Abstract

A gate assembly including a frame for positioning in an opening through which selective entry is required. A barrier is mountable on the frame via a hinge and the barrier is movable relative to the frame between a closed position, wherein the opening is closed, to an open position, wherein the opening is open. An automatic closure mechanism is provided for moving the barrier from the open position to the closed position without user intervention. The automatic closure mechanism is associated with the hinge and includes at least two ramps or inclined surfaces on which at least part of the gate travels when moving between the open and closed positions.

Claims

1. A gate assembly comprising,

a frame for positioning in an opening;

a barrier mountable on said frame via an upper hinge a and lower hinge, and said barrier movable relative to said frame between a closed position, wherein the opening is closed, to an open position, wherein the opening is open; and

an automatic closure mechanism provided for moving the barrier from the open position to the closed position without user intervention,

wherein the automatic closure mechanism is a part of the lower hinge and includes at least two ramps or inclined surfaces upon which a base of the barrier travels as the barrier moves between the open and closed positions, and

wherein the base of the barrier is disposed between the at least two ramps or inclined surfaces when the barrier is in the closed position, and

wherein a user initially lifts the barrier in an upwardly direction and raises the base of the barrier beyond at least one of the inclined surfaces or ramps before rotating the barrier to move the barrier from the closed position to the open position.

2. A gate assembly according to claim 1, wherein the base of the barrier is engageable with on at least one of the ramps or inclined surfaces.

3. A gate assembly according to claim 1, wherein the inclined surfaces or ramps each have a first end adjacent an upright member of said frame and a second end spaced from said upright frame member, each of the second ends having a lower height than each of the first ends.

4. A gate assembly according to claim 1, wherein the at least two ramps or inclined surfaces define a recess in which the base of the barrier is disposed when the barrier is in the closed position.

5. A gate assembly according to claim 1, wherein the at least two ramps or inclined surfaces define a recess therebetween.

6. A gate assembly according to claim 1, wherein one of the upper or lower hinges includes a hinge pin.

7. A gate assembly according to claim 1, wherein the upper and lower hinges are provided on a first side of the barrier and a latch for latching the barrier to the frame is provided on a second side of the barrier.

8. A gate assembly according to claim 7, wherein the latch comprises a barrier latch and a frame latch, wherein the barrier latch is substantially aligned with the frame latch when the barrier is in the closed position.

9. A gate assembly according to claim 7, wherein the latch includes a latch element which is slidably movable relative to a recess defined in a keep housing between a latched position, wherein the latch element is located in the recess of the keep housing and an unlatched position, wherein the latch element is spaced from the recess of the keep housing.

10. A gate assembly according to claim 9, wherein the latch element is resiliently biased to the latched position.

11. A gate assembly according to claim 9, wherein the latch element is moved into the unlatched position before the barrier is moved from the closed position to the open position.

12. A gate assembly according to claim 1, wherein the gate assembly is a child safety gate.

13. A method of using a gate assembly, said method comprising:

positioning a frame in an opening;

mounting a barrier on said frame via a lower hinge and an upper hinge; and

moving said barrier relative to said frame between a closed position, wherein the opening is closed, and an open position, wherein the opening is open, and

wherein an automatic closure mechanism is provided for moving the barrier from the open position to the closed position without user intervention, the automatic closure mechanism is part of the lower hinge and includes at least two ramps or inclined surfaces upon which a base of the barrier travels when the barrier moves between the open and closed positions, and wherein the barrier rests between the at least two ramps or inclined surfaces when the barrier is in the closed position, and

wherein when moving the barrier from the closed position the open position, the user initially lifts the barrier in an upwardly direction and raises the barrier out from between the at least two ramps or inclined surfaces.
