Description

[Detailed Description of the Invention] The present invention relates to a horn installed in automobiles, two-wheeled vehicles, etc., and particularly relates to an improvement in its holder.

Conventionally, in order to make a horn sound stably and to prevent the adverse effects of vibrations of the vehicle body, the horn 1 has been made in the form of a plate made of laminated metal spring materials, as shown in FIGS. 1 and 2, for example. It is known that the vehicle body is fixed to a bracket 4 via a holder 2 with bolts 3.

However, in automobiles, the horn 1 is disposed in a limited space in front of the engine compartment, and therefore the problem is that mounting with the bolts 3 is extremely difficult.

Furthermore, when the plate-shaped holder 2 made of metal spring material is used, the housing 1a of the horn 1 becomes at the same potential as the vehicle body (generally the ground potential of the power supply), and the terminal (the terminal on the positive potential side) due to the adhesion of rainwater, etc. , Terminal 5a
Alternatively, leakage current may flow between the terminal 5b) and the housing 1a, resulting in damage to the terminal due to electrolytic corrosion.

The object of the present invention is to eliminate the above-mentioned drawbacks and inconveniences of the prior art, and to provide a holder for a warning horn that is easy to attach to a vehicle body and whose terminal is not damaged by electrolytic corrosion.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in FIGS. 3 to 5.

In the figure, reference numeral 1 denotes a horn having a housing 1a, from which a bolt 6 is protrudingly fixed by welding to the center of the back surface of the housing 1a.

Reference numeral 7 denotes a holder made of a material having elasticity and insulation properties such as rubber or synthetic resin, and the holder 7 has a cross section shaped like an abbreviated letter.

Reference numeral 8 denotes an insertion hole formed in a vertical side of the holder 7, and a recessed portion 9 is provided around the insertion hole 8.

10 is a slit provided on the horizontal side of the holder 7;
A locking bracket 11 fixed to the vehicle body is provided in the slit 10.
One end of the is adapted to be fitted.

In this embodiment, in order to ensure the fitting between the bracket 11 and the slit 10 of the holder 7, a sawtooth-shaped retainer 11a is formed at the fitting portion of the bracket 11.

Furthermore, reinforcing side walls 12 and 13 are integrally formed on both sides of the holder 7.

14 is a washer in which a cylindrical portion 15 is integrally formed;
The washer 14 is provided with a hole 16 that communicates with the cylindrical portion 15 .

The cylindrical portion 15 is fitted into the insertion hole 8 of the holder 7, and the main body portion of the washer 14 is fitted into the recessed portion 9.

In addition, the bolt 6 fixed to the housing 1 of the horn 1 is inserted into the cylindrical part 15 of the washer 14 attached to the holder 7, and the nut 17 is screwed onto the bolt 6. An alarm horn 1 is installed on the

As is clear from the above description, the holder of the present invention is made of an elastic and insulating material such as rubber and has a slit, so that it can be easily attached to a locking bracket fixed to the vehicle body. Moreover, since the horn is electrically insulated from the vehicle body by the holder, there is no problem of the terminal being damaged by electrolytic corrosion.

In addition, since a washer with a cylindrical part is interposed between the attachment part of the horn and the holder, the insertion hole of the holder will not be unevenly deformed by tightening the nut, and the horn will sound The attachment part between the container and the holder has excellent durability.
