STATIONARY ARTICULATED BICYCLE 0007 Later Lim, 2001, patent U.S. Pat. No. 6,322,480, says a bike in an enclosed space became one of the most TECHNICAL AREA popular tools to exercise without spending much time, these bikes include a base in which the chassis is mounted, and this 0001. The present invention relates to a stationary rotu base is fixed to the chassis so that it can not move or rock lated bicycle for physical exercise, especially for interiors during the action of pedaling. So when a person is prepared to (indoor). Such as sports centers and fitness centers, this equip go on a bike like that, he can not feel the activities covered by ment is covered with very unique and peculiar technical fea oscillating outdoor , getting easily tired of this type of tures, when being compared with the principles of Solution bike in an enclosed space. Thus the author describes the presented by the relevant devices in the state of the art in this improvement of a bicycle in enclosed space, which has report. unsteadiness, providing activities like the bike to Swing open, 0002. In essence, it is seek with the invention, the charac the benefit is that you do not feel pain in the muscles. terization of a new design of stationary bike which has a 0008 Later Ziad, 2005, underpublication in PCT No. WO rotula, located between two elements of a structure, to allow 2005/046806, presents a new design for indoor exercise their relative angular displacement, which is intended to pro bicycles, which are unstable, having a system to control the vide a combination of balance and freedom offering excellent instability, simulating a feeling of being pedaling on a mobile comfortable to absorb all the impact on the physical set of the bicycle. USC. 0009 Recently Peterson, 2008, patent U.S. Pat. No. 7,326, 151, says that most of the training devices presented in the STATE OF THE ART market, to be mounted on conventional bicycles, only pro 0003 Currently, there are many bicycles being used for vides movement of pedals and crank. This is a problem physical exercises in internal environment. The modality for because the training can not simulate a hill climb, allowing which the object of the invention is directed is popularly the side balance that moves the bike as in real conditions of known as “spinning”, “indoor cycle.” “RPM’, etc., And that outdoor use. He said that, then it was produced a device to be for this type of exercise bicycles have a special form with a attached to a bicycle that simulates real conditions of use. wheel of inertia called steering wheel, that lets you adjust the load of pedaling according to the appropriate level of training, Problems in the State of the Art depending on the creativity of the user. The practitioner looks 0010 Considering the state of the technique previously for this modality to achieve increased calorie burning, and prolated, in the use of the inventions listed, it can be attributed thus a quicker and more efficient result to obtain its physical some drawbacks. Chang, 2000, patent U.S. Pat. No. 6,126, fitness. 577, describes the use of hydraulic cylinders to generate 0004. According to Augspurger, 1991, patent U.S. Pat. angular movement causes the exercise bike can not move No. 5,050,865, the bicycle is one of the most beneficial forms quickly back to its vertical position and it is unstable in use, of , conditioning the individual to Sustain an thus making it unfit for practical use (column 1, lines 29 to increase in heart rate without the impact of the physical set 32). Thus, U.S. Pat. No. 5,050,865 and U.S. Pat. No. 5,035, which is proportionate to other forms of exercise Such as 418 are inadequate for the application, since they assume running. for exercise is popular as it is an activity that Solution using this type of mechanism. Therefore, Chang can be performed by people of all ages. However, there are himself says he has solved the instability problem adding limitations as to time, or other weather conditions that do not springs in the system, same principle later used by Peterson. allow the cyclist riding a bicycle outside of indoor environ The fact is, both authors, do not remove the hydraulic cylin ments, on a road or street. In this situation, the author presents ders, they just add springs, with the intention to stabilize the in his invention a stationary device adapted to Support a system and they make it insensitive, not favoring the comfort conventional bicycle and the combination may be operated as of the user. a stationary exercise machine. 0011 Ziad probably took into consideration the question 0005. According to Harabayashi, 1991, patent U.S. Pat. “instability”, for he presented an assisted control for this No. 5,035,418, the conventional athletic facilities are con through a pump or an electric motor, predicting the possibility structed to form strength in the user's legs in a stationary of the cylinders being on gas. Together with the lateral system position but not for both sides during pedaling. However, of articulation, he also arranged the simulation of curves via cycling real, there is not just a straight track, but also upward a movable handlebar. In critical analysis to the mentioned and downward path. Thus, the author displays in the object of invention (WO 2005/046806), it is unwise to say the system his invention, a type of athletic equipment that can tilt the seat does not work, but an expert in the technical issue may agree of the user to any angle in any direction during pedaling, the invention presents complexity in its operation, making it reinforcing the strength of the legs. difficult to adjust properly the system in general. Another 0006. According to Chang, 2000, patent U.S. Pat. No. concern is the issue of positioning the axis of rotation, which 6,126,577, there are a number of physical devices for allow allows angular movement that is set above the ideal point for ing people to exercise in indoor environments. For example, obtaining the proper functioning which would simulate a the stationary bike, as one of the best machines to a program street bicycle. of cardiovacular conditioning. However, the conventional models are rigidly mounted in a fixed position, making it SUMMARY OF INVENTION unable to simulate angular movements, causing a nuisance to the user in a short period of time. Based on these consider 0012 For that reason, it is the intention of this invention to ations, the author explains that the main objective of his characterize a stationary rotula bike that will solve all issues invention is to provide an improved exercise of Stationary presented, guaranteeing a product with excellent functional bicycle which can be balanced from side to side. outcome, suitable for the practice of the exercise said previ US 2011/O 105282 A1 May 5, 2011

ously. The focus of the invention is in the lattice degrees of 0023. With the functioning of the system the bases are freedom, allowing angular movement Supported by a torsion likely to move up with the intention of jumping off the table bar, while offering a combination of balance and freedom, (2) so the bearing bushing (9) was fixed to the square frame sensitive to forces applied to remove all and any impact that work (2) through the screw (5). occurs in bone and nerve structure of the human body, pro 0024. The operation of the stationary rotula bike is very viding comfort to the practitioner. simple and can be described as follows: the front (3) and rear bases (4), supported on the floor, let the bike (1) develop DESCRIPTION OF PICTURES angular movements through the bush of bearing (9). These movements are limited by the torsion bar (8), providing a 0013. In order to illustrate and clarify the invention, it is balance point to the bike (1). made reference to the illustrative attached drawings that con 0025 By pedaling the bicycle, the user exerts forces, once stitute and Support the present descriptive report, and where in each foot in turn. This force makes the bike turn on the you see: 0014. In picture 1, a view in perspective of dimeter of the bearings, and is absorbed by the torsion bar.
