DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a circle lock to which an embodiment of the present invention is assembled, FIG. 2 is an enlarged exploded perspective view of a mounting bracket, and FIG. 3 is an elevation view illustrating a mounting state to a fork.

In the figure, 1 is a circle lock body, 2
Are disposed on the left and right sides of the back surface of the lock body 1, and are fixed at both ends with rivets 3, respectively, and a pair of right and left fixing brackets having an intermediate portion 2 ′ formed in a bridge shape with respect to the riveted portion. Are a pair of left and right band fittings 5 inserted between the intermediate portion 2 ′ of the fixing fitting 2 and the back surface of the lock body 1. It is a resin cover that supports the intersection from the back.

As shown in FIG. 1 and FIG.
A plurality of cutouts 6 are formed on both inner edges in the length direction in a rack shape.
A pair of left and right hooking pieces 8 are provided at the approximate center of the intermediate portion 2 ′, facing downward in the figure, and at the intersection with the band fitting 4,
Are fitted into one of the notches 6, respectively, so that the movement of the belt fitting 4 in the longitudinal direction is disabled, and the central portion of the belt fitting 4 is hooked on the back surface of the intermediate portion 2 '.

As shown in FIG. 2, the cover 5 made of resin is fitted with a fitting piece 9 formed at an end of the fixing fitting 2 with a fitting groove 10 formed on one inner surface thereof. The rivet stoppers can be freely attached and detached, and covered.
The two strips 11 provided on the other side are brought into contact with the back surface of the band fitting 4 as shown in FIG. 1 so that the engagement state of the intersecting portion where the notch 6 and the hook piece 8 are fitted to each other. Hold from behind.

When adjusting the left and right lengths of the band fitting 4 sandwiching the intermediate portion 2 ′ of the fixing fitting 2, the resin cover 5 escapes the fitting groove 10 from the fitting piece 9 of the fixing fitting 2. Then, the holding of the band fitting 4 by the protrusion 11 is released, and the band fitting 4 is separated from the intermediate portion 2 ′ until it comes into contact with the back surface of the lock body 1. Is disengaged, the notch 6 at the desired position is moved to the engagement position with the hook 8 on the back surface of the intermediate portion 2 ', and the notch 6 is again engaged with the hook 8 In this way, the intersection of the band fitting 4 whose length has been adjusted in the left and right direction and the intermediate portion 2 ′ of the fixing fitting 2 is fixed. In addition,

Reference numeral 12 denotes a ridge provided at an appropriate position on the inner surface of the band fitting 4 in contact with the fork. This ridge 12
As shown in FIG. 3, the band fitting 4 wound around the fork F
Is provided to prevent the painted surface from being unnecessarily damaged when tightened to the fork F by screwing the mounting screw 14 through the screw holes 13 at both ends. By interposing between the inner surface and the fork F to partially generate pressure contact between the two members, the painted surface can be prevented from being damaged over the entire width of the band metal fitting 4, and the band metal fitting at the time of screw tightening can be prevented. By forming a tension between the fork 4 and the fork F, thereby tightening the band fitting 4 while tightening it, a strong attachment can be achieved.

When attaching a bicycle lock to Hawk F,
If the length of the band fitting 4 is made equal on the left and right, the screwing position of the mounting fitting is directly below. When the set screw 14 is inserted into the screw hole 13 just below the mounting position, it is dangerous if the tip of the set screw 14 approaches the rotating surface of the tire. Depending on the model, the distance between the forks is narrow or the forks are thin,
There is a possibility that the tip of the set screw 14 may be too close to the rotating surface of the tire.

Conventionally, this has been achieved by using a mounting bracket having a different band portion length depending on the type of vehicle to be mounted. However, the length of the band bracket 4 can be adjusted left and right as in the present invention. By doing so, as shown in FIG. 3, the screwing position can be shifted to the outside of the fork and the position of the tip of the projecting screw can be retracted, so that a sufficient space is formed between the set screw and the tire. Will be able to In FIG. 3, the screwing position indicated by a solid line indicates the screwing position of the left mounting bracket of the lock body 1, and the imaginary line indicates the screwing position of the right fork mounting bracket.

[0017]

According to the present invention constructed as described above and used as described above, by adjusting the fixed length of the mounting band, the difference in the thickness of the fork and the opening of the left and right forks can be obtained. The screwing position of the mounting bracket can be changed according to the difference in the interval. Therefore, there is no need to manufacture mounting brackets with mounting bands that differ in length depending on the type of bicycle, reducing the cost of the bicycle lock itself and adjusting the screwing position,
There is an excellent effect that a safe bicycle lock having a sufficient margin can be attached between the tip of the set screw and the rotating surface of the tire.
