Definitions

  • the present invention relates to the housings of electric pocket lamps powered by batteries.
  • US-A-1,404,077 provides a removable battery in the housing of an electric lamp.
  • the electric circuit battery-light bulb is closed or opened by actuating a push button outside the housing which allows the battery to be moved axially in order to put the battery pad in contact or out of contact with the base of the bulb.
  • this patent US-A-1,404,077 describes an electric pocket lamp housing comprising at its upper part a glass C 3 and a parabolic reflector C 2 carrying in its center a lamp C, the lower part of this housing comprising a cradle 11, 12 battery support, movable in vertical translation under the action of a push button 13, so as to bring the battery terminals into contact with the central contact pad C and the base C 'of the lamp by means of a metallic element 10, 11, 12.
  • a metallic element 10, 11, 12 is designed for cylindrical cells which have a terminal at each end.
  • the element 11, 12 for supporting the battery must also be used for the transmission of current from the rear pole of the battery to the base of the lamp, which requires a relatively complex element in four parts 10, 11, 1 1 a and 12.
  • Flashlights are also known such as those described in the patent application FR-A-2009032, which comprise a single piece intended for fixing the lighting head as well as for housing the bulb, said part being made of an electrically insulating material.
  • This patent application describes flashlights only intended for cylindrical cells and moreover comprising two metal plugs 7 and 9 and a switch device provided with a blade in contact with the pole of the cell opposite the stud of said cylindrical cell and coming into contact with one of the cards.
  • the flashlights according to the cited French patent have a complex assembly and are therefore expensive to manufacture.
  • the housing according to the invention makes it possible to avoid all the drawbacks exposed above by limiting to one the number of metal parts entering into its production, which part, possibly, can be easily replaced in the event of deterioration.
  • the present invention relates to an electric pocket lamp housing composed of an upper body and a lower plastic body assembled by clipping, the upper body comprising the glass and the parabolic reflector, itself bearing in its center a bushing holder ring, in which the lower body comprises a mobile battery support cradle in vertical translation under the action of a push button so as to bring the battery terminals into contact with the bushing and the base the lamp, characterized in that, the battery being rectangular, the battery support cradle is made of plastic, housing comprising a single metallic contact element, consisting of a blade connected to the socket, the cradle being composed of two sides inclined sides connecting a lower cross member, located under the middle part of the base of the pile, to an upper retaining plate covering a few millimeters the upper transverse edge of the stack we do not overwrite the terminals thereof, said support cradle being slidably mounted in the spacing of the side walls of the housing.
  • the housing consists of a lower body 1 and an upper body 2 which are assembled by clipping along a horizontal joint.
  • the upper body has in the upper part a hemispherical bulge in which is embedded a parabolic reflector 3 held in position by the positioning of the glass 4 in the recess formed by the edges of the hemispherical bulge, achieving by the elasticity of the material a crimping of the assembly.
  • the reflector 3 carries in its center a bore in which a forceful ring 5 made of plastic molded on a metal bush 6 is fitted by force, comprising, obtained by pushing back, threads in which the bulb 7 is screwed.
  • the socket 6 comprises a flexible metal blade 8 intended to make contact with a pole of the battery.
  • the lower body 1, of rectangular section comprises, in the upper part of one of its small faces, a groove 9 opening into the contiguous plane of the upper and lower bodies, in which the axis 10 moves in translation.
  • push button 11 controlling the alternating vertical movement of a cradle 12 supporting laterally and above and below the battery 13, so as to bring the terminals of the latter into contact or not with the metal blade 8 of the socket 6 and with the base of the bulb 7.
  • the lateral sides of the cradle are inclined to locate the lower cross member under the middle part of the stack, the upper retainer being limited to a few millimeters of overlap of the transverse edge of the stack so as not to interfere with one of the terminals thereof.
  • Immobilization of the pusher 11 in the "on” or “off” position is achieved by cutting the groove 9, which cut is made up of two intersecting circular orifices 9a and 9b, opening onto the joined plane of the upper and lower bodies by a parallel edge groove 9c.
  • the diameter of the orifices 9a and 9b on the one hand and the width of the groove 9c and of the constriction 9d created by the intersection of said orifices on the other hand correspond respectively, apart from the functional clearances, to the stepped diameters 10a and 1 Ob of axis 10 of the push button.
  • the height of these diameters to allow the translation of said push button is obtained by pressing along arrow F, causing a translation of the axis of the pusher in this direction, the comparison of the diameter 10b with the thickness of the housing being made possible by the elasticity of the wings of the push button whose curved ends are in permanent support on the external face of the case.
  • the vertical guide in translation of the push button is obtained by means of two ribs 14 laterally framing said push button.
  • the shouldered ring may comprise, executed in the material which constitutes it, the threads in which the bulb is screwed, the flexible metal blade 8 then being alone incorporated into the ring so that its end can come in contact with the socket after screwing it.
