Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding a sheet-like material such as a light-shielding curtain for window shade and a tonneau cover for covering a cargo room of a vehicle.

[Problems to be solved by the prior art and invention] A sunshade is provided on windows, skylights, or sunroofs attached to structures such as vehicles, airplanes, and ships, houses, warehouses, etc. to prevent direct sunlight. It is often provided.

A tonneau cover device is used in a luggage compartment of a vehicle to prevent theft.

The sunshade and tonneau cover device is a sheet-like material winding device that winds and stores a sheet-like material such as a light-shielding curtain that covers a window and a tonneau cover that covers the upper part of a luggage compartment.

In such a sheet-like material winding device, the sheet-like material is generally wound around a winding drum and stored in a winding main body. At this time, the winding drum is normally urged by a torsion spring in the winding direction of the sheet. In this sheet-like material winding device, the winding body is appropriately attached to the vicinity of the window frame or the luggage compartment, and the sheet-like material is pulled out against the spring force of the torsion spring. The window or luggage compartment is covered with a sheet-like material by being locked to the side.

However, in the conventional sheet-like material winding device, since all of the operation of pulling out the sheet-like material from the winding body and locking the leading end of the drawn-out sheet-like material are performed manually, the operation is cumbersome, and the operation is particularly troublesome. The possibility of installation in places that are out of reach is small, and even if it is installed, its operability is much worse.

The present invention has been made in view of the above circumstances,
SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet-like material winding device in which a sheet-like material can be pulled out, stored, and maintained in a pulled-out state.

Means for Solving the Problems To achieve the above object, the present invention provides a winding body fixed to a fixing member for winding and storing a sheet-like material, and a long body fixed to a leading end of the sheet-like material. A left and right guide member positioned on both sides of the sheet-like object withdrawal direction and provided in the sheet-like object withdrawal direction; a left and right flexible rack member guided and guided by the guide member; A slider attached to a flexible rack member, both ends of which are pivotally supported, and one pinion with which the left and right flexible rack members mesh from both sides; The flexible rack members on both the left and right sides are synchronously converted into movements in different directions by a pinion to advance and retreat, and the sheet-like material is pulled out and pulled back.

In this case, the long member may have a multi-pipe structure in which both ends are stretchable.

[Operation] The sheet material is pulled out and stored by the flexible rack member which moves forward and backward by the rotation of the pinion, and the drawn state can be maintained by stopping the rotation of the pinion.

In the case where both ends of the long member fixed to the leading end of the sheet-like material have a multi-layer structure capable of expanding and contracting, a deformed window or a deformed load whose width dimension orthogonal to the drawing direction of the sheet-like material changes along the drawing direction. In the room, the length of the long material expands and contracts to change the length, so that it is possible to adapt to the change in the width dimension described above.

[Examples] Hereinafter, the present invention will be specifically described based on examples of sunshades.

FIG. 1 shows the main structure of a sunshade (sheet-like material winding device). The sunshade includes a winding body 1 and a light-shielding curtain (sheet-like material) wound and stored in the winding body 1.

The winding main body 1 has a winding drum 11 as shown in FIG.
And a torsion spring 12 that urges the winding drum 11 to rotate. The winding drum 11 is urged by the torsion spring 12 to rotate around the rotation shaft 13.

The light shielding curtain 2 is made of cloth or film. In particular, when the rear view cannot be obstructed for a vehicle, a meshable cloth, a cloth with many holes, or a transparent curtain of a translucent film is used. The light-shielding curtain 2 has a base end fixed to the winding drum 11, and is wound and stored on the winding drum 11 by rotation of the winding drum 11 by a torsion spring 12.

The elongate member 3 is made of a pipe material and has a double structure that can be extended and contracted at both ends. The elongate member 3 includes a pipe 31 and two rods 32 and 33 inserted into the pipe 31 slidably in the axial direction from both open ends of the pipe 31.
The long member 3 is attached to the light shielding curtain 2 by fixing the pipe 31 to the leading end of the light shielding curtain 2. rod
The diameters of the insertion ends 32a and 33a are so large that the insertion ends 32a and 33a are in sliding contact with the inner peripheral wall of the pipe 31, and are inserted through the caps 34 covering both ends of the pipe 31. The rods 32, 33 are guided by the insertion ends 32a, 33a and the through holes of the cap 34 so as to be slidable with respect to the pipe 31, and the sliding of the rods 32, 33 causes the elongate member 3 to move. It is stretchable. The outer end of the rods 32 and 33 at both ends of the long member 3 thus configured is connected to the guide member 4 respectively.
And 5.

As shown in FIG. 3, this linkage structure has a structure in which an outer end of a rod 33 is pivotally supported by a slider 9 slidably attached to the guide member 5. The rod 32 also has the same linkage structure.

As shown in FIG. 3 (a), the guide member 5 is formed of a long material having a square C-shaped cross section having a slit 51 on one side, and the slider 9 slides inside the hollow portion 52. It is supposed to. As shown in FIG. 3 (b), the slider 9 has a block portion 91, a locking piece 92 which stands vertically on one side surface of the block portion 91, and extends on both sides of the locking piece 92. Locking wings
93, and a locking piece 92 and a block portion 91 are inserted into the slit 51 and the hollow portion 52 of the guide member 5, respectively.
It is slidably attached to the guide member 5 so as to be sandwiched between the 91 and the locking wing 93. The slider 91 and the rod 33 are connected by pivotally supporting the outer end of the rod 33 and the locking piece 92 of the slider 9 with a pin 10.

The flexible rack member 7 is connected to the slider 9 as shown in FIG. 3 (b). In this case, a flexible rack member 6 is connected to a slider that slides inside the guide member 4.

