Description

Technical Field

[0001] The present application relates to the technical field of chairs, and in particular to a spring chair. Background Art

[0002] Chairs, as a common piece of furniture, are widely used in various environments such as homes, offices, and public places. They are designed to provide a comfortable sitting or lying experience. Spring chairs are a type of chair that uses springs and other components to achieve a certain degree of cushioning and improve comfort.

[0003] Existing spring chairs, such as the one disclosed in publication number CN217852045U, have a seat plate that is elastic by providing a first spring and a second spring. When a user sits down, a difference in the sitting position is generated, and the user's buttocks feel a reciprocating elastic force, making it easier for the user to relax when sitting down to rest. This has achieved certain technical effects, but it still has limitations in terms of comfort. It can only provide short-term support at the moment of sitting down. After sitting down, it is not much different from a traditional chair, making it difficult to provide a continuous sense of comfort. Moreover, it cannot be folded, is inconvenient to carry, and has limited usage scenarios.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a spring chair to solve one of the above technical problems.

[0006] The technical solution adopted by this application to solve its technical problems is: a spring chair, comprising: a main support, including an armrest structure, a first support frame and a second support frame for providing support; a seat assembly, rotating on the main support, including a seat and a backrest, a sliding rod rotating at the connection between the seat and the seat surface, the sliding rod sliding in a sleeve, the lower end of the sleeve rotating on the first support frame, a spring arranged in the sleeve, the sliding rod contacting the top of the spring and not detaching from the sleeve.

[0007] In some embodiments, a connecting seat is fixed on the seat, the chair back rotates on the upper part of the connecting seat, and the sliding rod rotates on the lower part of the connecting seat.

[0008] In some embodiments, a rotating seat is provided on the first support frame, and the lower end of the sleeve rotates on the rotating seat.

[0009] In some embodiments, the sliding rod rotates while driving the sleeve to rotate slightly, and at the same time, the sliding rod slides in the sleeve.

[0010] In some embodiments, the sleeve, sliding rod and armrest structure are all arranged in pairs and symmetrically, and the two armrest structures are connected by a cross bar, which limits the maximum rotation amount of the seat assembly.

[0011] In some embodiments, a connecting member is also included, one end of which rotates on the second support frame, and an intermediate connecting rod rotates on the other end. The intermediate connecting rod is bent in an L shape, and its bending part rotates on the armrest structure. The cross bar is fixedly connected to the end of the intermediate connecting rod, and the first support frame rotates on the connecting member.

[0012] In some embodiments, rotating the second support frame toward the first support frame can fold the main frame, and rotating the chair back toward the seat can fold the seat assembly. At the same time, the connecting member and the intermediate connecting rod will also adaptively deflect and fold.

[0013] In some embodiments, the middle portion of the seat rotates on the second support frame and the connecting member, the top portion of the first support frame is fixed on the seat, and the top portion of the second support frame rotates on the seat.

[0014] In some embodiments, the first support frame includes telescopically extendable legs.

[0015] In some embodiments, the first support frame and the second support frame are non-foldable fixed structures.

[0016] The beneficial effects of the present application are that the seat assembly rotates on the second support frame and slides in the sleeve through the sliding rod thereon. The seat assembly compresses the spring when rotating, and the spring provides a restoring force, which can provide support when sitting down, allowing the user to feel relaxed. The spring chair can also serve as a rocking chair, providing a more comfortable use experience. In addition, the main frame and seat assembly of the spring chair are foldable, which reduces the space occupied when not in use, facilitates storage and transportation, and makes it have a wider range of usage scenarios.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0028] In the examples of this application, please refer to Figure 1-8 As shown, the spring chair mainly includes: a main bracket, including an armrest structure 1, a first support frame 2 and a second support frame 3, for providing support; a seat assembly 4, which rotates on the main bracket, including a seat 401 and a backrest 402, and a sliding rod 5 is rotated at the connection between the seat 401 and the chair surface, and the sliding rod 5 slides in a sleeve 6, and the lower end of the sleeve 6 rotates on the first support frame 2, and a spring 7 is arranged in the sleeve 6, and the sliding rod 5 contacts the top of the spring 7 and will not separate from the sleeve 6.

[0029] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0030] like Figure 1-3 As shown, a connecting seat 8 is fixed on the seat 401, the chair back 402 rotates on the upper part of the connecting seat 8, and the sliding rod 5 rotates on the lower part of the connecting seat 8, wherein the chair back 402 can only rotate within a limited range on the connecting seat 8, and when the seat assembly 4 rotates, the sliding rod 5 is driven to rotate synchronously.

[0031] Furthermore, a rotating seat 9 is provided on the first support frame 2 , and the lower end of the sleeve 6 rotates on the rotating seat 9 , wherein the sliding rod 5 rotates while driving the sleeve 6 to rotate slightly, and at the same time, the sliding rod 5 slides in the sleeve 6 .

[0032] Furthermore, the sleeve 6, the sliding rod 5 and the armrest structure 1 are all arranged in pairs and symmetrically. The two armrest structures 1 are connected by a cross bar 12. The cross bar 12 limits the maximum rotation of the seat assembly 4. When the seat assembly 4 rotates toward the cross bar 12, the sliding rod 5 slides into the sleeve 6 and compresses the spring 7. When the seat assembly 4 rotates away from the cross bar 12, the sliding rod 5 slides out of the sleeve 6 and the spring 7 stretches.

[0033] like Figure 5 As shown, it also includes a connecting member 10, one end of the connecting member 10 is rotated on the second support frame 3, and an intermediate connecting rod 11 is rotated on the other end. The intermediate connecting rod 11 is bent in an L shape, and its bending part is rotated on the handrail structure 1. The cross bar 12 is fixedly connected to the end of the intermediate connecting rod 11, and the first support frame 2 is rotated on the connecting member 10. In addition, the connection parts of the connecting member 10 and the first support frame 2 and the second support frame 3 are staggered up and down. Therefore, the connecting member 10 can be folded and stored synchronously when the first support frame 2 and the second support frame 3 are folded.

[0034] like Figure 7-8 As shown, rotating the second support frame 3 toward the first support frame 2 can fold the main frame, and rotating the chair back 402 toward the seat 401 can fold the seat assembly 4. At the same time, the connecting member 10 and the intermediate connecting rod 11 will also adaptively deflect and fold, and the armrest structure 1 can be rotated upward for storage.

[0035] Specifically, the middle part of the seat 401 rotates on the second support frame 3 and the connecting member 10, the top of the first support frame 2 is fixed on the seat 401, and the top of the second support frame 3 rotates on the seat 401. Therefore, when folding, the seat assembly 4 can be rotated and stored around the rotating axis between the seat 401 and the second support frame 3, while the second support frame 3 remains stationary, and folding and storage is achieved by rotating the first support frame 2 close to the second support frame 3.

[0036] Furthermore, the first support frame 2 includes a retractable extension leg 201, which can further reduce the space occupied when stored. In addition, when the spring chair is unfolded, it can be freely adjusted to a suitable position.

[0037] In one embodiment, the first support frame 2 and the second support frame 3 are non-foldable fixed structures.

[0038] The main body of this application is a main bracket and a seat assembly 4 that rotates thereon. The sliding rod 5 on the seat assembly 4 slides in the sleeve 6 of the built-in spring 7. When the seat assembly 4 rotates, the spring 7 can provide a restoring force, making the seat assembly 4 easier to rotate and more comfortable to use. In addition, the main bracket and the seat assembly 4 are foldable and can be easily carried and stored.

[0039] Thus far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
