Description

  The present invention relates to a composite frame material of different materials and a moving body.

  In moving bodies with cabins surrounded by walls and ceilings, such as campers, trailer houses, mobile sales vehicles, and sightseeing ships, cabins are manufactured or modified by custom or small lot according to purpose, so-called one-off (Hereinafter referred to as “one-off production”). The cabin of such a moving body is manufactured one-off in consideration of ensuring that sufficient strength is ensured since an external force is always applied during movement and that the moving body does not roll over when tilted at a predetermined angle. . In addition, with the diversification of designs, there is a desire to make a one-off production of a moving cabin with a curved exterior surface.

  In response to the desire to make a one-off manufacturing of a moving body cabin having a curved outer wall surface, it is conceivable to manufacture the moving body cabin with a monocoque structure or a frame structure. The monocoque structure requires expensive molds and equipment. For this reason, it is not realistic to adopt a monocoque structure in a mobile cabin manufactured one-off. On the other hand, the frame structure is composed of a cabin frame made of a frame material and an outer wall supported by the cabin frame, and basically is a structure that ensures firm strength with the cabin frame. The strength of the frame structure can be increased relatively easily by using a solid frame material, and it is not necessary to use expensive molds and equipment as the monocoque structure. For this reason, it is more realistic to adopt a frame structure in a mobile cabin manufactured one-off.

  Patent Document 1 discloses a vehicle structure of a camper in which an exterior surface is a curved surface and a curved frame material (reinforcing member) is fixed to an exterior material (cabin housing) with an adhesive (Patent Document 1). Paragraph [0010] and FIG. 1 etc.). The frame material (reinforcing member) disclosed in Patent Document 1 is formed by curving a U-shaped steel material corresponding to the inner surface of the exterior material (cabin housing) (see Patent Document 1). (See paragraph [0010].)

JP-A-9-169238

  However, the use of a three-dimensional metal material as a frame material, such as a steel material having a U-shaped cross section or a metal hollow pipe as disclosed in Patent Document 1, is a three-dimensional metal material having a high bending strength. Is difficult to bend to a desired curvature, which increases the difficulty of one-off fabrication. However, it is difficult to ensure the strength even if the frame material is formed only with a thin metal plate. Note that the use of a thick metal material as a frame material increases the weight and tends to roll over when the moving body is tilted. For this reason, the conventional frame material has room for improvement in response to the desire to make a one-off production of a moving body cabin having a curved exterior surface.

In view of such demands, the present invention provides a frame material that can fix the exterior material so that the exterior surface becomes a curved surface, is lightweight and has sufficient strength, and is easy to use for one-off production of a cabin of a moving body. The challenge is to do.
Another object of the present invention is to provide a movable body that can be manufactured one-off, and includes a cabin having a curved exterior surface and a light weight and sufficient strength.

[1] A dissimilar material composite frame material according to the present invention is a frame material that supports an exterior material of a cabin of a moving body having a cabin, and is a support curved surface that serves as a support surface of the exterior material and is perpendicular to the support curved surface. A thick plate made of wood or resin having a first flat surface, a first frame portion extending curvedly according to the support curved surface, a second flat surface in the plate thickness direction, and curved along the first frame portion. And a second frame part that is in contact with the first frame part and is in close contact with the first plane. In the present specification, the “plate thickness direction” refers to the direction in which the distance between the opposing surfaces of the plate material is the shortest, and “thickness” refers to the width dimension in the plate thickness direction. In this specification, a plate having a thickness of 10 mm or more is referred to as a “thick plate”, and a plate having a thickness less than 10 mm is referred to as a “flat plate”.

  According to the dissimilar composite frame material according to the present invention, since the first frame portion which is a wooden or resin thick plate having a support curved surface serving as a support surface of the exterior material is provided, the exterior material is supported along the support curved surface. By fixing so that it can be used, it can be used to form the exterior surface of the cabin into a curved surface. In this specification, “the exterior surface is a curved surface” is not only “the exterior surface is a curved surface that is not strictly uneven”, but “the exterior surface is slightly uneven even when slightly observed. It also means “a surface that looks like a curved surface”.

  Further, in the dissimilar material composite frame material according to the present invention, the first frame portion which is a wooden or resin thick plate having a first plane perpendicular to the support curved surface, and is curved along the first frame portion. And a second frame part that is a metal flat plate extending in a straight line, and the second plane is in close contact with and joined to the first plane. For this reason, according to the dissimilar composite frame material according to the present invention, the first frame portion is made of wood and thus is reduced in weight, and the second frame portion is made of metal to partially increase the strength. Therefore, it can be used to form a main skeleton of a cabin having a light weight and sufficient strength without making the first frame portion extremely thick.

