Description

Technical Field

[0001] The present invention relates to a mobile house, and more particularly to a mobile house that can be easily adjusted in its installation position manually after being installed at a predetermined location.

Background Art

[0002] Conventionally, as a simple building used for offices, houses, warehouses, etc., for example, a house by a prefabrication method or the like is known. This type of house is easy to install and remove, and is used as a temporary office at a construction site or the like, a temporary house in case of disaster, or other temporary buildings. In this type of house, in order to facilitate the work of installing the house and changing the installation location, a mobile house provided with casters or the like to be movable is known.

[0003] For example, Patent Document 1 discloses that in a mobile simple house in which plate bodies forming a wall portion, a roof portion, and a floor portion are assembled into a box-shaped housing unit, moving wheels are attached to the four corners of the lower surface portion of the housing unit. Thereby, by using the wheels, the work of loading and unloading the mobile simple house onto a large trailer and the work of moving it on the ground can be easily performed.

[0004] Also, for example, Patent Document 2 discloses a mobile unit house provided with detachable wheels. The mobile unit house disclosed in the same document is provided with a plurality of through sheath tubes made of cylindrical straight tubes horizontally fixed to the bottom of the floor portion, and at each end of the through sheath tubes, a short rod-shaped axle rod of the detachable wheel is inserted and removed freely. Thereby, the mobile unit house can be easily moved and the installation position can be adjusted. And when the adjustment of the installation position is completed, the detachable wheels are removed from the through sheath tubes.

[0005]

Patent Document 1

[0006] However, the conventional mobile greenhouse described above had areas that needed improvement in order to facilitate relocation while maintaining safety.

[0007] Specifically, a mobile house equipped with wheels for movement at the four corners of its underside, such as the mobile temporary house disclosed in Patent Document 1, has the advantage of being easy to move. However, because it is easily moved by the rotation of the wheels, there is a problem that the house itself can easily move away from its installation location even when movement is not necessary. For example, there is a risk that the mobile house may move significantly from its designated installation location due to strong winds such as typhoons or tremors such as earthquakes.

[0008] To ensure the safety of such mobile greenhouses, it is conceivable to install fixing devices such as wheel chocks or securing members to prevent the wheels from rotating and moving, or to install fixing brackets or other devices to directly fix and support the greenhouse body to the ground.

[0009] However, in a configuration where the greenhouse body is fixed and supported by such fastening members and fixing brackets, the efficiency of moving the mobile greenhouse for position adjustment decreases. In other words, when moving the mobile greenhouse, it is necessary to remove the fixing brackets, and when the move is complete, it is necessary to attach the fixing brackets, etc., to fix the mobile greenhouse in place.

[0010] For example, when using a mobile house as a temporary office at a construction site, it is necessary to frequently change the office location in accordance with the progress of the construction process. Conventional mobile houses do not make the relocation process easy, so improvements are needed to make the relocation process easier in order to improve the efficiency of work at construction sites and other locations.

[0011] Furthermore, in the prior art disclosed in Patent Document 2, in order to change the installation position of a mobile greenhouse after it has been set up, it is necessary to lift the greenhouse using a lifting machine such as a jack and attach or detach the wheels, and this work is not easy.

[0012] For more details, in order to move a mobile modular house, first, the house body is jacked up using a jack or similar device, and the axle rods of the detachable wheels are inserted into both ends of the through-sheath pipe, and the detachable wheels are attached to the house body. Then, by lowering the jack, the house body becomes movable.

[0013] Once the mobile unit house is moved to the designated location, the house is jacked up again using a jack or similar device, the detachable wheels are removed from the through-sheath pipes, and then the jack is lowered to allow the lower end of the house body to touch the ground. Thus, in the mobile unit house disclosed in the document, it was necessary to jack up the house twice to attach and detach the detachable wheels in order to adjust the installation position.

