Description

[0001] The present invention relates to a mobile stage.

[0002] Mobile stages are already a familiar concept and offer the advantage of flexible placement. They are commonly used at large festivals with limited durations. However, existing mobile stages have the disadvantage of requiring a relatively long time to prepare for transport, set up at the venue, and then dismantle for transport after the event. The larger the stage, the more effort is required for its setup. The time and expense associated with the lengthy setup process represent a significant cost factor.

[0003] The need for a stage exists not only at large festivals, but also at short-term, smaller events such as private parties, local music events, village festivals, or rallies. Due to the relatively small size of such events, there is a desire for a small stage that can be set up and taken down quickly at the venue, in order to minimize the time and costs associated with setting up and dismantling the stage.

[0004] Therefore, the object of the present invention is to provide a mobile stage that can be set up quickly for different events without time-consuming assembly. Furthermore, the object of the present invention is to provide a mobile stage that is easy to transport, particularly on a trailer.

[0005] The object of the present invention is solved by a mobile stage comprising a cuboid base body with a front and a back, wherein the base body has a stable open frame formed from longitudinal and transverse bars, and a first cuboid side body comprising a stable open first side frame formed from longitudinal and transverse bars, wherein the first side body is pivotably attached to the base body and wherein the pivot axis is aligned parallel to the longitudinal bars of the frame.

[0006] The longitudinal bars are usually vertically aligned, while the transverse bars are horizontally aligned.

[0007] Preferably, the first side frame of the first side body is pivotably attached to the base frame of the main body, with the pivot axis being aligned parallel to the longitudinal bars. In particular, a longitudinal bar of the first side frame and a longitudinal bar of the base frame are pivotably connected to each other. Rotating joint connections, such as hinges, can be provided to form this pivot connection.

[0008] The design of the main body as a stable, open frame constructed from longitudinal and transverse bars allows for transport of the main body as a prefabricated unit. This ensures safe transport of the mobile stage and eliminates the need for extensive assembly once the stage is on site. The inclusion of a first side section, also featuring a stable, open frame constructed from longitudinal and transverse bars, increases the usable area of ​​the mobile stage, thus enabling versatile and flexible use. Since the first side section is pivotally mounted to the main body, it can be positioned as needed, depending on the application.

[0009] Preferably, the mobile platform has a fully closed state and an open state, wherein in the open state the first side body is located outside the base body and in the fully closed state the first side body is located inside the base body. Providing a fully closed state in which the first side body is located inside the base body has the advantage that the mobile platform can be kept very compact for transport.

[0010] Preferably, the stable base has external dimensions that allow the mobile stage to be easily transported on the road using a trailer. Currently, the maximum permissible width is 2.50 m. Therefore, at least one side of the base should ideally not exceed 2.50 m. Since the first side panel is preferably located inside the base when closed, it does not contribute to the external dimensions when the platform is in transport condition.

[0011] In a preferred embodiment, the base body has two front longitudinal bars and two rear longitudinal bars, with the first side body pivotably attached to one of the two front longitudinal bars. This allows the first side body to be aligned flush with the front of the base body during operation, i.e., when the stage is in use. Alternatively, the first side body can also be pivotably attached to the rear longitudinal bar of the base body.

[0012] In order for the first side body to form a completely closed state to be fully accommodated in the base body, it is advantageous that the base body has a base body width and a base body depth, and that the first side body has a side body width and a side body depth, wherein the side body width is smaller than the base body width and the side body depth is smaller than the base body depth.

[0013] In a preferred embodiment, the first side body has walls. Depending on requirements, one or more of the following walls can be provided: a side wall, a rear wall, and a front wall. A top plate and a bottom plate can also be provided on the first side body. This makes it possible to completely or partially close off the first side body, in particular to enclose it.

[0014] The first side panel can therefore be used, for example, to house electronic components. For instance, speakers, lamps, or screens, or parts thereof, can be located inside the first side panel, facing forward when the mobile stage is open. The side and rear panels, as well as the top and bottom panels if applicable, ensure that the electronic components inside the first side panel are protected from external influences such as weather or theft. It goes without saying that the front panel can also be designed to protect the electronic components from the elements or theft.

[0015] It is understood that the first side body may additionally or alternatively also have a front wall; for example, the front wall can be used as an optical projection surface or as a carrier for advertising posters.

[0016] When the mobile stage is closed, the first side panel, with its corresponding side and rear walls, and optionally a front wall, can at least partially assume the function of the main body's side walls. However, if the first side panel has a smaller depth or width than the main body and thus does not completely form the side and / or rear wall of the main body, a pivotable plate, in particular a door, is pivotally attached to a longitudinal rod of the first side panel in a preferred embodiment. By means of the pivotable plate or door, one side of the main body can be completely covered. Providing a door offers the advantage of easily closing the access.

