Technical Field
[0001] The utility model relates to the technical field of rehabilitation instruments, in particular to a quadriceps femoris strength trainer. Background Art
[0002] The quadriceps femoris is an important structure for straightening the knee joint and maintaining the functional stability of the knee joint. Strengthening the exercise of the quadriceps femoris helps to protect the knee joint. The biomechanical research of the quadriceps femoris shows that during the knee extension process, different angles rely on different muscles. From 0-15°, it mainly relies on the vastus medialis, and from 15-90°, it mainly relies on the rectus femoris and the vastus intermedius, and the four heads have a synergistic effect at each angle. Muscle atrophy of the quadriceps femoris is a common symptom after knee surgery, which will lead to a decrease in the muscle strength around the knee joint and is not conducive to the recovery of knee joint function. The stability of the knee joint depends not only on the support of the knee joint bones, but also on the restriction of ligaments and the quadriceps femoris. Therefore, the functional recovery of the quadriceps femoris is also one of the key points that need to be concerned about after knee surgery.
[0003] In the existing quadriceps femoris training equipment, the training method is single, lacking multi-angle training for the quadriceps femoris, resulting in poor training effects. Therefore, how to make a quadriceps femoris strength trainer to achieve multi-angle training for all muscle bundles of the quadriceps femoris and maximize the training effect of the quadriceps femoris has become an urgent problem to be solved by those skilled in the art.

[0020] As Figures 1 to 2 Shown is a quadriceps strength trainer, which includes a foot pad 1, a foot fixing member 2 arranged on the foot pad 1, a first training component 3 and a second training component 4 respectively connected to the front end and the rear end of the foot pad 1. The first training component 3 includes a string 31 connected to the front end of the foot pad 1 and a holding part 32 connected to the other end of the string 31. The second training component 4 includes an elastic band 41 and a fixing part 42 connected to the other end of the elastic band 41; preferably, the holding part 32 is a pull ring, and the string 31 is inextensible; during use, the foot pad 1 is fixed to the foot of the user who needs to train the quadriceps through the foot fixing member 2 to complete wearing, and the user sits on the seat. This trainer includes three training methods. The first training method is: without using the second training component 4, the user actively pulls the holding part 32 with the hand, the string 31 moves with the holding part 32, and the string 31 drives the user to lift the leg, thereby inducing passive movement of the quadriceps; the second training method is: not pulling the holding part 32 with the hand, simply using the leg strength to do a knee extension action against the elastic band 41, lifting the leg and straightening the leg to induce active movement of the quadriceps; the third training method is: combining the first two training methods, when the leg strength does a knee extension action against the elastic band 41, but the leg strength is not enough to lift the leg and extend the knee, assist by manually pulling the holding part 32, thereby training the quadriceps; thus, combining active training, passive training and the training requirements when the leg strength is insufficient, realizing multi-angle training of all muscle bundles of the quadriceps, and maximizing the training effect of the quadriceps.
[0021] Specifically, the foot mat 1 includes a leg pad 11, a sole pad 12, and a front sole pad 13 that are integrally formed. The angle between the front sole pad 13 and the sole pad 12 is variable. A cord 31 is connected to the front sole pad 13, and an elastic band 41 is connected to the leg pad 11. After the user wears it, when the calf position fits against the leg pad 11, the sole and toe positions fit against the sole pad 12, and the front sole pad 13 fits against the front of the toes. When training is performed by hand, the front sole pad 13 bends, and the front sole pad 13 supports the user's toes, driving the movement of the user's feet and legs.
[0022] Specifically, the foot fixing member 2 includes a first strap 21 fixedly connected to the sole pad 12 and a second strap 22 fixedly connected to the leg pad 11.
