Description

The invention relates to an articulated arm awning with a rotatably mounted cloth shaft, from which a cloth is unwound, the front end of which is fastened to an extension profile carried by articulated arms.

Such awnings are known.

The problem with such awnings, which are freely clamped and whose extension profile is supported by articulated arms, is that they are deflected under wind load, ie that the extension profile and thus the entire clamped awning moves out under an attacking wind load from the rest position and upwards or can turn down. This can endanger people under the awning. This problem is to be addressed by providing supports on the extension profile.

From the DE 10 2005 040 755 A1 an articulated arm awning is known in which the extension profile rests in the extended state on collapsible support rods, which are supported against the ground and resiliently compressible together. This is done by overcoming the spring force through the weight of rainwater in the awning and compressing the supports together to drain the water. The disadvantage of this arrangement is that the awning uncontrolled down is deflected and thus persons under the awning could be endangered.

From the DE 92 07 428 U1 A high-rise safety device for articulated-arm awnings is known, which is realized in that cables or chains which are attached to the extension profile are hooked into hooks arranged on the floor. A particular disadvantage of this arrangement is that while a high impact of the awning is prevented under wind load, however, when attacking a large wind load, the entire awning can be damaged or even destroyed.

From the DE 20 2009 001 663 U1 an awning is known, are arranged in the support posts on the Ausfahrprofil the Gelenkarmwnise, wherein the bottom end of the support pile is provided with a latch member and further provided in the bottom and provided with a receptacle for receiving the latch part support is provided so that upon extension of the awning The support posts provided on the extension profile automatically enter into the receptacles to be attached to the floor and are locked therein.

A disadvantage of such an arrangement is that the wind loads and shear forces acting on the Ausfahrprofil by the arrangement of columns on the awning structure must be taken and they can not be compensated because only a high-impact protection is realized by the intended support piles, respectively, an uncontrolled swinging down the Awning is prevented. However, it can not be prevented that the awning is damaged when attacking excessive wind loads and excessive shear forces.

The object of the invention is to further develop an awning of the type mentioned that it is reliably secured even when attacking wind loads against uncontrolled deflection from the rest position, and it should also be ensured that the overall system higher security against Damage when attacking wind loads or yourself rainwater collected on the awning fabric against damage.

This object is achieved by an awning according to claim 1. Advantageous developments of the invention are specified in the subclaims.

Particularly advantageous in the articulated arm awning according to the invention with a rotatably mounted fabric shaft from which a cloth is fastened, whose front end is fastened to an extension profile carried by articulated arms, it is that at least one support fixed to the bottom is arranged against the upper free end of the extension profile at fully extended awning moves, wherein at the Ausfahrprofil or the upper end of the support at least one magnet is arranged, which forms a releasable magnetic connection with a corresponding magnetic counterpart on the other part with fully extended awning.

The magnetic counterpart can be a magnetisable metal or else another, reversely poled magnet, whereby the magnetic holding force can be increased and adapted to the requirements of the holding force of the magnetic connection to be generated.

Characterized in that at least one bottom-mounted support is arranged and a magnetic attachment of the extension profile at the upper free end of the support, resulting from the prior art, a significantly increased diagonal stiffness of the entire system and it can be better absorbed and balanced by wind loads shear forces become.

The invention can thus be retrofitted in a particularly advantageous manner with existing articulated arm awnings by only one or more magnets or magnetic counterparts are arranged on the Ausfahrprofil and the bottom side one or more supports are mounted, against the upper free end of the extension profile moves at fully extended awning and in turn carries at its upper end either one or more magnets or corresponding magnetic counterparts. As a result, existing systems can be retrofitted in an easy way.

Preferably, a positive mold on the Ausfahrprofil or the upper end of the support moves into a negative mold on the other part with fully extended awning, so that a positive connection is formed, wherein the magnet and the corresponding magnetic counterpart are arranged such that a magnetic force at full in the Negative form retracted positive shape is formed.

