Description

[Technical Field]

[0001] The present invention relates to a sunshade for a vehicle. [Background technology]

[0002] Conventional vehicle sunshades are placed on the inside of the front windshield of a vehicle such as an automobile when the vehicle is parked outdoors, and can block or insulate the sun's radiation that enters the vehicle through the windshield, thereby preventing the temperature inside the vehicle from rising.

[0003] Furthermore, among such sunshades, for example, there are known ones that have a plate-like shape with an external shape that matches the windshield, and are supported by the top surface of the dashboard inside the vehicle and the sun visor or rearview mirror, thereby blocking or insulating the sunlight that enters the vehicle interior through the windshield, and have patterns or text information printed on the front side that can be displayed to the outside through the windshield (see, for example, Patent Documents 1-3).

[0004] The automobile sunshade described in Patent Document 1 is made of rectangular, light-blocking cardboard, has multiple folds parallel to the width, and is configured to be foldable like an accordion.The front surface is equipped with an anti-theft display made of a phosphorescent material that glows in the dark, indicating that an anti-theft alarm is installed.

[0005] The automobile sunscreen described in Patent Document 2 consists of a large plate-like body that is approximately the same size as the windshield of an automobile, a plurality of folding lines formed vertically at predetermined intervals across the width of the plate, and a desired declarative advertising display attached to the front surface of the plate.

[0006] In addition, the sunshade described in Patent Document 3 has a flexible decorative layer adhered to the windshield side of the parasol when it is extended toward the windshield, and the decorative layer is removable and replaceable using hook / loop fastenings or metal snaps, etc., allowing the user to create identifiers, advertisements, or messages as needed. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Utility Model Registration No. 3102058 [Patent Document 2] Microfilm of Utility Model Application No. 62-36106 (Utility Model Application No. 63-142214) [Patent Document 3] US Patent Application Publication No. 2018 / 0154741 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the conventional vehicle sunshades described in Patent Documents 1 and 2 above, patterns and text information are printed directly on the surface, and the display effect is limited to the displayed content. If other content is to be displayed, a separate sunshade with different display content printed on it must be prepared, which creates a problem of lacking versatility.

[0009] The sunshade described in Patent Document 3 is something like a folding umbrella with a replaceable flexible layer attached to the front, so if the decorative sheet described in Patent Document 3 is attached to the sunshade of Patent Documents 1 and 2, for example, it would be possible to display various content by displaying letters and pictures on the flexible layer (decorative sheet) and replacing it with a different decorative sheet. Also, if the decorative sheet is small in size, it is easy to print on, which reduces costs and makes it easy to procure. Therefore, the decorative sheet can be formed to a size smaller than the size of the sunshade and attached to the conventional vehicle sunshades of Patent Documents 1 and 2.

[0010] However, since the sunshade is folded like an accordion, it is important to attach the decorative sheet to any position on the car shade so that even when the sunshade is folded, the decorative sheet can be folded along the sunshade and unfolded to its original state when opened.

[0011] Therefore, an object of the present invention is to provide a sunshade for a vehicle that allows a decorative sheet smaller than the base material (sunshade) to be attached to a desired location on the accordion-folded base material. [Means for solving the problem]

[0012] The vehicle sunshade of the present invention is a vehicle sunshade that is placed on the interior side of a vehicle's front windshield, and includes: a plate-shaped base material that is placed on the interior side of the front windshield and is accordion-folded by alternating mountain folds and valley folds along the vertical direction; The present invention is characterized in that it comprises a sheet-like decorative sheet that is arranged on the front surface of the base material so as to be visible from outside the front window and is formed to a size smaller than the base material, the decorative sheet being formed to a size that includes at least one of the valley fold lines and is formed so as to be easily attached and detached to the front surface side of the base material.

[0013] According to the vehicle sunshade of the present invention, the decorative sheet is formed to a size that includes one or more valley fold lines, so when the decorative sheet is folded, the tension in the decorative sheet at the valley fold lines is relaxed. Therefore, even if the base material is mountain-folded at the mountain fold lines and the decorative sheet is pulled in both directions, the decorative sheet located at the valley fold lines will not shift. Therefore, the base material can be folded so that the respective portions divided by the mountain fold lines and the valley fold lines overlap each other.

