  By the way, when it is set as the structure which covers the whole side window collectively with a single shade from a viewpoint of reducing a number of parts, it has to arrange | position a shade to the vehicle interior side rather than a division bar. However, since the slider portion includes a support portion that supports the frame so as to be movable in the front-rear direction, the division bar increases in size and approaches the vehicle interior side. In addition, if the shade is arranged on the interior side of the division bar, the interior space of the vehicle is greatly reduced.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to downsize a division bar and cover a side window with a single shade.

  The present invention is a sunshade device that shields a side window of a vehicle door, a division bar that partitions the side window in the vehicle front-rear direction, a single shade that collectively covers the side window, and an upper end of the shade. Provided with a frame that pulls out the shade, a support part that supports the frame so as to be movable in the longitudinal direction of the vehicle, and a slider part that is supported so as to be movable in the vertical direction inside the division bar. The frame is arranged outside the division bar by extending from the slider part to the vehicle front side, and the frame is characterized in that it is arranged offset to the vehicle interior side with respect to the slider part.

  According to such a configuration, since the support portion is arranged outside the division bar, the cross section of the guide groove for guiding the slider portion of the support portion provided in the division bar to be movable can be reduced, and the division bar itself can be reduced as a whole. The size can be reduced, and even if the shade is arranged on the side of the compartment of the division bar, the space in the compartment is not narrowed. That is, since the side windows can be collectively covered with a single shade, only one frame is required to pull out the shade, and only one drive mechanism is required to drive this frame in the vertical direction. For this reason, the number of parts can be reduced, the part cost can be reduced, and the entire apparatus can be configured simply.

The following configuration is preferable as an embodiment of the present invention.
The support portion supports one end portion of the frame, and the other end portion of the frame is supported so as to be movable in the vertical direction and the vehicle front-rear direction by a counter frame portion that is disposed to face the division bar in the vehicle door. It is good also as a structure.
According to such a configuration, both end portions of the frame can be supported so as to be movable in the vertical direction and the vehicle longitudinal direction, so that the frame can be supported in a stable posture.

The support portion may have a long hole that is long in the front-rear direction, and the frame may have a support pin that is accommodated in the long hole.
According to such a configuration, the frame can be supported so as to be movable in the vehicle front-rear direction with respect to the support portion with a simple configuration of a long hole and a support pin.

  According to the present invention, the division bar can be downsized and the side window can be covered with a single shade.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 1, the vehicle door of the present embodiment includes a door panel 10 having a window frame 11, a side window 20 disposed in the window frame 11, and a sunshade device 30 that shields the side window 20. Configured. Further, the window frame 11 has a division bar 12 extending in the vertical direction, and the side window 20 is partitioned in the vehicle front-rear direction by the division bar 12. Further, the window frame 11 has a front frame portion (an example of the “opposing frame portion” of the present invention) 13 that is disposed to face the front side of the division bar 12.

  In the following description, the vehicle front-rear direction refers to the left-right direction (left side) as the vehicle front side (vehicle front) and the right side (right) as the vehicle rear side (vehicle rear) with reference to the left-right direction in FIG. 1 is based on the vertical direction in FIG. 1, and the vehicle width direction is based on a direction perpendicular to the paper surface in FIG. In the following description, the vehicle front side (vehicle front) is abbreviated as front side (front), and the vehicle rear side (vehicle rear) is abbreviated as rear side (rear).

  The side window 20 is composed of a front window 21 and a rear window 22 arranged on both front and rear sides with the division bar 12 in between. The front window 21 has a substantially rectangular shape and can be driven in the vertical direction by a driving means (not shown). The front end side of the front window 21 is longer than the rear end side. On the other hand, the rear window 22 has a substantially triangular shape, and is a fixed window called a so-called triangular window. The rear window 22 is a fitting type window and is fixed so as not to be opened and closed.

  The sunshade device 30 drives a frame 31 that is a sheet-shaped curtain, a frame 32 that is integrally attached to the upper end of the shade 31 between the front frame 13 and the division bar 12, and the frame 32 in the vertical direction. A drive mechanism and the like are provided. This drive mechanism includes a motor M, a pair of wires W driven by the motor M, a pair of slider portions S (see FIG. 5) fixed to the tip portions of the wires W, the division bar 12 and the inside of the front frame portion 13. The guide grooves 12A and 13A (see FIG. 4) formed in The movement in the vertical direction of both slider portions S is guided by both guide grooves 12A, 13A.

  When the motor M rotates, a gear (not shown) fixed to the rotating shaft of the motor M rotates, and this gear is inserted into a groove C (see FIG. 5) formed in a spiral shape on the outer peripheral surface of the wire W. The wire W can be advanced and retracted by meshing. In the present embodiment, two types of gears having different numbers of gears are fixed to the rotation shaft of the motor M, and a gear having a large number of gears corresponds to the front side frame portion 13. This is because the feed amount of the wire W that moves in the guide groove 13A of the front frame portion 13 due to the fact that the front frame portion 13 is longer than the division bar 12, the wire W that moves in the guide groove 12A of the division bar 12 This is to make it larger than the feed amount.

