Description

Awning

The invention relates to a canopy, comprising: the roller is provided with a canopy cloth and a canopy roller, a canopy arm and a canopy leg, the canopy cloth can be wound on the canopy roller, and the canopy arm and the canopy leg can be accommodated in the canopy roller. Such canopies are known. DE202014104014U1, for example, shows one such canopy. DE202010008210U1 also shows one such canopy. In the canopy, the canopy arms are connected to the canopy rollers by means of a double joint, more precisely by means of a pivot joint, which is rotatably arranged on the canopy rollers. The aim of the invention is to create a canopy in which the stability is improved. This object is achieved by the canopy according to the invention.

The invention relates to an awning, comprising: a covering cloth; a awning roller having a longitudinal extension, around which the awning cloth can be wound; a canopy arm having a longitudinal extension; and canopy legs, in which canopy arms and canopy legs can be accommodated inside a canopy roller, wherein the canopy arms have a flattened cross section with a longer dimension and a shorter dimension, wherein fixing means are provided for fixing the canopy arms on the canopy roller, and the fixing means comprise a pivot hinge, by means of which the canopy arms can be pivoted about a pivot axis relative to the canopy roller, wherein the fixing means comprise an arm rotation hinge, by means of which the canopy arms can be rotated about a rotation axis parallel to the longitudinal extension of the canopy arms and relative to the pivot hinge of the canopy arms.

The canopy according to the invention comprises a canopy cloth. Furthermore, the canopy comprises a canopy roller with a longitudinal extension, on which the canopy cloth can be wound. Canopy arms and canopy legs are provided, each having a longitudinal extension. The canopy arms and canopy legs can be stowed inside the canopy roller. The canopy arms have a flattened cross-section that includes a longer dimension and a shorter dimension. The longer dimension is preferably perpendicular to the shorter dimension. The longer dimension is preferably the longest dimension of the cross-section. Fixing means are provided for fixing the canopy arm to the canopy roller. The fixing means comprise a pivot hinge, by means of which the canopy arms can be pivoted relative to the canopy roller, preferably about a pivot axis extending perpendicularly to the longitudinal extension of the canopy arms. The fixing means further comprise an arm rotation hinge by means of which the canopy arm can be rotated about an axis of rotation parallel to the longitudinal extension of the canopy arm. Thereby creating a premise for the following structure: the canopy arms can be arranged in the canopy rollers next to the canopy legs in such a way that the canopy arms and the canopy legs can utilize the available space in the canopy rollers as well as possible, can be moved out of and into the canopy rollers comfortably, and can be arranged in a desired rotational position of the canopy arms and the canopy legs against vertical deflection in the set-up state. As little vertical deflection as possible has a positive effect on the pressure-loading capacity of the canopy arm in the direction of the longitudinal extension of the canopy arm. In this way a higher tension in the awning cloth can be achieved.

The pivot axis of the pivot hinge preferably extends at all times perpendicularly to the longitudinal extension of the canopy arm and further preferably at all times perpendicularly to the longitudinal extension of the canopy roller.

In order to make the best possible use of the available space in the canopy roller, the canopy arms can be shaped and arranged in the canopy roller next to the canopy legs in such a way that their cross section together with the cross section of the legs approximately corresponds to the cross section of the canopy roller cavity.

The flattened cross section preferably causes an area moment of inertia, preferably an axial area moment of inertia, as a function of the rotational position of the canopy arm, preferably such that in exactly one rotational position a maximum axial area moment of inertia is achieved, while in the rotational position of the canopy arm that is rotated by 90 ° relative thereto a smaller axial area moment of inertia is present. In other words, when the canopy arms are oriented horizontally with their longitudinal extension, they have different heights depending on the rotational position about their longitudinal extension, so that the resistance of the canopy arms against vertical deflection is dependent on this rotational position.

The canopy roller is preferably hollow, particularly preferably tubular. The canopy roller preferably has an at least approximately hollow-cylindrical shape, preferably a circular bottom surface. The canopy rollers may comprise aluminum. The same preferably applies to the canopy arms and/or the canopy legs.

Preferably, the canopy arm is arranged in the canopy roller with its longitudinal extension parallel to the longitudinal extension of the canopy roller in the stowed state of the canopy. Preferably, in the raised state of the canopy, the longitudinal extension of the canopy arm extends at least approximately perpendicularly to the longitudinal extension of the canopy roller.

