Description

[Technical Field]

[0001] This invention relates to a hexagonal trailer house that includes a chassis having a connection part that can be freely connected to a towing vehicle and a plurality of wheels, and a house that is hexagonal in plan view and is loaded onto the chassis. [Background technology]

[0002] BACKGROUND ART Conventionally, there have been trailer houses that are sufficiently long in the front-to-rear direction (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7676625 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the shape of a trailer house is hexagonal when viewed from above, the front-to-back dimensions will be shorter than those of conventional configurations, and considering livability, it is desirable to make the roof shape conical (hexagonal pyramid) in order to ensure a certain level of height. In this case, the roof portion in particular is susceptible to headwinds and crosswinds in the direction of travel while the trailer house is being towed, which may cause the trailer house to become unstable.

[0005] Therefore, the present invention solves the problems of the prior art as described above. In other words, the purpose of the present invention is to provide a hexagonal trailer house that stabilizes the posture of the trailer house when towing it while moving, and that allows for a larger living space inside the trailer house when set up compared to when towed. [Means for solving the problem]

[0006] The invention according to claim 1 is a hexagonal trailer house comprising a chassis having a connection part that can be freely connected to a towing vehicle and a plurality of wheels, and a house that is hexagonal in plan view and is loaded onto the chassis, wherein the house comprises a floor part, side walls that are hexagonal in plan view, a flat first roof part for use during transportation, and a conical second roof part for use during construction, the first roof part for use during transportation being detachable from the hexagonal side walls in plan view, and the second roof part for use during construction being comprised of a single support part that is arranged in the center of the house and is extendable in the height direction, and a support part that is extendable in the height direction and is attached to the upper end side of the support part. The tent has six ascending beam sections arranged radially and that can be opened and closed freely, and a hexagonal pyramidal sheet section arranged above the six ascending beam sections, and when the second roof section for setup is closed, the support sections, ascending beam sections, and hexagonal pyramidal sheet sections are more compact than the inner dimensions of the hexagonal side wall sections in a planar view, and when the second roof section for setup is open, the ascending beam sections and hexagonal pyramidal sheet sections are wider than the inner dimensions of the hexagonal side wall sections in a planar view, thereby solving the above-mentioned problem.

[0007] The invention of claim 2 further solves the above-mentioned problem by configuring the lower end of the support pillar portion to be detachable from the floor portion in addition to the configuration of the hexagonal trailer house described in claim 1.

[0008] The device of claim 3 further solves the above-mentioned problem by having a sliding mechanism between the first roof section for use during transportation and the side wall section that is hexagonal in plan view, in addition to the configuration of the hexagonal trailer house described in claim 1 or claim 2, and by configuring the first roof section for use during transportation to be freely slidable relative to the side wall section that is hexagonal in plan view.

[0009] The invention of claim 4 further solves the above-mentioned problem by configuring the chassis to have three wheels, in addition to the hexagonal trailer house configuration described in claim 3, and by configuring the three wheels in a triangular positional relationship.

[0010] The invention of claim 5 further solves the above-mentioned problem by configuring the hexagonal trailer house as described in claim 4, and by configuring the side wall portion of the hexagonal shape in plan view to have at least two swingable door portions.

[0011] The invention of claim 6 further solves the above-mentioned problem by, in addition to the configuration of the hexagonal trailer house described in claim 5, configuring the house so that it can be attached and detached freely from the chassis. [Effects of the Invention]

[0012] The hexagonal trailer house of this invention is equipped with a chassis with a connection part that can be freely connected to a towing vehicle and multiple wheels, and a house that is hexagonal in plan view and is loaded onto the chassis.This not only allows it to be connected to a towing vehicle and moved, or parked and set up, but it also has the following unique effects.

