Description

Repose-poignet pour utilisation de souris d'ordinateur ou de clavier Wrist rest for using computer mouse or keyboard
La présente invention concerne un accessoire, désigné comme repose-poignet, qui a pour but de répondre ergonomiquement au problème des fatigues et lésions liées à l'utilisation prolongée des souris d'ordinateur, ou la frappe sur un clavier information ou autre.The present invention relates to an accessory, designated as a wrist rest, which aims to respond ergonomically to the problem of fatigue and injuries related to prolonged use of computer mice, or typing on an information keyboard or the like.
Les repose-poignet existants sont des accessoires de forme et taille diverses, indépendants ou liés à un tapis de souris ou à un clavier, qui se présentent en général comme de simples "coussins" de gel ou de mousse, sur lesquels l'utilisateur de la souris d'ordinateur ou du clavier peut poser sa main, son poignet ou son avant-bras. Ce repose-poignet peuvent notamment posséder la forme d'une barrette rectiligne, se plaçant devant un clavier, ou encore une forme plus ramassée en croissant. A titre d'exemples, il est ici fait référence aux documents US 5730711 , US 6048325 et WO 98/20775. De tels repose-poignet possèdent divers inconvénients ou insuffisances.The existing wrist rests are accessories of various shape and size, independent or linked to a mouse pad or a keyboard, which generally appear as simple "cushions" of gel or foam, on which the user the computer mouse or keyboard can place his hand, wrist or forearm. This wrist rest can in particular have the shape of a rectilinear bar, placed in front of a keyboard, or even a shape more gathered in crescent. By way of example, reference is made here to documents US 5730711, US 6048325 and WO 98/20775. Such wrist rests have various drawbacks or inadequacies.
En premier lieu, la pose du poignet ou de l'avant-bras sur ces accessoires s'effectue exactement à l'endroit ou passent les veines et les tendons, qui assurent la circulation sanguine et les mouvements de la main, et où se trouve aussi le canal carpien. L'appui de cette zone du poignet entraîne donc un manque de circulation du sang, d'où refroidissement et fourmillement, ainsi qu'une gêne dans les mouvements, d'où des risques de lésions (tendinite, lésions du canal carpien).First, the wrist or forearm is placed on these accessories exactly where the veins and tendons pass, which provide blood circulation and hand movements, and where is also the carpal tunnel. The support of this area of the wrist thus involves a lack of circulation of the blood, from where cooling and tingling, as well as a discomfort in the movements, from where risks of lesions (tendinitis, lesions of the carpal tunnel).
Par ailleurs, les repose-poignet existants étant immobilisés, soit par leur liaison au clavier ou au tapis de souris, soit par leur adhérence sur la surface d'un bureau s'ils sont conçus comme des accessoires indépendants, les mouvements de la main de l'utilisateur, qu'il s'agisse de mouvements latéraux (de droite à gauche ou inversement) ou de mouvements angulaires, se font avec des frottements du poignet sur la surface supérieure desdits repose- poignet. En plus de la gêne qu'ils peuvent occasionner, ces frottements peuvent causer des irritations ou des réactions allergiques.In addition, the existing wrist rests being immobilized, either by their connection to the keyboard or the mouse pad, or by their adhesion to the surface of a desk if they are designed as independent accessories, the movements of the hand of the user, whether lateral movements (from right to left or vice versa) or angular movements, are carried out with wrist friction on the upper surface of said wrist rests. In addition to the discomfort they can cause, this friction can cause irritation or allergic reactions.
Enfin, tous les repose-poignet existants sont dépourvus d'un système de réglage qui permettrait de les adapter, notamment en hauteur, à l'ergonomie des bureaux, souris et claviers, ce qui ne peut qu'augmenter encore la fatigue de l'utilisateur. L'invention vise donc à éviter les inconvénients et insuffisances des produits existants dans ce domaine et elle a donc pour but de fournir un repose-poignet apportant une solution particulièrement ergonomique et adaptée, notamment pour éviter à l'utilisateur des fatigues et des risques de lésions, surtout en cas d'utilisation prolongée, et avec des possibilités de réglage pour une meilleure adaptation à l'utilisateur.Finally, all existing wrist rests do not have an adjustment system that would allow them to be adapted, in particular in height, to the ergonomics of desks, mice and keyboards, which can only further increase the fatigue of the user. The invention therefore aims to avoid the drawbacks and inadequacies of existing products in this field and it therefore aims to provide a wrist rest providing a particularly ergonomic and suitable solution, in particular to avoid the user from fatigue and risks of injuries, especially in case of prolonged use, and with adjustment possibilities for a better adaptation to the user.
