Abstract

This device comprises a base 2 which is fixed to a support 10 fixed to a vehicle and which carries an electrical connector; an at least partially transparent body 3, mounted on the base 2 and delimiting with it a closed enclosure; a light signal generating device housed in said enclosure and supplied through the connector. The base 2 is made of an elastic material and has an integrated foot 5 for fixing to the vehicle, which allows the base and the body to move with a limited amplitude relative to the support 10, deviating from the normal position. or working, and spring back to that position.

Description

The present invention relates to a light signaling device

of danger, especially intended

  to be used on slow vehicles.

  The invention more specifically relates to an app-

  similar to light signaling of the type which includes:

  a base intended to be fixed to a support

  ted by a vehicle, said base carrying a connector

  electric for connection to the power supply

  that of the vehicle; a partially transparent body; mounted on said base and defining therewith a closed enclosure; and an electrical signal generator

  luminous, housed in said enclosure and supplied with electric

  only, in use, through the connector worn

from the bottom up.

  The luminous signaling devices of

  ger of this type are used mainly, according to recent national and European regulations, on vehicles defined as "slow", according to the code of

  road, for example, towing machinery (self-propelled cranes

  trices, snow plows), agricultural machinery etc. These devices

  signaling reils may include genera

  electric light signal light type

  flashing or of the rotating light beam type.

  The luminous signaling devices of

  ger of the type defined above are intended to be mounted

  in a clearly visible position (for example on the cabi-

  the driver of the vehicle), and therefore exposed

  to the shock of obstacles, for example, to the shock on the branches

trees.

  To remedy this drawback, it has already been

  proposed to mount light signaling devices

  neuse in question in metal protective cages

  ques. Unfortunately, this solution is not complete-

  satisfactory, due to the increased difficulty of access to replace the lamp,

  the inevitable reduction of the signal strength

  and the fact that the shock against obstacles "robus-

  tes "is in any case likely to distort the

  metallic age and consequently damage the device

signaling.

  The object of the invention is to provide an apparatus

  danger signal light so that it is less likely to be damaged by the effect

of a shock against an obstacle.

  This object is achieved according to the invention by means

  a light signaling device of the special type

  above, the main characteristic of which is that the said base is made of a material

  elastic and has an integrated foot for fixing to the

  which is capable of allowing, in use,

  limited placement of base and body relative to

  support, deviating from a normal or tra-

  vail, and their elastic return to this position.

  Thanks to this characteristic, in the event of an impact

  against an obstacle, the luminous signaling device

  according to the invention flexes elastically to return

  then to the normal working position as soon as the

key is crossed.

  According to another characteristic, in their en-

  seems, the body of the light signaling device

  se and the base substantially form a sphere on which

  the foot protrudes downward.

  The at least partially transparent body of the signaling device is preferably made of a

  unbreakable material, for example, polycarbonate.

  Other features and advantages of the

  vention will be better understood on reading the description

  tion which will follow, of an exemplary embodiment and with reference to the accompanying drawings in which,

  Figure 1 is a perspective view of the ap-

  similar signaling according to the invention Figure 2 is an axial sectional view, on an enlarged scale, of the signaling device according to Figure 1; and Figure 3 is a partial view, partly in

  section, of a mounting foot for the signaling device

sation according to the invention.

  In Figure 1, we indicated as a whole

  in 1, a danger light signaling device

  lon the invention. This signaling device includes

  a base 2, which has substantially the shape of a go-

  det and is surmounted by a body 3 at least partially transparent. The base 2 is made of an elastomeric material, in particular rubber, and it is preferably provided in the region adjacent to its upper edge, with an annular metal reinforcing core 4 (FIG. 2). The body 3 is made of an unbreakable material, preferably a polycarbonate, and it has in its

  lower region an annular edge 3a, external threaded

  which mates with a corresponding thread

  in base 2. Alternatively, the body could be as-

  looked at base 2 by a snap-type coupling

query.

  The base 2 has in its lower part an almost tubular foot 5 come in one piece. In the

  embodiment shown in Figure 2, this foot presents

  substantially the shape of a bellows while, in

  the embodiment shown in FIG. 3, this foot pre-

  feels a thickened wall in which are embedded

  longitudinal reinforcing strips 6 of metal material-

lique.

  As is particularly apparent from the fi-

  gure 2, the foot 5 has in its lower part a

  pair of coaxial circular lips 7 and 8 between the

  which is inserted a metallic tubular element 9. A

  the inside of the lip 8 of the foot 5 is fixed a connector

  bipolar electric tor 30, of a type known per se, for example, of the type according to standard ISO 4148-1978 (F), form A. The tubular element 9 is intended to be threaded on a support (indicated at 10 in Figure 1), attached to a motor vehicle, in a manner known per se. To ensure stable mounting of the base on the support 10 around the lower end of the tubular element

  9, a clamp 11 is advantageously mounted.

  Inside the base 2 is anchored a plate

  that in shape 12 which plays the role of support for a dis-

  positive generator of light signals which, in the:

  reading shown in Figure 2, is of the type which

  comprises a fixed lamp 13 with which is associated a lamp

  rotating flector 14 rotated in one way

  known in itself by a geared motor unit 15. This latter

  deny is supported by plate 12 and has a shaft

  worm control unit 16 coupled to a toothing ex-

  the hub 17 of the reflector.

  The geared motor group 15 comprises an electric motor which is connected to the connector 30 (FIG. 2) at

  through conductors 18. In use, the mo-

  reducer 15 can be supplied through this connector

  by the electrical installation of the vehicle on the

  which the danger light signaling device

has climbed.

  As a whole, the body 3 and the base 2 form

  substantially lie a sphere on which the foot 5 projects downward. As well by the characteristics of the matter which composes it as by its conformation, this

  foot is capable of allowing in use at the

  and to the body 3 which overcomes it to describe displacements-

  limited deviations from a normal position or

  work in the event of an impact and then

  resiliently return to the normal position after the disappearance

  rition of the deforming force. Thanks to this characteristic

  tick, and in its partially spherical shape, the light signaling device according to the invention is unlikely to be damaged under the effect of shock against obsta

  keys such as tree branches.

  Of course, various modifications may be made by those skilled in the art to the device which

  has just been described only by way of non-binding example

  mitative without departing from the scope of the invention.