  Also, according to the composite frame material of different materials according to the present invention, the first frame part is a thick plate made of wood or resin, and the second frame part is a metal flat plate. It is possible to form a beautiful curved surface cheaply and easily than bending a three-dimensional metal material such as a U-shaped steel material or a hollow square steel material. That is, the dissimilar material composite frame material according to the present invention can be said to be a frame material that is easy to use for one-off production of a cabin of a moving body.

Become a material.

[2] In the dissimilar composite frame material according to the present invention, it is preferable that the first frame portion has a constant curvature radius of the support curved surface and is curved and extends according to the support curved surface.

  The dissimilar material composite frame material configured in this manner is a frame material having high strength because the curvature radius of the support curved surface of the first frame portion is constant and stress concentration due to external force is unlikely to occur.

[3] In the dissimilar composite frame material according to the present invention, the first frame portion is easy to use when the radius of curvature of the support curved surface is 1800 mm to 2500 mm. In the dissimilar composite frame material according to the present invention, the first frame portion is easy to use when the curvature radius of the support curved surface is 2300 mm.

  The different material composite frame material configured as described above is configured by combining the frame materials symmetrically so that the width of the internal space is about 1900 mm and the height of the internal space is about 1800 mm, for example. In addition, since a cabin can be formed that can accommodate a sufficient amount of people and adapt to the width of the vehicle, the frame material can be easily applied to a cabin for a moving vehicle such as a camper or a moving vehicle.

[4] A moving body according to the present invention is a moving body having a cabin, and a cabin frame in which the main skeleton of the cabin is formed of a plurality of frame members, and the cabin exterior surface is supported by the cabin frame. And a dissimilar material composite frame material according to the present invention is used as a frame material.

  According to the movable body according to the present invention, it has a cabin including a cabin frame formed of a frame material and an exterior material formed so that the exterior surface has a curved shape, and the different material composite according to the present invention is used as the frame material. Since the frame material is used, the effect of the different material composite frame material according to the present invention can be enjoyed.

  As a result, the mobile body according to the present invention is a mobile body that can be manufactured one-off including a cabin having a curved exterior surface and light weight and sufficient strength.

[5] In the moving body according to the present invention, the frame member has a mating surface that forms an acute angle with the support curved surface at one end, and the cabin frame is disposed symmetrically and joined together by matching the mating surfaces. It is preferable that the main skeleton is formed by arranging a plurality of pairs of frame materials.

  Since the movable body configured in this way forms a same curved surface by a plurality of support curved surfaces on each of the left and right sides by arranging a plurality of pairs of symmetrical left and right frame materials, it can firmly support the exterior material as a clean curved surface. It becomes a moving body.

[6] In the mobile body according to the present invention, the left and right exterior surfaces of the cabin may connect the upper ends of each other.

  The mobile body configured in this manner is a mobile body having a cabin with excellent twisting strength because a substantially triangular frame is formed by the frame material supporting the left and right exterior surfaces and the cabin floor. In addition, even if the moving body comprised in this way is a substantially triangular shape, since the frame material is curving and extending according to a support curved surface, it becomes a moving body with which sufficient cabin space was ensured.

[7] In the moving body according to the present invention, it is preferable that the cabin frame further includes a frame connecting member that is disposed between the frame members and has both end portions joined to adjacent frame members.

  The moving body configured in this way is such that the frame members are more firmly connected by the frame connecting member, so that the frame member is less likely to fall down and becomes a moving body having a stronger cabin.

[8] In the movable body according to the present invention, the exterior material may be fixed to the support curved surface of the first frame portion of the different material composite frame material as the frame material by a fastener that penetrates the exterior material. .

  The moving body configured in this manner is a moving body having a cabin that is easy to manufacture one-off because the exterior material can be easily and firmly fixed to the frame material by the fastener.

[9] In the mobile body according to the present invention, a plurality of long wooden siding materials as exterior materials are arranged in the vertical direction so that the ridge lines extending in the longitudinal direction of the siding materials overlap each other. They may be formed in combination.

  Since the moving body configured in this way does not have to be manufactured using a large and heavy exterior material, the moving body has a cabin that is easy to manufacture one-off. In addition, wooden siding materials are arranged side by side in the vertical direction, making it hard to give a feeling of fit and forming a wall with an excellent wooden design that blends naturally, so that it calms naturally into the viewer. It becomes a moving body with an excellent design capable of giving a good impression.