[0013] According to the hexagonal trailer house of the invention of claim 1, when towing during transport, the second roof section for use during setup is stored inside the trailer house, and the first roof section for use during transport is placed over the top of the trailer house, thereby reducing the impact of headwinds and crosswinds in the direction of travel during towing, thereby stabilizing the posture of the trailer house. On the other hand, when set up, the first roof section for use during transportation is removed from the top of the trailer house, and the second roof section for use during setup, which was stored inside the trailer house, moves upward and opens due to the extension of the support pillars, covering the top of the trailer house, thereby increasing the living space inside the trailer house compared to when it is towed. In this case, the second roof section for setup moves upward by extending the support pole, so the second roof section for setup can be easily set up by simply spreading it out and placing it over the top of the hexagonal side wall section when viewed from above. Furthermore, when storing the second roof section for use during setup, the second roof section for use during setup is first lifted away from the upper end of the hexagonal side wall section in a plan view, and then closed, so that the support section, ascending beam section, and hexagonal pyramidal sheet section become more compact than the inner dimensions of the hexagonal side wall section in a plan view.As a result, the support section can be reduced in size, and the second roof section for use during setup can be moved downward and easily stored inside the trailer house. Additionally, because they are easy to move and set up, trailer homes can be used in the event of a disaster. Furthermore, the second roof section used when setting up has a hexagonal pyramidal sheet portion, and compared to a structure made of wood like the side wall sections, it is lightweight and can be opened and closed freely like an umbrella, which reduces the weight of the entire house and lowers the center of gravity, ensuring stability when towing.

[0014] According to the hexagonal trailer house of the invention of claim 2, in addition to the effect of the invention of claim 1, when setting up, the second roof section for use during setting up is moved upward and opened by the extension of the support section, and then the lower end of the support section can be separated from the floor section and can be freely contracted upward, so that the support section can be moved to a position higher than the user's head to prevent it from getting in the way of living. On the other hand, when storing the second roof section for setup, the lower ends of the support poles are extended downward and brought into contact with the floor, thereby supporting the second roof section for setup on the floor, and the second roof section for setup can be lifted away from the upper ends of the hexagonal side wall sections in a plan view, and then easily closed.

[0015] According to the hexagonal trailer house of the invention of claim 3, in addition to the effects achieved by the invention of claim 1 or claim 2, when changing the roof from the first roof section for use during transportation to the second roof section for use during setup, the first roof section for use during transportation can be slid and moved to the outside of the hexagonal side wall section in a plan view, eliminating the need to lift it up and lower it to the ground, so the roof can be easily changed from the first roof section for use during transportation to the second roof section for use during setup and set up. On the other hand, when changing the roof from the second roof section for setup to the first roof section for transport, the second roof section for setup is stored and then the first roof section for transport can be slid freely while being supported by the upper end of the hexagonal side wall section in a plan view, so the roof can be easily changed from the second roof section for setup to the first roof section for transport and then removed.

[0016] According to the hexagonal trailer house of the invention of claim 4, in addition to the effect achieved by the invention of claim 3, the chassis and house are supported by the ground at three points, so the posture of the house can be stabilized while being towed or set up.

[0017] According to the hexagonal trailer house of the invention of claim 5, in addition to the effect achieved by the invention of claim 4, multiple trailer houses can be arranged next to each other like a honeycomb in a plan view, and the doors allow free movement between the multiple trailer houses and also allow free entry and exit to the outside, so multiple rooms can be easily created by arranging multiple trailer houses next to each other. Furthermore, by setting up multiple trailer homes next to each other in an evacuation shelter such as a gymnasium, multiple rooms can be created, making the trailer homes a convenient shelter in the event of a disaster.

