Abstract
A shim for appliances such as windows and doors is described herein. The shim includes a stack of two or more cylinders threaded together such that twisting one or more of the cylinders causes the shim to extend. A collar cylinder may be placed through a jamb of the door or window, where an inner wall of the collar has threads. An inner cylinder is placed inside the collar, where the inner cylinder has male threads, and the inner cylinder is configured to extend when the inner cylinder is rotated relative to the collar. In some cases, a ball is mechanically connected to the inner cylinder at one end and is configured to extend away from the jamb when the inner cylinder is rotated relative to the collar. Some cases include a shim base with a ball socket configured to receive the ball.
Claims20
A window shim comprising:
- a collar placed through a jamb of a window, where an inner wall of the collar has threads;
- an inner cylinder placed inside the collar, where the inner cylinder has male threads, the inner cylinder configured to extend when the inner cylinder is rotated relative to the collar;
- a ball mechanically connected to the inner cylinder at one end, configured to extend away from the jamb when the inner cylinder is rotated relative to the collar;
- and
- a middle cylinder placed between the collar and the inner cylinder, where the middle cylinder has male threads on an outer wall, the middle cylinder configured to extend when the middle cylinder is rotated relative to the collar.
A door shim comprising:
- a collar placed through a jamb of a door, where an inner wall of the collar has threads;
- an inner cylinder placed inside the collar, where the inner cylinder has male threads, the inner cylinder configured to extend when the inner cylinder is rotated relative to the collar;
- a ball mechanically connected to the inner cylinder at one end, configured to extend away from the jamb when the inner cylinder is rotated relative to the collar;
- and
- a middle cylinder placed between the collar and the inner cylinder, where the middle cylinder has male threads on an outer wall, the middle cylinder configured to extend when the middle cylinder is rotated relative to the collar.