  In the different-material composite frame material 11, the curvature radius RA of the support curved surface of the first frame portion 11a is 2300 mm to 2500 mm, and more specifically, the curvature radius RA of the support curved surface of the first frame portion 11a is 2300 mm. The composite frame material 11 made of different materials as described above constitutes the cabin frame 10 by combining the frame materials 11 symmetrically so that the width of the internal space is about 1900 mm and the height of the internal space is about 1800 mm. By doing so, the cabin 3 that can be fully inserted into the interior and adaptable to the width of the vehicle can be formed, so that the frame material can be easily applied to a cabin for a mobile vehicle such as a camper or a mobile sales vehicle. Even if the curvature radius of the support curved surface in the composite frame material of different materials is 1800 mm to 2100 mm, the cabin frame 10 that can secure the height of the internal space about 1800 mm can be configured, and the cabin for a mobile vehicle can be configured. The frame material is easy to apply.

  According to the moving body 1, it has the cabin 3 provided with the cabin frame 10 formed with a frame material, and the exterior material 20 formed so that an exterior surface may become a curved surface shape, and the different material composite frame material 11 is used as a frame material. Since it is used, the effect of the different material composite frame material 11 can be enjoyed.

  As a result, the movable body 1 is a movable body that can be manufactured one-off with the cabin 3 having a curved exterior surface and light weight and sufficient strength.

  In the moving body 1, the dissimilar material composite frame material 11 has a mating surface that forms an acute angle θ2 with the support curved surface at one end portion, and is arranged symmetrically and joined together by matching the mating surfaces. Since the main skeleton is formed by the cabin frame 10 in which a plurality of sets are arranged, the moving body 1 has a plurality of support curved surfaces on each of the left and right sides by arranging a plurality of pairs of bilaterally symmetric different material composite frame members 11. Since the same curved surface is formed, the movable body 20 can be firmly supported as a clean curved surface.

  In the moving body 1, the left and right exterior surfaces of the cabin 3 are connected to each other's upper end portions, so that the movable body 1 includes the different material composite frame material 11 that supports the left and right exterior surfaces and the cabin 3. Since a substantially triangular frame is formed on the floor, the moving body has the cabin 3 having excellent twisting strength. In addition, even if the moving body 1 configured in this way has a substantially triangular shape, the different-material composite frame material 11 is curved and extends according to the support curved surface, so that the cabin space is sufficiently secured. Become.

  In the moving body 1, the frame connecting member 12 is arranged between the different material composite frame members 11 along the exterior material 20 in the cabin frame 10, and both ends are joined to the adjacent different material composite frame members 11. Therefore, since the different-material composite frame material 11 is more firmly connected by the frame connecting member 12, the moving body 1 has the cabin 3 having higher strength because the different-material composite frame material 11 is less likely to fall down. It becomes a moving body.

  In the moving body 1, the exterior body 20 is fixed to the support curved surface of the first frame portion 11 a in the different material composite frame material 11 by a fastener that penetrates the exterior material 20. Since the exterior material 20 can be easily and firmly fixed to the dissimilar material composite frame material 11 by the tool, it becomes a moving body having the cabin 3 that can be easily manufactured one-off.

  In the mobile body 1, a plurality of long wooden siding materials 21 as the exterior material 20 are combined side by side in the vertical direction UD so that the ridge lines extending in the longitudinal direction of the siding material 21 overlap each other. Thus, the moving body 1 does not have to be manufactured using a large and heavy exterior material, and thus the moving body 1 has a cabin 3 that is easy to manufacture one-off. Moreover, the wooden siding material 21 is combined side by side in the vertical direction UD, so that it is hard to give a feeling of fit and the wall surface of an excellent wooden design that blends naturally is formed, so it blends naturally into the viewer. It becomes a moving body with an excellent design that can give a calm impression.

The different material composite frame is formed such that the width dimension of the second frame part is smaller than the width dimension of the first frame part, and a groove is formed in the first frame part, and the second frame part is the first frame part. (The surface of the groove of the first frame portion becomes the first plane and is in close contact with the second plane of the second frame portion).

(5) In the embodiment described above, the different material composite frame 11 (first frame portion 11a) has been described as having a constant curvature radius RA of the support curved surface, but is not limited thereto. For example, the composite frame of different materials is 1600 mm, 1800 mm, 2000 mm, 1800 mm as the curvature radius RA of the support curved surface goes from the upper side U to the lower side D so that it can be used to construct an egg-shaped cabin frame. It may be changed. Further, the different material composite frame may partially have a radius of curvature RA of 0 mm (partially straight).
