(54) RIDGE COVER ELEMENT
(71) I, OSKAR FLECK, a citizen of the
German Federal Republic, of Industriestrasse 12, 4354 Datteln, German Federal
Republic, do hereby declare the invention for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to a ridge cover element which is intended to be laid in the direction of a roof or like ridge together with other, similar elements in such a manner that parts of the elements overlap.
In order to cover the ridge of a house use is made of so-called ridge caPs of plastics material preferably polyvinylchloride, by which the ridge can be covered and rainproofed without using mortar. Ridge cover elements have been proposed which consist of a cover cap of elongated shape and bent over along one or more edges, or of curved profile. These elements are disposed on the roof ridge in such a manner that they project over the top of the adjoining roof bricks or tiles. They are for example made of a plastics material which has a thickness of from 1 to 3 mm., and which is fastened by nails on a ridge board and covers the latter in a rainproof manner.In addition it has been proposed to form such cover elements from a sealing strip which consists of a flexible carrier and of a compressible sealing body disposed on its lower face and clinging to the upper face of the roof covering plates lying beneath it.
Ridge cover elements, or ridge caps as they are also called, have been used for some years. A particular disadvantage is found to be the fact that the elements are not always easy to align for installation purposes. This is especially the case when a strong wind is blowing and the thin elements are lifted, or when the ridge cap is composed of two identical parts which are so shaped that they overlap on a strip along the board.
Moreover, in the case of the firstmentioned ridge covering the inner side of the cover elements have a matching curved cross-sectional shape. Since the two edges serve as sealing strips it is necessary to keep in stock sealing strips of different types for the various shapes of roof cover platens.
The problem therefore arises of providing ridge cover elements which on the one hand are suitable for numerous roof cover platens, but on the other hand can be installed easily and reliably, without any upward arching of the cover elements through the action of wind occurring.
On the other hand, good adaptation and rainproof laying of the ridge bricks must be possible, these bricks being laid on the ridge covering formed by the ridge cover elements.
According to the present invention there is provided a ridge cover element, wherein the element is in the form of an elongated cover plate which has a curved cross-section and which has side parts which, when the element is in use, extend down over a ridge board and engage over and bear sealingly against the ends nearer the ridge of covering plates or roof tiles, the element being intended to be laid in the direction of the ridge together with other, similar elements in such a manner that parts of the elements overlap; wherein in the region where the element is intended to overlap or be overlapped, the element is formed with a step which extends over the curvature and the height of which corresponds to the thickness of the material of a hip brick; and wherein sealing strips made of an elastic foamed material are disposed beneath the longitudinal edges of the element.
When the ridge cover elements are laid in an overlapping arrangement the steps are retained, so that, at intervals corresponding to the length of the cover element, steps are formed in which two ridge bricks can be inserted and overlapped. The sealing strips adapt themselves to the different surfaces, so that the cover elements can be used for different surfaces.
In order to ensure a good sealing action also in the end-face overlap regions of the ridge tiles, provision is made for the sealing strips of one end face of the element to proJect in the axial direction into the over apregion. Given suitable bevelled cutting to shape, tight joints between elements can be obtained.
Because of the particularly good sealing action of the sealing strips of foamed material it may in addition be necessary for the ventilation of the space below the ridge cover element to be intensified. Ventilation holes can therefore be formed on both sides of the apex of the element and have a relatively large cross-section with an inside cross-sectional area of from 1 to 5 square centimetres.
It should also be emphasised that it is possible not only to make the ridge cover elements so long they they correspond in each case to a ridge brick, but also to give them for example two or three times that length. The speed of laying is increased accordingly.
In order to enable the invention to be more readily understood, reference will now be made to the accompanying drawings which illustrate diagrammatically and by way of example some embodiments thereof, and in which:- Figure 1 is a perspective view of a first embodiment of a ridge cover element,
Figure 2 is a side view of the element shown in Figure 1,
Figure 3 is a front view of a slight modlfication of the element shown in Figure 1,
Figure 4 is a perspective view of a second embodiment of a ridge cover element,
Figure 5 is a front view of the element shown in Figure 4,
Figure 6 is a perspective view showing how the elements shown in Figures 1 to 3 are laid,
Figures 7, 8 and 9 are cross-sections showing three different arrangements of sealing strips,
Figure 10 is a longitudinal section through a ridge covering in which the ridge cover elements shown in Figures 1 to 3 were used,
Figure 11 is a perspective view of a third embodiment having an apex groove,
Figure 12 is a side view of the element shown in Figure 11,
Figure 13 is a side perspective view of a fourth embodiment of a ridge cover element,
Figure 14 is a side perspective view of a fifth embodiment of a ridge cover element, and
Figure 15 is a cross-section on the line
II-II of Figure 14.
Referring now to Figure 1, there is shown a ridge cover element 1 which is shaped similarly to a ridge brick. It is preferably made of plastics material, but instead of plastics material it is obviously also possible to make the element from other materials, such as ceramics or sheet metal. The cover element consists of an elongated cover plate which has a curved cross-section which has side parts 2 arranged to extend downwardly over a ridge board (reference 7 in Figure 6).
