Description

[Detailed Description of the Invention] This invention relates to a blinking operation string hanging from a lighting fixture using fluorescent lamps.

During the day when this type of string is not in use, it should be placed at a height that does not interfere with the faces and heads of people who are standing or walking, and at night, if desired, It is desirable that the hanging length of the string can be adjusted over a wide range so that the device can be operated even when lying on the bed. However, the reality is that even if we search for products on the market that can meet these demands, we cannot find any.

It can be expected that in order to vary the hanging length of the string over a wide range, it is enough to wrap the string with one end fixed around the two guide members several times, but the problem is that the length of the string cannot be adjusted to a certain length. However, how can the string be set to this adjustable length, and can be easily and reliably locked so that it will not shift due to the tension when the force required to operate the lighting equipment is applied as a tensile force to the string. There is a crab.

This invention was made for the purpose of solving the above-mentioned problems, and has the following configuration. That is, a vertical through hole;
a guide member having a vertical through hole that does not intersect with the horizontal through hole, and a bottomed horizontal hole that is shifted in phase substantially at right angles to the direction of the horizontal through hole and intersects with the vertical through hole; It consists of an operating rod with a vertical hole that can communicate with the vertical through hole when pushed against a spring loaded into the horizontal hole, and a string with one end fixed to a plate-like piece. This is a blinking operating string for a fluorescent lighting fixture, which is first passed through a horizontal through hole, then through a hole in a plate-like piece, and then hung down through a vertical through hole and a vertical hole.

This invention will be explained below with reference to embodiments shown in the drawings.

The guide member 1 made of plastic etc. has a second
As shown in the figure, there are three holes, namely a horizontal through hole 2,
A vertical through hole 3 that does not intersect with the horizontal through hole 2, and a bottomed horizontal hole 4 that intersects with the vertical through hole 3 and are shifted in phase almost at right angles to the direction of the horizontal through hole 2. do. A spring 5 is loaded into the bottom of this horizontal hole 4,
Further, the operating rod 6, which is pressed by the spring 5, is inserted into the horizontal hole 4. The operating rod 6 has a spring 5 attached to it.
Vertical through hole 3 only opens when pushed in against force.
However, when the pressing force is released, a vertical hole 7 is formed that deviates from the center line of the vertical through hole 3. The operating rod 6 is fitted into the horizontal hole 4 somewhat loosely. This is because, as will be described later, in this invention, the locking force is obtained by biting the part of the string 10 protruding from the top and bottom of the vertical hole 7 into the annular gap between the horizontal hole 4 and the operating rod 6. This is because an annular gap portion of 1 is required. The horizontal hole 4 and the operating rod 6 may have a circular cross section or a square cross section. Further, the bottomed horizontal hole 4 may be formed by inserting a plug into one end of the through hole (not shown).

Next is the plate-shaped piece 8, which has three holes 9, 9a, and 9b.The top hole 9b is used for connection to the lighting equipment side, and the middle hole is used for connection to the lighting equipment side. 9a is used to fasten one end of the string 10. The lowermost hole 9 is used to pass a string 10, one end of which is fixed to the plate-shaped piece 8, through the horizontal through-hole 2 of the guide member 1, and then through the hole 9. After passing through the hole 9, the string 10 is inserted through the vertical through hole 3 of the guide member 1 and the vertical hole 7 of the operating rod 6 in a state where they are in communication with each other, and is allowed to hang down. In addition, in the figure, 11 is a weight body attached to the lower end of the string 10.

The effects of the above-mentioned operating cord will be explained as follows.

In the normal state, the operating rod 6 is pushed forward by the spring 5 and tries to move forward along with the string 10 inserted into the vertical hole 7, so the portion of the string 10 that extends above and below the vertical hole 7 is It is pulled into the annular gap between the horizontal hole 4 and the operating rod 6. This biting locks the operating rod 6 in place, as shown in FIG. 3.

At this time, the string 10 is bitten tightly in proportion to the force of the spring 5, so
It can sufficiently withstand the pulling force of the string 10 required for blinking the lighting equipment, and it has never happened that the desired blinking operation cannot be performed just by the string 10 moving slowly.

When you want to adjust the hanging length of the string 10, push the operating rod 6 deep against the spring 5 to release the above-described locking of the string 10, and then connect the vertical through hole 3 and the vertical hole 7. After communicating with each other, the part of the string 10 that hangs down is pulled down to stretch it, or the guide member 1 is pulled down to shorten the string 10. In this case, when the string 10 is pulled down until the guide member 1 collides with the plate-like piece 8, the entire length of the string 10 is stretched, making it accessible even when lying down.
When the string 10 is pulled up until they collide, the total length of the string 10 becomes the minimum drooping length of the string 10 folded into three.

In this way, it can be provided relatively easily and inexpensively,
Moreover, the hanging length of the string can be adjusted over a wide range, and the set hanging length of the string does not change even when the blinking operation is performed.
This invention has excellent practical effects as a blinking control string for fluorescent lighting equipment.
