Detailed Description

In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

The specific embodiments of the present application are as follows:

example 1: as shown in fig. 1-12, the present application provides a seat comprising an outer cover 1, a base, a seat 17, a back 2, and a connecting bracket. Wherein the cover 1 is sleeved outside the chair back 2, and the cover 1 can be separated from the chair back main body 2.

In this embodiment, the seat back 2 includes a plurality of assembly modules, and the seat back 2 is formed by mutually splicing and assembling the plurality of assembly modules. When in conveying, a plurality of assembly modules can be detached for stacking, so that the placing space is greatly saved, and the conveying and the transportation are convenient. When the assembly module is needed to be used, a plurality of assembly modules are only needed to be assembled, so that convenience is brought to a user, and a certain assembly achievement is brought.

Specifically, referring to fig. 4, 7 and 8, the plurality of assembly modules includes an upper back plate 3 and a lower back plate 4, wherein a first positioning groove 5 is disposed at a bottom end of the upper back plate 3, and a first positioning protrusion 6 matched with the first positioning groove 5 is disposed at a top end of the lower back plate 4. The upper backboard 3 and the lower backboard 4 can be spliced with each other so that the first positioning protrusion 6 is inserted into the first positioning groove 5. And the upper backboard 3 and the lower backboard 4 can be connected through screws after being in plug-in fit, so that the upper backboard 3 and the lower backboard 4 are kept relatively fixed. The upper backboard 3 and the lower backboard 4 are spliced with each other.

And preferably, as shown in fig. 7, in the present solution, the groove walls on both sides of the first positioning groove 5 extend obliquely outwards along the direction from the groove bottom to the groove opening, and the groove walls on both sides of the first positioning groove 5 are arc surfaces. Since both side groove walls of the first positioning groove 5 extend outwards obliquely along the groove bottom to groove opening direction, in the plugging process, a certain guiding effect can be achieved through the groove walls of the first positioning groove 5, and even if the first positioning groove 5 is not completely aligned with the first positioning protrusion 6 in the plugging process, both side groove walls of the first positioning groove 5 can also slide to the groove bottom for plugging and matching. And because both side cell walls of the first positioning groove 5 are arc-shaped surfaces, the guiding is more facilitated, and the appearance is more attractive.

Meanwhile, in order to facilitate the connection of the upper backboard 3 and the lower backboard 4 through bolts after the plugging and matching. As shown in fig. 4, the first positioning boss 6 of the lower back plate 4 is provided with a mounting groove 7. As shown in fig. 7, the bottom of the first groove at the bottom end of the upper back plate 3 is provided with a mounting boss 8. When the first positioning protrusion 6 is inserted into the first positioning groove 5 for splicing and assembling, the mounting boss 8 is inserted into the mounting groove 7, and the upper backboard 3 and the lower backboard 4 can be kept relatively fixed through screw connection between the mounting boss 8 and the mounting groove 7. Since the screws are to be screwed, a place where the upper back plate 3 and the lower back plate 4 overlap is required. And when the first positioning bulge 6 is inserted into the first positioning groove 5, the installation boss 8 is inserted into the installation groove 7, so that the place where the screw is installed can not protrude out of the back plate, and the whole appearance is smoother.

It should be noted that, although in the present embodiment, the first positioning groove 5 is disposed at the bottom end of the upper back plate 3, and the first positioning protrusion 6 is disposed at the top end of the lower back plate 4. It is also possible to provide the first positioning groove 5 at the top end of the lower back plate 4 and the first positioning protrusion 6 at the bottom end of the upper back plate 3.

It should be noted that, although in the present embodiment, the mounting groove 7 is disposed on the first positioning protrusion 6 of the lower back plate 4, and the mounting boss 8 is disposed at the bottom of the first groove at the bottom end of the upper back plate 3. However, it is equally possible that the mounting groove 7 is provided at the groove bottom of the first groove at the bottom end of the upper back plate 3, and the mounting boss 8 is provided on the first positioning boss 6 of the lower back plate 4.

