    Description


    [0001] The subject of the invention is a collar that connects a roof penetrating building construction of any type with the sub-roofing structure, e.g. the roof window frame with the external diaphragm sealing off the deeper layers of the sub-roofing structure from atmospheric effects.

    [0002] A collar for leak-proof connection of roof penetrating building structures with the external weather-protecting diaphragm and with the roof battens set on the diaphragm is known from the patent application WO 99/02799, which discloses a collar according to the preamble of claim 1. The collar consists of four elements connected together having an inner edge fastened to the external surface of the element of the building structure which penetrates the roof and an external edge grasping the roof battens and resting on the diaphragm between the battens.

    [0003] The elements of the collar are made of sections of a flexible and water resistant material. These elements which are to be set crosswise on the battens are longer than the building structure to which they are to be connected and are doubled down, e.g. in form of folds, in order to adjust the length of inner edge to the perimeter of the building structure for which the collar is intended. Upon setting the inner edge of the collar along the external perimeter of the building structure, the folds on the side of the external edge are spread out, so as to include the battens laying above the external diaphragm, and adjoin the diaphragm between the battens.

    [0004] The side elements of the collar bent into folds are secured by the manufacturer against spreading or unfolding by gluing two paper strips of which one is glued along the inner edge of collar element, in this way stabilizing the length of the inner edge of the collar, while the second paper strip is glued at some distance from the external edge, securing the folds from spreading at the time of shipment and installing the collar. Upon connecting the inner edge of the collar to the building structure, the second paper strip is to be ripped so as to enable the folds to spread out freely on the side of the external perimeter of the collar. of claim 1

    [0005] The inner edge of the collar, secured by the glued paper strip, is not adequately strong. Damaging the paper strip on shipment or assembly and spreading of the folds makes the collar unsuitable and requires repeated, manual arranging of the folds when connecting the collar with the building structure set on the roof. Making a collar with folding side elements or ones bent in another way to adjust their length to the length of building structure elements with which they are to be connected, requires additional time and manual work, as well as using expensive folding devices.

    [0006] The object of the invention is to provide a collar that seals the connection of the building structure penetrating the roof with the sub-roofing structure of the roof, which is reliable at the time of assembly and adequately fulfills its purpose, the inner edge of the collar having a constant length, equal to the external perimeter of the building structure, while its external edge enables adherence of the external boundary of the collar to the sub-roofing structure of various height, which collar can be easily manufactured and not requiring any expensive folding device.

    [0007] The collar, according to the invention as defined in claim 1, is made of any flexible waterproof material and has the form of a frame, which surrounds the structure resting on the roof. The collar has an inner edge with constant length, fitting the given building structure, the edge enabling connection of the collar with the external perimeter of the structure. The collar consists of an upper, lower and two side elements, connected to form a closed perimeter. Upper and lower elements are flat strips and parallel to the roof battens. Two side elements which are at right angles to the battens are strips of a curved surface, preferably a ruled one, which in ready to be mounted and in mounted collar state are limited at the inner side of the collar by a straight collar inner edge, and at the outer side by a space curve. The collar, upon connecting its inner edge with the external perimeter of the structure resting on the roof, spreads freely on the external surface of the sub-roofing structure of the roof, enclosing the roof battens to which it is fastened and adheres to the external surface of the diaphragm between the battens.

    [0008] The upper and lower elements of the collar laid in parallel to the roof battens consist usually of known flat strips of various width, limited on their length by parallel sides of various length but having a common axis of symmetry which define inner and outer edges of said upper and lower elements, while the shorter sides consist of three segments, the two external ones being at right angles to the longitudinal, parallel sides and connected by an oblique segment. In mounted collar state, after connection of the collar elements together, external segments of upper and lower elements, which constitute a right angle with the shorter side adhere to the building structure penetrating the roof.

    [0009] The side elements of the collar laying under a right angle relatively to the battens are strips which before connection of said side elements with the upper and lower the elements have the shape of a segment of a ring, consisting of one or several parts connected together lengthwise, while each part is limited on the two opposing sides by arcs, preferably concentric ones. The radiuses of the arcs are adjusted so, that the length of the inner edge of that collar element is equal to the length of the side of the structure with which the element is to be connected along a straight line, and the external edge of that collar side element in form of curved surface strips can freely adhere to the external diaphragm and to the upper and side surfaces of the battens laid on the diaphragm. The length of the external edge depends of the thickness of the roof counter battens and battens, but is suffices usually that the external edge of that side element is by 40 % longer than the collar inner edge.

    [0010] All elements of the collar are permanently connected together by known means along parts of their shorter sides, i.e. along oblique segments and segments constituting a right angle with the shorter side in mounted collar state.

    [0011] The elements of the collar made according the invention, which are laid at an angle against the battens can constitute a supplement to the assembly collar known from the utility model PL-Y1-57604, consisting of U-shaped upper and lower elements. The side elements made according to the invention shall be slid by one end under the upper element of the assembly collar, and the opposite end being laid on the lower element of the assembly collar.

    [0012] The collar according to the invention is shown as an example in the drawings, of which Fig. 1 depicts the collar elements before connecting them together into a closed perimeter, Fig. 2 shows the collar laid on the roof window frame and adhering to the sub-roofing structure, and Fig. 3 presents the form of the collar assumed by it when set on the window frame.

    [0013] The collar 1, that connects the window frame 2 of the roof window with the external diaphragm 3 of the sub-roofing structure, consists of the upper 4, lower 5 and two side 6 elements connected together to form a closed perimeter.

    [0014] The upper element 4 and the lower element 5, which are parallel to the battens 7, are flat strips of various width limited lengthwise by parallel sides of various length but having a common symmetry axis, which define inner and outer edges of said upper and lower elements, while their shorter sides consist each of three segments, respectively a, b, and c in the element 4, and a, b, and c' in the element 5, the outermost segments a, as well as c and c', being orthogonal to the longitudinal, parallel sides and are connected by an oblique segment b. The segment a constitutes the height of the grip adhering to the window frame 2 in mounted collar state, and the segment c is longer than the segment c'.

    [0015] The side elements 6 of the collar 1, lays at right angles to the battens 7, are strips, which before connection with upper and lower elements have the shape of segment of a ring, the length of internal arc 8 is equal to the length of the side element of the window frame 2, and the external arc 9 is by 40 % longer. The shorter sides of the elements 6 consist of the segments a and b, identical with the segments a and b of elements 4 and 5. In mounted collar state the elements 4, 5 and 6 are permanently connected together along the segments a and b, forming a closed perimeter.

    [0016] Upon connecting the inner edge of the collar 1 with the external perimeter of the window frame 2 along a straight line, the internal arc 8 of the side element 6 becomes a straight line 8a and the surface of the side element 6 automatically becomes corrugated so, that its external arc 9 forms a space curve 9a, which enables adhering of the external edge of the collar 1 to the upper and side surfaces of the battens 7 and to the external diaphragm 3 between the battens 7.
