Description

[0001] Mobile privacy screen

[0002] The invention relates to a mobile privacy screen for mounting on a means of transport, in particular on a mobile means of transport, in particular on or in a vehicle, wherein the mobile privacy screen has a first privacy screen element and a second privacy screen element, wherein both privacy screen elements are surface elements with a structurally predefined main extension plane, wherein the second privacy screen element is movably connected to the first privacy screen element, wherein the mobile privacy screen has a support, wherein the support is configured for lateral support of the mobile privacy screen at at least 10% of the height of the second privacy screen element. The mobile privacy screen can also have multiple supports for support on the ground.

[0003] Mobile privacy screens are already known in the prior art. For example, EP 3428 343 Bi discloses a screen for shielding against accidents, comprising a support structure consisting of one or more support elements with vertical support posts, covered or covered with a sheet of opaque material, and held in feet in the form of elongated panels. To erect this screen, the feet are first set up separately, and then the support elements are anchored into them.

[0004] A mobile privacy screen for mounting on a vehicle is already known from WO 2009 / 121468 Ai. The barrier shown therein features roller supports to facilitate the movement of the side walls from a folded to an unfolded state. For lateral support, telescopic stiffening elements are provided between a base frame and each of the barrier's end side walls, which structurally support the unfolded barrier in a fully extended position.

[0005] A disadvantage of the known devices is that setting up the supports during the installation of the privacy screen is relatively complex and consumes valuable time, especially in emergency situations. In the known barrier designed for mounting on a vehicle, the lateral supports are also projecting, requiring the barrier to be erected at a corresponding distance from the site of use or requiring a large amount of space outside the barrier, for example, in the case of a traffic area. The object of the invention is to at least mitigate the disadvantages of the prior art.

[0006] The invention provides that the support is extendable along a support axis arranged parallel to the main extension plane of the second privacy screen element and has a base part that can be pivoted about the support axis. In this context, lateral support of the mobile privacy screen at at least 10% of the height of the second privacy screen element means a corresponding normal distance (i.e. of at least 10% of the height of the second privacy screen element) of the outermost point of a support side of the base part from the main extension plane of the second privacy screen element in a fully extended position of the support. The base part can thus remain permanently connected and coupled to the privacy screen elements and therefore does not have to be set up separately in a separate work step, but can rather be brought into the desired operating position together with the privacy screen elements. Extending the support, for exampleThe downward tilt allows for adjustment of the distance of the privacy screen elements from a potentially uneven surface. The pivoting of the base section relative to the support axis allows for adaptation to the conditions, such as the surface or the installation site. The mechanism for extending and pivoting the support can, for example, be designed to allow manual operation, allowing the privacy screen to be supported manually during installation.

[0007] The base section can be formed, for example, by an elongated structural element in the region of an end of the support remote from the second privacy screen element, wherein the structural element forms a right angle with the support axis. The base section can be designed to be flat, for example, plate-shaped. This shape of the base section contributes to the support being safely rolled over by a car tire. A structure or covering can additionally be provided on a support side of the base section to increase friction with the ground and prevent the base section from slipping when rolled over.

[0008] In a preferred embodiment, the support has a height adjustment mechanism with which the support can be fixed at a desired height (distance from the ground) or in a transport position.

[0009] The height adjustment mechanism preferably includes a rack arranged along the support axis and a handle. The locking and unlocking of the height adjustment mechanism preferably occurs by folding the handle up or down. The rack is preferably connected to the support. The handle is preferably connected to a sleeve that encloses the support axis of the support. The handle can preferably be folded up and down about a horizontal pivot axis. The handle preferably has a gear element at the end facing the support axis, which is toothed with the rack when the height adjustment mechanism is in a locked position. The support can thus be fixed at a specific height by engaging the gear element with the rack after the support has been extended, thus toothing it.Specifically, when unlocking the height adjustment mechanism from a transport position, the teeth are released by a lever movement of the handle. The support can then be rotated around the support axis, pivoting the foot section outward, and the support can be adjusted to the desired height. The height adjustment mechanism can then be locked again by folding up the handle.

[0010] Preferably, when locking the height adjustment mechanism, the support is pressed downward relative to the second screen element, so that the second screen element is raised upward when the support is placed on a solid surface. Preferably, the support is pressed downward relative to the screen element by 0.5-5 cm, more preferably by 1-3 cm. The downward movement of the support relative to the screen element preferably occurs by the gear element of the handle engaging the rack during a semicircular upward movement of the handle.

[0011] Preferably, the height of the support can be fixed between a fully retracted and a fully extended position essentially at any height level predetermined by the rack.

