Abstract
An adjunct part can be secured to a host part, where the host part defines a recess configured to allow a threaded fastener to secure the host part to a further part. The adjunct part has a resilient boss projecting therefrom and adapted to enter the recess, the boss having an axially extending opening to receive a threaded tightening member. The boss and the threaded tightening member have configurations which allow the tightening member, as it advances into the boss along the opening, to resiliently urge portions of the boss radially outward into binding contact with the interior of the recess, thereby fastening the adjunct part to the host part.
Claims9
To facilitate the attachment of a moulded adjunct enclosure to a host enclosure, in which the host enclosure exhibits a recess wherein said entire recess has a cylindrical internal surface formed by side walls and a bottom wall:
- the combination, with the adjunct enclosure, of a resilient boss integral to and of unitary construction with said adjunct enclosure, said boss projecting from the adjunct enclosure and adapted to enter said recess and be captured between said side walls and said bottom wall of said recess, the boss having an axially extending opening to receive a threaded tightening member, the boss and the threaded tightening member, further having configurations which allow said tightening member, as it advances into the boss along said opening, to resiliently urge portions of said boss radially outward into binding contact with the side walls of the recess, thereby fastening the adjunct enclosure to the host enclosure.
In combination, a first host part exhibiting a recess formed by walls extending below a top surface of said host part, said entire recess having a cylindrical internal surface, said host part further comprises an aperture through a bottom wall of said recess;
- a second adjunct part having a resilient boss integral with and of unitary construction with said adjunct part, projecting from the adjunct part and extending within said recess and not protruding beyond said recess, the boss having an axially extending opening in which is screwed a threaded tightening member, the boss and the threaded tightening member having configurations which that said tightening member, screwed fully into said opening, resiliently urges portions of said boss radially outward into binding contact with the internal surface of the recess, thereby fastening the adjunct part to the host part;
- and,
- a third part secured to said host part by a fastening member extending through said aperture of said recess bottom wall.