A cet effet, l'invention a pour objet un repose-poignet pour utilisation de souris d'ordinateur ou de clavier, qui se compose essentiellement d'une surface de base, prévue pour être posée et déplacée sur une surface horizontale, et de deux éléments d'appui latéraux, montés sensiblement parallèlement l'un à l'autre au-dessus de la surface de base, à un certain écartement l'un de l'autre, et prévus pour l'appui du poignet ou de l'avant-bras de l'utilisateur.To this end, the subject of the invention is a wrist rest for using a computer mouse or a keyboard, which essentially consists of a base surface, intended to be placed and moved on a horizontal surface, and two lateral support elements, mounted substantially parallel to each other above the base surface, at a certain distance from each other, and provided for supporting the wrist or the front - user arm.
Avantageusement, la surface de base porte des patins à faible coefficient de frottement, ou constitue elle-même une surface à faible coefficient de frottement, coopérant avec la surface horizontale sur laquelle elle est posée.Advantageously, the base surface carries pads with low coefficient of friction, or itself constitutes a surface with low coefficient of friction, cooperating with the horizontal surface on which it is placed.
Selon un mode de réalisation de l'invention, les deux éléments d'appui latéraux sont des éléments allongés, du genre coussins, montés parallèlement l'un à l'autre sur une embase commune, dont la partie inférieure constitue ladite surface de base.According to one embodiment of the invention, the two lateral support elements are elongated elements, of the cushion type, mounted parallel to one another on a common base, the lower part of which constitutes said base surface.
De préférence, le repose-poignet objet de l'invention comporte des moyens pour le réglage en hauteur des deux coussins ou éléments d'appui latéraux. Dans une forme de réalisation particulière, ces moyens de réglage sont constitués par une réalisation de l'embase précitée en deux parties, avec une partie inférieure et une partie supérieure qui présentent à leur périphérie des filetages complémentaires, le vissage plus ou moins profond d'une partie dans l'autre permettant de faire varier la hauteur de l'embase, donc la hauteur à laquelle se situent les deux coussins ou éléments d'appui latéraux, montés sur la partie supérieure de ladite embase. De préférence, le repose-poignet, objet de l'invention, comporte encore des moyens pour le réglage de l'écartement des deux coussins ou éléments d'appui latéraux. Selon un mode d'exécution particulier, ces moyens de réglage d'écartement comprennent, d'une part, une glissière en forme de ligne refermée sur elle-même, ménagée dans la partie supérieure de l'embase, et d'autre part, des éléments de guidage prévus à la base des coussins ou éléments d'appui latéraux et engagés de manière coulissante dans la glissière, cette dernière possédant un tracé symétrique par rapport au centre de la partie supérieure de l'embase, avec diverses portions de glissière plus ou moins éloignées de ce centre, définissant ainsi au moins deux valeurs d'écartement distinctes pour les coussins ou éléments d'appui latéraux. Dans un autre mode de réalisation, permettant lui aussi un réglage d'écartement des deux éléments d'appui latéraux, l'un de ces éléments est lié axialement à une tige filetée, qui traverse un trou taraudé correspondant de l'autre élément d'appui latéral, ce qui permet un réglage d'écartement par vissage d'un élément d'appui latéral relativement à l'autre. Dans ce dernier cas, les parties inférieures respectives des deux éléments d'appui constituent elles-mêmes la surface de base, à la manière de pieds, et aucune embase séparée n'est nécessaire.Preferably, the wrist rest object of the invention comprises means for adjusting the height of the two cushions or lateral support elements. In a particular embodiment, these adjustment means consist of an embodiment of the aforementioned base in two parts, with a lower part and an upper part which have complementary threads at their periphery, the more or less deep screwing of one part in the other making it possible to vary the height of the base, therefore the height at which the two cushions or lateral support elements are located, mounted on the upper part of said base. Preferably, the wrist rest, object of the invention, further comprises means for adjusting the spacing of the two cushions or lateral support elements. According to a particular embodiment, these spacing adjustment means comprise, on the one hand, a line-shaped slide closed on itself, formed in the upper part of the base, and on the other hand, guide elements provided at the base of the side cushions or support elements and slidably engaged in the slide, the latter having a symmetrical layout relative to the center of the upper part of the base, with various slide portions more or less distant from this center, thus defining at least two distinct spacing values for the cushions or support elements side. In another embodiment, also allowing adjustment of the spacing of the two lateral support elements, one of these elements is connected axially to a threaded rod, which passes through a corresponding tapped hole in the other element lateral support, which allows a spacing adjustment by screwing a lateral support element relative to the other. In the latter case, the respective lower parts of the two support elements themselves constitute the base surface, in the manner of feet, and no separate base is necessary.
