Description

Technical Field

[0001] The present invention relates to a vehicle sunshade used for shading a windshield or the like for the purpose of blocking direct sunlight and suppressing an increase in the vehicle interior temperature.

Background Art

[0002] Since the front windshield of a vehicle or the like is usually transparent or translucent, if no sunshade measures are taken, the vehicle interior temperature rises due to the intrusion of direct sunlight, and it becomes particularly hot in summer. Various vehicle sunshades have been proposed as temperature countermeasures.

[0003] Patent Document 1 discloses a vehicle sunshade including a sunshade base fabric having an area equivalent to the area of the front windshield and an annular spring material enclosed in the left and right regions excluding the center of the sunshade base fabric. Due to the presence of the annular spring material, it has overall shape retention. When mounting, it is leaned against to cover the front windshield, and for example, the upper side portion is clamped by a sun visor. Patent Document 1 also discloses a vehicle sunshade corresponding to the left and right side windows (front door windows). This includes a sunshade base fabric having an area equivalent to the area of the side window and an annular spring material enclosed along the periphery of the sunshade base fabric, and when mounting, it is attached, for example, with a suction cup attached to the front surface side of the sunshade base fabric. When storing, in any type, the annular spring material can be twisted into an 8 shape to be compactly folded into a circular shape.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Since the area of the windshield varies depending on the vehicle type, the vehicle sunshade described in Patent Document 1 cannot completely block direct sunlight when a gap occurs.

[0006] Also, depending on the vehicle type, in order to widen the driver's field of view, there is a small window glass, which may also be called a delta window depending on its shape, between the windshield and the front door glass. When trying to block direct sunlight from this small window glass, since there is no stopper like a sun visor on the small window glass, simply extending the conformability structure for the windshield by the area corresponding to the small window glass cannot solve the problem. As described in Patent Document 1, if a configuration corresponding to the windshield and the small window glass individually is adopted, the installation work becomes complicated, and storage and storage also become troublesome. In addition, the manufacturing process also becomes complicated, and an increase in manufacturing cost is inevitable.

[0007] The present invention was devised in view of the above points, and its object is to provide a vehicle sunshade that can be easily dealt with in a single configuration even if the size of the glass surface varies depending on the vehicle type or there is a small window glass.

Means for Solving the Problems

[0008] In order to achieve the above object, the vehicle sunshades (2A, 2B, 2C) of the present invention are vehicle sunshades installed so as to cover the glass surface from the inside of the vehicle, and include a shade main body portion (4) having an area covering at least a part of the glass surface (22), an extension portion (6A, 6B) connected to the shade main body portion (4) by a flexible sheet material and having an area covering the remaining portion of the glass surface (22) or another glass surface (30A, 30B) located in the vicinity of the glass surface (22), and an adsorption sheet (8A, 8B) fixed to the side of the extension portion (6A, 6B) facing the glass surface (30A, 30B) and fixing the extension portion (6A, 6B) to the glass surface (30A, 30B). Further, this adsorption sheet (8A, 8B) may be a sheet material made of PVC and fixed to the glass surface (30A, 30B) by electrostatic adsorption.

[0009] According to the vehicle sunshade of the present invention, since the flexible extension part is fixed to the glass surface with an adsorption sheet, it can be fixed by a simple operation of simply pressing the adsorption sheet against the glass surface, and can be repeatedly used without accidentally coming off. As a result, the small window glass provided between the windshield and the front door glass can also be easily shaded. Further, if a part of the windshield is covered with the shade main body part and the remaining part is covered with the extension part, it is possible to arbitrarily cope with changes in the size of the windshield due to differences in vehicle models.

[0010] Also, in the above vehicle sunshades (2A, 2B, 2C), the shade main body part (4) may be formed in series with the same sheet material as the extension parts (6A, 6B). According to this, the manufacturing process of the shade main body part and the extension part is less, and the manufacture of the vehicle sunshade becomes easy.