[0017] Additionally or alternatively, at least one pivotable plate is attached to an upper crossbar, a lower crossbar, or a longitudinal bar of the base body to at least partially close the base body. It is understood that several pivotable plates may be provided to completely close the base body.

[0018] In a preferred embodiment, the first side body is pivotably attached to the front longitudinal bar of the base frame. A pivotable plate, in particular a door, is pivotally attached to a longitudinal bar of the first side body. When the mobile stage is closed, this allows either the side of the base body or the front of the base body to be closed, depending on the longitudinal bar of the side body to which the door is pivotally attached.

[0019] Preferably, the base body has at least one wall. For example, a back wall and / or at least one side wall may be provided. In order to completely close the base body, pivotable plates may additionally or alternatively be provided on the longitudinal or transverse bars of the base body.

[0020] It goes without saying that the basic body may also include a top plate and / or a base element.

[0021] When the main body is fully enclosed, it forms a kind of completely sealed container that houses the first side section. In this case, it is advantageous that a panel pivots around a longitudinal axis and can be locked to serve as a door. This allows the mobile stage to remain at the venue after the event, protected from theft and the elements. Furthermore, the container-like design of the stage, when closed, provides excellent protection during transport on a trailer.

[0022] Preferably, the base element of the main body, which is designed, for example, as a base plate, has feet to raise the stage to a certain height. The feet can be swivelled for space-saving transport. The feet can be attached to the lower crossbars of the main frame.

[0023] For the transport of the mobile stage, it is advantageous that the base body has at least one attachment point for transport and / or fastening equipment.

[0024] The base may have a fastening option. This could be, for example, an opening in the base through which a fastening rope can be threaded.

[0025] Additionally or alternatively, the base plate can be fitted with openings for a forklift, similar to a transport pallet, to unload the stage from or load it onto a trailer. These openings can also be used to secure the stage on a trailer.

[0026] If suitable cranes are available, hooks or openings or the like may also be attached to the top of the base body to lift the mobile stage onto or off a trailer.

[0027] In a preferred embodiment, a second cuboid side body is provided, which has a stable, open second side frame formed from longitudinal and transverse bars and is pivotally attached to the base body, with the pivot axis aligned parallel to the longitudinal bars. This allows for flexible use of the mobile stage.

[0028] Similar to the first side frame, the second side frame can also be pivotally attached to the base frame of the main body, with the pivot axis aligned parallel to the longitudinal bars. In particular, a longitudinal bar of the second side frame and a longitudinal bar of the base frame are pivotally connected to each other. Rotating joint connections, such as hinges, can be used to create this pivot connection.

[0029] For easy transport of the mobile stage, both the first and second side panels are located inside the main body when closed. Particularly when the side panels contain speakers or lights, it is advantageous that the main body has a first front longitudinal bar and a second front longitudinal bar, with the first side panel pivotally attached to the first front longitudinal bar and the second side panel attached to the second front longitudinal bar, allowing the first and second side panels to pivot in opposite directions.

[0030] It goes without saying that the two side bodies can also be pivotally attached to the rear longitudinal bar.

[0031] The two side bodies can have different structures and functions, but it is advantageous if the first side body and the second side body are identical in construction.

[0032] In order to be able to place the two side bodies inside the base body in the closed state, it is advantageous that the base body has a width and a depth, and that the first side body and the second side body each have a width whose sum is less than the width of the base body, as well as a depth that is less than the depth of the base body.

[0033] Ideally, the sum of the two diagonal side bodies is smaller than the width of the base body, so that a counter-rotating swivel of the two side bodies is possible if they are each pivotably attached to the front or rear longitudinal rod.

[0034] Preferred embodiments are explained in more detail with reference to the accompanying drawings, which show: Fig. 1 the basic body of a mobile stage, Fig. 2 the main body and two side bodies of the mobile stage in the open state, Fig. 3 the base body and two side bodies in the closed state, Fig. 4 a partial view of the mobile stage with walls in open position, Fig. 5 the mobile stage in closed state, wherein the side bodies have side walls, Fig. 6 an alternative embodiment of the feet of the mobile stage, Fig. 7 a schematic representation of a mobile stage in closed position, Fig. 8 a schematic representation of a mobile stage in an open position, Fig. 9 an alternative schematic representation of a mobile platform in the open position and Fig. 10 a schematic representation of a lockable mobile stage.

