Description

The invention relates to a sunshade or wind protection device with a plurality of longitudinal bars, which have longitudinal dividing bars coupled on the longitudinal side, with a plurality of transverse bars, which have longitudinal dividing bars coupled on the longitudinal side, with at least one covering unit which is stretched between the longitudinal bars, the transverse bars at least partially connecting the longitudinal bars to one another and wherein at least one crossbar has at least one tension adjustment device for adjusting the tension of the clothing unit in the transverse direction.

Such sun protection or wind protection devices usually use fabrics such as sails or cloths as the covering unit, which are stretched by the rods. In order for the device to provide shade and wind protection as intended, the covering unit between the longitudinal bars must be stretched to a certain extent. In order to achieve this, the longitudinal bars are often threaded into tabs or similar connecting loops of the covering unit and the longitudinal bars are then spread accordingly with the cross bars in order to achieve the desired tension effect. The longitudinal rods thus preferably carry the covering unit, while the transverse rods define the positions of the longitudinal rods in relation to one another. It can of course also be provided that the transverse rods are connected to the covering unit.

The longitudinal rods and the transverse rods have partial rods which are coupled at their ends, that is to say are coupled on the longitudinal side. These partial rods can be connected, for example, via connecting sockets into which they are inserted. This allows for easy transportation in an unassembled state by allowing the device to be folded very small. If the dividing rods are coupled longitudinally, they can transmit force. For this purpose, the longitudinal bars and transverse bars are preferably designed to be elastic in order to form defined shapes under tension. For example, arches or domes can be formed. The connecting sockets usually have centrally arranged stops inside, which allow the partial rods to penetrate into the connecting socket only up to a defined depth. This defines an end position of the sub-rods relative to the connecting sleeve in an assembled state.

In order to be able to adjust the degree of tension better, especially when different covering units are ready to be exchanged, tension adjustment devices are known which have tension adjustment devices at the end of the crossbars exhibit. Often these tension adjustment devices are designed as axial screw connections of connecting elements for connection to the longitudinal rods and the transverse rods, as for example in FIG US 9,163,394 B1 described. By rotating the connecting elements, the length of the crossbars and thus the distance between the longitudinal bars can be increased or decreased somewhat in order to achieve greater tension through the change in length. The disadvantage, however, is that the connecting elements of the crossbars have to be detached from the longitudinal bars in order to change the length. In addition, adjustment is difficult when the device is already largely or fully assembled since, as described, the stringing unit is typically connected to the longitudinal bars and adjustment of these areas is difficult for the user to access. Due to the connection with the longitudinal rods, the covering unit hinders access to the tension adjustment device, since this is generally not or only slightly elastic. In addition, these tension adjustment devices are usually not elastic or have a different elasticity than the other parts of the dividing bars. Accordingly, when force is applied to the crossbars, there is an irregular deformation of the crossbar. This is not visually appealing. In addition, crossbars with several crossbars are known, through which the width of the device can be adjusted. For example, in the U.S. 5,240,020 discloses a system describing spring-loaded snaps for width adjustment. However, such a system can only be used for the rough adjustment of the width, a fine adjustment to achieve the desired tension is not possible.

The object of the invention is therefore to avoid the disadvantages mentioned and to provide a sun protection or wind protection device with improved operability according to claim 1 . Preferred features of the invention are set out in the dependent claims.

This object is achieved according to the invention in that the tension adjustment device is removed from the longitudinal rods, is arranged between two transverse dividing rods of the transverse rod and that the tension adjustment device has a bushing which couples two transverse dividing rods to one another on the longitudinal side and the bushing has at least one thread for connecting to a corresponding thread of a first Cross dividing bar having two cross dividing bars.

This removes the tension adjuster from the longitudinal bar, making it easier for the user to access. This facilitates adjustability since the stringing assembly can be more easily pushed away from the tension adjuster when it is farther from the longitudinal bar. This goes like this far that the setting can even be done with just one hand.

