Abstract: To provide a push button lock which includes a housing on which a plurality of depressible push buttons are located, a lock pin which moves axially with the push button and being engageable with and disengageable from the push button, a lock plate formed with a plate key hole and plate lock hole, a reset plate which is provided parallel to the lock plate, a driving cam linked to a deadbolt lock, and the security-code controller detachably attached to the housing. A mechanism and components for setting and storing a security code for locking and unlocking are assembled in a cartridge. The cartridge is detachably attached to the inside of the housing so that various surface designs are available.
Abstract: A locking arrangement includes a latch assembly, a locking mechanism, and a user operable opening member. The locking mechanism holds the latch assembly in a latching position when the locking mechanism is in a locked condition and allows the latch assembly to move to an unlatching position when the locking mechanism is in an unlocked condition. The opening member is movable from a normal position to an opening position. When the locking mechanism is in the unlocked condition, movement of the opening member to the opening position moves the latch assembly from the latching position to the unlatching position. The opening member is operatively connected to the latch assembly by a compressible member, such that when the locking mechanism is in the locked condition, movement of the opening member to the opening position compresses the compressible member without moving the latch assembly out of the latching position.
Abstract: There is provided a button-operated lock device capable of increasing a setting amount of information in response to operation of a control button, obtaining a large setting amount and a wide-range of selection thereof, enhancing safety performance, simplifying the structure and achieving a small size and a light-weight, thereby achieving a low manufacturing cost, executing such various operations as setting or inputting information and altering thereof correctly, safely, easily and rationally, and preventing decoding or perceiving of preset or inputted information so that any third party is prevented from making a falsification and/or conversion of this device.
Abstract: A push button combination lock type gas cap and an actuator forming a part thereof, takes the form of a casing which may be mounted to an open end of a fuel tank filling neck with a stopper mounted within the casing for movement between a first position in which the cap is removable from the filler neck, and a second position where the cap is locked thereto. A first center push button mounted on the casing for movement in the direction of its axis between projected and depressed position, shifts the stopper to the first position for locking the cap to the filler tube upon depression thereof. The first push button is maintained in depressed position with a laterally shiftable slide plate operatively engaging the first push button for normally preventing retraction of the first push button absent a selective depression of one or more of a plurality of second push buttons mounted circumferentially about the center push button.

Abstract: There is described a case for valuable documents, such as notably checks, credit cards, bank notes, etc., comprised of a box with a lid and a closure which may only be opened by inputting a code number, as well as a capsule or phial filled with a pressurized liquid which can destroy or make useless said documents, in which said capsule or phial is made completely or partly from fusible material, and said capsule or phial may be opened or unplugged electrically when electric or electronic means the case is fitted with, are operated due to any break-in attempt.
Abstract: This electronic combination lock is operated by depressing the proper combination of pushbuttons mounted on the faceplate of a circular handle, then rotating the handle to open the bolt. The pushbuttons are held outwardly by radially extending spring wires within the handle that also provide electrical connection, when a pushbutton is depressed, to inclined contacts mounted to the rear of the faceplate. Electrical leads extend through a hollow shaft connected to the handle.The bolt is restrained in the locked position by a magnetically actuated locking pin which projects into a bore in the bolt. The shaft is connected to the bolt by a spring. When the proper pushbuttons are selected, electrical circuitry disclosed herein actuates the magnet, removing the pin and permitting the bolt to be opened by handle rotation. If the wrong combination is depressed, an alarm signal is produced, the magnet is not actuated, and rotation of the handle expands the spring without moving the bolt.
Abstract: This invention relates to electrical combination locks that compare a sequence of input signals with a stored sequence to permit the lock to be opened. The mechanical features of the lock are characterized by an arm and control member within the lock structure that inhibit bolt motion in the absence of the proper combination. The electrical circuit enables the combination to be changed readily and uses very little power.
