Description

Pied de fixation d'un montant
de gardeòrps de balcon.Upright fixing foot
balcony guard.

La présente invention se rapporte à un pied de fixation d'un montant de garde-corps de balcon. The present invention relates to a foot for fixing a balcony railing upright.

Il est connu de fixer les montants des gardes-corps, ou balustrades, de balcon en les enfichant, puis en les verrouillant par serrage, dans des pieds vissés ou scellés préalablement dans la dalle horizontale du balcon. It is known to fix the amounts of railings, or balustrades, balcony by plugging them in, then locking them by tightening, in feet screwed or previously sealed in the horizontal slab of the balcony.

Le serrage des montants dans les pieds qui les reçoivent est effectué classiquement au moyen de coins de serrage qui fonctionnent selon le principe de l'étau. Ces dispositifs ont pour inconvénients d'être relativement complexes et de nécessiter beaucoup de matière autour du pied, de sorte qu'ils sont assez onéreux.Clamping of the uprights in the feet which receive them is conventionally carried out by means of clamping wedges which operate according to the vice principle. These devices have the drawbacks of being relatively complex and of requiring a lot of material around the foot, so that they are quite expensive.

L'invention se rapporte à un dispositif de fixation d'un montant de garde-corps de balcon qui ne présente pas ces inconvénients. Il est constitué par un pied dans lequel vient s'enficher verticalement le montant, ce pied comportant un ou plusieurs trous taraudés horizontaux aptes à recevoir chacun une vis-pointeau, du genre vis bout-cuvette, de préserrage du montant dans le pied. Par ailleurs, sur sa face regardant vers l'intérieur du balcon, ce pied comporte un perçage horizontal apte à recevoir au moins une vis auto-foreuse qui, en forant puis se vissant par auto-taraudage dans le montant assure, après serrage, son verrouillage définitif dans le pied. The invention relates to a device for fixing a balcony railing upright which does not have these drawbacks. It is constituted by a foot in which the upright comes to be inserted vertically, this foot comprising one or more horizontal tapped holes capable of each receiving a needle screw, of the screw-cup type, for pre-clamping the amount in the foot. Furthermore, on its face looking towards the inside of the balcony, this foot has a horizontal bore capable of receiving at least one self-drilling screw which, by drilling and then screwing by self-tapping in the upright ensures, after tightening, its permanent locking in the foot.

De toute façon, l'invention sera bien comprise, et ses avantages et autres caractéristiques ressortiront, au cours de la description suivante d'un exemple non limitatif de réalisation, en référence aux dessins schématiques annexés dans lesquels
Figure 1 est une représentation partielle en perspective d'un garde-corps de balcon équipé de ces pieds de fixation des montants;
Figure 2 est une vue en perspective éclatée de ce pied de fixation
Figure 3 est une coupe verticale selon III-III de la figure 2 de ce pied avec le montant enfiché et verrouillé.In any case, the invention will be well understood, and its advantages and other characteristics will emerge during the following description of a nonlimiting exemplary embodiment, with reference to the appended schematic drawings in which
Figure 1 is a partial perspective view of a balcony railing equipped with these legs for fixing the uprights;
Figure 2 is an exploded perspective view of this mounting foot
Figure 3 is a vertical section on III-III of Figure 2 of this foot with the upright inserted and locked.

La figure 1 représente schématiquement un garde-corps, ou balustrade, de balcon équipé de montants verticaux 1 qui sont enfichés, bloqués et verrouillés chacun dans un pied 2 vissé dans la dalle 3. Comme on le voit plus nettement sur les figures 2 et 3, chaque pied 2 repose sur la dalle horizontale 3 par l'intermédiaire d'une embase plane 5. Cette embase est percée d'un seul trou 6, situé du côté intérieur du balcon et qui reçoit une vis de fixation 4. Figure 1 schematically shows a railing, or balustrade, balcony equipped with vertical uprights 1 which are plugged in, blocked and locked each in a foot 2 screwed into the slab 3. As can be seen more clearly in Figures 2 and 3 , each leg 2 rests on the horizontal slab 3 via a flat base 5. This base is pierced with a single hole 6, located on the inside of the balcony and which receives a fixing screw 4.

