The present invention relates to improvements in roof structures and components, especially for conservatories. Other aspects of the invention are concerned with structural features of conservatories.
Hipped Roof Features
A first aspect of the present invention is concerned with roof ridge assemblies, especially for conservatories of the hipped type in which panel supporting bars radiate from one end of a ridge structure, the supporting bars being connected between the ridge end and an eaves beam and the ridge end being provided with a cap overlying the end portions of the supporting bars.
In known arrangements, to prevent ingress of rainwater etc beneath the cap, flexible foamed material is pushed into the gap between the cap and the underlying roofing in a somewhat haphazard and unreliable manner.
This aspect of the present invention seeks to provide, inter alia, a more reliable sealing arrangement for the ridge end construction.
The present invention resides in a ridge end assembly for a hipped roof in which panel-supporting elongate members of the hipped roof are connected to the ridge end by connectors which are provided with means for locating lengths of sealing material between the panels supported, in use, by the panel supporting members and an overlying ridge end cap.
The lengths of sealing material may be in the form of strips located with one edge contacting the panels and the opposite edge contacting or in close proximity to the underside of the cap.
The lengths of sealing material may be located at a position at or immediately adjacent a lower edge of the ridge end cap so as to intercept rainwater at the opening between the panels and the ridge end cap.
The invention also resides in a connector for use in connecting panel-supporting bars to the ridge end of a hipped roof, the connector being provided with a formation for coupling to a mounting element associated with the ridge end and locating means for positioning strips of sealing material between the panels and an overlying ridge end cap.
The strips may have sealing contact at least with the panels and, optionally, with the ridge end cap so as to achieve weatherproofing to a substantial extent, especially with respect to ingress of rainwater.
The locating means may form part of the connectors or, alternatively, may be provided on separate components which are adapted to be fitted to the connectors.
The locating means may be formed by spaced flanges which extend substantially transversely to the panel-supporting members, the flanges being arranged so that a section of the sealing material can be inserted in and retained in position by the flanges.
At least one of the flanges may be provided with an upstanding flexible sealing gasket for co-operation with the overlying ridge end cap.
The connectors may be provided with drainage channels for directing any water penetrating beneath the cap to channels provided on the supporting bars.
The drainage channels may be provided directly on the connectors or, alternatively, on separate components adapted to be fitted to the connectors, which components will usually be the same components as referred to above but the possibility of different components being used is not excluded.
The drainage channels may be formed by lateral extensions which may be arranged to contact the undersides of the panels in the proximity of the ridge end.
For the avoidance of doubt, it is contemplated that the provision of a connector with a drainage channel or channels as disclosed herein may constitute a separate aspect or aspects of the invention which are not necessarily limited to use in combination with the locating means.
The extensions may be provided with gaskets for sealing contact with the undersides of the panels.
The flanges and/or the extensions may be integrally formed with the connectors.
Each connector may be provided with a hook-shaped formation for connection to an arcuate mounting element associated with the ridge end.
Enhanced Security Roof Structure Features
The subject matter of the present application includes an improved roof structure; in particular, one which affords greater security against thieves making entry through the roof of a conservatory or the like by removing one or more panels.
This may be embodied in a roof structure comprising a ridge, an eaves beam, spaced apart glazing bars extending between the ridge and the eaves beam and roofing panels supported by the glazing bars, characterised in that to provide security against removal of the roof panels: each glazing bar comprises an inner elongate member which has at least one shoulder providing support for the inner face of an edge of a roofing panel and at least one outer elongate member for co-operation with the inner member and, in use, overlies an outer face of the roofing panel edge, the inner and outer elongate members being so arranged that lifting of the panels is prevented by (a) the members being coupled together by fastening means operable from the inner member side of the glazing bar and/or (b) means associated with the inner member for obstructing lifting of the panel independently of the outer member(s) in such a way as to maintain the panel captive against lifting from the inner member after the outer member has been removed; and the lower edge of at least one the panels is provided with an end fitting including a portion overlying one end of the roofing panel to prevent that end of the panel being lifted.
In this manner, it is possible to locate the panels between the inner and outer members and because the fastening means is not operable or accessible from the side of the assembly on which the outer member is located, greater security is afforded against break-in to a conservatory or the like by removal of a roof panel or panels. This is in contrast with the glazing bar assembly of British Patent Application No. 2347963 where break-in can simply effected easily by levering the capping from the bar and then removing one or more roofing panels.
