Abstract: A driven part can be pivotably mounted to the door frame so that, in a starting position, it engages a driving part fixed to the leaf frame in order to fix the position of the door leaf with respect to the door frame. An electromagnetic brake generates a moment to retain the driven part in the starting position when electrical current is supplied, and allows the driven part to pivot from the starting position when electrical current is not supplied. The driven part is held in the starting position when the driven part returns to the starting position and no moment is generated by the electromagnetic brake.

Elongated, vertically oriented anti-jamming panels are provided in the doorway, which rotate about a vertical axis so that a lateral edge of the panel projects into the doorway and rotates in a direction so as to eject into the vestibule an object or person obstructing the closure of the door.

Abstract: The security method and apparatus relates to an electronically controlled latching mechanism which is adapted for use with a closure disposed on a vestibule. The closure is used to seal or close off a passageway or entrance between the vestibule and a protected or secured area. A security unit generates a signal which drives the latching mechanism from a latched to an unlatched position whenever an access control circuit generates an enablement signal. The enablement signal is generated whenever the vestibule is sealed and the weight of the person or persons within the vestibule, as determined by an electronic scale, compares with a predetermined weight value. A closure switch senses when the vestibule is closed, and a weight sensing mechanism senses the weight of a person or person disposed within the vestibule.

Abstract: This security entrance is of the box-type with interlocked doors, and comprises an armoured vestibule having one door communicating with the bank and one door communicating with the exterior; a third door can be opened into a discharge space separate from the bank. This third door is controlled by a metal detector of known type.

Abstract: A manually actuable lock is disposed on the inside of an outside door leading to a vestibule. The lock, when manually actuated from inside the vestibule only, throws a dead bolt for a pre-determined period of time so as to secure the user in the vestibule from parties outside the vestibule. During the predetermined period, the user then gains access to the building through a key actuated lock on the inner door of the vestibule. A piston and cylinder retarding element provides for the timed retraction of the dead bolt.

Abstract: A security system for allowing selective access to a secured area generally comprises first and second three wing center shaft ganged revolving door structures, each partially surrounded by upright facing curved side walls disposed in spaced apart relationship to define a mid-zone. A digital combination lock at the first entryway provides initial access. Any two wings of the revolving doors have an angular span less than that traversed by each side panel to define a lockable detection chamber. A gas ionization explosives detector is coupled to the detection chamber. The mid-zone comprises metal and X-ray detectors and a hand geometry reader. The second revolving door has an entryway actuatable by a pass card reader. The second revolving door provides access to the secure region.In operation, an individual seeking access punches a combination lock releasing the first revolving door allowing the wings to rotate and then lock, enclosing a detection chamber in which the individual is confined.

Abstract: A system of detaining a robber on the premises robbed after the robbery has taken place. The premises is provided with lobby entrances having inner and outer doors through which persons entering and leaving the premises must pass. Once a robbery commences, the doors to the lobbies are automatically locked. In the money handed to the robber, there is concealed a radio transmitter which transmits a narrow wave length signal. Mounted in the wall adjacent to each lobby inner door inside the premises proper there is mounted a receiver which is tuned to the narrow wave length and which has a limited range of reception on the order of about five feet or so. When the transmitter carried by the robber is within the receiving range of the receiver, the inner lobby door can be opened from inside the premises. Once the robber enters the lobby, neither of the lobby doors can be opened by the robber and he will be caught in the lobby.

Abstract: Credit card operated, automated teller machines are located in the vestibule of a bank where they may be accessed during normal banking hours. During off hours, a partition system segregates the vestibule from the remainder of the bank. Off-hour access to the vestibule is advantageously controlled by a customer activated door lock operated by the credit card and reader located at the bank door. Thus, access to the vestibule and the automated teller machines are controlled by the customer's own credit card.
