Description

[Detailed description of the invention] This invention relates to the improvement of a portable light in which the battery is inserted and taken out from the front end opening of the main body case to which the lens cap is screwed. This relates to the mounting structure of the plate.

Conventionally, in this type of portable light, the base end of a battery receiving plate having a hinge part is fixed to the inner wall of the front end opening of the main body case with screws, etc., and the base end is fixed to the inner wall of the front end opening of the main body case, and the base end is fixed to the inner wall of the front end opening of the main body case, and the base end is fixed to the inner wall of the front end opening of the main body case, and the base end is fixed to the inner wall side of the front end opening of the main body case, and the base end is fixed to the inner wall side of the front end opening of the main body case. When a light bulb is attached and the lens cap is screwed onto the main body case, an electrical connection is made between the light bulb side and the battery side via the lead plate of the battery receiving plate pressed against the reflector side. It is configured as follows.

However, with the above configuration, the battery receiving plate must be fixed to the main body case 1 side with screws, etc., so the assembly work is troublesome, and when replacing the battery, the lens cap must be removed from the main body case. If you just remove it, the inside of the main body case will remain partitioned by the battery receiving plate, and it will be difficult to remove the battery unless you open the battery receiving plate towards the front, which makes it difficult to replace the battery. It's annoying.

Therefore, in this invention, a reflector is fixed to a lens cap that is screwed onto the open end of a main body case with an open front end, a battery and a battery receiving plate are arranged inside the main body case, and the battery receiving plate is A cylindrical portion for holding a light bulb is formed on the front surface, a lead plate is attached to the rear surface to conduct electricity between the light bulb and the battery, and a plurality of elastic protrusions are provided protrudingly surrounding the cylindrical portion concentrically. A cylindrical portion at the rear end of the reflector is fitted between the elastic protrusion and the cylindrical portion, and the fitting protrusion of the elastic protrusion is fitted into an annular groove formed on the outer periphery of the cylindrical portion. Then, the reflector is rotatably attached to the battery receiving plate, and in this attached state, the brim portion of the light bulb is connected to the cylindrical portion and the retaining flange formed on the reflector side cylindrical portion. A rotation prevention piece is provided protruding from the rear surface of the battery receiving plate to be secured to the inner wall side of the main body case, and the rotation prevention piece screws the lens cap into the open end of the main body case. By positioning the battery receiving plate until the battery in the main body case presses against the lead plate on the rear surface of the battery receiving plate, the battery receiving plate directly holds the light bulb, and If the battery receiving plate is rotatably attached to the cylindrical portion of the reflector held in the lens cap, and the lens cap is screwed onto the main body case, the battery receiving plate is set at a position where it will press the battery. To provide a portable electric lamp in which a battery receiving plate can be easily assembled, and batteries can be easily replaced.

Another object of this invention is that when the battery receiving plate is attached to the cylindrical portion of the reflector, an elastic protrusion is formed concentrically surrounding the bulb holding cylindrical portion on the front surface of the battery receiving plate, and this cylindrical portion By fitting and holding the cylindrical portion of the reflector between the elastic protrusion and the elastic protrusion, the battery receiving plate itself can be rotated directly with respect to the reflector while being elastically held, thereby preventing the light bulb from defocusing. Replacement can be done by simply attaching and detaching the battery receiving plate, and this prevents the battery receiving plate from wobbling, improving retention of the built-in battery and preventing poor contact between the lead plate on the battery receiving plate and the bulb. It is something that we try to do.

Furthermore, another object of this invention is that when attaching the battery receiving plate to the cylindrical part of the reflector, by making the groove formed on the outer periphery of the cylindrical part into which the fitting protrusion of the elastic protrusion fits into an annular shape, This prevents fluctuations in the elastic holding force when the battery receiving plate rotates, promoting smooth rotation, and preventing rattling or twisting of the battery receiving plate.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a main body case made of synthetic resin or the like with an open front end, and has a handle 2. Inside, a battery 3 and a radio receiving circuitry element (not shown) are housed. A sound emitting hole 4 is formed on the side wall, and a hanging hook member 5 is formed on the lower wall.

6 is made of synthetic resin, etc., and is connected to the main body case 1.
The lens cap is screwed into the front end opening 1a of the main body case 1, and the outer peripheral surface of the front end opening 1a of the main body case 1 and the inner peripheral surface of this lens cap 6 have threaded parts 7 and 8 that are screwed together. each formed. A lens body 10 having a hook-shaped portion 9 formed on its outer peripheral edge is firmly fixed to the lens cap 6 by insert molding of the hook-shaped portion 9. 1
Reference numeral 1 denotes a reflecting mirror formed by depositing a reflective layer 13 such as A on the front surface of a synthetic resin substrate 12, as shown in FIG. Flange portions 16 are formed respectively, and are press-fitted and fixed to the lens cap 6 via the flanges 16.

