Abstract

A folding awning has a plurality of support profiles arranged parallel to one another, which are displaceably guided in a first guide. Between adjacent support profiles a cloth section is arranged in each case. At least one of the support profiles is driven by a drive device and movable along the first guide. Between adjacent support profiles a spacer device is arranged, which permits a change in the mutual distance of the adjacent support profiles between a pushed together position in which the support profiles are immediately adjacent, and an exploded position in which the support profiles are arranged at a predetermined mutual distance. The spacer device is engageable with a second guide, wherein the spacer device acts as a spacer when engaging with the second guide and prevents a change in the mutual distance of the adjacent support profiles.

Description

The invention relates to a folding awning with a plurality of mutually parallel support profiles, which are guided displaceably in a first guide, wherein between adjacent support sections each a cloth section is arranged, wherein at least one of the support profiles is driven by a drive device and along the first guide is movable and wherein between adjacent support profiles, a spacer device is arranged, which allows a change in the mutual distance of the adjacent support profiles between a collapsed position in which the support profiles immediately adjacent to each other, and an exploded position in which the support profiles are arranged at a predetermined mutual distance.

A folding awning of the type mentioned is in the EP 2 284 330 B1 described. The folded awning shown there has two spaced apart parallel longitudinal members, each having a first guide. Between the two side rails extend several parallel to each other extending support profiles, which are slidably inserted with their ends in the first guide. Between adjacent support profiles each extending a portion of an awning fabric, so that the intermediate space formed between the two adjacent support profiles is covered and spanned in the exploded position of the cloth section.

If the folding awning is not needed, it is moved into the pushed together position in which the support profiles are arranged directly next to one another in a pack and hanging between adjacent support sections cloth sections hang down. To extend the folding awning, the first of the plurality of support profiles is moved by means of a drive device, for example by means of a manual crank or by means of an electric motor along the first guide. As soon as the 1st support profile has reached a predetermined distance from the following support profile, the next support profile is taken over the cloth section stretched between these two support profiles. This process continues until all supporting profiles are pulled apart and arranged between adjacent support sections cloth sections are at least loosely clamped.

The retraction of the folding awning is done in a corresponding manner in the reverse direction. By means of the drive device, the 1st support profile along the 1st guide is moved in the direction of the adjacent support profile. The arranged between these two support sections cloth section hanging loose and the driven 1st support section comes with the adjacent support section in contact and takes this in his further movement. Also the following ones Support profiles are taken in the further movement of the first driven support profile until again the support profile stack is formed on one side of the first guides.

Since the folding awning also serves as protection against rain, the rainwater accumulating on the clamped cloth sections is discharged into a rain gutter formed below the first guide on the side rail and removed therefrom. The gutter is due to the tightness to be ensured at a small distance below the cloth sections positioned. As a result, when the folding awning is retracted, the cloth sections grind along the gutter, which leads to severe wear of the cloth sections. In addition, there is the problem that the gutter can become dirty over time and this dirt can be transferred to the cloth sections as they grind over the gutter. This is very disadvantageous aesthetically.

According to the EP 2 284 330 B1 adjacent support profiles are additionally connected to each other via a spacer device. The spacer device is a bipartite linkage, wherein each linkage member is pivotally connected at its one end to the associated support profile and at its opposite end to an intermediate piece, wherein the intermediate piece is suspended by a spring in the cloth portion. This is to ensure that the tissue section is held by the spring in a V-shaped configuration to enhance the drainage of rainwater on the top of the tissue section. However, this has the disadvantage that the cloth sections with the retraction of the awning with a relatively large spring force grind along the gutter, whereby the aforementioned problems are exacerbated.

The invention has for its object to provide a folding awning of the type mentioned, in which the aforementioned problems are avoided and excessive sagging of the cloth sections during retraction and extension of the awning is prevented.

This object is achieved with a folding awning with the features of claim 1. It is provided that the spacer device can be brought into engagement with a second guide, the spacer device being forfeited as a spacer when engaging the second guide and preventing a change in the mutual spacing of the adjacent support profiles.

According to the invention it is assumed from the basic idea to keep the support profiles during retraction and preferably also when extending the folding awning over a long distance at a predetermined mutual distance in which the located between the support sections cloth section is stretched or at least only sags to a small extent. As long as the support profiles are kept at this distance, it is reliably avoided that the cloth section located between them comes into contact with the gutter below. Only at the beginning of the extension movement and at the end of the retraction movement of the folding awning effective between the support profiles spacer is released, ie he no longer acts as a spacer and does not hold the support profiles at a predetermined distance, but it is now possible, the support profiles from the collapsed support profile Package or deduct this push together. To achieve this, the second guide is provided, which is brought into engagement with the spacer device.

In the retracted initial position, the support profiles are in the collapsed state and form a support profile package. The tissue sections located between the support profiles hang loosely down each in the form of a loop. By means of the drive device, the first support profile is then moved along the first guide, whereby it is removed from the subsequent support profile until the tissue section located between these two support profiles is tensioned and entrains the subsequent support profile. In this position, or shortly thereafter, the spacer device located between these two support profiles engages the second guide and remains in engagement with this second guide until the folding awning is extended. The same thing happens with the spacing devices arranged between the further adjacent support profiles.

