Consequently, the code-locked keystroke bodies are fixed and cannot be pressed in the lock status.

Abstract: A combination-changeable complex lock includes a movable plate, a combination lock, and a sliding member. The combination lock is composed of two notched rotating discs, two gearwheels, and a combination-alteration control device. The combination-alteration control device is rotatable to separate the gearwheels from the notched rotating discs for allowing change of the set combination. The sliding member is controllable by the combination lock to engage or disengage the peripheral notches of notched rotating discs. When the combination lock is locked, the sliding member is disengaged from the notched rotating discs and forced against the movable plate to bias the movable plate.

Abstract: A combination resetting member for a cable lock mainly contains a stationary piece and a movable piece. The movable piece is concentrically positioned inside the stationary piece and two diametrically opposing pins penetrates through the stationary piece, two grooves of the movable piece, and into two corresponding holes on the tip of a column of a female lock member. The movable piece has two diametrically opposing flanges on the front surface and two diametrically opposing blocks on the back surface. The flanges and the blocks are orthogonal to each other. Corresponding to each of the blocks but on the front surface, there are a shallower U-shaped groove and a deeper U-shaped groove. The movable piece can be forced to move orthogonally to the pins and the pins therefore could shift from the shallower grooves to the deeper grooves and vice versa.

Each of a left and a right push buttons has a latch hook for locking with the tab. A bounding resilient plate is disposed in the slot for bouding the tab out of the slot. The numeral wheels serve to drive the notched wheel to rotate. The notched wheel serves to drive a sliding plate to shift within the lock casing. A numeral-changing button in a numeral-changing hole of the lock casing can be pressed by a sharp article, whereby a projection at one end of the numeral-changing button is engage with a protuberance of the sliding plate to lock the sliding plate for turning the numeral wheels to change the numerals.

Abstract: A locating device for a numeral wheel of a numeral lock, comprising a lock body, several numeral wheels, notched wheels and springs, wherein a locating channel is formed on a surface of the notched wheel in front of projections thereof and a latch spring is disposed in the locating channel. The latch spring has upward projecting portions, whereby when the notched wheel is fitted into the numeral wheel, the projecting portions of the latch spring and the projections of the notched wheel are all engaged with recesses of the numeral wheel. When it is desired to adjust or change a lock code, a pushing pin is used to push the notched wheel backward so as to disengage the projections from the recesses while keeping the projecting portions of the latch spring resiliently engaged with the recesses. Therefore, the numeral wheel can be rotarily adjusted and located without totally disengaging from the notched wheel so as to avoid poor location and jumping of the numeral wheel.

Abstract: A luggage latch has a housing mounted on a piece of luggage and a latch body or slide displaceable in the housing between a latched and unlatched position and engageable only in the latched position with a latch component on the luggage lid to retain the latch component.

Abstract: A barrel and cable type combination lock having clutches with changeable combination wheels mounted thereon. A grooved cable shackle is held in a lock position by balls engageable with the shackle grooves and the clutches and wheels. A barrel removable end cap functions to hold the combination wheels in place when the lock is operable, and upon the removal of the cap the combination wheels can be moved to create a new combination. Cap detent means cooperate with the cable shackle to hold the cap in position when the lock is in lock position and permits the cap's removal when the lock is unlocked.

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 lock includes several encoding buttons, a latch plate is slidably movable between two terminal positions and has a plurality of locking pins; a plurality of lock disks each have on one side a radial groove for respectively engaging the locking pins or being disengaged therefrom, each disk further having on its outer side a diametrical groove in which respective slide locks are permitted to slide, an encoding release slide moves said slide locks; a plurality of gears are respectively connected to the encoding buttons and positioned for engagement with the slide locks, the gears are prevented from turning, thereby preventing the encoding buttons from being turned when the respective slide lock engages the gear and the locking pins are situated in the respective radial grooves, the gears are coupled to the lock disks when the locking pins are out of the respective radial grooves, the release slide when moving the slide locks decouples the lock disks from the gears and the encoding button; and res

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: A novel combination lock, mainly comprising a bolt, a case, an actuating button, three steel balls, and a slotted rod, characterized in that the combination numbers can be randomly changed for security.
