Abstract
The invention relates to a lantern whose housing (1) includes two superposed compartments (4, 5), the first of which (4) contains a light bulb (7) and the second of which (5) contains a single-cell or multi-cell battery (8), switching means being provided for switching the light bulb (7) on and off. In accordance with the invention, the housing (1) has a one-piece structure without a bottom, at least one portion of the casing of the battery co-operating with the inner surface of the second compartment (5) to guide the battery (8) when it is being inserted in the housing (1) and then to switch said light bulb (7) on and off. Application to lanterns on work sites.
Claims11
A battery-operated lantern comprising:
- a housing having
- a circumferential wall extending about a central axis,
- a support member positioned transversely to said axis and defining one end of a battery compartment inside the circumferential wall of said housing, the battery compartment having an open end opposite said support member,
- first guide means in the battery compartment extending parallel to the axis along the inside surface of the circumferential wall,
- second guide means in the battery compartment extending circumferentially around the inside surface of said wall, and
- a stop means on the inside surface of said wall and spaced circumferentially from the first guide means;
- a light bulb mounted on said support means on the opposite side thereof from the battery compartment;
- a pair of electrical contacts mounted in the battery compartment and conductively connected to the light bulb;
- an electric battery removably positioned in the battery compartment, said battery having a pair of terminals;
- and
- follower means associated with said battery for slidably engaging said first guide means for permitting said battery to be axially inserted into or withdrawn from the battery compartment at a first predetermined angular position, for slidably engaging the second guide means when the battery is inserted a predetermined distance into the battery compartment for permitting said battery to be rotated inside the said compartment between the first angular relation and a predetermined second angular relation at which the battery terminals conductively touch said electrical contacts, and for engaging said stop means when the battery is in said second angular position.
