Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tool for removing or attaching fluorescent lamps located at high places to appliances in offices, factories, etc.

Generally, in offices, factories, etc., many fluorescent lamp fixtures are installed on the ceiling, and fluorescent lights are attached to these fixtures. When a fluorescent lamp reaches the end of its lifespan, its brightness decreases and it starts blinking, so it must be replaced with a new one, but each fluorescent lamp has a different lifespan and is located in a high place. As a result, workers had to climb onto the pedestals and replace them one by one, which was very troublesome and extremely inefficient. In particular, depending on the location of a desk or desk in an office, or the location of machinery in a factory, it is often not possible to place a footrest under a fluorescent light. Replacement involved great difficulties such as moving desks and the like.

Therefore, the present invention provides a fluorescent lamp holding rod that is installed horizontally at the upper end of the handle member, a fluorescent lamp holding member that is disposed on the holding rod, and a fluorescent lamp holding member that is attached to a holding member that has a pair of holding parts. and an operating part thereof, and the clamping part is slidably disposed on the holding rod, and the operating part is fixedly disposed on the holding rod, and either of the clamping part and the operating part A cam part is provided on one side, and an actuating part that comes into contact with the cam part is provided on the other side, and the pressing action of the actuating part based on the movement of the holding rod in the axial direction by the handle member causes the pair of clamping pieces to move. configured to grip the fluorescent lamp and move the fluorescent lamp with the retaining rod relative to the fluorescent lamp fixture;
To provide a fluorescent lamp exchanger which allows the fluorescent lamp to be easily exchanged on the floor without climbing on a stool or the like.

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

As shown in FIGS. 1 and 3, the fluorescent lamp exchanger 1 has a long handle member 2, and a fluorescent lamp holding rod 3 is attached to the upper end of the handle member 2. They are mounted so that they are perpendicular to each other, and the mounting angle can be set appropriately using a hinge joint 5 and a wing nut 6. The holding rod 3 is made of, for example, a single stainless steel pipe, and fluorescent lamp holding members 7 having the same structure are disposed near the left and right ends of the holding rod 3, and the fluorescent lamp holding member 7 has a pair of holding parts. It consists of a clamping part 10 having pieces 9a and 9b, and an operating part 11 thereof. More specifically, the clamping part 10 of the fluorescent lamp clamping member 7 is mounted on a base 12 that is slidably guided by the holding rod 3, and includes two clamping parts 9a made of, for example, a vinyl chloride board. 9b are planted slightly apart from each other, and the clamping pieces 9
As shown in detail in FIGS. 2 and 3, on the upper portions of a and 9b, there are fluorescent lamps F to which cushioning materials 13a and 13b, such as sponges or rubber plates, are adhered, respectively.
Support portions 15a and 15b are formed. Further, cam portions 16a, 16b which are inclined toward the actuating portion 11 side are integrally formed approximately at the center of the side portions of the clamping portion pieces 9a, 9b. Furthermore, a sliding piece 17 is integrally protruded from the lower part of the base 12, and the sliding piece 17 is slidably fitted into a guide groove 19a of a guiding piece 19 fixed to the holding rod 3. Together, the clamping part 10
is configured so that it does not rotate with respect to the holding rod 3. On the other hand, the actuating part 11 has a base part 20 fixed to the holding rod 3, and a relatively hard spring material, for example, is attached to the upper end of the base part 20 so as to face the clamping part 10. A pair of actuating parts 21 made of
a, 21b are provided in a protruding manner, and the pair of actuating parts 21a, 21b actuate the aforementioned clamping parts 9a, 9.
The cam portions 16a and 16b provided on the b side are pressed from outside via a roller 22. In addition, what is indicated by the reference numeral 23 in FIG. 1 is a fluorescent lamp fixture that holds the fluorescent lamp F and energizes it.

Since the present fluorescent lamp exchanger 1 has the above-described configuration, in order to remove the fluorescent lamp F from the fluorescent lamp fixture 23, the operator must hold the handle member 2, as shown in FIG. , support parts 15a and 15b at the upper end of each clamping part 10

