Abstract

The structure is made of bars (7, 8) of square section which have grooves (5) on their faces which are of a "V" shape into which is introduced a bolt (6). The bolt (6) is destined to assure the fixing between the profile (7) and the profile (8). The bolt (6) has fitted on it two threaded holes (9) inclined approximately 45 degrees with respect to the axis of the profile (8) in which are two screws without heads (10). A screw (11) with a head assures the locking of profile (7) against profile (8).

Description

L'invention se rapporte aux structures en barres profilées qui constituent les bâtis de machine ou tables de travail, entre autres. The invention relates to profiled bar structures which constitute machine frames or work tables, among others.

Ces barres profilées sont obtenues par filage à la presse d'alliage léger. La forme extérieure de ces barres est généralement carré, mais elles peuvent aussi, par l'assemblage d'au moins deux carrés, former un rectangle ou d'autres figures plus complexes. La section intérieure d'un carré est constituée généralement figure 1, d'une âme centrale (1) percée d'un trou (2), de laquelle partent quatre nervures (3) vers les angles en forme de cornière dont les bras (4), constituent deux à deux les rainures longitudinales (5), lesquelles sont principalement destinées à recevoir les dispositifs de fixation.These profiled bars are obtained by spinning with a light alloy press. The external shape of these bars is generally square, but they can also, by the assembly of at least two squares, form a rectangle or other more complex figures. The inner section of a square generally consists of Figure 1, a central core (1) pierced with a hole (2), from which four ribs (3) leave towards the angles in the form of an angle whose arms (4 ), constitute two by two the longitudinal grooves (5), which are mainly intended to receive the fixing devices.

Pour constituer une structure les barres profilées sont assemblées entre elles à l'aide de pièces spécifiques introduites dans les rainures longitudinales, vissées entre elles ou dans les profilés. Ces systèmes sont décrits dans de nombreux brevets tels que : US 3061055, US 3901612,
FR 7828501 ou FR 7924707, pris à titre d'exemple non limitatifs, ces dispositifs nécessitent généralement un usinage relativement important des barres profilées et, lorsque les profilés sont assemblés par l'intermédiaire des pièces d'assemblage, la structure manque de rigidité. L'assemblage peut être réalisé aussi par vissage direct dans les profilés dans un taraudage du trou central, brevet FR 84108448.6 issu du brevet Européen 0136431, cet assemblage très simple a cependant l'inconvénient d'une faible rigidité car le serrage n'agit que ponctuellement dans la nervure.To form a structure, the profiled bars are assembled together using specific parts introduced into the longitudinal grooves, screwed together or into the profiles. These systems are described in numerous patents such as: US 3061055, US 3901612,
FR 7828501 or FR 7924707, taken by way of nonlimiting example, these devices generally require relatively large machining of the profiled bars and, when the profiles are assembled by means of the assembly parts, the structure lacks rigidity. The assembly can also be carried out by direct screwing into the profiles in a tapping of the central hole, patent FR 84108448.6 derived from European patent 0136431, this very simple assembly however has the disadvantage of low rigidity because the tightening acts only punctually in the rib.

La présente invention a pour objet de réaliser un assemblage rigide demandant un minimum de préparation des barres profilés. Les buts et les caractéristiques de l'invention apparaissent à la lecture de la description qui suit, en regard des dessins annexés et dans lequels - la figure 1 est une vue de deux barres profilées fixées à angle droit; - la figure 2 est la vue en perspective d'un système de fixation prenant
appui contre une vis; - la figure 3 est coupe du système de fixation de la figure 2; - la figure 4 est la vue en perspective d'un système de fixation prenant
appui dans un trou du profilé; - la figure 5 est une vue en coupe du système précédent; - la figure 6 est une vue du système de fixation servant de gabarit; - la figure 7 est une vue en coupe d'un système de fixation prenant
appui directement contre le profilé. The object of the present invention is to produce a rigid assembly requiring a minimum of preparation of the profiled bars. The objects and characteristics of the invention appear on reading the description which follows, with reference to the appended drawings and in which - FIG. 1 is a view of two profiled bars fixed at right angles; - Figure 2 is the perspective view of a fixing system taking
support against a screw; - Figure 3 is a section of the fastening system of Figure 2; - Figure 4 is the perspective view of a fixing system taking
support in a hole in the profile; - Figure 5 is a sectional view of the previous system; - Figure 6 is a view of the fixing system serving as a template; - Figure 7 is a sectional view of a fixing system taking
support directly against the profile.