As shown in FIG. 3, the flexible rack member 7 (6) is provided with teeth 72, 72,... Of equal pitch on one side surface of a long base material 71 having a rectangular cross section. It is integrally formed of a flexible material, and is easily bent along the shape of a window or the like (see FIG. 2).

These flexible rack members 6 and 7 are driven by a drive unit 8.

The drive section 8 is formed by incorporating a pinion 81 and a mechanism section 82 including a motor for rotating the pinion 81 into a casing 83 (see FIG. 4). As shown in FIG. 4, the flexible rack members 6, 7 are introduced into the drive unit 8 in parallel with the teeth 71 of the members 6, 7, and mesh with the pinion 81. In such a structure, when the pinion 81 is rotated in the direction A by the driving of the mechanism section 82, the flexible rack members 6 and 7 move in the directions C and E, respectively, and the light shielding curtain 2 in the stretched state shown in FIG. Is pulled down via the long member 3, and the light shielding curtain 2 is stored in the winding main body 1. A mentioned above
When the pinion 81 is rotated in the direction B opposite to the direction, the flexible rack members 6 and 7 move in the directions D and F, respectively, and pull out the light shielding curtain 2 in the stored state via the long member 3. The window can be shielded by the light shielding curtain 2. When the window is partially covered with the light shielding curtain 2, the rotation of the pinion 81 is stopped to stop the movement of the flexible rack members 6 and 7, and
This can be easily performed by holding the long member 3 at an appropriate halfway position (see FIG. 2).

Next, a case where the sunshade configured as described above is applied to a rear window 200 of an automobile will be described.

In this case, as shown in FIG. 5, the winding body 1 and the drive unit 8 are fixed below the rear parcel 201, and the guide member
Reference numerals 4 and 5 are fixed in slide grooves 202 provided in both pillars. At this time, the rear parcel 201 is provided with an opening 203 for drawing out the light-shielding curtain 2. When the light-shielding curtain 2 is housed, the long member 3 has the rods 32 and 33 on both sides thereof, as shown in FIG. It is in contact with the upper surface of the rear parcel 201 on both sides of the 203. Then, the mechanism section 82 of the drive section 8
Is connected to an operation mechanism (not shown) in the driver's seat, and can be turned ON / OFF by an operation in the driver's seat.

When the pinion 81 of the drive unit 8 rotates and the flexible rack members 6 and 7 are extended, the sliders 9 and 9 fixed to the tips of the rack members 6 and 7 are moved inside the guide members 4 and 5. And the long member 3 pivotally supported on both sides by the sliders 9, 9 is pulled up. The pulling of the long member 3 is performed until it approaches the ceiling 204, and thereafter, the rotation of the pinion 81 is stopped to thereby stop the rear window as shown in FIG.
200 can be covered with the light shielding curtain 2. In this light-shielding state, the light-shielding curtain 2 is stretched without looseness by the action of the urging force of the torsion spring 12 of the winding body 1 in the winding direction.

Further, in order to release the light-shielding state, the rotation of the pinion 81 of the drive unit 8 is rotated in the opposite direction to that described above, and the flexible rack members 6, 7 that have been drawn out may be pulled back. The length member 3 is pulled down, and the light-shielding curtain 2 is wound around the winding body 1 by the spring force of the torsion spring 12 and stored.

As described above, the window width changes in the process of pulling out and storing the light shielding curtain 2, but the amount of change in the window width is absorbed by the sliding length of the rods 32, 33 sliding on the pipe 31. The slider 9 connected to the outer ends of the rods 32 and 33 can slide smoothly inside the guide members 4 and 5.

In the case where the rear window 200 is partially shielded, the rotation of the pinion 81 is appropriately stopped in the process of pulling out and storing the light shielding curtain 2, and the movement of the long member 3 is stopped at an intermediate position. good.

FIG. 6 shows an example of a change in the installation location of the drive unit 8. In this embodiment, the only difference is that the drive unit 8 is installed above the upper frame 104 of the window 100, unlike the embodiment of FIG. And other structures are the same. In this case, the long member 3 is pulled down by extending the flexible rack members 6 and 7, and the long member 3 is pulled up by pulling back.

 FIG. 7 shows another embodiment of the flexible rack member.

This flexible rack member 7 'has a coil 7'
It is formed by closely winding 2 'at an equal pitch. In the flexible rack member 7 ′, the coil 72 ′ corresponds to the teeth 72 of the flexible rack member 7 described above, and like the flexible rack member 7, meshes with the pinion 81 of the drive unit 8 to form the pinion 81. Move forward and backward by rotation.

As another variation, the guide member is not limited to the above-described square C-shaped cross section, but may be a round C-shaped cross section or a cross section having a polygonal shape such as a triangle, and the drive unit is not limited to electric drive and may be manually operated. May be.

Further, all of the above-described embodiments have described the sunshade, but the present invention can be similarly applied to a tonneau cover device.

[Effects of the Invention] As described above, according to the present invention, it is possible to pull out and store a sheet-like object by rotating one pinion, and to maintain the drawn-out state of the sheet-like object by stopping the rotation of the pinion. In addition, there is no need to grasp and pull out the leading end of the sheet-like object by hand, and it is not necessary to perform an operation of hanging the leading end of the sheet by hand, so that the operation is simplified and the driving unit (pinion) is installed close to the operation. Or the drive unit is electrically operated to enable remote control.

In particular, since the flexible rack members on the left and right sides are synchronously converted into movements in different directions by one pinion, and the sheet-like object is pulled out and pulled back, the sheet-like object can be smoothly moved without prying or the like. Can be pulled out and stored.

In addition, since the operating member that moves forward and backward by the drive unit is not a simple string but a flexible rack member, the operational reliability is improved.
