Abstract: A door handle with a door-side output shaft and a handle facing away from the door, the output shaft and handle having a common rotational axis and being connected via an electromechanical clutch, may be particularly compact and may have a particularly low energy intake for shifting the clutch by providing the output shaft with a recess on the side facing towards the handle, in which a coupling element is displaceably mounted; by providing the door handle with a receiving area for the coupling element 40 opposite to the recess; and by arranging a linear drive in the handle, the linear drive acting on the coupling element in order to move the coupling element in the axial direction so far out of the recess that the coupling element engages both into the recess as well as into the receiving area in order to close the clutch, and the coupling element is moved out of the receiving area back into the recess in order to open the clutch.

Abstract: A locking security system for motor vehicle wheel rims comprises a security housing, a locking assembly, and a plurality of grooved lug nuts. The security housing comprises a structure which covers wheel stud portions of an existing wheel rim. The locking assembly comprises a key lock mechanism located on an interior portion of the housing further comprising a plurality of locking plates which engage respective grooved lug nuts.

Abstract: A padlock includes a shackle having a channel disposed along an axis of the shackle. The padlock also has a plurality of dials each having a single detent. The shackle can also include a plurality of circumferential grooves formed in a spaced arrangement along the shackle, each groove corresponding to one of the dials.

Abstract: A car handler lock mainly includes a vertical frame having a U shape cut, and a lock device is arranged to the opening of the U shape cut. The car handler lock also includes a buckle body. The buckle body includes a sheet shield unit and a bridge buckle arranged between the shield unit and the lock unit of the vertical frame. The bridge buckle will cover the linking gaps between the shield unit and the vertical frame while the bridge buckle is locked to the lock device. The U shape cut of the vertical frame will be slid in and fixed to a shaft of the car handler, and the bridge buckle of the buckle body will be locked to the lock device so that the shield unit will provide an all-round protection to the car handler. The lock assembly is light and convenient by its sheet components.

Abstract: A key blank or key has a rectangular parallel metal shaped blade which has side edges formed with grooves for cooperating with a complementary shaped keyway; the sides of the blank having a portion grooved for registration, another portion grooved for top-level hierarchical master keying, and two other portions, one on each side of the blade, for further master key variations and different combinations. One of the two further sections being curvilinear and the other rectangular or angular cuts.

Abstract: A cylinder lock-key combination including a cylinder housing, a key and a plug which has a circular-cylindrical barrel surface and which is rotatable in an opening in the housing. The barrel surface of the housing includes a key recess whose width exceeds its depth, and a plurality of code pin channels are preferably disposed in several rows. Code pin tumblers present in the code pin channels co-act with one or more blocking elements, such as pins or side bars, disposed in channels intended to this end. The blocking elements block rotation of the plug when one side surface of an inserted key presents wrong code surfaces. There is provided in this way a compact lock construction, which also enables the use of many code pins.

Abstract: A lock that is tamper resistant and includes a lock member. Two tubes are disposed on the lock member. Each of the two tubes extend generally outwardly therefrom and each define a bore therethrough. The lock includes a closure member which has two shafts. The two shafts are inserted through the two tubes and detachable within the lock member when the lock is an installed configuration. A locking mechanism detachably locks the closure member to the lock member when the lock is in the installed configuration wherein the two tubes substantially cover the two shafts.

Abstract: A tow-deterrent lock for camping trailers includes a latch assembly and a latch bolt dock coupling with each other. The latch bolt dock has a transverse beam on one end that has an inner side bonding to a spherical shell which has a housing chamber with an opening. When a coupling dock extending from a camping trailer is coupled with a towing rod of a vehicle, the housing chamber of the spherical shell may house a fastening nut located below the towing rod to couple with the latch bolt dock and latch assembly to confine and lock the coupling dock and the lower end of the spherical head rod to form a theft-proof protection. When the camping trailer is not coupled with the vehicle, the spherical shell may be wedged into a spherical trough of the coupling dock to couple with the latch bolt dock and latch assembly to lock the coupling dock and form a theft-proof protection. Thus the invention can provide locking and theft-proof function in two use conditions.

Abstract: A trailer hitch module for engaging a trailer tongue socket includes a base and a ball fixed to the base for engaging a socket cup. A locking arm is provided and pivotally attached to the base so that it is movable in a plane parallel to the base between a close position engaging a protruding lip of the socket in order to prevent removal of the socket from the ball and an open position away from the lip in order to enable removal of socket from the ball. A lock mechanism is provided for securing the locking arm in the closed position.

Abstract: A door lock device is disposed on a door (1). The door (1) has an upper through hole (11) and a lower through hole (12). The door lock device has a latch bolt device (6) disposed on the door (1), a case frame (2) having an upper hollow cylinder (22) inserted through the upper through hole (11) and a lower hollow cylinder (23) inserted through the lower through hole (12), a first pressing plate (8) disposed on the case frame (2), a core (3) disposed in the upper hollow cylinder (22), a lock fastener device (4) disposed in the upper hollow cylinder (22), and a drive mechanism (5) disposed in the upper hollow cylinder (22). The drive mechanism (5) has a rack (53) to drive the latch bolt device (6). A locking plate (71) covers the upper through hole (11) and the lower through hole (12). A decoration plate (72) is disposed on the locking plate (71). A second pressing plate (8′) is disposed on the decoration plate (72).

Abstract: An improved combination lock includes a plurality of patches of different daylight fluorescent colors with or without additional nonnumerical indicia, for indicating a predetermined combination. Alternatively, the patches can all be of the same fluorescent color and used as a contrasting background for the additional nonnumerical indicia. The additional nonnumerical indicia can comprise different geometrical patterns including sets of at least three parallel lines, or pictures of different animals. The indicia are preferably made larger than is conventional.

Abstract: An antitheft device for attachment to a steering wheel of an automobile comprising an elongated body member having two parallel passageways extending in a longitudinal direction. A first hook is secured to the body member for engagement with a portion of the steering wheel. The first hook engages the wheel from the inside of the rim, with the body member extending outward beyond the periphery of the steering wheel, an elongated rod member, adapted to move in telescopic fashion in one of two passageways formed in the body member, and extending longitudinally therein. A second hook, secured to the rod member, engages the inside portion of the steering wheel at a point diametrically opposed to that of the first hook. A second elongated rod member is adapted to extend in telescopic fashion in a direction opposite to that of the other rod member.