The end fitting serves to prevent access to the lower end of the roofing panel and, in conjunction with the arrangement of the glazing bars affords enhanced security against break-in because, usually the other end of the roofing panel or panels extend to a ridge structure part of which overlies that end of the roofing panel(s) resulting, by virtue of the present invention, in both ends of the panel being trapped at the ridge and eaves structures thereby further obstructing any attempt to remove the panel(s).
A glazing bar suitable for use in the above-defined enhanced security roof structure may have one or more of the following features in any combination where the context admits:
A glazing bar having any one or more of the foregoing features a.–o. is considered to constitute an invention in its own right and the applicant reserves the right to seek protection thereof without limitation to other features disclosed in this specification.
The glazing bars may be arranged to support the panels on each side thereof and obstructing means may be associated with each side of the glazing bar.
This may be embodied in a glazing bar assembly comprising an inner elongate member which has at least one shoulder for providing support for the inner face of an edge of a roofing panel and at least one outer elongate member which co-operates with the inner member and, in use, overlies an outer face of the roofing panel edge, means being associated with the inner member for obstructing lifting of the panel independently of the outer member(s) in such a way as to maintain the panel captive against lifting from the inner member after the outer member has been removed.
Features which may pertain to the obstructing means include one or more of the following, which features may, where the context admits, be employed in any combination and also in any combination with any one or more of features a.–o. above.
A glazing bar having any one or more of features a.–h. aforesaid is considered to constitute another aspect of the invention and the applicant reserves the right to seek protection thereof without limitation to other features disclosed herein.
The enhanced security roof structure may have the following additional features which may be present in combination with one or more of the glazing bar features a.–o. above and/or one or more of features a to h of the obstructing means as specified above:
The end fitting is to be understood to constitute an invention in its own right and the applicant reserves the right to seek protection for the end fitting independently of the glazing bar features which prevent lifting of the panels. Usually the other end of the roofing panel or panels extend to a ridge structure part of which overlies that end of the roofing panel(s) and it will be seen that the end fittings in accordance with the above aspects of present invention will afford security against break-in even if the glazing bars are designed as disclosed in British Patent Application No. 2347963 because both ends of the panel remain trapped at the ridge and eaves structures thereby obstructing any attempt to remove the panel(s).
In terms of the end fitting, the invention may reside in a roofing structure comprising an eaves structure, glazing bars supported on the eaves structure, one or more roofing panels supported by the glazing bars and an end fitting including a portion overlying one end of the roofing panel, the end fitting being connected to the eaves structure through male and female connector parts which are arranged to be coupled together by push insertion of the male part into the female part in a direction transverse to the eaves structure in such a way that the male part is captive against withdrawal in the opposite direction to insertion.
In a modification, the aspect of the invention relating to end fittings may reside in a roofing structure comprising an eaves structure, glazing bars supported on the eaves structure, one or more roofing panels supported by the glazing bars and an end fitting including a portion overlying one end of the roofing panel, the end fitting and eaves structure being coupled at one location by a fulcrum arrangement so that the end fitting can be mounted in different tilted attitudes with respect to the eaves structure and the end fitting being adapted to be coupled to the eaves structure internally of the outer face of the latter and at a location spaced from the fulcrum arrangement.
In another expression, this aspect of the invention may reside in an end fitting comprising a channel for location at the eaves structure of the roofing structure and arranged to receive the forward end of a roofing panel, a laterally projecting leg which serves as a fulcrum to allow tilting or rocking of the end fitting relative to the eaves structure so as to accommodate the pitch of the roof, and a section extending rearwardly of the leg to provide a limb which extends laterally in the same general direction as the leg whereby the end fitting may be engaged with the eaves structure at a location on the inboard side of the eaves structure.
Eaves Beam and Cill/Framework Features
Another aspect of the present invention relates to the construction of conservatories of the type in which glazed window frames are provided between an eaves beam and a cill, the eaves beam and the cill being in the form of extruded profiles, e.g. of a metal such as aluminium or aluminium alloy or of a plastics material.
One of the problems associated with the fabrication of such conservatories lies in the cutting of the extruded profiles to form corner joints. This is generally done by mitring of adjacent sections of the extruded profile. To ensure accuracy, the cutting is often done off-site (e.g at factory premises) and the previously mitred profiles are then transported to the erection site.
This aspect of e present invention seeks to provide a conservatory design which eliminates the need for the production of mitred joints between sections of the eaves beam and/or cill profiles.
