Details

Inventors: Houseman, David G.; Binding, Gary J.;
Assignee: John Deks Australia Pty. Ltd (Bayswater, AU)
Primary Examiner:

Attorney, Agent or Firm:

A flashing device for use on a building roof to seal about a pipe passing therethrough, comprising a sleeve of rubber or the like through which the pipe may pass with the upper end of the sleeve in sealing contact with the periphery of the pipe. A pair of rigid ring members are provided at the lower end of the sleeve, with a portion of the sleeve located between the ring members. The ring members being adapted to interlock together to compress the portion of the sleeve therebetween into sealing relation with a sheet material also located between the ring members.

DETAILED DESCRIPTION We claim: 1.
A device for flashing about a pipe or conduit passing through a roof or wall, a first member having an aperture therethrough for a pipe or conduit to pass through and a continuous first abutment surface extending about said aperture, a second member having an aperture therethrough for the pipe or conduit to pass through and a continuous second abutment surface extending about said aperture, said apertures and abutment surfaces being arranged so that when the first and second members are assembled to a pipe or conduit that extends through the respective apertures, the first and second abutment surfaces are in an opposing face to face substantially parallel relation substantially transverse to the axis of the pipe or conduit, means to secure the first and second members together in said assembled relation with a sheet of flexible material therebetween and through which the pipe or conduit also extends and a sleeve of flexible resilient material adapted at one end for attachment to the first member so that a pipe or conduit extending through the first and second members also extends through the sleeve, the other end of the sleeve being adapted to sealably engage the external surface of the pipe or conduit extending therethrough, said one end of the sleeve including a portion located in use to be compressed between the sheet and one of the members when the first and second members are secured together in said assembled relation.
2.
A device as claimed in claim 1 wherein said one end of the sleeve is adapted to be attached to the first member so that in use said portion of the sleeve is located between the abutment surfaces of the first and second members.
3.
A device as claimed in claim 2 wherein the portion of the sleeve is an annular bead seated in an annular bead groove formed in the first member substantially co-axially with the aperture in the first member.
4.
A device as claimed in claim 2 wherein the perimetal edge of the first member is received in a recess in the internal surface of sleeve
