Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, a special-purpose vehicle dispatched to the disaster site may have a heavy structure like that in Patent Document 1 without any problem, but it is not a vehicle that can be easily driven by the general public. However, even for the general public, if they can possess a movable body whose space can be expanded, reduced, and varied, they can secure a large interior space at the destination. For this purpose, it is desirable to have a movable body with a smaller structure and reduced weight.
[0005] An object of the present invention is to provide a movable body with variable space that can be miniaturized and lightened.
Means for Solving the Problems
[0006] The spatially variable movable body of the present invention comprises a plurality of panels, one or more telescopic sections provided between the plurality of panels, a movable floor connected to at least one of the plurality of panels and the telescopic sections, a height-direction movable section capable of expanding and contracting the space surrounded by the plurality of panels, the telescopic sections and the movable floor in the height direction, a width-direction movable section capable of expanding and contracting the space in the width direction, a length-direction movable section capable of expanding and contracting the space in the length direction, and a telescopic guide that guides the space to expand or contract in the height direction, the width direction and the length direction, respectively, and when moving, it is possible to be in a contracted state in the height direction, the width direction and the length direction, and when stopped, it is possible to be in an expanded state in the height direction, the width direction and the length direction. [Effects of the Invention]

[Figure 15] (a)(b) Perspective view of a spatially variable movable body in a reduced state according to one embodiment of the present invention. [Modes for carrying out the invention]
[0009] An embodiment of the present invention will be described below with reference to the drawings. Figure 1 is a perspective view of the spatially movable body in a contracted state according to an embodiment of the present invention. Figure 2 is a perspective view of the spatially movable body in an expanded state according to an embodiment of the present invention. In Figures 1 and 2, the spatially movable body 1 of this embodiment comprises a plurality of panels 2 and one or more expandable / contractable sections 3 provided between the plurality of panels 2. The expandable / contractable sections 3 can also serve to connect the plurality of panels 2.
[0010] The materials used for Panel 2 include biodegradable plastics made from nanocellulose extracted from wood and bamboo, metal materials (steel, stainless steel, aluminum), ceramics, porcelain, and glass.
[0011] In addition, as the member of the expansion / contraction part 3, there are materials such as a material (polyester) obtained by applying strong water repellent treatment to a stretch sheet (flameproof) that expands and contracts in all directions, and a material mainly made of gel-like silicon that expands and contracts in all directions. As shown in FIG. 6 described later, the expansion / contraction part 3 may expand and contract in a configuration like an accordion, may expand and contract in a folding manner like a tent, or may expand and contract by using a material like rubber so that the material itself stretches.
[0012] The space-variable movable body 1 can expand and contract in any of its width direction, length direction, and height direction to vary the size and shape of the space. However, by providing the panel 2, the strength and a suitable shape are ensured, and by providing the expansion / contraction part 3, it becomes easy to vary the size and shape of the space. In particular, as the strength, the strength that enables the space-variable movable body 1 to travel when moving in a contracted state and the strength for maintaining the expanded state when parked in the expanded state are required. By adopting such a structure, it is possible to achieve miniaturization and weight reduction while ensuring the required strength. Whether it is a compact vehicle like a light automobile or a large vehicle, that is, for any size of movable body, the size and shape of the space can be varied.
[0013] The towing connection part 12 is for connecting to a towing vehicle or a towing ship when towing the space-variable movable body 1 with a truck or a ship, etc. Towing will be described later.
[0014] Next, referring to FIGS. 3 to 6, the expansion / contraction guide 4 will be described. FIG. 3 is a structural explanatory diagram for explaining the expansion / contraction guide in an embodiment of the present invention. FIG. 4 is a cross-sectional view of the space-variable movable body in a contracted state in an embodiment of the present invention. FIG. 5 is a cross-sectional view of the space-variable movable body in an expanded state in an embodiment of the present invention. FIG. 6 is a cross-sectional view of the space-variable movable body in a contracted state in an embodiment of the present invention.
[0015] The telescopic guide 4 connects to at least the panel to support the panel 2 and the telescopic section 3, and guides the direction of expansion or contraction when expanding or contracting the space enclosed by the panel 2 and the telescopic section 3. In addition, the telescopic guide 4 supports the space so that it maintains its shape whether it is expanded or contracted, and also serves as the framework of the spatially movable body 1. It is preferable to provide telescopic guides 4 that extend in a curved shape in the length and height directions, and telescopic guides 4 that extend in a curved shape in the width and height directions, as shown in Figure 3.
[0016] When the space changes from a contracted state (Figure 4) to an expanded state (Figure 5), the telescopic guide 4 can also be made to expand and change its length. When the telescopic guide 4 extends, the guide extension portion 11, which was hidden inside when it was contracted, is exposed, and the telescopic guide 4 extends by the length of the guide extension portion 11. As a result, the telescopic portion 3 expands by the length of the guide extension portion 11, and the space expands.
