Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an elastic device. Background Technology

[0002] Sofas are an indispensable piece of furniture in modern homes, mainly used in living rooms, lounges and other places, to provide people with a comfortable sitting and lying experience.

[0003] Sofa designs and functions have evolved with the times to adapt to different lifestyles and personal preferences. For example, using a frame with flexible support ensures that the sofa is both comfortable and strong enough.

[0004] A typical sofa frame consists of a frame body and springs housed within the frame. These springs are usually serpentine springs, and there are several springs in total, with their ends connected to both sides of the frame body. These springs form an elastic cushioning section.

[0005] As can be seen, this structure results in a relatively long spring, which increases its cost. Furthermore, the large size of the spring makes assembly less convenient.

[0006] Chinese patent publication number CN 220109453U discloses a durable elastic seat frame and sofa. The elastic seat frame includes an elastic seat frame body and an elastic pad. The elastic seat frame body has a hollow area, and several serpentine springs are installed in the hollow area. The two ends of the serpentine springs are respectively fixed to the elastic seat frame body and are located on the same plane. The elastic pad is used to cover the hollow area, and the four sides of the elastic pad are connected to the elastic seat frame body. The serpentine springs are located below the elastic pad. This elastic seat frame and sofa effectively solves the problem of short sofa lifespan caused by friction of the elastic band and does not produce abnormal noise.

[0007] It can be seen that the aforementioned patents still suffer from the problem of relatively large size and large quantity of serpentine springs, which not only leads to high costs, but also results in high replacement costs when a single serpentine spring is damaged.

[0008] In addition, damage or deformation of a serpentine spring may affect adjacent serpentine springs, resulting in relatively poor stability. Utility Model Content

[0009] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an elastic device with high stability and a compact structure.

[0010] The objective of this utility model can be achieved through the following technical solutions:

[0011] An elastic device includes a frame in the shape of a square, characterized in that it further includes steel wires, springs, crossbars, hooks, and spacers. There are two crossbars, both horizontally located within the frame. There are several steel wires, evenly distributed along the length of the crossbars and connected between the two crossbars. The spring and hook are located at opposite ends of the frame. The spring connects one end of the frame to one of the crossbars, and the hook connects the other end of the frame to the other crossbar. The spacers are arranged parallel to the crossbars, and the steel wires are threaded through and connected to the spacers.

[0012] In the aforementioned elastic device, the number of spacers is at least three, and the three spacers are evenly distributed between the two crossbars.

[0013] In the aforementioned elastic device, the partition rod is a PE pipe, and steel wires are threaded through each partition rod.

[0014] In the above-mentioned elastic device, the end of the steel wire has a spiral cylindrical connecting part, and the number of turns of the connecting part is 1.5 to 3 turns.

[0015] In the above-mentioned elastic device, the spring includes a body in the shape of a helical cylinder and hooks located at both ends of the body. There is a straight connecting section between the body and the hooks. The connecting section is arranged in the radial direction of the body and the two ends of the connecting section are located on both sides of the body. One end of the connecting section is connected to the end of the body, and the other end of the connecting section is connected to the hook.

[0016] In the aforementioned elastic device, the hook, connecting section, and body are all integral structures.

[0017] In the above-mentioned elastic device, the inner side of the frame has a long, flat positioning piece. The positioning piece is located inside the frame and has a recessed connecting hole. The outer end of the hook is embedded in the connecting hole and connected to the positioning piece. The inner end of the hook is fastened to the crossbar.

[0018] In the aforementioned elastic device, the hook is U-shaped, with the outer end of the hook having a U-shaped bottom and a first fastening section that folds to the side, and the inner end of the hook having two U-shaped ends and a second fastening section that folds to the side. The first fastening section is connected to the connecting hole of the positioning piece, and the second fastening section is fastened to the crossbar.

[0019] In the aforementioned elastic device, the width of the hook matches the spacing between two adjacent steel wires, and the inner end of the hook is connected to the crossbar of the two adjacent steel wires.

[0020] In the above-mentioned elastic device, the crossbar and the connecting rod and steel wire form a support unit. The length of the support unit is A, the size of the spring is B, and the size of the hook is C, where A>B>C, and A is 10-20 times B.

[0021] Compared with existing technologies, this elastic device has hooks and springs at both ends of the support unit formed by the steel wire and crossbar. It can be seen that the support unit provides stable support. The hooks and springs not only stably connect the support unit to the frame, but the springs and steel wires also provide sufficient elasticity to ensure that the entire elastic device has sufficient comfort when used as a sofa seat frame.

[0022] Meanwhile, since the length of the spring is significantly smaller than the length of the support unit, the cost of the entire elastic device is relatively low. Furthermore, the two ends of the steel wire are stably connected to the corresponding crossbars, and the connecting section on the spring ensures sufficient connection strength between the spring and the crossbar, making it highly practical.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 As shown, this elastic device includes a square frame 1, and also includes steel wires 2, springs 3, crossbars 4, hooks 5, and spacers 6. There are two crossbars 4, both of which are horizontally located inside the frame 1. There are several steel wires 2, which are evenly distributed and connected between the two crossbars 4 along the length of the crossbars 4. The springs 3 and hooks 5 are located at both ends inside the frame 1. The springs 3 connect one end of the frame 1 to one of the crossbars 4, and the hooks 5 connect the other end of the frame 1 to the other crossbar 4. The spacers 6 are arranged parallel to the crossbars 4, and the steel wires 2 are threaded and connected to the spacers 6.

