Abstract

A mounting system for a door lock is provided. The mounting system may include a chassis having a pocket and an attachment bracket. The attachment bracket may include at least one attachment post extending parallel to an attachment post axis and a retaining plate affixed to the at least one attachment post. The attachment bracket may move relative to the chassis between at least a first position and a second position to provide different mounting patterns for a variety of associated door lock components such as exit devices or trims.

Claims (32)

1 . A mounting system for a door lock, the mounting system comprising:

a chassis comprising a pocket; and

a sliding attachment bracket comprising:

at least one attachment post extending parallel to an attachment post axis; and

a retaining plate affixed to the at least one attachment post,

wherein the pocket is configured to receive the retaining plate, wherein the pocket is configured to allow the retaining plate to slide orthogonal to the attachment post axis,

wherein the pocket is further configured to inhibit rotation of the retaining plate about the attachment post axis, and wherein the sliding attachment bracket comprises a first hole and a second hole each configured to receive a fastener,

the chassis comprises a third hole and a fourth hole,

when the sliding attachment bracket is in a first position in the pocket the first hole aligns with the third hole to allow the fastener to be received through the third hole into the first hole, and

when the sliding attachment bracket is in a second position the second hole aligns with the fourth hole to allow the fastener to be received through the fourth hole into the second hole, and the first hole is not aligned with the third hole when the second hole is aligned with the fourth hole.

2 . The mounting system of claim 1 , wherein the chassis comprises a mounting plate and an escutcheon and wherein the pocket is between the mounting plate and the escutcheon, and wherein the third hole and the fourth hole are formed in the mounting plate.

3 . The mounting system of claim 1 , wherein the fastener is a screw and wherein the first hole and the second hole are threaded.

4 . A mounting system for a door lock, the mounting system comprising:

a chassis;

a fastener, and

an attachment bracket configured to move between a first position and a second position relative to the chassis, wherein the attachment bracket comprises:

at least one attachment post extending along an attachment post axis,

a retaining plate affixed to the at least one attachment post,

a first hole, and

a second hole,

wherein the chassis further comprises at least one aperture through which the at least one attachment post passes, wherein the chassis further comprises a third hole and a fourth hole, wherein when the attachment bracket is in the first position the first hole aligns with the third hole to allow the fastener to be received through the third hole into the first hole, and wherein when the attachment bracket is in the second position the second hole aligns with the fourth hole to allow the fastener to be received through the fourth hole into the second hole.

5 . The mounting system of claim 4 , wherein the chassis further comprises a pocket configured to receive the retaining plate of the attachment bracket and inhibit rotation of the attachment bracket about the attachment post axis.

6 . The mounting system of claim 4 wherein the chassis further comprises a mounting plate and an escutcheon and wherein the attachment bracket is disposed between the mounting plate and the escutcheon.

7 . The mounting system of claim 4 , wherein the at least one attachment post is two attachment posts affixed to the retaining plate.

8 . The mounting system of claim 4 , wherein the attachment bracket is a first attachment bracket, wherein the mounting system further comprises a second attachment bracket comprising:

at least one second attachment post extending parallel to the attachment post axis, and

a second retaining plate affixed to the at least one second attachment post.

9 . The mounting system of claim 4 , wherein the fastener is a screw and the first hole and the second hole are threaded.

10 . The mounting system of claim 4 , wherein in the first position the attachment bracket is configured to remain in the first position, and wherein in the second position the attachment bracket is configured to remain in the second position.

11 . The mounting system of claim 4 , wherein the at least one attachment post comprises a first end portion affixed to the retaining plate and a second end portion, and wherein the second end portion is configured to receive a fastener.

12 . The mounting system of claim 4 , wherein the chassis further comprises a mounting plate and an escutcheon and wherein the attachment bracket is held between the mounting plate and the escutcheon, and wherein the mounting plate further comprises the at least one aperture configured to allow passage of the at least one attachment post therethrough and wherein the at least one aperture is configured to allow the attachment bracket to move between the first position and the second position while the at least one attachment post remains within the at least one aperture.

13 . The mounting system of claim 4 further comprising a fixed attachment post affixed to the chassis, the fixed attachment post being rigidly mounted to the door lock in a single position.
