Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a power generating device for use in a bicycle.

(b) Prior art The conventional method of attaching a generator to a bicycle is as disclosed in Japanese Patent Publication No. 57-59110, for example.
This was done by simply holding the upper mounting member and the lower mounting member between the backhoes, but with this configuration it was difficult to position the dynamo so that it was in pressure contact with the center of the outer circumferential surface of the tire, and the bicycle During use, the upper and lower mounting portions slide back and forth, resulting in the disadvantage that the dynamo does not come into secure pressure contact with the tire.

(c) Problems to be Solved by the Invention The present invention has been made in view of these points, and provides a power generation device in which the generator does not shift its position during use.

(d) Means for solving the problem The present invention has a pair of locking pieces on the left and right sides of the upper mounting member that locks on the back hawk, a hook piece on the rear end that locks on the tire house support piece, and a hook piece on the front end that locks on the tire house support piece. A hanging piece is formed on the lower mounting member to be engaged with a recess formed on the upper surface of the lower mounting member.

(E) Function This prevents the generator fixed to the upper mounting member from shifting.

(f) Embodiment 1 The rear wheel constitutes a part of the bicycle body, and is rotatably supported by a pair of backhawks 2, 2. Reference numeral 3 denotes a semicircular tire house that protects the upper outer periphery of the tire 4 constituting the rear wheel 1 at a distance, and the front lower part of the house 3 protects the upper outer periphery of the tire 4 constituting the rear wheel 1.
It is fixedly supported by screws 6 to an elongated tire house support rod 5 suspended between the two.

7 is a screw hole 8 through which the fixing screw 13 is inserted in the center.
A pair of locking pieces 9, 9 that lock onto the top surface of the back hawks 2, 2 are provided on the left and right sides (both sides) of the top mounting member, and a pair of locking pieces 9, 9 that lock onto the top surface of the tire house support rod 5 are provided on the rear end of the upper mounting member. A pair of hooking pieces 10, 10 for locking
A hanging piece 11 is formed at the front end thereof and is bent downward.

Reference numeral 14 denotes a lower mounting member which is tightened and clamped from below between the backhawks 2 and 2 together with the upper mounting member 7, and has another screw hole 15 opposite to the screw hole 8 formed in the center of the upper surface, and screw holes 15 on both upper edges thereof. is a locking curved surface 1 that engages the lower surface of the back hawks 2, 2.
6, 16, and the hanging piece 11 is formed on the front part of the upper surface.
A recess 18 for locking is formed.

A cylindrical generator 20 is rotatably attached to the lower part of the lower mounting member 14 via a pair of left and right arm rods 21, and is pressed against the tire lead surface 4a of the tire 4 by the operation of the operating rod 22. . 24
is a mudguard suspended from the lower mounting member 14.

With such a configuration, movement of the upper mounting member 7 in the left and right directions is prevented by the hook pieces 10, 10 and the locking pieces 9, 9, and movement of the lower mounting member 14 in the left and right directions is prevented by the hanging pieces 1.
1, and as a result, once the contact state between the generator 20 and the tire lead surface 4a is adjusted, it is always maintained in the same state, and there is no rattling during use, and its installation is extremely simple.

(f) Effects of the invention Since the invention is constructed as described above,
The upper mounting member is firmly fixed between the backhawks,
As a result, the positioning interval between the generator and the tire during use is ensured.
