Abstract: A cage structure consists of a roof member and base member each having a bore at each of its corners, and a series of wall members releasably securable together and to the roof and base members to form an enclosure. Each wall member also has a bore at each of its corners. Three way connectors or joints releasably connect the corners of the adjacent three members at each corner of the cage. Each three way connector has three arms which engage in the respective bores of the three members at that corner to secure the members together, so that a major part or all of the connector is concealed when the cage is assembled.

Abstract: A door latch assembly for holding a door in a closed position comprises a latch housing for mounting in the side of a door frame, and a latch pin for mounting on the corresponding side of a door to project towards the latch housing. The latch housing has an opening for receiving the latch pin as the door is closed, and a latch member in the housing is movable between a first, latching position in which the latch pin is held in the housing and a second, release position in which the latch pin is released and pushed out of the housing in a door opening direction. An actuator projects out of the housing for moving the latch member into the second position. The latch member is biased towards its latching position.
