Abstract

A lock unit with an escutcheon assembly to be mounted on a movable closure and a retainer clip to maintain the escutcheon assembly in an operative position on the movable closure. The escutcheon assembly defines a first shoulder. The clip has a biasing portion defining a second shoulder for bearing on the first escutcheon assembly shoulder and a third shoulder for bearing on a surface of a movable closure on which the escutcheon assembly is mounted with the escutcheon assembly in its operative position and the retainer clip and escutcheon assembly in assembled relationship. The biasing portion of the retainer clip is in compression between the second and third shoulders to positively maintain the escutcheon assembly in its operative position.

Claims

1. In combination:

a) a lock unit comprising;

an escutcheon assembly to be mounted on a movable closure member; and

a retainer clip to maintain the escutcheon assembly in an operative position on a movable closure member,

said escutcheon assembly defining a first shoulder and an axis,

said retainer clip having a biasing portion defining a second shoulder for bearing on the escutcheon assembly first shoulder and a third shoulder for bearing on a surface of a movable closure member on which the escutcheon assembly is mounted with the escutcheon assembly in its operative position and the retainer clip and escutcheon assembly in assembled relationship,

said biasing portion being in compression between the second and third shoulders to positively maintain the escutcheon assembly in its operative position on a closure member,

wherein the retainer clip has a base and first and second legs that project away from the base and define a U-shape with the base opening in one direction.

said first and second legs straddling the escutcheon assembly with the retainer clip and escutcheon assembly in assembled relationship,

wherein at least one of the retainer clip legs is V-shaped opening in a first direction and the base of the retainer clip has a U-shaped portion opening in the first direction,

said U-shaped portion defined by third and fourth legs with the third leg connecting to one of the first and second legs and the fourth leg defining a surface facing in a direction different from the one direction and a free edge facing in the first direction; and

b) a closure member to be mounted on a frame for movement between open and closed positions,

there being means cooperating between the closure member, retainer clip and escutcheon assembly to allow the retainer clip to be removably pressed into assembled relationship with the escutcheon assembly with the escutcheon assembly in an operative position on the closure member such that the surface on the fourth leg abuts to the closure member to limit rotation of the retainer clip around the axis of the escutcheon assembly.

2. The combination according to claim 1 wherein the one leg has a V-shaped bend therein with an apex defining the second shoulder.

3. The combination according to claim 2 wherein the one leg has first and second parts extending away from the apex and defining the V-shape and one of the first and second parts defines the third shoulder.

4. The combination according to claim 1 wherein the surface on the fourth leg is substantially flat and resides in a plane substantially at right angles to the length of the first and second legs.

5. The combination according to claim 1 wherein the retainer clip is defined as a single piece.

6. The combination according to claim 1 wherein the retainer clip is formed from a single metal piece.

7. The combination according to claim 1 wherein there is a tab projecting in cantilever fashion at the base of the retainer clip to facilitate prying of the retainer clip out of its assembled relationship with the escutcheon assembly.

8. The combination according to claim 1 wherein with the retainer clip pressed against the escutcheon assembly in an assembly direction into its assembled relationship, the free edge on the fourth leg abuts to a surface of the closure member facing oppositely to the first direction.