Le pied 2 est creux, et il reçoit un montant tubulaire vertical 1, de section parallélépipèdique, les dimensions respectives étant telles que le montant 1 s'enfiche étroitement dans ce pied. Au moins une des faces latérales du pied est percée de deux petits trous horizontaux taraudés 7, qui reçoivent chacun une vis-pointeau 8, ou "vis bout-cuvette". Ces deux vis-pointeaux 8 permettent d'effectuer un premier serrage pour bloquer le montant 1 en position dans le pied 2 après enfichage. The foot 2 is hollow, and it receives a vertical tubular upright 1, of rectangular section, the respective dimensions being such that the upright 1 is tightly plugged into this foot. At least one of the lateral faces of the base is pierced with two small horizontal tapped holes 7, which each receive a needle screw 8, or "cup-end screw". These two needle screws 8 allow a first tightening to block the upright 1 in position in the foot 2 after insertion.

Sur la face verticale 9, qui regarde vers l'intérieur du balcon, c'est-à-dire vers le trou 6 et la vis 4, est prévu un perçage horizontal 10, de diamètre suffisant pour laisser passer, sangs jeu appréciable, une vis auto-foreuse Il, spécialement traitée pour tenir en corrosion au brouillard salin. On the vertical face 9, which looks towards the inside of the balcony, that is to say towards the hole 6 and the screw 4, is provided a horizontal bore 10, of sufficient diameter to allow passage, significant clearance blood, a self-drilling screw II, specially treated to withstand corrosion by salt spray.

Cette vis auto-foreuse 11 est d'un modèle courant et comporte une extrémité 12 en forme de forêt, suivie d'une partie filetée 13. This self-drilling screw 11 is of a current model and has an end 12 in the form of a forest, followed by a threaded part 13.

Pour verrouiller le montant 1 après avoir serré les vis-pointeau 8, on introduit la vis 11 dans l'orifice 10 et l'on fore un trou dans le montant tubulaire 1. Puis, en continuant à visser, la partie filetée 13 vient tarauder le trou perçé. Elle s'y visse puis, en fin de vissage, elle vient serrer et verrouiller le montant 1 dans le pied 2. To lock the upright 1 after having tightened the needle screws 8, the screw 11 is introduced into the orifice 10 and a hole is drilled in the tubular upright 1. Then, while continuing to screw, the threaded part 13 comes to tap the hole drilled. It is screwed into it then, at the end of screwing, it comes to tighten and lock the upright 1 in the foot 2.

Il st à remarquer que, hormis la pose et le serrage des vis-pointeau 8, qui sont des opérations aisées, la fixation du pied 2 à l'aide de la vis 4 ainsi que la fixation du montant à l'aide de la vis 11, qui sont deux opérations difficiles, s'effectuent ici toutes deux du côté intérieur du balcon, là où l'accès est le plus aisé. It should be noted that, apart from the installation and tightening of the needle screws 8, which are easy operations, the fixing of the foot 2 using the screw 4 as well as the fixing of the upright using the screw 11, which are two difficult operations, are carried out here both on the interior side of the balcony, where the access is easiest.

L'invention n'est bien entendu pas limitée à l'exemple de réalisation qui vient d'être décrit. L'embase 5 du pied 2 peut avoir une autre forme, à deux ou trois branches recevant chacune une vis par exemple. On peut avoir une, deux, ou plus, vis-pointeau 8 sur plusieurs faces verticales du pied 2. On peut prévoir un verrouillage par deux vis auto-foreuses 11, et même plus, etc. The invention is of course not limited to the embodiment which has just been described. The base 5 of the foot 2 may have another shape, with two or three branches each receiving a screw for example. One can have one, two, or more, needle screw 8 on several vertical faces of the foot 2. One can provide a locking by two self-drilling screws 11, and even more, etc.
