US Patent:

45070342, Mar 26, 1985

Filed:

Oct 1, 1982

Appl. No.:

6/432266

Inventors:

Wing G. Lew - Los Angeles CA
Richard A. Deutsch - Tarzana CA
Mojtaba Nasserian - Northridge CA

Assignee:

Adjustable Bushing Corporation - North Hollywood CA

International Classification:

F16B 3904

US Classification:

411 21

Abstract:

A pin mounts a plurality of expandable and contractable bushings that upon expansion engage the bore of workpieces to hold the latter together. A ball lock expands behind the workpieces to present a positive lock against axial pullout of the fastener. The bushings are alternate male and female, split ring bushings that have complementary contiguous surfaces that act as wedges. Upon axial compressive loading the female bushings expand and the male bushings contract. The ball lock includes a pair of diametrically opposed balls radially displaceable in the pin. A slide has an annular recess for receiving the balls in a withdrawn position within the pin. A spring normally biases a land of the slide into a position radially inside the balls to rigidly hold the balls in their extended position.

Appl. No.:

6/381724

Inventors:

Richard A. Deutsch - Encino CA

Assignee:

Adjustable Bushing Corp. - North Hollywood CA

International Classification:

F16B 2114

US Classification:

411 33

Abstract:

An improvement to expansible bushing type locking pins which include a handle or clip having camming means at one end to operate the bushings. Such handles or clips include an opening which cooperates with the adjusting nut on the free end of the locking pin to secure the assemblage together and in place on the parts to be assembled using the locking pin and clip assembly. The improvement comprises a nose cone on the free end of the locking pin having a circular cross-sectional shape, the nose cone overlying the adjusting nut so that the criticality of position of the nut on the pin in the prior art is avoided, while at the same time the tapered nose cone provides a guiding function to mount the pin into the parts to be assembled together.
