Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to an arched elastic grid frame. Background Technology

[0002] The mesh frame in a spring cushion generally refers to the elastic fabric or mesh structure material used to connect and secure the springs, or to act as a support / cushioning layer, in seat cushions or seats equipped with a spring support system. It plays a crucial role in enhancing the comfort, breathability, durability, and structural stability of the cushion.

[0003] Current mesh frames typically present a grid-like structure, where several horizontal steel wires (wire 1) are interconnected with several vertical steel wires (wire 2). While this structure ensures the strength of the mesh frame, its elastic cushioning performance is poor. Furthermore, because the steel wires (wire 1 and wire 2) are in direct contact, friction between them during use generates noise, resulting in poor user comfort. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing an arched elastic grid frame with good buffering performance and high stability.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0006] An arched elastic grid frame includes two steel wires of metal material, one and two steel wires. There are two steel wires of the first type, which are arranged in parallel. The two ends of the steel wires of the second type are respectively connected to the corresponding steel wires of the first type. There are several steel wires of the second type, which are distributed along the length of the steel wires of the first type. The frame is characterized by further including a connecting pipe. The steel wires of the first type include straight rod segments one and two rod segments. The rod segments two are inclined to the rod segments one and the two rod segments two are symmetrically distributed at both ends of the rod segments one.

[0007] In the aforementioned arched elastic grid frame, the connecting pipe includes a straight pipe segment one and a pipe segment two. The pipe segment two is inclined to the pipe segment one and the two pipe segments two are symmetrically distributed at both ends of the pipe segment one.

[0008] In the aforementioned arched elastic grid frame, the second rod segment and the second pipe segment form an inclined connection area at the end of the entire grid frame, while the first rod segment and the first pipe segment form a flat load-bearing area in the middle of the entire grid frame.

[0009] In the aforementioned arched elastic grid frame, both the connecting area and the load-bearing area have several steel wires.

[0010] In the aforementioned arched elastic grid frame, the spacing between two adjacent steel wires in the connecting area is A, and the spacing between two adjacent steel wires in the bearing area is B, wherein B is greater than A.

[0011] In the aforementioned arched elastic grid frame, the connecting pipe is made of non-metallic material.

[0012] In the aforementioned arched elastic grid frame, the outer side of the steel wire has a covering layer that covers it, and the two ends of the steel wire have spirally wound connecting parts, which are sleeved on the covering layer and the two are tightly connected.

[0013] In the aforementioned arched elastic grid frame, one end of the steel wire has a hook with an opening facing downwards.

[0014] In the aforementioned arched elastic grid frame, the included angle between rod segment one and rod segment two is the same as the included angle between pipe segment one and pipe segment two, which is 140-170 degrees.

[0015] In the aforementioned arched elastic grid frame, the second steel wire has several convex and concave elastic segments along its length. The elastic segments on the second steel wire in the connecting area are on the same plane as the second rod segment and the second pipe segment. The elastic segments on the second steel wire in the bearing area are on the same plane as the first rod segment and the first pipe segment.

[0016] In the aforementioned arched elastic grid frame, the connecting pipe has several through-holes along its length, and the number of the through-holes is greater than the number of the steel wires.

[0017] In the aforementioned arched elastic grid frame, segment one and segment two are an integral structure.

[0018] In the aforementioned arched elastic grid frame, pipe segment one and pipe segment two are an integral structure.

[0019] Compared to existing technologies, this arched elastic grid frame has a larger number of steel wires in the connection areas, thus ensuring sufficient strength in these areas during use. Conversely, the relatively smaller number of steel wires in the support areas provides good elasticity without compromising cost. Therefore, the elastic pads using this grid frame offer excellent cushioning performance.

[0020] Meanwhile, steel wire one and steel wire two are not directly connected or in contact, so no excessive noise is generated during use, which effectively improves its stability and user comfort, and has high practical value. Attached Figure Description

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, this arched elastic grid frame includes steel wire 1 and steel wire 2 made of metal material. There are two steel wires 1, which are arranged in parallel. The two ends of the steel wires 2 are respectively connected to the corresponding steel wires 1. There are several steel wires 2, which are distributed along the length of the steel wires 1. It also includes a connecting pipe 4. The steel wire 1 includes a straight rod segment 11 and a rod segment 12. The rod segment 12 is inclined to the rod segment 11, and the two rod segments 12 are symmetrically distributed at both ends of the rod segment 11.

