Description

FIELD OF THE INVENTION

The present invention relates to a roofing device and a method for producing such a roofing device.

TECHNICAL BACKGROUND

Canopies are used for a wide variety of applications. A frequently encountered type of roofing is the so-called terrace roofing.

Although the present invention and the problems on which it is based are described below on the basis of a terrace roofing, they are not limited to this but can be transferred to various types of roofing devices.

Terrace canopies often have a longitudinal beam profile designed as a wall connection profile, which is anchored to a wall with fastening means, for example bolts. Due to structural or local conditions, an installation height of such a wall connection profile can vary. On a side facing away from the wall, the terrace covering is usually stored with a purlin supported by posts. All of these components are usually prefabricated parts that are pre-produced in standard sizes. It is therefore desirable to be able to vary an angle of attack of the rafters during assembly, which results from the assembly height of the wall connection profile and the height of the posts, in order to be simple Way to be able to react to structural or local conditions.

With a variability of the angle of attack of the rafters, there is also the need for variability of the angle of attack of the roof panels or infills, which are usually mounted on the rafters.

The publication US 4,998,389A describes a roof system that is provided with a wall connection. For this purpose, wall connection fittings are provided on a wall connection profile, which have a circular cylindrical recess. A rafter holder has a rafter holder fitting corresponding thereto, which has a circular cylinder which can be received in the recess. Furthermore, the rafter holder fitting has a locking flange. In this way, the rafter holder fitting can be attached and detached from the wall connection fitting in a horizontal position. If the rafter holder fitting is pivoted into an angular position, the locking flange engages under the wall connection fitting, so that the rafter holder is secured in it. A roof panel rests on the rafters here. For sealing purposes, a separate web is provided on the wall connection profile, on which a seal that is applied to the roof panel is provided.

The disadvantage of mounting with such a system is that the angle of the rafters is not completely free to choose, since a minimum inclination is necessary in order to ensure securing by the closure flange. Furthermore, the web or the seal for sealing the roof panel must be designed for the desired angle of attack or adapted to it during assembly.

The applicant has one in the DE 20 2016 005 196 U1 The solution described is provided, which provides an insertion section locally limited in the longitudinal direction on the longitudinal member profile of a roofing device, on which a bearing profile section designed to receive a rafter holder is excluded such that it can be inserted into a gripping section of the rafter holder for assembly. In this way, a positive connection between the longitudinal beam profile and rafter holder can be produced by longitudinal displacement.

When terrace roofing is installed, a longitudinal dimension with which rafter holders of adjacent rafters are spaced apart is determined by the width of the infill, for example in the case of glass by the width of the glass panes. This measure is usually provided with a thermal expansion game and the rafter holder is positioned accordingly in the longitudinal direction. The rafters are then assembled step by step and the infill is measured and used in them. In this process, the manufacturing and calibration tolerances add up disadvantageously along the roof. Accordingly, the dimension of a last infill, which is used last during assembly, must be adapted to the remaining length of the side member profile. For example, the last infill, in particular in the case of glass, the last glass pane and a glass strip securing the pane, may be too short if too little expansion air has been left beforehand. In this case, bridging pieces would have to be used or new parts made. Otherwise the infill, in particular a glazing bead or possibly the last pane, may be too wide if too much expansion air has been left.

SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of specifying an improved roofing device and a method for its production.

Accordingly, it is provided:

• A roofing device, in particular terrace roofing, with: a longitudinal beam profile which is designed for mounting a rafter holder and has a bearing profile section; a rafter holder for holding a rafter on the side member profile, the rafter holder having a wrap-around portion corresponding to the bearing profile portion, which is designed for form-fitting mounting on the bearing profile portion, the side member profile having an insertion portion locally limited in the longitudinal direction, on which the bearing profile portion is so excluded, that it can be inserted into the encircling section of the rafter holder for assembly, the encircling section being designed to be longitudinally displaceable on the bearing profile section and a form fit between the encircling section and the bearing profile section can be produced by longitudinal displacement, and wherein a latching means on the encircling section of the rafter holder and on the bearing profile section of the side member profile a counter-latching means acting in the longitudinal direction offset to the insertion section is provided, which is achieved by longitudinally displacing the encircling section are designed to be engageable with one another on the bearing profile section.
• A method for producing a roofing device according to the invention, comprising the steps of: providing a longitudinal beam profile for receiving a rafter holder, which has a bearing profile section, and a rafter holder for holding a rafter on the longitudinal beam profile, which has a wrap-around section corresponding to the bearing profile section, with the wrap-around section of the Rafters a locking means and on the bearing profile section of the longitudinal beam profile a longitudinally arranged counter-latching means is provided which is offset in the longitudinal direction from the insertion section; Inserting the bearing profile section into the gripping section in the region of an insertion section provided locally delimited in the longitudinal direction on the longitudinal member profile; Producing a positive connection between the encompassing section and the bearing profile section by longitudinally displacing the encompassing section relative to the bearing profile section; and producing a longitudinal securing of the encircling section on the bearing profile section by engaging the latching and counter-latching means by longitudinally displacing the encircling section on the bearing profile section.

