DE10052979C1 - Snow hook - Google Patents

Abstract

The hook is made from flat material with a hook (12) at one end for hanging in a roof pantile and a bracket (14) at the other end to catch the snow. Between the hook and bracket in side view there is an upwardly directed curvature (16) The hook is made from spring elastic material

Description

The invention relates to a snow catch hook made of flat material for a Roof tiles covered sloping roof, with the snow catch hook on one Roof tile can be placed and hung on the upper edge of the roof tile at one end a hook bent towards the bottom and at the other End has an upward angled support.

Such a snow guard hook is from the utility model DE 78 00 625 U1 known. Such snow catch hooks are on one Sloping roof attached to hold snow and ice so that the finish a roof avalanche is prevented. The disadvantage of the known Snow catcher is that in a relatively short version, which is the angled support near the covered portion of the with the Snow-covered roof tile lies by the prop dissipated force is introduced approximately in the middle of the roof tile, so that the roof tile is subjected to an increased breaking load.

A better derivation of the force is achieved if the snow catch hook is like this long that the support in the area of the overlapping section the roof tile lies so that the force covered over the one below Roof tile is transferred to the roof batten carrying it. The disadvantage of one such a long snow catch hook is that it is in the snow-free time tends to rattle in strong wind or storm.

The object of the present invention is to provide a snow guard hook, which the favorable derivation of the force towards the roof batten without bending stress Roof tile allows it to be easy to manufacture and in snow-free condition doesn't rattle even in storm.

The object is achieved in that the snow catch hook has an upward curvature in the side view. Under Curvature in the sense of the invention is not just an arched curvature understand, but also a kink between the hook and the Support lies.  

It is essential that the snow catch hook is unloaded on it supporting roof tile lies hollow between the hook and the support. In on the When installed in the roof, the snow guard hook is affected by the weight of the roof tile covering it is bent flat, so that the support having end section on the roof tile carrying the snow guard hook is pressed on. It has been shown that a force of approximately 0.15 kp is sufficient to prevent rattling in storm.

To set a defined preload, it is advantageous if the Snow guard hook is made of resilient material.

In a further development of the invention, the snow catch hook can also be inserted into the arched watercourse of a profiled roof tile can be installed if the flat material is adjacent to the end bent in the shape of a hook Section with a width of less than 20 mm, advantageously of less than 17 mm. This narrow section lies in the built-in Condition on the roof in the covered area of the roof tile and lifts the roof tile only very little. Would the covered section would be carried out in full width, depending on the profile used Roof tile different versions of the snow guard hook required, which have an adapted transverse curvature in this section.

The angled support can absorb high forces if it has one Stiffening, which is essentially triangular in side view executed and in the area of the bend with the snow guard hook connected is.

A particularly high stability of the support is achieved with simple means, if additional stiffening in the area of the support and the stiffening Longitudinal beads are provided. Inside the Stiffening triangle can also be a plate arranged in the longitudinal direction be provided.

In the drawing is a preferred embodiment of the invention shown, which is explained in more detail below.  

It shows

Fig. 1 shows a snow catch hook according to the invention in side view and

Fig. 2 shows the snow catch hook from Fig. 1 in plan view.

The snow guard hook 10 made of flat material has a hook 12 pointing to the underside at one end. At the other end an upwardly angled support 14 is arranged. Between the hook 12 and the support 14 , the snow guard hook 10 has an upward curvature 16 .

The angled support 14 has a stiffening 18 which is essentially triangular and is connected to the snow catch hook 10 in the region of the angled portion 20 .

In Fig. 2, which shows the snow catcher 10 in plan view, it can be seen that the snow catcher has a portion 22 which is adjacent to the end with the hook 12 and is less than 20 mm wide. In the area of the support 14 and the stiffening 18 , beads 24 , 26 extending in the longitudinal direction are provided.
