Description

[Detailed Description of the Invention] The present invention relates to a lock that locks a wheel of a bicycle or two-wheeled motor vehicle by passing a wire or a check 7 through the wheel.

In the embodiment shown in the drawings, reference numeral 1 is a horizontally elongated body, and reference numeral 1 is a horizontally elongated body, with a cavity 2 extending over the entire length S being punched out from the right end surface (referred to as the front surface), and a lock hole 3 being opened near the left end of the side surface to communicate with the inner part of the cavity 2. One end of a wire 5 having a length of about 40 cm is fitted into the cylindrical portion 4 protruding from the left end and joined together by a press.

Reference numeral 6 designates a short lock rod to be inserted into the lock hole 3, and has a narrow part 7 with a tapered surface and a head piece 8 following this. The other end of the wire 5 is fitted into the core hole 9 of the lock, and they are joined together with a press.A plastic tube 10 is then placed over the entire length of the cylindrical part 4 of the body and the wire 5, and a rubber ring 11 is fitted into the circumferential groove of the lock lever. This prevents the tube 10 from coming off.

S is an electronic lock, and a lock body 12 having a core hole 13 is inserted into the front part of the cavity 2, and the lock body is fixed to the body 1 with a knock pin 14.

Numeral 15 is a dish-shaped lock plate, which has a round protrusion 16 at the center of the front surface and a small protrusion 17 directed inward at the peripheral edge of the flange. 13, insert the dowel pin 20 driven into the loose-fit waist lock body into the fan-shaped groove 2 of the core rod.
1 to stop the lock plate 15 from being removed.

The lock body 12 has a hollow space 22 formed by punching out its inner half, and five blind holes 23 are equally spaced on a circular line on the front surface, and a spring 24 and a small magnet 25 are inserted into each blind hole. , a part of the magnet is pushed into the recess 26 provided on the back of the lock plate 15, and this magnet connects the lock plate 15 to the lock body 12 to prevent rotation of the lock plate, and the number of magnets 25 and the magnetic pole are Make key differences by changing the direction.

27 is a protrusion provided on the back side of the lock plate 15, which
The lock plate 15 is fitted into the fan-shaped groove 28 cut out on the front periphery of the lock plate 15.
The rotation angle of the magnets 25 is restricted to be below the distribution angle of the magnets 25.

K is an electronic lock key, which consists of a disk 30 that is stacked on the lock plate 15 and stored within its rim, and a grip 31 that gradually becomes narrower and continuous on the back side of the disk, with a recess 32 and a notch 33 in the disk.
are engaged with the protrusions 16 and 17 of the lock plate, respectively, to regulate the position of use.

In this key, five magnets 34 are embedded in a disc 30 at equal angles on a circular line, and these magnets are arranged so that the magnetic poles of the same sex face the magnet 25 in the lock body, and the disc 30 is locked. When stacked on the plate 15, the magnet 25 in the lock body moves out of the recess 26 of the lock plate due to the repulsion of the magnetic poles, allowing the lock plate 15 to rotate.

Reference numeral 35 denotes a relay body that fits between the middle part of the cavity 2 of the body and the cavity 22 of the lock body, and fits into the square hole 36 on the front face with the corner end 19 of the core rod of the lock plate so that it is connected to the lock plate 15. combined with
Two annular slope cams 37 are formed on the periphery of the back surface, and a thick core shaft 38 is provided at the center of the back surface to protrude beyond the slope cams 37.

Reference numeral 40 denotes a locking tube inserted into the inner part of the cavity 2 of the body, and the protrusions 41 and 4m on both side edges are placed in the side grooves 42 and 42 of the cavity to prevent rotation, and the rear end and the inner end of the cavity 2 are prevented from rotating. A ten-shaped return spring 43 made of bamboo is inserted in between, and the locking hole 44 that receives the pincer part 7 and the head piece 8 of the lock rod is punched out from the bottom surface, and the corner of the locking hole is pressed. The head piece 8 is hooked on the edge 45 to stop the lock rod 6 from being pulled out.

This locking cylinder 40 has a core shaft 38 of a relay body inserted into a through hole 46 made on the electronic lock side, so that its end edge can be seen through the locking hole 44, and two slanted cams 47. 47 is formed into an annular shape, and the sloped cams 37 and 37 of the relay body are fitted therein.

In this case, the locking tube 40 is constantly pressed by the return spring 43 to bring the slope cams 47.47 into close contact with the slope cams 37.37 of the relay body, and is prevented from rotating by the projections 41, 41, so that the locking hole 44 is closed to the body. When the lock plate 15 is turned toward the lock hole 3, the inclined cam 37 of the relay body pushes the lock tube 40, and the corner edge 45 of the lock hole is set so as to be disengaged from the head piece 8 of the lock rod.

In addition, the locking hole 44 is made to be a long hole in the front and rear direction in consideration of the amount of retraction of the locking cylinder 40.

One embodiment of the present invention has the above structure, and when the wire 5 is passed through the wheel of the bicycle and the lock rod 6 is inserted into the lock hole 3 of the body, the head piece 8 of the lock rod 6 hits the slope of the lock hole 44. When the locking cylinder 40 is moved backward against the return spring 43 and the lock lever is pushed in fully, the locking cylinder 40 returns with the elasticity of the return spring 43 and locks the pincer part 7 and the head piece 8. It is inserted into the hole 44, and the corner edge 45 of the locking hole is hooked on the back surface of the head piece 8 to lock the lock rod 6.

When inserting the lock rod 6 into the lock hole 3 of the body, the electronic lock side of the head piece 8 rubs against the edge of the core shaft 38 of the relay body, so the lock rod 6 is forced into the corner edge 45 of the lock hole. It enters the locking hole 44 straight without any problems.

When unlocking, when the key disc 30 is placed on the lock plate 15, the magnet 25 in the lock body moves out of the recess 26 of the lock plate due to the repulsion of the magnetic poles, making the lock plate 15 free to rotate.

Then, when the key K is turned, the lock plate rotates together with the relay body 35, and the slope cam 37 of this turns the locking tube 40 by the slope cam 47.
The corner edge 45 of the locking hole is removed from the head piece 8 of the lock rod, so that the lock rod 6 can be removed.

When the key K is then removed, the locking cylinder 40 returns to its original position by the elastic force of the return spring 43, and the inclined cam 47 rotates the relay body 35 to return the relay body and the lock plate 15 to their initial positions.

The above describes one embodiment of the present invention, but the present invention is not limited to this embodiment, and the design can be changed within the spirit of the invention. For example, a chino may be used instead of a wire.

In the present invention, the entire length of the body is punched out, the main body of the electronic lock, the relay body, the locking tube, and the return spring are inserted, and a lock hole is drilled near the side end of the body and the lock rod is inserted. The head piece of the lock rod is configured to be locked by hooking it on the locking cylinder, and the electronic lock can be incorporated into a wire or chain type lock to significantly reduce the overall size. It is possible to securely lock the lock by hooking it on the locking cylinder, and it has the advantage of being easier to unlock than a number combination lock, and has the effect of providing a wire or chain type lock that is durable, easy to use, and has a good appearance. has.
