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 for preventing lower limb venous thrombosis, promoting blood circulation, and maintaining or restoring ankle joint function. Flexion and extension exercises can effectively strengthen the muscles around the ankle. Patients lie supine or sit in bed, stretch and relax their lower limbs, then slowly raise and lower their toes, repeating this exercise. To enhance the effectiveness of these exercises, equipment may be used to apply resistance to the foot's movements.

[0003] For example, the Chinese patent 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 to actively exercise. It can also automatically perform functional exercises of the feet and ankles. It does not only rely on whether the patient can actively cooperate to prevent deep vein thrombosis in the lower limbs. It is easy to operate and can truly achieve regular functional exercises. It 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.

[0017] A receiving ring is provided at the end of the propulsion cylinder, and an abutment block is provided on the connecting cylinder, and the abutment block abuts against one group of the receiving rings; and

[0018] The overlapping ring is arranged on the receiving ring, and is slidably sleeved on an adjacent group of the mounting rods, and overlaps the receiving ring installed on the group of the mounting rods.

[0019] In a preferred embodiment, a buffer pad is provided at the end of the propulsion cylinder. The buffer pad is made of a flexible material and can abut against one group of the stop discs.

[0020] In a preferred embodiment, a knob is provided on the stop plate, the knob is rotatably provided on the mounting frame, an indicator needle is provided on the knob, and a gear line is circumferentially arranged on the mounting frame along the circumference of the knob.

[0021] In a preferred embodiment, the mounting frame is further provided with an indicating component for measuring the rotation angle of the pedal.

[0022] In a preferred embodiment, the indicator assembly includes:

[0023] A mounting shaft rotatably arranged on the mounting frame along its axis, and the pedal is fixedly arranged on the mounting shaft;

[0024] a scale needle, disposed at the end of the mounting shaft; and

[0025] Angle scale lines are arranged on the installation frame in a circumferential direction along the axis of the installation shaft.

[0026] In a preferred embodiment, the pedal is provided with multiple groups of rotatably mounted massage wheels, the massage wheels protrude from the surface of the pedal, and a guide frame is further provided at the bottom of the pedal, a drive plate is slidably provided in the guide frame, and multiple groups of grooves engaging with the massage wheels are provided on the drive plate, and a linkage assembly connected to the drive plate and the pedal is provided on the mounting frame, and the rotation of the pedal is converted into control of the reciprocating sliding of the drive plate through the linkage assembly.

The resistance generated by the exercise springs trains the patient's ankles. The number of exercise springs applying resistance can be quickly adjusted, allowing for quick and convenient adjustment of exercise intensity, making the device suitable for patients of varying ages and physical conditions.

[0034] 2. When the device is in use, the ankle is controlled to rotate to drive the pedal to rotate, and the pedal drives the driven gear to follow the movement. Since the driving gear is fixed by the teeth and cannot rotate, the driven gear rotates at the bottom of the pedal under the action of the meshing with the driving gear when following the movement of the pedal, thereby driving the drive plate to slide back and forth in the guide frame through the eccentrically hinged linkage rod. During the sliding process, the drive plate can drive the massage wheel to rotate through the cooperation of the multiple groups of grooves on the upper part of the drive plate and the massage wheel, so that the patient can massage the sole of the foot while exercising the ankle, thereby promoting blood circulation and improving the rehabilitation effect.

[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. Those skilled in the art 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, comprising a support frame 101, a mounting frame 104 disposed at one end of the support frame 101, a guide rod 106 fixedly disposed within the mounting frame 104, a connecting tube 402 slidably disposed on the guide rod 106 along its axis, a pedal 301 hingedly connected to the mounting frame 104, and straps disposed on both the support frame 101 and the pedal 301. The pedal 301 and the connecting tube 402 are connected via a drive assembly, which converts the movement of the pedal 301 into driving the connecting tube 402 to slide. The drive assembly comprises a connecting rod 401 and a return spring 404, one end of the connecting rod 401 being hingedly connected to the pedal 301 and the other end being hingedly connected to the connecting tube 402. The return spring 404 is sleeved on the guide rod 106, and its two ends respectively abut against the mounting frame 104 and the connecting tube 402.

[0053] When in use, the device can fix the support frame 101 on the calf through a strap, and fix the sole of the foot on the pedal 301. The pedal 301 is driven to rotate by hooking the toes backward or pressing the toes forward. During the rotation of the pedal 301, the connecting tube 402 is driven to slide along the guide rod 106 through the connecting rod 401. The connecting tube 402 can compress the return 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 return spring 404, thereby resetting the pedal 301.

