1,210,641. Electric torches. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 2 Jan., 1969 [12 Nov., 1968], No. 236/69. Heading F4R. A flashlight for emergency use, comprising a bulb 12, a reflecting mirror 8, cells 11 and spring 5 in a case 4, is retained on a holding member 22 on a hanger 2 in such a way that the holding member breaks the electric circuit and puts the light off when the flashlight is on the hanger, the circuit being made and the light being on when the flashlight is removed from the hanger in use. The holding member 22 may be bifurcated and pass through a hole in .the flashlight casing to interpose itself between two adjacent cells 11 or between the bulb and its adjacent cell to break the circuit, the bifurcations passing on either side of the positive electrode terminal 16 of the cell to guide the holding member into position. In an alternative embodiment, Figs. 6A and 6B (not shown), internal projections are provided on the bifurcations to more securely retain them in position on either side of the terminals. A rotatable ring, Fig. 8A (not shown), may be fitted to close the hole in the easing during use. Various other configurations of plain and bifurcated holding members are described. Holding arms (23), Fig. 2 (not shown), clasp the body of the flashlight to prevent it being knocked accidentally out of position. The hanger may be screwed to a supporting structure, such as a wall, or it may be provided with an adhesive so that it can be stuck into position. In a further embodiment, Figs. 10A, IOB and 11 (not shown), the holding member fits into a groove at the end of the flashlight body opposite the bulb and lifts a looped or T-shaped member to pull the spring out of contact with the cells to break the circuit. |
