Description

DESCRIPTION

Awning

The invention relates to an awning with an awning canvas and an awning roller on which the awning canvas can be rolled up, with awning arms and with awning legs that can be stored inside the awning roller. These awnings are already known. DE 202014 104014 U1, for example, shows such an awning. DE 20 2010 008210 U1 also describes such an awning. In this awning, the awning arms are coupled to the awning roller by means of a double hinge, in particular by means of a swivel joint rotatably arranged on the awning roller.

The invention has set itself the objective of creating such an awning and improving its stability. This task is solved with the awning described in claim 1.

The awning according to the invention has an awning canvas. The awning furthermore has an awning roller provided with a longitudinal extension on which the awning canvas can be rolled up. Awning arms and legs are respectively provided with a longitudinal extension. The awning arms and legs can be stored inside the awning roller. The awning arms have a flattened cross section, with one measurement longer and another shorter. The longest measurement is preferably perpendicular to the shortest. The longest measurement is preferably perpendicular to the shortest measurement. The longest measurement is preferably the longest cross-sectional measurement. Fixing elements are provided for fixing the awning arms to the awning roller. The fixing elements comprise a rotary joint by means of which the awning arms can rotate with respect to the awning roller, preferably around an axis of rotation that runs perpendicular to the longitudinal extension of the awning arms. The fixing elements further comprise a rotary arm joint by means of which the awning arms can rotate about a rotational axis parallel to their longitudinal extension. This creates a precondition for the awning arms to be arranged on the awning roller next to the awning legs so that they can make the most of the available space on the awning roller, which can be removed from the awning roller and re-insert it comfortably and that, in the assembled state, can be arranged in their ideal turning position against vertical bending. The smallest possible vertical deflection can have a positive effect on the pressure bearing capacity of the awning arms in the direction of their longitudinal extension. In this way, a greater tension can be achieved on the awning canvas.

The axis of rotation of the rotary joint is preferably always perpendicular to the longitudinal extension of the awning arms and especially preferably always perpendicular to the longitudinal extension of the awning roller.

To make the most of the space available on the awning roller, the awning arms can, for example, be molded and arranged next to an awning leg on the awning roller in such a way that their cross section, together with the cross section of the leg, roughly corresponds to the cross section of the hollow space of the awning roller.

The flattened cross section preferably causes a surface moment of inertia, preferably an axial surface moment of inertia, which depends on the rotational position of the awning arms, preferably so that the highest axial surface moment of inertia is exactly achieved in a rotary position and a lower axial surface moment of inertia is achieved in a rotational position of the awning arms rotated 90 ° to this. In other words, when the awning arms are oriented with their longitudinal extension horizontally, they have, depending on their position of rotation around their longitudinal extension, a different height, so their resistance to vertical bending depends on this. turning position.

The awning roller is preferably hollow, especially in the shape of a tube. The awning roller preferably has an at least approximately cylindrical hollow shape, especially with a circular base. The awning roller can contain aluminum. The same applies to the arms and / or legs of the awning.

When storing the awning arms, they are preferably arranged with their longitudinal extension parallel to the longitudinal extension of the awning roller. In the assembled state of the awning, the longitudinal extent of the awning arms is preferably at least approximately perpendicular to the longitudinal extent of the awning roller. The rotary joint preferably comprises two rotary joint parts rotatably connected to each other. One of these parts of the swivel joint preferably comprises a fork, which constitutes the part of the swivel joint facing the respective awning arm. The other part of the swivel joint preferably comprises a projection, which can also be described as a flap and which preferably also has a perforation. The projection is preferably arranged on the yoke and further constitutes the part of the swivel joint facing the awning roller. The rotary joint also comprises a rotary joint bolt which defines with particular preference the axis of rotation and which preferably connects the yoke and the projection.

The awning arms and / or legs are preferably arranged on the awning roller so that they cannot be lost, even after they have been removed from the roller for the purpose of mounting the awning. The arms and / or awning legs are preferably inseparably arranged on the awning roller. The awning arms and / or legs are preferably telescopic.

