Abstract

An electric door strike assembly includes a housing and at least one keeper arm. The housing has an opening for admission and retraction of a door latch. The at least one keeper arm has a latch portion and is mounted on the housing. The at least one keeper arm is movable between a closed position, where the opening is occluded by the latch portion, and an open position, where the door latch may be released from the opening. The latch portion may include a bifurcated member having inside and outside legs arranged in spaced parallel relation so as to define a gap therebetween. The gap is configured to receive a latch plate of an interlocking latch mechanism when the at least one keeper arm is in the closed position.

Claims

1. An electric strike assembly, comprising:

a) a housing having an opening for admission and retraction of a door latch; and

b) at least one keeper arm having a latch portion, wherein the at least one keeper arm is mounted on the housing, and movable between a closed position wherein the opening is occluded by the latch portion and an open position wherein the door latch may be released from the opening,

wherein the latch portion comprises a first leg,

wherein an edge of said first leg is configured to receive a latch plate of a latch mechanism therein when the keeper arm is in the closed position.

2. The electric strike assembly in accordance with claim 1, wherein said latch portion comprises a second leg so as to define a gap said first leg and said second leg and wherein the gap is configured to receive said latch plate when the at least one keeper arm is in the closed position.

3. The electric strike assembly in accordance with claim 1 wherein a front wall of said first leg lie along a first longitudinal plane and wherein a back wall of said first leg lie along a second plane which is disposed at an angle to the first longitudinal plane whereby the back wall define a ramped surface.

4. The electric strike assembly in accordance with claim 1 comprising a second keeper arm having a second latch portion, wherein said second keeper arm is mounted on the housing, and movable between a closed position wherein the opening is occluded by the latch portion and an open position wherein the door latch may be released from the opening,

wherein said second latch portion comprises a first leg,

wherein an edge of said first leg of said second latch portion is configured to receive said latch plate of said latch mechanism therein when said second keeper arm is in the closed position.

5. The electric strike assembly in accordance with claim 4 wherein the first leg of the first keeper arm includes a first step and wherein the first leg of the second keeper arm includes a second step which is complementary to the first step whereby the first and second steps interlock with one another when the first and second keeper arms are in the closed position.

6. The electric strike assembly in accordance with claim 1 wherein said latch mechanism is an interlocking latch mechanism.