This aspect of the invention consists in a conservatory framework comprising an eaves structure from which the roof is supported and a cill for mounting one or more window frames located below the eaves structure, at least one corner and/or in-line joint in the eaves structure being formed by a separate connector which interconnects adjacent sections of the eaves structure and comprises a block having side faces from which projections extend for reception within the profile of the eaves structure.
This aspect of the invention also consists in a conservatory framework comprising an eaves structure from which the roof is supported and a cill for mounting one or more window frames located below the eaves structure, at least one corner and/or in-line joint in the eaves structure and the cill being formed by a separate connector which interconnects adjacent sections of the eaves structure and/or the cill, the eaves connector comprising a block having side faces from which projections extend for reception within the profile of the eaves structure.
In this way, the need to mitre the profiled sections is eliminated. Instead, each profiled section may be cut substantially at right angles relative to the length of the section and the connector may be configured to interconnect the profile sections at a predetermined angle relative to each other.
The connector may be arranged to interfit with each profiled section in such a way that the two components are telescopically interconnected, e.g. so that one component inserts into the other. For example, the connector may have two angularly related projections each for receiving or reception in an end of one of the profiled sections.
A framework in accordance with this aspect invention may have any one or more of the following features:
This aspect of the invention is applicable for example to glazed roofs of the type comprising panels, e.g. of glass or a plastics material such as polycarbonate or polyvinyl chloride, supported between glazing bars which may be produced as extruded profiles. The glazing bars are coupled at one end to an eaves beam and extend upwardly to a fixing location at the opposite end, usually a ridge structure of the roof.
To allow for the pitch of the roof, it is known to connect the lower ends of the glazing bars to the eaves beams in such a way that they can be tilted to accommodate the desired roof pitch. In one known arrangement as disclosed in British Patent Application No. 2347963, the lower ends of the glazing bars are coupled to the eaves beam by a bolt having a head which is pivotally located in a channel forming part of the eaves beam.
This aspect of the present invention seeks to provide an improved means for coupling the glazing bars to an eaves beam which affords greater flexibility during on-site installation.
The glazing bar mounting shoe constitutes an invention in its own right and the applicant reserves the right to seek protection for the same both in combination with other features disclosed herein, including the eaves and cill features as disclosed above, and also independently of such other features. The shoe serves to intergage with and locate one end of a glazing bar, the shoe being adapted to be tiltably mounted on an eaves structure and the arrangement being such that the glazing bar is insertable endwise into the shoe, the shoe including an end stop which limits the extent to which the bar is insertable into the shoe. The shoe may have one or more of the following features in any combination admitted by the context:
In another expression of this aspect of the invention, the eaves structure connector may comprise a block for interposition between adjacent eaves beam sections and having means for interengagement with adjacent eaves beam sections, means for tiltably mounting a glazing bar and means for registry with a load-transmitting member for transferring the weight of a roof supported from the eaves structure to said member.
Such an eaves structure connector may be used in combination with a glazing bar-mounting shoe tiltably engageable with the connector.
Also, this aspect of the invention may reside in a corner, in-line or end connector for use with an eaves beam structure or a cill, the connector being adapted to interfit with a non-mitred end of an extruded eaves beam or cill profile (which may of closed or open configuration) so as extend beyond the end of the profile and provide means for location of load-transmitting components associated with the eaves beam and/or cill.
Such a connector may have two projections which are in-line or angularly related and serve to interconnect adjaent eaves beam or cill sections.
The connector may comprise an end connector having a single projection for coupling with the end of an eaves beam or cill profile.
In a framework as defined above, the eaves structure and/or cill may terminate in an end connector as defined in the preceding paragraph.
Coupling of Ridge Cap to Ridge Structure
This aspect of the invention relates to roof structures, especially for conservatories and is particularly concerned with the coupling of a ridge cap to a ridge structure.
In a known roof ridge structure for a glazed roof (see UK Patent No. 2284836), a ridge cap is secured to the ridge structure by rigid bolts which have heads engaging in a channel on the underside of the ridge cap and which pass through openings in the roof structure to allow the cap to be secured place by nuts.
This arrangement requires the ridge cap to be located in place at the apex of the ridge structure and the bolts registered with the cap and the ridge structure after the roofing panels have been put in place, making it necessary for the installer to get on to the roof to position the ridge cap accurately and register the bolts with the cap and with apertures in the ridge structure to allow the nuts to be connected to the bolts from a location below the ridge structure.
