Description
IMPROVED BICYCLE STRUCTURE
The present invention relates to an improved bicycle structure.
In particular, the subject invention finds advantageous use in competitions on road, dirt road or track, to which the following description will make explicit reference without thereby losing generality.
The purpose of the present invention is to provide an improved bicycle structure provided with at least a component to which an instrument is applied, to allow the measurement of some parameters useful for the assessment of the performance of the cyclist and/or of the bicycle itself during its use.
The structural and functional characteristics of the present invention and its advantages over the known art will be clearer and more evident from the claims below, and in particular from an examination of the following description, referring to the attached drawings, which show some preferred but not limiting embodiments of an improved bicycle structure, in which:
Figure 1 is a schematic front view of a preferred embodiment of a first component of a bicycle structure;
- Figure 2 is a schematic side view of the component of Figure 1 ;
Figures 3 and 4 are perspective views from above and below of the component of Figure 1 , respectively;
Figure 5 is a schematic front view of an alternative embodiment of the component in question;
- Figure 6 is a schematic side view of the variant of the component of Figure 5;
Figure 7 is a bottom perspective view of the component of the variant of Figure 5;
Figure 8 is a further variant of the component shown in Figure 6;
Figures 9, 10, 1 1 and 12 are respective side, front, top plan and perspective views of a part of the component of Figures 1 to 8;
Figures 13 and 14 are respective front and side views of an embodiment of a second component of the present bicycle structure; and
Figures 15,16 and 17 are respective side, front and perspective views of an embodiment of a third component of the present bicycle structure.
With reference to the attached Figures 1 to 12, M refers to a first component, namely in this case a handlebar M integrally formed with a bicycle structure K, able to allow the control of the direction of the vehicle-bicycle by means of the user's- cyclist's hands, comprising a main cylindrical tubular element 1 , provided with ends 2' and 2", which are opposite to each other and suitable to be grasped by the bicycle user, and substantially arranged transversely to the frame and to the rear wheel of the bicycle itself (known and not illustrated), the element 1 being connected to the frame T of the bicycle via a coupling or stem 3 formed by the element 1 (as in the attached Figures 1 to 8), and oriented horizontally and perpendicularly to the element 1 in a middle part 4 of the element 1 itself. In particular, the stem 3 is provided with a suitable hole 5 to be inserted on a tube (not shown) of the bicycle frame.
According to Figures 9 to 12, the stem 3 forms a separate element that is connected to the element 1 and to the bicycle frame by means of known connection means. In known manner, and not illustrated here, the ends 2' and 2" are generally provided with levers of known braking means of the bicycle.
According to the embodiment illustrated in Figures 1 to 4, the handlebar component M is preferably suitable to be used on road racing bicycles during time trials or on track bicycles, and the element 1 is substantially U-shaped with the grasping ends 2' and 2" facing forwards (in the direction of advance of the bicycle). According to a variant known and not shown, the element 1 can also be provided with special extensions known per se and parallel to the ends 2' and 2" on which the cyclist is able to support the forearms to obtain an improved aerodynamic penetration.
According to the variant shown in Figures 5 to 8, the handlebar component M is preferably suitable to be used on road racing bicycles, and the element 1 has a known conformation, called "bull horns" or "ram horns", which allows a low grip for a greater control and an optimal aerodynamic penetration, with the ends 2' and 2" facing backwards (in the direction of advance of the bicycle along the road).
As illustrated in Figures 1 to 12, the unique innovative feature of the handlebar component M is to support, being either directly integrated or anyway formed integrally with the stem 3 transverse to the element 1 , a hollow through cylindrical tube 6 (Pitot's tube), inside of which a proximity sensor S (fig. 7) (of type known per se) can be placed, for the detection of various useful parameters, including, for example, the air pressure for the altitude calculation (altimeter), the position and/or the speed of the bicycle, or other similar useful parameters.
The sensor S is connected to a computerized device (known per se and not shown), attached to a plate P also provided integrated in the structure of the stem 3 or the element 1 , and adapted to detect and control numerous and various additional parameters, including, in addition to the altitude and/or speed of the bicycle, the geo-localized/GPS position, the user's-cyclist's heart rate by means of a heart rate monitor, an odometer, a chronometer etc.
According to the variant shown in Figure 8, the handlebar component M is not provided with the integrated plate P, and a computerized device is attached to the handlebar M itself by screw fixing means or similar means.
According to the embodiment illustrated in Figures 13 and 14, the bicycle structure K, preferably for a road racing bicycle during time trials or for a track bicycle, includes a front fork component F adapted to support a wheel (not shown) in a known manner.
Such fork F is advantageously adapted to support a directly integrated, hollow through cylindrical tube, equal to that described above with the reference number 6 for the handlebar component M, in which, within said tube 6, the above proximity sensor S can be positioned.
According to the embodiment illustrated in Figures 15 to 17, the bicycle structure K, preferably for a road bicycle during time trials or for a track bicycle, includes a portion Z of the frame T of the structure Z itself.
The portion Z if the frame T is advantageously adapted to support a directly integrated, hollow through cylindrical tube, equal to that described above with the reference number 6 for the handlebar component M, in which, within said tube 6, the above proximity sensor S can be positioned.
