SI22301A - Clip for fixing parts of roof covering - Google Patents

Abstract

For the purpose to design a clip for fixing parts of a roof covering to the truss, especially for fixing roof tiles, roof bricks or ridge tiles, where the clip (1) consists essentially of a rectangular flat sheet metal cutting (1') which is fixable on its first area (2) to the truss and on its second area (3) wears a longitudinal notch (4) opened towards the free end, and where two end areas (5, 6), formed due to the mentioned longitudinal notch (4), are directed apart and curved, namely such a clip which could be manufactured at a favourable price and simply in spite of machine directioning apart its end areas without producing any projection which would exceed the thickness of the sheet metal, it has been proposed according to the invention that the sheet metal cutting within the area of the longitudinal notch (4) shall comprise an impressed area (7), where by impressing the area (7), the directioning apart of the end areas (5, 6) is achieved.

Description

The invention relates to a buckle for attaching roofing parts to a roof, in particular for attaching roof tiles, bricks or ridges, wherein the buckle consists essentially of a rectangular sheet-like cutout that attaches to the roof in the first area and extends towards the second zone. the open end of the sheet notch has an open longitudinal notch, whereby thanks to said notches, the formed end regions are open and curved.

Such buckles are covered by the prior art. They are made of sheet metal, preferably aluminum sheet. Up to now, it has been customary to manufacture such staples from rectangular sheet metal, with the second sheet area being notched. The notched area is opened with the help of a suitable forming tool and the free ends curved, forming the holding elements for holding the roofing or the like. Such clips are particularly useful for ridges. Due to the method of manufacture, a projection occurs at the transition from the first area to the second area due to the transformation. The disadvantage of this protrusion is that during the laying of the roof or ridge, this protrusion is an obstacle to the roof or ridge.

Based on the aforementioned state of the art, the invention is based on the problem of how to design this type of clip, which could be inexpensively and easily fabricated, despite machine extrusion of end areas without any projection exceeding the thickness of the sheet.

As a solution to this problem, it is proposed that the sheet notch in the region of the longitudinal notch comprises an imprinted area, and thanks to said area, the openness of the end areas is achieved.

By forming an imprinted area in the longitudinal notch area, the material is cut in the longitudinal notch area by tilting so that the edges of the sheet notch in the notch area face each other, causing the end areas to open. This does not alter the sheet metal outside the dimensions of the flat sheet metal in such a way as to allow the normal laying of ordinary roof tiles or ridges.

Preferably, the imprinted area is located at the end of the longitudinal notch, with the end facing towards the first area.

It is particularly preferred that the imprinted area is located at the end of the longitudinal notch at which the end is projected towards the first area, with the longitudinal notch extending over the entire imprinted area until the end of the imprinted area facing the first end area.

Thanks to this arrangement, the desired ends can be stretched as desired in the manner described previously.

In addition, it is preferred that the impression area is circular in shape.

This results in a uniform tear-off of the material, which contributes to the desired dissipation.

It can also be preferred that the diameter of the embossed area corresponds to about half the width of the sheet cutout.

It is particularly preferred that the thickness of the sheet metal cutout material is less in the impression area than in the remaining areas of the sheet metal cutout.

It may be assumed that the depth of the impression area corresponds to about half the thickness of the sheet metal material.

Depending on the thickness of the stamped area, it is possible to determine the degree of unfolding to open the intended ends. The greater the depth, the greater the openness of the ends.

Preferably, due to the imprinted area, the tilting of the tilting notch is substantially transverse with respect to the longitudinal notch, with the layer of tilting material determining the degree of opening of the end regions.

It is further preferred that the bending curvature line, by means of a longitudinal notch of the separate free end areas, be located approximately at the edge of the embossed area facing the free end areas.

The curvature of the free end areas can be performed after the imprinted area has been constructed. However, it is also possible to bend the end areas before embossing the embossed area. In both cases, the desired intersection is achieved by notching separate ends. Preferably, the end regions are V-shaped open areas.

From the point of view of manufacturing technology, it is advantageous if the indentation forming the recess is made from one side in the sheet metal.

For the same reason, it is preferred that the imprinted area be formed on the side from which the curved ends are located.

