Abstract
Description
Technical Field
[0001] This utility model relates to a type of furniture, and more particularly to a chair seat and a chair. Background Technology
[0002] To improve comfort, some chairs have seat cushions, which consist of an elastic inner core and an outer cover. Currently, these cushions are directly attached to the seat frame during manufacturing and cannot be separated. However, after prolonged use, the cushions become dirty and require cleaning and maintenance. Because the cushions cannot be removed, cleaning them is difficult. Therefore, there is an urgent need for a chair seat design that allows for convenient cushion maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a seat and chair to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A chair seat includes: a seat cushion having connecting structures on at least two sides, the connecting structures including connecting pieces and snap-fit members, the connecting pieces being connected to the bottom side of the seat cushion and the snap-fit members being connected to the connecting pieces; and a seat shell located on the bottom side of the seat cushion, the bottom side of the seat shell having connecting grooves corresponding to the positions of the multiple connecting structures, and the multiple snap-fit members being detachably connected to the multiple connecting grooves.
[0006] This technical solution has at least the following beneficial effects: the seat shell is used to connect to the seat frame of the external device, thereby assembling the entire seat; the seat cushion is used to provide elastic support and improve the user experience; and at least two sides of the seat cushion are provided with structures that connect to the seat shell. When connecting the connecting structure to the seat shell, the connecting piece is passed downwards through the outside of the seat shell, and the snap-fit on the connecting piece is connected to the connecting groove, thereby realizing the mutual connection and fixation of the seat cushion and the seat shell. When the seat cushion needs to be removed, the snap-fit can be disengaged from the connecting groove. In this way, the seat cushion can be quickly disassembled from the seat shell, which is convenient for maintenance or replacement of the seat cushion during use, and reduces the difficulty of assembling the seat cushion and the seat shell during production, thereby improving production efficiency.
[0007] As a further improvement to the above technical solution, the snap-fit component includes a connecting section and a snap-fit section that are interconnected. The connecting section is connected to the connecting piece, and the snap-fit section extends in a direction away from the connecting section and is inserted into the connecting groove. During production, the connecting section is connected to the connecting piece, thereby assembling the snap-fit component and the connecting piece into a single unit. When it is necessary to connect the seat cushion to the seat housing, the connecting piece is moved downwards past the outside of the seat housing, and the snap-fit section is inserted upwards into the connecting groove, thereby connecting and fixing the seat cushion and the seat housing together. When it is necessary to separate the seat cushion from the seat housing, the snap-fit section is simply removed from the connecting groove.
[0008] As a further improvement to the above technical solution, the snap-fit segment is connected to multiple snap-fit blocks, and the sidewall of the connecting groove is provided with snap-fit slots corresponding to the positions of the multiple snap-fit blocks. The multiple snap-fit blocks are snapped into the multiple snap-fit slots respectively. When the snap-fit segment is inserted into the connecting groove, the multiple snap-fit blocks on the snap-fit segment are snapped into the multiple snap-fit slots on the sidewall of the connecting groove, which can improve the stability of the snap-fit segment's positioning in the connecting groove and prevent the snap-fit segment from easily coming loose from the connecting groove.
[0009] As a further improvement to the above technical solution, a mounting groove is provided on the bottom side of the housing, and a connecting groove is formed at the bottom of the mounting groove, with the connecting section housed within the mounting groove. After the snap-fit section is inserted into the connecting groove, the connecting section enters the mounting groove, thus making the overall connection structure more compact, reducing the protrusion of the connecting section on the bottom side of the housing, and improving the overall appearance.
[0010] As a further improvement to the above technical solution, a stop block is provided on one side of the groove of the connecting groove on the housing, and the stop block presses the connecting section into the mounting groove. After the snap-fit section is inserted into the connecting groove, the side of the connecting section extends beyond the stop block and enters into the mounting groove. At this time, the stop block can press the connecting section into the mounting groove, further preventing the connecting section from coming out of the mounting groove and improving the stability of the connecting section installed in the mounting groove.