This aspect of the present invention seeks to provide a more flexible coupling of the ridge cap to the ridge structure which does not necessarily require the installer to get on to the roof in order to complete fitting of the ridge cap.
This aspect of the present invention resides in a ridge assembly for a roof comprises a ridge structure, a ridge cap for fitting atop the ridge structure, the ridge cap having a channel at its underside, and at least one fastener having an enlarged part for reception and retention in the channel, the fastener comprising a flexible tie by means of which the cap can be secured from beneath the ridge structure by a locking member co-operating with the tie.
The tie may have one or more of the following features in any combination where the context admits:
The various aspects of the invention will now be described by way of example only with reference to the accompanying drawings, in which:

The bars 10 extend between the ridge structure 12 and an eaves beam (not shown) and roofing panels 18 (see
Each bar 10 comprises an inner member 20 and an outer member 22 either of both of which may be manufactured as aluminium extrusions. The panels 18, in use, are trapped between the inner and outer members 20, 22 and extend from the eaves beam to a point proximate the ridge end. The inner member 20 is generally T-shaped comprising a central portion 24 and a cross-piece 26 which has upwardly directed flanges 28 forming shoulders on which the inner faces at the panel edges of the panels 18 can seat. The construction and design of the bars 10 may be as described in detail in other embodiments disclosed herein. For present purposes, a notable feature of the inner member 20 is the provision of channels 27 formed by the cross-piece 26 and flanges 28, which channels serve as drainage channels in circumstances where ingress of water might occur despite the use of seals associated with the inner and outer members 20, 22.
The mounting element 16 in the illustrated embodiment is in the form of a generally semi-circular ring 30 (a D-shaped ring) which is secured to the ridge structure 12 by plate 32. Each bar 10 is linked to the D-ring 30 by the connectors 14, one of which is illustrated in detail in
The connector further includes an intermediate section 46 and a forward section 48 which is angularly related to the rearward section 40 and terminates in a downwardly directed hook-like formation 50 for engagement with the D-ring 30 in the manner illustrated in
The intermediate section 42 is provided with location means comprising spaced flanges 56, 58 projecting laterally of each side face of the connector and also upwardly relative to the top of the connector. When the connector section 40 is fully inserted into the bar 10, the end of the bar abuts against the flange 56. The flanges 56, 58 define channels on each side of the connector for the location of strips 60 of sealing material, e.g. a resilient foam material so that the strips can seat on the panels 18 and at least substantially bridge the gap between the upper faces of the panels 18 and the underside of an overlying, external cap 62 (shown in broken outline in
The lower edge of the strips 60 are intended to make sealing contact with the panels. If desired, the seal may be enhanced by the application of a mastic or other sealing material which can be applied as a bead along the junction between the strips 60 and the roof panels. The upper edges of the strips 60 may also make sealing contact with the underside of the cap 62 although this is not essential as a small gap may be tolerated athtis point because the main source of rainwater ingress will tend to be by way of water driven up the panels faces by the wind and this will be intercepted at the junction between the strips and the panels.
To avoid having to specially shape the end edges of strips 60 and thereby simplify fabrication, the flanges 56 may be overmoulded with a flexible gasket 66, the upper edge of which is designed to contact against the underside of the cap 62 and deform downwardly when the cap is located in place to provide sealing at that location. In this way, the relatively small gaps above the connectors 14 are effectively sealed by the gaskets 66. The downward deflection of the gaskets 66 may be in the forward direction, ie. towards the edge 63 of the cap 62.
It will be noted that the strips 60 are located at the forward opening of the gap between the panels and the cap 62 thereby intercepting
As well as serving to connect the bars 10 to the ridge structure 12 and also locate the sealing strips 60, the connectors 14 additionally provide a drainage facility if and when needed. To this end, each connector is provided on each side with a lateral wing-shaped extension 70 on which the roofing panel edges seat in the proximity of the ridge end. The extensions form channels 72 which, when the connector is fitted to a supporting bar 10 merge, and desirably overlap to some extent, with the channels 27 associated with the cross-piece 26 of the inner member 20. The extensions 70 are formed with overmoulded gaskets 72 for sealing contact with the underside of the panels 18. Any water that might penetrate through the gap between the roofing panels 18 and the connectors 14 is collected by the channels 72 and, by gravity, is directed into the channels 27 and along the length of the bars to drainage points at the lower ends of the bars.
The flanges 56, 58 and/or the extensions 70 may be integrally formed with the connectors 14. Alternatively, these components may be formed separately from the connector as part of a component or components adapted to fitted to the connector.
