[0083] FIG. 7 schematically shows an embodiment of a screen according to the invention in a transport position.
[0084] FIGS. 8a-d schematically show sections of an embodiment of a vehicle according to the invention in a transport position.
[0085] FIGS. 9a-b schematically show sections of an embodiment of a screen or vehicle according to the invention with a rain cover.
[0086] FIG. 1a shows a screen 1a in a set up state along a straight path. The screen 1a has eight frames 2, which are connected to one another via joints 3. One of the two outer frames 2 is connected via a spacer 4 to two securing elements 5, each of which has a recess (not shown) for connection at a suitable point, e.g. on a hook, on the exterior of a vehicle. The frame 2 is connected to the spacer 4 via joints 6. The spacer 4 has two diagonal struts 7 for increasing stiffness. The frame 2 connected to the spacer 4 is connected to a screen element 8 made of metal, while each of the remaining frames 2 is connected to a screen element 8 made of net vinyl having three lamellae 8a that can be displaced relative to one another. The lamellae 8a are connected to the respective frame 2 via elastomer bands 9 (shown in FIG. 2c). Two opposing, collapsible support legs 10 are secured to each second frame 2, so that the set up screen 1a is supported in a V-shape (more precisely, inverted V-shape). Furthermore, a support wheel 11 is secured to the frame 2 via an extendable rod 12 on every second frame 2. The support legs 10 and support wheels 11 are arranged alternately on the frames 2. The arrangement of the frames 2 in FIG. 1a along a straight line allows an additional connection of each two frames 2 by means of a drop bar latch 13, which is secured to each second frame 2, so that the frames arranged in a region between two support legs 10 are rigidly connected to one another.
[0087] FIG. 1b shows a further screen 1b in the set up state. It is constructed similarly to the screen 1a shown in FIG. 1a, but has nine frames 2, which are arranged in a pivoted manner with respect to one another. The number of joints 3 between the frames 2 also differs from that of the screen 1a shown in FIG. 1a.
[0088] FIG. 1c shows a section of a screen 1c that is substantially constructed like the screen 1a shown in FIG. 1a. However, the securing element 5 differs from those shown above in that it has a 3-finger gripper.
[0089] FIG. 2a shows a portion of a screen. A frame 2 is shown, which is connected to a screen element 8, which has three lamellae 8a. Each of the lamellae 8a is connected to the frame via two separate elastomer bands 9. Accordingly, in each case three elastomer bands 9 are tensioned in the immediate vicinity of two mutually opposite sides of the frame 2 parallel to these sides of the frame 2 (see FIG. 2c). In this case, in each case two elastomer bands 9 tensioned on opposite sides of the frame 2 form an elastomer band pair. Each lamella 8a is held by a pair of elastomer bands, so that the lamellae 8a are arranged offset from one another in the frame 2 and are therefore displaceable relative to one another. In FIG. 2a, the lamellae 8a are arranged
[0090] One above the other, which can facilitate the set up of the screen by enabling the reduction of an attack surface for wind (quasi the sail surface) and the associated wind load, and can also facilitate the simple temporary opening of the already set up screen, e.g. for a person to climb through. Parts of joints 3 for connection to other frames 2 are secured to two sides of the frame 2. Furthermore, the illustrated part of the screen shows a support wheel 11, which is secured to the frame with an extendable rod 12. On one side of the frame 2 adjoining the two sides to which parts of joints 3 are secured, recesses 14 are provided for receiving corresponding protrusions of drop bar latches 13 secured to adjacent frames 2.