[0011] As a further improvement to the above technical solution, the snap-fit component is made of an elastic material. Because the snap-fit component itself can elastically deform, when the side of the connecting segment passes over multiple stops, the connecting segment can elastically deform to avoid the positions of the stops, thereby allowing the connecting segment to be better installed into the mounting slot and improving the ease of installing the snap-fit component.
[0012] As a further improvement to the above technical solution, the connecting structures are respectively provided on the two opposite sides of the seat cushion. When the seat cushion is connected to the seat shell, the connecting pieces on both sides of the seat cushion pass downwards through the two sides of the seat shell, and the two snap-fit pieces are respectively connected to the connecting grooves, so that the seat cushion and the seat shell are connected and fixed on the opposite sides, improving the stability of the connection between the two.
[0013] As a further improvement to the above technical solution, a limiting groove is provided on the bottom side of the seat cushion, and the top side of the seat shell abuts against the bottom of the limiting groove. The bottom side of the seat cushion arches upward to form a limiting groove that accommodates and surrounds the seat shell. When the seat cushion and the seat shell are connected to each other, the top side of the seat shell abuts against the bottom of the limiting groove, which allows for quick alignment and connection of the seat shell, improving the convenience of mutual assembly and connection.
[0014] As a further improvement to the above technical solution, the seat cushion includes an outer cover and an inner core. The outer cover wraps around the outer side of the inner core, and a zipper is provided on the bottom side of the outer cover to open or close the interior of the outer cover. At least two connecting pieces are connected to the bottom side of the outer cover. After separating the seat cushion from the seat shell, the zipper on the bottom side of the outer cover can be opened to expose the space inside the outer cover, allowing the inner core to be removed. At this time, the outer cover and the inner core can be maintained and repaired separately. After completion, the inner core is reinstalled into the outer cover, and then the zipper is closed.
[0015] A chair includes a seat frame, a seat as described above, and a seat shell connected to the top side of the seat frame.
[0016] The technical solution has at least the following beneficial effects: the seat frame can raise the height of the chair seat and support and fix the chair seat. When the chair seat needs maintenance, the seat cushion can be quickly removed from the seat shell, which makes it convenient to maintain or replace the seat cushion during use. It also reduces the difficulty of assembling the seat cushion and seat shell together during production and improves production efficiency. Attached Figure Description

[0028] Reference Figure 1 , Figure 2 and Figure 3 A chair seat includes a seat cushion 100 and a seat shell 200. The seat cushion 100 has connecting structures on at least two sides. Each connecting structure includes a connecting piece 110 and a snap-fit member 120. The connecting piece 110 is connected to the bottom side of the seat cushion 100, and the snap-fit member 120 is connected to the connecting piece 110. The seat shell 200 is located on the bottom side of the seat cushion 100. The bottom side of the seat shell 200 has connecting grooves 210 corresponding to the positions of the multiple connecting structures. The multiple snap-fit members 120 are detachably connected to the multiple connecting grooves 210.
[0029] As described above, the seat shell 200 is used to connect to the seat frame of the external device, thereby assembling the entire seat. The seat cushion 100 is used to provide elastic support and improve the user experience. At least two sides of the seat cushion 100 are provided with structures that connect to the seat shell 200. When connecting the connecting structure to the seat shell 200, the connecting piece 110 is passed downwards through the outside of the seat shell 200, and the snap-fit piece 120 on the connecting piece 110 is connected to the connecting groove 210, thereby realizing the mutual connection and fixation between the seat cushion 100 and the seat shell 200. When it is necessary to remove the seat cushion 100, the snap-fit piece 120 can be disengaged from the connecting groove 210. In this way, the seat cushion 100 can be quickly disassembled from the seat shell 200, which is convenient for maintenance or replacement of the seat cushion 100 during use, and reduces the difficulty of assembling the seat cushion 100 and the seat shell 200 during production, thereby improving production efficiency.