In addition, in this embodiment, the plurality of assembly modules further includes two side wings 9, as shown in fig. 5, where the two side wings 9 are respectively located at two sides of the bearing member 18 and extend obliquely outward toward the front end plate surface of the bearing member 18, and each side wing 9 is detachably connected to the bearing member 18. The waist is wrapped by the side wings 9 at the two sides, so that the user can sit more comfortably.

In this embodiment, the bearing member 18 is provided with the second positioning protrusion 10. And the side wall of the side wing 9 is provided with a second positioning groove 12. When the side wall of the side wing 9 and one side of the bearing piece 18 are jointed, the second positioning protrusion 10 is inserted into the second positioning groove 12, and the side wing 9 and one side of the bearing piece 18 are connected through screws.

Preferably, in this embodiment, the second positioning protrusion 10 is disposed on a side wall of the upper back plate 3 in the bearing member 18. And a third positioning protrusion 11 is provided on a side wall of the lower back plate 4. When the second positioning protrusion 10 is inserted into the second positioning groove 12, the third positioning protrusion 11 is also placed in the second positioning groove 12, and the groove wall of the second positioning groove 12 presses the third positioning protrusion 11 to be always clung to the second positioning protrusion 10. Because the second positioning protrusion 10 is arranged on the side wall of the upper back plate 3, the third positioning protrusion 11 is arranged on the side wall of the lower back plate 4, when the second positioning protrusion 10 is inserted into the second positioning groove 12, the groove wall of the second positioning groove 12 presses the third positioning protrusion 11 to be clung to the second positioning protrusion 10 all the time, and even if the screw connected between the upper back plate 3 and the lower back plate 4 is separated or lost, the upper back plate 3 and the lower back plate 4 cannot be separated.

But in order to facilitate the screw connection between the flanks 9 and the bearing piece 18. As shown in fig. 5 and 6, the side wall of the bearing member 18 is provided with a fourth positioning protrusion 13, and the side wall of the side wing 9 is provided with a third positioning groove 14. When the side wing 9 is placed on one side wall of the bearing member 18, the fourth positioning protrusion 13 is inserted into the third positioning groove 14, and the fourth positioning protrusion 13 is connected with the side wing 9 by a screw. Because the fourth positioning bulge 13 is connected with the side wing 9 through the screw, the positioning function is realized on the place where the screw is arranged, and the length requirement of the screw is reduced because the fourth positioning bulge 13 is positioned inside the side wing 9.

At the same time, the length of the flanks 9 is smaller than the length of the bearing elements 18. It is easy to understand that when the bearing member 18 is split into the upper back plate 3 and the lower back plate 4, which are stacked and packed in the box body, the stacked length of the upper back plate and the lower back plate is smaller than the length of the bearing member 18, and the length of the side wing 9 is also smaller than the length of the bearing member 18, so that the length required for loading the box body can be reduced.

In the scheme, the upper backboard 3, the lower backboard 4 and the two side wings 9 are all formed by plastic blow molding. Not only is it relatively lightweight for handling. And after plastic blow molding, the arrangement of grooves and protrusions on each part is also facilitated.

In this embodiment, the backrest 2 is connected to the seat 17 by a connecting bracket 15. Specifically, one end of the connecting bracket 17 is detachably connected with one assembly module in the chair back 2, and the other end of the connecting bracket 17 is detachably connected with the chair seat 17. As shown in fig. 4, the lower back plate 4 in this embodiment is provided with a caulking groove 16, and the connection bracket 15 is embedded in the caulking groove 16 and is connected with the bottom of the caulking groove 16 by a screw. The whole surface of the back of the chair is smooth and attractive by embedding the connecting bracket 15 in the caulking groove 16, and the connecting bracket 15 can be clamped in the caulking groove 16 during conveying, so that the occupied space is reduced.

