Description

Technical Field

[0001] The present invention relates to a foldable iron frame sofa chair, and more particularly to a foldable iron frame sofa chair applicable to the field of sofa chairs. Background Technology

[0002] A sofa chair is a piece of furniture that combines the comfort of a seat with the functionality of a sofa. It is commonly used in living rooms, sitting rooms, and leisure areas. Combining the spaciousness and comfort of a sofa with the support and posture of a chair, it provides an ideal space for rest and relaxation. Sofa chairs also have many other features and functions, such as adjustable backrest angles, extendable footstools, and folding mechanisms. Furthermore, there are many options for the appearance of sofa chairs; different materials (such as leather, fabric, or textiles), colors, and patterns can be chosen according to personal preferences and interior design styles. In short, a sofa chair is a comfortable, practical, and multifunctional piece of furniture that provides people with a comfortable seating posture and a relaxing space. Whether for rest, entertainment, or socializing, a sofa chair is an indispensable part of the home. Due to limited space in modern homes, the folding function of sofa chairs is particularly important.

[0003] To address the issue of sofa and chair folding, a certain chair extension frame and chair extension device on the market adopts a chair extension device design and has a certain market share.

[0004] Chinese invention patent CN202210789454.6 discloses a seat extension frame and seat extension device with arbitrarily adjustable posture. This application relates to the technical field of functional sofa mechanical extension frames, and particularly to a seat extension frame with arbitrarily adjustable posture, including a base frame and an extension support. The extension support includes a seat frame on the base frame, a leg extension component and a backrest frame rotatably connected to the seat frame, and a support component between the base frame and the seat frame. The base frame, seat frame, and support component are combined to form a first crank rocker structure. A lifting component is provided between the front support component and the leg extension component, and a backrest support structure is provided between the backrest frame, the rear support component, and the base frame. The deformation of the first crank rocker structure drives the seat frame and the lifting component to control the extension and retraction of the leg extension component, and the deformation of the first crank rocker structure drives the backrest support structure to control the angle rotation of the backrest frame. This allows for arbitrary adjustment of the seat posture while reducing the number of components. The structure is simple, easy to operate, convenient to maintain, and has low manufacturing cost.

[0005] While existing sofas and chairs have simplified folding and adjustment mechanisms, they still have certain limitations. When folding or storing them, due to structural design limitations, space cannot be used effectively. At the same time, since the contact area with the ground is fixed, the sofa and chair can easily damage the ground when used by heavier people.

[0006] Application content

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that it is easy to fold and adjust, and can automatically increase support, increase the contact area between the sofa and the ground, and can protect the ground.

[0008] To address the aforementioned problems, this invention provides a foldable iron-framed sofa chair, comprising a leg frame, multiple connecting blocks fixedly connected to the leg frame, a first support rotatably connected to the multiple connecting blocks, a second support housed within the first support, a third support housed within the second support, a fourth support housed within the third support, and a fifth support housed within the fourth support. A first elastic cord is fixedly connected to each of the multiple connecting blocks, and the first elastic cord sequentially passes through the second, third, fourth, and fifth supports. The first, second, third, fourth, and fifth supports are fixedly connected by the second elastic cord. A baffle is snapped onto one end of each of the second, third, fourth, and fifth supports. The end of the first support away from the baffle is covered with the seat surface, and the other end of the first support is covered with the backrest material.

[0009] In the aforementioned foldable iron-framed sofa chair, the elastic rope support and multiple connecting blocks ensure that each support remains vertical, providing a stable seat structure. The baffle design not only serves as a shelf but also increases stability when someone is sitting on the chair, preventing damage to the ground. It has the advantages of saving space, providing stable support, multi-layered structure, and functionality.

[0010] As a further improvement of this application, the chair surface includes an elastic parallel mesh fixedly connected to the first support, a breathable elastic layer fixedly connected to the elastic parallel mesh, and an elastic fabric layer fixedly connected to the breathable elastic layer. Multiple through holes are provided on the elastic parallel mesh, the breathable elastic layer, and the elastic fabric layer.

