Name of Applicant: FRIEDRICH OSSENBERG-SCHULE SOHNE GmbH CO. KG Actual Inventor: JAN KAEMPER Address for Service: COLLISON CO., 117 King William Street, Adelaide, S.A. 5000 Invention Title: The following statement is a full description of this invention, including the best method of performing it known to us: The invention relates to an arrangement comprising a roofing part and a spring clip for laying roofing tiles, bricks, ridge tiles or similar roofing parts on the batten of a roof, where the roofing part is shaped on its underside which faces the batten, which shaping interacts with a spring clip that can be attached to the batten.

GB 2321479 A discloses an arrangement for laying roofing parts on the batten of a roof.

Usually, the ridge tiles or other roofing tiles are.laid like scales, overlapping one another. In order to secure them in place, ridge clips are provided which can be attached to the ridge tile. In order to allow an invisible arrangement of the ridge clips, according to the prior art it is proposed that the ridge tile has on its underside a longitudinal web that projects orthogonally with respect to the plane in which it is being laid, with the ridge clip having a two-legged, u-shaped clip opening into which the longitudinal web of the ridge tile can be inserted in the 15 desired assembled position. The clip opening has retaining means which allow the longitudinal web to be inserted but prevent it from being pulled out in the direction opposite to the insertion direction.

Although this design is advantageous per se, the securing in place is often insufficient because there is no sufficient clamping of the retaining means to the 20 longitudinal web of the tile. According to the prior art, it has already been proposed that the longitudinal web should have a slot, a recess or a depression .in the form of an undercut for the latching reception of the retaining means or of the retaining edges of the retaining means in the desired assembled position.

Such a design is indeed possible, with such a design also leading to a e 25 particularly secure retaining of the roofing part, although the production of an appropriate roofing part is costly since the slot, the recess or the depression has to additionally be formed. This is difficult above all because usually the roofing part is made in a mould and then simply has to be removed from the mould, whereas the forming of slots, recesses or depressions is not possible using this method of production. Such roofing parts may be moulded for example from concrete or clay and then fired.

Based on this prior art, it is an object of the invention to provide an arrangement of the generic type which ensures simple manufacture in particular of the roofing parts and in which after final assembly of the parts high tensile forces can act on the roofing parts without the connection to the spring clip being loosened or released.

In order to achieve this object, it is proposed that the shaping comprises a groove-like recess which opens out towards the underside of the roofing part, and that the spring clip has at least one web that projects in the direction of the recess, can be inserted into the recess and has a retaining angled portion at the end, where in the desired assembled position the web bears, with the region which is adjoined by the retaining angled portion, on the first flank of the recess, the retaining angled portion bears with its free end on the second flank of the recess, and an acute angle is enclosed between the web and the retaining angled portion.

By virtue of the design according to the invention, it is possible to design the roofing part, which is otherwise shaped as desired, with a groove-like recess on the underside. This design can be realised without difficulty in the conventional S: manufacture of roofing parts, where in particular the manufacture does not pose any problems since no undercut or the like is necessary. The spring clip is also a relatively simple component. The spring clip may be attached to the batten of the roof in a suitable manner, for example by means of screw nails, screws or 25 even by hooking it on a roof batten. Once the spring clip has been arranged in the correct position, the roofing part with the groove-like recess can be pushed onto the free end of the spring clip so that the web bears on the first flank of the groove-like recess and the retaining angled portion bears with its free end on the second flank of the groove-like recess and is supported in a retaining manner. In the process, an acute angle is enclosed between the web and the retaining angled portion. In order to ensure that an acute angle is produced in the desired assembled position between web and retaining angled portion, the distance of the two groove flanks from one another is smaller than the length of the retaining angled portion. In such an arrangement the securing in place of the roofing part is ensured, with the connection to the spring clip not being released or loosened even when high tensile forces are applied to the roofing part, but rather the connection thereby being further improved because the retaining bearing of the spring clip on the two groove flanks is increased even further. The groove may accordingly be made to be deep, so that, even at different distances of the roofing part from the roof batten, the spring clip engages in the groove-like recess and a secure fit is ensured. Virtually a stepless height adjustment is thus achieved, with the same retaining force always being produced. The spring clip should be made of an elastic material, it also being possible for plastic to be used.

One embodiment is seen in that the groove-like recess is made in a thickened material layer of the roofing part.

By way of example, in a ridge tile a thickened portion may be provided on the underside in the region of the valley of the ridge tile, it being possible for the corresponding groove-like recess to be made in this thickened material layer.

As a result there is enough material to form and make the groove.

eg.* Alternatively, it may also be provided that the groove-like recess is formed between two material webs that project from the underside of the roofing part.

0 Appropriate material webs may be integrally formed on the underside of any S: 25 roofing parts, with the groove-like recess being made between the material webs. The facing sides of the material webs form the groove flanks.

