Description

The invention relates to an awning having an awning cloth and an awning roller, on which the awning cloth can be rolled up, having awning arms and awning legs, which can be stowed inside the awning roller. Such awnings are already known. For example, DE 20 2014 104 014 U1 depicts such an awning. The object of the invention is to create such an awning whose stability is improved. This object is achieved by the awning described in claim 1.

The awning according to the invention has an awning cloth. The awning also has an awning roller having a longitudinal extension on which the awning cloth can be rolled up. Awning arms and awning legs having a respective longitudinal extension are provided. The awning arms and the awning legs can be stowed inside the awning roller. The awning arms have a flattened cross-section, with a longer dimension and a shorter dimension. The longer dimension is preferably the longest dimension of the cross-section. Fastening means are provided for fastening the awning arms to the awning roller. The fastening means comprise a pivot joint, by means of which the awning arms can be pivoted relative to the awning roller, preferably about a pivot axis running perpendicular to the longitudinal extension of the awning arms. The fastening means also comprise an arm rotary joint, by means of which the awning arms can be rotated about an axis of rotation parallel to its longitudinal extension. This creates a prerequisite for the awning arms in the awning roller being arranged next to the awning legs in such a manner that they can make optimal use of the space available in the awning roller, can be moved conveniently out of and into the awning roller, and in a setup state can be arranged in their ideal rotational position against vertical deflection. A least possible vertical deflection \N0 2018/036744

PCT/EP2017/068906 may have a positive influence on the pressure load-bearing capability of the awning arms in the direction of their longitudinal extension. In this way, a higher tension in the awning cloth can be achieved.

The pivot axis of the pivot joint runs preferably always perpendicular to the longitudinal extension of the awning arms and in a more preferred manner always perpendicular to the longitudinal extension of the awning roller.

To best use the space available in the awning roller, the awning arms may be shaped and arranged next to the awning legs in the awning roller in such a manner that their cross-section along with the cross-section of the leg corresponds approximately to the cross-section of the hollow space of the awning roller.

The flattened cross-section preferably causes an area moment - preferably an axial area moment - which depends on the rotational position of the awning arms, preferably in such a manner that exactly at one rotational position, the largest axial area moment is achieved and given a rotational position of the awning arms turned by 90° to this, a smaller axial area moment is achieved. In other words, the awning arms, when their longitudinal extensions are oriented horizontally, have varying heights depending on the rotational position about their longitudinal extension so that their resistance to vertical deflection depends on this rotational position.

\N0 2018/036744

PCT/EP2017/068906

The awning roller is preferably hollow, and in a particularly preferred manner cylindrical. The awning roller has preferentially at least an approximately hollow cylindrical shape, preferably with a circular surface area. The awning roller may comprise aluminum. The same applies preferably for the awning arms and/or awning legs.

Preferably, when the awning is stowed, the awning arms along with their longitudinal extension are arranged parallel to the longitudinal extension of the awning roller inside of it. Preferably, when the awning is set up, the longitudinal extension of the awning arms runs at least approximately perpendicular to the longitudinal extension of the awning roller.

The pivot joint comprises preferably two pivot joint parts connected to each other in a pivotable manner. One of these pivot joint parts comprises preferably a fork, which forms in a particularly preferred manner the pivot joint part facing the respective awning arm. The other pivot joint part comprises preferably a protrusion, which can also preferably be referred to as a tab and which also preferably has a drill hole. The protrusion is preferably arranged in the fork and also forms more preferably the pivot joint part facing the awning roller. The pivot joint also comprises preferably a pivot joint bolt, which in a particularly preferred manner defines the pivot axis and preferably connects the fork to the protrusion.

The awning arms and/or awning legs are preferably arranged in a secure manner to the awning roller, preferentially even after they are rolled out of the awning roller for the purpose of setting up the awning. The awning arms and/or awning legs are preferably inseparably \N0 2018/036744

PCT/EP2017/068906 arranged on the awning roller. The awning arms and/or awning legs are preferably designed in a telescopic manner.

