Abstract

A cupboard door latch assembly 1 is disposed within the lower part of a kitchen cupboard 2, having a door 3 and base 4. The latch assembly 1 comprises a mounting plate 5 placed on the rear surface 6 of the door 3 and secured thereto by screws (not shown). A latch member 8 is carried by, and is pivotable relative to, the mounting plate 5, a keeper 9 is placed on the upper surface 10 of the cupboard base 4, spring means 15 are provided for urging the latch member 8 into door-locking engagement with the keeper 9, and actuating means 16 operable from outside the door 3 are provided for overcoming the effect of the spring means 15 and for pivoting the latch member 8 out of door-locking engagement with the keeper 9. The latch member 8 and mounting plate 5 comprise a one-piece component of plastics material. The member 8 and the plate 5 are joined by a thin web 17 which can flex to allow pivotable movement of the member 8 relative to the plate 5. <IMAGE>

Description

IMPROVEMENTS IN OR RELATING TO DOOR LATCH ASSEMBLIES This invention relates to latch assemblies and is particularly concerned with latch assemblies for use with cupboards.
The invention has particular application to kitchen cupboards employed in buildings constructed in earthquake zones, and is designed, in the event of an earthquake, to maintain cupboard doors closed and so prevent the contents of the cupboards from spilling out and causing injury and damage.
According to the invention, a cupboard door latch assembly comprises a mounting plate for placement on the rear surface of the door, a latch member carried by, and pivotable relative to, the mounting plate, a keeper for placement within the cupboard, spring means for urging the latch member into door-locking engagement with the keeper, and means operable from outside the door for overcoming the effect of the spring means and for pivoting the latch member out of door-locking engagement with the keeper.
The means operable from outside the door preferably comprise means operable by a pulling action.
The invention also comprises a compartment, such as a cupboard, provided with the latch assembly.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, wherein: Figure 1 is a fragmentary side view, in section, of the lower part of a cupboard; and Figures 2 and 3 are, respectively, end views in the directions of arrows II and III of Figure 1, with the cupboard door removed.
With reference to Figure 1, a cupboard door latch assembly 1 is shown within the lower part of a kitchen cupboard 2, having a door 3 and base 4.
The latch assembly 1 comprises a mounting plate 5 placed on the rear surface 6 of the door 3 and secured thereto by screws (not shown) located by holes 7. (Figures 2 and 3.) The assembly 1 further comprises a latch member 8 carried by, and pivotable relative to, the mounting plate 5, a keeper 9 placed on the upper surface 10 of the cupboard base 4, spring means 15 for urging the latch member 8 into door-locking engagement with the keeper 9, and actuating means 16 operable from outside the door 3 for overcoming the effect of the spring means 15 and for pivoting the latch member 8 out of door-locking engagement with the keeper 9.
The latch member 8 and mounting plate comprise a one-piece component of plastics material. Member 8 and plate 5 are Joined by a thin (1.0 mm) web 17 which can flex to allow pivotable movement of the member 8 relative to the plate 5.
The upper end of the latch member 8 extends upwardly and inwardly, (relative to the cupboard interior) at an angle of about 22O. This angle can be varied in order to suit the degree of lift required on the latch member.
The lower end of the latch member 8 carries a downwardly-extending projection 18 which, in the door-engaging position shown of the latch assembly 1, engages with a step 19 formed in the keeper 9.
The keeper 9, which is secured to the cupboard base 4 by screws, (not shown), has a rounded leading edge 20.
The actuating means 16 comprise a knob 25, an actuating rod 26 extending between the knob 25 and a retaining head 27, a retaining washer 28 and a compression spring which serves as the spring means 15.
The rod 26 extends with clearance through aligned apertures in the door 3, mounting plate 5 and latch member 8. The aperture in the latch member 8 comprises a slot 21. The compression spring 15 is disposed between the mounting plate 5 and latch member 8.
In operation, when the door 3 is subjected to a closing movement, the projection 18 of the latch member 8 moves upwardly over the rounded leading edge 20 of the keeper 9 to fall behind the step 19 and engage therewith. The latch member 8 pivots or flexes to allow this.
The latch member 8 is retained in this door-locking engagement with the keeper 9 by the effect of the spring means 15.
Should an earthquake occur, or the cupboard 2 be otherwise subjected to vibration, the spring means 15 retain the latch member 8 and keeper 9 in positive interengagement.
To open the cupboard door 3, one hand is first placed on the door, so as to keep It closed, and then the other hand is used to grasp the knob 25 and to pull it away from the door. This pulling action causes the latch member 8 to pivot in an anti-clockwise direction, (as viewed in Figure 1), whereby the latch member projection 18 and the keeper 9 disengage.
Any attempt to pull the knob 25 away from the door 3 without initially restraining the door, will not result in opening of the door, as the door 3 and the latch member 8 will move together, without pivotal movement of the latter. This is because the height of the web 17 above the keeper 9 is insufficient to overcome the couple exerted by the spring 15.
The latch assembly 1 is preferably mounted in the lower region of the kitchen cupboard 2, as shown, where door opening knobs are usually situated.
The hole in the door 3 in which the rod 26 is movable may comprise an existing hole for an original door knob.
The invention has application to cupboards carried by caravans, (trailers), and may also be used as a child-proof latch.

Claims (13)

1. A cupboard door latch assembly comprising a mounting plate for placement on the rear surface of the door, a latch member carried by, and pivotable relative to, the mounting plate, a keeper for placement within the cupboard, spring means for urging the latch member into door-locking engagement with the keeper, and means operable from outside the door for overcoming the effect of the spring means and for pivoting the latch member out of door-locking engagement with the keeper.
2. A latch assembly as claimed in Claim 1, wherein the means operable from outside the door comprise means operable by a pulling action.
3. A latch assembly as claimed in Claim 1 or 2, wherein the latch member and mounting plate comprise a one-piece component.
4. A latch assembly as claimed in Claim 3, wherein the latch member and mounting plate are joined by a web which can flex to allow pivotable movement of the latch member relative to the mounting plate.
5. A latch assembly as claimed in Claim 3 or 4, wherein the one-piece component is of plastics material.
6. A latch assembly as claimed in any one of Claims 1 to 5, wherein the upper end of the latch member, when the assembly is in place within the cupboard, extends upwardly and inwardly (relative to the cupboard interior).
7. A latch assembly as claimed in Claim 6, wherein the upper end of the latch member extends upwardly and inwardly, (relative to the cupboard interior), at an angle of about 220.
8. A latch assembly as claimed in any one of Claims 1 to 7, wherein the lower end of the latch member carries a downwardly-extending projection, which in the door-engaging position of the assembly, engages with a step formed in the keeper.
9. A latch assembly as claimed in any one of Claims 1 to 8, wherein the height of the latch member mounting pivot point is disposed above the keeper to an extent insufficient to overcome a couple exerted on the latch member by the spring means.
10. A latch assembly as claimed in any one of Claims 1 to 9, wherein the means operable from outside the door comprise means operable by a pulling action.
11. A latch assembly as claimed in Claim 10, wherein the means operable from outside the door comprise a knob, an actuating rod extending from the knob, through the mounting plate and latch member to a retaining head disposed on the remote side of the latch member and a compression spring disposed between the mounting plate and the latch member, the compression spring comprising said spring means.
