Description

"Connection conduit element.

  in particular of a sanitary installation "The present invention relates to a connecting duct element, in particular of a sanitary installation, adapted to extend through a passage of a wall or a partition of a

  dwelling, in particular of a thin interior partition.

  According to an object of the invention, the connecting duct element comprises, in front of a peripheral shoulder, a threaded part, a threaded washer adapted to be screwed onto said threaded part and having means for receiving a key. drive so that, said part being engaged through said passage, said wall can be taken between said shoulder and said washer screwed onto said threaded part, as well as means for coupling it to other conduit elements of on either side of said

wall.

  According to another object of the invention, the connecting duct element comprises, in front of said shoulder, at least one projecting part capable of engaging in a local recess of the wall

  carried out in the vicinity of said passage.

  According to the invention, two diametrically projecting parts

  opposite are preferably provided.

  According to the invention, said projecting part is preferably carried by said shoulder and extends forwards towards the side of said

threaded part.

  According to the invention, said means for receiving a drive key preferably comprise two diametrically opposite holes. According to another object of the invention, the rear part of the connection duct element, situated opposite its threaded front part with respect to said shoulder, comprises coupling means adapted to cooperate with means of coupling

  complementary to a crossbar.

  According to the invention, said coupling means may advantageously comprise a projecting coupling part 1 having two opposite parallel faces and said transverse bar is preferably a U-shaped section profile between the branches of which said coupling part can be engaged in a position such that its opposite parallel faces are in abutment against these branches. According to the invention, said projecting coupling part can have a tapped hole adapted to receive a screw for fixing it.

  in one place along said profile.

  According to a variant of the invention, its aforesaid rear part is bent and its aforementioned projecting coupling part is formed towards

  the rear in line with its threaded front part.

  The present invention will be better understood from the study of a connecting duct element of a sanitary installation of a dwelling, described by way of nonlimiting example and illustrated by the drawing in which: - Figure 1 shows a side view of a connection duct element according to the invention, mounted on a partition shown in section; - Figure 2 shows a front view of the conduit element of Figure 1; - Figure 3 shows a top view of two duct elements according to the invention, mounted on a partition and connected by a crossbar; - And Figure 4 shows a rear view of the mounting of the

figure 3.

  The duct element 1 shown in the figures is constituted by an elbow of circular section which comprises a horizontal branch

  2 and a vertical branch 3 which extends downwards.

  The horizontal branch 2 comprises a threaded end front part 4 which is formed in front of a peripheral annular shoulder 5 which carries, on its face turned towards this threaded front part 4, two projecting parts or positioning bosses 6 and 7

diametrically opposite.

  The duct element 1 also comprises a flat washer 8 1 which has an internal axial rim 9 and the passage of which has a thread 10 capable of coupling on the threaded part 4. This washer 8 also has two through holes 11 and 12

diametrically opposite.

  In its bent part located behind its shoulder 5, the conduit element 1 comprises a projecting part 13 which extends backwards in alignment with its horizontal branch 2. This projecting part 13 comprises two faces opposite and parallel 14 and 15 which extend perpendicular to the vertical branch 3 and an end face 16 in which is formed a threaded hole 17 which extends

along the axis of branch 2.

  To mount the duct element 1 on a vertical partition 18, a horizontal cylindrical passage 19 with a diameter slightly greater than the diameter of the threaded portion 4 is produced in the latter, and two diametrically opposite local recesses 20 and 21 of dimensions

  slightly higher than the positioning bosses 6 and 7.

  Then, the threaded part 4 of the duct element 1 is engaged through the passage 19 and the positioning bosses 6 and 7 in the recesses 20 and 21, until the shoulder 5 is in contact.

  with the corresponding face of the partition 18.

  Then, by the other side of the partition 18, the washer is screwed onto the threaded part so that its rim 9 engages in the orifice 19 of the partition, the partition element being kept in rotation by means of the

positioning bosses 6 and 7.

  To strongly take the partition 18 between the shoulder 5 and the washer 8, for example using a tool or wrench 22 consisting of a plate which comprises two branches 23 and 24 whose ends are engaged in the two through holes 11 and 12 of the washer 8 and we

turn this tool.

  After which, the end of the branch 4 is mounted with another conduit element constituted in particular by a tap, for example by screwing it into the branch 2, and the end of the branch 3 is connected to another conduit for connection 26, for example using a nut 27

or by welding.

  1 To facilitate the mounting of two duct elements 1 and the on the partition 18, it is advantageous to use a mounting crossbar 28 constituted by a U-shaped section profile whose spacing between the branches 29 and 30 corresponds to the thickness between the sides 14 and 15 of the boss 13 of the element

  conduit 1 and several orifices 31 provided through its core 32.

  Having chosen a particular spacing between the two duct elements 1 and the one to be mounted, their bosses 13 are engaged between the branches 29 and 30 of the profile 28 by arranging their branches 2 perpendicular to the length of the profile 28 and they are fixed by means of screw 33, through selected holes 31 and in the tapped holes 17 of their bosses 13, the conduit elements 1 and the being so

  maintained parallel and at a determined spacing.

  Then, two through passages 19 are made in the partition 19 at the chosen spacing of the duct elements 1 and the to be mounted, as well

  as the recesses 20 and 21 as described previously.

  The two elements 1 and 1 are engaged at the same time in the two passages 19 and their washers 8 are mounted as described above. Then, connect the ends of the conduit elements 1 and the to

  other conduits as described above.

  The present invention is not limited to the example described above. Variants of realization are possible without leaving the framework

of the appended claims.
