DESCRIPTION La présente invention concerne un protège mains démontable fixé au guidon d'une bicyclette de course dont l'utilité est de permettre une pratique plus confortable et plus sûre de ce sport par temps froid. DESCRIPTION The present invention relates to a removable hand guard fixed to the handlebars of a racing bicycle, the utility of which is to allow a more comfortable and safer practice of this sport in cold weather.
En effet, lors de la pratique de ce sport, les doigts des mains sont mal irrigués par la circulation sanguine. Ceci s'explique par le fait que les muscles des mains et des doigts sont statiques, et n'appellent que très peu de sang, par ailleurs mobilisé
par les muscles en effort, ainsi que par la compression des vaisseaux liée à l'appui des mains sur le guidon. Indeed, during the practice of this sport, the fingers of the hands are badly irrigated by the blood circulation. This is explained by the fact that the muscles of the hands and fingers are static, and require only very little blood, which is also mobilized.
by the muscles in effort, as well as by the compression of the vessels linked to the support of the hands on the handlebars.
En période hivernale, le cycliste peut ressentir des douleurs très aiguës notamment s'il présente des difficultés circulatoires. Il se produit aussi une perte de la sensation du toucher, ainsi qu'une difficulté à bouger les doigts, qui peuvent gêner considérablement les actions de freinage et de changement de vitesses, et par conséquent nuire à la sécurité du cycliste. In winter, the cyclist may experience very acute pain, especially if he has circulatory difficulties. There is also a loss of the sensation of touch, as well as difficulty in moving the fingers, which can considerably hamper braking and shifting actions, and consequently jeopardize the safety of the cyclist.
Les effets du froid sont d'autant plus intenses que la vitesse relative de l'air sur les mains est importante. Ce phénomène est encore accru en cas de pluie. The effects of cold are all the more intense the greater the relative speed of the air on the hands. This phenomenon is further increased in the event of rain.
Il n'existe à l'heure actuelle pas de gant à la fois efficace et qui ne gène pas l'utilisation des commandes de frein et de changement de vitesses. There is currently no glove that is both effective and does not interfere with the use of brake and shifting controls.
Des protections souples ou rigides, fixées au guidon, existent dans le domaine de la motocyclette, mais leur mode de fixation ne convient pas à la forme incurvée d'un guidon de bicyclette de course, et leur formes ou principes sont inadaptées à des changements d'appui rapides permettant par exemple au cycliste d'adopter une position de détente. Flexible or rigid protections, fixed to the handlebars, exist in the field of motorcycles, but their method of fixing is not suitable for the curved shape of a handlebar of a racing bicycle, and their shapes or principles are unsuitable for changes in 'quick support allowing for example the cyclist to adopt a relaxed position.
L'objectif de la présente invention est d'apporter une solution au problème de la sensation de froid. Elle permet de limiter la circulation de l'air au niveau du principal point d'appui des mains, et assure ainsi une protection efficace tout en préservant une maniabilité parfaite des mains sur tout le guidon. Elle s'installe ou se dépose très rapidement. The objective of the present invention is to provide a solution to the problem of the sensation of cold. It limits the circulation of air at the main fulcrum of the hands, and thus provides effective protection while preserving perfect maneuverability of the hands on the whole handlebar. It is installed or removed very quickly.
Le dispositif selon l'invention est constitué d'un élément pare brise, maintenu à une distance adéquate de Ja manette de frein par une tige plate et rigide. The device according to the invention consists of a windscreen element, kept at an adequate distance from the brake lever by a flat and rigid rod.
Cette tige est plaquée contre la manette de frein par un lien élastique This rod is pressed against the brake lever by an elastic link
<Desc/Clms Page number 2><Desc / Clms Page number 2>
Selon des modes particuliers de réalisation : - la tige et l'élément pare brise peuvent ne constituer qu'une seule pièce réalisée en matériau plastique par injection. According to particular embodiments: - the rod and the windshield element may constitute only one piece made of plastic material by injection.
- la tige peut être revêtue d'un matériau antiglisse. - the rod can be coated with an anti-slip material.
- elle peut comporter à son extrémité côté guidon un collier avec serrage à vis ou élastique permettant une fixation rigide au guidon. - It may include at its end on the handlebar side a collar with screw or elastic tightening allowing rigid attachment to the handlebars.
- le pare brise peut présenter une dissymétrie selon un axe vertical. - the windshield may have an asymmetry along a vertical axis.
- il peut comporter 2 volets fixes ou orientables. - it can include 2 fixed or adjustable flaps.
- le volet extérieur peut comporter un miroir rétroviseur. - the exterior flap may include a rear-view mirror.
- le pare brise peut être réalisé en matériau plastique transparent ou opaque et coloré, ou bien en fibre de carbone. - the windshield can be made of transparent or opaque and colored plastic material, or of carbon fiber.
- le matériau plastique pourra être incassable pour éviter d'éventuelles blessures par les éclats en cas de chute. - the plastic material may be unbreakable to avoid possible injuries from splinters in the event of a fall.
Les dessins en annexe décrivent l'invention La figure 1 représente l'invention en vue de profil, fixée à la manette de frein. The accompanying drawings describe the invention. FIG. 1 shows the invention in side view, fixed to the brake lever.
La figure 2 la représente de face, La figure 3 représente de profil une variante de la tige de fixation munie d'un collier pour une fixation en plusieurs points au guidon
En référence à ces dessins, le dispositif est composé des éléments suivants : - un élément pare brise (1) en matériau plastique rigide préférentiellement transparent et éventuellement incassable, de surface apparente indicative d'environ 400 cm2, représenté avec 2 volets gauche et droit selon un axe de symétrie vertical. Il est percé de façon à le fixer à la tige plate (2), en un point défini pour que, une fois
installé, il protège au mieux la main. Figure 2 shows it from the front, Figure 3 shows in profile a variant of the fixing rod provided with a collar for fixing at several points to the handlebars
With reference to these drawings, the device is made up of the following elements: - a windscreen element (1) made of rigid plastic material, preferably transparent and possibly unbreakable, with an apparent surface area of approximately 400 cm 2, represented with 2 left and right flaps according to a vertical axis of symmetry. It is drilled so as to fix it to the flat rod (2), at a defined point so that, once
installed, it best protects the hand.
- une tige plate rigide (2) dont une extrémité est pliée à l'équerre et percée. Elle permet de relier le pare brise (1) à la manette de frein (5), elle même fixée au guidon (6). La forme et les dimensions de cette tige (2) sont adaptées aux différents types de manettes de frein ainsi qu'au bon positionnement du protège mains. Elle se glisse du côté extérieur de la manette, entre son revêtement caoutchouc et le corps de celle-ci. Elle est éventuellement recouverte d'un matériau antiglisse, de façon à limiter le déplacement de l'ensemble. Une variante représentée en figure 3 comporte un collier (7) à serrage à vis ou élastique, permettant une fixation en plusieurs points au guidon. - a rigid flat rod (2), one end of which is bent at right angles and pierced. It connects the windshield (1) to the brake lever (5), itself fixed to the handlebars (6). The shape and dimensions of this rod (2) are adapted to the different types of brake levers as well as to the correct positioning of the hand guard. It slides on the outside of the handle, between its rubber coating and the body of the handle. It is possibly covered with an anti-slip material, so as to limit the movement of the assembly. A variant shown in FIG. 3 comprises a collar (7) with screw or elastic clamping, allowing attachment at several points to the handlebars.