[0012] Preferably, the support bearing on the frame has a spring which is under tension when the privacy screen is in its transport position and presses the support into a locking position. In the case of a height adjustment mechanism as described above, the support is pressed downwards relative to the bearing when locked, so that at least part of the relative movement between the support and the second privacy screen element is absorbed by the bearing, in particular by a spring of the bearing. After the height adjustment mechanism has been released, the support can be rotated from the transport position into an extendable position by relaxing the spring. Even when the support is in its extended position and locked with the height adjustment mechanism, the spring absorbs the force transmitted from the support to the privacy screen element. The spring can therefore preferably be designed to absorb at least the weight of the second privacy screen element.

[0013] The pivoting of the base section back into the transport position can be limited by a stop element, so that the base section can essentially only pivot further than parallel to the main extension plane of the second screen element. The stop element is attached, for example, to a frame of the screen element. The base section preferably has an opening that can accommodate the stop element when the base section is in the transport position. Preferably, exactly two such stop elements are provided to prevent over-rotation of the base section or the support.

[0014] A privacy screen element that is first erected by pivoting and extending the support preferably has a first auxiliary support. The first auxiliary support is preferably located on the side of the privacy screen element that faces an outer end of the mobile privacy screen. When erecting the privacy screen, the first privacy screen element is preferably pivoted out only far enough in a first step to allow the auxiliary support to extend to the ground. Preferably, in a second step, the auxiliary support is extended to the ground so that it bears at least part of the weight of the privacy screen element. The privacy screen element can then be pivoted out further as described above and erected by releasing and extending the support.The first auxiliary support makes it easier to set up the privacy screen, as the weight does not have to be held manually when the support of the privacy screen element is extended in order to fully extend the support.

[0015] The auxiliary support is preferably extendable in a manner analogous to the support described above and preferably does not have a foot section. The auxiliary support preferably has a height adjustment mechanism as described above. The auxiliary support preferably also has a spring-loaded bearing as described above.

[0016] The mobile privacy screen preferably has a second auxiliary support, which can similarly facilitate dismantling the screen if the screen has been removed from the means of transport. The second auxiliary support is preferably located on a privacy screen element that is the second to last to be erected or the second to be dismantled. Before dismantling the privacy screen, the second auxiliary support is preferably extended so that when the support of the first dismantled privacy screen element is retracted, it can bear the weight of this privacy screen element and lift this privacy screen element for reassembly on the means of transport. The second auxiliary support is also preferably extendable in a similar manner to the support described above and preferably does not have a base section. The second auxiliary support preferably has a height adjustment mechanism as described above. The second auxiliary support preferably also has a spring-loaded bearing as described above.

[0017] Preferably, when locking the height adjustment mechanism, the second auxiliary support is pressed downward relative to a frame of the privacy screen element, as described above in connection with the support. This preferably allows the privacy screen element to be removed first to be raised so high that its lower edge is above the loading level of a means of transport onto which the privacy screen is to be loaded, and the means of transport, for example, a roll container, can be easily pushed underneath the privacy screen element. Manual lifting of the privacy screen element is not necessary.

[0018] In a variant of the present disclosure, the second privacy screen element can have a first privacy screen panel and a second privacy screen panel as well as a frame, wherein the second privacy screen panel is movably connected to the frame, wherein the second privacy screen panel is additionally magnetically held to the frame in a closed position of the second privacy screen element. The magnetic holder of the movable second privacy screen element in the closed position can yield under mechanical stress, for example due to occurring wind forces, and thus reduce the overall lateral forces acting on the privacy screen and thus increase its stability. The movement of the second privacy screen panel is preferably guided by at least one rail. Alternatively or in addition to the magnetic holder, the rail can have one or more recesses (e.g.in the form of recesses in the rail, as holding or locking positions) into which the second privacy panel can engage in a specific position, preferably at least in a closed position and an open position. Between the open and closed positions, at least one further intermediate position can be provided, into which the second privacy panel can engage.

[0019] Due to these advantages, the disclosure also relates generally and independently of any support to a mobile privacy screen for mounting on a means of transport, in particular on a mobile means of transport, in particular on or in a vehicle, wherein the mobile privacy screen has a first privacy screen element and a second privacy screen element, wherein both privacy screen elements are surface elements with a structurally predefined main extension plane, wherein the second privacy screen element is movably connected to the first privacy screen element, wherein the second privacy screen element has a first privacy screen field and a second privacy screen field and a frame, wherein the second privacy screen field is movably connected to the frame, wherein the second privacy screen field is additionally held magnetically on the frame in a closed position of the second privacy screen element.

