[0002] A pop-up roof device that is provided on the roof of a vehicle is known. For example, Patent Document 1 describes a pop-up roof device that includes a top cover that opens and closes an opening formed in the roof, and a flexible tent member that is provided between the roof and the top cover, and that is in a stretched state surrounding an expanded space between the roof and the top cover when the top cover is open, and is in a stored state stored inside the top cover when the top cover is closed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3004527 Summary of the Invention [Problem to be solved by the invention]

[0004] The top cover of Patent Document 1 opens and closes the opening based on the raising and lowering of the tip side, with the base end as the pivot point. This has the advantage of simplifying the opening and closing mechanism of the top cover compared to raising and lowering the entire top cover. However, because the pivot point is the rear end of the roof, the roof only opens at an angle toward the front, and an expansion space of uniform height cannot be obtained in the longitudinal direction (front-to-back direction) of the roof, which may limit the uses of the expansion space. [Means for solving the problem]

[0005] The present invention has been made in view of the above-mentioned circumstances and with the objective of solving these problems. The invention of claim 1 is a pop-up roof device provided on the roof of a vehicle, comprising: a top cover that opens and closes an opening formed in the roof; and a flexible tent member that is provided between the roof and the top cover, and that is in a stretched state surrounding an expansion space between the roof and the top cover when the top cover is in an open state, and is in a stored state stored inside the top cover when the top cover is in a closed state, the top cover has a base end side along one end of the roof in the vehicle width direction, and a tip side along the other end of the roof in the vehicle width direction, and opens and closes the opening based on the raising and lowering of the tip side with the base end side as a pivot point, and the tent member in the stretched state connects the tip side of the top cover and the other end side of the roof in the vehicle width direction, and is stretched in a form along the front-rear direction of the vehicle. In the vehicle, when viewed from the front or rear of the vehicle, the tent member in the stretched state has an overhanging portion that overhangs outward from an imaginary straight line connecting the tip of the top cover and the other end of the roof portion in the vehicle width direction, and further includes a holding member that supports the overhanging portion from inside the tent member and holds the overhanging portion in the overhanging state, the holding member includes a plurality of bracing members that can be connected and separated, and when the bracing members are connected, they are braced between the overhanging portion and the roof portion to hold the overhanging portion in the overhanging state, and when the bracing members are separated, In this state, the protruding state of the overhanging portion is released to allow the top cover to be closed, and the holding member is provided between the strut member and the roof portion, and is equipped with a swinging member that swings and changes shape between a bracing position in which the base end of the strut member is displaced in the bracing direction and a retracted position in which the base end of the strut member is retracted in the opposite bracing direction, and the swinging member maintains the bracing position by the reaction force received from the tent member when the connection point with the strut member exceeds an imaginary straight line connecting the tip end of the strut member and the swing fulcrum of the swinging member. A pop-up roof device. The invention of claim 2 further comprises an elastic member that biases the protruding portion in the storing direction. 1 2 is a pop-up roof device according to the first embodiment. Effect of the Invention

