DESCRIPTION DESCRIPTION
Domaine de l'invention Field of the invention
L'invention concerne la remise à neuf des surfaces dures, notamment des vitres et tous les éléments qui comportent du verre, tels que les portes vitrées, les façades, et, de manière générale, toutes les surfaces en matériaux durs susceptibles d'être rayées, ou dont la surface est endommagée, ou comportant des traces difficiles à enlever. The invention relates to the refurbishment of hard surfaces, especially panes and all elements that include glass, such as glass doors, facades, and, in general, all surfaces of hard materials that may be scratched , or whose surface is damaged, or with traces that are difficult to remove.
Art antérieur et problème posé Prior art and problem
De nombreux éléments, notamment verticaux, constituant une partie des bâtiments, ou de l'immobilier en général, sont constitués de parois en verre, ou de vitres, qui peuvent être rayées au court du temps. Les utilisateurs éprouvent, dans la plupart des cas, le désir de les restaurer, ces éléments constituants des vitrines, et devant, entre autres, contribuer à l'effet attractif et commercial. Many elements, including vertical, constituting part of buildings, or real estate in general, consist of glass walls, or windows, which can be scratched over time. In most cases, the users feel the desire to restore them, these elements constituting the windows, and having to, inter alia, contribute to the attractive and commercial effect.
Différents systèmes de ponçage ou de meulage de vitres existent, mais ne donnent pas entière satisfaction, notamment vis-à-vis du maniement de l'appareil qui peut s'avérer relativement lourd pour l'opérateur, ce maniement devant rester très précis pour ne pas entamer la vitre ou le verre, ou de manière générale, la surface à poncer.  Various sanding or glass grinding systems exist, but are not entirely satisfactory, particularly with respect to the handling of the apparatus which may be relatively heavy for the operator, this handling having to remain very precise in order to do not break the glass or glass, or in general, the surface to be sanded.
Pour remédier à cet inconvénient, il a déjà été créé des systèmes de meulage comportant un support fixé sur la vitre pour pouvoir supporter le poids du dispositif de meulage comportant, entre autre, un moteur électrique, et une meule ; ceci pour faciliter le maniement par l'opérateur et affiner le résultat attendu. A cet effet, on peut citer la demande de brevet européen EP 1 827 755 de la Société VETROX et un système mis en œuvre par le Déposant. To remedy this drawback, grinding systems have already been created comprising a support fixed on the window to be able to support the weight of the grinding device comprising, inter alia, an electric motor, and a grinding wheel; this to facilitate handling by the operator and refine the expected result. For this purpose, mention may be made of the European patent application EP 1 827 755 of the VETROX Company and a system implemented by the Applicant.
En référence à la figure 1, ce dernier comprend principalement un premier organe de support constitué d'une barre supérieure cylindrique 11 horizontale et supérieure, fixée sur la vitre par deux ventouses 15S, fixées chacune à une extrémité de ce premier organe de support 11, horizontal et supérieur. De préférence et parallèlement, il comprend un troisième organe de support formé par un rail inférieur 14, horizontal et inférieur, fixé lui-même également au moyen de deux ventouses 151, aux deux extrémités de ce rail inférieur 14 qui est horizontal. Ainsi, grâce à un premier organe de liaison 16, un deuxième organe de support vertical formé d'une ou de barres parallèles 12 et 13, peut coulisser transversalement. Ces dernières supportent un dispositif de meulage 2 monté coulissant verticalement sur ces barres parallèles 12 et 13, un moteur 23 étant placé de côté distal par rapport à la vitre, c'est-à-dire aux ventouses 15S et 151. Il entraîne un disque de meulage 26 fixé sur un arbre rotatif 25 qui se trouve en regard de la vitre et qui constitue l'outil opérationnel pour meuler la vitre, ou la surface à meuler. L'extrémité inférieure des deux barres verticales 12 et 13 constituant le deuxième organe de support prend appui sur le rail inférieur 14 constituant le troisième organe de support, ceci au moyen d'une paire de roulettes inférieures.  With reference to FIG. 1, the latter mainly comprises a first support member consisting of a horizontal upper and upper cylindrical bar 11 fixed to the window glass by two suckers 15S, each attached to one end of this first support member 11, horizontal and superior. Preferably and in parallel, it comprises a third support member formed by a bottom rail 14, horizontal and lower, itself also fixed by means of two suckers 151 at both ends of the lower rail 14 which is horizontal. Thus, thanks to a first connecting member 16, a second vertical support member formed of one or parallel bars 12 and 13, can slide transversely. The latter support a grinding device 2 mounted vertically sliding on these parallel bars 12 and 13, a motor 23 being placed distal to the window, that is to say the suction cups 15S and 151. It drives a disc grinding device 26 fixed on a rotary shaft 25 which is opposite the window and which constitutes the operational tool for grinding the window, or the surface to be grinded. The lower end of the two vertical bars 12 and 13 constituting the second support member is supported on the lower rail 14 constituting the third support member, this by means of a pair of lower rollers.