[0020] In the described variant, the second privacy screen can optionally be held in place in the open position of the second privacy screen element by magnets and / or by the recess described above on the frame. The holder in the open position prevents the second privacy screen element from closing automatically, for example, during transport or installation. It may be desirable, especially before installing any supports, to minimize the wind-exposed surface of the privacy screen element to facilitate installation in windy conditions.

[0021] According to a further embodiment of this variant, the second privacy screen element can have a third privacy screen panel, wherein the third privacy screen panel is movably connected to the frame and, when the second privacy screen element is in the closed position, is additionally magnetically held to the frame. Dividing the privacy screen element into three privacy screen panels means that the surface area of ​​the individual privacy screen panels, and in particular of the first privacy screen panel, can be smaller while maintaining the same total area. This, in turn, facilitates handling in the open position and also allows for a larger passage opening when the privacy screen panels are open.

[0022] In connection with this embodiment, it can additionally be provided that the third privacy screen panel can be carried along by the second privacy screen panel. This can be achieved, for example, by a spacer cable that connects the two privacy screen panels and is stretched between the privacy screen panels in a closed position, for example, while sagging in an open position.

[0023] Generally speaking, with regard to the magnetic mounting of a movable privacy screen, it can be provided that at least the second privacy screen and optionally the third privacy screen are connected to the frame via a retraction spring, so that when the mounting, for example the magnetic mounting or the mounting formed by the recess described above, is released in the closed position of the second privacy screen element, the second privacy screen is moved by the spring force of the retraction spring in the direction of an open position of the second privacy screen element. As a result, the second privacy screen can, for example, be brought into a position overlapping with the first privacy screen, for example, be moved into the slipstream of the first privacy screen, as soon as the magnetic mounting on the frame is released.In the case of a magnetic holder, the spring force of the return spring will be selected to be smaller than the magnetic force of the holder in order to prevent unintentional opening.

[0024] The privacy screens are preferably formed by tarpaulins, preferably made of plastic. The tarpaulins can be attached to the frame, for example, using press studs or with a preferably self-adhesive Velcro fastener. This allows the tarpaulins to be easily replaced. The tarpaulin of a privacy screen is preferably attached to at least two struts running vertically within the surface of the privacy screen and / or to the top and bottom edges of the privacy screen. The tarpaulin is preferably not attached to the frame at its outer lateral edges, so that in strong winds a portion of the tarpaulin can give way to the wind pressure and be bent backwards in the direction of the wind. In other words, this makes the tarpaulin partially permeable to wind. This means that the force of the wind can be directed onto the corresponding privacy screen orto the mobile privacy screen as a whole, preferably in particular to prevent the privacy screen from toppling over due to wind load. In order to prevent the lateral or vertical outer edges of the tarpaulin, which are not attached, from twisting or torsion, particularly in windy conditions, the outer edges can be stiffened, for example by means of a hem, an assembly strap or a cadre strap. Preferably, a tarpaulin of a privacy screen panel can give way to the wind over at least 50% of the surface of the tarpaulin. For this purpose, the at least two struts running vertically within the surface of the privacy screen panel can be arranged offset inwards from the outer edges by at least 25% of the (horizontal) width of the privacy screen panel.In order to further reduce the wind load on the privacy screen, a cut can be made in the tarpaulin, preferably a vertical cut in the middle of a privacy screen field, in particular in an otherwise non-yielding area of ​​the tarpaulin.

[0025] In this context, terms such as “top edge”, “bottom edge”, “lateral outer edges”, as well as “vertical” or “horizontal” refer to the privacy screen according to the invention in the erected position.

[0026] Alternatively or additionally, to reduce the wind load on a privacy screen element, a mechanism can be provided in which, similar to a swinging door, at least one privacy screen panel of a privacy screen element can be opened and closed. The privacy screen panel is then preferably connected to the frame on one side via at least one hinge. The described swinging door mechanism is, with respect to an individual privacy screen element, preferably used as an alternative to the sliding door-like opening and closing of a privacy screen panel described above. A privacy screen according to the invention can have privacy screen elements with a swinging door and / or privacy screen elements with a sliding door. Sliding doors can preferably be provided next to swinging doors in order to avoid collisions between adjacent swinging doors.

[0027] Alternatively, or additionally, the screen panels can be fitted with a mesh. This can further increase stability. The mesh can also be used to prevent people from crossing the screen.

[0028] The individual privacy screen elements are preferably separable from one another, allowing the overall length of the mobile privacy screen to be adjusted as needed. This allows even damaged privacy screen elements to be easily removed or replaced. Preferably, the mobile privacy screen can be connected to another mobile privacy screen according to the invention, with the connection preferably being made at each of the privacy screen elements of the respective mobile privacy screen.

