Latching devices for gates and doors
First Claim
1. A latching device for latching, in a predetermined position, two members which are otherwise moveable relative to one another, the latching device comprising:
- a retaining element adapted to be mounted to a first of the members;
a mounting structure arranged to be mounted on a second of the members;
a latch arm mounted on the mounting structure and arranged in use, when in an engaged position, to engage with the retaining element to prevent relative movement of the members, the latch arm being displaceable to a disengaged position so that the members may be moved apart;
a first operating mechanism for displacing the latch arm to the disengaged position, the first operating mechanism including a first actuator manipulatable by a user to displace the latch arm to the disengaged position, the first actuator being positionable in use at a first height accessible by a standing adult user, anda second operating mechanism for displacing the latch arm to the disengaged position, the second operating mechanism including a second actuator manipulatable by an adult user to displace the latch arm to the disengaged position, the second actuator being positionable in use at a second height, lower than the first height, and accessible by a seated adult, such as a disabled person in a wheelchair, wherein the second actuator requires a key for operation, and wherein the second actuator includes a push button for operation.

Abstract
A latching device (1) particularly for installation such as swimming pool gates may have an automatic magnetic latch with a child resistant device to control access. The child resistant device may include an operating handle (10) at an elevated location to be out of the reach of the child and an alternative operating device (11) is provided at a lower location with child resistance provided typically by a push button arrangement (12) acting through a cam and cam follower to raise a latching arm (3) against the biasing to the latching position. A simple pronged key (16) for a pushing action can be provided, but another aspect consists in a mechanically actuatable key pad (20) which can readily be operated by an adult even in a wheelchair, but which is resistant to child actuation. For example, a selected two of eight buttons may be required to be depressed to permit the key to actuate the push button.

13. A latching device for latching, in a predetermined position, two members which are otherwise moveable relative to one another, the latching device comprising:
-
a retaining element adapted to be mounted to a first of the members; a mounting structure arranged to be mounted on a second of the members; a latch arm mounted on the mounting structure and arranged in use, when in an engaged position, to engage with the retaining element to prevent relative movement of the members, the latch arm being displaceable to a disengaged position so that the members may be moved apart; a first operating mechanism for displacing the latch arm to the disengaged position, the first operating mechanism including a first actuator manipulatable by a user to displace the latch arm to the disengaged position, the first actuator being positionable in use at a first height accessible by a standing adult user; a second operating mechanism for displacing the latch arm to the disengaged position, the second operating mechanism including a second actuator manipulatable by an adult user to displace the latch arm to the disengaged position, the second actuator being positionable in use at a second height, lower than the first height, and accessible by a seated adult, such as a disabled person in a wheelchair; the mounting structure including a connector operatively associated with the first and second operating mechanisms, and the connector and latch arm being arranged to be substantially vertically upward displaceable to permit unlatching and relative movement between the gate and gate post; and the second operating mechanism cooperates with the second actuator so that displacement of the second actuator is by motion in a substantial horizontal direction to cause displacement upwardly of the connector and latch arm. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

- 26. A key for operating a locking mechanism, wherein the key is arranged to be normally set to a disabled state where it cannot be used and capable of adult manipulation to an enabled state where it can be used, the key including a security means, operation of which by adult manipulation sets the key to the enabled state.