The awning is preferably portable in a stowed state by being stowable in a space-saving manner. In the stowed stated, the arms and legs are preferably arranged in the awning roller. Advantageously, an awning arm can be stowed next to an awning leg in the awning roller. To make use of the space in the awning roller, the awning arm can thereby be stowed in the awning roller in such a manner that a notional extension of the shorter dimension of its crosssectional surface runs through the awning leg. The cross-sectional surface of the awning arm may be approximately semi-circular. Preferably, it is approximately semi-circular, with a flattening positioned opposite the straight line, which separates the semicircular shape from the notional full-circle shape.

The awning leg also has preferably a flat cross-section, having a longer dimension and a shorter dimension perpendicular to it. The cross-sectional surface of the awning legs may be designed similar or identical to the cross-sectional surface of the awning arms.

Fastening means for fastening the awning legs to the awning roller may be provided, which may be designed like the fastening means of the awning arms. In the stowed state of the awning, the fastening means of the awning arms and/or the awning legs are preferably arranged in the awning roller.

The awning arms and the awning legs can be stowed in the awning roller preferably in such a manner that the pivot axes of their pivot joints run parallel to each other. They can hereby be pivoted - downward for example - in a preferably convenient manner without mutual interference after being taken out of the awning roller.

PCT/EP2017/068906

Within the scope of this document, the expression run parallel to each other refers to a congruency as well as running parallel to each other in a spaced-apart manner.

The awning arms and/or awning legs are preferably stowable in the awning roller such that the shorter dimensions of their cross-sections run parallel to the pivot axis of their pivot joints.

Preferably, the arm rotary joint allows rotatability of the awning arms about the axis of rotation parallel to its longitudinal extension independently of a pivoting of the pivot joint. The arm rotary joint thus preferably permits a rotation of the awning arms about the axis of rotation parallel to its longitudinal extension even when a pivoting of the awning arm has occurred relative to the awning roller - for example in such a manner that the longitudinal extension of the awning arms runs at least approximately perpendicular to the longitudinal extension of the awning roller.

Preferably, the arm rotary joint allows a rotation of the arm relative to its pivot joint.

Preferably, the arm rotary joint comprises a rotation-symmetrical protrusion, which is also preferably arranged in a rotatable manner in a recess complementary to said protrusion. The arm rotary joint preferentially comprises two rotatable interconnected rotary joint parts. One of these rotary joint parts preferably comprises a rotation-symmetric protrusion, which more preferably forms the rotary joint facing the awning roller. The other pivot joint part preferentially comprises a recess - preferentially complementary to it. The protrusion is preferably arranged rotatably in the recess. The protrusion preferably defines the axis of rotation of the arm rotary joint. The recess preferably forms the rotary joint part facing the respective awning arm. The arm rotary joint preferably comprises a securing means, which more preferably secures the retention of the protrusion in the recess. The securing means may also be referred to as a connecting means between the protrusion and the recess. The securing means preferentially comprises a screw.

\N0 2018/036744

PCT/EP2017/068906

The arm rotary joint preferably has a rotational limit. The rotational limit preferably limits the rotatability of the two rotatably interconnected pivot joint parts. The rotational limit preferably limits the rotatability of the two rotatably interconnected rotary joint parts to an angle range that can be between 70° and 110°. The rotational limit preferably limits the rotatability of the two rotatably interconnected rotary joint parts to an angle range of approximately 90°. The rotational limit preferentially comprises a contact surface arranged on one of the two rotatably interconnected rotary joint parts and a counter-contact surface arranged on the other rotary joint part. Preferably the rotational limit effectuates a limit in both rotational directions. In other words, preferably two contact surfaces and two spaced-apart counter-contact surfaces are provided.

The arm rotary joint preferably has a swivel lock. It preferably prevents an undesired rotation. Preferably, the swivel lock comprises means to increase and preferentially maintain rotational friction occurring preferentially when there is rotation in the arm rotary joint. Advantageously, the swivel lock does not prevent a rotation in the arm rotary joint, but preferentially only increases the friction to be hereby surmounted.

Preferably the means to increase and preferentially maintain rotational friction comprise a spring element. The spring element preferably ensures that a selectable contact pressure is retained between the two rotatably interconnected rotary joint parts of the arm rotary joint even after repeated actuation of the arm rotary joint. The means to increase and preferably maintain rotational friction preferentially comprise a spring element, which acts preferably on the securing means. A washer may be provided between the spring element and the securing means.