Dans l'ensemble, il est ainsi obtenu un repose-poignet perfectionné, qui possède les avantages suivants : L'appui du poignet ou de l'avant-bras de l'utilisateur se fait sur deux coussins ou éléments d'appui latéraux, de préférence réglables en écartement, de telle sorte que cet appui est localisé au niveau des deux os de l'avant-bras, qui sont le radius et le cubitus. L'appui ainsi réalisé libère totalement les veines, les tendons et le canal carpien, qui se situent "en l'air", entre les deux coussins ou éléments d'appui.Overall, an improved wrist rest is thus obtained, which has the following advantages: The support of the user's wrist or forearm is carried out on two cushions or lateral support elements, preferably adjustable in spacing, so that this support is located at the level of the two bones of the forearm, which are the radius and the ulna. The support thus produced completely frees the veins, tendons and carpal tunnel, which are located "in the air", between the two cushions or support elements.
Le dispositif de réglage permet d'ajuster Pécartement des deux éléments d'appui latéraux, par simple rotation des deux éléments relativement à l'embase, ou par vissage d'un élément relativement à l'autre, en fonction de la grosseur et/ou de la morphologie des avant-bras, tout en maintenant le parallélisme de ces deux éléments d'appui.The adjustment device makes it possible to adjust the spacing of the two lateral support elements, by simple rotation of the two elements relative to the base, or by screwing of one element relative to the other, depending on the size and / or morphology of the forearms, while maintaining the parallelism of these two support elements.
Si les deux éléments d'appui latéraux sont montés sur une embase pourvue d'un système de réglage en hauteur, la hauteur de l'appui du poignet ou de l'avant-bras est adaptable, en fonction des caractéristiques propres à chaque souris d'ordinateur ou de chaque clavier utilisé. Ce réglage s'effectue lui aussi de façon très simple, par vissage ou dévissage d'une partie de l'embase sur l'autre.If the two lateral support elements are mounted on a base provided with a height adjustment system, the height of the wrist or forearm support is adaptable, according to the characteristics specific to each mouse d computer or each keyboard used. This adjustment is also carried out very simply, by screwing or unscrewing one part of the base on the other.
L'ensemble étant équipé à sa base de patins à faible coefficient de frottement, autrement dit à haut coefficient de glissement, le repose-poignet est facilement déplaçable sur un bureau ou sur un plan de travail, pour suivre les mouvements latéraux ou angulaires de la main, durant le travail. Enfin, la structure symétrique du repose-poignet, et sa large embase ou autre surface de base, assurent sa stabilité, évitant tout basculement.The whole being equipped at its base with skids with low coefficient of friction, in other words with high coefficient of sliding, the wrist rest is easily movable on a desk or on a work surface, to follow the lateral or angular movements of the hand, during work. Finally, the symmetrical structure of the wrist rest, and its wide base or other base surface, ensure its stability, preventing any tilting.