The reason why the reflecting mirror 11 is press-fitted and fixed by the flange 16 is to prevent the reflecting mirror 11 from being distorted and deformed during press-fitting.

Reference numeral 17 indicates a power switch for the light bulb 14, for example, a push button type switch, and reference numeral 18 indicates a recess for setting the switch formed in the upper wall of the main body case 1. Above recess 1
As shown in FIGS. 3 and 4, a switch fitting hole 20 surrounded by a cylindrical wall 19 is formed inside the 8, and a plurality of hollow boss portions 21 are formed on the outside of the cylindrical wall 19. It is located and protrudes. 2
2 is made of neoprene rubber, etc., and is connected to the switch 1 above.
7 is a waterproof cover that is fitted onto the flange 17a and covers the push button 23, and 24 is a switch press plate made of ABS resin or the like, with a switch cover through hole 25 formed in the center, and the hollow boss portion 21 on the bottom surface. A press-fit pin 26 corresponding to the above is provided in a protruding manner. With the push button 23 covered with the waterproof cover 22 and the switch 17 fitted into the switch fitting hole 20, the press-fit pin 26 is held until the switch presser plate 24 is fitted into the opening edge of the recess 18. By press-fitting into the hollow boss portion 21, the switch 17 and the waterproof cover 22 are attached to the main body case 1 side.

The switch holding plate 24 is curved into a concave shape so that it can be elastically deformed from the periphery toward the cover through hole 25, so that when the switch 17 is installed, the elastic reaction force of the concave portion 27 is applied to the switch. 17
This is to attach it to the side and firmly fix it. In this attached state, the waterproof cover 22 is prevented from wobbling with respect to the switch 17 by the wedge action of the inclined ribs 28 protruding from the inner wall of the cylindrical wall 19.
In addition, as shown in FIG. 5, elastic protrusions 29 made of polypropylene resin or the like are provided on the inner wall of each hollow boss portion 21.
If this is formed, the press-fitting condition of the press-fitting pin 26 becomes even more secure.

Reference numeral 30 denotes a synthetic resin battery receiving plate located on the front side of the battery 3 and disposed inside the main body case 1, and the battery receiving plate 30 has a circle around its outer circumference as shown in FIG. A reinforcing rib wall portion 31 is formed along the wall, and a light bulb holding tube portion 32 that is fitted into the tube portion 15 of the reflecting mirror 11 projects from approximately the center of the front surface of the rib wall portion 31 for reinforcement. The reason why the slotted portions 33 and 34 are formed in the cylindrical portion 32 is to enable elastic deformation when the cylindrical portion 32 is fitted into the cylindrical portion 15. Reference numeral 35 denotes a plurality of elastic protrusions arranged concentrically and evenly around the bulb holding cylindrical part 32, and the inner surface of the tips of these elastic protrusions 35 and the outer circumferential surface of the cylindrical part 15 of the reflecting mirror 11 are For example, an annular groove 36 continuous in the circumferential direction on the outer circumferential surface of the cylindrical portion 15 is provided, and an annular groove 36 is provided inside the tip of the other elastic protrusion 35.
A fitting protrusion 37 is formed which is fitted into the fitting protrusion 37 . The elastic protrusions 35 are formed by cutting out a part of the annular protruding wall 38 formed on the outside of the light bulb holding tube 32, but each elastic protrusion 35 may be formed individually. . Reference numerals 39 and 39 designate anti-rotation pieces protruding from the rear surface of the battery receiving plate 30, which abut against the inner wall side of the main body case 1 when the battery receiving plate 30 is disposed inside the main body case 1. This locks the battery receiving plate 30 to position it.

As shown in FIGS. 7 and 8, lead plates 40 to 42 are fused or caulked to the rear surface of the battery receiving plate 30 by protrusions 43 or the like. One end 40a, 41a of each lead plate 40, 41 extends to a position corresponding to the external terminal 44, 45 of the power switch 17, and the other end 40b, 41b
are extended to a position corresponding to one pole 3a of the battery 3 and a slot 33 corresponding to one electrode 14a of the light bulb 14, and the lead plate 42
One end 42a extends into the cylindrical portion 32 at a position corresponding to the other pole 3b of the battery 3, and the other end 42b corresponds to the other electrode 14b of the light bulb 14. 46 is a flange formed on the cylindrical portion 15 of the reflecting mirror 11 to prevent the light bulb 14 from coming off.

