Description

Translation Assembly for the installation of roofing components on the battens of a roof The invention concerns an assembly for the installation of roof tiles, flat tiles, ridge tiles or similar roofing components on the battens of a roof, whereby the roofing component has on its underside facing the battens a formed-out part that cooperates with a spring clip attached to the battens.

From DE 197 02 439 C1 an assembly for the installation of roofing components on the battens of a roof is known. Normally the ridge tiles or also other roofing plates are installed in a scale-like overlapping position. To secure them in place, ridge clips are proposed which are attached to the ridge purlin. To make an invisible arrangement of the ridge clips possible it is proposed in accordance with the state of the art that the ridge tile has on its underside a longitudinal ridge running orthogonally to the installation surface, whereby the ridge clip has a two-legged ushaped throat into which the longitudinal ridge of the ridge tile is fitted on installation. The clip throat has locking devices permitting the insertion of the longitudinal ridge, but prevent the ridge from being pulled out against the direction of insertion.

Although this design is in itself advantageous, the securing in position is often not sufficient, because there is no adequate clamping of the locking devices to the longitudinal ridge. According to the state of the art it has already been proposed that the longitudinal ridge must have a slot, a recess or a depression in the form of an undercut for the lock-in reception of the locking devices or rather the locking edges of the locking devices on installation. Such a design is possible, whereby this results in a particularly secure holding of the roofing component, but the manufacturing of such a roofing component is more expensive, because the slot, recess or depression must be formed-in additionally. This is above all difficult because normally the roofing component is made in a mould and is then simply removed from the mould, whereby in this manufacturing process the forming-in of slots, recesses or depressions is not possible. Such roofing components can e.g.

be moulded from concrete or also moulded and baked from clay.

Based on this state of the art the purpose of the invention is to create an assembly of a similar type guaranteeing easy manufacture in particular of the roofing components and with which after final assembly strong tensile forces can act on the roofing components without loosening or undoing the connection with the spring clip.

To achieve this purpose it is proposed that the formed-out part includes a groovelike recess opening out onto the underside of the roofing component and that the spring clip has at least one leg projecting towards the recess, whereby this leg, which terminates in an angled locking part, can be inserted into the recess. In the required mounting position the section of the leg adjacent to the angled locking part is braced on the first flank of the recess, the free end of the angled locking part is braced on the second flank of the recess and the leg and the angled locking part enclose an acute angle.

The design as per invention makes it possible to provide any moulded roofing component with a groovelike recess on the underside. This design can be realised without difficulty in the usual manufacture of roofing components, whereby in particular the manufacture does not present difficulties, because there is no need for an undercut or the like. The spring clip is also a relatively simple building component and can be fastened in a suitable manner to the roof battens e.g. by means of screw nails, screws or by hooking onto a batten. After the spring clips have been properly positioned, the roofing component can be mounted with its groovelike recess on the free end of the clip so that the leg rests against and is braced on the first flank of the groovelike recess and the free end of the angled locking part rests against and is braced on the second flank. An acute angle is enclosed between the leg and the angled locking part. To guarantee that an acute angle is obtained between leg and locking part, the distance between the groove flanks is smaller than the length of the angled locking part. With such an assembly the secure position of the roofing component is guaranteed, whereby even if high tensile forces act on the roofing component, the connection with the spring clip is not undone or loosened, but on the contrary is improved, because the locking bracing of the spring clip on the two flanks of the groove is reinforced. The depth of the groove can be suitably dimensioned so that for different distances of the roofing component from the battens engagement of the spring clip with the groovelike recess will be effected and a secure seat will be guaranteed. This is tantamount to a stepless height adjustment, whereby the same holding force is always achieved. The spring clip must be made of resilient material whereby plastic may also come under consideration.

A variant embodiment may be one where the groovelike recess is formed out in a thickened layer of material of the roofing component. A ridge tile may e.g. have a thickening on the underside near the throat, whereby the corresponding groovelike recess can be moulded-in in this thickened layer. This provides ample material for the shaping and moulding in of the groove.

Alternatively it may be provided that the groovelike recess is formed between two ridges of material projecting from the underside of the roofing component.

Ridges of material can be formed-on to any roofing components whereby the groovelike recess is formed out between these ridges. The opposing sides of the ridges constitute the flanks of the groove.

