US12385706 - Button detent retension method for spring loaded linear actuating device

The patent describes a magazine catch mechanism that utilizes a threaded rod and a button base to facilitate the alignment and release of a magazine through a spring-loaded system. The button features an integrally formed design that allows for user interaction while ensuring proper engagement with the button base during operation.

Claim 1

1. A magazine catch, comprising: a rod extending along a longitudinal axis, the rod comprising threads on a first end and a bar on a second end; a button base with a bore extending therethrough, wherein the rod is configured to extend through the bore of the button base; a spring disposed around the rod, wherein a first end of the spring contacts the button base and a second end of the spring bears against a receiver; and a button comprising a first end with a planar profile configured to be pressed by a user to release a magazine and a second end with internal threads which are configured to be threaded onto the rod, the first end with the planar profile and the second end with the internal threads being integrally formed, the button comprising an extension configured to be placed within the button base, wherein during rotation of the button a first set of surfaces on the button base are configured to engage with a second set of surfaces on the button such that pressure aligns the button base and the button, wherein the receiver restrains rotational motion of the bar relative to the button base. a rod extending along a longitudinal axis, the rod comprising threads on a first end and a bar on a second end; a button base with a bore extending therethrough, wherein the rod is configured to extend through the bore of the button base; a spring disposed around the rod, wherein a first end of the spring contacts the button base and a second end of the spring bears against a receiver; and a button comprising a first end with a planar profile configured to be pressed by a user to release a magazine and a second end with internal threads which are configured to be threaded onto the rod, the first end with the planar profile and the second end with the internal threads being integrally formed, the button comprising an extension configured to be placed within the button base, wherein during rotation of the button a first set of surfaces on the button base are configured to engage with a second set of surfaces on the button such that pressure aligns the button base and the button, wherein the receiver restrains rotational motion of the bar relative to the button base.
