Union Cycliste Internationale (UCI)—a.k.a. in English as the International Cycling Union—is the world governing body for sports cycling and oversees international competitive cycling events. Among its various duties, the UCI manages the classification of races and the points ranking system in various cycling disciplines including mountain biking, road and track cycling, for both men and women, amateur and professional. It also oversees the World Championships.
One of the more controversial roles of the UCI resides in the technical regulations it establishes and enforces with regard to the eligibility of bicycles used in the varying types of racing discipline. Although many feel that the rules arbitrarily restrict riders from achieving faster times, the UCI counters that strict adherence to these rules “guarantees sporting fairness and safety during competition.” As such, racers' bikes must conform to the standards set when wishing to compete in most any UCI sponsored event; and especially those in the three disciplines of: road events, track events and cyclo-cross. Each discipline has its own technical characteristics and each may have variants depending on the type of event.
For example, in massed-start road races and cyclo-cross, Article 1.3.020 of the UCI technical regulations states that the frame elements shall be tubular without excessive curvature (a straight line along the element's longitudinal axis must remain inside the element). Further, the regulations state that the elements shall have a maximum transverse dimension of 8 cm and a minimum transverse dimension of 2.5 cm (reduced to 1 cm for the seat stays, chain stays and forks).
The above max/min traverse dimensions are further limited to a “1:3 ratio”, which applies to the shapes of bicycle elements, with the exception of moving parts (wheels and chainsets1) and the saddle. Likewise, Article 1.3.024 establishes that aerodynamic assemblies and protuberances on the head tube are prohibited. More specifically, the Regulations do not allow for protective screens, aerodynamic shapes, fairings or any other device added or forming part of the structure, which is destined or has the effect of reducing wind resistance. Nevertheless, this regulation does not apply to the pedals, front or rear derailleur bodies or wheel brake mechanisms. The regulation does, however, apply to all elements making up the frame architecture as well as frame accessories (stem, handlebars, handlebar extension, seat post).
Notwithstanding any of the above, the subject of the shape of bicycle elements (1:3 ratio) does not exempt manufacturers from complying with the official “racing bicycle” standards when concerning uncovered projections, which, e.g., must be rounded for safety. Further, the 1:3 ratio does not limit other items including: brake levers, gear levers, bottle cages and other items; however, such elements with “knife-edge profile” shapes are not allowed.
To illustrate Regulation 1.3.024 (1:3 ratio), when using the maximum transverse dimension authorized for an element, namely 8 cm, the associated minimum transverse dimension is 8/3=2.66 cm. Likewise, when using the minimum transverse dimension authorized for an element, namely 2.5 cm, the associated maximum transverse dimension is 2.5×3=7.50 cm. For all intermediate options, the maximum to minimum transverse dimension ratio cannot exceed three.
Except for individual and team pursuit (kilometer and 500 time trials), only the traditional type of handlebars are authorized for use in massed-start road races, cyclo-cross and track competitions (under Article 1.3.022). Further, additional handlebar components or extension attachments are prohibited.
In contrast, for time trials on the road and track competitions the elements making up the frame are not restricted provided they fit freely inside a defined template (see regulations) and comply with the 1:3 ratio described above. (See comments on Article 1.3.021 and Article 1.3.020). Further, the bicycles may be fitted with an “additional handlebar” (extension) upon which elbow or forearm rests are authorized without these representing supplementary points of support (in contradiction of Regulation 1.3.008). The extension, as the name indicates, extends the handlebars in the horizontal plane and needs to be fitted with handgrips, which may be located on the handlebar extension horizontally, inclined or vertically. Nevertheless, the profile of the extension must conform to the 1:3 ratio in accordance with Article 1.3.024. Further, the extension must be fixed and not feature a system that would allow a change of length or angle during the race.
Although the use of handlebar extensions puts the rider in a more aerodynamic position for the road and track competitions, such position has unintended consequences. For example, because the rider's arms remain tightly held under the chest of the rider and slightly extended in a somewhat “superman” position, it becomes difficult for the rider to change this position or take her hands off the handle bar section without creating unwanted drag. Accordingly, when the rider needs water or other nutritional fuels during a race, the rider must shift their weight in order to reach for a bottle in a rack typically below their seat. Such shifting and reaching not only adds unwanted drag from the body's position, but may also cause a change in balance on the bike, resulting in stability issues. Further, because one must typically look in the direction of the water bottle to reach for it, the rider's attention is drawn away from the race and obstacles on the course—obviously increasing the risk for a serious accident due to any number of changed circumstances or unexpected events that require the rider's immediate attention. Although the odds of such unforeseen accident are low when a rider tries t reach for such items, even the most skilled rider will (at a minimum) experience a reduction in speed due to: (i) unwanted drag from change in optimal aerodynamic body position or angle; and (ii) decrease in pedaling momentum due to, e.g., lack in focus from sight diversion and/or changed bicycle stability from body movement.