The knowledge on which the present invention is based is that the addition of manufacturing and calibration tolerances when mounting a roofing device can be avoided by longitudinally securing rafter holders at predetermined latching sections.

The idea on which the present invention is based is now to provide a latching means on the encircling section of the rafter holder and counter-latching means acting in the longitudinal direction on the bearing profile section of the longitudinal beam profile at predetermined latching sections, which latches automatically when the positive connection is produced by longitudinal displacement engage with each other. In this way, all longitudinal adjustment work is avoided when installing a roofing device. In addition, thermal expansion joints are dimensioned in the factory, so that the previously usual step of measuring a infill with a suitable expansion joint is no longer necessary. In this way, according to the invention, all infills of the roofing device can be provided with the correct dimension from the outset or in the factory, so that in particular no adjustment to a final infill is required.

In summary, according to the invention, a fitter no longer has to worry about the fastening and dimensional accuracy when positioning rafter holders, in particular also no longer about the error-prone measurement of expansion joints. Instead, the necessary expansion air is already specified by the assembly technology according to the invention.

In addition, a fitter does not need to fix the rafter holder, as was previously the case, by additional fastening means on the side member profile. Instead, the correct assembly position, which is already matched to the intended infill, is specified according to the invention by the corresponding prefabrication of the latching and counter-latching means and the longitudinal securing at the correct point is achieved automatically by the engagement of the latching and counter-latching means.

For assembly, the installer therefore only needs to insert the rafter holder on the insertion section and move it in the longitudinal direction until the latching and counter-latching means snap into place. According to the invention, the installation of a roofing device is made possible in a much simpler, safer, faster and less prone to error manner. In particular A very high level of occupational safety is also provided for the assembly, since the rafter holder once used can no longer get out of the longitudinal member profile unintentionally after it has been moved longitudinally.

The longitudinal beam profile can have different configurations, for example it can be designed as a wall connection profile or as a purlin.

Any type of design suitable for holding a rafter on a longitudinal beam profile is to be regarded as a rafter holder.

A gripping section is to be understood as a section of the rafter holder which is suitable for gripping around the bearing profile section. When reaching around, the bearing profile section is gripped at least partially, in particular at least on two opposite sides, in such a way that there is a positive, pivotable coupling of the rafter holder to the longitudinal beam profile.

An insertion section which is locally delimited in the longitudinal direction is to be understood as a locally recessed section which does not extend over the entire length of the side member profile but only over a comparatively small part or section of the length of the side member profile. The width of the insertion section is wide enough to insert the locally excluded bearing profile section into the gripping section of the rafter holder. The insertion section thus has a width which is wider than the gripping section of the rafter holder. For example, it can be a width of the insertion section in the range of one to two times the width of the rafter holder.

The counter-latching means is arranged offset in the longitudinal direction in relation to the insertion section which is locally limited in the longitudinal direction in such a way that sufficient, preferably complete, support of the encircling section on the bearing profile section is ensured.

In addition, the longitudinal member profile is formed in the longitudinal direction in particular with a constant cross-sectional shape. The bearing profile section is, with the exception of the recess and the counter-latching means, a section of the longitudinal beam profile that runs linearly with a constant cross section.

A positive connection is produced in particular by moving the rafter holder in the longitudinal direction of the longitudinal beam profile out of the insertion section, that is to say in particular into an area without a recess in the bearing profile section.

The engagement of the locking means and counter-locking means can be carried out simultaneously with the production of a positive connection. In particular, the counter-locking means can be positioned on the bearing profile section in such a way that the locking and counter-locking means come into engagement with one another when a complete positive fit is achieved. If the latching and counter-latching means are in engagement with one another, the rafter holding is latched or secured in the longitudinal direction on the bearing profile section.

