Description

Technical Field

[0001] This application belongs to the field of exercise equipment, specifically relating to a foot and ankle joint exercise orthosis. Background Technology

[0002] Ankle orthotics are primarily used to treat and prevent ankle instability or injury caused by various factors. They help stabilize the ankle joint by providing external support, reducing the risk of sprains and promoting recovery after injury. These devices are particularly useful for people who frequently engage in high-intensity sports, as these activities increase the likelihood of ankle sprains. Furthermore, ankle orthotics are also suitable for older adults or individuals with conditions such as arthritis to increase stability in daily activities.

[0003] Using ankle orthotics can significantly improve ankle stability, reduce pain, and accelerate recovery. Especially after an acute sprain, proper use of an orthosis can help limit unnecessary movement and protect the injured area from further damage. Long-term use can also strengthen the muscles around the ankle, helping to prevent future injuries. Some more advanced ankle orthotics are also equipped with adjustable features, allowing for customized support levels and a more personalized treatment experience.

[0040] The corrective unit includes a housing 1, with a foot pedal 2 hinged to its top surface. A drive system is located inside the housing 1, controlling the foot pedal 2 to rotate around its pivot 201. The pivot 201 is located at one end of the foot pedal 2, and its end extends into the inner wall of the housing 1. The user places their foot against the foot pedal 2, stands upright, and adjusts the angle of the foot pedal 2 to change the angle between their foot and body, thereby achieving the purpose of exercising and correcting the ankle joint.

[0041] Two opposing upright plates 3 are provided on the top surface of the foot pedal 2 on one side of the pivot 201. Each upright plate 3 has a waist-shaped hole 301. The two upright plates 3 are connected by a support rod 4, which is fixed in position by a fastener 5 passing through the waist-shaped hole 301. The support rod 4 provides support for the user's heels. To improve comfort, the surface of the support rod 4 is covered with sponge.

[0042] The fastener 5 can be a fastening bolt. The fastening bolt passes through the slotted hole 301 and is threadedly connected to the threaded hole on the support rod 4. The fastening bolt is slidably connected to the slotted hole 301, so the position of the support rod 4 can be adjusted to suit different people.

[0043] The armrest includes a lower tube 13 and an upper tube 14 that are slidably connected. The lower tube 13 is detachably connected to the sleeve 12 on the housing 1 by plugging in. The lower tube 13 and the upper tube 14 are combined to form a telescopic rod, which can accommodate different heights. A handle 15 is fixed on the outer top of the upper tube 14 for easy gripping by the user. The handle 15 can be in various shapes, such as straight, U-shaped, or W-shaped.

[0044] The drive system includes a slide rail 7 arranged inside the housing 1, a slide rod 6 slidably mounted on the slide rail 7, and a support rod 8 between the slide rod 6 and the foot pedal 2. The two ends of the support rod 8 are hinged to the slide rod 6 and the foot pedal 2, respectively. To improve support force, a slide rail 7 is provided on each side of the slide rod 6, and at least two support rods 8 are hinged to the slide rod 6. The function of the drive system is to adjust the rotation angle of the foot pedal 2 and support the foot pedal 2 when rotated to a specified angle. Therefore, the drive system can be arranged in any of the following ways.

[0045] The first type: The slide rail 7 adopts an electric linear module, and the slide rod 6 is connected to the sliding part of the slide rail 7.

[0046] The second type: The slide rail 7 is a non-powered slide rail, and the slide rod 6 is connected to the sliding part of the slide rail 7. The driving system includes a driving unit, which controls the slide rod 6 to slide.

[0047] The drive unit is a telescopic device, and the end of the telescopic rod of the telescopic device is connected to the slide rod 6. The telescopic device can be an electric telescopic rod.

[0048] The third type: The slide rail 7 is a non-powered slide rail, and the slide rod 6 is connected to the sliding part of the slide rail 7. The driving system includes a driving unit, which controls the slide rod 6 to slide.

[0049] The drive unit includes a screw 9 and a drive assembly 10. The drive assembly 10 drives the screw 9 to rotate. The screw 9 is arranged perpendicularly to the slide bar 6 and is threadedly connected. The drive assembly 10 uses a servo motor.