[0011] The elastic parallel mesh is part of the chair surface and is fixedly connected to the first support. The elastic parallel mesh has a certain degree of elasticity and flexibility, which can provide a comfortable sitting feel and support. It can adapt to the user's body curves and distribute pressure, reducing the pressure on the body when sitting for a long time.

[0012] The breathable elastic layer is one of the layers fixedly connected to the elastic parallel mesh. This layer has breathable properties, which can promote air circulation, provide ventilation, and prevent the chair surface from overheating and causing discomfort.

[0013] The elastic fabric layer is the outermost layer of the chair surface, connected to the breathable elastic layer. This layer is usually made of soft, comfortable fabric material with a certain degree of elasticity, which can further increase the comfort and texture of the chair surface.

[0014] The perforations in the elastic parallel mesh, breathable elastic layer, and elastic fabric layer serve to ventilate and dissipate heat, enhancing the breathability of the chair surface, allowing air circulation, and providing a more comfortable and refreshing seating experience.

[0015] As a further improvement of this application, the backrest material includes a pressure-bearing layer fixedly connected to the first support, and a sealing layer is fixedly connected to the end of the pressure-bearing layer away from the first support.

[0016] The pressure layer is part of the backrest material and is fixedly connected to the first support. Its function is to provide back support and comfort. The pressure layer can be adjusted and adapted according to the user's back curve and pressure distribution to provide customized support and reduce back fatigue.

[0017] The sealing layer is located at the end of the pressure layer away from the first support and is fixedly connected to the pressure layer. The function of the sealing layer is to maintain the integrity and stability of the pressure layer. It can prevent the pressure layer from deforming or loosening during use and maintain the shape and support effect of the chair back.

[0018] As a further improvement of this application, the ends of the multiple baffles furthest from the first support are all wedge-shaped structures, and the wedge-shaped structures are set at an angle.

[0019] The wedge structure provides better stability, allowing the baffle to withstand greater pressure and weight during use, reducing the possibility of tilting and swaying. The angle of the wedge structure is set to degrees, which can effectively balance the load, making the baffle more evenly distributed when bearing pressure, reducing the problem of pressure concentration, improving the stability and service life of the chair. The design of the wedge structure allows the baffle to make better use of space when folded or in a vertical state, saving storage and transportation space.

[0020] As another improvement of this application, the first support, the second support, the third support, the fourth support and the fifth support are nested together and are all made of hollow tubular material. The adjacent gaps of the first support, the second support, the third support, the fourth support and the fifth support are filled with highly elastic sponge.

[0021] By nesting the different supports, space can be saved by placing them more compactly. This makes the sofa chair easier to fold or store, and the nesting between the supports provides greater structural stability, making the sofa chair more sturdy and reliable in use.

[0022] Hollow tubular materials are lighter than solid materials, thus reducing the overall weight of the sofa and chair, making them easier to move and transport. The hollow structure utilizes the space of the material, reducing the amount of material needed and achieving the effect of saving resources.

[0023] High-elasticity foam filling provides a better seating feel and support, making users feel more comfortable when using sofas and chairs. High-elasticity foam has good shock absorption and cushioning properties, which can reduce the impact and pressure when sitting down and protect the body from discomfort.

[0024] As a further improvement to this application, a wear-resistant material is provided between the connecting block and the first bracket, and the wear-resistant material is snapped into the connecting block.

[0025] Wear-resistant materials can reduce wear between the connecting block and the first bracket, extending their service life. When friction or contact occurs between the connecting block and the first bracket, the wear-resistant material can withstand wear and friction, preventing premature wear or breakage of parts. Wear-resistant materials can reduce noise and vibration between the connecting block and the first bracket, providing a smoother and quieter user experience. The snap-fit ​​design ensures a secure and stable connection between the wear-resistant material and the connecting block, preventing them from loosening or falling off during use. The snap-fit ​​design makes the wear-resistant material relatively easy to maintain and replace. If wear or damage occurs, the wear-resistant material can be easily replaced, extending the overall service life.

[0026] As a further improvement to this application, the first elastic rope passes through the leg near the connecting block, and the passing part is snapped into the leg.

