Description

The present invention relates to a spatially variable moving object.

BACKGROUND ART Conventionally, specially equipped vehicles (for example, Patent Document 1) are known in which the side surfaces of the body are widened. Such specially equipped vehicles can be expanded laterally when necessary, so when a disaster such as an earthquake occurs, they are used as facilities for dispatching to affected areas and accommodating disaster victims.

JP2021-187425A

By the way, if it is a specially equipped vehicle that is dispatched to a disaster site, there is no problem with a heavy configuration as in Patent Document 1, but it is not a vehicle that ordinary people can easily drive. However, even ordinary people can secure a large interior space at their destination if they can own a moving body whose space can be expanded or contracted. To this end, it is desirable to have a mobile body with a smaller structure and lighter weight.

An object of the present invention is to provide a spatially variable moving body that can be made smaller and lighter.

The spatially variable moving body of the present invention includes a plurality of panels, one or more extendable parts provided between the plurality of panels, and a moving floor connected to at least one of the plurality of panels and the extendable part. a height direction moving part capable of expanding or contracting the space surrounded by the plurality of panels, the expansion/contraction part, and the moving floor in the height direction; and a height direction moving part capable of expanding or contracting the space in the width direction. a widthwise moving section that can expand or contract the space in the lengthwise direction, and a lengthwise moving section that can expand or contract the space in the height direction, the width direction, and the lengthwise direction. The telescopic guide is provided with a telescopic guide that guides the user so that the height direction, the width direction, and the length direction are reduced during the movement. It is possible to be expanded in the longitudinal direction.

According to the present invention, it is possible to provide a spatially variable moving body that can be made smaller and lighter.

An embodiment embodying the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a spatially variable moving body when contracted according to an embodiment of the present invention. FIG. 2 is a perspective view of the spatially variable moving body when expanded according to an embodiment of the present invention. In FIGS. 1 and 2, a spatially variable moving body 1 according to the present embodiment includes a plurality of panels 2 and one or more extensible parts 3 provided between the plurality of panels 2. The stretchable part 3 can also play a role of connecting a plurality of panels 2.

Materials for the panel 2 include wood, biodegradable plastic made from nanocellulose extracted from bamboo, metal materials (steel, stainless steel, and aluminum), ceramics, porcelain, and glass materials.

In addition, the materials for the elastic part 3 include a stretch sheet (flame retardant) that stretches in all directions, a material (polyester) with a strong water repellent finish, and a gel-like silicone-based material that stretches in all directions. There is. As shown in FIG. 6, which will be described later, the extensible part 3 may be configured to expand and contract like an accordion, or it can be expanded and contracted in a folding manner like a tent, or it can be expanded and contracted by using a material such as rubber. It may be expanded or contracted so that it stretches itself.

The space-variable moving body 1 can be expanded or contracted in any of its width, length, and height directions to change the size and shape of the space. By ensuring a certain shape and providing the expandable part 3, it becomes easy to change the size and shape of the space. In particular, as strength, strength is required to enable the space-variable moving body 1 to travel when moving in the contracted state, and strength to maintain the expanded state when stopped in the expanded state. With this structure, it is possible to reduce the size and weight while ensuring the necessary strength, and it can be used for any size vehicle, whether it is a compact vehicle such as a light vehicle or a large vehicle. Even in a moving body, the size and shape of the space can be changed.

The towing connection part 12 is for connecting to a tow vehicle or a tow boat when the spatially variable moving body 1 is towed by a truck, a ship, or the like. Towing will be discussed later.

Next, the telescopic guide 4 will be explained with reference to FIGS. 3 to 6. FIG. 3 is a structural explanatory diagram for explaining the telescoping guide in one embodiment of the present invention. FIG. 4 is a cross-sectional view of the spatially variable moving body when contracted according to an embodiment of the present invention.
FIG. 5 is a cross-sectional view of the spatially variable moving body when expanded according to an embodiment of the present invention. FIG. 6 is a cross-sectional view of the spatially variable moving body when contracted according to an embodiment of the present invention.

The telescoping guide 4 is connected to at least the panel, supports the panel 2 and the telescoping section 3, and guides the direction of expansion or contraction when expanding or contracting the space surrounded by the panel 2, the telescoping section 3, and the like. Furthermore, whether the space is in an expanded state or a contracted state, the telescopic guide 4 supports the space so that its shape can be maintained, and also serves as the framework of the space-variable moving body 1. As shown in FIG. 3, it is preferable to provide an extensible guide 4 that extends in a curved manner in the length direction and the height direction, and an extensible guide 4 that extends in a curved manner in the width direction and the height direction.

