Description

The present invention relates to a snow catcher for a rooftop roofed pitched roof according to the preamble of claim 1 and a method of attaching a snow guarding hook according to the preamble of claim 11.

Snow hooks of the type mentioned are mounted on roof tiles covered sloped roofs to prevent an avalanche-like slippage of snow that has accumulated on the sloping roof.

Such snow catch hooks are known in the prior art in various embodiments.

DE 40 09 164 A1 discloses, for example, a snow catcher for a roof tile covered sloped roof having a first section for securing the snow guard hook, a support section adjoining the first section, a support section adjoining the support section, and a second section for catching snow. The first section for fixing the snow catch hook is bent like a hook and engages in the intended installed condition of the snow guard hook on the rear surface of the roof formed Dachpfannenfalz, which is held on a battens, and the Traglattung itself. The support section is in the intended installed condition of the snow guard hook on the top of that roof tile, on which the first section of the snow guard hook is hung. The support portion extends upwardly at an acute angle from the support portion and supports the second snow catching portion extending downwardly from the support portion toward the top of the support portion and connecting the support portion to the support portion.

Such a structure of a snow catch hook has some disadvantages. For example, in different types of roof tiles, the height or thickness of the upper fold, which is set on the battens, is different pronounced. This must be taken into account when choosing the size of the hook-shaped first section for determining the snow catch hook, with the result that the first section must be designed differently for different roof tile types. Thus, different snow guards are required for different types of roof tiles, which must be manufactured and stored individually, which is not desirable. Another disadvantage is that the support portion of the snow catch hook must be made relatively long to lead out the second section for catching snow below the roof tile above. This requires an increased cost of material for the support section, so that the snow catch hooks are correspondingly expensive. In addition, the fastening of the snow guard hook on a roof tiles already roofed is quite cumbersome because a plurality of roof tiles must be covered to guide the hook-shaped first portion of the snow guard around the top rabbet of a tile and the underlying battens.

Further snow catch hooks with similar structure are z. In DE 100 52 979 C1 . AT 255 102 B and DE 78 00 625 U1 disclosed. These snow catch hooks have the above-mentioned disadvantages. Also known are snow catch hook according to EP 0 389 438 A1 . DE 196 47 528 C1 and DE 25 31 220 C2 ,

Also from EP 0 377 407 A1 a snow holder is known. This has an integrated trained plastic part with a snow retaining part and a support part and a sliding and fixable in part headband. A subsequent to the snow retaining part paragraph and the horizontal part and a paragraph of the retaining clip form two the lower end of the tile pliers enclosing arms. The upper portion of the vertical part of the bracket is provided with a nose, with a spring surrounding the upper portion and the nose. Parallel to the vertical part of the retaining bracket is provided in the part of a grid plate with grid teeth. To mount the snow holder, the bracket is inserted into a guide channel arranged in the part, wherein the spring engages between two raster teeth.

Several variants of the snow holder shown consist of several parts that must be assembled during assembly on the roof. Furthermore disclosed EP 0 377 407 A1 several snow holders, which are integrally formed as (injection) casting.

With this in mind, it is an object of the present invention to provide an improved snow catcher which requires little material, is suitable for various types of roof tiles, incurs low cost, enables easy assembly, and at least partially overcomes the aforementioned problems of the prior art.

To achieve this object, the present invention provides a snow catcher for a roof tile covered sloped roof according to claim 1. The dependent claims relate to individual embodiments of the present invention.

A snow guard for a roof tile covered sloped roof according to the present invention includes a first section for securing the snow guard hook and a second section for intercepting snow. The first section is designed such that it can be suspended in the intended installed state of the snow guard hook on a lower region of a roof tile, in particular on Fußzufalz a tile. Furthermore, the first portion is hook-shaped and surrounds and / or engages behind the Fußfalz the roof tile in the intended installed condition of the roof pan at least partially from below and is non-positively and / or positively engaged with the Fußfalz the roof tile into engagement. In this case, the snow catch hook on a support portion which rests in the intended installed condition of the snow guard hook on another roof tile. The snow catch hook also has a clamping portion which is supported in the intended installed condition of the snow guard on the roof tile on which the first section is mounted, wherein the clamping portion is resilient and in the intended installed condition of the snow guard hook with a predetermined clamping force against a top of Roof pan presses. According to the invention, the snow catch hook with all its sections, including possible fixing elements, is produced in one piece from a band-shaped metal element while performing bending and cutting or punching operations.