[0014] The base may include legs that raise the base, and connecting portions that connect the base and the legs. Even if the height of the base material is insufficient for the height of the front windshield, the base material can be raised by the height of the legs, and the height position of the base material becomes higher, so that the vehicle sunshade of the present invention can be supported by being sandwiched between the top surface of the dashboard and the sun visor.

[0015] A recess and a protrusion that fit together may be formed at the lower end of the base and the upper end of the leg. The protrusions of the legs are fitted into the recesses of the base material, which prevents the legs from shifting left and right.

[0016] The connecting portion may include a first connecting portion formed on each of the base material and the leg portion, and a belt-like second connecting portion whose base end is connected to either the base material or the leg portion and extends to the other to connect to the first connecting portion. By connecting to the first connecting part via the second connecting part, the base material and the leg part can be connected simply and firmly.

[0017] The decorative sheet may be provided with an attachment portion for attaching the decorative sheet to the base material, the decorative sheet protruding from a sheet body on which a decorative surface is formed and having a tab portion with a through hole, and the attachment portion may include a first attachment portion formed on the base material and a second attachment portion that joins the first attachment portion to the tab portion via the through hole. By joining the second mounting portion to the first mounting portion formed on the base material via the through-hole of the tab portion, the tab portion is fixed in a state where it is sandwiched between the first mounting portion and the second mounting portion, thereby preventing the tab portion from shifting.

[0018] The tab portion may have a joining portion formed thereon that joins to the first mounting portion. In this way, the joining portion of the tab portion joins to the first mounting portion, and the second mounting portion joins to the first mounting portion while sandwiching the tab portion, thereby enabling the tab portion to be easily and firmly fixed to the base material. [Effects of the Invention]

[0019] According to the vehicle sunshade of the present invention, the portions divided by the mountain fold lines and valley fold lines of the base material can be folded so that they overlap each other, so that a decorative sheet smaller than the base material can be attached to the desired location of the accordion-folded base material.

[Figure 5] FIG. 10 is a diagram showing a sunshade for an automobile according to a second embodiment of the present invention. [Figure 6] FIG. 6 is a partially enlarged view for explaining a connecting portion of the sunshade for an automobile shown in FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0021] (Embodiment 1) Hereinafter, an automobile sunshade as an example of a vehicle sunshade according to Embodiment 1 of the present invention will be described with reference to the drawings. In this specification, the up-down direction will be described with the sun visor side of the automobile sunshade as the top and the dashboard side as the bottom, based on the state in which the automobile sunshade is attached to the windshield.

[0022] The automobile sunshade 1 shown in Figure 1 is intended to be placed on the inside of the vehicle's front windshield, and is installed by leaning it against the top of the dashboard, supporting it on the sun visor, or attaching it to the windshield with a suction cup (not shown).

[0023] The sunshade 1 for an automobile includes a base material 10, a decorative sheet 20, and an attachment portion 30. The base material 10 is disposed inside the front window and is formed in a plate shape. The base material 10 has a predetermined thickness and is made of flexible foamed plastic insulation material, with aluminum sheets vapor-deposited on both sides to function as heat shielding materials. The base material 10 widens downward on both the left and right sides, and the lower edge is formed in an arc shape. The outline of the base material 10 is formed to match or closely match the outline of the windshield, thereby achieving heat shielding and insulation effects.

[0024] The materials applicable to the substrate are not limited to those mentioned above, and any known material having heat-shielding and / or heat-insulating effects can be used. The substrate may be made of only a heat-insulating material, or may be made of only a heat-shielding material. In addition, a rectangular notch 11 is formed in the center of the upper edge of the base material 10, which prevents interference with the rearview mirror of the vehicle on which the vehicle sunshade 1 is installed.

[0025] Mountain fold lines L1 and valley fold lines L2 are alternately formed in the base material 10 along the vertical direction, and by folding it like an accordion, it can be stored compactly. In the present embodiment 1, the base material 10 is divided into eight members in the width direction F1 (left-right direction) by four mountain fold lines L1 and three valley fold lines L2.

[0026] The base material 10 has insertion grooves 12 (see FIG. 3) for arranging the mounting parts 30 at positions where the decorative sheet 20 is attached. In the base material 10 shown in FIG. 1, these are the positions where the rectangular decorative sheet 20 is attached, and are formed at the four corners of the decorative sheet 20. The insertion groove 12 (first insertion groove 12a, second insertion groove 12b) is formed as a pair of parallel linear through holes (see FIG. 4).

