The present invention relates to a bicycle exercise apparatus, and more particularly to a multiply convertible bicycle exercise apparatus in which various types of exercise can be enjoyed because the form of the bicycle exercise apparatus can be changed into various forms, the shape and size of the bicycle exercise apparatus can be adjusted to fit a user's physical size even in a converted state, the bicycle exercise apparatus is stable in connection with the center of gravity thereof by changing the center of gravity of the bicycle exercise apparatus from a lower end to an upper end, the bicycle exercise apparatus is free to tilt and move in all directions, and the cycling effect of pedaling while sitting on a chair and a riding exercise effect and a buff bike exercise effect attributable to the elastic force of springs can be obtained together.
In general, cycling is the most economical and effective exercise method capable of maintaining and improving health and physical strength.
Cycling is an aerobic exercise that mainly uses large muscles of the lower body, and is an exercise that can develop a cardiorespiratory function and the muscle strength of the lower body, can improve a circulatory system function and muscular endurance, and is effective for people with weak lower body muscle strength, people with weak joints, people with osteoporosis, and people with obesity because it does not put strains on the joints.
In addition, cycling has the advantage of being able to do exercise without boredom because it runs a relatively long distance on various courses and terrains.
Recently, many bicycle exercise apparatuses that enable exercises to be done indoors by using bicycles are widely popularized. A general bicycle exercise apparatus gives an exercise effect to the thighs and the calves as a user steps on pedals, and allows the buttocks and the waist to shake from side to side as a user alternately steps on both pedals, so that a corresponding exercise effect and a weight reduction effect occur.
Such a bicycle exercise apparatus commonly includes a saddle configured such that a user can usually sit and exercise thereon, a bicycle body connected to the bottom of the saddle by saddle pipes, a base frame fixed to the lower side of the bicycle body and configured to support the bicycle body, a handle pipe attached to the upper portion of one side of the bicycle body at a predetermined angle and a handle fixed to the upper side of the handle pipe, and a pair of pedals installed on both sides of the center of the bicycle body.
The above-described bicycle exercise apparatus allows a user to do exercise in such a manner that the user sits on the saddle, grips the handle, puts his or her feet on the pedals, and then rotates the pedals by stepping on the pedals.
In this case, the bicycle exercise apparatus installed indoors has advantages in that a user can set the intensity of exercise by adjusting speed and resistance at the desired time regardless of the season and weather, so that a more accurate amount of exercise can be done than in the case of outdoor exercise. However, the bicycle exercise apparatus has disadvantages in that an exercise process is tedious because the bicycle exercise apparatus is configured to allow a user to do exercise by simply stepping on the pedals indoors and also in that dust is generated indoors during exercise and, at the same time, powder from the friction surfaces of bicycle wheels can have a bad effect on the respiratory system of the human body.
In addition, since the bicycle exercise apparatus is configured to allow a user to do cycling exercise by stepping on the pedals in a sitting state, partial exercise centered on the lower body is possible, but there is a problem in that there is a limitation in obtaining the effect of full-body exercise.
Furthermore, since the bicycle exercise apparatus is configured to be suitable for adults, there is a problem in that it is difficult for all family members including men and women of all ages to use it.
In addition, although the bicycle exercise apparatus has a considerable size and occupies a predetermined space indoors, it has no separate function other than a cycling exercise function, so that there is a problem in that the efficiency of the bicycle exercise apparatus is lower compared to the installation site thereof.
In order to solve the above-described problems, there was proposed a dancing- and riding-type bicycle exercise apparatus configured such that individual sides of the conventional bicycle exercise apparatus 10 were connected by spring members 11 and were tilted forward, backward, left and right within a predetermined range by the elastic force of the spring members.
However, in the case of the bicycle exercise apparatus, the center of gravity thereof is formed at the lower end of the bicycle exercise apparatus during exercise, and thus the weight is concentrated to the lower end during dancing-type exercise using the bicycle exercise apparatus 10. When the bicycle exercise apparatus 10 is inclined to one side due to the weight of the user, there is a safety-related problem such as the falling of the user
Therefore, there is a demand for a bicycle exercise apparatus that has various exercise functions as well as a simple bicycle riding exercise function and can be safely used by a user.