A significant advantage of this embodiment of the snow catcher according to the invention is that the formation of the first portion for fixing the snow catch hook is substantially independent of the formation of the Fußfalzes the roof tile. Another advantage is that a support portion compared to the prior art can be made much shorter, since only the distance between the Fußfalz and the lower edge of the roof tile is to bridge to the second section for catching snow in the intended installed state of the snow catch hook below the roof tile to which the snow catch hook is fixed to position. Accordingly, material can be saved for the formation of the support section.

For arranging the snow guard hook according to the invention on a roof already covered with roof tiles, it is only necessary to lift that roof tile to which the snow guard hook is to be suspended in such a way that the first section for fixing the snow guard hook can be pushed and hooked under the foot rebate of the raised roof tile , The removal of a plurality of roof tiles is accordingly no longer necessary, which significantly reduces the workload. In addition, the weight exerted by the snow collected at the snow gun is distributed among a plurality of tiles, namely, the one to which the snow guard is hung and the roof tile positioned thereunder. In this way, the roof tiles are significantly relieved.

In order to ensure a secure hold of the snow guard hook according to the invention on a roof tile, surrounds and / or engages behind the Fußfalz the roof tile at least partially from below the first section for fixing the snow guard hook in the intended installed condition of the snow guard. In this case, the first portion of the snow guard hook is non-positively and / or positively engaged with the Fußfalz the roof tile in engagement. Suitably, the first portion is formed substantially hook-shaped, so that the hook can be mounted quickly and easily. The handling is extremely simple.

Furthermore, the snow catch hook comprises a support section, which rests on a further roof tile in the intended installed state of the snow catch hook, so that a part of the weight of the held by the snow catch snow is taken up by the further roof tile.

In addition, the snow catcher according to the invention comprises a clamping portion, which is supported in the intended installed condition of the snow guard hook on the top of that roof tile, on which the first portion of the snow guard hook is mounted. This clamping portion forms an additional safeguard that prevents the snow catch hook from accidentally coming off the associated roof tile. The clamping portion is resilient and / or clamped and presses in the intended installed condition of the snow guard hook with a predetermined clamping force against an upper side of the corresponding roof tile. Accordingly, a clamping arrangement is produced in which the roof tile between the clamping portion and the first portion and the support portion is clamped.

The position of the clamping portion relative to the first portion is advantageously fixable, wherein the fixation preferably takes place via a fixing element.

The snow catcher according to the present invention preferably has a substantially U-shaped configuration with two opposing leg portions and a connecting portion connecting the leg portions, wherein a leg portion of the first portion to Setting the snow hook and the other leg portion forms the second clamping portion for trapping snow. The connection region is preferably designed such that it supports the second section for catching snow. The leg portions are preferably inclined to each other.

The fixing member for fixing the position of the clamping portion relative to the first portion is formed according to an embodiment as a one of a leg portion cut and bent in the direction of the other leg portion fixing. The fixing section preferably engages with its free end through an opening provided in the other leg region, which is formed, for example, like a slot. The free end of the fixing section advantageously has a hook-like protruding projection which serves to fix the free end of the fixing section to the opening provided in the leg region.

The opening provided in the leg portion may have an extended opening portion for passing the hook-like projecting projection. In addition or alternatively, at least the free end of the fixing section can be made twistable, wherein the hook-like projecting projection in the twisted position of the fixing section can be passed through the opening provided in the leg region, but not in the non-twisted position.

In the previously listed advantageous or preferred embodiments of the snow catcher according to the invention this is integrally formed with all its sections, including the fixing, whereby in particular the assembly of the snow guard hook is facilitated on a roof tile.

In a method of attaching a snow guard hook to a roof tile covered sloped roof, having a first section for securing the snow guard hook to a roof tile, and having at least one further snow trapping section, the invention contemplates that the snow guard hook contacts the first section a lower portion of the roof tile is hung.

By this measure, the installation of snow catcher on pitched roofs compared to conventional methods is greatly simplified, because to hook the hook no longer numerous roof tiles must first be removed and then placed back on the roof battens. Rather, the hook is simply with its first section at the bottom of the tile, d. H. hung at the front edge or Fußfalz. This area is accessible without difficulty, so that the assembly takes little time.

The invention further provides that the roof tile is raised for hanging the first portion with its lower portion opposite a further roof tile arranged thereunder. The removal of the roof tile or even several roof tiles is not necessary. Rather, it is sufficient to slightly raise the roof tile to which the hook is to be hooked, with its lower edge and hang the hook with its first section there.

Appropriately, the first portion of the hook is suspended from below in the lower region or in the Fußfalz the roof tile. This is easily accessible without problems.

