Definitions

  • the present invention relates to a flat battery flashlight.
  • Such a lamp generally comprises a metal or plastic housing formed with a bottom and a cover associated along one of their long sides by a hinge and according to the other by a locking member.
  • the cover is provided with a parabolic reflector, the entrance of which is closed by a transparent pane and which is pierced in its center to allow passage to a bulb.
  • the bottom of the case contains the flat battery and an insulating plate carrying an electrical circuit; the latter comprises two conductive strips each maintained in contact with a terminal of the battery, a bulb whose stud is directly supported directly on one of the conductive strips, and a conductive tab forming a spring whose position is controlled by a switch applying this tab against the other blade, when it is in the ignition position.
  • the switch consists of a push button with two extreme positions (on or off); it slides in a light provided in the curved side edge of the bottom; it is located approximately at the height of the bulb, so that it can be reached by the thumb of the user holding the lamp.
  • the present invention aims to avoid this drawback.
  • the present invention relates to a flat battery flashlight comprising a plastic casing formed by a bottom and a cover provided with hinges and a locking member, said cover being provided with a parabolic reflector, the entrance is closed by a transparent pane and which is pierced in its center to allow passage to a bulb, said housing further containing a flat battery, two conductive blades respectively in permanent contact with the two terminals of the battery and means to connect them respectively to the stud and to the base of said bulb by means of a push button with two extreme ignition positions and extinction, characterized by the fact - That said cover carries said push-button at the level of a light presented by its edge, as well as said bulb via a metal collar secured to said reflector and in electrical contact with said base, but leaving free access to said pad , - that said conductive strips are fixed in said bottom, - that, when the housing is closed, one of said blades comes into contact with said stud, and the other in contact with said base if the push-button is in the ignition
  • said bulb is provided with an insulating bulb holder on which is folded down the edge of said base which comes into contact with a shoulder presented by the central chimney of said flange secured to said reflector.
  • said window has the form of a cup whose edge is turned towards the external face of said cover and which constitutes a housing for the folded edge of said reflector, said cup and said reflector being held against the external face of the cover of said housing by a plastic ring snapped into said cover.
  • said push button is provided with a second plastic tongue provided with ribs, cooperating with grooves presented for the edge of the light in the cover where it moves and which define said extreme ignition and ignition positions. extinction.
  • the flashlight visible in FIG. 1 comprises a housing formed by a cover 1 and a bottom 2 made of plastic, for example of the ABS type. They are secured by two polypropylene hinges 3 and 4 snapped into housings 5 and 6 of the cover 1 and housings 7 and 8 of the bottom 2.
  • a rib 9 located on the edge of the bottom 2 opposite to that which presents the housings 7 and 8 cooperates elastically with a groove in the cover 1, not visible in FIG. 1, and ensures the locking of the housing.
  • the bottom 2 is intended to contain a flat stack (not illustrated) and two conductive strips 11 and 12 fixed at the level of two slots 13 and 14 by plastic pins 15 and 16 secured to the bottom 2.
  • the ends 17 and 18 of the two strips 11 and 12 are in permanent contact respectively with the two terminals of the battery.
  • the end 19 of the blade 11 is intended to be in contact with the stud of the bulb, while the end 20 is intended to come into contact with the base.
  • the bottom 2 finally comprises two bars 21 and 22 on which the two clips 23, 24 are snapped elastically from a plastic clip 25 pierced with a hole.
  • the cover 1 has a first circular opening 26 for the optical system of the flashlight.
  • the latter comprises a bulb 30 with its stud 31 and its base 32 whose edge 39 is folded down.
  • the base 32 is housed in a bulb holder 33 made of insulating material so that its edge 39 comes to bear on the end 34 of this bulb holder.
  • Reference 35 is a metal flange having a conical intermediate part 37, a central cylindrical chimney 36 inside which is housed the bulb holder 33 so that the edge 39 of the base 32 comes to bear on a shoulder 40 of the collar 35.
  • the latter has an extreme annular portion 38.
  • the reflector 50 is provided with a tubular portion 51 which is fixed on the external wall of the chimney 36 of the flange 35.
  • the edge 52 of the reflector 50 is folded outwards.
  • a plastic window 53 in the form of a cup comes cover the reflector 50 with its edge 54.
  • the bulb holder 33, the bulb 30, the flange 35, the reflector 50 and the window 53 are nested one inside the other, and this assembly is held pressed against the external face of the cover 1 thanks to a plastic ring 55 provided with lugs 56 snapped into openings 57 of cover 1.
  • the push button 60 the external face of which is provided with a rib 62 making it easier to grip, comprises two insulating tongues parallel to one another 64 and 65. These two tongues snap in and slide in a slot 61 provided in the curved edge of the cover 1.
  • the lower tab 64 is used directly for switching off the bulb 30, while the upper tab 65 has a function of guiding the button- push-button thanks to its two orthogonal ribs 67 and 68 which cooperate with grooves provided in a part 63 of the cover 1. More precisely, a groove 71 comes to block the rib 68 for the ignition position (FIG. 2) while the groove 72 corresponds to the off position ( Figure 3).
  • the tongue 64 of the push button 60 in the ignition position does not act on the end 20 of the conductive strip 12; the blade 12 can therefore ensure contact between a terminal of the battery, the flange 35, and the edge 39 of the base 32 of the bulb 30.
  • the stud 31 is in permanent contact with the end 19 of the blade 11, it - even in contact with the other terminal of the battery.
  • the insulating tongue 64 of the push button 60 is in the extinguished position, because it separates the end 20 of the tongue 12 from the flange 35.
  • the electric circuit of the bulb is therefore open.
  • the flashlight according to the invention is much easier to hold in hand than the usual flat battery flashlights.
