Abstract

The waste pipe system for double sinks comprises two drain units (1) which can be mounted in the sinks and have a long (2) and a short (3) waste pipe molded in one piece with them. The longer pipes are of smaller diameter than the shorter ones and fit into them when the system is assembled.

Description

-1- SINK DRAIN

  The present invention relates to an exhaust assembly, more particularly adapted to the equipment of a sink.

  It is known on the market evacuation sets that equip the sinks, they are one or two bins. These evacuations are composed of grids, tubings connecting the two tanks and a siphon organ. Fixing processes can be varied, stainless steel screws in the center of the grid, diametrically opposite screws or bung (plastic or brass) to screw.

  The two bins are interconnected by tubing (plastic or metal, rigid or flexible), the most common case on the market being rigid plastic. The outlets of the bins can be at the same level, or shifted to different height (possibly with the presence of a vacuum sauce between the two bins for example). Connections are provided on the tubing or on the drain for the evacuation of the overflow sink and possibly for the evacuation washing machine (dishes, linen). Case rarer, the presence of a third tank in the center of the sink. It is also known products on the market (such as FR 2835905 of Valentin SA) resembling the invention, but not having the main features of the invention.

  The inventor of the present solution has devised a system and a principle intended to solve the following problems that he has been confronted with, namely: The present emptying assemblies are composed of numerous parts to be assembled, which involve several operations and often several references, the number of parts requires many manufacturing molds, dump sets appeared on the market (bung and integrated tubing) with a limited number of parts, but the breakage of one of the constituent parts (bonde) implies often the complete redemption of the set of dump, Competition is such that products have more and more difficult to differentiate visually from each other (counterfeits).

  The author of this new geometry has therefore reflected on a solution that can meet the majority of the problems encountered. The solution deduced and proposed object -2- of the invention, therefore required reflection time, in order to solve these problems. First and foremost, it is notable that it is the goal of simplifying the emptying system by limiting component parts that is the main axis of reflection.

  The inventor has therefore imagined a geometry resulting in a room retaining the majority of the benefits while limiting the constraints previously expressed. The solution deduced from the work of reflection was thus the following: design and realization of a set of bung, whose assembly of two identical copies in manufacturing from the molding constitutes a set of dump for a sink two bins. The thoughtful solution allows: A decrease of the constituent parts, A single mold for the body of bung and connection evacuation, The supply for a sink with a single tank is also one of the constituent parts for the sink with two bins (easier for after-sales for example), Its visual identity is such that it is an undeniable mark of the original design of this model (the counterfeit would be obvious). This design is therefore intended to be protected by the present patent application as well as the copyright of invention and copyright concerning the intuitive and reasoned approach that leads to the proposed solution.

  The invention proposes a geometry of evacuation pipe allowing, with a single model resulting from manufacture (exit of the mold), to satisfy the emptying of a sink double bowl, adjustment of the connection distance included, with machine tap to wash and overflow, and possibly connecting a third tank. To satisfy a sink with two staggered bins (about 4 cm), it is possible to deliver a complementary seal in order to make up the difference in height. One body allows the emptying of a tray. To illustrate mainly our purpose, we present in board 3/4 - Fig.6 the object of the invention mounted (not restrictive), with connection by nut of the 2 evacuation connections (nuts not represented). In its main characteristic, the bung body (1) comprises two horizontal evacuation pipes (or conduits) (2) and (3), arranged on the same plane and of different diameters, connected at their base to the body (1). ) of bonde, so that -3- put one against the other by a rotation on the same plane, the two pipes (2) and (3) can slide respectively one in the other without excessive play. In the example shown in fig.6, a space (19) between the two ducts (2) and (3) connected allows the passage of the nuts (not shown) so as to perform a correct tightening, without them get stuck each other. Similarly, within the scope of the invention a body (1) bung whose two tubes (2) and (3), are positioned on the same axis and same plane, but diametrically opposed (Fig.7). Another geometry still possible (FIG. 8) is to have the two lines (2) and (3) arranged at right angle on the same plane at 90 to form a right angle between the respective axes of the male (2) and female tube. (3). The bung body (1) is secured to the sink by tightening a bung (metal for example) or by a central screw immersed in a tapping (9) integral with the bung body (1), or through the body (1) plug to tighten an insert nut. Just as much, another geometry allows the attachment of the bung (not shown) with two opposite screws in spaces (18) threaded or smooth, the fixing screw (not shown) being self-drilling in the case of a passage ( 18) not tapped. Figures 1, 2 and 3 show an embodiment of a body (1) bung, Figures 1 and 2 in top view, Figure 3 in profile view.