[0018] According to the hexagonal trailer house of the invention of claim 6, in addition to the effect of the invention of claim 5, the house can be removed from the chassis and placed on the ground in a gymnasium, garden, garage, etc., making it easy to set up a personal room such as a hobby room in a garden or garage. Additionally, trailer homes can be used in the event of a disaster because they are easy to set up in evacuation shelters such as gymnasiums. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] The hexagonal trailer house of this invention comprises a chassis with a connection part that can be freely connected to a towing vehicle and a plurality of wheels, and a house that is hexagonal in plan view and is loaded onto the chassis. The house has a floor part, side walls that are hexagonal in plan view, a flat first roof part for use during transportation, and a conical second roof part for use during construction. The first roof part for use during transportation is detachable from the hexagonal side walls in plan view, and the second roof part for use during construction is disposed in the center of the house and is extendable in the height direction. The tent has one support pole, six ascending beams arranged radially from the upper end of the support pole and capable of being opened and closed, and a hexagonal pyramidal sheet arranged above the six ascending beams. When the second roof section for construction is closed, the support pole, the ascending beam, and the hexagonal pyramidal sheet are smaller in size than the inner dimensions of the side wall, which is hexagonal in plan view. When the second roof section for construction is open, the ascending beams and the hexagonal pyramidal sheet are smaller in size than the inner dimensions of the side wall, which is hexagonal in plan view. However, because the second roof section for setup is wider than the inner dimensions of the hexagonal side wall sections when viewed from above, the trailer house can be stabilized when towed while in motion, and when set up, the living space inside the trailer house can be expanded compared to when towed.The second roof section for setup can be easily set up by simply unfolding it and placing it over the upper ends of the hexagonal side wall sections when viewed from above.Furthermore, when storing the second roof section for setup, the support part can be shortened and the second roof section for setup can be moved downward and easily stored inside the trailer house, allowing the trailer house to be used in the event of a disaster.Compared to a configuration in which the second roof section for setup is made of wood like the side wall sections, the weight of the entire house can be reduced and the center of gravity can be lowered, and stability when towed can be ensured.The specific embodiment is not limited to this as long as it is possible to reduce the weight of the house as a whole and lower the center of gravity, and ensure stability when towed.

[0021] For example, the material for the floor and side walls of the house may be wood or resin such as reinforced plastic. Furthermore, the material of the first roof portion for use during transportation may be metal, resin such as reinforced plastic, or wood. Furthermore, the material for the support pillars and the ascending beams of the second roof section for use when erecting the tent may be wood, metal, or resin such as reinforced plastic. Furthermore, the material for the hexagonal pyramidal sheet portion of the second roof section used during setup needs to be able to be freely folded and deformed depending on whether the second roof section used during setup is opened or closed, and can be any material, such as tarpaulin (a high-strength vinyl sheet made from polyester fibers processed with a synthetic resin film) used as a fire-resistant and flame-retardant sheet. As for the number of wheels on the chassis, as a general concept, it is sufficient that there is more than one, and it may be two or three. Furthermore, the side wall portion of the house basically has one or more door portions, but as a general concept, the number of door portions may be any number. [Example]

[0022] A hexagonal trailer house 100 according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 6(B). Here, Figure 1 is a perspective view showing the concept of a hexagonal trailer house 100 which is an embodiment of the present invention, Figure 2(A) is a side view of the hexagonal trailer house 100 which is an embodiment of the present invention when the first roof section 123 for use during transportation is covering the upper end of the side wall section 122 which is hexagonal in plan view, Figure 2(B) is a plan sectional view of the trailer house 100 as seen at 2B-2B in Figure 2(A), Figure 3(A) is a view showing the state when the first roof section 123 for use during transportation of the hexagonal trailer house 100 which is an embodiment of the present invention swings and is removed from the upper end of the side wall section 122 which is hexagonal in plan view, Figure 3(B) is a view showing the state when the first roof section 123 for use during transportation of the hexagonal trailer house 100 which is an embodiment of the present invention is removed and slid downward, Figure 4(A) is a view of the hexagonal trailer house 100 which is an embodiment of the present invention when the first roof section 123 for use during transportation is covering the upper end of the side wall section 122 which is hexagonal in plan view, FIG. 4(B) is a diagram showing the second roof section 124 for use during setup being moved upward and opened, and FIG. 4(B) is a diagram showing the second roof section 124 for use during setup of the hexagonal trailer house 100, an embodiment of the present invention, being placed over the upper end of the hexagonal side wall section 122 in a plan view. FIG. 5(A) is a conceptual plan view showing six hexagonal trailer houses 100, an embodiment of the present invention, arranged adjacent to each other in a honeycomb pattern. FIG. 5(B) is a conceptual plan view showing seven hexagonal trailer houses 100, an embodiment of the present invention, arranged adjacent to each other in a honeycomb pattern. FIG. 6(A) is a diagram showing the house 120 of the hexagonal trailer house 100, an embodiment of the present invention, being lifted from the chassis 110, and FIG. 6(B) is a diagram showing the house 120 of the hexagonal trailer house 100, an embodiment of the present invention, being placed directly on the ground after being lifted.

