The valve member 18 is biased to a closed position by a spring 19, and is moveable to an open position by the actuator member 39, when the connection member 10 is connected to the end fitting 30, such that fluid can pass through the connection member 10. A part 27 (see fig. 3) of the connection member 10 has a lower melting point than the housing 11, such that when the lower melting point part 27 softens, the spring 19 effects relative movement between the connection member 10 and the end fitting 30, thus closing the valve 17. The lower melting point port is preferably solder.

Description

Title: Connection Member
Description of Invention
This invention relates to a connection member, which is connectable at one end to a conduit and releasably connectable at its other end to an end fitting, which end fitting is connectable to a further conduit.
More particularly, but not exclusively, this invention relates to a connection member for connection to a gas supply conduit or pipe, although it must be appreciated that the invention could be utilised for other fluids, such as liquids.
In use, a gas conduit or hose extends from a gas appliance, such as a cooker, with its end remote from the cooker having an end fitting and being engageable with a connection member of a gas supply conduit or pipe.
Typically, the connection member is formed as one of an inter-engaging plug and socket connection, with the end fitting being formed as the other thereof.
To connect the connection member and end fitting together, the interengaging plug must be inserted into the socket and then, conventionally, a portion of one part must be rotated relative to the other part about a common longitudinal axis of both parts. The relative rotation of the connection member and the end fitting engages at least one projecting formation on one part with a corresponding recess formation on the other part. Such a connection is commonly known as a bayonet-type connection.
The connection member of the gas supply pipe conventionally includes a valve which is spring loaded onto a seat to prevent outflow of gas from the gas supply pipe. Known end fittings are made from metal, such as brass, and have an integrally cast or machined metal projection which, when the end fitting is engaged with the connection member, forces the valve off its seat, in Al 1304GB order to allow gas to flow from the gas supply pipe, through the connection member and the end fitting, into the hose and then to the gas appliance.
A problem with this arrangement is that in the event of, for example, a fire, although the hose may be damaged along its length, the metal end fitting, including the metal projection thereof, and the connection member are likely to remain undamaged. There is thus the danger that the damaged hose may continue to be used or be re-used as the end fitting and connection member remain unaffected and will thus allow gas to flow to the damaged hose from which it may escape.
According to a first aspect of the invention there is provided a connection member specifically adapted to be connectable at one end to a conduit and releasably connectable at its other end to an end fitting with an actuator member, the connection member including a housing and valve having a valve member, which valve member is biased to a closed position by a spring, said valve member being moveable to an open position by the actuator member when the connection member is connected to the end fitting, such that fluid can pass through the connection member, wherein a part of the connection member has a lower melting point than the housing, such that when the lower melting point part softens, the spring effects relative movement between the connection member and the end fitting, thus closing the valve.
The lower melting point part may be provided in a recess in the housing, e.g. a channel formation. The recess or channel formation, as the case may be, may have a longitudinal axis substantially parallel to a longitudinal axis of the connection member, e.g. coaxial with the longitudinal axis of the connection member.
The connection member may include two of said lower melting point parts.
AII3O4GB The two lower melting point parts may be positioned one at each side of the housing, e.g. positioned at opposite sides of the longitudinal axis of the connection member.
The connection member may include an abutment member which is connected to the housing by the lower melting point part.
The abutment member may be provided in the recess in the housing.
Preferably, the connection member includes two of said abutment members, one positioned at each side of the housing.
When the lower melting point part(s) softens, each abutment member may be moveable relative to the housing. Where each abutment member is provided in a recess in the housing, each abutment member may be moveable along the recess.
When the connection member is connected to the end fitting, the lower melting point part(s) and/or the abutment member(s), as the case may be, may abut a respective projecting formation provided on the end fitting.
When the lower melting point part(s) softens, each abutment member may be held relative to the end fitting by the projecting formation(s) on the end fitting.
The lower melting point part(s) may be a fusible alloy, such as a solder.
