Description

[Technical Field]

[0001] The present invention relates to a shutter device provided in a roof space formed between a main body roof that forms the roof of a vehicle body and a retractable roof that is raised from the main body roof, and to a vehicle equipped with the shutter device. [Background technology]

[0002] Conventionally, vehicles such as campers have been known that are equipped with a retractable roof that can be raised and lowered relative to the main roof. For example, Patent Document 1 discloses a camper with a rectangular opening formed in the main roof, and a retractable roof that is slightly larger than the opening and can be raised and lowered freely by a link mechanism.

[0003] When not in use, the retractable roof is lowered until its periphery meets the main roof, closing the opening. When the retractable roof is raised, it covers the top of the opening while maintaining a certain distance, creating a roof space between the main roof and the retractable roof that expands the interior space of the vehicle.

[0004] Such retractable roofs have long been in high demand for outdoor leisure activities because they provide a sense of openness and ventilation. In addition, as working styles have become more diverse in recent years, camper vans with retractable roofs are gaining attention as a form of workplace. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-117555 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the camper disclosed in Patent Document 1 has a problem in that noise from outside the vehicle enters the interior of the vehicle, since the exterior of the vehicle is separated from the roof space by only a single flexible sheet.

[0007] In particular, when a vehicle is used as a work space, soundproofing measures are desired when the retractable roof is in use to create a more comfortable space.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a shutter device that suppresses the intrusion of noise from outside the vehicle even when the retractable roof is in use, and a vehicle equipped with the shutter device. [Means for solving the problem]

[0009] As a means for solving the above problems, the shutter device and the vehicle equipped with the shutter device of the present invention take the following measures.

[0010] That is, the first aspect of the present invention is a shutter device installed in the roof space formed between a main roof that forms the roof of a vehicle body and a retractable roof that is raised from the main roof. The shutter device has a sound-insulating cover part that is installed to cover the roof space from the outside of the vehicle, and a locking part that detachably locks the cover part to the retractable roof and / or the main roof.

[0011] According to the first aspect of the present invention, by using a shutter device in the roof space, the soundproof cover acts as a partition between the outside of the vehicle and the roof space, making it possible to suppress the intrusion of noise from outside the vehicle.

[0012] A second aspect of the present invention is the above-mentioned first aspect, wherein the locking portion is locked to an upper flange portion that protrudes in a downwardly bending manner from the peripheral edge of the top plate portion of the lift-up roof.

[0013] According to the second aspect of the present invention, the cover portion can be positioned at the outermost side of the roof space, thereby making the roof space feel larger and more open.

[0014] A third aspect of the present invention is the connector according to the second aspect, wherein the locking portion is a fitting portion that can be fitted onto a lower edge portion of the upper flange portion.

[0015] According to the third aspect of the present invention, the mechanical locking is achieved by utilizing the shape of the lower edge portion, and therefore the attachment strength can be increased compared to when the locking is achieved by, for example, a magnet or hook-and-loop fastener.

[0016] A fourth aspect of the present invention is the above-mentioned third aspect, wherein the cover portion is made of a panel material.

[0017] According to the fourth aspect of the present invention, the sound insulation is superior to that of cloth, tent fabric, etc., and the intrusion of noise from outside the vehicle can be further suppressed.

[0018] A fifth aspect of the present invention is the fourth aspect of the present invention, wherein the main body roof has a lower flange portion that rises from the entire periphery of the vehicle body, and the four corners of the upper edge of the lower flange portion are rounded. The liftable roof rises and falls parallel to the main body roof, and the upper flange portion protrudes from the entire periphery of the rectangular top plate portion, and the four corners of the lower edge portion are rounded. The fitting portion is formed integrally with the panel material and fits slidably with the upper edge portion and the lower edge portion along the circumferential direction in which each edge extends. The cover portion is composed of a plurality of rectangular panel materials whose adjacent long sides are connected by hinges so that the fitting portion can slide along the rounded corners of the edges of the upper flange portion and the lower flange portion.

