Sheet metal cable hook
A cable hook includes attachment means with a substantially base having a plantar bottom surface. The hook portion extends upwardly from the base ( 17 ) and includes upper and lower jaws ( 21, 23 ) with a lateral opening that is substantially circular. A single, laterally-extending notch ( 20 ) is located on the inside surface of the upper jaw proximate a frontal opening ( 22 ) between the jaws. Orientation marks ( 12 ) are included on the bottom surface of the base ( 17 ). Panel attachment means ( 18 ) are preferably deformer undercut grooves ( 16 ) for receiving the cold flow of metal from a metal panel ( 19 ) attached thereby. The hook ( 10 ) may be used to secure cables, a spring, a rod, tubing, or shaft.
1 . A cable hook having self-clinching attachment means, comprising:
a substantially rectangular base having a planar bottom surface and further including panel attachment means located on opposing front and rear side surfaces thereof;
a hook portion extending upwardly from said base, said hook portion including upper and lower jaws forming a substantially circular C-shaped hook with a frontal opening of substantially less than 180 degrees measured from an axis of the hook, said opening located between spaced ends of said jaws; and
a single laterally extending notch on the inside surface of said upper jaw proximate said frontal opening.
2 . The device of claim 1 wherein said jaws have a continuous arcuate inside surface except for said notch.
3 . The device of claim 2 wherein said base further includes orientation marks on the bottom planar surface thereof proximate only one of said front or rear sides.
4 . The device of claim 1 wherein said panel attachment means are deformer undercut grooves for receiving the cold flow of metal from a panel attached thereby.
6 . The device of claim 1 further including an insert which encompasses the inside surface of the jaws and partially encompasses the lateral sides of the fastener adjacent the lateral opening.
7 . The device of claim 6 wherein the insert covers the edges of the jaws.
8 . The device of claim 7 wherein said insert further includes a pivotable flap that lies across the frontal opening to positively retain items held within the hook.
9 . The device of claim 8 wherein the flap is unitary with said insert and resiliently biased toward a closed position.
10 . The device of claim 1 further including a spring-biased catch which covers the frontal opening of the fastener to positively retain items held within the hook.
11 . The device of claim 10 wherein said insert includes two opposing ears which have inward-facing dimples that engage cooperating recesses on opposite sides of the lower jaw to provide a pivot for said catch.
12 . The device of claim 111 wherein said insert includes a tail portion which is free to slide against the inside surface of the lower jaw to provide a spring force to close said catch.
13 . The device of claim 12 wherein said insert is composed of metal.
14 . The device of claim 12 wherein said insert is composed of an electrically non-conductive thermoplastic.
15 . The device of claim 6 further described in that said insert is a continuous cylinder covering said frontal opening.
16 . A cable hook having self-clinching attachment means, comprising:
a substantially rectangular base having a planar bottom surface and further including panel attachment means located on opposing front and rear side surfaces thereof;
a hook portion extending upwardly from said base, said hook portion including upper and lower jaws forming a substantially C-shaped hook with a frontal opening located between spaced ends of said jaws;
a single laterally extending notch on the inside surface of said upper jaw proximate said frontal opening; and
said base further including orientation marks on the bottom planar surface thereof proximate only one of said front or rear sides.