[0006] According to the invention of claim 1, the top cover opens and closes the opening based on the lifting and lowering of the tip side with the base end side along one end of the roof part in the vehicle width direction as a pivot point, so the opening and closing mechanism of the top cover can be simplified compared to when the entire top cover is lifted and lowered. Also, the tent member in the stretched state connects the tip side of the top cover and the other end side of the roof part in the vehicle width direction and is stretched in a form along the front-rear direction of the vehicle, so that an expansion space of uniform height is obtained in the longitudinal direction of the roof part (front-rear direction of the vehicle), and the uses of the expansion space can be expanded. Moreover, When viewed from the front or rear of the vehicle, the tent member in the stretched state has a protruding portion that protrudes outward from an imaginary straight line connecting the tip of the top cover and the other end of the roof portion in the vehicle width direction, thereby widening the expanded space throughout the entire longitudinal direction of the roof portion and further expanding the uses of the expanded space. moreoverSince the tent further includes a retaining member that supports the protruding portion from the inside of the tent member and holds the protruding portion in the protruding state, the tent member can be well maintained in its stretched state. Moreover, The retaining member is provided with a plurality of tension members which can be connected and separated, and when the tension members are connected, they are tensioned between the protruding portion and the roof portion to hold the protruding portion in a protruding state, and when the tension members are separated, the protruding state of the protruding portion is released to allow the top cover to be closed, thereby preventing the retaining members from getting in the way when the top cover is closed. Also moreover The retaining member is provided between the tensioning member and the roof portion, and is equipped with a swinging member that swings and transforms between a tensioning position in which the base end of the tensioning member is displaced in the tensioning direction, and a retracted position in which the base end of the tensioning member is retracted in the opposite tensioning direction, and the swinging member maintains its tensioning position by the reaction force it receives from the tent member when the connection point with the tensioning member crosses an imaginary straight line connecting the tip end of the tensioning member and the swinging fulcrum of the swinging member, so that the swinging member can be held in the tensioning position with a simple configuration that utilizes the so-called fulcrum crossing effect. Also, claims 2 According to this invention, since the tent member is further provided with an elastic member that biases the protruding portion in the storing direction, the operation of storing the tent member inside the top cover becomes easier.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Fig. 1 to Fig. 9, reference numeral 1 denotes a pop-up roof device provided on the roof of a vehicle V, and the pop-up roof device 1 includes a base plate 2, a floor material 3, a top cover 4, a butterfly plate 5, an oil damper 6, a tent member 7, a holding member 8, and an elastic member 9. The vehicle V in this embodiment is a minicar with a one-box, but may also be a regular car with a one-box or a large vehicle. Furthermore, the vehicle is not limited to a one-box, and may be a station wagon, SUV, sedan, truck, or the like.

[0009] After the existing roof of the vehicle V is cut away to create an opening, the substrate 2 is attached to the vehicle V so as to close the periphery of the opening of the cut-out portion, and functions as a reinforcing member for the roof of the vehicle V. As shown in Fig. 8, the substrate 2 is formed into a frame shape from a rigid member, and has a recess 2a on the upper surface that is rectangular in plan view and recessed downward, and in the center of the recess 2a is an opening 2b that is rectangular in plan view and allows people to enter and exit.

[0010] The floor material 3 is configured in the shape of a rectangular board and can be laid across the recess 2a of the base plate 2 so as to cover the opening 2b, forming the floor of the expansion space described later. When the expansion space is used as a sleeping space, the floor material 3 functions as a bed. As shown in FIG. 6, the floor material 3 of this embodiment is composed of multiple divided floor materials 3a, 3b, and 3c arranged in the front-to-back direction. This division type makes it easy to lay and remove the floor material 3. By lifting the top cover 4 described later to open and close the floor material to the side, a uniform height can be ensured from the front to the back, which ensures space in the ceiling area, and by attaching the floor material 3 to the upper space floor, two spaces can be secured, one above the other, ensuring a large living space.

[0011] The top cover 4, which is the roof of the vehicle V, is rotatably supported on the base plate 2 via a plurality of hinge plates 5, and opens and closes the upper surface of the base plate 2 (the recess 2a and the opening 2b) in response to a rotation operation. To be more specific, as shown in Figs. 1 to 5, the top cover 4 is a cover member having a rectangular shape in a plan view, with a base end side along one end (e.g., the right end) in the vehicle width direction of the base plate 2 and a tip end side along the other end (e.g., the left end) in the vehicle width direction of the base plate 2, and opens and closes the upper surface of the base plate 2 to a raised position and a lowered position based on the elevation and lowering of the tip end side with the base end side as a rotation fulcrum. In this embodiment, the rotation angle of the top cover 4 in the open state is set to approximately 45°, but the rotation angle of the top cover 4 in the open state may be changed within a range of 30 to 90°.

