Description

  

  <B> Profiled bar </B> The present invention relates to a profiled bar characterized in that it has two longitudinal planes of symmetry perpendicular to each other and that it has at least one transverse notch intended to serve as a housing and removably retaining a bar of the same profile.



  The appended drawing represents, by way of example, three embodiments of the bar which is the subject of the invention.



  Fig. 1 is a side view of the first form.



  Fig. 2 is a sectional view along II-II of FIG. 1.



  Fig. 3 is a side view of the second form.



  Fig. 4 is a sectional view along IV-IV of FIG. 3.



  Fig. 5 is a side view of the third form.



  Fig. 6 is a sectional view along VI-VI of FIG. 5.



  The profiled metal bar 1 shown in FIGS. 1 and 2 has a cross section in the shape of an X, the branches 2 and 3 of the latter having axes 4 and 13, forming an angle of 90 "between them. The bar 1 has two longitudinal planes of symmetry per pendicular between them , represented by their traces 5 and 6.



  The bar 1 comprises two sets 7 of transverse notches; each set 7 has a pair 9 of notches 11 made in branch 2, and a pair 10 of notches 12 made in branch 3; for each set, the notches 11 of one pair are opposite the notches 12 of the other pair. In each assembly 7 can be engaged a bar 1, the latter being movable longitudinally and being able to be held captive.



  Provision is made for a bar 1 having a notch made in each branch 2 and 3, these two notches being of the same shape and facing each other, can also serve as a housing for another bar 1.



  Bars similar to the bar 1 shown can be used to easily produce the frame of a piece of furniture that can be dismantled, in particular a shelf, and this without it being necessary to use assembly means such as screws, bolts, che cities.



  The profiled metal bar 14 shown in FIGS. 3 and 4 has a cross section in the form of a double dovetail; the bar 14 has two longitudinal planes of symmetry perpendicular to each other represented by their traces. 15 and 16 and. consists of two parts 17 and 18; each of these has a notch 19 in which a bar 14 can be engaged, the latter being movable longitudinally while being trapped.



  It is planned to produce a bar that only has a notch 19.



  The profiled metal bar 20 shown in FIGS. 5 and 6 has a cross section in the general shape of a four-pointed star 21, 22, 23 and 24; it has two longitudinal planes of symmetry per pendicular between them represented by their traces 25 and 26; the branches 21 and 23 have a common axis 27 perpendicular to the axis 28 common to the two branches 22 and 24.



  The bar 20 comprises on the one hand a pair of opposite notches 29 formed respectively in the branches 21 and 22 serving as a housing for a bar 20, and, on the other hand, a pair of facing notches 30 respectively provided. in branches 23 and 24.



  The bar 20 could only have a pair of facing notches.



  Metal bars similar to the bars 14 respectively 20 are also capable of being used to easily produce removable frames or frames.

 

Claims (1)

CLAIM Profiled bar, characterized by <B> the </B> that it has two longitudinal planes of symmetry perpendicular to each other and that it has at least one transverse notch intended to serve as a housing and to removably retain a bar of the same profile. SUB-CLAIMS 1. Bar according to claim, characterized in that it has several dirty transverse notches. 2. Bar according to claim and sub-claim 1, characterized in that it has an X-shaped cross section. 3. Bar according to claim and subclaims 1 and 2, characterized in that the axes of the branches of the X form an angle of 900 with each other. 4. Bar according to claim and subclaims 1, 2 and 3, characterized in that the branches of the X have at least one pair of notches, which are facing each other. 5. Bar according to claim and subclaims 1 to 3, characterized in that the branches of the X have at least one set of two pairs of notches, the notches of one pair being opposite those of the 'another pair so as to allow the insertion of the same bar. 6.