The awning can preferably be stored in a state where it can be positioned so that it takes up little space. In the storage state, the arms and legs can preferably be stored on the awning roller. To make the most of the space in the awning roller, the awning arm can be stowed in the awning roller so that an imaginary extension of the shortest measurement of its cross-sectional area passes through the awning leg. The cross-sectional area of the awning arm may be roughly in the shape of a semicircle. It is preferably approximately semicircular, with a flattening against the line that separates the semicircular shape from the imaginary full-circle shape.

The awning leg also preferably has a flat cross section, with a longer measurement and a shorter measurement perpendicular to the former. The cross-sectional area of the canopy legs can be similar or identical to the cross-sectional area of the canopy arms.

Fixing elements can be provided for fixing the awning legs to the awning roller, which can be designed in the same way as the fastening means for the awning arms. When the awning is stored, the fixing elements of the awning arms and / or legs are preferably arranged on the awning roller.

The canopy arms and legs are preferably stored in the canopy roller so that the axes of their pivoting joints extend parallel to each other. In this way it is possible to rotate them, after extraction, in the same direction, for example downwards, without interfering with each other.

The term "parallel to each other" defines in this printed memory both a congruence and a parallel development of the pieces.

The awning arms and / or legs are preferably stored in the awning roller such that the shortest measurements of their cross-sections run parallel to the axis of rotation of their swivel joints.

The swivel joint of the arm allows the awning arms to rotate about the axis of rotation parallel to their longitudinal extension regardless of any rotation of the swivel. Therefore, the rotary joint of the arm preferably allows a rotation of the awning arms about the axis of rotation parallel to their longitudinal extension even after a rotation of the awning arm relative to the awning roller, approximately such that the longitudinal extension of the canopy arms is at least approximately perpendicular to the longitudinal extension of the canopy roller.

The swivel joint of the arm allows the arm to rotate relative to its swivel joint. Preferably, the rotary joint of the arm comprises a rotationally symmetrical projection, particularly preferably rotatably arranged in a complementary recess. The rotary joint of the arm preferably comprises two rotary joint parts rotatably connected to each other. One of these parts of the swivel joint preferably comprises a rotationally symmetrical projection which especially preferably forms the swivel joint part facing the awning roller. The other part of the swivel joint preferably comprises a recess, preferably a complementary recess. The projection is preferably rotatably arranged in the recess. The projection preferably defines the axis of rotation of the pivot joint of the arm. The recess preferably forms the part of the swivel joint facing the respective awning arm. The swivel joint of the arm preferably comprises a safety element, which particularly preferably ensures the retention of the projection in the recess. The security element can also be defined as a connecting element between the projection and the recess. The security element preferably comprises a screw.

The rotary joint of the arm preferably has a rotation limitation. The limitation of rotation preferably limits the ability of rotation of the two parts of the rotary joint rotatably connected to each other. The twist limiter limits the turning ability of the two parts of the rotary joint rotatably connected to each other preferably to an angular range which can be between 70 ° and 110 °. The limitation of the rotational capacity of the two rotationally connected parts of the rotary joint preferably corresponds to 90 °. The rotation limitation preferably comprises a stop surface arranged on one of the two parts of the rotary joint rotatably connected to each other and a contracting surface arranged on the other part of the rotary joint. Preferably, the limitation of rotation causes a limitation in both directions of rotation. Therefore, two abutment surfaces and two contracting surfaces spaced apart from each other are preferably provided.

The swivel joint of the arm preferably has a swivel stop. This preferably prevents an inadvertent rotation. The rotation lock stop preferably comprises elements to increase and maintain the rotation friction that preferably occurs during a rotation in the rotary joint of the arm. Advantageously, the rotation locking stop does not prevent the rotation in the rotary joint of the arm, but preferably only increases the friction to be overcome.

Preferably, the elements for increasing and preferably maintaining the rotational friction comprise an elastic element. The elastic element preferably ensures the maintenance of a selectable contact pressure between the two rotatably connected parts of the rotary joint of the arm, even after numerous actuations of the swivel joint of the arm. The elements for increasing and preferably maintaining the rotational friction preferably comprise an elastic element which preferably acts on the safety element. A washer can be provided between the elastic element and the safety element.