[0012] With such a top cover 4, the upper surface of the base plate 2 is opened and closed to a raised position and a lowered position based on the raising and lowering of the tip side, with the base end side along one side end of the base plate 2 in the vehicle width direction as a pivot point. This not only simplifies the opening and closing mechanism of the top cover 4 compared to when the entire top cover 4 is raised and lowered, but also provides an expansion space of uniform height in the longitudinal direction (front-to-back direction) of the roof portion, thereby expanding the uses of the expansion space.

[0013] The oil damper 6 is provided between the base plate 2 and the top cover 4, and assists the opening operation of the top cover 4 by biasing the top cover 4 in the opening direction. In this embodiment, a first oil damper 6 that biases the front side of the top cover 4 and a second oil damper 6 that biases the rear side of the top cover 4 are provided. When the top cover 4 is in the open state, the oil damper 6 is exposed at the front and rear of the top cover 4 in an extended state, but when the top cover 4 is in the closed state, the oil damper 6 is stored inside the top cover 4 in a contracted state.

[0014] The tent member 7 is a flexible sheet material provided between the base plate 2 and the top cover 4. When the top cover 4 is in the open state in the raised position, the tent member 7 is in a stretched state surrounding the expansion space formed around the lower surface between the base plate 2 and the top cover 4. When the top cover 4 is in the closed state in the lowered position, the tent member 7 is in a folded and stored state inside the top cover 4. The tent member 7 in the stretched state connects the tip side (e.g., the left end side) of the top cover 4 and the other end side (e.g., the left end side) in the vehicle width direction of the base plate 2, and is stretched in a form along the front-rear direction of the vehicle V. This provides an expansion space of uniform height in the longitudinal direction of the base plate 2 (front-rear direction of the vehicle), and the uses of the expansion space can be expanded. That is, by making the top cover 4 structured to be opened and closed sideways, when the narrow interior (interior height) of the vehicle V is expanded upward, a uniform interior height can be secured from the front to the rear, so that a person can move in a standing position inside the interior, improving livability.

[0015] 1 and 3, the tent member 7 in the stretched state has a protruding portion 7a that protrudes outward from an imaginary straight line L1 that connects the tip (e.g., the left end) of the top cover 4 and the other end (e.g., the left end) in the vehicle width direction of the base plate 2. Such a protruding portion 7a makes the expanded space wider over the entire longitudinal area of ​​the roof portion, further expanding the uses of the expanded space.

[0016] As shown in Figs. 1 to 3 and 8, the tent member 7 includes a front portion 7b covering the front of the expansion space, a rear portion 7c covering the rear of the expansion space, a side portion 7d covering the other side (e.g., the left side) of the expansion space in the vehicle width direction, and an upper portion 7e covering the upper part of the expansion space. The tent member 7 is configured to have a skirt-like canopy shape with an opening 7g that allows a person to stand on the lower surface surrounded by the front portion 7b, the rear portion 7c, and the side portion 7d, and the peripheral bottom of the opening 7g is fastened to the base plate 2 in a sealed manner. The front portion 7b and the side portion 7d of the tent member 7 are provided with windows 7f. The windows 7f are configured to be covered with a tent curtain member that blocks external light, but when the film member is rolled up, a transparent resin sheet, insect screen, etc. are exposed, allowing lighting and ventilation of the expansion space.

[0017] As shown in Fig. 9, the holding member 8 supports the overhanging portion 7a from the inside of the tent member 7 and holds the overhanging portion 7a in an overhanging state. As shown in Figs. 10 to 14, the holding member 8 of this embodiment includes a plurality of connectable and separable bracing members 81, 82, and when the bracing members 81, 82 are connected, they are capable of bracing between the overhanging portion 7a and the board 2 to hold the overhanging portion 7a in an overhanging state, and when the bracing members 81, 82 are separated, the overhanging state of the overhanging portion 7a is released, allowing the top cover 4 to be closed.

[0018] Specifically, the first tension member 81 is a U-shaped pipe member and includes an action portion 81a that fits along the inside of the top of the protruding portion 7a, and a pair of front and rear extension portions 81b that extend from both ends of the action portion 81a to the diagonal sides of the expansion space. The second tension member 82 is a pair of rod members that can be inserted into and removed from the tips of the pair of front and rear extension portions 81b.

