Description

Seats and chairs

[0001] Cross-referencing

[0002] This application incorporates Chinese Patent Application No. 202421701353.X, entitled “Chair”, filed on July 17, 2024, which is incorporated herein by reference in its entirety. Technical Field

[0003] This application relates to the field of seating, and more particularly to a chair seat and a chair. Background Technology

[0004] Due to the poor breathability of sponge chair seats, many people have designed different mesh chair seats. The structure of mesh chair seats mainly includes the following two types: One type includes a plastic support frame fixed to the chair's base, an inner frame inside the plastic support frame, and taut mesh fabric fixed around the inner frame. The inner frame with the mesh fabric fixed is then placed inside the plastic support frame and secured using fasteners or screws. The other type includes a plastic support frame fixed to the chair's base, with a groove of a specific width around the perimeter of the plastic support frame. Adhesive strips of a specific thickness are sewn around the perimeter of the mesh fabric of a corresponding shape, and the adhesive strips with the mesh fabric sewn into the grooves around the plastic support frame and secured.

[0005] The advantages of the two mesh seat structures mentioned above are that they are more breathable than traditional foam seats, but they also have disadvantages such as poor comfort, easy loss of elasticity leading to permanent deformation or even collapse, high after-sales costs, and complicated disassembly and assembly.

[0006] Summary of the Invention

[0007] Therefore, it is necessary to provide a seat and a chair.

[0008] On the one hand, a chair seat is provided, comprising:

[0009] Support the main body;

[0010] The seat body includes a seat frame and a mesh fabric covering one side of the seat frame; the seat frame is movably connected to the support body and has an open position and a closed position relative to the support body; and

[0011] An elastic element is disposed between the support body and the mesh fabric to allow for elastic deformation and to disperse the pressure on the mesh fabric.

[0012] When the seat frame is in the open position, it is open relative to the support body to form an opening for taking in and taking out the elastic element; when the seat frame is in the closed position, it is closed relative to the support body and together with the mesh fabric, it forms a receiving cavity for accommodating the elastic element.

[0013] In the chair seat described above, both the mesh fabric and the elastic element provide support when the user sits on it. The elastic element, after deformation under stress, disperses the pressure on the mesh fabric, reducing its tension and improving seat comfort. Simultaneously, as the pressure on the mesh fabric decreases, its deformation also decreases, keeping it within its elastic limit. This ensures that the mesh fabric will not permanently deform or collapse due to loss of resilience after prolonged use, improving the chair seat's reliability and lifespan. When the user needs to adjust the seat's comfort, the seat frame is switched from the closed position to the open position to create a retrieval port. The user can then replace or adjust the elastic element according to their own needs (e.g., weight and sitting posture), allowing the elastic element to disperse different levels of pressure and ensuring the pressure on the mesh fabric remains within a comfortable range, improving the chair seat's practicality. After the elastic element is replaced or adjusted, the seat frame is returned to the closed position. The seat frame, mesh fabric, and support body together form a cavity for accommodating the elastic element, making operation simple and convenient.

[0014] The technical solution will be further explained below:

[0015] In one embodiment, the seat frame is rotatably connected to the support body and is capable of switching between an open position and a closed position relative to the support body.

[0016] In one embodiment, one side of the seat frame is rotatably connected to one side of the support body.

[0017] In one embodiment, a first mounting portion and a second mounting portion are respectively provided at the position where the seat frame and the support body are connected. The first mounting portion has a first mounting hole, and the second mounting portion has a second mounting hole. The second mounting hole is corresponding to the first mounting hole. The chair seat also includes a rotating shaft, which passes through the first mounting hole and the second mounting hole and rotatably connects the first mounting portion and the second mounting portion.

[0018] In one embodiment, a third mounting portion is further provided at the position where the seat frame connects to the support body. The third mounting portion and the first mounting portion are spaced apart on both sides of the second mounting portion along the axial direction of the first mounting hole. The side of the third mounting portion near the second mounting portion is provided with a blind hole corresponding to the second mounting hole. The rotating shaft extends into the blind hole and is limited and engaged with the inner wall of the blind hole.