The method for producing the roofing device represents in particular an assembly method or a method for mounting a roofing device.

Advantageous refinements and developments result from the further subclaims and from the description with reference to the figures of the drawing.

According to an advantageous embodiment, the latching and counter-latching means for longitudinal securing of the encompassing section are formed on the bearing profile section. Advantageously, there is therefore no need for additional or manual longitudinal securing of the rafter holder.

According to a preferred embodiment, the latching and counter-latching means are designed to be rotatable relative to one another, so that the engaging section can be pivoted about the longitudinal axis of the bearing profile section in a latched state. In this way, a desired roof pitch can be freely and continuously adjusted.

In one development, the gripping section can be pivoted in a locked state by a predetermined angle about the longitudinal axis of the bearing profile section. In particular, it can be pivoted through an angle which is between 10 ° and 45 °. Such an angle is preferably between 15 ° and 35 °. A particularly preferred angle is between 25 ° and 30 °.

According to a further development, the gripping section can be pivoted in a locked state by a predetermined angular section of a position of the rafter holder relative to the longitudinal beam profile about the longitudinal axis of the bearing profile section. In particular, the pivotability is provided in the case of an angular position of the rafter holder in relation to the longitudinal beam profile between -10 ° and 45 °. Such an angular position is preferably between 0 ° and 35 °. An angular position in the range between 3 ° and 30 ° can be particularly preferred.

According to an advantageous embodiment, the locking and counter-locking means are designed to be detachable by exceeding the predetermined angle. Alternatively or additionally, the latching and counter-latching means are designed to be detachable by exceeding the predetermined angular section. In this way, the engagement between the latching and counter-latching means can advantageously also be released again without destruction, for example for dismantling the roofing device.

According to one embodiment, the locking means and the counter-locking means are formed with a resilient pressure piece and a circumferential groove corresponding thereto. The pressure piece can, for example, be arranged in a threaded bore running transversely to the longitudinal axis in the encompassing section. The circumferential groove can extend over a section of the lateral surface of the bearing profile section. In particular, the circumferential groove describes an angular section around the longitudinal axis of the bearing profile section. In the longitudinal direction, the circumferential groove is preferably formed with a thickness corresponding to the pressure piece.

According to an advantageous development, the circumferential groove terminates with an incline at at least one end. The slope is designed such that the pressure piece can be pressed out of the circumferential groove by releasing the predetermined angle of rotation and / or the predetermined angle section in order to release the latching and counter-latching means. If the pressure piece is formed with a round head, the pressure piece can only be pushed out of the groove to a large extent for loosening and the remaining spring force can be overcome with a longitudinal displacement by means of the round shape. The spring force of the pressure piece advantageously always counteracts the release, so that a certain resistance is provided which avoids unintentional or automatic loosening. Further advantageously, no tools for loosening are required. In addition, the release is made non-destructive.

In a further embodiment, a groove that cuts the bearing profile section secant-like would also be conceivable as a counter-latching means. Advantageously, such a secant-like groove in the case of a cylindrical bearing profile section automatically has a groove base that runs obliquely to the lateral surface, so that there is no need for an additional slope at the outlet of the groove. Of course, it depends on the material thickness or the design of the bearing profile section whether a groove that cuts the bearing profile section like a secant is considered from the point of view of the statics.

According to one embodiment, the latching means is formed with the pressure piece arranged in the encircling section and the counter-latching means is formed with the circumferential groove made in the bearing profile section. The pressure piece can, for example, be screwed into a threaded bore provided in the gripping section. The circumferential groove can, for example, be milled automatically in the area of the bearing profile section. The latching and counter-latching means are thus advantageously easy to manufacture.

According to one embodiment, the counter-latching means is arranged in a latching section of the bearing profile section that predetermines an installation position of the rafter holder in the longitudinal direction. The latching and counter-latching means can be brought into engagement with one another by longitudinally displacing the encompassing section on the bearing profile section from the insertion section to the latching section. In particular, the latching section can be used to achieve a complete form fit be dimensioned around the encompassing section and the bearing profile section and accordingly also has unprocessed sections of the bearing profile section. The dimensioning of the latching section is preferably provided in such a way that the latching and counter-latching means come into engagement with one another when the complete positive locking is achieved.

