Description

{Multi-Function Sporting Equipment using Elastic}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a multifunctional exercise device, and more particularly, to a multifunctional exercise device using elasticity capable of effectively performing abdominal muscles and upper and lower body movements by a user's simple pushing and pulling using the elasticity of an elastic member.

In general, there are known exercise machines that run on wheels and push and pull by hand. These conventional exercise apparatuses include wheels and knob members that can rotate at the center or both sides of the shaft. The user can perform the slide movement by holding the knob member with both hands and bending the knee or by rolling or pushing the wheel in the kneaded state.

However, such a conventional exercise apparatus requires more force than necessary when the wheel is tilted and pushed, and when the user pushes the exercise device to pull the wheel, the weight of the user causes the wheel to roll forward Which can cause arm and shoulder injuries, and the wheel itself slips to push or pull the wheel, causing the wheel to slip. In addition, since the wheels move in the forward and backward directions only while holding both hands, there is a problem that the function is very monotonous.

1 to 4, a multi-function exercise device 100 using elasticity according to the present invention includes a rod-shaped housing 110 having a receiving space therein, And an elastic member 140 installed on each of the rotary shaft 120 and the rotary shaft 120 and rotatably mounted on the rotary shaft 130 and the rotary shaft 120 to provide a rotary restoring force.

The first and second bearings 150 and 160 are installed at both ends of the housing 110 so as to support and rotate the rotary shaft 120. The first and second bearings 160 and 160 are installed between the first and second bearings 150 and 130, A first fixing frame 170 for fixing one side of the first bearing 150 and the elastic member 140 and a second fixing frame 170 for fixing the other side of the elastic member 140 and fixing the elastic member 140 as the rotation axis 120 rotates A fixing plate 180 for twisting or restoring the elastic member 140, and elasticity adjusting means 190 for adjusting the elasticity of the elastic member 140.

2 and 3, the housing 110 has a shape of a rod-like pipe having an inner space, and has an accommodation space inside the housing 110 to accommodate the components.

A first bearing 150 may be installed at both inner ends of the housing 110 by a first fixing frame 170. The first bearing 150 functions to rotate the rotating shaft 120, and the first bearing 150 may be a general ball bearing. A first bearing 150 may be installed at the center of the housing 110 to prevent the housing 110 from being warped and a second bearing 160 may be further disposed between the housing 110 and the rotating body 130. [ Can be installed. The first bearing 150 installed at the center of the housing 110 and the second bearing 160 installed additionally prevent the housing 110 from being bent by the weight of the user when the user applies force to push and pull the exercise device . The second bearing 160 may preferably be a two-sided bearing.

The rotating shaft 120 may be inserted into the housing 110 through the inner diameter of the first bearing 150 provided at both ends of the housing 110, respectively. The rotation axis 120 may include a first rotation axis 121 and a second rotation axis 122. A rotating body 130 is connected to one side of the first rotating shaft 121 and an insertion hole 123 is formed on the other side. A third bearing 210 can be mounted in the insertion hole 123. The third bearing 210 may preferably be a bushing bearing. The rotary body 130 may be connected to one side of the second rotary shaft 122 and the protruding portion 124 may be formed on the other side of the rotary shaft 122 to be inserted into the insertion hole 123 of the first rotary shaft 121. The first rotary shaft 121 and the second rotary shaft 122 are connected to each other through the third bearing 210 so that the first rotary shaft 121 and the second rotary shaft 122 can have different rotational forces . In other words, since each rotating body 130 installed on both sides of the rotating shaft 120 can have different rotational force by the user, the moving body according to the present invention can be rotated in the forward and backward directions only when pushed or pulled through the rotating body 130 You can also move left and right. Therefore, not only a simple exercise method of pushing and pulling in the forward and backward direction but also a right and left exercise can be performed, so that the utilization of exercise is high and a balanced physical exercise can be performed.

Rotors 130 capable of moving the exercise device 100 may be connected to both ends of the rotary shaft 120, respectively. As the rotating body 130 rotates and moves, the user can push and move the exercise device 100 against the floor. The rotating body 130 may be a general wheel. The outer surface of the wheel is preferably formed of a rubber material so as to increase the frictional force with the floor to prevent the wheels from slipping during the exercise and to reduce the noise generated when the exercise device is pushed against the floor, Interlayer noise can be prevented when exercising indoors. A 'V' groove or a 'W' groove may be formed in the rubber material to increase the frictional force when the user pushes the exercise device on the floor and reduce the friction force when pulled to minimize slippage during repeated movement.

As shown in FIG. 4, the dumbbell spindle 310 can be additionally mounted through the mounting hole 131 formed at the center of the side surface of the rotating body 130, and can also be used as a sports machine for arm movement like a dumbbell.