[0017] On the other hand, when the space changes from an expanded state (Figure 5) to a contracted state (Figure 4), the telescopic guide 4 can also be changed by reducing its length. When the length of the telescopic guide 4 is shortened, the guide extension portion 11 that was exposed in the expanded state is retracted inward, and the telescopic guide becomes shorter by the length of the guide extension portion 11. As a result, the telescopic portion 3 becomes shorter by the length of the guide extension portion 11, and the space is contracted.
[0018] Next, with reference to Figures 4-7, an example of a height-direction movable unit that can expand and contract the space surrounded by multiple panels 2, expandable sections 3, and a movable floor (described later) in the height direction will be explained.
[0019] Figure 7 is a cross-sectional view of a vertical movement drive unit and a vertical movement guide in one embodiment of the present invention. The height-direction movement unit preferably comprises a vertical movement drive unit 5 and a vertical movement guide 6. The vertical movement drive unit 5 preferably comprises a vertical movement guide support unit 51, a ball screw 52, a connecting unit 53, a motor 54, etc. Also, as shown in Figure 6, the vertical movement guide 6 preferably comprises a panel connecting unit 61.
[0020] The vertical movement guide 6 is a support rod for moving the panel 2 in the height direction. The vertical movement guide support part 51 supports the vertical movement guide 6 so that it does not tilt when it moves. When the ball screw 52 rotates, the connecting part 53 moves in the height direction, and the vertical movement guide 6, which is connected to the connecting part 53, moves. The connecting part 53 connects the ball screw 52 and the vertical movement guide 6. The motor 54 rotates the ball screw 52.
[0021] The panel connecting section 61 connects the panel 2 and the vertical movement guide 6 via the telescopic guide 4. When the motor 54 is driven, the ball screw 52 rotates, and this rotation causes the connecting section 53 to move in the height direction, causing the telescopic guide 4 to expand or contract. The panel connecting section 61 connects the panel 2 and the vertical movement guide 6 via the telescopic guide 4, but the panel 2 or telescopic section 3 may also be directly connected to the vertical movement guide 6. Furthermore, although an example has been described in which the vertical movement drive section 5 and the vertical movement guide 6 are provided as the height-direction movement section, the system is not limited to this, and other forms are also acceptable as long as the structure can expand and contract the space in the height direction.
[0022] Next, referring to Figures 8 to 12, we will describe the fixed floor 7, the movable floor 8, the base 9, and the widthwise and lengthwise movable parts that can reduce and expand the space surrounded by the multiple panels 2, the telescopic section 3, and the movable floor 8 in the widthwise and lengthwise directions. Figure 8 is a diagram illustrating the floor surface when reduced in one embodiment of the present invention. Figure 9 is a diagram illustrating the floor surface when expanded in one embodiment of the present invention. Figure 10 is a diagram illustrating the movable structure of the movable floor in one embodiment of the present invention. Figure 11 is a diagram illustrating the movement of the movable floor in one embodiment of the present invention. Figure 12 is a diagram illustrating the movement of the movable floor in one embodiment of the present invention.
[0023] A widthwise moving section, a lengthwise moving section, a movable floor 8, and a fixed floor 7 are arranged on the base 9 of the spatially movable body 1. The movable floor 8 is connected to the panel 2 as shown in Figure 4. However, the movable floor 8 may also be connected to the telescopic section 3, or the fixed floor 7 may be connected to at least one of the panel 2 and the telescopic section 3.
[0024] As shown in Figures 10 and 11, the widthwise moving section may include a motor 81, a ball screw 82, a linear guide 83, and a connecting section 84. The motor 81 rotates the ball screw 82. As the ball screw 82 rotates, the connecting section 84 moves, and the movable floor 8 connected to the connecting section 84 moves in the widthwise direction. The linear guide 83 is a guide that supports the movable floor 8, which is a surface, so that it does not tilt. The movable floor 8 is attached to a member that moves along the linear guide 83 (rail) fixed to the base 9 to prevent tilting and allow the movable floor to move smoothly. The connecting section 84 connects the ball screw 82 and the movable floor 8. That is, when the motor 81 is driven, the ball screw 82 rotates, and as a result the connecting section 84 moves, so the movable floor 8 moves in the expansion direction or contraction direction on the linear guide.
