Description

  The present invention relates to a sunshade structure.

2. Description of the Related Art Conventionally, there is a sunshade structure provided with a sheet-shaped shade provided on a vehicle room side of a door window frame for a rear seat of a vehicle to block sunlight from the door window (Patent Document 1).
The conventional shade is configured to be deployed in an inclined state along a door window whose upper part is inclined toward the passenger compartment. In addition, the main body case that houses the winding shaft that winds the shade in the conventional sunshade structure has a slit through which the shade is inserted. The slit is opened right above the winding shaft in consideration of the appearance from the passenger compartment side.
Then, the user pulls out the shade wound on the winding shaft, and locks the end of the shade on a locking portion provided on the upper portion of the door window frame, whereby the shade is developed along the door window. When the lock is released, the shade is wound up by the winding shaft.
Here, in the conventional sunshade structure, when the shade is pulled out from the slit and wound up, the main body case has an end portion between the shade and the door trim so that the shade does not directly contact the door trim and is not damaged. A vertically extending portion is required so as to intervene.
For this reason, when the main body case is manufactured by extrusion molding, the upper end of the main body case becomes linear, and in order to adjust the appearance, the upper end of the door trim must be linear, and the degree of freedom in design has not been high. . In addition, since the main body case requires a portion extending in the vertical direction, there is room for improvement in manufacturing cost.

(Embodiment)
Hereinafter, embodiments for implementing the present invention (hereinafter, embodiments) will be described in detail with reference to the drawings. Unless otherwise specified, the outside of the vehicle, the side of the cabin, the front, the rear, the left, the right, the upper and the lower indicate the directions around the vehicle.
In the following embodiments, the sunshade structure 100 used for the door window W on the rear seat side of the vehicle will be described as an example. However, the present invention is not limited to the door window W on the rear seat side of the vehicle. The present invention can also be applied to other windows such as a window on the rear seat side of a vehicle that is not installed and a rear window.

FIG. 1A is a front view of a door (vehicle body) 10 in a state where the screen 3 is wound and housed, and FIG. 1B is a front view of the door (vehicle body) in a state where the screen 3 is wound and housed. FIG. 1C is a perspective view of the door (vehicle body) 10 in a state in which the screen 3 is wound up and stored, as viewed from the rear compartment side. is there.
FIG. 2 is a sectional view taken along the arrow A in FIG. 1A in a state where the screen 3 is pulled out and expanded.
FIG. 3 is a sectional view taken along the arrow A in FIG. 1A in a state where the screen 3 is wound up and stored.

As shown in FIGS. 1 to 3, the sunshade structure 100 is applied to a door window W.
The sunshade structure 100 is provided inside a door (vehicle body) 10 below the door window W, and is provided with a take-up cylinder 2 housed in a case 1, a screen 3 that can be taken up by the take-up cylinder 2, and a screen 3. A locking portion 20 which is capable of engaging and disengaging the end 3e with a locking position P above the door window W. Note that the locking portion 20 may be provided on a window frame of the door 10, or may be provided, for example, near a door window W on a ceiling which is a part of the vehicle body.

  The door 10 has a vehicle body slit 10 s through which the screen 3 is inserted between an end 11 e of the door trim 11 on the vehicle exterior side and an end 12 e of the door panel 12 on the vehicle interior side.

  The take-up cylinder 2 is rotatably supported with respect to the case 1 and fixes one end of a sheet-like screen 3. The take-up cylinder 2 is urged by a torsion spring (not shown) or the like in a direction in which the screen 3 is taken up. Therefore, when the take-up cylinder 2 is rotated in the take-up direction (clockwise) from the state shown in FIG. 2, the screen 3 is taken up by the take-up cylinder 2. Conversely, when the take-up cylinder 2 is rotated in the pulling-out direction (counterclockwise) from the state shown in FIG. 3, the screen 3 is pulled out from the take-up cylinder 2.

The screen 3 blocks light that enters from the outside of the vehicle toward the cabin, and has a predetermined light blocking property.
One end of the screen 3 is fixed to the take-up cylinder 2, and an end 3 e, which is the other end, is removably locked to a locking portion 20 above the door window W.
Since the screen 3 is repeatedly wound up and pulled out by the winding cylinder 2, it has predetermined flexibility and durability.
Then, the screen 3 is deployed so as to cover the door window W as shown in FIG.

The case 1 is made of aluminum manufactured in a uniform cross section by extrusion molding, has a substantially cylindrical shape as a whole, and is provided inside the door 10 in a posture in which the longitudinal direction of the vehicle is the longitudinal direction.
The case 1 has a case slit 1 s at an upper portion, which extends in the vehicle front-rear direction and allows the screen 3 to enter and exit.

