Apparatus for three-dimensional anaerobic exercise

Abstract

Disclosed is an apparatus for three-dimensional anaerobic exercise including: A seat mounted on the base frame; handle linkages each inclinedly mounted at right and left sides of the base frame to form an angle ¥á in front of the seat; a bearing box mounted on the front end of the handle linkage; first and second handle frames rotatably mounted on a handle shaft; a handle side lever fixed between the first handle frame and the bearing box in such a manner as to form a predetermined angle with respect to the first handle frame; and an auxiliary linkage connected at an upper end to the handle side lever via a ball joint and mounted at lower end on a fixed lever fixed to the lower end of the front side of the base frame via a ball joint to form a distance (d).

Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus for three-dimensional anaerobic exercise capable of attaining stability in three-dimensional motion trajectories necessary for the human body, and more particularly, to an apparatus for three-dimensional anaerobic exercise, which applies a reduction linkage concept, but not a four-rod linkage concept disclosed in Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712, previously filed by the inventor of the present invention, for safe three-dimensional motion trajectories in approach to each of various regions of the human body, thereby increasing durability, reducing manufacturing costs, and realizing motion trajectories of various kinds, which are merits of the three-dimensional exercise. [0002] In addition, the present invention relates to an apparatus for three-dimensional anaerobic exercise, which can provide a new approaching method for overcoming lots of limitations of Korean Patent Applications,...

AI Technical Summary

Benefits of technology

[0038] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus for three-dimensional anaerobic exercise, which is another approach of apparatuses for three-dimensional exercise using four-rod linkage (Korean Patent Application Nos. 10-2001-0059174 and 10-2001-0078712 previously filed by the inventor of the present invention), and which can apply safe and efficient motion trajectories realized by the four-rod linkage to a reduction linkage concept.

[0039] The four-rod linkage for realizing the three-dimensional motion trajectories has an advantage in that an angle of a handle can be maintained uniformly in a movement direction of the human body as an angular motion of the four-rod linkage is not influenced by rotation of the handle. However, the four-rod linkage is not good as having complicated structure and form, a heavy volume, and expensive manufacturing costs.

[0048] In the above structure, gearing means and a damper in stead of an auxiliary linkage can be utilized to enlarge the angular motion range of the handle. Furthermore, a cross joint mounted on the lower shaft can realize wide three-dimensional motion trajectories, and has a guide linkage for freedom and specified twist structure. The combination between the cross joint and the guide linkage can realize motion trajectories, which were not realized by the conventional reduction trajectories.

[0050] As described above, the apparatus for three-dimensional anaerobic exercise according to the present invention can provide three-dimensional motion trajectories suitable for the human body and allow the human body to do more improved exercise.

Problems solved by technology

However, the four-rod linkage is not good as having complicated structure and form, a heavy volume, and expensive manufacturing costs.

The reduction linkage concept proposed as an alternative measure of the four-rod linkage may impose a heavy burden on an exerciser's wrists and forearms as the angular motion of the handle linkage has an influence on the angle of the handle.