Security Features of Roof Structure
Referring to
Each glazing bar 10 comprises an inner member 14 and an outer member 16 either of both of which may be manufactured as aluminium extrusions. As used herein, “inner” and “outer” refer to the location of the components relative to the roofing structure. The inner member 14 is generally T-shaped comprising a central portion 18 and a cross-piece 20 which has upwardly directed flanges 22 forming shoulders 24 on which the inner faces at the panel edges 26 of the panels 12 can seat. The panels 12 may seat directly on the shoulders 24 or indirectly via interposed seals (not shown). The central portion 18 comprises a deep channel formed by two upstanding spaced apart walls 30.
The cross-piece 20 may in use be concealed on the internal side of the glazing bar in known fashion by a cladding section or sections of plastics material, aluminium or wood for example, the cladding section(s) being attachable to the inner member. The cladding section(s) may be provided with the seals on which the panels seat.
The outer member 16 is generally V-shaped having downwardly directed legs 32 which extend from each side of a central section 34. The legs 32 together with the flanges 22 form openings which receive the edge portions 26 of the panels. The legs 32 may contact the outer face of the panels directly or indirectly via unshown seals (not shown). A main pair of walls 36 extend inwardly from the central section 34 and define a channel which, when the inner and outer members are assembled together as shown, interfits in telescoping fashion with the channel defined by the walls 30. In the illustrated embodiment, the channel associated with the outer member 16 receives the channel-forming walls 30 associated with the inner member 14; however, the arrangement could be reversed.
The central section 34 is also provided with a housing 38 formed by spaced walls 40 having inwardly directed lips 42 which serve to trap the head(s) of one or more bolts 44. The bolt heads may be introduced through open ends of housing 38 at the ends of the outer member 16. The bolts 44 are of sufficient length to extend inwardly through the channel defined by walls 30 and through and beyond drilled holes in the cross-piece 20 so that the inner and outer members 14, 16 can be coupled together by tightening of a nut 46 threaded on to the inner end of the bolt 44. In this manner, the inner and outer members 14, 16 may be drawn together on opposite sides of the panels 12 to firmly locate the panels and secure good sealing via interposed seals. Usually the inner and outer members will be coupled together by bolt and nut sets 44, 46 at two or more locations along the length of the glazing bar. The seals may co-extruded with the profiles forming inner and outer members 14, 16 or they may be bonded thereto.
It will be observed that, when the roofing structure has been assembled, the fastening means formed by the bolt and nut 44, 46 firmly secure the inner and outer members together and afford effective resistance to the outer member 16 being detached from the inner member 14 merely by levering the outer member upwardly as is readily possible with the plastics connector used in the assembly shown in GB Patent No. 2347963.
In the illustrated embodiment, the bolt head is captive with the outer member 16 while the nut co-operates with the underside of the inner member 14. In a modification, the nut may be captive within the housing 38 and the bolt head may co-operate with the underside of the inner member.
In another modification, the outer member may be provided with an extension corresponding to the housing 38 which projects into close proximity with the cross-piece so that the inner and outer members may be coupled together by a fastener such as a self-tapping screw 60 which engages in, for instance, a suitable aperture provided in the lower end of the extension. This embodiment is illustrated in
In a further modification, instead of the outer member being a single component as illustrated in the drawing, it may consist of two components extending laterally and downwardly from opposite sides of the central stem portion 18, in which case the arrangement may be such that the inner member is coupled to one or both of the outer members by a coupling arrangement which is not accessible from the external side of the roofing structure.
Referring to
The outer member 116 is generally V-shaped having downwardly directed legs 132 which extend from each side of a central section 134. The legs 132 together with the flanges 122 form openings which receive the side edge portions of the panels. The legs 132 may contact the outer face of the panels via seals 135. The outer member is releasably coupled to the inner member by reception of inward exension 137 which may be bifurcated within a channel 139 at the free end of the stem portion 118. The extension 137 may be integral with the outer member or it may be a separately formed components which is secured to the outer member. The channel 139 may be provided with formations such as internal ribs for co-operation with projections on the extension 137 in order to provide resistance to separation of the outer member 116 from the inner member 114.
Thus far, the glazing bar construction is generally similar to that disclosed in British Patent Application No. 2347963. With such an arrangement, it will be seen that once the outer member is removed by levering it away from the inner member, the side edges of the panels are then free thus enabling the panels to be lifted and allowing entry to be gained by an intruder.
