Description

Device for assisting foot stretching

The invention relates to a stretching device, especially a device for assisting stretching of the foot.

The so-called drop foot is a clinical phenomenon of stroke, mainly due to factors such as damage to the central nervous system and abnormally high muscle tone of the posterior calf muscles, which makes the ankle joint unable or difficult to dorsiflexion (Dorsiflexion). Movement, and the phenomenon of foot drop occurs. The foot drop phenomenon will lead to compensatory gait, such as raising the pelvis to avoid the foot from dragging the floor, and using more hips and knees through the cross-threshold gait to extend the time the foot leaves the ground. These compensatory gaits described above will cause patients to need to spend more muscle strength on walking. On the other hand, they will easily cause the patient to fall and affect the safety of walking.

In response to the above-mentioned problems, some developers have developed "a multi-purpose physiotherapy device for preventing foot drooping" such as Mainland China New Patent Announcement No. CN204636638U, which mainly wraps two cloth pads around the calf and the front of the foot, Connected with a spring, thereby using the elastic force of the spring to prevent the foot from sagging

However, the foregoing case can only be used to partially improve the problem of foot drop, but not enough to improve inversion of the foot. Secondly, the foregoing case does not have an adjustment function, and users cannot adjust it properly according to their own needs.

Another industry has developed "Foot Drop Orthopedic Exerciser" such as Mainland China New Patent Announcement No. CN203059996U, which mainly includes calf fixation devices and foot fixation devices, including calf fixation The device and the foot fixing device are connected by a connecting belt. The user can adjust the length of the connecting strap so that the calf fixing device can be adjusted to a comfortable position.

However, since the calf fixing device in the previous case of CN203059996U is directly sleeved on the calf, the user needs to raise the calf when using the sitting position for adjustment, which is inconvenient in use.

This is to improve the phenomenon of foot drop caused by excessive muscle tension of the posterior calf muscles. By stretching the posterior calf muscles of the feet for a long time, the abnormal muscle tension can be reduced and the foot and ankle joints can be reduced. Without being limited to the plantar flexion position, you can make dorsiflexion. Accordingly, in order to better assist the stretching of the foot, the inventor proposes a device for assisting the stretching of the foot, which includes a wearing part and a stretching module. The wearing part includes a first side, a second side, and a heel support portion, the heel support portion is located between the first side and the second side to define a heel support space, the first There is a first connecting portion on one side, and an extending portion on the second side, the extending portion extends to a front side relative to the heel support portion, so that the second connecting portion deviates from the heel support portion . The stretching module connects between the first connecting portion and the second connecting portion, the stretching module includes a stretching strap, the stretching strap defines a front foot support space, the front The sole support space is adjacent to the heel support space.

Further, the stretching module may further include an adjusting mechanism, and the stretching belt may be connected to the second connecting portion through the adjusting mechanism.

Further, the adjustment mechanism may include a mounting base and a rotating shaft, the mounting base is fixedly mounted on the second connection portion, the rotating shaft is pivotally mounted on the mounting base, and the rotating shaft is connected to the stretching belt , To tighten or loosen the stretching belt by turning the shaft.

Further, there may be a ratchet gear on the rotating shaft; the adjustment mechanism may further include an engaging member, the engaging member is movably connected to the mounting seat to be displaced to a detent position or a detent position, so The detent position is used to engage the ratchet gear to fix the rotating shaft, and the detent position is used to disengage the ratchet gear and loosen the tension band.

Further, the adjustment mechanism may further include an elastic member, the elastic member is connected to the engaging member, so that the engaging member is located to the latching position.

Further, the stretching module may further include a clamping bead, and the elastic member provides an elastic force to the clamping member through the clamping bead.

Further, the rotating shaft may include a winding portion, the winding portion is connected to the stretching belt; the mounting seat further includes a partition plate, the partition plate is located between the winding portion and the ratchet gear between.

Further, the mounting base may include a first shell base and a second shell base, and the partition plate is interposed between the first shell base and the second shell base.

Further, there may be an opening between the first shell seat and the partition; one of the toggle portions of the engaging member extends out of the opening.

Further, the second connecting portion may be located between a heel corresponding to a foot and a forefoot.

According to the above technical features, the following effects can be achieved:

1. The stretching band is connected to the second connecting part that deviates from the heel support part, and can provide the stretching effect of the outward inclination angle, so in addition to stretching the forefoot to reduce the phenomenon of hanging feet, it can also be The phenomenon of inversion of the forefoot is reduced to better stretch the foot.

2. The adjustment mechanism may have a height difference from the placement surface (for example, the ground), so that the user has room to operate the adjustment mechanism or the stretching belt, which improves the convenience of operation.

3. The use of the ratchet gear of the adjustment mechanism helps to gradually adjust the tension of the stretch belt to the required tightness and improve the safety and convenience of product use.

4. The engaging part of the adjustment mechanism can be used to operate the ratcheting gear, which facilitates the quick release of the stretching belt and further improves the safety of the product.