is exposed to fluorescent light F. At this time, depending on the position of the instrument 23 and the worker, the support parts 15a and 15 are
Adjust the angle with the wing nut 6 so that the point b can receive the fluorescent light F. And the support part 15a,
15b is slightly pressed against the fluorescent lamp F, the handle member 2 is moved to the holding rod 3 as shown by arrow A in FIG.
When the clamping part 10 moves in the axial direction of the clamping part 10, its movement is stopped due to frictional contact between the buffer materials 13a, 13b on the inner surfaces of the supporting parts 15a, 15b and the fluorescent lamp F. is moved relative to. Then, based on the wedge action of the cam parts 16a, 16b, the actuating parts 21a, 2 of the actuating part 11
1b strongly presses the clamping pieces 9a and 9b from both sides, so that the clamping pieces 9a and 9b, which had been facing each other in a slightly open manner, are pressed toward each other in a slightly closed manner. The fluorescent lamp F is firmly held between the support parts 15a and 15b of the holding pieces 9a and 9b. When the handle member 2 is further moved in the A direction in this state, the fluorescent lamp F is also moved in the A direction with respect to the fixture 23, so that the terminal part on the opposite side to the moving direction of the fluorescent lamp F is connected to the socket part of the fixture 23. come off from From this state, when the handle member 2 is slightly tilted to completely remove the fluorescent lamp F end from the fixture 23 and the handle member 2 is retreated in the opposite direction of arrow A, the other end of the fluorescent lamp F is also attached to the fixture 23. removed from the socket. As a result, the fluorescent lamp F is completely removed from the fixture 23, and the operator can easily retrieve the removed fluorescent lamp F from the exchanger 1 by pulling the holding rod 3 toward his/her hand. can.

Furthermore, in order to attach the fluorescent lamp F to the fixture 23, the operation may be performed in the opposite manner to that described above. That is, both gripping parts 10
With a new fluorescent lamp F placed on the supporting parts 15a and 15b of Fit it into the socket part of. In this state, the handle member 2 is moved in the direction of arrow A while resisting the spring of the socket portion of the instrument 23, and further in this state, the other end of the fluorescent lamp F is aligned with the other end socket portion of the instrument 23. Then, when the pressure on the handle member 2 is stopped in this state, the fluorescent lamp F is moved in the opposite direction of arrow A by the spring of the instrument socket portion, and the fluorescent lamp F is completely attached to the instrument 23. In this state, the pressing action of the actuating part 11 on the clamping part 10 is released, so by pulling the handle member 2 downward, the clamping part 10 can be easily removed from the fluorescent lamp F. The replacement work is completed.

Further, in the above-described embodiment, the fluorescent lamp exchanger 1 was shown in which fluorescent lamp holding members 7 of the same structure were disposed near both left and right ends of the holding rod 3, but as shown in FIG.
A fluorescent lamp holding member 7 may be disposed directly above the handle member 2, that is, at the center of the holding rod 3, and fluorescent lamp supporting members 25 may be provided near both left and right ends of the holding rod 3.
Then, the base 20 may be omitted and the pair of actuating parts 21a may be directly provided on the guide piece 19, and furthermore, as shown by the chain line in FIG. 3, the stopper S is removably installed on the guide piece 19, The degree of opening of the support portions 15a and 15b may be adjusted to correspond to the thickness of the fluorescent lamp F, that is, for a large tube or a thin tube. Further, as shown in FIG. 5, a fork-shaped member 26 inserted between the terminal part of the fluorescent lamp F and the socket part of the fixture 23 is held upright at the end of the holding rod 3 in the direction opposite to the arrow A by a soft spring or the like. When the handle member 2 is moved in the direction A, the fork-like member 26 rotates in the direction of the arrow B, thereby pressing the socket part and releasing the terminal part of the fluorescent lamp F. The utensil 23
It can also be made easier to remove from the socket.

As explained above, according to the present invention, the worker carries out the work of replacing the fluorescent lamp F by holding the handle member 2, so that even when the fluorescent lamp F is located at a high place, the worker does not have to climb on a stool or the like and can do it on the floor. The replacement work can be done easily and safely at the desk, and even in places where the legs cannot be placed because they are obstructed by a desk or machine, the handle member 2 can be extended from the side and the retaining rod 3 can be attached to a fluorescent lamp. It can be easily replaced by facing F. Furthermore, with the fluorescent lamp F supported by the clamping member 7, by simply holding the handle member 2 and moving it slightly in the lateral direction, the fluorescent lamp F will be firmly clamped by the clamping member 7, so that the fluorescent lamp F will not emit light. Replacing the lamp F can be carried out extremely easily and quickly, especially in office buildings where the ceiling is relatively low and the fluorescent lamp fixture 23 is installed directly on the ceiling board or is installed by being pushed into the ceiling. It is suitable for use in cases where the fluorescent lamp F
The efficiency of the replacement work can be greatly improved, and the structure is simple and can be manufactured at low cost.