According to one embodiment, the insertion section is arranged directly next to the latching section. In particular, the latching section borders directly on the insertion section. In this way, the longitudinal displacement required for assembly is advantageously reduced to only the dimension required to produce the desired positive connection.

According to one embodiment, the latching section is assigned two insertion sections which are arranged on both sides next to the latching section. In this way, the installation can be carried out in accordance with the installation situation or accessibility from both sides.

According to an advantageous embodiment, the bearing profile section has a profile which is at least partially round in cross section. The gripping section has a corresponding, at least sectionally round recess. In particular, the bearing profile section is at least partially circular-cylindrical and the recess is likewise at least partially circular-cylindrical. The round design advantageously allows the bearing profile section and the encompassing section to slide against one another, so that an angle of attack can be set.

According to one embodiment, the encompassing section has a bore, in particular a threaded bore, projecting into the recess, which is round at least in sections. In the hole the locking means can be attached. In particular, it can be a pressure piece which is resiliently received in a sleeve provided with an external thread. In this way, the latching means can be positioned in a desired position on the wrap-around section during the prefabrication of a roofing device. The positioning need not be changed particularly advantageously because of the lack of training during assembly. In particular, this represents a great advantage compared to a threaded pin that was previously often used for fixation.

According to an advantageous embodiment, the bearing profile section can be encompassed at a circumferential angle of greater than 180 °. In particular, it is designed to encompass at a circumferential angle of at least 270 °, preferably 280 ° to 300 °. In this way, a large pivoting area between the longitudinal beam profile and rafter holder is advantageously made possible.

According to a preferred embodiment, the encompassing section is designed to encompass the bearing profile section at a circumferential angle greater than 180 °. In this way, a form fit with the bearing profile section is made possible only by the shape of the encircling section. In an advantageous embodiment, the circumferential angle is greater than 200 °, preferably between 210 ° and 260 °, particularly preferably between 230 ° and 250 °.

According to a particularly preferred embodiment, the bearing profile section can be encompassed in the longitudinal direction away from the insertion section by the encircling section in such a way that the rafter holder can be pivoted into a positive and into a negative position relative to the longitudinal member profile while maintaining the positive fit. Positive employment is understood to mean an employment in which a rafter supported on the rafter holder runs downwards from the longitudinal beam profile. Accordingly, a negative position means a position in which a rafter supported on the rafter holder runs upwards from the longitudinal beam profile. Advantageously, no structural changes to the load-bearing components need be made for both types of employment.

According to one embodiment, the swivel range of the employment is at least 0 ° to + 30 °. Swivel ranges from 0 ° to + 45 ° are also conceivable. In this way, conventional angles of attack are advantageously covered by the swivel area, in particular for terrace roofing.

According to one embodiment, the side member profile is designed as a wall connection profile. In the assembled state, the position can be adjusted relative to a wall. A wall is understood to mean any type of structure suitable for attaching the wall connection profile. It can be, for example, a brick wall, a wooden wall, a facade, a frame, a framework or the like. In particular, the wall is a vertical wall. However, an inclined wall or facade can also be used.

According to a further embodiment, the side member profile is designed as a purlin profile. In the assembled state, the position can be adjusted relative to it. In particular, the purlin profile can be provided or designed in the form of a ridge purlin. In this way, the roofing device can advantageously also be installed without a wall connection. In particular, the purlin is aligned with a vertical, so that the angle of attack can be aligned with respect to the vertical.

According to one embodiment, the side member profile has a bearing profile section on both sides. In this case, opposite rafters can be accommodated in the side member profile. This version is provided in particular in the case of a longitudinal beam profile designed as a ridge purlin. In this way, a roof can advantageously be realized with a common longitudinal beam profile on two opposite sides of the longitudinal beam profile. In particular, such a longitudinal beam profile with a bearing profile section on both sides can be two interconnected one-sided longitudinal beam profiles. For example, two longitudinal beam profiles provided for wall connection can be connected to one another on their wall sides, so that a common profile with bearing profile sections on both sides is created. The variety of components is advantageously reduced in this way, so that production is simplified.

In an advantageous embodiment, a purlin, in particular in the form of a purlin, is provided on an end of the rafter opposite the rafter holder. The purlin has a circular bearing extension. In particular, it is designed in the form of a circular cylindrical profile section. The rafters have a corresponding receiving extension, which is in particular in the form of a claw with a circular cylindrical section-shaped recess. The receiving extension is designed to grip around the circular bearing extension. In particular, the mounting of the circular bearing extension with the receiving extension takes place with a positive connection, preferably by longitudinally displacing the receiving extension on the round bearing extension. A purely articulated connection of the purlin to the savings, which is also displaceable, is thus advantageously created, so that flexible adjustment of the different angles of the rafters is also guaranteed here.