[0019] According to the fifth aspect of the present invention, the roof space can be covered by holding the edge of the covering portion and sliding it, which simplifies the installation work compared to installing each piece individually. In addition, since the hinges allow the covering portion to be folded freely, it can be rolled up and stored compactly when not in use.

[0020] A sixth aspect of the present invention, in the fifth aspect, includes a shutter body having the cover portion and the fitting portion, and a storage portion that winds up the shutter body unfolded in a sheet shape into a roll and stores the rolled up shutter body so that it can be pulled out in sheet form. The storage portion has a fixing portion that can fix the shutter body stored in a roll shape to the upper flange portion and / or the lower flange portion in a state where the axial direction of the shutter body stored in a roll shape is aligned with the up and down direction in which the liftable roof rises and falls.

[0021] According to the sixth aspect of the present invention, if the storage section is fixed to the upper flange section or the lower flange section, there is no need to support the shutter body, so the installation work can be done by one person. If there is no storage section, at least two people are required to work together: one to support the shutter body and one to install it.

[0022] A seventh aspect of the present invention is a vehicle equipped with the shutter device according to any one of the first to sixth aspects, wherein the shutter device covers from the outside a built-in tent portion that covers the roof space.

[0023] According to the seventh aspect of the present invention, when using the roof space, the tent portion and the shutter device can be selectively used, thereby providing the user with a more comfortable vehicle interior space. [Brief explanation of the drawings]

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, directions such as front, back, up, down, left, and right refer to the directions shown in each drawing. In the following description, when a specific reference drawing is not shown or when there is no reference symbol corresponding to a reference drawing, any of Figures 1 to 9 will be referred to as appropriate.

[0026] (Camper 4 Overview) As shown in Figure 1, the camper van 4 is equipped with what is called a pop-up roof. A pop-up roof is a device that mounts a roof on the vehicle body and lifts the roof up to increase the interior space.

[0027] Specifically, the camper 4 has a main roof 5 that forms the roof of the vehicle body, and a lift-up roof 6 that can be raised and lowered relative to the main roof 5. A link mechanism 8 is provided between the main roof 5 and the lift-up roof 6, and the link mechanism 8 allows the lift-up roof 6 to move vertically in parallel with the main roof 5.

[0028] 1 and 4, the lift-up roof 6 is composed of a rectangular top plate portion 63 and an upper flange portion 61 that bends downward from the periphery of the top plate portion 63. The upper flange portion 61 has a rectangular lower edge portion 62, and the four corners (each corner portion 6a) of the lower edge portion 62 are rounded.

[0029] As shown in FIG. 4, the retractable roof 6 enables the interior space of the camper van 4 to be expanded. In other words, when the retractable roof 6 is raised from the main roof 5, the ceiling of the camper van 4 becomes higher by that amount, and a roof space 9 is formed. The roof space 9 is a new space formed between the main roof 5 and the retractable roof 6. The user can use the roof space 9 to make the interior space larger than when the retractable roof 6 is not used.

[0030] As shown in Figure 5, when the retractable roof 6 is not in use, it is lowered until it meets the main roof 5. The main roof 5 has a lower flange portion 51 that extends up from the entire periphery of the camper van 4. The lower flange portion 51 has an upper edge portion 52 that is rectangular, similar to the lower edge portion 62 of the upper flange portion 61, and the four corners (each corner portion 5a) of the upper edge portion 52 are rounded. The lower edge portion 62 of the upper flange portion 61 of the retractable roof 6 is closed so that it abuts against the upper edge portion 52 of the lower flange portion 51.

[0031] The camper van 4 also has a built-in tent section 7. The tent section 7 is cylindrical and covers the roof space 9. The tent section 7 is made of a flexible material so that it can be folded and unfolded in accordance with the vertical movement of the retractable roof 6. As a result, it has low sound insulation, and while using the retractable roof 6 allows for more space in the cabin, it also causes the problem of outside noise entering the cabin.

