The plates 61, 62, and 63 constituting the plate-shaped member 6 are arranged with their ends overlapping in the longitudinal direction, and have a configuration in which the plate-shaped members 84 and 89 are connected to each other. The plate-shaped members 2 to 6 are each foldable (see FIG. 4), but are configured to be one plate-shaped member by supporting one or two points from one surface side. (See FIG. 5). When a connecting portion such as a hinge that stops when it spreads flat at 180 degrees is used, the plates constituting each plate-shaped member can be arranged so as not to overlap. In FIG. 2A, in order to facilitate understanding of the superposed state, the sheet-shaped members 80 to 89 are shown by an outer frame and shown in a transparent state. The sheet-shaped members 80 to 89 are formed by an adhesive or a heat welding method at the portions 80a, 81a, 82a, 83a, 84a, 85a, 86a, 87a, 88a, 89a shaded in FIG. 2A. It is joined.

By adopting the above configuration, as shown in FIG. 4, the plate-shaped members 2, 3, 4, 5, and 6 can be folded in three. 5A and 5B are views for explaining the case where the sunshade 1 is attached to the windshield 150 of the car, and show the vicinity of the windshield 150 of the car. As shown in FIGS. 5A and 5B, the plate-shaped members 2, 3, 4, 5, and 6 use suction cups 101, 102, and 103 as shown, and one point or two from one surface side. By supporting the points, it becomes one plate-shaped member. When viewed as a whole, the sunshade 1 may be provided with a sufficient number of suction cups so that the sunshade can be fixed to an object such as a windshield 150. For example, the upper and lower plates 21, 23, 61 of the plate-shaped members 2, 6 A configuration may be adopted in which suction cups are provided in each of 63 (state of FIG. 5A) and suction cups are provided in the central plate 42 of the plate-shaped member 4 (state of FIG. 5B). It should be noted that the configuration is not limited to the case of folding in three, and the plate-shaped members 2, 3, 4, 5, 6 and each of the four and five plates may be configured. In this case, for example, the plates are added around the plate 22 of the plate-shaped member 2 in the same stacking method as the plates 21 and 23. Even in this case, as shown in FIGS. 5A and 5B, one plate-shaped member can be formed by supporting one or two points from one surface side.

6 (a), (b), (c), and (d) show the end of one (one) plate-shaped member extending in the longitudinal direction among the plate-shaped members 2, 3, 4, 5, and 6. The thickness a, the intervals s1 and s2, the length b from the end of the side extending in the longitudinal direction of the adjacent (other) plate-shaped member facing each other to the line-shaped portion, and the side extending in the longitudinal direction of one plate-shaped member. It is a figure for demonstrating the relationship with the length c from the end portion of 1 to the line-shaped portion of the other plate-like member. FIG. 6A is a view corresponding to, for example, a plan view of FIG. 1B, in which three plate-shaped members 110, 111, and 112 similar to those of the plate-shaped members 2 to 6 having a thickness a are arranged in a sheet shape. A state in which the sheet-like members 113 and 114 similar to the members 80 to 89 are connected to each other is shown. FIG. 6B shows the positional relationship that occurs when one plate-shaped member is superposed on the other plate-shaped member under the situation shown in FIG. 6A.

Between the plate-shaped members 110 and 111 of FIG. 6 (b), as shown in FIG. 6 (c), a ² + b ² ≤ c ^{2, that} is, the square of the length a is added to the square of the length b. The relationship that the value is less than the square of the length c is established, and since the sheet-shaped members have a sufficient length, they can be overlapped without hitting the corners of the plate-shaped members. Between the plate-shaped members 111 and 112 of FIG. 6B, a ² + b ² > c ^{2, that} is, the value obtained by adding the square of the length a to the square of the length b is the value of the square of the length c. Since the sheet-shaped members are longer than each other, the length of the sheet-shaped members is insufficient, and the corners of the plate-shaped members hit each other. However, as shown in FIG. 6D, when the relationship of a <c is established, they can be overlapped. That is, it can be seen that the relationship of a <c is an essential requirement, and further, it is preferable to satisfy the relationship of a ² + b ² ≤ c ² . The plate-shaped members 2 to 6 of the sunshade 1 shown in FIGS. 1 and 2 satisfy the above-mentioned relationship (a <c relationship is an essential requirement, and further, a ² + b ² ≤ c ² relationship is satisfied. Is preferable), and they are connected by sheet-shaped members 70 to 73.

