Description

Technical Field

[0001] This invention relates to a camping house that expands camping space, and more specifically, to a multi-section camping house in which a secondary room is pulled out from the main room that forms the camping space to expand the camping space. The secondary support frame supporting the secondary room is connected to the main support frame supporting the main room in a folding manner to minimize the volume, thereby improving the convenience of movement and facilitating installation. Background Technology

[0002] Generally speaking, as modern people's living environment becomes more and more comfortable, their living standards improve, and they have more leisure time, more and more people are traveling to riversides, mountains, fields and other wilderness areas to enjoy leisure time away from the city.

[0003] However, due to the lack of accommodation facilities in tourist destinations, or the difficulty in utilizing accommodation facilities due to large crowds, and the high cost, an increasing number of people are bringing camping gear to travel as an alternative to accommodation facilities.

[0004] This type of camping allows for the enjoyment of free travel without being restricted by accommodation facilities or location, and also solves the problem of food and lodging in the wild. Tents can be pitched, or camping cabins equipped with various living facilities such as kitchens and bedrooms can be mounted on mobile frames such as trucks or trailers and moved around.

[0005] The campsites are categorized into self-propelled campervans and motorhomes that are towed by a drive unit, depending on whether they have a motor for mobility.

[0006] The campsite is equipped with a bed, sofa, storage cabinets, kitchen, and bathroom, which are sufficient for daily life and are easy to move.

[0007] However, behind the advantage of easily moving these living facilities, there are also the following disadvantages. When moving, in order to protect the various facilities set up on the road and protect the campsite from these obstacles, the size of the campsite cannot exceed the prescribed size. Therefore, it is difficult to create a spacious area, resulting in the inconvenience of a reduced movement path for living in the campsite.

[0008] One solution to this problem is to lengthen the campervan, similar to a trailer, to address the issue of limited interior space. However, this method not only increases manufacturing costs but also creates difficulties when driving the vehicle.

[0009] In addition, the actual purchase price and maintenance costs of the campsites are very high, and their usage frequency is limited. Therefore, despite their convenience, the financial burden of purchasing and using them is too heavy for individuals.

[0010] At the same time, the space of the camping house is limited by the shape it was originally designed for, so it is difficult to expand the space for setting up facilities after it is built, thus failing to create a comfortable camping experience.

[0011] Therefore, in order to solve the above problems, it is necessary to develop a camping house that overcomes the disadvantage of being limited to a small space due to considerations of mobility, so as to expand its internal space on the campsite to achieve a more convenient camping life. At the same time, its structure should be simplified and its manufacturing cost reduced, thereby lowering the threshold for camping life.

[0016] The problem that the invention aims to solve

[0017] To address the aforementioned problems, the present invention aims to provide a multi-section camping house, which extends the camping space by pulling out a secondary chamber from the main chamber forming the camping space. The secondary support for the secondary chamber is connected to the main support for the main chamber via a rotating hinge, thus enabling folding. Therefore, when moving the camping house to the campsite, its volume can be minimized, thereby improving the convenience of movement. When installing at the campsite, the secondary support is rotated downwards and the secondary chamber is pulled out, making it easy to install and allowing for comfortable camping in a spacious camping area.

[0018] Another object of the present invention is to provide a multi-section camping house, wherein an extension bracket is connected to the end of a sub-bracket in a folded manner via an extension hinge to support the sub-chamber, thereby reducing the length of the extension bracket to below the height of the main chamber, thus enabling the camping house to be moved without obstruction, and the fixing protrusion of the extension bracket is provided in the bracket fixing groove of the fixing column, thereby enabling the extension bracket and the sub-bracket to be fixed in a folded state.

[0019] Another object of the present invention is to provide a multi-section camping cabin in which the eaves forming the side walls of the secondary room are raised and opened up, and an extended floor set inside the eaves forms an additional floor surface, thereby increasing the sense of openness of the secondary room and improving the quality of camping. Even in the folded state, the height of the extended floor is lower than the height of the windows of the eaves, so the windows are not blocked and there is no feeling of oppression.

[0020] Another object of the present invention is to provide a multi-section camping house, wherein the roof located above the main room moves up and down along the lifting columns, thereby forming a layer wall of different heights with the floor of the main room to form an upper space, and as a single rotating shaft located on one side of the main room rotates, a chain connected to the lower part of the lifting columns causes all the lifting columns to rise and fall simultaneously, thereby facilitating the operation of the roof's up and down movement.

[0021] Another object of the present invention is to provide a multi-section camping house, wherein, as the lifting column rises, the upper lifting frame and the lower lifting frame, which rise and fall along the lifting groove of the fixed column, respectively raise the upper railing frame and the lower railing frame to a certain height while maintaining a distance, thereby forming a support set on the upper railing frame and the lower railing frame, thus preventing people living in the upper space of the floor from falling.

