Description

The invention concerns a wind-resisting clamp for fixing roof tiles to a roof sub-construction, in particular to the roof battens, whereby the wind-resisting clamp consists of a hooking part for hooking onto the edge or interlocking edge of a roof tile and a fastening part for attachment to the sub-construction and the shank of the hooking part basically projects orthogonally from the shank of the fastening part.

A wind-resisting clamp for roof tiles consisting of a metal strip is known from DE 42 03 676 Al. At its end the clamp has a hook with which it can be hooked 1 0 over the edge or an interlocking edge of a roof tile. At the other end the strip has a curl through which a nail can be driven into a roof batten or the like. With this design it is necessary for different distances between the edge or the .lateral or head end interlocking edge of the tile and the roof battens to use a clamp of a different length in order to compensate for this difference.

1 5 Moreover, the installer fixing the particular clamp to a roof batten and a tile *.**must take account of the overlap of the tile already in place and the tile to be laid over it and clamped and drive in the nail accordingly. For greater distances nails of different length must be selected. The arrangement and fastening of the clamp must take place in such a way that the clamp exerts a tensile force on the tile so that it is pulled against the tile underneath and the "roof batten thus ensuring storm-proof and rattle-proof installation. This requires a high degree of skill on the part of the installer.

o• From the publication referred to we also know a wind-resisting clamp whereby a first end is attached to a roof batten and a second end is hooked onto the edge of a tile, whereby the two elements are connected by a winding in the form of a loop. The element is made of steel and has spring properties. With this design the installer can hook one end of the clamp around a roof batten whereby the hook must of course fit the width of the roof batten so that for different widths different hooks must be used. Furthermore, the installer can 3 0 then bend the hooking end so as to impart spring force to it and clip it onto the edge of a roof tile. Here too the hooking end must have the appropriate length to be hooked onto the edge of the tile, whereby different distances between the edge of the tile and the roof battens require different hook lengths.

As a rule the spring tension is not sufficient to press the tile with the required force against the sub-construction.

On the basis of this state of the art the object of the invention is to create a wind-resisting clamp of a similar type which can be easily and accurately positioned and which makes it possible to use one and the same clamp for roof battens of different dimensions and for different distances between the edge of the roof tile and the roof battens. In particular an object of the invention also is to create a wind-resisting clamp which can be used for different distances of the hooking point horizontally or vertically from the roof batten and despite variable positioning does not permit greater strain paths as 1 0 a result of bending moments.

To achieve this object it is proposed that the shank of the hooking part be attached along the shank of the fastening part at a variable distance from the end of the fastening part that is attached to the sub-construction and/or that the shank of the hooking part be arranged along the shank of the fastening part at 1 5 a variable distance of the hooking end from the shaft of the fastening part.

The fact that the shank of the hooking part is attached along the shank of the **fastening part at a variable distance from the end of the fastening part that is 0 attached to the sub-construction, makes it possible to arrange the hooking end at a variable distance from the matching roof batten or the like so that even 0 when the hooking requirements along the roof surface vary, it is still possible to hook the clamp onto the tile.

Alternatively or additionally (the additional possibility is preferred), it is also possible to adjust the hooking part at a variable vertical distance from the roof plane so that it is also possible to secure roof tiles with one and the same 2 5 wind-resisting clamp when their receiving edges are at a variable distance from the roof plane or the roof batten plane. For this it is necessary to arrange the shank of the hooking part along the shank of the fastening part at a variable distance of the hooking end of the hooking part from the shank of the fastening part. This arrangement produces a universally useable wind- 3 0 resisting clamp which is adjustable in two directions and therefore is suitable for the most diverse dimensional ranges.

It is preferable that the fastening part can be fixed to a roof batten as it basically projects orthogonally from this roof batten and extends parallel to the roof surface and that the hooking part projects orthogonally from the fastening part and specifically at right angles to the roof surface.

In the desired fixing position the fastening part extends essentially parallel with the projected roof plane whereas the hooking part projects orthogonally outwards from this roof plane. This orthogonal arrangement of fastening part and hooking part provides the means for adjustment of different distances and heights in the simplest possible way.

Preferably it is provided that the shank of the fastening part is an oblong body whose length is a multiple of the cross-sectional dimension of the shank of the 1 0 hooking part.

The length of the oblong body determines the adjustment range for the variable distances.

