Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding device for sheet-like materials such as window shade curtains and tonneau covers that cover the luggage compartment of vehicles.

[Prior art and problems to be solved by the invention] Vehicle structures such as vehicles, airplanes, ships, etc., and houses.

Sunshades are often installed on windows, skylights, or sunroofs attached to buildings such as warehouses to avoid direct sunlight.

Additionally, a tonneau cover device is used in the luggage compartment of a vehicle to prevent theft.

These sunshade and tonneau cover devices are sheet-like object winding devices that wind and store sheet-like objects such as light-shielding curtains that cover windows and tonneau covers that cover the upper part of luggage compartments.

In such a sheet-like material winding device, the sheet-like material is generally wound around a winding drum and stored in a winding body. At this time, the winding drum is normally biased in the winding direction of the sheet-like material by a torsion spring. In this sheet-like material winding device, the winding body is appropriately attached to the window frame or the vicinity of the luggage compartment, and the sheet-like material is pulled out against the spring force of the torsion spring, and the tip of the sheet is placed opposite the winding body. By locking it on the side, a sheet-like material is used to cover the trunk or luggage compartment.

However, in conventional sheet-like material winding devices, the operations of pulling out the sheet-like material from the winding main body and locking the leading end of the drawn-out sheet-like material are all performed manually, making the operation cumbersome and especially There is little possibility that it will be installed in a place that is out of reach, and even if it were installed, its operability would be much worse.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a sheet-like material winding device that enables remote control of drawing out, storing, and maintaining the drawn-out state of the sheet-like material. .

Means for Solving the Problem] In order to achieve the above object, the present invention provides a winding body fixed to a fixing member for winding and storing a sheet-like object, and a long winding body fixed to a drawer end of the sheet-like object. A member, a slider pivotally supported at both ends of the elongated member and slidably attached to a guide member, and a flexible rack member connected to the slider and linearly moved by rotation of a pinion. It is characterized by what it does.

In this case, the elongated member may have a multi-vib structure in which both ends are expandable and retractable.

[Function] The sheet-like object is pulled out and stored by a flexible rack member that moves linearly with the rotation of the pinion, and the pulled out state can be maintained by stopping the rotation of the pinion.

If both ends of the elongated member fixed to the tip of the sheet-like object are made to have a stretchable multilayer structure, a deformable window or a deformable load whose width dimension perpendicular to the sheet-like object's drawing direction changes along the drawing direction. Even in the chamber, the elongated material expands and contracts to change its length, thereby adapting to the above-mentioned change in width dimension.

The elongated member 3 can be expanded and contracted by sliding at an angle of 33 degrees. In the elongated member 3 configured in this manner, the outer ends of the rods 32 and 33 at both ends thereof are linked to the guide members 4 and 5, respectively.

As shown in FIG. 3, this linking structure is such that the outer end of the rod 33 is pivotally supported by a slider 9 that is slidably attached to the guide member 5.

Note that the rod 32 side also has the same interlocking structure.

As shown in FIG. 3(a), the guide member 5 is made of a long material having a rectangular C-shaped cross section with a slit 51 on one side, and the slider 9 slides inside the hollow part 52. It is supposed to be done. As shown in FIG. 3(b), the slider 9 includes a block portion 91, a locking piece 92 vertically provided on one side of the block portion 91, and a locking piece 92 extending on both sides of the locking piece 92. The locking piece 92 and the block part 91 are inserted into the slit 51 and the hollow part 52 of the guide member 5, respectively, and the wall forming the slit 51 of the guide member 5 is inserted into the block part 91. It is slidably attached to the guide member 5 so as to be sandwiched between the locking wings 93. The slider 91 and the rod 33 are connected by pivoting the outer end of the rod 33 and the locking piece 92 of the slider 9 with the pin 10.

A 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 the slider that slides within the guide member 4.

As shown in FIG. 3, the flexible rack member 7 (6) has teeth 72.72.72.
... is provided, and is integrally formed from a flexible material such as synthetic resin, making it easy to bend to fit the shape of a window, etc. (see Figure 2).