The pivot hinge preferably comprises two pivotally interconnected pivot hinge parts. One of these pivot hinge parts preferably has a fork, which particularly preferably forms the pivot hinge part facing the respective canopy arm. The other pivoting hinge part preferably has a projection, which can also be referred to as a tab and which further preferably has a hole. The projection is preferably arranged in a fork and further preferably forms a pivoting hinge part towards the canopy roller. The pivot hinge further preferably comprises a pivot hinge pin which particularly preferably defines a pivot axis and preferably connects the fork with the projection.

The canopy arms and/or the canopy legs are preferably arranged in a loss-proof manner on the canopy roller, preferably even after the canopy arms and/or the canopy legs have been removed from the canopy roller for setting up the canopy. The canopy arms and/or the canopy legs are preferably arranged inseparably on the canopy roller. The canopy arms and/or the canopy legs are preferably designed to be telescopic.

The covering can preferably be brought into a storage state in which it can be stored in a space-saving manner. In the stowed state, the arms and legs are preferably disposed in the canopy roller. Preferably, a canopy arm is each received in the canopy roller next to a canopy leg. In order to make the best possible use of the space in the canopy roller, the canopy arms can be accommodated in the canopy roller in such a way that imaginary extensions of the shorter dimensions of the cross sections of the canopy arms extend through the canopy legs. The canopy arms may be approximately semi-circular in cross-section. Preferably, the canopy arm is approximately semi-circular in cross-section and has a flattened portion opposite a line separating the semi-circular shape from an imaginary full circular shape.

The canopy legs preferably also have a flat cross-section with a longer dimension and a shorter dimension perpendicular thereto. The canopy legs can be configured with a cross-section similar or identical to the cross-section of the canopy arms.

Fastening means for fastening the canopy legs to the canopy roller can be provided, which can be configured like the fastening means of the canopy arms. Preferably, in the stowed state of the canopy, the fixing means of the canopy arms and/or the canopy legs are arranged in the canopy roller.

The canopy arms and the canopy legs can preferably be accommodated in the canopy roller in such a way that the pivot axes of the pivot hinges of the canopy arms and the canopy legs extend parallel to one another. The canopy arms and the canopy legs can thus preferably be pivoted in the same direction, for example downwards, comfortably after removal from the canopy roller, without mutual interference.

Preferably, the term "extend parallel to each other" in the present context means not only coincidence but also parallel extension to each other at a distance apart.

The canopy arms and/or canopy legs can preferably be accommodated in the canopy roller in such a way that the shorter dimension of the cross section of the canopy arms and/or canopy legs is parallel to the pivot axis of their pivot hinge.

Preferably, the arm rotation hinge allows rotatability of the canopy arm about an axis of rotation parallel to the longitudinal extension of the canopy arm independent of the pivoting of the pivot hinge. The arm rotation hinge thus preferably also allows a rotation of the canopy arm about a rotation axis parallel to the longitudinal extension of the canopy arm when the canopy arm is pivoted relative to the canopy roller, for example such that the longitudinal extension of the canopy arm extends at least approximately perpendicularly to the longitudinal extension of the canopy roller.

The arm rotation hinge allows rotation of the arm relative to the pivot hinge of the arm. Preferably, the arm rotation hinge comprises a rotationally symmetrical protrusion, which is further preferably rotatably arranged in a recess complementary to the protrusion. The arm swivel hinge preferably comprises two swivel hinge parts which are rotatably connected to each other. One of the swivel hinge parts preferably comprises a rotationally symmetrical projection which further preferably forms the swivel hinge part towards the canopy roller. The further swivel hinge part preferably comprises a recess, preferably a recess complementary to the projection. The projection is preferably rotatably disposed in the recess. The projection preferably defines the axis of rotation of the arm rotation hinge. The recesses preferably form a swivel hinge part towards the respective canopy arm. The arm turning hinge preferably comprises a locking means which further preferably locks the retention of the protrusion in the recess. The locking means may also be referred to as connecting means between the protrusion and the recess. The locking means preferably comprises a screw.

The arm rotation hinge preferably includes a rotation restricting portion. The rotation limiting section preferably limits the rotatability of the two rotatably interconnected rotating hinge parts. The rotation limitation preferably limits the rotatability of the two rotatably interconnected rotating hinge parts to an angular range, which may be between 70 ° and 110 °. The rotation limiting section preferably limits the rotatability of the two rotatably interconnected rotating hinge parts to an angular range of about 90 °. The rotation-limiting portion preferably comprises a stop face provided on one of the two rotatably interconnected rotary hinge parts and a mating stop face provided on the other rotary hinge part. Preferably, the rotation restricting portion causes restriction in both rotational directions. Thus, two stop faces and two cooperating stop faces at a distance from each other are preferably provided.

