Description

Technical Field

[0001] This utility model relates to the field of seat cushions, and in particular to a spring seat cushion. Background Technology

[0002] In today's society, many people need to sit for long periods of time, including but not limited to office clerks, factory control technicians, drivers, and people with leg disabilities. However, the cushions of existing chairs generally provide elasticity through foam, which easily collapses and breaks down after a period of use. To address this, some cushions on the market use springs to provide elasticity. However, in these cushions, the springs and the pad are fixedly connected, making spring installation cumbersome and disassembly and maintenance difficult if the pad or spring is damaged later. Separating the spring ends from the pad and placing them directly on the pad causes the spring ends to easily deviate during expansion and contraction, resulting in poor structural stability of the spring.

[0003] Therefore, existing spring seat cushions suffer from problems such as cumbersome replacement and maintenance operations and poor structural stability. Utility Model Content

[0004] The purpose of this invention is to provide a spring seat cushion. This invention not only allows for easy disassembly and maintenance, but also has the advantage of good structural stability.

[0005] The technical solution of this utility model is as follows: A spring seat cushion includes an outer cover with an opening and a zipper connected to the opening; an upper pad and a lower pad are arranged at intervals inside the outer cover, the upper and lower pads are the same size and are arranged opposite each other, and multiple springs are sandwiched between the upper and lower pads in an array; a protruding limiting ring is fixed on the bottom surface of the upper pad and the top surface of the lower pad at the position corresponding to the end of each spring, and the limiting ring is arranged to limit the spring ring end on the inner side, outer side or inner and outer sides; multiple flexible connecting strips connect the upper and lower pads.

[0006] In the aforementioned spring seat cushion, multiple connecting straps are connected between the edges and the center of the upper and lower pads.

[0007] In the aforementioned spring seat cushion, the connecting strap is detachably connected to the upper and lower pads.

[0008] In the aforementioned spring seat cushion, the connecting strap is a rope, and the two ends of the rope are respectively riveted and fixed with a male buckle and a female buckle; the upper and lower pads are provided with hanging holes for the rope to pass through at the position corresponding to each rope.

[0009] In the aforementioned spring seat cushion, both the upper and lower pads are provided with multiple ventilation holes.

[0010] In the aforementioned spring seat cushion, both the upper and lower pads are rectangular; the four corners of both the upper and lower pads are rounded.

[0011] In the aforementioned spring seat cushion, the top and sides of the outer cover are both perforated mesh.

[0012] In the aforementioned spring seat cushion, the height of the limiting ring is 3-15mm.

[0013] In the aforementioned spring seat cushion, the diameter of the spring is 20mm to 60mm; the wire diameter of the spring is 1mm to 2mm.

[0014] In the aforementioned spring cushion, the spring is a tower-shaped compression spring, a cylindrical compression spring, a Bonnell spring, or a drum-shaped spring.

[0015] Compared with existing technologies, this utility model features an opening with a zipper on the outer casing for easy access to the upper and lower pads. Multiple springs arranged in an array are sandwiched between the upper and lower pads, with protruding retaining rings fixed to the bottom and top surfaces of the upper and lower pads at the positions corresponding to each spring. These retaining rings are positioned on the inner, outer, or both sides of the spring's annular end, thus improving spring positioning and structural stability. Furthermore, the spring ends can be pulled away from the retaining rings, allowing for easy replacement and maintenance of the springs, upper and lower pads. Multiple flexible connecting straps connect the upper and lower pads, ensuring a closer fit between the springs and the pads, resulting in a more stable overall structure, less friction between components, and less noise, thus extending service life. Simultaneously, the connecting straps do not hinder the movement of the springs from the upper pad towards the lower pad and prevent excessive opening of the upper and lower pads, which could cause the spring ends to detach from the retaining rings, further improving structural stability.

[0016] In addition, the upper and lower pads of this invention are connected by multiple connecting strips at their edges and center, which makes the connection between the upper and lower pads more stable and can better ensure the stability of the spring between the upper and lower pads.

[0017] By making the connecting strap detachably connected between the upper and lower pads, the upper and lower pads can be separated and disassembled, making the replacement and maintenance of the upper and lower pads and springs more convenient.

[0018] The connecting strap is made easy to assemble and disassemble, and has high stability when connected by using a rope with male and female buckles riveted at both ends. The upper and lower pads are provided with hanging holes for the rope to pass through at the corresponding positions of each rope.

[0019] This spring seat cushion has been comprehensively optimized for breathability and comfort. Multiple ventilation holes are located on both the upper and lower panels, working in conjunction with the highly breathable compressible springs to create an efficient internal ventilation structure. Meanwhile, the top and sides of the outer cover feature a perforated mesh design to further enhance airflow. This double protection ensures excellent breathability throughout the cushion, effectively preventing stuffiness and dampness caused by prolonged sitting and helping to keep the contact surfaces dry. Furthermore, the four corners of both the upper and lower panels are rounded to prevent sharp edges from scratching the user. Combined with the springs' ability to conform to the body's curves and distribute pressure on the buttocks and lower back, this significantly improves comfort for those who sit for long periods.