[0022] Methods for solving problems

[0023] To achieve the above objectives, the multi-section extended camping cabin of the present invention includes: a main room 100, which forms a camping space in a hollow interior, with a roof 140 at the top, the roof 140 being supported by vertically arranged fixed columns 110 and raised and lowered by lifting columns 120 arranged inside the fixed columns 110, and bed frames 130 folding vertically or horizontally arranged on both sides of the main room 100; and an auxiliary room 200, which is pulled out from the interior of the main room 100 to the outside to expand the camping space, the hollow interior communicating with the interior space of the main room 100, and having wheels 210 for movement at the bottom; a vertical lifting groove 111 and a fall arrestor 112 are formed in the fixed column 110, the fall arrestor 112 being formed at the lower part of the lifting column 120 and having a protrusion 1 that moves up and down along the lifting groove 111. 21. Contact is made to prevent the lifting column 120 from moving downward.

A plurality of supports 127 are attached to the upper railing frame 126 and the lower railing frame 124. These supports 127 are connected to the upper railing frames 126 and the lower railing frames 124 provided on other adjacent lifting columns 120. An upper lifting frame 123 and a lower lifting frame 122 are formed protrudingly on the lifting column 120. The upper lifting frame 123 contacts the upper railing frame 126 to raise and lower the upper railing frame 126. The lower lifting frame 122 contacts the lower railing frame 124 to raise and lower the lower railing frame 124. The lower railing frame 124 has a spaced space to allow the upper lifting frame 123 to pass through.

[0024] Additionally, the present invention includes: a main support 500 disposed at the lower part of the main chamber 100 and having a guide rail surface that contacts the chamber wheel 210, the main support 500 being located inside the fixed column 110 and having a hinge frame 510 connected to its outer end surface; and a secondary support 400 supporting the secondary chamber 200 from below and having a guide rail surface that contacts the chamber wheel 210, the secondary support 400 having a rotating hinge 410 connected to the hinge frame 510, thereby allowing the secondary support 400 to rotate on the hinge frame 510.

[0025] In addition, the present invention provides an extension bracket 420 that supports the sub-chamber 200 from below. The end of the sub-bracket 400 is folded by an extension hinge 421, and the upper part of the extension bracket 420 has a fixing protrusion 422 that protrudes outward. The fixing protrusion 422 is inserted into the bracket fixing groove 113 formed in the fixing post 110, so that the sub-bracket 400 and the extension bracket 420 are fixed in a folded state along the vertical direction.

[0026] Furthermore, the rotation hinge 410 of the sub-support 400 of the present invention is formed in an arc shape, and when the sub-support 400 is unfolded in the horizontal direction, the guide rail surface of the main support 500 and the guide rail surface of the sub-support 400 are formed to be at the same height.

[0027] Furthermore, in the sub-chamber 200 of the present invention, an extended floor 230 that unfolds outward to form a floor surface is provided inside the eaves 220 constituting the side wall of the sub-chamber 200, and the extended floor 230 includes: a floor wheel 231 that slides along a floor guide rail 240 formed in the lower part of the sub-chamber 200; and a folding plate 233 that is connected to the extended floor 230 by means of a floor hinge 234 to form a floor surface.

[0028] Furthermore, in this invention, the locking platform 232 formed on the floor wheel 231 engages and locks with the stop platform 250, which is formed at a height higher than the floor guide rail 240, so that the extended floor 230 is fixed in an unfolded state.

[0029] Furthermore, in this invention, the floor surface of the extended floor 230 in its unfolded state is formed to the same height as the floor surface of the sub-room 200, and the height of the folding plate 233 and the extended floor 230 in the folded state is lower than the height of the window 221 provided on the eaves 220.

[0030] Furthermore, a single rotating shaft 300 is provided on one side of the main chamber 100 of the present invention. The rotating shaft 300 is arranged in a horizontal direction, and a pair of first sprockets 310 and a pair of second sprockets 320 formed on the rotating shaft 300 outside the first sprockets 310 are formed thereon. A protrusion 121 is formed at the lower part of the lifting column 120. The protrusion 121 is used to fix the chain 330 in the state of being engaged with the first sprockets 310 or the second sprockets 320. When the single rotating shaft 300 is rotated, multiple lifting columns 120 rise and fall simultaneously.

[0031] Furthermore, the plurality of supports 127 of the present invention, which are respectively attached to the upper railing frame 126 and the lower railing frame 124, are arranged perpendicular to the upper railing frame 126 and the lower railing frame 124.

[0032] Furthermore, the distance between the upper railing frame 126 and the lower railing frame 124 of the present invention is the same as the distance between the upper lifting frame 123 and the lower lifting frame 122 when the lifting column 120 rises.

[0033] Invention Effects

[0034] The multi-section camping house according to the present invention has the following advantages: an auxiliary room is pulled outward from the main room that forms the camping space to expand the camping space; the auxiliary support of the auxiliary room is connected to the main support of the main room by a rotating hinge, so that it can be folded. Therefore, the size of the camping house can be minimized when moving it to the campsite, improving the convenience of movement. When installing at the campsite, the auxiliary support can be rotated downward and the auxiliary room pulled out, so it is easy to install and can be used for comfortable camping in a spacious camping space.

[0035] In addition, the present invention has the following advantages: the extension bracket is connected to the end of the sub-bracket in a folded manner by an extension hinge to support the sub-chamber. Therefore, the length of the extension bracket can be reduced to below the height of the main chamber, so that it can be moved without obstruction and conveniently. Furthermore, the fixing protrusion of the extension bracket is set in the bracket fixing groove of the fixing column, so that the extension bracket and the sub-bracket can be fixed in a folded state.