The arm rotation hinge preferably has a rotation locking portion. This preferably prevents accidental rotation. Preferably, the rotation-blocking part comprises means for increasing and preferably maintaining the rotational friction, which preferably occurs upon rotation in the arm rotation hinge. Advantageously, the rotation-blocking part does not prevent rotation in the arm rotation hinge, but rather preferably only increases the friction to be overcome at this time.

Preferably, said means for increasing and preferably maintaining rotational friction comprises a spring element. The spring element preferably ensures that a selectable pressing pressure between the two rotatably interconnected rotary hinge parts of the arm rotary hinge is maintained even after a plurality of operations on the arm rotary hinge. The means for increasing and preferably maintaining the rotational friction preferably comprise a spring element, which preferably acts on the locking means. A washer may be provided between the spring element and the locking means.

Preferably, the fixing means comprise a rotation hinge allowing the canopy arm to rotate about an axis of rotation parallel to the longitudinal extension of the canopy roller and is preferably referred to in the present context as a roller rotation hinge.

Preferably, two pivotably interconnected parts of the pivot hinge can be rotated relative to adjacent parts by means of a rotary hinge. Preferably, the two pivotably interconnected parts of the pivot hinge are parts of a rotary hinge which adjoin the pivot hinge in each case.

Furthermore, it is preferred that the part of the pivoting hinge facing the awning roller is a part of the roller turning hinge. Preferably, the part of the pivot hinge facing the canopy arm is a part of the arm rotation hinge.

Preferably, the fixing means allow rotatability of the canopy arm about three mutually independent axes, preferably with respect to the canopy roller.

The fixing of the canopy arm on the canopy roller preferably allows the canopy arm to be rotated relative to the canopy roller about all three rotational degrees of freedom.

Preferably, the fixing means comprise an element arranged in the form of a piston that can be reciprocated inside the awning roller. The pivot hinge, the arm rotation hinge and preferably the roller rotation hinge preferably fix the canopy arm to the element. The element, which is designed in the form of a piston that can be moved back and forth within the roller, is preferably arranged in the roller in a rotationally fixed manner relative to the roller.

Preferably, the awning roller is provided on a front edge of the awning cloth in an unfolding direction of the awning cloth.

In principle, it is conceivable for the canopy to have an articulated arm which has a pivot hinge, for example, over approximately half the length. But preferably the arms of the canopy are not designed as such articulated arms. Preferably, the canopy arms and the canopy legs are telescopically configured.

The canopy is preferably manually openable. This means in the context of this document, in particular, that the awning is not opened by means of a crank or a motor, but rather by manually unrolling the awning cloth from the awning roller. This is preferably done by turning the sunshade roller while keeping it in hand.

Exactly one end piece can be provided on each end of the awning roller. The end pieces can close or reduce the gap between the canopy arms and the canopy legs and the canopy rollers and can thus increase the difficulty of dirt penetrating into the canopy rollers and can cause sliding support of the canopy arms and the canopy legs during the movement into and out of the canopy rollers. Preferably, each end piece has an opening through which the arms and legs can slide back and forth, especially during setting up or stowing of the awning. The opening is preferably egg-shaped, particularly preferably oval. In one embodiment, the canopy is a bag canopy. Thus, the canopy does not have a housing, but rather can be housed in a bag that is preferably mountable to the camper. In principle, it is also conceivable for the canopy to be a box canopy and thus to have a housing, for example made of aluminum, in which the canopy can be accommodated.

The invention will now be explained in more detail with the aid of embodiments shown in the drawings. Here:

fig. 8 shows a view as in fig. 7 from another perspective.

The embodiment of the canopy according to the invention shown in the figures and designated as a whole by 100 is a pocket canopy. As shown, for example, in fig. 1, the canopy can be received in a canopy pocket 20. The canopy pocket 20 has a zipper for opening and closing. In the illustrated embodiment, the canopy is provided on the caravan 19.

As shown for example in fig. 1, the canopy 100 has two arms 3, 3 'and two legs 4, 4'. The arms 3, 3 'and legs 4, 4' are telescopically arranged. The canopy has a canopy cloth 1. A canopy roller 2 is provided on the front edge of the canopy cloth 1 in the deployment direction R (see fig. 1).

As can be seen for example in fig. 2 and 3, exactly one arm 3 and exactly one leg 4 can be accommodated in each half of the hollow awning roller 2. Two canopy arms and two canopy legs can thus be accommodated in the canopy roller. For these reasons, the canopy can be folded very space-saving.

The canopy arms 3, 3 'and the canopy legs 4, 4' are non-detachably fixed to the canopy roller 2 by means of fixing means 5.