So that the hook on the roof finds a support, it is intended to hang him with a support section on the other roof tile. The latter is directly below the roof tile, to which the hook is hung.

After installation, the first section of the snow catch hook engages behind the Fußfalz the roof tile. The support section lies flat on the adjacent roof tile. Already the weight of the roof tile, which holds the hook, secures this against falling, because the roof pan pushes the first section against the further arranged below roof tile. In order to achieve an additional security, the invention further provides that the hook is fixed to the roof tile to which it is suspended.

For this purpose, it is provided that the hook is clamped to the roof tile, for example with a spring leg, which is supported after hanging the first section in the lower region of the roof tile on this.

To hook in the hook, the spring leg is simply bent. As a result, the hook can be easily hung with its first section in the Fußfalz the roof tile. As soon as the hook has reached its intended installed state, the spring leg exerts a force on the roof tile, so that the hook can not be detached from the roof tile. The hook thus encloses the roof tile with the first section and the spring leg like a clamp that secures the snow catch hook on the roof.

In order to further increase safety, in a further embodiment it is additionally or alternatively provided that the first section and the spring leg are in the installed state of the hook be secured relative to each other. For this purpose, a fixing element is preferably provided, which fixes the first portion and the spring leg relative to each other. Neither the spring leg nor the first hook portion can then be released from the roof tile.

Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:

1 a perspective view of a first embodiment of a snow catch hook according to the present invention;

2 a perspective view of the snow catch hook according to 1 in the intended condition installed;

3 a side view of the in the 1 and 2 illustrated snow catch hook in the intended installed condition; and

4 a perspective view of a second embodiment of the snow catch hook according to the present invention.

Like reference numerals refer to similar components below.

1 shows a perspective view of a first embodiment of a snow catch hook 10 according to the present invention. The snow catch hook 10 is for one with roof tiles 11 . 15 Covered tilted roof formed and serves to capture snow, which may have collected on the roof or on the sloping roof surface. It is made in one piece from a band-shaped metal element made of spring steel. This is preferably stainless and is processed solely by bending operations, which has a very favorable effect on the production costs.

The hook 10 is according to the invention for hanging on a Fußfalz 11a a roof tile 11 trained, ie it is not - as conventionally - hung on the top Dachpfannenfalz or on the battens, but at the bottom or front end 11a the roof tile 11 , For this purpose, the metal element comprises a first section 12 to set the snow catch hook 10 , this first section 12 in the intended condition of the snow guard hook 10 behind the Fußfalz 11a the roof tile 11 can be hung, as it is in the 2 and 3 is shown.

To the first section 12 closes a support section 14 in the present case substantially perpendicular to the first section 12 extends. The support section 14 serves as a support on an upper side of another roof tile 15 under the roof tile 11 is arranged as it is in the 2 and 3 is shown.

From the support section 14 extends a support section 16 at an acute angle α upwards. To the support section 16 closes a second section 18 on, extending from the support section 16 at an acute angle β downwards. The second section 18 serves in the intended installed condition of the snow catch hook 10 to catch snow. The support section 16 supports the second section 18 , To the second section 18 closes a clamping section 20 at, which at an angle γ to the support section 14 is inclined.

The clamping section 20 serves to apply a clamping force in the bestimmungemäß arranged state of the snow guard hook 10 , referring to the 2 and 3 will be explained in more detail. To the clamping section 20 closes an upwardly extending end portion 22 on, which avoids that the clamping section 20 with a sharp edge on the roof tile 11 supported. Furthermore, the end section facilitates 22 the assembly of the snow catch hook 10 on the roof tile 11 ,

The 2 and 3 show the snow catcher 10 according to the first embodiment of the present invention in the intended installed state, wherein 2 a perspective view and 3 a side view, partially in section, represents.

For installation of in 1 shown snow catch hook 10 on a roof covering is the roof tile 11 at the bottom 11a , ie at her Fußfalz, raised. At the same time, the clamping portion 20 of the hook 10 in the upward direction of the storage section 14 so far spread out that the hook 10 with his first section 12 under the Fußfalz 11a pushed and can be hung there. Then the Aufspreizkraft is released and the hook 10 with its storage section 14 on the below the roof tile 11 arranged roof tile 15 stored. The clamping section 20 moves back towards the support section 14 until it is with a linear support area 24 in the transition between the clamping section 20 and the end section 22 is formed on top of the roof tile 11 hangs up. The snow catch hook 10 now takes the in 2 and 3 shown position, ie the first section 12 engages behind the Fußfalz 11a the top roof tile 11 while the rest section 14 flat on the roof tile 15 supported. The second section 18 and the clamping portion 20 form a spring leg, with its support area 24 on the roof tile 11 presses and so on the hook 10 secure in his position. The snow catch hook 10 can therefore no longer fall by mistake. No tools or other aids are required for the entire assembly. Also setting the hook 10 on the roof is done without any additional fasteners.