According to an advantageous embodiment of the method for producing the roofing device, after the longitudinal displacement to adjust a roof pitch in the locked state, a positive, longitudinally secured pivoting of the rafter holder relative to the longitudinal member profile is carried out. In this way, a desired setting angle of the rafters can advantageously be set relative to the longitudinal beam profile, in particular in a predetermined swivel range with positive or negative setting, in the locked state. In spite of the pivoting, the longitudinal positioning can advantageously remain secured.

In a further embodiment, a step of the stationary mounting of the side member profile is provided before the bearing profile section is inserted into the encompassing section. The longitudinal displacement is carried out accordingly by moving the rafter holder along the longitudinal beam profile. Advantageously, only the rafter holder needs to be manipulated in this way, so that the assembly is simplified.

The above refinements and developments can, if appropriate, be combined with one another as desired. In particular, all features of a roofing device can be transferred to a method for producing the roofing device, and vice versa. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments, which are not explicitly mentioned. In particular, the person skilled in the art will also consider individual aspects as improvements or additions add to the respective basic form of the present invention.

The accompanying figures of the drawing are intended to provide a further understanding of the embodiments of the invention. They illustrate embodiments and, in connection with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the advantages mentioned result from the drawings. The elements of the drawings are not necessarily shown to scale with respect to one another.

In the figures of the drawing, elements, features and components that are the same, have the same function and have the same effect — unless otherwise stated — are each provided with the same reference numerals.

DESCRIPTION OF EMBODIMENTS

Fig. 1 shows a roofing device 1 before assembly.

The roofing device 1 has a longitudinal beam profile 2 designed as a wall connection profile, a rafter 5 and a rafter holder 3 designed and fastened, for example screwed, to the longitudinal beam profile 2 to hold or support the rafter 5.

The longitudinal beam profile 2 has a bearing profile section 4 designed for mounting the rafter holder 3. The bearing profile section 4 is formed with a sectionally round shape, here for example a hollow circular cylinder shape, which is connected in one piece to a wall connection area of the wall connection profile 2 via support struts 16. The bearing profile section 4 is accordingly preferably formed in one piece with the other parts of the wall connection profile 2.

The longitudinal beam profile 2 is designed, for example, as an extruded profile. In particular, it contains aluminum. Other extrudable materials, for example plastics, would alternatively or additionally also be conceivable.

The longitudinal beam profile 2 has, for example, two insertion sections 7, which are provided on both sides next to a latching section 15. It is therefore possible to insert a rafter holder on both sides. Of course, a single or one-sided insertion section 7 would also suffice for the function of the insertion.

In these insertion sections 7, the bearing profile section 4 is locally excluded, here, for example, with a secant-like recess 17. In a further embodiment, a groove cutting the bearing profile section in the manner of a secant would also be conceivable as counter-latching means. Such advantageously has In the case of a cylindrical bearing profile section, the secant-like cutting groove automatically has a groove base that runs obliquely to the lateral surface, so that there is no need for a slope at the outlet of the groove. Of course, it depends on the material thickness or the design of the bearing profile section whether a groove that cuts the bearing profile section like a secant is considered from the point of view of the statics.

Fig. 2 shows a cross-sectional view of a rafter holder 3.

The rafter holder 3 has a gripping section 6 with a recess 18 corresponding to the bearing profile section 4. Accordingly, the illustrated embodiment is, for example, a circular cylindrical recess 18.

The gripping section 6 with its recess 18 is designed for form-fitting storage on the bearing profile section 4. In the assembled state, it encompasses the bearing profile section 4 to the extent that a pivotable positive connection is provided.

To secure the rafter holder lengthways, a latching means 8 is arranged on the encompassing section 6. Corresponding to this is the in Fig. 1 Bearing profile section 4 of the longitudinal beam profile 2 shown is provided in the region of a latching section 15 in the region of a latching section 15, in the longitudinal direction offset to the insertion section 7 and acting in the longitudinal direction. The latching and counter-latching means 8, 9 are designed such that they can be brought into engagement with one another by longitudinally displacing the encompassing section 6 on the bearing profile section 4, so that a longitudinal securing of the encompassing section 6 on the bearing profile section 4 is made possible, which is achieved by the engagement.

