Abstract

A gate assembly is provided for positioning in an opening through which selective entry is required. The gate assembly includes barrier means mountable directly or indirectly to one or more surrounding surfaces defining said opening, and hinge means to allow said barrier means to be movable relative to said surrounding surfaces in use between a closed condition, wherein the opening is closed, to an open condition, wherein the opening is open. The hinge means are arranged so that the barrier means and/or hinge means has an axis of pivot which is at an acute angle to a vertical axis. Resilient biasing means are associated with the hinge means to help bias the barrier means from the open condition to the closed condition in use. The resilient biasing means act in a direction along a substantially horizontal axis or along an axis substantially transverse or perpendicular to the axis of pivot of the barrier means and/or hinge means.

Claims

1. A gate assembly for positioning in an opening through which selective entry is required, said gate assembly including barrier means mountable directly or indirectly to one or more surrounding surfaces defining said opening and hinge means to allow said barrier means to be movable relative to said surrounding surfaces in use between a closed condition, wherein the opening is closed, to an open condition, wherein the opening is open, said hinge means arranged so that the barrier means and/or hinge means has an axis of pivot which is at an acute angle to a vertical axis, resilient biasing means associated with the hinge means to help bias the barrier means from the open condition to the closed condition in use, characterised in that the resilient biasing means act in a direction along a substantially horizontal axis or along an axis substantially transverse or perpendicular to the axis of pivot of the barrier means and/or hinge means.

2. A gate assembly according to claim 1 wherein the gate assembly automatically moves from an open position to a closed position once a user release their grip on the barrier means in use.

3. A gate assembly according to claim 1 wherein the hinge means includes an upper hinge arrangement provided at, adjacent or towards a top of the barrier means, a lower hinge arrangement provided at, adjacent or towards a base of the barrier means and the axis of pivot of the upper and lower hinge arrangements is at an acute angle to the vertical axis.

4. A gate assembly according to claim 1 wherein the acute angle is between 1-10 degrees.

5. A gate assembly according to claim 3 wherein the resilient biasing means is provided with or associated with at least the upper hinge arrangement.

6. A gate assembly according to claim 1 wherein the resilient biasing means and/or an intermediate member is provided with or associated with a frame element or wall to which the hinge means or at least part of an upper hinge arrangement is pivotably mounted to in use.

7. A gate assembly according to claim 6 wherein the intermediate member is slidably mounted in a housing associated with the frame element or wall and has a first end in engagement with the barrier means, hinge means or upper hinge arrangement and a second end in engagement with the resilient biasing means.

8. A gate assembly according to claim 7 wherein the first end of the intermediate member is curved, angled, bevelled, chamfered and/or is a cam surface.

9. A gate assembly according to claim 7 wherein the first end of the intermediate member engages in a slot, recess or channel defined in the barrier means, hinge means or upper hinge arrangement.

10. A gate assembly according to claim 7 wherein the resilient biasing means biases the intermediate member towards the barrier means and pivotal movement of the barrier means in use causes sliding movement of the intermediate member against a biasing force of the resilient biasing means.

11. A gate assembly according to claim 7 wherein the upper hinge arrangement has a first hinge element including a pivot pin or protrusion member which is pivotally or rotatably mounted in a recess, channel or aperture provided on a second hinge element including a recess, the first end of the intermediate engaging with an outer surface of the first hinge element.

12. A gate assembly according to claim 1 wherein a handle mechanism is provided on the gate assembly, said handle mechanism including latch means movable with respect to latch receiving means between a latched position, wherein the latch means is engaged with or located in the latch receiving means, and an unlatched position, wherein the latch means is disengaged from or removed from the latch receiving means, and user actuation means for allowing a user to actuate said latch means in use, and wherein actuation of said user actuation means enables said latch means to undergo movement on movement of the handle mechanism, barrier means or gate assembly relative to the latch receiving means.

13. A gate assembly according to claim 12 wherein the latch means is arranged to undergo rotational and/or pivotal movement on movement of the handle mechanism, barrier means or gate assembly relative to the latch receiving means.

14. A gate assembly according to claim 12 wherein locking means are associated with the latch means and actuation of the user actuation means moves the locking means from a locked position, wherein movement of the latch means is substantially prevented, to an unlocked position, wherein movement of the latch means is enabled.

15. A method of using a gate assembly for positioning in an opening through which selective entry is required, said gate assembly including barrier means mountable directly or indirectly to one or more surrounding surfaces defining said opening, said method including the steps of moving said barrier means via hinge means from a closed condition, wherein the opening is closed, to an open condition, wherein the opening is open, releasing said barrier means when in the closed position to allow automatic closure of the barrier means, said hinge means arranged so that the barrier means and/or hinge means has an axis of pivot which is at an acute angle to a vertical axis, resilient biasing means associated with the hinge means to help bias the barrier means from the open condition to the closed condition in use, and the resilient biasing means acting in a direction along a substantially horizontal axis or along an axis substantially transverse or perpendicular to the axis of pivot of the barrier means and/or hinge means.