The longitudinal dividing rods and/or also the transverse dividing rods are preferably connected to one another via elastic bands running inside the rods. The partial rods can be detachably connected to one another using connecting bushes, but the individual parts cannot be lost thanks to the elastic bands.

It is particularly advantageous if the clamping adjustment device is arranged approximately halfway along the crossbar. This also enables the crossbar to have a uniform shape when it is bent.

Furthermore, the invention provides that the clamping adjustment device has a bushing which couples two transverse dividing bars to one another on the longitudinal side and the bushing has at least one thread for connecting to a corresponding thread of a first transverse dividing bar of the two transverse dividing bars. This bushing preferably receives the ends of the first and second cross-section bars and thus acts at the same time as a connecting element of the two cross-section bars, coupling them longitudinally thereto. When the bushing is rotated, its threads engage the threads of the first transverse dividing rod, which thereby moves further into the interior of the bushing and thus changes the position of the first dividing rod relative to the bushing. The second partial rod, on the other hand, preferably rests against a stop on the bushing and is therefore in a defined position relative to the bushing. Screwing the bushing together thus results in an adjustment of the distance between the first and second transverse dividing rods and thus in a change in the length of the transverse rod. Such an embodiment is particularly advantageous since it can only be adjusted from the outside by turning the bushing, which is particularly simple and easy to handle. In addition, the mechanism is not visible from the outside and is not visually disturbing and is protected from external mechanical or chemical loads. Preferably, therefore, the bushing is threaded internally of the bushing while the first cross-sectional bar is inserted into the bushing. Alternatively, the thread can also be arranged on the outside of the bushing and a transverse dividing rod can have a recess at the end facing the bushing, which has a corresponding thread.

In a preferred embodiment it is provided that the thread of the first transverse dividing rod is arranged in the region of the end of the first transverse dividing rod facing the socket and a second transverse dividing rod has no thread at the end of the second transverse dividing rod facing the socket. The second dividing bar is preferably flat at its end facing the socket.

It is particularly advantageous if the thread of the bushing has a stop against which a second transverse dividing rod rests in the assembled state. A particularly compact and easy-to-manufacture version of the socket is thus found. The socket can be designed as a tube, in the interior of which a constriction is provided, in which the thread is arranged. The constriction thus acts as a retaining element for the thread and the end wall of the constriction acts as a stop for the second cross-dividing rod.

Furthermore, it can be provided that the thread of the bushing is arranged in the area of approximately one third of the longitudinal extension of the bushing. This leaves a particularly large amount of space for arranging the second transverse dividing rod in the socket, which ensures a particularly stable connection with it. This is not necessary for the first transverse dividing rod, since this is in any case sufficiently firmly connected to the bushing by the thread. This allows the socket to be made shorter.

If the thread of the first transverse dividing rod has an outer diameter d, and the second transverse dividing rod has a recess at least in the region of the end facing the bushing, the inner diameter D of which is larger than the outer diameter of the thread, the first transverse dividing rod can be partially accommodated by the second transverse dividing rod , when the threads mesh so deeply that the threads of the first cross-divider bar reach the second cross-divider bar. In this way, the thread of the first transverse dividing rod can also be made particularly long and the length adjustment of the transverse rod can extend over a particularly large area.

In order to be able to use different clothing units of very different sizes, it can be provided that at least one cross bar has at least one extension part bar, which can be coupled to at least one cross part bar on the longitudinal side. With these removable extension parts, the length can be greatly increased.

If the transverse bars are at least partially connected to the longitudinal bars by means of elastic gripping clamps, the connection of the transverse bars to the longitudinal bars can be easily established. The connection via the gripping clamps enables the cross bars to be moved along the longitudinal bars on the one hand and easy mounting and detaching on the other. To do this, the gripping clamp is pressed against the longitudinal rod with force, as a result of which the clamp bends up elastically and thus encompasses the longitudinal rod. For this purpose, the gripping clip preferably has a cylindrical part which connects to the crossbar and one at least partially elastic gripping part, which can partially encompass the longitudinal rod. This also results in rotatability about the longitudinal axis of the longitudinal rod.