In order to facilitate the removal of roofing tiles or the like from moulds during manufacture and to ensure that this takes place without damaging the groovelike recess, it is additionally provided that the flanks of the groove-like recess are shaped so as to run in a slightly divergent manner.

The angle of divergence may correspond to the conventional demoulding angles.

Preferably, it is provided that the groove-like recess runs over a relatively large area of the length of the roofing part.

As a result, it is possible for the assembly staff to fix the parts to one another at any longitudinal area of the roofing part, and/or it is also possible for the roofing part to be moved after it has been pushed onto the spring clip in the longitudinal direction of the groove-like recess, in order to obtain the desired position.

One development that is preferred under some circumstances is seen in that the web of the spring clip has a foot that can be placed on the batten, which foot 15 can be attached to the batten by means of a screw.

o *By way of example, the foot may be an integrally formed angled portion of the spring clip which is provided with a hole, with the screw being passed through in the region of the hole and screwed into the batten.

It is particularly preferably provided that inthe longitudinal direction in which the 20 groove runs the spring clip has two webs next to one another with retaining angled portions that are angled in opposite directions.

o eo ooO As a result, not only is a high retaining force achieved but also the assembly is facilitated since a precise assembled position is automatically established on account of the symmetric arrangement.

Furthermore, it is preferably provided that the spring clip consists of a strip of spring steel sheet.

Accordingly, the spring clip may be a simple punched bent part which is costeffective to manufacture.

In addition, it is preferably provided that the end retaining edge of the retaining angled portion is directed at right angles to the assembly insertion direction of the roofing part.

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

In the figures: Fig 1 schematically shows a first embodiment in a front view, Fig 2 shows a view of part of a roofing part, Fig 3 shows a variant in the view shown in Fig 1, Fig 4 shows the variant in the view shown in Fig 2, Fig 5 shows a detail analogous to Fig 1 in the desired assembled position, Fig 6 shows a view of a detail.

5o55 The drawing schematically shows a roofing part 1 which is shown in the desired :g.•assembled position in Figs 1 and 3 and 5 whereas in Figs 2 and 4 the roofing part is shown with the underside pointing upwards. Such roofing parts may be bricks, ridge tiles, concrete roofing tiles or the like. These roofing parts are fastened to the batten 2 of a roof, as shown schematically in Fig 5. On its side which points downwards in the assembled position, the roofing part 1 has a 6 shaping which interacts with a spring clip 3 that is attached to the batten. The shaping forms a groove-like recess 7 which opens out towards the underside of the roofing part 1. In the example of embodiment, the spring clip 3 has two webs 4 that project in the direction of the recess 7, can be inserted into the recess 7 and have a retaining angled portion at the end. In the desired assembled position, which is shown by way of example in Fig 1, Fig 3 and Fig the web 4 bears, with the region which is adjoined by the respective retaining angled portion 5, on the first flank of the recess 7 while the retaining angled portion 5 bears with its free end, which is preferably designed with sharp edges, on the second flank of the recess 7. In the desired assembled position, an acute angle is enclosed between the web 4 and the retaining angled portion As shown in particular in Fig 1, Fig 2 and Fig 3, the groove-like recess 7 may be made in a thickened material layer of the roofing part.

According to the example of embodiment shown in Figs 3 and 4, the groove-like recess 7 is formed between two material webs 6 that project from the underside of the roofing part 1.

The flanks of the groove-like recess 7 diverge in the direction of the groove opening, with the angle of divergence corresponding to the demoulding angle which is necessary to remove the part from the mould during the manufacture of the roofing part 1.

As can be seen in particular from Figs 2 and 4, the groove-like recess 7 runs over a relatively large area of the length of the roofing part 1.

The web 4 of the spring clip 3 has a foot 8 that can be placed on the batten 2, which foot is attached to the batten 2 by means of a screw 9 that passes through the foot at a hole.

As can be seen in particular from Fig 6, the spring clip consists of a strip of spring steel sheet, where two webs 4 that are separate from one another and comprise retaining angled portions 5 are integrally formed on the foot 8, said retaining angled portions being oriented in opposite directions from one another.

According to this design, it is extremely simple to place the roofing part 1 in the correct position on the spring clip 3 and effectively connect it to the spring clip 3, so that a secure position of the roofing part 1 on the roof batten 2 is achieved.

In the event of tensile forces (in particular including wind drag or the like), the retaining action of the spring clip 3 is increased even further since the retaining angled portions increasingly bear with greater force against the corresponding regions of the groove-like recess 7. The length of the retaining angled portion is in any case greater than the distance between the groove flanks of the recess 7, so that a secure barbed latching and locking is achieved.

The invention is not restricted to the example of embodiment but rather can be varied in many ways within the context of the disclosure.
