Description

Technical Field

[0001] The present invention particularly relates to a foot exercise device. Background Art

[0002] Ankle exercises are very important for bedridden patients, especially to prevent lower extremity venous thrombosis, promote blood circulation, and maintain or restore ankle joint function. The muscles near the ankle can be effectively exercised by doing flexion and extension exercises. The patient lies on his back or sits on the bed, stretches and relaxes the lower limbs, then slowly lifts and presses the toes, and repeats the exercise. In order to improve the exercise effect, relevant equipment will be used to apply resistance to the movement of the foot.

[0003] For example, the Chinese patent with publication number CN209917151U provides an active foot exerciser for bedridden patients. The exerciser includes a fixed bracket, a spring, a display screen and a foot pedal. It can help patients to do active lower limb exercises and record the time, frequency and strength of the exercises, thereby promoting the confidence of patients in active exercises. It can also automatically perform functional exercises for the feet and ankles. It not only depends on whether the patient can actively cooperate, but also prevents deep vein thrombosis of the lower limbs. It is easy to operate, can truly achieve regular functional exercises, and is suitable for a wide range of people.

[0004] However, the existing foot exercise equipment has a relatively simple exercise effect, and the resistance it generates mostly remains constant, making it inconvenient to quickly adjust the exercise intensity level, thereby making it unsuitable for patients of different ages or physical conditions.

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0051] Example:

[0052] like Figure 1 , 2 As shown in Figures 6 and 7, the present invention provides a foot exercise device, including a support frame 101, a mounting frame 104 is provided at the end of the support frame 101, a guide rod 106 is fixedly provided in the mounting frame 104, a connecting tube 402 is slidably provided on the guide rod 106 along its axis, a pedal 301 is hinged on the mounting frame 104, and straps are provided on both the support frame 101 and the pedal 301. The pedal 301 is connected to the connecting tube 402 through a driving assembly, and the driving assembly converts the movement of the pedal 301 into driving the connecting tube 402 to slide. The driving assembly includes a connecting rod 401 and a return spring 404, one end of the connecting rod 401 is hinged to the pedal 301, and the other end is hinged to the connecting tube 402, and the return spring 404 is sleeved on the guide rod 106, and its two ends are respectively abutted against the mounting frame 104 and the connecting tube 402.

[0053] When the device is in use, the support frame 101 can be fixed to the calf through the straps, and the sole of the foot can be fixed to the pedal 301. The pedal 301 can be driven to rotate by hooking the toes backward or pressing the toes forward. During the rotation of the pedal 301, the connecting tube 402 can be driven to slide along the guide rod 106 through the connecting rod 401. The connecting tube 402 can compress the reset spring 404 during the sliding process. When the foot does not apply force, the connecting tube 402 is controlled to reset under the action of the reset spring 404, thereby resetting the pedal 301.

[0054] like Figure 2 , 6As shown in FIGS. 7 and 8, in this embodiment, two groups of stop disks 503 are rotatably arranged in the installation frame 104, and multiple groups of installation rods 504 are arranged circumferentially between the two groups of stop disks 503. The installation rods 504 are sleeved with exercise springs 509, and the stop disks 503 are provided with connecting components. When the stop disks 503 rotate at different angles, the connecting cylinder 402 can squeeze different numbers of exercise springs 509 during the sliding process through the connecting components. The connecting components include a propulsion cylinder 505, a receiving ring 507, and a lap ring 508. The propulsion cylinder 505 is provided with one group less than the number of mounting rods 504, and is slidably sleeved on the mounting rods 504 and abutted against the training springs 509. The receiving ring 507 is provided at the end of the propulsion cylinder 505. The connecting cylinder 402 is provided with an abutment block 403, and the abutment block 403 abuts against one group of receiving rings 507. The lap ring 508 is provided on the receiving ring 507, and is slidably sleeved on an adjacent group of mounting rods 504, and lapped on the receiving ring 507 installed on the group of mounting rods 504.

[0055] The stop plate 503 can be controlled to rotate to drive the abutment block 403 to abut against the receiving rings 507 at different positions. When exercising the ankle to drive the connecting tube 402 to slide, the abutment block 403 and the receiving ring 507 can be used to push one group of propulsion tubes 505 to slide on the mounting rod 504, thereby compressing the exercise spring 509. In addition, during the sliding process, the propulsion tubes 505 at different positions can drive different numbers of receiving rings 507 to move synchronously by abutting against the receiving rings 507 at corresponding positions, so as to compress different numbers of exercise springs 509. For example, when the abutment block 403 overlaps with a group of receiving rings 507 at the very beginning, it can drive all the propulsion cylinders 505 to move so as to compress all the exercise springs 509. When the abutment block 403 overlaps with a group of receiving rings 507 at the very end, it can only drive the propulsion cylinders 505 on this group of receiving rings 507 to move, and then only control the compression of the corresponding exercise springs 509, so that the intensity of exercise can be quickly adjusted.

