DETAILED DESCRIPTION

The concept of the invention is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the concept of the invention are shown. Similar numbers refer to similar items on all drawings. However, this concept of the invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Instead, these embodiments are provided so that this description is complete, and communicate the scope of the concept of the invention to those skilled in the art. The scope of the invention is therefore defined by the appended claims.

Reference throughout the description to "an embodiment" means that a particular feature, structure, or feature described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in one embodiment" at various locations throughout the specification does not necessarily refer to the same embodiment. In addition, the particular features, structures, or features may be combined in any suitable manner in one or more embodiments.

With reference to the figures, the invention relates to a connecting piece 1, for connecting a down pipe 3 to a discharge pipe 2. Said pipe is still called a downflow pipe. Advantageously, the part 1 has a height less than its width.

According to one embodiment, said part is made of Acrylonitrile Styrene Acrylate.

According to one embodiment, the gutter down pipe 3 is of non-circular section. In particular, in the example illustrated in FIG. 3, the gutter downcomer pipe 3 is of rectangular section.

In a variant, as detailed below, in the example illustrated in FIG. 4, the inner peripheral wall 11 has a generally circular shape adapted to receive a gutter down pipe 3 of circular section.

In the example illustrated in FIG. 3, the evacuation pipe 2 is of circular section. Alternatively, it may be provided that the discharge pipe 2 is of non-circular section, provided that the outer peripheral face 12 of the part 1 is adapted to be engaged in the evacuation pipe, while coming to cap with its flange 13 the periphery of the end face of the evacuation pipe 2.

Usually, the discharge pipe 2 is taken from the ground and has a mouth protruding from the ground. As explained below, if the pipe 2 has not previously been brought to the surface of the floor, it is proceeded, with a view to the use of said connecting piece 1, to the cutting of this projecting part to bring the pipe 2 out of the ground.

In the example illustrated in Figures 1 to 3, said part 1 comprises an outer peripheral wall 12 of circular section adapted to be engaged in said discharge pipe 2.

Said part 1 also comprises an inner peripheral wall 11 of non-circular section. In the example illustrated in Figures 1 to 3, the section of the inner peripheral wall 11 is of generally rectangular shape, the corners are preferably cutaway. Said inner peripheral wall 11 delimits a through passage 110 for receiving the gutter down pipe 3.

In the example illustrated in FIGS. 1 to 3, said cut faces located at the corners are inclined at an order of 45 with the adjacent dimensions of the corresponding rectangle.

The shape of the inner peripheral wall is adapted to receive the section of the gutter downcomer. The section of the inner peripheral wall is of course of greater surface dimension than that of the section of the gutter downcomer. Similarly, the section of the outer peripheral wall is of smaller surface area than the section of the discharge pipe.

Advantageously, one or more clearances of material are formed between the inner peripheral wall and the outer peripheral wall to reduce the weight and cost of the connection.

Said outer peripheral wall 12 is externally provided with a flange or flange 13 forming a stop which makes it possible to limit the penetration of said piece 1 into the evacuation duct 2. The axis of the through passage 110, which corresponds to the central axis of the section of the inner peripheral wall 11, is substantially coaxial with the axis of the outer peripheral wall 12, axis around which the outer peripheral wall 12 develops.

The inner peripheral wall 11 and the outer peripheral wall 12 have substantially the same height. The height dimension is taken along the axis of the through passage. The face defined by the free end periphery of the outer peripheral wall and the face defined by the free end periphery of the inner peripheral wall are substantially coplanar.

Said part has a wall 14, called the upper wall, which connects said inner and outer peripheral walls 11 and 12 extending perpendicularly to said inner and outer peripheral walls 11 and 12.

Said wing 13 extends parallel and in the extension of said upper wall 14 of the part 1. Said upper wall 14 forms with said flange 13 a plate whose outer peripheral edge defined by the flange 13 projects from the outer peripheral wall 12 The thickness of the wing 13, taken in a direction parallel to the axis of the through passage 110, is between 1 and 8 millimeters. The total thickness of the part, taken in a direction parallel to the axis of the through passage 110, is preferably between 10 and 60 millimeters.

Said wall 14 of the piece 1 rests on the upper end periphery of the discharge pipe 2. When the discharge pipe 2 is cut off or is configured so that this upper end periphery is flush with the ground, said upper wall 14 of the part then extends just above the ground. The thickness of the flange 13 and said upper wall 14 being small, for example of the order of 1 to 8 millimeters, it allows tiling all around the gutter down pipe 3, in particular in the case where said ground is a terrace.

The width of the wing 13, taken in a direction orthogonal to the axis of the through passage, may be between 2 millimeters and 6 millimeters.

The inner peripheral wall 11 defines a body intended to receive the gutter descent pipe 3 of similar shape section but of slightly smaller surface dimension, said body guiding the insertion of the descent pipe 3 through the part 1 to allow fluidically connecting the gutter downcomer 3 and the evacuation pipe 2.

According to the embodiment illustrated in FIG. 4, the connecting piece 1 comprises a clearance 15 formed in the inner peripheral wall 11 which allows a better engagement of the downcomer in the connection piece. Indeed, a gutter down pipe is usually shaped by folding so that, for a section of circular cross section, a projection appears on its outer peripheral face. The clearance 15 allows the passage of said projection.

The part 1 as described above makes it possible to connect a gutter down pipe 3 to a discharge pipe 2 in the following manner. If necessary, the operator cuts the portion of the evacuation pipe 2 which extends projecting from the ground. The operator proceeds to engage the part 1 by its outer peripheral wall 12 in said discharge pipe 2 until the wing 13 abuts against the end face of said evacuation pipe 2 which is flush with the ground. Then the operator engages the lower end portion of the gutter down pipe 3 in the through passage 110 of the part 1. The invention is not limited to the embodiments illustrated in the drawings. Accordingly, it should be understood that when the features mentioned in the appended claims are followed by reference signs, these signs are included solely for the purpose of improving the intelligibility of the claims and are in no way limiting to the scope of the claims. claims.

Moreover, the term "including" does not exclude other elements or steps. In addition, features or steps that have been described with reference to one of the embodiments set forth above may also be used in combination with other features or steps of other embodiments set forth above.
