FR2649468A3 - FAST COUPLING FEMALE FITTING FOR FLEXIBLE PIPES - Google Patents

Abstract

This connector comprises a rigid body 1 crossed by an axial slot 2 and which carries at one end a threaded ring 3 serving to fix the connector on the end of a flexible pipe and, at the other end, a sliding sleeve 4 serving to actuate hooking means capable of hooking the connector to a male connector which fits into the axial slot 2. The sleeve 4 consists of a rigid part 5 on which is wound an annular tire 6 of rubber material , which eventually wears a rough finish.

Description

1. The present invention relates to a coupling

  female quick coupling oour flexible hoses.

  The known types of female connectors of this gen-

  are mainly used for the connection between

  flexible hose lengths for watering

in the field of gardening.

  A connector of the type described in Italian Pat. No. 1,132,144 of the same applicant includes a

  main body traversed by an axial light and which carries

  at one end a threaded ring for attaching the connector to the end of a flexible hose, and at the other end a sliding mancnon for actuating suitable hooking means capable of catching the hose.

  connection to a male connector which fits into said

axial core.

  Normally, both the main body and

  the ring and the sleeve are made of plastic

  that, for example ABS. This sometimes com-

  disadvantages, especially as regards the facilitation

  the grip and actuation of the sleeve and the risk of shock damage to the free end of the sleeve, particularly when the connector is attached to a hose and is not attached to a male connector .

  In addition, the realization of the connection in one

  the same material offers only weak possibilities

  creation of particular aesthetic effects, for example

  ple in the form of color combinations.

  The purpose of the invention and to solve the problems

  my aforementioned grip and sensitivity to the impact of the sleeve and possibly to offer the possibility of achieving aesthetic effects that it was impossible to obtain

until now.

  According to the invention, this object is achieved with a female coupling with quick coupling for pipes

  hoses comprising a rigid body traversed by a light

  axially and carrying at one end a ring

  tee for attaching the connector to the end of a flexible hose and at the other end a sliding sleeve for actuating suitable hooking means capable of hooking the connector to a male connector that snaps into place in said axial lumen, characterized in that

  said coupling consists of a rigid part on the

  Said annular bandage is advantageously

  made of a rubbery material and advantageously

  As can be seen by referring to the
