Definitions

• the present invention consists in a perrectionnemem: ae the invention, by the same inventor, a stitching connection with mechanical clamping for the so-called square-shaped stitching orifices made through the wall of a sewerage collection pipe, rain water or other effluents, which gave rise to the patent FR 0407037.
• the stitching connection object of the present invention, consists of an anchor introduced into the manifold pipe through a rectangular orifice of stitching and a saddle support and connection attached to the anchor.
• the anchoring piece of the stitching connection object of the present invention, is not, unlike that described in patent FR 0407037 (lines 27 to 31 of the description), of substantially parallel shape to the inner wall of the collector.
• the deformable anchoring piece has an initial shape which is the projection of a rectangle, at optionally rounded or truncated corners, on a cylinder whose outer diameter is substantially greater than the diameter. inside the collector.
• the deformable anchor piece of the stitching connection object of the present invention, has a flexibility that allows it, after anchoring the saddle support and connection and when clamping it against the outer wall of the collector, to deform, while pressing against the inner wall of the collector, so that its initial radius of curvature decreases to become substantially equal to the inner radius of the collector.
• the said stitching connection with a deformable anchoring part is composed according to a main embodiment, of a deformable piece of anchor (2), provided with two anchoring elements and of only two (5) and two seals (9) and (10), a s "support and branch (4), said saddle support and connection having a branch socket provided with s seal (12).
• the deformable anchor piece (2) is intended to be placed inside a cylindrical collector (1), the rectangular opening (3) which has been made in the collector pc, for example to the The dimensions of the anchoring piece are such that, before deformation, it can be introduced through the rectangular opening (3) and after its deformation, all its perimeter is supported on the wall. inside the collector which surrounds the rectangular opening (3).
• the two anchorage and clamping elements (5) are located on the medial generator. the deformable anchoring piece, on its convex face.
• there are two screw holders (5) which are intended to receive the screws (6) of two rings.
• the ser. nuts on the bolt bolts have a double effect: one by 'brings the deformable anchor closer, by reducing its radii curvature, of the inner wall of the manifold (1) and ensuring that, if the tightness of the clamping is obtained at the middle generator of the anchor, it will be then form and that of the inner wall of the collector, and then, at any point of its contact with the collector inner wall, and secondly, it anchors the saddle support and connection (4) to the collector (1).
• the heads of the screws (6) are embedded in the mass of the deformable anchoring piece and in this case, the deformable anchoring piece does not comprise a screw head support.
• the deformable anchoring pi comprises, instead of supports head supports, threads which do not pass through it, said threads and fastenings of the anchor piece, for example by overmolding, being intended to receive studs or screws for fixing saddle and support.
• clamping devices such as, by way of non-limiting examples, devices intended to receive existing clamping or lever clamping systems provided with cams, or alternatively simple butif: passing through the wall of the anchor and intended to receive bolts but said bolts requiring, in this case, the i in place of specific seals so that the étanch * is ensured.
• the deformable anchor comprises a central stitching orifice (14) and two seals (9) (10).
• the seal (9) is intended to ensure the seal between the inner wall of the collector (1) and the convex face of the deformable anchoring pin, once the latter has been defo by the tightening of the bolts or studs or fixatic screw
• the seal (10) is intended to seal between the central circular ori (14) of the deformable anchor part and saddle support and connection (4).
• the seals (9) and (10) are interconnected by a sheet, of suitable shape, of the elastomer which comp and thus forming a single piece, so as to facilitate manufacture and their implementation on the anc piece seal (10), not connected to the seal (9), is fixed on the end piece (16) the saddle support and connection
• the saddle support and connection (4) is intended to be put in place to handle covering the rectangular opening (3) and to anchor itself to the deformable anchoring point, and consequently to the collector, by means of anchoring and clamping elements that said deformable anchor piece comprises.
• saddle support and connection is provided with two orifices (11) allow the passage of screws or studs.
• it comprises two clamping stops (which limit the clamping force of the nuts ( 8) on the screws (6) again on the studs.
• the saddle support and connection finally has, on the side is based on the collector (1), lateral stops (15) qi; relying on the longitudinal edges of the rectangular opening (3), prevent any movement by rotation sui collector.
• the longitudinal movement of the tapping connection limited, meanwhile, by the anchoring and clamping elements of the deformable anchor and the bolts, screws or gou that are anchored.
• FIG. 1 shows the collector (1) in which the rectangular opening (3) has been made.
• FIG. 2 shows an example of a deformable part where the anchoring and serging elements (5) are screw head supports for bolts. The said suppi (5) are shown before the introduction of the screws (6) in the upper drawings and after the introduction of the screws (6) in the bottom drawing.
• FIG. 3 represents an example of a saddle with and of connection (4) seen from two different angles. The figure represents a section along AA 1 of the stitching connection mounted collector (1), before and after the deformation of the deformable anc piece.
• FIG. 5 shows a perspective view of a stitching connection with a deformable anchoring piece once it has been installed on the collector (1).