[0035] Fig. Figure 1 shows a part of a mobile stage 10, namely the base body 12. The base body 12 serves as the main stage and is cuboid in shape with a front, a back, a right side, a left side, a bottom, and a top. The base body 12 has a stable, open frame formed from four longitudinal bars 14 and eight transverse bars 16. The four longitudinal bars 14 and eight transverse bars 16 form the edges of the cuboid base body 12 in a known manner. To stabilize the frame of the base body 12, intermediate bars 18 are provided in the area of ​​the back, the right side, the left side, the bottom, and the top of the base body. Depending on the stability requirements of the frame, these intermediate bars 18 are arranged parallel or perpendicular to the longitudinal bars 14 and / or parallel or perpendicular to the transverse bars 16.It is impractical to provide intermediate bars 18 at the front of the basic frame, as these could potentially reduce the stage opening. However, it is not impossible that intermediate bars 18 could also be attached to the front of the basic frame.

[0036] In embodiments not shown, more or fewer intermediate rods are provided.

[0037] The longitudinal bars 14 and transverse bars 16 are sturdy metal bars. The intermediate bars 18 are also made of metal.

[0038] On the underside of the base body 12, two parallel hollow strips 20, open at both ends, are provided. These strips are aligned in the plane of the underside of the base body or parallel to the plane of the underside of the base body, extend from the front to the rear of the base body 12, and are firmly connected to the crossbars 16 of the base frame that span the underside. The spacing of the hollow strips 20 is preferably suitable for receiving the forks of a forklift. Additionally or alternatively, securing cables for transport can be threaded through these hollow strips.

[0039] Furthermore, fixed support feet 22 are located on the underside of the base body 12 of the mobile stage, each with an opening 24. Like the hollow strips 20, this opening 24 serves as a fastening point for transport and / or securing devices. For example, this opening 24 can be used to thread fastening devices such as ropes through it to attach the mobile stage to a transport vehicle.

[0040] In Fig. Figure 2 shows a mobile stage 10 with a base body 12 and two side bodies 30a, 30b. Like the base body 12, each side body 30a, 30b also has a stable, open side frame formed from longitudinal bars 34a, 34b and transverse bars 36a, 36b. Like the base body 12, the two side bodies 30a, 30b are also cuboid in shape. The longitudinal bars 34a, 34b and transverse bars 36a, 36b of each side body 30a, 30b form the edges of the side frame. Furthermore, to stabilize each side frame, intermediate bars 38a, 38b may be provided in the area of ​​the rear, front, right side, left side, underside and top of the side frame, which are arranged parallel or perpendicular to the longitudinal bars 34a, 34b and / or parallel or perpendicular to the transverse bars 36a, 36b, depending on the requirements for the stability of the side frame.

[0041] The two side bodies 30a, 30b are pivotably attached, as first side body 30a and second side body 30b respectively, to a longitudinal rod, namely the front longitudinal rod of the base body 12. The pivot axis between the base body 12 and the side bodies 30a, 30b is aligned parallel to the corresponding longitudinal rods 14 of the base body 12. The pivot axis is designed such that the two side bodies 30a, 30b can rotate in opposite directions around the base body 12. The pivot connection can, for example, be a rotatable joint 39, in particular a hinge, which in this case is located outside the base body 12.

[0042] While Fig. 2 showing the base body 12 and the two side bodies 30a, 30b in the open state, is in Fig. 3 of the basic body 12 with the two side bodies 30a, 30b shown in the closed state.

[0043] As seen in the overall view of the Fig. 2 and Fig. As can be seen in Figure 3, the first side body 30a and the second side body 30b can be pivoted inwards, so that the first side body 30a and the second side body 30b are located inside the base body when closed.

[0044] As in the Fig. 4 and Fig. As indicated in Figure 5, the rear, right side (not shown), and left side (not shown) of the base body 12 have walls 40. A base element 44 with a base plate is provided on the underside, and the top is fitted with a cover plate 46, so that the base body 12 is enclosed except for the front.

[0045] The side bodies 30a and 30b, of which in Fig. 4 only the first side body 30a is recognizable, a right side, a left side, a back, which are provided with side walls 50. On the underside of each side body 30a, 30b a base element 54 with a base plate is provided and the top of each side body 30a, 30b is provided with a cover plate 56, so that each side body 30a, 30b is enclosed except for the front.

[0046] Inside the side panels 30a, 30b, electronic components for operating stage equipment such as loudspeakers, screens, and / or lighting systems may be located, although not shown. An outlet for an external power supply to power the electrical components within the side panel may be provided in a closed side wall. Depending on the application, the front panel may be fully or partially open to allow, for example, the mounting of screens, loudspeakers, or lighting systems.

[0047] Fig. Figure 5 shows the mobile stage 10 in a front view when the mobile stage 10 is in a closed state. As in Fig. As can be seen in Figure 5, the side walls 50 of each side body 30a, 30b, when closed, cover at least part of the front of the base body 12. The side walls 50 of each side body 30a, 30b thus serve, at least part of the way, as the front side wall of the base body 12. The front of each side body 30a, 30b faces the respective side wall of the base body, so that when closed, both side bodies 30a, 30b are completely enclosed. This has the advantage that sensitive components on the front of the side body 30a, 30b are protected from unauthorized access both during transport and overnight storage of the mobile stage 10 at the event venue.