When the folding awning is retracted, the 1st driven support profile is moved in the direction of the adjacent support profile. The spacer device that engages the second guide also acts as a spacer and prevents the mutual spacing of the support profiles from being changed. The driven 1st support profile thus pushes the other support profiles at a distance and each with a stretched cloth section in front of him until the arranged between adjacent support profiles spacers gradually come out of engagement with the second guide and pushed together to form a support profile package. An unwanted sagging of the tissue sections is prevented in this way.

The support profiles take in the extended or clamped position of the folding awning the exploded position. Preferably, the spacer device holds adjacent support profiles in engagement with the second guide in this exploded position, with the advantage that the spacer device additionally stabilizes the folding awning in the extended position.

Preferably, the first guide and / or the second guide are formed by a guide rail, wherein the guide rail can be integrated, for example, in the longitudinal member.

In particular, it is provided that the second guide runs parallel to the first guide. In one possible embodiment, the first guide is formed by a guide rail extending over the entire length of the longitudinal member. The second guide also preferably runs along the longitudinal carrier below the first guide, but it is preferably provided that the second guide only over a partial region of the length of the first guide and in particular over approximately 60% to approximately 80%. the length of the 1st guide extends.

In a preferred embodiment of the invention, it is provided that the spacer device carries an engagement element which can be brought into engagement with the second guide. The engagement element may be a roller or a pair of rollers.

To ensure that the engagement element reliably engages or disengages the second guide, one can Ramp be provided for example in the form of a guide slope or a guide funnel, with which the engagement element is inserted into the second guide and discharged from this.

In one possible embodiment of the invention it is provided that the spacer device is a linkage with a plurality of linkage members, wherein the linkage members are hinged together. It can be provided that the linkage has exactly two linkage members which are connected to each other via a hinge. At their end remote from the joint, the linkage members are each connected via a further joint, in particular directly or indirectly, to the associated carrier profile.

The engagement element can be arranged in the region of the joint. If the support profile is a single roller, its axis of rotation may coincide with the hinge axis.

In an alternative embodiment of the invention it is provided that the spacer device is a chain of a plurality of successively arranged, hingedly interconnected chain links. By means of a chain usually only tensile forces, but no compressive forces can be transmitted without additional measures. According to the invention can therefore be provided that the second guide is structurally designed so that the chain is guided in a pressure-resistant manner in the second guide, ie when applying a compressive force can not escape, so that the pressure force can be transmitted by means of the chain. A corresponding embodiment is given, for example, if the second guide as a U-shaped guide channel or even as Guide channel is designed with a closed profile.

The FIGS. 1 to 8 show a first embodiment of a folding awning 10 according to the invention. The folding awning 10 has a plurality of spaced longitudinal members 13, of which only one is shown. On the mutually facing sides of the longitudinal members 13 each extending in the longitudinal direction of the longitudinal member 13 first guide 15 is formed in the form of a guide rail.

There are a plurality of rod-like, parallel to each other arranged support profiles 11, 11 a, which extend perpendicular to the longitudinal member 13 and with its end in each case in engage the first guide 15 so that the support profiles 11, 11a along the first guide 15 and thus are perpendicular to its longitudinal extent displaced. At a right axial end of the longitudinal member 13 according to Figure 1 a drive device 22 is shown only schematically, the drive movement, for example by means of a rope or a belt on that support profile 11 is transferable, in the arrangement of the support sections 11, 11a of the drive device 22 on farthest away. This is according to FIG. 1 the left support section 11th

Between adjacent support profiles 11, 11 a each extending a cloth section 12 of an awning fabric. At the according to FIG. 1 Right end of the longitudinal member 13 is a stationary rod-shaped bracket 21 is provided, which is parallel to the support profiles 11, 11 a and the last cloth section 12 supports the end.

FIG. 1 shows the folding awning in the extended position in which the support profiles 11, 11a are arranged at a distance and span the respective tissue sections 12 between them.

Below the first guide 15, a second guide 19 is provided on the longitudinal member 13, which is likewise formed by a guide rail and runs parallel to the first guide 15. As FIG. 2 shows, the second guide 19 extends from the drive device 22 and the fixed bracket 21 facing away from the end of the longitudinal member 13 is not over the entire length of the longitudinal member 13, but goes at a distance to the stationary bracket 21 and the drive device 22 in a downwards directed rail-shaped ramp 25 via.

Below the second guide 19 is on the longitudinal beam 13 in the longitudinal direction of the longitudinal member 13 extending gutter 23 is formed, which has a U-shaped, open-topped cross-section. The tissue sections 12 are arranged at a distance above the gutter 23.

Between adjacent support profiles 11, 11a is in each case a spacer device 14 in the region of the axial ends of the support profiles 11, 11a, i. arranged near the longitudinal member 13. In the illustrated first embodiment, the spacer device 14 comprises a multi-linkage linkage 24 with a first link member 16 and a second link member 17. The link members 16 and 17 are connected at their ends facing each other via a hinge 18. The opposite, the respective support section 11, 11a facing the end of the link members 16 and 17 are each connected via a joint 27 with the respective support section 11, 11a.