[0036] Furthermore, the present invention has the following advantages: as the eaves forming the side walls of the secondary room rise and open, the extended floor set on the inner side of the eaves forms an additional floor surface, thereby enhancing the sense of openness of the secondary room and improving the quality of camping. Moreover, even in the folded state, the height of the extended floor is set lower than the windows of the eaves, so the windows are not blocked and there is no feeling of oppression.

[0037] In addition, the present invention has the following advantages: the roof, which is located above the main chamber, moves up and down along the lifting columns, thereby forming an upper space through the layered walls of different heights from the floor of the main chamber. Furthermore, as a single rotating shaft located on one side of the main chamber rotates, the chain connected to the lower part of the lifting columns causes all the lifting columns to rise and fall simultaneously, thus making it easy to operate the up and down movement of the roof.

[0038] Furthermore, the present invention has the following advantages: as the lifting column rises, the upper lifting frame and the lower lifting frame, which rise and fall along the lifting groove of the fixed column, respectively raise the upper railing frame and the lower railing frame to a certain height while maintaining a distance, thus forming a support set in the upper railing frame and the lower railing frame to prevent people living in the upper space of the floor from falling.

[0052] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can readily implement the present invention.

[0053] In this invention, "front" indicates the direction in which the secondary chamber 200 is pulled out from the main chamber 100, and "rear" indicates the direction opposite to the direction in which the secondary chamber 200 is pulled out from the main chamber 100.

[0054] like Figures 1 to 13 As shown, the multi-section camping house according to the present invention is a multi-section extended camping house, which includes:

[0055] The main room 100 forms a camping space with a hollow interior. It has a roof 140 at the top, which is supported by vertically installed fixed columns 110 and can be raised and lowered by lifting columns 120 installed inside the fixed columns 110. Bed frames 130 that fold vertically or horizontally are provided on both sides of the main room 100. The secondary room 200 is pulled out from the interior of the main room 100 to the outside to expand the camping space. Its hollow interior communicates with the interior space of the main room 100. It has wheels 210 at the bottom for movement.

[0056] The purpose of the multi-section camping house of the present invention is to provide a camping house that can solve the problem of food and lodging at the campsite. It is moved to the campsite by being mounted on a mobile frame such as a vehicle or trailer and by generating its own power or receiving power from the outside. After arriving at the campsite, the multi-section camping house of the present invention is installed to create a living space for camping life.

[0057] The multi-section camping house of this invention is mounted on a movable frame. When moved, the structures that make up the camping house are folded and fixed inside to minimize its volume. Therefore, during the movement to the campsite, it can avoid collisions with obstacles such as trees and road signs that could cause damage to the camping house. Thus, not only is moving the camping house of this invention convenient, but the transportation process is also simplified.

[0058] Upon arrival at the campsite, the camping cabin is installed by pulling out and expanding its internal structure to increase the camping space. The camping cabin is designed to ensure better camping space and allows for expansion to minimize movement during transport. This allows for the installation of more camping equipment, a more spacious interior, and improved mobility, ultimately leading to a more comfortable camping experience.

[0059] According to the multi-section camping house of the present invention, multiple internal camping spaces can be formed and connected to each other, thereby expanding the space.

[0060] The invention includes: a main chamber 100 disposed on the outermost shell of the campsite to form its shape; and a secondary chamber 200 that can be pulled out from the interior of the main chamber 100 to the outside. When moving the campsite, the secondary chamber 200 can be inserted into and secured within the main chamber 100, thereby minimizing its size. Upon arrival at the campsite for installation, if the secondary chamber 200 is pulled out from the main chamber 100, the camping spaces inside the main chamber 100 and the secondary chamber 200 are interconnected, allowing for movement and creating a spacious camping area for a comfortable camping experience.

[0061] The main support 500, located at the lower part of the main chamber 100, forms a rigid frame to improve structural stability by supporting the main chamber 100 on the ground. The secondary support 400, supporting the secondary chamber 200, is connected to the end of the main support 500 in a folded manner. The secondary support 400 folds vertically or horizontally. When moving the campsite, it is fixed in a vertically folded state, which not only prevents the secondary chamber 200 from being pulled out but also minimizes its volume. Upon arrival at the campsite for installation, the secondary support 400 unfolds horizontally to form a frame supporting the secondary chamber 200, thus providing stable support.

[0062] The guide rail surface of the sub-support 400 is connected to the guide rail surface of the main support 500 without any height difference, so that the sub-chamber 200 can be pulled out smoothly and easily for installation without obstruction, and the folding along the vertical direction can facilitate transportation.

[0063] like Figures 1 to 7 As shown, the multi-section camping cabin according to the present invention includes a main room 100, which is located on the outermost shell of the multi-section camping cabin and forms its shape. The main room 100 is hollow inside, thus forming a camping space. Its interior can accommodate items needed for camping.

[0064] The main chamber 100 can be formed in the shape of a box, with an open front surface, allowing the secondary chamber 200 to be pulled out. When the secondary chamber 200 is pulled out, the open front surface makes the interior space of the secondary chamber 200 and the interior space of the main chamber 100 interconnected, thereby allowing free movement back and forth.