And the seat 17 includes a seat cushion 19 and a contoured frame 20. The cushion 19 is made of a flexible material such as a sponge, and the mold-back frame 20 is made of a rigid material such as a metal, wherein the cushion 19 is placed on the mold-back frame 20. In this embodiment, the upper surface of the mold-back frame 20 is provided with a plurality of elastic first supporting members 22 arranged at intervals side by side, and the first supporting members 22 cooperate with the mold-back frame 20 to form a bottom support of the seat cushion 19. Meanwhile, a third connecting piece 30 is arranged below the first supporting piece 22 in the frame of the square frame 20 in the scheme. The base comprises a chassis mounted on the third connecting member 30, the bottom end of which is provided with feet and support wheels for supporting the seat 17 and back 2. The two sides of the chassis are provided with armrest frames, and the upper ends of the armrest frames are provided with armrest supporting surfaces. The other end of the connecting support frame 17 is connected with the chassis through a screw, so that the other end of the connecting support frame 17 is detachably connected with the seat 17.

In order to facilitate the disassembly and assembly of the cushion 19, as shown in fig. 9, a receiving cavity 21 is provided on the bottom end surface of the cushion 19, and a mold frame 20 is disposed in the receiving cavity 21. And the mold frame 20 can be taken out from the accommodating cavity 21, thereby being convenient for the disassembly and cleaning of the cushion 19. Since the cushion 19 is supported by the bottom of the cushion 19 formed by the first supporting member 22 on the loop frame 20, the cushion 19 does not need to be thick, the thickness of the cushion 19 can be reduced, the material of the cushion 19 can be reduced, and the manufacturing cost can be saved.

In this embodiment, the first supporting member 22 is a plurality of serpentine springs 22a, and the plurality of serpentine springs 22a are disposed side by side, and each of the serpentine springs 22a extends along the width direction of the mold frame 20. While both ends of each serpentine spring 22a are connected to the left and right side frames of the mold frame 20.

Specifically, both ends of the serpentine spring 22a are provided with first connecting pieces 23. As shown in fig. 12, the first connecting member 23 has a head end and a tail end in the longitudinal direction thereof, the tail end of the first connecting member 23 is connected to the serpentine spring 22a, and the head end of the first connecting member 23 is bent downward to form a first bent portion 24. A buckling groove 25 is formed between the first bending part 24 and the tail end of the first connecting piece 23. When the serpentine spring 22a is to be mounted on the mold frame 20, the serpentine spring 22a is only required to be transversely placed on the mold frame 20, and the left and right side frames of the mold frame 20 are respectively buckled in the buckling grooves 25 on the first connecting pieces 23 at two ends of the serpentine spring 22a to realize connection. Thereby removably connecting the serpentine spring 22a to the mold frame 20. Even if the installation of the serpentine springs 22a is facilitated, replacement of individual serpentine springs 22a is facilitated. And it is easy to understand that the square frame 20 is placed in the accommodating cavity 21 on the bottom end surface of the cushion 19, the upper end surfaces of the serpentine spring 22a and the first connecting piece 23 can prop against the cushion 19 to form limit, and there is no concern that the serpentine spring 22a can be separated from the square frame 20 in the sitting process. When the mold frame 20 is taken out from the accommodating cavity 21, the serpentine spring 22a can be directly taken down, and the disassembly is very convenient.

As a specific connection manner between the serpentine spring 22a and the first connecting member 23, as shown in fig. 12, in this embodiment, the tail end of the first connecting member 23 is provided with a jack 26, and the end of the serpentine spring 22a is inserted into the jack 26 to detachably connect the serpentine spring 22a with the first connecting member 23. This way of connection allows to save material even when the serpentine spring 22a is assembled with the first connection 23, but also when the serpentine spring 22a is replaced, the first connection 23 is preserved.

In this embodiment, a plurality of second supporting members 27 are disposed in the frame of the mold frame 20, the second supporting members 27 are disposed perpendicular to the serpentine springs 22a (i.e. the first supporting members 22), and two ends of the second supporting members 27 are respectively connected to adjacent serpentine springs 22 a. And preferably, as shown in fig. 10, both ends of the second support 27 are bent to one side of the second support 27 to form a second bent portion 28. The two ends of the second supporting piece 27 are bent to one side of the supporting piece to form a second bending part 28 to form a special-shaped piece, so that the structural strength of the second supporting piece 27 is improved, and the supporting area of the second supporting piece 27 at the bottom end of the serpentine spring 22a is increased.