[0029] Preferably, at least one privacy screen element has a ground cover which, when erected, can cover the gap between the lower edge of the frame of the privacy screen element and the ground.

[0030] The mobile privacy screen or an individual privacy screen element can be expanded if required with a lighting device, such as a light pole or a hazard warning light, a roof, a power connection, a camera or a heating device, for example an infrared panel or a radiant heater.

[0031] The mobile privacy screen can be equipped with a claw that can be connected to the base of a support of a privacy screen element. The claw is preferably a flat component on which a vehicle wheel can be placed, using the vehicle's weight to stabilize the screen and prevent it from tipping over.

[0032] The mobile privacy screen can be mounted on a means of transport, particularly a vehicle, such as an emergency vehicle. When mounted, the mobile privacy screen can be located both inside and outside the means of transport or vehicle.

[0033] Furthermore, the disclosure relates to a means of transport, in particular a vehicle, for use at an emergency site, wherein the means of transport is equipped with a privacy screen according to one of the variants and embodiments described above, wherein the privacy screen is pivotally mounted on or in the means of transport, wherein the privacy screen is connected to the means of transport via at least one detachable pivot bearing, preferably via two detachable pivot bearings, wherein the two pivot bearings are arranged in the region of opposite sides of the means of transport. The privacy screen can thus be pivoted selectively to one side or the other, depending on which pivot bearing is released. This has the advantage that the privacy screen can be erected starting from that side of the means of transport which lies outside the emergency site to be shielded.For example, vehicle doors can be opened into the area protected by the privacy screen, whereby the selectability of the pivot bearing makes it irrelevant on which side of the incident site the vehicle is parked. In general, the advantage of the two pivot bearings can also be achieved with a means of transport, regardless of whether the mobile privacy screen has a support, in particular a support of the type disclosed here. The disclosure therefore also encompasses such a general means of transport. In this context, a means of transport includes, among others, a vehicle, in particular a truck, which can be, for example, an emergency vehicle or a construction vehicle, a truck including a loaded container, a trailer or a roll container. The means of transport thus functions as a support system for the privacy screen.

[0034] The means of transport could be a trailer, for example, and the pivot bearings could be located near the front end of a loading area. This means that the privacy screen can be folded out or unfolded straight behind the trailer, i.e. without requiring space to the side of the trailer for folding or unfolding. A trailer is particularly suitable for situations where no existing vehicle is suitable for retrofitting the mobile privacy screen. The trailer also offers greater flexibility at the accident scene because it is small, lightweight, and maneuverable. The trailer can also be equipped with various additional functions such as a lighting set, generator, battery, oil absorbent, cameras, or display panels.

[0035] For example, the privacy screen can be located in a container, such as a large-capacity container, which can be loaded onto a vehicle. The container can be part of a swap body system, as is common for fire engines, for example. Within the large-capacity container, which is part of a swap body system, several interchangeable units are preferably provided which can be quickly replaced as needed or according to the type of use. The interchangeable units are preferably roll containers, each equipped with a set of equipment. The roll containers can preferably be pushed out of the large-capacity container via an open side wall of the large-capacity container. A ramp is preferably provided for pushing them out, preferably manually.The mobile privacy screen can be mounted on such a rolling container, allowing the container with the mobile privacy screen to be pushed out of the large-capacity container and the mobile privacy screen to be set up at the desired location from the container. Setting up is preferably carried out in a similar way to the method described for a general means of transport. The rolling container can also be equipped with crane eyes that allow the container to be lifted with a crane, allowing the container to be lifted from a vehicle using the crane.

[0036] In this context, extendable transport rails can be provided below the privacy screen in a transport position to extend the loading area rearward. This has the advantage that several privacy screen elements can be removed together to the rear of the trailer, facilitating subsequent lateral deployment (e.g., in a continuous line with the rear of the trailer).

[0037] The disclosure further relates to a method for shielding an emergency site with a mobile privacy screen according to one of the variants described above, comprising the steps of: moving the first privacy screen element and the second privacy screen element into a desired deployment position, extending the support along the support axis, and pivoting the base part about the support axis for lateral support. The order of extension and pivoting is irrelevant to the essence of the invention, and the invention relates to any possible sequence. In the context of the transport means described above, the method can further comprise the following steps: moving the transport means to the emergency site with the privacy screen in the transport position, releasing a pivot bearing, and erecting the privacy screen according to the steps described above.

