e.g., fixedly coupled) to the mounting bracket 100, the mounting bracket 100 and the base portion 105 may be integral and/or the mounting bracket 100 and the cap portion 125 may be integral (see, for example, FIGS. 15-19). As such, the mounting bracket 100 of the self-locking/closing device 300 may be integral or of one-piece construction (e.g., monolithic). In some such embodiments, the base portion 105 may be an integral portion of the mounting bracket 100 that form the backside 124 thereof and spaces the track portion from the mounting surface.
[0098]The mounting bracket 100 (and/or the base portion 105 and/or the cap portion 125) may be comprised of any material, such as, but not limited to, one or more plastic or polymer, metal, wood, ceramic, glass, composite material or a combination thereof. The mounting bracket 100 (and/or the base portion 105 and/or the cap portion 125) may be formed or manufactured via any appropriate process or processes, such as, but not limited to, molding (e.g., injection molding), machining, casting, forging, forming, 3D printing or another additive manufacturing process or a combination thereof.
[0099]FIGS. 4-6 illustrate an exemplary locking arm member or mechanism 200 of the self-locking/closing device 300. As shown in FIGS. 4-6, the arm member 200 includes at least two pairs of posts or projections 205 extending laterally from differing sides (e.g., opposing or opposite sides) of an end pivot portion of the arm member 200. The end pivot portion of the arm member 200 may be configured to be positioned within, and translate and rotate within, the slot 116 of the track portion.
[0100]The pairs of posts 205 may each include an upper post and a lower post. The upper posts of the pairs of posts 205 may be aligned with each other, and the lower posts of the pairs of posts 205 may be aligned with each other. Each pair of posts 205 may define a minimum spacing or distance therebetween. The space between the posts 205 of each pair of posts 205 may be slightly greater than (e.g., less than or equal 5% larger, less than or equal 10% larger or less than or equal 25% larger) the maximum thickness of the track portion of the mounting bracket 100. For example, the space between the posts 205 of each pair of posts 205 may be slightly larger than the maximum thickness of the guide portions 115 of the track portion, which may be thicker or the same thickness as the curved lip end portions 117 and thicker than the thickness of the rotation portions 118.
[0101]The pairs of posts 205 may thereby be configured to engage and translate along, and potentially rotated on, the track portion of the mounting bracket 100, as shown in FIG. 7-13D. As shown in FIG. 7-13D, the upper posts of the pairs of posts 205 may engage (extend over) and ride on front face 106 of the track portion and the lower posts of the pairs of posts 205 may engage (extend over) and ride on the underside 104 of the track portion. As shown in FIG. 7, the thickness of the curved lip end portions 117 relative to the minimum space between the pairs of posts 205 (and the orientation of the curved lip end portions 117) forces the arm member 200 into a locking closed position with respect to the mounting bracket 100 when the curved lip end portions 117 are positioned between the pairs of posts 205. Specifically, as shown in FIG. 7, the curved lip end portions 117 and the pairs of posts 205 may be configured (e.g., the clearance therebetween) such that the arm member 200 is angled or oriented into a position such that it extends through the slot 116 and past the back side 124 of the mounting bracket 100 when the pairs pf posts 205 are positioned in at least one location along the curved lip end portions 117 (i.e., when the pairs of posts 205 are mounted on the curved lip end portions 117 in the at least one location). The arm member 200 may thereby be installed on or removed from the curved lip end portions 117 while the mounting bracket 100 is removed from the mounting surface.
[0102]As shown in FIGS. 11 and 12, the curved lip end portions 117 and the pairs of posts 205 may be configured (e.g., the clearance therebetween) such that the arm member 200 can be translated along the curved lip end portions 117 from the locking fully closed position to a closed position proximate to (or mounted on) the guide portions 115. The curved lip end portions 117 and the pairs of posts 205 may be configured (e.g., the shape of the curved lip end portions 117 and the clearance therebetween) such that at least when the arm member 200 is positioned proximate to (or mounted on) the guide portions 115, the arm member 200 is re-oriented such that it no longer extends past the back side 124 of the mounting bracket 100, as shown in FIGS. 11 and 12. Rather, as shown in FIGS. 11 and 12, the tip of the arm member 200 may be repositioned above the back side 124 of the mounting bracket 100, such as within the slot 116, even with the front face 106 or above the front face 106.