The fixing elements preferably have a rotary joint that allows the awning arms to rotate around an axis of rotation parallel to the longitudinal extension of the awning roller and which within the framework of this printed memory preferably receives the name of the rotary joint of the roller.

Preferably, the two rotationally connected parts of the rotary joint are respectively rotatable by means of a rotary joint relative to the adjacent parts. The two rotatably connected parts of the swivel joint are preferably parts of a pivot joint adjacent to the swivel joint.

Preferably, the part of the swivel joint facing the awning roller is also part of the swivel joint of the roller. Preferably the part of the swivel joint facing the awning arm forms part of the swivel joint of the arm.

The fixing elements preferably allow a rotation of the awning arms about three independent axes, especially in relation to the awning roller.

The attachment of the awning arms to the awning roller preferably allows a rotation of the awning arms relative to the awning roller in the three degrees of freedom of rotation.

The fixing elements preferably comprise an element arranged in the manner of a plunger which, inside the awning roller, performs a reciprocating movement. The rotary joint, the rotary joint of the arm and preferably also the rotary joint of the roller, preferably fix the awning arms to this element. The element, which is designed as a plunger that performs a reciprocating movement inside the awning roller, is preferably arranged on this roller so that it can rotate relative to the awning roller.

The tarpaulin roller is preferably arranged at the edge of the tarpaulin which, in the unrolling direction of the tarpaulin, is the former.

In principle, it is conceivable that the awning is provided with articulated arms which, for example, have a pivotal articulation at half their length. However, the awning arms are preferably not designed as hinged arms. The arms and legs of the awning are preferably telescopic.

The awning is preferably opened manually. Within the scope of this printed specification this means that the awning is not opened with a crank or a motor, but by unrolling the awning fabric manually from the roller. To do this, the awning roller is rotated while being held in the hand.

Exactly one end piece can be arranged at each end of the awning roller. This end piece can close or reduce the gap between the awning arms and legs and the awning roller, thus making it difficult for impurities to enter the awning roller as well as creating a sliding support for the awning arms and legs during the introduction of the same in the roller or during its extraction from the awning roller. Preferably, each end piece has an opening through which the arms and legs can slide, especially during assembly or disassembly of the awning. The opening is preferably oval, especially preferably elliptical. In one embodiment the canopy is a bag canopy. Therefore, it does not have a housing, but is stored in a bag, which can preferably be mounted in a caravan. In principle, it is also possible that the awning is a cassette awning and therefore has a housing, for example made of aluminum, in which it can be stored. In the following, the invention will now be explained in more detail in view of an exemplary embodiment represented in the drawings. These show in the:

Figure 6 shows a representation like that of figure 5, but with the awning arm rotated around the articulation of the arm;

Figure 8 shows a representation like that of figure 7, from a different angle.

The exemplary embodiment of the awning according to the invention, which in the drawings is identified together with the number 100, is a bag awning. As shown in FIG. 1, the awning can be stored in an awning bag 20. For closing and opening the awning bag 20 a zipper is provided. In the illustrated embodiments, the awning has been arranged in a caravan 19.

As seen, for example, in figure 1, the awning 100 has two arms 3, 3 'and two legs 4, 4'. The arms 3, 3 'and the legs 4, 4' are telescopic. The awning is provided with an awning canvas 1. In the developed direction R there is arranged, at the leading edge of the awning canvas 1, an awning roller 3 (see FIG. 1).

As Figures 2 and 3 show, exactly one arm 3 and one leg 4 can be stored in one half of the hollow awning roller 2. Accordingly, the two arms and the two awning legs can be stored in the awning roller. For these reasons, the awning can be folded in very little space.

The awning arms 3, 3 'and the awning legs 4, 4' are fixed by means of fixing elements 5 on the awning roller 2.

At each end of the awning roller 2 an end piece 21 is arranged, thereby creating a sliding support for the awning arms 3, 3 'and the awning legs 4, 4' during their introduction into the awning roller. 2 or extraction thereof. Each end piece 21 has an opening through which the arms and legs can be inserted or extracted, especially during assembly or disassembly of the awning. The opening is elliptical.