[0011] Also, in the above vehicle sunshades (2A, 2B, 2C), the shade main body part (4) has an area covering the windshield (22), and the extension parts (6A, 6B) have an area covering the small window glass (30A, 30B) located between the windshield (22) and the front door glass (26A, 26B). According to this, the small window glass for expanding the driver's field of view can also be easily shaded.

[0012] Also, in the above vehicle sunshades (2A, 2B, 2C), the shade main body part (4) may have a shape-retaining property and be configured to be able to maintain a certain installation posture via the fixing members (24A, 24B) provided on the vehicle side with respect to the windshield (22). According to this, after positioning the shade main body part, the extension part can be fixed to the small window glass without worrying about the shade main body part.

[0013] Further, in the above vehicle sunshades (2A, 2B, 2C), the shade main body (4) may be configured to enclose ring-shaped shape-retaining members (12A, 12B) made of elastic linear bodies on the left and right and be foldable at the central part. According to this, shape retention can be imparted to the flexible shade main body, and folding becomes easy.

[0014] Further, in the above vehicle sunshade (2A), the adsorption sheets (8A, 8B) may be formed in a strip shape with a certain width and arranged at the ends of the extension parts (6A, 6B) so as to extend in the vertical direction. According to this, the extension parts can be detachably fixed to the glass surface with a small adsorption area.

[0015] Further, in the above vehicle sunshade (2B), the adsorption sheets (8A, 8B) may be formed in a strip shape whose width narrows downward and arranged at the ends of the extension parts (6A, 6B) so as to extend in the vertical direction. According to this, the extension parts can be detachably fixed to the glass surface with a small adsorption area.

[0016] Further, in the above vehicle sunshade (2C), the adsorption sheets (8A, 8B) may be formed in a triangular shape whose width narrows downward and arranged above the ends of the extension parts (6A, 6B). According to this, the extension parts can be detachably fixed to the glass surface with an even smaller adsorption area. Since the adsorption area is small, the fixing operation becomes easy.

Advantages of the Invention

[0017] According to the present invention, even if the size of the glass surface varies depending on the vehicle type or there is a small window glass, it can be easily dealt with in a single configuration.

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] [First Embodiment] The first embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 is a front view showing the vehicle sunshade 2A according to the present embodiment (a view seen from the front of the vehicle when in use). The vehicle sunshade 2A is installed so as to cover the glass surface from the inside of the vehicle. The direction of arrow X is the width direction (left-right direction) of the vehicle, the direction of arrow Y is the front-rear direction of the vehicle (the thickness direction of the windshield), and the direction of arrow Z is the height direction (up-down direction) of the vehicle, respectively. The front side in the direction of arrow Y indicates the windshield 22 side, and the back side indicates the inside of the vehicle. Therefore, the back surface of the vehicle sunshade 2A in FIG. 1 is the surface visible from inside the vehicle. Hereinafter, the vehicle sunshade 2A will be simply abbreviated as the sunshade 2A.

[0021] The sunshade 2A includes a shade main body 4 having an area that covers at least a part (here, the entire surface) of the windshield 22 (see FIG. 4), and is continuously provided on the shade main body 4 with a flexible sheet material so as to extend outward in the left - right direction. It has extension parts 6A, 6B having an area that covers another glass surface located in the vicinity of the windshield 22, here, the small window glasses 30A, 30B (see FIG. 4) located between the windshield 22 and the front door glasses 26A, 26B. Adsorption sheets 8A, 8B are fixed to the side of the extension parts 6A, 6B facing the windshield 22 for detachably adsorbing and fixing (adhering and fixing) the extension parts 6A, 6B to the small window glasses 30A, 30B. Reference numeral 10 indicates a rubber string for tying the sunshade 2A in a rolled - up state when it is stored.

