Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a handle member mounting structure for a toy motorcycle, in which a handle member is attached to a front wheel steering shaft.

(Prior Art) Conventionally, in this type of handle member mounting structure for a toy motorcycle, the tip of the front wheel steering shaft is simply brought into contact with the back side of the handle member and fixed with a screw. However, with this mounting structure, there is a problem that the handle member and the front wheel steering shaft rotate independently, and a solution to this problem has been desired.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned points of view, and particularly provides a handle member mounting structure for a toy motorcycle that allows the handle member to be easily attached to the front wheel steering shaft. The purpose is to make suggestions.

(Technical means for solving the problem) As a technical means for solving the above problem, a handle member mounting structure for a motorcycle toy according to the present invention is characterized by having a handle having the following configuration. .

(a) A through hole is formed at the front end of the body member of the motorcycle toy, a steering shaft of the front wheel is rotatably inserted into the through hole, and a handle member is attached to the upper end of the steering shaft. That's what I'm doing.

(b) A screw hole is formed vertically through the center of the handle member, and an engagement recess with a semi-cylindrical cross section is formed at the lower peripheral edge of the inner wall of the screw hole.

(c) A screw receiving hole is formed at the center of the upper part of the steering shaft of the front wheel, and an engaging part having a semi-cylindrical cross section that engages with the engaging recess is formed protruding from the upper edge of the screw receiving hole. is being done.

(d) The screw inserted through the screw hole of the handle member must be screwed into the screw receiving hole of the steering shaft of the front wheel.

(Operations and effects of the invention) According to the above structure, the steering shaft of the front wheel is inserted into the through hole of the body member, and the handle member is disposed thereon, so that the engagement recess of the handle member and the steering shaft are engaged. The handle member can be easily attached by engaging the joint portion and further screwing the screw passed through the screw hole of the handle member into the screw receiving hole of the steering shaft. Since the engaging recess of the handle member and the engaging part of the steering shaft are engaged with each other, these two members do not rotate independently of each other, and the steering direction can always be accurately determined by the handle member. .

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral A indicates a motorcycle toy with a handle attached by the toy motorcycle handle member attachment structure according to the present invention. A body member 3 is provided.

A screw hole 6 is vertically formed through the center of the handle member 1, and an engagement recess 5 having a semi-cylindrical cross section is formed at the lower peripheral edge of the inner wall of the screw hole 6.

Further, a front wheel 8 is attached to the lower part of the steering shaft 2 via a support shaft 7, and a screw receiving hole 10 is formed at the center of the upper part. An engaging portion 9 having a semi-cylindrical cross section that engages with the engaging recess 5 is formed in a protruding manner. In addition, 21
is a windshield member.

The body member 3 has a tank portion and a seat portion integrally formed, and has a support portion 3a in the front portion thereof, which has a through hole 11 into which the front wheel steering shaft 2 is rotatably inserted. It is formed. Further, a rear wheel 13 is rotatably attached to the lower rear via a support shaft 12. Furthermore, a drive member a is housed inside the body member 3, and a stand member 14 is rotatably attached to the lower, substantially central portion. As a result, when the motorcycle is stopped, the stand member 14 is erected and the toy motorcycle A is held so that it does not fall down, and when the motorcycle is running, it is set aside.

The drive member a includes a flywheel 15, a spur gear 17 meshed with a pinion 16 arranged coaxially with the flywheel 15, and the spur gear 1.
a spur gear 19 coaxially with the rear wheel 13 meshed with a pinion 18 coaxially arranged in parallel with the rear wheel 13;
It is formed by. As a result, the toy motorcycle can be driven by bringing the rear wheel 13 into contact with the running surface and rotating it vigorously to drive the drive member a.

Next, when attaching the handle member 1 to the front wheel steering shaft, first, the front wheel steering shaft to which the front wheel 8 is rotatably attached is attached to the support portion 3a of the body member 3.
The screw 20 is inserted into the through hole 11 provided in the front wheel steering shaft, and the engagement recess 5 provided on the lower side of the handle member 1 is engaged with the engagement portion 9 formed at the upper end of the front wheel steering shaft. It may be inserted through the screw hole 6 and screwed into the screw receiving hole 10 of the steering shaft 2 to be integrated. As a result, the handle member 1 is firmly fixed to the front wheel steering shaft 2.

According to the above-described configuration, the steering shaft 2 of the front wheel 8 is inserted into the through hole 11 of the body member 3, and the handle member 1 is arranged thereon, so that the engagement recess 5 of the handle member 1 and the steering shaft 2 engaging the engaging portion 9 of the
Furthermore, the handle member 1 can be easily attached by screwing the screw 20 inserted through the screw hole 10 of the handle member 1 into the screw receiving hole 10 of the steering shaft 2. Since the engagement recess 5 of the handle member 1 and the engagement portion 9 of the steering shaft 2 are engaged with each other, these two members do not rotate independently of each other.
The handle member 1 allows the direction of travel to be determined accurately at all times.