To facilitate the demoulding of roofing tiles or the like in the manufacture and to ensure that this happens without damage to the groovelike recess, it is furthermore proposed that the flanks of the recess diverge slightly. The angle of divergence can be identical to the usual demoulding angle.

Preferably it is provided that the groovelike recess runs along a substantial part of the length of the roofing component.

This enables the installer to attach the components to each other at any point along their length and/or it also enables him to shift the roofing component after mounting on the spring clip along the length of the groovelike recess to achieve the required position.

A sometimes preferred further development is one where the leg of the spring clip has a foot that can be placed against the battens and fastened to them with a screw.

The foot can e.g. be a formed-on angled part of the spring clip with a hole for screwing the foot to the batten.

It is particularly preferred that the spring clip has two legs with opposed angled locking parts positioned side by side in the longitudinal direction of the groove.

This not only achieves a high holding force, but it also facilitates installation, because the symmetrical arrangement will automatically provide precise positioning.

It is furthermore provided that the spring clip consists of a strip of spring steel.

Consequently the spring clip can be a simple stamped and bent metal part which is cheap to manufacture.

A further preferred provision is one whereby the outside locking edge of the angled locking part is oriented at right angles to the mounting direction of the roofing component.

An embodiment of the invention is shown in the drawings and described in more detail below.

Illustrations: Fig. 1 a diagrammatic front view of a first embodiment Fig. 2 a detail view of a roofing component Fig. 3 variant of the view as per Fig. 1 Fig. 4 variant of the view as per Fig. 2 Fig. 5 detail as per Fig. 1 in required mounting position Fig. 6 detail view The drawings give a diagrammatic view of a roofing component shown in the required mounting position in Figures 1, 3 and 5, while Figures 2 and 4 show the roofing component with the underside up. Such roofing components can be roof tiles, ridge tiles, concrete roof tiles or the like.

The roofing components are fastened to the battens 2 of a roof as shown in Fig. In mounting position the underside of the roofing component 1 has a formed-out part cooperating with a spring clip 3 attached to the battens. The formed-out part forms a groovelike recess 7 which opens out onto the underside of the roofing component 1. The spring clip 3 has legs 4 projecting towards and insertable into the recess 7 whereby these legs have angled locking parts at their ends. In the mounting position as shown by the examples in Figures 3 and 5, the section of the leg 4 adjacent to the angled locking part is braced on the first flank of the recess 7, while the free and preferably sharp-edged end of the angled locking part 5 is braced on the second flank of the recess 7. In the mounting position an acute angle is enclosed between the leg 4 and the angled locking part A shown particularly in Figures 1, 2 and 3 the groovelike recess 7 may be formed out in a thickened layer of the material of the roofing component. As the embodiment as per Figures 3 and 4 shows, the groovelike recess 7 is formed between two ridges of material 6 projecting from the underside of the roofing component 1.

The flanks of the groovelike recess diverge towards the mouth of the groove whereby the angle of divergence is identical to the demoulding angle which is required for the demoulding of the part 1 during its manufacturing process.

As can be seen particularly from Figures 2 and 4 the groovelike recess 7 runs along a substantial part of the length of the roofing component 1.

The leg 4 of the spring clip 3 has a foot 8 which can be placed against the batten 2 and fastened to it by means of a screw 9.

As can be seen particularly from Figure 6 the spring clip consist of a strip of spring steel whereby two separate legs 4 with angled locking parts 5 are formed-on to the foot 8 and whereby these locking parts are oriented in opposite directions.

As this illustration shows it is extremely simple to mount the roofing component 1 in the right position on the spring clip 3 and to effectively connect it with the spring clip 3 so that a secure position of the roofing component 1 on the batten is achieved. Under the action of tensile forces (especially also wind suction or the like) the locking action of the spring clip 3 becomes even stronger, because the angled locking parts brace themselves with increasing force on the corresponding areas of the groovelike recess 7. The length of the angled locking part 5 is thereby in each case greater than the distance between the flanks of the recess 7 so that a secure barblike locking in place is achieved.

The invention is not limited to the embodiment, but is multivariable within the scope of the disclosure.

All new, individual and combined features disclosed in the description and/or drawings are considered essential parts of the invention.