[0056] like Figure 8 As shown, in this embodiment, a buffer pad 506 is provided at the end of the propulsion cylinder 505. The buffer pad 506 is made of a flexible material and can abut against one set of stop disks 503. The buffer pad 506 is provided to avoid collision between the propulsion cylinder 505 and the stop disk 503 when the propulsion cylinder 505 is reset, thereby reducing the noise of the device when in use and providing a comfortable resting environment for the patient.

[0057] like Figure 1 , 7As shown, in this embodiment, a knob 501 is provided on the stop plate 503, and the knob 501 is rotatably provided on the mounting frame 104. An indicator needle 502 is provided on the knob 501, and a gear line 105 is arranged in a circumferential direction along the circumference of the knob 501 on the mounting frame 104. The stop plate 503 can be driven to rotate by rotating the knob 501, and the rotation angle of the stop plate 503 can be known by observing the positions of the indicator needle 502 and the gear line 105, so that the adjustment of the exercise angle is more convenient.

[0058] like Figure 2 , 5 As shown, in this embodiment, the mounting frame 104 is also provided with an indication component for measuring the rotation angle of the pedal 301. The indication component includes a mounting shaft 201, a scale needle 202 and an angle scale line 102. The mounting shaft 201 is rotatably arranged on the mounting frame 104 along its axis, the pedal 301 is fixedly arranged on the mounting shaft 201, the scale needle 202 is arranged at the end of the mounting shaft 201, and the angle scale line 102 is circumferentially arranged on the mounting frame 104 along the axis of the mounting shaft 201.

[0059] In the process of controlling the ankle rotation and driving the pedal 301 to rotate, the pedal 301 drives the installation shaft 201 to rotate, so that the scale needle 202 moves on the angle scale line 102, and the angle of the patient's foot movement can be intuitively known. In addition, in some embodiments, a counter connected to the installation shaft 201 can be added to the installation frame 104, and the number of times the installation shaft 201 rotates can be counted by the counter. The installation of the counter is a common technical means in this field and will not be repeated here.

[0060] like Figures 2 to 5 As shown, in this embodiment, a plurality of groups of rotatably mounted massage wheels 302 are provided on the pedal 301, and the massage wheels 302 protrude from the surface of the pedal 301. A guide frame 303 is also provided at the bottom of the pedal 301, and a driving plate 304 is slidably provided in the guide frame 303. The driving plate 304 is provided with a plurality of groups of grooves 305 that mesh with the massage wheels 302. A linkage assembly connected to the driving plate 304 and the pedal 301 is provided on the mounting frame 104, and the rotation of the pedal 301 is converted into controlling the reciprocating sliding of the driving plate 304 through the linkage assembly. The linkage assembly includes a driving gear 203, a driven gear 204 and a linkage rod 205. The driving gear 203 is rotatably sleeved on the mounting shaft 201. The mounting frame 104 is provided with a latch 103, and the latch 103 is latched on the driving gear 203. The driven gear 204 is rotatably arranged at the bottom of the pedal 301 along its axis and meshes with the driving gear 203. The diameter of the driven gear 204 is smaller than that of the driving gear 203. One end of the linkage rod 205 is eccentrically hinged to the driven gear 204, and the other end is hinged to the driving plate 304.

[0061] When the ankle is controlled to rotate to drive the pedal 301 to rotate, the pedal 301 drives the driven gear 204 to follow the movement. Since the driving gear 203 is fixed by the latch tooth 103 and cannot rotate, the driven gear 204 rotates at the bottom of the pedal 301 under the meshing action with the driving gear 203 when following the movement of the pedal 301, thereby driving the driving plate 304 to slide back and forth in the guide frame 303 through the eccentrically hinged linkage rod 205. During the sliding process, the driving plate 304 can drive the massage wheel 302 to rotate through the cooperation of the multiple groups of grooves 305 opened on the upper side and the massage wheel 302, so that the patient can massage the sole of the foot while exercising the ankle, so as to promote blood circulation and improve the rehabilitation effect.

[0062] Specific usage and beneficial effects of the present invention:

[0063] When the device is used, the legs are fixed on the support frame 101, and the feet are fixed on the pedal 301. The pedal 301 can be driven to rotate along the hinge point between the pedal 301 and the mounting frame 104 by moving the ankle. During the rotation of the pedal 301, the connecting tube 402 is driven by the driving assembly to slide along the axis of the guide rod 106. By rotating the stop plate 503 and making the stop plate 503 rotate at different angles in the connecting assembly, the connecting tube 402 can squeeze different numbers of exercise springs 509 during the sliding process, and the patient's ankle can be trained through the resistance generated by the exercise springs 509. The number of exercise springs 509 that apply resistance can be quickly adjusted, so that the exercise intensity can be adjusted quickly and conveniently, so that the device is suitable for patients of different age groups or physical conditions.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