[0032] (Outline of shutter device 1) The shutter device 1 is used as a soundproofing measure when the retractable roof 6 is raised in the camper van 4 described above. As shown in Fig. 2, when the shutter device 1 is set on the camper van 4, the roof space 9 is doubly covered together with the tent section 7. The shutter device 1 has higher sound insulation properties than the tent section 7, and suppresses the intrusion of noise outside the vehicle.

[0033] As shown in Figure 2, the shutter device 1 is composed of a shutter main body 2 that covers the roof space 9 from the outside of the tent part 7, and a storage part 3 that stores and removes the shutter main body 2. The storage part 3 can be fixed to the camper van 4 by utilizing the structure of an upper flange part 61 and a lower flange part 51.

[0034] Specifically, as shown in Fig. 3, the storage section 3 is fixed to the notches 64 provided in the upper flange section 61 and the lower flange section 51. The shutter main body 2 pulled out from the opening 33 of the storage section 3 is deployed along the edges 52, 62 of the upper flange section 61 and the lower flange section 51. With such a storage section 3, the deployment work of the shutter main body 2 can be done by one person. If the storage section 3 were not present, the shutter main body 2 would have to be deployed along the edges 52, 62 while being supported, which would require at least two people.

[0035] When deploying the shutter main body 2, the user can arbitrarily determine the range over which the shutter main body 2 covers the roof space 9. As shown in FIG. 2, it may cover part of the roof space 9, or it may cover the entire roof space 9. Two shutter devices 1 are used to cover the roof space 9. Specifically, one shutter device 1 is set on the left side of the vehicle, and the other on the right side of the vehicle. Dividing the shutter device 1 into two in this way reduces the weight, making it easier to carry and handle.

[0036] (Details of the shutter device 1) As shown in Figure 6, the shutter device 1 is made up of a shutter main body 2 and a storage section 3. The shutter main body 2 has a cover section 21 that covers the roof space 9 from the outside of the camper van 4, and a fitting section 22 that detachably fastens the cover section 21 to the main roof 5 and the retractable roof 6.

[0037] As shown in Figures 6 to 8, the cover 21 is configured by wrapping rod-shaped slats 2a arranged in parallel at regular intervals in two flexible sheets 2b, one on the front and one on the back. Each slat 2a is made, for example, by injection molding resin, and has a U-shaped upper and lower end so that it can fit into the edges 52, 62 of the lower flange 51 and the upper flange 61. The upper and lower ends of these slats 2a are arranged in parallel at regular intervals to form the fitting portion 22 of the shutter main body 2.

[0038] 8, if you look closely at the space between adjacent slats 2a in the cover 21, you will see that there is a section where only the sheet 2b is present. This section functions as a hinge 2c, and this hinge 2c allows the shutter body 2 to be rolled up like a shutter-type bathtub cover, allowing it to be stored compactly in the storage section 3, which will be described later.

[0039] With the above-described configuration, the shutter main body 2 is fitted to the lower flange portion 51 and the upper flange portion 61 so as to be slidable in the circumferential direction in which the edges 52, 62 extend. When the shutter main body 2 is slid along the edges 52, 62, it eventually comes across the rounded corners 5a, 6a. Here, the adjacent long sides of the slats 2a are connected by hinges 2c, making them bendable, so the shutter main body 2 can slide along the corners 5a, 6a.

[0040] As shown in FIGS. 6 and 9, the storage section 3 winds up the shutter body 2 unfolded in a sheet shape into a roll, and stores the shutter body 2 wound up in a roll so that it can be pulled out in a sheet shape.

[0041] The storage section 3 is made up of a housing large enough to enclose the roll-shaped shutter main body 2. The housing is, for example, a rectangular box shape and is equipped with a knob 31, a notch 32, an opening 33, a fastener 34, and a hook-and-loop fastener 35. Since the storage sections 3 of the two shutter devices 1 set in the camper 4 have a symmetrical structure, the storage section 3 fixed to the left side of the vehicle will be explained as a representative example.

