Description

REAR RECEIVER APPARATUS This invention relates to rear receiver apparatus.

This apparatus has particular reference to rear receiver apparatus suitable for use in the construction of domestic patios and the like and for illustrative purposes reference will be had to this application. However, this invention may find use in other applications such as lean-to structures generally.

In general, where roof additions are made to structures such as to provide covering for patios, the roof material is generally affixed to an existing wall or fascia by means of a rear receiver, which generally comprises a channel member supporting the roofing material at the fascia or wall end.

The roofing material of choice is profiled roofing sheet material, the profiling providing the relatively thin sheet with stiffness suitable for roofing over battens or joists. Extruded alloy rear receivers are relatively rigid for their weight and generally comprise an elongate C-channel section adapted to be affixed to the fascia.

15 Whatever the material of the rear receiver, the affixed receiver is adapted to receive the roofing sheet edge into the open face of the C-channel.

The roofing material may be fixed to the rear receiver by fixings penetrating the roofing material and the lower supporting web of the C-channel receiver section.

These fixings are unsightly and tend to create leakage points.

The present invention aims to substantially alleviate at least one of the above disadvantages and to provide rear receiver apparatus and roofing methods which will

be reliable and efficient in use. Other objects and advantages of this invention will hereinafter become apparent.

With the foregoing and other objects in view, this invention in one aspect resides broadly in rear receiver apparatus including:a roofing member support portion having an elongate recess formed therein adapted to receive fixing means for securing a roofing member thereto; and an elongate leakage trough adapted to engage said elongate recess beneath said fixings.

The rear receiver apparatus may comprise an integrally formed or fabricated rear receiver body portion. The body portion may be formed by any suitable means including continuous roll formed or extruded metal section. Whilst the body member may be roll formed in steel or aluminium, or cast or formed in plastics or the like, it may comprise an aluminium alloy extrusion to provide the body member. The receiver section may be configured having a mounting portion adapted to be secured to a fascia or the like and from which the roofing member support portion extends.

The mounting portion may comprise for example an integrally formed continuous web portion of the rear receiver apparatus or alternatively may comprise a separable :mounting bracket or the like.

.oo.oi 15 The mounting of the mounting portion to a fascia or the like is preferably in weatherproof fashion and may take any suitable form. For example the mounting portion may be configured with a bonding surface capable of being adhered to the fascia or the like with or without additional fixings. However, the use of sealants or adhesives renders the apparatus difficult to remove for maintenance or replacement, and depends for its sealing integrity on the skill of the installer. Accordingly it may be that the rear portion be adapted to make weatherproof connection with the fascia or *the like by means of sealing members adapted to be interposed therebetween. The sealing members may provide the weatherproof seal as a consequence of the act of fixing the mounting portion to the fascia or the like.

3 The preferred extruded aluminium alloy rear receiver members may comprise a mounting portion including one or more longitudinal channel portions adapted to receive one or more corresponding sealing members. The sealing members may comprise a resilient materials rugged enough to survive the installation and the environment whilst being sealably effective in use. For example, the sealing member may comprise a stabilized natural rubber or synthetic rubber elongate member adapted to engage the aforementioned channels in the rear portion and adapted to be compressed by fixing means passing through the mounting portion and into the fascia or the like.

Advantageously, the inner surface of the mounting portion is provided with indicia providing an indication of the preferred site for such fixings. For example, there may be provided marked centres or the like, although it is preferred that there be provided a V-groove or the like disposed substantially along the centreline of the mounting portion to provide both a line for the fixings and a start for the installer's 15 drill.

The roofing member support portion may comprise a flange extending out from the mounting portion, and may include a substantially flat bearing surface upon which the roofing material may bear. The bearing surface may be substantially perpendicular to the mounting portion, although it is envisaged that the flange portion 20 may be inclined to the mounting portion accommodating any selected pitch of the roof portion to be supported thereby. Additionally the supporting portion may be profiled to accord to a selected roofing material profile.

Preferably, the roofing member support portion is formed as an integral part of an extruded aluminium body portion including a mounting portion and wherein there 4 is provided an elongate drain portion disposed between said support portion and mounting portion.