The cover element is arranged to engage over the ends nearer the ridge of covering plates or roof tiles and bears sealingly thereagainst, this and other identical cover elements being laid in the direction of the ridge in such a manner that parts of the elements overlap. In the overlapping regions, the ridge cover elements are formed with a step 3, the height of which corresponds to the thickness of the material of a hip brick. In Figure 3, which shows a front view of a ridge cover element, it can be seen that the step extends over the entire curvature and at the sides merges into holding parts. Slightly different configurations are shown in Figures 1 and 3 in order to enable two different embodiments to be illustrated.
In the region of the steps, the elements are formed from outside with corrugations 5 (indentations and projections) extending over the curvature. Since the hip bricks are to be laid, in the region of the step, which is formed with corrugations, particularly good contact is here obtained between the various ridge cover elements and the hip elements, while a sealing medium can easily be applied in this region.
The side parts with the edge profiles diverge in relation to the ridge cover element, so that that region of the cover element which is shown at the top in Figure 1 is narrower than the bottom region.
An example of the manner in which the ridge cover elements may be laid is shown in
Figure 6 and it will be seen that the ridge cover elements 1 are fastened to a ridge board 7 with the aid of nails 9. The side parts 2 have sealing strips 13 disposed under them, the sealing strips being held in a
C-section portion 14 of the cover element which is open at the bottom. The elastic sealing strip 13 clings to the adjoining covering plates 15, adapting itself to the roof shape. The sealing strip does not extend over the entire length of the cover element, but is rather shorter, since one cover element is pushed over the corrugated region 17 of an adjacent one. A ridge clip 28 of the type shown in Figure 10 is inserted between the overlapping regions of the ridge cover elements but is omitted in Figure 6 for clarity in representation of the other elements.
After two ridge cover elements have first been laid at the beginning of the ridge, the further laying of elements continues. From
Figure 1 it can be seen that at the apex ends of the cover elements holes or slots 6 are formed with the aid of which overlapping cover elements can be nailed in position, the inset Figures showing the alternatives of closed slots 6' or rows of holes 6".
From Figure 3 it can also be seen that for the purpose of stiffening the edge regions a closed stiffening section 4 can a so be present.
Figure 4 and 5 show a modification of the arrangement shown in Figure 1, in which a sealing strip or a section 27 holding the sealing strip is disposed under the edge region in such a manner that the sealing stnps laid under the latter or the holding sections extend parallel to one another on both sides. When laid in the manner shown in Figure 6, the edge regions at the joints do not partly project but may lie flush with one another and form a closed side.
In Figures 7, 8 and 9 various forms of sealing strips are shown, which extend the edges of the elements on the covering side downwardly and form a transition to the covering plates. In Figure 7 the edges end in a C-section portion 14 (Cf. Figure 3) which is open in the downward direction and in which an elastic sealing strip 13 is embedded. In Figure 8 the edge on the covering side ends in a web which is bent over downwards and which forms a L-shaped cross-section portion 19, an elastic sealing strip 13' being fastened in the L-shaped cross-section.In Figure 9 an embodiment is shown in which the edge on the covering side is in the form of part of a closed hollow section 18 in which a groove 21 open at the bottom is formed, this groove carrying a web 22 which at least over its free length projects into an elastic sealing strip 13" fastened on the hollow section, thus stiffening and retaining the said sealing strip.
Figure 10 shows how ridge cover elements 1 should be laid when ridge bricks 24 are laid over them. The cover elements 1 are laid in such a manner that the stepped regions 3 and 23 come to lie one over the other. The vertical riser 3' of the step 3, is used as an abutment for the edge of a ridge brick 24. A ridge clip 28, which is fastened at the bottom on the ridge board, is bent in such a manner that it passes around the step and that its bent region embraces the upper part of the ridge brick laid at the top. The ridge bricks 24 are therefore secured in relation to one another with the aid of the ridge clips 28. The ridge is thus covered a part at a time from left to right, the ridge bricks being secured immovably on both sides. At each end of the ridge a ridge end plate may be nailed to the ridge board, this plate optionally being formed with ventilation holes.
Figures 11 and 12 show another form of construction of a ridge cover element, which permits the ridge clips 28 to be satisfactorily embedded. The ridge cover element 1 shown in Figures 11 and 12 is formed with a groove 30 along its apex, the groove extending from the step region 3 to the region 23 and having a continuously decreasing depth, as can be seen in Figure 12. In the region of the step 3, the groove has a height equal to the full height of the distance from the apex of the cover element to the apex of the step curvature. The depth of the groove decreases gradually and is practically zero in the region of the other end 23. The groove, which may also be formed over only part of the apex, permits the insertion of the ridge clips 28 in a particularly successful manner, since considerable bending of the clip to lay it in the manner shown in Figure 10 is here not requied.Otherwise the laying and utilisation of the clips is the same here as for the ridge cover element in Figure 6.