[0014] This invention has been made in view of the above circumstances, and its purpose is to provide a mobile house that can be safely installed so as not to move even in the event of strong winds or earthquakes, and can be easily moved by hand to adjust its installation position when a change of location is necessary. [Means for solving the problem]

[0015] The mobile house of the present invention comprises a house body in which plate-like members constituting the floor, outer walls, and roof are assembled to form an interior space; bases provided at the four corners of the house body to support the house body; and wheel units provided on the outer walls at the four corners of the house body, wherein the wheel units are vertically movable wheels that move from above the bottom surface of the base to below the bottom surface to support the house body so as to be movable. The vehicle comprises a lifting device for manually raising and lowering the wheels, a base fixing device fixed to the outer wall, and a rotatable base provided on the base fixing device that can rotate parallel to the outer wall. to have The lifting device comprises a support cylinder fixed to the outer wall and extending in the vertical direction, a vertically movable support shaft inserted into the support cylinder and supporting the wheel at its lower end, and a jack lever provided on the support cylinder for inputting power to raise and lower the support shaft, the support cylinder being fixed to the rotating base. It is characterized by the following: [Effects of the Invention]

[0016] The mobile house of the present invention comprises a house body in which plate-like members constituting the floor, outer walls, and roof are assembled to form an interior space; a base provided at the four corners of the lower part of the house body to support the house body; and wheel units provided on the outer walls at the four corners of the house body. The wheel units have vertically movable wheels that move from above the bottom surface of the base to below the bottom surface to support the house body movably. As a result, even after the mobile housing has been installed, the house body can be supported by the wheels with a simple operation of lowering the wheels of the wheel units, allowing the mobile house to be easily moved and its installation position adjusted. Furthermore, after the mobile housing has been moved to a predetermined position, the house body can be supported by the base by raising the wheels of the wheel units. Therefore, the mobile house can be fixed to the installation surface and safely installed so that it does not move due to strong winds, earthquakes, etc.

[0017] Furthermore, according to the mobile greenhouse of the present invention, the wheel unit is equipped with a lifting device for manually raising and lowering the wheels, and the lifting device may include a support cylinder fixed to the outer wall and extending in the vertical direction, a support shaft inserted into the support cylinder and supporting the wheels at its lower end, and a jack lever provided on the support cylinder for inputting power to raise and lower the support shaft. This allows the user to easily raise and lower the greenhouse body by turning the jack lever, enabling efficient movement and safe installation of the mobile greenhouse.

[0018] Furthermore, according to the mobile greenhouse of the present invention, the lifting device may have a screw mechanism that transmits the power of the jack lever to the support shaft. With such a configuration, a compact and highly efficient lifting device can be obtained, and the user can easily raise and lower the greenhouse body and easily move the mobile greenhouse.

[0019] Further, according to the mobile house of the present invention, the lifting device may have a hydraulic mechanism that transmits the power of the jack lever to the support shaft. Even with such a configuration, a highly efficient lifting device capable of lifting the house body with a small force can be obtained. Therefore, the user can easily lift the house body and easily move the mobile house.

[0020] Further, according to the mobile house of the present invention, the wheel unit has a pedestal fixture fixed to the outer wall portion and a rotary pedestal provided on the pedestal fixture and rotatable parallel to the outer wall portion, and the support cylinder may be fixed to the rotary pedestal. With such a configuration, the support shaft can be raised and swiveled via the rotary pedestal, and the wheels and the support shaft can be further retracted upward. Therefore, when the mobile house is placed on a transport vehicle or the like for transportation, it is possible to prevent the wheels, the support shaft, etc. from contacting the side or rear aori of the loading platform of the transport vehicle. Therefore, a large mobile house having a size close to the size of the loading platform of the transport vehicle can be safely transported.

[0021] Further, the mobile house of the present invention may include a base frame horizontally provided along the four sides of the floor portion to support the house body, a support column erected from the base frame to support the side of the outer wall portion, and a wheel unit support member fixed to at least one of the base frame and the support column to support the wheel unit. Thereby, the wheel unit can safely support the load of the mobile house via the wheel unit support member. Therefore, even a mobile house after installation with desks, chairs, shelves and other furniture placed in the indoor space can be safely moved.

MODE FOR CARRYING OUT THE INVENTION

[0023] Hereinafter, the mobile house 1 according to the embodiment of the present invention will be described in detail based on the drawings. FIG. 1 is a perspective view of the mobile house 1 according to the embodiment of the present invention as seen from obliquely above to the left from the front. Referring to FIG. 1, the mobile house 1 is a building assembled by, for example, a prefabricated construction method or the like, and is used as a temporary office or a temporary storage at a construction site or a civil engineering site. The mobile house 1 may be used as a temporary housing when a house is destroyed by an earthquake, a landslide disaster, etc., or as a temporary housing when a dwelling or the like is temporarily required for other reasons.