[0091] FIGS. 2b-c show a part of a further screen or a section thereof. A frame 2 is shown, which is connected to a screen element 8 having three lamellae 8a. Each of the lamellae 8a is connected to the frame via two separate elastomer bands 9. Accordingly, in each case three elastomer bands 9 are tensioned in the immediate vicinity of two mutually opposite sides of the frame 2 parallel to these sides of the frame 2. In this case, in each case two elastomer bands 9 tensioned on opposite sides of the frame 2 form an elastomer band pair. Each lamella 8a is held on the two narrow sides by a pair of elastomer bands, so that the lamellae 8a are arranged offset from one another in the frame 2 and are therefore displaceable relative to one another. Due to the adjacent arrangement of the lamellae 8a according to FIGS. 2b-c, an area of operation can be well shielded. Parts of joints 3 for connection to other frames 2 are secured to two sides of the frame 2. On a side of the frame 2 adjacent to these two sides, recesses 14 are provided for receiving corresponding protrusions of drop bar latches 13 secured to adjacent frames 2 (shown, for example, in FIG. 1c) . The part of the screen shown in FIG. 2b also shows a support wheel 11 secured to the frame 2 via a rod 12. A support leg 10 is also provided, which rests against the frame 2 and is articulatedly connected to it via a clamp 15.
[0092] FIG. 3a illustrates the screen of FIG. 2b with the support legs 10 unfolded. This results in a V-shaped (more precisely, inverted V-shaped) support of the frame 2. A strut 16 is provided between the frame 2 and each of the support legs 10. The support legs 10 have a flattened, collapsible support surface 17, which is folded out in the set up state of the screen in order to ensure good stability on a hard surface (e.g. asphalt). The support legs 10 are displaceable relative to the frame 2 and, due to their geometric configuration (see FIGS. 3b-c), can be held in a certain position by means of screws 18 provided in the frame 2.
[0093] FIGS. 3b-c show detailed views of the part of a screen shown in FIG. 2c in a transport position. Two opposing support legs 10 rest against the frame 2. The support legs 10 have an acute-angled recess 19 at both ends and, due to this geometric configuration, are held by screws 18 secured to the frame 2. FIG. 3b illustrates an upper region of the frame 2, wherein the connection of the support legs 10 to the frame 2 can be seen via a clamp 15. The clamp 15 has two hinge joints (not shown) to which the support legs 10 are connected, so that the support legs 10 can be folded out in an set up state of the screen. FIG. 3c illustrates a lower region of the frame 2, wherein it can be seen that each of the support legs 10 has a flattened support surface 17. Each of the support surfaces 17 can be rotated relative to the respective support leg 10 via a hinge joint 20 and is folded in for transporting the screen.
[0094] FIGS. 4a-b show various perspective views of a part of a screen in a transport position, frames 2 connected to one another via joints 3 being collapsed. Each frame 2 is connected to a screen element 8. Each screen element 8 has three lamellae 8a, which are connected to the frame 2 via elastomer bands 9. In FIGS. 4a-b, the lamellae 8a of all frames 2 are arranged one above the other. Provided on each frame 2 is a support wheel 11, which is secured to one side of the frame 2 via an extendable rod 12. The frames also have recesses 14 for receiving drop bar latches 13 (shown, for example, in FIG. 1c) of adjacent frames.
[0095] FIGS. 5a-b show a vehicle 21 or a section thereof, to the rear side 22 of which (illustrated in FIGS. 6a-c) a screen 1d is secured in a transport position. Secured in the region of the floor and roof 23 of the vehicle 21 are guide rails 24, which are arranged in the immediate vicinity of two longitudinal sides 25 and the rear side 22 of the vehicle 21 and are curved in corner regions 26, a curve radius being 40 cm. Each guide rail 24 is correspondingly U-shaped. To increase stiffness, the guide rails 24 have struts 27 arranged normal thereto, which are secured to the roof 23 and/or to the floor of the vehicle 21. Sections 28 of the guide rail 24 secured to the floor of the vehicle 21 in the region of the wheels 29 of the vehicle 21 are removable so as not to impede a wheel change. As can also be seen from FIGS. 5a-b, the screen 1d is connected to the two guide rails 24 via two securing elements 5, each of which has a 3-finger gripper 30 (shown schematically). The connection is made by receiving the guide rails 24 in circular or elliptical recesses of the 3-finger grippers 30 and then screwing them together. In order to enable movement of the screen 1d along the curved corner regions 26 of the guide rails 24, the 3-finger grippers 30 comprise an elastomer, so that the individual fingers of the 3-finger gripper 30 can be stretched relative to one another. Frames 2 connected via joints 3 are collapsed for transporting the screen 1d. The spacer 4 is arranged pivoted by 90 with respect to the frame 2, to which it is connected via joints 6, so that the screen 1d rests directly against the rear side 22 of the vehicle 21. Each second frame 2 has a drop bar latch 13 for connection to adjacent frames 2. Recesses 14 for receiving drop bar latches 13 are also provided on the frame 2. FIG. 5b also shows two tensioning elements 31 in the form of tensioning clamps secured to the frame 2 in order to prevent unintentional pivoting of the frames 2 relative to one another in the transport position.