In addition, the latching and counter-latching means 8, 9 are designed to be rotatable relative to one another despite an engagement, that is to say in a latched state. The gripping section 6 can thus still be pivoted about the longitudinal axis of the bearing profile section 4 in a locked state of the latching and counter-latching means 8, 9.

Figure 3A shows a cross-sectional view through an insertion section 7 of the longitudinal beam profile 2 and the rafter holder 3 of the roofing device 1 according to FIG Fig. 1 .

The bearing profile section 4 is inserted here in the area of the insertion section 7 into the gripping section 6 of the rafter holder 3. From the in Fig. 1 shown position, the rafter holder 6 for this purpose or for mounting in the region of the recessed insertion section 7 with the recess 18 is pushed onto the bearing profile section 4, which is made possible by the locally provided recess 15. The locking means 8, which in one Fig. 2 shown relaxed state protrudes into the recess 18 is biased.

The pretension usually does not have to be applied manually when the latching means is pretensioned upward or obliquely upward, as in the exemplary embodiment shown, since the weight of the rafter 5 connected to the rafter holder 3 detaches the gripping section 6 against the spring force of the latching means 8 when it is inserted presses down.

In the position shown, the rafter holder 3 can now be moved along the longitudinal beam profile 2 or in the longitudinal direction on the bearing profile section 4.

Figure 3B shows an enlarged cross-sectional view of the canopy device according to Figure 3A in the area of the encompassing section.

The secant-like recess 17 of the insertion section 7 is shown in detail here. In the embodiment shown, the recess 17 clearly does not penetrate the material of the bearing profile section 4. Accordingly, it is a pocket-like recess 17.

The shape of the bearing profile section 4 which is changed locally by means of the recess 17 in the region of the insertion section 7 enables the bearing profile section 4 to be inserted here into the encompassing section 6 of the rafter holder 3.

In further embodiments, the insertion section 7 can also be formed with a different shape of the recess 17. The recess 17 can also be crescent-shaped, for example. The function of the secant-like recess 17 is the same as that of a crescent-shaped recess. Due to its straight course, the secant-like recess is comparatively easier to produce, for example by means of a straight crossing of a conventional milling cutter with a cylindrical shape.

Furthermore, the bias of the locking means 8 can be seen here, which in comparison to the relaxed state in Fig. 2 is evidently pressed resiliently into the gripping section 6 and is thus preloaded.

Figure 4A shows a cross-sectional view through a latching section 15 of the longitudinal beam profile 2 and the rafter holder 3 of the roofing device 1.

The position shown here is based on the position Figure 3A taken by longitudinally moving the rafter holder 3. The rafter holder 3 is accordingly shifted longitudinally along the bearing profile section 4 from the insertion section 7 to the latching section 15.

As can be seen in this view, the encompassing section 6 now encompasses the bearing profile section 4 in an angular range greater than 180 °, so that there is a positive fit. In addition, due to the round shape of the bearing profile section 4 and the recess 8 of the encompassing section 6, the rafter holder 3 can be pivoted relative to the longitudinal beam profile 2. In this position, the gripping section 6 of the rafter holder 3 is thus connected to the bearing profile section 4 of the side member profile 2 in a form-fitting and pivotable manner.

In addition, the locking and counter-locking means 8, 9 are in engagement with one another in this position.

Figure 4B shows a detailed view of the canopy device 1 according to Figure 4A in the area of the encompassing section.

The latching means 8 is formed with a resilient pressure piece 12 arranged in the encompassing section 6, and the counter-latching means 9 is formed with a circumferential groove 13 made in the bearing profile section 4. When sliding longitudinally, this slides accordingly 3A and 3B pressure piece pressed into the encompassing section 6 along the surface of the bearing profile section 4 and snaps into the circumferential groove 13 due to its spring preload when the circumferential groove 13 is reached. The circumferential groove 13 thus limits the longitudinal displacement, so that the rafter holder 3 is secured longitudinally.

The rafter holder 3 can be pivoted relative to the longitudinal beam profile 2 while maintaining the positive fit in a pivoting range of an angle 10 about the longitudinal axis of the bearing profile section into different angles of attack. This is achieved in that the bearing profile section 4 is designed to encompass a larger circumferential angle than the encompassing section 6 encompasses the bearing profile section 4.

