Abstract
A panel fasteners (20) is disclosed in the form of a hook and cam assembly (21) having two side walls (24) with a boss (27) through which a cam shaft (28) is journalled. The cam shaft has a socket (29) and a round cam (30). A hook (32) is frictionally mounted in camming engagement with the cam. A leaf clutch spring (33) is mounted within a spring mounting notch (36) and in frictional engagement with a substantially round cam engagement hole (34) of the hook. To position the spring into the spring mounting notch and cam engagement hole the spring is pre-compressed prior to mounting it within the spring mounting notch by forcing it through a narrowing channel positioned adjacent the cam.
Claims9
A panel fastener for insulated panels comprising:
- a pair of sidewalls each having a boss therethrough;
- a cam rotatably positioned within said boss of each said sidewall, said cam having a spring mounting notch;
- a spring mounted within said spring mounting notch of said cam, and
- a hook extending from said pair of sidewalls and having a generally round cam engagement hole therethrough and a catch extending past said pair of sidewalls, said cam being positioned within said round cam engagement hole with said spring extending outwardly to frictionally engage said round cam engagement hole,
- whereby contact between the spring and the hook round cam engagement hole causes frictional contact sufficient to rotate the hook through rotation of said cam.
A panel fastener for insulted panels comprising:
- a housing having at least boss hole therethrough;
- a hook having a catch end, said hook having a substantially round cam engagement hole therethrough;
- a cam extending through said housing boss and rotatably mounted within said hook round cam engagement hole, said cam having spring mounting notch and a spring positioned at least partially within said spring mounting notch so as to be biased against said hook round cam engagement hole,
- whereby frictional contact between the spring and the hook round cam engagement hole causes rotation of said hook with the rotation of said cam.
A method of manufacturing a panel fastener for insulated panels comprising the steps of:
- (A) providing a housing having a boss therethrough, a hook having a substantially round cam engagement hole therethrough, a cam having spring mounting notch, and a compressible spring;
- (B) positioning the hook within the housing with the round cam engagement hole of the hook axially aligned with the boss of the housing, and positioning the cam within the round cam engagement hole of the hook and the boss of the housing;
- (C) compressing the spring, and
- (D) positioning the compressed spring while in its compressed condition into the spring mounting notch of the cam and in frictional contact with the round cam engagement hole of the hook.
