It can be suspended by putting it in 1 g.

<Detailed Description of Structure> FIGS. 4 to 9 are for explaining the details of the structure of the sheet expanding / contracting / storing device and the sheet winding / unwinding mechanism used in the device.
FIG. 4 is a perspective view of the sheet unfolding / folding storage device, FIG. 5 is a side view showing a part of the sheet unfolding / folding storage device, and FIG. 7 is an enlarged perspective view showing a winding force applying mechanism for applying a winding force, FIG. 8 is a side view showing an enlarged high-speed winding preventing device, and FIG. 9 is an enlarged view of a lock device. FIG.

In these figures, the housing 12 is constructed as follows. That is, as shown in FIGS. 4 and 5, the roll 21 is rotatably disposed inside the housing 12 via the fixing piece 22 extending from the side surface of the housing 12.

A large diameter portion 16 is provided at the end of the central sheet 11a of the sheet 11, and a string 17 is provided at the large diameter portion 16.

As shown in FIG. 6, the roll 21 is provided with a winding start stopper 24 for the sheet base 11p, and the sheet base 11p is fixed to the winding start stopper 24. Further, at both ends of the roll 21, sheet winding prevention rings 25, 25 are provided, respectively.

Although not shown in FIGS. 4 and 5, a winding force applying mechanism is attached to the end of the roll 21 to apply the sheet base 11 p and the sheet 11 to the roll 21. Power is given.

Although not shown in FIGS. 4 and 5, the roll 21 is provided with a high-speed take-up prevention mechanism and a lock mechanism.
The p and the sheet 11 are prevented from being wound up at a high speed, and the sheet 11 fed out by the lock mechanism can be locked at that position.

The winding force applying mechanism 27 includes a leaf spring coil 29, a center bearing 31, a bearing shaft 33, a ring case 35, and a lid 37, as shown in FIG. That is,
The winding start portion on the center side of the leaf spring coil 29 is the center bearing 31.
And the bearing shaft 33 to the center bearing 31 and the bearing shaft 33. The outer winding end portion of the leaf spring coil 29 is fixed to a fixing portion 39 of the ring case 35. The leaf spring coil 29 is taken up when the sheet 11 is fed out, and the restoring force of the leaf spring coil 29 applies an urging force to wind the sheet 11 to the roll 21.

As shown in FIG. 8, the high-speed take-up prevention mechanism 41 includes an interlocking pulley 43 interlocked with the rotation shaft of the roll 21.
It comprises a rotating shaft moving roller 45 and a fixed roller 47 which does not rotate. The interlocking pulley 43 rotates in conjunction with the rotation axis of the roll 21. A rotating shaft moving roller 45 comes into contact with the interlocking pulley 43. The rotating shaft moving roller 45 has a shaft movable in the directions indicated by arrows X and Y. When the interlocking pulley 43 rotates at a high speed, the shaft of the rotating shaft moving roller 45 moves in the direction indicated by arrow X to move the rotating shaft. The roller 45 enters between the interlocked pulley 43 and the fixed roller 47 to prevent the interlocked pulley 43 from rotating at high speed. Also, sheet 1
1 is being fed, the rotating shaft moving roller 45
The pulley 43 is configured to move in the direction so as not to hinder the rotation of the interlocking pulley 43.

As shown in FIG. 9, the lock mechanism 51 includes a roll 21 that winds or unwinds the sheet base 11p and the sheet 11, a free rubber pulley 53 that contacts or separates from the roll 21, a roller 55, and a rubber pulley. And an operation mechanism for preventing the roller 53 from contacting the roll 21. This free rubber pulley 53 can be stopped and released from the outside. This rubber pulley 53
Is free when the roll 21 rotates in the feeding direction of the sheet 11 and does not hinder the rotation of the roll 21, but when the roll 21 rotates in the winding direction of the sheet 11, the gap between the roll 21 and the roller 55 The rotation of the entering roll 21 is stopped. In order to rotate the roll 21, the rubber pulley 53
Is provided with a mechanism that separates from the roll 21.