And in order to allow the two ends of the second support 27 to be respectively connected to the adjacent serpentine springs 22 a. In this embodiment, the serpentine spring 22a is threaded with a second connector 29, and the second support 27 extends through the second connector 29 to be fixed relative to the serpentine spring 22 a. This structure facilitates both the assembly and fixation between the second support 27 and the serpentine spring 22a and the disassembly.

When a user sits on the seat cushion 19, the seat cushion 19 sags to give downward force to the serpentine spring 22a, and the serpentine spring 22a is also driven to have a tendency to shift outward while giving downward force to the serpentine spring 22 a. The existence of the second supporting piece 27 not only improves the structural supporting strength, but also avoids the phenomenon that a certain area or a plurality of snake-shaped springs 22a are stressed intensively to generate deflection in the using process, so that the snake-shaped springs 22a are stressed together under the action of the second supporting piece 27 in the human body using process, thereby preventing the snake-shaped springs 22a from generating larger intervals and keeping the intervals among the snake-shaped springs 22a uniform.

As shown in fig. 3 and 4, the back of the lower back plate 4 in this embodiment is provided with a storage groove 32. Specifically, the number of the storage grooves 32 is two, and the two storage grooves 32 are respectively arranged at two sides of the caulking groove 16. And each storage groove extends along the length direction of the lower backboard.

Meanwhile, as shown in fig. 9, the storage space 31 in which other seat components in the seat can be placed is provided below the first support member 22 in the frame of the mold frame 20 except for the third connecting member 30.

When the seat is disassembled, small parts such as the supporting legs, the supporting wheels and the like can be placed in the storage space 31 to realize overlapping stacking. And the handrail support plate and other parts can be placed in the storage groove 32 without being stacked separately, so that the boxing amount is reduced, the occupied space is reduced, and the conveying of the seat is facilitated.

Of course, in the case that the structural strength of the seat back 2 is ensured, and the width of each storage groove 32 can be provided with the parts to be provided, the number of the storage grooves 32 can be three, four, five, etc.

Based on the above-mentioned seat, as shown in fig. 14, the present embodiment also proposes a packaging method of the seat, which includes the following steps:

s1, preparing a box body for accommodating a seat;

s2, splitting the chair to separate the chair back, the chair seat and the connecting bracket from each other, and splitting the chair back into a plurality of assembly modules; the other seat components of the seat except the seat back, the seat base and the connecting bracket are divided into three parts, namely a first part component, a second part component and a third part component, wherein the first part component comprises a supporting wheel, the second part component comprises a handrail supporting surface, and the third part comprises a chassis, supporting legs and a headrest;

s3, placing the seat in the box body, and placing the first part of components in a storage space on the seat;

s4, stacking a plurality of assembly modules above the seat, and placing the second part of assemblies in storage grooves on the assembly modules;

s5, placing the connecting bracket and the third part assembly in the box body to remove the spare areas behind the seat and the chair back.

Specifically, step S4 is further divided into the following steps:

1. inserting two side wings into the box body at a certain included angle with the horizontal plane and stacking the two side wings above the seat, wherein a containing groove is formed between the two side wings;

2. and stacking the upper backboard and the lower backboard in the accommodating groove in sequence, and placing the second part of the assembly in a storage groove on the lower backboard.

According to the above-mentioned packing method, when packing the seat, the seat is first disassembled so that the seat back 2, the seat base 17 and the connection frame 15 are separated from each other, and at this time, the base is also disassembled to separate the seat components such as the chassis, the legs, the supporting wheels, the armrest supporting surface and the like and to divide the seat components into the first partial assembly, the second partial assembly and the third partial assembly. The first subassembly includes the supporting wheel, and the second subassembly includes the handrail bearing surface, and the third subassembly includes chassis, stabilizer blade and headrest.

