## 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.

## Claims

### Claim 1

A hook assembly comprising:
a substrate to be mounted on a surface, the substrate comprising three tabs arranged in a triangular configuration;
a hook comprising a pair of opposing side flaps;
a tripod mounting member configured to couple the hook to the substrate, the tripod mounting member comprising:
three legs arranged in a triangular configuration, the three legs corresponding to the three tabs of the substrate;
a pair of opposing side plates extending from two rear legs of the three legs; and
a stopper groove;
a torsion spring comprising a pair of arms extending from opposite ends of the torsion spring; and
a first fastener configured to couple the tripod mounting member to the substrate;
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,
wherein, when the hook assembly is in an assembled state:
the side plates of the tripod mounting member are between the side flaps of the hook,
the legs of the tripod mounting member are overlapped by the tabs on the substrate,
the torsion spring extends between the side plates of the tripod mounting member and is wound around at least a portion of the second fastener, and
one arm of the pair of arms of the torsion spring extends into the stopper groove of the tripod mounting member and the other arm of the pair of arms of the torsion spring engages the hook.

### Claim 2 (depends on 1)

The hook assembly of claim 1, wherein the three tabs are stamped.

### Claim 3 (depends on 1)

The hook assembly of claim 1, wherein the stopper groove is not centered between the two rear legs.

### Claim 4 (depends on 1)

The hook assembly of claim 1, wherein the first fastener is a rivet.

### Claim 5 (depends on 1)

The hook assembly of claim 1, wherein the second fastener is a rivet.
