Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is installed on a motorcycle,
This invention relates to a mounting structure for a warning light for a motorcycle that is used in a blinking or continuously lit manner.

0002

[Prior Art] Motorcycles known as "white motorcycles" have traditionally been used by traffic police for patrol purposes, and these types of vehicles are equipped with warning lights that flash or illuminate continuously in the event of an emergency. Generally, the warning light has a pipe bracket-like mounting structure on a rod-shaped bumper of a motorcycle, and as shown in FIG. It has a structure in which it is clamped and fixed tightly with screws 54.

0003

[Problems to be Solved by the Invention] However, according to the above-mentioned warning light mounting structure, since there is no buffer structure between the light fixture body 50 and the bumper 53, vibrations on the motorcycle side directly affect the lighting of the light fixture. This has had the problem of adversely affecting the rotary drive mechanism of the valve and reflector.

The present invention was devised in view of the above-mentioned problems, and provides a motorcycle warning light that absorbs vibration transmission from the bumper, protects the lamp body from vibration, and extends the lifespan. The purpose is to provide a mounting structure.

[0005]

[Means for Solving the Problems] The mounting structure of the motorcycle warning light according to the present invention includes a plurality of lateral compression panels installed horizontally on the lower surface of a base member of a lighting device in which a lighting bulb is covered with a lens globe. The gist is that a mounting structure fixed to an attached part is constructed and supported by a spring and a plurality of vertical compression springs installed vertically, and is elastically biased in a three-dimensional direction.

[0006]

[Operation] According to the above-mentioned mounting structure, the lamp is attached to the base member of the lamp via a horizontal compression spring and a vertical compression spring, forming a three-dimensional buffer structure. Therefore, external vibrations propagating to the lamp body are absorbed, and vibrations of the lamp itself can be suppressed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the mounting structure for a motorcycle warning light according to the present invention will be described below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. FIG. 1 shows a warning light for a motorcycle, which has a mounting structure of the present invention for being fixed to a rod-shaped bumper a of a motorcycle on the bottom surface, and has a mounting structure 2 on the bottom surface of a base member 1. A lighting bulb 4 is replaceably attached to a bulb socket 3 fixed to the center of the upper surface of the base member 1, and a reflector 5 pivotably mounted on the outer periphery of the lighting bulb 4 is pivotally mounted. At the same time, a rotational drive mechanism 6 formed on the upper surface of the base member 1 rotates around the lighting bulb 4. Further, the base member 1 is provided with a bell-shaped lens glove 7 made of a translucent synthetic resin so as to cover the bulb 4 and the like.
is covered to form an airtight lamp chamber 8.

As shown in FIGS. 2 and 3, the mounting structure 2 includes support brackets 9,
9... are protruded from each other, and the bent edges 12, 12... protruded from the outer edge of the receiving bracket 10, which has a fitting groove 11 formed in the center with a concave groove having a semicircular cross section. The springs 13, 13, . . . are tensioned and elastically biased, and vertical compression springs 15, 15, .

Reference numerals 16, 16, . . . designate screw ports whose collar portions are configured to fit into the ends of the vertical compression springs 15, and which have retaining grooves formed with fitting grooves having semicircular cross sections. The fastening screws 18, 18, . . . inserted through the through holes of the bracket 17 are screwed together, and the lamp is fixed by holding the horizontal rod portion of a bumper a of a motorcycle, for example, as shown in FIG.

[0011] The horizontal compression spring 13 and the vertical compression spring 15 constitute a buffer structure in which the mounting structure 2 is supported in a floating manner elastically.

The mounting structure 2 of the motorcycle warning light constructed as described above is used by being fixedly attached to the bumper a of the motorcycle or an accessory bracket. The beam rotates, forming a so-called beacon lamp. In the lamp attached to the bumper a, the receiving bracket 10 and the holding bracket 17 are elastically floating supported by the horizontal compression spring 13 and the vertical compression spring 15, so these springs absorb vibrations in three-dimensional directions, It acts to suppress the vibrations propagating to the base member 1 and reduce the slight vibrations of the lamp body.

FIGS. 4 and 5 show another embodiment of the mounting structure 2, and the structure different from the first embodiment will be explained. That is, this embodiment eliminates the friction noise caused by the lateral compression springs 13, 13, . A protruding shaft 2 protruding from the bent edge 12
A synthetic resin collar 21 is fitted over the synthetic resin collars 19 and 21, and each end of a horizontal compression spring 13 is fitted between the synthetic resin collars 19 and 21, respectively, and is elastically biased.

With the above structure, the synthetic resin collar 19 is placed between the horizontal compression spring 13 and the brackets 9 and 10.
, 21, the metals do not directly rub against each other, and therefore, it is possible to eliminate the rubbing noise during use.

[0015]

[Effects of the Invention] Since the mounting structure of the motorcycle warning light according to the present invention is constructed as described above, a three-dimensional buffer structure is constructed by the horizontal compression spring and the vertical compression spring in the mounting structure of the light fixture. As a result, external vibrations propagated to the lamp body can be absorbed, which has the effect of extending the life of the lamp, and the effects after implementation of the present invention are extremely large.
