1 Claim. (Cl. 98-88) This invention relates to a combined mounting memher and drainage channel. It deals more particularly with a combined mounting member and drainage channel for use with ventilators adapted to be inserted into an opening in a wall or a sloping roof of a building, such ventilators being hereinafter referred to as ventilators of the kind described.

It is an object of the present invention to provide a combined mounting and drainage channel which will secure the ventilator in position in the wall or roof of a building without allowing the entry of rain water into the building.

It is a further object of the invention to provide a mounting member to enable a stock size ventilator to be mounted in a water tight manner in a range of opening sizes.

It is astilI further object of the invention to provide an improved drainage means for ventilators.

With the above and other objects in view, the invention will be hereinafter more particularly described and the arrangement of the mounting member and ventilator will be shown in the accompanying drawings and pointed out in the claim.

Now referring to the drawings:

Fig. 2 is a section of the line IIII of Fig. 1,

Fig. 3 is a section on the line IIIIII of Fig. 1 to an enlarged scale, and showing the position of the ventilator in the aperture in the wall of a building.

Fig. 4 is a section through the bellows and winding gear shown in Fig. 3,

Fig. 5 is a detail view,

Fig. 6 is a side sectional elevation of a combined fixing, mounting member and drainage channel. constructed in accordance with the present invention, Fig- 7 is a fragmentary perspective view taken from underneath in the direction of the arrows on the line VII'-VII. of Fig. l and showing part of the ventilator to which the combined mounting member and drainage channel has been attached.

According to the embodiment illustrated in Figs. 1 to 5 of the drawings the ventilator comprises a box like frame or housing 2 forming the ventilator opening, the housing 2 having a flat fascia frame 4 at the front or interior of the building longitudinal sides 6 normal to the fascia frame 4 are provided with flanges 8 for the whole-of their length, said flanges being at right angles to the sides 6 and parallel to the fascia frame 4. The fascia frame 4 cornprises a pair of spaced parallel combined mounting and drainage channel members 76 and a pair of spaced parallel transverse upper and lower walls 29 and 32 respectively and described below in greater detail. The attachment of channel members 76 to the upper and lower walls is effected by any of the well known means e.g. bolts and rivets and is considered to be a matter of design only. Secured to or formed integral with these flanges 8 are upstanding narrow ribs 10. Said ribs 10 in the form shown are formed of a single thickness of sheet metal folded back and turned up at right anglesto the flanges 8- and are pierced by holes 12 at intervals along their length to receive and journal the hinge rods 14 running across the frame 2. Ten louvers 16 are hingedly mounted on rods 14 inserted in the holes 12. Said louvers 16 are each formed from a single sheet of metal longer than it is wide and approximately shaped so that it can be formed by a pressing operation. The longitudinal edge of the louver sheet adjacent which the hinge is to be formed is bent over to form a double thickness projection 18 the corners of which are cut away for Vsth inches on each side of the louver so that the projection 18 clears the flanges 8 by about /eth inches on each side. The longitudinal free edge of the double thickness projection 18 is bent up into a circular section beading 20 adapted to receive the hinge rod 14, said beading 20 being approximately %th inch from the double edge of the projection 18 and running parallel toit. The other longitudinal edge of the louver is shaped into' an inverted serni circular trough or channel 22 which faces in the opposite direction to the beading 20. Each of the transverse edges of the louver is formed with a slightly tapered trough 24 running from the hinge beading 20 to beyond the trough 22, said troughs 24 facing in the same direction as the trough 22 and having their larger diameters adjacent the trough 22. Where each tapered trough 24 meets the trough 22 a semi-circular piece- 26' is cutaway from it to allow one trough to communicate with the other.

Said louvers are mounted: on the hinge rods 14 in the narrow ribs '10 with their hinged edges lowermost. A louver bracket 28 is riveted or otherwise secured to each louver 16- near the trough 22. Each said louver bracket 28 is provided with a hole at its free end adapted for loose connection with a linking control bar 30. Said con trol bar 30' is formed from a single sheet of metal bent to a narrow U and drilled through at spaced intervals by holes 31', the free ends of the brackets 28 being riveted in the holes 31 in the U in such a way that the control bar 30 canbe moved relative to the said brackets 28.

The transverse lower wall 32 is formed as a trough and provided with a drain aperture 90. Furthermore, lower wall 32 is provided with an extension 34 which extends below the ends of the ribs 10 and carries a U shaped shield 36 bolted to it by a bracket 38. The upper end of the U shaped shield 36 is embraced by a bracket 40 bolted to the flat fascia frame 4. The shield 36 is square in cross section and forms a cover for a chain hereinafter described. A worm screw 41 inside the casing 42 is worked by a control knob 44 to drive the said chain into the shield 36 when the knob is turned. The stiff section of the chain is protected by a bellows 46 and is secured to an end member 48' pivotally mounted on the control bar 30 by the securing screw 52'. A two armed spring 50 is mounted on the securing screw 52, the end of said spring 50 being turned over the end member 48 and the bar 30 so that they always exert a downwards pressure on the end member 48.

