Description

Description:

Awning Fox Stabilization

The invention relates to an awning fox stabilization, in particular for an awning attached to a caravan or mobile home, according to the preamble of claim 1.

Awning fox stabilizations are known from use, which comprise a rail with two rail files. The rail files are designed to be movable relative to one another, so that an edge section of the awning fox can be clamped in with the rail files. The ends of the rail can be clamped between an awning housing, in which a first end of the awning bush is stored, and a cross member, which is attached to an opposite soap of the awning bush, so that the rail is held and the awning bush is tensioned . The awning fox can be tensioned, for example, by the awning fox being rolled up slightly, as a result of which the distance between the awning housing and the

Reduce crossbeam † and thus brace the rail located between them †.

The object of the invention is to provide an awning fox stabilization which is particularly quick to assemble and can be used individually

Awning screens of different sizes allow †.

This object is achieved in that a second rail with two rail files that can be moved relative to one another is mounted in a felescopic manner in the first rail for clamping in another edge section of the awning fox. Due to the mutually longitudinally displaceable mounting of the rails relative to one another like in a telescope, the length of the awning fox stabilization can be adapted particularly easily to the awning fox. Through the two movable to each other Rail parts of the first rail and the second rail can also first be attached to the inner rail on an edge section of the awning and then the outer rail to an adjacent edge section, which simplifies assembly †.

The rail parts of the first rail are preferably connected rotatably to one another via a swivel joint and / or the rail parts of the second rail are mutually rotatably connected to one another via a further swivel joint. The axes of rotation of the swivel joint can particularly preferably be arranged in parallel and offset from one another. As a result, the rails files of the first rail and the second rail can be opened and collapsed particularly easily. Instead of the connection via the swivel joint, however, a linear guide can also be provided, for example, along which the two rail parts of the first rail and / or the second rail can be moved in translation with respect to one another.

The at least one hinge of the first rail and / or the second

Rail can advantageously be formed in that a rail part of a rail encloses the other rail part of this rail in a form-fitting manner † and in particular the contact surface between the rail parts is partially circular in cross section. For example, a rail part at one end facing the further rail part can have a cross section that is circular, in particular at least in sections, which is held by the adjacent end of the further rail part. In order to prevent mutual separation of the rail parts, it can be provided that the further rail part encompasses the first rail part on the part-circular cross-section over an angular range of more than 180 °, so that the rail parts are positively held against one another. As an alternative or in addition, it can also be provided that the part-circular cross section on the first rail part is formed at least in sections by a nu † extending in cross section along an arc, the adjacent end of the second rail part protruding into the nu † and from it in the radial direction is positively held on both sides.

In order to be able to mutually adjust the first rail and the second rail in the form of a telescope, a rail part of the first rail can be attached to one

Rail part of the second rail can be moved longitudinally via a linear guide be connected. The linear guide is preferably † oriented in the longitudinal direction of the rails †, so that the rails can be pushed together completely.

In a particularly preferred embodiment, the linear guide can be formed by at least one projection on the rail part of the first rail which engages behind a guide on the rail part of the second rail †. This creates a stable, backlash-free and low-friction linear guide, which enables easy adjustment of the length of the awning fabric stabilization.

In order to releasably lock the linear guide, a holding element can be provided, for example a locking screw, which is mounted in the first rail and can be pressed onto the second rail by screws.

In order to press the rail parts of the first rail and / or the rail parts of the second rail mutually into a closed position, at least one spring can be provided, which is supported on the rail parts †. For exact positioning of the springs, the rail parts of the first rail and the second rail can particularly advantageously each have a recess in which the springs are mounted. The springs can be, for example, prestressed leaf springs which are arranged with their ends in the cutouts. Preferably, several springs are provided on the rails in the longitudinal direction offset from one another.

In order to enable easy opening of the rails, an outwardly projecting grip section can be provided on at least one of the rail parts of the first rail and / or the second rail. By means of the handle section, the rail part in question can be gripped particularly easily and thus the rail parts can be mutually opposed to the force of the spring

Open position can be moved or rotated. The handle section projecting outwards can also be a surface section on the

act on the relevant rail part, which has a higher coefficient of static friction than the material of the rail †.