[0065] The front surface of the main chamber 100 can be opened entirely or partially, depending on the size of the secondary chamber 200.

[0066] An access door 150 is provided on the rear surface of the main chamber 100 for accessing the interior camping space. The access door may also be located on one side, but in one embodiment of the invention, it is shown on the rear surface. The access door 150 is preferably opened by rotating outwards to avoid camping equipment and the secondary chamber 200 within the interior space of the main chamber 100, but it can also be opened or closed using a structure such as a sliding door.

[0067] A roof 140 is provided on the upper part of the main room 100. The roof 140 is connected to the upper part of the lifting column 120 (described later) and rises and falls simultaneously with the lifting column 120. When the roof 140 rises, a layer wall 141 of different height from the floor of the main room 100 is formed, creating a space above the main room 100 like an attic, which can be used by campers to rest.

[0068] The wall 141 is horizontally positioned above the main chamber 100 and is separated from the floor of the main chamber 100. To create a spacious interior space in the main chamber 100, the height of the wall 141 is preferably higher than the height of the camper, but this can be adjusted taking into account the overall volume of the main chamber 100.

[0069] The layer wall 141 is a structure that divides the space of the main room 100. The lower part of the layer wall 141 forms the interior space, and the upper part of the layer wall 141 is connected to the outside, creating a space that feels open, like an attic.

[0070] For the safety of residents living in the space above the wall 141, railings can be formed when the roof 140 is raised to prevent falls.

[0071] The square-tube shaped fixing columns 110 supporting the main chamber 100 are vertically arranged at the corners of the main chamber 100. The fixing columns 110 are located on the outside of the main support 500 (described later) to maintain the shape of the main chamber 100 and to support the main chamber 100 and transfer the load to the ground even when a load is applied to the upper space of the roof 140 (described later).

[0072] The fixed column 110 is hollow inside, and a lifting column 120 (described later) capable of vertical movement is disposed within the hollow. An idler wheel 115 may be provided on the fixed column 110 to simultaneously raise and lower the lifting column 120. On one side of the main chamber 100, a horizontally arranged rotating shaft 300 (described later) may be provided, and an idler wheel 115 connected to the rotating shaft 300 via a chain 330 is provided on the other side of the main chamber 100 where the rotating shaft 300 is not located. The idler wheel 115 may be located on the upper part of the fixed column 110. However, the position of the idler wheel 115 is not limited to this; it can be located on the upper part of the protrusion 121.

[0073] A lifting groove 111 is formed along a vertical direction on one side of the fixed column 110. The lifting groove 111 extends to the upper end of the fixed column 110, thus being open at the top, but does not extend to the lower end of the fixed column 110, thus being closed at the bottom. In other words, the lifting groove 111 is formed by starting from the lower end of the fixed column 110 at a certain distance upwards and extending vertically to the upper end.

[0074] The lifting groove 111 exposes the upper and lower lifting frames and the protrusion 121 of the lifting column 120 to the outside, and locks the lower protrusion 121 at the lower end of the lifting groove 111 to prevent the lifting column 120 from descending further.

[0075] The lifting column 120, which is inserted into the fixed column 110 and raised and lowered, is a structure for raising and lowering the roof 140, and the upper part of the lifting column 120 is connected to the roof 140.

[0076] As the lifting column 120 rises, the roof 140 also rises, thus forming an attic space above the main room 100. As the lifting column 120 descends, the roof 140 also descends.

[0077] An upper railing frame 126 and a lower railing frame 124 are provided on the outer surface of the lifting column 120 to form a railing for preventing falls from the upper space of the main room 100. Supports 127 are respectively provided on the upper and lower railing frames and are connected to upper and lower railing frames provided on adjacent other lifting columns 120. That is, the supports 127 are connected to adjacent upper and lower railing frames. Therefore, the supports 127 form a railing along the edge of the upper space of the main room 100 to prevent occupants from falling.

[0078] The bracket 127 is attached to the upper railing frame 126 and the lower railing frame 124 respectively, and is configured perpendicular to the upper railing frame 126 and the lower railing frame 124.

[0079] The upper railing frame 126 and the lower railing frame 124 move independently of each other. A central groove 125 communicating with the lifting groove 111 of the fixed post 110 is formed on one side of the lower railing frame 124. All sides of the upper railing frame 126 are closed, with no open portions. That is, the lower railing frame 124 has a spaced-out area to allow the upper lifting frame 123 to pass through.

[0080] When the rising column 120 is not raised inside the fixed column 110, the upper railing frame and the lower railing frame are in contact with each other. When the rising column 120 rises, the distance between the upper railing frame and the lower railing frame is increased, thereby forming a railing.

[0081] In the lifting column 120, an upper lifting frame 123 and a lower lifting frame 122, which contact the upper and lower railing frames and raise them, are formed through the lifting groove 111. The upper lifting frame 123 and the lower lifting frame 122 respectively raise and lower the upper railing frame 126 and the lower railing frame 124.