[0027] The first elastic cord running through the legs increases the strength and stability of the entire structure, ensuring that the sofa chair can withstand greater pressure and load during use. The first elastic cord allows the legs to distribute force evenly, providing better support and making the seat more comfortable and stable. The first elastic cord and the legs are connected by a snap-fit ​​mechanism, ensuring a secure and stable connection and preventing them from loosening or falling off during use. Furthermore, the installation and adjustment of the first elastic cord are relatively easy, facilitating assembly, maintenance, and tension adjustment.

[0028] As another improvement of this application, multiple tripods are fixedly connected by a connecting plate, and the connecting plate is snapped into the connecting block.

[0029] Connecting multiple legs with connecting plates increases the stability of the entire base, preventing the sofa from wobbling or tilting during use, providing a safer seating posture and support. The connecting plates distribute the weight and pressure of the body across multiple legs, reducing the load on individual legs and improving the overall load-bearing capacity. The connecting plates and connecting blocks use a snap-fit ​​design, ensuring a secure and stable connection between the connecting plates and connecting blocks, preventing them from loosening or falling off during use, and increasing the stability of the entire structure. The snap-fit ​​design also makes the installation and disassembly of the connecting plates relatively easy, facilitating assembly, maintenance, and replacement.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. Space saving: This sofa chair has a foldable iron frame structure with nested supports made of hollow tubular material and filled with high-elasticity sponge, making it more convenient to fold or store and saving space.

[0032] 2. Stable structure: Supported by elastic ropes and multiple connecting blocks, each bracket remains vertical, providing a stable seat structure. The wedge-shaped structure of the baffle and the setting of 30 to 50 degrees increase stability and reduce the possibility of tilting and swaying.

[0033] 3. Multifunctional design: The baffle can not only be used as a shelf, but also increases stability when someone is sitting on the chair and prevents damage to the ground. The design of elastic parallel mesh, breathable elastic layer and elastic fabric layer provides a comfortable sitting feel and support, and the through-hole setting increases the ventilation and heat dissipation of the seat surface.

[0034] 4. Self-cleaning function: The back panel material includes a pressure layer and a sealing layer. When a person leaves the sofa, the pressure layer, sealing layer and other materials move forward together to form a cavity. During the rebound of the sealing layer, the gas in the cavity flows out through the through holes, cleaning the dust on the seat surface and other materials, thus achieving the self-cleaning function.

[0035] 5. Durability and comfort: The use of wear-resistant materials reduces wear between the connecting block and the first support, extending service life. High-elasticity sponge filling provides a comfortable seating feel and support. The entire structure is sturdy and durable, capable of withstanding pressure and weight. Attached Figure Description

[0049] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0050] First implementation method:

[0051] Figure 1 , Figure 4 , Figure 5 and Figure 8 The illustration shows a foldable iron-framed sofa chair, including a leg frame 1. Multiple connecting blocks 2 are fixedly connected to the leg frame 1. A first support 3 is rotatably connected to the multiple connecting blocks 2. A second support 4 is provided inside the first support 3. A third support 5 is provided inside the second support 4. A fourth support 6 is provided inside the third support 5. A fifth support 7 is provided inside the fourth support 6. A first elastic rope 8 is fixedly connected to each of the multiple connecting blocks 2. The first elastic rope 8 passes through the second support 4, the third support 5, the fourth support 6 and the fifth support 7 in sequence. The first support 3, the second support 4, the third support 5, the fourth support 6 and the fifth support 7 are fixedly connected by a second elastic rope 13. A baffle 9 is snapped onto one end of the second support 4, the third support 5, the fourth support 6 and the fifth support 7. The end of the first support 3 away from the baffle 9 is covered with a seat surface 10. The other end of the first support 3 is covered with a backrest material 11.

[0052] Figure 4As shown: When not in use, since the connecting block 2 is rotatably connected to the second bracket 4 and the connecting block 2 is fixedly connected to the first elastic rope 8, the second bracket 4, the third bracket 5, the fourth bracket 6 and the fifth bracket 7 remain perpendicular to the first bracket 3 under the elastic force of the first elastic rope 8. At this time, the second bracket 4, the third bracket 5, the fourth bracket 6 and the fifth bracket 7 are on the same plane, and the baffles 9 on the second bracket 4, the third bracket 5, the fourth bracket 6 and the fifth bracket 7 are parallel to each other. At this time, the multiple baffles 9 can be used as shelves.

