Description

Technical Field

[0001] This utility model relates to the field of furniture, and more particularly to a removable chair with concealed fastening. Background Technology

[0002] In terms of structure, a chair typically consists of two main components: the seat and the backrest.

[0003] To reduce transportation costs and storage space, these chairs are typically supplied in a disassembled state, allowing users to assemble them themselves at the point of use. In existing technology, the seat and backrest are generally connected detachably using threaded fasteners. Specifically, screws are installed on the seat, passing through the seat structure and connecting to a corresponding position at the bottom of the backrest, thus achieving a simple and reliable fixation between the two.

[0004] To further enhance the appearance and decorative effect, the seats of these chairs are often covered with a decorative sleeve. However, in existing implementations, the screws used to connect the seat and backrest often pass directly through the decorative sleeve and are exposed to the outside view, making the screw heads or nuts clearly visible. This structural layout, to some extent, detracts from the overall appearance of the decorative sleeve, affecting the chair's aesthetics and sense of luxury, and therefore requires improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a chair that is easy to assemble and disassemble between the seat and backrest and has a better overall appearance.

[0006] A concealed fastening detachable chair includes a seat and a backrest. The seat is covered with a decorative cover, and a fastening screw passes through the seat and is detachably connected to the bottom of the backrest. The fastening screw is concealed in the decorative cover. The decorative cover has an openable sealing member corresponding to the position of the fastening screw. The sealing member is used to make the decorative cover form a clearance opening when it is opened, providing a tool with the necessary clearance to tighten the fastening screw.

[0007] Preferably, the sealing component is located below the seat.

[0008] Preferably, the sealing component is located at the rear side of the chair seat.

[0009] Preferably, the bottom surface of the chair seat is provided with an upwardly recessed operating groove that communicates with the rear side of the chair seat for the operating tool to tighten the fastening screw, and the screw head of the fastening screw is located in the operating groove.

[0010] Preferably, the sealing component is a zipper or a snap fastener.

[0011] Preferably, the zipper or snap fastener is the same color as the decorative sleeve.

[0012] Preferably, the bottom of the backrest is embedded with a nut for engaging with the fastening screw.

[0013] Preferably, the nut is made of high-strength metal.

[0014] Preferably, the decorative sleeve is made of an elastic material.

[0015] In summary, this utility model has the following beneficial effects: 1. This utility model, by hiding the fastening screws in the decorative sleeve, compared with the prior art where the fastening screws directly pass through the decorative sleeve and are exposed to the external vision, makes the overall appearance of the chair better and more aesthetically pleasing. At the same time, when the sealing part is opened, it provides the necessary clearance for operating tools (such as bolt wrenches) to tighten the fastening screws, ensuring that the fastening screws can easily detach and install the seat and backrest.

[0016] 2: This utility model, by placing the sealing component on the rear side of the chair seat, fully considers the user's operating comfort. It not only provides a wide field of vision and ample operating space, but also helps to maintain a natural operating posture, thus making it easier and faster to tighten the screws.

[0017] 3: This utility model features an upwardly recessed operating groove on the bottom surface of the chair seat. The screw head of the fastening screw is located in the operating groove, which is connected to the rear side of the chair seat, allowing the operating tool to be inserted and tightened. Generally, after opening the sealing component, it is necessary to pull the surrounding material to both sides to make the clearance sufficiently large, thereby facilitating the insertion and tightening of the operating tool. The existence of the operating groove itself provides a certain space for the operating tool to be inserted. Therefore, after opening the sealing component, it is permissible to appropriately reduce the pulling of the surrounding material, avoiding obvious and easily noticeable collapse and deformation of the decorative sleeve at the sealing component.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example:

[0021] A type of concealed, fastened, disassembled chair, such as Figure 1-3 As shown, the chair includes a seat 1 and a backrest 2. The seat 1 is covered with a decorative sleeve 3, and chair legs 4 are connected to the bottom of the seat 1. The seat 1 is provided with fastening screws 5 that pass through it and are detachably connected to the bottom of the backrest 2. It is worth noting that in this embodiment, the fastening screws 5 are hidden in the decorative sleeve 3. The decorative sleeve 3 is provided with an openable sealing component 31 corresponding to the position of the fastening screws 5. The sealing component 31 is a zipper. Of course, the zipper should be as small as possible, and it can even be made so that only the zipper head is exposed and the exposed part of the zipper head is extremely small, that is, the zipper is basically invisible or will not be noticed. Of course, in other embodiments, the sealing component 31 can also be a snap fastener.

[0022] The fastening screw 5 is hidden in the decorative sleeve 3, which is better than the prior art where the fastening screw directly passes through the decorative sleeve and is exposed to the external vision. This makes the overall appearance of the chair better and more aesthetically pleasing. At the same time, when the sealing part 31 is opened, the decorative sleeve 3 can form a clearance 32 for operating tools (such as bolt wrenches) to tighten the fastening screw 5, so as to ensure that the fastening screw 5 can easily detach and install the seat 1 and the backrest 2.

[0023] In this embodiment, the sealing component 31 is located below the seat 1, and its position design allows the sealing component 31 to be well hidden under the seat 1. When the sealing component 31 is opened, it faces vertically towards the fastening screw 5, ensuring that the operating tool can reach the fastening screw 5.

[0024] In another embodiment, such as Figure 4-5 As shown, the sealing component 31 is located at the rear of the seat 1. Its position is designed with user comfort in mind, providing not only a wide field of vision and ample operating space, but also helping to maintain a natural operating posture, thus making it easier and faster to tighten the fastening screw 5. When the sealing component 31 is opened, it faces the fastening screw 5 horizontally.

[0025] The bottom surface of the seat 1 has an upwardly recessed operating groove 11. The screw head of the fastening screw 5 is located in the operating groove 11. This groove is connected to the rear side of the seat, allowing the operating tool to be inserted and tightened. Generally, after opening the sealing component 31, it is necessary to appropriately pull the surrounding material to both sides (in the attached diagram, both sides refer to the top and bottom sides) to make the clearance opening 32 sufficiently large, thereby facilitating the insertion and tightening of the operating tool. The existence of the operating groove 11 itself provides a certain space for the operating tool to be inserted. Therefore, after opening the sealing component 31, it is permissible to appropriately reduce the pulling of the surrounding material, avoiding obvious and easily noticeable collapse and deformation of the decorative sleeve 3 at the sealing component 31. Of course, it should be noted that the depth of the operating groove 11 should be reasonable, meeting the insertion requirements of the operating tool without affecting the structural strength of the seat 1 due to excessive depth.

[0026] In this embodiment, the zipper or snap fastener is the same color as the decorative sleeve 3, adopting a design that matches the color scheme of the decorative sleeve 3, making the overall appearance more harmonious and unified when the sealing component 31 is closed.

[0027] In this embodiment, a nut is embedded in the bottom of the backrest 2 for connecting with the fastening screw 5. The nut is made of high-strength metal, such as 45# carbon steel, which can withstand greater tensile and compressive forces after engaging with the fastening screw 5, ensuring the stability of the connection between the backrest 2 and the seat 1.

[0028] In this embodiment, the decorative sleeve 3 is made of elastic material and can fit tightly against the surface of the seat 1.

[0029] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