[0020] Because of its simple shape, novel design, and easy assembly, this spring seat cushion meets the needs of different people and different scenarios, and can be industrialized.

[0021] By setting the height of the limiting ring to 3–15 mm, the end of the spring is less likely to detach from the limiting ring during use, thus ensuring the stability of the structure.

[0022] Therefore, this utility model not only facilitates disassembly and maintenance, but also has the advantages of good structural stability and good air permeability. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] Example. A spring seat cushion, configured as follows: Figures 1 to 5As shown, the device includes an outer cover 2 with an opening 1, and a zipper 3 connected to the opening 1. Inside the outer cover 2, there are upper pads 4 and lower pads 5 arranged at intervals. The upper pads 4 and lower pads 5 are the same size and are arranged opposite each other. Multiple springs 6 arranged in an array are sandwiched between the upper pads 4 and lower pads 5. On the bottom surface of the upper pads 4 and the top surface of the lower pads 5, at the position corresponding to the end of each spring 6, there are protruding limiting rings 7. The limiting rings 7 are arranged to limit the movement of the springs 6 on the inner, outer, or inner and outer sides of the annular ends. Multiple flexible connecting straps 8 connect the upper pads 4 and lower pads 5.

[0027] Multiple connecting straps 8 are connected between the edges and the center of the upper pad 4 and the lower pad 5; the connecting straps 8 are detachably connected to the upper pad 4 and the lower pad 5; the connecting straps 8 are ropes 9, and the two ends of the ropes 9 are respectively riveted and fixed with male buckles 10 and female buckles 11; the upper pad 4 and the lower pad 5 are provided with hanging holes 12 for the ropes 9 to pass through at the position corresponding to each rope 9.

[0028] Both the upper pad 4 and the lower pad 5 are provided with multiple ventilation holes 13.

[0029] Both the upper pad 4 and the lower pad 5 are rectangular; the four corners of both the upper pad 4 and the lower pad 5 are rounded.

[0030] The top and sides of the outer jacket 2 are both made of perforated mesh.

[0031] The height of the limiting ring 7 is 3-15mm.

[0032] The diameter of the spring 6 is 20mm to 60mm; the wire diameter of the spring 6 is 1mm to 2mm.

[0033] The spring 6 is a tower-shaped compression spring, a cylindrical compression spring, a Bonnell spring, or a drum-shaped spring.

[0034] Working principle: When the user sits on top of the cover 2, the upper pad 4 moves downwards towards the lower pad 5, compressing the multiple arrayed springs 6 between the upper pad 4 and the lower pad 5. After the user leaves the cover 2, the compressed springs 6 reset under their own elasticity, pushing the upper pad 4 back up. Because there are 3-15mm protruding limiting rings 7 fixed on the bottom surface of the upper pad 4 and the top surface of the lower pad 5 corresponding to the positions of the springs 6, and the limiting rings 7 are positioned on the inner, outer, or both sides of the annular end of the spring 6, the annular end of the spring 6 is less likely to shift during extension and retraction. Simultaneously, multiple flexible connecting straps 8 connect the edges and center of the upper pad 4 and the lower pad 5, resulting in high structural stability between the upper pad 4, the lower pad 5, and all the springs 6. Furthermore, during the extension and retraction of the springs 6, the upper pad 4 and the lower pad 5 will not open excessively, making it difficult for the annular end of the spring 6 to detach from the limiting rings 7. Because the upper pad 4 and the lower pad 5 are provided with multiple ventilation holes 13, the spring 6 itself is hollow, and the top and sides of the outer cover are hollow mesh, the overall breathability of the seat cushion is good; the four corners of the rectangular upper pad 4 and the lower pad 5 are rounded, so that the top corner of the seat cushion is not easy to scratch the user, thus improving the comfort during use.

[0035] When the seat cushion needs to be disassembled and maintained, simply unzip the zipper 3 at the opening 1 of the cover 2 to pull out the upper pad 4 and lower pad 5 from inside the cover 2; then, remove all the connecting straps 8 between the upper pad 4 and the lower pad 5 (separate the male buckle 10 and female buckle 11 at the end of the rope 9, and then pull the end of the rope 9 out of the hanging hole 12 of the upper pad 4); next, press down the lower pad 5 and pull it vertically upward to separate the upper pad 4 to replace the upper pad 4. Afterwards, you can also lift the spring 6 on the lower pad 5 upward to replace it; if you need to replace the lower pad 5, you can place the lower pad 5 facing upward, remove the connecting straps 8 on the lower pad 5, and then lift the lower pad 5 upward to replace it.