For example, between the plate-shaped member 2 and the plate-shaped member 3, between the plate-shaped member 3 and the plate-shaped member 4, between the plate-shaped member 4 and the plate-shaped member 5, and between the plate-shaped member 5 and the plate-shaped member 6. The space is set to the relationship between the plate-shaped member 110 and the plate-shaped member 111 shown in FIG. 6A, or the relationship between the plate-shaped member 111 and the plate-shaped member 112 shown in FIG. 6A.

FIG. 7 is a diagram for explaining the value of the interval s required when the plate-shaped members 2 to 6 are folded in three in the longitudinal direction as shown in FIG. 4 and folded in ninety-nine turns. , A figure corresponding to the cross-sectional view taken along the line AA'in FIG. 4 is shown. As shown in the figure, if there is an interval s of the size (4 × a) corresponding to the thickness of four plate-shaped members, the plate-shaped members 2 to 6 can be folded in a zigzag manner. For example, when a plastic corrugated cardboard having a thickness of 2 mm is used as the material of the plate-shaped member, the required interval s is 8 mm. Actually, it is set to 9 to 10 mm by adding about 1 mm in consideration of manufacturing error and the like. This value is several tens of mm between the connecting portions derived from the conventional sunshade diagram shown in FIG. 8 when the windshield size of the truck (loading weight 2t to 10t) generally recognized at the time of filing the application of the present application is taken into consideration. The shading rate is improved at intervals of a fraction of the size of the above. Furthermore, if the length b from the end of the side extending in the longitudinal direction of the other plate-shaped member adjacent to one plate-shaped member to the line-shaped portion is, for example, 40 mm, the movable width is substantially 50 mm. Will have.

For example, the size of a truck windshield is in the range of 1600 mm to 2300 mm. In the case of the conventional sunshade 200 for trucks, the distance between the first and second front-side connecting portions 205 and 207 is 48 mm to 69 mm. On the other hand, in the case of the sunshade of the present invention, if the distance between the plate-shaped members 2 to 6 is set to 10 mm, the length (width) of the plate-shaped members 2 to 6 in the lateral direction can be obtained by the conventional connection method. ) Is 312 mm to 452 mm. In the sunshade 1 of the present invention, the length b from the end of the side extending in the longitudinal direction of the adjacent (other) plate-shaped members of the sheet-shaped members 70 to 73 facing each other to the line-shaped portion (shown in FIG. 6B). The length of b) is set to 35 mm. By adopting this configuration, even if the length (width) of the plate-shaped members 2 to 6 in the lateral direction is set to 452 mm, the total width of the sunshade 1 can be adjusted in the range of 452 mm to 312 mm. .. Further, as shown in FIG. 3, it can be deformed into a fan shape according to the shape of the front window. As described above, the sunshade 1 of the present invention has an advantage that it can be mounted on a front window having a wide width and shape with one product. Further, the interval is only 10 mm, and heat propagation from the connecting portion by the sheet-shaped member to the inside of the vehicle can be efficiently suppressed as compared with the case where the interval is 48 mm to 69 mm as in the case of the conventional sunshade 200 for trucks. Moreover, when not in use, it can be folded compactly and has the advantage that it can be stored in a side pocket provided on a car door or a glove box.

The present invention is not limited to the configurations of the various embodiments described above, and various modifications can be made without changing the gist of the invention. For example, the spacing required to fold a plate-shaped member in a zigzag is for a soft material that collapses thinly when the edge of the plate-shaped member is pulled, or when the sheet-shaped member has elasticity. , Can be made even narrower. Further, the number of plate-shaped members to be used and the number of rectangular plates constituting the plate-shaped members can be increased or decreased within a range in which the effects of the invention can be exhibited.

The plate-shaped member of the present invention can be used not only for the windshield of a car, but also for the side glass and the rear glass of a car, and if the size is increased, it can be used as a shade or a blindfold for a window facing a garden or a balcony. , Can be used.