Or, le second organe de support vertical est monté pivotant autour du premier organe de support supérieur et horizontal, de manière à pouvoir écarter le disque de meulage 26 de la surface, lorsque l'usinage doit être arrêté. L'opérateur doit alors tirer sur le dispositif de meulage 2, au moyen des deux poignées 24, qui lui servent à appliquer le disque de meulage 26 contre la vitre à meuler. Il s'ensuit un risque d'arrachage des ventouses supérieures 15S, en cas de traction trop importante de l'opérateur sur ces poignées 24. En d'autres termes, le positionnement en distance de cet ensemble de ce dispositif de meulage 2 par rapport à la vitre ne dépend entièrement que de l'habileté de l'opérateur et de sa force. De plus, cette opération d'arrêt du meulage, par exemple à la fin d'un mouvement horizontal ou vertical, est fréquente. Le but de l'invention est donc de faciliter la tâche de l'opérateur, notamment dans les mouvements d'application et de retrait du disque de meulage 26, vis-à-vis de la vitre. Objet de l'invention However, the second vertical support member is pivotally mounted around the first upper and horizontal support member, so as to move the grinding disc 26 away from the surface, when the machining must be stopped. The operator must then fire on the grinding device 2, by means of the two handles 24, which serve to apply the grinding disc 26 against the glass to be grinded. It follows a risk of tearing of the upper suction cups 15S, in case of excessive traction of the operator on these handles 24. In other words, the distance positioning of this assembly of the grinding device 2 relative to to the window depends entirely on the skill of the operator and his strength. In addition, this stop grinding operation, for example at the end of a horizontal or vertical movement, is common. The object of the invention is therefore to facilitate the task of the operator, particularly in the application and removal movements of the grinding disc 26 vis-à-vis the glass. Object of the invention
A cet effet, l'objet principal de l'invention est un des systèmes pour meuler des surfaces dures, de préférence des surfaces en verre, le système comprenant : For this purpose, the main object of the invention is one of the systems for grinding hard surfaces, preferably glass surfaces, the system comprising:

Selon l'invention, l'organe de support du moteur est monté sur le second organe de liaison, de manière à permettre son déplacement relatif, selon une troisième direction Z orthogonale à chacune des premières et secondes directions X et Y, entre une position de retrait et une position de meulage du dispositif de meulage . Selon l'invention, le système comporte également des moyens élastiques de rappel interposés entre l'organe de support du moteur et le second organe de liaison, ces moyens élastiques rappelant l'organe de support du moteur dans sa position de retrait dans une position relâchée du dispositif de meulage. De ce fait, lorsqu'aucune pression n'est exercée contre le dispositif de meulage, en direction de la surface à meuler, ou lorsque cette pression est relâchée, le disque de meulage est écarté de la surface à meuler. According to the invention, the motor support member is mounted on the second connecting member, so as to allow its relative displacement, in a third direction Z orthogonal to each of the first and second directions X and Y, between a position of removal and a grinding position of the grinding device. according to In the invention, the system also comprises elastic return means interposed between the engine support member and the second connecting member, these resilient means recalling the engine support member in its retracted position in a relaxed position of the grinding device. Therefore, when no pressure is exerted against the grinding device in the direction of the surface to be grinded, or when this pressure is released, the grinding disc is moved away from the surface to be grinded.
