Abstract

The invention belongs to the field of sports appliances and relates to a waist twisting training aids with pendulums. The function of the waist twisting training aids is to train muscle strength and neuromuscular coordination of the waist. The waist twisting training aids consists of a main shaft with an arc structure, waist fixing forks, the pendulums and pendulum connection bars. The main shaft with the arc structure is composed of two sections of hollow pipes arranged on the same straight line; the inner sides of the main shaft can be inserted into the waist fixing forks; and the outer sides of the main shaft can be inserted into the pendulum connection bars. The waist fixing forks are matched with bolt screws on the main shaft, so that the waist fixing forks can tightly press the waist to fix the training aids on the waist. Each pendulum is composed of a pendulum piece, screws for fixing the pendulum piece, and a screw rod. The inertia force generated by the rotation of each pendulum is transferred by a subshaft to the main shaft, and then the main shaft is transferred by the waist fixing forks to the waist of a human body. When the human body twists the waist to rotate the pendulums, the effects of inertia force are also exerted. The waist twisting training aids is provided with a special bracket consisting of vertical bars, lifting slide bars and a cross bar, and the waist twisting training aids is placed on the bracket.

Description

Waist twist trainer with pendulum

technical field

The invention belongs to the field of sports equipment and relates to a waist twisting trainer with a pendulum, which functions to train the muscle strength of the waist and the coordination ability of the nerves and muscles of the waist.

Background technique

Invention patent "dumbbell with adjustable inertial resistance load characteristics" (Patent No. ZL200810042366.X) has a structural feature that there is a rotatable pendulum inside the dumbbell. When the user moves the dumbbell up and down, only when the period and intensity of force are appropriate , to make the pendulum rotate. When the pendulum in the dumbbell rotates, a periodic inertial force is generated, which makes the user's arm and whole body generate additional periodic vibrations. In order to adapt to this periodic vibration, the muscles of the whole body generate periodic muscle tension. , There are also some training effects on the muscle strength of the whole body. This inertial force is a resistance load, so it is called a dumbbell with inertial resistance load characteristics. Invention patent "A Handheld Vibrator" (Patent No. ZL200910053036.5) Its structural feature is that there is an eccentric balance wheel inside the vibrator, and the reciprocating motion of the vibrator wrench is transmitted to the eccentric balance wheel shaft to become rotation, and the eccentric balance wheel shaft drives The eccentric balance wheel rotates to generate vibration, which generates vibration while pulling the wrench with the hand to train the grip strength, which makes the wrist joint and forearm vibrate, and relieves the fatigue of the wrist.

The structural feature of the above two invention patents is that there is a pendulum or eccentric balance wheel rotating around the axis. The functional feature is that when the pendulum or eccentric balance wheel rotates, there is a force on the rotating shaft. When holding the above-mentioned invention As with dumbbells or vibrators, the hand interacts with such a force that exercises the associated muscles.

If the force on the rotating shaft caused by the rotation of the pendulum can directly act on the waist of the human body through a certain mechanical structure, it will be beneficial to the muscle strength of the human waist and the coordination ability of the neuromuscular muscles of the waist.

Contents of the invention

The invention provides a waist twisting training device with a pendulum. The force on the rotating shaft caused by the rotation of the pendulum can directly act on the waist of the human body through the transmission of some mechanical structures.

The structure of the present invention mainly consists of the following parts.

1. Torsion trainer spindle with curved structure. the

2. Waist fixing fork.

3. pendulum.

4. T-shaped pendulum connecting rod.

5. Dedicated stand.

The structural feature of the present invention is that the middle of the main shaft of the training device is connected by an arc structure, and the waist of a person is in the middle of the main shaft. The waist fixed fork is inserted into the inner side of the main shaft, and the T-shaped pendulum connecting rod is inserted into the outer side of the main shaft. The "horizontal" bar of the T-shaped pendulum connecting rod is called the auxiliary shaft. There are two fixing methods for the T-shaped pendulum connecting rod and the main shaft. One fixing method makes the auxiliary shaft perpendicular to the ground, and the pendulum rotates around the auxiliary shaft in the horizontal plane; the other fixing method makes the auxiliary shaft parallel to the ground, and the pendulum rotates in the horizontal plane The frontal plane (the plane perpendicular to the horizontal plane and parallel to the human face) rotates around the minor axis. The inertial force caused by the pendulum rotating around the rotatable shaft in the sub-shaft is transmitted to the main shaft through the sub-shaft, and the main shaft is transmitted to the waist of the human body through the waist fixing fork. When the human body twists the waist to make the pendulum rotate, it is simultaneously affected by the inertial force, which will benefit the muscle strength of the human waist and the coordination ability of the neuromuscular muscles of the waist.