In order to be able to clamp the awning fabric particularly well, the rail parts of the first rail and / or the rail parts of the second rail can each have a holding section with an enlarged cross section at their free ends. The cross section can be designed such that the holding sections mutually facing sides have the largest possible contact area, which is in particular wider than the wall thickness of the adjacent sections of the rail file in cross section.

To optimize the half effect, the half sections of the first

Rail and / or the second rail on their mutually facing soaps have at least one elevation-increasing element. For example, at least one protruding projection can be arranged on the half section of a rail file, which projection is designed to protrude into a corresponding groove on the half section of the further rail part of this rail in order to hold an awning cloth arranged between them in a particularly secure manner. Alternatively or additionally, a covering made of a material with a high coefficient of static friction, such as a (moss) rubber material, can be provided on the sides facing one another. In a further embodiment, the neck sections can also have a zigzag shape on the sides facing one another, in particular with protruding edges that are sharp or slightly flattened.

In order to enable the awning fabric stabilization to be securely fixed to an awning, a stop element †, for example made of a rubber or plastic material, can be provided on the free end of the first rail and / or the free end of the second rail. The stop elements † prevent the rails from slipping, for example, from the awning housing or the crossbeam at the opposite end of the awning cover and enable the awning cover stabilization to be reliably clamped †.

Furthermore, an awning, in particular for a caravan or a motorhome, is claimed with an awning cloth, which is characterized in that the awning cloth stabilization described is attached to at least one edge section of the awning cloth. With an awning of this type, the awning fabric is particularly stable and wind noises, such as those which occur when the edges of the awning fabric flap, are avoided.

For particularly stable support of the awning fabric stabilization, it can be supported with the stop elements on the free end of the first rail and / or the second rail on a cross member of the awning or an awning housing †. In addition, the cross member can be compared to the awning housing be pre-tensioned so that the awning fabric stabilization is clamped between the cross member and the awning housing †.

Further special features and advantages of the invention result from the following description of a preferred exemplary embodiment with reference to the drawings. Show it:

Figure 1 is a perspective view of an awning fabric stabilization.

3 shows a cross section through the awning fabric stabilization of FIG. 1;

Fig. 4 is a perspective view of the awning fabric stabilization of Figure 1 in an open position and

5 shows a further detailed view † of the awning fabric stabilization from FIG. 1. In Figure 1, an awning † abilization 1 is shown, which can be used in particular in an awning on a caravan or mobile home. The awning fabric stabilization comprises a first rail 2 with two rail files 3a, 3b which can be moved relative to one another, between which an edge section of an awning fox can be clamped. In the first rail 2, a second rail 4 is mounted in a telescopic manner, so that the rails 2, 4 can be displaced relative to one another and thus the length of the awning fox stabilization 1 can be adjusted. The second rail 4 comprises two mutually movable rail parts 5a, 5b, with which a further edge section †† of the awning, preferably † an edge section †† adjacent to the edge section clamped by the first rail 2, can be clamped. A stop element 6a, 6b is arranged on the free ends of the rails 2, 4 facing away from the adjacent rails 4, 2. The stop elements 6a, 6b are designed for contact with a cross member of the awning or an awning housing / case and preferably consist † of a plastic or rubber material in order to prevent damage to the cross member or the awning housing and to be securely fixed by a high friction coefficient enable. The stop elements 6a, 6b can have a recess into which the respective end of the rails 2, 4 can be inserted, so that the stop elements 6a, 6b are held securely on the rails 2, 4. FIG. 2 shows a detailed view of the awning fox stabilization 1 from FIG. 1. As can be seen there, the rail parts 3a, 3b of the first rail 2 are mutually rotatably connected via a swivel joint 7. In addition, the rail parts 5a, 5b of the second rail 4 are mutually rotatably connected to one another via a further swivel joint 8. Through the rotary joints 7, 8, the rail parts 3a, 3b of the first rail 2 and

Rail parts 5a, 5b of the second rail 4 can be mutually rotated or pivoted from the shown folded position into an opened open position. The axes of rotation of the swivel 7, 8 are arranged parallel and offset from one another. The mode of operation is explained in more detail with reference to the following figures.

