Abstract:
A mounting for a computer accessory such as a hard disc drive comprises a tray (2) for accommodating the accessory (1) which can be inserted into a mounting bay in the computer against the bias of a pair of springs (4). The tray (2) carries a bezel member (7) movable along the insertion path independently of the tray to latch or unlatch the tray in place, using latching members (6) in association with latching tracks formed in the bezel, by way of a push-push action.
Abstract:
Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position. When a blade is to be removed, the clamping apparatus needs only to be moved to its unclamped position by manually rotating the outer sleeve or collar, and the blade is normally ejected from the mechanism by contact with the blade shoulders as it reaches its unclamped position.