[0082] The upper lifting frame 123 protrudes through the lifting groove 111 of the fixed column 110 and is formed with a narrow width to allow passage through the central groove 125 of the lower railing frame 124. When the lifting column 120 rises, the upper lifting frame 123 contacts the upper railing frame 126 through the central groove 125 of the lower railing frame 124 and pushes the upper railing frame 126 upward. That is, the interior of the lower railing frame 124 separates, allowing the upper lifting frame 123 to pass through.

[0083] The lower lifting frame 122 is formed with a width greater than that of the central groove 125 of the lower railing frame 124, thereby contacting the lower railing frame 124. In one embodiment of the present invention, the lower lifting frame 122 is T-shaped, but the lower lifting frame 122 can be any shape that allows it to contact the lower railing frame 124.

[0084] The upper lifting frame and the lower lifting frame protrude through the lifting groove 111 and are spaced apart from each other. The distance between the upper and lower lifting frames becomes the distance between the upper and lower railing frames as the lifting column 120 rises. First, the upper lifting frame 123 contacts the upper railing frame 126 through the central groove 125 of the lower railing frame 124 and pushes the upper railing frame 126 upward. As the lifting column 120 continues to rise, the lower lifting frame 122 also contacts the lower railing frame 124 and pushes the lower railing frame 124 upward. Therefore, the distance between the upper and lower lifting frames is equal to the distance between the upper and lower railing frames.

[0085] A fall arrestor 112 is formed on the fixed column 110 to prevent accidents caused by the sudden drop of the roof 140, thereby protecting the safety of residents when the lifting column 120 rises to form the upper space.

[0086] The fall arrestor 112 can be formed at a certain height along the vertical direction of the fixed column 110. The fall arrestor 112 is a structure used to prevent the lifting column 120 from falling, and therefore it is located at the lower limit.

[0087] The fall arrestor 112 is formed at the lower part of the lifting column 120 and contacts the protrusion 121 that moves up and down along the lifting groove 111 to prevent the lifting column 120 from moving downward.

[0088] The fall arrestor 112 is formed to traverse the lifting groove 111 and is a structure that contacts the lower guardrail 124 or the protrusion 121 (described later) to prevent falls. When the fall arrestor 112 is open, the lower guardrail 124 or the protrusion 121 can freely rise and fall along the lifting groove 111. When the fall arrestor 112 is closed, the raised lower guardrail 124 or the protrusion 121 is locked and cannot descend further. Therefore, after raising the roof 140 to a certain height, closing the fall arrestor 112 allows camping to be enjoyed in the upper space created after the roof 140 is fixed at a certain height.

[0089] The lifting columns 120 can be raised and lowered inside the fixed columns 110 located at the four corners of the main chamber 100, and all lifting columns 120 must be raised and lowered to the same height simultaneously. Therefore, the lifting method of the lifting columns 120 can be set to hydraulic or manual.

[0090] When the lifting column 120 operates hydraulically, hydraulic pressure is generated by a hydraulic generator (not shown) located inside or outside the main chamber 100. The hydraulic pipe (not shown) connected to the hydraulic generator (not shown) branches and connects to the lower part of each lifting column 120, thereby raising and lowering the lifting column 120 by hydraulic pressure at the lower part of the lifting column.

[0091] Alternatively, to operate the lifting column 120 manually, a single rotating shaft 300 is provided on the upper part of the main chamber 100 according to an embodiment of the invention. The rotating shaft 300 is disposed on one side of the main chamber 100 and is horizontally arranged along its longitudinal length. The rotating shaft 300 can be connected to the fixed column 110 or the outer surface of the main chamber 100.

[0092] The rotating shaft 300 is a single structure used to simultaneously raise and lower all the lifting columns 120. A protrusion 121 is formed at the lower part of the lifting column 120 and is fixedly connected to the chain 330. By moving the chain 330 upward, the lifting column 120 is raised.

[0093] The protrusion 121 may form a groove to allow the chain to pass through, or it may be fixed by welding to the chain.

[0094] A sprocket is provided on the rotating shaft 300 to mesh with the chain 330. As the sprocket rotates, the chain 330 also moves, thereby causing the lifting column 120 to rise or fall. The sprocket consists of a first sprocket 310 and a second sprocket 320.

[0095] The sprockets each have two first sprockets 310 and two second sprockets 320, with the second sprockets 320 positioned outside the rotation shaft 300 relative to the first sprockets 310. As the rotation shaft 300 rotates, the first sprockets 310 and the second sprockets 320 rotate simultaneously on the same axis. Furthermore, the first sprockets 310 and the second sprockets 320 are formed with the same diameter.

[0096] The single rotating shaft 300 is arranged horizontally; therefore, there are two lifting columns 120 adjacent to the rotating shaft 300 and two lifting columns 120 not adjacent to the rotating shaft 300. For example, when the rotating shaft 300 is viewed from the front surface of the main chamber 100, if the rotating shaft 300 is arranged on the left side of the main chamber 100 along its longitudinal length, the lifting columns 120 located on the left front and rear are adjacent to the rotating shaft 300, and the lifting columns 120 located on the right front and rear are not adjacent to the rotating shaft 300.

[0097] The chain 330 connected to the protrusion 121 of the lifting column 120 adjacent to the rotating shaft 300 engages with the first sprocket 310, and the chain 330 connected to the protrusion 121 of the lifting column 120 not adjacent to the rotating shaft 300 engages with the second sprocket 320. Both chains have one end fixedly connected to the protrusion 121 and the other end housed within the chain box 340.