[0054] like Figure 2 、 6As shown in Figures 7 and 8, in this embodiment, two sets of stop plates 503 are rotatably disposed within the mounting frame 104. Multiple sets of mounting rods 504 are circumferentially spaced apart between the two sets of stop plates 503. Exercise springs 509 are sleeved on the mounting rods 504. A connecting assembly is provided on the stop plates 503. When the stop plates 503 rotate to different angles, the connecting assembly causes the connecting cylinder 402 to compress different numbers of exercise springs 509 during its sliding process. The connecting assembly includes 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 exercise spring 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 overlapping ring 508 is provided on the receiving ring 507, and is slidably sleeved on an adjacent group of mounting rods 504, and overlaps 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 the first group of receiving rings 507, it can drive all the propulsion cylinders 505 to move to compress all the exercise springs 509. When the abutment block 403 overlaps with the last group of receiving rings 507, it can only drive the propulsion cylinders 505 on the group of receiving rings 507 to move, and then only control the compression of the corresponding exercise springs 509, so that the intensity of the exercise can be quickly adjusted.

[0056] like Figure 8 As shown, in this embodiment, a cushion 506 is provided at the end of the propulsion cylinder 505. The cushion 506 is made of a flexible material and can abut against one set of stop disks 503. The cushion 506 prevents the propulsion cylinder 505 from colliding with the stop disks 503 when resetting, thereby reducing noise during use of the device and providing a comfortable resting environment for the patient.

[0057] like Figure 1 、 7As shown, in this embodiment, a knob 501 is provided on a stopper plate 503, and the knob 501 is rotatably mounted on a mounting frame 104. An indicator needle 502 is provided on the knob 501, and a gear line 105 is arranged circumferentially along the circumference of the knob 501 on the mounting frame 104. The stopper plate 503 can be rotated by rotating the knob 501, and the rotation angle of the stopper plate 503 can be determined by observing the positions of the indicator needle 502 and the gear line 105, thereby making it easier to adjust the exercise angle.

[0058] like Figure 2 、 5 As shown, in this embodiment, the mounting frame 104 is further provided with an indicator assembly for measuring the rotation angle of the pedal 301. The indicator assembly includes a mounting shaft 201, a graduated needle 202, and angle scale lines 102. The mounting shaft 201 is rotatably mounted on the mounting frame 104 along its axis. The pedal 301 is fixedly mounted on the mounting shaft 201. The graduated needle 202 is disposed at the end of the mounting shaft 201. The angle scale lines 102 are circumferentially arranged on the mounting frame 104 along the axis of the mounting shaft 201.

[0059] As the ankle is controlled to rotate and the pedal 301 is driven to rotate, the pedal 301 drives the mounting shaft 201 to rotate, causing the graduated needle 202 to move along the angle scale line 102, thereby intuitively determining the angle of the patient's foot movement. Furthermore, in some embodiments, a counter connected to the mounting shaft 201 can be added to the mounting frame 104 to count the number of rotations of the mounting shaft 201. The installation of a counter is a common technique in the art and will not be further elaborated upon 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 further provided at the bottom of the pedal 301, and a drive plate 304 is slidably provided in the guide frame 303. The drive plate 304 is provided with a plurality of groups of grooves 305 that engage with the massage wheels 302. A linkage assembly connected to the drive plate 304 and the pedal 301 is provided on the mounting frame 104, and the rotation of the pedal 301 is converted into reciprocating sliding control of the drive 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 clamped on the driving gear 203. The driven gear 204 is rotatably provided along its axis at the bottom of the pedal 301 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 drive 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 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 provided on the upper side thereof and the massage wheel 302, so that the patient can massage the sole of the foot while exercising the ankle, thereby promoting blood circulation and improving the rehabilitation effect.

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

[0063] During use, the leg is secured to the support frame 101 and the foot is secured to the pedal 301. The pedal 301 can be rotated along its hinge point with the mounting frame 104 by moving the ankle. During rotation, the pedal 301 drives the connecting tube 402 via the driving assembly to slide along the axis of the guide rod 106. By rotating the stop plate 503 and, under the action of the connecting assembly, the stop plate 503 rotates to different angles, causing the connecting tube 402 to squeeze different numbers of exercise springs 509 as it slides. The resistance generated by the exercise springs 509 trains the patient's ankle. The number of exercise springs 509 applying resistance can be quickly adjusted, allowing for convenient and rapid adjustment of the exercise intensity, making the device suitable for patients of different ages and physical conditions.

[0064] The basic principles, main features, and advantages of the present invention are shown and described above. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications and improvements may be made based on the present invention, as will be apparent to those skilled in the art. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to fall within the scope of protection claimed in the present invention.
