Description

The present invention relates to a support

  placing on a motor vehicle a device

  a luminous signaling system of a type known per se and which comprises an at least partially transparent body in which is housed a signal generator;

  light sources of the intermittent light type or

rotating light.

  These luminous warning devices are used, among other things, on slow vehicles, such as, for example, agricultural machinery, earth-moving machinery, cranes,

snowplow vehicles, etc.

  The object of the present invention is to provide

  a support which makes it possible to avoid deterioration

  positive light signaling that is plugged into it in

  the case of accidental shock of this device against an object

  stacle such as, for example, a tree limb, a

seigne, etc.

  According to the invention, this object is achieved by a support characterized in that it comprises: - an upper terminal portion of rigid material to which the luminous signaling device is fixed in use; - a lower end portion, also made of

  rigid, intended to be fixed rigidly to the vehicle

  tomobile, and - an intermediate portion fixed firmly between the two rigid end portions and made of a material

  in such a way as to allow the said portion

  superior - and to the signaling device

  is connected to this portion in use - of oscil-

  ler relative to the lower end portion.

  According to another characteristic, the tertiary portion

  superior mineral has an axial aperture

  in which are housed electrical terminals des-

  designed to allow the feeding of the signaling device

  lighting. Of said intermediate portion of the support, upwards two elastic branches

  extending along the upper terminal portion of the

  re and whose upper ends are connected to a crosspiece on which projects downwardly a cap-shaped body adapted to seal the mouth of said aperture of the portion portion

  upper terminal of the support. These elastic branches

  the crossbeam and the plug-shaped body are

  advantageously made in one piece with the por-

  elastically flexible intermediate support.

  There is currently a large

  equipped with one or more signaling devices

  rigid rods which are mounted on also rigid supports, which are attached to the vehicle, for example by welding. In the case of these vehicles, the replacement of the rigid signaling device

  by a flexible rod device, or the removal of the

  rigid port of the motor vehicle and its replacement by a flexible type of support involve a certain expense. Another object of the present invention is therefore

  to propose a solution that makes it possible to

  flexible installation of a signaling device

  on a rigid support without requiring replacement

  signaling device or support.

  According to the invention, this object is achieved by a

  support device that can be used as a prolongation

  characterized in that it comprises in combination

  sound: - an upper connector, of a type known per se, suitable

  to mechanically and electrically couple to the

  luminous signage; - A lower connector, also of a type known per se, adapted to mate mechanically and electrically to a support rigidly fixed to the motor vehicle; and - an intermediate portion, firmly attached to said

  connectors and made at least partly of a material

  resilient, so as to allow in use

  signaling device connected to the

  to oscillate relative to the support, and consequently

  compared to the motor vehicle.

  Other features and advantages of the

  will be better understood when reading the description of

  following example of an embodiment and with reference to the accompanying drawings in which:

  FIG. 1 is a perspective view of a sup-

  port according to the invention and a signaling device

luminous association associated with it;

  FIG. 2 is a perspective view, on a scale

  the enlarged, a support according to the invention;

  FIG. 3 is a side view, on an even scale,

  enlarged, the support according to the invention, partly in section III-III of Figure 2; and

  FIG. 4 represents a device according to the invention.

  which can be used as an extension between a rigid rod light

  a rigid support firmly attached to a vehicle.

  As can be seen by referring to the figures

  1 to 3, a support according to the invention has a

  I usually lie down, with two end portions

  1 and 2, respectively upper and lower, in

  rigid material, in particular of metallic material.

  In the example of realization represented, the

  your end portions have a tubular shape and are

  linked by an intermediate portion 3, which is also

  laire, made of an elastomeric material.

  In FIG. 2, the end portions 1 and 2 have been drawn entirely in solid lines, as if the intermediate portion 3 were transparent, for

  better illustrate the characteristics of these ter-

  minales. As is apparent from FIGS. 2 and 3, the end portions 1 and 2 present, close to

  their lower end edge for one and

  superior for the other, a plurality of annular projections

  outside nines la and 2a, in the intervals between

  which are provided with internal wall openings

  denoted by lb and 2b respectively.

