ABSTRACT:
A self adjusting shim device has an elastic outer bladder formed of resilient material filled ith bouncing putty. The bouncing putty filler will deform slowly under the slightest force like a highly viscous liquid but will resist rapidly applied loads as if it were a solid. The shim device is placed between the bottom of an article, such as one or more legs of a piece of furniture, and the weight of the article supported on the shim device will, in a short time, cause the shim device(s) to deform and the article supported will assume a state of equilibrium, even if the legs are of unequal length. A sudden downward force applied to the supported article will create a compressive force on the resilient bladder causing the bouncing putty filler to become rigid and resist the downward force. When the downward force is lessened or removed, the bladder tends to return to its original shape. In another embodiment, the elastic bladder is contained within a pair of opposed rigid cup-shape members telescopically joined together and adapted to be installed on the bottom of articles.