[0024] The house main body 2 of the mobile house 1 is assembled from plate-like members constituting a floor portion 10, an outer wall portion 11, and a roof portion 12, and forms a shape such as a substantially rectangular parallelepiped shape or a substantially cubic shape, and an indoor space (not shown) is formed inside the house main body 2.

[0025] Furthermore, the roof section 12 of the house body 2 may be formed in a sloping shape, for example, it may be a shape in which two or more sloping surfaces are combined, such as a gable roof or a hip roof. Also, the roof section 12 may be a roof shape that has a curved section, such as a semi-circular roof.

[0026] The plate-like members constituting the floor section 10, exterior wall section 11, and roof section 12 can be general wood materials such as structural plywood, or metal materials such as galvanized steel sheets or other steel sheets. In addition, the floor section 10, exterior wall section 11, and roof section 12 may contain various insulation materials such as glass wool or polystyrene foam.

[0027] The house body 2, for example, has a door 14 on the front exterior wall 11 for entering and exiting the interior space. The door 14 may also be provided on the side and rear exterior wall 11. Furthermore, the house body 2, for example, has an openable and closable window 13 on the side exterior wall 11. The window 13 may also be provided on the front and rear exterior wall 11.

[0028] A base 15 is provided near the four lower corners of the house body 2 to support the house body 2. The base 15 is made of, for example, channel steel or other general structural lightweight steel or other steel frame material. The base 15 is fixed to the lower part of the foundation frame 16, which is provided below the floor 10 and supports the house body 2.

[0029] Figure 2 is a schematic front view of the mobile greenhouse 1, and Figure 3 is a schematic side view of the mobile greenhouse 1. Referring to Figures 1 to 3, wheel units 3 are provided near the four lower corners of the greenhouse body 2, each having vertically movable wheels 21 that support the mobile greenhouse 1 in a movable manner. Specifically, the wheel units 3 are provided at the lower part of the outer wall portions 11 on the front and rear sides of the greenhouse body 2.

[0030] The arrangement of the wheel units 3 on the front and rear outer walls 11 of the house body 2 has the advantage of facilitating the transport of the mobile house 1 by transport vehicles. Specifically, when transporting the mobile house 1 on the bed of a transport vehicle, the wheel units 3 do not come into contact with the side panels of the transport vehicle's bed, thus not interfering with transport, loading, or unloading operations.

[0031] Furthermore, when transporting the mobile greenhouse 1 by transport vehicle, the size of the mobile greenhouse 1 that can be transported is limited by the width of the cargo bed. In a configuration where the wheel units 3 are provided on the front and rear of the greenhouse body 2, the width of the greenhouse body 2 can be made close to the width of the cargo bed. In other words, the greenhouse body 2 can be made larger.

[0032] As shown by the dashed line in Figure 3, the wheel unit 3 may be provided, for example, on the outer wall portions 11 on both sides of the greenhouse body 2. In this configuration, the distance between the front and rear wheels 21 can be reduced. Therefore, the configuration in which wheel units 3 are provided on both sides of the greenhouse body 2 has the advantage that when the greenhouse body 2 is supported by the wheels 21 and moved, the bending moment near the center of the greenhouse body 2 can be kept small.

[0033] Figure 4 is a front view showing the schematic configuration of the wheel unit 3. As shown in Figure 4, the wheel unit 3 includes wheels 21 that support the mobile house 1 (see Figure 1) so as to be movable, and a lifting device 25 that supports the wheels 21 so as to be able to move up and down.

[0034] The wheel 21 is a caster made of, for example, rubber or other synthetic resin. Specifically, the wheel 21 is a swivel wheel that can change direction freely. That is, the wheel 21 is pivotally supported on the wheel support 23 via a bearing 24 such as a rolling bearing and a wheel axle 22, and the wheel support 23 is pivotally supported on the lower end of the support shaft 27 via a swivel bearing 28 such as a rolling bearing.