Due to the positive connection between the positive mold and negative form a protection of the Ausfahrprofils in the vertical direction parallel to the course of the vertical support and horizontal right and left direction is created parallel to the course of the extension profile. The details on the right and left refer to the extension direction of the extension profile of the awning.

A securing of the Ausfahrprofils in horizontal or nearly horizontal retraction is thereby realized by the magnetic force, since the magnet is arranged such that the magnetic adhesion with fully retracted into the negative mold positive shape, i. is realized with fully extended Ausfahrprofil. The retraction direction can be inclined to the horizontal. Since articulated arm awnings are usually not exactly horizontal but slightly inclined downwards to be arranged on a building.

Particularly preferably, a projection on the Ausfahrprofil or the upper end of the support is arranged, which moves into a cup-shaped receptacle on the other part, so that a positive connection between the projection and the receptacle is formed, wherein at the front end of the projection and / or on the ground the recording is arranged a magnet.

By a cup-shaped, in particular tapering in the direction of the bottom of the receptacle shape of the receptacle as a negative mold a safe retraction of the counterpart is ensured in the form of a projection as a positive mold. It is thus achieved on the one hand by the positive connection between the projection and recording and also by the magnetic force fit a secure hold of the extension profile on the one or more supports.

The extension profile is then secured in the fully extended position by a combination of positive engagement with a traction against deflections from the rest position.

In a particularly preferred embodiment, two supports are arranged, which are positioned such that the ends of the Ausfahrprofils each run against the upper end of a support and the supports form lateral boundaries.

When the awning is extended, the articulated awning or other free-standing awning is thereby supported on the one hand against wind and rain loads, and further the two provided support piles form lateral boundaries in the front region, so that overall the atmosphere of a pergola-like enclosure of the patio area is created.

Furthermore, the arrangement of two supports, each supporting the ends of the Ausfahrprofiles, an optimized static of the entire arrangement.

Preferably, each support at the upper free end on a corresponding to the outer contour of the Ausfahrprofile receiving area.

As a result, a reliable retraction of the extension profile is ensured in the corresponding receptacle at the upper end of the support and it is created a visually appealing overall arrangement.

Particularly preferably, each support at the upper free end on a corresponding to the outer contour of the Ausfahrprofile receiving area, wherein in the receiving area a plurality of magnets and / or magnetic counterparts are arranged in different angular positions with respect to the vertical.

Magnetic connections have the property that the magnetic holding force perpendicular to the contact surface between magnet and counterpart is maximum. In the pulling direction parallel to the contact surface, however, the holding force is only 40% of the maximum perpendicular thereto occurring magnetic holding force.

By arranging a plurality of magnets and corresponding magnetic counterparts in the contact area between the extension profile on the one hand and support on the other hand, wherein the contact surfaces between the magnets and counterparts have different angular positions to the vertical, an optimal holding force for fixing the Ausfahrprofils can be realized on the supports, in particular a in horizontal direction other, for example, smaller, holding force can be realized, as in the vertical direction.

As a result, a high impact of the awning in the attack of a wind load is prevented, a release in the retraction direction, however, allows. Further, it is possible to align the resultant of the respective maximum holding force of the various magnets at an arbitrary angle. The resultant results from the vector addition of the individual maximum holding forces, which in turn are perpendicular to the respective contact surfaces of the magnets.

Further, the magnets may be the same or different dimensions in the arrangement of multiple magnets to realize the desired holding forces in the vertical direction and horizontal direction.

As a result, the holding force in the retraction of the awning can be adjusted so that this one hand by an electric motor drive the Cloth wave is overcome, and on the other hand, when excessive wind loads occur an automatic release of the magnetic connections to prevent damage to the awning.

It can also be used several identical magnets in different angular position. In its simplest embodiment, the magnetic connection between the extension profile and the support has only one magnet and a corresponding magnetic counterpart.