The invention will now be described by way of example only with reference to the accompanying drawings, of which:- Al 1304GB Figure 1 is a side view of a connection member in accordance with the present invention, connected to an end fitting, with a valve of the connection member in an open position; Figure 2 is a side view of a connection member in accordance with the present invention; Figure 3 is an end view of the connection member of figure 2; and Figure 4 is a side view of the connection member and end fitting of figure 1, but with the valve in a closed position.
Referring to the figures, the connection member 10 includes a housing 11 having a first end 12 connected to an end fitting 30 and an opposite, second, end 13, which is, in use, connected to a gas supply pipe (not shown) by means well known in the art.
The housing 11 of the connection member 10 is generally cylindrical and is substantially rotationally symmetrical about a longitudinal axis 42 thereof. The housing 11 has a passage 14 therethrough for gas received from the gas supply pipe (not shown). The passage 14 has a first section 14a extending through the first end 12 and a second section 14b, forming a valve chamber of a valve 17 (discussed later), extending through the second end 13. The sections 14a and 14b are coaxial with a longitudinal axis 42 of the connection member 30, with the section 14a having a smaller diameter than the section 14b. The sections 14a and 14b are connected by a tapered valve seat 20, the purpose of which will be discussed in greater detail hereinafter.
A remote portion of the first end 12 of the housing 11 has a radially outwardly projecting annular flange 12a, which is spaced from a main part of the housing 11 by an annular recess 15. The annular flange 12a, when viewed from its Al 1304GB end (see figure 3), has four recesses 26 spaced at 900 intervals around the axis 42 of the connection member 10. Two of the recesses 26 which face each other (i.e. which are spaced 180 from each other around the axis 42) each support an abutment member 16. The abutment members 16 are fixed in their respective recess 26 by a part 27 which has a lower melting point than the housing 11. In this example the part 27 is a fusible alloy, such as solder.
A part of each abutment member 16 closest to the flange 12a of the housing 11 has a semi-circular recess 16a (as viewed in figure 2), the purpose of which will be discussed in greater detail hereinafter.
The valve 17 has a valve member 18 which is slidable in the section 14a. The valve member 18 is biased to a closed position so as to engage the tapered valve seat 20 by a spring 19. The spring 19 is supported in the section 14 and one end thereof abuts a radially inwardly projecting end flange I 3 of the second end 13. The other end of the spring 19 is received over a formation on a part of the valve member 18 which is remote from the valve seat 20. A part of the valve member 18 facing the valve seat 20 supports an annular valve seal 21 which provides a fluid- tight seal between the valve member 18 and the valve seat 20 when the valve is in a closed position, so that fluid, in this example gas, cannot pass through passage 14 of the connection member and into the end fitting 30.
The valve member 18 has a main body which is cylindrical (and is coaxial with the axis 42) and has an external diameter slightly smaller than that of the section 14a. A free end (i.e. opposite to the connection of the spring 19 thereto) of the main body of the valve member 18 has a recess 18 which faces towards the end fitting 30. The recess 18 communicates with four radially spaced apertures 18b in a circumferential wall of the main body of the valve member 18. The apertures I 8b are spaced at 90 intervals around the axis 42.
Al 1304GB The apertures 1 8b are spaced from an entrance to the recess I 8, such that when the valve member 18 is in an open position (see figure 1), gas can pass through the section 14b of the passage 14, through the apertures 18b, through the recess 18a and into the end fitting 30. Closure of the valve member 18 ensures that the apertures 18b are not in fluid communication with the section 14b of the passage 14.
Moving on to the end fitting 30, which is of known form, this has a generally L- shaped housing 32 (when viewed from the side as shown in figures 1 and 4).
The L-shaped housing 32 has a first part 33 and a second part 34 which are connected transversely to each other at corresponding ends. Both parts 33, 34 are substantially cylindrical, with the second part 34 (as shown in figures 1 and 4) having a longitudinal axis coaxial with the axis 42 of the housing 11 of the connection member 10.