[0022] The shade main body 4 and the extension parts 6A, 6B are integrally formed of the same flexible sheet material. Specifically, it is formed of a single piece of fabric made of a thin polyester - based resin on the micron order, and aluminum that reflects light is vapor - deposited on the surface (front). The back surface of the fabric (the surface visible from inside the vehicle) is black. The shade main body 4 has shape - retaining properties and can maintain a certain installation posture with respect to the windshield 22 via a fixing member. That is, in a state where the lower end is placed on the dashboard 36 (see FIG. 4), for example, the upper end part can be fixed by the sun visors 24A, 24B (see FIG. 4) as fixing members, so that the windshield 22 can be covered in a propped - up state.

[0023] A narrow - band fabric 18 is sewn around the entire outer edge of the sunshade 2A. As shown in FIG. 3(a), the narrow - band fabric 18 covers the outer edge of the sunshade 2A (the outer edge of the sheet material) straddling the front side and the back side, and is sewn in a state where its cross - section is curved in a substantially U - shaped state. Reference numeral 9 in FIG. 3 etc. indicates the stitch line for sewing the narrow - band fabric 18 to the outer edge of the sunshade 2A. As shown in FIG. 3(b), the outer edges of the left - right ends of the extension parts 6A, 6B in the sunshade 2A are sewn with the narrow - band fabric 18 from above in a state where the fabric (sheet material) of the extension part 6B and the adsorption sheet 8B are overlapped front - to - back.

[0024] The shade main body 4 encloses ring-shaped shape-retaining members 12A and 12B made of elastic linear bodies in the left and right regions excluding the central part, and can be bent (folded) at the central part. The shape-retaining members 12A and 12B are formed in a substantially rectangular ring shape from spring steel wire rods and are arranged symmetrically with respect to the left and right lines. As shown in FIG. 2, the shape-retaining member 12B having a rectangular cross section is arranged on the back (rear) side of the shade main body 4, and is covered entirely around by a narrow fabric 14 (omitted in FIG. 1) sewn to the shade main body 4 and made of the same fabric as the sunshade 2A so as not to move. In FIG. 2, reference numeral 16 indicates the left and right stitch lines of the narrow fabric 14. The color of the outer surface of the narrow fabric 14 is the same black as the back of the sunshade 2A so as not to cause a sense of incongruity when viewed from inside the vehicle. The same applies to the shape-retaining member 12A.

[0025] As shown in FIG. 1, the adsorption sheets 8A and 8B in the present embodiment are formed in a strip shape with a certain width and are arranged so as to extend in the vertical direction at the left and right ends of the extension parts 6A and 6B. As shown in FIG. 3(b), the adsorption sheet 8B covers the outer edges of the extension parts 6A and 6B in a state where each side of the outer edge except the inner vertical sides 8A-1 and 8B-1 (see FIG. 1) coincides with the outer edges (the outer edges of the sheet material), and is sewn and fixed with a narrow fabric 18 at the stitch line 9. The same applies to the adsorption sheet 8A. The adsorption sheets 8A and 8B are thin sheets (single-layer films) made of PVC (polyvinyl chloride), and are sheet materials having self-adhesive properties that can be adsorbed (attached) to a smooth surface such as a glass surface. When the adsorption sheets 8A and 8B are pressed against a glass surface having a smooth surface such as the windshield 22, they are adsorbed (electrostatically adsorbed) to the glass surface due to the self-adhesive properties. Since it is adsorption (attachment) by static electricity without using an adhesive, removal (peeling) and adsorption fixation can be repeated. Further, since it is adsorption by self-adhesive properties, there is no risk of glue residue or dirt on the glass surface after peeling.

[0026] Since the shade main body 4 has the shape retention property by the shape retention members 12A and 12B as described above, the gravity of the shade main body 4 does not reach the extension parts 6A and 6B when the lower end is placed on the dashboard 36. Therefore, it is sufficient for the suction sheets 8A and 8B to support the weight corresponding to the area of the sheet material constituting the extension parts 6A and 6B. From this perspective, the areas of the suction sheets 8A and 8B are set.

