Abstract
Description
La présente invention concerne une table destinée a recevoir l'équipement optique d'un iridoscope ctest-à-dire, colonne, blocs crémailleres, microscope et éclairage, cet équipement étant susceptible d'être déplacé à fin de réglage, selon deux directions orthogonales d'un plan horizontal. The present invention relates to a table intended to receive the optical equipment of an iridoscope, that is to say, column, rack blocks, microscope and lighting, this equipment being capable of being moved at the end of adjustment, in two orthogonal directions d 'a horizontal plane.
Dans les dispositifs connus de ce genre, les glissières sont généralement constituées par des pièces usinées en queue d'aronde ou en forme de T
Ces dispositifs sont excellents mécaniquement, mais ils sont lourds et coûteux. Ils conviennent parfaitement aux bancs de machines outils par exemple où une grande précision est requise, mais pour des usages d'une moins grande précision, leur coût est prohibitif.In known devices of this kind, the slides are generally constituted by parts machined in dovetail or in the shape of a T
These devices are excellent mechanically, but they are heavy and expensive. They are perfectly suited to machine tool benches for example where high precision is required, but for uses of less precision, their cost is prohibitive.
Certains autres dispositifs utilisent des glissières cylindriques à billes comme dans le guidage des porte outils de presse par exemple. Ces glissières sont également assez coûteuses et leur montage nécessite un encombrement non négligeable
La table selon l'invention évite ces inconvénients. Elle permet d'allier un montage d'encombrement très réduit à une bonne rigidité pour un gain de poids considérable, et présente une grande souplesse d'utilisation.Some other devices use cylindrical ball bearings as in guiding press tool holders for example. These slides are also quite expensive and their assembly requires a considerable space.
The table according to the invention avoids these drawbacks. It allows a very compact assembly to be combined with good rigidity for a considerable weight gain, and has great flexibility of use.
La table selon l'invention comprend un socle fixe en tôle pliée sur quatre côtés et soudée dans les angles pour assurer une bonne rigidité, et deux plateaux mobiles. Selon les besoins, ces plateaux pourront être soit en tole pliée, soit usinés dans un alliage léger par exemple. Ces plateaux sont liés entre eux et avec la table par deux jeux de deux glissières a billes parallèles entre elles, chaque jeu étant fixé de part et d'autre du plateau central suivant deux directions orthogonales. The table according to the invention comprises a fixed sheet metal base folded on four sides and welded in the corners to ensure good rigidity, and two mobile trays. Depending on requirements, these plates can either be made of folded sheet or machined from a light alloy for example. These plates are linked together and with the table by two sets of two parallel ball slides, each set being fixed on either side of the central plate in two orthogonal directions.
Selon l'invention les glissières à billes utilisées sont constituées par deux profils en alliage léger. Le profil interne nommé ici "mâle" est de section rectangulaire et comporte sur chacun de ses petits cotés une gorge semi circulaire pour le passage des billes. Le profil externe ici nomme "femelle" est en forme de U, l'intérieur des ailes de 1'U comportant également une gorge semi circulaire pour le passage des mêmes billes. De la sorte, le profil femelle vient coiffer le profil male avec interposition d'un certain nombre de billes montées en cage libre. Ces glissières sont d'un modèle courant dans le commerce. Habituellement elles sont utilisées dans une position telle que la plus grande dimension de leur section rectangulaire se situe dans un plan vertical.Selon l'invention ces glissières sont utilisées à plat c'est-à-dire dans une position perpendiculaire à leur position habituelle. De cette façon, l'encombrement est minimal. La capaci té de charge est évidemment réduite mais néanmoins suffisante pour beaucoup d'utilisations. According to the invention, the ball slides used consist of two light alloy profiles. The internal profile named here "male" is of rectangular section and comprises on each of its short sides a semi circular groove for the passage of the balls. The external profile here called "female" is U-shaped, the inside of the wings of the U also comprising a semi-circular groove for the passage of the same balls. In this way, the female profile covers the male profile with the interposition of a certain number of balls mounted in a free cage. These slides are a common model in trade. Usually they are used in a position such that the largest dimension of their rectangular section is located in a vertical plane. According to the invention these slides are used flat, that is to say in a position perpendicular to their usual position. In this way, the space is minimal. The load capacity is obviously reduced, but nevertheless sufficient for many uses.
Par ailleurs, la partie femelle se trouve à la partie supérieure de façon à éviter l'introduction de poussières. Furthermore, the female part is located at the top so as to avoid the introduction of dust.
Le jeu peut être limité par le constructeur par un choix judicieux du diamètre des billes. Des butées peuvent également être prévues pour limiter les courses de chacun des plateaux ainsi que des vis d'immobilisation des plateaux les uns par rapport aux autres. The play can be limited by the manufacturer by a judicious choice of the diameter of the balls. Stops can also be provided to limit the strokes of each of the plates as well as screws for immobilizing the plates with respect to each other.
Le dessin annexé représente en perspective une application de ce dispositif à la réalisation d'un support d'indoscope. The accompanying drawing shows in perspective an application of this device to the production of an indoscope support.
L socle 1 supporte les glissières 4 qui sont liées d'une part à ce socle par leur partie malte, d'autre part au plateau 2 par leur partie femelle. The base 1 supports the slides 4 which are linked on the one hand to this base by their malt part, on the other hand to the plate 2 by their female part.
Le plateau 2 supporte à sa partie supérieure le plateau 3 grâce au jeu de glissières 5 dont la direction est perpendiculaire au jeu de glissières 4. Des vis de blocage 6 et 7 permettent l'immobilisation des plateaux dans une position choisie. Dans le cas particulier du support représenté, S est une colonne qui, grâce à un embout fileté, vient se visser sur le plateau 3. Elle est destinée à recevoir un microscope bino culaire. Les montants 9 sont maintenus en position dans les trous 11 du socle 1 grâce aux vis 10. Ces montants sont destinés à recevoir une mentionnière et un support frontal permettant l'appui de la tête du patient. The plate 2 supports at its upper part the plate 3 thanks to the set of slides 5 whose direction is perpendicular to the set of slides 4. Locking screws 6 and 7 allow the trays to be immobilized in a chosen position. In the particular case of the support shown, S is a column which, thanks to a threaded endpiece, is screwed onto the plate 3. It is intended to receive a bino cular microscope. The uprights 9 are held in position in the holes 11 of the base 1 by means of the screws 10. These uprights are intended to receive an anchor and a front support allowing the support of the patient's head.
Le dispositif objet de l'invention permet la réalisation d'un suPport démontable pour iridoscope. Il allie à la légèreté une bonne rigidite et une grande souplesse d'utilisation. Le même dispositif pourra être utilisé avantageusement pour tout matériel demandant un déplacement manuel sensitif (matériel médical) ainsi que pour le déplacement rapide de petites pièces à percer sur une perçeuse sensitive légère. The device object of the invention allows the realization of a removable suPport for iridoscope. It combines lightness with good rigidity and great flexibility of use. The same device can be used advantageously for any material requiring a sensitive manual movement (medical material) as well as for the rapid displacement of small parts to be drilled on a light sensitive drill.
