Title:
TENSION SPRING MOUNT
Document Type and Number:
WIPO Patent Application WO/2011/106260
Kind Code:
A3
Abstract:
End mounts are used to secure a helical tension spring to end fixtures with various shapes and sizes. These end mounts contain an inner hole to encase the inner spring end mount and secure the end mount making it like a cap. There is also a keyhole created in the top surface that goes through the end mount allowing it to fit over the fixtures but not over the inner end mount, holding it in place. Grooves are machined in a helical pattern on the cylindrical side wall of the end mount. The spring is wound onto the grooves of the end mount.