[0023] As shown in Figures 1 to 4(B), the hexagonal trailer house 100, which is an embodiment of the present invention, comprises a chassis 110 having a connection part 111 that can be freely connected to a towing vehicle and a plurality of wheels 112, and a house 120 that is hexagonal in plan view and is loaded on the chassis 110. Of these, house 120 comprises floor portion 121, side wall portion 122 that is hexagonal in plan view, flat first roof portion 123 for use during transportation, and conical second roof portion 124 for use during construction. A floor 121 and a side wall 122 of the house 120 are formed of wood, for example, and the house 120 is a so-called log house.

[0024] For example, the logs are assembled by fitting the tip ends of the logs together so that the tip surface of one log does not protrude from the surface of the other log. Specifically, each log has a recessed stepped surface at both ends of its tip end. Then, the logs are stacked one on top of the other in order so that the stepped surfaces formed on the tip surfaces of adjacent logs abut against each other, and the multiple logs interlock with each other at their stepped surfaces, firmly connecting them together. If the step surface is formed in a wedge shape, the logs can be connected more firmly. When formed in this manner, the house 120 becomes a log house with notchless corners.

[0025] Furthermore, in this embodiment, the first roof portion 123 for use during movement is detachable from the side wall portion 122 which is hexagonal in plan view. The first roof portion 123 for use during transportation is formed, for example, from a galvalume steel plate (registered trademark) with a heat-resistant coating.

[0026] The second roof section 124 for use during construction has one support section 124a, six ascending beam sections 124b, and a hexagonal pyramidal sheet section 124c. Of these, the support portion 124a is disposed in the center of the house 120 and is configured to be extendable and contractible in the height direction. The support portion 124a is configured such that, for example, a plurality of cylindrical shafts of different diameters are provided, like a folding umbrella or a fishing rod, and the shafts are provided so as to be extendable and retractable in multiple stages in the extending direction. The ascending beam portions 124b are disposed radially from the upper end side of the support portion 124a and are provided so as to be able to open and close freely.

[0027] The ascending beam portion 124b is configured to be able to open and close freely by swinging relative to the upper end side of the support portion 124a like a parasol or umbrella. The hexagonal pyramidal sheet portion 124c is disposed above the six ascending beam portions 124b and is provided so as to open and close in a manner that widens and narrows as the ascending beam portions 124b open and close. The hexagonal pyramidal sheet portion 124c is formed, for example, from tarpaulin, which is a flame-resistant canvas.

[0028] As shown in Figures 2(A) to 4(A), when the second roof section 124 for setup is closed, the support section 124a, the ascending beam section 124b, and the hexagonal pyramidal sheet section 124c are more compact than the inner dimensions of the side wall section 122, which is hexagonal in plan view. On the other hand, as shown in Figures 4(A) to 4(B), when the second roof section 124 for setup is open, the ascending beam section 124b and the hexagonal pyramidal sheet section 124c are configured to be wider than the inner dimensions of the hexagonal side wall section 122 when viewed from above.