[0098] In the lifting column 120 adjacent to the rotating shaft 300, one end of the chain 330 is connected to the protrusion 121 of the lifting column 120 and engages with the first sprocket 310 of the rotating shaft 300, while the other end is housed in the chain box 340.

[0099] In the lifting column 120, which is not adjacent to the rotating shaft 300, one end of the chain 330 is connected to the protrusion 121 of the lifting column 120, and first engages with the upper idler wheel 115, and secondly engages with the second sprocket 320 of the rotating shaft 300, while the other end is housed in the chain box 340. The idler wheel 115 can be connected to a fixed column 110, which is not adjacent to the rotating shaft 300, or to the outer surface of the main chamber 100.

[0100] Therefore, when the rotating shaft 300 rotates, the chain 330 pulls the protrusion 121, causing all the lifting columns 120 to rise simultaneously. The chain 330 is loaded into the chain box 340 according to the length of the rise. When the rotating shaft 300 rotates in the opposite direction, the chain 330 loaded into the chain box 340 comes out of the chain box 340, causing all the lifting columns 120 to fall simultaneously. At this time, for all the lifting columns 120, the range of rise and fall of the lifting columns 120 according to the rotation of the rotating shaft 300 is the same.

[0101] Therefore, the chain 330 connects to the lifting column 120 adjacent to the rotating shaft 300 and to the lifting column 120 not adjacent to the rotating shaft 300, thus moving with the rotation of the single rotating shaft 300, causing the lifting columns 120 to rise and fall simultaneously. Since there is only one rotating shaft 300, and the chain 330 is also connected to the lifting column 120 not adjacent to the rotating shaft 300, moving in conjunction with the rotating shaft 300, all lifting columns 120 can be raised and lowered simultaneously. Therefore, the structure is simple and economical.

[0102] Bed frames 130 are folded on both sides of the main room 100. To ensure sufficient interior space in the main room 100, the bed frames 130 fold vertically, thereby improving space efficiency. The vertically folded bed frames 130 are housed within the wall, preventing interference with the secondary room 200. After the secondary room 200 is pulled out to the outside of the main room 100, the bed frames 130 are unfolded horizontally, thus creating a bedroom space within the main room 100. The unfolded bed frames 130 can be separated from the floor of the main room 100, and a separate support frame (not shown) can be used to support the load of the bed frames 130 between the floor of the main room 100 and the bed frames 130. Hinges (not shown) for folding can be connected to the lower part of the bed frames 130.

[0103] When the bed frame 130 is folded vertically, an outer wall 160 can be formed in the main chamber 100 to protect the bed frame 130. The outer wall 160 becomes the outer surface of the main chamber 100, and the bed frame 130 is disposed between the inner wall of the main chamber 100 and the outer wall 160.

[0104] like Figures 8 to 10 As shown, the auxiliary room 200, which is located inside the main room 100, is a structure for expanding the camping space of the camping room. It is inserted into the main room 100 and pulled out to the outside when in use.

[0105] The secondary chamber 200 is formed to be smaller than the main chamber 100 so as to be inserted into the interior space of the main chamber 100, and one side of the secondary chamber 200 is open and communicates with the interior space of the main chamber 100.

[0106] A chamber wheel 210 is provided at the lower part of the auxiliary chamber 200 to facilitate smooth insertion and withdrawal. The chamber wheel 210 can slide along the guide rail surfaces of the main support 500 and the auxiliary support 400 (described later), thereby being pulled out from or inserted into the main chamber 100.

[0107] The chamber wheel 210 is in the shape of a wheel, but is not limited thereto; it can be shaped like a guide rod that extends along the pull-out direction.

[0108] There is no height difference between the main support 500 and the auxiliary support 400, which will be described later, so the insertion or withdrawal of the chamber wheel 210 can be performed smoothly.

[0109] In addition, when the sub-support 400 is folded vertically as described later, the chamber wheel 210 can be locked in place by the sub-support 400 and cannot be pulled out.

[0110] An entrance / exit door 150 is provided on the front surface of the secondary chamber 200, allowing access to and from the secondary chamber 200. The entrance / exit door 150 is also provided on the rear surface of the main chamber 100. Therefore, the structure is ventilated by being opposite to the entrance / exit door 150 of the secondary chamber 200, which is beneficial for air exchange.

[0111] By opening the side of the secondary room 200, the sense of openness of the interior space can be improved. A window 221 can be formed at a certain height in the eaves 220.

[0112] When the eaves 220 are folded, they form one side of the secondary chamber 200. When the eaves 220 are lifted, they rise and rotate to form an eaves 220 that protrudes outward toward the secondary chamber 200, thus not only providing rain and snow protection but also enhancing the sense of openness.

[0113] The eaves 220 form the side wall of the sub-room 200 when folded, and form the eaves 220 extending from the ceiling of the sub-room 200 to the outside when unfolded.

