Description

Technical Field

[0001] This invention relates to a yurt structure, and more particularly to a yurt device with an integral collapsible mesh frame structure. Background Technology

[0002] The main structure of a traditional yurt is a timber frame, consisting of three parts: the roof (skylight), the rafters, and the walls. The traditional yurt's walls are a double-layered, folded wooden frame, hinged at a single point with leather ropes. The roof is a circular wooden frame with small holes for securing the rafters. Each section of the wall, the rafters to the walls, and the walls to the door are connected using specific binding methods with horsehair ropes. The yurt is assembled from the inside out. First, the walls are erected, and one person holds the roof in the center. The others insert one end of the rafter into the roof and connect the other end to the walls around the center. Once all components are connected, sandbags are suspended from the roof to aid in center positioning. Ropes are then used to bind the walls from the outside to prevent them from unfolding further. Finally, layers of felt are wrapped in a specific order. After the felt is completely covered, the sandbags can be removed, and the yurt now forms a stable structural system.

[0003] The ease of transporting and rapid assembly / disassembly of yurts stems from their scissor-like deployable structure, known as the "khana," which allows for opening and closing. Scissor-like deployable structures are a general term for spatial structures based on scissor-like structural units. The deformable nature of these units grants them the ability to expand and contract. A basic scissor unit consists of two hinged rods. Based on the location of the hinge point and the geometry of the rods, they can be categorized into three types: translational units, polar units, and angulated units. In translational units, the two rods are straight rods of equal length, with the hinge point at the midpoint. In polar units, the two rods are straight rods, with the hinge point offset from the midpoint. In angulated units, both rods are broken segments, with the hinge point at the bend. All three types of scissor units possess one degree of freedom in one direction, giving them variable characteristics. Under specific conditions, multiple scissor units can be hinged together while still maintaining their variable properties. However, these unit combinations retain degrees of freedom even after full deployment, and only by applying other external constraints can the mechanism be transformed into a stable structure. Therefore, ensuring the overall deployability and foldability while maintaining stability in its deployed state is the core problem that needs to be solved when applying scissor-type deployable structures.

[0004] In traditional yurts, to ensure the stability of the scissor-type deployable yurt sidewall frame—the khana—each individual member of the frame is bent, resulting in a cylindrical sidewall after unfolding. This is achieved through the interaction of the members, creating a slight locking mechanism. Furthermore, the outer side of the overall enclosed frame must be restrained by inner ropes to prevent further outward unfolding. However, traditional yurts use leather or horsehair ropes as connection materials, which are no longer suitable for modern industrial mass production. Additionally, the method of fixing nodes by binding lacks stability, requires high skill in assembly, is difficult to operate, and often requires several experienced locals to complete. In short, the traditional double-layered, cross-folding wooden frame of the yurt requires multiple khana pieces to be bound and assembled on-site. Even after the khana is erected and bears weight, it still needs the restraint of ropes to achieve stability in all directions of the deployable structure. The installation process is technically challenging and inefficient. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a yurt device with an integrated structure, stable stress distribution, efficient assembly, and reasonable space utilization, featuring an overall collapsible grid frame structure.

[0006] Technical Solution: This invention proposes a yurt device with an integrated collapsible mesh frame structure, including a roof frame, a wall frame, and an outer felt enclosure. The wall frame comprises four mesh surfaces, forming a single-layer mesh frame structure with four integrated surfaces. The roof frame includes a skylight and rafters. The skylight and the wall frame have square cross-sections. The skylight is located directly above one corner of the wall frame and is directly connected to two adjacent mesh surfaces. It is connected to the other two mesh surfaces of the wall frame via rafters. The mesh surfaces of the wall frame are connected by a corner folding mechanism. Each mesh surface includes several parallel long support rods, which are hinged on both sides by a planar folding mechanism. There are several short support rods, and two adjacent long support rods are connected by short support rods. Each pair of short support rods is connected to the long support rod sandwiched between them by Z-shaped members and bolts, forming a scissor-type deployable structural unit with self-locking capability. The long support rod and the two short support rods connected by the Z-shaped members can rotate relative to each other. When the short support rod rotates to be perpendicular to the long support rod, the end of the short support rod abuts against the middle of the long support rod. The short support rod is unidirectionally positioned by the long support rod and the planar folding mechanism, so that the scissor-type structural unit can remain stable under the action of gravity and vertical pressure when it is unfolded. The unit is arranged to form a two-dimensional scissor-type structural mesh, which becomes a relatively stable structure that can bear load in one direction when unfolded.

[0007] Preferably, the four mesh surfaces of the fence frame include two first mesh surfaces directly connected to the skylight and two rectangular second mesh surfaces. The first mesh surface is a pentagonal structure with three right angles, one side of which is the same length as the side of the skylight, and another side is the same length as the height of the second mesh surface. The side between these two sides is a hypotenuse, and rafters are installed thereon.