  Here, the winding device that winds up the shade 31 will be briefly described with reference to FIG. 2. The winding device can wind the winding shaft (not shown) that winds up the shade 31 and the winding shaft. A case 33 for supporting and winding the shade 31 and a biasing member (not shown) for constantly biasing the winding shaft in the winding direction are configured.

  As described above, since the front frame portion 13 is longer than the division bar 12, it is necessary to form the shade 31 longer on the front end side than on the rear end side, and the shade 31 is wound by a single winding shaft. Therefore, the shade 31 has a substantially truncated cone shape in the wound state. Therefore, as shown in FIG. 3, the frame 32 drawn upward from the winding device has a front end portion and a rear end portion each having an arc-shaped locus.

  On the other hand, since the front frame portion 13 and the division bar 12 are formed in a substantially straight line shape, the trajectory through which both slider portions S guided by the guide grooves 12A and 13A pass is also a straight line. As a result, a deviation occurs in the front-rear direction between the trajectory drawn by the front and rear end portions of the frame 32 and the trajectory through which both slider portions S pass. Therefore, in the present embodiment, a pair of support portions H that support the front and rear end portions of the frame 32 so as to be movable in the front-rear direction are provided as measures for absorbing this shift. In the following description of the structure of the support portion H and the slider portion S, only the support portion H and the slider portion S arranged on the rear side will be described when the description overlaps.

  The support part H is provided integrally with the slider part S as shown in FIG. Although the support portion H has a form that protrudes laterally from the slider portion S, the connection portion with the frame 32 is disposed offset to the vehicle interior side. This connecting portion has a long hole H1 that is long in the front-rear direction, and a support pin 34 that protrudes from the frame 32 is accommodated inside the long hole H1. The support pin 34 has a substantially cylindrical shape, and a screw 35 is attached to the support pin 34 to prevent the support portion H from coming off. The support pins 34 are made of synthetic resin and are formed integrally with the frame 32.

  Thereby, the support pin 34 is supported so that the inside of the long hole H1 can move to the front-back direction. Accordingly, the frame 32 includes a shielding position (position indicated by a two-dot chain line) P1, an intermediate position (position indicated by a one-dot chain line) P2, and an open position (position indicated by a solid line) P3 of the frame 32 shown in FIG. It is possible to guide the frame 32 in the vertical direction by both the slider portions S while absorbing the positional deviation between the front and rear end portions and the both slider portions S.

  By the way, in this embodiment, as shown in FIG. 4, the slider portion S is disposed inside the guide groove 12 </ b> A of the division bar 12, but the support portion H extends from the slider portion S to the front side. It is arranged outside the bar 12. In this case, the division bar 12 can be reduced in size because the cross-sectional area of the guide groove 12A can be made smaller than when both the slider portion S and the support portion H are accommodated in the guide groove 12A. Thus, the amount of the 12 protruding toward the vehicle interior side can be reduced. For this reason, even if it installs the shade 31 in the vehicle interior side of the division bar 12, it does not narrow a vehicle interior space.

  Therefore, in the present embodiment, when the shade 31 is installed on the interior side of the division bar 12, the support portion H is offset from the slider portion S toward the interior of the vehicle interior, and the frame 32 is attached to the support portion H. It is connected to the passenger compartment side. As a result, the shade 31 is prevented from interfering with the division bar 12, the housing and unfolding operation of the shade 31 is smooth, and the shade 31 is arranged on the vehicle interior side of the division bar 12 without narrowing the vehicle interior space. be able to. Therefore, the shade 31 can be configured by a single shade that collectively covers the front window 21 and the rear window 22. This eliminates the need for parts such as the shade dedicated to the rear window 22, the winding device dedicated to the rear window 22, and the wire dedicated to the rear window 22, thereby reducing the cost of the parts. The configuration of 30 can be simplified.

  The present invention is configured as described above, and its operation will be described next. When a seated person (not shown) seated on a seat (not shown) operates an operation switch (not shown), the motor M rotates, the groove C of the wire W meshes with the gear, and the wire W becomes a guide groove. It is pushed into 12A and 13A. Then, the slider portion S fixed to the tip end portion of the wire W is guided upward in the guide grooves 12A and 13A, and the frame 32 moves from the open position P3 to the shielding position P1 through the intermediate position P2. When the frame 32 moves upward, the shade 31 is drawn upward from the inside of the case 33 to cover the entire side window 20 at the same time, and the support pins 34 move inside the elongated holes H1, whereby the frame 32 is moved. It moves in the front-rear direction relative to both support portions H. When the frame 32 reaches the shielding position P1, the rotation of the motor M is stopped.

  As described above, in the present embodiment, the support portion H is disposed outside the guide groove 12A to reduce the size of the division bar 12, and the frame 32 is disposed offset from the slider portion S toward the vehicle interior side. The shade 31 can be disposed on the interior side of the division bar 12. Accordingly, the entire side window 20 can be covered by the single shade 31 and parts such as a shade, a winding device, and a wire that cover the rear window 22 are not required, and the number of parts is reduced. A simple structure can be obtained.

  Further, since the frame 32 is guided in the vertical direction by the guide groove 13A of the front frame portion 13 and the guide groove 12A of the division bar 12, the frame 32 can be supported in a stable posture. In addition, since the frame 32 can be moved in the front-rear direction by the long hole H1 and the support pin 34, a simple configuration can be achieved.