[0019] In one embodiment, the seat further includes a locking member for locking the seat frame to the support body when the seat frame is in the closed position.

[0020] In one embodiment, the locking member is mounted on the support body, the seat frame has a plug-in portion extending toward the support body, and the support body has a first slot corresponding to the plug-in portion. When the seat frame is in the closed position, the plug-in portion is plugged into the first slot, and the locking member is used to lock the plug-in portion and the support body in a locked engagement.

[0021] In one embodiment, the plug portion is provided with a second slot, and the inner sidewall of the first slot is provided with a locking hole. The locking member is slidably engaged with the support body so that it can pass through the locking hole and extend into the second slot when the seat frame is in the closed position.

[0022] In one embodiment, the locking member is provided with an operating part for receiving a driving force that causes the locking member to slide relative to the support body along the axial direction of the lock hole.

[0023] In one embodiment, the support body is provided with at least one vent hole, each of the vent holes being configured to communicate with the receiving cavity when the seat frame is in the closed position.

[0024] In one embodiment, the elastic element includes a spring layer.

[0025] In one embodiment, the elastic element comprises a TPE material layer.

[0026] In one embodiment, the elastic element includes a sponge layer.

[0027] In one embodiment, the elastic element includes a 3D breathable material layer.

[0028] On the other hand, a chair is provided, including a chair frame and a seat, the seat being mounted on the chair frame.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] The inventor, through research and testing, discovered the following significant drawbacks in the two main mesh seat structures on the market:

[0038] 1. The comfort of the mesh chair seat needs to be improved. When a user sits on a foam chair seat, the weight of the body is distributed from top to bottom on the foam in contact. However, for the mesh chair seat, the weight of the upper part of the user's body is pressed on the suspended mesh fixed around the chair seat, causing the mesh to be evenly taut. This not only reduces the pressure area but also increases the pressure on the unit pressure point. At the same time, the user is sitting on a taut, hard material, so the comfort is naturally not very good.

[0039] 2. After prolonged use, the suspended mesh fabric of these mesh chair seats is prone to losing its elasticity, permanent deformation, or even collapse, especially when the user is relatively heavy.

[0040] 3. Since the mesh fabric and plastic support frame of the mesh chair seat are fixedly connected, if the mesh fabric deforms or collapses and the chair seat needs to be replaced after the service, the entire chair seat, including the plastic support frame, needs to be replaced. This not only results in high material costs for after-sales service, but also relatively expensive shipping costs, and the disassembly and assembly are also quite complicated.

[0041] Based on this, the following embodiments of the chair and seat of this application are proposed to solve the above-mentioned technical problems.

[0042] As shown in Figures 1, 2, and 3, in one embodiment, a chair seat 10 is provided, including a support body 100, a seat body 200, and an elastic element 300. The seat body 200 includes a seat frame 210 and a mesh fabric 220 covering one side of the seat frame 210. The seat frame 210 is movably connected to the support body 100 and has an open position and a closed position relative to the support body 100. The elastic element 300 is disposed between the support body 100 and the mesh fabric 220 to elastically deform and disperse pressure on the mesh fabric 220. When the seat frame 210 is in the open position, it opens relative to the support body 100 to form a slot 410 for taking in and taking out the elastic element 300. When the seat frame 210 is in the closed position, it closes relative to the support body 100 and, together with the mesh fabric 220, forms a receiving cavity 420 for accommodating the elastic element 300.

