[0002] E04H 1 / 00 - E04B 1 / 343 - E04H 1 / 12

[0003] In portable temporary structures with easy opening and closing mechanisms, several patents have been registered, each of which helps to improve the efficiency and ease of use of these structures in some way. We will examine these patents below:

[0004] Emergency shelter with modular opening and closing structure: This patent, registered number 102378 by Ghazaleh Abbasian, provides an emergency shelter with a modular structure that can open and close quickly. This feature allows for practical use in emergencies.

[0005] The difference between this invention and the temporary structure presented: In addition to emergency accommodation, our structure is designed for other applications, such as temporary markets and workshops. Its opening and closing mechanisms are less complex and require less manpower. Our structure also emphasizes optimization in transportation and warehousing, which is less considered in this patent.

[0006] Folding Scissor-Like Structures: These structures use scissor-like mechanisms to allow for quick and efficient opening and closing. They are widely used in the design of temporary shelters and portable structures.

[0007] The difference between this invention and the proposed temporary structure is that the scissor-like mechanism usually requires more open space for operation and may increase the weight and complexity of the structure. Also, maintenance of these structures will be complicated and costly to maintain the scissors' efficiency. In contrast, our structure is designed without such limitations and provides simpler and safer use by eliminating rotational movements in the vertical direction of the structure. Also, our structure can carry a more significant number of structures in a vehicle, which reduces the cost and time of transportation.

[0008] Modular Portable Configuration for Holding Panels - Patent No. US8464493B2

[0009] The US8464493B2 patent focuses more on protecting against external threats, while our structure is designed to create temporary structures in emergencies. The two patents differ significantly regarding their purposes, applications, and technical features.

[0010] Prestressed Enclosure Construction System, Tool-Free, Polyhedral Structure - Patent No. US20080066393A1

[0011] The US20080066393A1 patent is designed more for constructing various types of complex structures using specific connection systems. In contrast, our structure focuses more on simple, portable temporary structures for immediate use, such as emergency shelters and temporary spaces. Therefore, the two patents differ in terms of their applications and features.

[0012] Deployable Portable Shelter - Patent No. US9410312B2

[0013] Both patents refer to portable temporary structures but with differences in design details. Patent US9410312B2 emphasizes the construction of quadrilateral and rectangular shelters with articulated joints and the use of a lever arm for deployment, while our structure focuses more on ease of installation and opening and closing without the need for tools or skilled labor. Our structure is faster to install, open, and close and is more optimal for emergency and temporary spaces.

[0014] Frame and roof system for portable shelter - Patent No. US10184264B2

[0015] Both patents relate to portable structures designed for quick and easy deployment. Patent US10184264B2 focuses more on the frame and roof structure for temporary shelters without tools. In contrast, our structure focuses on temporary and modular structures that can easily adjust for emergency and portable spaces. Our structure generally focuses more on the ease and speed of installation and opening and closing. In contrast, patent US10184264B2 focuses more on the frame structure and the connection of various members.

[0016] The present invention is a portable temporary structure designed with an easy and optimal opening and closing mechanism. It is suitable for multipurpose applications such as temporary housing, military camps, emergency housing, nature tourism camps, etc. The main problem with existing structures is that they require heavy equipment such as cranes and specialized personnel for installation, opening, and closing, as well as the high cost and time of transporting and storing these structures. The purpose of this invention is to provide a structure that, using a hinge mechanism and optimal design, allows opening and closing with minimal human effort and without the need for special tools. This structure is designed so several units can be transported and stored optimally. In the following steps, by removing the wall covering, it is possible to create a larger space by placing a number of these cells side by side, creating semi-open spaces for different uses by changing the material of the walls and also establishing cells specific to utility spaces by considering space for water tanks.

[0017] Temporary structures available for various applications, including emergency shelters, construction sites, temporary markets, and educational and recreational spaces, face numerous challenges. One of the main problems is the need for specialized personnel and heavy equipment, such as cranes, to open and close these structures, which increases costs and slows down the speed of operation. Also, many of these structures have vertical rotational movements when opened and closed, complicating the work process and requiring more user strength. In addition, common temporary structures take up a lot of space when folded, and only a limited number of them can be transported in a vehicle. This leads to increased costs and time for transportation and storage. The slow speed of setting up many of these structures in emergencies and the limitations of storage and transportation are among their most important weaknesses.