[0025] As shown in Figures 10 and 12, the longitudinal movement section may include a motor 85, a ball screw 86, a linear guide 87, a connecting section 88, and a drive belt 89. The motor 85 rotates the ball screw 86. As the ball screw 86 rotates, the connecting section 88 moves, causing the connected movable floor 8 to move in the longitudinal direction. The linear guide 87 is a guide that supports the movable floor 8, which is a surface, to prevent it from tilting. The movable floor 8 is attached to a member that moves along the linear guide 87 (rail) fixed to the base 9 to prevent tilting and allow for smooth movement. The connecting section 88 connects the ball screw 86 and the movable floor 8. The drive belt 89 is used when the motor 85 and the ball screw 86 cannot be connected in a straight line, by arranging them in parallel as shown in Figure 10 and connecting the shafts of the motor 85 and the ball screw 86 with a belt. In other words, the movable floor 8 is supported on a base 9 by linear guides 83 and 87, and is moved using a drive belt 89 by motors 81 and 85 which drive ball screws 82 and 86.
[0026] As the movable floor 8 shrinks or expands in the width and length directions due to the above configuration, the length of the telescopic guide 4 changes even without any change in the length of the vertical movement drive unit 5.
[0027] Of course, the height-direction movement section, width-direction movement section, and length-direction movement section described so far are just examples, and other structures may be used.
[0028] Next, the uses of the spatially variable mobile body 1 will be explained using Figures 13 to 15. Figure 13 is a diagram showing an example of the use of the spatially variable mobile body when expanded in one embodiment of the present invention. Figure 14 is a side view of the spatially variable mobile body when moving in one embodiment of the present invention. Figures 15(a) and 15(b) are perspective views of the spatially variable mobile body when contracted in one embodiment of the present invention.
[0029] The spatially variable mobile body 1 can be in a contracted state while in motion. This allows it to fit within the dimensions stipulated by the Road Transport Vehicle Act while in motion. The Road Transport Vehicle Act stipulates, for example, that a light vehicle must fit within 3.40m in length, 1.48m in width, and 2.00m in height; a compact vehicle must fit within 4.70m in length, 1.70m in width, and 2.00m in height; and a regular vehicle must fit within 12.0m in length, 2.50m in width, and 3.80m in height.
[0030] On the other hand, the spatially variable mobile body 1 can expand its space when stopped. The volume of the space in the expanded state can be 1.5 to 3 times the volume of the space in the contracted state. As a result, when stopped, the spatially variable mobile body 1 can obtain a space that exceeds the size stipulated by the Road Traffic Act.
[0031] Such a spatially adaptable mobile vehicle 1 can function as a shop, kitchen, accommodation, hotel, residence, campsite, leisure space, remote work space, disaster relief facility, hospital ward, government office, etc., when stationary. As a result, the spatially adaptable mobile vehicle 1 can be used as a mobile sales or mobile facility. In the example in Figure 13, the stationary spatially adaptable mobile vehicle 1 is being used as a shop. When stationary, the spatially adaptable mobile vehicle 1 can obtain space that exceeds the size stipulated by the Road Traffic Act, so it can secure sufficient space to be used as a shop.
[0032] The spatially movable mobile body 1 may or may not have the ability to move on its own. As shown in Figure 14, it may be towed by a truck or the like and move along the road. Alternatively, it may be towed by a ship or the like and move across the sea. It can be connected to a towing vehicle or towing ship using the towing coupling part 12. In any case, when being towed, the spatially movable mobile body 1 is preferably in a contracted state. Furthermore, as shown in Figure 15, by applying the configuration of the spatially movable mobile body 1 described above to at least a part of the passenger space of a regular car or a small car, the spatially movable mobile body 1 itself can be made capable of moving on its own. (a) shows the contracted state, and (b) shows the expanded state. In this case, it is useful in the above-mentioned examples of use, and is particularly useful as a camper van or mobile sales vehicle.
[0033] Regarding its applications, the examples described primarily focus on the expansion and contraction of the spatially variable mobile body 1 during land travel. However, it can also be used as a spatially variable mobile body 1 for travel on water surfaces such as seas and lakes. Furthermore, it can be similarly applied as an expandable and contractible spatially variable mobile body 1 for travel in the air or into outer space.
[0034] The spatially variable movable body 1 of the present invention comprises a plurality of panels 2, one or more telescopic parts 3 provided between the plurality of panels 2, a movable floor 8 connected to at least one of the plurality of panels 2 and telescopic parts 3, a height-direction movable part that can expand and contract the space surrounded by the plurality of panels 2, telescopic parts 3 and movable floor 8 in the height direction, a width-direction movable part that can expand and contract the space in the width direction, a length-direction movable part that can expand and contract the space in the length direction, and a telescopic guide 4 that guides the space to expand or contract in the height direction, width direction and length direction, respectively. When moving, it is possible to be in a contracted state in the height direction, width direction and length direction, and when stopped, it is possible to be in an expanded state in the height direction, width direction and length direction. This makes it possible to provide a spatially variable movable body that can be miniaturized and lightened. [Industrial applicability]
