A base consisting of a vertical part provided with a shaft support hole, a horizontally movable movable shaft member provided across the shaft support holes of each vertical part of this base, and a vertical part between the vertical parts. A movable plate with screw holes attached to the movable shaft member at both ends so as to be perpendicular to the vertical portion, and a movable plate with screw holes inserted through the holes in the upright piece of the base and whose ends are screws of the movable plate. an adjustment screw that is adjustably screwed into the hole; a first fixed arm that has one end inserted through and attached between the screw head of the adjustment screw and the upright piece insertion portion of the base; and one end that is rotated around the movable shaft member. a second fixed arm that is rotatably supported and whose other end constitutes a locking mechanism together with the other end of the first fixed arm, and a state in which both ends are fixed between upper ends of the respective vertical parts of the base; The present invention relates to a mounting tool for a bicycle lighting device, which comprises a positioning pin that is attached to the bicycle and spans over the space, and that comes into contact with the inside of the second fixing arm to position the second fixing arm during installation.

Bicycle lighting fixtures are generally installed using two curved arms that sandwich part of the bicycle's pipe, but this method cannot be used when the bicycle's pipe is quite thin or thick. is the current situation.

This invention was made in view of the above points, and provides a fitting that incorporates an adjustment mechanism for the inner circumferential dimension so that it can be used regardless of whether the diameter of the pipe is large or small.

This invention will be explained in detail below using example drawings.
This invention is not limited to the following examples.

FIGS. 1, 2, 3, and 4 are a perspective view (inverted upside down position), a front view, a side view, and a rear view, respectively, showing the overall configuration of this invention.

Reference numeral 1 denotes a base, which is constructed by bending an iron plate into a U-shape, and has a horizontal fixing part 2 and a horizontal fixing part 2.
It consists of vertical parts 3, 3 rising from opposing positions on both sides. The lower surface (the upper surface in the actual installation state) of the horizontal fixing portion 2 is fixed to the lower surface of the bottom of the lighting device, and this fixture is integrally attached to the lighting device. An upright piece 5 having a through hole 4 is provided in the horizontal fixing portion 2 in a direction perpendicular to the vertical portions 3, 3, and a horizontally long shaft support hole 6 is provided in the vertical portions 3, 3 at opposing positions. . Reference numeral 7 denotes a movable shaft member, and both ends thereof are fitted into the shaft support hole 6 so as to be movable in the horizontal direction. 8, 8 are fixed, and the vertical parts 3, 8 are fixed between the vertical parts 3, 3.
A moving plate 9 is provided so as to be positioned in a direction orthogonal to 3. This movable plate 9 horizontally moves together with the fixed movable shaft member 7. The bent fixing parts 8, 8 of the movable plate 9 function to stably accommodate both ends of the movable shaft member 7 in the shaft support hole 6, and furthermore, a screw hole 10 is provided in the center of the movable plate 9. 11 is an adjustment screw,
It is inserted through the through hole 4 of the upright piece 5 of the base 1, and its end is screwed into the screw hole 10 of the movable plate 9. 12 is a first fixed arm;
Reference numeral 3 designates a second fixed arm, both of which have inner surfaces curved to follow the shape of the pipe of the bicycle. A through hole 14 is provided at one end of the first fixed arm, and this through hole 14 portion is connected to the adjustment screw 1.
It is inserted between the insertion part of the upright piece 5 of No. 1 and the screw head 15 and attached. One end of the second fixed arm 12 has a branched shape and is formed into a cylindrical shaft support 16, in which the movable plate 9 of the movable shaft member 7 is connected between the bent and fixed parts 8, 8. It is attached so that the part can be inserted through it. and the first fixed arm 1
2 and the second fixed arm 13 are provided with a locking portion 17 and a locked portion 18, respectively.
7 and 18 constitute a conventionally known one-touch locking mechanism. The positioning pin 19 is the base 1
Between the upper end (lower side when attached to a pipe) of each vertical part 3, 3, that is,
It is installed in a fixed state over the end of the shaft support hole 6 in the opposite direction to the side where the screw head 15 of the adjustment screw 11 exists, and when it is attached to the pipe, the second fixed arm 13 is abutting the inside, the second
The fixed arm 13 is positioned.

The adjustment mechanism during installation using the adjustment screw 11 will be described below.

First, the first and second fixing arms 12, 13 are temporarily attached to the pipe to be attached, and at this stage it is determined whether to widen or narrow the two fixing arms 12, 13. If it is to be narrowed, the adjusting screw 11 is screwed in, and the end of the adjusting screw 11 protrudes further from the movable plate 9. In other words, when installing, the screw head 15, the first fixing arm 12
One end and the upright portion 5 come into contact with each other, and by screwing in the adjustment screw 11, the movable plate 9, together with the movable shaft member 7 and the end of the second fixed arm 13, comes into contact with the above three abutting portions. As a result, the distance between the ends of both fixed arms 12 and 13 is narrowed. The mounting inner circumferential dimension of this attachment is the sum of the inner dimension of both fixed arms 12, 13 and the distance between the ends of both fixed arms 12, 13, so the adjustment screw 11 is screwed into the fixed arms 12, 13. When the distance between the parts is narrowed, the inner circumferential mounting dimension is naturally reduced. To spread it out in the opposite direction, turn the adjustment screw 11 in the opposite direction and tighten both fixed arms 1.
2, 13 Increase the distance between the ends. When installing, the curved recess 20 provided on the upper edge of the vertical parts 3, 3 of the base 1 is aligned with the pipe from above, and the pin 19 abuts on the inside of the second fixing arm 13. , the base 1 is positioned exactly on the pipe 21, and the lighting device 22 is mounted in a weight-balanced state as shown in FIG.

When packing the lighting device, the first fixing arm 12 of this fixture can be laid down horizontally (parallel to the bottom of the lighting device) with the adjustment screw 11 as an axis, so that it does not get in the way and can be stored compactly.

This idea is structured as described above, so
It can be used without any problem even if the diameter of the pipe to which the lighting device is attached differs.
In particular, it is extremely convenient in that adjustment operations can be easily performed using the adjustment screw. In addition, it not only has an adjustment function, but also combines the adjustment function with the positioning pin of the second fixing arm, so that the lighting device can be installed in a well-balanced manner during installation. Furthermore, when packing the lighting device, the first fixing arm is laid down on its side, so there is an advantage that the packing form does not become large.