[0008] Preferably, the planar folding structure is a Z-shaped component, the center of which is hinged to the long support rod, and both ends are fixedly connected to the two short support rods respectively; the long support rod and the short support rods rotate relative to each other in the same plane, and the maximum rotation is that they are perpendicular to each other; several Z-shaped components are evenly distributed on the long support rod, and the long support rod and the short support rods are connected to form a network through the Z-shaped components.

[0009] Preferably, the long support rods at the edges of each mesh surface of the fence frame are equipped with several supplementary short support rods of non-fixed length through Z-shaped or L-shaped components, forming a sufficient number of hinge points at the edges of the mesh surface to facilitate stable connection between mesh surfaces or between the mesh surface and the skylight.

[0010] Preferably, the corner folding mechanism is a first U-shaped component, the bottom surface of which is fixed to the end of a long or short support rod of a mesh surface by a screw, and the two sides are rotatably connected to the ends of the corresponding long or short support rods of adjacent mesh surfaces.

[0011] Preferably, the skylight is connected to the long or short support rod of the first mesh surface via a second U-shaped component. The second U-shaped component is fixedly installed on the frame of the skylight, and the end of the long or short support rod is rotatably connected to the second U-shaped component.

[0012] Preferably, the skylight and the rafters are connected by a third U-shaped component, which is fixedly installed on the frame of the skylight, and the ends of the rafters are rotatably connected to the third U-shaped component.

[0013] Preferably, the rafter is connected to the planar folding mechanism at the top of the second mesh surface via a hanging clip structure; the hanging clip structure is U-shaped, fixedly installed on both sides with the ends of the rafter, and has a snap-fit ​​hole at the bottom; the corresponding planar folding structure has a snap-fit ​​post at its center that mates with the snap-fit ​​hole.

[0014] Preferably, the bottom of the connection between the two second mesh surfaces is provided with an opening, and the long support rod at the opening is connected to the short support rod by an L-shaped component.

[0015] Working Principle: The fence frame is a foldable space frame structure that can be unfolded and folded using a folding mechanism. It is a four-sided scissor-type deployable planar space frame, with each side consisting of several self-locking scissor-type deployable nodes. After unfolding, under its own weight and the downward pressure from the roof frame, each side of the frame unfolds synchronously via corner members. The entire frame achieves self-stability when the long and short members are vertical. Furthermore, within the stress range of the selected materials, the greater the vertical pressure applied to the frame, the better its stability. When a certain upward vertical force is applied to the unfolded frame, the short members rotate back from their locked positions, thus folding down a single side of the frame. Through the corner members, all four sides of the frame fold down synchronously, achieving the overall folding down of the entire frame. The roof frame can be stored as a whole, and the roof frame and the wall frame are connected by hinged or hooked metal components, making disassembly convenient. This invention utilizes a structure that is easy to install and store to assemble a yurt frame, and wraps the outside of the frame with felt to form a complete yurt device with extreme climate coping performance.

[0016] Beneficial Effects: Compared with the prior art, this invention has the following advantages: 1. The folding principle and support rod movement speed of each side of the single-layer collapsible space frame structure wall are corresponding and synchronous. By using components to connect the corresponding two ends to form multi-directional hinge nodes, the four-sided space frame is connected into a whole through the hinge nodes, which can achieve good compression resistance and mutual support effect; 2. Using single-layer wooden space frame mutual support hinge nodes, during the folding process, both short and long supports move. The short supports gradually approach each other with the long supports connected on both sides as the axis, and drive all long supports to fold synchronously, finally folding into a tightly arranged single-layer rod bundle. When unfolded, the angle between the short and long supports gradually increases until they are perpendicular to each other. Unidirectional movement is restricted to form a stable space frame structure. The Z-shaped metal components realize the effective resistance to lateral thrust through the hinge. This allows for single-quadrant variable components, which on the one hand enhances the structural strength of the nodes, making the overall structure more stable, and on the other hand reduces the amount of wooden rods used; 3. By connecting the space frame with metal prefabricated components in the form of hinged nodes, the wall frame and roof frame can be efficiently pre-assembled using tools, and stored and transported after being folded up. On-site deployment enables rapid assembly, replacing the traditional Mongolian yurt construction process where many people manually bind and assemble the structure, effectively saving time. The entire wooden space frame structure can be assembled within 10-20 minutes; 4. The skylights are arranged in a square eccentric pattern, providing basic lighting and ventilation while also allowing the stove to be placed in one corner, which is conducive to the intensive use of indoor space. At the same time, the rectangular plane replaces the traditional circular shape of the Mongolian yurt, which is more conducive to the placement of modern furniture compared to the traditional Mongolian yurt.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 1-16As shown, a yurt device with an overall collapsible mesh frame structure includes a skylight 11, a wall frame 2, and an outer felt. The skylight 11 and the wall frame 2 have square cross-sections, with the skylight 11 located directly above one corner of the wall frame 2. The wall frame 2 includes two first mesh surfaces 21 directly connected to the skylight 11 and two rectangular second mesh surfaces 22. The first mesh surface 21 is a pentagonal structure with three right angles, one side of which is the same length as the side of the skylight 11, and another side is the same length as the height of the second mesh surface 22. The side between these two sides is a hypotenuse. The skylight 11 and the second mesh surfaces 22 of the wall frame 2 are connected by several rafters 12. The skylight 11 and the rafters 12 form the roof frame 1. Both the skylight 11 and the rafters 12 are made of wood.