Preferentially the fastening means have a rotary joint, which allows a rotation of the awning arms about an axis of rotation parallel to the longitudinal extension of the awning roller and is preferably referred to as roller rotary joint within the scope of this document.

\N0 2018/036744

PCT/EP2017/068906

Preferentially both pivotably interconnected parts of the pivot joint can each be rotated by means of a rotary joint relative to adjoining parts. Preferentially both pivotably interconnected parts of the pivot joint are parts of a rotary joint adjoining the pivot joint in each case.

Preferably the part of the pivot joint facing the awning roller is also part of the roller rotary joint. Preferentially, the part of the pivot joint facing the awning roller is also part of the arm rotary joint.

Preferably the fastening means allow a rotatability of the awning arms about three mutually independent axes, preferably relative to the awning roller.

The fastening of the awning arms to the awning roller preferably allows a rotation of the awning arms relative to the awning roller about all three rotational degrees of freedom.

Preferentially, the fastening means comprise an element, which is arranged in the manner of a piston that moves back and forth inside the awning roller. The pivot joint, the arm rotary joint and preferably also the roller rotary joint fasten the awning arms preferably to this element. The element designed in the manner of a piston that moves back and forth inside the awning roller is preferentially arranged inside the awning roller in a manner that is rotationally fixed relative to it.

Preferentially, the awning roller is arranged on the front edge of the awning cloth in the unrolling direction of the awning cloth.

Basically it is conceivable that the awning has articulated arms, which for example have approximately a pivot joint halfway along their length. However, preferably the arms of the awning are not designed as such articulated arms. Preferably the awning arms and the awning legs are designed in a telescoping manner.

\N0 2018/036744

PCT/EP2017/068906

The awning is to be opened preferably in a manual manner. Within the scope of this document, this means in particular that it is not opened by cranking or in a motor-operated manner, but by rolling out the awning cloth from the awning roller by hand. This happens preferably by turning the awning roller, while it is held in one's hand.

On each end of the awning roller, there may be arranged exactly one end piece. This end piece may close or decrease the gap between the awning arms and awning legs and awning roller, and thereby impede the penetration of debris into the awning roller, and serve as a slide bearing of the awning arms and legs while moving the awning in or out of the awning roller. Preferably each end piece has an opening through which the arms and legs can be pushed in and out particularly while setting up or taking down the awning. The opening is preferably oval, and particularly preferably elliptical. In one embodiment, the awning is a bag awning.

Therefore, it has no housing, but can be stowed in a bag, which can be affixed to a camping mobile. Basically, it is also conceivable that the awning is a box awning and thus has a housing, out of aluminum for example, in which it can be stowed.

The invention is now to be explained in greater detail by means of an embodiment depicted in the drawings. Depicted are:

The embodiment, shown in the drawings and labeled 100 as a whole, of the awning according to the invention is a bag awning. As shown in Fig. 1 for example, the awning can be stowed in an awning bag 20. For the purposes of opening and closing, awning bag 20 has a zipper. In the depicted embodiments, the awning is arranged on a camper van.

As shown in Fig. 1 for example, awning 100 has two arms 3, 3' and two legs 4, 4'. Arms 3, 3' and legs 4, 4' are designed in a telescopic manner. The awning has an awning cloth 1. In unrolling direction R on the front edge of awning cloth 1, there is arranged an awning roller 3 (see Fig. 1).

As one can see for example in Figs. 2 and 3, exactly one arm 3 and one leg 4 can each be stowed in one half of hollow awning roller 2. Thus, both awning arms and both awning legs can be stowed in the awning roller. For these reasons, the awning can be folded up in a very spacesaving manner.

\N0 2018/036744

PCT/EP2017/068906

Awning arms 3, 3' and awning legs 4, 4' are permanently fastened to awning roller 2 by fastening means 5.

On each end of awning roller 2, there is arranged an end piece 21, which serves as a glide bearing of awning arms 3, 3' and awning legs 4, 4' while moving the awning into or out of the awning roller 2. Each end piece 21 has an opening, through which the arms and legs can be pushed back and forth, particularly when setting up or taking down the awning. The opening is elliptical.