Due to these inherent problems of current bicycle water bottle systems, there remains a need for a hydration and/or nutritional system that allows a rider to easily obtain the needed fuel with minimal movement and distraction. As an added consideration, the system should preferably improve aerodynamic performance; however, if necessary, it can still comply with the 1:3 ratio and other international bicycling regulations as outlined above by the UCI and other similar regulatory agencies.
Example embodiments of the present invention overcome the above-identified deficiencies and drawbacks of current bicycle hydration and nutrition systems. For example, embodiments described herein provide for an integrated hydration and nutrition container with the handlebars of a cycling system (e.g., a bicycle). Such integration allows a rider easy access to the nutritional value necessary for high performance competition with little to no movement required, thereby allowing the rider to maintain focus, balance, speed, aerodynamic efficiency. Further, embodiments provide for an aerodynamic hydration and nutritional center, which although integrated with the handlebars of a bicycle may conform to the international regulatory schemes, but can also be easily removed with, and if, the regulating authority does not allow such systems. Typically, the system is easily removable, if desired; yet holds firmly in place on the desired handlebar positioning during a ride.
Note that this Summary simply introduces a selection of concepts in a simplified form that are further described below in the Detailed Description. Accordingly, this Summary does not necessarily identify key features or essential aspects of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
In order to describe the manner in which the above-recited and other advantageous features of the invention can be obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
In contrast,
The present invention extends to methods, systems, and devices for a removable, yet integrated, storage container for a bicycle handlebar system. The storage container can hold most anything; however, embodiments generally consider its use as a water bottle, feed system, nutritional supplement, or other fuel resource holder. Although the following embodiments generally refer to the storage container as a water bottle or nutritional supplement storage container, any specific use of the contents of the storage container are used herein for illustrative purposes only and are not meant to limit or otherwise narrow the scope of the present invention unless otherwise explicitly claimed.
Turning now to the various Figures, e.g., as shown in
For example, as shown in
Of course, other example embodiments contemplate that the storage container or unit 105 may be accessed through alternative mechanisms. For example, as shown in
Of course, other types of access mechanisms other than caps or straws are also contemplated herein. For instance, the access mechanism may be in the form of a lid for accessing contents of the container 105 other than liquid contents. For example, not shown in the current Figures, example embodiments consider that a lid may be formed in the top of the containers that flip open to allow one to get fuel or food supplements or any other items that one might wish to carry on a ride. In fact, example embodiments further contemplate a combination of access mechanisms. For example, as described in greater detail below, when the storage container resides internally within the handlebars, a combination of lid and suction member may be needed for access. For instance, the lid may allow access to a bladder that holds the contents of the actual container, and the suction device further provides a mechanism for easy extraction while operating the cycling unit. Accordingly, any specific type of lid or access mechanism for extracting the storage container or its contents as described herein is for illustrative purposes only and is not meant to limit or otherwise narrow the scope of the present invention unless otherwise specifically claimed.
For example, the front of the bottle or container may be more rounded, e.g., as shown for example in
As previously noted, regardless of the shape, style, form or number of the storage container 105 units, the container(s) 105 will generally form an integral part of the handlebar 120 system. As such, example embodiments contemplate an aspect ratio (i.e., width to length diameter) of the integrated container 105 and handlebars 120 to range from about 2:1 to 6:1—and preferably about 3:1 or 3 in order to comply with UCI standards. As noted, however, the integrated storage containment 105 and handlebar 120 system may take on other aspect ratios and should not be limited to those noted above unless otherwise specifically claimed.
For example,
In fact, other example embodiments further contemplate other aerodynamic enhancements the overall integrated storage containment and handlebar system described herein. For example, the handlebars 120 may be specifically designed for the storage containment unit 105 and or vise versa. As such, the system will form a tightly integrated feature with optimal aerodynamic properties. Further, this also allows for tighter control and optimization of the overall integrated structure with varying considerations such as: the desired ratio of the width to length in order to meet UCI and other requirements; the amount of storage space in the container; the rigidity of the handlebars; optimal aerodynamic properties of the combination; etc.
