Definitions

  • the present invention relates to a coupling for hoses or tubes, such as a coupling of the quick-acting type in ⁇ cluding a sleeve and a nipple for insertion into the sleeve .
  • Couplings of the quick-acting type for use at preferably watering or tapping devices are produced of such high- grade materials, predominantly metals, that they function and remain tight for a very long time and that they, con- trary to plastic devices, possess excellent wearability also because of thBir considerably greater rigidity. This consequently means that such couplings have somewhat higher production costs and thus a higher price. These couplings are thus wished from where they are mounted and a great number is removed by unauthorized people, especially from public buildings. This involves extra costs for new coup- lings. Furthermore the user wanting to employ e.g. a hose is unable to connect it e.g. to a water tap involving loss of working hours and the inconvenience of having to wait until a new coupling has been procured, which costs much more than the individual coupling.
  • the object of the invention is to provide a coupling of the kind named in the introduction where undesired removal is avoided.
  • the coupling according to the invention is characterised by comprising an inner part adapted to be screwed onto a tap, e.g. a water tap, said inner part being partly or completely surrounded by an outer part formed by e.g. a sleeve or a nipple of the quick-acting coupling and at least one of the two parts being provided with a circular groove, where a locking means is engaged in such a way as to enable the outer part to rotate freely in relation to the inner part, at least in the unscrewing direction.
  • a tap e.g. a water tap
  • the part of the coupling attached to the tap i.e. the outer part, only rotates around the inner part if a attempt for its removal is made, and thus cannot be removed without being destroyed and thus made useless.
  • both the inner and outer part may be provided with grooves corresponding to each other and the locking means may be resilient.
  • the locking means may according to the invention be either of the coil spring, flat spring or snap ring type.
  • Fig. 1 shows a cross-sectional view of a securing or inner part belonging to a coupling according to the invention
  • Fig. 2 shows a cross- sectional view of a coupling or outer part in form of a sleeve belonging to the coupling accor ⁇ ding to the invention
  • Fig. 3 shows the securing element of Fig. 1 viewed from be low
  • Fig. 4 shows a cross - sectional view of a securing and coupling part connected to each other.
  • the securing part 1 comprises a unit with an inner or outer thread 2 for securing said part on e.g. a water tap and having a full-length bore 3 for the passage of water and a pair of surfaces 4, whereby said part may be attached by means of e.g. a spanner, a groove with watertight ring 5 and a groove for a locking spring 7 or pin 10.
  • a locking spring 7 e.g. a snap ring
  • a pin or ' alike 10 able to connect the two coupling parts after the mounting in a similar way may also be used.
  • the parts of the coupling to be attached on the tap e.g. a water tap
  • the securing part first being screwed onto the water tap, then e.g. an snap ring kept pressed together in the groove 6 is attached, while the coupling part is slipped over the securing part.
  • the snap ring is released and expands in such a way as to connect the two parts via the grooves 6 and 8 such that a disengagement can only occur by force, since the coupling part normally rotates freely around the securing part without taking it off.
  • the coupling part surrounds the .securing part almost completely thus making it impossible to get a hold on it with a tool with regard to removing said coupling.
  • Fig. 2 it is also possible to mount one or more pins or alike.
  • the coupling part is slipped over the securing part and the two grooves 6 and 8 are opposite each other the pin(s) is/are inserted such as to be- in engagement with groove 8 and at the same time flush with the circumference of the coupling part.
  • the coupling part in the drawings is shown in form of a sleeve of the coupling, but can, of course, also be the nipple. Furthermore mounting with inner and outer thread is possible.
