[Embodiment of device]

 1 to 5 are external views of a pneumatic horn according to the present invention, FIG. 1 is a side view, FIG. 2 is a plan view, FIG. 3 is a side view seen from the side opposite to FIG. 1, and FIG. 1 is a back view as seen from the right side of FIG. 1 (threads of the air conduit are omitted), and FIG. 5 is a view as seen from the front of the trumpet.

In the pneumatic horn according to the present invention, the body portion 1 comprises a body 2 and screwed lids 3 and 4 provided above and below the body 2, and a connecting plate 7 is provided in front of the body portion 1 by a connecting plate 7. An integrally formed trumpet 5.6 is mounted, and a solenoid valve 8 having a socket 9 below and an air conduit 10 fixed integrally with the solenoid valve 8 are laterally mounted. Reference numeral 11 indicates a mounting plate for mounting the horn with the metal 11a on the vehicle body. The air conduit 10 is connected to an air supply source (not shown).

The main body 1, the body 2, the lid 3 and 4, the trumpet 5.6, the connecting plate 7 and the mounting plate 11 (excluding bearing metal) are all made of synthetic resin, but the solenoid valve 8 and the air The conduit 10 is made of metal.

Next, FIGS. 6 to 8 are views showing the inside of the main body 1, the trumpet 5.6, the solenoid valve 8 and the air guide tube 11. FIG. 6 is a sectional view taken along line AA of FIG. 7 is a horizontal sectional view of FIG. 3, and FIG. 8 is a BB sectional view of FIG. 7. . The solenoid valve 8 is provided with a solenoid 8a and a valve 8b. In the body 2 of the body portion 1, an air passage 2a communicating from the air passage 10a of the air conduit 10 through an air passage 8c opened and closed by the solenoid valve 8 and an air passage 2b branched from the air passage 2a. And 2c are provided, and the air passages 2b and 2c communicate with relatively large air passages 2d and 2e, respectively. The air passages 2b and 2d and the air passages 2c and 2e are opened and closed by diaphragms 3a and 4a, respectively. The diaphragms 3a and 4a are mounted with their outer peripheries on the annular walls 2f and 2g at the upper and lower ends of the body 2, respectively. It is pressed onto a circular opening.

The air passages 2d and 2e bend forward and end at the enlarged ends, respectively. Some of these enlarged ends communicate with each other. At the enlarged ends of the air passages 2d and 2e, ends 5a and 6a of the trumpets 5 and 6 which are integrated via packing are inserted. The ends 5a and 5b are fixed to the body 2 with screws S. The connecting plate 7 of the trumpet 5.6 is inserted into the communicating portion and fixed to the body 2 with screws. When the trumpet 5.6 is inserted, the air passages 2d and 2e communicate with the internal passages 5b and 6b of the trumpet 5.6, respectively.

The end portion 10 a of the air conduit 10 is curved inward so as to correspond to the portion 2 f of the body 2. Therefore, the end 10a of the air conduit 10 can be attached to the protruding portion 2h of the body 2 by fixing the air conduit 10 to the solenoid valve 8 with the claw 8c and then sliding them in the axial direction thereof. If the body is provided with pin-shaped projections, the air conduit 10 can be easily fixed to the body 2 by being heated and deformed after being inserted into the corresponding hole provided in the air conduit.

When using the pneumatic horn according to the present invention, when the solenoid 8a of the solenoid valve 8 is energized, the valve 8b is opened, air enters the passage 8a from the air passage 10a of the air conduit 10, and then the body 2 The air passage 2a is divided into two air passages 2b and 2c, the diaphragms 3a and 4a are pushed up to flow into the air passages 2d and 2e, respectively, and finally discharged from the inner passages 5b and 6b of the trumpet 5.6. And generate an alarm sound.

[Effect of device]

 According to the present invention, a pair of trumpets integrally formed through a connecting plate are slidably mounted on the front surface of the main body where the diaphragm device is integrally formed on both sides of the body, so that the number of parts is small and the assembly is easy. This makes it possible to obtain a device that is structurally strong and has an excellent appearance.

Further, a pair of air passages is provided in the main body, a diaphragm is placed across the air passages at the upper and lower ends of the main body, and the diaphragm is opened and closed with respect to the main body by a screwed lid. Since it is fixed, it is easy to install or replace the diaphragm.

Further, since the solenoid valve and the air conduit are slidably mounted on the side surface of the main body, the solenoid valve and the air conduit can be easily attached.