  As can be seen in particular in FIG. 3, the intermediate portion 3 is made by molding

  in an elastomeric material so that its ends

  mites encompass externally and internally the ex-

  corresponding trenches of the rigid end portions 1 and 2 and that, in particular, they cover their outer annular projections la and 2a. During molding, it is formed through the openings of the walls

  1b and 2b small bridges of elastomeric material which

  run to anchor the middle portion

  3 on the end portions 1 and 2.

  The upper end portion 1 has a

  internal thread into which an element 4 is screwed (

  2 and 3) substantially bucket-shaped, externally threaded

  térieurement. The bottom wall of this shaped element

  bucket, designated 5 in FIG.

  6 (only one of which is visible on the

  3) to enable the supply of electricity

  cited and the control of a signaling device

  which is generally indicated by 10 in FIG. 1, which is firmly coupled to the support

in a known way.

  In the embodiment shown, the

  lower end portion 2 of the present support

  a thread for the purpose of

  this support to a motor vehicle. The end portion 2 of the support could also be fixed to the vehicle in other ways, for example by

welding, etc.

  In use, the elastic intermediate portion

  flexible support allows the final portion to

  the upper 1 and the signaling device 10 which

  it is fixed to oscillate to a certain extent with

  port at the lower terminal portion 2 and consequently

  compared to the vehicle. This therefore makes it possible to prevent the deterioration of the luminous signaling device in the event of an accidental impact against an obstacle such as

branches, signs, etc.

  According to an advantageous embodiment, there are provided two elastic branches 7 and 8 which start from the intermediate portion 3 of the support upwards, which extend along the upper end portion 1

  and whose ends are connected at the top by a

  verse 9 on which an appendix

  11 having the shape of a plug and which is adapted to seal the mouth of the cup-shaped element 4 in which are housed the electrical terminals 6

  as shown in FIGS. 2 and 3 -

  when, in use, the light-signaling device 10 is disconnected from the support, for example to

  to be able to carry out maintenance operations on the

  signaling system. The closure of the

  mating the support with plug-shaped appendix 11 prevents the electrical terminals 6 from being short-circuited by an accumulation of water

  rain in the bucket element 4 which carries these contacts.

  The side branches 7 and 8, the cross member 9 and the corresponding appendage 11 in the form of a plug are made by molding, in one piece with the portion

intermediate 3 of the support.

  In FIG. 4, a support is indicated in 20

  rigid type of traditional, fixed to the flag 22 of a

  automobile hicle for example by welding 24.

  In the holder 20 is incorporated in a way

  known a female type electrical connector.

  In 10, a signaling device has been indicated

  a traditional type of light

  rigid 12 inside which is arranged a

electrical connector of the male type.

  As a whole, 30 has been designated

  elastically flexible sitive according to the invention. This provision

  device comprises an upper connector 32, of a type con-

  naked, able to mate mechanically and electrically

  the light signaling device 10, and a lower connector 34, also of a type known in

  which is likely to mate mechanically and electrically

only to the support 20.

  The connectors 32 and 34 are advantageously, although not necessarily, of the type conforming to the standard

ISO-A-4148 (1978).

  In 36, an intermediate portion has been indicated

  of the extension device 30 having a substantially

  tubular material and composed of an elastic material,

  particular of an elastomeric material. This portion

  intermediary is overmolded on the ends of the connectors

  32 and 34, which are advantageously provided with external projections capable of improving the anchoring of

  these connectors on said intermediate portion.

  The intermediate portion 36 of the device

  lengther 30 advantageously has a thickness of

  reinforced king in its central part. In particular, the diameter of the central part of this portion in

elastomer is enlarged.

  FIG. 4 shows at 11 a plug of an elastomeric material connected by elastic branches 7 and 8 to a ring 13, also made of elastomeric material, force-fitted on the connector 32. The plug 11 is in this case also able to seal the

  mouth of the upper connector 32 when, in use

  the light signaling device 10 is de-

  connected to the extender 30, for example to allow performing maintenance operations on this device

signaling.

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

  just described as a non-limiting example.
