Description

AERODYNAMIC SUIT FOR BICYCLE AND MOTORCYCLE DRIVERS
TECHNICAL FIELD This innovation relates to the modification of the suit form for bicycle and motorcycle drivers. This form allows considerable reduction of aerodynamic shape resistance.
BACKGROUND ART It is known that the object which has the shape of the rain drop has an optimal form regarding aerodynamic resistance, i.e. it creates the lowest turbulent wake in air stream. As the form of the drivers body considerably differs from the shape of the rain drop it is clear, that the aerodynamic resistance of the driver's body, due to the creation of strong turbulent wake behind the driver is considerably larger than minimum obtainable. It follows that aerodynamic resistance during bicycle; motorcycle ride is mainly determined by the resistance of the driver's body. Body motion through the air is opposed by the aerodynamic resistance. Aerodynamic resistance is formed by two components: friction drag and shape drag. Friction drag is determined by the surface roughness of liie body in the streamline, and shape drag is related to the form of the body. There are different solutions for the improvement of the outer form of the helmets and the bicycles/motorcycles. All these solutions tend to modify outer form of the object into (close to) the form of the rain drop. Up to now there is no such solution for the driver's suit. Thanks to the choice of the adequate materials for the driver's suit with the smooth outer surface the friction resistance is reduced to some extent, but as the driver's suit completely follows form of the driver's body shape drag is practically equal for the driver with and without the suit.
DETAILED DESCRIPTION OF THE INVENTION Primary purpose of this invention is to reduce aerodynamic resistance of the driver's body (bicycle / motorcycle) by the appropriate form of the driver's suit. In this way, energy consumption per mile will be reduced; physical energy in case of the bicycle driver or chemical energy in case of motorcycle driver. Further, described invention will reduce turbulent wake around the driver's body. This is especially important for the bicycle driver because standard suits are not sufficiently thick to stop cooling of the sweated, back side of the driver's body by the turbulences. As this cooling, in long time period, can cause chronic injures this invention will bring improvements for the driver's health. The aerodynamic suit for the bicycle (motorcycle) driver is composed of basic part that provides all functions of the suits already presented on the market and additional part which is dedicated to reduce aerodynamic drag by reducing turbulent wake. This additional part has conical form that extends from the basic part. By this, shape of the driver's body is brought closer to the shape of the rain drop. As the rain drop shape has minimal aerodynamic drag it is obvious that turbulent wake and aerodynamic resistance of the driver's body will be reduced. This, additional part represents the aerodynamic extension that helps to reduce the aerodynamic drag by the reduction of the turbulent wake. In addition, on the front part of the suit some rounded implants can be putted and added to bring outer form close as much as possible to the form of the rain drop, and by this further reduce aerodynamic drag. Further, space inside of the aerodynamic extension can be used as the pocket(s) for the food, beverage and other useful things during the race or tourist ride without increasing aerodynamic resistance. By the reinforcement of the aerodynamic extension coat made of thermal isolation material, contains inside of the aerodynamic extension will be protected against the heat transferred with environment. This will preserve quality of the food and beverage placed inside of the aerodynamic extension. Beside reinforcement of the aerodynamic extension coat will reduce vibrations of the coat itself which will additionally improve aerodynamic properties of the mentioned aerodynamic extension. Empty space inside the aerodynamic extension can be used for implementation of the additional protective implants which will protect the driver against serious injuries (i.e. vertebral column) in the case of an accident. This is especially important with motorcycles where due to higher speed risk of serious injuries is greater. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION This invention relates to the improvement of the aerodynamics of the driver's suit. Since it is concerned about the subject that impose additional weight to the drivers body it is logical request to reduce the increasement of the load introduced by the aerodynamic extensions. Therefore, it is natural to use technologies that can be found in aircraft constructions which are of the aerodynamic form and of minimal weight. Driver's suit can be considered as aerodynamic core, whose form is determined by the driver's body and by the corresponding support elements either on driver's body, bicycle construction or onto the drivers body and onto the bicycle construction. Support elements have double roles. First, and the basic one role, as it has been already said, is to produce needed aerodynamic form of the aerodynamic suit. Second one, not less