1. 1. Overall Configuration of the Trailer House FIG. 1 is a schematic perspective view showing the overall configuration of the trailer house 1 according to the embodiment of the present invention. The trailer house 1 includes a log house 2 and a trailer 3 that are detachable from each other.

The log house 2 is an assembly-type house formed by combining a plurality of wall materials (log materials 21) made of wood, for example. Inside the assembled log house 2, a living space is formed so that one to several people can live in it. However, the log material 21 may contain a wall material other than wood, and at least a part of the log house 2 may be formed of other than wood.

The trailer 3 includes a chassis body 31, wheels 32, a connecting portion 33, and the like. The chassis body 31 is formed in a rectangular shape in a plan view, for example, and the log house 2 is placed on the upper surface thereof. In order to register the trailer 3 as a chassis with vehicle inspection, it is a condition that the dimensions of the chassis body 31 in the length direction D1 and the width direction D2 are within a predetermined dimension range. In this case, the dimensions of the log house 2 installed on the chassis body 31 are also limited.

The wheels 32 are rotatably attached to the chassis body 31. The number of wheels 32 is, for example, four, but the number is not limited to this, and may be two or three. The chassis body 31 can be attached to and detached from a vehicle (not shown) such as an automobile via the connecting portion 33. If the vehicle is moved with the connecting portion 33 connected to the vehicle, the wheels 32 can be rolled and the chassis body 31 can be moved together with the vehicle. Therefore, the log house 2 can be freely moved by towing the trailer 3 with a vehicle while the log house 2 is mounted on the chassis body 31.

L-shaped cover members 4 are erected at the four corners of the chassis body 31. Each cover member 4 is, for example, a long plate-shaped member made of metal, and has an L-shaped cross section. Each cover member 4 is fixed to the chassis body 31 so that its L-shape extends along the corners of the chassis body 31 in the vertical direction.

The log house 2 is inserted from above into a rectangular space formed by four cover members 4 erected on the chassis body 31. The log house 2 has a rectangular flat shape corresponding to the chassis main body 31. The dimension of the log house 2 in the length direction D1 is substantially the same as the distance between the corners of the cover members 4 arranged in the length direction D1. Further, the dimension of the log house 2 in the width direction D2 is substantially the same as the distance between the corners of the cover members 4 arranged in the width direction D2. When the log house 2 is installed from above with respect to the chassis main body 31, each corner of the log house 2 abuts along the L-shape of each cover member 4 and is fixed to each cover member 4.

As shown in FIG. 1, the outer wall surface of the log house 2 is substantially flush with the outer peripheral surface of the chassis main body 31. That is, when the log house 2 installed on the chassis main body 31 is viewed from above, the four outer wall surfaces of the log house 2 are substantially along the rectangular outer peripheral surface of the chassis main body 31, respectively. However, "substantially flush" includes not only a state in which the outer wall surface of the log house 2 is completely along the outer peripheral surface of the chassis body 31, but also a state in which the log house 2 is slightly deviated from that state (for example, within a few cm). .. Although not shown in FIG. 1, the outer wall surface of the log house 2 is provided with an opening and a door for people to enter and exit the log house 2.

2. Assembling Mode of Log House FIG. 2 is a schematic perspective view for explaining an assembling mode of log house 2. The log house 2 is assembled by the dovetail notch method. In the dovetail notch method, the tip portions of the log members 21 are fitted to each other so that the tip surface 211 of one log member 21 does not protrude from the surface 212 of the other log member 21.

Specifically, stepped surfaces 213 cut off in a concave shape are formed at both ends of the tip surface 211 of each log material 21. By sequentially superimposing the log materials 21 so that the step surfaces 213 formed on the tip surface 211 of the adjacent log materials 21 are in contact with each other, the plurality of log materials 21 mesh with each other on the step surface 213. It is firmly connected. If the stepped surface 213 is formed in a wedge shape, the log materials 21 can be connected more firmly.

However, the log house 2 is not limited to the configuration in which all the log materials 21 are assembled by the dovetail notch method. For example, at the four corners of the log house 2, the portions facing the L-shaped cover member 4 may be assembled at least by the dovetail notch method.

3. 3. Configuration around the cover member FIG. 3 is a schematic perspective view for explaining the configuration around the cover member 4, and shows a state before the log house 2 is placed on the chassis main body 31. FIG. 4 is a schematic cross-sectional view for explaining the configuration around the cover member 4.

As shown in FIG. 3, insertion holes 311 for inserting the cover member 4 are formed at each of the four corners of the chassis body 31. The insertion hole 311 is formed in an L shape corresponding to the cross-sectional shape of the cover member 4, and is composed of recesses extending downward from the upper surface of the chassis body 31.

Each cover member 4 is positioned with respect to the chassis body 31 by being inserted into the corresponding insertion holes 311 from above. Each cover member 4 may be fixed to the chassis body 31 by using a fixture (not shown) such as a bolt and a nut. The deeper the depth of the recess forming the insertion hole 311 is, the longer the insertion portion of the cover member 4 becomes, and the more stable the mounting state of the cover member 4 with respect to the chassis body 31 is.

Each cover member 4 includes a first plate portion 41 parallel to the length direction D1 and a second plate portion 42 parallel to the width direction D2. The first plate portion 41 and the second plate portion 42 are formed in an L shape by connecting their respective ends to each other. However, the first plate portion 41 and the second plate portion 42 may be formed by bending one plate-shaped member.