Then, as shown in FIG. 2, the case 1 connects the contact position C of the screen 3 with respect to the winding cylinder 2 and the locking position P with the end 3 e of the screen 3 locked by the locking portion 20. A sliding contact portion 1f that deflects the screen 3 is provided outside the vehicle with respect to the virtual line L. Thus, even if the user pulls out the end 3e of the screen 3 toward the locking portion 20, the screen 3 does not come into contact with the end 11e of the door trim 11, which is the cabin side of the vehicle body slit 10s, and smoothly. It can enter and exit in the vehicle body slit 10s.
Therefore, in order to protect the end 11e of the door trim 11 as in the related art, it is not necessary to extend a part of the case 1 to the vehicle body slit 10s, and the end 11e of the door trim 11 is straightened according to the shape of the case 1. Since there is no design restriction such as the shape, the degree of freedom of design can be increased and the manufacturing cost of the case 1 can be reduced. Further, since the width of the vehicle body slit 10s can be set to a size having a margin with respect to the thickness of the screen 3, the overall size of the door 10 can be made compact and the appearance is good.

  The imaginary line L intersects with the door trim 11 at the vehicle compartment side edge of the vehicle body slit 10s. That is, as shown in FIG. 2, the end 11e of the door trim 11 exists outside the vehicle with respect to the imaginary line L. By setting the position of the end 11e of the door trim 11 in this way, even if the occupant looks near the vehicle body slit 10s, the inside is not conspicuous through the vehicle body slit 10s, so that the appearance is good.

The screen 3 is inclined along the inclination of the door window W in the unfolded state, and the vehicle body slit 10 s is located directly above the winding cylinder 2. That is, the vehicle body slit 10 s is open toward the upper side without facing the direction of the locking portion 20 with respect to the winding cylinder 2.
As described above, even when the screen 3 is inclined toward the passenger compartment along the inclination of the door window W, since the vehicle body slit 10s is located immediately above the winding cylinder 2, the vehicle body slit 10s faces the passenger compartment. Even if the occupant looks in the vicinity of the vehicle body slit 10s, the inside is not conspicuous through the vehicle body slit 10s, so that the appearance is good.

  The case 1 has a cylindrical portion provided with a case slit 1s through which the screen 3 is inserted. The sliding contact portion 1f is provided at an edge of the case slit 1s on the vehicle compartment side. Accordingly, since the sliding contact portion 1f can be formed by using a part of the case 1, it is easy to extrude and the manufacturing cost of the case 1 can be reduced. The surface of the sliding contact portion 1f may be curved or polished to reduce frictional resistance with the screen 3.

The case slit 1s is provided below the vehicle body slit 10s.
As a result, the case 1 including the case slit 1s is disposed below the vehicle body slit 10s, and therefore is not seen from the occupant through the vehicle body slit 10s. Therefore, since the case 1 is not exposed to the passenger compartment, surface painting for improving the appearance can be omitted, and the manufacturing cost can be reduced.

The door (vehicle body) 10 has a door trim 11 having a laminated structure including a base material 13 and a skin 14 covering the base material 13 on the passenger compartment side.
The upper end 11e of the door trim 11 forms a part of the vehicle body slit 10s, and the skin 14 is bent back so as to cover the end of the base material 13. Thereby, since the skin 14 is exposed at the end portion 11e that constitutes a part of the vehicle body slit 10s, the vehicle body slit 10s is not conspicuous, and the appearance near the vehicle body slit 10s is further improved.

  The upper end 11e of the door trim 11 is formed in a non-linear shape. Thereby, in order to obtain the effect of reducing the manufacturing cost, even if the case slit 1s is made straight, it is not necessary to make the end 11e straight so that the degree of freedom in design can be increased.

  As described above, the preferred embodiment of the present invention has been described in detail. However, the sunshade structure 100 according to the present invention is not limited to the above-described embodiment, but may fall within the scope of the present invention described in the appended claims. Various modifications and changes are possible.

  According to the present invention, the sunshade structure 100 is provided inside the door (vehicle body) 10 below the door window W, and the take-up cylinder 2 housed in the case 1 and the screen that can be taken up by the take-up cylinder 2 3 and an engaging portion 20 which is capable of engaging and disengaging an end 3e of the screen 3 with an engaging position P above the door window W. The door (vehicle) 10 has a vehicle body slit 10s through which the screen 3 is inserted. The case 1 has a position higher than the virtual line L connecting the contact position C and the locking position P of the screen 3 with respect to the winding cylinder 2 in a state where the end 3 e of the screen 3 is locked by the locking portion 20. Since the sliding portion 1f deflects the screen 3 on the outside, the screen 3 slides on the door trim 11 while moving the vehicle body slit 10s as far as possible out of the line of sight of the occupant. Not be so, can unobtrusively in the vicinity of the vehicle body slit 10s. Therefore, the degree of freedom in designing the waistline portion of the door 10 can be increased, and the manufacturing cost of the case 1 can be reduced.
