Definitions

  • the field of the present invention is that of the sealed connection for overflow pipes of sanitary appliances such as sinks, sinks, baths, etc ..., and in particular for bath bungs.
  • the overflow devices of a sink, sink, or bath are made by means of a flexible pipe, consisting of successive corrugations, which enters the drain intended to recover the water to be discharged, and the tightness with the bung is ensured by a set consisting of a bearing surface on the bung, a conical seal surrounding the pipe which is supported on this face of the bung, a sliding nut on the pipe and a thread on the bung intended to receive the nut in question.
  • the conical seal is compressed against the bearing face of the bung by the nut so as to deform, to exert pressure on the corrugations of the pipe and to provide the necessary seal.
  • the present invention aims to overcome these disadvantages by providing a safe sealing system and able to withstand accidental tearing.
  • the invention relates to a connecting device for an overflow pipe sanitary appliance comprising a rigid body serving as a receptacle and a water recovery pipe to be evacuated characterized in that said rigid bung body comprises two coaxial pipe primers providing an annular cavity adapted to receive said recovery pipe and in that said recovery pipe circumferentially has on its penetrating part in said cavity a groove in which is positioned a seal sealing between said pipe and one of said tube primers.
  • This embodiment has the advantage of ensuring a good seal due to the seal and to ensure through the groove a good positioning of the seal when introducing the recovery pipe into the bung.
  • the establishment of a seal also creates a friction force between the various parts that prevents the accidental tearing of said pipe.
  • the groove of the connecting device is positioned on the outer face of the recovery pipe and is adapted to receive a seal sealing between said pipe and the coaxial female outer tube primer.
  • the outer diameter of the male inner tube primer is equal to or slightly greater than the inner diameter of the recovery tube and ends with a frustoconical portion allowing force introduction of said male inner tube primer in said recovery tube.
  • the groove is positioned on the inner face of the pipe and is adapted to receive a gasket sealing between said recovery pipe and the inner male pipe primer and on the other hand the inner diameter the female outer tube primer is equal to or slightly less than that outside the recovery pipe and ends with a frustoconical portion allowing forcing said pipe with its seal into said female inner tube primer.
  • the connecting device comprises on one of its coaxial tube primers a locking means capable of cooperating with a means for locking the recovery pipe so as to secure said pipe in position in the annular cavity with said rigid body.
  • the recovery pipe has a succession of grooves regularly spaced so as to allow an adjustment of its length by sectioning while having a groove at its end.
  • the groove has the opposite side to that of the end of the pipe entering the annular cavity, the shape of an edge. This configuration makes it possible to hold the seal firmly when fitting the pipe into the female tube primer of the bung
  • the groove has on the side of the end of the pipe entering the annular cavity a frustoconical shape flaring towards said end of the pipe.
  • the locking means installed on the recovery pipe is a groove and the locking means installed on the outer pipe primer is a lug having a projecting portion directed on the side of the recovery pipe and resiliently biased towards its co-operating position. with the throat of said pipe.
  • This configuration makes it possible to secure the pipe in position in the cavity with the bung and to increase the efforts to be made to separate them and thus prevent an accidental tearing.
  • the groove having the function of locking the position of the recovery pipe in position has an edge serving as a stop for the corresponding lug, which has the shape of a flared cone frustum towards the end of the pipe entering said annular cavity. .
  • This connection is capable of receiving a pipe for recovering the overflow water to be discharged 1.
  • the radial connection has the shape of an annular cavity between two tube primers, one of which is called a male whose outer diameter is equal to or slightly greater than the inside diameter of the pipe 1 and the other so-called female 6 whose inner diameter is slightly greater than the outside diameter of the pipe 1.
  • the bottom of this annular cavity is preferably plugged so as to constitute a stop surface for the pipe when it is fitted into the cavity.
  • the pipe 1 is made with successive corrugations so as to give it sufficient flexibility to be curved in the desired direction, whatever the direction, and thus can be implemented, even in places sometimes difficult to access.