[0027] The decorative sheet 20 is a flexible sheet material made of rectangular tarpaulin. The decorative sheet 20 is attached to the base material 10 at approximately the center in the height direction F2, and is formed to a size that spans two of the four members on either side of the valley fold line (center line Lc) located at the center in the width direction F1.

[0028] As shown in Figure 2, the decorative sheet 20 comprises a sheet body 21 on which a decorative surface such as an advertisement is formed, and tab portions 22 protruding laterally from the four corners of the sheet body 21, which are used to attach the substrate 10.

[0029] In this embodiment, tarpaulin is used as the sheet material for the decorative sheet 20. Tarpaulin is a sheet material made of cloth or fabric coated with vinyl chloride resin, and is advantageous in terms of physical strength, water resistance, oil and chemical resistance, stain resistance, weather resistance, heat resistance, and durability. Furthermore, it is resistant to fading when printed, and has advantageous color development properties, making it possible to achieve a high decorative effect. In this embodiment, for example, as shown in Fig. 1, an advertisement for a real estate company is printed on the front surface (attachment surface) of the decorative sheet 20, and by installing the car sunshade 1 of this embodiment with the decorative sheet 20 attached on the front window inside the car, it can function as an advertising and promotion function for the real estate company. For example, in sales by car, by using the car sunshade 1 of this embodiment while the car is parked, it is possible for the salesperson to advertise and promote the car while selling to customers. Therefore, it is possible to enhance the effectiveness of advertising.

[0030] The content printed on the decorative sheet 20 is not limited to company advertisements; for example, it is possible to print a message stating that construction work is underway and place it on the front window of a construction vehicle to alert passersby that construction work is underway. In addition, when restricting a portion of a lane for automobile traffic to carry out construction work, accident response, etc., it is possible to print and display information such as the lane restrictions being in place, and to prompt drivers of moving automobiles to, for example, change lanes. It is also possible to print and display information directing people to the venues of events such as the Olympic and Paralympic Games and concerts. Furthermore, depending on the user's preference, the decorative effect can be enhanced by printing, for example, photographed images or illustrations. Note that materials other than tarpaulin may also be used as the sheet material for the decorative sheet 20. Furthermore, in this embodiment, printing is applied only to the front surface of the decorative sheet 20, but printing may also be applied to the back surface, and either the front or back surface of the decorative sheet 20 may be selected as the front surface depending on the situation and attached to the base material 10.

[0031] The tab portion 22 is formed in a rectangular shape and includes a first region 22A located on the distal end side and having a plurality of through holes 22a formed therein, and a second region 22B located on the proximal end side and having a joining portion 22b formed therein for joining to a first mounting portion (described later). The width of the tab portion 22 is formed so that it can be inserted into the insertion groove 12 formed in the base material 10 .

[0032] As shown in Figure 3, the mounting portion 30 includes a first mounting portion 31 formed in a ring shape so as to wrap around the substrate 10 sandwiched between a pair of insertion grooves 12, and a second mounting portion 32 joined to the first mounting portion 31 via the tab portion 22 of the decorative sheet 20. The first attachment portion 31 and the second attachment portion 32 can be hook-and-loop fasteners. For example, when the first attachment portion 31 is either a male member or a female member, the second attachment portion 32 is the other member. In the first embodiment, the first attachment portion 31 is a female member and the second attachment portion 32 is a male member. Therefore, the joining portion 22b of the decorative sheet 20 is formed by the same male member as the second attachment portion 32, which is the other member. The first attachment portion 31 is formed by forming one female member into a ring and bonding the end faces that are butted together. The second attachment portion 32 may be a male member formed into a substantially square shape.