How to use such a sheet expanding / contracting storage device will be described.

<When Used as a Curtain> First, the string 17 of the sheet 11 of the sheet expanding / contracting storage device 1 is held, and the string 17 is pulled. Then, the roll 21 rotates and the sheet 11 is fed out. At this time, the leaf spring coil 2
9 rotates. Therefore, the leaf spring coil 29 is wound according to the amount of feeding.

In the high-speed take-up prevention mechanism 41, since the rotating shaft moving roller 45 does not hinder the rotation of the interlocking pulley 43 by moving in the direction of the arrow Y, the roll 21 rotates freely.

Further, when the roll 21 is rotating in the direction in which the sheet 11 is fed out, the rubber pulley 53 is free and does not hinder the rotation of the roll 21, but the roll 21 rotates in the winding direction. Sometimes, it is interposed between the roll 21 and the roller 55 to prevent the roll 21 from rotating.

When the pulling of the sheet 11 is stopped, the roll 21 tries to rotate in the winding direction by the winding force applying mechanism 27, but the rubber pulley 53 enters between the roll 21 and the roller 55 so that the roll 21 is rotated. Is prevented from rotating, and the sheet 11 is not drawn into the housing 15.

Then, the string 17 of the sheet 11 is pulled until it cannot be further extended.

Next, the right end side sheet 11c is peeled off from the left end side sheet b and developed, and the engaging hole 11g is hooked on the mounting portion 13a of the sheet hanging bracket 13.

Next, the left end sheet 11b is moved to the center sheet a.
Then, the sheet is unfolded and deployed, and the engaging hole 11g is hooked on the mounting portion 13a of the sheet hanging bracket 13.

Thus, the sheet expanding / contracting storage device can be used as a curtain as shown in FIG.

<Description when not used as a curtain>
First, the engaging hole 11g of the left end sheet 11b is detached from the mounting portion 13a of the sheet hanging bracket 13, and the magic tape 11d of the left end sheet 11b and the magic tape 11d of the center sheet 11a are bonded.

Next, the engagement hole 11g of the right end sheet 11c is formed.
Is removed from the mounting portion 13a of the sheet hanging bracket 13, and the magic tape 11e of the right end sheet 11c and the magic tape 11e of the right end sheet 11b are adhered.

By strongly pulling the sheet 11 by holding the string 17 of the sheet 11, the rubber pulley 53 of the lock mechanism 51 of the sheet expanding / contracting storage device 1 is prevented from coming into contact with the roll 21 by a mechanism not shown. Is operated. When the cord 17 of the sheet 11 is released from the hand, the roll 21 rotates in the winding direction by the urging force of the leaf spring coil 29 of the winding force applying mechanism 27. At this time, the rotating shaft moving roller 45 of the high-speed winding prevention mechanism 41 moves in the X direction shown
To reduce the rotational force of the interlocking pulley 43 interlocking with the rotation of the roll 21.

Accordingly, the sheet 11 is wound around the roll 21 with a slow rotational force. Finally, the sheet 11 is entirely stored in the storage housing 15 and only the large diameter portion 16 is exposed from the storage housing 15.

In the above embodiment, the central sheet 1
Although the description has been given of the case where the end sheets 11b and 11c are provided on both sides with respect to 1a, the form may be such that the sheet 11b or the sheet 11c is provided on only one side.

Therefore, according to the sheet expanding / contracting storage device 1, there are the following advantages. (1) It can be used as a window curtain having a width twice or three times the width of the central sheet 11a. (2) Since the sheet 11 is detachable from the sheet base 11p by the sheet removal button 11q, there is an advantage that the sheet 11 can be washed immediately or even when the sheet 11 is replaced.

In the first embodiment, the sheet hanging bracket 13 is fixed at a predetermined position as shown in FIG. 3. However, as shown in FIG.
The hanger 132 may be provided on the annular body 131 engaged with the thirty.