On each end of the roller 2, an end piece 21 is provided, which brings about a sliding bearing of the canopy arms 3, 3 'and the canopy legs 4, 4' during the movement into and out of the roller 2. Each end piece 21 has an opening through which the arms and legs can slide back and forth, especially during the erection and retraction of the awning. The opening is oval.

For example, as shown in fig. 4a, the awning arms 3, 3' have a flattened cross-section with a longer dimension L and a shorter dimension K perpendicular to the longer dimension. The cross section a is approximately semi-circular in the embodiment shown, with a flattened portion 18 relative to a straight line 17 separating the approximately semi-circular shape from the imaginary approximately full circular shape. As can be seen by comparing fig. 2 and 3 with fig. 1 and 4, the canopy arms 3, 3 'are arranged with their longitudinal extension LA parallel to the longitudinal extension LR of the canopy roller 2 in the stowed state, while the longitudinal extension LA of the canopy arms 3, 3' extends at least approximately perpendicularly to the longitudinal extension LR of the canopy roller 2 in the set-up state.

Fig. 4b schematically shows the canopy arm 3 arranged next to the canopy leg 4 in the canopy roller 2. In this view, the canopy arms and canopy legs are shown in cross-section in a semi-circle without skived portions for simplicity. The end pieces are also not considered for simplicity.

The fixing means 5 comprise a pivot hinge 6, by means of which the canopy arms 3, 3' can be pivoted relative to the canopy roller 2 about a pivot axis S extending perpendicularly to their longitudinal extension LA (see, for example, fig. 4 and 5). Furthermore, the fixing means 5 comprise a swivel hinge 7, by means of which the canopy arms 3, 3' can be swiveled relative to the pivot hinge 6 about a swivel axis AD, wherein the swivel axis extends parallel to the longitudinal extension LA of the canopy arms. The arm pivot joint 7 allows a rotatability of the canopy arms 3, 3 'independently of the pivoting of the pivot joint 6 about a pivot axis AD which runs parallel to the longitudinal extension LA of the canopy arms 3, 3'.

Fig. 6 shows the canopy arm 3' in a rotated position, which has been rotated in the direction of the arrow P by means of the arm rotation hinge 7 about a rotation axis AD extending parallel to the longitudinal extension LA of the canopy arm. In the pivoted position shown in fig. 5, the canopy arms 3 'can be accommodated in the canopy roller 2 together with the canopy legs 4' in a space-saving manner. In the pivoted position shown in fig. 6, the deflection of the canopy arm is reduced, since the greater dimension L of the cross section a of the canopy arm now extends at least approximately vertically.

The arm pivot hinge 7 comprises a rotationally symmetrical projection 10 which is arranged in a recess 11 complementary to the projection (see for example fig. 7 and 8).

The arm turning hinge 7 further comprises locking means 14 which lock the retention of the protrusion 10 in the recess 11.

In order to realize a rotation limiter 12, which in the illustrated embodiment limits the rotatability of the canopy arm 3, 3' to 90 °, one projection with two stop faces 12a at a distance from one another is provided on one 7a of the two rotatably interconnected rotary hinge parts, while a mating stop face 12b formed by a recess, only one of which is visible in the drawing (fig. 7), is provided on the other rotary hinge part 7 b.

To realize the rotation blocking portion, means 15 for increasing and maintaining the rotational friction is provided. These means 15 comprise a spring element 16 which acts on a locking means 14 configured as a screw. A washer 22 is provided between the spring element 16 and the locking device 14. Due to the spring element 16, there is always an equally maintained pressing pressure between the two rotatably interconnected arm-rotating hinge parts 7a, 7b, which causes a selectable friction that prevents an unintentional back-rotation of the canopy arm 3' from the vertical position shown in fig. 6 into the horizontal position shown in fig. 5.

As also shown for example in fig. 5 and 6, the fixing means 5 comprise a roller rotation hinge 8 which allows the awning arms 3, 3' to rotate about a rotation axis RD parallel to the longitudinal extension LR of the awning rollers. It can also be seen that the two pivotably interconnected parts 6a, 6b of the pivot joint 6 each form one part of two pivot joints (i.e. the arm pivot joint 7 and the roller pivot joint 8) adjacent to the pivot joint 6.

The fixing means 5 thus allow the rotatability of the awning arms 3, 3' relative to the awning roller 2 about three mutually independent axes S, AD, RD. For example, fig. 5 and 6 show an element 9 of the fastening device 5, which is provided in the form of a piston that can be moved back and forth inside the awning roller. Which element may be configured to be rotationally fixed relative to the awning roller 2.