[0050] Based on the above three drive system arrangements, a power module is provided inside the housing 1. The power module can include a battery or be powered externally. A control button is provided on the handle 15. The power module and the electronic control components of the drive system are electrically connected to the control button on the handle 15 through wires passing through the lower tube 13 and the upper tube 14. By touching or pressing the control button on the handle 15, the electronic control components of the drive system are operated to adjust the tilt angle of the foot pedal 2.

[0051] Since only wires need to pass through the inside of the handrail, the handrail can be made into a vertical bar or an arc bar.

[0052] The fourth arrangement of the drive system uses mechanical transmission, as detailed below:

[0053] The slide rail 7 is a non-powered slide rail, and the slide rod 6 is connected to the sliding part of the slide rail 7. The driving system includes a driving unit, which controls the slide rod 6 to slide.

[0054] The drive unit includes a screw 9 and a drive assembly 10. The drive assembly 10 drives the screw 9 to rotate. The screw 9 is arranged perpendicularly to the slide bar 6 and is threadedly connected.

[0055] The drive assembly 10 employs a bevel gearbox. One output shaft of the bevel gearbox is coaxially connected to the screw 9, and the other output shaft of the bevel gearbox is vertically upward and connected to a drive sleeve 11. The drive sleeve 11 is coaxially disposed inside the insert 12. The horizontal cross-sectional shape of the internal cavity of the drive sleeve 11 is non-circular, such as polygonal, star-shaped, or toothed.

[0056] The lower tube 13 includes a first outer tube 1301 and a rotating rod 1302 coaxially rotatably connected to the first outer tube 1301. The rotating rod 1302 is inserted into the drive sleeve 11, and the first outer tube 1301 is inserted into or threaded into the insert sleeve 12. The detachable connection between the armrest and the correction part is achieved through the insertion or threaded connection of the first outer tube 1301 and the insert sleeve 12. The threaded connection provides better tightness, while the insertion connection allows for the addition of rubber sleeves on the inner wall of the insert sleeve 12 and the bottom outer wall of the first outer tube 1301 to increase friction and thus enhance the stability of the connection.

[0057] The height of the insert 12 is lower than or equal to the height of the upright plate 3 when the foot pedal 2 is laid flat, which can further optimize the utilization of storage space.

[0058] To prevent the rotating rod 1302 from detaching from the first outer tube 1301, the lower part of the inner cavity of the first outer tube 1301 is provided with two spaced first retaining rings 13011, and the rotating rod 1302 is fitted with a coaxially arranged retaining post 13021, which is rotatably disposed inside the two first retaining rings 13011.

[0059] The upper tube 14 includes a second outer tube 1401 and a rotating tube 1402 coaxially rotatably connected inside the second outer tube 1401. To prevent the rotating tube 1402 from detaching from the second outer tube 1401, both the upper and lower ends of the rotating tube 1402 protrude to the outside of the second outer tube 1401. A second retaining ring 14021 is fitted on the rotating tube 1402 located outside the second outer tube 1401, and the outer diameter of the second retaining ring 14021 is larger than the outer diameter of the second outer tube 1401.

[0060] The outer diameter of the second outer tube 1401 is the same as the inner diameter of the first outer tube 1301, and the second outer tube 1401 is inserted inside the first outer tube 1301. The fixing method between the second outer tube 1401 and the first outer tube 1301 is existing technology. A threaded hole is provided at the upper end of the circumferential surface of the first outer tube 1301, and a fastening bolt is threaded into the threaded hole. The inner end of the fastening bolt abuts against the outer wall of the second outer tube 1401. The sliding and positioning of the second outer tube 1401 can be achieved by rotating the fastening bolt.

[0061] The inner diameter cross-sectional shape of the rotating tube 1402 and the cross-sectional shape of the rotating rod 1302 are both polygonal, and they have the same size. The rotating tube 1402 is sleeved on the outside of the rotating rod 1302.

[0062] The upper end of the second outer tube 1401 is fixed with a handle 15, and the upper end of the rotating tube 1402 is detachably connected with an adjusting handle 16. The adjusting handle 16 includes a handle 1601 and a plug rod 1602 that are coaxially fixedly connected. The cross-sectional shape and size of the plug rod 1602 are the same as those of the rotating rod 1302.

[0063] After the armrest is installed, the rod 1602 of the adjusting handle 16 is inserted into the rotating tube 1402 for adjustment; after the armrest is removed, the rod 1602 of the adjusting handle 16 is directly inserted into the drive sleeve 11 for adjustment.

[0064] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments.