[0103]The pairs of posts 205 of the arm member 200 and the guide portions 115 may be configured (e.g., the thickness of the curved lip end portions 117 relative to the minimum space between the pairs of posts 205 may be configured) to orient/force the arm member 200 into a closed position such that it is positioned above the back side 124 of the mounting bracket 100 and at least partially below the hook members 110 (if provided) and/or within the slot 116. The pairs of posts 205 and the guide portions 115 may thereby be configured to allow the pairs of posts 205, and thereby the arm member 200 as a whole, to translate along the length of the guide portions 115 when the back side 124 is positioned against a mounting surface. The pairs of posts 205 and the guide portions 115 may also be configured (e.g., the relative space therebetween) to prevent the arm member 200 from rotating with respect to the mounting bracket 100 out of the closed positioned, and potentially into an open position with the mounting bracket 100 (e.g., a tip, hook or other portion thereof) positioned away (i.e., spaced) from the front face 106 of the track portion of the mounting bracket 100. In the closed positioned or orientation, at least a portion of the arm member 200 may be positioned above the front face 106 of the mounting bracket 100 (e.g., at least the front face 104 of the track portion) and/or at least a portion of the hook portions 110 (if provided), as shown in FIG. 12.
[0104]The guide portions 115 (and potentially a portion of the curved lip end portions 117 extending from or positioned proximate to the guide portions 115) and the arm member 200 may be configured such that the arm member 200 is oriented/positioned in the closed orientation/position such that the tip portion 227 is positioned proximate to the front side 102 (e.g., the front face 106 thereof) of the mounting bracket 100. For example, as shown in FIGS. 11 and 12, in the closed position/orientation of the arm member 200, at least a portion of the arm member 200 may be positioned within the slot 116 (e.g., the arm member 200 may extend only partially through the slot 116). In some such embodiments, in the closed position/orientation of the arm member 200, a tip or end portion of the arm member 200 may be positioned within the slot 116 (i.e., positioned between the front face 106 of the mounting bracket 100 and the back side 104/124 of the mounting bracket 100 within the slot 116). In some other embodiments, in the closed position/orientation of the arm member 200, a tip or end portion of the arm member 200 may be positioned above/even with the slot 116 and/or even with the front side 102 (e.g., the front face 106 thereof) of the mounting bracket 100. In some other embodiments, in the closed position/orientation of the arm member 200, an underside of a tip portion 227 of the arm member 200 may be spaced from the front side 102 and/or front face 106 of the mounting bracket 100. The arm member 200 may thereby be angled with respect to the front side 102 and/or front face 106 of the mounting bracket 100. In some such embodiments, in the closed position/orientation of the arm member 200, the tip or end portion may be spaced above the front side 102 and/or front face 106 of the mounting bracket 100 by less than or equal to about 15 degrees (e.g., measured between the underside of the tip portion 227 of the arm member 200 and the front face 106 from the projections 205 engaging the front face of the track portion with respect to a top side of the mounting bracket 100).
[0105]In some embodiments, in the closed position/orientation of the arm member 200, the tip or end portion may be spaced above the front side 102 and/or front face 106 of the mounting bracket 100 within the range of about 15 degrees and about 5 degrees (e.g., measured between the underside of the tip portion 227 of the arm member 200 and the front face 106 from the projections 205 engaging the front face of the track portion with respect to a top side of the mounting bracket 100). In some embodiments, in the closed position/orientation of the arm member 200, the tip or end portion may be spaced above the front side 102 and/or front face 106 of the mounting bracket 100 less than or equal to about 10 degrees, or about 5 degrees (e.g., measured between the underside of the tip portion 227 of the arm member 200 and the front face 106 from the projections 205 engaging the front face of the track portion with respect to a top side of the mounting bracket 100). In some embodiments, in the closed position/orientation of the arm member 200, the tip or end portion may be spaced above the front side 102 and/or front face 106 of the mounting bracket 100 less than about 10%, or less than about 5%, of the spacing thereof in the open position/orientation of the arm member 200 (e.g., measured between the underside of the tip portion 227 of the arm member 200 and the front face 106 from the projections 205 engaging the front face of the track portion with respect to a top side of the mounting bracket 100).
[0106]In the closed position, the arm member 200 may form an enclosed space or gap positioned above the front