*0 Additionally it is preferably provided that the shank of the fastening part 'lengthwise has several mutually parallel and interspaced through-holes for 1 5 the shank of the hooking part. This makes a stepwise adjustment at variable "distances possible, whereby the through-holes also feature guideways for the *i *shank of the hooking part so that swivelling of the hooking part in relation to the fastening part is not possible.

Furthermore it is preferably provided that the shank of the hooking part can be 2 0 inserted to an infinitely variable depth into the through-holes of the shank of the fastening part and that in the required position its free hookless end can S" be bent around the edge of the shank of the fastening part opposite to the hook.

With this embodiment it is e.g. possible to already prepare the relevant clamp in the factory to the stage where the shank of the hooking part is inserted into the required through-hole and the free hookless shank end is bent in the required position around the edge of the shank of the fastening part opposite to the hook so that a wind-resisting clamp with fixed distance adjustment is produced. This fixed arrangement is e.g. advantageous if a customer orders a 3 0 number of clamps of identical size. These clamps can then be adjusted and supplied according to the customer's wishes. However, it is also possible to supply the clamps in individual parts so that the user can assemble them according to his requirements. Alternatively, it is also preferably possible that the shank of the hooking part can be inserted stepwise into the through-holes of the fastening part to different depths, whereby the shanks of the hooking part and the fastening part, in particular the through-holes, feature arresters which permit insertion, but have a locking effect in the opposite direction.

This way it is possible both for the manufacturer and the user to easily obtain different distances for the same original materials. Thereby a special advantage is that e.g. the user can first attach the fastening part to the roof batten or the like and that after installation of the roof tile the hooking part is 1 0 inserted into the appropriate through-hole of the shank of the fastening part i.e. to a depth matching the required position. In this position the shank of the hooking part is then interlocked with the shaft of the fastening part ensuring a ":."permanent and rigid connection.

15 To facilitate the placing of the fastening part on the roof batten or the like it is 1 5 furthermore provided that a contact face of the fastening part or of its shank has projecting claws. The projecting claws achieve that the fastening part is supported for the installer on the roof batten or the like in an almost "immovable position before the fastening part is permanently fixed to the roof batten e.g. by means of a nail.

a"2 0 To facilitate the fixing of the fastening part to the roof batten it is moreover provided that a lateral face of the shank of the fastening part that is parallel with the through-hole for the shank of the hooking part, features a holding device and guideway for a fastener, in particular a nail.

To ensure that the spot where the nail is driven into the roof batten aligns with the extension of the shank of the fastening part, it is further provided that the holding device and guideway are so arranged that the nail encloses an acute angle with the lateral face of the shank of the fastening part and the nail point exits from the base surface of the shank facing the roof batten in line with the through-holes for the shank of the hooking part.

3 0 This arrangement achieves an almost moment-free placing of the fastening part on the roof batten, whereby moreover the inclined position of the nail provides easier access to the nailhead for the installer so that it is easy to strike without obstruction by the shaft of the fastening part.

Furthermore it is preferably provided that the hooking part is formed from strip metal.

A suitable metal strip ensures that the hooking part especially with its shank cannot rotate around its longitudinal axis relative to the fastening part, but is placed and held in a desired position, whereby the relevant through-hole in the shank of the fastening part closely matches the cross-sectional shape of the metal strip.

In some cases it is also preferably provided that the fastening part is a moulded plastic part.

1 0 A sometimes preferred variant is one whereby the hooking part has two opposed hooks at its end.

This makes it possible to overlap two edges or interlocking edges of tiles with one and the same hooking part.

It is also possible to combine more than one hooking part with the fastening 1 5 part.

Finally it can also be advantageous that the fastening part can be clipped on to the roof batten.

With such an embodiment the fastening part is not nailed to a roof batten, but clipped onto it as is known from the state of the art (DE 42 03 676 Al).

An embodiment of the invention is presented in the drawing and more fully described below.

Illustrations: Fig. 1 Side view of an embodiment of a fastening part of a wind-resisting clamp; Fig. 2 Ditto in a position rotated 900 around the vertical axis; Fig. 3 Ditto in top view; Fig. 4 View of detail IV of Fig. 1; Fig. 5 View of an embodiment of a hooking part; Fig. 6 Ditto in a position rotated 900 around the central longitudinal axis The drawing shows the individual parts of a wind-resisting clamp for fixing roof tiles to a roof sub-construction, e.g. roof battens. The clamp consists of a hooking part 1 which can be hooked onto the edge or interlocking edge of a roof tile with its hook 2. The clamp consists further of a fastening part 3 which is shown in Fig. 1 to 4. The fastening part 3 serves for the attachment to the sub-construction, e.g. a roof batten. After assembly of the parts the shank 4 of 1 0 the hooking part 1 projects orthogonally from the shank 5 of the fastening part 3, i.e. as per Fig. 1 projecting out of the drawing plane and as per Fig. 2 situated within the drawing plane.