[0043] In the above embodiment, when a user sits on the chair seat 10, both the mesh fabric 220 and the elastic element 300 can provide support. After the elastic element 300 deforms under force, it can disperse the pressure on the mesh fabric 220, thereby reducing the tension of the mesh fabric 220 and improving the comfort of the chair seat 10. At the same time, when the pressure on the mesh fabric 220 decreases, its deformation also decreases accordingly, keeping the deformation of the mesh fabric 220 within the elastic limit. This ensures that the mesh fabric 220 will not undergo permanent deformation or even collapse due to loss of resilience after long-term use, thus improving the reliability and service life of the chair seat 10. When the user needs to adjust the comfort of the seat 10, the seat frame 210 is switched from the closed position to the open position to form a retrieval port 410. The user can replace or adjust the elastic element 300 according to their own situation (such as weight and sitting posture habits) through the retrieval port 410, so that the elastic element 300 can distribute different levels of pressure, ensuring that the pressure on the mesh fabric 220 is kept within a comfortable range, thus improving the practicality of the seat 10. After the elastic element 300 is replaced or adjusted, the seat frame 210 is returned to the closed position. The seat frame 210, mesh fabric 220, and support body 100 together form a receiving cavity 420 for accommodating the elastic element 300, making the operation simple and convenient.

[0044] The support body 100 can be configured as a support frame, support plate or other support structure, and the mesh 220 can be wrapped around one side of the seat frame 210 in any way in the prior art, without limitation.

[0045] As shown in Figures 2 and 3, optionally, the support body 100 is provided with at least one vent 111, and each vent 111 is configured to communicate with the receiving cavity 420 when the seat frame 210 is in the closed position. In this way, the receiving cavity 420 can communicate with the external environment through the vent 111, thereby improving the air permeability of the seat 10.

[0046] Specifically, in this embodiment, each vent 111 extends from the top wall of the support body 100 to the bottom wall of the support body 100. All vents 111 are arranged in an array on the support body 100.

[0047] The elastic element 300 can be configured as any type of elastic structure in the prior art. The elastic element 300 can be configured as a single-layer structure, a double-layer structure, or a multi-layer structure.

[0048] Optionally, the elastic element 300 includes a spring layer. The elastic layer includes a plurality of vertically arranged springs. All springs are arranged in an array.

[0049] Optionally, the elastic element 300 includes a TPE (Thermoplastic elastomer) material layer. The TPE material layer is honeycomb-shaped.

[0050] Optionally, the elastic element 300 includes a sponge layer. The sponge layer can be a regular sponge layer or a memory foam layer. Perforations are drilled in the sponge layer.

[0051] Optionally, the elastic element 300 includes a 3D breathable material layer.

[0052] Specifically, in this embodiment, the elastic element 300 is clamped between the mesh fabric 220 and the support body 100. In this way, the position of the elastic element 300 relative to the mesh fabric 220 remains fixed, which can stably distribute the pressure and improve the reliability of the chair seat 10.

[0053] As shown in Figures 1, 2, and 3, in one embodiment, the seat frame 210 is rotatably connected to the support body 100 and can switch between an open position and a closed position relative to the support body 100. Thus, the seat frame 210 can quickly and accurately switch between the open and closed positions, improving the practicality of the chair seat 10.

[0054] In this embodiment, one side of the seat frame 210 is rotatably connected to one side of the support body 100. The seat frame 210 and the support body 100 are detachable. In other embodiments, the seat frame 210 may also be slidably connected to the support body 100 and can switch between an open position and a closed position relative to the support body 100.

[0055] As shown in Figure 3, furthermore, a first mounting part 211 and a second mounting part 112 are respectively provided at the connection positions between the seat frame 210 and the support body 100. The first mounting part 211 has a first mounting hole 212, and the second mounting part 112 has a second mounting hole 113, which are correspondingly arranged with the first mounting hole 212. The chair seat 10 also includes a rotating shaft 213, which passes through the first mounting hole 212 and the second mounting hole 113, and rotatably connects the first mounting part 211 and the second mounting part 112. In this way, the first mounting part 211, the second mounting part 112, and the rotating shaft 213 are detachable, so that the seat frame 210 and the support body 100 can be replaced individually according to actual use needs, which facilitates the maintenance and after-sales service of the chair seat 10 and reduces the after-sales cost of the chair seat 10.

