Description

Technical Field

[0001] This utility model relates to the field of ergonomic support chair technology, specifically a self-locking gas spring ergonomic support chair with a portable exoskeleton. Background Technology

[0002] The inspiration came from a time when I was supervising a semiconductor FAB (Fabrication Equipment) factory. After standing and walking for a long time, I felt extremely fatigued. Since there were no chairs available and sitting on the ground was prohibited, I could only lean against a triangular cone for support and bend my knees to rest briefly. I thought about how, in a horse stance, the legs provide two supports. Adding another support would create a portable chair. After standing up, this chair could follow the worker like an exoskeleton, allowing them to sit or walk as needed. Combined with upper body and lumbar support, this could help maintain a neutral position, reduce fatigue and strain, improve work efficiency, and lower occupational injuries.

[0003] This product can be used for flat operations in factory workshops, laboratory work, office reception, warehouse material sorting, hospital care, and on-site supervision of engineering projects. However, the site conditions require a firm, flat surface without any vertical drop. Users need to have a certain level of balance control ability and can use it easily after training. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking gas spring ergonomic support chair for personal exoskeleton, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-locking gas spring ergonomic support chair for personal exoskeleton includes a support plate. Two connecting columns are fixedly installed on one side of the support plate. Each connecting column has a telescopic groove on one side, and a telescopic column is slidably installed inside the telescopic groove. Thigh fixing bolts are screwed to the bottom side of the connecting column to fix the telescopic column. One end of the telescopic column extends to the outside of the connecting column, and a hinge column is fixedly installed at one end of the telescopic column. A lower leg rod is hinged to the bottom of the hinge column. A second telescopic groove is opened on the bottom surface of the lower leg rod, and a lower leg telescopic rod is slidably installed inside the second telescopic groove. A lower leg fixing bolt is screwed to the bottom side of the lower leg rod to fix the lower leg fixing bolt. The bottom end of the lower leg telescopic rod extends to the outside of the lower leg rod and is fixedly installed with a support foot. A gas spring assembly is provided on the back of the hinge column and the lower leg rod to control the bending degree of the hinge column and the lower leg rod.

[0007] Preferably, a soft pad is fixedly installed on the upper surface of the support plate.

[0008] Preferably, a set of thigh straps is provided on both sides of the hinge column for binding and fixing the user's thighs, and a set of calf straps is provided on both sides of the calf bar for binding and fixing the user's calf.

[0012] Compared with the prior art, this utility model provides a self-locking gas spring ergonomic support chair for personal exoskeleton, which has the following beneficial effects:

[0013] 1. This portable exoskeleton-type self-locking gas spring ergonomic support chair, once worn, allows the user to bend their thighs backward and sit down on the cushion on the support plate when they want to rest. The hinge column drives the connecting rod and piston to slide inside the sleeve, compressing the inert gas inside the sleeve to achieve balance and facilitate support of the support plate. The user can sit on the seat to rest or work, reducing fatigue and strain, improving work efficiency, and reducing occupational injuries. By extending the cooperation between the support rod and the support leg, the friction between the support leg and the ground is increased, preventing slippage and thus increasing the stability of the support chair.

Detailed Implementation

[0020] Please see Figure 1-4 A self-locking gas spring ergonomic support chair for personal exoskeleton includes a support plate 1. Two connecting columns 3 are fixedly installed on one side of the support plate 1. Each connecting column 3 has a telescopic groove on one side. A telescopic column 4 is slidably installed inside the telescopic groove. A thigh fixing bolt 13 is screwed to the bottom side of the connecting column 3 to fix the telescopic column 4. One end of the telescopic column 4 extends to the outside of the connecting column 3. A hinge column 5 is fixedly installed at one end of the telescopic column 4. A lower leg rod 7 is hinged to the bottom of the hinge column 5. A second telescopic groove is opened on the bottom surface of the lower leg rod 7. A lower leg telescopic rod 9 is slidably installed inside the second telescopic groove. A lower leg fixing bolt 12 is screwed to the bottom side of the lower leg rod 7 to fix the lower leg fixing bolt 12. The bottom end of the lower leg telescopic rod 9 extends to the outside of the lower leg rod 7 and is fixedly installed with a support foot 10. A gas spring assembly is provided on the back of the hinge column 5 and the lower leg rod 7 to control the bending degree of the hinge column 5 and the lower leg rod 7.