[0114] An extended floor 230 is provided inside the eaves 220, forming a floor surface on the exterior of the secondary chamber 200. The extended floor 230 is located inside the secondary chamber 200, and when extended outwards, it unfolds and extends from the floor surface of the secondary chamber 200, thereby creating additional space. The eaves 220 is located above the extended floor 230 in its unfolded state, thus providing rain and snow protection.

[0115] The extended floor 230 is vertically arranged inside the sub-chamber 200, and floor wheels 231 are provided at the bottom to slide on the floor guide rail 240 of the sub-chamber 200.

[0116] The floor guide rail 240 of the sub-chamber 200 is arranged along the direction in which the extended floor 230 is unfolded. A stop 250 is formed at the outer end of the floor guide rail 240, which is formed at a height higher than the guide rail surface of the floor guide rail 240, thereby creating a height difference. The stop 250 is a structure for engaging and locking the locking table 232 of the floor guide rail 240.

[0117] The extended floor 230 moves outward along the floor guide rail 240 and rotates downward, so that the locking plate 232 formed on the floor wheel 231 engages and locks on the stop plate 250 to restrict rotation and prevent the extended floor 230 from falling out of the sub-chamber 200.

[0118] A folding panel 233 capable of extending the floor is provided on the extended floor 230. The folding panel 233 is connected to the extended floor 230 via a floor hinge 234. When the folding panel 233 is unfolded, it forms an additional floor surface.

[0119] As the extended floor 230 unfolds outward from the sub-chamber 200, the folding panel 233 also unfolds, thereby forming the spatial ground of the floor.

[0120] Furthermore, since the folding panel 233 forms the floor surface in an auxiliary manner, the size of the extended floor 230 can be reduced. The extended floor 230 and the folding panel 233 are configured such that, in the folded state, their height is lower than the height of the window 221 of the eaves 220. Therefore, the extended floor 230, located on the inner side of the eaves 220, does not obstruct the window 221 of the eaves 220, thus maintaining a sense of openness.

[0121] Furthermore, the floor surface of the secondary chamber 200 and the floor surface of the extension floor 230 are formed at the same height, so there is no height difference, which facilitates access from the secondary chamber 200 to the extension floor 230.

[0122] Observe the unfolding action of the eaves 220 and the extended floor 230. The extended floor 230 is set inside the eaves 220 in a manner that does not block the window 221. The eaves 220 is raised to form a ceiling, and the extended floor 230 is unfolded to the outside of the secondary room 200.

[0123] The floor wheels 231 of the extended floor 230 slide along the floor guide rail 240 and are pulled out to the outside. The extended floor 230 is rotated at the end of the floor guide rail 240 so that the extended floor 230 in the vertical direction is laid flat in the horizontal direction, thereby forming the floor surface.

[0124] At this time, the locking plate 232 formed on the floor wheel 231 engages and locks on the stop plate 250 at the end of the floor guide rail 240, thereby keeping the extended floor 230 in a horizontal position and preventing the sub-chamber 200 from detaching from the sub-chamber 200 to the outside.

[0125] The occupants of the camping space can enjoy camping in the additional space formed by the extended floor 230 and the eaves 220.

[0126] like Figures 11 to 13 As shown, the main chamber 100 and the auxiliary chamber 200 extend the camping space. The main chamber 100 is supported by a main support 500 located at the bottom, and the auxiliary chamber 200 is supported by a secondary support 400.

[0127] The fixed column 110 supporting the main chamber 100 is located on the outside of the main support 500 to support the load, and the main support 500 forms the floor surface of the main chamber 100.

[0128] The secondary support 400 is a frame used to support the secondary chamber 200, and is folded and connected to the main support 500.

[0129] The hinge frame 510 is attached to the outer side of the main support 500, and the rotating hinge 410 of the secondary support 400 is connected to the hinge frame 510. Since the hinge frame 510 is located on the outside of the main support 500, the rotating hinge 410 of the secondary support 400 can be located on the same plane as the main support 500, and the guide rail surfaces of the main support 500 and the secondary support 400 are also formed at the same height, thus eliminating any height difference. The guide rail surfaces of the main support 500 and the secondary support 400 also form the same plane.

[0130] In addition, the rotating hinge 410 is formed in an arc shape, so that the rotating hinge 410 will not come into contact with the main support 500 when rotating, thus the movement of the rotating hinge 410 is smooth.

[0131] The sub-support 400 can be folded vertically or horizontally via the rotating hinge 410. When moving the camping house of the present invention to the campsite, the sub-support 400 is folded to minimize its volume. When installing it at the campsite, the sub-support 400 is rotated downwards and placed horizontally, and then the sub-chamber 200 is pulled out from inside the main chamber 100 and placed on the sub-support 400.

[0132] To increase the length of the sub-support 400, an extension support 420 connected to the sub-support 400 by an extension hinge 421 is provided. The extension hinge 421 is provided on the extension support 420 so that the extension support 420 can be folded at the end of the sub-support 400, and the extension support 420 can be folded in a vertical or horizontal direction.

[0133] When the length of the secondary support 400 supporting the secondary compartment 200 is short, the extension support 420 is extended to increase its length. In this way, the secondary support 400 can be formed to a sufficient length to support the secondary compartment 200. When the campsite is moved, the secondary support 400 is folded vertically; therefore, if it is higher than the height of the main compartment 100, it will cause inconvenience during movement.