Furthermore, it can be advantageous if a head bar and a foot bar connect at least two longitudinal bars to one another at their ends and the head bar and foot bar each have a connecting link for attaching the sunshade or wind protection device to a suitable base such as a sun lounger, with the connecting links around a Axis of rotation can be pivoted transversely to the longitudinal axis of the head or foot rod. This means that the device can be ideally aligned depending on the sun or wind conditions and adjusted at any time. The connecting links are preferably also pivotable about a tilting axis, the tilting axis being arranged substantially parallel to the head or foot bar, depending on which bar the connecting link is arranged on. Alternatively, the connecting member can also be connected to the base in such a way that it can pivot about a tilting axis, for example via a clamp connection.

Connecting links preferably comprise toothed, interlocking rotating parts which in a relaxed position can be rotated relative to one another and in a tightened position pressed against one another and thus locked in place to prevent unwanted twisting while still permitting good adjustability.

The head and foot bars can be designed like the cross bars, but can also be made stronger and mechanically stronger, especially if they are intended to bend the longitudinal bars into defined shapes. The head and foot bars, like the crossbars, may have tension adjusters.

Side parts are preferably also provided, which have the longitudinal rods which are not connected to the other longitudinal rods via transverse rods, but are preferably only connected at their ends to the other rods, particularly preferably movably. A side part that falls in the direction of the ground can thus be formed in that gravity pulls this longitudinal bar in the direction of the ground.

Provision can be made for the longitudinal rods or the head or foot rods to have connection options for wheels, rollers, runners or similar means of transportation. Such means of transportation can be attached to the device in order to improve the sun or wind sail in the assembled state to be able to transport. In the simplest case, holes can be provided in the longitudinal rods in the area of their ends, through which links such as screws or axles of the means of locomotion can be guided.

1 shows a first embodiment of a sun protection or wind protection device 1 without a covering unit. In this case, a composite rod is formed from two longitudinal rods 2a, three transverse rods 6 and one head rod 15 and one foot rod 15, which can tension a covering unit. The longitudinal rods 2a are parallel to one another and composed of longitudinal dividing rods 2 which are connected to one another on the longitudinal side via connecting bushes 9 . The covering unit is connected to the longitudinal rods 2a and stretched between them. The transverse rods 6, which are normal to the longitudinal rods 2a and are parallel to one another, each have two transverse dividing rods 66, with clamping adjustment devices 11 being arranged in the middle of the transverse rods 6, which have bushings 10 which connect the transverse dividing rods 66 to one another. The head and foot bars 15 do not have tension adjustment devices, but can also have such in alternative embodiments. The head and foot bars 15 are U-shaped and receive the ends of the longitudinal bars 2a. The crossbars 6 are connected to the longitudinal bars 2a via gripping clamps 7 . In alternative embodiments it can be provided that more than two transverse dividing rods 66 are provided, with several tension adjustment devices 11 being provided between these. By adjusting the tension adjustment devices 11, the lengths of the transverse rods 6, and thus the distance between the longitudinal rods 2a and thus the tension in the transverse direction q, can be adjusted. In the area of the ends of the longitudinal bars, these have bores 16 which correspond to bores in the foot bar 15 in the assembled state and fall over each other. Skids or wheels can be attached to these to facilitate transport.