[0030] The snap-fit component 120 is used to connect with the housing 200. During production, the snap-fit component 120 needs to be connected and fixed to the connecting piece 110. For example, the snap-fit component 120 is connected to the connecting piece 110 by machining and using steel nails. Naturally, the snap-fit component 120 has a part that can be detached from the connecting groove 210. Therefore, in this embodiment, as... Figure 4 As shown, the snap-fit component 120 includes a connecting section 121 and a snap-fit section 122 connected to each other. The connecting section 121 is connected to the connecting piece 110, and the snap-fit section 122 extends in a direction away from the connecting section 121 and is inserted into the connecting groove 210. During production, the connecting section 121 is connected to the connecting piece 110 by machining and nailing, thereby assembling the snap-fit component 120 and the connecting piece 110 into a single unit. When it is necessary to connect the seat cushion 100 to the seat shell 200, the connecting piece 110 is moved downwards past the outside of the seat shell 200, and the snap-fit section 122 is inserted upwards into the connecting groove 210, thereby connecting and fixing the seat cushion 100 and the seat shell 200 together. When it is necessary to separate the seat cushion 100 from the seat shell 200, the snap-fit section 122 is simply removed from the connecting groove 210.
[0031] In practical applications, in order to enhance the elastic deformation capability of the connecting segment 121, multiple notches can be provided on the connecting segment 121.
[0032] In the above embodiment, when the snap-fit segment 122 is inserted into the connecting slot 210, as follows: Figure 5As shown, the snap-fit segment 122 can be fixed in the connecting groove 210 by friction between its surface and the inside of the groove after insertion. To further prevent the snap-fit segment 122 from detaching directly from the groove, in this embodiment, multiple snap-fit blocks 123 are connected to the snap-fit segment 122. The sidewall of the connecting groove 210 is provided with slots 211 corresponding to the positions of the snap-fit blocks 123, and the snap-fit blocks 123 are respectively snapped into the slots 211. When the snap-fit segment 122 is inserted into the connecting groove 210, the multiple snap-fit blocks 123 on the snap-fit segment 122 are respectively snapped into the slots 211 on the sidewall of the connecting groove 210. This improves the stability of the snap-fit segment 122's positioning within the connecting groove 210 and prevents it from easily detaching. In practical applications, in order to facilitate the insertion of the card block 123 into the card slot 211, the shape of the card block 123 can be designed as a triangle, and the triangular inclined surface on the card block 123 can be used as a guide to make the card block 123 more smoothly inserted into the card slot 211.
[0033] When there are two connecting structures, there are several ways to fix the snap-fit segment 122 to the connecting groove 210. For example, neither snap-fit segment 122 has a snap-fit block 123, and it is mainly fixed in the connecting groove 210 by friction. Alternatively, each snap-fit segment 122 has a snap-fit block 123, and it is mainly fixed in the connecting groove 211 on the side wall of the connecting groove 210 by snap-fit block 123. Alternatively, one snap-fit segment 122 does not have a snap-fit block 123, and it is mainly fixed in the connecting groove 210 by friction. The other snap-fit segment 122 has a snap-fit block 123, and it is mainly fixed in the connecting groove 210 by the cooperation of the snap-fit block 123 and the snap-fit block 123.
[0034] After the snap-fit segment 122 is inserted into the connecting groove 210, the connecting segment 121 may protrude downwards from the bottom side of the base shell. To improve the appearance of the connection structure, in this embodiment, the bottom side of the base shell 200 is provided with a mounting groove 220, and the connecting groove 210 is formed at the bottom of the mounting groove 220. The connecting segment 121 is accommodated within the mounting groove 220. After the snap-fit segment 122 is inserted into the connecting groove 210, the connecting segment 121 enters the mounting groove 220. This makes the overall connection structure more compact, reduces the protrusion of the connecting segment 121 on the bottom side of the base shell 200, and improves the overall appearance.
[0035] After the connecting segment 121 is fitted into the mounting groove 220, a structure can be provided to limit the connection segment 121, so that the connection segment 121 remains within the mounting groove 220. Specifically, the housing 200 is provided with a stop 230 on one side of the groove opening of the connecting groove 210. The stop 230 presses the connecting segment 121 against the mounting groove 220. After the snap-fit segment 122 is inserted into the connecting groove 210, the side of the connecting segment 121 extends beyond the stop 230 and enters the mounting groove 220. At this time, the stop 230 can press the connecting segment 121 against the mounting groove 220, further preventing the connecting segment 121 from coming out of the mounting groove 220 and improving the stability of the connecting segment 121 installed in the mounting groove 220. In practical applications, there can be multiple stops 230. Multiple stops 230 are spaced apart along the length of the connecting groove 210, so that the connecting section 121 is pressed against the mounting groove 220 by the multiple stops 230.
