Abstract

A nursery gate is provided with a pivoted latch. When the gate is swung to a closed position where it is co-planar with the keeper and hinge axis, the latch draw engages the keeper. At that time, a detent provided by the nose and the recess engages due to a spring movement of one of the part in the direction of the hinge axis. The gate is released for opening by a movement in the opposite direction against the spring so as to separate the nose and recess and allow the latch to pivot.

Claims

1. A nursery gate assembly comprising a structure with a gate vertical member and a post vertical member, a upper horizontal gate member secured to said gate vertical member and an upper horizontal post member secured to said post vertical member, said gate vertical member and said post vertical member having a gap therebetween, a means for securing the structure in an opening, a gate pivotally secured to said structure for movement between an open and a closed position, a latch means including a jaw pivotally secured to one of said gate vertical member and said post vertical member and engageable in a fixed locking position to retain said gate in said closed position;

a means for holding the jaw in said fixed locking position thereby maintaining said gate in said closed position;

a release member mounted to one of said post horizontal member and said gate horizontal member outside of said gap for releasing the jaw from said fixed locking position of said jaw to thereby allow the jaw to pivot on the gate so that the gate can be opened, and a detent carried on a rod, said rod extending vertically in the gate between upper and lower frame members and extending beyond the lower frame member for latching engagement with a threshold keeper.

2. A gate assembly according to claim 1 wherein the detent comprises a nose engageable in a recess in the jaw and arranged so that when the detent is disengaged and the jaw is turned, the detent abuts the jaw adjacent to the recess.

3. A gate assembly as claimed in claim 1 in which the detent comprises a recess engageable with a nose on the jaw and arranged so that when the detent is disengaged and the jaw is turned, the detent abuts a surface of the jaw adjacent to the nose.

4. A gate assembly as claimed in claim 1 wherein a surface of the jaw abutted by the detent has stop faces to limit angular movement.

5. A gate assembly as claimed in claim 1 wherein the jaw includes an arcuate recess and said second upright has a complementary arcuate cross-section to said arcuate recess.