[0029] As a result, as shown in Figures 2(A) to 2(B), when the trailer house is towed during travel, the second roof section 124 for use during setup is stored inside the trailer house 100, and the first roof section 123 for use during travel is placed over the top of the trailer house 100, thereby reducing the effects of headwinds and crosswinds in the direction of travel during towing. As a result, the posture of the trailer house 100 can be stabilized. On the other hand, as shown in FIGS. 3(A) and 3(B), in the pitched state, the first roof section 123 for travel is removed from the top of the trailer house 100. Then, as shown in Figures 4(A) to 4(B), the second roof section 124 for setup, which was stored inside the trailer house 100, moves upward and opens due to the extension of the support section 124a, thereby covering the top of the trailer house 100. As a result, the living space inside the trailer house 100 can be increased compared to when the trailer house 100 is towed. At this time, the second roof section 124 for setup is moved upward by extending the support section 124a. As a result, the tent can be easily set up by simply unfolding the second roof portion 124 for use during setup and placing it over the upper ends of the side wall portions 122, which are hexagonal in plan view. In this case, a hook may be provided on the periphery of the hexagonal pyramidal sheet portion 124c and fastened to the upper end of the side wall portion 122, thereby locking the second roof portion 124 for setup to the side wall portion 122.

[0030] Furthermore, when storing the second roof section 124 for setup, the second roof section 124 for setup is first lifted away from the upper end of the hexagonal side wall section 122 when viewed from above, so as to change from the state shown in Figure 4(B) to the state shown in Figure 4(A), and then closed, so that the support section 124a, the ascending beam section 124b, and the hexagonal pyramidal sheet section 124c become more compact than the inner dimensions of the hexagonal side wall section 122 when viewed from above. As a result, the support portion 124a can be retracted to move the second roof portion 124 for setup downward from the state shown in Figure 4(A) to the state shown in Figure 3(B), and the second roof portion 124 can be easily stored inside the trailer house 100.

[0031] Furthermore, since the trailer house 100 is easy to move and set up, it can be used in the event of a disaster. Furthermore, the second roof section 124 for use during setup has a hexagonal pyramidal sheet section 124c, and compared to a configuration made of wood like the side wall sections 122, it can be opened and closed freely like an umbrella and is lightweight. As a result, the weight of the entire house 120 can be reduced and the center of gravity can be lowered, ensuring stability when towing.

[0032] Furthermore, in this embodiment, the lower end 124aa of the support portion 124a is configured to be detachable from the floor portion 121. For example, the lower end 124aa of the support portion 124a may be configured to be detachable from an engagement hole provided in the floor portion 121. The engagement hole provided on the floor portion 121 doubles as a weight and may be movable. For example, when the second roof section 124 for setup is closed, it is positioned in the center of the floor section 121, and when the second roof section 124 for setup is open and the ascending beam section 124b and the hexagonal pyramidal sheet section 124c are placed over the upper end of the side wall section 122, and the support section 124a is contracted upward, the engagement holes are no longer necessary, so the engagement holes that also serve as weights may be moved to the corners of the floor section 121.

[0033] As a result, when setting up, the second roof section 124 for setting up is moved upward and opened by the extension of the support section 124a so as to change from the state shown in FIG. 3(B) to the state shown in FIG. 4(A). Thereafter, the lower end 124aa of the support portion 124a is separated from the floor portion 121, so that the support portion 124a can freely contract upward from the state shown in FIG. 4(A) to the state shown in FIG. 4(B). As a result, the support portion 124a can be moved to a position higher than the user's head, preventing it from becoming an obstacle to living.

[0034] On the other hand, when storing the second roof section 124 for setup, the lower end 124aa of the support section 124a is extended downward and brought into contact with the floor section 121, so that the second roof section 124 for setup is supported by the floor section 121, changing from the state shown in Figure 4(B) to the state shown in Figure 4(A). As a result, as shown in FIG. 4(A), the second roof section 124 for setup can be lifted away from the upper end of the side wall section 122, which is hexagonal in plan view, and then easily closed. The lower side of the support portion 124a may be configured to be detachable from the upper side.

