Description

Technical Field

[0001] This invention relates to the field of chair massage, specifically to a spinal calibration auxiliary massage device for occupational disease care. Background Technology

[0002] Office workers who sit for long periods and those who frequently use computers often experience spinal strain due to poor posture and prolonged work hours, leading to various cervical and lumbar spine problems. To alleviate spinal fatigue, people often use massage devices for auxiliary treatment, such as electric massage chairs. These chairs rely on massage components located on the backrest to relax muscles and massage acupoints, thereby relieving spinal fatigue.

[0003] Current office massage chairs, such as the ZG-AM21-B model, require users to lean back against the chair and maintain a fixed posture to fully utilize their massage function. Because the massage components on the backrest are fixed, if the user sits upright or in an improper posture while working, their body will move away from the backrest, significantly reducing the massage effect. Furthermore, due to prolonged sitting, and the lack of leg movement features in these chairs, blood circulation in the lower limbs slows down, consequently reducing overall blood circulation and the massage's effectiveness.

[0004] Therefore, a spinal alignment and massage device for occupational disease care is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a spinal alignment and massage device for occupational disease care, which, through an adaptive component, enables the chair back to provide a good massage effect even when the user is sitting upright, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A spinal alignment and massage aid for occupational disease care, comprising:

[0008] Chair back, seat cushion, armrests, gas spring, five-star base, casters, lumbar massage module, neck massage module, drive power source;

[0009] A gas spring is fixedly installed at the bottom of the seat cushion, a five-star base is fixedly installed at the bottom of the gas spring, and casters are fixedly installed at the bottom of the five-star base. A backrest is installed on the back of the seat cushion, a lumbar massage module is fixedly installed in the middle of the backrest, a neck massage module is fixedly installed on the upper part of the backrest, armrests are fixedly installed on both sides of the seat cushion, and a drive power source is fixedly installed at the bottom of the seat cushion.

[0010] Also includes:

[0011] An adaptation component is fixedly installed on the chair back, and the adaptation component is used to adjust the degree of fit between the human back and the chair back.

[0012] The lower limb movement device is fixedly installed at the bottom of the seat cushion. The lower limb movement device is used to assist lower limb movement and is beneficial to blood circulation.

[0013] Preferably, the adaptation component includes a support plate fixedly installed on the armrest, a rotating shaft rotatably installed on the support plate, a housing rotatably installed at both ends of the rotating shaft, a torsion spring fixedly installed inside the housing, the torsion spring being fixedly connected to the rotating shaft, the housing being fixedly connected to the support plate, and a limiting component fixedly installed on the rotating shaft near the backrest, the limiting component being used to fix the position of the backrest.

[0014] Furthermore, the limiting component includes a second outer shell fixedly mounted on a rotating shaft, a shaped ratchet fixedly mounted on the rotating shaft, the shaped ratchet located inside the second outer shell, the second outer shell being fixedly connected to the first outer shell, a support column fixedly mounted on the inner side wall of the second outer shell, a pawl rotatably mounted on the support column that cooperates with the shaped ratchet, a sliding groove being formed on the outer side wall of the second outer shell, a lever fixedly mounted on the pawl that cooperates with the sliding groove, a spring fixedly mounted inside the sliding groove, and the spring fixedly connected to the lever.

[0015] Furthermore, a damping shaft is provided at the connection between the first rotating shaft and the first support plate.

[0016] Furthermore, telescopic rods are fixedly installed at both ends of the rotating shaft, and springs are fixedly installed inside the telescopic rods. A rotating rod is fixedly installed at the moving end of the telescopic rod. A sliding groove is opened at the rear end of the upper surface of the cushion, and a slider is slidably installed in the sliding groove. The slider has a rotating groove that cooperates with the rotating rod. A moving groove is opened on the upper surface of the cushion and communicates with the sliding groove. A pad is slidably installed in the moving groove. Guide blocks are fixedly installed on both sides of the pad. Guide grooves that cooperate with the guide blocks are opened on both sides of the moving groove in the cushion. Springs are fixedly installed in the guide grooves and are fixedly connected to the guide blocks.

[0017] Furthermore, a top block is fixedly installed in the middle of the rotating shaft.

