Description

Technical Field

[0001] The invention relates to the technical field of seat installation, in particular to a chair capable of automatically installing fabric and a supporting frame. Background Art

[0002] With the rapid development of network technology, online shopping is becoming more and more popular. When transporting items, the smaller the space they occupy in a fixed space transport device, the easier it is to transport them, increase the amount of goods transported in a single trip, and reduce transportation costs. Chairs are an indispensable part of daily life. When transporting chairs, they are generally disassembled into smaller components. After the goods arrive, they are assembled on site by the purchaser or professional assemblers. Generally speaking, the more elaborate the disassembly of the chair, the more difficult it is to install; and the seat structure and support structure of the chair occupy a large space, which increases the space and cost of transportation.

[0003] The commonly used detachable seats now mainly include three parts: base, backrest and cushion. Depending on the needs of customers, you can also choose to purchase seats with more functions. At the same time, it will increase the difficulty of installation and transportation cost of the seats. The connection between the base and the cushion of conventional seats is mainly direct connection, that is, the base directly supports the cushion, and its force direction is exactly the same as the direction of gravity. With this connection method, the base bears the entire load-bearing capacity of the seat. When the load-bearing capacity exceeds the bearing range of the base material, the support rod or telescopic device between the base and the cushion will cause harm to the user, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide a chair with self-installed fabric and support frame, which occupies a small space during transportation, is light in weight, can change the direction of force, and is safe to use.

[0005] The technical solution adopted by the present invention to solve its technical problem is to propose a chair with self-installed fabric and support frame, including a support member, fabric, a base, and a supporting device. Fixing members are arranged on both sides of the fabric, and the fixing members are installed on the support member. The base and the support member are connected through a supporting device. The supporting device includes symmetrically arranged support arms that are opened outward at a certain angle. The support member is installed on the support arm, so that when the support member is opened, the fixing members can tighten the fabric.

[0006] Furthermore, it also includes an adapter, which includes a plug-in connector and a rotating shaft device, and the adapter is used to connect the support arm and the support member.

[0007] Furthermore, a receiving groove is provided on the support arm, and a mounting hole for mounting a rotating shaft device of the adapter is provided in the receiving groove, so that the adapter can rotate in the receiving groove.

[0008] Furthermore, the support member is provided with an inserting groove, and when the inserting member of the adapter is inserted into the inserting groove, the support arm opens the support member, so that the fabric connected to the fixing member is opened and tightened.

[0009] Furthermore, when the adapter is rotated under pressure in the accommodating groove, the distance between the two supporting members can be expanded, thereby tightening the fabric.

[0010] Furthermore, a telescopic device is provided between the base and the supporting device, and the overall length of the telescopic device can be adjusted by an adjusting rod, thereby adjusting the height of the seat.

[0011] Furthermore, the support member is provided with a backrest connecting member at the backrest position, and two ends of the backrest connecting member are respectively fixedly connected to the two support members.

[0012] Furthermore, the support member is overall L-shaped, and is provided with multiple bends to increase overall longitudinal elasticity.

[0013] Furthermore, the fixing member can gather the excess fabric, so that when the fixing member is installed on the supporting member, the fabric can be tightened by the normally opened supporting member.

[0014] Furthermore, the ends of the fabric and the support member are arranged as curling structures.

[0015] The beneficial effects of the present invention are:

[0016] 1. Use fabrics that can bear enough weight to replace conventional hard seat seats and backrests to reduce transportation space and weight. Fix the edges of the fabric on both sides to the fixings, and use a detachable fixed connection between the fixings and the support parts; spread the support parts and install the two support parts on the support device of the base so that the fabric between the two support parts is tightened and can bear enough weight to meet the customer's seat needs.

[0017] 2. The support device is provided with multiple support arms, and the support arms are connected to the support members through adapters. The support arms are symmetrically arranged, that is, the number of support arms connected to each support member is equal and the positions are symmetrical; there is a certain angle between the support arms, the adapters, the support members and the fabric, which can convert part of the bearing force into tension of the fabric, so as to improve the user's seat comfort.