[0134] Therefore, the extension bracket 420 is foldably connected to the sub-bracket 400, thereby enabling the sub-bracket 400 to be formed at a height lower than the main chamber 100. When the length used to support the sub-chamber 200 is insufficient, the extension bracket 420 can be unfolded to increase its length.

[0135] Furthermore, an extension chamber (not shown) can be provided, forming a camping space within the interior and capable of being pulled further out from the interior of the secondary chamber 200. This allows the camping house of the present invention to be configured as a three-section or more structure. The extension support 420 can be provided to support the further extended chamber (not shown). In this case, the interior space of the camping house is further expanded, allowing for a more relaxed and spacious camping experience. By providing the extension support 420, the camping house of the present invention can be configured as a multi-section camping house with three or more sections.

[0136] The extension bracket 420 has a fixing protrusion 422 that protrudes outward. When the extension bracket 420 is folded vertically, the fixing protrusion 422 is formed on the upper part of the extension bracket 420 and protrudes to both sides.

[0137] The fixing protrusion 422 is a structure used to fix the extension bracket 420 and the sub-bracket 400 in a vertically folded state, and it is inserted into the bracket fixing groove 113 formed in the fixing bracket 110.

[0138] The fixing protrusion 422 is inserted between the bracket fixing grooves 113, and in order to prevent the fixing protrusion 422 from falling out of the bracket fixing grooves 113, a fixing member 114, such as a bolt, passes through the bracket fixing grooves 113. Through the fixing member 114, the fixing protrusion 422 will not detach from the bracket fixing grooves 113.

[0139] The fixing protrusion 422 is disposed on the extension bracket 420. In order for the fixing protrusion 422 to be inserted into the bracket fixing groove 113, the extension bracket 420 and the sub-bracket 400 must be in a folded state. Therefore, the sub-bracket 400 and the extension bracket 420 are fixed in a vertically folded state by the fixing protrusion 422. The sub-bracket 400 is also in a folded state by the fixing protrusion 422 formed on the extension bracket 420.

[0140] The following example illustrates the operation of the multi-section camping house according to the present invention.

[0141] In the camping cabin of the present invention, the vehicle loading compartment is mounted on a mobile frame such as a trailer, thereby moving to the campsite. When moving to the campsite, the sub-support 400 and the extension support 420 are in a folded state, and the fixing protrusion 422 is inserted into the support fixing groove 113 and fixed in the folded state.

[0142] In addition, the secondary support 400 is formed with a length that is less than the height of the main chamber 100, thus reducing the risk of collision with obstacles during movement.

[0143] When installing the camping house of the present invention after arriving at the campsite, the fixing member 114 of the bracket fixing groove 113 is released, and the sub-bracket 400 and the extension bracket 420 are unfolded in the horizontal direction.

[0144] Then, the secondary chamber 200 is pulled out from inside the main chamber 100 and placed on the guide rail surface of the secondary support 400. When an extension chamber (not shown) is further provided inside the secondary chamber 200, the extension chamber (not shown) is pulled out. At this time, there is no height difference between the main support 500 and the secondary support 400, so the secondary chamber 200 can be pulled out smoothly.

[0145] The main support 500, the secondary support 400, and the extension support 420 support the main chamber 100 and the secondary chamber 200 at the bottom.

[0146] Campers can access the interior camping space through entrances 150 located in the main room 100 and the secondary room 200, and can ventilate after all entrances 150 are opened.

[0147] Additionally, in the main chamber 100, the lifting column 120 inside the fixed column 110 raises the roof 140, thereby separating the space through the layer wall 141 to form an upper attic space. The lifting column 120 can be raised and lowered synchronously by hydraulic pressure. When raised and lowered manually, when a single rotating shaft 300 located on one side of the main chamber 100 is rotated, the chain 330 engaging with the first sprocket 310 or the second sprocket 320 raises the protrusion 121 of the lifting column 120, causing the lifting column 120 to rise.

[0148] By rotating a single rotating shaft 300, all the lifting columns 120 connected by the chain 330 can be raised and lowered simultaneously.

[0149] As the lifting column 120 rises, the upper and lower lifting frames also rise together. The upper lifting frame 123 pushes the upper railing frame 126 upward after passing through the central groove 125 of the lower railing frame 124. Then, the lower lifting frame 122 also causes the lower railing frame 124 to rise. As the distance between the upper and lower lifting frames is increased, a railing is formed in the space above the floor wall 141, thereby preventing residents from falling.

[0150] Furthermore, after the lifting column 120 rises, the anti-fall frame 112 of the locking fixed column 110 is engaged and locked to prevent the lifting column 120 from falling further, thus preventing safety accidents.

[0151] In the secondary chamber 200, the eaves 220 forming the side walls form an additional ceiling by rising and rotating, and the extended floor 230 located inside the eaves 220 also rotates downward to extend the floor surface.

[0152] The extended floor 230 rotates as it moves along the floor guide rail 240. When the locking platform 232 of the floor wheel 231 engages and locks onto the fixing frame, the extended floor 230 is fixed in the horizontal direction.

[0153] Because the extended floor 230 and the eaves 220 form an additional space that connects to the outside, campers can feel a sense of openness.
