  • the recess in the external wall of the inner tubular member may be a circumferential recess and the slot in the outer tubular member may be a circumferential slot.

  • FIG. 1 shows the components of the connection of Figure 1;
  • Figure 3 is a cross section through the connection of Figure 1;
  • Figure 4 shows a second embodiment of the connector.
  • Figure 5 is a partial cut away view of an assembled connector between a pipe and a radiator fitting
  • Figure 6 is an exploded view of another form of coupling which may be used on a free end of either the first or the second tubular member;
  • Figure 7 is a cross section through another embodiment of the connector.
  • FIGS. 1 to 3 depict a connector for tubular members 10, 12 comprising:
  • first tubular member 10 having an internal cylindrical wall 14 terminating at its outer end with an outwardly directed annular abutment 16;
  • second tubular member 12 adapted for sliding engagement into the first tubular member 10 and having an outwardly directed annular flange 18 that, in use, engages the annular abutment 16;
  • annular sealing means 20a, 20b providing a seal between the first 10 and second 12 tubular members
  • securing means 22 for releasably holding the flange 18 against the abutment 16.
  • the annular sealing means may comprise a resiliently deformable material positioned either in the internal wall of the first tubular member 10 or in the external wall of the second tubular member 12.
  • the preferred arrangement is shown in Figures 1 to 3 wherein the sealing means comprises two '0' rings 20a, 20b, which are retained in annular grooves in the external wall of the second tubular member 12.
  • the '0' ring or '0* rings used in the invention may be of any material, for example, selected so as to be suitable to the application or location and, for example, may comprise material resistant to various forms of chemical susceptibility or chemical attack.
  • the first tubular member 10 has an internal thread 24 and the securing means 22 is an externally threaded nut whose thread 26 matches the thread 24 of the first tubular member 10.
  • the first tubular member 10 may comprise the inlet to a central heating radiator.
  • the thread 24 could instead of the nut 22 receive a conventional threaded pipe connection.
  • the second tubular member is inserted into the first tubular member 12 so that the flange 18 engages the abutment 16, this arrangement being maintained by the securing means 22 which, once in full threaded engagement with the first tubular member 10, abuts the flange 18.
  • Connectors of this type are relatively cheap to manufacture, easy to assemble and disassemble and, importantly, compatible with radiators of existing design.
  • An additional advantage is that the connector allows rotation of the radiator connection 10 about the longitudinal axis of the tail pipe 12, making the connector compatible with pivoting radiators of the type described in UK Patent Application No. 9509955.2. This feature is due to the fact that the fit between the securing means 22 and the second tubular member 12 is loose enough to permit rotation of the former against the latter without loss of the seal.
  • FIG. 4 A further embodiment of the invention is shown in Figure 4, in which the first tubular member 10 is the inlet pipe to a water tap 28 and has an external thread
  • abutment 16 is the outer end of the pipe itself.
  • the second tubular member 12, the flange 18 and the annular sealing means 20a, 20b are as previously described.
  • the securing means 22 is a castellated nut having an internal thread 32 which matches the thread 30 of the first tubular member 10 and whose fingers are flexible to enable it to be pushed onto the member 10.
  • the securing means 22 can be formed, for example, from any suitable metal or plastics material, although plastics materials are often preferred. Where the securing means 22 is provided with an internal thread 32, the securing means can be screwed onto the first tubular member 10. If, however, the fingers of the securing means 22 have sufficient flexibility, for example, if the securing means is formed from a suitable flexible or resilient plastics material, the securing means can simply be pushed onto the first tubular member 10, perhaps with a single turn or twist to give added security.
  • FIG. 5 shows an assembled junction between a pipe 112 and a pipe connector 110 for a radiator having a locating pin 114 positioned along the longitudinal axis of the pipe 112 which is received by the connector 110.
  • the pipe connector 110 may have an elbow joint configuration, wherein the pipe 112 enters the pipe connector 110 perpendicular to the pipe connector- radiator connection axis.
  • the connector may be of a "1" piece configuration, in which there are two collinear pipe connector-radiator connections perpendicular to the pipe entry axis. The latter configuration is used for double- or triple-leaved radiators.

  • the pipe 112 has two "0" rings 120a and 120b fitted thereto, and an annular flange 128 in the external wall thereof. An externally threaded and knurled securing nut 122 engages the thread on the end region of the pipe connector.
  • the pipe is also connected to a control valve (not shown).
  • FIG. 6 shows a demountable coupling which may be used on a free end of either the first or the second tubular member.
  • the junction 201 comprises a pipe 202 which is received within a stainless steel or low carbon steel body 203 of a pipe connector.

  • the demountable junction is assembled by sliding the pipe 202 telescopically into the body 203 of the connector, whereupon the 0-ring 208 seals between the pipe 202 and the internal wall of the body 203 of the connector.
  • the pipe 202 is inserted into the body 203 until the lip of the valve tail abuts against the shoulder stop 214.

Abstract

Connecteur pour éléments tubulaires. Le connecteur comprend un premier élément tubulaire (10) présentant une paroi intérieure cylindrique aboutissant à son extrémité extérieure avec un aboutement annulaire (16) orienté extérieurement. Un second élément tubulaire (12) est adapté pour s'engager par coulissement dans le premier élément tubulaire et il présente un rebord annulaire (18) orienté extérieurement, lequel, en utilisation, vient au contact de l'aboutement (16). Un ou plusieurs joints toriques (20a, 20b) forment un joint entre les premier et second éléments tubulaires. Des moyens de fixation se présentant sous la forme d'un écrou fileté (22) maintiennent le rebord (18) contre l'aboutement (16). Le second élément tubulaire (12) est rotatif par rapport au premier élément tubulaire (10) lorsque les deux éléments sont couplés ensemble.
