Definitions

  • the invention relates to the field of portable lighting devices, also called portable lamps, used for temporarily lighting an area devoid of light.
  • the traditional portable lamp composed of a socket holder handle and a cage surrounding the bulb placed in the socket, is fixed by suspension by means of a hook with which the cage is fitted. If this method of attachment is suitable for work in a workshop with projecting elements, it cannot be used when there are no projections and for example to fix the light source inside a vehicle or on the body of this vehicle.
  • Patent US-A-4 238 816 describes a portable lamp which overcomes these drawbacks by using a suction cup as a means of fixing the base and by orienting the departure of the flexible fuse substantially radially.
  • suction cup Another disadvantage of fixing by suction cup comes from its ability to dissociate from the support after a more or less long time, which can bring the light source or the hood which protects it and which is generally hot to the touch, with walls such as synthetic coating of the dashboard or seat cover, which may melt or ignite in the event of prolonged contact.
  • the object of the present invention is to remedy these drawbacks.
  • the body of the base is made of a semi-rigid synthetic material, and has an elastically deformable peripheral skirt and capable of marrying a concave or convex bearing surface while in pressing the edge of the diaphragm of the suction cup, by reaction to the axial traction exerted by the lever, this body being integral with a transverse housing which, receiving the means for supplying the light source and carrying its control switch, s 'extends radially beyond the membrane to support a safety contactor, open at rest and whose feeler is able to come into contact with the surface receiving the base to close the electrical circuit leading to the switch
  • the safety contactor probe loses contact with the support and opens the electrical circuit supplying the light source, that is to say automatically interrupts the supply of this source, thereby eliminating any risk of burns or fire starting.
  • This arrangement therefore makes it possible to use, in complete safety, a light source having a high calorific release, for example, of the halogen type.
  • the reference numeral 2 designates a light source disposed at the end of a hose 3, the other end of which is secured to a fixing base 4.
  • this base 4 is constituted by the support body 5 of a suction cup fixing device comprising a circular membrane 6, integral with a vertical axis 7 slidably mounted in a bearing 8 of the body 5.
  • a pin 9 passing right through the upper end of the axis 7 ensures the articulation of this axis with the two branches of a yoke 10a, formed at the end of a lever 10.
  • the faces 12a and 12b of the yoke 10a coming into contact with the bearing 8 are separated from the geometric axis of the pin 9 by different distances and a spring 13 interposed between the membrane 6 and the bottom of the body 5, constantly reminds one of these faces against the upper face of the bearing 8.
  • the support body 5 is composed of a bottom 5a and a circular skirt 5b bearing on the peripheral edge of the membrane 6, but it is obvious that it can have any other geometric shape.
  • this body is made of an elastically deformable semi-rigid synthetic material so that its skirt 5b can be deformed to conform to the curve, convex or concave of the support, whether it is a glazing or a panel filling.
  • the body 5 is integral with a housing 14 which, arranged transversely, is parallel to the diametral plane coinciding with the median plane of the lever 10.
  • a housing 14 which, arranged transversely, is parallel to the diametral plane coinciding with the median plane of the lever 10.
  • One of the ends of this housing, and for example that 15 in FIG. 4, serves to the fixing of the flexible 3.
  • the bearing is crossed by a bore 16 serving for the passage of a hollow fixing rod 17, integral with the flexible 3.
  • the free end of this rod enters a well 18 juxtaposed with the bearing 15 and formed in the housing 14. This well is used for the installation of a nut 21 for fixing and for the passage of the supply circuit 19 of the light source 2.
  • the power cord 20 provided at its free end with the network connection plug, not shown, enters the housing 14 through the end of this box which is opposite to that linked to the flexible 3.
  • the insulated conductors 22 of the cord are connected to the switch 23, itself connected to the supply circuit 19.
  • the connection between the cord 20 and the conductors 22 is ensured by means of a safety contactor 24, disposed in the housing 14, and provided with a probe 24a projecting downward, beyond the membrane 6 , from which it is radially spaced.
  • the contactor 24 opens the electrical circuit and prevents any supply of the light source 2.
  • the recoil of the probe 24a in its closed housing the circuit and allows this supply. This arrangement therefore avoids any supply of the device, when it is not placed on a surface and therefore interrupts this supply in case of fall of the device by detachment of the suction cup.
  • Figure 1 shows that this device can be fixed on any smooth surface and, for example on the internal face of the front glazing of a vehicle to illuminate a work area on the dashboard of this vehicle. Thanks to the elastically deformable skirt 5b which, for common curves, is deformed by bearing on the membrane by a substantially circular bearing, the seal between the outside and the internal part of the suction cup is improved and the duration of fixing is increased.
  • the deformability of the base is increased by producing in its body 5 radial slots 26, angularly spaced from one another. These slots extend from the skirt 5b to the bottom 5a of the base. As shown, these slots may not open out of the skirt, or on the contrary open out of the latter, to increase the deformability of the base and allow it to marry more curved, concave or convex surfaces.
  • the device according to the invention is simple and inexpensive to produce, can be fixed to any smooth surface, magnetic or not, flat, concave or convex, inside or outside the vehicle , but also on any other surface adjacent to an area requiring repair and maintenance.
  • the suction cup fixing does not cause any deterioration of the surface against which it is affixed, which makes it possible to fix the device, even on fragile surfaces or whose repair is expensive.
  • the invention is not limited to the embodiment of the device which has been described above, both with regard to the shape of the suction cup, the number of suction cups used, the nature of the light source. and the means ensuring its supply, these means being able to be not only the network, but also the 12-volt electric circuit of the vehicle, and even even a battery integrated into the device.