[0018] 3. The disassembly and assembly of the supporting parts, base, supporting device and other parts are convenient and simple to operate. Compared with the hard chair surface and backrest, the production process is reduced, which saves manpower and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0027] Conventional hard chair cushions or backrests often have soft materials added to the outer surface to optimize the user experience. During transportation, the outer surface material needs to be protected from damage and stains, so a larger transportation space is required to ensure that the product is intact and usable when it reaches the user, which places high requirements on transportation. In the present invention, a flexible, foldable, lightweight fabric 2 can be used to replace the hard seat surface of a conventional chair. The transportation space occupied by the foldable flexible fabric 2 is greatly reduced, and the weight of the fabric 2 is much smaller than that of the hard seat surface, reducing the transportation weight. During transportation, the folded fabric 2 only needs to occupy a very small space, and the space occupied by the protective device to ensure that it is not stained or damaged is also very small. The use of a flexible, foldable, lightweight fabric 2 can increase the single transportation volume and reduce the total transportation cost.

[0028] Fabric 2 can be made of nylon transparent mesh, the mesh of the transparent mesh should not be too large, it is breathable and does not squeeze people; Fabric 2 can withstand sufficient load-bearing capacity to meet the normal needs of the seat.

[0029] The present invention uses fabric 2 to replace conventional hard chair seats and backrests, which not only facilitates the transportation of goods and the disassembly and assembly of consumers, but also greatly reduces the production processes and production materials in the production stage, further saves manpower and material costs, and can greatly save the production cost of seats.

[0030] The present invention provides a chair with self-installed fabric and support frame, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The main components include a support member 1, a fabric 2, a base 3, and a support device 4. The two sides of the fabric 2 are provided with fixing members 21, and the fixing members 21 are used to determine the width of the fabric 2 in a normal state, that is, the width of the fabric 2 when no force is applied. The fixing members 21 can be installed on the support member 1, and the fixing members 21 on one side of the fabric 2 can be installed on one support member 1, and the fixing members 21 on the other side of the fabric 2 can be installed on another support member 1, so that the two support members 1 can fully open the fabric 2. The base 3 is connected to the bottom of the support device 4, and the upper part of the support device 4 is provided with a support arm, and the support arm is connected to the support member 1. The support arms can be symmetrically arranged, that is, the same number of support arms with symmetrical positions are extended to both sides with the support device 4 as the center. The number of support arms arranged in the embodiment of the present invention is two pairs, four support arms, and two support arms on one side, which can stably support the support member 1 and ensure the stable connection of the support member 1. A support member 1 is installed on both sides of the support device 4, so that the two support members 1 can be opened to open and tighten the fabric 2.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , an adapter 6 can be set between the support arm and the support member 1 to convert part of the force direction of the support member 1. The adapter 6 includes a plug-in connector 61 and a rotating shaft device 62. The support arm of the support device 4 can form a certain angle with the plane where the support member 1 is located. At the connection position between the support member 1 and the support arm, a plug-in slot 11 can be set on the support member 1, and a receiving slot 41 can be opened on the support arm. The receiving slot 41 is provided with a mounting hole for installing the rotating shaft device 62, so that the adapter 6 can rotate in the receiving slot 41. When the plug-in connector 61 is inserted into the plug-in slot 11, the support member 1 and the support arm are connected together through the adapter 6. There is a certain angle between the adapter 6 and the plane where the two support members 1 are located. Within the allowable range of the receiving slot 41, the adapter 6 can rotate under force.

[0032] When the fabric 2 in the middle of the support 1 is stressed, the fabric 2 will generate an inward pulling force on the support 1. At this time, the support 1 will apply an upward rotation force to the adapter 6, causing the adapter to rotate upward, and the distance between the two support members 1 will become smaller; when the fabric 2 is stressed and generates an inward pulling force on the support 1, the support 1 itself will also be subjected to downward pressure, and the support 1 will generate downward pressure on the support arm. At this time, the support 1 will generate a downward pressure on the adapter 6. When the adapter 6 is subjected to pressure, it will rotate along the shaft device 62, slightly stretching the distance between the supports 1, so that the tension of the fabric 2 becomes greater. The pressure on the support 1 is greater than the pulling force of the fabric 2 on the support 1, so the adapter 6 will eventually convert the pressure of the support 1 into horizontal reverse tension, deepening the tension of the fabric 2, and will not cause the fabric 2 to sag too deeply, affecting the user's comfort experience. It is understandable that the angles between the support arm and the plane where the support member 1 is located, and between the adapter 6 and the plane where the support member 1 is located can be adjusted according to actual conditions as long as they can meet actual functional requirements.

