Description

Technical Field

[0001] The present invention relates to the technical field of seats, and in particular to a functional integrated seat. Background Art

[0002] Among the existing seats, a Chinese utility model patent with publication number CN221903009U provides a sofa with a four-spring structure, including a sofa body, a sofa armrest including a solid wood support plate, two layers of super soft sponge are arranged on the solid wood support plate, and multiple mini pocket springs are arranged between the two layers of super soft sponge; the sofa back includes a sofa cushion and a sofa back frame body, multiple independent pocket springs A are arranged in the sofa cushion, and a bandage is arranged on the sofa back frame body; multiple independent pocket springs B and sponge are arranged in the sofa cushion, and a positioning line and multiple serpentine bow springs are arranged in the bottom frame of the sofa cushion, and the two ends of the serpentine bow spring are fixed to the bottom frame of the sofa cushion through bow spring buckles. The utility model sets springs of different structures for different parts of the same sofa according to the frequency of use and the pressure conditions, and different parts of the same sofa have different designs, which can not only reduce the production cost of the sofa, but also different parts are independent individuals, do not interfere with each other, have strong support and are durable.

[0003] In the above solution, the sofa adopts a wooden frame and laminates to achieve a frame structure, which is not only not environmentally friendly, but also contains glue components in the laminates, and the formaldehyde components cannot be removed.

[0004] Existing seats or sofas are made of wood, which are heavy and difficult to carry. In addition, due to their large size, the transportation cost after packing is high. The one-piece injection molding structure has limited structural strength, which affects the service life of the seat or sofa.

[0005] In addition, in order to improve the comfort of existing seats, some elastic components are installed on the frames of seats (sofas, leisure sofas, office chairs and car seats, etc.) to play the role of rebound and shock absorption. The hook connected to one end of the spring group is directly hung on the cross tube, and the gusset plate connected to the other end of the spring group is connected to the cross tube through a nail gun. During use, these two connection methods make the hook or gusset plate without a fixed part easily shake and rub against the cross tube to produce abnormal noise, which makes people feel uncomfortable. In addition, these two connection methods are unstable and easy to fall off during use.

[0006] In addition, in addition to single-person seats, side tables are usually provided for users to place items. The provision of side tables takes up space and increases configuration costs. Summary of the invention

The disassembly and assembly are very convenient, which can maximize the packaging utilization rate and reduce transportation costs.

[0055] At the same time, these parts are all formed by integrated welding of iron pipes, removing wood materials, protecting the environment, improving structural firmness, and removing formaldehyde. The seat frame has a large storage space, which can be used to place components such as backrests and armrests, further reducing the packaging volume, reducing transportation costs, increasing the amount of cabinets, and improving space utilization. In addition, a driving component is also set in the seat frame, which can fold down the backrest frame through the connecting component to realize the lying function of the seat; and a turntable component can also be installed in the storage space, through which the seat can be rotated to realize the rotation function of the seat.

[0056] Furthermore, a pair of rear butt-jointed iron sheets 15 are provided on the rear connecting iron pipe 12, a pair of front butt-jointed iron sheets 16 are provided on the front connecting iron pipe 13, and the driving component is a motor 17, and the two ends of the motor 17 are respectively extended between the pair of rear butt-jointed iron sheets 15 and the pair of front butt-jointed iron sheets 16 and are detachably connected to them; The connecting piece assembly includes a first fixed iron sheet 18, a second fixed iron sheet 19, a first rotating iron sheet 20, a second rotating iron sheet 21 and a transmission iron sheet 22, wherein the first fixed iron sheet 18 and the second fixed iron sheet 19 are fixedly installed on the inner upper part of the side iron frame 9, the first rotating iron sheet 20 is hinged on the first fixed iron sheet 18, and the two ends of the second rotating iron sheet 21 are respectively hinged on the first rotating iron sheet 20 and the side iron frame 9, and the front connecting iron pipe 13 is fixedly installed between the first rotating iron sheets 20 on both sides; One end of the transmission iron sheet 22 is fixedly connected to the first rotating iron sheet 20, the other end of the transmission iron sheet 22 is hinged to the lower outer side of the connecting iron sheet 14, the second fixed iron sheet 19 is hinged to the lower inner side of the connecting iron sheet 14, and the upper part of the connecting iron sheet 14 extends out of the seat frame 5 and is constructed with a clamping hole 23 connected to the backrest frame 6.