[0038] In a preferred embodiment, the method comprises the following further steps: unlocking the support before extending the support, locking the extended support with the pivoted base part.

[0039] During the installation steps described above, the mobile privacy screen is preferably connected to the transport vehicle via a detachable pivot bearing. After completing the steps described above, the mobile privacy screen can be detached from the transport vehicle. This allows the transport vehicle to be moved away from the mobile privacy screen after installation, allowing the privacy screen to stand independently of the transport vehicle and thus be used as a freestanding device.

[0040] In a preferred embodiment, a subframe is connected to the vehicle via at least one pivot bearing, with the mobile privacy screen being connected to the subframe, preferably by at least one locking clamp or at least one spring lock. In this embodiment, the mobile privacy screen can be separated from the vehicle by releasing the connection to the subframe, while the subframe remains connected to the vehicle. The provision of a subframe enables even faster and easier installation of the privacy screen. Furthermore, the subframe can increase the stability of the mobile privacy screen, particularly during transport in the vehicle.

[0041] Depending on the connection of the subframe to the mobile privacy screen, a connection option with a locking clamp or spring lock can also be provided between individual privacy screen elements to enable easy extension or reduction of the overall length of the privacy screen as needed. A subframe can be mounted on one privacy screen and connected to another privacy screen. The subframe preferably allows at least one privacy screen panel of the adjacent (outermost) privacy screen elements of the two privacy screens to be opened.

[0042] Finally, the disclosure relates in particular to the use of a mobile privacy screen or a vehicle according to one of the variants and embodiments described above for shielding an emergency site. The invention is further explained below using exemplary embodiments, to which it is not intended to be limited, and with reference to the drawings. The drawings show in detail:

[0070] Figures 1-3 show a first embodiment of a mobile privacy screen 1 for mounting on a means of transport, specifically a vehicle in this example. The mobile privacy screen 1 comprises a first privacy screen element 2 and a second privacy screen element 3. For mounting on the vehicle, the first privacy screen element 2 has a fastening device 4. Both privacy screen elements 2, 3 are surface elements with a structurally predefined main extension plane. In the illustration shown here, the main extension planes are congruent. This means that the privacy screen elements 2, 3 are essentially flat, in this example rectangular, components. The second privacy screen element 3 is movably connected to the first privacy screen element 2.In this embodiment, the privacy screen elements 2, 3 are connected to each other via double joints 5, more precisely double hinge joints 6, so that the second privacy screen element 3 can be pivoted laterally in both directions from the parallel position shown here.

[0071] The mobile privacy screen 1 has two supports 7, 8. A support 8 assigned to the second privacy screen element 3 is shown in an operational position; a support 7 assigned to the first privacy screen element 2 is shown in a transport position. The supports 7, 8 are designed to provide lateral support for the mobile privacy screen 1 at approximately one-third the height of the second privacy screen element 3. The support 8 assigned to the second privacy screen element 3 (also called the second support) is extendable along a support axis 9 arranged parallel to the main extension plane of the second privacy screen element 3 and is extended accordingly in the illustrated operational position.

[0072] Both supports 7, 8 each have a base section 10 that can be pivoted about the support axis 9. The base section 10 is formed by an elongated structural element in the region of an end 11 of the support 8 remote from the frame. The base section 10 forms a right angle with the support axis 9 and extends symmetrically in two opposite directions starting from the support axis 9. It has the shape of a flattened crossbar, so that the support 8 as a whole has an inverted T-shape. In the illustrated deployment position of the second support 8, the base section 10 is pivoted by 90° compared to the transport position. In the transport position, as shown for the first support 7 assigned to the first privacy screen element 2, the base section 10 is arranged parallel below a lower cross strut 12 of a frame 13 of the privacy screen element 7 and is thus stowed away in a space-saving manner.

[0073] The two screen elements 2, 3 each have a first screen panel 14 and a second screen panel 15 as well as a frame 13. The first screen panel

[0074] 14 is essentially immovably connected (but elastically, see below) to the frame 13. The second privacy panel 15 is movable with the frame

[0075] 13. In the transport position shown on the first screen element 2, the second screen panel 15 is arranged superimposed on the first screen panel 14, so that between the frame 13 and the two screen panels 14,