[0096] FIGS. 6a-c show the vehicle 21 already shown in FIGS. 5a-b with the screen 1d or sections thereof during a process of installing the screen 1d at an area of operation. The screen 1d is connected to guide rails 24 of the vehicle 21, which are secured to a floor and a roof 23, via a respective securing element 5, which has a 3-finger gripper 30 (shown schematically). In contrast to a transport position (see FIG. 5), a spacer 4 and a frame 2 connected thereto via joints 6 are pivoted with respect to one another. In order to set up the screen 1d, collapsed frames 2 connected to one another via joints 3 can be at least partially unfolded. As a result, the screen 1d can be brought into one of the positions shown in FIGS. 1a-b. Since the guide rails 24 are U-shaped, the screen 1d can be set up starting from one of the two longitudinal sides 25 or the rear side 22 of the vehicle 21, which allows great flexibility. Thus, in FIG. 6a, the screen 1d is arranged on a longitudinal side 25 of the vehicle 21 in the region of exterior mirrors, in FIG. 6b on a longitudinal side 25 of the vehicle 21 in the region of wheels 29, and in FIG. 6c in a curved corner region 26 of the guide rails 24.
[0097] FIG. 7 shows a further screen le in a transport position. The screen le has two securing elements 5 for securing to a vehicle. The securing elements 5 are designed as 3-finger grippers 30, wherein the outer two fingers 32 are designed to be extendible (see detail view in FIG. 8b). Each of the three fingers 32 is rotatably secured to a separate carriage 33. As a result, the screen le can be displaced along curved corner regions 26 of a guide rail 24 of the vehicle (see FIGS. 8a-d). The screen le shown in FIG. 7 has lamellae 8a, which are displaceable relative to one another by means of guide rails (not shown) provided in frame 2.
[0098] FIGS. 8a-d show a vehicle 21 to whose rear side 22 (illustrated in FIGS. 6a-c) the screen le already shown in FIG. 7 is secured in a transport position, or parts thereof. As shown in the detail view in FIG. 8b, the outer two fingers 32 of the 3-finger gripper 30, which are configured to be extendible, have an inner portion 34 that is extendible from an outer portion 35 to vary the length of the outer two fingers 32. Each of the three fingers 32 is secured to a separate carriage 33 with a swivel joint (not shown). The 3-finger gripper 30 is also secured to the securing element 5 by means of a swivel joint (not shown). The carriages 33 are secured by means of screw connections (not shown) to guide rails 24, which are arranged in the region of the floor and the roof 23 of the vehicle 21. In FIG. 8d, the vehicle 21 is only indicated by means of the guide rails 24 and wheels 29 in order to show the securing of the screen le to both guide rails 24.
[0099] FIG. 9a shows a section of a screen 1f having a rain cover 36 secured to a frame 2. The screen 1f is in the set up state. The rain cover 36 is arranged at an angle of approximately 90 to the frame 2 and can protect persons from rain at the area of operation. FIG. 9b shows a section of a vehicle 21 in a transport position, to which the screen 1f is secured. The rain cover 36 can protect the screen 1f from rain in the transport position.
