BICYCLE OR MOTORCYCLE FRAME

Abstract: Steel or light alloy frame for bicycles or motorcycles. It has: forward inclination of the front forks of an angle (3), variable diameter of the front wheel, distribution of weight according to angles (5, 6, 7), a new way of considering the hubs (1, 2), as application points of the dynamic moments obtained by the weight force for the distances (8, 9 and 10). Variability of the measures and angles which make up the frame. Higher speed, lower costs, healthier work, less polluting discarded material.

Description: Title: BICYCLE OR MOTORCYCLE FRAME DESCRIPTION OF INVENTION Technical field The invention consists of a new frame for bicycles or motorcycles. It is made of steel or light alloy. The new frame is different as far as shape, design, measures, structure and the concept related to it are concerned. The weight force is exploited in the best way and the dynamic moments can be applied. The invention can find suitable application in either the mechanical industry producing steel frames or in industries specialized in light alloy frames. Background art The invention is the result of the study of physics, of statics and dynamics in particular. The new bicycle frame exploits the second principle of dynamics by which a force applied to a body which is free to move will produce an acceleration of the body itself. A prototype I have made supports my thesis. Disclosure of invention The hubs, indicated by (1) and (2) in the drawing, are not obligatory points for the passage of weight force and motive power. In the new frame they become application points for the dynamic moments. The front fork is bent forward of an angle (3) as well as the upper rear fork, while, according to the previous concept of frame, the front fork was bent backwards, as indσated by (W) , of an angle (4). More advantages can be obtained by changing also the front wheel diameter. Changing only one angle of one of the parts which compose the frame, the other angles of the structure change too. If wheels of the same or different diameter are used, the position and shape of the saddle and the handle-bar can change even though the wheel base remains the same. As a rule, the other parts of the frame remain as they traditionally are. Description of the drawing The new frame changes for the angularity of the various parts: the top tube, the steering column, the upper rear fork, the lower rear fork and the front forks; for the forward inclination of the front fork of an angle (3) compared to the angularity (A) of the traditional frame indicated by (W) . The angles (3) and (4) refer to the perpendicular to the base line passing through the front hub. It changes for the different angulation of the parts of the frame, (6), (7), (8), compared to the parallel lines to the base line; for the different way of conceiving the distribution of weight force, for the distances (8), (9), (10), and for the calculation of the dynamic moments. Best mode for carrying out the invention The more the weight power increases, the more the distances from the application points and, in turn, the forward pushing moments increase. For this reason locomotion machines can be produced according to one's needs or interests. People will choose the new bicycle because it is faster on flat land, slopes and could be the ideal bicycle for races. The best results and the highest speed can only be obtained by riding bicycles or motor-cycles which are suitable for the rider. Industrial applicability The new bicycle with a steel frame is faster than one produced with a light alloy frame and in accordance to the traditional concept indicated by (W) . Higher speed at low costs is granted maintaining the same motive power. Speed can increase from five to ten per cent by using steel frames of standard measures. The price could be lower and the product could be bought by everybody. Steel working is healthier for the workers and the discarded material is less polluting compared to the light alloys which are used nowadays to increase speed.

Claims: CLAIMS 1_ The new frame, made of steel or light alloy for bicycles or motor-bicycles is characterized by the forward inclination of the front forks of an angle (3), compared to the backward inclination of an angle (4) of the forks in the traditional frame indicated by (W) . 2_ The pushing forward rotatory movements provoked by the weight force can be applied to the hubs for the distances (8), (9) and (10). 3_ The weight force can be discharged on the wheels (1), (2) in a better way. _ The heavier the frame, the more the rider increases the forward push according to the angles (5), (6), (7) and the faster the bicycle or motorcycle runs. Nobody has applied for a patent or officially produced a machine with these characteristics. 5 ^ The new frame grants higher speed, lower costs, healthier work, less polluting discarded material.