FIG. 3 shows a cross section through the awning fabric stabilization 1 from FIG. 1 in an overlap area between the rails 2, 4. As can be seen there, the swivel joints 7, 8 are formed in that one rail part 3a, 5a engages around the other rail part 3b, 5b in a form-fitting manner and the contact surfaces between the rail parts 3a, 3b and 5a, 5b in cross section, in particular in the form of a part circle are trained. Using the swivel 7, the identically designed swivel 7, 8 will be described in more detail below by way of example. In the case of the swivel joint 7, the free end of the rail part 3a facing the rail part 3b engages in cross section with a projection 9 on the rail part 3b which has a part-circular cross section †. Adjacent to the projection 9, a groove 10 is formed in the rail part 3b, which has a part-circular profile in cross section † and is flush with the part-circular cross section of the projection 9 †. The width of the groove 10 is slightly wider than the wall thickness of the rail part 3a at the end facing the groove 10, so that the rail part 3a can be inserted into the groove 10 and guided there in a form-fitting manner. By partially gripping the projection 9 and protruding into the groove 10, a positive rotary joint 7 is formed between the rail parts 3a, 3b and an unintentional loosening against one another is prevented.

The swivel joint 7 can be assembled in such a way that the rail parts 3a, 3b can be clipped onto the swivel joint 7 due to the elasticity of the material used for the rail parts 3a, 3b. Alternatively, it can also be seen before to slide the rail parts 3a, 3b together on the swivel joint 7 in the longitudinal direction. Especially when the rail parts 3a, 3b are made of aluminum, for example, and are therefore rather smaller than plastic Have elasticity and / or if the rail file 3a encompasses the projection 10 over a larger angular range in cross section †, in particular over an angular range greater than 180 °, a particularly stable swivel 7 is formed, which preferably † by pushing the rail parts 3a, 3b together in the longitudinal direction is to be assembled. The swivel joint 8 between the rail parts 5a, 5b is of identical design †, so that the description of the swivel joint 7 applies equally to this.

In order to telescopically support the rails 2, 4, a rail part 3b of the first rail 2 is connected to a rail part 5b of the second rail 4 so as to be longitudinally displaceable via a linear guide 11. In the embodiment shown, for example, the linear guide is formed by two mirror projections 12a, 12b on the rail part 3b of the first rail 2, each of which engages behind a guide 13a, 13b on the rail part 5b of the second rail 4. The projections 12a, 12b and the guides 13a, 13b preferably extend † over the entire length of the rails 2, 4.

In order to enable the rails 2, 4 to be mutually locked, the folding element † 14 shown schematically here is provided in the form of a locking screw which is guided in an internal thread in the rail part 3b and can be supported against the rail part 5b. This allows the rail parts 3b, 5b to be braced † and the linear guide 1 1 to be releasably locked †. In the longitudinal direction of the rails 2, 4, several such holding elements 14 can be provided.

In the rail parts 3a, 3b of the first rail 2 and the rail parts 5a, 5b of the second rail 4, a recess 15a, 15a or 16a, 1 6b is formed †, in which one end of a spring 17a, 17b is mounted. The springs 1 7a, 1 7b are leaf springs which are pretensioned in the curved position in order to mutually press the rail parts 3a, 3b and 5a, 5b into the shown closed position. The springs 17a, 17b can in particular be designed to be bistable †, so that from a certain opening angle of the rail parts 3a, 3b or 5a, 5b to one another, the spring force acts in the opposite direction † and the rail parts 3a, 3b or 5a, 5b into one Opening position †.

For easier gripping when opening, handle portions 18a, 18b projecting outward on the rail parts 3a, 5a in the form of in the longitudinal direction extending webs provided. In an embodiment not shown, such grip sections can also be provided on the further rail parts 3b, 5b.

