Description

Device for assisting foot stretching

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

The so-called drop foot is a clinical phenomenon of stroke. It is mainly due to factors such as damage to the central nervous system and abnormally high muscle tone of the posterior calf muscles. Action, and the phenomenon of foot drooping occurs. Foot drop phenomenon will cause patients to produce compensatory gait, such as raising the pelvis to avoid foot dragging, and using more hip and knee joints through a threshold gait to extend the time the foot is off the ground. The above-mentioned compensatory gait, on the one hand, will cause the patient to consume more muscle strength in walking, on the other hand, it will also easily cause the patient to fall and affect the safety of walking.

In response to the above problems, some companies have developed "a multi-purpose physiotherapy device for preventing foot sagging", such as the Chinese New Patent Announcement No. CN204636638U, which is mainly to wrap two cloth pads on the calf and forefoot, and put two cloth pads. It is connected by a spring, thereby using the elastic force of the spring to prevent the foot from sagging.

However, the above-mentioned previous proposal can only be used to partially improve the problem of foot drop, but not enough to improve the inversion of the foot. Secondly, the above-mentioned previous proposal does not have an adjustment function, and users cannot adjust appropriately according to their own needs.

In addition, the industry developed the "Foot Drop Orthotic Exerciser", such as the Chinese New Patent Announcement No. CN203059996U, which mainly includes a calf fixation device and a foot fixation device. The calf fixation device and the foot fixation 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, because the calf fixing device of the previous CN203059996U case is directly attached to the calf, when the user adjusts it in a sitting position, the calf needs to be raised in use, which is inconvenient to use.

For this, if you want to improve the phenomenon of foot drop caused by the excessive muscle tension of the posterior calf muscles, you can stretch the posterior calf muscles of the foot for a long time to reduce the abnormal muscle tension and improve the ankle joint Unlimited in the plantar flexion (plantar flexion) position, can make dorsiflexion movements. Accordingly, in order to better assist the foot stretching, the inventor proposes a device for assisting the foot stretching, which includes a wearing part and a stretching module. The wearing piece 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. There is a first connecting portion on one side, and an extension portion on the second side. The extension portion has a second connecting portion extending toward the front side relative to the heel support portion so that the second connecting portion deviates from the heel support portion . The stretching module is connected between the first connecting portion and the second connecting portion, the stretching module includes a stretching strap defining a forefoot support space, and the front The sole supporting space is adjacent to the heel supporting space.

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

Further, the adjustment mechanism may include a mounting seat and a rotating shaft, the mounting seat is fixedly mounted on the second connecting portion, the rotating shaft is pivoted to the mounting seat, and the rotating shaft is connected to the stretching belt , So as to tighten or loosen the stretch belt by rotating the shaft.

Further, there may be a ratchet gear on the rotating shaft; the adjusting mechanism may further include an engaging member that is movably connected to the mounting seat to be displaced to a latching position or an unlatching 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 to loosen the stretch belt.

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

Furthermore, the stretching module may further include a snap bead, and the elastic element provides an elastic force to the snap bead through the snap bead.

Further, the rotating shaft may include a winding part connected to the stretch belt; the mounting seat further includes a partition, the partition being located between the winding part and the ratchet gear between.

Further, the mounting seat may include a first shell seat and a second shell seat, and the partition board is sandwiched between the first shell seat and the second shell seat.

Further, there may be an opening between the first housing base and the partition; a toggle portion 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 stretch strap is connected to the second connecting part deviating from the heel support part, and can provide a stretching effect at an outwardly inclined angle, so in addition to stretching the forefoot to reduce the phenomenon of foot drop, it can also be used together Reduce the forefoot varus phenomenon to better stretch the foot.

2. The adjustment mechanism can have a height difference with the placement surface (for example, the ground), so that the user has space 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 tightness of the stretch belt to the required tightness, and enhance the safety and convenience of product use.

4. The clamping part of the adjustment mechanism can be used to operate the de-spinning gear, which is convenient and quick to loosen the stretch belt, which further improves the safety of product use.

Based on the above technical features, the main effects of the device for assisting foot stretching of the present invention will be clearly presented in the following embodiments.

The rotating shaft (24) can be pivoted to the mounting seat (23) through a pair of bearings (240), the pair of bearings (240) are respectively arranged on the first housing seat (231) and the second housing seat (232). The rotating shaft (24) may have a winding part (241) and a ratchet gear (242). The winding part (241) is used for connecting the stretching belt (21) to tighten or loosen the stretching belt (21) by rotating the rotating shaft (24). Please refer to the fourth and fifth figures again, the winding part (241) and the ratchet gear (242) are respectively located on both sides of the partition (233). One end of the rotating shaft (24) passing through the mounting seat (23) can be fixedly connected to a knob (243) by means of clamping, welding, locking, etc., for the user to operate and use. However, the rotating shaft (24) can also be connected to a motor to provide an electric adjustment mechanism.

Continuing to refer to the fourth figure and the sixth figure, the engaging member (25) is movably connected to the mounting base, for example, can be pivoted on a pivot of the first housing (231) of the mounting base (23) The shaft (235) can be displaced to a detent position or a detent position. The latching position is used to enable an engaging portion (251) of the engaging member (25) to engage the ratchet gear (242) to fix the rotating shaft (24). The elastic member (26) can provide an elastic force to the engaging member (25) through the locking bead (27), so that the engaging member (25) is located at the detent position. In this embodiment, the first housing (231) is provided with a containing groove (236) for containing the elastic member (26) and the retaining ball (27).

Please refer to the seventh figure in conjunction with the second figure. In addition, the engaging member (25) has a toggle portion (252) opposite to the engaging portion (251), and the toggle portion (252) extends The opening (234); when the user wants to release the stretch strap (21), the engaging member (25) can be displaced to the release position by operating the toggle portion (252) , The engaging member (25) is separated from the ratchet gear (242) to loosen the stretching belt (21).