[0057] In the above technical solution, the motor is detachably designed between a pair of rear docking iron sheets and a pair of front docking iron sheets. When packaging, the seat frame can be hollowed out to maximize the space in the frame and improve the packaging utilization rate. When the motor is pushed forward, it can drive the front connecting iron pipe to move, thereby driving the first rotating iron sheet to rotate, and then pulling the transmission iron sheet to rotate the connecting iron sheet, and the backrest frame connected to the connecting iron sheet rotates and lies down. By controlling the motor, any stop point can be achieved, and the best comfort state can be found by each person according to their different weight.

[0058] like Figure 4 and Figure 8As shown, connectors 24 are fixedly provided on both sides of the lower part of the backrest frame 6, and the connectors 24 include a connecting shell 25 and a U-shaped connecting piece 26 arranged at the upper end of the connecting shell 25. An installation space is formed in the connecting shell 25, and a V-shaped spring-pressing piece 27 is formed at the lower end of the outer side of the U-shaped connecting piece 26. The upper part of the connecting iron sheet 14 extends into the installation space, and the inner end of the V-shaped spring-pressing piece 27 extends into the clamping hole 23 for clamping connection. In this technical solution, the backrest frame and the seat frame are detachably assembled through the clamping connection of the connector and the connecting iron sheet, which is very convenient for disassembly and assembly, can reduce the packaging volume, and is convenient for users to assemble.

[0059] A first plug-in piece 28 is fixedly provided on both sides of the upper part of the backrest frame 6. The first plug-in piece 28 is in a trapezoidal shape with a gradually decreasing diameter from top to bottom, and a first connecting groove with an open outer end is formed in the first plug-in piece 28; a second plug-in piece 29 is fixedly provided at the inner end of the back ear frame 8 to be plugged and matched with the first plug-in piece 28. The second plug-in piece 29 is in a trapezoidal shape adapted to the first connecting groove, and a second connecting groove with an open outer end is formed in the second plug-in piece 29. In this technical solution, the back ears and the backrest are plugged and assembled with two plug-ins, which is very convenient for assembly and disassembly, can reduce the packaging volume, and is convenient for users to assemble.

[0060] like Figure 4 As shown, the connecting iron sheet 14 includes an upper connecting sheet 30 and a lower connecting sheet 31, the lower connecting sheet 31 is located below the rear upper supporting iron tube 11, the upper connecting sheet 30 is located outside the rear upper supporting iron tube 11 and a notch 32 is formed between the upper connecting sheet 30 and the lower connecting sheet 31, which is against the rear upper supporting iron tube 11; the lower connecting sheet 31 is hinged with the transmission iron sheet 22 and the second fixed iron sheet 19 respectively. In this technical solution, the notch is against the rear upper supporting iron tube to achieve position limiting, so that when the motor is running, the upper connecting sheet rotates to the rear and outer sides to adjust the position of the backrest.

[0061] like Figure 1 and Figure 6 As shown, the turntable assembly includes a support frame 33 supported on the ground, a chassis 34 fixed on the support frame 33, a turntable 35 rotatably arranged on the chassis 34, and a connecting frame 36 fixed on the upper end of the turntable 35, and the connecting frame 36 is fixedly installed between the lower parts of the inner sides of the side iron frames 9 on both sides. In this technical solution, the support frame is placed on the ground in the accommodation space, and the chassis is fixed on the support frame. The turntable and the chassis are an integrated component, and the turntable can rotate relative to the chassis. The connecting frame is fixed on the upper end of the turntable, and the holes on both sides of the connecting frame are aligned with the holes of the side iron frames for fixed installation, so that the seat frame can be turned left and right 90 degrees respectively, which is more convenient for leisure.

