Definitions
- the present invention is related to a lock, and especially to a structure of lock wherein a plurality of receiving holes and alignment holes are provided in and by the central keyhole of a lock core to receive therein a plurality of juxtaposing and integrally connected pushing pins and alignment pins.
- a key enters the keyhole to displace the pushing pins and alignment pins, an engaging hole in each alignment pin is aligned respectively with a longitudinal slit on the lock core to allow insertion of an engaging strip in the longitudinal slit into the aligned engaging holes, hence the lock core can be rotated in the cylinder for unlocking.
- Locks are widely used at the locations or spots wherein guard against, prevention from and limitation to access of things are required. Thereby, a limited area can avoid being intruded or destroyed. Locks are very important to the functions of protection and guard. Hence people have many chances to use locks in their life, and locks always keep their important position.
- the most necessary structures in locks are the structures of lock cores, cylinders, locking beards, locking pins or bolts.
- the most widely used locks nowadays have juxtaposing locking pins, wherein the locking pins are vertical ones.
- the cylinders With the design of such kind of locks, there must be larger spaces to receive locking pins, and the cylinders will have protruding square portions to receive the locking pins. These render the production quite troublesome, and make mounting of locks by locksmiths quite difficult. Abutment between locking pins may induce friction action and renders the locking pins worn, thereby, inconvenience in opening and locking the locks may be increased.
- the inventor of the present invention develops the novel lock structure of the present invention for locking, which structure is a design using juxtaposing locking pins cooperating with engaging function of an engaging strip.
- the present invention has a main object to have juxtaposing and integrally connected pushing pins and alignment pins received in the central keyhole of a lock core, and to insert an engaging strip into a plurality of aligned engaging holes of the alignment pins after the engaging holes in the alignment pins are moved to align with a longitudinal slit on the lock core, hence the lock core can be rotated in a cylinder for unlocking.
- the present invention has a secondary object to have the pushing pins and alignment pins limited by the receiving holes and alignment holes provided in the a lock core, thereby, the pushing pins and alignment pins are correctly positioned and not deviated.
- the third object of the present invention is to make the positions of the engaging holes on the alignment pins untidy, and the engaging holes can only get tidy after they are all moved to correct positions to allow the engaging strip to enter them, this can effectively prevent an external force from undue damaging.
- the fourth object of the present invention is to make the pushing pins and alignment pins be parallelly connected in juxtaposition relationship in the lock core; this can strengthen the structure of the pins.
- the fifth object of the present invention is to make the pushing pins and alignment pins be integrally combined mutually or connected with a connecting plate, thereby, a plane surface is formed between the pushing pins and alignment pins.
- the sixth object of the present invention is to make each alignment pin a straight board to be parallelly connected in juxtaposition relationship with a corresponding pushing pin.
- the seventh object of the present invention is to provide all the pins and the engaging strip within the lock core; thereby, the cylinder of the lock does not require further space to receive the pins.
- the eight object of the present invention is to make the engaging ends of the engaging strip in the form of a straight board engage directly in a groove provided on the cylinder; thereby, engaging effect is good.
- the ninth object of the present invention is to provide the pushing pins in the shape of rods provided transversely on the upper portion of the alignment pins, the rod shaped pushing pins extend into a guiding way of a key, the guiding way pushes and displaces the alignment pins to suitable positions to make the engaging holes on the alignment pins be aligned with the longitudinal slit on the lock core; thereby the engaging strip engages in the engaging holes to allow the lock core to rotate in the cylinder.
- the tenth object of the present invention is to provide the alignment pins each with a protruding portion on the lower portion thereof, an engaging rod and a coil spring are provided on the protruding portion to return the alignment pins to their original positions when they are displaced.
- the eleventh object of the present invention is to provide recesses on the bottoms of the protruding portions of the alignment pins to receive springs; the alignment pins can return to their original positions when they are displaced.
- the lock 10 of the present invention is comprised of a lock core 20, a plurality of pushing pins 25 and alignment pins 26, an engaging strip 27 and a cylinder 30.
- a plurality of receiving holes 22 and alignment holes 23 are provided in and by the central keyhole 21 of the lock core 20.
- the lock core 20 has on the surface thereof a longitudinal slit 24 of which the bottom is in communication with the alignment holes 23 (as shown in Fig. 3 and 4).
- the engaging strip 27 (as shown in Fig. 1 and 5): is elongate and received in the longitudinal slit 24 of the lock core 20; both ends of the engaging strip 27 are elastically supported at the bottoms thereof by a spring 271 to render the top 274 of the engaging strip 27 exposed to the outside of the lock core 20.
- the cylinder 30 is slipping over the lock core 20, the inner wall thereof is provided with an engaging groove 31 mating with the engaging strip 27 for embedding of the top 274 of the engaging strip 27.
- the alignment pins 26 are received in the alignment holes 23, the alignment pins 26 have on the shanks thereof engaging holes 261 located in different levels;
- the pushing pins 25 are integrally and parallelly connected with the alignment pins 26 (as shown in Fig. 1A and 34A) and are received in the receiving holes 22 of the lock core 20, and further are elastically supported by a plurality of second springs 252 respectively to render the alignment pins 26 and the engaging holes 261 thereof located in different levels (as shown in Fig. 3 and 4).
- a key 40 enters the central keyhole 21 of the lock core 20 (as shown in Fig. 1 and 6), it abuts the tops of the pushing pins 25 with its alignment serration 42 to move the alignment pins 26 and to align the engaging holes 261 (as shown in Fig. 7 and 8) with the longitudinal slit 24 of the lock core 20.
- the lock core 20 is rotated with the key 40 (as shown in Fig. 8 and 9)

- the lock core 20 can be rotated clockwise (as shown in Fig. 9) or counterclockwise (as shown in Fig. 10) in the cylinder 30.
- the lock core 20 can push the engaging strip 27 when in rotating, so that the arciform top 274 of the engaging strip 27 will be pressed to move along the curvature of the engaging groove 31 toward the interior of the lock core 20.
- the bottom portions 275 of the engaging strip 27 can be moved gradually into the aligned engaging holes 261 of the alignment pins 26 to be completely released from engagement of the engaging groove 31 of the cylinder 30.
- the longitudinal slit 24 of the lock core 20 is rotated back to align with the engaging groove 31 of the cylinder 30, then the engaging strip 27 in the longitudinal slit 24 is pushed by the spring 271 (as shown in Fig. 10) to have the top 274 of the engaging strip 27 engaged again in the engaging groove 31. Thereby, the lock core 20 cannot be rotated in the cylinder 30, and locking state is obtained.