[0018] Unlike existing massage chairs that are integrated with the seat, the present invention features a separate design for the seat cushion and backrest. The seat cushion and backrest are hinged together and a torsion spring ensures that the user can still enjoy the massage service of the massage chair when sitting upright.

[0019] It is worth noting that when the user sits upright, the lower back is not perpendicular to the seat cushion, but tends to lean forward. However, this forward leaning angle is relatively small. If the user has a hunchback, the forward leaning tendency will be greater. Therefore, the initial angle between the backrest and the seat cushion is set to an acute angle, which is greater than the forward leaning angle of the user's lower back when working. Thus, when the user is working, it can be ensured that the backrest and the user's back have a certain degree of fit, thereby ensuring the massage efficiency of the massage chair.

[0020] Specifically, the angle between the backrest and seat cushion is typically an obtuse angle (approximately 110°–120°). The initial state of the torsion spring causes this angle to be approximately 70°–80°. When the user sits with their back against the backrest in a normal posture, the torsion spring's force causes the backrest angle to change. The extent of this change depends on the user's weight and the relaxation of their lower back. When the user is at rest, leaning their lower back against the backrest, the weight of their upper body acts on the torsion spring, causing the backrest angle to automatically adjust according to their upper body weight. When the user needs to work and straightens or bends over, the torsion spring returns to its initial state, causing the backrest to follow the user's back until it returns to its initial position.

[0021] The above describes the natural reclining posture during work breaks. When users are taking a lunch break or other rest periods and need to lie down, they can adjust their posture to apply all their upper body weight to the chair back, or push the armrests with both hands to provide more force to their back, causing a significant change in the chair back angle. This allows the user to achieve a near-flat reclining position. However, due to the relatively large reaction force of the torsion spring, maintaining a flat chair back requires continuous force from the user's back, causing discomfort. Therefore, utilizing the unidirectional rotation effect of a ratchet with a special gear, when the chair back rotates beyond a specified angle, the ratchet engages with the pawl, creating a self-locking mechanism. Thus, when the user is lying down, there is no need to additionally press down on the chair back with their body. Simultaneously, the friction between the lower limbs and the pad pushes the pad and guide block forward along the guide groove, allowing the user to lie down without excessive posture adjustment. Furthermore, at this time, the top block rotates out from the bottom of the pivot, gently supporting the user's lower back when the user lies down, relieving fatigue in the lumbar spine caused by prolonged bending. When the user wants to get up, they can push the lever to disengage the pawl from the ratchet, releasing the ratchet from its locked state, and using the rebound effect of the torsion spring to help the user sit up.

[0022] It should be noted that, in order to ensure that this massage chair has the same reclining function as a regular chair, even when the user leans against the backrest in a completely relaxed posture, the user's back weight is insufficient to make the backrest lie flat due to the resistance of the torsion spring. Only when the user leans back forcefully or relies on external force can the backrest lie flat.

[0023] When a user suddenly leans back, the chair back can rotate rapidly, startling the user. Similarly, if the user releases the ratchet lock while sitting upright, the rapid rebound of the chair back could cause injury. Furthermore, if the user stands up first and then releases the ratchet lock, the rebound of the chair back could also cause injury. Therefore, a damping pivot is installed at the junction of the pivot and the support plate to prevent sudden acceleration of the chair back.

[0024] Since the seat cushion is fixed, the second spring inside the telescopic rod is in a compressed state when the torsion spring is in its initial state. When the first pivot rotates clockwise in the initial state, it drives the telescopic rod to rotate clockwise, and the compressed second spring is released. At the same time, when the user leans back, the friction between the lower limbs and the seat cushion causes the second spring to compress, and the seat cushion slides outward along the slide groove to meet the user's comfort when leaning back. In addition, the top block fixed in the middle of the first pivot is rotated out, supporting the user's waist when the user leans back, increasing the user's comfort when leaning back.

[0025] The initial state of spring three within the slide is compressed, and the elastic force of spring three is greater than that of spring two. Therefore, even if the chair back is pushed when no one is sitting on the seat, the seat will not move. This prevents the seat from being pinched if the user pushes the chair back before sitting down.

[0026] Similarly, an adaptation component is provided at the upper part of the chair back. The difference is that the adaptation component is fixedly installed on the side of the chair back, and its effect is the same as that of the lower adaptation component, so I will not go into details here.

