Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis. Background Technology

[0002] Cervical spondylosis not only affects patients' physical health, but also has a significant negative impact on their quality of life and work ability.

[0003] To address this issue, Chinese utility model patent CN202314174U proposes a chair with functions for exercising facial and jaw muscles, neck muscles, and stretching the cervical spine. The chair features a rotatable shaft on the backrest, with a first arm and a second arm connected to its two ends. The ends of the arms are fixed by support arms, and a traction wire is fixed to the shaft, with the other end of the wire connected to a load device. Users can press down on the support arms with their chin, causing the arms and shaft to rotate, thereby driving the load device up and down. This exercises the facial, jaw, and neck muscles, stretches the cervical spine, and helps prevent cervical spondylosis or alleviate existing symptoms.

[0004] However, in this design, the structure of the pressure arm assembly and the load device is relatively complex, and during use, it is necessary to rotate the first and second arms on both sides separately before docking, which is not convenient to operate. Utility Model Content

[0005] To address the aforementioned shortcomings, the technical problem to be solved by this utility model is to provide a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis, thereby solving the problems of the existing technology having a relatively complex structure and being inconvenient to operate.

[0006] Therefore, this application provides a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis, including a seat and a backrest. The upper part of the backrest is provided with a pressure arm assembly. The pressure arm assembly is generally U-shaped, with its open end rotatably mounted on the side of the backrest via a pivot. A load-bearing component is disposed inside the backrest, and the pivot is coupled to the load-bearing component. The pressure arm assembly includes two first pressure arms and one second pressure arm. The first ends of the two first pressure arms are fixedly connected to the pivot, and the two ends of the second pressure arm are rotatably connected to the second ends of the two first pressure arms. The second pressure arm is arc-shaped, matching the shape of the top surface of the backrest. The pressure arm assembly can be switched to the following two states:

[0007] Storage state: The two first pressure arms are rotated to the side of the backrest, and the concave side of the second pressure arm faces the top surface of the backrest;

[0008] Usage state: The second pressure arm rotates with the first pressure arm to the front of the backrest, and its convex side faces the front of the backrest.

[0009] Based on the above technical solution, the pressure arm assembly in this application consists of two first pressure arms and one second pressure arm. The two ends of the second pressure arm are rotatably connected to the two first pressure arms, and the overall structure is arc-shaped, matching the top shape of the backrest. When the pressure arm assembly is not in use, it can be flipped upwards above the backrest without affecting the basic function of the seat; the structure is simple and easy to operate. When in use, the second pressure arm can be flipped downwards 180 degrees, so that its arc-shaped protrusion faces the user, getting closer to the neck and improving comfort. This design also shortens the length of the first pressure arms, effectively saving storage space.

[0010] In the above technical solution, preferably, the second end of the first pressure arm is provided with a stepped shaft hole, and two first stops are symmetrically arranged at the root of the stepped shaft hole. The end of the second pressure arm is provided with a connecting shaft, and two second stops are symmetrically arranged at the root of the connecting shaft. The connecting shaft is rotatably disposed within the stepped shaft hole, and the second stops cooperate with the first stops to achieve rotational limitation. This can prevent the second pressure arm from rotating during exercise, thus avoiding affecting the exercise effect.

[0011] In the above technical solution, preferably, the load assembly includes an upper pull arm, an elastic element, and a lower pull arm. The upper pull arm is fixed in the middle of the rotating shaft, the lower pull arm is fixed inside the backrest, and the upper and lower ends of the elastic element are respectively connected to the upper pull arm and the lower pull arm.

[0012] In the above technical solution, preferably, the elastic element is a tension spring or elastic band, which has a simple structure, low cost, does not require load adjustment, and is easy to use.

[0013] In the above technical solution, preferably, the upper end of the backrest is provided with a neck support, and the surface of the backrest above the neck support is provided with a groove to provide a cervical spine massage function.

[0014] As can be seen from the above technical solution, the health chair provided by this utility model for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis solves the problems of complex structure and inconvenient operation in existing technologies. Compared with the prior art, this utility model has the following beneficial effects:

[0015] The pressure arm assembly can be rotated to switch between storage and use modes. The assembly consists of two first pressure arms and a second pressure arm located between them, with both ends of the second pressure arm rotatably connected to the two first pressure arms. The second pressure arm is arc-shaped, conforming to the top contour of the backrest. When not in use, the entire pressure arm assembly can be rotated upwards to the upper part of the backrest for storage, without affecting the seat's basic functionality. In use, the second pressure arm can be rotated 180 degrees, so that the arc-shaped protrusion faces the user, thus providing a closer fit and shortening the effective length of the first pressure arms, further saving space. The overall structure is simple in design and easy to operate. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To provide a clearer explanation and description of the technical solution and implementation method of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0032] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0033] like Figure 1 , Figure 2 As shown, this utility model provides a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis. The health chair includes a seat 10 and a backrest 20, with a pressure arm assembly 30 located on the upper part of the backrest 20. The pressure arm assembly 30 is generally U-shaped, with its open end rotatably mounted on the side of the backrest 20 via a pivot 40. A load assembly 50 is located inside the backrest 20, and the pivot 40 is coupled to the load assembly 50. When the pressure arm assembly 30 is pressed down, the pivot 40 rotates, stretching the load assembly 50 and providing load resistance for the rotation of the pressure arm assembly 30.