[0053] Figure 1 , Figure 5 and Figure 8 The diagram shows that when someone uses the chair, under the pressure of the human body, the second support 4, the third support 5, the fourth support 6, and the fifth support 7 will move towards the baffle 9 until they are at a 30-50 degree angle to the first support 3. Then, under the pressure of the human body, the third support 5, the fourth support 6, and the fifth support 7 will move backward in sequence. During the movement, the baffle 9 on the third support 5, the fourth support 6, and the fifth support 7 will come into contact with the ground in sequence. The contact between the baffle 9 and the ground can improve the stability of the sofa chair and increase the contact area between the sofa chair and the ground, making it less likely for the sofa chair to damage the ground when someone uses it.

[0054] In the aforementioned foldable iron frame sofa chair, each support is kept vertical by elastic rope support and multiple connecting blocks 2, providing a stable seat structure. The baffle 9 design not only serves as a shelf, but also increases stability when someone is sitting on the chair, preventing damage to the ground. It has the advantages of saving space, providing stable support, multi-layer structure and functionality.

[0055] Second implementation method:

[0056] Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11As a further improvement of this application, the chair surface 10 includes an elastic parallel mesh 101 fixedly connected to the first support 3. A breathable elastic layer 102 is fixedly connected to the elastic parallel mesh 101, and an elastic fabric layer 103 is fixedly connected to the breathable elastic layer 102. Multiple through holes 104 are provided on the elastic parallel mesh 101, the breathable elastic layer 102, and the elastic fabric layer 103. The backrest material 11 includes a pressure-bearing layer 111 fixedly connected to the first support 3. A sealing layer 112 is fixedly connected to the end of the pressure-bearing layer 111 away from the first support 3. Multiple baffles 9 have a wedge-shaped structure at the end away from the first support 3, and the wedge-shaped structure... The structure is set at an angle of 30 to 50 degrees. The first support 3, the second support 4, the third support 5, the fourth support 6, and the fifth support 7 are nested together and are all made of hollow tubular material. The adjacent gaps of the first support 3, the second support 4, the third support 5, the fourth support 6, and the fifth support 7 are filled with high elastic sponge 12. A wear-resistant material is provided between the connecting block 2 and the first support 3, and the wear-resistant material is snapped into the connecting block 2. The first elastic rope 8 passes through the leg 1 near the connecting block 2 and the passing part is snapped into the leg 1. The multiple legs 1 are fixedly connected by a connecting plate, and the connecting plate is snapped into the connecting block 2.

[0057] Figure 1 , Figure 5 , Figure 6 and Figure 8 The diagram illustrates that when someone sits on the sofa chair, the weight of the person pushes the seat 10 backward. At this time, the elastic parallel mesh 101, breathable elastic layer 102, elastic fabric layer 103, pressure-bearing layer 111, sealing layer 112, and high-elasticity sponge 12 move backward together. When the person leaves the sofa chair, the elastic parallel mesh 101, breathable elastic layer 102, elastic fabric layer 103, pressure-bearing layer 111, sealing layer 112, and high-elasticity sponge 12 move forward together. Since the sealing layer 112 has a slower air permeability compared to other materials, it is the last to rebound. This creates a cavity between the sealing layer 112 and other materials, containing a large amount of gas. As the sealing layer 112 rebounds, it compresses the gas in the cavity, causing the gas to flow out through multiple through holes 104. During the outflow process, the gas cleans the dust on the seat 10 and other materials, enabling the sofa chair to self-clean after each use.

[0058] Figure 1 and Figure 10As shown: the elastic parallel mesh 101 is part of the seat surface 10 and is fixedly connected to the first support 3. The elastic parallel mesh 101 has a certain degree of elasticity and flexibility, which can provide a comfortable sitting feel and support. It can adapt to the user's body curves and distribute pressure, reducing the pressure on the body when sitting for a long time. The breathable elastic layer 102 is one of the layers fixedly connected to the elastic parallel mesh 101. This layer has breathable properties, which can promote air circulation, provide ventilation, and prevent the seat surface 10 from overheating and causing discomfort. The elastic fabric layer 103 is the outermost layer of the seat surface 10 and is connected to the breathable elastic layer 102. This layer is usually made of soft and comfortable fabric material with a certain degree of elasticity, which can further increase the comfort and texture of the seat surface 10. The through holes 104 opened in the elastic parallel mesh 101, the breathable elastic layer 102, and the elastic fabric layer 103 have the function of ventilation and heat dissipation. They can enhance the breathability of the seat surface 10, allow air circulation, and provide a more comfortable and refreshing seating experience.

