LATCHING DEVICES FOR GATES AND DOORS |
摘要 |
<p>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.</p> |