In order to be able to clamp an edge section of an awning in a particularly reliable manner, the rail parts 3a, 3b of the first rail 2 and the rail parts 5a, 5b of the second rail 4 each have a holding section 19a, 19b at their free ends opposite the swivel joints 7, 8 or 20a, 20b. The holding sections 19a, 19b, 20a, 20b have a cross section which is enlarged in relation to the wall thickness of the adjacent sections of the rail parts 3a, 3b or 5a, 5b, so that in the closed position shown there is a particularly large contact area between the holding sections 19a, 19b of the first rail 2 or the holding sections 20a, 20b of the second rail 4 is reached. In order to additionally increase the holding force compared to an edge section of the awning fabric, the holding sections 19a, 19b of the first rail 2 and the holding sections 20a, 20b of the second rail 4 have elements which increase adhesion, such as ribs 21a, 21b, on the sides facing one another which protrude in the shown closed position in corresponding grooves, not numbered here, in the opposite holding section. In addition, a covering made of an adhesion-increasing material such as (sponge) rubber can be provided on the contact surfaces facing each other.

FIG. 4 shows a perspective illustration of the awning fabric stabilizer 1 from FIG. 1 in an open position. The bistable springs 17a, 17b, not shown here, of which several can be provided on the rails 2, 4 at a distance from one another in the longitudinal direction, hold the rail parts 3a, 3b, 5a, 5b in the position shown, so that a particularly simple one Edge section of an awning fabric between the holding sections 19a, 19b and 20a, 20b inserted and after positioning by folding the rail parts 3a, 3b and 5a, 5b can be firmly clamped. In the embodiment shown, the awning fabric is pressed by the ribs 21 a, 21 b on the holding sections 19a, 20a into the grooves 22a, 22b on the holding sections 19b, 20b for a particularly advantageous holding action.

As can also be seen from FIG. 4, the rail parts 3a, 3b of the first rail 2 and the rail parts 5a, 5b of the second rail 4 have a constant cross section in the longitudinal direction, since the swivel joints 7, 8 align with the

corresponding projections and grooves and the linear guide 1 1, the Recesses 15a, 15b and 16a, 16b, the handle sections 18a, 18b and the half sections 19a, 19b, 20a, 20b with the ribs 21a, 21b and grooves 22a, 22b extend in the longitudinal direction of the rails 2, 4. Such as rail parts formed from rail parts 3a, 3b, 5a, 5b are particularly easy to produce as extruded profiles, which enables inexpensive production from plastic or light metal such as aluminum.

FIG. 5 shows a further detailed view of the awning fabric stabilization 1 from FIG. 1. As can be seen from this representation of the end of the first rail 2 facing away from the second rail 4, the stop element 6b and also the stop element 6a on the second rail 4 are plugged onto the first rail 2 in order to enable particularly reliable fastening.

Like the upper rail part 5a at the free end of the second rail 4 shown in FIG. 2, the upper rail part 3a is also notched at the free end of the first rail 2, so that at the free end of the second rail 4 the lower rail part 5b and at the free end the first rail 2, the lower rail part 3b protrudes †. Advantageously, the rail part 3a at the free end of the first rail 2 is at least 8 cm, particularly preferably at least 10 cm, compared to the rail part 3b, and / or the rail part 5a is at least 2 cm compared to the rail part 5b at the free end of the second rail 4, particularly preferably at least 4 cm, arranged offset in the longitudinal direction. This ensures that the free end of the first rail 2 can be guided past the awning housing underneath a roller for the awning cover and does not line up with the roller and hinder it. In addition, the free end of the second rail 4 can be supported particularly well on the cross member at the free end of the awning fabric also on an area of the cross member which is set back from the storage of the awning fabric on the cross member.

In a preferred embodiment, the awning fabric stabilization shown

1 attached to an awning cover of an awning in a top view of the rolled-out awning on the left (longitudinal) side, so that the first rail with the larger cross section is attached to the awning housing and that in the first rail

2 mounted second rail 4 with the smaller cross section on the

support the projecting cross member of the awning †. The awning fabric stabilization for the opposite edge section of the awning fabric can be produced particularly simply in that the second rail 4 in the case in FIG The arrangement shown does not protrude to the left from the first rail 2, but is shifted so far relative to the outer first rail 2 that it protrudes at the opposite end shown in FIG. 5. The stepped upper rail parts 3a, 5a are then only to be shifted to the lower rail parts 3b, 5b in such a way that they are positioned flush with the opposite end. Adapted stop elements 6a, 6b can be mounted on the free ends of the first rail 2 and the second rail 4. In this way, a mirror-image awning fox stabilization for both edge regions of the awning fox can be created particularly easily with components identical to the stop elements 6a, 6b.