[0021] Users can adjust the height of the support plate 1 by adjusting the position of the telescopic column 4 in the connecting column 3 according to their own height and comfort. After adjustment, the position of the telescopic column 4 is locked using the thigh fixing bolt 13. Similarly, users can adjust the position of the calf telescopic rod 9 in the calf rod 7. After adjustment, the position of the calf telescopic rod 9 is locked using the calf fixing bolt 12. This makes it easy to adjust the support leg of the device to a suitable length. After adjusting and wearing the device, when the user wants to rest, they can bend their thighs backward and sit down on the soft cushion 2 on the support plate 1. The hinge column 5 drives the gas spring assembly to retract to the balance point, which facilitates the support plate 1. Users can sit on the seat 5 to rest or work, reducing fatigue and strain, improving work efficiency, and reducing occupational injuries.

[0022] Furthermore, a soft pad 2 is fixedly installed on the upper surface of the support plate 1 to improve user comfort.

[0023] The hinge column 5 has a set of thigh straps 6 on both sides for binding and fixing the user's thighs, and the calf bar 7 has a set of calf straps 8 on both sides for binding and fixing the user's calf, making it convenient to wear the device on the user.

[0024] Furthermore, a connecting magnet 11 is fixedly installed at the front end of the support foot 10, and an iron block is fixedly installed at the user's heel. The front end of the support foot 10 is magnetically connected to the iron block at the user's heel through the connecting magnet 11 to ensure the stability of the support foot 10 and prevent slippage. An extension support rod is fixedly connected to the rear end of the support foot 10 to prevent the support foot 10 from slipping between itself and the ground.

[0025] Referring to the figure, the gas spring assembly includes a sleeve 14, the bottom end of which is hinged to the back of the lower leg rod 7. A piston 15 is slidably installed inside the sleeve 14. A connecting rod 16 is fixedly installed on the upper surface of the piston 15. The top end of the connecting rod 16 extends to the top of the sleeve 14 and is hinged to the back of the hinge post 5. An air inlet pipe 17 is fixedly installed on the lower side of the sleeve 14. The air inlet pipe 17 is connected to the inside of the sleeve 14 and a sealing valve 18 is provided on the air inlet pipe 17.

[0026] When the user needs to adjust the curvature of the hinge post 5 and the lower leg rod 7, by opening the sealing valve 18 to inflate or deflate the sleeve 14, the air pressure inside the sleeve 14 can be adjusted. This allows the piston 15 to slide at its lowest point inside the sleeve 14, thereby changing the relative position of the hinge post 5 and the lower leg rod 7 and achieving the adjustment of the curvature.

[0027] Furthermore, a pressure sensor 19 is fixedly installed on the bottom wall of the sleeve 14. The display end of the pressure sensor 19 is located outside the sleeve 14 to facilitate the display of the gas inside the sleeve 14. The user can easily adjust the internal pressure of the sleeve 14 according to the pressure sensor 19. An elastic sliding sleeve is provided on the inner wall of the top opening of the sleeve 14. The elastic sliding sleeve is fitted on the outer surface of the connecting rod 16 to prevent air leakage from the sleeve 14 from affecting the normal operation of the device.

[0028] Working principle: This portable exoskeleton self-locking gas spring ergonomic support chair allows users to adjust the height of the support plate 1 by adjusting the position of the telescopic column 4 in the connecting column 3 according to their own height and comfort. After adjustment, the position of the telescopic column 4 is locked using the thigh fixing bolt 13. Similarly, users can adjust the position of the calf telescopic rod 9 in the calf rod 7. After adjustment, the position of the calf telescopic rod 9 is locked using the calf fixing bolt 12, making it easy to adjust the support leg of the device to a suitable length.

[0029] The user places their thighs and buttocks on the support plate 1 and secures them with the thigh straps 6 to ensure stable support for the thighs. The user places their calves on the calf bar 7 and secures them with the calf straps 8 to ensure stable support for the calves. The front end of the support foot 10 is magnetically connected to the iron block at the user's heel via the connecting magnet 11 to ensure the stability of the support foot 10 and prevent slippage.

[0030] After the device is put on, when the user wants to rest, he bends his thighs backward and sits down on the cushion 2 on the support plate 1. The hinge column 5 drives the connecting rod 16 and the piston 15 to slide inside the sleeve 14, compressing the inert gas inside the sleeve 14 to achieve balance, which facilitates the support plate 1. The user can sit on the seat 5 to rest or work, reducing fatigue and strain, improving work efficiency, and reducing occupational injuries. By extending the cooperation between the support rod and the support foot 10, the friction between the support leg of the device and the ground is increased, preventing slippage and thus increasing the stability of the support chair.

[0031] When the user needs to adjust the curvature of the hinge post 5 and the lower leg rod 7, by opening the sealing valve 18 to inflate or deflate the sleeve 14, the air pressure inside the sleeve 14 can be adjusted. This allows the piston 15 to slide at its lowest point inside the sleeve 14, thereby changing the relative position of the hinge post 5 and the lower leg rod 7 and achieving the adjustment of the curvature.
