Abstract

Tiles projecting at a roof end can be finished off with a verge capping system incorporating capping sections 4 joined end to end with clips 5. The clips 5 interfit longitudinally with the capping sections 4, for example by insertion into slots 20 in the section ends, so that the sections 4 are held securely together against transverse separation. The sections 4 have bottom walls 8 which are fixed on to the roof battens (2 Figure 3) and the tiles (1 Figure 3) fit between these bottom walls 8 and overhanging top walls 7. <IMAGE>

Description

SPECIFICATION Verge capping system This invention relates to a verge capping system for finishing off ends of tiled roofs, particularly although not exclusively roofs tiled with flat slate tiles.

With a conventional form of tiled roof having gable ends, the tiles project slightly at such ends and are finished off, to improve the appearance and ensure adequate sealing, with cement and wooden barge boards. It is also known to use plastics capping sections which are cut to length, joined end to end with clips and fitted around the projecting tile ends. These plastics sections can be particularly quick and easy to install. However, there is the problem of ensuring that the resulting structure is both adequately robust and of acceptable appearance.

An object of the present invention is to provide a verge capping system which may be particularly robust and attractive.

According to one aspect of the invention therefore there is provided a verge capping system for application to tiles projecting at a roof end, said system comprising a plurality of elongate capping sections arranged to be fitted around said projecting tiles, and a plurality of clips each capable of retaining engagement at each side thereof with a respective capping section end whereby said sections can be joined end to end with said clips, characterised in that said clips are arranged to interfit longitudinally with said capping section ends to a limited extent longitudinally as determined by abutting surfaces on said clips and said capping sections whereby such joined capping sections are securely retained against transverse separation thereof.

With this arrangement a particularly robust interconnection and reinforcement of the capping sections can be achieved.

In a particularly preferred embodiment, the longitudinal interfitting arrangement is achieved by sliding the clips longitudinally relative to the capping sections so that cooperable configurations interengage with each other so as to prevent transverse separation of the clips and sections even on flexing thereof. Thus, for example, the clips may have configurations insertable into slots in the ends of the capping sections.

With regard to the said abutting surfaces, these may be defined by the ends of the abovementioned slots in conjunction with the ends of the insertable clip configurations. Alternatively or additionally the clips may have a transverse intermediate wall or ridge between the said opposite sides of the clip, which wall or ridge provides an abutment for the ends of the capping sections.

Free ends of the capping sections may be finished off by application thereto of end pieces which may comprise the joining clips, especially where these have intermediate walls as aforesaid.

Alternatively, specially adapted end pieces incorporating end walls may be used. A clamp screw or other fixing arrangement may be provided to hold the end pieces in position.

With regard to the sections these may be generally of C-section having a side wall and opposed top and bottom walls extending transversely to the side wall, the arrangement being such that in use the bottom wall is fixed beneath the tiles (e.g. by nailing or screwing to the usual roof battens) and the top wall fits on top of the tiles. Holes or slots may be provided at regular positions in the bottom wall to receive nails or screws or other fixing devices. The top wall may be inclined downwardly, towards the bottom wall. A water drainage groove or channel may be defined in the bottom wall adjacent the side wall.

Most preferably each section also has a downwardly projecting wall beneath the bottom wall which may improve the decorative appearance e.g.

by simulating a barge board. This projecting wall may be inset relative to the said side wall, preferably so as to be level with the innermost side of the aforesaid drainage groove or channel. There may be a transverse inwardly directed wall at the bottom end of the projecting wall to promote structural strength e.g. by resting against a building wall beneath the projecting tiles. A tubular member may be provided along the inside of the projecting wall to provide a fixing for a screw to assist in retaining a clip in position, particularly where the clip is at a free end as described above.

The section may be formed as a one-piece plastics moulding.

In accordance with a second aspect of the present invention there is provided a finished roof end having a capping section fitted around tiles projecting at said end, wherein said section has a side wall, opposed top and bottom walls extending transversely to the side wall, the bottom wall being fixed beneath the tiles on to roof battens and the top wall fitting on top of the tiles, and a downwardly projecting wall beneath the bottom wall.

The second aspect of the invention may incorporate any or all of the features of the first aspect of the invention as appropriate.

With regard to the abovementioned clip this may be generally of like cross-section to the capping section although slightly larger so that the said engagement with a capping section end can be effected by fitting the clip over and around such end.

Thus, and in accordance with a further aspect of the present invention there is provided a clip engageable with capping sections particularly for use in the aforesaid capping system, said clip being generally C-shaped and having a side wall, top and bottom opposed walls extending transversely to the side wall, a downwardly projecting wall beneath said bottom wall, and an intermediate wall or ridge extending transversely to said side, top and bottom walls and located centrally of said downwardly projecting wall.

Preferably also there is an inwardly projecting wall at the bottom end of said downwardly projecting wall and this is connected to said intermediate wall or ridge.

The intermediate wall may be provided with a screw hole for fixing purposes.

The bottom wall of the clip may be shortened so as to terminate level with the tile ends and may be shaped to define a drainage groove or channel corresponding with the aforesaid drainage groove or channel of the capping sections.

The intermediate wall may terminate at its top end level with or below the upper extremity of the said bottom wall.

With the abovementioned capping system, when used with a gabled roof end, an apex member may be provided for covering adjacent capping section ends disposed at an angle to each other at the apex of the roof. This apex member may be shaped so that the capping sections can fit against and behind same, and latches or the like may be provided for engagement with the capping sections.

