Description

[Detailed Description of the Invention] The present invention relates to a light bulb remover for removing a damaged light bulb installed at a high place.

Incandescent light bulbs are often used in street lights from the viewpoint of economy, but their lifespan is about 1000 hours, so they must be replaced at short intervals of approximately one year or less.

However, since these street lights are installed at high places such as telephone poles, it is inconvenient to replace them. Therefore, the inventor of the present invention previously proposed a method for replacing street lights extremely easily but without damaging the light bulbs. We developed a light bulb changer for changing light bulbs.

However, this light bulb changer has a grip attached to the tip that has a claw that wraps around the glass part of the light bulb to prevent it from slipping, so it is not possible to remove a light bulb with a damaged glass part. Ta.

Therefore, an object of the present invention is to provide a light bulb remover that allows the light bulb to be removed even if the glass part is damaged.

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

1 is a light bulb holder made of a resin material for mounting and removing an incandescent light bulb whose glass part is not damaged, and a claw piece 1a divided into four pieces in the radial direction is formed on the upper part of the light bulb holder. The claw piece 1a is curved outward 1 side corresponding to the outer shape of the spherical part of the glass part of the light bulb, and a rubber 2 is fitted into the elongated hole formed in the vertical direction.

A protrusion 1b is formed at the tip of the claw piece 1a so that the entire claw part 1a bends outward with elasticity when inserted into a light bulb.

Reference numeral 1C denotes a base, in which a stop hole 1d is formed to prevent the entire rod from rotating and from being pulled out when it is fitted into the fitting body 4 at the tip of the rod 3.

The rod 3 is made of a long pipe whose entire length can be adjusted by an adjustment part (not shown), and a fitting body 4 that fits into the gripping body 1 is fixed to the tip of the rod by a screw 5 in a non-removable and non-rotatable manner. Further, a conical rubber tube 6 is bonded to the tip of the fitting body 4 with adhesive.

The axial hole 6a of the rubber cylinder 6 communicates with the hole 4a at the tip of the fitting body 4.

Further, the diameter of the hole 6a at the tip of the rubber tube 6 is reduced, making the elasticity stronger.

A lock pin 7 is inserted into the side hole 4C from the direction of the inner wall 4b of the fitted body 4, and is prevented from being pulled out outward by its large diameter portion 7a, and the lock pin 7 is in pressure contact with the inner wall 4b of the fitted body 4. The lower diameter portion 7a is pressed by the letter-shaped leaf spring 8, so that it is always urged outward.

Note that 7b is a projection inserted into the leaf spring 8 to prevent the leaf spring 8 from moving up and down.

In the above, in order to remove an incandescent light bulb installed at a high place, while holding down the lock pin 7 of the fitting body 4 at the tip of the rod 3, fit the base of the gripping body 1 into the fitting body 4, The lock pin 7 (Lld) should match and protrude from there.

As a result, the gripping body 1 is securely attached to the fitting body 4, and the lower portion of the rod 3 is held to fit the claw piece 1a of the gripping body 1 into the incandescent light bulb.

At the time of this fitting, the protrusion 1b is pushed and expanded by the force-welded portion, so that the rubber 2 once escapes from the glass portion and is then crimped onto the glass portion.

Therefore, if you twist the rod to the left in state 2, the light bulb will come out of the socket.

When installing a light bulb, it is best to do the opposite operation.

Next, if the glass part of the light bulb you are trying to remove is damaged, remove the grip 1 from the fitting body 4, and in this state insert the rubber tube 6 into the stem 9 where the light bulb remains.
Press further and twist the lower part of the rod 3 to the left.

This will allow the bulb to pop out of the socket.

At this time, the rubber tube 6 is crimped to the base of the bulb's stem 9 with great force, so it will not slip there, and the small diameter part at the tip will not buckle, and the screw part 10 of the bulb can be easily screwed. It comes off the socket.

Here, the tip of the rubber tube 6 does not necessarily have to fit between the base of the stem 9 of the light bulb and the threaded part 10, but the removal work is made easier by making it press against the edge 10a of the threaded part 10. become.

As described above, according to the present invention, it becomes possible to easily remove a light bulb that has been installed at a high place and has a damaged glass portion.
