Moreover, each securing pin has at least one additional recess, the cross-sectional profile of which corresponds to the cross-sectional profile of the longitudinal rib, and the depth is smaller than the height of the longitudinal rib.
Abstract: A key holder arrangement for one or a plurality of spare keys, with which advertising may be effectively used, comprising a planar base member approximately the size of a typical business card, and of a thickness approximating the thickness of a key. The base member has opposing faces thereon, and one or more cutouts therein, each cutout being of a size closely conforming to the key to be received, such that the key can be frictionally retained therein. One of the faces of the base member is coated with a pressure sensitive adhesive, with a backer sheet normally residing on the pressure sensitive adhesive, to prevent the base member from adhering to an extraneous object. The backer sheet is to be readily peeled away from the adhesive preparatory to the placement of the backside of a business card in contact with the adhesive, and in careful alignment with the base member.

A pick-resisting improvement to the cylinder lock assembly includes facial piece defined with a plurality of knobs protruding partly into the key entry passage of the lock assembly.
Abstract: A side lock (20) for a roll-up door (21) mounted on a body includes a keeper (27) mounted on a jamb (23) adjacent an access opening (22). A hook member (28) is pivotally mounted on a panel (25) and is arranged to selectively engage a catch (59) mounted on the keeper. The hook member has an upper cam surface (76) and a concave surface (78). The hook member also has a lower cam surface (75) which is adapted to selectively engage the catch when the door is lowered to selectively displace the hook member against the opposing bias of a spring (91) to permit the tip (66) of the hook member to pass beneath the catch. The improved side lock is self-tightening.
Abstract: An adjustable lock for a cassette tape player for preventing the theft and unauthorized use of the cassette tape player is disclosed. The adjustable lock comprises a housing mounted outside of a tape receiving chamber. The housing has a hook extending rearwardly and laterally outwardly therefrom so as to be insertable into one end of the tape slot in the cassette tape player and a bolt extending rearwardly and laterally outwardly from the housing whereby the engaging end of the bolt is insertable into the end of a tape slot opposite the hook. The adjustable lock also includes a tubular key lock assembly which mounted on the face of the housing is operationally associated with the bolt. In particular, the tubular key lock assembly is adapted to extend or retract the bolt by a distance rearwardly from the housing which is adjustable.

The tubular casing has an central through hole for rotatably receiving a locking spindle. The locking spindle includes a driver pin sleeve having a set of bore holes, each for receiving a driver pin. A rotating shaft protrudes from a first side of the driver pin sleeve, and a protrusion with a keyway slot protrudes from a second side of the driver pin sleeve. A tumbler sleeve is provided on the rotating shaft and is fixed to the tubular casing. The tumbler sleeve has a distributed annular set of blind holes, each for receiving a tumbler spring and a tumbler pin, which are alignable with the bore holes in the driver pin sleeve. A shielding ring having an eccentric flange is received in a key-end of the tubular casing to shield some of the driver pins.
Abstract: A double ended key ring includes a housing and a cover which are pivotally connected. A bias mechanism urges the housing and cover into an open position thereby providing access to an opening therebetween for mounting or removing keys or keyholders. A latch mechanism is pivotally mounted relative to the housing for releasably holding the cover in the closed position. The entire bias mechanism and the latch mechanism is effectively concealed when the key ring is in the engaged or closed position, in which position the removal of keyholders is precluded.
Abstract: A self-locking electronic lock system is illustrated in association with safe doors having a door locking bolt works manipulated between door open and door locked positions by a door mounted handle. The bolt works includes a link which moves the door bolts and in turn is locked by an electronic lock in accordance with the present disclosure. The electronic lock has a spring bias bolt normally biased into a locking gate provided on the link and is operated to a withdrawn position by an associated digital input electronic signal generating means.

Abstract: A permutation lock, particularly for storage compartments, has a variable combination such that an opening combination corresponds to a combination to which the lock was set by advancement of the bolt into the locked position. The lock has an emergency opening mechanism which can be activated and deactivated by key actuation. To increase the security value with simple actuation of the permutation lock, the emergency opening mechanism can be deactivated only by means of a reactivation key which can be inserted into a lock cylinder.
Abstract: This invention is a bicycle lock, comprising a two-way horizontal swivel bicycle frame clamp which is secured by a nut and bolt to the bicycle frame. The clamp wraps around the bicycle frame just below the seat post and is secured in place by said nut and bolt. The lock also includes a 90.degree. pivot rod, one end of which is connected to said clamp and acts as a hinge, allowing the unit to move back and forth in a horizontal direction. Also included is a two-way cylinder which is attached to said pivot rod, permitting the unit to move back and forth in a vertical direction similar to the movement of a hinge. There are also flat metal tracks such that one end of one track is attached to said cylinder and the other end is connected to the other tracks, one after another in line, and held together by means of rivets. The rivets slide along the inside of the tracks, acting as a swivel and also allowing the tracks to extend or retract.
Abstract: A lock for a sliding door includes front and rear housing members that clamp front and rear faces of a door panel adjacent an opening that is formed through the door panel. Aligned cavities in the front and rear housing members cooperate with the opening to provide a compartment that mounts a latch bolt member for forward and rearward movement. The latch bolt member has a rearwardly extending formation that projects through a hole formed in the rear housing member for selectively engaging structure located behind the door to releasably latch the door in its closed position. An operating mechanism connects with the latch bolt member and includes components that extend forwardly and rearwardly through aligned openings formed through the front and rear housing members to enable the latch bolt member to be moved forwardly and rearwardly between unlatched and latched positions, and to releasably retain the latch bolt member its unlatched and latched positions.
Abstract: A timer controlled lock operating device for a refrigerator or the like is provided and consists of a plate affixed to the side wall of the refrigerator, a link chain having one end secured to the plate, a housing affixed to the front door of the refrigerator, a shackle extending from within the housing and engaging an opposite end of the link chain, and a mechanism within the housing for opening the shackle at a predetermined period of time so that a person can remove the link chain from the shackle and open the front door of the refrigerator to gain access therein to obtain food.

Abstract: An improved bicycle lock, featuring a U-shaped shackle, a cross bar and means for securing one to the other, is disclosed. The means for securing the shackle to the cross bar also functions as a fulcrum, permitting a tilting movement between the two parts, required in assembling and dissassembling them. The means further includes a locking mechanism removably mounted in the cross bar in between the shackle's legs, and features a dead bolt. The cross bar extends beyond the shackle's legs less than twice the diameter of one of those legs, resulting in a compact and sturdy design. A plastic cover encloses at least the cross bar and is preferably formed of two parts slidably fitted over the cross bar, with means for securing the two parts to one another. Preferably, an environmental protection means is provided for the locking mechanism.
Abstract: A fastener includes a threaded pin and an internally threaded collar. The threads can freely be run without impediment during tightening. After the fastener is tightened, a tool engages a shoulder on the collar and presses a deflector against the collar on the pin to deflect it so as to form a lock against loosening.