Fig. 4a for example shows that awning arms 3, 3' have a flattened cross-section with a longer dimension L and a shorter dimension K perpendicular to it. In the depicted embodiment, crosssectional surface A is approximately semicircular, with a flattening 18 located opposite the straight line 17 delimiting an approximately semicircular shape from a notional approximately fully circular shape. A comparison of Figs. 2 and 3 in relation to Figs. 1 and 4 reveals that awning arms 3, 3' in the stowed state are arranged with their longitudinal extension LA parallel to longitudinal extension LR of awning roller 2 inside of it, while in the set-up state, the longitudinal extension LA of awning arms 3, 3' runs at least approximately perpendicular to longitudinal extension LR of awning roller 2.

Fig. 4b schematically depicts the arrangement of an awning arm 3 beside an awning leg 4 in awning roller 2. For the sake of simplicity, the illustration shows the cross-section of the awning arm and awning leg to be semicircular without flattening. The end piece is also not taken into account for the sake of simplicity.

Fastening means 5 comprise a pivot joint 6, by means of which awning arms 3, 3' can be pivoted relative to awning roller 2 about a pivot axis S running perpendicular to its longitudinal extension LA (see for example Figs. 4 and 5). In addition, fastening means 5 comprise a rotary joint 7, by means of which awning arms 3, 3' can be rotated relative to pivot joint 6 about an axis of rotation AD, wherein this axis of rotation runs parallel to longitudinal extension LA of the \N0 2018/036744

PCT/EP2017/068906 awning arms. Arm rotation joint 7 thereby allows the rotatability of awning arms 3, 3' about axis of rotation AD, which runs parallel to longitudinal extension LA of arms 3, 3', independently of a pivoting of pivot joint 6.

Fig. 6 depicts an awning arm 3' in a rotated position twisted in the direction of arrow P about axis of rotation AD that runs parallel to its longitudinal extension LA. In the rotated position shown in Fig. 5, awning arm 3' along with awning leg 4' can be stowed in a space-saving manner in awning roller 2. In the rotated position shown in Fig. 6, its deflection is decreased due to the larger dimension L of its cross-sectional surface A now running at least approximately vertically.

Arm rotary joint 7 comprises a rotation-symmetric protrusion 10, which is arranged in a hereto complementary recess 11 (see Figs. 7 and 8 for example).

The arm rotary joint also comprises a securing means 14, which secures the retention of protrusion 10 in recess 11.

To execute a rotational limit 12, which limits the rotatability of awning arm 3, 3' by 90° in the depicted embodiment, a protrusion having two spaced-apart contact surfaces 12a is provided on one of the two rotatably interconnected rotary joint parts 7a, and on the other rotary joint part 7b, there are provided counter-contact surfaces 12a, formed by a recess, of which only one can be seen in the drawings (Fig. 7).

To execute a swivel lock 13, means 15 are provided to increase and maintain rotational friction. These means 15 comprise a spring element 16, which acts on securing means 14, which is designed as a screw. A washer 22 is provided between spring element 16 and securing means 14. By means of spring element 16, there is always a constant contact pressure between the two rotatably interconnected arm rotation joint parts 7a, 7b; said pressure causes a selectable friction, which prevents an undesired turning-back of awning arm 3' from the vertical position shown in Fig. 6 into the horizontal position shown in Fig. 5.

\N0 2018/036744

PCT/EP2017/068906

For example, Figs. 5 and 6 also show that fastening means 5 have a roller rotary joint 8, which allows a rotation of the awning arms 3, 3' about axis of rotation RD parallel to longitudinal extension LR of the awning roller. In addition, one can see that the two pivotable, interconnected parts 6a, 6b of pivot joint 6 each form a part of the two rotary joints adjoining pivot joint 6 (namely, arm rotary joint 7 and roller rotary joint 8).

Therefore, fastening means 5 permit a rotatability of awning arms 3, 3' about three mutually independent axes S, AD, RD relative to awning roller 2. Element 9 of fastening means 5, which is arranged in the manner of a piston moving back and forth inside the awning roller, can be seen in Figs. 5 and 6 for example. It may be designed to be non-rotational in relation to awning roller

2.