When changing from a state in which the space is contracted (FIG. 4) to a state in which the space is expanded (FIG. 5), the telescoping guide 4 can also be varied by expanding its length. When the telescopic guide 4 is extended, the guide extension part 11 that was hidden inside in the contracted state is exposed, and the telescoping guide 4 is extended by the length of the guide extension part 11. As a result, the extendable portion 3 expands by the length of the guide extender 11, expanding the space.

On the other hand, when changing from a state where the space is expanding (FIG. 5) to a state where the space is contracting (FIG. 4), the telescoping guide 4 can also be changed by reducing its length. When the length of the telescopic guide 4 is shortened, the guide extension part 11 exposed in the expanded state is stored inside, and the telescoping guide is shortened by the length of the guide extension part 11. As a result, the extendable portion 3 becomes shorter by the length of the guide extender 11, and the space is reduced.

Next, with reference to FIGS. 4 to 7, an example of a height-direction movable part that can expand or contract in the height direction a space surrounded by a plurality of panels 2, an extensible part 3, a movable floor described below, etc. I will explain about it.

FIG. 7 is a sectional view of a vertical movement drive unit and a vertical movement guide in an embodiment of the present invention. The height direction moving section may include a vertical movement drive section 5 and a vertical movement guide 6. The vertical motion drive section 5 may include a vertical motion guide support section 51, a ball screw 52, a connecting section 53, a motor 54, and the like. Moreover, as shown in FIG. 6, the vertical movement guide 6 is preferably provided with a panel connecting portion 61.

The vertical movement guide 6 is a support rod when 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. As the ball screw 52 rotates, the connecting portion 53 moves in the height direction, and the vertical movement guide 6 connected to the connecting portion 53 moves. The connecting portion 53 connects the ball screw 52 and the vertical movement guide 6. The motor 54 rotates the ball screw 52.

The panel connecting portion 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 moves the connecting portion 53 in the height direction, causing the telescopic guide 4 to expand or contract. Although the panel connecting portion 61 connects the panel 2 and the vertical movement guide 6 via the telescoping guide 4, the panel 2 or the expansion/contraction portion 3 may be directly connected to the vertical movement guide 6. Further, an example has been described in which the vertical movement drive unit 5 and the vertical movement guide 6 are provided as the height direction moving unit, but the structure is not limited to this, and other forms may be used as long as the structure can expand or contract the space in the height direction. Also good.

Next, with reference to FIGS. 8 to 12, the fixed floor 7, movable floor 8, and base 9, and the space surrounded by the plurality of panels 2, the expandable part 3, and the movable floor 8, will be examined in the width and length directions. A widthwise moving section and a lengthwise moving section that can be contracted and expanded will be explained. FIG. 8 is a diagram illustrating a floor surface during reduction in an embodiment of the present invention. FIG. 9 is a diagram illustrating the floor surface during expansion in one embodiment of the present invention. FIG. 10 is a diagram illustrating a moving structure of a moving bed in an embodiment of the present invention. FIG. 11 is a diagram illustrating movement of a moving bed in an embodiment of the present invention. FIG. 12 is a diagram illustrating movement of a moving bed in an embodiment of the present invention.

A widthwise moving section, a lengthwise moving section, a moving bed 8, and a fixed bed 7 are arranged on a base 9 of the spatially movable moving body 1. The moving floor 8 is connected to the panel 2 as shown in FIG. However, the movable floor 8 may be connected to the telescopic section 3, or the fixed bed 7 may be connected to at least one of the panel 2 and the telescopic section 3.

As shown in FIGS. 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. Motor 81 rotates ball screw 82 . As the ball screw 82 rotates, the connecting portion 84 moves, and the movable bed 8 connected to the connecting portion 84 moves in the width direction. The linear guide 83 is a guide that supports the movable floor 8, which is a surface, so that it does not tilt. A movable floor 8 is attached to a member that moves along a linear guide 83 (rail) fixed to a base 9 to prevent inclination and allow the movable floor to move smoothly. The connecting portion 84 connects the ball screw 82 and the moving floor 8. That is, the motor 81 is driven to rotate the ball screw 82, thereby moving the connecting portion 84, so that the movable bed 8 moves in the expansion direction or in the contraction direction on the linear guide.