important one is to secure right position of the aerodynamic extension/extensions in the air stream independently of the driver's position keeping the resistance on the lowest level. It follows that the main point of this invention is new aerodynamic form of the suit made by some known technique of the suit production, as well as to the corresponding form of support construction made by some technologies (i.e. composite materials) known in light weight constructions (i.e. aircrafts) so there is no need for detail description of the technologies. What is original in this invention is the form of the driver's suit and supporting elements which will be shown by the following figures. FIG. 1 shows the silhouette of the bicycle driver wearing aerodynamic suit 1 which reduces turbulent wake in the air stream around driver's body. This suit can be made as one or composition of several parts. The aerodynamic extension 2 is connected to the basic part by the disconnectable connection 3. By the addition of the opening 5 one can put and take out objects, aerodynamic extension can be used as the storage place for food, beverage and other usable things. If the aerodynamic extension is used as the storage place then conical ending can be performed with the bottom and with appropriate strap(s) it, aerodynamic extension, will be transformed into the rucksack. On the ending of the aerodynamic extension one can see possible shape of the stabilizing surfaces 6 presented by the dotted line. By addition of these surfaces (one or more) aerodynamic extension will be stabilized regarding perpendicular direction. FIG. 2 shows the aerodynamic suit in the side partially sectional view with supporting structure made in technology of self-supporting core 7. Possible rounded shape 8 is aimed to reduce the risk of the injuries in case of the accident which is shown by dotted line. FIG. 3 shows aerodynamic suit where required form of the aerodynamic ending is obtained by the tensioning forces in the skin of the aerodynamic extension caused by the deformation of the flexible support element 9 fixed to the bicycle frame 10. Mentioned, flexible support element is made out of the spring-steal or composite material which allows higher flexibility. With the appropriate cross-section of the flexible support element different rigidity in different directions (i.e. reduced rigidity in vertical direction) can be obtained. By this, driver can easily move along the driving path and at the same time sideway bending of the flexible support element is reduced. Sideway bending of the aerodynamic extension can reduce driving stability and increase aerodynamic resistance therefore, it has to be reduced. With the additional flexion limiter 11 placed by the side of elastic support element (as on the drawing) or on the upper side or both sides, oscillating bending of support element i.e. the aerodynamic extension can be reduced. Namely this limiter of flexion is considerably of higher rigidity than elastic support element. During the bending of the elastic support element its natural frequency will be affected by the contact with limiter of flexion which will reduce amplitude of oscillations. Both, elastic support element and flexion limiter can be fixed on their carrier through the rotational connection 12, 13. This rotational link serves for adjustment of the angle between elastic supports elements, flexion limiter and their support on the bicycle frame. By the means of friction and/or screw connection it is possible to secure the required position. FIG. 4 shows performance of the aerodynamic suit where the required form of the aerodynamic ending is secured by tensional forces in elastic supporting element 14 inserted between support elements 15 fixed on the bicycle frame 16 and the ending of the aerodynamic extension. In order to additionally reduce the influence of the possible oscillating bending of the aerodynamic extension to the quality of the driving, one can add passive or active vibration damper onto the aerodynamic suit. The passive vibration damper basically consists of three main elements i. e. mass, spring and damper. Adding some small movable weight 17 onto the aerodynamic extension or flexible support element at the part with appropriate section the natural frequency of the passive absorber can be adjusted. Textile of the suit is used as the damper. Active vibration absorber can be realized by piezo actuators and controlling unit added onto the elastic support element 15 as it is known in production of the 'intelligent sides'. FIG. 5 shows aerodynamic suit where the required suitable form of the aerodynamic extension, which is similar to the previous solution, assured by tensioning forces in the elastic element 18. But, with this solution force produced by spreading of the elastic element 18 is transferred by the rigid support 19 onto the ending of aerodynamic extension 20. By this solution the elastic element is completely incorporated into the aerodynamic extension and by which the length of the support element fixed onto the bicycle frame can be reduced. Reducing the length of the support element its weight is also reduced, and stiffness is increased what is desirable in the view of reducing risk of undesirable bending