[0056] As shown in Figure 3, optionally, a third mounting portion 214 is provided at the connection position between the seat frame 210 and the support body 100. The third mounting portion 214 and the first mounting portion 211 are spaced apart on both sides of the second mounting portion 112 along the axial direction of the first mounting hole 212. The side of the third mounting portion 214 closest to the second mounting portion 112 has a blind hole 215 corresponding to the second mounting hole 113. The rotating shaft 213 extends into the blind hole 215 and is limited and engaged with the inner wall of the blind hole 215. In this way, the blind hole 215 can play a positioning role for the rotating shaft 213, ensuring that the rotating shaft 213 can be quickly and accurately installed to the preset position, and rotate and engage with the first mounting portion 211, the second mounting portion 112 and the third mounting portion 214, improving the convenience of assembling the chair seat 10.

[0057] Specifically, in this embodiment, the first mounting part 211 and the third mounting part 214 are both correspondingly disposed on the seat frame 210, and the second mounting part 112 is correspondingly disposed on the support body 100. In other embodiments, the first mounting part 211 and the third mounting part 214 may also be correspondingly disposed on the support body 100, and the second mounting part 112 may be correspondingly disposed on the seat frame 210.

[0058] As shown in Figures 2 and 3, in one embodiment, the chair seat 10 further includes a locking member 500, which is used to lock the seat frame 210 to the support body 100 when the seat frame 210 is in the closed position. In this way, the locking member 500 can lock the seat frame 210 and the support body 100 into a single unit, ensuring that there is no relative movement between the seat frame 210 and the support body 100 during use, thus improving the reliability of the chair seat 10.

[0059] The locking element 500 can be a clamp, latch, bolt, or other locking structure. The locking element 500 can be installed on either side of the support body 100. Specifically, in this embodiment, the locking element 500 is installed on the side of the support body 100 away from the second mounting part 112.

[0060] As shown in Figures 2 and 3, the locking member 500 is further installed on the support body 100. The seat frame 210 has a plug-in portion 216 extending toward the support body 100, and the support body 100 has a first slot 114 corresponding to the plug-in portion 216. When the seat frame 210 is in the closed position, the plug-in portion 216 is engaged with the first slot 114, and the locking member 500 is used to lock the plug-in portion 216 to the support body 100. In this way, the locking member 500 can lock the seat frame 210 and the support body 100 together through the plug-in portion 216, improving the convenience of assembling the chair seat 10.

[0061] In other embodiments, the locking member 500 and the first slot 114 may also be correspondingly disposed on the seat frame 210, and the plug-in part 216 may be correspondingly disposed on the support body 100. Their structure and working principle are the same or similar to those described above, and will not be described in detail here.

[0062] As shown in Figures 2 and 3, optionally, the insertion part 216 is provided with a second slot 217, and the inner sidewall of the first slot 114 is provided with a locking hole 115. The locking member 500 is slidably engaged with the support body 100 so that it can pass through the locking hole 115 and extend into the second slot 217 when the seat frame 210 is in the closed position. In this way, the locking member 500 and the support body 100 are integrated, which facilitates locking the seat frame 210 and the support body 100 while reducing the installation space of the locking member 500 and improving the practicality of the chair seat 10.

[0063] In this specific embodiment, the plug-in portion 216 can be configured as a plug block. The plug-in portion 216 is integrally formed with the seat frame 210. The second slot 217 passes through the plug-in portion 216.

[0064] As shown in Figures 2 and 3, optionally, the locking member 500 is provided with an operating part 510, which is used to receive the driving force that causes the locking member 500 to slide relative to the support body 100 along the axial direction of the lock hole 115. In this way, the operating part 510 can receive external driving force to drive the locking member 500 to slide back and forth relative to the support body 100 along the axial direction of the lock hole 115, thereby improving the practicality of the chair seat 10.

[0065] In this specific embodiment, the operating unit 510 can be configured as an operating handle.

[0066] In one embodiment, a chair is provided, including a chair frame and a seat 10 as described in any of the above embodiments, the seat 10 being mounted on the chair frame.
