Description

Stretching aid

This creation is about a kind of orthodontic equipment, especially a kind of bracing aid that can be operated by the user and is safe.

Maintaining the same posture for a long time tends to make the muscles tight. At this time, only moderate stretching can relieve the tight muscles. Therefore, for busy modern people, stretching is the simplest and cheapest exercise.

The human system is made up of bones and muscles that are connected in a crisscross pattern, and the human body often causes muscle strain during exercise. For example, running can cause discomfort such as soreness in the leg muscles due to the accumulation of lactic acid; especially for women, long Standing for time, or working in high heels for a day, the legs will swell and numb due to poor blood circulation, and even have varicose veins. At this time, some stretching or stretching exercises can be used to relieve muscle discomfort.

In recent years, as modern people pay more and more attention to health maintenance, fitness equipment that can relieve spinal nerves and improve back pain is becoming more and more common. The traditional lacing board in the market mainly uses the inclined board for the foot to stand, and the angle between the foot and the calf when standing is used to stretch the muscles of the lower limbs, and then stretch the muscles of the back of the thighs and the back at the same time. However, when the muscles are tight, the inclined board is actually not conducive to standing. The user must support other objects with both hands to slowly adjust the posture or center of gravity, and even rely on the hands to assist support during standing. For this reason, it is necessary to move the brace board to the vicinity of an object that can be supported by hands, which is very inconvenient. The above-mentioned conventional bracing board or other bracing equipment may easily cause the novice user to cause additional secondary sports injuries due to poor posture.

The purpose of this creation is to provide a stretching aid, which can be operated and set by the user according to the range of the soreness that can withstand the pain, so as to facilitate the effect of self-appropriate stretching for health care and correction.

The second purpose of this creation is to provide a stretching aid, which adopts the lying-down stretching action, which is safer than the conventional lower waist stretching action.

Another purpose of this creation is to provide a stretching aid, which is a stepless adjustment method for the user to operate and pre-set the height and angle of the leg lift.

Another purpose of this creation is to provide a lacing aid with a safety switch. When the user encounters any abnormal situation, the safety switch can be used to immediately turn off the power source to protect the user and ensure the safety of the entire use.

The stretching aid that can achieve the above-mentioned new purpose includes: a bed table for a user to lie on his back; a foot stretching board, the foot stretching board is pivotally connected to the end of the bed table, And can make a pendulum movement within a predetermined angle range relative to the bed; a restraint belt is fixedly arranged on the foot stretching board to bind a foot of the user to the foot stretching board On; a power source is fixedly arranged on the bottom surface of the bed, the power source drives the foot stretch plate to make a pendulum movement relative to the bed through a transmission device; and a control device for the user to operate The power source moves.

The stretching aid as described above, wherein the predetermined angle range is between 0 degrees and 90 degrees.

The stretching aid as described above, wherein the transmission device includes a connecting rod, one end of the connecting rod is pivotally connected to the back of the foot stretching plate, and the other end is connected to a transmission shaft of the power source; when the transmission When moving axially outward, the connecting rod drives the foot stretching plate to swing upward from the horizontal position to an operating angle set by the control device, and the maximum is not more than 90 degrees; when the transmission shaft moves back to the inside At this time, through the transmission of the connecting rod, the foot stretching board is swung downward from the operating angle to move back to the horizontal position.

The stretching aid as described above, wherein the control device is a wireless remote controller.

In the above-mentioned stretching aid, the power source is a stepping motor, and a gear transmission assembly is arranged between the connecting rod and the transmission shaft, so as to convert the rotary motion of the transmission shaft into the linear motion of the connecting rod.

In the above-mentioned stretching aid, the power source is a hydraulic cylinder, and the transmission shaft is the plunger rod of the hydraulic cylinder.

The stretching aid as described above further includes a safety switch, which can immediately shut off the power source when the safety switch is operated, and immediately stop the action of the foot stretching board.

The stretching aid as described above, wherein the strap is one of a hook and loop strap, a perforated belt, and a strap that can tighten the user's foot.