In contrast with the glazing bar construction of British Patent Application No. 2347963, the glazing bar forming the embodiments of

The retainers 140 may be assembled to the side edges of each panel 112 prior to placement of the panel on the inner members 114 during construction of the conservatory or like building. The panel plus retainers is positioned on the inner members and the legs 150 of the retainers can be flexed appropriately to allow them to pass over the cross-piece 120 and then brought together secured by the coupling 152. This method of fitting is particularly applicable where the retainers are of an adequately flexible material such as a suitable plastics. An alternative method of assembly involves initially fitting the retainers 40 to the inner member and then registering the panels with the channels 142 at one end of the inner member and sliding the panels into position. Once the panels have been located, the outer members are connected to the inner members by engagement of the extensions 137 with the channels 139.
Each retainer may also co-operate with the outer member if desired in such a way that the outer member is linked to the retainers and hence to the inner member independently of the interconnection afforded by the extension 137 and channel 139. In the embodiment of

As described with reference to the embodiment of
Referring now to
Associated with the lower or forward ends of the panels 210 is an end fitting 214 which may be manufactured as a plastics extrusion or a metal extrusion such as an aluminium or aluminium alloy extrusion. The end fitting 214 has at its forward end a channel 216 having a rearwardly directed open mouth for reception of the forward ends of the panels 210. The channel 216 is defined by a base 218 which closes the open end of the polycarbonate panel, a wall 220 which overlies the marginal edges at the lower ends of the panels 210 and a lower wall 222 which underlies the lower end of the panel. In this manner, the end fitting co-operates with the lower panel edges extending between adjacent glazing bars. The wall 222 may serve as a thermal break in that it prevents direct exposure of the overhanging portions of the inner faces of the panels.
The fitting includes a downwardly directed leg 224 which projects laterally from the wall 222, e.g. at an angle of 90 degrees, for engagement with the top wall of the eaves structure 212 so as to act as a fulcrum about which the fitting can tilt or rock about an axis parallel to the axis of elongation of the end fitting (i.e. perpendicular to the plane of the paper as viewed in
An L-section shaped portion 226 extends rearwardly of the leg 224 and includes a laterally projecting limb 228 which is spaced from and extends downwardly in generally parallel relation with the leg 224 for co-operation with the rear of the eaves structure. The limb 228 is intended to be fastened to the eaves structure so as to locate the end fitting 214. To this end, the limb 228 and the rear of the eaves structure may be drilled to receive a self-tapping screw to firmly secure the end fitting in place. It will be noted that the attachment of the end fitting 214 to the eaves structure 212 is located interiorly and cannot be accessed from the exterior when the roof panels are in place.
To facilitate tilting of the end fitting according to requirements, the limb 28 may be provided with a number of forwardly directed projections 230 for co-operation with a flange 232 projecting rearwardly from the eaves structure. As shown in
Referring now to
The spigot 326 comprises a pair of wing portions 330 projecting to either side of the leg 324. Assembly of the spigot 326 to the socket 328 involves push insertion of the spigot 326 through a slot-shaped opening 332 forming the mouth of the socket 328. To this end, the wing portions 330 have some degree of flexibility such that they close up during insertion through the opening 332 and then spring back or restore to the configuration illustrated once fully inserted into the socket. Although the spigot may be readily inserted into the socket, once the parts have been assembled the spigot is then captive against withdrawal through the opening by virtue of expansion of the wing portions 330 to the illustrated configuration. To ensure that withdrawal is blocked, the marginal edges of the opening 332 may be turned inwardly or provided with inwardly projecting lips or other formations which co-operate with the free ends of the wing portions 330 to trap the spigot. In
In the modification of
In the embodiment of
Although the arrangement can be such that the spigot cannot be withdrawn from the socket in a direction tranverse to the longitudinal axis of the eaves structure (at least not without damage to the spigot and/or the socket), it will be appreciated that because the eaves structure is usually an extruded component with the socket extending along the full extent of its length, the end fitting may be uncoupled from the eaves structure by sliding it along the eaves structure to the end of the latter.
In each embodiment, the wall 222 may be provided with spacing elements such as ribs to space the underside of the roof panel from the wall 222 to permit water drainage in the event of water ingress into the channel 216. If desired, the channel, e.g. the wall 222, may be provided with outlet holes to allow drainage of any water into the guttering.