As FIG. 2 shows, the linkage members 16 and 17 are in a relative to each other angled orientation, so that due to the construction of a mutually towards or away from each other directed relative movement between the support profiles 11 and 11a would be possible. In the area of the linkage members 16 and 17 connecting joint 18 is an engagement element 20 in the form of a roll (see FIG. 8 ), which engages longitudinally displaceable in the second guide 19. By engaging the engagement element 20 in the second guide 19, a relative displacement between the two link members 16 and 17 is prevented, so that the associated support profiles 11, 11 a at a predetermined distance are held as long as the engagement member 20 is engaged with the second guide 19.

If the folding awning 10 from the in the Figures 1 and 2 shown extended position is to be retracted, the drive device 22 is activated, whereby on the arranged at the opposite end of the longitudinal member 13 support section 11 according to the Figures 1 and 2 directed to the right in the direction of the stationary holder 21 feed movement along the first guide 19 is applied. Due to the spacing devices 14 arranged between adjacent support profiles 11, 11a, the engagement elements 20 of which engage with the second guide 19, the left outer support profile 11 can not perform a relative movement to the adjacent support profile 11a, but transfers the thrust forces directly to this adjacent support profile 11a, which passes on the shear forces to the next adjacent support section 11a for the same reason. This results in that first all supporting profiles 11, 11a as a unit in accordance with Figures 1 and 2 be moved to the right in the direction of the stationary bracket 21 until that according to the Figures 1 and 2 Right support section 11a is disposed near the stationary bracket 21. In this position, the engagement member 20 is the according to the Figures 1 and 2 Due to the inclined ramp 25, the engagement element 20 and thus the joint 18 of this spacer device 14 can escape downwards and the mutual distance between the two corresponding support profiles 11a can be reduced , as shown in Figures 3 and 4. In a further movement of the driven, according to the figures left support profile 11, the two according to the figures right support profiles moved towards each other until they are next to each other. The associated spacer device 14 with the link members 16 and 17 is arranged V-shaped below the support profiles 11a.

The movement of the driven according to the figures left support section 11 is continued until all support sections 11, 11 a are pushed together to form a support profile packing, as in the FIGS. 7 and 8 is shown.

In this way, it is ensured over approximately the entire length of the longitudinal member 13 when pulling the folding awning 10, that the arranged between adjacent support sections 11, 11a tissue sections are curious and in particular does not come into abutment or sliding contact with the underlying gutter 23.

The extension or clamping of the folding awning 10 from the in the FIGS. 7 and 8 shown retracted state correspondingly in the reverse direction, which is ensured by the arranged between adjacent support sections 11, 11a spacing devices 14 in this case that the tissue sections 12 are not dragged over the gutter 23.

The FIGS. 9 to 16 show a second embodiment of the inventive folding awning 10. The components that the components of the 1st embodiment according to the FIGS. 1 to 8 correspond, are provided with the same reference numerals. The folding awning 10 according to the second embodiment differs from the aforementioned first embodiment by the configuration of the spacing devices 14. Instead of a multi-linkage linkage, each spacer device 14 now formed by a chain 26 having a plurality of successively arranged, hingedly interconnected chain links. The chain links of the chain are hinged together so that the pivot axes of adjacent chain links parallel to the longitudinal direction of the support sections 11, 11a and perpendicular to the side rail 13 and thus perpendicular to the plane of the FIG. 10 run.

The second guide 19 is likewise formed by a guide rail extending in the longitudinal direction of the longitudinal member 13, preferably with a C-shaped cross-section which ends at a distance from the stationary holder 21. A ramp is not provided here.

The chain 26 is fitted tightly into the guide rail of the second guide 19, so that it is prevented from escaping and thereby guided in a pressure-resistant manner, which means that pressure forces can also be transmitted reliably by means of the chain. Since the chain 26 is both pressure-resistant and tension-resistant in its state received in the second guide 19, the mutual spacing between adjacent support profiles 11, 11a is invariable, as long as the chain extending between these two support profiles 11, 11a is received in the second guide 19 is.

If for pulling the folding awning 10 from the in the FIGS. 9 and 10 shown position, the drive movement is transmitted in the manner mentioned on the left according to the figures support profile 11, all supporting profiles 11, 11a move first as a unit according to the figures to the right in the direction of the fixed bracket 21 to the stationary bracket 21 adjacent, according to the Figures right support profile 11a is shifted beyond the end of the second guide 19. The arranged between this support section 11 a and the subsequent support section 11 a chain 26 is then gradually released from the second guide 19 and is characterized by sagging and hanging down through, as in the FIGS. 11 and 12 is shown.

The further movement of the left according to the figures supporting profile 11 causes successively all supporting profiles along the first guide 15 are moved beyond the end of the second guide 19 and arrange to form a support profile stack near the stationary bracket 21, wherein the Chains 26 each hang down, as shown in Figures 15 and 16.

The extension or clamping of the folding awning 10 is carried out accordingly in the opposite direction, the chains 26 after entering the guide rail of the second guide 19 again assume their pressure-rigid configuration.
