A covering band is provided on the surface of the supporter body so as to overlap with a pair of tongue pieces at both ends, and is mounted with a surface fastener (for example, utility model registration 3010008).
[0003]
[Problems to be solved by the invention]
Conventional knee bands are equipped with leaf springs on both sides of the knee of the stretchable covering band, so soft tissue or joint (bone shape) changes in the knee joint during walking, so the knee joint The joint axis and the mechanical axis of the knee band did not match, causing the knee band to slide down or rotate. In addition, the pad of the patella is not provided with a pad with good adaptability to prevent slippage, and the followability of movement is poor, and because the material is made of elastic natural rubber and polyester, it is a material for bending and stretching exercises during walking The patella, femoral-tibial joint and ligament are weakly supported due to excessive stretching, and the conventional band is passive, and has an active function to support walking and promote walking without kicking the front of the lower leg during walking There was a problem that there was no concept of a knee band.
[0004]
In the present invention, the knee band is divided into a fixed portion and a stretchable portion, and the patella portion of the fixed portion is covered with a non-stretchable cloth portion by providing a patella pad inside both ends of the central non-stretchable fabric portion that holds the rubber tube in a stretchable manner. Cut a longitudinal cut in the center stretchable cloth part between the patella pads, and attach a rubber tube exposed part that is not covered with the center non-stretchable cloth part and the end non-stretchable cloth part at both ends of the patella part of the stretchable part. The knee side pads provided at both ends of the non-stretchable cloth part are covered with non-slip cloth, and the knee back pads are provided on the two long and short bands branched from the elastic cloth part and covered with the non-stretchable cloth part, By providing surface fasteners on the inner surface of the end of the two branched long and short bands and the outer surface of the other end of the stretchable fabric, the joint axis of the knee joint and the mechanical axis in wearing walking are matched to prevent displacement and follow the movement.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the invention will be described based on an embodiment with reference to the drawings.
In FIG. 1, when analyzing the walking, when the knee joint is bent from the time of full extension, the knee joint is rotated simultaneously with the sliding of the tibia with respect to the femur. There are two phases, the stance phase and the swing phase, but the stance phase is when the foot is in contact with the floor and 60% is the stance phase, and the swing phase is kicked forward. It accounts for 40% of the time. The knee joint takes a maximum of 65 degrees of flexion during the stance phase of walking and the acceleration phase of the swing phase, and the circumference of the upper patella increases by about 2 cm. Therefore, by wearing walking, the elastic part of the rubber tube exposed part of the force point is tensioned during the separation phase of the stance phase with the patella of the fixed part as a fulcrum, and the lower leg is kicked forward, and the lower leg is accelerated during the swing phase acceleration period The mechanism is that the swinging out accelerates and relaxes during the slow-down phase.
[0016]
【Example】
In FIG. 7, in a state in which the knee is stretched while sitting on a chair, a long cut is provided on the patella, with the long band facing up, and a horizontal cut 14 provided in the longitudinal direction of the stretchable cloth part 1 is applied to the back of the knee. Then, the surface fastener is attached to the side surface of the knee with the surface fastener 11, and similarly, the shorter belt is turned under the back of the knee and attached to the side surface of the knee with the surface fastener 11.
[0017]
By sticking the two long and short bands branched from the stretchable cloth part 1 with the pulling surface fastener 11 slightly stronger, kicking of the lower leg during walking can be strengthened.
[0018]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0019]
A patella pad is provided inside the knee band inside the both ends of the central non-stretchable cloth part that holds the rubber tube in a stretchable manner for the purpose of the fulcrum of the patella, the force point at the time of bending, and the action point at the time of extension. By providing the knee joints at both ends of the patella and applying the restoring force of the rubber tube to the knee joint, it is possible to strengthen the kicking out of the lower leg during walking and to perform active walking support.
