Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus provided with a fixture for mounting on a safety hat such as a helmet. The helmet may be any helmet with perforations that encourage perspiration and ventilation, and the following description uses a bicycle helmet as an example.

[0002]

2. Description of the Related Art Bicycles are originally equipped with power-generating lighting fixtures, but are installed so as to mainly illuminate the traveling direction, so that they cannot respond immediately to other directions.
For example, when something is approaching from the side while riding a bicycle, even if you look at it, you cannot immediately illuminate the object with the lighting equipment of the bicycle.

[0003] In order to solve this problem, lighting equipment is mounted on a helmet. This method includes:
Either the lighting equipment is directly attached with a telescopic belt, or the light emitting part is attached to a protective hat such as a helmet, and the power supply part is attached to the body and connected with a cable.

[0004]

The head-mounted luminaire is easy to use because the line of sight and the optical axis are easily aligned and both hands are free.
However, conventional lighting fixtures are liable to shift or fall off the optical axis depending on how they are mounted on the helmet.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a lighting fixture which can be detachably mounted by using a hole of a helmet.

According to the present invention, an attaching / detaching portion of a lighting fixture and a fixing portion to a predetermined mounting place are connected, and the attaching / detaching portion is formed as a sliding portion by combining a groove of the lighting fixture with a detachable base. The structure has a structure in which the engaging projection and the engaging hole are built in, and when the lighting fixture is moved, the engaging projection and the engaging hole are separated from each other so that the lighting fixture can be attached and detached. The fixed base is placed on the mounting base according to the above, and the fixed base and the detachable base are connected by the engaging hooks and the engaging holes, each of which has a built-in base, and the fixed base is provided with connecting means to the mounting place. It is a lighting fixture provided with a fixture to a helmet.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a lighting device which is detachably mounted on a helmet having holes for promoting perspiration and ventilation through a mounting tool. The attachment was designed for a helmet that protects the head of a person riding a competition bicycle or a mountaineer, and the attachment can be attached to and detached from both the lighting equipment and the helmet.

[0008] The mounting fixture is formed by forming a sliding portion with a groove on the lighting fixture side and a detachable mounting table, and has an engaging hole and an engaging projection in the same portion. When the luminaire is moved along the groove, the engaging hole and the engaging projection are separated from each other. The fixing portion with the helmet is provided by attaching a belt with a length adjusting function to a fixing base provided with a mounting base corresponding to the outer shape of the helmet, and fixing the helmet including the connection base through the belt through the vent hole. Therefore, the lighting fixture can be easily attached to and detached from the helmet, and the utility value for other uses has expanded.

[0009]

According to the present invention, a lighting device can be easily and reliably connected to a helmet.

The lighting fixture side is provided with a groove 13 which abuts with a dovetail 23 of a detachable table 22 on the fixture side and a slide bar 15 with two engaging projections 14 for fixing the detachable table during movement. The slide bar fits in the groove on the lighting fixture side, prevents it from falling out of the groove by an appropriate method, and moves perpendicular to the direction of insertion into the detachable table (see FIG. 6). The attachment / detachment table side has engagement holes 24 on both sides. The operation when attaching and detaching the lighting fixture by separating the engagement hole and the engagement protrusion will be described later.

The fixing portion to the helmet 1 is configured as follows. The helmet side uses the ventilation hole 2. Fixture 3
On the side, the fixed base 32 and the detachable base 22 are overlapped and connected on a mounting base 41 conforming to the outer shape of the helmet. The mount uses a resilient material such as plastic or elastomer. An engaging hook 33 for connecting the detachable table, a belt hole 34 and an engaging frame 37 for a buckle 46 are provided on the fixing table.

The mounting base 41 has a projection 36 on the side of the fixing base 32 which can be replaced according to the shape of the helmet.
And press-fit. The fixing table and the detachable table 22 are provided with connection holes 26.
