Abstract

<P>PROBLEM TO BE SOLVED: To provide a pull string operating device capable of adjusting the length of a pull string of a switching arrangement for a luminaire according to its use, simply and safely operable even by a child, inexpensive because of its simple structure, and attractive in its appearance. <P>SOLUTION: In this pull string operating device, a pulley mechanism formed by combining a pull string with a stationary pulley and a movable pulley is used, the length of the pull string between the knob part and the stationary pulley can be increased by several times of the original length by using a plurality of movable pulleys. Thereby, since a sufficient length can be given to the string, a user can obtain a string with a sufficient length by which operation for lighting and putting out lights is possible after the user is tucked in a bed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a drawstring operating member such as a lighting device attached to a wall surface, a ceiling or the like.

Conventionally, the switch device for lighting fixtures has been performed by attaching a string to a switch and pulling it. And in order to make this operation easy, the thing of the drawstring apparatus which enabled adjustment of the length of the drawstring to hang down is known.

However, since the length of the pull string of this pull string device is not sufficient and the adjustment range is narrow, it was necessary to stand up and disappear after entering a futon and reading a book before going to bed.

Japanese Utility Model Laid-Open No. 6-21129 (page 2, FIGS. 1 and 2) Japanese Patent Application Laid-Open No. 2004-95367 (page 10, FIG. 3)

In order to facilitate this operation, which is performed by attaching a string to the switch and pulling the switch, the conventional switch device for lighting fixtures has a drawstring device that allows the length of the drawstring to be adjusted to the drawstring that hangs down. What is installed is known. However, since the length of the drawstring of this drawstring device is short and the adjustment range is narrow, after entering a futon and reading a book etc. before going to bed, you have to stand up and operate because the length of the drawstring is insufficient. I had to. In order to solve this problem, devices such as attaching a long string to the switch device or attaching a remote control have been devised, but the long string is obstructive and may get caught in clothing etc. and damage the switch device. Installation has the disadvantage of increasing the economic burden.

An object of the present invention is to provide a drawstring operating device that can be adjusted in length according to the use, can be easily and safely operated by a child, has a low cost, has a simple structure, and has a good appearance.

In order to solve the above-described problems, the present invention utilizes a mechanism of a pulley that combines a fixed pulley and a string hung on a moving pulley, and uses a plurality of moving pulleys to draw a pull string between the knob and the fixed pulley. Can be made several times longer, the length of the drawstring can be taken sufficiently, and the operation of turning on and off can be performed after entering the futon.
In the drawing, in the pull string operating device comprising the two constant pulleys 5 and 6 in the upper fixed pulley section, the two movable pulleys 7 and 8 in the lower movable pulley section, and the pull string 3 passed between the pulleys, The length (H1) of the pulling string between the fixed pulley A and the knob C is lowered by pulling the pulling string downward, so that the length (H2) of the pulling string between the fixed pulley A and the knob C is the moving pulley 2. In the case of individual use, it becomes 4 times, and after going into a futon and reading a book etc. before going to bed, it is possible to turn on / off the light.

The present invention has the following effects.
1. By putting the drawstring in a stretched state, the lighting can be turned on and off after entering the futon.

2. By pulling the drawstring in a contracted state, it does not get in the way and it does not get caught by the string, so it is safe.

Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 5.

FIG. 1 is a front view of a drawstring operating device showing an embodiment of the present invention. FIG. 1 (a) shows a state in which the knob C is lowered to the lowest position and the drawstring 3 is made the longest. The figure is a front view showing a state where the lower movable pulley portion B is lowered, the knob portion C is raised, and the drawstring 3 is shortened.

FIG. 2 is a schematic diagram illustrating a path through which a pull string is passed through a fixed pulley and a movable pulley.

3 to 5 are diagrams for explaining the details of the embodiment of the drawstring scanning device.

  The drawstring operating device of the present invention connects and holds the upper fixed pulley portion A via the connecting ring 2 to the illumination drawstring 1 connected to the switch portion of the luminaire, and the lower movable pulley portion B and the knob portion. C is connected and held by the drawstring 3.

The upper fixed pulley portion A includes an upper case 9, an upper cover 10, fixed pulleys 5 and 6, a sleeve 13, a drawstring sleeve 14, and a mounting bolt 15.
The lower moving pulley portion B includes a lower case 11, a lower cover 12, moving pulleys 7 and 8, a sleeve 6, and a mounting bolt 15.

  The knob portion C is composed of a knob 4 and a pull string 3, and a knot portion 3a on one side of the pull string 3 is stored and fixed in a storage portion 4a of the knob 4, and the other knot portion 3b of the pull string 3 is a moving pulley. 7, 8 and fixed pulleys 5 and 6 are fixed to the drawstring rod portion 9b of the upper cover 10.

A process of assembling the drawstring operating device will be described with reference to FIGS.
First, the knot portion 3 b of the drawstring 3 is inserted into the drawstring rod portion 9 b of the upper case 9 and is pressed and fixed by the drawstring sleeve 14.

The fixed pulley 5, the sleeve 13, and the fixed pulley 6 are sequentially inserted into the fixed pulley rod portion 9 a on the upper case 9, and then the movable pulley 7 and the sleeve 13 are inserted into the movable pulley rod portion 11 a on the lower case. Then, the movable pulley 8 is inserted sequentially.

Starting from the drawstring 3 fixed to the drawstring rod portion 9b, according to the drawstring path shown in FIG. 2, the movable pulley 7, the fixed pulley 5, the movable pulley 8, the fixed pulley 6 and the drawstring 3 are sequentially passed through. Finally, after passing through the lower groove of the lower case 11, the upper cover 10 and the lower cover 12 cover and hold, and the mounting bolts 15 connect and fix the cases 9 and 11 and the covers 10 and 12.

The pull string operating device can be operated for a longest time by fixing the upper pulley portion A and lowering the knob C until the upper fixed pulley portion A and the lower movable pulley portion B come into close contact with each other.
The pulling string can be shortened by lowering the lower moving pulley B until the knob C rises and comes into close contact with the lower moving pulley B.

The Example of the drawstring operating device of this invention is shown, (a) is the front view which made the drawstring the longest, (b) is the front view which made the drawstring the shortest. The schematic diagram which showed the path | route of the drawstring which passes along the fixed pulley of the drawstring operating device of this invention, and a dynamic pulley. The front view which carried out the cross section of a part of Example of the drawstring operating device of this invention. The side view which carried out the cross section of a part of Example of the drawstring operating device of this invention. The sectional view which cut the rod part of the example of the drawstring operating device of the present invention.