Ainsi, le repose-poignet objet de l'invention s'adapte aussi bien à la morphologie de l'utilisateur qu'au matériau informatique utilisé, de sorte qu'il constitue un produit remarquablement ergonomique, tout en conservant une structure et des réglages simples, ce repose-poignet évitant la fatigue et les lésions, même en cas d'utilisation prolongée d'une souris d'ordinateur ou d'un clavier. L'invention sera mieux comprise à l'aide de la description qui suit, en référence aux dessins schématiques annexés représentant, à titre d'exemples, deux formes d'exécution de ce repose-poignet :Thus, the wrist rest object of the invention adapts as well to the morphology of the user as to the computer material used, so that it constitutes a remarkably ergonomic product, while retaining a structure and simple adjustments. , this wrist rest avoids fatigue and injuries, even in the event of prolonged use of a computer mouse or keyboard. The invention will be better understood with the aid of the following description, with reference to the appended schematic drawings showing, by way of examples, two embodiments of this wrist rest:

Figure 6 est une vue de côté du repose-poignet de la figure 5.Figure 6 is a side view of the wrist rest of Figure 5.
En se référant aux figures 1 à 4, on décrira d'abord une première forme de réalisation du repose-poignet selon l'invention. Comme le montre notamment la figure 1 , ce repose-poignet se compose, d'une manière générale, d'une embase 2 et de deux coussins d'appui latéraux 3 et 4. L'embase 2 possède une forme générale cylindrique.Referring to Figures 1 to 4, we will first describe a first embodiment of the wrist rest according to the invention. As shown in particular in FIG. 1, this wrist rest generally consists of a base 2 and two lateral support cushions 3 and 4. The base 2 has a generally cylindrical shape.
Les deux coussins latéraux 3 et 4, de forme allongée, s'étendent parallèlement l'un à l'autre, et de façon symétrique, au-dessus de l'embase 2 qui leur sert de support. Ces deux coussins 3 et 4 sont réalisables notamment en matière textile, en mousse ou un autre matériau souple analogue, assurant le confort souhaitable. En se référant aussi à la figure 2, le poignet ou l'avant-bras 5 de l'utilisateur prend appui sur les deux coussins latéraux 3 et 4, en prenant place entre ces deux coussins, au-dessus de l'embase 2. En se référant à la figure 3, l'embase 2 du repose-poignet se compose d'une partie inférieure 6 et d'une partie supérieure 7, coaxiales. La partie inférieure 6 présente, à sa périphérie, un filetage intérieur 8. La partie supérieure 7 présente, à sa périphérie, un filetage extérieur 9, complémentaire du filetage intérieur 8 et vissé dans ce dernier. Ainsi, un vissage plus ou moins profond de la partie supérieure 7, dans la partie inférieure 6, permet de faire varier la hauteur H de l'embase 2, donc la hauteur des deux coussins d'appui latéraux 3 et 4.The two lateral cushions 3 and 4, of elongated shape, extend parallel to one another, and symmetrically, above the base 2 which serves as their support. These two cushions 3 and 4 can be produced in particular in textile material, foam or another similar flexible material, ensuring desirable comfort. Referring also to FIG. 2, the user's wrist or forearm 5 is supported on the two lateral cushions 3 and 4, taking place between these two cushions, above the base 2. Referring to Figure 3, the base 2 of the wrist rest consists of a lower part 6 and an upper part 7, coaxial. The lower part 6 has, at its periphery, an internal thread 8. The upper part 7 has, at its periphery, an external thread 9, complementary to the internal thread 8 and screwed into the latter. Thus, a more or less deep screwing of the upper part 7, in the lower part 6, makes it possible to vary the height H of the base 2, therefore the height of the two lateral support cushions 3 and 4.
Sous la partie inférieure 6 de l'embase 2 sont fixés des patins 10 à faible coefficient de frottement (voir figures 2 et 3), par l'intermédiaire desquels le repose-poignet est posé, et peut aisément se déplacer, sur une surface horizontale telle que la surface supérieure d'un bureau, ou tout autre plan de travail.Under the lower part 6 of the base 2 are fixed pads 10 with a low coefficient of friction (see FIGS. 2 and 3), by means of which the wrist rest is placed, and can easily move, on a horizontal surface such as the top surface of a desk, or any other work surface.