For example, here a circumferential angle in which the bearing profile section 4 can be gripped is more than 270 °. Furthermore, a circumferential angle in which the encompassing section 6 encompasses the bearing profile section 4 is more than 180 °. The result is a theoretical swivel range, which is obtained from the difference between these circumferential angles and can be, for example, 60 °. In fact, however, transition radii and / or further sections of the longitudinal beam profile 2 and the rafter holder 3 limit the swivel range, so that a usable swivel range is smaller. The circumferential groove 13 forming the counter-locking means 9 then extends over this usable pivoting range.

In a locked state, the gripping section 6 can therefore be pivoted about an angle of rotation 10 predetermined with the circumferential groove about the longitudinal axis of the bearing profile section 4. In the illustrated embodiment, the angle 10 is 27 °, for example. In other embodiments, of course, differently sized swivel ranges are possible. For example, the angle 10 can be in the range from 10 ° to 45 °, preferably in the range from 15 ° to 35 °, particularly preferably in the range from 25 ° to 30 °.

Thus, in a locked state, various positions of the rafter holder 3 can be assumed relative to the longitudinal beam profile 2 by pivoting the rafter holder 3. In the exemplary embodiment shown, the Range of a possible angular position 11 of the rafter holder 3 to the longitudinal beam profile 4 in a locked state between 3 ° and 30 °. In other embodiments, of course, differently dimensioned areas of a possible angular position 11 are possible, for example from 0 ° to 45 °. In theory, negative areas of the angular position 11 are also conceivable.

Figure 5A shows a cross-sectional view of the canopy device 1 according to Figure 4A in a level state.

A position of the rafter holder 3 and the rafter 5 relative to the longitudinal beam profile 2 is accordingly 0 ° here. Since, in the case of a mounted roofing device, at least a small angle of inclination is generally provided in order to ensure that precipitation runs off, this is a position which is only relevant for assembly or disassembly.

According to the invention, such a position can be adopted to release the longitudinal securing of the encompassing section 6 of the rafter holder 3 on the bearing profile section 4 of the longitudinal beam profile 2. The locking and counter-locking means 8, 9 are thus designed to be detachable by exceeding the predetermined angle of rotation 10 or the predetermined angle section 11.

In the embodiment shown, the rafter holder is adjusted beyond the horizontal position shown into a negative angle of attack. The latching and counter-latching means 8, 9 are designed and designed such that the engagement is thereby released. Accordingly, longitudinal securing is no longer present and the rafter holder 3 can be longitudinally displaced back to the insertion section 7 and there be removed. The canopy device can thus not only be assembled in a simple manner, but also disassembled in a simple manner without tools.

Figure 5B shows an enlarged view of the canopy device 1 according to Figure 5A in the area of the locking and counter-locking means 8, 9.

It can be seen in this illustration that the circumferential groove 13 ends at its upper end with an incline 14. The latching connection of the latching and counter-latching means 8, 9 can thus be released by pushing the pressure piece 12 back into the encompassing section 6 by crossing the horizontal position and in this way. can be pressed out of the circumferential groove 13. At the end of the slope 14, the pressure piece 12 thus rests on the outer surface of the bearing profile section 4 and can accordingly slide again longitudinally along the bearing profile section 4 when the rafter holder 3 is displaced longitudinally.

Furthermore, the pressure piece 12 is formed with a rounded head in the embodiment shown. It can now be pressed out in the horizontal or 0 ° position shown, in which it is already largely pushed out of the circumferential groove 13, by the rounded shape with a little effort, for example a rubber hammer blow, directly in the longitudinal direction of the bearing profile section 4.

Fig. 6 shows a perspective view of a latching section 15.

The latching section 15 has a width which corresponds at least to the width of the encompassing section 6 of the rafter holder 3 and is largely formed with the profile of the bearing profile section 4. The counter-latching means 9, here in the form of the circumferential groove 13, is arranged within the latching section 15, preferably in the center.

The position of the latching section 15 and the counter-latching means 9 determines an installation position of the rafter holder 3 in the longitudinal direction of the bearing profile section 4.

In the illustrated embodiment, two latching sections 7 are assigned to latching section 15, which are arranged on both sides directly next to latching section 15.

The latching and counter-latching means 8, 9 can be brought into engagement with one another starting from both insertion sections 7 by longitudinally displacing the encompassing section 6 inserted into the bearing profile section 4 from the respective insertion section 7 to the latching section 15.

