Description

[Detailed description of the invention] <Industrial field of application> This invention is a convenient fluorescent lamp blinking operation string that can be used when it is desired to adjust the length of the blinking operation string hanging from a fluorescent lamp. This relates to a winding tool.

<Prior Art> The length of this type of operating string may be desired to be long so that it can be operated even when lying down in bed, or may be desired to be short so that it does not touch the head when standing and walking. In order to make the length of the operating string variable, conventionally, a winding tool for the operating string was attached to the side of the fluorescent light, and the operating string was allowed to hang down by an appropriate length from the winding tool. things are on the market.

<Problem that the invention aims to solve> However, with the above-mentioned conventional product, it is necessary to reach out to the winding tool located at a high place, push the knob with one hand,
It was inconvenient that it could not be rolled out without pulling the string with the other hand.

The purpose of this invention is to be able to perform both feeding and winding with one hand, and to be small.
Moreover, it is an object of the present invention to provide a fluorescent lamp for a fluorescent lamp blinking operation string, which does not cause the winding to be interrupted or impossible due to being caught in the middle of winding.

<Means for solving the problem> In order to achieve the above-mentioned purpose, this invention allocates almost half of the width of the reel around which the string is wound to the mainspring loading part, and the remaining half is used for the narrow width part. In order to accommodate the locking and disconnecting device for stopping and rotating the reel, the locking and disconnecting device consists of a plurality of protrusions radially formed on one side of the plate-shaped ring part of the reel, and an operation button that is exposed at the center of the side of the case. It is composed of a non-rotatable single-letter-shaped operation plate that can be moved linearly by pushing the head of the rod, and a push spring that presses the operation plate.

By doing this, the flanged body of the reel can be narrow in width but tall, which not only allows the case to be made smaller, but also allows the string wound in a laminated manner to be made smaller. This eliminates the possibility of the winding being interrupted or impossible due to the winding hitting the inner surface of the case and getting stuck during the winding process.

<Example> This invention will be described below using an example shown in the drawings.

As shown in Fig. 1, there is a cylindrical case A in which left and right halves 1 and 2 are butted together and combined into one, and a small hole 5 made in the center of the circumference of the case A The hanging string 10 is pulled out,
Further, the head of the operating rod 11 is inserted into the half-split case 1 through the hole 6 formed in the center of the side surface of one half-split case 1.
It stands out almost flush with the side of the.

FIGS. 2 and 3 clearly show the parts incorporated in case A and their interrelationships.
Explaining in order below, several claws 3 and their locking grooves 4 are formed in the abutting portion of the half-split cases 1 and 2, and the claws 3 are forced into the locking grooves 4. They are designed to be easily joined by pushing them together. A cylindrical body 7 that communicates with the hole 6 is protruded from the inner surface of the half-split case 1, and the upper part of the cylindrical body 7 has a guide groove 8 in the longitudinal direction, and is fixed by inserting the inner end portion 14a of the mainspring 14. A locking groove 9 is formed. Inside the guide groove 8, there is a single-letter-shaped operation plate 12 provided in a direction perpendicular to the rear end of the operating rod 11 that is fitted inside the cylinder 7, and a push spring that presses the operating rod 11 toward a protrusion 17, which will be described later. 13 fits. The reel 15 around which the string 10 is wound has a central hole in the plate-like ring portion 15a of the reel 15 that is large enough to fit into the cylinder 7 so that it can rotate around the cylinder 7 of the half-split case 1. Open the 16th. Further, a plurality of (eight in the illustrated example) protrusions 17 are provided on one surface of the plate-shaped ring portion 15a to protrude in the radial direction.
Make it bigger than this. By doing this,
The manner in which the operating plate 12 engages and locks with the protrusion 17, and the manner in which the guide groove 12 moves along the inside of the operating rod 8 and engages with the protrusion 17.
It is now possible to obtain a mode of release that deviates from the above with a slight displacement.

Reel 1 integrally formed with plate-shaped ring portion 15a
A small hole 18 through which the end of the string 10 is inserted is formed in the flanged winding body 15b of No. 5 (see FIG. 3).
Tie a knot at the end of the string 10 passed through 8 and insert it into the small hole 1.
Attach it so that it does not fall out from 8. The string 10 is wound around the flanged body 15b by an appropriate length, and then passed through the small hole 5 of the half-split case 1 and taken out, as shown in FIG. The flanged winding body 15b has a plate-shaped ring portion 15 that does not have a protrusion 17 projecting thereon.
The mainspring 14 is placed in the space created by the other surface of the flange a and the lower surface of the flanged winding body 15b. Therefore, the winding trunk 15b has two slits 19, 1 into which the outer end portion 14b of the mainspring 14 can be inserted and locked.
9 is formed. Several hemispherical protuberances 20 are formed on both flange surfaces so as to reduce frictional resistance when the reel 15 rotates against the inner surfaces of the half-split cases 1 and 2.

To assemble, the reel 15 around which the string 10 passed through the small hole 5 is wound and the outer end portion 14b of the mainspring 14 is fixed is fitted into the cylindrical body 7 of the half-split case 1, and at the same time the inner part of the mainspring 14 is inserted. End portion 14a
is inserted into the locking groove 9, the operating rod 11 is fitted inside the cylinder body 7, the operating plate 12 and the push spring 13 are placed in the guide groove 8, and finally the other half case 2 is inserted.
If you press it and snap it into place, it will be assembled. FIG. 3 is a sectional view after assembly obtained in this way, in which the operating rod 11 is pressed against the protrusion 17 side by the push spring 13, and the operating plate 12 fitted in the guide groove 8 is pushed against the protrusion 17 of the reel 15. engage and lock,
The reel 15 is in a stationary state.

Now, the user pushes the head of the operating rod 11 against the force of the push spring 13, thereby disengaging the operating plate 12 from the protrusion 17, and in this state pulls the case A downward. For example, the string 10 can be reeled out by rotating the reel 15 against the force of the mainspring 14,
Conversely, if the case A is lifted upward while the string 10 is stretched, the reel 15 will rotate by the restoring force of the mainspring 14 and wind up the string 10. When you stop pushing the head of the operating rod 11, the push spring 13
The operation plate 12 engages and locks with the protrusion 17 again with the force of
As the reel 15 comes to rest, the winding and unwinding of the string 10 also stops immediately.

<Effects of the invention> As is clear from the above description, the height of the protrusions 17 radially protruding from the plate-shaped ring portion 15a, the height of the operation plate 12 that can be freely engaged with and disengaged from the protrusions 17, and the push spring 13. Since only a small height is required, even if the reel 15 is narrow, one side of the plate-shaped ring portion 15a can be used as a loading portion for the mainspring 14, and the other side can be used as a mounting portion for the locking and disengaging device. This is extremely effective in reducing the size of case A. Also, reel 1
Even if the width of the flanged winding body 15b of No. 5 is narrow, by making the height tall, it is possible to wrap a string 10 of sufficient length.
It is also possible to eliminate the inconvenience of the 0 hitting the inner surface of the case A and getting stuck during winding. Further, the operation can be carried out by pushing the operating rod 11 with one hand to raise and lower the case A, and the reel 15 rotates smoothly without kneading due to the action of the hemispherical protuberance 20.