Figure 13 shows a ridge cover element which is in the form of a double element, that is to say has the length of two ridge bricks. The speed of laying can thus be substantially increased. In the element shown in Figure 13 an apical groove (cf.
groove 30 in Figures 11 and 12) is interrupted by reinforcing beads 34, each of which is of the same height as the apex of the cover plate.
In addition, the element is formed with ventilation holes 33 which penetrate laterally of the groove through the cover plate. It is however also possible for such ventilation holes to be formed in the bottom of the groove. The ridge bricks are usually fastened on the ridge cover with the aid of ridge clips. In order to make it possible for the ridge clips to be laid flush, a groove extending along the apex of the element is formed above the step and receives the ridge clips. For reasons of production it is also possible for the groove to extend over the entire axial length of the ridge cover element, gradually decreasing in height. In addition, it is possible for the groove to be interrupted over its length by reinforcing beads.
Figure 14 shows another ridge cover element 1 which is also preferably made of plastics material (e.g. polyvinyl chloride) by a deep-drawing process. Instead of plastics material it is obviously also possible to use other materials, such as ceramics or sheet metal. The cover element consists of an elongated cover plate of curved crosssection, which has side parts arranged to extend downwards over the ridge board and to engage over the ends nearer the ridge of the covering plates or roof tiles the element bearing sealingly against them by means of sealing strips 13.
The ridge cover element is formed with strong ribs 120 and 121 in the form of beads.
In addition, a groove 30, which is not interrupted by the ribs, is formed on the apex of the element for ensuring that the element will lie against the ridge board without a gap so that the element can be nailed in psoition without any gap disturbing the existing fastening. When the element is in position it can thus be walked on and its adaptation to the ridge board is facilitated.
In the region of the central groove, the element thus lies on the ridge board over its entire length, without a conicity for the application of covering plates or roof tiles bemg impaired.
In a manner similar to that shown in
Figure 6, the ridge cover elements of Figures 14 and 15 are nailed on a ridge board 7 and the side parts 2 have disposed beneath them the sealing strips 13 which are made for example of an elastic foamed material, and have a wide bearing surface 14 adhesively bonded under the edges and a crosssection which tapers in the direction of the covering plates or roof tiles. The crosssectional area which is deformable when the cover elements are pressed onto the ridge board amounts to about 10 to 40 square centimetres. The starting material is there fore the relatively thin sealing strip of substantially rectangular or square shape.
The strips are composed of relatively soft foamed material (Shore hardness 5 - 20), which makes it possible for the sealing strips to lie closely and softly to form a seal over protuberances and depressions in the plates and tiles lying beneath them. Thus the space under the cover element may be made tight in relation to snow, dust, and rain.
The sealing strips extend over the entire length of the cover element with the exception of a short distance at the step 3. On the other hand, at one end face 116 of the element they project in the axial direction over the overlap region (at 117). When the ridge elements are laid one against the other, the projecting parts 117 form a connecting joint which ensures reliable sealing in the axial direction also.
From Figure 14 it can also be seen that in the centre, in the step region 3', a slot 122 is formed through which a nail can be driven, a single nail being usually sufficient to fasten the element. After the nail has been driven some distance into the ridge board, the element 1 can be adjusted axially to position it accurately, adjustment being possible over the entire length of the ridge. After the exact position has been determined, the nail is driven in.
Moreover, on both sides of the apex of the element there may be formed ventilation holes 123 and 124 having an inside cross-sectional area of from 1 to 5 square centimetres.
The double element shown in Figure 14, which has the length of two ridge bricks, permits a high laying speed to be achieved.
The groove 30 is interrupted by stiffening the ribs 120, which at their highest point project slightly beyond the curved cover plate of the ridge element, so that good bottom ventilation of the ridge tiles installed is also ensured. In the region of the step 3 the rib is interrupted by the groove, so that the ridge clip can be inserted. The depth of the groove decreases continuously in the direction of the end remote from the step 3 or 3'. In the region of the step the groove has the full depth, the depth decreasing gradually and being practically zero in the region of the other end 116.
In the embodiment shown in Figures 14 and 15, the sealing strip has a triangular shape, the length of the side of the triangle being 5 to 8 cm. and inside angle a of the tip of the triangle being from 15 to 60". A relatively acute angle is preferably formed, because a relatively elongated triangular shape firstly forms a relatively easily deformable sealing lip, which is then followed by adequate material in the direction of the lower edge, so that the desired action is achieved. The tapering shape of the sealing lip further makes it impossible for water to rise from below in the sealing lip.
Through the use of foamed material sealing strips of triangular cross-sectional shape, the fastening of the strip in the installation of the ridge cover element is simplified, since the edges at the covering end can simply have a sealing strip secured to them by adhesive bonding.
The cover element may be made of a PVC sheet of a thickness of about 1 to 3mm., this sheet being bent into a roughly C-shaped cross-section, the sealing strips 13 being disposed under its edges at the covering ends. The element is shoulderless at the edge.