Each cover member 4 is formed with a plurality of through holes 44 for inserting the fixture 43. The through holes 44 are formed at predetermined intervals in the longitudinal direction of the cover member 4. In this example, in each of the first plate portion 41 and the second plate portion 42, a plurality of through holes 44 are formed at predetermined intervals in the longitudinal direction. The spacing between the through holes 44 in the longitudinal direction may be substantially equal.

Further, the positions of the through holes 44 formed in the first plate portion 41 and the positions of the through holes 44 formed in the second plate portion 42 may be deviated from each other in the longitudinal direction. That is, the position of each through hole 44 formed in the first plate portion 41 in the longitudinal direction may be located between the through holes 44 formed in the second plate portion 42. In this case, it is necessary to prevent the fixture 43 inserted through each through hole 44 of the first plate portion 41 and the fixture 43 inserted through each through hole 44 of the second plate portion 42 from interfering with each other. Can be done.

As shown in FIG. 4, each fixture 43 is fixed in a state of penetrating each through hole 44 of the cover member 4 and further penetrating the log material 21. As a result, the cover member 4 and the log material 21 facing each other are tightened by the fixtures 43. More specifically, the fixture 43 inserted into each through hole 44 of the first plate portion 41 is fixed to the log material 21 extending along the length direction D1 and is fixed to each through hole 44 of the second plate portion 42. The fixture 43 inserted into the log member 43 is fixed to the log material 21 extending along the width direction D2.

Each cover member 4 is provided with a hook member 45 for lifting. For example, a crane hook can be hooked on the hook member 45 to lift it. In this example, the ring-shaped hook member 45 is rotatably attached to the cover member 4. However, the present invention is not limited to such a configuration, and the hook member 45 does not have to be ring-shaped or may not be rotatable.

In this example, hook members 45 are provided at both ends in the longitudinal direction of the first plate portion 41 of the cover member 4. However, the configuration is not limited to this, and the hook member 45 may be provided on the second plate portion 42 of the cover member 4. Further, the hook member 45 may be provided only at one end of the cover member 4 in the longitudinal direction, or may be provided at any other position on the cover member 4.

4. Bottom structure of log house Although not shown in FIG. 1, the bottom surface of log house 2 is formed in advance by log material 21 or other members, and a living space surrounded by the bottom surface, side surfaces, and top surface is inside the log house 2. Is formed in. The completed log house 2 is lifted by a crane using the hook member 45 and placed on the chassis body 31 from above. The log house 2 may be attached to the chassis main body 31 after being painted in advance.

However, the configuration is not limited to the above, and the bottom surface of the log house 2 may be provided on the chassis body 31. In this case, the log house 2 is lifted in an unfinished state without a bottom surface, and is placed on the chassis main body 31 to form a bottom surface to complete the log house 2. FIG. 5 is a schematic vertical sectional view showing an example of the bottom structure of the log house 2.

In the example of FIG. 5, the bottom plate 34 is attached to the chassis body 31. The chassis body 31 is formed by, for example, framed a frame 312 made of C-shaped steel (groove-shaped steel) or H-shaped steel in a rectangular shape. The bottom plate 34 is fixed to the lower surface of the frame 312 by welding or the like. However, the bottom plate 34 may be fixed to the upper surface of the frame 312.

The bottom plate 34 is a plate-shaped member having a plurality of ventilation holes 341. The bottom plate 34 can be made of, for example, a net-like plate or a punching plate. The living space 20 in the log house 2 and the outside are ventilated through a plurality of ventilation holes 341 formed in the bottom plate 34. However, the bottom plate 34 may have a configuration in which the ventilation holes 341 are not formed.

A heat insulating material 35 is installed on the bottom plate 34. The material of the heat insulating material 35 is not particularly limited, and may be a fiber-based heat insulating material such as glass wool or rock wool, or a resin-based heat insulating material such as polystyrene foam or urethane foam. Good. The thickness of the heat insulating material 35 may be about the same as the thickness of the chassis body 31 (frame 312) as shown in FIG. 5, but is not limited to this. Further, although not shown, a flooring material may be separately provided on the upper surface of the heat insulating material 35.

The chassis body 31 and the log house 2 are fixed by using a fixture 36 such as a bolt, for example. The fixture 36 may be composed of through bolts that penetrate a plurality of assembled log materials 21 from the upper end to the lower end. In this case, the upper end of the fixture 36 may be formed by a plate-shaped head, and the lower end may penetrate the through hole 313 formed on the upper surface of the frame 312 and be tightened with a nut. As a result, the plurality of assembled log materials 21 can be sandwiched between the fixtures 36 and firmly connected. The fixture 36 may be appropriately provided not only at the four corners of the log house 2 but also at any other position as shown in FIG. For example, a stainless steel foundation packing 37 is sandwiched between the log material 21 and the chassis body 31 (frame 312).

In this way, another member can be arranged between the log material 21 and the chassis body 31. For example, the foundation packing 37 as described above may be further provided with a base member (square lumber), or any other member may be arranged. Further, as shown by the alternate long and short dash line in FIG. 5, it is also possible to insert the sheet metal 38 as needed to further strengthen the fixing between the log material 21 and the chassis body 31.
