Abstract

A connector 1 for connecting ducting elements together comprising a body 2 which may be blow moulded and preferably has a crucifix form with an extended limb 4. Means to articulate the body are included and may take the form of bellows or concertina-type arrangement 3 on limb 4. A position 7 may be included to mount ancillary elements such as a fan. Holes 8 may be provided to attach the connector 1 to a substrate and pads 9 may also be present. The limbs 4, 5, 6 may be formed blind and may be opened by removing the end to form either a male or female connection. In use the connector can connect ducting elements in different planes up to an angle of 45{ and is suitable for fluid ducting systems particularly gas ducting systems.

Description

DUCT1NG The invention relates to ducting, and particularly to a connector for connecting ducting elements together.
Ducting is often used in ventilation apparatus, for example in kitchens, domestic and commercial, where fumes are carried away from say a hob or cooker. Such systems are also often used in other situations, such as in a bathroom or shower-room, and in air conditioning systems.
Such ducting systems are often incorporated in the structure of a building, and are usually installed in order to conduct gases to a point of disposal, for example outside a room or building in which they are installed. The systems often therefore have to provide for different duct elements being at different angles and heights. This usually means that expensive cutting and bending has to be carried out on site, or a variety of connectors have to be provided. This is expensive.
It is an object of the invention to seek to mitigate these disadvantages.
According to a first aspect of the invention there is provided a connector for connecting ducting elements together, comprising a body and means of the body adapted to articulate the body so that ducting elements can be connected in different planes.
Using the invention it is possible to provide a connector which provides for substantially universal connection of ducting elements in a ducting system.
The body may suitably have an elongate configuration. This makes for ease of construction and use. For particular effectiveness the articulation means may be positioned adjacent one end of the body.
The articulation means may comprise a bellows -or concertina-type means. This provides a particularly effective construction as the means can be extended in a particular desired direction, and can be maintained in the extended attitude.
The body may be integrally formed by moulding, a preferred method of forming being blow moulding. This is a relatively simple forming method, and can provide repeatability in production of a plurality of identical connectors.
There is suitably provided in the connection a mounting position for a device such as a fan.
The said position may suitably be defined by a knock-out portion of the body. This allows for flexibility in use in situ as a supplemental device can be mounted in situ but if such a device is not to be included, the physical integnty of the connector is maintained so fluid flow is not compromised.
The body may be cruciform in plan. The limbs of the body may be formed blind during moulding. This provides for them to be opened in situ.
The end of the limbs may be adapted for a male or female connection with separate ducting elements.
According to a second aspect of the invention there is provided a ducting system, including ducting elements and a connector as hereinbefore defined connecting adjacent elements of the system together.
A connector embodying the invention is hereinafter described, by way of example, with reference to the accompanying schematic drawings.
Fig. I is a perspective view of a connector embodying the invention from one side; and Fig. 2 is a perspective view of the connector of Fig. 1 from the opposite side.
Referring to the drawings, there is shown a connector I for connecting ducting elements (not shown) of a ducting system together, the connector 1 comprising in the embodiment a blow moulded body 2 of cruciform configuration and means 3 of the body 2 adapted to articulate the body 2 so that ducting elements can be connected in different planes.
The body 2 is generally elongate, having a relatively longer limb 4 and two relatively short transverse limbs or projections 5, 6 to provide the cruciform configuration. In the embodiment shown, the articulation means 3 is intermediate the longer limb 4 and positioned adjacent but set back from one end of the longer limb 4. The articulation means 3 is of bellows -or concertina-type configuration so that when extended in a plane to left or right of the length of the longer limb 4, or up or down relative thereto through the plane of the paper as viewed, the connector I can connect ducting elements in different planes, suitably up to an angle of 45° to the longitudinal axis of the body 2 as defined by the length of the longer limb 4. When the articulation means 3 is so expanded, it will be understood that it is maintained in the expanded position by the inherent memory' of the material from which the connector is made, typically PE, and by the position of the ducting element(s) which the connector 1 is connecting in the different planes.
The connector 1 has a position 7 for mounting ancillary equipment such as a device such as a fan (not shown) the position 7 being defined by a knock out' part formed integrally during the integral blow moulding process. If an ancillary device is to be mounted, an installer merely has to knock out the knock out part 7 in situ. There are holes 8 for securing the blow moulded connector to the underside of a substrate such as a floor above the device. There are also pads 9 which are formed during the blow-moulding process, and are just big enough to prevent "wobble" or canting of the device in Situ and small enough to avoid surface irregularities of a floor to which the device is fixed via the holes, which are not shown in Fig. 2.
The limbs 4, 5, 6 are formed blind as shown at 10. They are adapted to be opened on site by a simple expedient such as sawing off the end. This opens up the connector at a desired position for fluid, suitably gas, flow.
This blind end provision also provides flexibility in use as it is only necessary to open up those limbs 3, 4 or 5 which are to be connected with a ducting element. Moreover, the limbs 3, 4, 5 can provide both for a male or female connection with ducting elements, being stepped at 11 to provide for an easy push fit.
The connection is typically of 1 to 1.5 metres in length, and, as mentioned, can be used in ducting systems for fluid flow, e.g. for flow of gases or liquids, though the connector is particularly suitable for use in ducting systems for ducting of gases.
A connection shown and described herein with reference to the drawings can provide for universal connection of ducting elements of a ducting system.
