Protection device for the horn on automobiles

In many types of cars, the horn for the delivery is acoustically located Signals under the fender where it's fouling through Foreign bodies and the ingress of water.

The present invention now relates to a protection device for the horn on automobiles, which is designed as a protective capsule covering the mouth of the horn, the protective capsule with the outlet the sound waves of the horn signal, which prevent the entry of foreign bodies, is provided.

The protective device can be made of metal, elastic plastic or Rubber.

In the drawing, for example, embodiments of the subject matter of the invention are shown shown, namely show:

Fig. 1 is a vertical section through the protective device of a first embodiment,

Fig. 2 is a front view of the same

3 shows a vertical section of a second embodiment

BATH ORIGINAL

4 is a view of a third embodiment of a protective device made of elastic plastic,

FIG. 5 shows an axial section through the protective device according to FIG. 4 clamped onto the horn,

6 shows a vertical section through a fourth embodiment a protective device made of elastic plastic and

FIG. 7 shows the protective device according to FIG. 6 in the direction of the arrow VII.

The protective device shown in FIGS. 1 and 2 forms a protective capsule 1 made of sheet metal that can be plugged or clamped onto the mouth of the home H and widening conically to the front and has an elastic fastening ring 2 at its rear end, for example lobed by incisions 2 ' , which protrudes over an inner ring 3 serving as a stop. The front of the protective capsule 1 is provided with a cover 4, which has a rectangular opening 5 in its central part for the passage of the acoustic signal generated by the horn H. This rectangular opening 5 is covered with horizontally extending lamellae 6 _f which are attached with their ends to the cover 4 and form obliquely downwardly protruding deflection surfaces, which prevent the entry of spray water and feces through the opening, but allow sound to escape. A drain hole in the lower part is designated by 7, through which any water that has entered the protective capsule can be drawn off.

The second exemplary embodiment according to FIG. 3 differs from the first in the steeper arrangement of the slats and the fact that their rear parts are drawn through the opening and in the interior the protective capsule 1 libgon. Furthermore, the shape of the protective capsule 1 different. The parts given reference numerals have the same meaning as stated above.

The protective device described is with its fastening tape 2 can be attached to the horn H, where the easily deformable tabs of the ring 2 can be brought into contact with the horn by inward bending,

The embodiments of the protective device shown in FIG. 4 to 7 are in contrast to those made of sheet metal _ Embodiments according to FIGS. 1 to 3 made of elastic plastic such as Elastic or rubber made. In this case, the fastening ring 2 of the protective capsule 1 does not have to be lobed.

According to FIG. 4, the protective capsule 1, which can be clamped onto the mouth of the horn H and widening conically towards the front, is provided with an elastically stretchable fastening ring 2 which has two spaced-apart inner rings 3, 3 ^f serving as a stop on the inside. When the protective capsule 1 is clamped onto horns with a larger mouth diameter, the first inner ring 3 is used as a stop for the mouth edge of the home H, as shown in FIG In the case of horns with a smaller mouth diameter, the second inner ring 3 »serves as a stop, as can be seen in FIG. When the device is clamped onto the horn H, the elastic fastening ring 2 is expanded in accordance with the external diameter of the horn, so that the device is securely seated on the horn under the effect of the tensile stress. *

In Fig. 5, a rectangular opening 5 on the cover 4 of the protective capsule 1 for the passage of the acoustic signal generated by the horn H is covered by a protective shield 6 ^f extending obliquely from top to bottom. The protective shield 6 ^f is equivalent to a single large lamella 6 according to FIGS. 1 to 3. This is connected with ä its upper edge and with its side wall portions 6 'with the lid 4 tightly. The protective shield 6 ^T allows the exit of the acoustic waves and at the same time prevents the entry of foreign bodies such as water spray or feces through the opening 5.

In the embodiment according to FIG. 6, the rec'- · - :. The baggy opening 5 in the cover 4 of the protective capsule 1 is covered by an outer protective shield B ¹ , which protrudes obliquely downwards and which is firmly connected with its upper edge and its side wall parts 6 ″ to the cover 4. This is provided with an inner shield 8, which is softer is firmly connected to the upper edge of the opening 5 of the lid 4 and obliquely downwards

in the interior of the capsule 1 protrudes. The inner shield 8 is only half as long as the cover shield 6 ', the protective shield 6' forms with it the inner shield provides a double safeguard against the ingress of foreign bodies, in particular droppings. The protective shield 6 'and the inner shield 8 expediently consist of one piece and run offset to one another in the vertical direction.