Les deux coussins d'appui latéraux 3 et 4 sont montés sur la partie supérieure 7 de l'embase 2, par l'intermédiaire d'un dispositif visible aux figures 3 et 4 qui permet de régler l'écartement E entre les deux coussins 3 et 4. Ce dispositif comprend une glissière 11, en forme de ligne courbe refermée sur elle-même, ménagée sur la face supérieure circulaire de la partie supérieure 7 de l'embase 2. Le tracé de la glissière 11 est symétrique par rapport au centre C de ladite face supérieure, et il comprend diverses portions de glissière, plus ou moins rapprochées ou éloignées du centre C. En particulier, on peut ici distinguer des portions de la glissière 11 rapprochées du centre C, des portions moyennement éloignées du centre C, et des portions plus éloignées du centre C.The two lateral support cushions 3 and 4 are mounted on the upper part 7 of the base 2, by means of a device visible in FIGS. 3 and 4 which makes it possible to adjust the spacing E between the two cushions 3 and 4. This device comprises a slide 11, in the form of a curved line closed on itself, formed on the circular upper face of the upper part 7 of the base 2. The layout of the slide 11 is symmetrical relative to the center C of said upper face, and it comprises various portions of slide, more or less close to or distant from the center C. In particular, we can here distinguish portions of the slide 11 close to the center C, portions moderately distant from the center C, and more distant parts of the center C.
Chaque coussin d'appui latéral 3 ou 4 possède, à sa base, un élément de guidage 12 engagé et retenu dans la glissière 11, et monté coulissant dans cette glissière 11. L'élément de guidage 12 peut notamment se présenter comme un double téton qui, coopérant avec la glissière 11 de profil en "T" renversé, assure une orientation déterminée du coussin 3 ou 4, en chaque point de la glissière 11.Each lateral support cushion 3 or 4 has, at its base, a guide element 12 engaged and retained in the slide 11, and mounted to slide in this slide 11. The guide element 12 can in particular be presented as a double stud which, cooperating with the slide 11 of inverted "T" profile, ensures a determined orientation of the cushion 3 or 4, at each point of the slide 11.
Grâce à ces dispositions, les deux coussins d'appui latéraux 3 et 4 peuvent être amenés, toujours en position symétrique l'un de l'autre par rapport au centre C, sur les diverses portions (plus ou moins rapprochées ou éloignées de ce centre C) de la glissière 11. L'écartement E entre les axes longitudinaux respectifs A et B des deux coussins 3 et 4 est ainsi rendu modifiable. Comme l'illustre la figure 4, cet écartement E peut prendre une valeur relativement faible E1, ou une valeur moyenne E2, ou encore une valeur relativement élevée E3. Par coulissement des éléments de guidage 12 dans la glissière 11, donc par rotation des coussins 3 et 4 relativement à l'embase 2, il est possible de passer d'une valeur d'écartement à une autre.Thanks to these provisions, the two lateral support cushions 3 and 4 can be brought, still in a position symmetrical to one another relative to the center C, on the various portions (more or less close to or distant from this center C) of the slide 11. The spacing E between the respective longitudinal axes A and B of the two cushions 3 and 4 is thus made changeable. As illustrated in FIG. 4, this spacing E can take a relatively small value E1, or an average value E2, or even a relatively high value E3. By sliding the guide elements 12 in the slide 11, therefore by rotation of the cushions 3 and 4 relative to the base 2, it is possible to pass from one spacing value to another.