[0042] The knob 31 is used to turn the shaft 3a inside the housing. The end of the shutter main body 2 is connected to the shaft 3a. When the knob 31 is turned, the shutter main body 2 is wound around the shaft 3a, and the shutter main body 2 can be wound up in a roll.

[0043] The notches 32 are provided on both the top and bottom surfaces of the housing, and are formed so that they can fit into the portions where the notches 64 are provided on the edges 52, 62 of the lower flange portion 51 and the upper flange portion 61. The notches 32 are cut deeper on the top surface than on the bottom surface, so that the storage section 3 can be fixed to the notches 64 of the camper van 4 in the same way as fitting a screen door into a window frame. After fixing, the shutter body 2 stored in a roll form in the storage section 3 has its axial direction aligned with the vertical direction in which the retractable roof 6 rises and falls.

[0044] The opening 33 is provided on the side of the housing and functions as an entrance / exit for the shutter main body 2. The opening 33 is provided in a straight line passing through the notch 32 on the upper surface side and the notch 32 on the lower surface side. Therefore, as shown in FIG. 3, when the storage section 3 is fixed to the camper van 4, the opening 33 is positioned so as to face the circumferential end portions 6b of the edges 52, 62 formed by the notches 64.

[0045] The fastener 34 is provided on the side of the storage section 3. When the shutter main body 2 is stored in the storage section 3, the operating part 2d provided on the end of the shutter main body 2 protrudes from the opening 33. The fastener 34 is used to hook the operating part 2d and perform terminal processing.

[0046] The hook and loop fastener 35 is provided on the side of the storage section 3. The hook and loop fastener 35 allows the two shutter devices 1 to be bundled together as a set, making them easier to carry and handle.

[0047] To summarize the above, the shutter device (1) according to this embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0048] That is, the shutter device (1) is provided in a roof space (9) formed between a main roof (5) that forms the roof of the vehicle body and a retractable roof (6) that is raised from the main roof (5). The shutter device (1) has a sound-insulating cover part (21) that is provided to cover the roof space (9) from the outside of the vehicle, and a locking part (22) that detachably locks the cover part (21) to the retractable roof (6) and / or the main roof (5).

[0049] According to the above configuration, by using the shutter device (1) in the roof space (9), the sound-insulating cover portion (21) acts as a partition between the outside of the vehicle and the roof space (9), thereby suppressing the intrusion of noise from outside the vehicle.

[0050] The locking portion (22) is locked to an upper flange portion (61) that bends downward and protrudes from the peripheral edge of the top plate portion (63) of the lift-up roof (6).

[0051] According to the above configuration, the cover portion (21) can be positioned at the outermost side of the roof space (9), so that the roof space (9) can be made larger and more open.

[0052] The locking portion (22) is a fitting portion (22) that can be fitted to the lower edge portion (62) of the upper flange portion (61).

[0053] According to the above-described configuration, the shape of the lower edge (62) is utilized to mechanically lock the device, and therefore the attachment strength can be increased compared to when the device is locked using, for example, a magnet or hook-and-loop fastener.

[0054] The cover portion (21) is made up of a panel material (2a).

[0055] According to the above configuration, the sound insulation is superior to that of cloth, tent fabric, etc., and the intrusion of noise from outside the vehicle can be further suppressed.

[0056] The main roof (5) has a lower flange (51) that extends up from the entire periphery of the vehicle body, with the four corners of the upper edge of the lower flange (51) being rounded, and the liftable roof (6) rises and falls parallel to the main roof (5), with an upper flange (61) that protrudes from the entire periphery of a rectangular top plate (63) and has four corners of a lower edge (62) that are rounded. The fitting portion (22) is formed integrally with the panel material (2a) and fits slidably with the upper and lower edge portions (62) along the circumferential direction in which each edge extends, and the cover portion (21) is composed of a plurality of rectangular panel materials (2a) whose adjacent long sides are connected by hinges (2c) so that the fitting portion (22) can slide along the rounded corners (5a) of each edge of the upper flange portion (61) and the lower flange portion (51).

