Definitions

• This invention relates to a ventilated ridge of a sloping glazed roof, such as a roof of a conservatory or sunlounge, and in which the ridge may serve as the means of attachment of a "lean to" structure, or as the apex of a two sided roof.
• the present invention is primarily concerned with framing made of UPVC, which can be readily extruded in profile form which enables the components employed to complete the glazing of panels (usually glass or clear plastics sheets) into the framing to be assembled on site by simple but reliable snap-fit engagement.
• the present invention therefore seeks to provide, by simple means, for ventilation of the room space using a novel venting arrangement which is reliable and inexpensive.
• a sloping roof structure for a sunlounge or conservatory and which comprises: a roof frame; glazed panels for assembly with the frame to form the roof structure; and, a ridge for mounting along an upper generally horizontal side of the roof frame, said ridge having a mounting slot extending along its length and facing the glazing panels so as to receive and to hold the upper edges of the panels; in which: at least part of the mounting slot includes means to support the underside of the upper edge of at least one glazing panel with a ventilation slot defined with said underside to exhaust warm air in the region adjacent to the glazing panel; a venting chamber is defined within the structure of the ridge to communicate with said ventilation slot; and, an outlet is provided in the wall of the ridge which communicates with said venting chamber and which faces outwardly to discharge warm air from the chamber.
• a roof structure according to the invention therefore provides in simple manner for reliable exhaust of warm air via the ridge from a room underlying the roof structure e.g. a sunlounge or conservatory, while still providing satisfactory support for the upper edges of the glazing panels .
• warm air generated in the room by the action of sunlight will rise and collect in a layer below the underside of the panels, and by virtue of the slope of the roof structure, this warm air will be directed in a direction towards the ventilation slot.
• the warm air then passes to the venting chamber and is discharged to atmosphere via the outlet and therefore this sets up a current of warm air movement which promotes ingress of cooler air into the room as well as discharging the warmer air.
• the ridge is preferably hollow and built-up from extruded plastics material sections, or particularly UPVC, and may be of a form suitable for securement to a supporting wall so that a "lean to" structure is provided, or it may form the apex of a roof structure which is of inverted V-shape as seen in end view to form a conservatory, in which case glazing panels on either side of the ridge will have their upper edges supported by the ridge. Either one, or both sides of the ridge may have a mounting slot and ventilation slot as desired.
• the support means in the mounting slot is arranged to support the upper edge of more than one glazing panel with a ventilation slot defined with the underside of the panel.
• each glazing panel in the mounting slot may be provided by means of a side wall which is shaped so as to receive usual glazing bars as a direct fit therewith, with the space between adjacent glazing bars forming the ventilation slots.
• the discharge outlet may be formed by a side wall section arranged above the upper face of each panel.
• the side wall section is L-shaped, and has means on its underside for carrying a seal to engage the upper surface of the respective panel.
• a closure flap is provided to cover the entrance to the ventilation slot, and which can be remotely operated between open and closed positions as required.
• a gauze or other mesh panel is provided over the discharge outlet, to prevent access to the venting chamber, from externally of the roof structure, of insects, leaves etc.
• the sloping roof structure may be provided with a ventilated support at its lower or "eaves" end.
• Figure 1 is a schematic side view, partly in section, of the ridge of a sloping roof structure according to the invention, which is intended to form part of a lean-to sunlounge or conservatory;
• Figure 2 is a view, similar to Figure 1 , of the apex of an inverted V-shaped roof structure of a sunlounge or conservatory;
• Figure 3 is a perspective illustration of a lean-to conservatory which may be provided with a roof structure according to the invention
• Figure 4 is a perspective illustration of a so-called 'Victorian type" conservatory provided with a roof structure according to the invention.
• Figure 5 is a schematic side view of a ventilated support at the lower or "eaves" end of the sloping roof structure.
• Figure 1 shows a ridge structure of a sloping roof structure for a sunlounge or conservatory
• Figure 1 shows a ridge structure of a sloping roof forming part of a lean-to sunlounge or conservatory
• Figure 2 shows a ridge of an inverted V-shaped roof structure of a so-called Georgia conserveatory.