[0033] The use of the sunshade 1 for an automobile according to the first embodiment of the present invention configured as above will now be described with reference to the drawings. When attaching the decorative sheet 20 to the base material 10 of the automobile sunshade 1 shown in Figure 1, the tab portion 22 is inserted into the insertion groove 12 (insertion groove 12b in the example of Figure 3) located on the outer side from the center of the decorative sheet 20 out of the pair of insertion grooves 12 shown in Figure 3, and the first region 22A is pulled out to the back side of the base material 10. Next, the joining portion 22b (male member) formed in the second region 22B is joined to the first mounting portion 31 (female member). Then, with the first region 22A drawn out to the back side of the base material 10 pressed against the first mounting portion 31, the second mounting portion 32 (male member) is pressed so as to sandwich the tab portion 22. By doing so, the protrusion of the second mounting portion 32 is inserted into the through-hole 22a formed in the first region 22A of the tab portion 22 and entangled with the first mounting portion 31, thereby joining them together. In this way, the second attachment portion 32 is joined to the first attachment portion 31 while sandwiching the tab portion 22, thereby preventing the decorative sheet 20 from shifting.

[0034] In this way, the second region 22B of the tab portion 22 is joined to the first mounting portion 31 attached to the substrate 10 by the joining portion 22b formed on the tab portion 22, and the first region 22A is joined to the first mounting portion 31 by the second mounting portion 32 via the through hole 22a formed in the first region 22A. Therefore, the tab portion 22 protruding from the sheet body 21 can be easily and firmly fixed to the substrate 10.

[0035] By attaching the four tab parts 22 of the decorative sheet 20 to the base material 10 in order using this procedure, the decorative sheet 20 can be attached to the base material 10 in a taut state in a short time without being wrinkled or folded and without being displaced. Furthermore, since the attachment portion 30 is formed by a hook-and-loop fastener, the decorative sheet 20 can be easily removed from the base material 10.

[0036] When the automobile is being driven, the automobile sunshade 1 is folded and stored. As shown in FIG. 4, when folding the sunshade 1 for a vehicle, the sunshade 1 for a vehicle can be deformed into a compact size by folding it in an accordion-like manner with the mountain fold line L1 positioned as a ridge line and the valley fold line L2 positioned as a valley line. For example, if the decorative sheet is positioned so that it spans only one mountain fold line, the sheet body 21 is pulled in both directions around the mountain fold line L1, but since the sheet body 21 is difficult to stretch, folding the base material 10 at the mountain fold line L1 is hindered. However, since the decorative sheet 20 according to this embodiment 1 is formed to a size that includes two valley fold lines L2, when the sheet body 21 is folded, the tension in the sheet body 21 at the position of the valley fold lines L2 is relaxed. Therefore, even if the base material 10 is mountain-folded at the mountain fold line L1 and the main sheet body 21 is pulled in both directions, the main sheet body 21 located at the valley fold line L2 is shifted. Therefore, the base material 10 can be folded so that the portions divided by the mountain fold line L1 and the valley fold line L2 overlap each other.

[0037] In this embodiment 1, the decorative sheet 20 is placed in the center of the base material 10, but a decorative sheet 20 smaller than the base material 10 can be attached to any desired location, such as the upper left, lower right, or a range that includes one or more valley fold lines L2 when viewed from the front of the vehicle. Therefore, the sunshade 1 for automobiles can attach the decorative sheet 20, which is smaller in size than the base material 10, to a desired location on the base material 10 that is folded in an accordion-like manner.

[0038] In this embodiment 1, as shown in FIG. 3, the tab portion 22 is inserted into the insertion groove 12 formed in the base material 10, and the first mounting portion 31 and the second mounting portion 32 are joined on the back side of the base material 10, so that the joined portion cannot be seen from the front side, resulting in a good appearance. However, if there is no problem even if the joined portion is visible from the front surface side, the tab portion 22 may be extended in the surface direction of the front surface and joined by being sandwiched between the first mounting portion 31 and the second mounting portion 32. In this case, the insertion groove 12 can be omitted.

[0039] (Embodiment 2) A sunshade for an automobile according to a second embodiment of the present invention will be described with reference to the drawings. In Fig. 5, the same components as those in Figs. 1 to 4 are designated by the same reference numerals and will not be described. The automobile sunshade of embodiment 2 is designed to be raised by legs and sandwiched between the top of the dashboard and the sun visor so that it can be supported when its height is lower than that of the windshield and it cannot be supported between the top of the dashboard and the sun visor.

