Definitions

  • the invention relates to a lantern powered by an electric battery comprising a housing with two superposed compartments separated by a plate which carries on its upper face a bulb and on its lower face a central connection and an eccentric connection connected respectively to the socket and base of the bulb, the battery being mounted in the lower compartment in a rotatable manner around the vertical axis of the lantern, so that the eccentric connection is in contact with one of the terminals of the battery in a rotary position and does not in another.
  • Such a lantern is known, for example from document GB-A-1216139. It has a closed box, with two superimposed compartments, the upper compartment containing a bulb and the lower compartment an electric battery.
  • the two compartments of the housing are coaxial and movable in rotation with respect to each other and the bulb can be turned on or off by relative movement of the two compartments of the housing.
  • the object of the present invention is to produce a lantern comprising switch means which are more difficult to detect by an uninitiated person.
  • a lantern as specified above, which is characterized in that the battery is provided with an insulating plate which carries said terminals and which comprises at least one ear projecting laterally relative to to the stack, the internal face of the lower compartment comprising at least one vertical longitudinal groove extended at its upper part, by means of a boss, by a portion of horizontal plane, so that each ear cooperates with one of said vertical grooves for a first guide of the stack along the vertical axis for the introduction of the stack into the housing and, after passing over the boss, is supported by its underside on said plane portion for a second guide of the battery during its rotational movement around said axis, up to a stop corresponding to the contacting of said terminals and of said connections.
  • the invention therefore makes use of a technique for fixing the battery in the housing, which can be called a “bayonet fixing” and which is in itself known in the field of lanterns, for example from document DE-C- 512 589.
  • a technique for fixing the battery in the housing which can be called a “bayonet fixing” and which is in itself known in the field of lanterns, for example from document DE-C- 512 589.
  • This is a simple mechanical fixing, the electrical switching of the bulb being ensured by other means.
  • This document therefore gives no instruction for switching the bulb by means not visible from the outside.
  • the edge of said ear can be indented and slide on a longitudinal rib internal to the housing and parallel to said axis.
  • the second guidance is carried out by rotation of the stack around the axis, the underside of the ear coming to rest on a portion of plane orthogonal to the axis, and the springs being in a state of low compression.
  • the ear can slide on the plane portion up to a stop corresponding to the contacting of said bulb connections and of the two battery terminals.
  • the bulb is turned off and the battery is removed from the housing by reverse operations.
  • the lantern according to the invention preferably comprises a unitary housing which does not reveal any switching means. Only an initiated person will guide the stack as specified above.
  • the unitary housing of the lantern according to the invention and its internal guide means can easily be made of plastic by extrusion blow molding. This results in significant manufacturing savings.
  • the lantern appearing in FIG. 1 comprises a plastic casing 1, having a general shape of revolution around a vertical axis 2, and open at its lower end 3.
  • This casing is divided by an intermediate plate 6 into two compartments 4 and 5 superimposed.
  • the upper compartment 4 contains an electric bulb 7 fixed on the upper face of the plate 6.
  • the lower compartment 5 contains a battery or a battery of batteries 8 having on its upper face an insulating plate 9 carrying two terminals 10 and 11. These two terminals are constituted by springs, one of which, the spring 10, is located in the center of plate 9 and on axis 2.
  • the terminals 10 and 11 are intended to be brought into contact respectively with electrical connections 14 and 15 carried by the lower face 13 of the plate 6 and connected respectively in a known manner to the socket. and on the base of the bulb 7.
  • the plate 9 of the stack 8 comprises two ears 16 and 17 diametrically opposite.
  • the ear 16 has a notch 18 for guidance and indexing capable of sliding on a rib, re 19 of the internal face of the compartment 5, this rib being longitudinal and parallel to the axis 2.
  • the ear 17 can, as to it, slide in a groove 20 of the internal face of the compartment 5, also longitudinal groove and parallel to the axis 2.
  • the internal face of the compartment 5 further comprises a boss 21 located at a level higher than that of the end face 22 of the rib 19, a first portion of plane 23 orthogonal to the axis 2, located at a level lower than that of the boss 21, and a second portion of plane 24 symmetrical of the first portion 23 relative to the axis 2 ; finally it has two rib-shaped stops 25 and 26.
  • the extraction of the stack then requires compression of the springs 10 and 11 to allow the passage of the ear 16 above the boss 21, then a longitudinal guidance along the rib 19.