The end fittings in each case will typically be cut to length (from an extruded profile) to correspond with the spacing between adjacent glazing bars, although the possibility of using an end fitting of a length sufficient to span the width of two or more roofing panels is not excluded nor is the possibility of using end fittings which are somewhat narrower than the spacing between adjacent glazing bars.
The ridge structure includes a part which overlies the upper ends of the panels with the consequence that lifting of the upper ends is prevented. If the security afforded by the glazing bars is in some way breached, the use of an end fitting according to the present invention serves to trap the lower end of each panel thereby preventing the lower end of the panel being lifted and a would-be intruder is further hindered by the fact that the fixture of the end fitting is located interiorly and is not therefore accessible without damaging the roofing panel thereby creating noise which could alert others to the intruder's activity.
In a modification of the illustrated embodiments, the end fitting may be provided with a downwardly depending leg located forwardly of the fulcrum and forming a closure or weatherproofing member which covers the gap between the underside of the roofing panels and the forward face of the eaves beam. This is depicted in phantom outline by reference numeral 50 in the embodiment of
Where the end fitting is fabricated as a metal extrusion, it may incorporate a thermal break between the fulcrum and the remainder of the end fitting, e.g. between the leg 224 or 324 and the lower wall 222.
Eaves Beam and Cill/Framework and Glazing Bar Shoe Features
Referring firstly to
In the embodiment illustrated in
Currently the practice is to produce the joints by mitring the adjacent sections of the extruded profiles forming the eaves beam and the cill, which is time consuming and requires a significant degree of accuracy in cutting if well-fitting joints are to be achieved. For this reason, the sections of the extruded profiles are usually cut to size and mitred off-site and then delivered to the construction site. Also, in current designs, the weight of the roof structure is largely transmitted from the eaves beam to the cill and hence to the load-bearing wall 100 through the glazed window frames which are often fabricated from extruded PVC profiles. In accordance with the present invention, mitring of the joints between the adjacent sections of the extruded profiles is eliminated by employing separate connectors which provide the corner joints or in-line joints of the eaves beam and/or the cill and “squaring off” the ends of the extruded profiles by cutting them substantially at right angles to the length of the profile.
One example of a corner connector for the joints E1 in the eaves beam structure is shown in
As shown in
In each of the connector embodiments shown in
Alternatively, instead of a tiltable bolt arrangement, the tiltable connection may be achieved by means of glazing bar-mounting shoes as will described further later. In the case of the corner connectors of
The connector embodiments of
Each connector is provided with a formation which interengages with the load-transmitting members 164. For example, where the load-transmitting members are in the form of posts, the connectors may be provided with recesses 166 (not shown in
Cill corner connectors are illustrated in
The cill connectors as described above interfit with the cill sections by insertion of the ends of the latter within their interiors. However, the possibility of the cill connectors having portions which insert into the ends of the cill sections is not excluded. In this case, the cill connectors may have a central portion which is exposed and substantially flush with the cill sections.
As in the case of the connectors for the eaves structure, each of the cill connectors is adapted for co-operation with the substantially vertical load-transmitting members 164, in particular the bottom ends of the latter, so that the weight of the roof structure is transmitted to the load-bearing wall 100 thereby largely by-passing the window frames. The bottom ends of the members 164 may seat on the top walls of the cill connectors in which case the cill connectors will be provided with means for registry with and location of the bottom ends of the members 164. Alternatively, as illustrated in
The eaves beam connectors and the cill connectors may be produced as plastics mouldings, e.g. polypropylene or nylon, or they may be fabricated from other materials such as aluminium or aluminium alloy.
Reverting now to the mounting of the glazing bars 110,
As shown in
The inner member 24 is T-shaped and comprises a cross-piece 26 and a central stem 28 which terminates at its upper end in a channel 30 by means of which the outer member may be attached to the inner member, e.g. in the manner disclosed in the above mentioned prior British Applications. The cross-piece 26 may be provided with cladding (not shown) to conceal the inner member on the inner side of the roof. Once the outer members have been assembled to the inner members of the glazing bars, the roofing panels are trapped between the inner and outer members in the manner disclosed in the prior British Applications.
In constructing the roof, the glazing bars are coupled at their lower ends to the eaves structure in a tiltable manner to accommodate the pitch of the roof, such coupling being effected by means of glazing bar mounting shoes 10 (see
As shown in
The base of the channel 40 acts as cladding for the lower end portion of the inner member 24, the remaining length being clad by for example plastics cladding extending along the inner face of the glazing bar substantially from the shoe to the ridge. The stop plate 48 as well as limiting the extent to which the glazing bar can be inserted, also serves as an end closure for the glazing bar thereby obviating the need for a separate end closure. If desired, the stop plate 48 may be provided with a projection (not shown) for co-operation with the outer member to prevent the latter being lifted at that point by a would-be intruder attempting to gain access through the roof by removing the roofing panels.