[0035] Both ends of the steel wire 2 are connected to the corresponding crossbars 4, and the steel wire 2 is also threaded through and connected to the partition rod 6. The steel wire 2, crossbars 4, and partition rod 6 form a support unit. The partition rod 6 in the support unit can prevent adjacent steel wires 2 from contacting each other, effectively ensuring the stability of the entire support unit.

[0036] One end of the support unit is connected to one side of the frame 1 via a spring 3, and the other end of the support unit is connected to the other side of the frame 1 via a hook 5.

[0037] During assembly, spring 3 first connects the support unit to frame 1. The corresponding assembly fixture then connects hook 5 between the support unit and the other side inside frame 1.

[0038] It can be seen that the support unit itself has a certain degree of elasticity. Combined with spring 3, this ensures that the entire elastic device has appropriate elasticity, providing sufficient elasticity and stability when used as a sofa seat frame.

[0039] The number of the partition rods 6 is at least three, and the three partition rods 6 are evenly distributed between the two crossbars 4.

[0040] Multiple spacers 6 can support and position the steel wire 2 at multiple locations along its length, effectively preventing adjacent steel wires 2 from contacting each other.

[0041] The partition rod 6 is a PE pipe, and the steel wire 2 is threaded through each partition rod 6.

[0042] The material of the spacer 6 allows the steel wire 2 to be smoothly and stably threaded and connected to it. Furthermore, the strength of the entire elastic device is improved, and its balance is better.

[0043] The end of the steel wire 2 has a spiral cylindrical connecting part 2a, which has 1.5 turns. Depending on the actual situation, it is also feasible to have 3 turns in the connecting part 2a.

[0044] This structure can improve the gripping force between the end of the steel wire 2 and the crossbar 4, preventing slippage.

[0045] The spring 3 includes a spiral cylindrical body 3a and hooks 3b located at both ends of the body 3a. There is a straight connecting section 3c between the body 3a and the hooks 3b. The connecting section 3c is arranged in the radial direction of the body 3a and the two ends of the connecting section 3c are located on both sides of the body 3a. One end of the connecting section 3c is connected to the end of the body 3a, and the other end of the connecting section 3c is connected to the hooks 3b.

[0046] As can be seen, compared with existing springs, the spring 3 in this patent application has an additional technical feature: a connecting segment 3c. This design optimizes the spring through the aforementioned structure, enabling the improved spring to withstand higher ultimate tensile strength. Furthermore, by reducing the size of the opening at the end of the spring 3, the spring 3 can be more stably and tightly connected to the crossbar 4, significantly reducing the risk of the spring 3 detaching.

[0047] The hook 3b, connecting section 3c, and body 3a are all integral structures.

[0048] This can appropriately improve the structural compactness of the entire spring 3.

[0049] The inner side of the frame 1 has a long, flat positioning piece 1a. The positioning piece 1a is located inside the frame 1 and has a recessed connecting hole 1a1. The outer end of the hook 5 is embedded in the connecting hole 1a1 and connected to the positioning piece 1a. The inner end of the hook 5 is fastened to the crossbar 4.

[0050] The protruding positioning piece 1a provides sufficient space for the connection hole 1a1 to be set. After the inner end of the hook 5 is engaged with the connection hole 1a1, the hook 5 can be conveniently and stably positioned and connected to the frame 1.

[0051] The hook 5 is U-shaped, with the outer end of the hook 5 having a U-shaped bottom and a fastening section 5a that folds to the side. The inner end of the hook 5 has two U-shaped ends and a fastening section 5b that folds to the side. The fastening section 5a is connected to the connecting hole 1a1 of the positioning piece 1a, and the fastening section 5b is fastened to the crossbar 4.

[0052] Both the first snap-fit ​​section 5a and the second snap-fit ​​section 5b are hook-shaped structures. Therefore, under the action of the first snap-fit ​​section 5a and the second snap-fit ​​section 5b, the entire hook 5 can be stably connected between the frame 1 and the crossbar 4.

[0053] The width of the hook 5 is matched with the spacing between two adjacent steel wires 2, and the inner end of the hook 5 is connected to the crossbar 4 of the two adjacent steel wires 2.

[0054] Because the hooks 5 and steel wires 2 are arranged adjacent to each other at intervals, and the U-shaped hooks 5 have sufficient width, the hooks 5 not only serve to stably connect the support unit to the frame 1, but also serve to separate the steel wires 2, ensuring that there is sufficient gap between adjacent steel wires 2.

[0055] The crossbar 4, the connecting rod 6, and the steel wire 2 form a support unit. The length of the support unit is A, the length of the spring 3 is B, and the length of the hook 5 is C, where A > B > C, and A is 10 times B. Depending on the actual situation, A being 20 times B is also feasible.

[0056] This structure allows for a relatively short length of spring 3. In other words, the support unit plays a major supporting role, and the elasticity of the entire elastic device is mainly provided by spring 3.

[0057] This elastic device features a support unit formed by steel wire and crossbar, with hooks and springs at both ends. As can be seen, the support unit provides stable support. The hooks and springs not only securely connect the support unit to the frame, but the springs, in conjunction with the steel wire, also provide sufficient elasticity, ensuring that the entire elastic device provides adequate comfort when used as a sofa seat frame.

[0058] Meanwhile, since the length of the spring is significantly smaller than the length of the support unit, the cost of the entire elastic device is relatively low. Furthermore, the two ends of the steel wire are stably connected to the corresponding crossbars, and the connecting section on the spring ensures sufficient connection strength between the spring and the crossbar, making it highly practical.

[0059] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
