Description

La présente invention concerne le domaine de la fabrication industrielle de pièces de ferronnerie, notamment pour garde-corps et de balustrades, et a pour objet un balustre composite.The present invention relates to the field of industrial manufacture of ironwork parts, in particular for railings and balustrades, and relates to a composite baluster.

Il existe actuellement de nombreuses pièces de ferronnerie préfabriquées, notamment des balustres, dont les éléments constitutifs sont soudés ou assemblés par vissage.There are currently many prefabricated pieces of ironwork, in particular balusters, the constituent elements of which are welded or assembled by screwing.

Ces balustres préfabriqués sont généralement fixés sur les lisses haute et basse desdits garde-corps ou balustrades au moyen de vis traversant ces lisses ou par soudage et sont de mise en oeuvre facile.These prefabricated balusters are generally fixed to the top and bottom rails of said railings or balustrades by means of screws passing through these rails or by welding and are easy to implement.

Il existe également des balustres composites, dans lesquels les pièces décoratives sont réalisées en un métal noble,'généralement relativement fragile, et montées sur un support rigide en un matériau moins noble tel que le fer. Ces balustres permettent l'obtention d'un effet décoratif intéressant, mais nécessitent des opérations de fabrication et de montage relativement importantes, ce qui renchérit considérablement leur prix de revient.There are also composite balusters, in which the decorative pieces are made of a noble metal, 'generally relatively fragile, and mounted on a rigid support in a less noble material such as iron. These balusters allow an interesting decorative effect to be obtained, but require relatively large manufacturing and mounting operations, which considerably increases their cost price.

En effet, ces balustres connus nécessitent un montage de leurs parties décoratives sur un manchon de guidage et de rigidification, l'ensemble étant assemblé au moyen d'une tige axiale, entièrement filetée ou au moins filetée à ses extrémités, ladite tige coopérant avec des pièces usinées d'extrémité percées et taraudées serrant lesdites parties, généralement avec interposition d'une bague de compression. Les pièces usinées d'extrémité sont destinées, en outre, à la fixation des balustres sur les lisses haute et basse des balustrades ou garde-corps qu'ils équipent.In fact, these known balusters require mounting their decorative parts on a guide and stiffening sleeve, the assembly being assembled by means of an axial rod, fully threaded or at least threaded at its ends, said rod cooperating with end machined parts drilled and tapped tightening said parts, generally with the interposition of a compression ring. The machined end pieces are also intended for fixing the balusters on the top and bottom rails of the balustrades or railings they equip.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un balustre composite, constitué par des éléments décoratifs tubulaires montés sur un support rigide, caractérisé en ce que le support rigide est en une seule pièce et en ce que les éléments décoratifs sont fixés sur le support par des parties décoratives d'extrémité coopérant avec un moyen invisible d'assujetissement au support.It has, in fact, for its object a composite baluster, constituted by tubular decorative elements mounted on a rigid support, characterized in that the rigid support is in one piece and in that the decorative elements are fixed on the support by decorative end parts cooperating with an invisible means of securing to the support.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel :

  • la figure 1 est une vue partielle en élévation et en coupe d'un balustre conforme à l'invention, et
  • la figure 2 est une vue agrandie en coupe du détail A de la figure 1.
