Adjustment Plate Gauge Insert and Adapter for Hands-Free Lock Installation

摘要

A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis. The anti-rotation assembly may include a retention member that is secured to an inside hub of a lock chassis. As an anti-rotation member is displaced in a first axial direction along the inside hub to a mount position, the anti-rotational member may deflect resilient members of the retention member. With the anti-rotation member at the mounted position, the anti-rotation member may be in a frictional engagement with the previously deflected resilient members so that anti-rotation member is retained at the mount position.

主权项

1. A door lock chassis adapted to be mounted within doors having different door thicknesses, the door lock chassis comprising:
a lock body having a slot; an adjustment plate adapted to be adjustably mounted to the lock body; and a removable gauge insert adapted to frictionally engage the adjustment plate and to be received in the slot at one of a plurality of positive stop arrangements, each of the plurality of positive stop arrangements configured to, when the adjustment plate is operably mounted to the lock body, separate the adjustment plate from a portion of the lock body by an axial distance, the axial distance being different for each of the plurality of positive stop arrangements.