De préférence, on utilise un troisième organe support s'étendant selon la première direction X et placé parallèlement au premier organe support, ce troisième organe support étant pourvu de ventouses pour sa fixation amovible sur la surface dure à meuler et placées en dessous du premier organe support et sur lequel prend appui une partie inférieure du deuxième organe support.  Preferably, using a third support member extending in the first direction X and placed parallel to the first support member, the third support member being provided with suction cups for its removable attachment to the hard surface to grind and placed below the first member support and on which bears a lower portion of the second support member.
Avantageusement, le second organe de liaison est constitué d'un carter coulissant.  Advantageously, the second connecting member consists of a sliding casing.
Dans la réalisation principale, les moyens élastiques sont constitués par des ressorts de rappel.  In the main embodiment, the elastic means are constituted by return springs.
Il est avantageux d'utiliser deux paires de roulettes supérieures dans le premier organe de liaison, ces deux paires de roulettes étant agencées de part et d'autre du premier moyen de support, en vue de permettre le mouvement longitudinal selon la première direction X du deuxième organe support par rapport au premier organe de support.  It is advantageous to use two pairs of upper rollers in the first connecting member, these two pairs of rollers being arranged on either side of the first support means, in order to allow the longitudinal movement along the first direction X of the second support member relative to the first support member.
Dans ce cas, le premier organe support est constitué avantageusement d'une barre cylindrique contre laquelle roulent les roulettes supérieure et inférieure.  In this case, the first support member advantageously consists of a cylindrical bar against which rolls the upper and lower rollers.
De même, il est avantageux d'utiliser une roulette avant une roulette arrière, montées tournantes sur une partie inférieure du deuxième organe support et destinées à rouler contre le troisième organe support.  Similarly, it is advantageous to use a wheel before a rear wheel, rotatably mounted on a lower portion of the second support member and for rolling against the third support member.
Dans ce cas, le troisième organe support est de préférence un rail inférieur.  In this case, the third support member is preferably a lower rail.

Liste des figures Preferably, the second support member consists of two vertical cylindrical bars on which slides the second connecting member consisting of the sliding housing on which the motor support member is mounted. List of Figures
L'invention et ses différentes caractéristiques techniques seront mieux comprises à la lecture de la description suivante, accompagnée de trois figures représentant respectivement : The invention and its various technical characteristics will be better understood on reading the following description, accompanied by three figures respectively representing:
- figure 1, une vue générale du système destiné à meuler les surfaces dures selon l'invention et selon l'art antérieur ;  - Figure 1, a general view of the system for grinding hard surfaces according to the invention and according to the prior art;

- figure 3, en coupe, ce même dispositif de meulage selon l'invention. Description détaillée d'une réalisation de l'invention En référence aux figures 2 et 3, le dispositif de meulage 2 comprend donc un deuxième organe de liaison sous la forme d'un carter coulissant 21, qui coulisse le long de deux barres verticales 12 et 13 de la figure 1 et qui constituent le deuxième organe de support. On pourrait très bien envisager une seule barre verticale. Sur ce carter coulissant 21, est monté également par coulissement, selon une troisième direction Z orthogonale aux deux premières directions X et Y, l'organe de support moteur 22, qui supporte un moteur 23 actionnant un arbre rotatif 25 destiné à meuler la surface à meuler ou polir. Dans cette réalisation, le carter coulissant 21 possède deux alésages 30 lui permettant de coulisser le long des deux barres verticales 12 et 13. L'arbre rotatif 25 et le disque de meulage 26 sont donc placés à l'opposé du moteur 23. On remarquera, notamment sur la figure 3, que l'axe moteur est donc l'axe de l'arbre rotatif 25 est légèrement incliné par rapport à l'organe de support du moteur 22 et à la troisième direction Z. Ceci permet aux disques de meulage 26 d'attaquer la surface à polir par un seul côté. Cette inclinaison de l'axe moteur est d'environ 2°.  - Figure 3, in section, the same grinding device according to the invention. DETAILED DESCRIPTION OF ONE EMBODIMENT OF THE INVENTION With reference to FIGS. 2 and 3, the grinding device 2 thus comprises a second connecting member in the form of a sliding casing 21, which slides along two vertical bars 12 and 13 of Figure 1 and which constitute the second support member. One could very well consider a single vertical bar. On this sliding case 21 is also slidably mounted, in a third direction Z orthogonal to the first two directions X and Y, the motor support member 22, which supports a motor 23 actuating a rotary shaft 25 for grinding the surface to be machined. grind or polish. In this embodiment, the sliding housing 21 has two bores 30 allowing it to slide along the two vertical bars 12 and 13. The rotary shaft 25 and the grinding disk 26 are therefore placed opposite the motor 23. It will be noted that , especially in Figure 3, that the motor axis is the axis of the rotary shaft 25 is slightly inclined relative to the motor support member 22 and the third direction Z. This allows the grinding discs 26 to attack the surface to be polished by one side. This inclination of the motor axis is about 2 °.