If only a single magnet with a horizontally arranged contact surface is arranged in each contact region between the extension profile and the support, the required shearing force corresponding to the required tensile force on the awning fabric for releasing the magnetic connection in the retraction direction is thus approximately 40% of the maximum, as explained above magnetic holding force in the vertical direction.

Particularly preferably, the holding force of the magnet or magnets is selected so that it is overcome by the transmitted by an electric drive motor to the electric motor driven extension and retraction of the awning on the fabric shaft torque and the resulting tensile force on the awning fabric and the extension profile in the retraction direction and upon retraction of the awning, the magnetic connection of the magnet (s) with the magnetic counterpart (s) automatically releases.

Such an arrangement ensures that the awning is not damaged when the electric motor for retracting the awning is actuated in magnetic connection of Ausfahrprofil and supports. It is now common to equip awnings with electric motors for extending and retracting the awning, in particular, these are preferably controlled and actuated by means of a radio remote control. However, a manual release of the connection is not required before a retraction process.

Characterized in that the holding force of the / the magnet is selected so that the magnetic fixation of the extension profile automatically triggers and is released, If the awning drive is operated to retract the awning, damage to the awning is reliably prevented.

Furthermore, it is particularly advantageous in such an automatic releasing fixation when exceeding a certain tensile force on the connection of magnets and counterparts that even when attacking excessive wind loads, the awning is not damaged, but then, when a wind load on the awning fabric attacks, from this automatically results in a tensile force on the connection in the retraction direction and the extension profile can move away as a result of this attacking force and the automatic release of the magnetic connection of the free end of the supports.

As a result, damage to the awning is effectively prevented.

In a further embodiment, a wind sensor is arranged, which automatically actuates the motor upon detection of the exceeding of a limit value for the wind speed and triggers a retraction of the awning.

In a preferred embodiment, the supports are mounted on the bottom side on elastic damping elements for compensating and damping wind-induced vibrations and the like.

The supports can thus be mounted on damping elements such as rubber plates or the like to dampen vibrations that occur, as observed when attacking wind loads.

The awning preferably has a volute shaft arranged in or on the extension profile, from which a valance can be unwound vertically downwards, in particular a volute shaft driven by means of an electric motor.

By such a valance can be created in an advantageous manner, a front screen and a front end of the covered with the awning patio area.

Preferably, two supports are arranged, whose distance corresponds to the width of a arranged in or on the Ausfahrprofil valance, wherein in the supports vertical guides are integrated, in which an extension profile of the valance is guided laterally.

By such guides, which are formed as well as known roller shutter guides, such a valance respectively the Ausfahrprofil of the valance can be guided laterally so that it remains in the desired position even when light wind occurs and forms a front optical termination of the covered by the awning terrace area ,

The supports preferably have receptacles for attaching or suspending screen elements and / or wall elements.

Such recordings may be formed by fastening elements or recesses or the like in or on the support profiles.

As a result, wall elements can be suspended or clamped between the supports. In particular, from a wall of the house to which the awning is fastened starting side screens are unrolled / clamped, the front extension profile is hung in the front area of corresponding receptacles on the side supports.

As a result, lateral boundaries and privacy can be realized.

Preferably, the supports are telescopic and variable by means of extensions in length and fixed in the selected length.

As a result, various lengths of the supports can be realized in the modular principle in order to adapt the awning according to the invention to the respective dimensional requirements with regard to the installation conditions, In particular, to be able to adapt columns for retrofitting to existing awnings.

Two embodiments of the invention are illustrated in the figures and are explained in more detail below. Show it:

FIG. 1

A perspective view of a first embodiment of an awning according to the invention;

FIG. 2

FIG. 3

a section through the extension profile of an awning and the receiving area at the upper end of a support post of a second embodiment in the fully extended state.

In the figures, identical components and components are provided with identical reference numerals.

In FIG. 1 is an overall perspective view of an awning 1 according to the invention, which is mounted on a building wall, not shown. The awning 1 has an awning housing 2, in which a cloth shaft is rotatably mounted, from which the cloth 3 can be unwound. The awning 1 is an articulated arm awning. The canvas shaft is driven by an electric motor to extend and retract the awning. The awning 1 thus has an electric motor for driving the cloth shaft in the extension and retraction direction.