[0019] The holding member 8 further includes a swinging member 83 provided between the second strut member 82 and the base plate 2. The swinging member 83 swings between a bracing position in which the base end of the second strut member 82 is displaced in the bracing direction, and a retracted position in which the base end of the second strut member 82 is retracted in the opposite bracing direction. The swinging member 83 in this embodiment is attached to a bracket 84 fixed to the base plate 2 via a swinging support shaft 85 so as to be swingable in the vehicle width direction, and the base end of the second strut member 82 is connected to the tip end of the swinging member 83 via a connecting shaft 86 so as to be swingable in the same direction as the swinging member 83.

[0020] Fig. 10 shows the holding member 8 in a braced state, and Fig. 11(a) and (b) show the holding member 8 in a separated state. As shown in Fig. 11, when the first bracing member 81 and the second bracing member 82 are separated and the swingable member 83 and the second bracing member 82 are aligned along the upper surface of the substrate 2, the top cover 4 is allowed to be closed. Also, when the top cover 4 is opened from the closed state, the holding member 8 is in the state shown in Fig. 11, and when the holding member 8 is changed from this state to the braced state shown in Fig. 10, the operations shown in Figs. 12 to 14 are performed.

[0021] Fig. 12 shows a first connecting procedure (preparation before connecting) of the holding member 8, Fig. 13 shows a second connecting procedure (connecting) of the holding member 8, and Fig. 14 shows an operation of the swinging member 83 to cross the fulcrum. First, as shown in Fig. 12, the swinging member 83 in the bracing position is swung to stand up toward the retracted position, and then, as shown in Fig. 13, the first and second bracing members 81 and 82 are held by hand and connected to each other. Then, as shown in Fig. 14, when the swinging member 83 is swung from the retracted position to the bracing position, the connecting shaft 86, which is the connecting point between the second bracing member 82 and the swinging member 83, crosses the imaginary straight line L2 connecting the tip of the first bracing member 81 and the swinging fulcrum (swinging shaft 85) of the swinging member 83, and the swinging member 83 is pressed toward the bracket 84 by the reaction force received from the tent member 7, and maintains the bracing position. 12 to 14, the holding member 8 in the tensioned state shown in FIGS. 10 and 14 can be brought into the separated state shown in FIG. 11, and the top cover 4 can be closed.

[0022] The elastic member 9 biases the protruding portion 7a of the tent member 7 in the storing direction. For example, as shown in Fig. 9(b), the elastic member 9 in this embodiment is a rubber band looped around the tent member 7, and pulls the tent member 7 into the inside of the top cover 4 when the top cover 4 is closed. The pulled-in tent member 7 is folded and stored in the space between the top cover 4 and the board 2, as shown in Fig. 9(a).

[0023] The bottom surface of the top cover 4 is provided with a handle 41 to be gripped when opening or closing the top cover 4, and a belt 42 to prevent the stored tent member 7 from protruding. When the top cover 4 is in the closed state, the belt 42 engages with a hook (not shown) provided on the base plate 2 to prevent the stored tent member 7 from protruding. When the top cover 4 is in the closed state, the tent member 7 presses the divided floor members 3a to 3c, preventing rattling during travel. In particular, if the orientation of the middle divided floor member 3b among the three divided floor members 3a to 3c arranged in the front-rear direction is changed from the left-right direction to the front-rear direction and the middle divided floor member 3b is sandwiched between the stored tent member 7 and the other divided floor members 3a and 3c, the pressing force of the tent member 7 on the divided floor members 3a to 3c is increased, and rattling during travel can be more reliably prevented.

[0024] As shown in Fig. 5, when the top cover 4 is lowered into the closed state, it can be closed in accordance with the body lines (design) of the vehicle by fitting closely to the base plate 2, and has a shape that is no different from a normal vehicle design. When driving, it fits closely to the base plate 2, and when stopped for rest, sleeping in the car, camping, teleworking, etc., the top cover 4 is of a side-opening type and can be opened and closed easily by oil dampers 6 arranged at the front and rear, which spring up upward to increase the interior space (interior height) and make the interior space even larger.

