- roof guttering comprising in combination a gutter body and a connector to be secured to a building adjacent its roof in which the connector has first and second spaced apart arms to project outwardly of the building characterised in that the body is formed at one side thereof with spaced apart, first and second formations accessible externally of the body to cooperate with the respective first and second arms so that after the connector is secured to the building the first formation may be engaged with the first arm and the body rotated to engage the second formation with the second arm as a snap fit to lock the body and the connector together.
- a gutter body 1 is carried by a series of connectors 2 secured to a building facia 3 below its roof 4.
- the body 1 is extruded from an aluminium alloy to be slightly more than semi-circular in section.

Abstract
Description
- This invention relates to guttering for the roofs of buildings.
- There have been many proposals to provide guttering in which a series of spaced apart brackets is secured to a building adjacent its roof and a gutter body is engaged with the brackets by a clipping action sometimes with the addition of a positive fastening device.
- In Australian specification 41273/68 an arrangement is shown for rolled sheet gutters. This includes fairly complex shapes for the brackets and necessitates re-entrant or other gutter formations which prevent the gutter having a smooth, unrelieved, interior of simple cross sectional shape. Furthermore although the arrangement provides for clipping the gutter body to the brackets the eventual engagement of the gutter with its brackets does not hold them tightly together and would permit limited movement between them. Furthermore it is made clear that the gutter may be unclipped from its brackets by a reversal of the assembly movement.
- WO 84/02552 and GB 2145754A both show clipped arrangements involving both side walls of the gutter and requiring part of each bracket to extend across the upper, open, part of the potter. Again, in both cases it is clearly intended that the gutter may be unclipped by reversing the assembly movement.
- According to one aspect of the present invention there is provided roof guttering comprising in combination a gutter body and a connector to be secured to a building adjacent its roof in which the connector has first and second spaced apart arms to project outwardly of the building characterised in that the body is formed at one side thereof with spaced apart, first and second formations accessible externally of the body to cooperate with the respective first and second arms so that after the connector is secured to the building the first formation may be engaged with the first arm and the body rotated to engage the second formation with the second arm as a snap fit to lock the body and the connector together.
- One embodiment of the invention will now be described by way of example with reference to the single figure of the accompanying drawing which shows, partly in transverse section a gutter secured to a building.
- Referring to the drawing a
gutter body 1 is carried by a series of connectors 2 secured to abuilding facia 3 below itsroof 4. - The
body 1 is extruded from an aluminium alloy to be slightly more than semi-circular in section. Itsinner end 5 is formed with a cap 6 having an inwardly hooked part 7 and an outwardly hooked part 8. Theouter end 9 of the body is formed with acap 10 having an inwardly hookedpart 11 corresponding to the part 7. Spaced below theinner end 5, and on the inner side of the body anarm 12 extends outwardly of thebody 1 continuously therealong. - This arm has an
inner part 13 connected with aflat base 14 by aninclined part 15. The outer end 16 of the base is connected to atongue 17 inclined oppositely to thepart 14. The tongue terminates in a nib 18 having aninclined face 18a. Thus a recess is formed above thebase 14 between thepart 15 and thetongue 17. - The connector 2 is also extruded from an aluminium alloy which is then cut into short lengths so that a plurality of such connectors can be secured at intervals along the
facia 3. The connector has abase 19 formed with at least one slot to be secured against the facia by afastener 20. At its upper end the connector is formed with afirst arm 21 terminating in anupward extension 22. The connector has asecond arm 23 spaced from its lower end 24. This second arm has an inner zig-zag portion 25 providing a recess 26 and an outerflat portion 27 having a chamferedend 28. - The
facia 3 androof 4 are indicated diagrammatically and when thegutter body 1 is mounted as described theouter end 29 of the roof extends partially across itsopen end 30. - In practice a series of connectors 2 is secured to the
facia 3 at intervals of say, 1m and a length of gutter body (which may be 5m) has its hooked part 8 engaged over theextensions 22 of the connectors. The body is then pivoted about theextensions 22 until the nib 18 passes theflat portions 27 with a small clearance and engagesshoulders 31 of the zig-zag portions 25. Further pivoting under increased pressure causes the nib 18 to ride up these shoulders and snap into the recesses 26. This arrangement provides a very firm fixing and it will be noted that, when assembled theflat portion 27 closely engages within the recess above thebase 14. - When the gutter assembly is in place screws (not shown) could extend on the
