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, the structure of the pressure arm assembly and load device in this design is relatively complex and 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 rear end of the pressure arm assembly is 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 is L-shaped overall, including a first pressure arm and a second pressure arm. The first pressure arm is a straight tube with one open end, and its rear end is fixedly connected to the pivot. The second pressure arm is L-shaped and consists of a vertical part and a horizontal part. The rear end of the vertical part is slidably disposed within the first pressure arm. The pressure arm assembly can be rotatably switched to the following two states:

[0007] Storage state: The first pressure arm is located on the side of the backrest, and the horizontal part of the second pressure arm is located above the top surface of the backrest;

[0008] Usage state: The second pressure arm rotates with the first pressure arm until its horizontal part is in front of the backrest.

[0009] Based on the above technical solutions, the pressure arm assembly in this application is L-shaped, including a first pressure arm and a second pressure arm. The vertical portion of the second pressure arm is slidably disposed within the first pressure arm. 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. In use, the second pressure arm can be flipped downwards 180 degrees and can extend and retract along the first pressure arm, getting closer to the human neck and improving comfort. This design also shortens the length of the first pressure arm, effectively saving storage space.

[0010] In the above technical solution, preferably, a shaft end limiting structure is provided between the vertical part of the second pressure arm and the first pressure arm to prevent the second pressure arm from coming out of the first pressure arm.

[0011] In the above technical solution, preferably, the shaft end limiting structure includes a limiting sleeve and a limiting plate. The limiting sleeve has a through hole that matches the vertical part. The limiting sleeve is fixed to the end of the first pressure arm. The limiting plate matches the inner cavity of the first pressure arm. The limiting plate is fixed to the end of the vertical part. When the limiting plate abuts against the inner end face of the limiting sleeve, it prevents the second pressure arm from being pulled out further.

[0012] In the above technical solution, preferably, the shaft end limiting structure includes a sliding groove and an adjusting knob that slides with the sliding groove. The sliding groove is disposed on the side wall of the first pressure arm and extends along the length direction. The adjusting knob passes through the sliding groove and is fixed to the vertical part of the second pressure arm.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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:

[0017] The pressure arm assembly can be rotated to switch between storage and use modes. This assembly consists of a first pressure arm and a second pressure arm, with the second pressure arm being L-shaped and including a vertical section and a horizontal section. The rear end of the vertical section slides inside the first pressure arm. In the non-use state, the pressure arm assembly can be flipped upwards above the backrest for compact storage, without affecting the seat's basic functions; the structure is simple and easy to operate. In the use state, the first pressure arm drives the second pressure arm to rotate to the front of the backrest, so that the horizontal section faces the user. Simultaneously, the second pressure arm can extend and retract along the first pressure arm to better fit the user's neck, improving comfort and individual adaptability. Furthermore, this design allows for a shorter overall length of the first pressure arm, further optimizing the utilization of storage space. Attached Figure Description

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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 L-shaped, and its rear end is 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 is rotated, and the load assembly 50 is stretched through the pivot 40, thereby providing load resistance for the rotation of the pressure arm assembly 30.

[0038] like Figure 3As shown, the pressure arm assembly 30 includes a first pressure arm 31 and a second pressure arm 32. The first pressure arm 31 is a straight tube open at one end, and its rear end is fixedly connected to the rotating shaft 40; the second pressure arm 32 is L-shaped and consists of a vertical part 321 and a horizontal part 322, with the rear end of the vertical part 321 slidably disposed within the first pressure arm 31. The pressure arm assembly 30 can be rotatably switched to the following two states:

[0039] Storage state: The first pressure arm 31 is located on the side of the backrest 20, and the horizontal part 322 of the second pressure arm 32 is located above the top surface of the backrest 20, as shown. Figure 7 As shown.

[0040] Usage state: The second pressure arm 32 rotates with the first pressure arm 31 until its horizontal portion 322 is located in front of the backrest 20. The user can use their chin to press against the horizontal portion 322 of the second pressure arm 32, causing the first pressure arm 31 to rotate downwards, such as... Figure 1 As shown.

[0041] like Figure 4 , Figure 5 As shown, the rear end of the vertical portion 321 of the second pressure arm 32 is slidably disposed within the first pressure arm 31, and a shaft end limiting structure is provided between the second pressure arm 32 and the first pressure arm 31 to prevent the second pressure arm 32 from coming out of the first pressure arm 31 when it is pulled out.

[0042] The shaft end limiting structure includes a limiting sleeve 33 and a limiting plate 34. The limiting sleeve 33 has a through hole 334 that matches the vertical part 321, and the limiting sleeve 33 is fixed to the end of the first pressure arm 31. The limiting plate 34 matches the inner cavity of the first pressure arm 31 and is fixed to the end of the vertical part 321. When the second pressure arm 32 is pulled outward, the limiting plate 34 abuts against the inner end face of the limiting sleeve 33, thus preventing the second pressure arm 32 from being pulled out further and preventing it from coming out of the first pressure arm 31, thereby achieving the limiting function.

[0043] The limiting sleeve 33 includes an insertion part 331 and a sleeve part 332. The shape of the insertion part 331 is adapted to the inner cavity of the first pressure arm 31, and a buckle 333 is provided on the outer wall. The shape of the sleeve part 332 is adapted to the first pressure arm 31. The insertion part 331 is inserted into the first pressure arm 31 and is fixed by the buckle 333. The sleeve part 332 of the limiting sleeve 33 abuts against the end of the first pressure arm 31.

[0044] The shaft end limiting structure can also adopt a limiting slide groove structure. Specifically, such as... Figure 6As shown, the shaft end limiting structure includes a slide groove 311 and an adjusting knob 35 that slides in conjunction with the slide groove 311. The slide groove 311 is located on the side wall of the first pressure arm 31 and extends along its length. The adjusting knob 35 passes through the slide groove 311 and is fixed to the vertical portion 321 of the second pressure arm 32. When the second pressure arm 32 is pulled out, the adjusting knob 35 abuts against the groove wall of the slide groove 311, thus limiting the further pulling out of the second pressure arm 32 and achieving the limiting function.

[0045] In this invention, the pressure arm assembly 30 has a simple structure and is easy to operate. The second pressure arm 32 and the first pressure arm 31 adopt a telescopic structure, which not only saves storage space, but also allows the distance to be adjusted according to the user's body size, thus improving user comfort.

[0046] 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.

[0047] The elastic element 52 can be made of elastic materials such as tension springs or elastic bands, and one or more can be configured according to actual needs. This application does not make specific limitations in this regard.

[0048] 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 cervical spine alignment.

[0049] Based on the above 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, it has the following significant advantages:

[0050] First, the pressure arm assembly consists of a first pressure arm and a retractable second pressure arm, with the first pressure arm rotatably mounted on the side of the backrest. When not in use, it can be flipped upwards and folded up above the backrest, without affecting the basic seating function of the chair. The structure is simple and the operation is convenient.

[0051] Secondly, during use, the distance between the horizontal part of the second pressure arm and the user can be adjusted by telescopic movement, making it fit the neck position better and improving comfort and adaptability. At the same time, this design shortens the overall length of the first pressure arm, effectively saving storage space.

[0052] 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 the user uses it, the head naturally rests in the groove, and the neck support applies forward support, creating a pushing and straightening effect on the cervical spine, which helps to relieve fatigue and promote the natural alignment of the cervical spine.

[0053] Fourth, this utility model uses common elastic elements such as tension springs and elastic bands as resistance devices, which are simple in structure, low in cost, and easy to produce and maintain.

[0054] 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.

[0055] 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.
