Abstract

A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

Claims (39)

1. A door assembly, comprising:

a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces;

a cylinder lock mounted to the second surface at the hole and providing a tab; and

a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface and including:

a main body that defines a central orifice;

a low-friction member received within the central orifice and defining an inner hole; and

an actuation mechanism extending from the low-friction member and engageable with the cylinder lock,

wherein the actuation mechanism comprises a head receivable within the inner hole and defining a recess, and a tab extension extending from the head, wherein the tab of the cylinder lock is receivable within the recess,

wherein actuating the cylinder lock rotates the actuation mechanism, and

wherein the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

2. The door assembly of claim 1 , wherein the main body is secured to the door within an interior of the door.

3. The door assembly of claim 1 , further comprising:

one or more reliefs defined in the main body; and

one or more mechanical fasteners extendable through the one or more reliefs and receivable by the cylinder lock to attach the cylinder lock to the main body.

4. The door assembly of claim 3 , further comprising a filler material received within the one or more reliefs on top of the one or more mechanical fasteners.

5. The door assembly of claim 4 , further comprising a sealant applied to the cylinder dry lock assembly as mounted to the door at the hole, wherein the sealant covers at least one of i) mechanical fasteners that couple the main body to the door, ii) the filler material, or iii) a portion of the low-friction member.

6. The door assembly of claim 1 , further comprising an exit device mounted to the first surface and including a latch housing and a latch pivotably mounted to a side of the latch housing,

wherein the tab extension is receivable within a receiver provided within the latch housing, and wherein actuating the cylinder lock rotates the actuation mechanism and thereby causes the latch to actuate.

7. A cylinder dry lock assembly, comprising:

a main body mountable to a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, the main body being mountable within an interior of the door at the hole and defining a central orifice;

a low-friction member receivable within the central orifice and defining an inner hole; and

an actuation mechanism extending from the low-friction member and engageable with a cylinder lock mountable to the second surface, the actuation mechanism comprising:

a head receivable within the inner hole and defining a recess; and

a tab extension extending from the head, wherein the cylinder lock provides a tab receivable within the recess,

wherein actuating the cylinder lock rotates the actuation mechanism, and

wherein the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces through the hole.

8. The cylinder dry lock assembly of claim 7 , wherein the main body defines a raised shoulder configured to be received at the hole within the interior of the door.

9. The cylinder dry lock assembly of claim 7 , wherein the low-friction member is selected from the group consisting of a sealed bearing, a bushing, a bushing assembly, and any combination thereof.

10. The cylinder dry lock assembly of claim 7 , further comprising a shelf defined within the central orifice, wherein the low-friction member engages the shelf when received within the central orifice.

11. The cylinder dry lock assembly of claim 7 , wherein the tab extension defines one or more breakaway points.

12. A method of assembling a door assembly, comprising:

mounting a cylinder dry lock assembly within an interior of a door at a hole defined in the door, the hole extending between opposing first and second surfaces of the door, and the cylinder dry lock assembly including:

a main body that defines a central orifice;

a low-friction member receivable within the central orifice; and

an actuation mechanism extending from the low-friction member, wherein the actuation mechanism defines a recess; and

mounting a cylinder lock to the second surface of the door at the hole and thereby engaging the actuation mechanism,

wherein the cylinder lock provides a tab and mounting the cylinder lock to the second surface of the door comprises inserting the tab of the cylinder lock into the recess of the actuation mechanism,

wherein actuating the cylinder lock rotates the actuation mechanism, and

wherein the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces through the hole.
