Description

  The present invention relates to a multi-purpose fixed lock used for securing a bicycle to a structure or securing a bicycle-mounted component.

Conventionally, as a bicycle antitheft device, a detent lock for stopping rotation of a front wheel or a rear wheel has been used. Such a detent lock is attached to a bicycle frame or a front wheel fork, for example, as shown in the following patent document. As the non-rotating lock, a cylinder lock or the like is usually used. Furthermore, when the bicycle is locked to the structure, a method of winding and locking the wire of the wire lock around the bicycle and the structure using a wire lock or the like is employed.
Japanese Patent Laid-Open No. 8-72765

  However, since these non-rotating locks or wire locks each have only one locking mechanism, for example, two or more linkages such as a bicycle body and a bicycle component such as a saddle. The object to be stopped could not be locked at the same time. Furthermore, when the locking lock and the wire lock are used in combination, each key is required for unlocking. Thus, in order to avoid the complexity of unlocking the locking lock and the wire lock with two keys, for example, the wire lock may be a so-called number lock.

However, in the case of number locks, unlocking in a dark place such as at night is difficult, and in general, the unlocking operation takes time.
In addition, the anti-rotation lock is often attached near the front or rear wheel to stop the rotation of the front or rear wheel. In that case, water or mud splashed by the front or rear wheel of the bicycle is prevented from rotating. It may become easy to adhere to the lock. As a result, there is a possibility that mud is clogged in the keyhole of the non-rotating lock, and rust is likely to be generated on the metal portion of the non-rotating lock.

  The present invention has been made in view of such circumstances, and its purpose is to lock the front wheel or rear wheel of the bicycle, to lock the bicycle to the structure, and to lock the bicycle-mounted components to the main body. It is an object of the present invention to provide a detachable multipurpose fixed lock having a function capable of being locked together.

  In order to achieve the above object, the present invention provides a lock main body having a plurality of lock mechanisms, engagement means for detachably engaging the lock main body with a locked object, and the locked object. Locking means for locking the lock body to the locked body by the locking mechanism, and the locking mechanism is configured to lock the locking body when the locking means engages the locked body. When the means can be locked to the lock body, and the engagement means causes the lock body to be detached from the object to be locked, the locking means cannot be locked to the lock body. This is a multi-purpose fixed lock.

  If comprised in this way, the rotation means will stop rotation of the front wheel or the rear wheel of the bicycle by the locking means using the plurality of lock mechanisms of the lock body, and the bicycle will be locked to the structure. Can be locked to the lock mechanism of the lock body.

  Further, when the bicycle is locked to the lock body, the locking means can be locked to the lock body, and when the lock body is detached from the bicycle, the locking means is locked to the lock body. Since this is impossible, the bicycle and the bicycle-mounted parts can be locked and unlocked easily in a short time.

The locking means may include a terminal inserted into the lock mechanism of the lock body, and may be attached to at least one end of a bendable wire rope.
If comprised in that way, the routing route of the wire rope from the said lock main body to a to-be-tethered object can be chosen freely.

The locking means may include a terminal inserted into the lock mechanism of the lock body, and may be attached to a part of a battery light mounted on the bicycle.
Then, the locking means attached to a part of the battery light mounted on the bicycle is locked to the lock mechanism of the lock body, thereby preventing the battery light mounted on the bicycle from being stolen.

The locking means may include a terminal that is inserted into the lock mechanism of the lock body, and may be attached to a part of a bicycle accessory compartment.
As a result, the locking means attached to a part of the bicycle compartment accessory can be secured to the lock mechanism of the lock body, thereby preventing the bicycle accessory compartment from being stolen.

The lock body may be attachable to a bicycle frame.
If comprised in that way, the water and mud which the front wheel or rear wheel of the bicycle bounced up will not adhere to the lock body. Therefore, there is no possibility that the lock hole of the lock body is clogged with mud or the metal part of the lock body is rusted. Furthermore, the operator can perform the engagement / disengagement work of the lock body with respect to the bicycle and the work of locking or releasing the wire rope to the lock body in an easy posture while standing.