[0035] In this embodiment, as shown in FIGS. 3(A) and 3(B), a slide mechanism 125 is provided between the first roof portion 123 for movement and the side wall portion 122 that is hexagonal in plan view. The first roof portion 123 for use during movement is configured to be slidable relative to the side wall portion 122 which is hexagonal in plan view. The slide mechanism 125 may be configured, for example, by providing a convex portion on one side of the side wall portion 122 and a concave rail portion on the other side of the first roof portion 123 for movement, so that the convex portion and the concave rail portion slide while engaging with each other.

[0036] This means that when changing the roof from the first roof section 123 for transport to the second roof section 124 for setup, the first roof section 123 for transport can be slid to the outside of the hexagonal side wall section 122 in a plan view to change from the state shown in Figure 2(A) to the state shown in Figure 3(B), eliminating the need to lift it up and lower it to the ground. As a result, the roof can be easily changed from the first roof section 123 for use during transportation to the second roof section 124 for use during construction and then constructed.

[0037] On the other hand, when changing the roof from the second roof section 124 for setup to the first roof section 123 for transportation, after the second roof section 124 for setup is stored, the first roof section 123 for transportation can be slid freely while being supported by the upper end of the hexagonal side wall section 122 in a plan view, so as to change from the state shown in Figure 4(A) to the state shown in Figure 3(B), and from the state shown in Figure 3(B) to the state shown in Figure 2(A). As a result, the roof can be easily changed from the second roof section 124 for construction to the first roof section 123 for transportation and then removed.

[0038] Furthermore, in this embodiment, the chassis 110 has three wheels 112 as shown in FIG. 2(B). The three wheels 112 are arranged in a triangular positional relationship. This allows the chassis 110 and the house 120 to be supported at three points by the ground. As a result, compared to a configuration in which the house 120 is supported at two points, the posture of the house 120 can be stabilized while being towed or set up.

[0039] In this embodiment, as shown in FIG. 2(B), the side wall portion 122, which is hexagonal in plan view, has at least two swingable door portions 122a. As a result, as shown in Figures 5(A) to 5(B), multiple trailer houses 100 are arranged next to each other in a honeycomb-like configuration in a plan view, and the door portions 122a allow free movement between the multiple trailer houses 100 and also allow free entry and exit to the outside. As a result, a plurality of rooms can be easily configured by arranging a plurality of trailer houses 100 next to each other. Furthermore, in an evacuation shelter such as a gymnasium, multiple rooms can be formed by setting up multiple trailer houses 100 next to each other. As a result, the trailer house 100 can be used as a convenient shelter in the event of a disaster.

[0040] Furthermore, in this embodiment, as shown in FIGS. 6(A) and 6(B), the house 120 is configured to be detachable from the chassis 110. This allows the house 120 to be detached from the chassis 110 and placed freely on the ground in a gymnasium, a garden, a garage, or the like. As a result, you can easily set up your own room, such as a hobby room, in your garden or garage. It also makes it easier to set up in evacuation shelters such as gymnasiums. As a result, the trailer house 100 can be used in the event of a disaster.

[0041] In addition, a foundation packing 121a is provided on the underside of the floor portion 121 of the house 120. A plurality of base packings 121a are arranged at intervals from each other. This improves ventilation under the floor 121 of the house 120, that is, between the house 120 and the chassis 110, or between the house 120 and the ground. As a result, even if the house 120 is a log house in which the floor 121 and side wall 122 are made of wood and the floor 121 has absorbed a lot of moisture due to rain or humidity in the air, the floor 121 can be dried appropriately.

[0042] Further, the chassis 110 is provided with a protrusion 113 . On the other hand, the house 120 is provided with a recess (not shown) that can be engaged with the protrusion 113 of the chassis 110 . As a result, when the house 120 is placed on the chassis 110, the convex portion 113 of the chassis 110 engages with the concave portion (not shown) of the house 120, and the two are positioned relative to each other. As a result, it is possible to prevent the positional relationship of the house 120 with respect to the chassis 110 from being displaced when the vehicle is towed.