Extending substantially centrally through the parts 33 and 34 is a passage 35, which is again L-shaped in side view, and corresponds to the shape of the housing 32. A free end of the first part 33 is connected to a hose 36, which hose 36 extends to a domestic appliance (not shown).
A free end 39 of the second part 34 supports a rotatable member 38, which is free to rotate about the axis 42. The rotatable member 38 has a circumferential wall 38b, one end of which is connected to an end wall 38a.
The end wall 38 has an aperture 38c to receive the free end of the second part 34. The rotatable member 38 is held relative to the second part 34 by a clip 40 which is received in an annular recess 41 in the second part 34, and which sandwiches the end wall 38a between it and a shoulder 37 on the second part 34. The free end 39 of the second part 34 also acts as an actuator member to push the valve member 18 off its valve seat 20 when the connection member 10 is connected to the end fitting 30.
Al 1304GB A free end of the circumferential wall 38b of the rotatable member 38 supports two projecting lugs 43, which are spaced 1800 from each other around, and extend radially inwardly towards, the longitudinal axis of the rotatable element 38.
The free end 39 of the second part 34 includes an annular seal 46 which is received in an annular recess 47. The purpose of the annular seal 46 is to provide a fluid-tight seal between the second part 34 and the section 14 of the passage 14 in the housing 11 of the connection member 10.
To connect the connection member 10 and the end fitting 30 together, the end fitting 30 is moved towards the annular flange 12a of the housing 12 and the free end 39 of the second part 34 of the end fitting 30 is inserted into the section 14a of the passage 14. This continues until the free end 39 of the second part 34 engages the valve member 18. Further movement of the free end 39 of the second part 34 through the section 14a of the passage 14 pushes the valve member 18 away from the valve seat 20, against the force of the spring 19.
As the free end 39 of the second part 34 is pushing the valve member 18 off its seat 20, the projecting lugs 43 enter the empty recesses 26 on the annular flange 12a of the housing 11 of the connection member 10 until a free end of the rotatable member 38 abuts a shoulder 1 la on the housing 11.
To lock the end fitting 30 to the connection member 10, the rotatable member 38 is rotated about 900, until the lugs 43 are positioned behind the abutment members 16. The end fitting 30 is then released and the force of the spring 19 urges the end fitting 30 away from the connection member 10, which in Al 1304GB turn engages the lugs 43 with the semi-circular recesses 16a, thus holding the end fitting 30 relative to the connection member 10.
Turning now to figure 4. In the event of, for example, fire, the hose 36 may be damaged along its length by excess heating, which could allow gas to escape therefrom. However, the connection member 10 of the present invention addresses this problem by providing the abutment members 16, which are connected to the housing 11 of the connection member 10 by a part 27 of solder which has a lower melting point than the housing 11.
As the connection member 10 becomes hotter, the solder 27 softens. As a result of the force being applied by the spring 19 to bias the valve member 18 to a closed position, the connection member 10 moves away from the end fitting 30, with the abutment members 16 sliding along their respective recesses 26 due to being held relative to the end fitting 30 by the lugs 43.
This continues until the valve member 18 lies in a closed position, such that no gas can flow through the connection member 10.
By the provision of the abutment members 16, which are connected to the housing 11 of the connection member 10 by a part 27 which has a lower melting point than the housing 11, the danger that the damaged hose 36 may continue to be used or be re-used is minimised, because as soon as the solder 27 softens due to excess heat caused by the fire, the valve member 18 moves to a closed position. Of course, it must be appreciated that one abutment member only could be utilised. Also, the abutment member itself could be of a material which has a melting point lower then the housing.
By the use of the term "solder" in the above example, we mean to include all fusible alloys which can be used to join less fusible metals together. Two examples of such solders which can be used in the present invention are tin and lead, and copper and zinc solders. It must, however, be appreciated that Al 1304GB the lower melting point part could be a material other than a solder, so long as it has a melting point lower than that of the housing of the connection member.
When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