The elongate recess may take any suitable form. For example, the recess may, in the case of the preferred aluminium extrusion, comprise a generally dove-tail profile formed in the support portion. By this means, the dovetail section may be used to selectively secure an insert comprising the elongate leakage trough, either by endwise insertion in the case of stiff inserts, or by tool assisted or manual deformation in the case of sufficiently deformable inserts. For example, the elongate leakage trough may comprise a resilient, substantially lenticular-sectioned insert for the dove-tail section recess, defining on its inner surface in use a curved trough be which means any leakage through the fixings may be conveyed to the ends of the trough.

The recess in the support portion may be provided with indicia providing the :installer with the line of the preferred fixing location to the sheet roofing material. If 15 desired the region of the fixing may be provided with additional sealing means adapted to substantially prevent leakage through the fixings. For example, the fixing @9*o may be of a self sealing nature such as grommetted PK or other self tapping fixings.

*The preferred sealing means adapted to engage said roofing member may be replaced or complemented by a drain means disposed between the sealing 20 means and the roofing material support portion mounting means. These features in combination with the elongate trough covering the fixings at the elongate recess provides means whereby rain and run off are kept from the covered area. The drain means may comprise any suitable means of entrapping casual leakage past the sheet edge and may at least in part be determined as to form by the sealing means selected. The sealing means may for example comprise a longitudinally disposed bead of a curable or settable sealing material adapted to be disposed between the support member for the roofing material. However, it is preferred that the sealing means comprise a deformable sealing member associated with the support member and adapted in use to at least partially conform to the sheet profile. Preferably, the sealing member comprises a longitudinal resilient sealing member adapted to sealingly engage the support member and adapted to be engaged by the undersurface of the sheet material in use, the lands of the sheet material compressing the sealing member in sealing engagement, the portions of the sealing member between the lands being resiliently upstanding into the spaces beneath the upwardly directed ridges in the sheet material.

Preferably, the sealing member comprises a longitudinal seal member of section including a mounting portion for sealing engagement with the support member and an tapered upstanding sealing portion. Preferably, the tapered upstanding sealing portion is inclined toward the drain means such as casual water from the drain means may be directed back by the sealing portion.

The drain means preferably comprises a longitudinal drain or drains formed with or in the receiver assembly in the region of the junction of the mounting portion and the support member. In the case of the preferred extruded aluminium receiver o:09 assembly, the drain means may constitute an integrally extruded drain which may 20 also function as a stiffener for the receiver assembly. The drain means preferably drains to one or both ends of the receiver assembly, although it is also envisaged that the drain means may be provided with one or more spouting means adapted to convey drainage to a selected outlet or outlets such as a storm water drain.

The roofing member support portion may comprise one of a pair of such flanges provided on the preferred extrusion such that the apparatus is reversible in use. However, it is preferred that the roofing member support portion comprise the lower of a pair of opposed flanges adapted to receive the sheet edge therebetween, the upper of the flanges being adapted to engage and retain baffle means disposed in the valleys of the sheet profile in use and adapted to keep bulk runoff and debris out of the interior of the receiver assembly.

The roofing material may engage compressible sealing means disposed in the rear receiver assembly and adapted to engage the sheet edge. The edge sealing means may comprise material resistant to being cut by the roofing material edge in compression. For example, the edge sealing means may comprise a sealing member which is of a relatively tough resilient material and wherein the deformability and hence sealability of the member is provided by the physical form thereof.

The edge sealing member may comprise a sealing face adapted to substantially cover the cut profile of the roof material and being integrally formed with a plurality of compressible structures of the same material. For example, the edge sealing member may comprise a substantially continuous extrusion of resilient or elastomeric material having said sealing face and having extruded therein a plurality V09. of parallel tubular compressible portions adapted to bear on the mounting portion.

0 The receiver body member may be configured to receive the edges of the 0%o° ooo* edge sealing member such that the edge sealing member is substantially supported o. 20 thereby and preferably sealed thereto in use. For example, the edge sealing o• 0 member may be bonded to the mounting portion of the receiver body member.

o o Alternatively, the rear receiver body member may be provided with opposed channel means adapted to receive opposed upper and lower edges of the edge sealing member in substantially sealed relation thereto.