The staple according to the invention is made in such a way that first a rectangular sheet metal cut is cut, and the cut can also be done by removing a narrow strip of sheet in the area. This may be followed by a bending of the loose ends, or alternatively, a stamped area is made using a stamping matrix before the bending of the loose ends. By means of said embossing die, the material of the sheet notch is deposited in the region in which the longitudinal notch is arranged, so that the two notches separated by the notch are detached from each other and moved to the open position. With the pre-curved buckles, the free ends are finally formed. In the case of a flat sheet notch, where the embossing is first made, the bending of the ends is followed.

The following is a detailed explanation of an embodiment of the invention in the accompanying drawing.

In doing so, they show

FIG. 1 individual steps of making a buckle according to the invention;

FIG. 2 to 4 clip according to the invention in various aspects;

FIG. 5 to 7, however, a well-known fastener for attaching the roof covering in various aspects.

The prior art fastens the fastening of roofing parts to the roof as shown in FIG. 5 to 7. Such clips are intended primarily for attaching the ridges to the roof. The buckle 10 is made of a substantially rectangular sheet metal recess which is fixed to the roof in the first region 11, wherein the first region 11 may also comprise a hole for the passage of the fixing nail or the like.

The sheet notch in the second region 12 comprises an open longitudinal notch toward the free end of the sheet notch, with the end regions 13 formed by the longitudinal notch being open and curved. The spreading is done in such a way that the tool acts on the cutout area 11 (in the area 14) near the adjacent area 12. This transforms the area, which results in the area 13 being expanded. otherwise, a straight sheet cutout in the region 14, such as a junction at 11, is transformed substantially beyond the starting dimensions. This protuberance is a barrier to the laying of roofing parts, especially for the laying of ridges.

The invention is explained in more detail in FIG. 1 to 4. In this case, too, this is a clip for attaching the roof covering to the roof. This clip 1 typically consists of a substantially straight sheet metal cutout shown in FIG. 1 above and marked with Γ. This flat sheet cutout Γ is fixed to the roof with the first area 2, and this area may comprise e.g. holes for passage of fasteners. In the second area 3, the sheet notch comprises a longitudinal notch 4. In the case 1, thanks to the notches, the end regions 5, 6 formed are open to the other side of the other and curved in the same direction from the opposite direction. Due to the formation of the opening, the sheet notch in the longitudinal notch area comprises an imprinted area 7, whereby the end areas 5, 6 are Thanks to this imprinted area. In the present embodiment, a sheet notch as shown in FIG. 1, top left, first curves as shown in FIG. 1 right above. The sheet cut is then actuated by an embossing die 8, thus forming an imprinted region 7. The direction of the action of the imprinting force is indicated by F. In the present embodiment, the imprinted region 7 is provided at the end of a longitudinal notch 4 at its end toward the first end region 2, facing end . The longitudinal notch 4 extends over the entire impression area 7 and beyond the end of this impression area 7 to the cutout area 2. The embossed area is preferably circularly shaped, wherein the diameter of the embossed area 7 corresponds to about half the thickness of the sheet cutout. The thickness of the sheet metal cutout material is smaller in the impression area 7 than in the remaining cutout areas. The depth of the embossed area is freely selectable, but preferably the depth corresponds to approximately half the thickness of the sheet metal material. Due to the embossed area 7, the tilting material of the sheet notch is substantially transverse with respect to the longitudinal direction of the longitudinal notch 4, wherein the layer of the tilting material determines the degree of unfolding of the end zones 5, 6. The bending line 9 in bending the free ends 5, 6, separated by longitudinal notch, lies approximately in the marginal area of the imprinted region 7, facing the free end regions 3. As can be seen in particular in FIG. 1 to the left below, the end regions 5, 6 are spread out in the shape of a letter V. The embossed area 7 forming the recess is made from the top of the sheet notch. During the transformation, the canopy is supported on the underside on the underside. The embossed area 7 is preferably made on the side from which the ends 5,6 are curved.

The invention therefore provides an extremely functional imaginative and inexpensive clamp that can be manufactured with high precision in terms of reproducibility, avoiding defects in the projection of sheet metal cutout that may be interfering with laying and arranging while attaching roofing components. .

The invention is not limited to the embodiment, but is obviously available in several versions.

Therefore, all the individual and combined characteristics contained in the description and / or in the drawing must be taken into account as per the invention.