In order to assemble the battery receiving plate 30 into the main body case 1, as shown in FIG. If the rear end cylindrical portion 15 of the reflecting mirror 11 is double fitted and held between the pieces 35, the fitting protrusions 37 of each of the elastic protrusions 35 will fit into the annular groove 36 on the outer peripheral surface of the cylindrical portion 15. Therefore, the battery receiving plate 30 is rotatably attached to the reflecting mirror 11 as shown in FIG. 10, and further,
The light bulb 14 is secured to the flange 46 of the cylindrical portion 15, and the electrode portions 14a, 14b are brought into contact with the other ends 41b, 42b of the lead plates 41, 42, respectively. As a result, the light bulb 14 and battery receiving plate 30 are blocked together with the reflecting mirror 11 into the lens cap 6.

One end 40a, 41 of each lead plate 40, 41
a to the external terminals 44 and 45 of the power switch 17, respectively, and the lens cap 6
The battery receiving plate 30 can be placed inside the main case 1 by simply screwing it into the front end opening of the main case 1 as shown in the figure. That is, during the above-mentioned screw operation, the anti-rotation pieces 39, 39 of the battery receiving plate 30 come into contact with the inner wall of the shoulder portion of the main body case 1 as shown in FIG. 6 can be freely rotated with respect to the main body case 1, so when this lens cap 6 is rotated with respect to the main body case 1, the lead plate 42 on the rear surface of the battery receiving plate 30 and the battery 3 are connected. The screwing is performed while maintaining the abutting positional relationship, and as this lead plate 42 presses the battery 3, electricity is supplied to the battery 3, the light bulb 14, and the power switch 17 via each lead plate 40 to 42. connection is made.

To replace the battery, remove the lens cap 6 from the main body case 1 by performing the reverse operation to the above, and the lens cap 6 and the battery receiving plate 30 can be removed together with the lens cap 6.
Since the battery 3 can be removed from the main body case 1, the battery 3 inside the main body case 1 can be easily taken out.

Further, the battery receiving plate 30 has its cylindrical portion 32 and elastic protrusions 35 fitted internally and externally to both the inner and outer circumferential walls of the cylindrical portion 15 of the reflecting mirror 11, that is, the reflecting mirror 11
Since the binding part is double held against the cylindrical part 15 of the block, it can be reliably positioned in both the front-rear direction and the circumferential direction, and when this block is attached to the main body case 1, the battery 3 Even if a pressing force is applied from the side and a force is applied to the battery receiving plate 30 in a twisting direction using the cylindrical portion 15 as a fulcrum, the battery receiving plate 3
0 can prevent the light bulb 14 from misaligning with respect to the reflecting mirror 11, that is, the light bulb 14 may be out of focus, without causing any misalignment, and the light bulb 14 and the lead plate 4 can be placed on the battery receiving plate 30 that is securely positioned.
Since all of the lead plates 0 to 42 are attached, it is possible to prevent poor contact between the two and poor conduction between the lead plates 40 to 42 and the spot 3, and also to prevent the battery 3 from shaking due to insufficient pressure. There is no such thing.

Moreover, by making the groove 36 on the cylindrical portion 15 side into which the elastic protrusion 35 of the battery receiving plate 30 fits into a continuous annular groove in the circumferential direction, the fitting elastic holding force changes when the battery receiving plate 30 rotates. battery receiving plate 30 without
Wobbling can be prevented, unnecessary deformation of the elastic protrusion 35 can be suppressed, and smooth rotation operation force can be obtained.

As described above, according to this invention, not only can the battery receiving plate be attached and removed integrally with the lens cap, but also the battery receiving plate has a cylindrical portion that fits inside the reflecting lens barrel, and a concentric elastic ring that fits externally. Since it is double-fitted with the protruding piece, not only does it provide accurate rotational guidance without defocusing the bulb, but also the prying force applied to the battery receiving plate when installed is reduced by the internally fitting cylindrical part. Since it is absorbed, the elastic projecting piece of the outer fitting does not deform unnecessarily or remain deformed, and the elastic holding force can be prevented from decreasing.

In addition, the fitting protrusion of the elastic protrusion when installed is made to have an annular groove on the mating reflector barrel, so that the battery receiving plate can be rotated smoothly without fluctuations in the elastic holding force. This allows the lens cap to be screwed on smoothly.
