Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to a dynamo for a bicycle.

(B) Conventional technology As shown in FIG. 5, a conventional bicycle dynamo has a sheet metal dynamo holder cover (A) attached to the dynamo inclining spring part to prevent mud from sticking to the spring or fingering the spring. Consideration is given to safety and function maintenance so that it will not be pinched, and when installing on the bicycle body,
It was mounted with mounting bolts and mounting nuts, and spring washers 5b, etc. were used as loosening prevention means, or nylon nuts were used.

(C) Problems to be solved by the device Although the dynamo holder cover in these conventional techniques covers the dynamo up and down spring, it is dangerous because the rotating shaft of the working lever and the mounting body remain open. In addition, the mounting nuts, etc. remained exposed, which caused problems in terms of design and aesthetics. Although some measures are taken to prevent the mounting nuts from loosening, loosening due to vibration is unavoidable, and there is a problem that the structure becomes complicated and the cost increases if complete measures are taken.

(D) Means for Solving Problems The present invention has been made to solve these problems, and provides a dynamo having a specific dynamo holder cover that can integrally cover the mounting body. The specific structure is a bicycle including a dynamo main body, a dynamo holder having a spring and a working lever for holding the main body so that the main body can be tilted, and an attachment body for fixing the dynamo holder to the bicycle main body. In the dynamo for use, the dynamo holder and the mounting body are integrally covered, and the window for projecting the operating lever operating protrusion is provided on the front side of the portion covering the dynamo holder, and the window from above the lower side Equipped with a tongue that can be elastically deformed inward by the working lever when the working lever is pushed down A dynamo for a bicycle, wherein a dynamo holder cover is detachably attached.

Further, according to the present invention, there is provided a preferable mode in which the portion of the dynamo holder cover which covers the mounting body is integrated with the portion of the thin wall portion which covers the dynamo holder to form a hinge structure. Further, the present invention provides a dynamo holder cover as a preferred embodiment, in which the mounting body is composed of mounting bolts and mounting nuts, and the portion covering the mounting body has a fitting portion that fits on the outer periphery of the mounting nut. .

(E) Action Since this invention is configured as described above, it is possible to cover the other parts except the dynamo main body with one cover,
In addition, it is preferable to move the part covering the mounting body and the part covering the dynamo holder independently by a hinge structure, and at the same time to prevent loosening of the mounting nut by a specific mating part, at the same time fixing the dynamo holder cover on the mounting body side. Has the effect of

(F) Embodiments The invention will be described in detail with reference to embodiments shown in the drawings. In addition,
This does not limit the invention.

FIG. 1 is a perspective explanatory view before mounting a cover showing an embodiment of the present invention, and FIG. 2 is a front and side (partial cross-sectional) explanatory view after mounting the cover. The bicycle dynamo 100 includes an upright dynamo body 1, a shaft 1a extending vertically from a side wall of the dynamo body 1,
It is composed of a spring 2 including the shaft 1a, a dynamo holder 4 for holding the dynamo main body 1 by the shaft 1a, a working lever 3 on the front of the dynamo holder 4, and a mounting body 5 for mounting on a bicycle. On the other hand, the dynamo holder cover 6 is composed of a part 7 that covers the dynamo holder and a part 8 that covers the mounting body. The part 7 that covers the dynamo holder is the shaft 1 of the bicycle dynamo 100.
A part of the dynamo holder 4 including a and 3b and the working lever 3 is covered with a snap. In addition, a window 3a is opened on the front side of the portion 7 that covers the dynamo holder.
A tongue 9 that extends upward from the lower side and whose tip can be elastically deformed inward by the working lever 3 when the working lever 3 is pushed down is projected. The operating projection of the working lever 3 can be projected through the window 3a to the front of the dynamo holder cover 6. On the other hand, since the mounting body 5 has a structure in which the mounting body 5 extends obliquely downward from the dynamo holder 4, the portion 8 covering the mounting body extends obliquely downward from the portion 7 covering the dynamo holder, and the mounting body 5 is also mounted. It is designed to cover Supori. Furthermore, a hooking portion 7a is integrally formed on the upper edge of the opening 7 of the portion 7 that covers the dynamo holder.
It controls the positioning and fixing of the dynamo holder cover 6 together with the storage section 10 of. The thickness of the tongue 9 becomes thinner toward the tip, and when the working lever 3 is operated by pushing it down, the tip falls inward, so that the above operation is not hindered (Fig. 3). . When the working lever 3 is returned to its original position, the tongue 9 gradually stands up due to its elasticity and returns to its original state.

FIG. 4 is an explanatory view showing another embodiment. The portion 7 that covers the dynamo holder and the portion 8 that covers the mounting body are integrated (connected) with a thin portion 8 to form a hinge structure, and the portion 8 that covers the mounting body is independently attached and detached as indicated by the arrow. It can be opened and closed. Further, a fitting portion 12 having a polygonal opening for fitting with the mounting nut 5a is provided in the portion 8 which covers the mounting body, and a notch portion 13 is provided in one side wall of the fitting portion 12. ing. This is provided so that the mounting nut 5a can be easily fitted into the fitting portion 12 when the hinge structure is provided. These other embodiments may be carried out alone or simultaneously if desired. The holder cover provided on the dynamo of the present invention may be made of metal, but is preferably made of rubber or plastic. Alternatively, the holder cover provided in the dynamo of the present invention may be used alone, or may be used in double over the holder cover.

(G) Effect of the invention As described above, in the invention, since the dynamo holder cover is configured to integrally cover the dynamo holder and the mounting body, rainwater can be applied to the dynamo tilting spring and the mounting bolts and nuts. Not only can they be prevented from corroding due to muddy water or muddy water, but also the risk of injury from fingers hitting the protrusions or corners of the mounting bolts and nuts when operating the working lever. You can Furthermore, on the front side of the part of the dynamo holder cover that covers the dynamo holder, there is a window for projecting the operating lever operating protrusion and a window extending upward from the lower side of this window to allow the working lever to be pushed down when the working lever is pushed down. Since the tip has a tongue that can be elastically deformed inward, the operation of the working lever can be performed without any hindrance, and the window is partially blocked by the tongue when the working lever is not operated. The effect of preventing corrosion can be more reliably exhibited. Further, if the cover itself is configured to be fitted with the mounting nut, it has two effects of fixing the cover and preventing the nut from loosening at the same time, and has a design effect and a cost reduction effect by integral molding.