As shown in FIGS. 10 and 12, the longitudinal moving section may include a motor 85, a ball screw 86, a linear guide 87, a connecting section 88, and a drive belt 89. Motor 85 rotates ball screw 86 . As the ball screw 86 rotates, the connecting portion 88 moves, and the connected movable bed 8 moves in the length direction. The linear guide 87 is a guide that supports the movable floor 8, which is a surface, so that it does not tilt. A moving floor 8 is attached to a member that moves along a linear guide 87 (rail) fixed to a base 9 to prevent inclination and enable smooth movement. The connecting portion 88 connects the ball screw 86 and the moving floor 8. When the motor 85 and the ball screw 86 cannot be connected in a straight line, the drive belt 89 connects the shaft of the motor 85 and the shaft of the ball screw 86 by arranging them in parallel as shown in FIG. 10. That is, the movable floor 8 is supported by linear guides 83 and 87 on the base 9, and is moved by driving the motors 81 and 85 to rotate the ball screws 82 and 86 and using the drive belt 89.

As the movable bed 8 contracts or expands in the width direction and the length direction due to the above-described configuration, the length of the telescopic guide 4 changes even if the length of the vertical movement drive section 5 does not change.

Of course, the height direction moving part, the width direction moving part, and the length direction moving part which have been explained so far are just examples, and structures other than those described above may be used.

Next, using FIGS. 13 to 15, the usage of the spatially variable moving body 1 will be explained. FIG. 13 is a diagram illustrating an example of the use of a spatially variable moving body during expansion according to an embodiment of the present invention. FIG. 14 is a side view of a spatially variable moving body during movement according to an embodiment of the present invention. FIGS. 15(a) and 15(b) are perspective views of a spatially variable moving body when contracted according to an embodiment of the present invention.

The spatially variable moving body 1 can be in a reduced state when traveling. This allows the vehicle to be kept within the dimensions stipulated by the Road Transport Vehicle Law when traveling. According to the Road Transport Vehicle Act, for example, a light vehicle must be within 3.40 m in length, 1.48 m in width, and 2.00 m in height, and a small vehicle must be within 4.70 m in length and 1 in width. It is stipulated that the length of the vehicle must be within .70m and the height of 2.00m, and for a regular car, the length must be within 12.0m, the width of 2.50m, and the height of 3.80m.

On the other hand, the spatially variable moving body 1 can expand its space when stopped. The volume of the space in the expanded state may be 1.5 to 3 times the volume of the space in the contracted state. As a result, when the vehicle is stopped, the spatially variable mobile body 1 can obtain a space exceeding the size specified by the Road Traffic Act.

Such a spatially variable moving body 1 can be used as a store, kitchen, accommodation facility, hotel, residence, camping, leisure, remote work space, disaster facility, hospital ward, government office, etc. when stopped. As a result, the spatially variable mobile body 1 can be used for mobile sales or as a mobile facility. In the example of FIG. 13, the stopped spatially variable mobile object 1 is used as a store. Since the space-variable mobile body 1 can obtain a space exceeding the size specified by the Road Traffic Act when stopped, it can secure sufficient space for a store.

The spatially variable moving body 1 may or may not have a running ability, and may be towed by a truck or the like and moved on a road as shown in FIG. Alternatively, it may be moved on the sea by being towed by a ship or the like. It can be connected to a towing vehicle or a towing boat using the towing connection part 12. In any case, when being towed and moving, it is preferable that the spatially variable moving body 1 is in a contracted state. In addition, as shown in FIG. 15, by applying the configuration of the space-variable moving body 1 described above to at least a part of the passenger space of a regular car or a small car, the space-variable moving body 1 itself has a driving capability. can be ensured. (a) shows the time of reduction, and (b) shows the time of expansion. In this case, it is useful in the above-mentioned usage examples, and is particularly useful as a camping car, a mobile sales vehicle, etc.

Regarding the usage, we have mainly explained an example in which the spatially variable moving body 1 expands, contracts, and expands when moving on land, but it can also be used as a spatially variable moving body 1 when moving on water such as the sea or lake. good. Furthermore, it can be similarly applied as a spatially variable mobile body 1 that can be extended, contracted, and expanded for movement in the sky or space.

The spatially variable moving body 1 of the present invention includes a plurality of panels 2, one or more telescoping sections 3 provided between the plurality of panels 2, and connected to at least one of the plurality of panels 2 and the telescoping section 3. A moving floor 8, a height moving section capable of expanding and contracting the space surrounded by the plurality of panels 2, the expandable section 3, and the moving floor 8 in the height direction, and a height direction moving section that can expand and contract the space in the width direction. a widthwise moving part that can expand or contract the space in the lengthwise direction; a lengthwise moving part that can expand or contract the space in the lengthwise direction; It is equipped with a telescopic guide 4 for guiding, and can be in a contracted state in the height direction, width direction, and length direction when moving, and can be in an expanded state in the height direction, width direction, and length direction when stopped. Is possible. This makes it possible to provide a spatially variable moving body that can be made smaller and lighter.
