Abstract

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.

First claim

The invention claimed is:

1. An apparatus for a cylindrical lockset adapted to be mounted within doors having different door thicknesses, the cylindrical lockset structured to be coupled to a latch that is mounted to the door, the apparatus comprising:
a lock body having a slot, at least a portion of the lock body being selectively rotatable displaceable to facilitate linear displacement of at least a portion of the latch relative to the door;
an adjustment plate adapted to be adjustably mounted to the lock body; and
a removable gauge insert having a plurality of positive stop arrangements, the 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, the plurality of positive stop arrangements including at least a first positive stop arrangement and a second positive stop arrangement, the first positive stop arrangement including a first positive stop separated from an adjacent end of the removable gauge insert by a first longitudinal distance, the second positive stop arrangement including a second positive stop separated from an adjacent end of the removable gauge insert by a second longitudinal distance, the first longitudinal distance being different than the second longitudinal distance.

2. The apparatus of claim 1 , wherein the adjustment plate includes an annular portion having an edge, the annular portion configured for the edge to contact one of a plurality of positive stops of the removable gauge insert when the adjustment plate is separated from a portion of the lock body by the axial distance.

3. The apparatus of claim 2 , wherein the annular portion includes an interior thread, and wherein the frictional engagement between the adjustment plate and the removable gauge insert is a threaded engagement between the interior thread and the removable gauge insert.

4. An apparatus for a cylindrical lockset adapted to be mounted within doors having different door thicknesses, the cylindrical lockset structured to be coupled to a latch that is mounted to the door, the apparatus comprising:
a lock body having a slot, at least a portion of the lock body being selectively rotatably displaceable to facilitate linear displacement of at least a portion of the latch relative to the door;
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, wherein the removable gauge insert includes a plurality of legs and a plurality of positive stops, and wherein each of the plurality of positive stop arrangements include a longitudinal distance, the longitudinal distance being a distance between one of the plurality of positive stops and an end of a non-adjacent leg of the plurality of legs, the longitudinal distance being different for each of the plurality of positive stop arrangements.

5. The apparatus of claim 1 , wherein the removable gauge insert includes a first longitudinal side and a second longitudinal side, the first and second longitudinal sides being on opposing sides of the removable gauge insert and each sized for insertion into the slot, and further wherein the plurality of positive stops includes a third positive stop arrangement having a third positive stop that is separated from the first end of the removable gauge insert by a third longitudinal distance, the first, second, and third longitudinal distances being different from each other, and wherein the first and second positive stops are positioned about the first longitudinal side and the third positive stop is positioned about the second longitudinal side of the removable gauge insert.

6. The apparatus of claim 4 , wherein the removable gauge insert provides an indicia of the axial distance for each of the plurality of positive stop arrangements.

7. The apparatus of claim 6 , wherein the indicia for at least one of the plurality of positive stop arrangements has a different shape than the indicia for at least another of the plurality of positive stop arrangements.

8. The apparatus of claim 7 , wherein the different shape is substantially an arrow shape.

9. The apparatus of claim 4 , wherein the adjustment plate further includes a flange adapted to contact a face of the door when the body portion is positioned in a mounting hole in the door, the flange having a plurality of apertures arranged for alignment with supplemental mounting holes in the door.

10. An apparatus for a cylindrical lockset adapted to be mounted within doors having different door thicknesses, the cylindrical lockset structured to be coupled to a latch that is mounted to the door, the apparatus comprising:
a body portion having at least one slot, at least a portion of the body portion being selectively rotatably displaceable to facilitate linear displacement of at least a portion of the latch relative to the door;
an adjustment plate adapted to be adjustably mounted to the lock body; and
at least one gauge insert adapted to be removably received in the at least one slot, the at least one gauge insert having a first portion and a second portion, the first portion comprising a plurality of stops, each of the plurality of stops adapted to provide a different axial position for the adjustment plate relative to at least the body portion, the second portion comprising a plurality of legs, the plurality of legs adapted to frictionally engage the adjustment plate to resist movement of the adjustment plate away from the axial position.

11. The apparatus of claim 10 , wherein each of the plurality of positive stops are separated from a non-adjacent leg of the plurality of legs by a longitudinal distance, the longitudinal distance being different for each of the plurality of stops, and wherein each of the positive stops are positioned for the first portion to be configured to provide a plurality of axial positions for the adjustment plate.

12. The apparatus of claim 10 , wherein the second portion is frictionally engaged with an annular portion of the removable insert by a threaded engagement, and wherein the second portion includes a chamfer configured to facilitate the threaded engagement.

13. The apparatus of claim 10 , wherein the lock body is configured to be positioned in the door between an interior handle and an exterior handle for operating a latch.

14. An anti-rotational assembly for a cylindrical lockset for a door, the cylindrical lockset structured to facilitate displacement of at least a portion of a latch, the anti-rotational assembly comprising:
an inside hub having a receptacle that includes a cavity and a pair of channels, the pair of channels configured to longitudinally extend along opposing sides of the cavity, the inside hub structured to accommodate rotational displacement of at least a portion of the cylindrical lockset within, and relative to, the inside hub to facilitate selective displacement of at least a portion of the l