[0027] Referring to FIGS. 4 to 6, the usage method of the sunshade 2A will be described. FIG. 4 shows the front part inside the vehicle 20 in a state where the sunshade 2A is not used. Sun visors 24A and 24B are provided at the upper part of the windshield 22, and small window glasses 30A and 30B for widening the driver's field of view are provided between the windshield 22 and the front door glasses 26A and 26B with the pillar 28 interposed therebetween. Reference numeral 32 denotes a rearview mirror (room mirror), and 34A and 34B denote side mirrors (door mirrors).

[0028] FIG. 5 shows a state in which the windshield 22 and the small window glasses 30A and 30B are covered and shaded using the sunshade 2A. The windshield 22 is covered with the shade main body 4. The lower end of the shade main body 4 is placed on the dashboard 36, and the upper end part is received by the sun visors 24A and 24B so as not to fall. After installing the shade main body 4 so as not to fall, the flexible extension parts 6A and 6B are appropriately extended to cover the small window glasses 30A and 30B one by one, and the suction sheets 8A and 8B are pressed against the glass surfaces of the small window glasses 30A and 30B and suction-fixed. In this way, the windshield 22 and the small window glasses 30A and 30B can be shaded with a simple operation. Since the base side (the connection side to the shade main body 4) of the extension parts 6A and 6B is supported by the shade main body 4 so as not to hang down, it is only necessary to hold and press the suction sheet 8A and 8B side by hand. Since the extension parts 6A and 6B have flexibility, they can easily follow the uneven changes due to the presence of the pillar 28 or the like and the frame covering the periphery of the small window glasses 30A and 30B and can cover well.

[0029] FIG. 6 schematically shows the installation state of the sunshade 2A shown in FIG. 5 in an easy-to-understand manner. Note that in FIG. 6, the thicknesses of the respective members are omitted. As described above, after installing the shade main body 4, the suction sheets 8A and 8B of the left and right extension parts 6A and 6B are respectively suction-fixed inside the small window glasses 30A and 30B (inside the vehicle) and closer to the rear of the vehicle.

[0030] When fixing the extension parts 6A and 6B to the small window glasses 30A and 30B, a method of inserting the thin sheet-like claws provided at the edges of the extension parts 6A and 6B into the gaps between the pillars and window frames covering the peripheries of the small window glasses 30A and 30B can be assumed. However, in this method, the gaps may widen and the claws may come off during repeated use, and there may be no insertion gap depending on the vehicle type. On the other hand, since the suction sheets 8A and 8B according to the present embodiment are fixed by suction to the glass surface itself to be covered, the above problems do not occur. Further, since the suction fixing is maintained until the suction sheets 8A and 8B are peeled off, the light-shielding state is not unexpectedly released.

[0031] When the sunshade 2A is not in use, the shade main body 4 has shape-retaining properties as it is, so it is bulky. Since the shape-retaining members 12A and 12B have reversible elastic deformability, as shown in FIG. 7(a), the shape-retaining member 12A on the left side of the shade main body 4 is deformed into a figure-eight shape, and then, as shown in FIG. 7(b), it can be made compact like a double ring by folding it around the intersection. Although the fabric of the sunshade 2A is omitted, it has flexibility, so it easily deforms following the folding operation of the above-described shape-retaining member 12A. When the shape-retaining member 12B on the right side of the shade main body 4 is folded in the same manner and overlapped with the shape-retaining member 12A, the whole can be made compact, and it can be fastened so as not to expand by tying it with the rubber string 10. By folding it in this way, it does not become bulky, so it can be easily stored in a door pocket or the like. When in use, when the tying with the rubber string 10 is removed, it automatically expands (pops up) due to the elasticity of the shape-retaining members 12A and 12B and can immediately be put into a use state.

[0032] [Second Embodiment] The second embodiment will be described with reference to FIG. 8. The same parts as or parts that can be regarded as the same as those in the first embodiment are denoted by the same reference numerals, and the descriptions of the configurations and functions already made will be omitted as appropriate unless particularly necessary (the same applies to the following other embodiments).

