Abstract

Clip (1) to secure the side structure of a roof tile has a hook to grip over the side body of the tile, and a clamping foot to grip under the roof beam. The clip (1) comprises injection molded plastic. The foot section (2) has teeth (3) to grip into the wood beam (4), angled towards the vertical leg of the clip structure.

Description

The invention is directed to a side fold clip Securing roof tiles with a hook part for reaching over of the roof tile side rebate and a clamp foot for reaching under a roof batten.

From GB-A-2 228 502, GB-A-2 276 400, Brackets are known from AU-A-521 428 and US-A-4 034 528. By showing one Advertising document from the company Braas Dachsysteme a "universal storm clamp" made of metal. A metallic one intervenes Claw under the roof batten, being on the claw over a Angled sheet metal tie rod is provided on the a hanger with a claw to engage in the Side fold of the roof tile is slidably arranged. is the storm clamp is positioned with the grip of the Roof batten by means of the claw and overlapping the hanging bracket over the side fold, the tie plate is down folded over and thus fixes the suspension bracket in its position.

This known solution already offers a number of advantages, so it is comparative, especially in its manufacture expensive, the metal is usually galvanized and therefore expensive, so that a goal of the present Invention lies in these side seaming clips economically.

This object is achieved according to the invention according to claim 1.

Because of the comparable dimensions for roofing for is available to users of such brackets it is possible to form these side fold clamps in one piece, however, adaptability may also be appropriate different overgrip or undergrip dimensions to enable.

Here, the invention provides that the side fold bracket is formed in two parts with an overlapping hook having part and a part having the clamping foot, where the two elements are fixed to each other.

There is a particularly simple type of adjustment According to the invention in that the overlapping hook Part has a locking cam on its outer surface, wherein the hook element can be fixed on the locking cam. With this latching is a simple interlocking or Stacking possible, any bending work or the like, as are necessary in the prior art, are unnecessary here.

It is advantageous how this is the invention also provides the hook element a sawtooth slot has, in which the locking cam with outward-pointing Counter toothing is performed.

The invention also provides that the elements of the side fold bracket made of a glass fiber reinforced polyamide are to withstand the necessary stresses.

In addition, the invention can also be embodied therein exist that the part having the hook hook made of a 30-50% PA glass fiber or metal and that Part having a clamp foot is formed from polyamide.

7a and 7b

a modified embodiment of a two-part side fold bracket in the mounting position and loading position.

The one-piece side seam clamp shown in FIGS. 1 and 2, generally designated 1 is essentially in Side view L-shaped, with a lower L-leg 2, which has a toothing 3 and for reaching under a roof batten 4 indicated only by dashed lines 4 serves, and an upward-pointing L-leg 5, on the an over hook 6 is formed to overlap the Side fold 7 of a fragment indicated only in Fig. 2 Roof tile 8.

The side fold clip 1 is advantageously made of a glass fiber reinforced Made of polyamide, it can be mass-produced be produced inexpensively.

In order to be able to adapt to different heights, 3 ff. is the side fold clamp, generally designated 1a, formed in two parts, with an essentially L-shaped design, a toothing 9 having lower part 10 and one upper element 11, which has the over hook 6 '.

As can be seen in particular from FIGS. 3 to 5, the upward-pointing web 12 of the element 10 with a Longitudinal groove 13 provided that fine toothing on the inside 14 has.

In contrast, the upper element 11 carries a locking cam 15 as an approximately T-shaped block, with the inward-facing T-web 16 equipped with external teeth 17 on both sides with the internal toothing 14 of the slot 13 of the lower element 10 corresponds.

The width of the slot 13 is chosen so that always a clamping force presses the teeth 14 and 17 into each other, so that the side fold bracket in the once taken Location is fixed. A release can only be done by force, about by one in the upper free space of the slot 13 Insert the screwdriver and turn it as far as that the outer toothing 14 from the inner toothing 17th on the locking cam 15 triggers.

The installation situation of the two-part side fold bracket 1a to overlap the side fold 7 of a roof tile 8 and the Reaching under a roof batten 4 is simplified in FIG. 6 played.

7a and 7b is a modified embodiment a two-part side fold clip shown with an L-shaped lower element 10b and not there upper hook shown in detail, overlapping hook Element 11b. The leg 2b of the element 10b with the toothing 3b has at its free front end an additional, enlarged single tooth 18, which in the Bottom of the roof batten 4 can dig, as this in the 7a and 7b is indicated.

Fig. 7a shows the mounting position, i.e. here runs the Web 2b essentially parallel to the underside of the roof batten 4th

In Fig. 7b the side seam clamp is shown under load. Here, the tooth 18 digs into the underside the roof batten 4, the rest of the teeth come with a Area of the underside of the roof batten 4 in contact. By the enlarged tooth 18 is much stronger Clamping, the tooth 18 being very pointed and is inclined towards the leg 10b. By this design it is possible that not only the bracket always with the load, but also with relief correct position in relation to the roof tile to be clamped and the roof batten 4 lies.

Of course, the described embodiment of the invention still change in many ways without the Leaving basic ideas, so the arrangement of the locking cam of the assigned slot be reversed, i.e. the lower part 10 is with the locking cam and the upper part 11 equipped with the slot u. Like. more.