[0057] According to the above configuration, the roof space (9) can be covered by holding the edge of the cover portion (21) and sliding it, which simplifies the installation work compared to installing each piece individually. In addition, since the cover portion (21) can be folded freely by the hinges (2c), it can be rolled up and stored compactly when not in use.

[0058] The shutter device (1) also has a shutter body (2) having a cover portion (21) and a fitting portion (22), and a storage portion (3) that winds up the shutter body (2) unfolded in a sheet shape into a roll and stores the rolled up shutter body (2) so that it can be pulled out in sheet form. The storage portion (3) has a fixing portion (32) that can be fixed to the upper flange portion (61) and / or the lower flange portion (51) with the axial direction of the shutter body (2) stored in a rolled shape aligned with the vertical direction in which the lift-up roof (6) rises and falls.

[0059] According to the above configuration, if the storage section (3) is fixed to the upper flange section (61) or the lower flange section (51), there is no need to support the shutter body (2), and therefore the installation work can be done by one person. If there were no storage section (3), at least two people would be required to work together: one to support the shutter body (2) and one to install the shutter body (2).

[0060] In addition, in a vehicle (4) equipped with the shutter device (1), the shutter device (1) covers from the outside a built-in tent portion (7) that covers the roof space (9).

[0061] According to the above configuration, when using the roof space (9), the tent portion (7) and the shutter device (1) can be selectively used, thereby providing the user with a more comfortable vehicle interior space.

[0062] Other Embodiments Although one embodiment of the present invention has been described above, the present invention can be embodied in various forms other than the above embodiment.

[0063] 1. In the above embodiment, the shutter device is composed of a shutter body and a storage section, but the storage section may be eliminated and the shutter device may consist of only the shutter body. In that case, various forms of the shutter body as the shutter device other than those in the above embodiment are also possible.

[0064] In other words, the covering portion may be any material that has sound insulation properties and is provided to cover the roof space from the outside of the vehicle, and may be, for example, a soundproof fabric such as a soundproof curtain. It may also be four panels that cover the roof space from the front, back, left, and right. The size and shape of these fabrics and panels are designed appropriately depending on the roof space.

[0065] The fitting portions do not need to be slidable along the flanges, and may simply be fitted together in a detachable manner. For example, each flange may have a plurality of holes, and the cover may have projections corresponding to the holes, so that they can be fitted together and detached.

[0066] Furthermore, any configuration is acceptable as long as the cover can be detachably fastened to the lift-up roof and / or main roof. If the cover is made of the sound-insulating fabric described above, for example, a magnet or hook-and-loop fastener may be attached to the fabric, and a metal or hook-and-loop fastener may be provided only on the lift-up roof to attach the two together.

[0067] 2. In the above embodiment, the fitting portion is fitted to the upper flange portion, but it may be fitted to the top plate portion. For example, a protrusion for fitting the fitting portion may be provided on the back surface of the top plate portion. In that case, the shutter body may cover the roof space from the inside of the tent portion.

[0068] 3. In the above embodiment, it was explained that when the storage section is fixed to each flange section, the opening is conveniently positioned, and the shutter body pulled out from the opening is then slidably fitted onto each edge of each flange section. However, the storage section may be fixed to each flange section with the axial direction of the stored roll-shaped shutter body aligned with the vertical direction in which the lift-up roof rises and falls, and the storage section may be one that requires vertical alignment of the shutter body after fixing.

[0069] 4. In the above embodiment, the shutter body is divided into two parts and two shutter devices are used to cover the roof space, but it is also possible to store enough shutter bodies to cover the roof space in a storage section and set one shutter device on the camper van.

[0070] 5. In the above embodiment, the storage unit is fixed to the lower flange portion and the upper flange portion by a notch provided in the housing of the storage unit, but it may also be fixed in another way, such as by attaching it with a magnet or by hooking it with a hook.