[0062] like Figure 7As shown, a connecting rib 37 is fixedly provided below the upper tube of the side iron frame 9 along the length direction of the side iron frame 9, and the cushion fabric is installed on the connecting rib 37 through buckles. A convex ridge 38 is formed on the connecting rib 37 and is welded and fixed to the lower end of the upper tube of the side iron frame 9. In this technical solution, the cushion fabric is installed without nails. A connecting rib is provided on the side iron frame of the seat frame, and a number of buckles are installed on the cushion fabric. The several buckles are clamped on the connecting rib to fix the fabric, eliminating the traditional nail gun operation method, improving the operation time and efficiency, and making the product appearance neater and more beautiful. The convex ridge formed on the connecting rib is welded and fixed to the lower end of the upper tube of the side iron frame, which further fixes the connecting rib and prevents the connecting rib from being too long and bending.

[0063] In addition, the connecting piece assembly also includes a third rotating iron sheet 101 and a fourth rotating iron sheet 102, the two ends of the third rotating iron sheet are respectively hinged with the first fixed iron sheet and the fourth rotating iron sheet, the middle part of the third rotating iron sheet is fixedly connected with the second rotating iron sheet, and the other end of the fourth rotating iron sheet is hinged with the side iron frame. A reinforcing iron sheet is fixedly provided on the inner side of the front end of the side iron frame on both sides, one end of the fourth rotating iron sheet is hingedly provided between the reinforcing iron sheet and the side iron frame, and a foot plate 100 is fixedly provided on the outer end of the reinforcing iron sheet. In this technical solution, the third rotating iron sheet and the fourth rotating iron sheet can improve the rotational stability of the first rotating iron sheet and the second rotating iron sheet, improve the structural stability and strength of the connecting piece assembly as a whole, and extend the service life. The reinforcing iron sheet improves the connection strength of the fourth rotating iron sheet, thereby improving the connection strength of the connecting piece assembly as a whole with the outside. In addition, the reinforcing iron sheet is used to fix the foot plate, and the foot plate uses an iron pipe instead of a traditional layer board to reduce the phenomenon of mold and insect growth after the wood board is damp, and the iron pipe improves the firmness.

[0064] like Figures 16 to 20 As shown, a table top 41 can be hingedly provided on the armrest frame. A plurality of fixing holes 39 are correspondingly provided on the inner side of the armrest frame 7 and the outer side of the side iron frame 9, and at least two vertical beams 40 are fixedly provided on the outer side of the armrest frame 7, and these vertical beams 40 are hingedly connected to the table top 41 through hinges, so that the table top 41 can be flipped relative to the vertical beams 40 and maintained in a horizontal state under the action of external force, or flipped relative to the vertical beams 40 and restored to a vertical state.

[0065] Specifically, the hinge includes a short connecting section 108 and a long connecting section 109, and the short connecting section adapter frame is arranged on the outer side of the upper part of the long connecting section, and the two are relatively rotatably connected through a first connecting pin 110; Limiting holes 111 are longitudinally provided on both sides of the long connecting section, a second connecting pin 112 is passed through the lower part of the short connecting section, and a third connecting pin 113 is passed through the limiting holes on both sides, and both ends of the second connecting pin and the third connecting pin are respectively connected with limiting plates 114; when the short connecting section and the long connecting section rotate relative to each other, the limiting plates are driven to move, thereby pulling the third connecting pin to move longitudinally on the limiting hole; a locking member is provided in the connecting groove of the long connecting section, and the locking member is configured to lock the third connecting pin on the limiting hole when the short connecting section and the long connecting section are at a right angle. The locking member includes a U-shaped locking block 115, a fourth connecting pin 116 and a torsion spring. The fourth connecting pin is inserted through the long connecting section and the U-shaped locking block and is located outside the limiting hole. The torsion spring is sleeved on the fourth connecting pin. The U-shaped locking block is located outside the torsion spring. The torsion arms on both sides of the torsion spring abut against the upper and lower sides of the inner wall of the U-shaped locking block. When the third connecting pin moves upward, the upper part of the U-shaped locking block is squeezed and moved to the upper end of the limiting hole. Under the action of the torsion spring, the U-shaped locking block is reset to support the lower end of the third connecting pin, so that the third connecting pin can maintain the upper end of the limiting hole, thereby making the limiting plate and the second connecting pin in a locked state, and the table top is stable in a horizontal state. The multiple hinge designs can improve the load-bearing capacity of the table top. In this case, the two hinge designs make the table top load-bearing about 50KG, with high load-bearing capacity, which can meet daily use. When unlocking, just press the outer side of the U-shaped locking block, the inner end of the U-shaped locking block is raised, the third connecting pin falls, and the table top is reset. It should be noted that if the short connecting section is fixed on the vertical beam, the third connecting pin moves horizontally in the limiting hole. If the long connecting section is fixed on the vertical beam, the third connecting pin moves longitudinally in the limiting hole.

