Definitions

• the invention relates to a flashlight with rechargeable batteries and contacts on the housing outer shell over which a closed circuit with a battery charger can be produced, which is provided with an adapter plug for connection to a car or truck socket, in particular a cigarette lighter socket.
• Portable flashlights are usually rarely needed, but are in exceptional cases an indispensable tool, such.
• an indispensable tool such as in the home in a power failure, on unlit trails, to illuminate bell labels, house numbers or the like or in the event of a breakdown to illuminate the engine compartment or the like.
• Light-emitting diodes require much less power for operation, so that the total illumination time per battery set is correspondingly greater.
• light-emitting diodes in contrast to incandescent bulbs, are relatively impact-resistant and shock-resistant, so that their service life has also been extended many times over.
• light-emitting diodes are smaller than light bulbs, so that in conjunction with the lower power requirements, a significant miniaturization of the lamp could be achieved. This even went so far that small lamps had a diameter smaller than 1 cm, the length of the lamps being 5 cm or less. Such lamps can be carried as a keychain, so that these lamps are available if necessary. Further potential savings in flashlights result from the use of rechargeable batteries, which are more expensive to buy than disposable batteries, but are rechargeable multiple times.
• DE 732 364 describes a charging device together with a flashlight with built-in accumulator, which is suitable for the mains connection.
• the lamp head and the outward led charging contacts of the rod-shaped flashlight are so inserted into a cup-shaped receptacle of the charger that they can be anchored bayonet-like in a certain position, with a contact closure between the contacts of the charger and the flashlight is brought about.
• US 3,749,905 describes a charger for the batteries of a flashlight, which has a line connection, at the end of a plug is provided, which is inserted into the receiving socket of a car cigarette lighter.
• the housing of the charger has contact receptacles, which are connectable to corresponding contacts of the flashlight on the outer housing to close the circuit for recharging the batteries.
• the disadvantage of this device is that the charger must either be attached to a console in the car, so that it disturbs visually as well as outside the charging time.
• the charger can be stored in the footwell or on the passenger seat, however, such moving parts are undesirable due to the increased risk of accidents during sharp braking or fast cornering.
• DE 36 36 968 C2 describes a rechargeable flashlight, which consists of an accumulator and a double charging circuit containing central part, having at one end a power plug assembly and at the opposite end an adapter plug suitable for car sockets, in particular cigarette lighter connections. Further, this flashlight has a detachable with the central part, the adapter plug cross-reflector part and a power plug assembly covering the plug cap, wherein in the central part is provided on charging the battery via the power plug assembly effective means for separating the accessible contacts of the adapter plug.
• a switch actuated via a plunger switch should be provided to ensure that this already at the beginning of the removal of the accessible contacts covering the cap or the reflector part opened and thereby the electrical connection between these contacts and the mains voltage is interrupted.
• this arrangement has the disadvantage of being very bulky.
• the battery charger is a pot-shaped or sleeve-shaped housing into which the flashlight is inserted so that contacts on the inner part of the housing abut the contacts of the housing outer wall of the flashlight.
• the flashlight housing is substantially cylindrical and protrudes in the inserted position of the sleeve-shaped housing of the battery charger only partially.
• the battery charger can remain permanently in the cigarette lighter, where it does not bother because of its sleeve-shaped design, not even if the rod-shaped flashlight is plugged into this charger.
• the Stabtaschenlampe can remain permanently in the charger and thus in the cigarette lighter.
• the lamp is always tangible and in this way always charged.
• the cigarette lighter of a car is often no longer used, either because smoking while driving is considered disturbing and dangerous traffic or because large parts of the population are among the non-smokers.
• the cigarette lighter is usually located in easily accessible places in the car, so that there stored in the charger flashlight is always within reach, about to illuminate a dark way, doorbell signs, the engine compartment, etc. after disembarking. After use, the flashlight can be reinserted into the sleeve-shaped charger receptacle.
• a flashlight according to the invention shows the schematically illustrated embodiment.
• FIG. 1 It shows a flashlight 1 with a cylindrical housing 4, which is inserted into the pot-shaped housing 6 of a battery charger 2.
• contacts 3 are arranged, which are brought into the pot-shaped housing 6 of the battery charger 2 in contact with the contacts 7 when plugging the flashlight 1, which are arranged on the inside of the cup-shaped housing 6.
• the interior of the cup-shaped housing 6 is adapted to the size and shape of the housing cylinder 4 of the flashlight 1 such that a frictional connection prevents the flashlight 1 from slipping out.
• the pot-shaped housing 6 of the battery charger 2 in turn is plugged into the cigarette lighter socket 8 (dashed line) of a motor vehicle, wherein the outer contacts 5, 5 'of the battery charger 2 engage in corresponding receptacles of the cigarette lighter receptacle 8.
• the battery charger 2 not only assumes the function of an adapter by means of which a flashlight 1 with a relatively small housing diameter in a larger diameter receiving socket 8 of a cigarette lighter plugged, but ensured by an integrated transformer (not shown) also that the voltage applied in the cigarette lighter receptacle 8 voltage is converted into a corresponding charging voltage for the accumulators (not shown). Once the maximum charge capacity of the accumulators has been reached, the battery charger 2 switches off automatically, so that it is harmless for the flashlight 1 to remain plugged in the cigarette lighter for a longer period of time. Since the housing cylinder 4 of the flashlight 1 at least up to half or - depending on the size of the flashlight - beyond in the cup-shaped housing 6 is inserted, there is no hindrance from her. The front housing portion of the flashlight 1 is just so far that the flashlight is easy to reach, if necessary, to be quickly at hand.