Figure 4a shows, for example, that the awning arms 3, 3 'are provided with a flattened cross section with a longer measurement L and a shorter measurement K perpendicular to the former. The cross-sectional surface A has in the illustrated embodiment an approximately semicircular shape, with a flattening 18 against line 17 that separates the approximately semicircular shape from the surface of an imaginary surface shape that describes approximately a complete circle. A comparison of Figures 2 and 3 with Figures 1 and 4 shows that in the storage state the awning arms 3, 3 'are arranged on the awning roller with their longitudinal extension LA parallel to the longitudinal extension LR of the roller. awning 2, while in the assembled state the longitudinal extension LA of the awning arms 3, 3 'develops at least approximately perpendicular to the longitudinal extension LR of the awning roller 2.

Figure 4b shows schematically the arrangement of an awning arm 3 next to an awning leg 4 on the awning roller 2. For simplicity, the cross section of the arm and the awning leg are represented in this illustration in a semicircular shape without flattening. For simplicity's sake, the final piece is not shown either. The fixing elements 5 comprise a rotary joint 6, by means of which the awning arms 3, 3 'can rotate around a rotation axis S perpendicular to their longitudinal extension LA in relation to the awning roller 2 (see, eg Figures 4 and 5). The fixing elements 5 also comprise a rotary joint 7, by means of which the awning arms 3, 3 'can rotate about a rotation axis AD in relation to the rotary joint 6, this rotation axis developing parallel to the longitudinal extension LA of the awning arms. The swivel joint of the arm 7 allows the awning arms 3, 3 'to rotate around the axis of rotation AD, which runs parallel to the longitudinal extension LA of the arms 3, 3', regardless of the rotation of the swivel joint 6.

Figure 6 shows an awning arm 3 'in a position rotated in the direction of arrow P about the axis of rotation AD extending parallel to its longitudinal extension LA. In the pivoting position shown in figure 5, the awning arm 3 'can be stored together with the awning leg 4' on the awning roller 2 to save space. In the rotational position shown in FIG. 6, its bending is reduced thanks to the greater measure L of its cross-sectional area A, which now develops at least approximately vertically.

The rotary joint of the arm 7 comprises a rotationally symmetrical projection 10 arranged in a complementary recess 11 (see Figures 7 and 8).

The rotary joint of the arm further comprises a safety element 14 that ensures retention of the projection 10 in the recess 11.

To carry out a rotation limitation 12 that limits the rotation capacity of the awning arm 3, 3 'in the embodiment shown at 90 °, it is provided in one of the two parts 7a that are rotatably connected to each other. a projection with two abutment surfaces 12a spaced from one another, with contracting surfaces 12a formed by a recess on the other part 7b of the rotary joint, of which only one can be seen in the drawings (figure 7) .

To carry out a rotation lock 13, elements 15 are provided that increase and maintain the rotation friction. These means 15 comprise an elastic element 16 that acts on the locking element 14 configured in the form of a screw. Between the elastic element 16 and the safety element 14 a washer 22 is placed. As a consequence of the elastic element 16 there is always a constant clamping pressure between the two rotatably connected parts of the rotary arm joint 7a, 7b, allowing to select friction and avoid that the awning arm 3 'unintentionally returns from the vertical position shown in figure 6 to the horizontal position shown in figure 5.

Figures 5 and 6, for example, further show that the fixing elements 5 are provided with a rotary roller joint 8, which allows the awning arms 3, 3 'to rotate about an axis of rotation RD parallel to the extension. longitudinal LR of the awning roller. It can also be seen that the two rotationally connected parts 6a, 6b of the rotary joint 6 respectively form a part of the two rotary joints adjacent to the rotary joint 6 (namely, the rotary arm joint 7 and the rotary joint roller 8).

The fixing elements 5 therefore allow a rotation of the awning arms 3, 3 'about three independent axes S, AD, RD in relation to the awning roller 2. The element 9 of the fixing elements 5 arranged as a plunger inside the awning roller so that it can perform a reciprocating movement, can be seen, for example, in Figures 5 and 6. This element can be designed in such a way that it cannot rotate in relation to the awning roller 2.