At its underside, the shoe 10 is provided with a downwardly directed projection which terminates in a portion 50 which co-operates with the eaves beam directly or the eaves beam connectors to allow the shoe and hence the glazing bar to tilt in the direction depicted by reference A according to the desired pitch of the roof. For this purpose, the profile of the eaves beam or the eaves beam connectors includes a channel 162 for reception of the portion 50 so as to allow such tilting to occur. In the embodiment of
The bracing plates may in addition to affording reinforcement for the end stop 48 also serve to locate fastening means for securing the shoe to the glazing bar. For example, the bracing plates 54 and the central stem 28 of the inner member 24 may be drilled to receive a bolt to couple the stem to the bracing plates.
In
In
The cill end connector 206 has a configuration which generally matches that of the cill profile and interfits with the end of the cill either with the internal profile or the external profile of the latter. For example, the cill end connector 206 may be dimensioned to receive the cill or it may be shaped to insert into the cill profile. An aperture 208 is provided in the connector 206 for location of the post 204 to allow for load transfer to the wall 100 or to ground level.
In use, the post 204 may be secured by any suitable means to the wall of the house against which the rear end of the conservatory is located. The arrangement may be such that the post 204 transmits the weight of the roof to the wall of the house or the securing arrangment may be such that it transmits the load to the wall 100 or to ground level.
In the foregoing description with reference to the drawings, the eaves beam and the cill have closed profiles, e.g. box-type sections. However, the possibility of their having “open” profiles (i.e. a profile which does not enclose a space on all sides) is not excluded.
The connectors disclosed herein may be used in conjunction with the any one of the arrangements disclosed in the present application.
Coupling of Ridge Cap to Ridge Structure
Referring to the
The cap 16 is secured in place from the interior of the conservatory during the construction process by means of a number of flexible ties 34 which may be made of a suitable plastics material having sufficient strength for the intended purpose. This may be done from beneath the roof, e.g. after roofing panels have been fitted to one side of the ridge. The cap can then be left to rest on that side of the roof while the remaining roof panels are fitted.
Each tie comprises a main shank 36 terminating at its upper end in an enlarged portion 38 for engagement within the channel 22 in the manner illustrated in
The enlarged portion 38 is designed to be contractible in one direction so that it can be push-inserted through the slot 28 and then expand to retain the tie engaged within the channel 22. In the illustrated embodiment, the enlarged portion 38 is generally of arrowhead configuration having wings 50 which project laterally so that they can deflect inwardly as the enlarged portion 38 is pushed through the slot 28. Once the wings are fully within the channel 28, they can return to their unstressed configuration in which the ends of the wings 50 seat on the inner faces of the lips 26 and prevent uncoupling of the ties from the cap.
In use, the ties 34 are coupled in the manner described above to the ridge cap 16 at spaced intervals along the length of the cap and are inserted through apertures in the ridge structure 10 so as to project below the latter. The ties are made sufficiently long that their lower ends can be gripped from below the ridge structure even when the cap is not in position, e.g. when the cap is laid to one side of the peak of the ridge after fitting of the roofing panels at one side of the ridge and before fitting the remaining roof panels. Once the panels have been put in position, the cap can then be moved to the correct location as shown in
The locking member 44 may, if desired, be arranged so that it can be retracted back along the tie towards the lower end of the latter to release the tie. For example, the locking member may have a pawl or pawls adapted to engage the ratchet members and means for moving the pawls to an inoperative state to allow such retraction of the locking member. Alternatively, the ratchet formations may extend over only part of the periphery of the in such a way that the teeth of the locking member coact with the ratchet formations when the locking member is in one orientation but are clear of the ratchet formations to allow retraction when the locking member is in a second orientation. Movement between the two orientations may, for instance, involve rotating the locking member through 90 degrees.
In a modification, instead of the enlarged portion being contractible to allow it to enter the channel 22, it may be dimensioned so that, in one orientation, it will pass through the slot 28 but when turned through 90 degrees, it is then trapped within the channel.
Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance, it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features disclosed herein and/or shown in the drawings whether or not those features are described in relation to the same embodiment or in relation to different embodiments and whether or not particular emphasis has been placed on such feature or features.
