Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tool for handling straight ring lamps, in particular for replacing or cleaning fluorescent lamps.

Conventional technology Previously, replacing fluorescent lights installed in difficult-to-reach locations, such as ceilings, had to be done directly by hand, standing on a stand.

In other words, get up on a nearby chair, desk, or stepladder, then reach out and grasp the lamp with both hands, and lift the lamp against the urging force of the jig that supports and energizes the caps at both ends of the lamp. Remove the pin on one end of the lamp from the jig by pressing it against the other jig, then get off the chair or desk, place the removed lamp on the floor or lean it against the wall, and then hold the new lamp in your hand. He climbed onto the stand again, gripped the lamp with both hands, and pressed it against one side of the jig as he attached it.

To clean fluorescent lamps, I either went up to the stand, reached out to the lamp, and wiped it with a chemical cloth, or I removed the lamp, polished it, and then put it back on the jig.

Problems that the invention aims to solve However, the method of replacing fluorescent lamps directly by hand has the following problems.

Climbing onto a platform such as a chair, desk, stepladder, etc., reaching out, and even tipping your toes to replace a lamp means working in an unstable position on an unstable platform, which is a safety hazard. There's a problem. This is especially true in offices where there is usually a desk directly under the fluorescent lights, the desk is not strong enough for a person to sit on, and there are often piles of documents on the desk. , when it comes to nearby tables, the only table you can often find is a swivel chair. In such a case, it is extremely dangerous to climb up on a rotating chair and replace the fluorescent lamp in an awkward position.

Using a chair or desk for anything other than its intended purpose is not a good idea and can not only pose a danger to the worker performing the replacement as described above, but also damage the chair or desk.

Furthermore, even in cases where it is not a safety problem to climb up on a chair or desk to replace the lamp, putting the removed lamp down, picking up a new lamp, and reinstalling it takes a lot of effort, and it is difficult to replace the lamp. Replacing even a single lamp can be very tiring and can cause dirt to get into the eyes, as replacement work is done with the body fully stretched out and the head turned almost directly upwards.

Replacing several lamps can be tiring, increase the risk of getting dirt in your eyes, and require more effort to move the lamps.

As described above, replacing fluorescent lamps is a surprisingly time-consuming task, and is a task that women and elderly people in particular do not like.

In addition, cleaning fluorescent lamps requires more effort than the above-mentioned replacement work because a large number of fluorescent lamps must be cleaned one after another.

In view of this situation, the present invention was developed as a result of extensive research aimed at providing a tool that allows fluorescent lamp replacement or cleaning work to be carried out while standing on the floor.

Means for Solving the Problems The straight-ring lamp handling tool of the present invention has a cylindrical gripping portion 2 divided into two gutter-like divided pieces 2a and 2b at the tip of a rod-like handle 1. 1 and in a T-shape in relation to the handle 1, and at least the inner surface of the cylindrical grip part 2 is made of a material having cushioning properties, or the cylindrical grip part 2 is
A cushioning material 4 is attached to the inner surface of the handle 1, and an operating section 3 for switching the cylindrical grip section 2 between an open state and a closed state is provided at an appropriate portion of the handle 1.

The handling tool of the present invention can be applied to a straight ring (right cylindrical) lamp. Not only the case where the lamp has a straight ring shape over the entire length, but also the case where a part of the lamp has a straight ring shape is sufficient.

A typical lamp is a fluorescent lamp, but other types of lamps such as high-pressure discharge lamps, ultra-high-pressure discharge lamps, low-pressure sodium lamps, and xenon lamps can also be used depending on their shape.

The present invention will be explained below based on the drawings.

FIG. 1 is a side view showing the straight-ring lamp handling tool in Example 1, in which A shows the tool in the open state and B shows the tool in the closed state.

1 is a rod-shaped handle, which is made of metal (aluminum alloy, etc.), plastics, plastics reinforced with glass fiber or carbon fiber, bamboo, wood, etc. To reduce weight, it is usually hollow.

In addition to being a single handle, the handle 1 can be divided into a base side and a distal side, foldable, or connectable with an auxiliary handle for use at high places, in consideration of portability or storage. .

If the handle 1 is made splittable or foldable, it is better to provide the handle 1 closer to the distal end than the split or foldable part of the handle 1 in order to reduce the complexity of the linkage structure between the cylindrical grip part 2 and the handle part 3. It's advantageous.

2 is a cylindrical gripping part, and two gutter-shaped divided pieces 2
It is divided into two parts a and 2b.

