Description

A kind of inertial dumbbell with rolling guide

technical field

The invention belongs to the field of sports equipment and relates to an improved dumbbell, which has the function of training the coordination ability of muscles of the whole body while training the arm strength. the

Background technique

Modern people are increasingly aware of their health and love various fitness exercises, but many exercises are limited by time and space. Dumbbells are small in size, and users do not need to take up too much space when moving. Lifting dumbbells is not limited by time and space, and is a very convenient exercise that is beneficial to health. the

Lifting dumbbells is performed by users holding dumbbells with their arms to complete arm flexion, extension or other whole-body exercises, which can train muscle strength. But lifting dumbbells also has its shortcomings. Lifting dumbbells is mainly strength training, but not enough for neuromuscular coordination training. In order to increase the function of training muscle coordination, traditional dumbbells need to be improved. the

Invention Patent No. 200810042366X "Dumbbells with Adjustable Inertial Resistance Load Characteristics" has a structural feature that there is a rotatable eccentric pendulum inside the dumbbell. When the user moves the dumbbell up and down, only when the period and intensity of force are appropriate can the eccentric Pendulum spins. The dumbbell without this structure has no limitation on the strength and cycle when moving, so the requirement for neuromuscular coordination in motion is not high. When moving the dumbbell of the present invention, there are requirements on the cycle and intensity of exertion. When the eccentric pendulum in the dumbbell rotates, a periodic inertial force is generated, which causes additional periodic vibrations in the user's arms and the whole body. In order to adapt to this periodic vibration, the muscles of the whole body produce periodic muscle tension. , It also has some training effects on the muscle strength of the whole body. the

Contents of the invention

The structure of the present invention includes a hand-held shaft, a rolling guide rail, a rolling ball and a support bar. The rolling guide rail is bent into an annular shape by a hollow circular tube, and the cross-section shape of the hollow circular tube for making the rolling guide rail is annular, and one or more rolling balls are placed in the hollow circular tube, and the rolling guide rail is located on the circular rolling guide rail. The inner side of the guide rail has a window for putting the rolling ball into the rolling guide rail or taking out the rolling ball from the rolling guide rail, and a sliding cover is arranged on the window to open or close the window. The rolling ball is placed in the rolling guide rail, and one or several identical or different rolling balls can be placed, and the size of the rolling ball can be any size ball smaller than the inner diameter of the rolling guide rail. The support bar is connected with the rolling guide rail and the handle shaft. A further description of each part follows. the

1. Handshaft (1): The handshaft (1) can be made of metal or non-metallic plastic or rubber. If it is made of metal, the surface of the handshaft (1) is covered with non-metallic plastic or rubber. Improve the feeling when holding the shaft (1) with your hand. The inside of the handle shaft (1) is a solid structure or a hollow structure, and the hollow structure can reduce weight. the

2. Rolling guide rail (2): The rolling guide rail (2) is bent into a ring shape by a hollow circular tube. The shape of the cross-section of the hollow tube making the rolling guide (2) is circular. One or more rolling balls (3) are placed in the hollow tube. A window (4) is provided on the rolling guide rail (2) for putting the rolling ball (3) into the rolling guide rail (2) or taking out the rolling ball (3) from the rolling guide rail (2). The window (4) has a sliding cover (5) to open or close the window (4). The window (4) is located on the inner side of the circular rolling guide (2). When the rolling ball (3) rolls in the rolling guide (2), due to the effect of centrifugal force, the circle between the rolling ball (3) and the rolling guide (2) will The outer side of the cavity is in contact, so opening the window (4) on the inner side of the annular rolling guide (2) will not affect the rolling of the rolling ball (3) in the rolling guide (2). the

The material of making the hollow tube of rolling guide (2) can be metal material, also can be plastic material. the

The surface of the metal hollow tube used to make the rolling guide (2) can have many small holes, the diameter of which is less than one-tenth of the rolling ball, and people can see the rolling ball (3) rolling in the rolling guide (2) . the

The hollow tube that makes rolling guide (2) can be single color, also can be various colors. the

The hollow tube for making the rolling guide (2) can be made of opaque material, translucent material, or transparent material. The translucent material or transparent material can observe the rolling of the rolling ball (3) in the rolling guide rail (2). the

3. Rolling ball (3): The rolling ball (3) is placed in the rolling guide rail (2), and one or several identical or different rolling balls (3) can be placed in the pipeline. The size of the rolling ball (3) can be a ball of any size smaller than the inner diameter of the rolling guide rail (2). the

The rolling ball (3) can be a hollow metal ball or a hollow non-metallic ball, and is light in weight. It can also be a solid metal ball or a solid non-metal ball with a certain weight. the

The surface of the rolling ball (3) can have different colors and decorative patterns. the

A metal tuning fork can be arranged in the hollow rolling ball (3), and the metal tuning fork makes a sound when the ball rolls. the

4. Support bar (6): The support bar (6) connects the rolling guide rail (2) and the handle shaft (1). the

Compared with ordinary dumbbells, the dumbbell structure of the present invention is characterized in that there are two rolling guide rails (2) in the dumbbell, and one or several rolling balls (3) are arranged in the rolling guide rails (2). The structural features determine the functional features of the present invention. When holding the dumbbell of the present invention, the movement mode is slightly different from that of common dumbbells. The handle shaft (1) of the dumbbell of the present invention is moved in an approximate circle, and the rolling ball (3) will roll along the rolling guide rail (2). The inner wall of the guide rail (2) rolls, and the rolling ball (3) generates an inertial force. The human body feels this inertial force, and the coordinated movement of muscles can make the rolling ball (3) continuously roll in the rolling guide rail (2). the

Compared with ordinary dumbbells, moving ordinary dumbbells does not need a learning process and can be moved directly, and moving the dumbbells of the present invention will have a short learning process. The movement of ordinary dumbbells is mainly arm movement, the front and back swing of the chest and abdomen is not obvious, and there is almost no up and down movement of the chest and abdomen. The dumbbell of the present invention moves all over the body, the chest and abdomen swing back and forth and has up and down movements, and the knee joints also have small changes, indicating that the movement itself Embodiments require coordinated movement of the whole body. the