[0027] Preferably, the lower limb movement device includes a bracket fixedly installed at the bottom of the seat cushion, a second support plate fixedly installed on the bracket, a stabilizing plate fixedly and symmetrically installed on the side of the second support plate away from the bracket, a third support plate fixedly installed on the stabilizing plate, a second rotating shaft fixedly installed on the upper part of the third support plate, and a first pedal rotatably installed on the second rotating shaft.

[0028] Furthermore, the bracket includes two fixed posts, namely, a first fixed post and a second fixed post, which are respectively fixedly installed at the front and rear ends of the bottom of the seat cushion. An electric push rod is fixedly installed at the bottom of the first fixed post and the second fixed post.

[0029] Furthermore, one end of the second rotating shaft extends to the outside of the third support plate, and the end of the extended portion of the second rotating shaft is threaded. A second pedal is rotatably mounted on the outer wall of the extended portion of the second rotating shaft. A limiting cylinder that cooperates with the second rotating shaft is fixedly mounted on the side of the second pedal, and a friction plate that cooperates with the second rotating shaft is fixedly mounted inside the limiting cylinder.

[0030] Furthermore, the second surface of the rotating shaft is chrome plated.

[0031] The various lumbar spine problems caused by prolonged sitting for office workers also include lack of lumbar movement and poor blood circulation. By moving the user's feet on the pedal, the pedal undergoes a reciprocating rocking motion, increasing the user's exercise while providing a massage. Furthermore, the leg movements also stimulate the lumbar region, accelerating blood circulation and improving the efficiency of the massage.

[0032] The controller for the electric push rod can be located on the armrest. The position of the pedal is not fixed. When the massage chair is not in use, the electric push rod can be retracted to put the pedal back under the seat cushion, increasing the utilization of space.

[0033] The second pedal is fixedly connected to the limiting cylinder. Rotating the second pedal with the foot allows the limiting cylinder to engage with the second rotating shaft, moving the limiting cylinder closer to or away from the second rotating shaft. When the second pedal is rotated and the limiting cylinder is pressed tightly against the second rotating shaft, the second pedal is pressed against the third support plate, increasing the friction of the second rotating shaft and making it more difficult for the first pedal to swing, which is suitable for users with strong feet. When the user does not want the first pedal to swing, the limiting cylinder can be used to press the second rotating shaft, locking the second rotating shaft for easy foot placement.

[0034] Considering that if the user uses pedal one frequently, the pivot two will wear out due to prolonged friction with the support plate three. Furthermore, since the user's two feet exert different forces when using pedal one, the uneven force on both ends of pedal one can easily cause it to tilt. Therefore, a nickel plating layer is applied to pivot one to increase its service life.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. Equipped with an adaptation component, when the user is sitting upright, the initial angle between the backrest and the seat cushion is set to an acute angle, which is greater than the forward tilt angle of the user's waist when working. Therefore, when the user is working, the backrest can be guaranteed to fit the user's back to a certain degree, thereby ensuring the massage efficiency of the massage chair.

[0037] 2. It is equipped with a lower limb movement device. By using the user's feet on the pedal, the pedal will make a reciprocating swinging motion, which increases the user's exercise while massaging. In addition, the leg movement can also pull the waist movement, accelerate the body's blood circulation, and improve the efficiency of massage.

[0038] 3. Through the horizontal movement of the pad, as the user lies down, the friction between the lower limbs and the pad causes the pad and guide block to push forward along the guide groove, allowing the user to lie down without having to adjust their posture too much. At the same time, the top block rotates out from the bottom of the pivot, gently supporting the user's waist as they lie down, relieving fatigue in the lumbar spine caused by prolonged bending.

Detailed Implementation

[0050] Please see Figures 1 to 10 This invention provides a spinal alignment and massage device for occupational disease care, the technical solution of which is as follows:

[0051] A spinal alignment and massage aid for occupational disease care, comprising:

[0052] 1. Backrest, 4. Seat cushion, 2. Armrest, 7. Gas spring, 8. Five-star base, swivel casters, 101. Waist massage module, 102. Neck massage module, drive power source;

[0053] A gas spring 7 is fixedly installed at the bottom of the seat cushion 4. A five-star base 8 is fixedly installed at the lower part of the gas spring 7. A caster wheel is fixedly installed at the bottom of the five-star base 8. A backrest 1 is installed on the rear side of the seat cushion 4. A lumbar massage module 101 is fixedly installed in the middle of the backrest 1. A neck massage module 102 is fixedly installed on the upper part of the backrest 1. Armrests 2 are fixedly installed on both sides of the seat cushion 4. A drive power source is fixedly installed at the bottom of the seat cushion 4. The drive power source is used to drive the lumbar massage module 101 and the neck massage module 102.

