Abstract

A pin assembly for a retractable pin mechanism of a slider box of a heavy-duty vehicle includes a pin guide attached to the slider box. A pin is connected to a retraction mechanism and engages the pin guide. The pin includes an integral inboard and outboard stop. The integral inboard and outboard stops of the pin limit movement of the pin with respect to the pin guide and serve as a positive stop for the pin during retraction and extension of the pin when the retraction mechanism is activated or deactivated by the operator of the vehicle.

First claim

What is claimed is:

1. A pin assembly for a retractable pin mechanism of a slider box of a heavy-duty vehicle comprising:
a pin guide formed with an opening and inboard and outboard surfaces, and configured to be attached to said slider box,
a pin body operatively connected to a retraction mechanism, said pin body extending through said pin guide opening, the pin body being formed in one-piece and including an inboard stop comprising a shoulder, said pin assembly including an outboard stop, whereby said inboard stop limits inboard movement of said pin body by contacting said pin guide outboard surface when the pin body is moved to a retracted inboard position and the bias of a spring of the pin assembly is overcome, so that said pin assembly spring is not fully compressed, and whereby said outboard stop limits outboard movement of said pin body by contacting said pin guide inboard surface when the pin body is biased to an extended outboard position by the pin assembly spring.

2. A pin assembly for a retractable pin mechanism of claim 1 , said outboard stop comprising a stem fastened to said pin body.

3. A pin assembly for a retractable pin mechanism of claim 1 , said pin body further comprising a pin end having a generally D-shape.

4. A pin assembly for a retractable pin mechanism of claim 1 , wherein said retraction mechanism is an inflatable bladder.