As mentioned above, one example embodiment contemplates the incorporation of the storage unit 105 directly into the handlebar unit 120. In this embodiment, the storage unit may comprise a bladder of sorts made from a malleable material such as rubber, plastic, cloth, animal or other organic material, or any combination thereof. The contents of the storage unit 105 may further be accessed by any well know mechanism such previously described such as a zip-lock sealer, zipper, cap, suction device, etc. On the other hand, accessing the storage unit within the handlebar section 120 may be done by a flap or door within the handlebar unit, or through access by one of the ends of the handlebars. Alternatively, the storage container 105 might be accessed through a sliding section of the bar that reveals the storage container therein. Of course, many other well know ways of incorporating a storage device within a generally solid unit are contemplated herein and the above gives merely some examples of mechanisms used in accessing the storage container and its contents when integrated internally within a handlebar system. For example, the storage unit may not necessarily have a separate bladder part as described above, but simply be formed within the handlebar section. As such, the above description of the storage unit internally formed within the handlebar system and the mechanisms for accessing such is used for illustrative purposes only and is not meant to limit or otherwise narrow the scope of the present invention unless otherwise explicitly claimed.
Further, other embodiments compensate or reduce the appearance of the discontinuity formed between the storage containment unit 105 and the handlebar 120 section by using aerodynamic trip edges or cusps formed in the container unit, handlebars system, or both. A correctly shaped trip edge or cusp, encourages a standing vortex, which advantageously creates a virtual surface of continuity between the storage container and the handlebars. For example, the use of a trip edge at the training edge of the containment unit promotes a favorable pressure gradient that acts as the extension of the container, further integrating it with the handlebar system. Similarly, the s cusp shape can be used like a flow trip to promote flow reattachment in a favorable pressure gradient, which will make the container less sensitive to changes in handlebar diameters or changes in wind conditions with varied levels of turbulence.
In other words, by making forming a trip edge or cusp at the trailing or other desired section of the containment unit, a trip flow causes a circulation or vortex in the area of discontinuity, which forms a smoother virtual surface for the flow field. This generates a low pressure, which will help flow attachment and reduce drag. Further, the virtual profiled integrated storage container and handlebar system helps control flow without the necessity of designed integration and manufacturing of either the storage container with the handlebar unit, or vise versa. In other words, the ability to provide a virtual or seamless integration of the storage container and handlebars enhances the desirability of the use of described embodiments of the present without regard to the type of handlebar system used. As such, example embodiments contemplate using any standard form of handlebars, e.g., those shown in
Other embodiments also consider other design factors in optimizing performance with UCI and non-UCI regulations. For example, as shown in
Without regard to other design considerations noted herein, other example embodiments provide for various forms of attachment mechanisms for securing the storage container 105 to the handlebar 120 system. Although example embodiments generally consider attachment types for easy removal and reattachment of the storage container 105 to the handlebar system 120, other example embodiments allow for more tightly affix the container to the handlebar unit.
For example, as shown in
On the other hand, example embodiments also consider the case were frequent removal of the storage container is preferred, which generally means less secure or stable attachment. For instance, if he storage unit are water bottles with flip caps or other opening mechanisms for drinking the contents thereof, then ease in removing (and reattaching) the bottle will generally be desirable. Accordingly, such attachment mechanisms may include, without limitation: magnets; Velcro; clips; snaps; grooved guides or channels; adhesive tape or glue; prongs; or other hardware. Of course, any combination of the attachment mechanisms is also contemplated herein.
In yet another example embodiment, the storage container may be adjustable relative to the handlebar unit in order to divert airflow as desired. For example, the storage container 105 may be fitted at an angle to allow airflow around the handlebar unit. In such embodiment, the rotation of the storage unit provides essentially a turning vane to move the flow of air towards or away from a rider or other parts of the cycling unit. Such airfoil adjustment allows for the reduction of the overall system drag or may serve to simply provide a rider with additional air-cooling when needed.
Still other example embodiment provide for the integration of the attachment mechanism with the storage container, handlebar system, or both. For example, as illustrated in
Note that many types of materials and combinations thereof are considered in forming the integrated storage container and handlebar system herein described. For example, the storage container may be made from polyurethane or other plastic materials, fiberglass material, metals and alloys, carbon fiber, or any other suitable material and combinations thereof. Further, the materials may be of a disposable form for a single use, or a more durable, long lasting material. Of course, the above gives a brief example of the many types of materials used in forming example embodiments described herein; and therefore, it is not meant to limit or otherwise narrow the scope of the present invention unless otherwise specifically claimed.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