Darmit the snow catch hook 10 is always securely fixed, the distance a between the support area 24 of the clamping section 20 and one through the rest section 14 defined level in the 1 illustrated state in which the snow catch hook 10 is not intended, smaller than the distance b between the support surface of the lower tile 15 on which the support section 14 in the orderly arranged state comes to rest, and the bearing surface of the upper roof tile 11 on which the support area 24 of the clamping section 20 comes in the intended condition of concern.

The snow catch hook 10 must therefore be spread during assembly at least by the difference b - a to reach the installation position. By this spreading a clamping force is generated, with which the support area 24 of the clamping section 20 against the top of the roof tile 11 pushes so that next to the Fußfalz 11a the roof tile 11 poignant first section 12 the snow catch hook 10 An additional safeguard against accidental slipping or loosening of the snow catch hook 10 from the roof tile 11 is produced. Due to the size of the difference b - a can also adjust the clamping force with which the clamping section 20 the hook 10 guaranteed.

This is the snow catcher 10 always safe on the roof tile 11 held. The second section 18 and the clamping portion 20 are in the in the 2 and 3 illustrated condition of the snow guard hook 10 suitable for catching snow accumulating on the roof, in order to prevent it from slipping off like an avalanche. The support section 14 lies flat on the below the roof tile 11 positioned roof tile 15 on, making a part of the sections 18 and 20 acting weight forces of snow the roof tile 15 loaded. The weight of the snow is correspondingly on the roof tiles 11 and 15 distributed.

4 show a perspective view of another embodiment of a snow catch hook 30 according to the present invention.

Just like in the 1 to 3 illustrated snow catcher 10 has the snow catcher 30 a first (hook) section 12 , a rest section 14 , a support section 16 , a second section 18 , a clamping section 20 , an end section 22 and a support area 24 on, wherein the arrangement of these sections relative to each other corresponds to that in the 1 to 3 is shown, which is why not discussed in detail.

To the position of the clamping section 20 relative to the first section 12 or to the support section 14 to fix, has the snow catch hook 30 via a fixing element 32 that from the rest section 14 the snow catch hook 10 cut or punched out and from this upwards in the direction of the clamping section 20 is bent. The free end of the fixing element 32 is with a hook-like protruding projection 34 provided, which may be formed substantially T-shaped. This lead 34 serves to fix the fixing element 32 in one in the clamping section 20 trained slot-shaped opening 36 which is also cut out or punched out.

To the projection 34 of the fixing element 32 through the opening 36 of the clamping section 20 to pass and then the lead 34 at the opening 36 determine is the fuser 32 formed torsionally, so that the projection 34 in the twisted position of the fixing element 32 through the opening 36 can be performed while in the non-twisted position of the fixing 32 not through the opening 36 fits. Alternatively, at the opening 36 an extended insertion area for the lead 34 be provided, for example in the manner of a keyhole to the projection 34 in the opening 36 to be able to introduce, which is not shown. In this case, it is not necessary, the fixing element 32 trainable.

With the fixing element 32 can in a simple way the distance a between the support area 24 of the clamping section 20 and the through the support section 14 defined level can be set and fixed, so that the hook 10 always safe on the roof tile 11 is fixed. Preferably, one also selects here the distance a smaller than the distance b, so that the clamping portion 20 the hook 10 on the roof tile 11 can secure.

The assembly is similar to that in the 1 to 3 illustrated hooks 10 , The support area 14 and the clamping portion 20 are spread open, leaving the hook 10 with his hook section 12 in the Fußfalz 11a the roof tile 11 can be hung. Then the hook is 30 with its support area 14 on the roof tile 15 hung up and the clamping section 20 on the top of the roof tile above 11 lowered. Finally, the lead 34 of the fixing element 32 through the opening 36 stuck through it and secured it. The fixing element 32 now pulls the clamping section 20 against the support area 14 so that's the catch 30 how a clamp contracts. The hook section 12 can no longer feel the Fußfalz 11a to solve. The hook 30 is on the roof tile 11 secured.

The in 4 illustrated snow catcher 30 according to the present invention is made in one piece from a band-shaped metal element performing bending and cutting or punching operations, which has a favorable effect on the production costs. Again, neither for mounting nor for fixing the hook 10 additional aids needed.