[0076] 15 an opening 16 or passage in the privacy screen element 2 remains open. In the deployment position shown on the second privacy screen element 3, the second privacy screen panel 15 is displaced along rails 17 into this opening 16, so that the two privacy screen panels 14, 15 together essentially fill and cover the inner surface of the frame 13. The privacy screen panels 14, 15 in turn have an internal panel frame 18, which is covered on both sides with a tarpaulin 19. The rails 17 for the second privacy screen panel 15 are each formed by a metal rod on the top and bottom of the frame, along which the ends of the panel frame 18 of the second privacy screen panel 15 are slidably mounted. To protect the metal rods from bending or getting caught when climbing through the opening, they are protected with facings in the form of protective plates 20. The suspensions of the panel frames 18 of both the first privacy screen panel

[0077] 14 in frame 13 as well as the second privacy screen panel 15 on the metal rods can be implemented as elastic connections, e.g., via metal springs. This allows for cushioning against gusts of wind. Instead of the elastic connection, yielding in the event of gusts of wind can be achieved by a special fastening of the tarpaulins, in which, for example, the vertical longitudinal edges are not attached to the frame and can freely yield (as described in more detail above in the general description).

[0078] In this exemplary embodiment, a round guide tube 21 for the support 8, whose longitudinal axis also defines the support axis 9, is arranged centrally in the frame 13 between the privacy screen panels 14, 15. A handle 22 for unlocking, extending, and pivoting the support 7, 8 is thus accessible both in the transport position and in the deployment position. The arrangement in the center of the frame 13 enables a support width corresponding to the length of the lower edge of the frame 13 without the base section 10 protruding beyond the frame 13 in the transport position. This corresponds to lateral support of the mobile privacy screen 1 at half this support width.

[0079] Figures 4-6 show a second embodiment, wherein for the sake of simplicity only a second privacy screen element 23 is shown. This second privacy screen element 23 has three privacy panels 24-26. The second privacy screen element 23 has a first privacy panel 24, a second privacy panel 26 and a third privacy panel 25, as well as a frame 27, wherein the second privacy panel 26 and the third privacy panel 25 are movably connected to the frame 27. Both the second privacy panel 26 and the third privacy panel 25 are additionally held magnetically to the frame 27 when the second privacy screen element 23 is in the closed position. For this purpose, the metallic spacers 28, 29 are provided on the frame and the magnets 30, 31, 32 are provided on the privacy panels 25, 26.The second and third privacy screen panels 25, 26 are connected by a spacer cable 33, which allows the third privacy screen panel 25 to be carried along by the second privacy screen panel 26 during transfer from an open transport position to the illustrated closed deployment position. This allows both privacy screen panels 25, 26 to be closed with a single actuation. Furthermore, even in an open position (not shown) of the second privacy screen element 23, the second and third privacy screen panels 25, 26 are additionally magnetically held to the frame 27, more precisely to the metal spacers 34, 35.

[0080] The second and third privacy panels 25, 26 are each connected to the frame 27 via a retraction spring 36, 37. When the magnetic holder is released in the closed position of the second privacy element 23, the second privacy panel 26 or the third privacy panel 25 is moved toward the open position of the second privacy element 23 by the spring force of the retraction spring 36, 37.

[0081] Figures 7-11 show a third embodiment with a vehicle 38 as a means of transport for use at an emergency site. The vehicle 38 is an emergency vehicle which is equipped with a mobile privacy screen 39, e.g. according to the first or second embodiment. The privacy screen 39 is mounted on the rear 40 of the vehicle 38 and pivotally mounted. In detail, the privacy screen 39 is connected to the vehicle 38 via two detachable pivot bearings 41, 42. The two pivot bearings 41, 42 are arranged in the region of opposite sides of the vehicle 38. This means that a first pivot bearing 41 is essentially arranged on an extension of the right side wall of the vehicle 38 (seen in the direction of travel) and a second pivot bearing 42 is essentially arranged on an extension of the left side wall of the vehicle 38.Since both pivot bearings 41, 42 can be released individually, the mobile privacy screen 39 can be pivoted either to the right or the left, so that a tailgate of the emergency vehicle is arranged on the same side of the privacy screen 39 as an emergency scene, regardless of the direction and side from which the emergency vehicle approached the scene. For the sake of simplicity, both sides are shown in Fig. 11, although - as can be seen directly from Figures 9 and 10 - only one of the two privacy screens 39 shown here in the same drawing is actually present. This representation is merely intended to schematically illustrate that the mobile privacy screen 39 can be set up both straight and with several bends. By releasing both pivot bearings 41, 42, the mobile privacy screen 39 can also be completely removed from the emergency vehicle.If the weight of the privacy screen requires it, the vehicle 38 (e.g. a flatbed truck) can be equipped with a reinforced subframe and with transport rails 43, e.g. also for extending the subframe.