Next, a method of using the multipurpose fixed lock 1 will be described with reference to FIGS.
First, as shown in FIG. 5, the attachment 80 is attached to the frame 102 of the bicycle. In order to attach the attachment 80 to the bicycle frame 102, the band 90 is wound around the bicycle frame 102. The band 90 is a rectangular band plate and has a curvature that is substantially equal to the outer peripheral surface of the frame 102 of the bicycle. At both ends of the band 90, flanges 92a and 92b are formed. The flange 92a is overlaid on the flange 92b, the attachment 80 is overlaid thereon, the bolt 96 is inserted from the opening 84b provided in the support portion 84 of the attachment 80, and the bolt hole 94a of the flange 92a and the bolt of the flange 92b are inserted. The hole 94b is penetrated and screwed with a nut 98 disposed inside the flange 92b. The band 90 can be made of a metal such as steel.

A state in which the attachment 80 is attached to the bicycle frame 102 is shown in FIG.
Next, the lock body 2 is engaged with the attachment 80. That is, the fitting rib 18 provided on the back case 14 of the lock main body 2 shown in FIG. 1A is fitted to the support portion 84 of the attachment 80 shown in FIG. At that time, the locking member 22 of the lock body 2 is inserted into the receiving portion 84 a through the opening 84 b of the support portion 84 of the attachment 80.

  Thereafter, a key is inserted into the keyhole 8 of the cylinder lock 24 and rotated about 45 degrees clockwise or counterclockwise. As a result, the cam 26 in the cylinder lock 24 rotates, and the locking member 22 connected to the cam 26 rotates about 45 degrees. Then, as indicated by the hatched portion in FIG. 4, the locking member 22 meshes with the support portion 84 that defines the opening portion 84b, thereby producing the meshing portion 22a. As a result, the lock body 2 is engaged with the attachment 80.

  At the same time, as shown in FIG. 2B, the lock lever 34 of the lock mechanism 30 is urged by the spring 36, and the tip of the lock lever 34 is inserted inside the terminal guide 32.

  In this state, when the terminal 76 is inserted from the insertion port 16a of the lock body 2 with the grip 74 of the wire rope 70 and the terminal 76 is brought into contact with the guide bottom surface 32b against the biasing force of the spring 36, the terminal 76 is engaged with the lock lever 34, and the wire rope 70 is locked to the lock mechanism 30. Similarly for the other three lock mechanisms, the terminal of the wire rope is engaged with the lock lever, and the wire rope is locked to the lock mechanism.

  Thus, engaging the lock body 2 with the attachment 80 and making the lock mechanism 30 connect the terminal 76 of the wire rope 70 to the lock body 2 are inserted into the keyhole 8 of the cylinder lock 24. Since it is performed at the same time by the rotation of the key, the locked object can be locked or unlocked easily in a short time.

A procedure for releasing the wire rope will be described with reference to FIG.
In FIG. 3, to unlock the wire rope 60, a key is inserted into the key hole 8 of the cylinder lock 24, and further rotated by about 45 degrees clockwise or counterclockwise. As a result, as shown in FIG. 3, the cam 26 rotates and the pin 28b compresses the spring 36 against its urging force and moves the lock lever end surface 34a of the lock lever 34 in the RH direction of FIG. Thereby, the lock lever 34 is pushed out from the terminal guide 32 to the outside (RH direction side in FIG. 3). Then, since the connection between the terminal 66 at the bottom of the hemisphere of the wire rope 60 and the lock lever 34 is released, the wire rope 60 can be pulled out from the terminal guide 32 and the insertion port 16a. Similarly, the other three lock mechanisms are unlocked from the wire rope terminals and can be pulled out from the respective terminal guides and insertion openings.

  At the same time, the engagement by the engagement portion 22a that has occurred between the engagement member 22 of the lock body 2 and the opening 84b of the support portion 84 of the attachment 80 is released by the rotation of the engagement member 22.
