DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
(1) Field of the Invention
THIS INVENTION relates to a connector for connecting vessels or pipes together.
(2) Description of the Prior Art
There are many applications where vessels or pipes must be connected to pipework already installed. One example is the connection of baths, showers and urinals to drainage pipework which is installed during the construction of buildings.
It has been found in practice that forming an effective connection between such a vessel and such prelocated pipework is extremely difficult. Firstly, it is rare to find that the inlet or outlet of the vessel is accurately aligned with the pipework. Secondly, the connections generally available are rigid and cannot accommodate any relative movement between the vessel and the pipework at the connection point. Should any movement occur, e.g. when a person steps into a bath, the sealing of the connection may be damaged or destroyed. Thirdly, the connection can only be made after the vessel is installed and, as access to the connector is often restricted, this makes the connection operation very difficult.
In an attempt to overcome the problem of misalignment between the inlet or outlet of the vessel and the pipework, a number of solutions have been proposed. One of these which has come to the applicant's attention is that disclosed in U.S. Pat. No. 4,014,053 (Jones). The connector disclosed in that Patent uses an offset flange having an opentopped body to which is fitted a cover selected from a range of covers having holes at relative dispositions in the cover so that the plumber selects a cover which will provide the closest alignment between the hole in the cover and the inlet or outlet of the vessel. This connector is not satisfactory as it requires the plumber to have a supply of such covers (allowing for misalignment in two axes) and access to the connector may be restricted.
SUMMARY OF THE PRESENT INVENTION
It is therefore an object of the present invention to provide a connection which can be easily and simply sealed.
It is a preferred object to provide a connection which will allow some relative movement between the vessels or pipework without damaging or destroying the seal.
It is a further preferred object to provide a connector for connecting vessels or pipes which are misaligned in at least one axis.
It is a still further preferred object to provide a connector which can be assembled to form a connection where the connection point is not readily accessible and the connection operation may be carried out from inside the vessel.
Other preferred features will become apparent from the following description.
In one aspect the present invention resides in a connector for connecting vessels or pipes comprising:
a first connection member adapted to be connected to a first vessel or pipe;
a second connection member adapted to be connected to a second vessel or pipe; and
clamping means adapted to secure said first and second connection members together; characterized in that:
said second connection member has a portion of greater diameter than the diameter of said first connection member; and
a wall closing the said portion, said wall being adapted to have a hole formed therein to receive said first connection member to form the connection between said vessels or pipes.
Preferably the connector further includes resilient sealing means surrounding the hole formed in the wall and adapted to be compressed between said first and second connection members to form a fluid-tight seal therebetween.
Preferably the resilient sealing means has an annular body formed of resilient material, e.g. rubber, neoprene or plastics material, a peripheral groove in said body to receive and engage an outlet of the first vessel or pipe; and an internal laterally extending peripheral lip adapted to engage the wall of the second connection member.
Preferably the clamping means includes:
a clamping bracket adapted to engage the face of the wall spaced from the first connection means; and
fastening means interconnecting said first c