• Figure 3 shows perspective view of the lean-to conservatory to which the arrangement of Figure 1 may be applied
• Figure 4 shows a structure of 'Victorian" conservatory to which the structure of Figure 2 may be applied.
• a sloping roof structure which comprises a rectangular roof frame, glazing panels e.g. single or double glazed glass or rigid plastics panels, for assembly with the roof frame to form the roof structure, and a ridge for mounting along an upper generally horizontal side of the roof frame.
• the ridge has a mounting slot extending along its length and facing the glazing panels so as to receive and hold the upper edge of the panels.
• the mounting slot includes means to support the underside of the upper edge of at least one of the panels with a ventilation slot defined with such underside to exhaust warm air in the region adjacent the glazing panels, a venting chamber defined within the structure of the ridge to communicate with the ventilation slot, and an outlet provided in the wall of the ridge which communicates with the venting chamber and which faces outwardly to discharge warm air from the chamber to atmosphere.
• a glazing sheet 1 has its upper edge mounted within a mounting slot in the side face of a ridge 7 which is built-up from extruded UPVC sections, and the mounting of the upper edge of panel 1 is such that a venting slot 5 is defined between its underside and a supporting wall of the ridge.
• a lower trim fitting 6 is snap-fitted to the underside of ridge 7.
• a venting chamber 2 is defined within the ridge, and which communicates with the ventilation slot 5, and warm air which migrates upwardly to engage the underside of panel 1 is then directed upwardly along the underside of the panel towards the ventilation slot and then enters the venting chamber 2.
• a through-flow path for warm air is provided, which passes through ventilation slot 5 into venting chamber 2, and then discharges to atmosphere via an outlet fitting 3 having an outlet which is covered by a flyscreen or other mesh 4.
• the ventilation slot 5 is therefore located at the highest interior region of the conservatory, which ensures that the airflow is unimpeded.
• Ridge 7 in Figure 1 is designed so as to be able to be secured to a supporting wall 20 so that the conservatory is of a lean-to structure
• Figure 2 shows a ridge 7a which forms part of a double sided sloping roof structure.
• the ridge 7a shown in Figure 2 has ventilation slots 5 provided for each sloping roof structure, and this is a preferred arrangement, although only a single sided arrangement or ventilation slot may be provided if required.
• Each ventilation slot 5 is defined between glazing bars 8 (see Figure 3) which are located, at their upper ends, between jaws 9 and 10 ( Figure 2) which define both the mounting slot for upper edges of the glazing panels, and also define the ventilation slot 5 with the underside of the panels. Therefore warm air within the conservatory can be exhausted via the ventilation slots defined on the underside of the glazing panels 1 between the glazing bars 8.
• Each ventilation slot can be permanently open to provide permanent ventilation. Alternatively, openable cover flaps may be provided, which can be remotely operated in order to open or close access to the ventilation slots.
• intermittent supports are provided in the space between the panels and the support of the glazing bars 8. This can prevent any undesirable sagging of the panels at the upper edges.
• each glazing panel preferably takes the form of an L-shape section 11 (also fitted in the mounting slot in the side face of the ridge 7), on the underside of which a usual seal 12 is provided to engage the upper surface of the panel 1.
• a ventilated support structure may be provided at the lower or eaves end of the sloping roof structure as shown schematically in Figure 5.
• FIG. 5 shows the upper end of a supporting wall structure of the lower end of a sloping roof, and this shows the roof glazing 50 simply supported on an upstanding flange 51 of an aluminium ring beam 52 provided at the upper end of conservatory side framework 53.
• the flange 51 defines a channel in which a ventilated support 54 is received, which supports the load of the roof glazing 50, but also defines one or more ventilation apertures which allows external air to be drawn inwardly and to flow upwardly along the underside of the sloping roof for ventilation purposes.
• the ventilation may be closed by a sliding or other closure arrangement on the inner face thereof, for operation by an occupant of the room when desired.
• any suitable "hold-down” clamping structure may be provided in order to hold down the roof glazing on the flange 51.
• This may comprise conventional clamping arrangements provided at each end of flange 51 to clamp the roof glazing and hold it down.
