Cross-Reference to Related Application

[0001] This application claims the benefit of U.S. Provisional Application Serial Nos. 62/968,731, filed January 31, 2020; and 62/904,101, filed September 23, 2019, the disclosures of which are hereby incorporated by reference in their entireties.

Technical Field

[0002] This disclosure relates to the field of door locks. More particularly, this disclosure relates to door locksets for sliding doors.

Background

[0003] Sliding interior doors (known as “bam doors”), have become very popular recently. Such sliding doors are often hung using a roller bracket and will slide along a rail mounted above a doorway, e.g., either inside or outside the doorway. Traditional locks provide a privacy locking function on an interior sliding door (bathroom, bedroom, home office, TV room, etc.). Although sliding doors are popular for aesthetic reasons, such traditional locks are not suitable for use with sliding doors. Still further, because sliding doors may be hung from rails positioned either inside or outside of the room in which a privacy locking function is desired, any existing locking solutions may not be suitable for all mounting possibilities.

[0004] Existing solutions have a number of shortcomings. For example, in some instances, locking mechanisms can only lock the door on one side, such as in the case of a hook-and-eye. Still further, in some instances, locks can only be installed either on the outside or the inside of the door exclusively, and therefore separate solutions are required for each possible installation configuration, leading to consumer confusion at a point of sale.

[0005] Additionally, such traditional sliding door locks having privacy lock features lack the ability to be unlocked from the “other” (outside) side of the door in the case of an emergency situation (e.g., a child not able to unlock the door from within the room in which privacy is sought). Summary

[0006] The present disclosure relates generally to door locks, specifically for sliding doors. Generally, a sliding door lockset as described can be installed on a sliding door located on the interior or exterior of a room.

[0007] In one example of the present disclosure, a door lockset for a sliding door is described. The door lockset includes a latch assembly, a plunger, a plunger retention assembly, and a secondary unlock feature. The latch assembly has a first end and a second end. The plunger is positioned at least partially within the latch assembly. The plunger is movable between an extended position and a retracted position relative to the second end of the latch assembly. The plunger retention assembly includes a first end having a recess, a second end, and an actuation member positioned at least partially within the plunger retention assembly. The plunger is configured to engage the recess in the extended position.

[0008] In another example of the present disclosure, a door lockset for a sliding door is described. The door lockset includes a latch assembly, a plunger, a handle, and a plunger retention assembly. The latch assembly has a first end and a second end. The plunger is positioned at least partially within the latch assembly. The plunger is movable between an extended position and a retracted position relative to the second end of the latch assembly. The handle is located on a first end of the plunger and is in communication with the plunger to move the plunger between the retracted position and the extended position. The plunger retention assembly includes a first end having a recess, a second end having a stationary plate, and an actuation member positioned at least partially within the plunger retention assembly. The plunger is configured to engage the recess in the extended position.

[0009] In yet another example of the present disclosure, an alternative door lockset for a sliding door is described. The door lockset includes a latch assembly, a plunger, and a plunger retention assembly. The latch assembly has a first end and a second end. The plunger is positioned at least partially within the latch assembly. The plunger is movable between an extended position and a retracted position relative to the second end of the latch assembly. The plunger retention assembly includes a first end having a recess, a second end, and an actuation member. The actuation member comprises a rod and is positioned at least partially within the plunger retention assembly. The plunger retention assembly includes a pushbutton on the second end. The pushbutton is connected to the rod extending through the plunger retention assembly. The rod is configured to engage the plunger to move the plunger between the retracted position and the extended position. The plunger is configured to engage the recess in the extended position.

[0010] In yet another example of the present disclosure, a plunger retention assembly for a sliding door is disclosed. The plunger retention assembly includes a first body positioned at a first end and a second body positioned at a second end. The first body and the second body are connected to one another to form an interior of the plunger retention assembly. The plunger retention assembly includes a plunger positioned at least partially within the interior. The plunger at least partially extends a user definable distance from the first end. The plunger retention assembly includes a pushbutton movably positioned at the second end. The pushbutton is connected to the plunger within the interior. Upon movement of the pushbutton into the interior, the plunger extends further from the first end.

The latch plunger 510 is configured to selectably interface with the plunger 410 of the plunger retention assembly 420 and extend from the first end 504 and/or the second end 506 of the latch assembly 502. When locked, the latch plunger 510 extends into the interior 418 of the plunger retention assembly 420. When unlocked, the latch plunger 510 does not extend into the interior 418 of the plunger retention assembly 420.