[0018] The main goal of this invention is to provide a solution to overcome the challenges raised and achieve an innovative temporary structure that is highly adaptable to different needs. This invention is designed so that it can be opened and closed without needing specialized personnel and heavy equipment. In addition, by eliminating the rotational movements in the vertical direction during opening and closing, using it becomes simpler and faster, reducing the need for physical force to bear the structure's weight. The structure of this cell is such that when closed, it occupies little space, and it is possible to carry up to 8 of them in a trailer, which leads to savings in transportation costs and time. With its flexible design, this invention covers a variety of applications, including emergency accommodation, temporary markets, construction sites, and educational and recreational spaces. It effectively addresses the weaknesses of previous temporary structures.

[0019] The geometry of opening and closing this cell is entirely different from previous similar examples, and the user can open or close the cell without needing a crane and expert force. Also, unlike previous examples, none of the parts have any rotation or movement in the vertical direction when opening and closing, so the user does not need to bear the weight force to open and close the structure, and the opening and closing process can be done with the help of two or even one person.

[0020] Also, when closed, this cell occupies a small area and volume, so eight can be mounted on conventional trailers.

[0021] • Low speed of erecting a large number of temporary structures in emergencies

[0022] • Occupying an ample space when storing these structures.

[0023] • Waste of cost and time of previous structures during relocation and transportation to the site (given that 8 of these cells can be loaded onto a trailer at once)

[0024] The main goal of this project is to achieve a final design that is most compatible with the desired goals and needs, such as emergency housing, construction sites, temporary markets, and educational and recreational spaces. The structure's flexibility and adaptability to different conditions, including expanding and contracting components and elements, are significant. It must also overcome the weaknesses of previous examples.

[0025] First, we see how the space cell opens and closes in the form of a diagram in. Finally, according to the diagram provided and the design of all details, the final space cell will be.

[0026] Design of additional modules

[0027] To expand the diversity of the spatial cell and the ability to increase the variety of uses, new ideas were proposed for the following designs of this project:

[0028] • Modules with facilities: The dimensions of this module are designed in such a way that 2 of them can be mounted on a trailer along with 8 of the main modules due to the proportions (the length of the frame when closed is half, and its width is twice the width of the main module), and the internal space provided allows us to install facilities and water and sewage tanks can be placed inside the frame. ()

[0029] • Middle modules: Besides the fact that all openings can be moved on the walls according to the user's needs, we considered new modules with the possibility of removing walls that can be used as a link between several modules to benefit from a more extensive and collective space. ()

[0030] • Glass wall and accordion wall modules: Finally, modules with opening walls were designed to provide cells with diverse spatial qualities and create a semi-open space to increase collective uses. (Figures 9 and 10)

[0031] Completing the final model:

[0032] Now, we will examine the structural structure of the multifunctional and modular open and closed space cell step by step. ()

[0033] • Frame

[0034] • Large wall

[0035] Mechanism: 360-degree wheel (to make it easier for the user to open the wall to help support the weight of the wall)

[0036] Large wall to small wall lock (to fix the two walls to each other and prevent the walls from moving during use)

[0037] • Small wall

[0038] Mechanism: Spring latch (to fill the offset joint created between the small wall panels during use)

[0039] The cause of the joint: to prevent friction between the small wall and the panels when rotating and opening, and closing

[0040] • Ceiling and floor panels

[0041] • Hinges and seals

[0042] • Furniture

[0043] Next, we will examine the type of all panels and walls in detail and connections in full. (Note that in the diagrams showing the components under consideration, due to the symmetry of the walls and panels, the symmetrical sections concerning the axis of symmetry have been removed.)