[0035] The fence frame 2 consists of support rods and connectors.

[0036] Each mesh panel of the fence frame 2 includes several long support rods 201 and short support rods 202 hinged together by Z-shaped members 3. The center of the Z-shaped member 3 is hinged to the long support rod 201, and two short support rods 202 are fixedly connected to each end. Several Z-shaped members 3 are hinged to the same long support rod 201, and several short support rods 202 are connected to both sides. The two ends of the same short support rod 202 are fixedly connected to the Z-shaped members 3 on two adjacent long support rods 201. The long support rods 201 and short support rods 202 are connected by Z-shaped members 3 to form the mesh plane. The long support rods 201 are parallel to each other and evenly distributed, arranged at an angle on the mesh surface, and are of unequal length. The short support rods 202 are parallel to each other, and the short support rods 202 between adjacent long support rods 201 are evenly distributed and of equal length. When the mesh panel is unfolded to a stable state, the long support rods 201 and short support rods 202 are perpendicular, and the structure is locked in one direction.

[0037] The long support rods 201 at the edges of each mesh surface of the fence frame 2 are equipped with several supplementary support rods of non-fixed length through Z-shaped components 3 or L-shaped components 7, forming a sufficient number of hinge points at the edges of the mesh surface to facilitate stable connection between mesh surfaces or between the mesh surface and the skylight.

[0038] An opening is provided at the bottom of the connection between the two second mesh surfaces 22 of the fence frame 2, and a short support rod 202 is connected to one side of the long support rod 201 at the opening through an L-shaped component 7.

[0039] The support rods include long support rod 201, short support rod 202 and supplementary support rods, all of which are made of wood.

[0040] The mesh panels are connected by a first U-shaped component 4, and the fence frame 2 can be folded up as a whole. The bottom surface of the first U-shaped component 4 is fixed to the end of a support rod of one mesh panel by a screw, and the two sides are rotatably connected to the corresponding support rod ends of adjacent mesh panels.

[0041] The skylight 11 is connected to the first mesh panel 21 via a second U-shaped component 5. The bottom of the second U-shaped component 5 is fixedly installed on the frame of the skylight 11. The ends of the support rods of the first mesh panel 21 are rotatably connected to both sides of the second U-shaped component 5. The second U-shaped component 5 has the same structure as the first U-shaped component 4. The skylight 11 is connected to the rafters 12 via a third U-shaped component 6. The bottom of the third U-shaped component 6 is fixedly installed on the frame of the skylight 11. The ends of the rafters 12 are rotatably connected to the bent sides of the third U-shaped component 6. The rafters 12 are connected to the Z-shaped component 3 at the top of the second mesh panel 22 via a hanging structure 8. The hanging structure 8 is U-shaped, with both sides fixedly installed to the ends of the rafters 12, and a snap-fit ​​hole 81 at the bottom. The corresponding Z-shaped component 3 has a snap-fit ​​post 82 at its center that mates with the snap-fit ​​hole 81.

[0042] The connectors include Z-shaped component 3, L-shaped component 7, first U-shaped component 4, second U-shaped component 5 and third U-shaped component 6, all of which are metal components.

[0043] In this invention, during storage, the rafters 12 are removed from the second mesh surface 22, and the skylight 11 is removed from the wall frame 2. Then, the entire wall frame 2 is folded up. During the folding process, both the short support rods 202 and the long support rods 201 move. The short support rods 202 gradually move closer together with the long support rods 201 connected to them on both sides as axes, and all the long support rods 201 are folded up synchronously, finally folding into a tightly arranged single-layer bundle of rods. At the same time, the roof assembly 1 is stored up. In specific use, the wall frame 2 is erected and unfolded, which can be completed within 18-26 seconds. Then, the skylight 11 and the rafters 12 are connected to the wall frame 2 using connectors, thus realizing the construction of the yurt frame. The entire process can be completed within 10-20 minutes. Finally, felt is covered on the outside of the frame. For environmental protection, the felt can be recycled from old felt, clothing, etc.