[0025] According to this embodiment configured as described above, the pop-up roof device 1 is provided on the roof portion (base plate 2) of a vehicle V, and includes a top cover 4 that opens and closes an opening 2b formed in the base plate 2, and a flexible tent member 7 that is provided between the base plate 2 and the top cover 4 and is in a tensioned state surrounding the expanded space between the base plate 2 and the top cover 4 when the top cover 4 is in an open state, and is in a stored state stored inside the top cover 4 when the top cover 4 is in a closed state. The top cover 4 has a base end side that runs along one end of the base plate 2 in the vehicle width direction, and a tip side that runs along the other end of the base plate 2 in the vehicle width direction, and opens and closes the opening 2b based on the raising and lowering of the tip side with the base end side as a pivot point. Therefore, the opening and closing mechanism of the top cover 4 can be simplified compared to the case where the entire top cover 4 is raised and lowered. Furthermore, the tent member 7 in the stretched state connects the tip side of the top cover 4 and the other end side of the base plate 2 in the vehicle width direction, and is stretched in a manner that follows the fore-and-aft direction of the vehicle V, so that an expanded space of uniform height is obtained in the longitudinal direction of the base plate 2 (the fore-and-aft direction of the vehicle), thereby expanding the uses of the expanded space.

[0026] Furthermore, when viewed from the front or rear of the vehicle, the tent member 7 in the stretched state has a protruding portion 7a that protrudes outward from the imaginary straight line L1 connecting the tip of the top cover 4 and the other end of the base plate 2 in the vehicle width direction, thereby widening the expanded space over the entire longitudinal direction of the base plate 2 and further expanding the uses of the expanded space.

[0027] In addition, the pop-up roof device 1 further includes a retaining member 8 that supports the overhanging portion 7a from inside the tent member 7 and holds the overhanging portion 7a in an overhanging state, so that the tent member 7 can be well maintained in its stretched state.

[0028] In addition, the retaining member 8 is equipped with a plurality of tension members 81, 82 which can be connected and separated. When the tension members 81, 82 are connected, they are tensioned between the protruding portion 7a and the substrate 2 to hold the protruding portion 7a in a protruding state. When the tension members 81, 82 are separated, the protruding state of the protruding portion 7a is released to allow the top cover 4 to be closed, thereby preventing the retaining member 8 from getting in the way when the top cover 4 is closed.

[0029] In addition, the retaining member 8 is provided between the second tension member 82 and the base plate 2, and is equipped with a swinging member 83 that swings and transforms between a tension position in which the base end of the second tension member 82 is displaced in the tension direction, and a retracted position in which the base end of the second tension member 82 is retracted in the opposite tension direction. The swinging member 83 maintains its tension position by the reaction force it receives from the tent member 7 when the connection point with the second tension member 82 crosses the imaginary straight line L2 connecting the tip end of the first tension member 81 and the swing fulcrum of the swinging member 83, so that the swinging member 83 can be held in the tension position with a simple configuration that utilizes the so-called fulcrum crossing effect.

[0030] Moreover, since the pop-up roof device 1 further includes the elastic member 9 that biases the overhanging portion 7a in the storing direction, the operation of storing the tent member 7 inside the top cover 4 becomes easier.

[0031] As described above, according to this embodiment, a roof for an automobile can be provided that has a pop-up roof configuration that is invented and devised to maximize the living space inside the vehicle by modifying a commercially available standard one-box type automobile, and can be used for overnight stays in cars, camping cars, mobile sales cars, mobile office cars (telework cars, remote work cars), etc. The top cover described in this embodiment can be made of, for example, an FRP roof material, and the base plate 2 can also be made of a double structure made of FRP, which can improve the heat insulation effect. This has the advantage of improving the efficiency of the in-house cooler and heater. In addition, the sound of rain hitting the top cover 4 during heavy rain can be reduced compared to a top cover made of steel plate. [Explanation of symbols]
