Description

[Detailed explanation of the invention] [Industrial field of application] When a light bulb explodes due to carelessness on the part of the user, the screw cap of the broken light bulb remains in the socket, and this screw cap is used to install a new light bulb. It is necessary to remove the cap. The present invention relates to a light bulb cap removal tool for easily removing the screw cap.

[Conventional technology]

Conventionally, the screw cap of a broken light bulb remaining in the socket was forcibly removed by applying a rag or the like to the socket or using pliers to prevent injury.

[Problem that the invention attempts to solve]

Since the base of the light bulb does not protrude from the socket, or even if it does protrude only slightly, it is extremely difficult to apply rotational force to the screw base of this broken light bulb using the above conventional means, making it difficult to remove the base. If you remove it forcibly using pliers, etc., the socket itself will be damaged.

The present invention aims to provide a light bulb cap removal tool that is devised so that the screw cap of a broken light bulb can be easily removed.

[Means for solving problems]

The technical means of the present invention taken to solve the above-mentioned problems is that an elastic body shaped to fit into the screw cap of the light bulb is provided on the tip side of the operation part.

[Effect]

As a result of taking the above technical means, by pressing the elastic body into the screw cap of the broken light bulb, the elastic body and the cap become integrated, and the screw cap can be rotated as the operating part rotates.

[Effect of idea]

According to the above means of the present invention, there is no need to worry about breaking the socket as in the conventional case, and even if the socket is tightly screwed into the socket, it can be easily removed, and the glass remaining in the socket can be removed. Workers will not be injured by the pieces.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 of the drawings shows a light bulb cap remover according to a first embodiment of the present invention. In this first embodiment, the operation part 1 is made of a hard cylindrical member made of synthetic resin or metal coated with an insulating coating. A rubber elastic body 2 whose tip is shaped to fit is integrally provided with a fixing means such as screws 3 or adhesive. Further, a fitting hole 1a is provided on the rear end side of the operating portion 1 as a connecting portion for connecting an operation aid 4 made of a rod-shaped body that can be expanded and contracted in multiple stages. , a detent pin 5 that fits into the tip of the auxiliary tool 4 inserted into the insertion hole 1a to reliably transmit the rotational operating force of the auxiliary tool 4 to the operating section 1; and an operation aid 4.
A tightening bolt 6 is provided as a fixing means for connecting and disconnecting the controller 1 to the operating section 1.

Figure 2 shows how the light bulb cap remover is used in the first embodiment. When the high beam bulb A (an example of a light bulb) installed at a high place explodes, the light bulb cap remover remains in the socket 7. A state in which the ivy screw-in fitting a is being removed using the operation aid 4 is shown. When the cap a is within reach, there is no need to use the operation aid 4.
The shape of the elastic body 2 may be exactly the same as the inner shape of the screw cap a, or may have a different shape, such as a square prism or a pentagonal prism, but this first embodiment If the tip of the elastic body 2 is shaped into a wedge shape as shown in the figure, even if the pressing force when pressing it against the inner peripheral surface of the mouthpiece a is relatively small, the rotational operation can be performed by increasing the frictional force using the wedge effect. It has the advantage of being easy to transmit force.

Another embodiment of the present invention will be described below. FIG. 3 of the drawings shows a light bulb cap remover according to a second embodiment of the present invention. This second embodiment is
This embodiment differs from the first embodiment in that the elastic body 2 includes a flange 2a that comes into contact with the opening edge of the screw cap a. With such a flange 2a, when the elastic body 2 is pushed into the ferrule a, not only does the elastic body 2 come into close contact with the ferrule a, but also the glass piece b remaining in the ferrule a is removed from the flange. Since it bites into the portion 2a, it has the effect of making it easier to transmit the rotational operating force to the screw cap a.

FIG. 4 of the drawings shows a light bulb base remover according to a third embodiment of the present invention. This third embodiment is different from the first embodiment in that the elastic body 2 has a space 2b in its center that opens toward the distal end side of the elastic body 2, and the inner part of this space 2b is The inner diameter of the filament is smaller than, for example, the support leg c of the filament, which is called the stem tube of an incandescent light bulb (an example of a light bulb) A. By providing such an open space 2b, there is no need to remove the support leg c when using the light bulb cap remover, and the support leg c can be used to hold the cap a.
Even if the insertion depth of the elastic body 2 into the mouthpiece a is shallow, safe removal can be performed.

Although not shown in the drawings, as another embodiment of the elastic body 2, one with a shape slightly smaller than the inner shape of the base a may be adopted. In this case, the elastic body 2 may be made of relatively soft rubber or the like. When this elastic body 2 is pressed against the inner part of the mouthpiece a, the elastic body 2 is expanded in the lateral direction and brought into contact with the inner circumferential surface of the mouthpiece a, and the resulting frictional force is used for rotational operation. It may be configured to transmit force to the cap a. As another example, an uneven portion may be provided on the circumferential surface of the elastic body 2 to make it easier to follow the inner circumferential surface of the base a and to provide an anti-slip effect.