[0030] The connecting pipe 4 includes a straight section 42 and a second section 43. The second section 43 is inclined to the first section 42 and the two sections 43 are symmetrically distributed at both ends of the first section 42.

[0031] The aforementioned pole segment 12 and pipe segment 43 form an inclined connection area at the end of the entire grid frame, while the aforementioned pole segment 11 and pipe segment 42 form a flat load-bearing area in the middle of the entire grid frame.

[0032] Both the connecting area and the bearing area have several steel wires.

[0033] After steel wire 1 and steel wire 2 are connected, the connecting pipe 4 ensures that an appropriate distance is maintained between adjacent steel wires 2. Therefore, the entire arched elastic grid frame has both sufficient strength and good overall elasticity.

[0034] The connecting area and the load-bearing area are not on the same plane. Under the action of the connecting area, the entire grid frame forms an arched structure, which further improves its elasticity.

[0035] The spacing between two adjacent steel wires 2 in the connection area is A, and the spacing between two adjacent steel wires 2 in the bearing area is B, where B is greater than A.

[0036] In other words, the steel wires 2 are denser in the connection area. Since the connection area is connected to the corresponding seat frame, the connection area bears a relatively large force during use. The denser steel wires 2 can effectively improve the strength of the connection area.

[0037] The connecting pipe 4 is made of non-metallic material.

[0038] In this embodiment, the connecting pipe 4 is made of polyethylene. However, depending on the actual situation, it is also feasible to use polypropylene for the connecting pipe 4.

[0039] The outer side of the steel wire 1 has a covering layer 3 that covers it, and the end of the steel wire 2 has a spirally wound connecting part 21. The connecting part 21 is sleeved on the covering layer 3 and the two are tightly connected.

[0040] In this embodiment, the coating layer 3 is made of polypropylene. However, depending on the actual situation, it is also feasible to use polyethylene as the coating layer 3.

[0041] The covering layer 3 can prevent the steel wire 1 and the steel wire 2 from directly contacting each other, thus effectively reducing the noise generated during use.

[0042] The end of the steel wire 1 has a hook 13 with the opening facing downwards.

[0043] The hook 13 can effectively connect the entire grid frame to the corresponding seat frame.

[0044] The included angle between rod segment 11 and rod segment 12 is the same as the included angle between pipe segment 42 and pipe segment 43, which is 140 degrees. Depending on the actual situation, an included angle of 160 or 170 degrees is also feasible.

[0045] Within this angle range, the overall height of the grid frame will not be significantly increased, while also giving it good flexibility.

[0046] The second steel wire 2 has several elastic segments 22 with concave and convex shapes along its length. The elastic segments 22 on the second steel wire 2 in the connecting area are on the same plane as the second rod segment 12 and the second pipe segment 43. The elastic segments 22 on the second steel wire 2 in the bearing area are on the same plane as the first rod segment 11 and the first pipe segment 42.

[0047] The addition of elastic segment 22 further enhances the elastic performance of the entire elastic grid frame, enabling it to form a better buffer when subjected to force.

[0048] The connecting pipe 4 has several through connecting holes 41 along its length, and the number of connecting holes 41 is greater than the number of steel wires 2.

[0049] The number of steel wires 2 can be adjusted according to the actual situation. Therefore, after reserving more connecting holes 41 on the connecting pipe 4, it can accommodate the change in the number of steel wires 2.

[0050] The first pole segment 11 and the second pole segment 12 are an integral structure.

[0051] Pipe section 1 (42) and pipe section 2 (43) are an integral structure.

[0052] Because this arched elastic mesh frame has a relatively large number of steel wires in the connecting areas, it ensures sufficient strength in these areas during use. Conversely, the relatively smaller number of steel wires in the supporting areas provides good elasticity without compromising cost. Therefore, the elastic pads using this mesh frame offer excellent cushioning performance.

[0053] Meanwhile, steel wire one and steel wire two are not directly connected or in contact, so no excessive noise is generated during use, which effectively improves its stability and user comfort, and has high practical value.

[0054] This arched flexible mesh frame is compatible with various seating options, such as sofas, chairs, and swivel chairs. It can also be used on mattresses.

[0055] In addition, to ensure a more stable connection between the arched flexible mesh frame and the corresponding frame, some of the wires have hooks on their outer ends. These hooks, when engaged with the frame, further enhance the connection stability.

[0056] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0057] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
