Abstract:
1. An interchangeable foil system, comprising: a removable foil comprising a tab protruding from a base, and a foil mounting assembly, comprising: a sleeve having a ball on an outer surface and a receptacle configured to receive the tab, a retainer extending within the receptacle and engage-able with the tab, a socket containing the sleeve and the retainer in a chamber and seating the ball rotatably in a cup, a resilient pad between the sleeve and an inner wall of the chamber, and a lid confining the sleeve, the retainer, and the pad within the socket and having a slot through which the tab may enter the receptacle, where the tab is inserted through the slot into the receptacle in an insertion direction, where the retainer retains the tab in the receptacle until the tab is pulled in a direction opposite the insertion direction with at least a minimum removal force, where a lateral pressure on the foil when the tab is in the receptacle causes the sleeve to yaw and roll in the chamber as the ball rotates in the cup, and where the pad exerts a restoring force to return the sleeve to a neutral orientation as the lateral pressure subsides.