Fig. 7 shows a front view of a longitudinal position of a rafter holder 3 in the locked state.

The rafter holder 3 is arranged in the center of the bearing profile section 4 between the two insertion sections 7 in accordance with the arrangement of the latching section 15.

Fig. 8 shows a perspective view of a terrace roof with wall connection.

The terrace roofing is an embodiment of the roofing device 1, in which the longitudinal beam profile 2 is designed as a wall connection profile fastened to a wall 20.

In the illustrated embodiment, the roofing device 1 has a plurality of parallel rafters 5, which are held on the side member profile 2. A infill 24 runs between the rafters 5, which is designed as a glass infill, for example. Alternatively or additionally, an infill 24 can also be provided in the form of different types of panels, for example so-called double-wall panels or opaque panels.

At an end of the rafters 5 opposite the longitudinal beam profile 2, they are supported via a pivot bearing on a purlin 19 running parallel to the longitudinal beam profile 2. An angle of attack of the rafters 5 is positive relative to the wall 20 or the wall connection profile 2 fixed thereon, so that the roofing device 1 falls from the side member profile 2 towards the purlin 19. The purlin 19 thus forms a foot purlin here.

The purlin 19 is supported by two posts 21 attached to it at the ends, which are anchored in a floor 22.

At the end of the rafters 5 facing away from the longitudinal beam profile 2, a gutter 23 running transversely to the rafters 5 or parallel to the purlin 19 is also provided, with an associated drain pipe for receiving and removing precipitation.

According to the invention, a terrace covering of this type can be installed without measuring the infill 24 in relation to the spacing of the rafters 5. Instead, the rafters 3 are inserted with the factory pre-assembled locking means 8 on the factory-made insertion sections 7, shifted longitudinally along the bearing profile section 4 and brought into engagement with counter-locking means 9 on the likewise pre-manufactured locking sections 15 and so on longitudinally secured. The distance between the latching sections 15 provided for the individual rafters 5 and the dimensions of the infills 24 are pre-assembled in such a way that expansion joints 29 which are ideally dimensioned in the factory are predetermined for the infill 24. Accordingly, the dimension of all the infills 24 fits directly to the positioning of the latched rafter holder 3. In particular, the dimensions of a last infill 24 used need not be adjusted.

In addition, the terrace covering with the in the DE 20 2016 005 196 U1 further elements described in detail.

Fig. 9 shows a perspective view of a terrace roof with ridge purlin.

In contrast to the embodiment according to Fig. 8 the roofing device 1 is not designed to be connected to a wall, but rather is free-standing and sloping on both sides.

The longitudinal beam profile 2 is accordingly designed as a ridge purlin and has a bearing profile section 4 on both sides, as well as all other elements of the longitudinal beam profile 2 described in relation to the preceding figures. The longitudinal beam profile 2, which is designed as a ridge purlin, is articulated by means of a pivot bearing on a purlin 19 'which runs parallel to the longitudinal beam profile 2 and is supported at the end on middle posts 21'.

Purlins 19 and gutters 23, which are arranged as foot purlins and are provided on both sides of the end of the rafters 5 facing away from the longitudinal beam profile 2, are provided in the same way as in FIG Fig. 8 are trained. Fig. 10 shows a perspective sectional view of a roofing device 1 according to Fig. 1 with infill 24.

The infill 24 is placed with an expansion joint 29 on a respective glass gasket 26 inserted into the receiving sections of a support profile 25 inserted between the rafter holders 3 and the rafter 5 and held by means of profiles 28 fastened in fastening grooves 27.

Fig. 11 shows a longitudinal sectional view through a terrace roof in the area of infills 24.

The rafters 5 are also shown in cross section here. An expansion joint 29 is provided between the rafters 5 and the infills 24. According to the invention, these expansion joints 29 are optimally guaranteed by the predetermined positioning of the rafter holder 3 and thus the rafters 5 in the longitudinal direction of the longitudinal beam profile 2 without additional measurement. A last infill 24 'in the assembly order therefore does not need to be shortened in order to correctly set an expansion joint 29' in the assembly order.

Although the present invention has been completely described above on the basis of preferred exemplary embodiments, it is not restricted to this, but rather can be modified in a variety of ways as defined in the claims.

For example, instead of a circumferential groove that only extends at a constant depth on the lateral surface, a groove that cuts the bearing profile section in the manner of a secant would also be conceivable as counter-latching means.