The elastic member 140 may be disposed on both sides of the axis 110 of the housing 110 as shown in FIG. The resilient member 140 may preferably be a spiral spring. One end of the elastic member 140 may be fixed to the first fixing frame 170 and the other end of the elastic member 140 may be fixed to the fixing plate 180 provided on the rotary shaft 120. In addition, the elastic members 140 may be installed so that the directions in which the elastic members 140 are wound around the axis of symmetry A of the housing 110 are opposite to each other. By providing the elastic members 140 in opposite directions to each other, it is possible to smoothly balance the mechanical force when pushing and pulling the exercise device.

The other side of the elastic member 140 is fixed to one side of the fixing plate 180 and is installed in the guide groove 125 formed on the rotation axis 120 so that the other side of the elastic member 140 can rotate together when the rotation axis 120 rotates . Since the elastic member 140 is fixed to the first fixing frame 170 and the other side is fixed to the fixing plate 180, the elastic member 140 fixed to the fixing plate 180 when the rotation shaft 120 is rotated And can be twisted or restored according to the rotating direction of the fixing plate 180. That is, when the user pushes the exercising apparatus 100 according to the present invention by applying force to the floor, the rotating body 130 rotates in the direction of the pushing force of the user and the rotating shaft 120 connected to the rotating body 130, And the fixing plate 180 rotate together with the rotating body 130 in the same direction. Accordingly, the fixing plate 180 is twisted while twisting the elastic member 140 while rotating.

When the user pulls the rotating body 130, the rotating body 130 rotates in a pulling direction and the rotating shaft 120 and the fixed plate 180 connected to the rotating body 130 rotate together with the rotating body 130 in the same direction. In addition, the resilient member 140, which is twisted while being twisted, generates a restoring force of the resilient member 140 to be unwound, and the rotating body 130 naturally returns in the pulling direction. Therefore, when the user pushes the exercise apparatus according to the present invention, the user pushes the exercise apparatus using the force of the body. When the user pulls the exercise apparatus according to the present invention, the user can pull the exercise apparatus with a small force owing to the restoring force of the elastic member 140, It is possible to solve the problems that arise when pulling.

The multifunctional exercising apparatus 100 using elasticity according to the present invention may further include elasticity adjusting means 190 capable of adjusting the elasticity of the elastic member 140. The elasticity adjusting means 190 is disposed on the rotating shaft 120 and attached to the female screw 191 and the fixing plate 180 having screw grooves formed on the inner surface thereof. (192) may be included.

In addition, gear-shaped protrusions 193 are formed on one surface of the female screw 191 and the engagement protrusions 126 of the rotation shaft 120 and can be engaged with each other. When the elastic member 140 is compressed or relaxed in order to adjust the elasticity of the elastic member 140 by rotating the female screw 191 by the protrusion 193, the female screw 191 is elastically deformed by the elasticity of the elastic member 140 And can be prevented from returning.

One end of the male screw 192 is attached to the fixing plate 180 and is disposed in the guide groove 125 of the rotation shaft 120 so as to rotate together with the rotation shaft 120 when the rotation shaft 120 rotates. The male screw 192 is engaged with the screw groove of the female screw 191 and can be moved laterally when the female screw 191 is rotated. The fixing plate 180 connected to the male screw 192 can be moved in the same direction as that of the male screw 192 as the male screw 192 is moved to the left or right and the fixing plate 180 can be moved The elasticity of the elastic member 140 can be adjusted. The user manually rotates the female screw 191 through the adjusting groove 111 formed outside the housing 110 to move the male screw 192 to the left or right to adjust the elasticity of the elastic member 140, The elastic member 140 can be squeezed or loosened so that elastic movement can be performed for each user. Further, between the intervals of the respective elastic members 140, an auxiliary elastic member 220 may be further provided to reinforce the elasticity. The user further includes the auxiliary elastic member 220 in the elastic member 140 so that when the elastic member 140 itself is relaxed due to long-term use of the exercise device or when it is desired to exercise using greater elasticity, The elastic force of the elastic member 140 can be adjusted by providing the auxiliary elastic member 220 to the user. Further, since the auxiliary elastic member 220 is further provided, the elasticity of the elastic member 140 is increased, so that the elasticity adjusting means 190 can effectively control the elasticity.

2, since the elastic member 140 and the elasticity adjusting means 190 are installed symmetrically about the axis of symmetry A of the housing 110 as shown in FIG. 2, The rotational force of the rotating body 130 on the right side and the rotational force of the rotating body 130 on the right side can be changed so that the user can move the present exercise device in a desired direction when pushing or pulling the exercise device.
