Description

  The present invention relates to a vehicular blind device that blocks out sunlight entering a passenger compartment from windows provided on left and right doors of a vehicle to create a shade.

Some vehicle blind devices correspond to a window in which a substantially triangular window is connected to a substantially square window. The rectangular window blind sheet is stored almost horizontally, and the triangular window blind sheet is stored almost vertically.
This device is electrically driven and when the switch is pressed, the blind seat for the square window is pushed upward and closed. It is possible to reduce loss due to friction when the blind window for the triangular window is pushed and closed to the rear of the vehicle with the same drive source (see, for example, Patent Document 1).

Moreover, there exists a thing which closes the blind sheet for triangular windows with a dedicated electric drive device (for example, refer patent document 2).
Furthermore, by connecting members such as the winding shaft of the blind sheet (shade sheet) for square windows and the winding shaft of the blind sheet (shade sheet) for triangular windows to the T-shaped central member, the size of the device can be reduced. There is what was planned (see, for example, Patent Document 3).

However, in the prior art (Patent Documents 1, 2, and 3), the triangular window blind sheet (shade sheet) is directed from one edge of the triangular window toward the rear of the vehicle toward the other edge of the triangular window or an acute angle. Even if the blind sheet is closed, light enters between the other edge that the blind sheet cannot handle and the blind sheet, that is, from where there is no blind sheet.
It is hoped that the blind sheet is improved in light-shielding properties by associating the blind sheet with a triangular window, for example, a window whose corners extend rearward of the vehicle and the other edge is inclined rearward of the vehicle as described in Patent Document 2. It was rare.

An output shaft 94 is provided at the sheet guide end 107.
The end of the first blind sheet 16 is attached to the roll core body 106.

In such a first winding mechanism 41, when the first blind sheet 16 is pulled, the roll core body 106 and the spring latching portion 108 rotate, so that the spring 98 is twisted and the first blind sheet 16 is Apply tensile force.
As shown in FIGS. 1 and 4, a second winding mechanism 55 is connected to the first winding mechanism 41 via a linear motion mechanism 73.

  The second take-up mechanism 55 is substantially the same as the first take-up mechanism 41 in that a tension force is applied to the second blind sheet 17 by the spring 111.

Specifically, the second blind sheet 17 and the winding shaft (winding roll core) to which the ends of the second blind sheet 17 are attached correspond to the rotation and inclination (angle α) of the arm 46. The winding shaft (winding roll core) is slightly conical, and the second blind sheet 17 is slightly fan-shaped.
The pulling end portion 68 of the second blind sheet 17 is connected to the linear motion mechanism 73 by the arm 46.

  The arm 46 is movably connected to the side portion 114 of the first rack 71 and the side portion 115 of the second rack 72 by a connecting pin 116 (in the direction of arrow a1).

  The arm 46 coincides with the inclination (angle α) of the rear vertical sash 58 when the second blind seat 17 is closed (advance limit position E) when viewed from the side of the vehicle 11 (viewpoint in FIG. 4). Just tilted. Sp is the origin position of the arm 46.

Next, the operation of the vehicle blind device according to the first embodiment will be described.
First, a mechanism for improving the light shielding property will be described (see FIGS. 1 and 2).

In the vehicular blind device, when the first blind sheet 16 is pulled and closed as indicated by an arrow a2, the second blind sheet 17 is automatically pulled and closed as indicated by an arrow a3.
The closed second blind seat 17 reaches the rear vertical sash portion 58 of the sash frame 27 inclined rearward of the vehicle 11, so that the sunlight from between the rear vertical sash portion 58 and the second blind seat 17, etc. Most of the light does not enter. Therefore, the light shielding property is enhanced.

  Next, a mechanism in which the second blind sheet 17 is automatically pulled to the inclined rear vertical sash portion 58 will be described (see FIGS. 1 to 9).

When the passenger sitting on the rear seat 22 pulls the first blind seat 16 by hand as indicated by arrow a2, the winding shaft (winding roll core) 67 rotates as indicated by arrow a4 (FIG. 9). The input helical gear 86 that is integrally fitted to the core 67 rotates (in the direction of arrow a4).
This input is such that the driven first helical gear 87 meshing with the helical gear 86 rotates (in the direction of arrow a5 in FIG. 6), and the driven second helical gear 88 rotates at the same time (in the direction of arrow a6 in FIG. 6). To do.

  Since the first pinion 75 rotates (in the direction of arrow a5) by the rotation of the first shaft 91 integrally fitted with the driven first helical gear 87, the first pinion 75 moves the first rack 71. The vehicle 11 is slid forward by a distance S1 toward the rear of the vehicle 11.

  On the other hand, the second pinion 76 is rotated (in the direction of arrow a6 in FIG. 6) by the rotation of the second shaft 92 that is integrally fitted to the driven second helical gear 88, so that the second pinion 76 is The second rack 72 is slid forward by a distance S2 toward the rear of the vehicle 11. The movement from the origin position Sp is referred to as advance. Conversely, moving toward the origin position Sp is defined as a backward movement. The direction in which the vehicle moves forward or backward does not match.

  When the first rack 71 and the second rack 72 slide forward, the arm 46 connected thereto moves from the origin position Sp to the rear vertical sash portion 58 (forward limit position E).

In this process, when the first rack 71 slides forward by a distance S1 and the second rack 72 slides forward by a distance S2, the arm 46 and the pulling end portion 68 of the second blind seat 17 are moved. Since it inclines so as to fall backward as indicated by an arrow a7 (angle α), it reaches the rear vertical sash 58 and coincides with the angle of the rear vertical sash 58.
The distance S1 is set by the pitch circle diameter (diameter) d1 of the first pinion 75, and the distance S2 is set by the pitch circle diameter (diameter) d2 of the second pinion 76.

Note that when the first blind sheet 16 is pulled as indicated by an arrow a2, the spring 98 is twisted, so that tension is continuously applied to the first blind sheet 16.
Similarly, since the spring 111 continues to apply tension to the second blind sheet 17, sagging of the second blind sheet 17 can be suppressed.

Next, a mechanism for opening the blind sheet 13 (the first blind sheet 16 and the second blind sheet 17) will be described.
When opening the first blind sheet 16, if the upper frame 31 of the first blind sheet 16 is removed from the hook 28, the first blind sheet 16 rotates reversely by the force of the spring 98 (winding roll core). 67 is automatically wound up.

When the winding shaft (winding roll core) 67 rotates in the reverse direction, the driven first helical gear 87 and the driven second helical gear 88 rotate in the reverse direction, so that the first rack 71 and the second rack 72 are rotated. Slide backwards. As a result, the arm 46 and the pulling end portion 68 of the second blind seat 17 retreat toward the front of the vehicle 11 (to the origin position Sp).
That is, when the first blind sheet 16 is opened, the second blind sheet 17 is opened almost simultaneously.

  As described above, in the vehicular blind device, even if the rear vertical sash portion 58 of the rear door 12 is tilted to the rear of the vehicle 11 (desired angle α) and formed in an inclined shape, the first blind seat 16 is closed. With the simple structure linked to the light shielding property of the blind sheet 13, specifically, the second blind sheet 17 can be improved.