Meanwhile, the chair back 2 is split into a plurality of assembly modules, namely the chair back 2 is split into the upper back plate 3, the lower back plate 4 and the two side wings 9, so that the upper back plate 3, the lower back plate 4 and the two side wings 9 are in an unconnected state. The seat 17 is then first placed in a pre-prepared box, as compared to the back 2. And in order to be able to place the first part-assembly in the storage space 31 on the seat 17. The first part of the components can be placed in the box body at the position where the storage space 31 on the seat 17 is located, and then the seat 17 is placed so that the first part of the components is covered in the storage space 31 to complete overlapping placement. The bottom end of the seat 17 may be swung up into the box and the first partial assembly placed into the storage space 31.

Then the two side wings 9 are inserted into the box body at a certain included angle with the horizontal plane and are piled above the seat 17 so that a containing groove is formed between the two side wings 9. The two side wings 9 and the horizontal surface form an included angle to be inserted into the box body, and the side wings 9 can be vertically placed into the box body or obliquely placed into the box body, so long as the side wings 9 can lean against the inner wall of the box body after being placed into the box body. The upper back plate 3 and the lower back plate 4 are then stacked in sequence in the receiving groove, in the course of which the second part-assembly is also placed in the storage groove 32 on the lower back plate 4. The second part of the assembly can be placed on the seat 17 and then covered into the lower back plate 4, in the same way as the seat 17. The lower back plate 4 may be placed in the box with its back facing upward, and then the second partial assembly may be placed in the storage tank 32.

And finally, placing the third part of the assembly in a spare area in the box body to finish packaging.

The packaged case and seat are shown in fig. 15.

In the packaging method, the first part of the components are placed in the storage space 31, and the second part of the components are placed in the storage tank 32. Because the area of the seat 17 is relatively small and square, it can be used to accommodate smaller components such as support wheels. The assembled module with the split chair back 2 has a relatively long lower back plate 4, and can be used for accommodating long components such as armrest supporting surfaces.

The different components are placed in the storage space 31 or the storage groove 32 correspondingly according to the shape and the size of the components. Namely, the overlapping stacking of the components is realized, the overall occupied space after stacking is reduced, and the supporting wheels placed in the storage space 31 in the stacking process cannot be exposed outside the storage space to influence the placement of the chair seat 17 or the chair back 2. Similarly, the handrail supporting surface in the storage groove 32 on the lower backboard 4 is not exposed outside the storage groove 32 to influence the placement of other assembly modules, so that the overall placement is more compact and smooth, the overall occupied space after stacking is further reduced, and the packaging of the seat is facilitated.

Meanwhile, the two side wings are arranged on the two sides of the upper backboard and the lower backboard, so that the overlapping of the side wings 9, the upper backboard 3 and the lower backboard 4 in the height direction is realized, the overall height after stacking is further reduced, and the height requirement of the box body is reduced. And two flanks 9 are arranged on two sides of the upper backboard 3 and the lower backboard 4, and two sides of each flank 9 are limited by the backboard and the inner wall of the box body, so that the flanks 9 and the upper backboard 3 and the lower backboard 4 can be prevented from shaking in the conveying process.

It should be noted that, under the condition of ensuring that the side wings 9 can be overlapped with the upper backboard 3 and the lower backboard 4 in the height direction, the upper backboard 3 and the lower backboard 4 can be stacked on the seat 17 in sequence, so that slots are formed between the two sides of the upper backboard 3 and the lower backboard 4 and the inner wall of the box body, and then the two side wings 9 are inserted into the two slots to realize overlapping placement and keep relatively stable. Or the lower back plate 4 is firstly placed on the seat 17, then the two side wings 9 are placed on the lower back plate 4, the two side wings 9 respectively lean against the inner walls of the two sides of the box body, and finally the upper back plate 3 is placed between the two side wings.

Example 2: as shown in fig. 13, this embodiment is different from the seat in embodiment 1 described above mainly in that in this embodiment, the seat 17 is integrally blow-molded, and the bottom end surface of the seat 17 is provided with a connection region 33 and a storage region 31a. The chassis for connecting the connecting bracket 15 is detachably provided on the connecting area 33 by means of screws. And the bottom surface of the seat 17 is recessed toward the interior of the seat at the storage area 31a to form a storage space 31 for other seat components in the seat.

The application and its embodiments have been described above by way of illustration and not limitation, and the application is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present application.