[0020]
In addition, the knee band is divided into a fixed portion and a stretchable portion, and the patella portion of the fixed portion is covered with a non-stretchable cloth portion by providing a patella pad inside both ends of the central non-stretchable cloth portion that holds the rubber tube in a stretchable manner. A longitudinal cut is made in the center stretchable cloth part between the patella pads, and a rubber tube exposed part that is not covered with the center non-stretchable cloth part and the end non-stretchable cloth part is stretchably attached to both ends of the patella part of the stretchable part. Cover the knee side pads provided at both ends of the non-stretchable cloth end with a non-slip cloth, and cover the two long and short bands branched from the stretchable cloth part with the knee back pad and cover with the non-stretchable cloth part. The surface fastener is provided on the inner surface of the end of the two long and short belts and the outer surface of the other end of the stretchable cloth, and the rubber tube can be restored by contraction and relaxation of the rubber tube with the patella of the fixed part as a fulcrum by the action of the lever. Enhance the kicking out to the front of the lower leg and accelerate the swing And it has the function of supporting the auxiliary to the promotion of walking the walk.
[0021]
In addition, an active walking promoting function that strengthens the kicking of the lower leg during walking while supporting the knee joint by the action of the pad and the rubber tube by wearing walking, is applied to the knee joint.
[0022]
As a result, the functions of the femoral patellar joint and the quadriceps that constitute the femoral extension mechanism have been improved for patients with weak kicking of the lower leg during walking, i.e., patients with reduced functionality of the femoral extension mechanism. It is possible to support walking in an ideal state that is not present.
[0023]
In addition, it eases painful gait by relieving compression during weight loading in the knee stance phase, so it is easy to walk and work for obese bodies and elderly people suffering from organic diseases of the knee. Walking is possible.
[0024]
In addition, in order to make the fulcrum of the patella effective, patella pads are provided in the dents at both ends of the patella, the knee side pads support the outer and medial collateral ligaments of the femoral tibial joint, and the knee pads pad the band into the back of the knee And there is also an effect to prevent the deviation.
[0025]
In addition, since a lateral cut is made in the longitudinal direction in the central stretchable cloth portion between the patella pads, the pressure on the patella portion when the band is worn can be relieved.
[0026]
And by adopting a pad called artificial muscle, it is quickly deformed and slowly restored to its original shape, so that the shock is absorbed and the pressure is evenly distributed to ease the burden on the soft tissue and ligaments that make up the joint. An attachment such as a spring is not necessary. In addition, even in a sitting position, it can be used without deformation.
[0027]
Further, since the rubber tube has both ends of the rubber tube fixed at the ends of the plurality of non-stretchable cloth portions, the rubber tube is scratched and fixed, so that damage to the rubber can be eliminated.
[0028]
In addition, since the rubber tube exposed portion is stretchably held and provided with a covering band that is annularly covered, direct skin pressure by the rubber tube at the time of wearing can be eliminated, and skin injury such as rash can be alleviated.
[0029]
Also, in order to improve the fit of the knee, the knee is thicker at the top of the patella and thinner at the bottom, so the lower rubber tube of the two rubber tubes is shorter than the upper rubber tube. In addition, the lower band of the two branched bands was set shorter than the upper band.
[0030]
Further, since the two rubber tubes are provided independently on the upper and lower sides, there are advantages such as being adapted to the circumference of each knee and improving the feeling of wearing and the ability to follow movement.
[0031]
And by providing a patella pad inside both ends of a plurality of central non-stretchable cloth parts that elastically hold the rubber tube, and by providing elastic parts (exposed parts) of the rubber tube at both ends of the patella part, By aligning the joint axis with the mechanical axis of the knee band, it is possible to more effectively prevent band displacement and rotation during walking.
[0032]
Further, the thickness (φ) of the rubber tube is selected according to the weight of the user, and the tightening strength of the knee tube and the kicking strength to the front of the leg during walking can be accommodated by adjusting the pulling strength of the rubber tube.
