Hook

Abstract

A hook assembly includes a substrate having three tabs arranged in a triangular configuration, a hook including a pair of opposing side flaps, and a tripod mounting member configured to couple the hook to the substrate. The tripod mounting member includes three legs arranged in a triangular configuration, a pair of opposing side plates extending from two rear legs of the three legs, and a stopper groove. The three legs of the tripod mounting member correspond to the three tabs of the substrate. The hook assembly also includes a torsion spring having a pair of arms extending from opposite ends of the torsion spring, a first fastener configured to couple the tripod mounting member to the substrate, and a second fastener configured to extend through the side plates of the tripod mounting member and the side flaps of the hook to rotatably couple the hook to the tripod mounting member.

DETAILED DESCRIPTION

(6) The present disclosure is directed to various embodiments of a hook assembly configured to mitigate swiveling of a hook and thereby enhance fixation of the hook to a structure, such as a wall or a ceiling, and/or to a fixture (e.g., the body of a light fixture installed on a ceiling). The assembly may be coupled either directly or indirectly to the structure and/or the fixture.

(7) With reference to FIGS. 1-5, a hook assembly according to one embodiment of the present disclosure includes a substrate 10 configured to be installed on or in a surface (e.g., a wall), a tripod mounting member 20, a spring 30 (e.g., a torsion spring), and a hook 40. The tripod mounting member 20 is configured to couple the hook 40 to the substrate 10. The hook 40 is configured to support a lighting fixture or any other suitable product. In the illustrated embodiment, the hook assembly also includes a first fastener 50 (e.g., a rivet) for coupling the tripod mounting member 20 to the substrate 10 and a second fastener 60 (e.g., a pin) for rotatably coupling the hook 40 to the tripod mounting member 20.

(8) In the illustrated embodiment, the substrate 10 includes three buckles or tabs 101 extending outward from an outer surface of the substrate 10. Each of the tabs 101 defines a slot for receiving a portion of the tripod mounting member 20, as described in more detail below. In the illustrated embodiment, the tabs 101 are arranged in a triangular configuration, although in one or more embodiments the tabs 101 may be arranged in any other suitable configuration. The tabs 101 may be formed in the substrate 10 by any suitable manufacturing process or technique, such as press-molding (e.g., stamping).

(9) In the embodiment illustrated in FIG. 2, the hook 40 includes an arcuate body portion, a pair of opposing side flaps 401 located at one end of the arcuate body portion, and a lip (e.g., a return flange) located at an opposite end of the arcuate body portion. Although in the illustrated embodiment the body portion of the hook 40 is curved, in one or more embodiments the body portion of the hook 40 may be straight or substantially straight. The pair of opposing side flaps 401 is configured to connect the hook 40 to the tripod mounting member 20.

(10) In the embodiment illustrated in FIG. 3, the tripod mounting member 20 includes a raised segment defining a stopper groove or channel 201, a pair of opposing side plates 202, and three legs 203 arranged in a triangular configuration (e.g., the mounting member 20 includes a front leg and a pair of opposing rear legs). The side plates 202 of the tripod mounting member 20 correspond to the side flaps 401 of the hook 40. In the illustrated embodiment, the side plates 202 are located along inside edges of the pair of rear legs 203. Additionally, in the illustrated embodiment, the side plates 202 extend up from the pair of rear legs 203 at a 90-degree angle or substantially a 90-degree angle (i.e., the side plates 202 are orthogonal or substantially orthogonal to the rear legs 203), although in one or more embodiments, the side plates 202 may extend up from the pair of rear legs 203 at any other angle corresponding to the orientation of the side flaps 401 on the hook 40. Additionally, the three legs 203 of the tripod mounting member 20 are configured (e.g., sized and positioned) to mate or engage with the three tabs 101 on the substrate 10 (e.g., the three legs 203 of the tripod mounting member 20 correspond to the three tabs 101 on the substrate 10). In the illustrated embodiment, the stopper groove 201 is located proximate to one of the rear legs 203 (e.g., the stopper groove 201 is not centered between the two rear legs 203) and extends lengthwise between one of the rear legs 203 and the front leg 203.

(11) As illustrated in FIGS. 4-5, when the hook assembly is assembled, at least a portion of each of the legs 203 of the tripod mounting member 20 extend into corresponding slots defined by the tabs 101 on the substrate 10. When the legs 203 of the tripod mounting member 20 extend into the slots in the substrate 10, the tabs 101 on the substrate 10 overlap or overhang at least a portion of the legs 203 of the tripod mounting member 20. Additionally, in the illustrated embodiment, when the hook assembly is assembled, the side flaps 401 of the hook 40 are positioned outside of the corresponding side plates 202 of the tripod mounting member 20 (i.e., the side plates 202 of the tripod mounting member 20 extend between the side flaps 401 of the hook 40), the spring 30 extends between the opposing side plates 202 of the tripod mounting member 20, and the second fastener 60 extends through openings in the side flaps 401 of the hook 40 and corresponding openings in the side plates 202 of the tripod mounting member 20 to rotatably couple the hook 40 to the tripod mounting member 20. In the illustrated embodiment, the spring 30 is wound around at least a portion of the second fastener 60 (e.g., the second fastener 60 extends through an opening defined by the torsion spring 30). Although in the illustrated embodiment the second fastener 60 is a rivet, in one or more embodiments, the second fastener 60 may be any other type or kind of fastener suitable for rotatably coupling the hook 40 to the tripod mounting member 20, such as a pin. The engagement between the legs 203 of the tripod mounting member 20 and the tabs 101 of the substrate 10 is configured to prevent the tripod mounting member 20, and the hook 40 coupled thereto, for swiveling relative to the substrate 10. That is, the tripod mounting member 20 is configured to properly position and secure the hook 40 on the substrate 10. Accordingly, the hook assembly of the present disclosure is configured to provide a stable structure to support lighting fixtures or other products, unlike related art spring hooks that incorporate screws and/or nuts, which are prone to failure or disengagement due to unthreading.

(12) Additionally, in the illustrated embodiment, spring 30 includes a pair of pins or arms 301, 302 located at opposite ends of the spring 30. In the illustrated embodiment, the wound portion of the spring 30 is aligned or substantially aligned with the side plates 202 of the tripod mounting member 20 and side flaps 401 of the hook 40, and the arms 301, 302 on the ends of the spring 30 extend out toward the front tab 101 on the substrate 10. In the illustrated embodiment, when the hook assembly is assembled, one of the arms 302 of the spring 30 engages an outer surface of the hook 40 and the other arm 301 of the spring 30 is received in the stopper groove 201 of the tripod mounting member 20 (e.g., the tripod stopper groove 201 of the tripod mounting member 20 retains and overlaps one of the arms 301 of the spring 30 and the other arm 302 of the spring 30 overlaps an outer surface of the hook 40. Accordingly, when the hook 40 is pulled (e.g., rotated away from the substrate 10), the engagement between one of the arms 302 of the spring 30 and the hook 40 causes the spring 30 to wind more tightly. When the hook 40 is released, the restorative force created by the more tightly wound spring 30 tends to force hook 40 to rotate back toward the substrate 10. In this manner, the spring 30 is configured to bias the hook 40 to return to its initial position.
