Abstract

A lantern has at one end of its tubular body 10 a transparent or translucent cover enclosing a U-shaped fluorescent light tube 11 the two ends of which are received in contact sockets at said end of the body, so that the limbs of the tube extend in the same direction as the lengthwise dimension of the body. A light bulb 14 is mounted in a holder between the ends of the light tube and is connected into an electric circuit to produce an intermittent or blinking light. A sleeve 16 of red or amber transparent or translucent material can be slid axially between a position about the body and an operative position surrounding bulb 14. The body houses batteries for energising the tube 11, bulb 14 and the bulb 26 of the flashlight assembly and carries a suitable switch assembly for selectively lighting the tube and bulbs singly and in one or more combinations. <IMAGE>

Description

SPECIFICATION Improvements relating to lanterns This invention relates to lanterns and has a particularly useful but by no means exclusive application in battery-operated lanterns which are combined with flashlights and/or with intermittent (blinker) and/or spot (search) lights.
According to this invention there is provided a lantern comprising a body carrying in substantially side by side relation to each other two electrical connectors which are connected in circuit with current supply terminals of the lantern and to which are respectively connected the two ends of a fluorescent light tube and a transparent or translucent cover mounted on the body, and housing said tube. The end portions are preferably provided by parallel limbs of the tube and the tube may conveniently be U-shaped.
In one preferred construction the body of the lantern is straight and tubular and carries the two electrical connectors at one end thereof, the limbs of the tube extending in line with the body. The other end of the body may carry a holder for a light bulb, a concave reflector surrounding the light bulb and a transparent lens, which together form a flashlight.
According to a preferred feature of the invention a light bulb connected in circuit with an automatic blinker device for causing the bulb to light intermittently is disposed between the end portions of the tube. This light bulb may be encircled by a transparent or translucent coloured (e.g. red or amber) member having a diameter greater than that of said end portions of the tube. Alternatively, a transluacent or transparent coloured sleeve mey be mounted on and encircle part of the body and is selectively movable lengthwise of the body into a position in which it extends about the light bulb disposed between the end portions of the tube.
One embodiment of the invention will now be described, by way of example, with reference to the accompanying drawing showing a diagrammatic sectional view of a lantern according to the invention.
Referring to the drawing, the lantern comprises a body 10 having at one end a U-shaped fluorescent tube 11 and at the other end a flashlight arrangement 12. The body loins tubular and carries at said one end a mounting member 13 providing two spaced connector sockets for receiving the contactor pins at the respective ends of the two limbs of the tube 11. The mounting member also provides a connector socket for a light bulb 14 conveniently disposed between the limbs of the tube 11. A transparent or translucent cover 15 is detachably mounted on the mounting member in any convenient manner and encloses the fluorescent tube 15 and the light bulb 14.A coloured transparent or translucent sleeve 16, which is preferably amber or red, is axially slidably mounted on the body 10 and can be moved manually into the inoperative position in which it is shown in the drawing and into an operative position in which it is disposed about the cylindrical surface of the cover 15. The light bulb 14 is connected in circuit with a blinker device to provide an automatic intermittent light which, when the red or amber sleeve is in its operative position, a warning light.
The flashlight portion of the lantern comprises an electrically insulating platform member 19 having at one side electrical contacts 20, 21 for engagement with an electric power source, in the form of a plurality of separate cells 22 or a battery, and on its other side a socket 23 for receiving a light bulb 26, and electrical contacts 24, 25 for the bulb. The flashlight portion also comprises a reflector 27 with a central boss 28 which encircles the socket 23, a lens 29, and a lens holder 30 which is detachably secured on the adjacent end of the tubular body.
A switch mechanism (not shown) is provided which selectively enables energisation of 1) the flashlight bulb 26 alone, 2) the blinker bulb 14 alone, 3) the fluorescent tube 11 alone, 4) the fluorescent tube 11 and blinker bulb 14 together, and 5) the flashlight bulb 26 and blinker bulb 14together.
The use of a U-shaped fluorescent tube in this way enables the lantern to give 360 illumination about the lengthwise axis of the lantern and substantially 270 illumination in planes containing the said axis.
The disposition of the blinker bulb between the limbs of the tube 11 enables this space to be utilized to advantage as well as providing a large lens for its warning light.
A socket connection and appropriate circuitry may be provided in the known manner four the lantern to be powered by the battery of a motor car, e.g. via a cigarette lighter socket.
In an alternative construction, not illustrated, the blinker bulb 14 is surrounded by an axially elongate transparent or translucent red or amber cover which is of somewhat larger diameter than the U-shaped tube 11 so as to be visible even when the lantern is viewed in the plane of the U-shaped tube. In this construction the sleeve 16 may be omitted.
1. A lantern comprising a body carrying in sub stantiallyside by side relation to each other two electrical connectors which are connected in circuit with current supply terminals of the lantern and to which are respectively connected the two ends of a fluorescent light tube and a transparent ortranslu- cent cover mounted on the body and housing said tube.
2. A lantern as claimed in claim 1, wherein the end portions of the tube extend parallel to each other.
3. A lantern as claimed in claim 2, wherein the tube is U-shaped.
4. A lantern as claimed in claim 3, wherein the body of the lantern is straight and tubular and carries the two electrical connectors at one end thereof, the limbs of the tube extending in line with the body.
5. A lantern as claimed in claim 4, wherein the other end of the body carries a holder for a light bulb, a concave reflector surrounding the light bulb and a transparent lens, which together form a flashlight.
