ABSTRACT:
The concept of resilient pressure fit is extended to permit ready modification according to the preference of the wearer. In particular, according to the invention, a telescopic connection mechanism includes a vertically disposed male element with a male railway which mates, in a telescopic relation, with a vertically disposed female element having a female guideway, wherein the male element is provided with an insert-receiving recess of predefined size and shape forming a transverse-oriented slot for receiving a selected variety of inserts which lock into the slot. The inserts cannot be removed from the recess slot while the male element is engaged by the female element, but the insert is readily removable from the male element when not engaged by the female element. The recess slot is bordered by wings transverse of the engagement axis of the male element and the female element.
An insert is useful for forming a lock to a latch means transverse of and in the female guideway. Various types of inserts may be used, each insert having a unique use or characteristic based on structural shape and resiliency. Each type of insert is so formed to be insertable in the slot so as to resist removal of the insert from the male element except upon the application of properly directed force transverse of the direction of the element engagement axis. Either a dental professional or the user of the appliance may remove and easily renew an insert should the insert ever wear out during the life of the appliance or should the user wish to change the fit characteristics.
