• the door leaf 1 itself is composed of bending material, preferably made of woven polyester monofilament.
• the door leaf 1 there is made one window openin 3.
• a window element 11 which include means for compensating tensile and/or press load caused of bending of the window element and so for making possible that the window element 11 will convert curved, i.e. becomes longer or shorter.
• the converting of the window element curved is accomplished by forming the shape of window element's 11 cross-section profile tooth wave-like, which wave-like corrugations extend cross the whole window element crosswise in relation to the winding direction.
• wave-like cross-section profile it is naturally possible to use other wave form or corrugations, for example cross-section profile having a shape of a sine wave.
• Material of the window element 11 can be chosen quite freely, however, it is advantageous to use a plate or leaf of clear polycarbonate, which owns an excellent resistance against wheater changes and shocks, and which will not break into shivers. According to the invention scratching and rubbing of th window element 11 against the woven fabric, when the roller door is winded around the roller tube, is prevented by moulding means extending crosswise in relation to the winding direction.
• the window element 11 is fastened to the door leaf 1 from its upper and under edge by rigid fastening moulding 12 extending parallel in relation to the geometric axis of rolle tube so, that, tightening organs 14, for example rivets, extend through the fastening moulding 12, through the edge part of the window element 11 adapted thereunder and through the woven fabric of the roller door.
• tightening organs 14 for example rivets
• the function of the invention it is of course not significant what kind of tightening means are used for accomplishing a moulding fastening for the window element 11 suitable are for example fastening solutions by means of screws, rivets or the correspondings.
• the height of the fastening mouldings is larger than the height of corrugations of the window element 11, whereby the fastening mouldings prevent rubbing of the window element against the woven fabric of the roller door.
• the window element 11 is fastened to the door leaf 1 from its upper and under edges by rigid fastening mouldings 12* extending parellel in relation to the geometric axis of the roller tube so, that tightening organs 14, for example rivets extend through the fastening moulding 12', through the edge part of the window element 11 adapted thereunde and through the woven fabric of the door leaf.
• tightening organs 14, for example rivets extend through the fastening moulding 12', through the edge part of the window element 11 adapted thereunde and through the woven fabric of the door leaf.
• the height of the fastening mouldings is smaller than the height of corrugations in the window element 11, whereby for preventing th rubbing of the window element 11 against the woven fabric of the door leaf extra mouldings 15 are fastened, for example by means of gluing, into the recessions of the corrugations of the window element, the height of the extra mouldings being larger than the height of the corrugations in the window element.
• fastening mouldings 12 in accordance with the presentation relating to the figure 2.
• the window element 11 is fastened to the door leaf from its upper and under edge by rigid fastening mouldings 12' parallel in respect to the geometric axi of the roller tube so, that the tightening organs 14, for exampl rivets, extend through the fastening moulding 12', through the edge part of the window element 11 adapted thereunder and throug the woven fabric of the door leaf.
• Conserning the function of th invention it is of course not significant what kind of tightenin means are used for accomplishing a moulding fastening for the window element 11 suitable are for example fastening solutions b means of screws, rivets or corresponding.
• the height of the extra mouldings is smaller than the height of the corrugations of the window element 11.
• the rubbing of the window element against the woven fabric of the door leaf is prevented by fastening heave mouldings 16 onto both the fastenin mouldings 12' and the extra mouldings 15'.
• the crosswise mouldin composing of two-layer mouldings accomplished in this way prevents the rubbing of the window element 11 against the woven fabric when the roller leaf is winded as illustrated in the figure 4.
• the edges of the window element 11 extend, preferably 2...20 cm most preferably about 10 cm, over the boarder of the window opening, and that the window element 11 is fastened to the door leaf 1 at least from its uppe and lower edges parallel in respect to the geometric axis of the roller tube. Whereby in practise a sufficient stiffness is achieved even by means of the corrugated zone or zones of the window element 11.