0 In order that this invention may be more readily understood and put into practical effect, reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention and wherein: FIG. 1 is a cross section through receiver apparatus in accordance with the present invention; FIG. 2 is a cross section through the receiver apparatus of FIG. 1 in use; FIG. 3 is a perspective view of the apparatus of FIG. 1 in use; FIG. 4 is a perspective view of the apparatus of FIG. 1; and FIG. 5 is a partial end view of the apparatus of FIGS. 1 to 4.

In the embodiments illustrated in Figs 1 to 5, there is provided rear receiver apparatus comprising an aluminium extruded section 40 including a mounting portion 41 having an upper seal retaining channel 42 adapted to retain an upper fascia seal 43, and a lower seal retaining channel 44 adapted to receive a lower fascia seal The upper 43 and lower 45 fascia seals each comprise a compressible elastomeric material adapted to provide sealing engagement of the mounting portion 41 with a fascia or other substrate 46.

oooee mounting portion 41 is adapted to be secured to the fascia or the like 46 by means of a fixing screw 50 or the like, the fixing 50 being adapted to urge the mounting portion 41 towards the fascia 46 or the like such that the upper and lower °20 fascia seals 43, 45 make sealing engagement with the fascia 46 or the like.

A support portion 51 extruded integrally with the mounting portion 41 is adapted to support roofing material 52. The support portion 51 is provided with a longitudinal seal retaining channel 53 adapted to receive a resilient sealing member S54. Between the seal retaining channel 53 and the mounting portion 41, the support 54. Between the seal retaining channel 53 and the mounting portion 41, the support portion 51 and the mounting portion 41 form an integral drain 55 disposed below the level of the roofing material 52.

Outboard of the resilient sealing member 54 the support portion 51 is provided with a fixing recess 56 having a fixing positioning groove 57 adapted to provide an effective drill starter and positioner for the insertion of fixings 60 adapted to retain the sheet material 52 to the support portion 51. The section of the fixing recess 56 is configured to retain a resilient, lenticular section trough forming member 61 adapted to receive any weeping past the fixing 60 and convey such weeping as does pass to the ends of the assembly. The resilience of the trough forming member 61 enables the member to be deformed for insertion in the fixing groove, the resilient recovery of the member causing the member to be retained in the groove.

An upper flange 62 is formed integrally with the support portion 51 and is provided with an upper sealing member retaining channel 63 adapted to retain an upper sealing member 64. The upper sealing member is adapted to sealingly engage upper portions of the roofing material 52.

SThe upper and lower resilient sealing members 54, 64 are adapted to be °loo° compressed by the tops of the ridges and bottoms of the troughs of the roofing ;!"material 52 respectively, and thereby form a compression seal therewith. However, the resilience of the sealing members 54, 64 is such that between the compressed 20 portions of the sealing members, the sealing members are upstanding to form a partial dam.

The outboard edge of the upper flange 62 is adapted to receive press-on plastic baffle members 65 adapted to conform to the shape of the valleys in the sheet material 52.

In use the extrusion 40 is offered up with its mounting portion 41 adjacent to the fascia 46 in the position of installation whereupon the fixings 41 are tightened down to compress the upper and lower fascia seals 43, 45. The roofing material 52 is inserted between the support portion 51and the upper flange 62 and pushed in towards the mounting portion whereby the upper 64 and lower 54 resilient sealing members are passed by the sheet edge. Appropriate holes are drilled through the support portion 51 at the fixing's positioning groove 57 and thence through the roofing material 52 to permit the installation of fixings 60, whereafter the trough forming member 61 is installed. The baffle members 65 are then clipped in position in the valleys in the sheet material 52 by engagement with the outboard edge of the upper flange 62.

Apparatus in accordance with this embodiment has the advantages of not requiring skilled labour for its installation, and providing that any leakage past the fixings does not weep into the space covered by the roofing material.

It will of course be realized that while the above has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as defined in the claims appended hereto.
