Description

The invention relates to a belly roller with a double roller structure, in particular an easily replaceable double roller assembly, the application of which can be changed by replacing the rollers.

The abdominal scooter is used to lift the body in the air as the user kneeling on the floor slides the bumper forward and backward. In other words, the user holds the handle with both hands and moves the belly roller back and forth kneeling on the floor to stretch and flex his body, allowing the muscle groups such as abdomen, waist and arms to move. In addition, body weight is used to create training effects. In this way, trunk muscles are trained to achieve movement while achieving a training effect. It takes up little space and can be used when a person lies flat. The belly roller is designed in the form of single, double or multiple roles to choose from.

The modern people are very busy. Space and time for them become narrower and narrower, reducing the time and space for movement. Thanks to its small size, the belly roller is a good choice for the movement, so it can be used directly at home or in a small interior. With the bumpers, the user does not have to go out to training, which reduces the time to go out while the exercise time can be extended. This achieves the effect of sports training whereby the user can use the belly roller for a short time so that it can meet the needs of the sport.

The belly roller is used for fitness and can be used without much space. With this also different muscle groups can be trained at the same time. In addition, the belly roller is often used in the form of single and double roles. Since the abdominal roller in the form of the single role in use is supported on both sides only by means of the center provided in the middle role, it can cause the user tilts due to the uneven distribution of the right and left forces in use. It is more difficult for beginners to keep their balance, which easily disrupts the user's desire to exercise. The belly roller in the form of double roles is indeed more stable than that in the form of single role. Its two ends can be stabilized by the two rollers, so that the user can easily reach the balance when gripping. However, using two rollers to keep the user balanced can not effectively train his or her core muscles, which are used to maintain balance. The two versions have the practical exercise effects, but can not use both effects simultaneously. Although the single roller bungee roller can be used to train the balance between its two ends, its wheel body width is small. Once it is slightly inclined, it is slightly slipped, which can lead to injuries. That's a big disadvantage that needs to be improved.

The invention has for its object to provide a belly roller with a double roller structure, which avoids the above disadvantages by simple measures.

This object is achieved by a belly roller with a dual roller structure having the features specified in claim 1. Further advantageous developments of the invention will become apparent from the dependent claims.

The abdominal roller according to the invention with a double roller structure has the following effects: The abdominal roller according to the invention is used for training and has two rollers with a certain thickness.

Each of the rollers is bounded on the one hand by a first connection surface and on the other hand by a second connection surface. The oblique arc surface of the respective tread region allows the region of the first connection surface to be larger than the region of the second connection surface. In the tread area, a non-slip portion for friction improvement is formed. Each of the rollers is further provided with a shaft bore formed in the center of the roller and passing through both sides thereof. The shaft body is passed through the shaft bore of the rollers. The rollers rotate on the shaft body. The two handles are slid symmetrically on both ends of the shaft body to define a rotation portion in the center of the shaft body, wherein the rollers are positioned in the rotating state in the region of the rotation portion of the shaft body. By the handles, which are pushed onto the shaft body, the two gripping areas for the user's hands for holding are limited. The left / right direction of the rollers can be changed by removing the handles to adjust the manner of use. Therefore, an easily replaceable belly roller is ensured, the application of which can be changed by replacing the rollers.