[0035] Since all the wheels 21 on the mobile greenhouse 1 are swivel wheels that can change direction freely, it becomes easy to adjust the direction of movement of the mobile greenhouse 1, which is supported and moved by the wheels 21. Therefore, the installation location of the mobile greenhouse 1 can be adjusted to an efficient and precise position.

[0036] The lifting device 25 is a device for manually raising and lowering the wheel 21, and includes a support cylinder 26 that extends in the vertical direction, a support shaft 27 that is inserted into the support cylinder 26 and supports the wheel 21 at its lower end, and a jack lever 29 for inputting power to raise and lower the support shaft 27.

[0037] The support cylinder 26 is a member formed from, for example, a carbon steel pipe, a stainless steel pipe, or other steel pipe or aluminum pipe, and is supported on the outer wall portion 11 (see Figure 1) via a rotating base 32 and base fixing device 30 so as to extend in the vertical direction. The support cylinder 26 is rotatable along the outer wall portion 11. Further details will be described later.

[0038] The support shaft 27 that supports the wheel 21 is made of steel, aluminum, or other various metal tubular or rod materials, and is inserted into the support cylinder 26 from its lower end, and is supported by the support cylinder 26 so as to be slidable in the vertical direction. That is, the support shaft 27 extends in the vertical direction and can change position in its axial direction, i.e., in the vertical direction.

[0039] The jack lever 29 is a rotary lever that is used to manually raise and lower the support shaft 27, and is located at the top of the support cylinder 26. By gripping and rotating the jack lever 29, the user can move the support shaft 27 vertically, thereby raising and lowering the wheels 21.

[0040] More specifically, the lifting device 25 has a power transmission mechanism (not shown) that transmits the power of the jack lever 29 to the support shaft 27. The power transmission mechanism may include, for example, a bevel gear (not shown) that transmits the rotation of the jack lever 29 to a jack shaft (not shown) that extends in the vertical direction. As a result, when the jack lever 29 is turned by the user's operation, the rotational power of the jack lever 29 is transmitted to the jack shaft via the meshing bevel gear, causing the jack shaft to rotate.

[0041] The jack lever 29 may also be directly connected to the upper end of the jack shaft so that it rotates coaxially with the jack shaft, i.e., horizontally. In that case, a bevel gear that meshes between the jack lever 29 and the jack shaft is unnecessary. When the jack lever 29 is turned by the user's operation, the rotational power of the jack lever 29 is directly transmitted to the jack shaft, which is mounted coaxially with the rotation axis of the jack lever 29, causing the jack shaft to rotate.

[0042] Furthermore, the lifting device 25 has a screw mechanism (not shown) that transmits the rotational power of the jack shaft to the support shaft 27. The screw mechanism may be configured such that, for example, a male thread is formed on the jack shaft and a female thread is formed on the support shaft 27 that screws onto the male thread, or conversely, a female thread is formed on the jack shaft and a male thread is formed on the support shaft 27.

[0043] Thus, the configuration with a screw mechanism allows the support shaft 27 to be efficiently raised and lowered by the rotational power of the jack shaft. Therefore, a compact and highly efficient lifting device 25 is obtained. The user can easily raise and lower the greenhouse body 2 by manually turning the jack lever 29, and easily move the mobile greenhouse 1.

[0044] Furthermore, the lifting device 25 may be provided with a power transmission mechanism to transmit power from the jack lever 29 to the support shaft 27, such as a gear mechanism like a rack and pinion (not shown), or a pulley, belt, chain, or other transmission element.

[0045] Furthermore, the lifting device 25 may have a hydraulic mechanism (not shown) as a power transmission mechanism for transmitting power from the jack lever 29 to the support shaft 27. For example, a hydraulic cylinder (not shown) may be formed inside the support cylinder 26, and a hydraulic piston (not shown) may be provided on the support shaft 27 to press and move the support shaft 27 by hydraulic pressure. In addition to a pressurizing piston (not shown) that reciprocates with the rotation of the jack lever 29 to supply oil and increase the hydraulic pressure inside the hydraulic cylinder, other components of the hydraulic mechanism may include a pressurizing cylinder for the pressurizing piston, hydraulic piping, a check valve, a valve, etc.