Le débattement entre l'organe de support du moteur 22 et le carter coulissant 21 est faible, c'est-à-dire que l'ordre de quelques centimètres. Deux ressorts de rappel 27, constituants des moyens élastiques, sont placés entre une surface d'appui 28 de l'organe de support du moteur 22 et une surface d'appui 29 du carter coulissant 21. De la sorte, quand l'opérateur appuie sur les deux poignées 24 solidaires de l'organe de support du moteur 22, il abaisse celui-ci du côté de la surface à meuler, de façon à ce que le disque de meulage 26 ponce cette surface. L'opérateur peut alors procéder à des mouvements verticaux, grâce au deuxième organe support constitué par les deux barres verticales 12 et 13, qui permettent des mouvements verticaux du carter coulissant 21 et à des mouvements horizontaux du premier organe de liaison 16 par rapport à la barre supérieure 11. Le premier organe de liaison 16, comprend de préférence deux paires de roulettes qui entourent la barre supérieure 11, permettant ainsi les mouvements horizontaux. Elles permettent également aux barres verticales 12 et 13 de pivoter autour de la barre supérieure 11 pour le montage du système. Lorsque l'opérateur a terminé une passe, il arrête sa pression sur les poignées 24. Les ressorts de rappel 27 font alors leur office en éloignant l'organe de support du moteur 22 du carter coulissant 21, éloignant de quelques centimètres le disque de meulage 26 de la surface à meuler. Une fois que l'opérateur a replacé l'ensemble pour une passe suivante, il reprend sa pression sur les poignées 24 pour que le disque de meulage 26 reprenne contact avec la surface à meuler, afin d'effectuer une nouvelle passe de meulage. The travel between the motor support member 22 and the sliding housing 21 is small, that is to say that the order of a few centimeters. Two springs of recall 27, constituents of the elastic means, are placed between a bearing surface 28 of the motor support member 22 and a bearing surface 29 of the sliding housing 21. In this way, when the operator presses both handles 24 secured to the motor support member 22, it lowers it to the side of the surface to be grinded, so that the grinding disc 26 sanded this surface. The operator can then proceed to vertical movements, thanks to the second support member constituted by the two vertical bars 12 and 13, which allow vertical movements of the sliding housing 21 and horizontal movements of the first connecting member 16 relative to the upper bar 11. The first connecting member 16, preferably comprises two pairs of wheels which surround the upper bar 11, thus allowing horizontal movements. They also allow the vertical bars 12 and 13 to pivot around the upper bar 11 for mounting the system. When the operator has finished a pass, he stops his pressure on the handles 24. The return springs 27 are then done by moving the support member of the motor 22 of the sliding housing 21 away from a few centimeters the grinding disc 26 of the grinding surface. Once the operator has replaced the assembly for a next pass, he resumes his pressure on the handles 24 for the grinding disc 26 to contact the surface to be grinded, in order to perform a new grinding pass.