[0033] After the receiving groove 41 and the adapter 6 are connected through the rotating shaft device 62 and the mounting hole, a screw hole can be provided on the side where the adapter 6 and the receiving groove 41 are in contact, and a bolt is provided on the receiving groove 41 accordingly, so that the rotation angle of the adapter 6 around the rotating shaft device 62 is limited by the length of the bolt, so that the connection between the adapter 6 and the support arm is stable. It can be understood that there are many ways to limit the rotation angle of the adapter 6, as long as the function is met.

[0034] See also Figure 1 , Figure 2A telescopic device can be set between the base 3 and the support device 4, and an adjusting rod is set to control the telescopic length of the telescopic device. The height of the load-bearing surface of the seat can be adjusted by adjusting the overall length of the telescopic device to suit different user groups or usage scenarios. The base 3 can be provided with multiple brackets to maintain a stable support state with the ground. In the embodiment of the utility model, five brackets are used to form a stable support structure with the ground to achieve multi-directional support. When one of the brackets is suspended in the air, the other four brackets can still ensure the support stability of the base 3. After the telescopic device is installed in the central part of the support device 4, an anti-collision device can also be set at the upper end of the support device 4 to avoid safety hazards to objects and users on the seat when the force of the telescopic device exceeds the capacity range.

[0035] As an implementation method, the surface of the support device 4 corresponding to one side of the fabric can be structurally optimized, so that when the fabric is cut, in the absence of a replacement, the upper surface of the support device 4 can be used directly or indirectly to meet the functional requirements of the seat. As another implementation method, an elastic support belt can be set between the two symmetrical adapters 6, which can tighten the distance between the two support members 1 to facilitate the elastic retraction of the fabric 2, and further can bear a certain gravity to prevent the fabric 2 from being damaged due to an accident and the seat being unusable. The elastic support belt can temporarily serve as a cushion and continue to perform the function of the fabric 2.

[0036] See also Figure 1 , Figure 2 The overall structure of the support member 1 can be set to an "L" shape, the horizontal part can be used as a seat cushion, and the vertical part can be used as a backrest. The bending part of the support member 1 can be set with multiple bends, such as Figure 1 or Figure 2 As shown in the support frame 1 in FIG. Arranging multiple bends on the support member 1 can improve the elasticity of a single support member 1 in the longitudinal direction and improve the user experience. At the same time, multiple bends can also maintain the hardness of a single support member 1 in the transverse direction, ensuring that the fabric 2 can be fully opened and tightened. A backrest connector 5 can be arranged between the two support members 1 at the backrest, and the two ends of the backrest connector 5 are respectively fixed to a support member 1, so that at the backrest, the spacing of the support members 1 can be determined by the backrest connector 5 and will not change.

[0037] There are many implementation methods between the fixing part 21 and the fabric 2. As one implementation method, the width of the fabric 2 can be preset, and the fixing part 21 can be directly fixedly connected to the fabric 2. At this time, the fixing part 21 does not have the effect of gathering the excess fabric 2, that is, the fixing part 2 and the fabric 2 are fixedly arranged, and the length of the fixing part 21 can be set to be an interconnection of short-segment structures, so that it can adapt to the bent support 1, and the fixing part 21 is fixed to the support 1 by screws, or a snap groove is opened on the support 1, and the fixing part 21 designed to match the groove is snapped into the groove. As a second implementation method, the fixing part 21 can be set to a scroll type, so that the fixing part 21 can gather the excess fabric 2, and then the fixing part 21 is fixed to the support 1 to ensure that the fabric 2 is not released when under pressure; wherein the fixing part 21 needs to adapt to the support 1 in the bending area when it is fixed to the support 1, and the shape of the fixing part 21 can be changed accordingly.

[0038] The ends of the support member 1 and the ends of the fabric 2 can be set as a curling structure 22. The ends of the support member 1 can be set as an inwardly curling structure 22 in cooperation with the fixing member 21 of the fabric 2, so that the fabric 2 is rolled inward at both ends of the support member 1, protecting the end structure of the fabric 2 from damage. A support shaft can also be added to the middle part of the curling structure 22 to stabilize the bearing tension of the fabric 2.