[0046] By employing a power transmission mechanism that uses hydraulics to raise and lower the support shaft 27, a highly efficient lifting device 25 is obtained that allows the greenhouse body 2 to be raised and lowered with minimal force. Therefore, the user can easily raise and lower the greenhouse body 2 and easily move the mobile greenhouse 1.

[0047] Figure 5(A) shows an example of a wheel 21 of the mobile house 1, and Figure 5(B) shows another example of a wheel 21. As shown in Figure 5(A), the wheel unit 3 may be provided with one wheel 21. That is, one wheel 21 is pivotally supported by the wheel support 23.

[0048] Furthermore, as shown in Figure 5(B), the wheel unit 3 may be a twin-wheel caster having two wheels 21. That is, two wheels 21 are pivotally supported by the wheel support 23. With this configuration, where two wheels 21 are provided on one wheel unit 3, the load of the heavy greenhouse body 2 can be safely supported by the two wheels 21 provided on each wheel unit 3. In addition, the rotation of the wheels 21 is also good. Therefore, the mobile greenhouse 1 can be moved efficiently and safely.

[0049] Figure 6 shows a schematic diagram of the mounting structure of the wheel unit 3 of the mobile house 1. Note that in Figure 6, the front outer wall portion 11 is omitted to show the support structure of the wheel unit 3. As shown in Figure 6, the mobile house 1 has a foundation frame 16 and support columns 17 that support the house body 2.

[0050] The foundation frame 16 is a member that supports the lower part of the house body 2 and is installed horizontally along approximately the four sides of the floor section 10. The support columns 17 are erected from the foundation frame 16 and support the vicinity of the side edges of the outer wall section 11. For the foundation frame 16 and support columns 17, for example, channel steel or lip channel steel for general structural use can be used.

[0051] The foundation frame 16 and the support columns 17 are provided with wheel unit support members 18 that support the wheel unit 3. The wheel unit support members 18 are formed from, for example, channel steel or lip channel steel for general structural use, and are fixed to the foundation frame 16 and the support columns 17 near the lower four corners of the house body 2 to connect and reinforce the foundation frame 16 and the support columns 17.

[0052] Specifically, the wheel unit support member 18 includes a wheel unit support column 19 erected from the foundation frame 16 and a wheel unit lateral support column 20 horizontally mounted from the support column 17. The wheel unit support column 19 is mounted approximately parallel to the support column 17, i.e., approximately perpendicular, and the wheel unit lateral support column 20 is mounted approximately parallel to the foundation frame 16, i.e., approximately horizontal. The wheel unit support column 19 and the wheel unit lateral support column 20 are connected and fixed by various fixing methods such as welding and screwing.

[0053] The wheel unit support member 18 has a base fixing device 30 for the wheel unit 3 fixed to it. More specifically, the base fixing device 30 is a component made of steel plate or the like, and is fixed to the wheel unit's horizontal support column 20, which connects the support column 17 and the wheel unit support column 19, by fixing screws 31 or welding.

[0054] As described above, wheel unit support members 18 are provided at the four lower corners of the house body 2, and the wheel unit 3 is fixed to the wheel unit support members 18. This allows the wheel unit 3 to safely support the load of the house body 2 via the wheel unit support members 18. In other words, the wheels 21 of the wheel unit 3 can safely support the mobile house 1 via the wheel unit support members 18. Therefore, the user can safely move the mobile house 1 even after it has been set up and furniture such as desks, chairs, shelves, etc., has been placed inside.

[0055] In the example above, the wheel unit support member 18 is fixed to both the foundation frame 16 and the support column 17, but the wheel unit support member 18 may also be fixed to only one of the foundation frame 16 or the support column 17.

[0056] For example, if the wheel unit 3 is located away from the corners of the house body 2 towards the center, the wheel unit 3 may be supported by a wheel unit support member 18 fixed only to the foundation frame 16, although this is not shown in the illustration. Even with such a configuration, the wheel unit 3 can be firmly attached to the house body 2 via the wheel unit support member 18 so as to be able to safely support the load of the house body 2.