[0059] Figure 1 and Figure 10 As shown: The pressure-bearing layer 111 is part of the backrest material 11 and is fixedly connected to the first support 3. Its function is to provide back support and comfort. The pressure-bearing layer 111 can be adjusted and adapted according to the user's back curve and pressure distribution to provide customized support and reduce back fatigue. The sealing layer 112 is located at the end of the pressure-bearing layer 111 away from the first support 3 and is fixedly connected to the pressure-bearing layer 111. The function of the sealing layer 112 is to maintain the integrity and stability of the pressure-bearing layer 111. It can prevent the pressure-bearing layer 111 from deforming or loosening during use, maintain the shape and support effect of the chair back. The wedge structure can provide better stability, allowing the baffle 9 to withstand greater pressure and weight during use, reducing the possibility of tilting and swaying. The angle of the wedge structure is set to 30 degrees to 50 degrees, which can effectively balance the load, making the baffle 9 more evenly distributed when bearing pressure, reducing the problem of pressure concentration, improving the stability and service life of the chair. The design of the wedge structure allows the baffle 9 to make better use of space when folded or in a vertical state, saving storage and transportation space.

[0060] Figure 6 and Figure 7As shown: Through nesting, different supports can be placed more compactly, saving space and making the entire sofa chair more convenient to fold or store. The nesting between the supports provides stronger structural stability, making the sofa chair more sturdy and reliable in use. The hollow tubular material is lighter than solid material, thus reducing the overall weight of the sofa chair and making it easier to move and transport. The hollow structure utilizes the space of the material, reducing the amount of material required and achieving the effect of saving resources. The high-elasticity sponge 12 filling provides better seating feel and support, making users feel more comfortable when using the sofa chair. The high-elasticity sponge 12 has good shock absorption and cushioning performance, which can reduce the impact and pressure when sitting down and protect the body from discomfort.

[0061] Wear-resistant materials can reduce wear between connecting block 2 and first bracket 3, extending their service life. When friction or contact occurs between connecting block 2 and first bracket 3, wear-resistant materials can withstand wear and friction, preventing premature wear or breakage of parts. Wear-resistant materials can reduce noise and vibration between connecting block 2 and first bracket 3, providing a smoother and quieter user experience. The snap-fit ​​design ensures a secure and stable connection between wear-resistant materials and connecting block 2, preventing them from loosening or falling off during use. The snap-fit ​​design makes it relatively easy to maintain and replace wear-resistant materials. If wear or damage occurs, wear-resistant materials can be easily replaced, extending the overall service life.

[0062] The first elastic cord 8, running through the leg 1, increases the strength and stability of the entire structure, ensuring the sofa chair can withstand greater pressure and load during use. The first elastic cord 8 also allows for even distribution of force on the leg 1, providing better support and making the seat more comfortable and stable. The first elastic cord 8 and leg 1 are connected by a snap-fit ​​mechanism, ensuring a secure and stable connection and preventing loosening or detachment during use. Furthermore, the first elastic cord 8 is relatively easy to install and adjust, facilitating assembly, maintenance, and tightness adjustment. The connecting plate connects multiple legs 1, which can increase the stability of the entire base, prevent the sofa chair from wobbling or tilting during use, and provide a safer sitting posture and support. The connecting plate can distribute the weight and pressure of the human body to multiple legs 1, reduce the load borne by a single leg 1, and improve the overall load-bearing capacity. The connecting plate and the connecting block 2 adopt a snap-fit ​​setting, which can ensure the fastening and stability between the connecting plate and the connecting block 2, prevent them from loosening or falling off during use, and increase the stability of the entire structure. The snap-fit ​​setting makes the installation and disassembly of the connecting plate relatively easy, and facilitates assembly, maintenance and replacement.

[0063] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