These flexible rack members 6 , 7 are adapted to be 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). Then, the flexible rack members 6.7 are connected to each member 6.7 as shown in FIG.
are introduced into the drive unit 8 in parallel with the teeth 71 opposing each other, and mesh with the pinion 81. In such a structure, when the pinion 81 is rotated in six directions by driving the mechanism part 82, the flexible rack members 6 and 7 move in directions C and E, respectively, and the light shielding curtain 2 in the tensioned state shown in FIG. is pulled down via the elongated member 3, and the light-shielding curtain 2 is stored in the winding body 1.

In addition, when partially covering the window with the light shielding curtain 2, the rotation of the pinion 81 is stopped, the movement of the flexible rack members 6 and 7 is stopped, and the elongated member 3 is held at an appropriate midway position. Easy to do (Second
(see figure).

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

In this case, as shown in FIG. 5, the winding body 1.degree. and the drive section 8 are fixed below the rear parcel 201, and the guide members 4.5 are fixed in slide grooves 202 provided in the pillars on both sides. At this time, the capacitor 201 has a light-shielding curtain 2.
A drawer opening 203 is provided, and when the light shielding curtain 2 is stored, the elongated member 3 has both rods 32 and 33 on the top surface of the rear bar cell 201 on both sides of the opening 203, as shown in FIG. 5(a). They are in contact with each other. The mechanism section 82 of the drive section 8 is connected to an operating mechanism (not shown) in the driver's seat, and can be turned on or off by operation from the driver's seat.
It is now possible to F.

When the pinion 81 of the drive unit 8 rotates and the flexible rack member 6.7 is paid out, the sliders 9, 9 fixed to the tips of the respective rack members 6.7 move to the guide member 4.5. At the same time, the elongated member 3, which is pivotally supported on both sides by the slider 9.9, is pulled up. This elongated member 3 is pulled up until it approaches the ceiling 204, and then the pinion 8
By stopping the rotation of the rear window 200, the rear window 200 can be covered with the light-shielding curtain 2 as shown in FIG. 5(b). In this light-shielding state, the light-shielding curtain 2 is stretched without loosening due to the force exerted in the winding direction of the torsion spring 12 of the winding main body l.

In addition, in order to release the light shielding state, the pinion 81 of the drive unit 8 may be rotated in the opposite direction to the above-mentioned direction to pull back the flexible rack member 6.7.
As a result, the elongated member 3 is pulled down, and the light-shielding curtain 2 is wound up and stored in the winding body 1 by the spring force of the torsion spring 12.

In this way, the inside of the window changes during the process of drawing out and storing the light shielding curtain 2, but the amount of change inside the window is absorbed by the sliding length of the rods 32 and 33 that slide against the vibrator 31. The sliders 9 connected to the outer ends of the rods 32, 33 can slide smoothly within the guide members 4, 5.

In addition, when the rear window 200 is partially shaded, the rotation of the pinion 81 is appropriately stopped during the process of drawing out and storing the shade curtain 2 described above, and the movement of the elongated 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 drive unit 8 is installed above the upper frame of the window 100 ]04, which is different from the embodiment shown in FIG. The other structures are the same. In this case, the elongated member 3 will be pulled down by feeding out the flexible rack member 6.7, and the elongated member 3 will be pulled up by pulling it back.

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

This flexible rack member 7' has a coil 7 attached to the cable 71'.
2' closely wound at equal pitches. In this flexible rack member 7', the coil 72' corresponds to the teeth 72 of the flexible rack member 7 described above, and similarly to the flexible rack member 7, the coil 72' meshes with the pinion 81 of the drive section 8, so that the pinion 81 Rotation causes linear motion.

In addition, as another variation, the guide member is not limited to the square C-shaped cross section described above, but may have a round C-shaped cross section or a polygonal shape such as a triangle with a slit, and the drive unit is not limited to electric, but may be manual. It's okay.

Furthermore, although all of the above embodiments have been described with respect to sunshades, they can be similarly applied to tonneau cover devices.

[Effects of the Invention] As described above, according to the present invention, by rotating the pinion, it is possible to draw out and store the sheet-like object, and by stopping the rotation of the pinion, the sheet-like object can be maintained in the bowed state. There is no need to grasp the tip of the sheet-like material by hand to pull it out, and there is no need to pull the tip of the drawer by hand, making the operation simpler and easier to operate. Remote control is possible by electrically driving the drive unit.

Furthermore, since the operating member that is linearly moved by the drive section is a flexible rack member rather than a simple string, operational reliability is improved.
