Abstract

Device allowing the fixing of hollow beams without the fixing elements being visible.

Description

Hollow beam fastening device for decorative use Techniques

current premises construction

  for residential use favor ceilings with flat surfaces.

  If, for decorative reasons, we want to make beamed ceilings or exposed joists in wood, or in substitute products, it is advantageous to use hollow products made from assembled wooden elements

  by gluing or from molded synthetic material.

  These products are generally in the form of a U which is fixed with conventional means (nails, screws, dowels)

under flat ceilings.

  This fixing work is delicate and inconvenient

  because it requires drilling, screwing or nailing

  ceilings, very often fragile by nature.

  On the other hand, these conventional means leave traces on the apparent surfaces of these hollow elements and

  require capping and touch-up work.

  The object of the present invention is to remedy the above-mentioned fixing drawbacks, the essential idea being to use the space available inside these hollow elements in order to adapt a spring clip made up of two

  parts One of the parts of the device is prefixed to the plate

  bottom, the other inside the hollow beam.

  This provision allows, after fixing the provision

  sitive, to set up the elements by simple pressure.

  The invention will be better understood from the description

  below, given by way of nonlimiting example, and explained

with reference to the accompanying drawing.

  2 - The drawing is a sectional and elevation view of a hollow beam (1) fixed to the ceiling (2) using the device

(3, 4, 5, 6) according to the invention.

  This device according to drawing is composed of a male part (5, 6) fixed to the ceiling (2) generally in plaster, to

  using screws, the plate (6) of rectangular shape comprises

  both holes for fixing them The spout (5) of the same width as the plate (6) to which it is fixed by

  welding and obtained by folding, has at its end oppo-

  attached to the plate (6) a conical part (5 a) ending in

  rounded facilitating the introduction of the female part (3,4).

  The female part is itself made up of a

  plate (3) preferably identical to plate (6).

  The element (4) is fixed by welding in the same way as the element (5) to the plate (6) and its width is identical

  to that of the plate (3) The element (4) in steel, as of gar-

  their whole illustrated device, has a rectangular shape

  laire when it is not engaged in the male part (5).

  It forms a spring and moves away when you come to exert pressure on the beam (1) that you want to fix. The lips (4 a) come to be housed in the notches (5 b) whose position can be studied in such a way that the device put in place can exert constant pressure on the

  edges of the beam (1) bearing on the ceiling (2).

  The elements (5, 6) are fixed to the ceiling, their posi-

  tion being previously traced, using special screws when the ceiling is formed of plastered plates, this work

  being easy thanks to the absence of hollow beams.

  These are fitted when the elements (4, 5) are

  fixed inside the beams at a well defined interval.

  This description is not limiting, the arrangement

  tif which can be made of plastic elements obtained by molding, as well as the realizable beams in material

molded synthetic.

  It is also evident that this device can

  apply to the fixing of vertical hollow beams or posts

  caux, because in this case it has the same advantages.

  3 - The device which is the subject of this patent facilitates the installation of beams or any hollow elements for use

  decorative without any visible fastening elements, and this installation can be carried out by a non-professional person, simply gifted for DIY.

Claims (6)

R E V E N D I C A T I O N S -   1 device for fixing decorative elements in the form of hollow beams or joists (1) having an open side which is applied against a flat surface (2), characterized in that this consists of two parts, a male part (5, 6) and a female part (3, 4), a part coming   be fixed before installing the beam using standard means   sics such as nails, screws, dowels, on the ceiling, the other part on the inside of the beam (1) opposite the flat surface (2), the two parts fitting together ensuring fixation.   2 Device according to claim 1 characterized in that the male part (5, 6) consists of a plate   (6) rectangular in shape with holes for the passage   age of nails, screws or dowels, integral with the element (5), of hollow shape and substantially rectangular, perpendicular   to it and of substantially equal width.   3 Device according to claim 2 characterized in that the male part (5) comprises at its end opposite the plate (6) a conical part (5 a> allowing to separate   the lips (4 a) of the female part (4) during fitting.   4 Device according to claims 2 and 3 characters-   laughed in that the male part (5) has two recesses   (5 b) symmetrical with each other, now prison-   nières the lips (4 a) of the female part (4) constituted of elastic material.   Device according to claims 2 to 4 characters   laughed in that the elastic element (4) is integral with a   plate (3) identical to plate (6).   6 Device according to claim 5 characterized in that the female element (4) is of rectangular shape and   of thickness substantially equal to the male element (5).