[0066] In this way, the table top can be maintained in a horizontal state after being opened, and can be used to place items or work. It can also replace the role of a side table and reduce the space occupied and configuration cost of the side table.

[0067] like Figures 9 to 15 A plurality of positioning holes 42 are correspondingly opened at the upper and lower ends of the two upper supporting iron pipes 11, and a hanging hook 43 is installed on the positioning hole 42. The hanging hook 43 includes a first annular buckle 44 and a second annular buckle 45 connected at one end, and a positioning nail 46 cooperating with the positioning hole 42 is provided on the inner wall of the first annular buckle 44 and the second annular buckle 45; a serpentine spring 47 is provided between the corresponding hanging hooks 43, and the two ends of the serpentine spring 47 pass through the elliptical clamping hole 48 to be connected with the hanging hook 43, and the two ends of the serpentine spring 47 form a bending section 49 for buckling the side end of the elliptical connecting block.

[0068] Multiple hooks are wrapped around the two upper supporting iron pipes, and the hooks are locked on the two upper supporting iron pipes through the positioning nails and positioning holes. The serpentine spring is connected between the corresponding hooks to play an elastic supporting role, so that the entire seat frame has good comfort and shock absorption effect. The friction between the hooks and the two upper supporting iron pipes is small, and the hooks are firmly fixed, which greatly reduces the occurrence of abnormal noise and improves comfort. The elliptical clamping hole has a good rebound effect, and the bending sections formed at both ends of the serpentine spring can effectively prevent the ends of the serpentine spring from detaching from the elliptical connecting block.

[0069] A fixed frame strip 105 and a fixed straight strip 103 are laid on the top of several serpentine springs, and the fixed frame strip and the fixed straight strip are tied and fixed to several serpentine springs by a fixing sleeve 104. The fixed frame strip and the fixed straight strip can reinforce multiple serpentine springs, and the existing frame strips use traditional paper-wrapped steel wire, which is easily affected by moisture, resulting in the product being not firmly fixed and falling off. The paper is bonded to the steel wire by glue, and the glue contains formaldehyde; the fixed frame strip and the fixed frame strip use PVC plastic-wrapped steel wire (PVC is wrapped with 3MM diameter steel bars), which is wrapped by melting plastic, without using glue, and will not be affected by moisture or fall off, thus extending the fixing time. In addition, the entire frame strip adopts a ring-shaped design to connect multiple serpentine springs together, and the reinforcement effect is more obvious during use, improving the performance of the serpentine spring and making the sitting feel more comfortable.

[0070] like Figure 1 As shown in 21-22, a plurality of rubber feet 50 are provided at the bottom of the side iron frame 9, and the rubber feet 50 include a main body 51 and a connecting rod 52 fixed to the upper end of the main body 51, and the connecting rod 52 is threadedly connected to the side iron frame 9. The main body 51 is truncated and the outer diameter gradually increases from top to bottom. The side wall of the main body 51 has a transitional curved surface, and the bottom surface of the main body 51 is formed with a deformable groove 53 on the inner side of the main body 51. In this technical solution, the rubber feet used in the seat are environmentally friendly and non-toxic. When the seat moves, the friction with the bottom plate can be reduced to avoid scratching the floor. The sound is small when moving, and it can automatically alleviate the shaking caused by slight uneven ground. The rubber material is heightened and the upper small and lower large structure can better play a buffering role and has a longer buffering distance, making the product using this foot more comfortable to sit on. The top connecting rod is threadedly connected to the seat, which is easy to install and not easy to fall off.
