Abstract: A padlock includes a housing, a shackle, a limit knob, a movable block and a lock core. The housing has an opening in a wall thereof. The shackle has a shaft portion movably mounted in the housing, and a locking portion extended from the shaft portion and located outside of the housing. The limit knob is partly received in the housing via the opening and has a button located outside of the housing. The movable block is disposed on the limit knob and capable of moving to a predetermined position which is outside of the housing. The lock core has a rotor configured to be driven by a key so as to move the limit knob to a first position where the button of the limit knob keeps the shackle from rotating and a second position where the button of the limit knob allows the shackle to rotate.

Abstract: A combined bicycle pedal and lock and a method for its use, which is an integral part of a bicycle and serves both as an ordinary bicycle pedal and as a means of locking the bicycle to an object which is not a part of the bicycle. The combined bicycle pedal and lock includes a pedal shaft, several main components, which carry the majority of the load applied to the pedal when riding the bicycle, a complementary locking assembly, which has two modes, a folded mode when the combined bicycle pedal and lock is serving as a pedal, and mode that can be extended when the combined bicycle pedal and lock is serving to lock the bicycle to a suitable object, as well as a short pedal shaft, and a locking mechanism which is operated by means of a key, combination wheel, or any other suitable means.

Abstract: This invention relates to a lock assembly to be used in conjunction with two or more padlock assemblies. The lock assembly comprises a main body 1, a main shackle 2, and a locking portion 7. When all subsidiary padlocks 5, 6 are locked into the apertures 3, 4 the main shackle 2 cannot be opened. The removal of either subsidiary shackle allows the locking portion 7 to circumvent the second subsidiary shackle and the main shackle 2 may be opened. This allows two persons to independently use the padlock without sharing keys or other secure information. Moreover the lock assembly may be used with any secure fitting designed for use with a traditional padlock.

Abstract: A secure funds device for use with a computer system, such as a personal computer, for transferring funds, in response to a funds transfer request for amounts of funds from the computer system, to a funds receiver. One or more electronic cash devices store electronic funds and transfer funds in response to funds transfer request when authorized by an authorization signal. A processor is used for connecting the funds transfer request from the computer system to the electronic cash device and for transferring electronic funds from the electronic cash device to the computer system when the authorization signal is present. User control means, including for example a pushbutton switch and an LCD display, that is not accessible by the computer system is used for providing the authorization signal. The secure funds device has a secure interface that prevents the computer system from generating the authorization signal.

Abstract: A padlock concept consisting of a novel shackle comprised of two tapered shackle elements arranged so that they overlay each other to enclose and opening sufficient to accept the staple of a hasp or attachment device. The shackle elements are connected at one end and when unlocked and unlatched are free to move apart, in a motion causing the two shackle elements to separate, providing a clearance between them, at the unconnected end. Each shackle element includes an opening to allow the staple of the hasp to pass to the common opening. This clearance occurs in opposing elements so that when the elements are brought together or closed the staple of the hasp is completely enclosed by the two shackle elements which substantially fill the space available within the hasp staple. The elements are then latched and locked to provide the security function of a padlock engaged with the staple of a hasp or attachment device.

Abstract: A simple bicycle lock structure which comprises an outer cylinder and a shackle; one end of the outer cylinder is mounted with a locking assembly, while the other end thereof is mounted with an outer-cylinder-positioning assembly, in which a movable sleeve has a through hole, being perpendicular to a pin hole; the through hole is in communication with a round hole on the outer cylinder. The shackle has a rotary section which is perpendicular to the shackle body; the rotary section includes a circular groove and a symmetrical groove; after the rotary section is inserted in the movable sleeve, a fixing pin will be engaged with the rotary section in a pivotal manner. Other end of the shackle has a locking section with a locking groove and a bevel facet. As soon as the locking section is inserted into a round hole on the outer cylinder, the locking section will be engaged with the locking assembly to become locked up.

Abstract: An improved padlock, and in particular, one having a lock body which has a pivot at one end and a lock mechanism at its other end, a shackle having two legs of equal length where one leg is connected to an elliptical connecting end and the other leg is connected to a notch.

Abstract: An improved security lock for automobiles and the like and of the type designed to lock a control pedal and the steering wheel together is disclosed. The security lock includes a telescopic part featuring an improved length adjustment for speed and strength and the use of a friction device; protective outer member mounted for free rotation about one end of the telescopic part housing the lock cylinder to guard against forceful breaking of the telescopic part and against gaining access to the lock cylinder; and an improved shackle to fit about the steering wheel and being pivotally anchored in the telescopic part.

Abstract: A lock of the type preferably used with sliding doors having first and second elements constituted by solid cast material, the first element having a head disposed at one end thereof with a recess and a cavity therein. The second element is rotatably mounted at one end thereof to the first element such that the other end of the second element may be rotated into and out of the recess in the head of the first element. The second element also has a cavity therein which aligns with the cavity of the first element when the lock is closed. The cavity in the second element has a channel located in a wall of the cavity. A locking element is movably disposed in the cavity of the first element and is movable into and out of engagement with the cavity of the second element. The locking element has a locking device disposed offset from the geometric center, and preferably eccentrically, of the locking element.

Abstract: The present invention relates to a padlock designed for application in the locking of sliding doors with two panels that meet by their butt ends or vertical edges, which are held fast to one another by the padlock itself, being constituted by two flat bodies formed by a variable number of platens super-imposed and joined with respect to one another by means of rivets in such a way that the said bodies have an exterior quadrilateral zone, which is extended in convergent form to terminate in a semicircular shape at its opposite end, thus originating a number of flat and lengthened bodies that are arranged according to parallel and spaced planes; provision having been made for the connection of the said bodies to be effected through the semicircular end zone of the said bodies, by virtue of a shaft common to both, which shaft is fixed and without movement, causing one of the bodies to be fixed while the other is mobile and rotates around the said shaft, the said mobile body having a cylindrical housing in its qu

Abstract: A light-weight type lock having a body assembly and a pair of detachable hasps which protrude from opposite ends of the body. The body is box-like in form with movably related cover and configured body, securable together by keylock operation. The hasp ends are captured between the inner body configuration and the outer body when locked in assembly. In particular embodiments the hasps may be flexible members such as chains, or may be rigid "U" shaped members, either entirely releasible from the body assembly or releasible at one end of the hasp, and the outer and inner body members may slide or may pivot relative to each other to secure and to release the hasps, providing either alternative or simultaneous hasp release.
