Description

Technical Field

[0001] The present invention relates to the technical field of flexibility training, and in particular to a progressive stretching device for flexibility training. Background Art

[0002] In the field of flexibility training, the split is one of the common training items, which plays an important role in stretching the lower limb ligaments and improving muscle flexibility. At present, there are mainly two types of split training equipment on the market: the hanging rope type training device and the mechanical split trainer. However, the existing technology has obvious limitations in practical applications: the traditional hanging rope training method requires one end of the rope to be fixed to the ankle of the trainer, and the other end to pass through an external hook and be pulled by both hands. The leg is forced to lift by manually pulling the rope to achieve stretching. However, this method has the following problems: 1. Since both hands need to continuously pull the rope during the training process, it is impossible to use the wall or other supports to maintain balance. At this time, combined with the unstable center of gravity when standing on one leg, it is very easy to cause the trainer to fall or cause ligament strain due to sudden imbalance. 2. This training depends on an external fixed point (such as a hook), which limits the flexibility of the training scenario, and it is difficult to accurately control the rope length and tension.

[0056] The working principle and usage process of the present invention:

[0057] In the use state:

[0058] When doing splits training, first, the trainer adjusts the position of the sleeve rod 413 inside the sleeve 412 according to their own leg length. When adjusting, first rotate the locking bolt 417. The locking bolt 417 drives the contact piece 418 to move. When the contact piece 418 is no longer in contact with one side of the sleeve rod 413, the sleeve rod 413 can be moved so that the sleeve rod 413 is in different positions inside the sleeve 412 to adapt to people of different heights.

[0059] During the exercise, the person first sits on the seat 1, places the legs on the sleeve 412 and the sleeve rod 413, and makes the calf position inside the U-shaped block 415. At the same time, the sole of the foot contacts one side of the swing plate 443. Then, use the strap 444 to cooperate with the hook-and-loop fastener surface 446 and the hook-and-loop fastener pile surface 445 to fix the foot to the swing plate 443. At this time, the restraint of one leg is completed, and the other leg is restrained on the second training component 5. Then, the trainer rotates the first rotating rod 2 according to the training intensity. The first rotating rod 2 drives the transmission rod 3 to rotate. When the transmission rod 3 rotates, it will drive the first training component 4 and the second training component 5 to move in two different directions respectively, so that the two legs are opened to form a split.

[0060] When doing splits training, the trainer can also lean forward to do lower back training.

[0061] When doing splits training, the trainer can also train the ankles. During the training, first, the person holds one end of the pull rope 447. At this time, the person's toes tilt forward, which can drive the swing plate 443 to tilt forward. When the swing plate 443 tilts forward, it will drive the swing shaft 442 and the angle gear 448 to rotate. When the angle gear 448 rotates, it drives the angle rack 449 to move, so that the angle rack 449 squeezes the angle damping rod 4410, increasing the training intensity for the person. When the swing plate 443 rotates, it will also drive the pull rope 447 to move. At this time, if the pull rope 447 is pulled forcefully, the training intensity of the toes and ankles will be increased. At the same time, the pulling of the pull rope 447 will also make the toes tilt towards the face, thus realizing the training of the ankles in different directions.

[0062] When doing splits training, the neck can also be trained. During the training, first, the person puts the cloth strip 66 around the lower jaw. Then, rotate the adjusting rod 68. When the adjusting rod 67 rotates, it will drive the transmission shaft 68 to rotate, thus driving the lifting screw rod 63 to rotate. When the lifting screw rod 63 rotates, it will drive the lifting rod 64 and the suspension rope 65 to move upward. When the suspension rope 65 moves upward, it will drive the cloth strip 66 to move upward, thus realizing the training of the neck.

[0063] When it is necessary to perform the shoulder-opening, backbend, and leg-lifting training, first, the staff removes the resistance component 422 from the socket 421. When removing it, first, press the U-shaped insertion rod 4222. The U-shaped insertion rod 4222 will drive the reset damping rod 4223 to move, causing the reset damping rod 4223 to be squeezed. At this time, one end of the U-shaped insertion rod 4222 disengages from the locking hole 423. After disengagement, the entire resistance component 422 is removed from the socket 421. After removal, at this time, it is inserted into the corresponding height hole 435. After insertion, release the U-shaped insertion rod 4222, so that one end of the U-shaped insertion rod 4222 is inserted into the fixing hole 436 under the action of the reset damping rod 4223, thus completing the reinstallation of the resistance component 422; after reinstallation, at this time, rotate the first rotating rod 2, so that the first training component 4 and the second training component 5 are in a horizontal state. At the same time, the two resistance components 422 face each other to form a rod shape;

[0064] At this time, the trainee sits on the seat 1 with the legs together and places the legs on the protection column 4224. At this time, there is a certain inclination angle between the legs and the body. At this time, the person bends downwards so that the face touches the legs, thus completing the training of the person's shoulders, waist, and legs;

[0065] When the trainee needs to train the split stance in a standing position later, first, adjust the stretching component 7. When adjusting, first, pull the cylinder 74 so that one end of the cylinder 74 disengages from the round hole 71. At the same time, the cylinder 74 will stretch the locking damping rod 73. When the cylinder 74 disengages, at this time, the U-shaped rod 72 can be moved so that the U-shaped rod 72 is at different positions on the column 61. Then, make the cylinder 74 re-insert into the corresponding round hole 71. After adjustment, the positions of the long rod 77 and the waistband 78 are also adjusted. At this time, the trainee stands on one leg on the ground and makes the other leg rest on the long rod 76, thus realizing the split stance in a standing position on one leg;

[0066] When it is necessary to perform the backbend training, the person faces the column 61. Then, place the waistband 78 around the waist, and then tilt the head backward so that the waist sinks backward, thus completing the backbend training.
