Description

  The present invention relates to an abdominal muscle roller, and in particular, a spiral spring assists the user to pull back the wheel, reduces the occurrence of sports obstacles and increases safety, and prevents the spiral spring from being deformed or damaged. The present invention relates to an abdominal muscle roller that is highly practical because it can control the winding operation of the spiral spring and prevent the generation of noise when the spiral spring is used.

  In modern society, life rhythm is fast and people's lives are very busy, so it is easy to feel mental stress from various pressures, so it is important to eliminate stress in a timely manner. As a result, many people are physically and mentally relaxed by doing a variety of exercises so that they can change their minds while working and continue to challenge bigger things in the future. Decreasing the amount of fat in the body to increase metabolism and improve blood circulation can greatly help the health of the body.

  In general, the abdominal muscle roller often seen in various exercise assisting equipment has a shaft attached to the wheel, and handles on both sides of the shaft attached to the outside of the wheel. The user can train by holding the handle, bringing the wheel into contact with the ground, and performing a reciprocating operation in which the user pushes the wheel forward and then pulls it back.

  However, the abdominal muscle roller described above can achieve the expected effect that the user trains the body, but the structure is provided with a structure that assists in pulling back, as can be seen in actual use. Therefore, when the user pushes the wheel forward, if the user does not have enough force to push or pull the wheel, or if the user does not have enough force to reciprocate the wheel, There is a risk that a person may fall or injure in the worst case, there is a certain degree of danger in use, and there is still room for improvement in the overall structure.

  In view of such a current situation, the present inventor completed the abdominal muscle roller of the present invention as a result of intensive studies.

  The purpose of the present invention is to assist the user by pulling the wheel back with a spiral spring, to reduce the occurrence of sports obstacles and improve safety, and to prevent the spiral spring from being deformed or damaged. It is an object to provide an abdominal muscle roller that controls the entrainment operation and prevents the generation of noise when using a spiral spring and is highly practical.

  In order to solve the above-described problem, according to the first aspect of the present invention, there is provided an abdominal muscle roller including a wheel, a shaft member, and a spiral spring, and the wheel is constituted by two rollers, and the two rollers are mutually connected. An accommodation space is formed inside the wheel, and the shaft member is inserted into a central portion of the wheel and pivotally attached to the wheel, and the wheel is disposed at both ends of the shaft member. A handle is attached to the outside of the spiral spring, and the spiral spring is disposed in the receiving space with the shaft member as an axis, and one end is connected and fixed to the receiving space and the other end is connected and fixed to the shaft member An abdominal muscle roller is provided, wherein a position restraining ring is provided on the outer edge.

  It is preferable that a direction indication mark is provided on the outer edge of the wheel in the winding direction of the spiral spring.

  It is preferable that the wheel is screwed through a screwing member, and a silencer washer is fitted to an outer edge of the screwing member.

It is a disassembled perspective view which shows the abdominal muscle roller which concerns on one Embodiment of this invention. It is a perspective view which shows the abdominal muscle roller which concerns on one Embodiment of this invention. It is assembly sectional drawing which shows the abdominal muscle roller which concerns on one Embodiment of this invention. It is explanatory drawing of the use condition of the abdominal muscle roller which concerns on one Embodiment of this invention.

  In order to more fully and clearly disclose the technical means of the present invention and the effects achievable thereby, the present invention is described in detail below in conjunction with the accompanying drawings and reference numerals disclosed.

First, reference will be made to FIGS. FIG. 1 is an exploded perspective view showing an abdominal muscle roller according to an embodiment of the present invention. FIG. 2 is a perspective view showing an abdominal muscle roller according to an embodiment of the present invention. FIG. 3 is an assembled cross-sectional view illustrating an abdominal muscle roller according to an embodiment of the present invention.
As shown in FIGS. 1 to 3, the abdominal muscle roller according to one embodiment of the present invention is composed of at least a wheel 1, a shaft member 2, and a spiral spring 3.

The wheel 1 is composed of two rollers, and the two rollers are fixed to each other. The wheel 1 is screwed through a screwing member 11, and a silencer washer 111 is fitted to the outer edge of the screwing member 11. An accommodation space 12 is formed inside the wheel 1, the shaft member 2 is inserted in the center of the wheel 1, and the shaft member 2 is pivotally attached to the wheel 1. Handles 21 are attached to both ends of the shaft member 2 outside the wheel 1. The spiral spring 3 is disposed in the accommodation space 12 with the shaft member 2 as an axis.
One end of the spiral spring 3 is connected and fixed to the housing space 12, the other end is connected and fixed to the shaft member 2, and a position restricting ring 31 is provided on the outer edge. The position restricting ring 31 protects the spiral spring 3 and restricts position. Thus, the spiral spring 3 is prevented from being deformed or damaged. A direction indication mark 13 is provided on the outer edge of the wheel 1 in the winding direction of the spiral spring 3.

When the present invention is actually used, the user stands or sits down and grasps the handle 21 attached to both ends of the shaft member 2 with both hands to bring the wheel 1 into contact with the ground. It can be pushed in the direction indicated by the direction indication mark 13. When the wheel 1 is pushed, the spiral spring 3 is gradually wound with the rotation of the wheel 1 (refer also to FIG. 4), and when the user pulls the wheel 1 back, the spiral spring 3 recovers by the recovery elasticity of the user. Can easily pull back the wheel 1 and prevent a user from having a sports injury.
When the spiral spring 3 is used, the silencing washer 111 is fitted to the outer edge of the screwing member 11 screwed to the wheel 1, and the silencing washer 111 separates the spiral spring 3 from the screwing member 11. The spiral spring 3 and the screwing member 11 can be prevented from coming into contact with each other and generating abnormal noise. Further, a position restraining ring 31 is provided on the outer edge of the spiral spring 3 to prevent the position restraining ring 31 from positioning and removing the spiral spring 3 correctly, and noise is generated when the spiral spring 3 is operated. To prevent.

As can be seen from the above, the abdominal muscle roller of the present invention has the following advantages (1) and (2) as compared with the prior art.
(1) The spiral spring is disposed in the housing space with the shaft member as an axis, and when the user pulls back the wheel, the recovery elasticity of the spiral spring is used to cause a sports obstacle when the user pulls the wheel back. So that it can be used safely.
(2) A position restraining ring is provided on the outer edge of the spiral spring. The position restraining ring protects the spiral spring and restrains the position to prevent the spiral spring from being deformed or damaged. Therefore, when the spiral spring is used, it is possible to prevent the rotational position of the wheel from shifting and noise from being generated.