[0043] The hexagonal trailer house 100 thus obtained as an embodiment of the present invention comprises a chassis 110 having a connection part 111 that can be freely connected to a towing vehicle and a plurality of wheels 112, and a house 120 that is hexagonal in plan view and is loaded onto the chassis 110. The house 120 comprises a floor part 121, side wall parts 122 that are hexagonal in plan view, a flat first roof part 123 for use during transportation, and a conical second roof part 124 for use during construction, and the first roof part 123 for use during transportation is detachable from the side wall parts 122 that are hexagonal in plan view, and the second roof part 124 for use during construction is detachable from the side wall parts 122 that are hexagonal in plan view. The roof section 124 has one support section 124a arranged in the center of the house 120 and freely expandable in the height direction, six ascending beam sections 124b arranged radially from the upper end side of the support section 124a and freely openable and closable, and a hexagonal pyramidal sheet section 124c arranged above the six ascending beam sections 124b, and when the second roof section 124 for setup is closed, the support section 124a, the ascending beam section 124b, and the hexagonal pyramidal sheet section 124c are more compact than the inner dimensions of the side wall section 122, which is hexagonal in plan view. When the second roof section 124 for setup is open, the ascending beam section 124b and the hexagonal pyramidal sheet section 124c are configured to be wider than the inside dimensions of the side wall section 122, which is hexagonal in plan view, so that the posture of the trailer house 100 can be stabilized when towing during travel, and on the other hand, in the setup state, the living space inside the trailer house 100 can be expanded compared to when towing, and the second roof section 124 for setup can be placed so as to cover the upper end of the side wall section 122, which is hexagonal in plan view, simply by unfolding it. Furthermore, when storing the second roof section 124 for use during setup, the support pillars 124a can be contracted and the second roof section 124 for use during setup can be moved downward and stored easily inside the trailer house 100, allowing the trailer house 100 to be used in the event of a disaster.Compared to a configuration in which the second roof section 124 for use during setup is made of wood like the side wall sections 122, the weight of the entire house 120 can be reduced and the center of gravity can be lowered, ensuring stability when towing.

[0044] Furthermore, since the lower end 124aa of the support portion 124a is configured to be detachable from the floor portion 121, when setting up the tent, the support portion 124a can be moved to a position higher than the user's head to prevent it from getting in the way of living in the tent.On the other hand, when storing the second roof portion 124 for setting up the tent, the second roof portion 124 for setting up the tent can be lifted away from the upper end of the side wall portion 122, which is hexagonal in plan view, and then easily closed.

[0045] In addition, a slide mechanism 125 is provided between the first roof section 123 for use during transportation and the side wall section 122 which is hexagonal in plan view, and the first roof section 123 for use during transportation is configured to be able to slide freely relative to the side wall section 122 which is hexagonal in plan view. Therefore, when changing the roof from the first roof section 123 for use during transportation to the second roof section 124 for use during setup, the roof can be easily changed from the first roof section 123 for use during transportation to the second roof section 124 for use during setup and then set up; on the other hand, when changing the roof from the second roof section 124 for use during setup to the first roof section 123 for use during transportation, the roof can be easily changed from the second roof section 124 for use during setup to the first roof section 123 for use during transportation and then taken down.

[0046] Furthermore, the chassis 110 has three wheels 112, and the three wheels 112 are arranged in a triangular positional relationship, which makes it possible to stabilize the posture of the house 120 while it is being towed or set up.

[0047] Furthermore, since the side wall portion 122, which is hexagonal when viewed from above, has at least two swingable door portions 122a, multiple trailer houses 100 can be arranged next to each other to easily create multiple rooms, and the trailer house 100 can be used as a convenient shelter in the event of a disaster.

[0048] Furthermore, since the house 120 is detachable from the chassis 110, it is possible to easily set up a personal room such as a hobby room in a garden or garage, and the trailer house 100 can be used in the event of a disaster, which has significant advantages. [Explanation of symbols]
