Description

The present invention relates to an exercise roller, and particularly to a stopper structure of an exercise roller having an automatic safety guard function.

Conventional exercise rollers include rollers and grip bars that penetrate the rollers. The roller rotates according to the grip bar, grips the grip bar with both hands when exercising, and supports the roller against the ground, and further moves the roller back and forth within the reciprocating range. Achieve the purpose of exercise or strength training by moving the position. However, if you look closely at the above-mentioned conventional structure, you can see that there are still some deficiencies. The main reason is that the exercise roller does not have a stopper function, and when the user makes a mistake in the limit of physical strength or operation, the user cannot push out or pull back the roller smoothly, so the user momentarily And fall. It is a drawback of conventional exercise rollers that the user is not only mentally stressed during use, but can also seriously injure muscles.
Therefore, the present inventor has obtained the present invention full of practicality as a result of detailed design and careful evaluation of the above-mentioned goals based on many years of experience in manufacturing development and design of related products.

It solves the above-mentioned drawbacks in the present technology and provides an exercise roller stopper structure.

In the stopper structure of the exercise roller of the present invention, grips are formed at both ends of the round bar, at least one roller is pivotally installed between the two grips of the round bar, and at least one stopper member is in the center. A passage hole is provided, the stopper member is fixed to the round bar by the passage hole, the front stop arm extends toward one end of the stopper member, and the rear stop arm extends toward the other end of the stopper member. Stretched, the length of the front stop arm and the rear stop arm are all longer than the radius of the roller.

A through hole is provided in the middle stage of the round bar, and a screw hole is provided in the stopper member, the screw hole is connected to the passing hole, and the screw hole and the through hole are combined to tighten the screw rod. ..

The number of the rollers is two, and the stopper member is located between the two rollers.

The stopper member is made of a plastic material.

The front stop arm and the rear stop arm form an arc shape with each other.

Anti-slip members are fixed to the ends of the front stop arm and the rear stop arm, respectively.

The main object of the present invention is that when the roller is pushed too far, the user's arm is taken and moved downward to rotate the round bar and further stop after the stopper member. When the arm is interlocked to hit the ground, it prohibits the roller from continuing to be pushed. When the roller is pulled back too close, the user's arm is taken and moved upwards to rotate the round bar and further interlock the front stop arm of the stopper member to hit the ground. Then, it is prohibited that the roller continues to be pulled back. When the user exceeds the limit of physical strength or the reciprocating range suitable for exercise, it is not necessary to stop the movement of exercise by himself, and the best safety guard effect is achieved.

FIG. 8 is a diagram showing a state in which the present invention is pulled back to a place where it is too close.

First, see FIGS. 1 and 2. The stopper structure of the exercise roller of the present invention includes a round bar 10, at least one roller 20, and at least one stopper structure 30. Grips 11 are formed at both ends of the round bar 10, and through holes 12 are provided in the middle of the round bar 10. At least one roller 20 is pivotally installed between the two grips 11 of the round bar 10, the number of the rollers 20 is two, and the stopper member 30 is located between the two rollers 20. At least one stopper member 30 is made of a plastic material, a passage hole 31 is provided in the center of the stopper member 30, and the stopper member 30 is fixed to the round bar 10 by the passage hole 31, and further, the stopper The member 30 is provided with a screw hole 32, the screw hole 32 is connected to the passage hole 31, and the screw hole 32 and the through hole 12 are combined and the screw rod 33 is tightened. The front stop arm 34 extends toward one end of the stopper member 30, the rear stop arm 35 extends toward the other end of the stopper member 30, and the front stop arm 34 and the rear stop arm 35 are circular to each other. It has an arc shape, and the lengths of the front stop arm 34 and the rear stop arm 35 are all longer than the radius of the roller 20, and anti-slip members 36 are fixed to the ends of the front stop arm 34 and the rear stop arm 35, respectively. Will be done.
For the combination of structures, refer to FIGS. 1 to 4 continuously. The round bar 10 is bored in the passage hole 31 of the stopper member 30, so that the screw hole 32 of the stopper member 30 is exactly aligned with the through hole 12, and the screw hole 32 is further aligned with the screw hole 32. The round bar 10 and the stopper member 30 are integrally fixed by being tightened into the through hole 12. Further, when both rollers 20 are fitted to the round bar 10, both rollers 20 are applied after the stopper member 30, and by fitting the grip 11 to the outside of the round bar 10, the roller 20 is fitted to the round bar. The axis is restricted to rotate only in the 10 position-limited places.

Please refer to FIG. 2 for the actual effect of use in accordance with FIGS. 5 and 6. When the user grips both grips 11 with both hands, the roller 20 touches the ground, the front stop arm 34 of the stopper member 30 faces the front of the user, and the rear stop arm 35 faces the rear of the user. The user can achieve the effects of exercise and muscle training by pushing the roller 20 back and forth while supporting the body in a kneeling or toe-like manner. See also FIGS. 7 and 8. When the user makes a mistake in the limit of physical strength or operation, the rolling force of the roller 20 is exceeded in a suitable reciprocating range, and when the reciprocating range of rolling is exceeded, the roller 20 is difficult to push or pull back by the force. May injure muscles. In the present invention, when the roller 20 is pushed to a position too far, the user's arm is taken and moved downward to rotate the round bar 10, and further, the rear stop arm 35 of the stopper member 30. When interlocked so as to hit the ground, the roller 20 is prohibited from being continuously pushed. When the roller 20 is pulled back too close, the user's arm is taken and moved upwards to rotate the round bar 10 and further bring the front stop moving shoulder 34 of the stopper member 30 to the ground. When interlocked to hit, the roller 20 is prohibited from continuing to be pulled back. Summarizing the above, when the user exceeds the limit of physical strength or the reciprocating range suitable for exercise, it is not necessary to stop the movement of exercise by himself, and the best safety guard effect is achieved. That is, when the user needs to stop exercising, the round bar 10 is driven to rotate and the stopper member 30 is brought into contact with the ground to exert a stopper effect.
Since the above is only a part of the examples according to the present invention, the scope of implementation of the present invention is not limited. That is, changes, modifications, etc. made within the claims of the present invention should also belong to the scope of the present invention.
