Description

  The present invention relates to a portable locking device.

  In a portable locking device, as disclosed in Patent Document 1, a substantially U-shaped bar is passed through a locked object and then locked by locking a substantially I-shaped bar on both ends of the U-shaped bar. As disclosed in Document 2, what is locked by passing a wire through a locked object and then locking the wire in a loop shape is well known.

  Further, as in Patent Document 3 or 4, there has been known an idea of a lock using a wire that can be stored in a casing and one end is fixed in the casing.

JP 2000-053046 A Japanese Utility Model Publication No. 63-0667168

The locking device is desired to have a sturdy appearance and to eliminate the willingness of a malicious third party to steal the locked object.
In addition, a locking device having a long wire or the like is desired in order to lock the locked object so as to be connected to the gate pillar and the like so that the locked object is not easily moved.
However, many of these locking devices designed to prevent theft are difficult to carry. For example, a bicycle without a basket, such as a sports-type bicycle, can be hung on the steering wheel while driving a locking device that seems to be sturdy. I often see it. Such a portable method hinders the operation of the steering wheel, and in a sport-type bicycle in which the frame is thinned with aluminum or carbon and beautifully painted, it is difficult for the locking device that moves gently to damage the frame. However, if it takes time to fold and store when the locking device is not used, it will take time to use it and the locking will be neglected.

  Embodiments of the present invention will be described below with reference to the drawings and the like, but this is intended to make the contents of the present invention easier to understand, and does not reduce the scope of the appended claims.

The portable locking device according to the first aspect of the invention is, for example, as shown in FIGS.
An end 1 comprising a fitting shape 8 (9) and a lock body 5 comprising a locking piece 10 movable inside;
An end portion 2 including a fitting shape 12 and a locked portion 15 that can be locked by the locking piece 10 being engaged;
One end and the other end are connected to end portions 1 and 2, respectively, and a wire portion 3 that is preliminarily formed into a cylindrical coil shape,
A locking device 4 comprising:
Fitting shapes 53 and 54 which are fitted to the fitting shape 8 (9) and the fitting shape 12, respectively, and are held so as to be removable.
The inner wall 59 that is provided between the fitting shapes 53 and 54 and is rod-shaped and viewed in the axial direction is substantially C-shaped, and the wire portion 3 is inserted into the inner wall 59 from the insertion port 60 between both ends of the substantially C-shape. A wire storage 61 that can be inserted inside;
A holding member 50 comprising:
It is a portable locking device.

The portable locking device according to the second aspect of the invention is the locking device of the first aspect of the invention, for example, as shown in any of FIGS.
The holding member 50 is a portable locking device including attachment means 62 that can be fixed so that the rod-shaped wire storage portion 61 is snuggled against the rod-shaped portion of a moving body such as a bicycle or a motorcycle.

The portable locking device according to the invention 3 is the locking device of the invention 2,
The attaching means 62 is a belt-like part provided integrally or separately with the holding member 50,
The band-shaped portion is a portable locking device that can be wound around the rod-shaped portion of the moving body.
For example, in any of FIGS. 3, 6, and 8, the belt-shaped member is passed through the hole 58 and along the groove 57, and then wound around the rod-shaped portion of the moving body.

A portable locking device according to a fourth aspect of the invention is the locking device of the first aspect of the invention, for example, as shown in any of FIGS.
The holding member 50 is a portable locking device that includes holes 55 and 56 that match the mounting pitch of the screw holes for mounting the drink holder of the bicycle frame.

  As described above, in the present invention, when using the locking device 4, unlike the locking device of Patent Document 3 or 4, the holding member 50, which is a casing, can be quickly removed. The wire that could not be used can be effectively used, and the movement of the locked object can be effectively prevented by the wire portion 3 having a sufficient length. In addition, it is difficult to cause inconvenience that dust attached to the wire part 3 cannot be cleaned by being pulled into the casing when used outdoors. Further, when the locking device 4 is stored in the holding member 50, if the wire portion 3 is extended as shown in FIG. 1, the outer diameter of the cylindrical coil shape is reduced, so the wire portion 30 is easily stored from the insertion port 60. In addition, since the outer diameter returns to the original state after storage, it is easy to suppress the backlash of the wire portion 3 inside the wire storage portion 61.

Further, in the invention 2 or 3, in addition to the effect of the present invention, for example, if the rod-shaped wire storage portion 61 is arranged so as to snuggle up to the frame pipe of the bicycle frame and the locking device 4 is stored, the lock device 4 can be stored quickly. Since the locking device 4 can be used, the possibility of causing a burden or damage to the bicycle frame is reduced, and the bicycle operation is not hindered.

In addition, in the invention 4, in addition to the effect of the present invention, the holding member 50 is attached by using, for example, a screw hole for attaching a drink holder provided in advance in a bottom tube or a seat tube of a bicycle frame, and the drink bottle and the frame pipe If the locking device 4 is stored so as to snuggle up, the locking device 4 can be used quickly at the time of use, and the possibility of causing a burden or damage to the bicycle frame is reduced, and the bicycle operation is not hindered.

Further, as shown in FIG. 9, the holding member 50 is provided with a wire storage portion 61 having a substantially C-shaped section AA in FIG. 3, and the cylindrical coil shape of the wire portion 3 is inserted with a slight resistance. Thus, when the locking device 4 is stored, the wire portion 3 is less likely to rattle due to vibration or the like.
If there are no clues for attaching screw holes or the like on the rod-shaped portion of the moving body, a band-shaped member such as a band for bundling the electric wires is passed through the hole 58 and along the groove 57 before the rod-shaped portion of the moving body. A method of fixing by wrapping around can be considered. Further, the holding member 50 may be provided with a band-shaped portion in advance.