S..In accordance with the invention the shank 4 of the hooking part 1 is attached along the shank 5 of the fastening part 3 at a variable distance from its end 6 1 5 which is fixed to the sub-construction. Alternatively or additionally (in the embodiment additionally) the shank 4 of the hooking part 1 is arranged along the shank 5 of the fastening part 3 with a variable distance of the hooking end 2 of the hooking part 1 from the shank 5 of the fastening part 3.

In the required fixing position the fastening part 3 is so attached to a roof 2 0 batten that it basically projects orthogonally from a roof batten and extends parallel to the roof surface formed by the roof battens. In this position it is fixed to the particular roof batten.

The hooking part 1 then projects orthogonally from the fastening part 3 i.e. at right angles to the roof surface so that it projects to the side on which the tiles 2 5 are installed.

In the embodiment the shank 5 of the fastening part 3 is a rectangular oblong body whose length is a multiple of the cross-sectional dimension of the shank 4 of the hooking part 1. Along its length the shank 5 of the fastening part 3 has several parallel interspaced through-holes 7 for the shank 4 of the hooking 3 0 part 1. This makes it possible to insert the shank 4 of the hooking part 1 to an infinitely variable depth into the through-holes 7 of the shank 5 of the fastening 8 part 3, whereby in the required position the free hookless shank end of the shank 4 is bent around the edge of the shank 5 of the fastening part 3 opposite to the hook 2 so that then the required position is achieved.

Alternatively and preferably it is also possible that the shank 4 of the hooking part 1 can be inserted stepwise to a variable depth into the through-holes 7 of the shank 5 of the fastening part, whereby on the shank 4 of the hooking part 1 there are snap-in holes 8 and on the shank 5 of the fastening part 3 there are locking projections 9 in the through-holes 7 which projections engage one of the snap-in holes 8. The locking projections 9 are designed so that in the 1 0 insertion direction of the shank 4 they permit free entry, but lock it in the opposite direction. This is achieved by chamfering the locking projections 9 in the insertion direction of the shank 4 whereas in the opposite direction they have a locking edge oriented orthogonally to the insertion direction so that the ">:"inserted shank 4 cannot be pulled out again without engaging the locking 1 5 projections 9. If the installer has incorrectly assembled the parts it is possible .o :to manually loosen the locking projections 9, because these are formed by slits in the lateral face of the shank 5 of the fastening part 3 and can therefore bent open by hand or with a screwdriver.

sides of the through-holes 7 are so designed as to provide a rigid and o2 0 torsion-proof connection between the hooking and fastening part.

The contact face 6 of the fastening part 6 or rather the shank 5 of the fastening 9 part 3 features claws 10 projecting from the end face 6 which make a certain prefixing to the roof batten possible when the installer presses the shank against a roof batten. The final fixing is by a nail which is indicated by 11. A 25 lateral face of the shank 5 parallel to the insertion direction of the shank 4 of the hooking part 1 features a holding device and guideway for the nail 11. The holding device and the guideway 12 are so arranged that the nail 11 encloses an acute angle with the lateral face of the shank 5 of the fastening part 3. The nail point (at 13) exits from the base surface 6 of the shank 5 facing the roof 3 0 batten in line with the through-holes 7 for the shaft 4 of the hooking part 1 so that an almost moment-free nailing of the shaft 5 to a roof batten is made possible.

In the embodiment the hooking part 1 is formed from a flat metal strip at the top end of which the hook 2 is bent over, whereby along the shaft 4 the necessary 3 5 holes 8 haven been punched out. The fastening part 3 in the embodiment is a moulded plastic part. The design as per invention provides an easy way for securing roof tiles with suitable wind-resisting clamps, whereby it is possible to use one and the same clamp for different heights of the edge or interlocking edge of the tile to be engaged by the hook 2 and for different distances of the hooking area of the roof tile from the roof batten.

The invention is not restricted to the embodiment but variable in many ways within the scope of the disclosure.

All new individual and combined characteristics disclosed in the description and/or drawing are considered an essential part of the invention.
