Axially Movable Bolt Patents (Class 70/217)
  • Patent number: 9556646
    Abstract: The present invention is directed to a latch actuating device that includes a handle and a base. The handle has a cavity that houses a lockset, a drive cam, and a driven cam. The drive cam has a protrusion that is removably received within a locking receptacle in the base so as to permit and restrict rotation of the handle with respect to the base. The drive cam causes the driven cam to translate along a rotational axis of the drive cam when the drive cam is rotated by the lockset, thus effectuating the insertion and retraction of the protrusion with respect to the locking receptacle.

  • Patent number: 7155947
    Abstract: A control knob having a locking mechanism that can be pressure-activated and controlled from the outside by the operator. When activated, the locking mechanism engages a structure on which the knob is mounted, preventing the rotation of the knob. The locking mechanism includes a keylock having a latch that can be turned with a key so as to engage a catch of the knob-housing seat of the locking mechanism.

  • Patent number: 6923029
    Abstract: An operating device for doors, windows, etc. comprises a rosette (20) for holding a rotating handle (10) whose head (12) contains a lock cylinder (18) with an axially displaceable locking bolt (44) that is axially spring-loaded and automatically assumes an engaging position at a defined angle of rotation of the handle (10) by sliding over a stepped locking sleeve (30) of the rosette (20). The lock cylinder (18) has a core (40) with a radial opening (50) in a non-rotating wall (58) for controlled movement of a spindle (48) that radially extends from the locking bolt (44) which engages the locking sleeve in defined angular positions of the handle (10). The opening (50) extends over a peripheral angle of e.g. 180° to 220°, and is a contoured window having a lower flat segment (52), a depression (54) and a steeper segment (flank 56).

  • Patent number: 6860129
    Abstract: A lock mechanism operated by inner and outer lever handles provides a security classroom function and includes inner and outer lock mechanisms that are independently switchable between locked and unlocked states by inner and outer lock cylinders and keys. The inner handle always operates the lock mechanism to retract a latch bolt. The outer handle can only retract the latch bolt when both the inner and outer lock mechanisms are in the unlocked state. The outer key can retract the latch bolt when the inner lock mechanism is in the locked state, but cannot change the inner lock mechanism to the unlocked state or enable the outer handle, thereby ensuring positive control over the locked state of the outer handle from the inner side.

  • Patent number: 6807833
    Abstract: An unlocking device for the lever handle door lock includes an inner lever, an outer lever, an inner mounting plate, an outer mounting plate, a spindle, an inner actuating rod and an outer actuating rod. The inner mounting plate and the outer mounting plate mount the inner lever and the outer lever. Each of the inner lever and the outer lever has an assembling hole so that the inner lever and the outer lever are correspondingly connected to the inner actuating rod and the outer actuating rod for separately operating a latch bolt unit. The inner actuating rod has an end capable of disengaging from that of the outer actuating rod so as to avoid driving the inner actuating rod.

  • Patent number: 6735993
    Abstract: A lock mechanism for use with lever handles includes a lock core and a latch mechanism that is rigidly connected to the lock core to prevent the lock core from rotating in the door. Through-bolts are not needed, allowing a small diameter rose to be used. Stops and a spring return mechanism are entirely located within the lock core, allowing the rose to be thin. The lock core defines the rest position for the lever handles at an angle slightly above horizontal. To avoid the necessity for producing different locks in left and right-hand configurations, the lock core is made substantially symmetrical about a vertical plane, instead of a horizontal plane, and the inner and outer sides of the lock mechanism can be interchanged. A heavy-duty locking piece, including a pair of locking lugs that directly engage the lock core near its inner perimeter, allow the lock to withstand abusive forces applied through the lever handle.

  • Patent number: 6526330
    Abstract: A vacuum processing apparatus is composed of a cassette block and a vacuum processing block. The cassette block has a cassette table for mounting a plurality of cassettes containing a sample and an atmospheric transfer means. The vacuum processing block has a plurality of processing chambers for performing vacuum processing to the sample and a vacuum transfer means for transferring the sample. Both of the plan views of the cassette block and the vacuum processing block are nearly rectangular, and the width of the cassette block is designed larger than the width of the vacuum processing block, and the plan view of the vacuum processing apparatus is formed in an L-shape or a T-shape.

  • Patent number: 6412318
    Abstract: An electric cylindrical lock comprises a chassis, an inner spindle, an inner handle, a latch assembly, an outer handle, and an outer spindle. A tubular seat is mounted around an end of the outer spindle and includes a positioning groove aligned with a slot of the outer spindle. When a solenoid mounted in the tubular seat is energized, a protrusion of a locking plate in the tubular seat is engaged in the positioning groove of the tubular seat to thereby prevent rotation of the outer handle. When the solenoid is inoperable, the lock cylinder is turnable by a key to cause longitudinal movement of the locking plate, thereby disengaging the protrusion of the locking plate from the positioning groove of the tubular seat.