oscillation of the aerodynamic extension. FIG. 6 shows the performance of the aerodynamic suit where supporting construction is formed as the unique support 21 which by one end is pressed against the driver's body while with the other end pushes the end of the aerodynamic extension. FIG. 7 shows the performance of the aerodynamic suit where supporting construction is made as the unique support-spar. This solution is similar to the solution described by FIG. 6 but with the difference that support element-spar 22 is incorporated into the skin of the aerodynamic suit itself. Support element-spar is made as the stick whose cross-section can be of variable form in order to be better adjusted to the driver's body. The mentioned spar is situated in the pocket 23 as it is known from the building of sport flying kites and sales for sailing boats. The length of the spar is a bit longer than the length of the pocket in which it is situated. Insertion of the spar into the pocket and by placing the tensioner 24 over the end of the spar the tensional forces will be created and form of the aerodynamic extension will be obtained. The pocket and the spar in it are located along the driver's back; by which the optimal position of the aerodynamic extension according to the driver's body and air stream around the body itself is secured. In addition, by the appropriate form of the spar it can be obtained the additional protection of vertebral column from the eventual accidents. FIG. 8 shows the performance of the aerodynamic suit where the supporting construction is made as the range of the spars 25 which are incorporated in the skin by means of the range of the pockets 26. This solution reminds on the previously described one with the difference that in this case the range of small spars is used instead of one single. By the appropriate form of the spars one can obtain higher liberty of the form of the aerodynamic extension respectively the skin which is more stable regarding to the vibrations provoked by turbulent wake around the aerodynamic extension. FIG. 9 shows the performance of the aerodynamic suit where the form of the aerodynamic extension is provided either with one pocket as shown on FIG. 7 or by more pockets as shown on FIG. 8 with the difference that pockets 27 are sealed and form is obtained by the pressure of the air or some other gas instead by the spars. Required pressure can be secured either by dynamical pressure created by the movement of the bicycle / motorcycle or by some other source of the pressure (drivers mouth, compressor) introduced by the corresponding valve 28. FIG. 10 shows the performance of the aerodynamic suit where the form of the aerodynamic extension is provided by the inserted inflatable implant of the required form 29. FIG. 11 shows the performance of the aerodynamic suit where the form of the aerodynamic extension is supported by the driver's body as it is shown on the FIG. 2, 6, 7, 8 with the addition of the slider guider of the aerodynamic extension end 30. Slider guider is performed as the opening at the end of the aerodynamic extension. It is fixed to the bicycle by the means of the support element 31. Such mechanism enables to the driver freely moving forward-backward and at the same time it prevents undesirable oscillatory bending of the aerodynamic extension that can reduce driving stability and increase aerodynamic resistance. FIG. 12 shows two of the possible ways of performing primary connection i.e. the connection of the end of the aerodynamic extension and support construction fixed to some part of the bicycle. Both cases are examples of disconectable connection where the joint is obtained by the appropriate form of the parts in connection. In the first case the connection is realized through pin 32 fixed to the end of the aerodynamic extension and inserted into the foreseen cavity 33 on the support construction. By simple taking the pin out, the connection will be interrupted. In the other case the connection is realized through the pocketlet 34 at the end of the aerodynamic extension. This pocklet is put onto the spherical ending 35 of the support construction in order to create connection. Connection can be interrupted by putting off the pocket. When the aerodynamic suit is not in function freely end of the aerodynamic extension represents an obstacle to the comfort driver's walking. In order to prevent it, free end of the aerodynamic extension can be attached to some other part of the suit. This can be performed either by the elements of the primary connection or by the additional elements. One possible solution is to use slot 36 for the insertion of the pin when the aerodynamic suit isn't in function. It is obvious that there is a range of disconnectable connections that can be used.
THE WAY OF USING INVENTION By using the mentioned suit one can reduce aerodynamic drag of the either bicycle or motorcycle driver, therefore to improve sport results or reduce fuel consumption. At the same time this suit enables more comfortable drive due to the reduced turbulent wake around driver's body.

Therefore, it is intended that the invention not be limited to the disclosed embodiments, but that it have the full scope permitted by the following claims.