[0036] Furthermore, the snap-fit component 120 is made of an elastic material, such as rubber or plastic. Because the snap-fit component 120 itself is elastically deformable, when the side of the connecting segment 121 passes over the multiple stops 230, the connecting segment 121 can be elastically deformed to avoid the positions of the multiple stops 230, thereby allowing the connecting segment 121 to be better inserted into the mounting groove 220, improving the ease of installing the snap-fit component 120.
[0037] The connecting structures can be located on multiple sides of the seat cushion 100. For example, there can be four connecting structures, each located on one of the four sides of the base pad. This establishes a connection and positioning between the four sides of the seat cushion 100 and the four sides of the seat shell 200. Alternatively, the connection and positioning can be established between two opposite sides of the seat cushion 100 and the seat shell 200. Specifically, the connecting structures are provided on the opposite sides of the seat cushion 100. When the seat cushion 100 is connected to the seat shell 200, the connecting pieces 110 on both sides of the seat cushion 100 pass downwards through both sides of the seat shell 200, and the two snap-fit pieces 120 are respectively engaged and connected to the connecting grooves 210, so that the seat cushion 100 and the seat shell 200 are connected and fixed on opposite sides, improving the stability of the connection.
[0038] When connecting the seat cushion 100 and the seat shell 200, a mutually limiting structure can be provided between them to facilitate alignment. Specifically, a limiting groove 130 is provided on the bottom side of the seat cushion 100, and the top side of the seat shell 200 abuts against the bottom of the limiting groove 130. The bottom side of the seat cushion 100 arches upward to form the limiting groove 130 that accommodates and surrounds the seat shell 200. When connecting the seat cushion 100 and the seat shell 200, the top side of the seat shell 200 abuts against the bottom of the limiting groove 130, allowing for quick alignment and connection of the seat shell 200, thus improving the convenience of assembly and connection. In practical applications, the side wall of the limiting groove 130 can abut against the outer side of the top of the seat shell 200, so that the top side of the seat cushion 100 wraps around the top of the bottom shell. Alternatively, the side wall of the limiting groove 130 can be inclined in a direction away from its center. In this case, the limiting groove 130 forms a space that is smaller at the top and larger at the bottom, which can facilitate quick connection and alignment when the bottom shell and the seat cushion 100 are matched.
[0039] The seat cushion 100 can be a single, integrated structural component, or it can be a separate structure that can be disassembled internally and externally. Specifically, the seat cushion 100 includes an outer cover and an inner core. The outer cover wraps around the outer core, and a zipper 140 is provided on the bottom side of the outer cover to open or close the interior of the outer cover. At least two connecting pieces 110 are connected to the bottom side of the outer cover. For example, the inner core can be a sponge, rubber, or other elastically deformable material. After separating the seat cushion 100 from the seat shell 200, the zipper 140 on the bottom side of the outer cover can be opened to expose the interior space of the outer cover, allowing the inner core to be removed. At this time, the outer cover and the inner core can be maintained separately. After completion, the inner core is reinstalled into the outer cover, and then the zipper 140 is closed.
[0040] A chair includes a seat frame and a seat as described above, with the seat shell 200 connected to the top side of the seat frame. Naturally, depending on usage needs, armrests, a backrest, etc., can also be provided on the seat frame to enrich the overall functionality.
[0041] As can be seen from the above, the seat frame can raise the height of the chair seat and support and fix the chair seat. When the chair seat needs to be maintained, the seat cushion 100 can be quickly removed from the seat shell 200, which makes it convenient to maintain or replace the seat cushion 100 during use, and reduces the difficulty of assembling the seat cushion 100 and the seat shell 200 during production, thereby improving production efficiency.
[0042] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