The invention will now be described further by way of example only and with reference to the accompanying drawings in which: Figure 1 is a diagrammatic partially exploded perspective view showing a capping section and two joining clips of a capping system in accordance with one embodiment of the invention; Figure 2 is a perspective view of an apex joining member of the capping system; Figure 3 is a diagrammatic perspective view showing the capping section in position on a gabled roof end; Figure 4 shows the roof end with the capping system installed; Figure 5 is a front elevation of an alternative form of apex joining member; Figure 6 is a sectional view of the member of Figure 5; Figure 7 is a sectional view showing a modified form of capping section engaged with a modified form of joining clip; and Figure 8 is a perspective view of the modified joining clip.

With reference to Figures 3 and 4 a gabled roof end has tiles 1, which are flat, slate tiles nailed to roof battens 2 in conventional manner. At the gable ends the tiles project slightly beyond the adjacent building walls 3 and, as shown, the projecting tile ends are finished off with a capping system which comprises capping sections 4 which are cut to length and joined end to end at each side of the roof with joining clips 5. At the roof apex adjacent ends of capping sections are covered with an apex member 22. The free ends of the outermost capping sections are finished off with further joining clips 5.

With reference to Figures 1 and 3, each capping section 4 is a one-piece plastics moulding generally of C-section having an upright side wall 6, a downwardly inclined top wall 7, a perpendicular bottom wall 8, a downwardly projecting upright wall 9 beneath the bottom wall 8, and a terminal wall 10 projecting perpendicularly inwardly from the bottom end of the wall 9.

A drainage groove 11 is defined in the bottom wall 8 adjacent the side wall 6. The wall 9 is inset relative to the side wall 6 and is level with the inner side of the groove 11. An elongate tubular member 12 runs along the inner side of the wall 9.

As shown in Figure 1, the joining clips 5 are of generally similar section to the capping sections and have a side wall 13, top wall 14, bottom wail 15, downwardly projecting wall 16, terminal wall 17 and drainage groove 18. However, the clip 5 is slightly larger in section than the capping section 4, the bottom wall 15 terminates at the inner side of the groove 18, the tubular member 12 is omitted, and there is an intermediate wall 19 perpendicular and fixed to the walls 16, 17, 18 centrally thereof. Also the terminal free edges of the walls 14, 17 are inturned.

In use, after cutting two capping sections 4 to length (as required) these are joined end to end with a joining clip 5 in the following manner.

First, the section ends are provided with short longitudinal cuts or slots 20 (Figure 1) immediately beneath the bottom walls 8. The ends are then inserted into the clip 5 (as shown at the right of Figure 1) until they abut against the wail 19, the bottom wall 15 of the clip 5 fitting in the slot 20.

As shown in Figure 3, the capping sections 4 fit in position with the bottom wall 8 on top of the tile battens 2 immediately beneath and in contact with the tiles 1. The inner side of the groove 11 abuts the batten ends and the terminal wall 10 rests against the building wall 3. The bottom wall 8 is nailed or screwed to the battens 2 and if desired pre-drilled holes may be provided in the wall 8 for this purpose.

The top wall 7 rests firmly on top of the tiles 1.

Any water which enters beneath this can run away along the drainage groove 11.

The joining clips 5 at the free ends of the capping sections 4 fit over such ends in like manner to the intermediate clips 5 but are fixed in position, as shown in Figure 1, by screws 21 passed through holes 21a in the walls 19 and engaging the tubular members 12.

As shown in Figure 2, the apex member 22 has an arcuate outer wall 23 which is stepped to define two surfaces 24, 25 on which the bottom wall 8 and terminal wall 10 of the adjacent capping sections 4 can rest. There is also a central strengthening web 26. On each side of this web 26 there is a rotatably mounted catch member 27. These catch membrs 27 can be pivoted to engage behind the side walls 6 of the capping sections 4 and thereby hold the apex member 22 in position.

The resulting installed capping system is particularly robust and attractive.

It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiment which are described by way of example only.

Thus, for example, accompanying Figures 5 and 6 show respectively a front elevation and a sectional view of an alternative form of apex member 30. The capping sections 4 are clamped in position by a bracket 31. The member 30 has an arcuate top wall 32 which fits over a conventional arcuate ridge tile 33 and is sealed in position with a mastic bead 34. Instead of the arcuate top wall 32 it is possible to provide an angular or shaped top wall for use with correspondingly shaped ridge tiles.

Figures 7 and 8 show a modified capping section and clip. The capping section is as shown in Figure 1 (and like numerals are used for like parts) except that the tubular member 12 is omitted and the bottom wall 8 has a stepped peripheral part 40 provided with regularly spaced elongate slots 41 to receive screws or other fixing devices for attachment to the battens. The joining clip is as shown in Figure 1 except that the intermediate wall 19 is omitted and instead a rubber or resilient plastics strip 42 is bonded to the walls 16, 17 up to the groove 18 and the inturned edge of the wall 17 thereby to define a central abutment ridge.

This ridge 42 acts as an abutment to limit insertion of the clip into the slots 20 cut in the ends of the capping sections. Alternatively or additionally the limit on insertion may be achieved by the lengths of the slots (as also may be the case with the arrangement of Figure 1).

With the arrangement of Figures 7 and 8, end pieces may be provided for finishing off the free ends of the capping sections. These end pieces may be identical with the clip of Figure 8 except that the strip 42 is omitted, an integral end wall is provided at one end of the clip structure and a clamp screw is screwed through the centre of the wall 15 for engagement with the capping section.