[0033] In the sunshade 2B according to the present embodiment, the adsorption sheets 38A and 38B are formed in a strip shape whose width gradually narrows downward, and are arranged at the left and right ends of the extension portions 6A and 6B so as to extend in the vertical direction. As described above, the gravity acting on the extension portions 6A and 6B is small, being the weight of the fabric with the area of only the extension portions 6A and 6B, and in order to prevent slipping or slackening, it is only necessary to firmly fix the upper side, so the shape is such that the width narrows downward.

[0034] [Third Embodiment] The third embodiment will be described with reference to FIG. 9. In the sunshade 2C according to the present embodiment, the adsorption sheets 40A and 40B are formed in a triangular shape whose width gradually narrows downward, and are arranged above the left and right ends of the extension portions 6A and 6B. Although the adsorption area is smaller than that in the first and second embodiments, since the upper part can be firmly fixed, the extension portions 6A and 6B will not slip or slacken. Since the adsorption area is small, the cost of the adsorption sheets 40A and 40B can be reduced, and the adsorption fixing operation can be easily performed with one touch.

[0035] The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea described in the utility model registration claims, the specification, and the drawings. For example, in each of the above embodiments, the inner sides of the adsorption sheets 8A, 8B, 38A, 38B, 40A, and 40B are not fixed (sewn) to the extension parts 6A and 6B, but they may be fixed. Also, although sewing is exemplified as the method of fixing to the extension parts 6A and 6B, fixing by adhesion or fixing with double-sided tape may also be used. Further, the shapes and numbers of the adsorption sheets 8A, 8B, 38A, 38B, 40A, and 40B are not limited to those shown in the above embodiments, and can be appropriately set within the range that can maintain the state of covering the small window glasses 30A and 30B with the extension parts 6A and 6B. Also, the material of the adsorption sheets 8A, 8B, 38A, 38B, 40A, and 40B is not limited to the above, and any material that can be repeatedly peeled off and adsorbed and fixed is acceptable.

[0036] In each of the above embodiments, the shade main body 4 is sized to cover the entire front glass 22. However, in order to accommodate changes in the size of the front glass 22 due to different vehicle models, a configuration may be adopted in which the shade main body 4 covers a part of the front glass 22, and the remaining part of the front glass 22 is covered by the extension parts 6A and 6B.

[0037] In each of the above embodiments, the shade main body 4 and the extension parts 6A and 6B are integrally formed with a single flexible sheet. However, a configuration may be adopted in which the extension parts 6A and 6B are formed individually and attached to the shade main body 4 by means such as sewing. Also, although the cross-sections of the shape-retaining members 12A and 12B are rectangular, they may be other shapes such as circular or elliptical. Also, the ring-like shape of the shape-retaining members 12A and 12B is not limited to the above, and can be appropriately determined within the range that enables the shade main body 4 to be leaned against. Furthermore, the material of the shape-retaining members 12A and 12B can be appropriately selected within the range that enables compact storage and automatic deployment as shown in FIG. 7.

[0038] In each of the above embodiments, the shape-retaining members 12A and 12B are incorporated in the shade main body 4 to impart shape-retaining properties. However, the shade main body 4 may be formed in a foldable bellows shape or the like using a member whose material itself has shape-retaining properties, and flexible extension parts 6A and 6B may be added thereto. Further, although the shade main body 4, the extension parts 6A and 6B are formed by vapor-depositing aluminum on the surface of a single-layer fabric, a multi-layer structure may also be used, and vapor-depositing aluminum is not an essential requirement as long as light-shielding properties can be obtained. Furthermore, the colors of the front and back of the sunshades 2A, 2B, and 2C are not limited to those described above. Also, although the shape-retaining members 12A and 12B are arranged on the back surface side of the shade main body 4, they may be arranged on the front surface side.

[0039] In each of the above embodiments, the upper end of the shade main body 4 is fixed by the visors 24A and 24B which are members on the vehicle side. However, it may be configured to be fixed to the front glass 22 using a member such as a suction cup attached to the shade main body 4.