In 2 the span adjuster 11 is shown in more detail. This has a hollow-cylindrical bushing 10 which has a thread 12 on the inside, the threading being arranged on a base 13 which has shoulders in the direction of the openings of the bushing 10 which can serve as a stop 14 . The thread 12 is arranged approximately at the level of one third of the overall length L of the bushing 10 . A first transverse dividing rod 66a has at one end facing the bushing 10 a thread 67 which corresponds to the threading 12 of the bushing 10 and can be screwed thereto. Thus, when the bushing 10 is rotated by the user, the first cross-piece bar 66a slides into or out of the bushing 10. On the opposite side of the bushing 10 there is a second transverse dividing rod 66b which is designed as a hollow tube. The inside diameter D of the resulting recess is larger than the outside diameter d of the thread 67 . When the threads 67, 12 are rotated fully into one another, an edge of the first cross-dividing rod 66a also rests against a stop 14.

3 shows a gripping clip 20 which can establish a connection between a transverse rod 6 and a longitudinal rod 2a. For this purpose, the crossbar 6 can be inserted into the recess of the cylindrical part 21 . For connection to the longitudinal rod 2a, the elastic gripping part 22 of the gripping clip 20, which has the shape of a part of a hollow cylinder, is pressed against the longitudinal rod 2a. The gripping part deforms elastically and grips the longitudinal rod 2a. This enables a stable, but if necessary detachable, connection which also enables rotation about an axis x corresponding to the longitudinal axis of the gripping part and the longitudinal rod 2a.

4 shows a connecting link 30, which has a first connecting part in the form of a cable clamp 32 for grasping the foot or head bar 15 and a second connecting part in the form of a grip 31 for connecting to a sun lounger, a railing, a carabiner or other base driven into the ground Having attaching the device. Gripper 31 and cable clamp 32 are connected via a screw axis 33, with gripper 31 and cable clamp 32 each having a rotary part designed as a toothed plate 34 with teeth or alternatively other fixing means. In the position shown, the tension clip 32 and gripper 31 can be rotated or pivoted relative to one another about the screw axis 33 - which defines the axis of rotation y - and thus transversely to the longitudinal axis of the foot rod 15 or head rod 15. If the screw axis 33 is screwed into a corresponding thread in the gripper 31 via a handle 35, thus, on the one hand, the tension clamp 32 is closed and thus engaged with a foot rod 15 or head rod 15 (not shown) arranged in it. In addition, the toothed plates 34 are pressed together, the teeth are engaged and the rotational position of the gripper 31 relative to the cable clamp 32 is fixed. This means that the rotary position can be freely selected in the open state, but fixed in the closed state, thus preventing unintentional adjustment. In this case, the tension clamp 32 and/or the gripper 31 can allow rotation about another axis, either about the longitudinal axis of the head or foot rod 15 or about the element surrounding the gripper 31 .

figure 5 shows part of an alternative embodiment of a first connecting part of the connecting link 30. This part thereby represents one half of a pulling clip 32, which has a semi-cylindrical recess 36 around it to receive the head or foot rod 15 and together with a corresponding counterpart, which is preferably in the Essentially shaped like this part. It preferably has another similarly shaped recess with a different diameter so that it can also be used for head or foot bars 15 of different dimensions. A bore 37 passes through the part through which an axle can be passed which can connect the counterpart described and a second connecting part to the part. A round toothed plate 34 is arranged around the bore, which can be brought into engagement with a corresponding toothed plate of the second connecting part. The part has a semi-circular shape, which makes it easy for a user to grasp and adjust the angle easily.

Such an embodiment with interlocking tooth plates allows for good adjustability. Alternatively, an embodiment may provide an axle which pivotally connects a first connection portion of the link 30 connectable to the head or foot bar 15 to a second connection portion of the link 30 for connection to the appropriate support. A locking body such as a ball is pressed onto the axle by a spring element, thereby preventing unwanted twisting caused by wind or other external forces. The spring force is only overcome and the device can be pivoted when sufficient force is applied, such as by the user's hand. The axis can have surface changes such as indentations or projections, at least in the region of the locking body, in order to improve the connection to the locking body. The force of the spring can preferably be adjusted by an adjusting screw. In this way, a user can initially determine how much force is required to pivot the device by adjusting the set screw.
