Abstract

The present invention relates to a composite baluster. Composite baluster, consisting of tubular decorative elements (1) mounted on a rigid support (2), characterized in that the rigid support (2) is in one piece and in that the decorative elements (1) are fixed on the support (2) by decorative end parts (3) cooperating with an invisible means (4, 5) of subjection to the support (2). The invention is more particularly applicable in the field of manufacturing balusters.

Description

Composite baluster

  The present invention relates to the field of the industrial manufacture of ironwork pieces,

  especially for guardrails and balustrades, and has for object a composite baluster. There are currently many pieces of prefabricated ironwork, including balusters, whose constituent elements are welded or assembled by screwing. These prefabricated balusters are generally fixed on the high and low rails of said railings or railings by means of screws passing through these rails or by welding and are easy to implement. 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 of a less noble material

  such as iron These balusters provide an interesting decorative effect, but require relatively large manufacturing and mounting operations, which considerably increases their cost.

  Indeed, these known balusters require a mounting of their decorative parts on a guide sleeve and stiffening, the assembly being assembled25 by means of an axial rod, fully threaded or at least threaded at its ends, said rod cooperating with pierced and threaded end machined parts clamping said parts, generally with the interposition of a compression ring The end machined parts are further intended for fastening the balusters to the high and low rails of the balustrades

  or railing they equip. The present invention aims to overcome these disadvantages.

  It has in effect a composite baluster consisting of 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

  end decorative parts cooperating with an invisible means of attachment to the support.

  The invention will be better understood thanks to the description below, which relates to a method of

  1 is a partial view in elevation and in section of a baluster according to the invention, and FIG. 2 is a non-limiting example, given with reference to the appended diagrammatic drawing, in which: FIG. is an enlarged sectional view of

detail A of Figure 1.

  According to the invention and as shown in FIGS. 1 and 2 of the accompanying drawing, the baluster

  The site, which consists of tufted decorative elements 1 mounted on a rigid support 2, is characterized in that the rigid support 2 is in one piece and in that the decorative elements 1 are fixed on the support 2 by decorative end parts

  3 cooperating with an invisible means 4, 5 of subjugation

support 2.

  The rigid support 2 is advantageously constituted

  killed by a stretched rod, whose section is adjusted to the inner section of the tubular decorative elements

  1 and end decorative parts 3 with a sliding

  Thus, it is possible to ensure perfect assembly of elements 1, support 2 and

  parts 3 with very good stiffening of

1.

  The decorative end portions 3 may advantageously be constituted by rings resting on the elements 1 at each end of the support 2. The invisible means 4, 5 for fastening each decorative part 3 to the support 2 (FIG. ) is constituted, according to a characteristic of the invention, by a pressure screw 4 passing through a tapping of the part 3 and cooperating with a housing 5 provided on the support 2 The screw 4 is advantageously made of a material identical to that constituting the part 3 and

  cut, after tightening, flush with part 3, then the assembly is sanded and polished so as to make the fastener almost invisible.15 According to a variant embodiment of the invention,

  not shown in the annexed drawing, the invisi-

  4, 5 may also be constituted by a pin cooperating with corresponding holes of the support 2 and the decorative part 3, this pin-20 being force-fitted, riveted, glued, etc., and its ends being cut flush of part 3, then

sanded and polished.

  Decorative elements 1, as well as

  decorative elements or rings 3, end and the invisible means 4, 5 for securing the support 2 are advantageously made of a noble material, such as brass, copper, stainless steel or any other

noble metal.

  The embodiment according to the invention allows a total prefabrication of all parts of a composite baluster with extremely low tooling and labor costs while ensuring,

  after mounting, a flawless finish, the baluster ob-

  held only having to undergo the final operations of coating the ends, varnishing of the decorative elements 1, parts 3 and means 4, 5, and

  conditioning before storage and shipping.

  Thanks to the invention, it is possible to make a composite baluster usable for the production of stair railing, railing, or other, which can easily and quickly be put in place. In addition, because of the relatively simple constitution and construction, the invention permits a substantial reduction in the cost price of such a cabinet. Finally, thanks to the means 4, 5 of subjugation

  invisible, the decorative effect of the baluster according to the invention is significantly improved.

  Of course, the invention is not limited to the embodiment described and represented in the drawing

  xed Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of equivalent techniques, without leaving

  for all that the field of protection of the invention.