[0044] Material selection

[0045] According to the presented design, the thickness of the walls and panels and, as a result, the thickness of the selected material layering directly affect the final dimensions of the structure in the closed state. Therefore, we chose the material used so that, while being thin, we could have the most significant resistance among other materials available on the market. In total, we have used two basic materials in the design:

[0046] 1. Iron sheet

[0047] • 2.5 mm iron sheet for the design and manufacture of the main structural profiles

[0048] • 1.5 mm iron sheet for the design and manufacture of the secondary structural profiles

[0049] • 2 mm iron sheet for the manufacture of floor panels, columns, and connection corners

[0050] • 6 mm iron sheet for the manufacture of column hinge plates

[0051] 2. Aluminum-coated composite sheet

[0052] • 3 mm aluminum-coated composite sheet as a floor covering

[0053] • 5 mm aluminum-coated composite sheet as a covering for other parts

[0054] It should be said that for the grid structure of the frame and walls, instead of using the conventional galvanized LSF structure, we used to cut iron sheets with thicknesses of 1.5 and 2.5 mm so that we could avoid cutting at the installation site due to the high resistance of iron Hinges. Also, for the main profiles of the large wall, we need a dedicated cut to increase the cross-section width at the hinge installation location.

[0055] Frame

[0056] Based on the studies and samples examined, all opening and closing structures depend on a fixed core that, unlike other moving elements of the structure, does not change during the opening and closing process. When the structure is closed, it includes all components and furniture (if any).

[0057] Our central core is a frame on both sides of the designed sample. The walls and panels are symmetrically placed and rotated 180 degrees and, according to the design process diagrams, are opened and closed from both sides inside the frame. The designed frame consists of three parts: roof, floor, and columns, and in fact, all the components are ultimately hinged to these parts, so its structure must be much more potent and can withstand any twisting and shearing at the connection points to the hinges. The frame consists of multiple layers, with specific grid dimensions and defined profile thickness (figures 11-14).

[0058] Large wall

[0059] The next member is the large wall of the structure, which is the last layer in the layering of walls and panels. It relies less on the frame structure than other elements and is placed in a grooved form with the help of vertical connections to the frame column in the open position. We have the highest shear stress on the hinges of the enormous wall. So for the user's convenience when opening the wall, we place a wheel in the grooved corner that can rotate 360 ​​degrees and opens as soon as the wall is removed from the frame and easily allows us to open it without the need for several specialized forces with the ability to bear the weight of the wall. You can see the diagram of the designed wheel in the ().

[0060] The next main challenge raised in the design process section for the large wall was the rotation and displacement on the hinge axis. This was solved by optimizing the frame's geometry and designing a suitable hinge, which we will discuss later.

[0061] Figure (15) Exploded diagrams of two types of large walls (on one of the large walls, we included an opening for a window.) and Figure (16) Figure (17) Figure (18) Figure (19) show the location of other details installed on these walls, the dimensions of the grid and the thickness of the profiles used. In Figure (21), we also have the diagram of the designed lock, which is installed to fix and strengthen the small wall relative to the large wall and locks the two walls together after the small fence is wholly opened, which is the final stage.

[0062] Small Wall

[0063] The last member to open and in the layering, when closed, is placed on the axis closest to the axis of symmetry, is the small wall, and for this reason, when opened, all edges of the wall, except for the edge hinged to the frame column, are subject to friction with the large wall and the ceiling and floor panels. To solve this problem, the edges of the wall should be offset inward by the amount needed to create a seam so that the opening and closing operations can be carried out efficiently without additional force to pull the wall and without damaging the composite coverings. At the same time, the seals should be designed in such a way that after the opening of the structure is completed, all the edges created can be resealed. We solved this challenge in two ways: designing a type of all-round spring latch for sealing between the small wall and the panels and developing a kind of hinge with a sliding core for sealing between the small fence and the large wall.

[0064] Figure (22) Exploded diagrams of two types of small walls (on one of the large walls, we included an opening for a door.) and Figure (23) Figure (24) Figure (25) Figure (26) shows the location of other details installed on these walls, the dimensions of the grid and the thickness of the profiles used. It should also be noted that all openings, whether on a large or small wall, can be customized and moved to the desired walls.

[0065] Spring Latch

[0066] Details of the overall spring latch in order of formation:

[0067] 1. Design of a conventional spring latch mechanism that closes and opens with a click (the click causes the handle to rotate in a defined direction, resulting in the opening being closed and opened.) ()

[0068] 2. Creation of interconnected pairs of designed latch mechanisms. ()

[0069] 3. Place six pairs of latches together, connect them with a cover and sealant, and insert two handle slots in the formed row of latches (one row is placed on the top edge and one row on the bottom edge of the wall.) ()

[0070] Now, with this created mechanism, we fill the offset of the top and bottom edges of the wall after opening it by pressing both hands on the handles (one click), once at the bottom and once at the top.