[0094] FIG. 17 shows a partially exploded view of the latch assembly 502 with the first and second covers 512, 514 removed from a main body 516 of the latch assembly 502. The main body 516 includes a block 518 attached thereto. The block 518 functions similar to the block 302 described above. The block 518 is configured to interface with an aperture 521 of the first cover 512 as the latch plunger 510, and therefore the main body 516, moves longitudinally within the first and second covers 512, 514. The block 518 is connected to a connecting member 520 and the block 518 moves the connecting member 520 within a slot 522 to selectively engage a guide member 524. In some examples, movement of the main body 516 is spring loaded with the help of a spring 505 that interfaces with at least one of the first and second covers 512, 514 and the main body 516. [0095] FIG. 18 shows a side view of the main body 516 of the latch assembly 502. In some examples, the view is the top view of the main body 516 and, in other examples, the view is the bottom view of the main body 516. The block 518 is not shown for illustration purposes, but the guide member 524 moves within the slot 522, much like the guide member 306 described above, as the latch plunger 510 moves longitudinally within the latch assembly 502. As the guide member 524 and connecting member 520 go into and out of engagement with one another, the latch assembly 502 is moved between an extended position and a retracted position. The latch assembly 502 operates in a similar fashion to the latch assembly 102, specifically regarding the movement of the connecting member 304 and guide member 306 as described above.

[0096] FIG. 19 shows the plunger retention assembly 420 being installed on the door A. The outer body 406 is first positioned within a bore 413 of the door A and the outer body 406 is positioned so that the first end 428 aligns with the latch plunger 510 of the latch assembly 502 so that the latch plunger 510 is positioned to enter the interior 418 of the plunger retention assembly 420. If adjustment is needed, the user can either rotate the outer body 406 clockwise to reduce the distance the outer body 406 extends from the door jamb side 403 of the door A, or rotate the outer body 406 counter-clockwise to increase the distance the outer body 406 extends from the doorjamb side 403 of the door A. This is made possible because the inner body 408 is threaded into the outer body 406, and therefore rotation of the outer body 406 extends or retracts the overall length of the plunger retention assembly 420.

[0097] The outer body 406 is shown to contain the components of the plunger retention assembly 420, except for the flange 402 and the flange seal 404. When the outer body 406 is at the desired position within the bore 413, the flange 402 is positioned around the outer body 406 until the flange 402 is positioned immediately adjacent the doorjamb side 403 of the door A. The flange seal 404 is then positioned around the outer body 406 and positioned immediately adjacent the flange 402.

[0098] FIG. 20 shows the further optional step of installing and positioning the plunger retention assembly 420 on the door A. Once the flange 402 and flange seal 404 are positioned around the outer body 406, the user rotates the outer body 406 (e.g., clockwise) to securely fasten the plunger retention assembly 420 with the door A. By rotating the outer body 406 clockwise when the flange 402 is positioned against the doorjamb side B of the door, the plunger retention assembly 420 tightens against the door A between the flange 402 on the doorjamb side B of the door A and the inner body 408 of the user side 401 of the door A.

[0099] FIG. 21 shows the proper positioning of the plunger 410 of the plunger retention assembly 420 and the position of the latch plunger 510 when the latch plunger 510 is retracted. Specifically, the latch plunger engagement member 424 of the plunger 410 is configured to selectably extend and interface with the retracted plunger 510 of the latch assembly 502.

[00100] FIG. 22 shows the improper positioning of the plunger 410 of the plunger retention assembly 420 and the position of the latch plunger 510 when the latch plunger 510 is retracted. Specifically, the latch plunger engagement member 424 of the plunger 410 does not interface with the retracted plunger 510 of the latch assembly 502. To adjust the distance the plunger 410 extends, the plunger 410 is rotated into, or out of, the plunger receiver 412.

[00101] FIG. 23 shows adjusting the length of the plunger 410 during installation. In some examples, the clip 414 can be used to ensure the plunger 410 does not accidently move too far into the plunger receiver 412. Upon depressing the pushbutton 432/unlock feature 435 on the user side 401 of the door A, the user installs the clip 414 into the groove 423 on the rod 422 of the plunger 410. In some examples, the plunger 410 is partially rotated counter-clockwise to allow for the clip 414 to be installed. Once the plunger 410 is rotated clockwise so that the clip interfaces with plunger receiver, as shown in FIG. 24, the clip 414 will not pass into the plunger receiver 412 and the clip 414 will prevent the rod 422 from traveling further into the plunger receiver 412. This positioning is also shown in FIG. 15.