Ainsi, il est réalisé un repose-poignet réglable en hauteur et en écartement, en ce qui concerne ses deux coussins d'appui latéraux 3 et 4. Les figures 5 et 6 représentent une deuxième forme de réalisation du repose-poignet de l'invention. Le repose-poignet comprend ici deux éléments d'appui latéraux 3 et 4 symétriques, dont l'écartement est réglable par un dispositif du genre vis-écrou. Plus particulièrement, le premier élément d'appui 3 est solidaire d'une tige filetée 13, laquelle est vissée dans un trou taraudé complémentaire 14 ménagé dans le second élément d'appui 4. Ainsi, le vissage ou dévissage d'un élément d'appui 3, par rapport à l'autre élément d'appui 4, permet ici le réglage direct de l'écartement entre ces deux éléments d'appui 3 et 4, pour l'adaptation du repose-poignet à la grosseur et à la morphologie du poignet ou de l'avant-bras de l'utilisateur. Dans le cadre de cette autre forme de réalisation, les figures 5 et 6 illustrent aussi des variantes relatives à la configuration du repose-poignet.Thus, there is provided a wrist rest adjustable in height and in spacing, as regards its two lateral support cushions 3 and 4. FIGS. 5 and 6 show a second embodiment of the wrist rest of the invention . The wrist rest here comprises two symmetrical lateral support elements 3 and 4, the spacing of which is adjustable by a device of the screw-nut type. More particularly, the first support element 3 is integral with a threaded rod 13, which is screwed into a complementary tapped hole 14 formed in the second support element 4. Thus, the screwing or unscrewing of an element of support 3, relative to the other support element 4, here allows direct adjustment of the spacing between these two support elements 3 and 4, for adapting the wrist rest to the size and morphology of the user's wrist or forearm. In the context of this other embodiment, FIGS. 5 and 6 also illustrate variants relating to the configuration of the wrist rest.
Ainsi, les deux éléments d'appui 3 et 4 se composent ici, chacun, d'une pièce rigide, relativement mince, du genre "aile", qui est pourvue localement, dans sa partie supérieure (en position d'utilisation), d'une couche de matière plus souple, respectivement 3a, 4a, prévue pour le contact confortable du poignet ou de l'avant-bras de l'utilisateur. Les pièces rigides peuvent être constituées en matière plastique moulée, rigide, tandis que les couches souples 3a, 4a sont réalisables en mousse ou en caoutchouc. On notera aussi que les parties inférieures respectives 3b, 4b des deux pièces rigides constituent ici elles-mêmes la surface de base, à la manière des pieds, ces parties inférieures 3b, 4b pouvant porter les patins 10 à faible coefficient de frottement (l'embase de la première forme de réalisation n'existant plus). Enfin, il est à noter que, pour laisser la partie supérieure dégagée, la tige filetée 13 relie ici les parties inférieures 3b et 4b des deux éléments d'appui 3 et 4. L'on ne s'éloignerait pas du cadre de l'invention, telle que définie dans les revendications annexées, en modifiant les formes des deux coussins ou éléments d'appui latéraux, notamment pour une meilleure adaptation anatomique, ou en réalisant ces coussins ou éléments d'appui en toute matière appropriée, ou encore en prévoyant des moyens autres, notamment à cames rotatives, pour les réglages de hauteur et d'écartement desdits coussins ou éléments d'appui. Thus, the two support elements 3 and 4 here consist each of a rigid, relatively thin piece, of the "wing" type, which is provided locally, in its upper part (in the use position), d 'A layer of more flexible material, respectively 3a, 4a, provided for the comfortable contact of the wrist or the forearm of the user. The rigid parts can be made of molded, rigid plastic, while the flexible layers 3a, 4a can be made of foam or rubber. It will also be noted that the respective lower parts 3b, 4b of the two rigid parts here themselves constitute the base surface, in the manner of the feet, these lower parts 3b, 4b being able to carry the pads 10 with a low coefficient of friction (the base of the first embodiment no longer existing). Finally, it should be noted that, to leave the upper part unobstructed, the threaded rod 13 here connects the lower parts 3b and 4b of the two support elements 3 and 4. One would not stray from the frame of the invention, as defined in the appended claims, by modifying the shapes of the two side cushions or support elements, in particular for better anatomical adaptation, or by making these cushions or support elements in any suitable material, or by providing other means, in particular with rotary cams, for adjusting the height and spacing of said cushions or support elements.