[0082] Figures 12-15 show a fourth embodiment in which the means of transport 44 is a trailer 45. The trailer 45 is equipped with a mobile screen 46 with thirteen screen elements 47. The trailer 45 has a closed, rigid box 48, on which the pivot bearings 49, 50 for the screen 46 are provided.

[0083] The pivot bearings 49, 50 for the mobile privacy screen 46 are arranged in the region of the front end 51 of a loading area 52 of the trailer 45. In a transport position, extendable transport rails 53 are provided below the privacy screen 46 to extend the loading area rearward. In the position shown in Fig. 14, a rear door 54 of the trailer 45 is open and the transport rails 53 are extended rearward together with a large part of the mobile privacy screen 46, so that the privacy screen 46 can be erected from this position both rearward and to either side. Fig. 15 shows an example of an erection straight rearward, whereby for reasons of space only the first six privacy screen elements 47 are shown in full and the seventh privacy screen element is cut off. From the third privacy screen element 47 onwards, the supports are extended and pivoted so that the lateral foot parts 10 are visible in the plan view.

[0084] The height adjustment mechanism 66 for the support 8 shown in Fig. 16a-i6e and Fig. 24-25 according to a further embodiment has a handle 22, a gear element 67 connected to the handle 22, and a rack 64. In a locked position of the height adjustment mechanism 66, as shown in Fig. 23, the handle 22 points upward, the gear element 67 is toothed with the rack 64, and the support 8 is fixed at a specific height. In an unlocked position, as shown in Fig. 24, the handle 22 points downward and all teeth of the gear element 67 are removed from the rack 64, so that the support 8 can be extended and retracted without hindrance. Fig. 16 shows the support 8 in the transport position, with the support 8 fully retracted and the height adjustment mechanism 66 locked. To extend the support 8, the handle 22 is first folded down, as shown in Fig. 16b.The support 8 is then rotated by 90° about the support axis so that the base part 10 is pivoted out, as shown in Fig. 16c. The support 8 is then extended to the desired height, as shown in Fig. 16d. The handle 22 is then folded upwards again to close the lock, as shown in Fig. 16e. In the retracted transport position, the support 8 is guided and locked by an L-shaped recess 68 in the guide tube 21 and a lower connecting pin 69 which connects the support 8 to the rack 64, whereby the recess 68 can prevent the support 8 from being undesiredly extended from the transport position. The guide tube 21 is fixedly connected to the frame 13. The handle 22 is connected via an axis 70 to a sleeve 71 which encloses a locking tube 72. The locking tube 72 serves to hold an upper part of the support 8 in the transport state and is rotatable together with the support 8 about the support axis.The locking tube 72 has an elongated recess 86 which serves to guide the support 8 when it is extended and retracted.

[0085] To retract the support 8, the steps described above and shown in Fig. i6a-i6e are performed in reverse order. To retract, first fold down the handle 22 to open the lock. Then, the support 8 is retracted and pivoted 90°. Finally, the lock is closed again by folding up the handle 22.

[0086] Fig. 21a shows a section through a privacy screen element with a frame 13 and a support 8 with a base section 10, with the support 8 and base section 10 in the transport position. The support has a toothed rack 64. The locking tube 72 is rotatable and is mounted on the frame 13 via a spring 65 and, in turn, serves as a spring-loaded bearing for the support 8. In the transport position, this bearing is under tension and can press the support 8 downward, thereby fixing the lower connecting pin 69 in the short leg of the L-shaped recess. As soon as the height adjustment mechanism (not shown) is unlocked, the spring 65 relaxes and allows the base part 10 to pivot by 90°, whereby the support 8 can be released from the transport position and extended along the recess 68 in the guide tube 21 and simultaneously along the recess 86 in the locking tube 72 until the support 8 reaches the ground.In this position, the height adjustment mechanism can be locked again, whereby the handle 22 with the gear element 67 is driven upwards along the rack 64 and lifts the sleeve 71 and the locking tube 72 against the spring force of the spring 65, whereby - depending on the ratio of the spring constant of the spring to the weight of the privacy screen element - the privacy screen element is also raised from a certain spring deflection. In Fig. 21b, a grooved tube 81 is visible, which is firmly connected to the frame 13. The grooved tube 81 is preferably screwed to the frame 13. The spring 65 is located in the grooved tube 81 and rests on a spring support 82. The grooved tube 81 is arranged in the locking tube 72, as can be seen in Fig. 21b. A U-shaped recess 83 in the grooved tube 81 is shown in Fig. 21c. On the opposite side of the grooved tube's outer surface, there is a second, similar recess. A split pin 84, visible in Fig.2id, is guided through bores in the locking tube 72, through the two U-shaped recesses in the grooved tube 81, and through a bore 85 in the spring support 82. The rotational movement of the locking tube 72 is guided by the split pin 84 and the U-shaped recesses 83 in the grooved tube 81. The legs of the two U-shaped recesses 83 are each offset by 90° on the outer surface of the grooved tube 81, so that the rotational movement is limited to 90°. The lower part of the locking tube 72 can accommodate the support 8, as shown in Fig. 21b, whereby the support 8 and the locking tube 72 can only be rotated together. In Fig. 2id, an elongated recess 86 of the locking tube 72 can be seen, which serves to enable the extension and retraction of the support 8, wherein the upper end of the rack 64 is connected to the support 8 via an upper connecting pin 87, as can be seen in Fig. 21a.The upper connecting pin 87 slides up and down in the elongated recess 86 as the support 8 is extended and retracted. When the support 8 rotates, the locking tube 72 is carried along by the upper connecting pin 87 and its stop in the elongated recess 86.