[0071] It should be noted that the height difference of the latch in the closed and open state is precisely 3 cm; this is because the offset of the wall from the top and bottom edges must also be 3 cm. ()

[0072] Roof Panels

[0073] When opening the large wall, the interior and exterior roof and floor panels are then opened together. The main challenge in designing these panels, especially the roof panels, is their sealing. We will see that we created special sealants for these panels and an external roof seam cover. (It should be noted that the inner panel refers to the panel close to the frame, and the outer panel refers to the panel close to the large wall.)

[0074] Floor Panels

[0075] In the final stage, we reach the floor panels, which bear more force (including weight force) than the other parts. Therefore, to overcome this challenge and strengthen the structure of the floor panels, we make the grid of the panel profiles denser than the ceiling panels, and in addition, we consider a 2 mm layer of iron sheet for the final composite underlay.

[0076] Corner Connections

[0077] All structural profile connections are generally made in two ways:

[0078] 1. Connection between two profiles with the same height sections: cutting the engaged edges and connecting with a corner

[0079] 2. Connection between two profiles with different sections: the end of the profile with a smaller section is closed and directly bolted into the more prominent profile.

[0080] Therefore, because the profiles intersect at different and unequal angles, we designed corners specific to each point, cut them from 2 mm sheet iron, and bent them at the appropriate angle. Examples of the corners used are shown in Figure (36)

[0081] Hinge and seal between the large wall and the outer roof panel

[0082] Considering the way, the wall and panel rotate relative to each other, extruded rail and hinge seals were designed to match the angle and axis of rotation—similar to hinges available on the market—as shown inand, which illustrate the cross-section, exact dimensions, and 3D view of the hinge.

[0083] Hinge and Sealant Between the Large Wall and the Exterior Floor Panel

[0084] The next joint examined is the joint between the same wall and the exterior floor panel. Its hinge is the same as the previous hinge in terms of rotation, except that we made this hinge and all the hinges related to the floor thicker for greater strength. The seal is also the same as before.

[0085] Hinge and Sealant Between the Interior and Exterior Ceiling Panels

[0086] A simple hinge with dimensions specific to its location was designed, but as mentioned earlier, we had a sealing problem. We used an extruded toothed sealant between the two panels. However, the new joints created by the hinge placement still needed a final coating, so we finally fixed a rubber coating on all the hinges with a latch so that the opening and closing process of the panels would not be disrupted.

[0087] Hinge and Sealant Between the Inner and Outer Floor Panels

[0088] The next hinge and seal are again the same as the previous one, except that this hinge is thicker, and we no longer need a cover to protect the newly created seams.

[0089] Hinge and Sealant Between the Interior Panel of the Ceiling and the Frame

[0090] The next joint is the joint between the ceiling panel and the frame, and these joints created with the frame are very different from the others; the frame and the panel overlap, so we do not need a sealant on both members. The sealant is designed as an angled tooth that is compressed and sealed when the structure is opened.

[0091] Hinge and Sealant Between the Interior Panel of the Floor and the Frame

[0092] This joint was treated similarly to the previous one, using both a hinge and sealant, but with an increased hinge thickness in the floor area to ensure structural stability.

[0093] Hinge and Sealant Between the Large Wall and the Frame

[0094] As mentioned in the description of the large wall, we had a challenge to move the hinge axis while rotating. Initially, special hinges were designed for this part, so that the hinge core would move during movement and give us the exact path of movement in opening and closing the large wall. However, all the sketches made with a movable core were far from the primary goal of the subject, which was simplicity and practicality, and the user might even encounter problems with the maintenance and repair of the hinges in the future. Therefore, by developing a part of the geometry of the frame edge and finding a new axis of rotation, we could eliminate the displacement from the direction of movement of the large wall. Finally, we designed and placed a hinge with the exact usual single-axis mechanism and specific dimensions. Therefore, we solved the problem of axis displacement by changing the frame's geometry and not by designing a more complex hinge.