Le but de l'invention est de bloquer fortement figure 1, à l'aide du verrou (6), une des faces du profilé (7) contre une extrémité du profilé (8). Pour cela le verrou (6) figure 2, dont la section correspond aux rainures longitudinales échancrées (5) des profilés de telle sorte qu'il puisse s'y introduire avec un certain jeu, deux trous filetés (9) inclinés d'environ 450 par rapport à l'axe du profilé débouchent dans le trou central fraisé (23). Dans ces filetages fig. 3 deux vis sans tête (10), qui prennent appui contre une vis à tête fraisée (11) logée dans le trou (23) et vissée dans le trou (2) fileté de l'âme centrale (1) du profilé (8), poussent le verrou (6) dans le sens des flèches A bloquant ainsi le profilé (7) contre le profilé (8). The object of the invention is to strongly block Figure 1, using the latch (6), one of the faces of the profile (7) against one end of the profile (8). For this the lock (6) Figure 2, whose section corresponds to the indented longitudinal grooves (5) of the profiles so that it can be inserted with a certain play, two threaded holes (9) inclined by about 450 relative to the axis of the profile open into the milled central hole (23). In these threads fig. 3 two headless screws (10), which bear against a countersunk head screw (11) housed in the hole (23) and screwed into the hole (2) threaded in the central core (1) of the profile (8) , push the latch (6) in the direction of the arrows A thus blocking the profile (7) against the profile (8).

Une variante de construction sur le même principe est représentée figure 4. Le verrou (12) a une forme en U dont les deux bras (13) et la partie centrale (14) ont une section qui s'adapte aux rainures (5) des profilés de telle sorte qu'ils puissent s'y introduire avec un certain jeu. Les bras (13), représentés en coupe figure 5, possèdent des trous filetés (15) inclinés d'environ 300 par rapport à l'axe du profilé. Dans ces filetages deux vis sans tête (16) qui prennent appui dans le perçage (17) contre l'amie centrale (1) du profilé (18), tirent le verrou (12) dans le sens des flèches B, bloquant ainsi le profilé (19) contre le profilé (18). A variant construction on the same principle is shown in FIG. 4. The lock (12) has a U shape, the two arms (13) and the central part (14) of which have a section which adapts to the grooves (5) of the profiles so that they can be inserted with a certain play. The arms (13), shown in section in FIG. 5, have threaded holes (15) inclined by about 300 relative to the axis of the profile. In these threads two grub screws (16) which bear in the bore (17) against the central friend (1) of the profile (18), pull the latch (12) in the direction of the arrows B, thus blocking the profile (19) against the profile (18).

La précision de positionnement pour le perçage du trou (17), peut être résolue par un trou (20) figure 6, réalisé dans le verrou (21) à une distance déterminée, le verrou sert alors de gabarit de perçage. The positioning precision for drilling the hole (17) can be resolved by a hole (20) in FIG. 6, produced in the latch (21) at a determined distance, the latch then serves as a drilling template.

Une autre variante de construction est représentée figure 7, les vis (22) possèdent une partie non filetée formant téton dont le bout peut être droit ou concave, le vissage des vis (22) fait pénétrer le téton dans l'âme du profilé (18) y prend appui pour tirer le verrou (21) dans le sens des flèches B, assurant ainsi le bloquage des profilés. Another construction variant is shown in FIG. 7, the screws (22) have a non-threaded part forming a stud, the end of which can be straight or concave, the screwing of the screws (22) causes the stud to penetrate into the core of the profile (18 ) is supported therein to pull the lock (21) in the direction of the arrows B, thus ensuring the blocking of the profiles.

Le bloquage est réalisé par les verrous (6), (12) ou (21) sur toute leur largeur qui correspond à la largeur des profilés (8) ou (18) ce qui assure le maximum de rigidité aux assemblages. The blocking is achieved by the latches (6), (12) or (21) over their entire width which corresponds to the width of the profiles (8) or (18) which ensures maximum rigidity in the assemblies.

Le montage des verrous (6) (12) ou (21) sur les profilés (8) ou (17) avant assemblage de ceux-ci sur les profilés (7) ou (19), facilite le règlage et l'assemblage quand les structures sont complexes. The mounting of the latches (6) (12) or (21) on the profiles (8) or (17) before assembly of these on the profiles (7) or (19), facilitates adjustment and assembly when the structures are complex.

La forme des verrous permet leur fabrication par moulage sous pression d'alliages légers ou encore par injection de matière thermoplastique à haute caractéristique mécanique.  The shape of the locks allows them to be manufactured by die-casting of light alloys or by injection of thermoplastic material with high mechanical characteristics.
