Definitions

  • the present disclosure relates to a connector assembly for indoor taps. More specifically, the present disclosure relates to a spring-loaded water stop which overcomes major demerits, particularly for application with the indoor taps.
  • Conventional connector assembly for a hose generally makes use of a means to check flow of water through the hose. But such means prove to be less efficient for a disassembled state of a connecting tool (say a sprayer) from the hose.
  • a pressure-based“water stop” is used as the means to check the flow, however, this leads to an undesirable operation because of various reasons. Firstly, there can be an erratic or unreliable pressure from the water inside the hose or the connector assembly leading to an undesirable operation of the“water stop”. Such pressure may also lead to undesirable damage or pose security risk for the connector assembly or any component thereof.

Further, the stopper element allows water to flow through the connector assembly in the open position.
  • the connector assembly is characterized in that a second biasing member is coupled to the inner cover member. The second biasing member is adapted to bias the stopper element in the closed position.
  • the stopper element slides to the open position when the adapter element is engaged with the inner cover member. Moreover, the stopper element slides to the closed position when the adapter element is disengaged with the inner cover member.

Abstract

Selon l'invention, un ensemble raccord (100) servant à raccorder un tuyau flexible (110) à une prise d'eau (120) comprend un élément adaptateur (200). L'élément adaptateur (200) est reçu par un élément couvercle intérieur (210). Une saillie (308) ménagée dans un espace annulaire entre l'élément couvercle intérieur (210) et un élément couvercle extérieur (220) maintient l'élément adaptateur (200) en place par l'action de sollicitation d'un premier élément de sollicitation (310). Un élément d'arrêt (320) permet sélectivement un écoulement fluide à travers l'ensemble raccord (100). L'élément d'arrêt peut coulisser entre une position ouverte et une position fermée. Un second élément de sollicitation (324) sollicite l'élément d'arrêt (320) vers la position fermée. L'ensemble raccord (100) est caractérisé en ce que l'élément d'arrêt (320) permet un écoulement fluide à travers l'ensemble raccord (100) lorsque l'élément adaptateur (200) est en prise avec l'élément couvercle intérieur (210). L'élément d'arrêt (320) bloque l'écoulement fluide à travers l'ensemble raccord (100) lorsque l'élément adaptateur (200) est désolidarisé de l'élément couvercle intérieur (210).