[0095] Hinge and Seal Between Small Wall and Frame

[0096] As described earlier, there was a challenge where the small wall would rub against the large wall and panels during opening, making the process difficult and potentially damaging. This issue was resolved at the top and bottom of the wall using a series of spring latches with a 3 cm offset. To address the alignment between the small and large walls, a hinge with a movable core was designed, capable of sliding 3 cm within its frame. As shown in, when the wall is closed, the hinge core is positioned at the end of the frame. After fully opening the wall, a built-in handle allows the user to slide the small wall 3 cm toward the large wall, locking the two walls together using the installed mechanism.

[0097] For other non-hinged joints, pre-designed sealants were applied to cover all remaining joints. Other requirements

[0098] After reviewing all the details, we will look at other requirements that provide greater comfort for the user and further improve the spatial cell. These requirements must be provided to the user along with the primary cell, but they should not, under any circumstances, add to the dimensions of the closed volume of the structure. Therefore, we designed these requirements in a folded form and placed them in boxes that are screwed to the frame structure in the space of the frame on both sides, opposite the large wall. We will examine these requirements in the following.

[0099] Furniture: First, we designed folding furniture that can be used as two beds, benches, desks, or other functions based on the user's needs. When closed, its total thickness is 9 cm. The dimensions of the box, the closing process, usage method, and measurements are illustrated ().

[0100] Flooring: In the open state, the interior floor of the structure remains within the frame section. Due to the separation of floor panels on both sides, an undesirable joint is formed. To address this, a floor covering was designed with a frame-aligned pattern and a warm foam top layer. It is divided into two parts for easier storage in the box and simpler placement on the floor. The covering is screwed onto the frame along with the furniture, stored in a separate box ().

[0101] • Ability to open and close the cells with a minimum workforce.

[0102] • Ability to open and close the cells without using a crane or specialized personnel.

[0103] • Ability to carry 8 main cells along with two service cells on a trailer, reducing costs and preventing time waste.

[0104] • Ability to remove the wall covering to place the cells together and create a more expansive space.

[0105] • Ability to store the cells without the need to stack them, which makes warehouse management easier

This method allows for quick, cost-effective, and portable implementation for a variety of uses.

[0203] Our final design can have various uses, depending on the predetermined purpose. For example, this invention can be used in temporary residential complexes, military camps, emergency shelters, and nature tourism camps. Due to its modular features and easy transportability, it can also be used in construction projects, temporary workshops, and educational and cultural spaces.

Claims

A temporary and portable structure with an easy and efficient opening and closing mechanism, without the need for specialized personnel or heavy tools, suitable for multipurpose applications such as temporary housing, emergency housing, nature camps, etc., this structure includes the following components:• The central core is designed as a frame• Large wallA360-degree wheelWall fixing lock• Small wallSpring latch• Roof panels•Floor panels• Hinge, Seal, and Joint DetailsCorner jointsHinges and seals between the large wall and the outer panel of the roof and floorHinges and seals between the inner and outer panels of the roof and floorHinges and seals between the inner panel of the roof, floor, and frameHinges and seals between the large wall, minor wall, and frame• and other requirementsAccording to claim 1, the central core is designed as a frame on both sides of which the walls and panels are symmetrically and rotated. They are located 180 degrees and, according to the design process diagrams, are opened and closed from both sides of the frame.According to claim 2, the designed frame consists of three parts: the roof, the floor, and the columns. Since all the components are ultimately hinged to these parts, its structure must be much more potent and able to withstand any twisting and shearing at the points of connection to the hinges.According to claim 1, the large wall of the structure, which is the last layer in the layering of walls and panels and has less reliance on the frame structure than other elements, and is placed in a slanted position with the help of vertical connections to the frame column in the open state.According to claim 4, a wheel is placed in the corner that can rotate 360 ​​degrees when opening the wall for the user's convenience. The wheel opens as soon as the wall is removed from the frame and easily allows it to be opened without the need for several specialized forces capable of bearing the weight of the wall.According to claim 1, the last member that opens and is placed on the axis closest to the axis of symmetry in the layering when closed is the small wall. The edges of the wall are offset inward by the amount needed to create a seam so that the opening and closing operations are carried out quickly, without the need for additional force to pull the wall, and without damaging the composite coverings.According to claim 6, the seals must be such that after the structure's opening is completed, all the edges created are sealed again. For this purpose, an all-around spring latch is designed for sealing between the small wall and the panels, and a type of hinge with a sliding core is for sealing between the small and large walls.According to claim 1, the details of the all-round spring latch are formed in the following order:

1. Designing a conventional spring latch mechanism that is closed and opened with a click (the click causes the handle to rotate in a defined direction, resulting in the closing and opening of the opening.)2. Creating interconnected pairs of designed latch mechanisms.