[0040] As shown in FIG. 5, the sunshade 1′ for an automobile is formed with a connecting portion 50 that connects the base material 10′ and the leg portion 40. The leg portion 40 is connected to the base material 10' to increase the height of the automobile sunshade 1'. The lower end side 40b of the leg portion 40 is formed in, for example, an arc shape. The leg 40 has an upper end 40t formed with a protrusion 41 that protrudes upward. A recess 13 that opens downward is formed in the lower end 10b of the base material 10'. This recess 13 is formed at a position corresponding to the protrusion 41 of the leg portion 40. A recess 13 formed on the lower end 10b of the base material 10' and a protrusion 41 formed on the upper end 40b of the leg 40 are fitted together.

[0041] The connecting portion 50 includes a first connecting portion 51a formed on the substrate 10' side and a second connecting portion 51b formed on the leg 40 side, and a second connecting portion 52 whose base end is connected to the substrate 10' side, extends toward the leg 40 side, and is connected to the first connecting portions 51a and 51b.

[0042] One of the first connecting portions 51a is formed on the edge portion above the recessed portions 13 of the base material 10′. Also, one of the first connecting portions 51a is formed between the recessed portions 13. The other first connecting portion 51b is formed at the position of the convex portion 41 and at the position of the lower edge of the concave portion formed between the convex portions 41. The first connecting portions 51a, 51b can be, for example, hook-and-loop fasteners having the same configuration as the first attachment portion 31 shown in Fig. 3. Furthermore, the first connecting portions 51a, 51b can be configured to be wound between a pair of insertion grooves 12 formed in the base material 10', or they can be configured to have hook-and-loop fastener pieces attached to the front surface of the base material 10'.

[0043] The second connecting portion 52 may be a hook and loop fastener formed in a belt shape. When either the first connecting portions 51a, 51b or the second connecting portion 52 is a male member, the other connecting portion can be a female member.

[0044] The use of the sunshade 1' for an automobile according to the second embodiment of the present invention configured as above will be described with reference to the drawings. First, as shown in Figure 5, when attaching the automobile sunshade 1' to the front window, the height of the base material 10' may be insufficient, and even when placed on the top surface of the dashboard, it may not reach the sun visor and may not be able to support it.

[0045] In such a case, the legs 40 shown in Figures 5 and 6 are connected to the lower end of the base 10'. When connecting the leg 40 to the lower end of the base material 10', first, the convex portion 41 of the leg 40 is fitted into the concave portion 13 of the base material 10'. This prevents the leg 40 from shifting in the width direction F1 (left-right direction). Next, the tip of the belt-shaped second connecting portion 52 is extended toward the leg portion 40. Then, the second connecting portion 52 is pressed against one of the first connecting portions 51a and the other of the first connecting portions 51b to connect them. Because the second connecting portion 52 can be easily and securely connected to the first connecting portions 51a and 51b, it is possible to prevent the leg portion 40 from coming off or shifting when fitting it into the front window.

[0046] In this way, the base material 10' can be raised by the height of the legs 40, and the height position of the base material 10' becomes higher, so that the automobile sunshade 1' can be supported by being sandwiched between the top surface of the dashboard and the sun visor.

[0047] The height of the legs 40 can be determined as appropriate depending on the height of the base material 10' and the vehicle model. In this way, because the height can be adjusted using the legs 40, if only one type of base material 10' is produced, multiple types of legs 40 can be prepared to accommodate a variety of vehicle models.

[0048] In the second embodiment, the base material 10' side is the recess 13 and the leg portion 40 side is the protrusion 41, but the base material 10' side may be the protrusion and the leg portion 40 side may be the recess. In addition, the second connecting portion 52 is formed so that its base end is connected to the base material 10' side and extends toward the leg portion 40 side, but it may also be formed so that its base end is connected to the leg portion 40 side and extends toward the base material 10' side.

[0049] The above has described the present embodiments 1 and 2. According to the present embodiment, the decorative sheet 20 is made of tarpaulin, which is excellent in durability and has good color development, making it possible to achieve a high decorative effect.

[0050] Furthermore, in this embodiment, a hook-and-loop fastener unit is used as the fixing band, but this is not limiting and other fastening means may be used, such as a belt-like string or a rubber band. In this case, for example, the detachable joining means may be realized by fastening with a snap button or a hook. Also, one end may be fixed to the base material and the other end may be detachable.

[0051] In this embodiment, an example in which the device is installed on the front window of a car has been described, but the device may also be applied to vehicles other than cars, and can be applied to any type of vehicle, such as a work vehicle, heavy machinery, a bus, or a train.