  • a seal preferably ring, the dimensions of which fill the portion of the annular cavity left free between the female tube primer 6 and the pipe 1 , is positioned around the pipe 1 near the end intended to enter the annular cavity formed by the two tube primers.
  • the invention proposes making grooves 4 on the outside of the pipe at regular intervals. These intervals are arranged to allow to have a groove at the end of the pipe or at least close to it when it was necessary to cut said pipe before installation in order to adapt its length to the distance available between the evacuation overflow and the drain.
  • the groove 4 located closest to the end of the pipe serves as a housing for the O-ring 3 when it is fitted by fitting the pipe 1 into the annular cavity of the bung 2.
  • the assembly is set up as follows. The operator positions a seal 3 around the pipe 1 in the groove 4 located closest to the end of said pipe 1. It then positions the pipe vis-à-vis the two primers of male and female tubes 5 and 6 grows the pipe equipped with its seal to enter the cavity located between the two tube primers. In the first place the pipe is positioned on the male tube primer 5 whose part facing the pipe 1 has the shape of a truncated cone to facilitate the introduction of said pipe 1.
  • the outer diameter of the male part 5 is equal to or even slightly greater than that of the inner part of the pipe 1 but only exceeds it by a value consistent with the deformations allowed by the elasticity of the material which constitutes the pipe . Due to these diameters very close, the inlet of the male part 5 in the pipe 1 is forced and thus creates a first seal between the pipe and the bung.
  • the end of the pipe is positioned opposite the female part 6 of the bung.
  • the seal 3 is held longitudinally in place by the groove 4 which prevents it from backing up and then does not come to be positioned at the bottom of the cavity. It is also compressed radially between the tube primer 6 and the pipe 1 which ensures a second seal between the pipe and the bung.
  • the configuration of these two sealing systems is such that it allows automatic reinforcement of one of the two seals when the other tends to decrease due to dimensional variations of one or other of the components.
  • the second advantage provided by the invention lies in the multiplication of friction created between the various elements so as to prevent accidental tearing of the pipe on the bung.
  • the press fitting of the pipe on the male part 5 creates a first friction force likely to oppose a certain resistance to tearing accidental.
  • the compression of the seal 3 also has the function of ensuring a friction between the pipe 1 and the tube primer 6 of the bung when it is in place. All this, with adaptations on the relative diameters of the pipe and tube primers that are within the reach of the skilled person, allows to ensure that the pipe can not be torn from the bung by an accidental pulling force which is less than that normally provided for the disassembly of the device.
  • the disassembly of the connection is done in reverse by pulling on the pipe 1 which emerges from the annular cavity between the two tube primers 5 and 6.
  • the seal is held in place on the pipe during this operation by the groove 4 and is thus removed simultaneously with it.
  • the bung 12 has on a part of its female tube primer 16 a locking device adapted to cooperate with a locking device positioned on the pipe 11.
  • this first locking device can have the form of a tab 18 elastically attached to the tube primer 16.
  • the tab is made in the form of a tongue cut on three sides in the lower part of the tube primer 16 and maintained at the latter by the fourth side, which acts as a spring. It also has a portion on its free end that protrudes inside said tube primer and is adapted to engage as a pawl in the locking device of the pipe 11.
  • the pipe 11 has as second locking device, in addition to the groove 4 intended to receive the seal 3, a second groove 17 on which engages the free end of the locking tab 18 .
  • the assembly process is the same as before with the establishment of the seal 3 in the groove 4, the positioning of the pipe 11 vis-à-vis the annular cavity between the tube primers 15 and 16 and with the depressing the pipe 11 in this cavity.
  • the pipe is force-fitted around the male part 15 to achieve a first seal and the seal 3 is held in place during this operation by the groove 4 to ensure, once again, once in place, a second seal.
  • the described configuration in which the first seal is created by a seal placed between the outer part of the pipe 1 and the inner part of the female tube primer 6 can very well be achieved by a seal placed between the inner part of the pipe and the outer part of the male tube primer 5.
  • the second seal would in this case be achieved by a forced introduction of the pipe 1 into the outer tube primer 6.