3. Putting six pairs of latches together, connecting them with a cover and sealant, and installing two handle positions in the formed row of latches (one row is placed at the top edge and one at the bottom edge of the wall.)With this created mechanism, we fill the offset of the top and bottom edges of the wall after opening by pressing both hands on the handles (one click) once at the bottom and once at the top.According to claim 1, the floor panels withstand more force (including weight force) than other parts. Therefore, to strengthen the structure of the floor panels, the grid of the panel profiles is made denser than the ceiling panels, and in addition, a 2 mm layer of iron sheet is considered for the final composite underlay.According to claim 1, all structural profile connections are generally made in two ways: Connection between two profiles with the same height sections: Cutting the engaged edges and connecting with a corner and connection between two profiles with different sections: The end of the profile with a smaller section is closed and directly screwed into the more prominent profile. Due to the intersection of the profiles with different and unequal angles, corners specific to each point were designed and cut from a 2 mm iron sheet and bent at an appropriate angle.According to claim 1, the hinge and seal between the large wall and the external roof panel, the way the wall and panel rotate relative to each other, the extruded rail, and the hinge seals have been designed in accordance with the angle and axis of rotation (close to the hinges available on the market).According to claim 1, the hinge and seal between the large wall and the outer floor panel are the same as the joint between the wall and the outer floor panel. Its hinge is the same as the hinge of claim 12 in terms of rotation, except that all hinges related to the floor are made thicker for greater strength.According to claim 1, a simple hinge with dimensions specific to its location was designed for the hinge and seal between the inner and outer ceiling panels. An extruded toothed seal was placed between the two panels, and for the final covering of the new joints created by the placement of the hinges, a rubber cover was finally fixed on all hinges with a latch so that the panels' opening and closing process was not disturbed.According to claim 1, the hinge and seal of the inner and outer floor panels are thicker than the hinge of claim 14, and there is no need for a cover to protect the newly created seams.According to claim 1, because the frame and the inner roof panel overlap, there is no need for a seal on both members. The seal is designed as an angled tooth that is compressed and sealed when the structure is opened.According to claim 1, for the hinge and seal in the large wall. Initially, special hinges were designed for this part so that during movement, the hinge core is displaced and gives us the exact path of movement in opening and closing the large wall. By developing a section of the geometry of the frame edge and finding a new axis of rotation, we could eliminate the displacement from the direction of movement of the large wall. Finally, a hinge with the usual single-axis mechanism was designed and placed with specific dimensions. Therefore, the problem of axis displacement was solved by changing the frame's geometry, and creating a more complex hinge was unnecessary.According to claim 1, when the small wall was opened, friction would occur between the large wall and the panels, which made opening the wall difficult and accompanied by damage. For this purpose, a series of spring latches with an offset of 3 cm were placed at the top and bottom of the wall, and to solve the problem of stretching the small wall to the large wall, a hinge with a movable core was designed, which is also capable of moving by 3 cm in its frame.According to claim 1, other necessities, such as furniture, provide more comfort to the user and further improve the spatial cell, and the necessities should be provided to the user along with the main cell. These necessities are designed to be assembled and placed in boxes that are screwed to the frame structure in the space of the frame on both sides opposite the large wall.According to claim 18, foldable furniture was designed to be used as 2 beds, a bench, a desk, etc., according to the user's needs. Its total thickness in the closed state is 9 cm.According to claim 18, the floor of the structure's interior space is in an open state in the frame part due to the separation of the floor panels on both sides, which creates a plug-like state, which is naturally undesirable for use. To solve this problem, a floor covering with a frame floor pattern, with warm foam on top, was designed and divided into two parts (for placement in the box and easier placement on the floor) and screwed onto the frame together with the furniture in another box.