[0054] Also includes:

[0055] An adaptation component is fixedly installed on the chair back 1. The adaptation component is used to adjust the degree of fit between the human back and the chair back 1.

[0056] The lower limb movement device is fixedly installed at the bottom of the seat cushion 4. The lower limb movement device is used to assist lower limb movement and is beneficial to blood circulation.

[0057] Example 1

[0058] When the user sits on the seat cushion 4, the electric push rod 502 is initially in the retracted state. The user places their foot on the pedal 6 and activates the controller of the electric push rod 502 located on the armrest 2. The electric push rod 502 extends the pedal 6 and the foot forward until the distance extended by the electric push rod 502 meets the user's requirements.

[0059] When the user is working, their back is lightly resting against the chair back 1. Under the action of the torsion spring 18, when the chair back 1 rotates to an angle of 80° to 90° with the horizontal, the reaction force of the torsion spring 18 is greater than the force exerted on the chair back 1 by the user's back when lightly resting. At this time, the user's neck is in a forward-leaning position. Under the action of the torsion spring 18, the pivot 14 at the top of the chair back 1 is initially at an obtuse angle with the horizontal, causing the upper part of the chair back 1 to contact the user's neck. The lumbar massage module 101 is located in the middle of the chair back 1, and the neck massage module 102 is located at the top of the chair back 1. Therefore, when the user is working normally, the waist can also get a good massage effect under the weight of the torsion spring 18 and the user's waist. However, most users tend to tilt their necks forward when working, so the massage effect will be reduced. The solution is to use the pad 22 to move the lower limbs forward by shifting it at the seat cushion 4, so that the waist can lean more against the backrest 1, increasing the force on the backrest 1. At this time, the angle of the line of sight can be changed slightly, so that the neck can get a better massage effect.

[0060] While receiving the massage, the user's feet can swing on the pedal 6 to activate the lower limbs, increase blood circulation, and thus enhance the massage effect.

[0061] The second pedal 609 is fixedly connected to the limiting cylinder 610. A friction plate 611 is fixedly installed inside the limiting cylinder 610. When the user places his foot on the second pedal 609 and swings it, the swinging difficulty of the first pedal 6 can be increased to meet the needs of users with strong foot strength. Conversely, it is beneficial to users with weak foot strength.

[0062] Example 2

[0063] When the user is at leisure, the force of the backrest 1 is greater. However, due to the action of the torsion spring 18, if the user wants to lie down, the backrest alone is not enough to compress the torsion spring 18 to meet the user's lying requirements. When the user needs to lie down, external force is required, such as pressing the foot pedal 6 to rotate the backrest 1 significantly backward. When the backrest 1 has rotated through the specified angle, the shaped ratchet 13 on the pivot 14 engages with the pawl 15, locking the shaped ratchet 13. Since the shaped ratchet 13 is fixedly connected to the pivot 14, the backrest 1 is thus fixed. As the user lies down, the friction between the lower limbs and the pad 22 pushes the pad 22 and the guide block 23 forward along the guide groove, allowing the user to lie down without having to adjust their posture too much. At this time, the top block 1902 rotates out from the bottom of the pivot, supporting the user's waist slightly when lying down, relieving fatigue of the lumbar spine caused by long-term bending.

[0064] When the user stands up, push the lever 11 to release the lock of the irregular ratchet 13. At this time, the force of the torsion spring 18 is greater than the weight of the user's back, and the user and the chair back 1 are slowly lifted up together.

[0065] If the user stands up first and then releases the locking mechanism of the ratchet 13, the rebound of the chair back 1 may cause injury. Therefore, a damping pivot is provided at the pivot 14 and the support plate 3 to prevent the chair back 1 from suddenly accelerating. Conversely, if the user suddenly pushes the chair back 1 forcefully, the damping pivot will reduce the rotation speed of the pivot 14 to avoid startling the user.