[0087] The frame shown in Fig. 22a has two stop elements 77, 78 which, in addition to the L-shaped recess 68, serve to prevent the support 8 from over-rotating when the support 8 is returned to the transport position (Fig. 16a). Two openings are provided in the base part 10 of the support 8, which can accommodate the two stop elements 77, 78, whereby only a first opening 79 is visible in Fig. 22b, which can accommodate the stop element 78. In Fig. 21a, a second opening 80 is visible, which can accommodate the stop element 77. By accommodating the stop elements 77, 78, the support 8 is secured against (vertical) movement along the support axis during transport, so that the preload of the spring 65 does not have to be fully absorbed by the lower connecting pin 69.

[0088] The privacy screen 1 shown in Fig. 17a and Fig. 17b has a fastening device 4 with an auxiliary frame 55. The auxiliary frame 55 is connected to a means of transport 44, preferably to a trailer 45, via at least one pivot bearing (not shown) and two hinges 73, 74. A side element 56 of the privacy screen 1 can be inserted into the auxiliary frame 55 and fastened to the auxiliary frame 55, preferably by at least one locking clamp or at least one spring lock 75, 76. In Fig. 17a, the side element 56 is inserted into the auxiliary frame 55 and fastened thereto. The privacy screen 1 can be separated from the means of transport 44 by opening the fastening and pulling it out of the auxiliary frame 55.

[0089] The privacy screen 1 shown in Fig. 18a, 18b, 18c and 18d has a first auxiliary support 57, which serves in particular to facilitate the extension of a support 8 of a privacy screen element 58 to be erected first. In Fig. 18a, the privacy screen 1 is in the transport position on a means of transport 44, for example a trailer 45 or a roll container 62. To erect the privacy screen 1, the privacy screen element 58 to be erected first is pivoted out slightly so that the first auxiliary support 57 can be extended. Then, in a second step, the first auxiliary support 57 is extended to the ground so that it bears at least part of the weight of the privacy screen element 58, as shown in Fig. 18b. As shown in Fig. 18c, the privacy screen element 58 is then pivoted out far enough to allow the support 8 to be extended and the base part 10 to be pivoted out.Since the privacy screen element 58 is already held at the desired height by the first auxiliary support 57, the support 8 of the privacy screen element 58 can now be extended without having to lift the privacy screen element 58. After the support 8 has been extended, the auxiliary support 57 can be retracted again, as shown in Fig. 18d. The further assembly is analogous to the embodiments described above.

[0090] The privacy screen 1 shown in Fig. 19 has, in addition to the first auxiliary support 57, a second auxiliary support 59, which can be used during assembly and disassembly of the privacy screen 1. During assembly, after the privacy screen 1 has been assembled and separated from the means of transport 44, in particular from the auxiliary frame 55, the second auxiliary support 59 can be extended so that the rearmost privacy screen element 61 is raised above the loading level of the means of transport 44 and the means of transport 44 can be easily moved away from under the privacy screen 1. During disassembly, after a rearmost support 60 has been retracted, the second auxiliary support 59 supports the weight of a rearmost privacy screen element 61 so that the latter can be transferred essentially horizontally into a means of transport 44, for example a roll container 62 or a trailer 45.

[0091] The claw 63 shown in Fig. 20 can be connected to a base section 10 of a support 8. A vehicle (not shown) can be parked on the claw 63 to stabilize the privacy screen 1 with the vehicle's weight and prevent the privacy screen 1 from falling over, even under strong transverse forces, for example, in strong winds or from fast-moving trucks. The connection between the claw 63 and the base section 10 is preferably frictionally connected by the weight of the vehicle parked on the claw 63.