[0057] Furthermore, various modifications can be made to the form of the wheel unit support member 18. For example, although not shown in the illustration, the wheel unit support column 19 may be provided at an angle so that one end is fixed to the foundation frame 16 and the other end is fixed to the support column 17. Also, although not shown in the illustration, a configuration in which the wheel unit lateral support column 20 is provided at an angle may be adopted.

[0058] Figure 7 shows a schematic diagram of the rotating base 32 of the wheel unit 3. As shown in Figure 7, the rotating base 32 is rotatably supported by the base fixing device 30 via a base bearing 33. Specifically, the rotating base 32 is made of a steel plate or the like and is pivotally supported approximately parallel to the base fixing device 30.

[0059] As described above, referring to Figures 6 and 7, the base fixing device 30 is fixed to the wheel unit support member 18 of the outer wall portion 11. Therefore, the rotating base 32 is provided to rotate approximately parallel to the outer wall portion 11. Since the support cylinder 26 of the wheel unit 3 is fixed to the rotating base 32, the support cylinder 26 can rotate approximately parallel to the outer wall portion 11.

[0060] The rotating base 32 is provided with a locking member 34 for maintaining the rotating base 32 in a predetermined rotational position. The locking member 34 is, for example, a locking member such as a pin or a bolt. The base fixing device 30 has a locking hole or the like formed therein into which the locking member 34 is inserted and fixed.

[0061] Figure 8 shows the vicinity of the wheel unit 3 of the mobile house 1 with the lifting device 25 of the wheel unit 3 rotated. As shown in Figure 8, the lifting device 25 of the wheel unit 3 is supported by a rotatable base fixing device 30, so that the support shaft 27 that supports the wheel 21 can rotate from a nearly vertical state to a nearly horizontal state.

[0062] Because the lifting device 25 is configured to be rotatable, the support shaft 27 can be raised and rotated via the rotating base 32, allowing the wheels 21 and support shaft 27 to be moved further upward.

[0063] This prevents the wheels 21, support shafts 27, etc. from coming into contact with the sides or rear tailgates of the transport vehicle when the mobile house 1 is loaded onto a transport vehicle or the like for transport. Therefore, a wide mobile house 1, which is close in width to the size of the transport vehicle's cargo bed, can be transported safely.

[0064] Furthermore, since the wheel unit 3 has a locking member 34 that locks the rotation of the base fixing device 30, the rotation of the lifting device 25 is locked by the locking member 34 when the support shaft 27 is approximately horizontal. As shown in Figure 6, even in the normal operating state when the support shaft 27 is approximately vertical, the rotation of the lifting device 25 is locked by the locking member 34. This ensures that the transport, installation, and post-installation position adjustment of the mobile house 1 are carried out safely.

[0065] Figure 9 shows the vicinity of the wheel unit 3, illustrating the movement of the mobile greenhouse 1. When moving the mobile greenhouse 1 to change its installation location, as shown in Figure 9, the wheels 21 are lowered below the bottom surface of the base 15, and the greenhouse body 2 is supported by the wheels 21.

[0066] Specifically, the wheel unit 3 has a lifting device 25 that supports the wheel 21 so that it can be raised and lowered, and the lifting device 25 is equipped with a jack lever 29 for manually raising and lowering the wheel 21. As a result, the user can easily raise and lower the house body 2 by turning the jack lever 29 by hand, enabling efficient movement and safe installation of the mobile house 1.

[0067] Even after the mobile house 1 has been installed, the house body 2 can be supported and raised by the wheels 21 through a simple operation of manually turning the jack lever 29 to lower the wheels 21, allowing the mobile house 1 to be easily moved and its installation position adjusted.

[0068] As described above, the mobile house 1 according to this embodiment can be easily moved by simple operation by the user without the need to use separate lifting equipment such as jacks or special material handling machinery such as forklifts. The user can easily change and adjust the installation location of the mobile house 1, once it has been set up in a predetermined location, to a suitable position.

[0069] Furthermore, after lowering the wheels 21 to move the mobile greenhouse 1 to a predetermined position, the wheels 21 can be raised by manually reversing the jack lever 29, thereby supporting the greenhouse body 2 with the base 15, as shown in Figure 6. Thus, the mobile greenhouse 1 can be fixed to the installation surface 35 and safely held in place so that it does not move due to strong winds such as typhoons or shaking such as earthquakes.
