Abstract

A solar shading system comprising a blade or louvre element 50 and blade mounting support (60 Fig. 1), each mounting support having a first and second clip 62 (68 Fig 5) for securing the blade in position. Preferably the clips have receptive channels or grooves 54 56 on the blade surface. The first clip 54 62 secures the blade to the support member for pivotal movement about a longitudinal axis of the blade from a first position to a second position, in the second position the second clip means 56, 68 retain the blade in a fixed angular position. The mounting support may have two extending support arms 64 66, preferably on the opposite end of the mounting support is a shoulder (80 Fig 2) for fixing to a support beam 90 via a plurality of fixings (82 Fig 2). The support means may also comprise a cantilever arm that is secured within the beam 90. The system is used for mounting solar shades to the exterior of buildings to prevent unwanted sunlight or solar heating of the building.

Description

245650^
Blade Elements
This invention relates a blade element and more particularly to a blade element suitable for mounting in a spaced array of like elements for screening, solar shading 6 and for other applications.
One important application is to provide one or more arrays of such elements to provide solar shading for buildings. Solar radiation may account for substantial heat input to a building transmitted through glazing and through windows and curtain walling. Glass surfaces may transmit significant heat to the building interior in 12 certain circumstances. Excess heat requires removal to maintain a desired internal temperature with consequent higher energy costs and a more adverse environmental impact.
To mitigate such problems it is known to provide solar shading by mounting louvre systems in the form of horizontal arrays of louvre blades to curtain walling structures 18 and it is an object of this invention to provide improved louvre blade apparatus suitable for solar shading for curtain walling, for windows and for other structures and for other applications.
Our co-pending Application No. of even date describes a support bracket suitable for attachment to a curtain wall mullion of a known kind as therein 24 described. One object of the present invention is to provide improved louvre blade apparatus suitable for use with for example the support brackets described in our copending application, which description is incorporated herein by reference. The improved louvre apparatus of the present invention is not limited to solar shading applications for curtain walling systems but may be more generally applicable to other structures including doors or windows and more generally to other applications apart 30 from solar shading requiring an array of blade like elements which may be referred to herein as louvres, louvre blades or by analogous terms.
1
In this specification the terms 'outer' 'outwardly' and 'inner' and 'inwardly' and analogous terms if used have the same meaning as in our co-pending application referred to above unless the context otherwise requires.
36
The terms 'blade element' 'louvre' and similar terms as used in this specification mean a rigid or resilient element which is relatively long in relation to its width and which is relatively thin at the longitudinal edges in relation to its width, which may have flat or curved surfaces, may be hollow or be constructed of one or more parts shells or skins and which may be formed by extrusion from suitable plastics or 42 aluminium alloy. Any reference herein to a surface of a blade element is intended to be a reference to the obverse or reverse surfaces as the context may require, in either case bounded by the length and the width of the blade element, the edge surfaces being disregarded unless otherwise specifically identified.
At the present time solar control louvres for external use on buildings are either 48 clipped or screwed onto a supporting structure mounted on the outside of the building. Known clipping systems suffer from the disadvantage that louvres may become loose and rattle or become detached during windy weather. Screwing each louvre in place to a supporting structure is a time consuming and costly process in proportion to area to be shaded.
54 In one aspect this invention consists of a blade element having first and second clip means provided on one surface, the first clip means being adapted to retain pivot means provided on a blade mounting means to permit the blade element to captively rotate about a longitudinal axis into a second position in which the second clip means may be locked to a support arm forming part of the blade mounting means.
60
The invention will now be described by way of example only with reference to the accompanying drawings in which:
Figure 1 is cross section view of a blade element and blade mounting means prior to mounting of the blade element for external solar shading of a building.
66
2
Figure 2 is a similar view to Figure 1 in which the blade element is engaged for captive rotation on a pivot arm extending from a blade mounting bracket.
Figure 3 is a similar view to Figure 2 in which the blade element has been rotated about the pivot arm shown in Figure 2 to engage a locking clip with a support arm 72 extending from a blade mounting bracket
Figure 4 is a perspective view of an end portion of the blade element illustrated in Figure 3 showing pin locking means for securing the second clip means provided on the blade element to a blade mounting arm mounted on a support beam
78 Figure 5 is a magnified view of the encircled clip details shown in Figure 3
Referring firstly to Figure 1, there is shown in cross section a hollow extruded aluminium alloy louvre blade element 50 having opposed convex obverse and reverse surfaces having an internal screw port 52. Blade mounting means in the form of a mounting bracket 60 is provided with extending support arms 64 and 66 connected 84 together by a web 67 for rigidity. The obverse surface of the blade element presenting towards the mounting bracket 60 is formed with first clip means in the form of a centrally disposed extruded channel formation 54 which is formed to receive the complimentarily formed end portion 62 of support bracket arm 64 as more clearly shown in Figure 5.
90 The formations 54 and 62 are so shaped as to permit the insertion of the male formation 62 into the channel 54 when the parts are oriented as shown in Figure 2.
Rotation of the blade element 50 about the end portion 62, constituting pivot means locks the element to support arm 64. Further rotation of the blade element 50 to a second position as shown in Figure 3 causes the second clip means in the form of an 96 extruded channel 56 firstly to receive and subsequently to engage with the end portion of a support arm 66 provided with engagement means in the form of nib 68.
Referring to Figures 3 ,4 and 5 it will be seen that blade 50 is secured to the end portions of support arms 64 and 66 of the blade mounting bracket 60 by means of a
3
pin 70 driven along the channel 56 to force the nib 68 of arm 66 into locking 102 engagement with a complimentary formation provided in the channel section 56,
preventing rotation of the blade and locking the blade element 50 at an end portion with respect to the supporting arms of the mounting bracket 60. The opposite end portion of blade element 50, not shown, is supported in the same way.
The mounting bracket 60 has a shoulder 80 opposite the support arms fixed to a 108 support beam 90 by means of fixings 82. The support beam 90 is provided with a hollow section 92 adapted to receive and be secured to the cantilever arm of the bracket described in our co-pending patent application No of even date herewith.
