Abstract:
1. A device for arresting movement of a rail accommodated within a channel, wherein the device comprises: a slide surface located in one of the rail or channel and inclined in relation to an opposing side wall of the other of the rail or channel; a slide member arranged to slide along the slide surface between an extended position and a retracted position; a resilient member which biases the slide member along the slide surface towards the extended position and into abutment with the side wall; and a manually operable button coupled to the slide member to enable user-operated movement of the slide member towards the retracted position, wherein movement of the channel in relation to the rail in a first direction causes friction between the slide member and the side wall to push the slide member along the slide surface and towards the retracted position, wherein movement of the channel in relation to the rail in a second direction, opposite to the first direction, causes friction between the slide member and the side wall to push the slide member along the slide surface towards the extended position, and wherein the device further comprises a lock mechanism for holding the slide member in the retracted position.