The front end of the awning fabric 3 is attached to an extension profile 4, which is attached to the front ends of the hinge arms 9 not visible in this perspective.

In fully extended condition as in FIG. 1 illustrated the extension profile 4 moves against two bottom-mounted support posts. 5

The support posts 5 are permanently mounted on the bottom side and remain free even when the awning 1 is retracted.

The distance between the support posts 5 from each other corresponds to the width of the awning 1 and thus forms lateral boundary posts. The free ends of the support posts 5 have contoured receiving areas, which correspond to the outer contour of the extension profile 4 of the awning 1.

As in FIG. 1 can be seen, a valance shaft is arranged in the extension profile 4 of the awning 1, of which a valance 6 is vertically extendable down. The front end of the valance 6 is fastened to a valance extension profile 7. The valance extension profile 7 is guided laterally in corresponding vertical grooves in the support posts 5.

Furthermore, the support posts 5 receiving elements, can be mounted in the side shielding elements 8. The privacy elements 8 are unwound from wall mounted rollers and hung in the front of the corresponding receptacles on the support post 5. Thus, the screening elements 8 form a lateral conclusion of the covered by the awning 1 and shaded terrace.

The awning 1 is actuated by an electric motor by means of a radio remote control, i. the roller tube rotatably mounted in the awning housing 2 is driven by an electric motor in the extension direction or retraction direction.

The arranged in the extension profile 4 Volantwelle is also operated by means of a radio remote control and driven by an electric motor. For this purpose, a further electric motor is arranged as Volantwellenmotor in the extension profile 4. As a result of the arrangement of the two supporting piles 5 in the front region, a front and lateral termination of the terrace area covered by the awning 1 is thus formed.

In the extended state of the awning 1, the extension profile 4 moves against the upper free ends of the support posts 5 and is fixed by means of the magnets 10, 11, as shown in FIG FIG. 2 is shown. FIG. 2 shows a section through the Ausfahrprofil 4 of the awning 1 and the receiving area at the upper end of a support post 5 in the fully extended state according to Fig. 1 ,

The support 5 is formed by a vertical mast, which can be mounted on the bottom side by means of a plate on the terrace floor. The extension profile 4 is arranged at the front ends of the articulated arms 9 of the awning 1 and is supported by these. In a piping on the extension profile 4, the front end of the cloth 3 of the awning 1 is mounted.

Arranged on the extension profile 4 are a plurality of magnets 10, 11 which form magnetic connections with corresponding magnetic counterparts 12, 13 at the upper end of the support posts 5. The receiving area of the support post 5 corresponds to the outer contour of the extension profile 4 of the awning.

In the contact area a plurality of magnets 10, 11 and their corresponding magnetic counterparts 12, 13 are arranged, wherein these have different angular positions with respect to the vertical direction.

Magnetic connections have the property that the magnetic holding force perpendicular to the contact surface between magnet and counterpart is maximum. In the pulling direction parallel to the contact surface, however, the holding force is only 40% of the maximum perpendicular thereto occurring magnetic holding force.

By arranging a plurality of magnets 10, 11 and corresponding magnetic counterparts 12, 13 in the contact area between the extension profile. 4 and support 5, wherein the contact surfaces between the magnets 10, 11 and counterparts 12, 13 have different angles to the vertical, an optimal holding force for fixing the Ausfahrprofils 4 can be realized on the supports 5.

Furthermore, the magnets 10, 11 may be dimensioned differently to realize the desired holding forces in the vertical direction and horizontal direction. In the illustrated embodiment, the tilted contact magnet 11 is smaller than the magnet 10 whose contact surface is horizontal, so that the magnetic holding force of this magnet 10 is maximum in the vertical direction. Characterized that the magnet 11 is selected smaller with tilted against the horizontal contact surface and thereby has a smaller maximum magnetic holding force, the holding force in retraction of the awning 1 can be adjusted so that this is overcome on the one hand by the electric motor drive the tissue wave, and on the other hand If too large wind loads occur, automatic loosening of the magnetic connections 10 - 12 and 11 - 13 takes place.

