Abstract
A security transfer device (1) for mounting on a side wall of a building such as a bank, for example, for transferring valuables between a vehicle and the building includes a duct (2) slidably mounted in a housing (3) secured in a wall (23) of the building and movable between a retracted stored position within the housing (3) and an extended in-use position projecting outwardly of the housing (3). A releasable ratchet mechanism (4) extends between the duct (2) and housing (3) . When engaged the ratchet mechanism only permits outward movement of the duct (2), thus preventing the duct (2) from being pushed back into the housing from outside the building. A lockable door (12) closes an inner end of the housing (3). The duct (2) is also closed at it's rear end (19) by a lockable security door (20).
Claims20
A security transfer device for transferring valuables between a building and a vehicle each having a transfer opening in a face thereof comprising:
- a support frame for mounting in one of said transfer openings:
- a duct slidably mounted on the support frame and movable through said one of said openings between a retracted stored position and an extended in-use position for abutment against the face surrounding the other of said openings;
- a releasable stop means mounted between said duct and said support frame and being operable to prevent unauthorized retraction of said duct from an extended position toward said retracted position;
- a lockable security first closure member mounted within said duct for movement between an open position and a closed position;
- and
- automatically operated releasable locking means mounted on said duct for movement relative to said duct and said fist closure member and engageable with said first closure member for automatically locking said first closure member in said closed position when said duct is in said retracted stored position and automatically releasing said first closure member when said duct is at a predetermined distance outwardly of said retracted stored position in the direction of said extended position.
