Cam-action anti-roll button

摘要

A cam-action anti-rolling mechanism for buttons is described herein. One embodiment may take the form of a button having a body with a slot extending therethrough. The slot has a normal orientation to a direction of motion for the button. The button also includes a cam bar having a first portion extending through the slot and a second portion offset from and parallel to the first portion. The cam bar is coupled in a slip fit manner within the slot to the body and the second portion provides a rotational axis for the cam bar. A fixture coupled to the second portion of the cam bar is provided to allow for rotation of the cam bar.

主权项

1. A one-sided anti-roll button comprising:
an elongated body comprising an aperture extending lengthwise therethrough; a cam bar extending through the aperture and coupled thereto in a slip fit manner, the cam bar being configured to move within the aperture as the button moves within its axis of motion; a cam member coupled to the cam bar, the cam bar extending substantially perpendicular in a first direction therefrom; and a rotational bar coupled to the cam member and extending substantially perpendicular to the cam member in an opposite direction from the first direction thereby forming a step shape with the cam bar and cam member, the rotational bar being offset from and parallel to a line that contains the cam bar.
