Abstract

The present invention relates to a two-dimensional treadmill using a lateral omniball. More specifically, the present invention relates to a two-dimensional treadmill using a lateral omniball, which circulates a tread part along an X-axis and a Y-axis, and moves in omnidirection by taking control of circulation speed. To this end, a Y-axis driving part which circulates the tread part along the Y-axis is produced in a form of a plurality of omniballs, and supplies power for Y-axis circulation by allowing the Y-axis driving part to touch an outer lateral side of the tread in the tread part.

Description

[0001] The present invention relates to a two-dimensional treadmill using a side omni ball,

The present invention relates to a two-dimensional treadmill using a lateral omnidirectional ball, and more particularly to a two-dimensional treadmill that circulates the tread in the X-axis direction and the Y-axis direction, A Y-axis sole portion for circulating the tread portion in the Y-axis direction is formed of a plurality of omni balls, and a power for circulation in the Y-axis direction is transmitted so as to be in contact with the outer surface of the tread in the Y- Dimensional treadmill using a side omnidirectional ball.

Treadmill is one of the ergometers, and is called Motor Driven Treadmill.

The treadmill is mainly used as a belt that moves in a certain direction by the power. It is used for the measurement of the whole body endurance, the function test of the cardiovascular system, and the training. The pedestrian walks or runs on the belt according to the moving speed of the belt.

The treadmill can be classified into a one-dimensional or two-dimensional treadmill according to the moving direction. The one-dimensional treadmill is a simulation device capable of forward and backward unidirectional movement. It is mainly used for treadmills for.

Unlike one-dimensional treadmill, which can move forward and backward unidirectionally, the two-dimensional treadmill is a simulation device capable of forward, backward, left, and rightward 360-degree forward movement and is used for a virtual reality simulator As well as soldiers' combat training, virtual tour, fire safety training and so on.

That is, the two-dimensional treadmill has the advantage of being used in various simulators because it is possible to naturally walk in all directions in one space.

Generally, a two-dimensional treadmill is constituted by connecting a unit body rotatable in the Y-axis direction in parallel in the X-axis direction to form a tread portion and rotating the tread portion in the X-axis direction or the Y- Can be generated.

In this case, in the conventional two-dimensional treadmill, rotational motion in the X-axis direction is generally performed by fastening the chain to transmit power, and in the case of rotation in the Y-axis direction, a motor is mounted inside the tread portion, Or a method of indirectly transmitting power by providing a driving unit for providing frictional force inside the tread portion can be used.

A method of indirectly delivering power by providing a drive for providing a frictional force to the tread portion is disclosed in U.S. Patent No. 7780573 ("Omni-directional Treadmill with Applications").

However, the method of generating and transmitting the self-generated power by mounting the motor in the tread portion described above has a disadvantage in that acceleration and deceleration in the X-axis direction is disadvantageous due to an increase in the total weight of the tread portion.

In addition, in the method of indirectly transmitting the power by providing the driving part for providing the frictional force to the tread part, there is an advantage that the weight of the tread part is light. On the other hand, when the power is transmitted, There is a problem that can not be achieved.

The.

A two-dimensional treadmill (1000) using a side omni-ball according to the present invention is a two-dimensional treadmill that allows a walker to walk forward, backward, left, An X-axis driving part 200 for circulating the tread part 100 in the X-axis direction, and a Y-axis driving part 300 for circulating the tread part 100 in the Y-axis direction.

As shown in FIGS. 1 and 2, the tread part 100 is moved in the X-axis direction and the Y-axis direction so that the pedestrian can move in all directions in two dimensions, have.

In this case, it is needless to say that the pedestrian described above can be applied to various fields such as a robot having a human joint, a transportation apparatus, and the like.

The tread part 100 includes a unit body 110. The unit body 110 is formed so that both ends of the unit body 110 are parallel to each other in the X-axis direction and is rotatable in the X-axis direction.

In this case, the tread portion 100 includes a tread 120 formed to surround the unit body 110 in the Y-axis direction and configured to be circulatable in the Y-axis direction.

That is, the tread portion 100 can be moved in the Y-axis direction by forming the tread 120 so as to be circulatable in the Y-axis direction on the unit body 110, and the unit body 110 By being formed so as to be rotatable in the X-axis direction, movement in the X-axis direction can be realized.

In this case, the body connecting part 312 includes a rotating roller 312-1 formed at both ends of the body connecting part 312 so as to be rotatable in a horizontal direction with respect to the plane of the ball body 311.

That is, the omni-ball 310 is fixed so that the body connecting portion 312 is rotatable in the horizontal direction of the plane of the ball body 311, and is fixed to the ball body 311 in a direction perpendicular to the plane of the ball body 311 .

The Y-axis soccer portion 300 including the omni-ball 310 described above is formed such that the omni-ball 310 is at least one or more than one face-to-face contact with the outer surface of the tread 120 in the horizontal direction of the ball body 311 .

The oval ball 310 is connected to the body connecting portion 312 between the flat surfaces of the ball body 311 to fix the oval ball 310 in contact with the tread 120. The oval ball 310 is rotated in the Y- And a power rotating part 320 for supplying a rotating force as much as possible.

That is, the omni-ball 310 is rotated in the direction perpendicular to the plane of the ball body 311, that is, the Y-axis direction, by receiving the rotational force from the power rotation unit 320, and the ball body 311, The tread 120 can be circulated in the Y-axis direction.

The omni-ball 310 is rotatable in the horizontal direction of the ball body 311 by the rotation roller 312-1 so that the omni-ball 310 can be rotated in the horizontal direction of the ball body 311, And a free-rotation motion is possible in the direction.

In other words, the omni-ball 310 of the Y-axis driving part 300 is formed by being in contact with the outer side surface of the tread 120 so as to be in contact with the point, The tread 120 can be circulated in the Y axis direction and the omni ball 310 can freely rotate in the X axis direction so that the unit body 110 can move without interference even when moving in the X-axis direction.

It is recommended that the omni-ball 310 of the Y-axis drive unit 300 be provided with a plurality of omni-balls 310 for improving frictional force. However, it is preferable to control the number of omni-balls 310 provided according to a simulation situation to be reproduced can do.

The power rotating part 320 serves to fix the omni-ball 310 in contact with the outer surface of the tread 120 and to prevent the ball body 311 of the omni-ball 310 from rotating in the Y- And serves to supply a rotational force to assist.

It is needless to say that the shape of the power rotation part 320 is not limited and that various forms and positions of the power rotation part 320 are possible as long as the omni ball 310 can be freely rotated in the X axis direction and the Y axis direction.

It is recommended that the Y-axis driving section 300 be formed at both ends of the tread section 100 in the Y-axis direction for precise speed control of the tread 120 which is moved in the Y-axis direction and is circulated. However, It is needless to say that various positions and numbers can be provided.