The cylindrical gripping part 2 is provided at the tip of the rod-shaped handle 1 so as to be perpendicular to the axial direction of the handle 1, and so that the handle 1 and the cylindrical gripping part 2 form a T-shape. It is desirable that both edges of the inner surface of the cylindrical gripping part 2 be rounded so as not to damage the lamp.

Reference numeral 4 denotes a cushioning material to prevent the lamp from being damaged when the lamp is held between the cylindrical gripping portions 2. Examples of the material for the cushioning material 4 include nonwoven fabric, artificial leather, knitted fabric, net, rubber, plastics, foam, three-dimensional network structure, and cork.

The cushioning material 4 is provided by each divided piece 2a, 2b of the cylindrical grip part 2.
Although it is often made to have approximately the same size as , it may be made to slightly protrude from both end faces of the cylindrical grip part 2 so as not to damage the lamp at the end faces of the cylindrical grip part 2 .

When the entire cylindrical grip portion 2 or at least the inner surface thereof is made of a material having cushioning properties, the provision of the cushioning material 4 can be omitted. A material having cushioning properties is one that is hard enough not to damage the lamp when it is sandwiched between the lamps.

Reference numeral 3 denotes an operating section provided at an appropriate portion of the handle 1.
The operating portion 3 is often provided on the proximal end of the handle 1 or within a range of 2/3 of the total length from the proximal end toward the distal end. FIG. 1 shows a case where the operating section 3 is provided near the base end of the handle 1.

The operating portion 3 may be detachably attached to the handle 1 or may be slidable in the length direction of the handle 1, depending on the case.

This operation section 3 is for switching the cylindrical grip section 2 between an open state and a closed state, and is of a trigger operation type,
Various operating methods can be adopted, such as rotary operating type, button operating type, and sliding operating type.

The operating section 3 and the cylindrical grip section 2 are linked by a linking member 5 such as a wire, rope, rod, or crank, or are electrically powered using a small motor, so that the operating section 3 can be operated or commanded. is transmitted to the opening and closing of the cylindrical grip part 2. The linking member 5, such as a wire, rope, rod, or crank, may be passed through the handle 1 either inside or outside.

The opening/closing operation of the cylindrical gripping part 2 is such that the cylindrical gripping part 2 is normally in an open state and can be switched to the closed state by operating the operating section 3, or the cylindrical gripping part 2 is normally in a closed state and cannot be operated. It may be any type that can be switched to the open state by operating the section 3.

After operating the operating part 3, the method for returning the cylindrical grip part 2 and the operating part 3 to the normal state is to
Alternatively, a method that uses the weight of the operating section 3, a method that attaches a return spring to the cylindrical grip section 2 or the operating section 3, and utilizes the biasing force of the spring, etc. are adopted.

The handling tool of the present invention is useful for replacing straight ring lamps, especially fluorescent lamps, but can also be used for cleaning them. In this case, it is advantageous to use a chemical rag as the cushioning material 4 attached to the inner surface of the cylindrical gripping part 2. It is also possible to use it for replacing fluorescent lights while wearing a chemical rag for cleaning.

Function To replace a straight ring lamp, such as a fluorescent lamp, using the handling tool of the present invention, hold the rod-shaped handle 1 with both hands and extend it toward the lamp, and open the cylindrical grip part 2. The lamp is placed in the open cylindrical grip part 2, and then the lamp is firmly held by operating the operation part 3 to close the cylindrical grip part 2. Then, move the handle 1 in the length direction of the lamp (that is, the length direction of the cylindrical grip part 2), press the lamp to one side against the urging force of the jig, and tighten the pins on one of the caps of the lamp. Remove the lamp from the fixture as well as the entire lamp.

While holding the removed lamp, move handle 1,
Operate the operating section 3 to open the cylindrical grip section 2 and remove the lamp.

Next, open and close the cylindrical gripping part 2 to grasp a new lamp, and while touching the cap at one end of the lamp to one of the jigs, press the lamp against one of the jigs against the urging force of the jigs. Fit the cap on the other end of the lamp into the other jig. Next, by operating the operating section 3 to open the cylindrical grip section 2, the lamp can be replaced.

When cleaning the lamp, attach a cushioning material 4 such as a chemical rag to the cylindrical grip part 2, extend the handle 1 to the lamp, operate the operating part 3 to grasp the lamp, and simultaneously move the lamp in the axial direction several times. All you have to do is slide it back and forth.

After the cleaning is completed, the operation section 3 is operated to open the cylindrical grip section 2, and the next step is to clean the lamp.

All of the above operations can be performed while standing on the floor.
