Abstract: A numerical combination lock 1 has a turning knob 3, by means of which a cam plate 4 can be turned in order to operate a drop lever 5 that is hinged to a locking bolt 2 of the lock 1 and in this way to draw the locking bolt back to the open position. This can be done only by means of the correct selection of an opening combination which, also with the aid of the turning knob 3, has to be set through repeated turning. Following each setting, the turning knob 3 can be displaced in an axial direction in order to operate a switch 11 on a printed circuit board 35 each time in accordance with that particular setting value. In this way, an electric motor 12 is controlled that moves a coupling member 14 on a sliding bar 13 into the area of a first working surface 15 of the cam plate 4, if the correct opening combination has been entered.

Abstract: A combination lock adapted for securing skis, bicycles and the like, having a lock housing in which setting disks for setting a lock combination are rotatably supported and from which housing there extends fixed thereto, one end of a loop, the other, free end of which is insertable into an insertion channel in the lock housing and is engageable by the inners of the lock. In this respect within the insertion channel of the lock housing a latch is provided for catching the free end of the loop. The latch is seated, displaceable against spring biasing, on a setting-disk mounting shaft and, when the lock combination is correctly set, is disengageable, by a collar on the setting-disk mounting shaft which continues into an outwardly extending actuating button, by displacement together with the mounting shaft.

Abstract: The combination can be set by discs which are toothed on one of their faces. This toothing causes movement of internal bushes or rings which are at least partly contained in seats in a manually controllable slider, which can be moved against a spring when, having set the exact combination, a radial passage in said bushes or rings becomes disposed in a position such as to allow radial movement of the bushes and thus movement of the slider and opening of the lock. The combination can be changed by setting the existing combination and moving the slider and thus the rings, so that these latter disengage from the toothed discs which can thus be rotated into another position without dragging the bushes with them.

Abstract: An improved lock assembly having a plurality of peripherally gated tumbler wheels supported within a housing for rotation about a common axis. A peripherally gated control cam is mounted to the tumbler wheel axis to provide cam operated movement of a fence lever and rotatably attached lock bolt between extended and retracted positions when the peripheral tumbler wheel gates are aligned. A single spring is provided for serving the dual purpose of biasing the fence lever towards the control cam and securing the fence lever to the bolt. Further, precise positioning of the lock bolt and lever when the lock bolt is moved to its extended position are provided by a three point positioning configuration in which special surfaces on the lever are moved into abutment with the lock housing. A new relock spring configuration and system is provided for preventing retraction of the lock bolt when the housing backplate is removed.

Abstract: A tumbler wheel type lock mechanism for use in key locks, dial operated combination locks and the like, including plural tumbler wheels in a lock casing having gated rim portions encircling hub portions which may be adjusted to different angular positions relative to their associated rim portions. A pivoted fence lever is normally releasably latched in a raised inactive position, and a releasing spring is activated by a control cam to impact against a shoulder formation on the fence lever for releasing the latter from such latched condition and impelling it to coupled relation with the control cam when the tumbler wheels occupy a predetermined alignment whereby the lock cam can be unlocked by operation of the control cam.

Abstract: Padlock constructed to resist efforts aimed at unauthorized opening of the padlock. The padlock casing has a rocker between the legs of the shackle of the padlock, and pivoted on a fixed pivot extending transversely of the padlock casing and held in a locking position by tumbler disks. A latch bolt is slidably carried by the rocker and biased by a spring to engage a latch bolt receiving notch in a shorter leg of the shackle. The rocker has an arcuate face struck from its pivot and facing oppositely from the latch bolt receiving notch of the shackle. The arcuate face slidably engages and cooperates with the arcuate face of a back-up fin or segment extending inwardly from the inner wall of the lock casing, backing up and forming a guide for said rocker. A camming and stop segment on the rocker slidably engages one side of the fin and comes into engagement with the lock casing to limit inward movement of the shackle, and to cam the rocker into a return direction.