However, it is also possible to use a plurality of equally strong magnets in different angular positions. In its simplest embodiment, the magnetic connection between the extension profile 4 and the support 5 has only one magnet and a corresponding magnetic counterpart.

In the in FIG. 2 illustrated embodiment, magnets 10, 11 are arranged on the extension profile 4, wherein in the receiving area of the support 5, the corresponding counterparts 12, 13 are arranged. However, this arrangement can also be reversed or alternating with respect to the arrangement of magnet and counterpart. It can also be arranged more than two magnets.

In FIG. 3 a second embodiment of the invention is shown. FIG. 3 shows a section through the extension profile 4 of the awning 1 and the receiving area at the upper end of a support post 5 of the second embodiment in the fully extended state.

The basic structure of the articulated arm awning 1 corresponds to the structure in accordance with this second embodiment FIG. 2 ,

In the extended state of the awning 1, the extension profile 4 moves against the upper free ends of the support posts 5 and is fixed by means of the magnets 21, 22, as shown in FIG FIG. 3 is shown. FIG. 3 shows a section through the extension profile 4 of the awning 1 and the receiving area at the upper end of a support post 5 of this second embodiment in the fully extended state.

The support 5 is formed by a vertical mast, which is mounted on the bottom side by means of a plate on the terrace floor. The extension profile 4 is arranged at the front ends of the articulated arms 9 of the awning 1 and is supported by these. In a piping on the extension profile 4, the front end of the cloth 3 of the awning 1 is mounted.

In the extension front side 4 projections 23 are arranged on the extension profile, which retract into corresponding cup-shaped receptacles 24 at the upper free end of the support 5. In the variant shown in section according to FIG. 3 only one of the two end supports 5 and the connection of positive mold 23 and negative mold 24 is visible.

By acting as a positive projection 23 on the Ausfahrprofil 4 of the awning 1 and effective as a corresponding negative mold receptacle 24 a positive connection is realized, which counteracts a deflection of the Ausfahrprofils 4 upwards, downwards and into the image plane or out of the image plane and the Extension profile secures.

Against the retraction of the awning 1 is effective magnetic force by the two magnets 21, 22. The first magnet 21 is attached to the tip of the projection 23. The counterpart to the first magnet 21 forming second magnet 22 is attached to the bottom of the cup-shaped receptacle 24 of the support 5. When fully retracted into the receptacle 24 projection 23 there is a magnetic closure between the two Magnets 21, 22. To retract the awning, the magnetic adhesion between the magnets 21, 22 is overcome. For this purpose, the magnets 21, 22 are dimensioned such that the torque generated by the drive motor of the awning 1, which exerts a tensile force against the magnetic connection of the magnets 21, 22 by transmission over the awning fabric 3 on the Ausfahrprofil 4 is sufficient to the magnets 21, 22 to separate, ie to overcome the magnetic holding force, and retract the awning.

Even in the event that too great a wind load on the awning fabric 3 attacks and this deflects from its rest position, the magnetic connection dissolves. This happens because the cloth 3 bulges under wind load and thereby a tensile force is exerted in the retraction on the Ausfahrprofil 4. Too much wind load results in a correspondingly strong buckling of the cloth 3, which in turn leads to an increased tensile force in the retraction direction on the extension profile 4. As a result, solves the magnetic connection between the magnets 21, 22 and damage to the awning 1 by a wind overload is prevented. With decreasing wind, the cloth 3 is relieved and the projection 23 moves back into the receptacle 24 a. In fully retracted position of the positive mold 23 in the negative mold 24, it then comes again to the magnetic closure between the magnets 21, 22 and the extension profile 4 is again secured in the extended position against unwanted movements.