The ventilator is adapted to be recessed into thewall or sloping roof of the building in which it is to be incorporated and to be secured therein in a manner to be hereinafter described with the flat frame 4' flush with the interior surface of the wall and the hinges of the louvers lowermost. When the louvers are open they are substantially horizontal and the chain is fully retracted into the shield 36. As the control knob is turned the chain feeds out into the bellows 46 and pushes the louvers up to the closed position. In the closed position the troughs 22 and 24 on each louver engage partly around the hinging beads 20, the upstanding portions 10 of the flanges 8 and the upper ends of the troughs 24 of the adjacent louvers immediately above them. In this way any rain which finds its way into the hinges of the louvers when they are closed will be carried across into the troughs 24 and will run down them past the extension 34 into the trough formed in the bottom wall 32 from which it will drain away through the drain aperture 90 provided above the downwardly outwardly sloping ledge of the aperture in the wall of the building as shown in Fig. 3.

Referring now to Figs. 4 and 5 the said chain is of the type in which the links 56 are provided with abutments 58 and with teeth 60 forming a rack on one side of the chain. Thus in one direction the chain can only be slightly arched and will then form a stiff rod which can be used to transmit a longitudinal thrust whilst in the other direction the chain can be freely flexed. The rack formed by the teeth 60 on the one side is adapted to cooperate with the worm screw 41 which thus forms a driving means for imparting a thrust to said chain. Since the two-armed spring 50 is always urging the end member downwardly the chain links 56 emerging from the casing 42 will always be arranged in a slightly arched manner to form a stiff rod.

Now referring to Figs. 6 and 7 there is shown a portion of the side of the frame of the ventilator 2 having a side wall 6 formed with an inwardly turned flange 8 defining the ventilator opening to the exterior of the building and a short outwardly directed flange 72. The side wall 6 of the frame 2 is provided with a re-entrant joggle 74, the

depth of which is equal to the thickness of the metal of which the hereinafter described flange is formed.v The combined mounting and drainage channel member 76 is made of sheet metal and comprises a short first flange 78 adapted to fit the joggle 74 in the side wall 6 of the side frame 2, whilst being supported on the flange 72, and

secured to the wall 6 by rivets 80; an outwardly extending portion 82 at right angles to the first flange 78 and parallel to the flange 72, said portion 82 having the dimension A of a standard width i.e. 1" or 2" or 3" as required, to fit a window frame of the selected range of apertures in which the ventilator may be fitted; an upstanding swage 34 of triangular cross section provided in said outwardly extending portion 82; a back turned channel extending the length of the inside of the ventilator, and communicating with drain aperture 90 through lower wall 32 above the sloping ledge of the aperture in the wall of the building so that water in the ventilator drains out thereof onto said sloping ledge and thence to the exterior face of the building.

The said mounting member 76 is of the same length as the side frame and the double thickness portion has an overall width A depending on the width between the glazing bars or other opening defining elements of the building. The joint between the first flange 76 and the side frame 2 at the joggle 74 does not necessarily need to be water-tight since even if water does penetrate the joint it merely flows into the drainage channel and out onto the sloping ledge provided at the aperture in the wall of the building.

The joggle 74 provided in the side frame wall 70 allows the outside wall 70 of the ventilator side to present an unbroken appearance and this to a certain extent prevents water collecting there.

With this type of combined mounting member and drainage channel as above described I have found that ventilators can be made in standard units and interchangable mounting members fitted to any unit according to the design of the building and the supports for the mounting members, and. in this way the setting up of special tools is avoided.

Having thus described one embodiment of the invention, it is to be understood that the mounting member and drainage channel is susceptible of modifications such as may be obvious to anyone skilled in the art and that the embodiment disclosed is descriptive and not to be construed as limiting the scope of the invention.

Again it is to be understood that the materials from which the mounting member may be manufactured and herein defined in the specification and claim as metal clearly indicates materials which are capable of supporting the weight of the ventilator and of withstanding the weather, such as plastics and plastic covered metals and even thin wood.

What is claimed is:

In a ventilator, a box like metal frame having a louver opening and comprising spaced substantially parallel side walls and a rectangular fascia frame secured to said side walls, said fascia frame comprising substantially parallel upper and lower walls and substantially coplanar and spaced combined mounting and drainage channel mem'- bers secured to said upper and lower walls, said upper and lower walls being secured to said side walls, said upper and lower walls extending substantially perpendicular to said channel members and to said side walls, said side walls each being provided along one side thereof with inwardly disposed and opposite flanges perpendicular thereto and along the other side thereof with outwardly disposed flanges perpendicular to said sidewalls, a rib secured to each of said inwardly disposed flanges, a plurality of louver members within said louver opening and .extending between said side walls and rotatably carried by said ribs thereby providing angular adjustment of said louver members within said louver opening, said lower wall being provided with a first extension extending below the ends of said ribs to catch water raining on to said louver members and with a second extension adjacent said channel members to form a trough in the bottom of said ventilator, said lower wall being provided with a drainage aperture for draining water collected in the trough, said channel members being of sheet metal and attached to each of said outwardly disposed flanges, each of said channel members comprising a first flange in abutment with the adjacent of said outwardly disposed flanges, an outwardly directed reversely bent wall portion at right angle to said first flange and merging therewith at one end thereof, a back turned wall portion extending from the other end of said outwardly directed reverselybent wall portion and directed inwardly beyond said first flange to define a second flange projecting within said side wall, said first and second flanges and said outwardly directed reversely bent wall portion defining a drainage channel communicating with said drainage aperture.