[0034] like Figure 3 As shown, the pressure arm assembly 30 includes two first pressure arms 31 and one second pressure arm 32. The first ends of the two first pressure arms 31 are fixedly connected to the rotating shaft 40, and the two ends of the second pressure arm 32 are rotatably connected to the second ends of the two first pressure arms 31. The second pressure arm 32 is arc-shaped, matching the shape of the top surface of the backrest 20. The pressure arm assembly 30 can be switched to the following two states:

[0035] Storage state: The two first pressure arms 31 are located on the sides of the backrest 20, and the concave side of the second pressure arm 32 faces the top surface of the backrest 20, as shown. Figure 6 As shown.

[0036] Usage: The second pressure arm 32 rotates with the first pressure arm 31 to the front of the backrest 20, with its convex side facing the front of the backrest 20. The user can press the arc-shaped part of the second pressure arm 32 with their chin, causing both first pressure arms 31 to rotate downwards, as... Figure 1 As shown.

[0037] This application proposes an optimized design for the pressure arm assembly 30. The second pressure arm 32 is designed as an arc-shaped structure to match the top surface shape of the backrest 20. When the pressure arm assembly 30 is not in use, it can be rotated upwards above the backrest 20 without affecting the basic functions of the seat, such as... Figure 4 As shown.

[0038] Furthermore, the second pressure arm 32 can be rotated 180 degrees along the second end of the first pressure arm 31. In use, the user sits in the seat and rotates both first pressure arms 31 forward to a position approximately horizontal in front of the backrest 20, such as... Figure 5 As shown; then the second pressure arm 32 is rotated 180 degrees so that its convex side faces the user, as shown. Figure 1 As shown, the convex side of the second pressure arm 32 is closer to the user, making it easier to perform neck exercises.

[0039] The pressure arm assembly 30 of this invention has a simple structure and is easy to operate. Meanwhile, the optimized structure of the second pressure arm 32 shortens the length of the first pressure arm 31, effectively saving storage space.

[0040] like Figure 6 , Figure 7 As shown in the present application, the second pressure arm 32 is rotatably connected to the first pressure arm 31, and a flipping limiting structure is provided between them. Specifically, the second end of the first pressure arm 31 is provided with a stepped shaft hole 311, and two first stops 312 are symmetrically arranged on the stepped surface of the stepped shaft hole 311. The end of the second pressure arm 32 is provided with a connecting shaft 321, and two second stops 322 are symmetrically arranged at the root of the connecting shaft 321. The connecting shaft 321 is rotatably disposed in the stepped shaft hole 311. When the second pressure arm 32 rotates to 180 degrees, the second stops 322 abut against the first stops 312, realizing the rotation limiting function.

[0041] Please see again. Figure 3 The load assembly 50 includes an upper pull arm 51, an elastic element 52, and a lower pull arm 53. The upper pull arm 51 is fixed to the middle of the rotating shaft 40, which is rotatably mounted inside the backrest 20 via a fixed seat. The lower pull arm 53 is fixed in the internal structure of the backrest 20. The upper and lower ends of the elastic element 52 are connected to the upper pull arm 51 and the lower pull arm 53 respectively via connecting straps 54.

[0042] The elastic element 52 can be made of elastic materials such as tension springs or elastic bands, and one or more elements can be used depending on the actual needs of use. This application does not make any specific restrictions on this.

[0043] To improve user comfort, such as Figure 1 As shown, this application also provides a lumbar support 22 at the lower end and a neck support 23 at the upper end of the backrest 20, with both the lumbar support 22 and the neck support 23 protruding from the surface of the backrest 20. A groove 24 is provided on the surface of the backrest 20 above the neck support 23. During use, when the user leans back, their head naturally falls into the groove 24. At this time, the neck support 23 pushes forward on the cervical spine, helping to relieve cervical spine pressure and achieve proper cervical spine alignment.

[0044] Based on the above description of specific embodiments, this utility model provides a health chair for exercising neck muscles, stretching the cervical spine, and treating cervical spondylosis. Compared with the prior art, this health chair has the following significant advantages:

[0045] First, the pressure arm assembly consists of two first pressure arms and one second pressure arm, with both ends of the second pressure arm rotatably connected to the two first pressure arms. This second pressure arm is arc-shaped, matching the shape of the top of the backrest. The pressure arm assembly can be rotated to switch between a used state and a stored state. When not in use, it can be flipped upwards above the backrest without affecting the seat's basic functions. The overall structure is simple and easy to operate.

[0046] Secondly, during use, the second pressure arm can be rotated 180 degrees, so that the convex side faces the user and is closer to the neck, improving comfort. At the same time, this design also allows the length of the first pressure arm to be shortened, thus effectively saving storage space.

[0047] Third, a neck support is provided at the upper end of the backrest, and the backrest surface above the neck support has a groove that conforms to the contour of the head. When using the chair, the user's head can naturally rest in the groove, while the neck support applies forward pressure, providing support and compression for the cervical spine, which helps relieve cervical fatigue and promotes the natural alignment of the cervical spine.

[0048] Fourth, this utility model uses elastic elements such as tension springs and elastic bands as resistance devices, which has a simple structure and low manufacturing cost.

[0049] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0050] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