  In Figure 1, the body (1) bung is shown in plan view, comprising two outlet pipes / connection (2) and (3), with the openings / section (4) evacuations. The female conduit (3) has a thread (5), which serves to connect / tighten a seal (conical or otherwise) to seal (traditional known function not shown). An overflow (8) is present on the bung body (1). This overflow (8) serves to evacuate the excess liquid from the upper tray to the body (1) of bung. Fixing the bung grid (plastic or stainless, not shown) is possible by a central screw (not shown) inserted into the passage / tapping (9). The tapping or single hole (9) is supported by branches or ribs (11) integral with the body (1). The seal between the bung body (1) and the underside of the sink pan (not shown) is applied to a ribbed bearing surface (10) which serves to support the gasket (not shown). In FIG. 2, the bung body (1) has two connections (8): overflow and washing machine. A passage (12) downwards to evacuate the wastewater, by connecting on the net (13) either directly a siphon or a horizontal angled discharge pipe to which will be connected an offset siphon. The tubes (2) and (3) open into the space (14) inside the body (1) bung by the sections (6) and (7). The tubes or conduits (2) and (3) are integral with the bung body (1) by their base, the pipe (3) having a thread (5) and the pipe (2) being smooth. The lengths of the tubes (2) and (3) of the drainage links may be of different lengths and long enough to allow connections on sink two bins. Indeed, in order to satisfy the different spacing configurations (spacing between the two sink holes), it is possible to cut the smooth tube (2) so that, nested one (2) in the other (3), the gap between the two bodies (1) of bung is as small as possible (see Figure 6) and adapted to the center distance of the sink drain holes. In FIG. 3, the bung body (1) is shown in profile, and gives an embodiment of the bung body (1). A possible configuration is to have the outlet (12) plugged by a cover (15), in this case the net (13) having function only if the cover (15) is removed, a pipe then being connected on the clamping output on the thread (13). Figures 4 and 5 show another embodiment of a bung body (1), Figure 4 in profile view, Figure 5 in top view. In Figure 4, the body (1) of the bung shown in profile comprises a connection (8) overflow or washing machine. The tube (3) has no thread, the technique used in this example (see Figure 5) for the connection being the rolling o-ring (17) disposed on the connecting tube of smaller diameter (2). The insertion of the tube (2) into the tube (3) when another body (1) of bung is presented in front allows the seal (17) to roll and get caught between the outer wall of the tube (2) and the inner wall of the tube (3). The outlet (12) can be plugged during manufacture by a cover (15). In fact, it is up to the customer, during assembly, to choose the location of the exhaust connection 30 (in the case of two bins, left or right). The opening is achieved by removing the lid (15). This solution avoids the provision of a solid plug and a seal in the case where the opening is already made (during manufacture). In FIG. 5, the bung body (1) is shown in plan view, comprising two outlet / connection pipes (2) and (3), with their openings (4) on the outside. These two pipes also open into the space (14) through the openings (6) and (7). An overflow (8) is present on the body (1). Fixing the stainless steel bung (not shown) is possible by two screws (not shown) each fitting into the passages (18). The threads or single holes (18) are integral with the body (1) of bung. In the case of the simple hole (18), it is the self-drilling screw that leads to the tightening; this solution avoids having complex equipment necessary to release a tapping. The seal between the bung body (1) and the underside of the sink pan (not shown) is applied to a flat surface (16). A thicker seal may be provided to compensate for the difference in level when the two bins are staggered. A passage (12) allows the effluent to be discharged through the bottom of the body (1) from the bung, by connecting directly to the net (13) a siphon or a horizontal bent evacuation pipe to which will be connected downstream. offset a siphon (for example placed along the wall). The tubes (2) and (3) are integral with the body (1) bung. The lengths of the tubes (2) and (3) of discharge connections can be in this case of equal lengths, simply cut to adjust the distance between the two bungs. In fig. 6 is presented a set of assembled dump. It is clear that the two bodies (1) of bungs arranged opposite each other fit perfectly. Nuts and seals (not shown in the example) seal the connections (2) and (3) spaced apart from the space (19). Two outlets (8) too full are present. We note that the flow from one tank to another (between the two tanks) passes simultaneously through the two connection pipes, which makes it possible to limit the diameters of the tubes (2) and (3) when the outlet of the Effluent is through the outlet (12). In the case where the two openings (12) are open original, one of them receives either a tubing or siphon. The other opening must be plugged with a solid screw cap with seal. This solution offers a possibility of cleaning from below the bung.

  In fig. 7 another geometry is possible, with the body (1) of bung in top view, comprising two output pipes / connection (2) and (3). These two pipes (2) and (3) are diametrically opposed. The face-to-face placement of two identical bung bodies (1) thus has an evacuation assembly, the evacuation of the effluents may be horizontal, or by the tube (3) with thread (5). or by the smooth tube (2) in the case where the outlet (12) is closed (or non-existent in the mold by the presence of the lid (15) for example). In this case, the two bodies (1) of bung are in line, the evacuation of the one passing by the other. The evacuation can therefore be done for example by the tubing (3) or the tubing (2). The fixation of the body (1) bung can then be achieved by a central screw fixed in the housing (9) without ribs (11) - not shown in drawing - this housing (9) being a simple vertical tube from the bottom (15). ) of the body (1) of bung.

  In fig. 8, another variant is a body (1) of bung with the two tubes (2) and (3) arranged at the square. In the same way, the arrangement of two identical bung bodies (1) allows the constitution of an evacuation assembly. We can note that this arrangement at right angle can be a characterizing function of the invention. In the case of the geometries shown in FIG. 7 and 8, it is possible to choose the horizontal outlet of the effluent evacuations (if the section (12) is not open) by connection to the threaded tube (3) of a tubing or a siphon, or by connection on the smooth tube (2) of a siphon in line or piping with connection by push-fit type seal, or still to stick. It should be noted in these two models (fig.7, fig.8) that the pipes (2) and (3) can be of large diameters (for example about 40 mm), because of the need for significant evacuation of one tray to the other (serial output). It should be noted that throughout the text, the overflow outlet is not considered as an evacuation pipe, a term reserved for pipes allowing either the evacuation of effluent directly from the body (1), or the pipe (s) providing (s) the drain connection between the two bodies (1) of bung mounted on a double sink. It is notable to consider the term body (1) of identical bung as the fact of being able to achieve a double-bin emptying by assembling two bodies from the same mold. The mere fact of the presence or not of the lid (15) does not allow to circumvent the identical term, it also referring to the visual identity of the room (likewise, a simple difference in weight or color do not question the identical term).