line 37 to secure thearm 12 to some or all of the connectors 2. - With the arrangement described and shown in the drawing it has been found that the force required to unclip the body by reversal of the assembly movement is much greater than the assembly force. Thus the
body 1 can, in practice, be removed from the connectors 2 only by longitudinal sliding. This subordinate feature of the invention can be important when the guttering is of expensive alloy and is used at a location where it might be stolen. - This particularly firm fixing is achieved by virtue of the close engagement of the
inclined face 18a within the recess 26. It will be understood that the corresponding surface of the recess 26 closely engages theface 18a and is disposed at such an angle to thebase 19 that unclipping thebody 1, by rotating it about the upper part of theupward extension 22, requires much greater force than the original assembly movement. While such unclipping is not impossible it means that, for practical purposes, thebody 1 can by removed from the connections only by sliding. - In a modification, not shown in the drawing, the zig-
zag portion 25 is omitted and thearm 12 lies closely along thetongue 17. - At a juncture of two bodies 2 a
bridge 32 is provided. This bridge is also extruded from an aluminium alloy to the same shape as thebody 1 but of sufficiently smaller size both to fit within the body and also so that in a relaxed position (not shown) itsends 33 and 34 are curved slightly towards one another. This arrangement enables one end, say 33, to be engaged under the hooked part 7 with the other end 34 outside the hookedpart 11. Thebridge 32 may then be flexed until its end 34 snaps beneath thehooked part 11 to hold the bridge firmly in place. The bridge has threelongitudinal ribs 35 on its outer surface to engage the inner surfaces ofadjoining bodies 1 and it is expected that a sealant mastic (not shown) will fill thespace 36 between the bodies and thebridge 32. Theribs 35 ensure that the thickness of the body of mastic will be substantially even. - Although as described the
body 1 is substantially semi-circular, other shapes could be provided. Also other metals or plastics could be used for the various parts of the gutter assembly. - In the arrangement described above the
arm 12 provides substantially all the flexing required to achieve a snap-fit between thebody 1 and the connector 2. Other constructions (not shown) are envisaged in which, for example, a locking formation is provided on thebody 1 and thearm 23 is appropriately shaped and flexes to engage it. - With some snap-fit arrangements it would be possible to roll form the
gutter body 1. - With the described arrangement the
continuous arm 12 provides a pleasing appearance from below and also prevents access to thefastening 20 for the connectors 2. - It will be understood that the slot formed in the
base 19 of the connector 2 for thefastener 20 enables some adjustment to be made so that a number of connectors can be accurately aligned on thefacia 3. Packing pieces may be used beneath selected connectors to allow for irregularities in the facia surface. Alternatively thebase 19 could be in two parts (not shown) in a manner well known, for example, for other mounting brackets to provide adjustment both in the plane of the facia and normal thereto. - In addition the snap-fit arrangement could include various positions of engagement. In the described construction this could be achieved by providing a plurality of recesses 26 along the
second arm 23 so that the nib 18 can engage any one of them. Such an arrangement would provide additional flexibility in fixing thegutter 1 in circumstances in which it is difficult accurately to align the connectors. - Thus the present invention provides guttering that can include some or all of the following features.
- 1. All parts of the guttering can be extruded from light metal alloy.
- 2. The appearance of the guttering from below is aesthetically pleasing.
- 3. The interior of the gutter body is unencumbered by fixing devices and presents a smooth profile so that clogging by leaves or other debris is minimised.
- 4. There is freedom to have the potter body of different cross sectional shapes.
- 5. The snap-fit between the body and connectors is particularly firm and can be designed so that unclipping by reverse movement is difficult and, in practice, the body needs to be removed from the connectors by sliding action.
Claims (8)
- Roof guttering comprising in combination a gutter body and a connector to be secured to a building adjacent its roof in which the connector has first and second spaced apart arms to project outwardly of the building characterised in that the body is formed at one side thereof with spaced apart, first and second formations accessible externally of the body to cooperate with the respective first and second arms so that after the connector is secured to the building the first formation may be engaged with the first arm and the body rotated to engage the second formation with the second arm as a snap fit to lock the body and the connector together.