[0048] In an alternative embodiment, as in Fig. As can be seen in figure 6, the feet 122 are designed to swivel.

[0049] In the Fig. 7 and Fig. Figure 8 shows the basic functionality of a mobile stage 110.

[0050] Fig. Figure 7 shows the mobile stage 110 in a closed position, specifically in the transport position, in which the side bodies 130a, 130b are located inside the base body 112. Fig. Figure 8 shows the mobile stage 110 in an open position.

[0051] The depth and width of the side bodies 130a, 130b are chosen such that both side bodies 130a, 130b can be pivoted into the base body 112. For the first side body 130a and the second side body 130b to be pivotable into the interior of the base body 112, the sum of the widths of the two side bodies 130a, 130b is each less than the width of the base body 112, and the depth of the two side bodies 130a, 130b is each less than the depth of the base body 112.

[0052] In embodiments in which at least the base body 112 has walls except on the front side, it is advantageous that the side bodies 130a, 130b are pivoted outwards from the base body 120 about a pivot axis 170.

[0053] In Fig. Figure 8 shows the transition from the closed position of the mobile stage 110 to the open position of the mobile stage 110 according to an embodiment in which the side bodies 130a, 130b are pivoted outwards from the base body 120 about a pivot axis 170. The side bodies 130a, 130b shown with dashed lines indicate intermediate positions.

[0054] At the in Fig. In the embodiment shown in Figure 8, in which the side bodies 130a, 130b are pivoted outwards from the base body 120 about a pivot axis 170, the angle by which the side bodies 130a, 130b must be pivoted to move from the open state to the closed state is approximately 270°. This requires approximately a three-quarter turn. To allow the two side bodies 130a, 130b to pivot simultaneously into the base body, each side body 130a, 130b has a diagonal length whose sum is preferably less than the width of the front face of the base frame.

[0055] Fig. Figure 9 shows another embodiment of a mobile stage 210, which differs from the one in Fig. The embodiment of a mobile stage 110 shown in Figure 8 differs in that the two side bodies 230a, 230b are pivoted inside the base body 220 about a pivot axis 270. In this case, the side walls of the base body 220 are omitted.

[0056] In this embodiment, where the two side bodies 230a, 230b are pivoted inside the base body 220 about a pivot axis 270, the angle by which the side bodies 230a, 230b must be pivoted to move from the open to the closed state is approximately 90°. This requires approximately a quarter turn. It is advantageous here that the sum of the widths of the two side bodies 230a, 230b is each less than the width of the base body 212, and that the diagonal length of each side body 230a, 230b is each less than the depth of the base body 212.

[0057] In a special embodiment of a mobile stage 310 as in Fig. As shown in Figure 10, the two side bodies 330a, 330b have a square cross-section. The base body 312 has both a rear wall 340 and side walls 342. The pivot axis 370 is designed such that the side bodies 330a, 330b are pivoted outwards from the base body 320 about a pivot axis 370. Each side body 330a, 330b has a right side, a left side, and a rear side, which are provided with side walls 350.

[0058] The side walls 350 of each side body 330a, 330b, when the mobile stage 310 is closed, cover at least part of the front of the base body 312. To cover the remaining open section on the front of the base body 312, a pivoting plate in the form of a door 380 is provided on the first side body 330a. The base body 312, which is enclosed except for the front, can be completely closed and even locked by means of the door 380.

[0059] In embodiments not shown, all or some of the side walls of the base body are omitted. To completely close the base body, at least vertically and circumferentially, pivotable plates (not shown) are provided, which are attached, for example, to a longitudinal bar of the side body. When the mobile stage is closed, this pivotable plate can be swung out and interact with the other side body, creating a closable wall. Furthermore, plates can be provided on the crossbar and / or longitudinal bar of the base body's frame, which are pivoted to close the base body.

[0060] The two side bodies can be identical in construction, but need not be. The invention also includes a stage (not shown) that has only one side body.

[0061] The size of the mobile stage 10, 110, 210, 310, in particular the base area of ​​the base body, is preferably designed so that the mobile stage 10, 110, 210, 310 can be transported on a trailer in road traffic.

[0062] For transport, the mobile stage (models 10, 110, 210, and 310) is converted into its transport configuration so that it can be lifted onto a trailer using appropriate fastening and transport equipment and secured there for transport. At the destination, the mobile stage (models 10, 110, 210, and 310) is unloaded from the trailer using appropriate transport equipment, moved to the desired location, and opened.

[0063] It goes without saying that the mobile stage does not necessarily have to be transported on a trailer, but can also be transported in any other known way.

[0064] The stage is essentially ready for use immediately after being moved into the open position. No significant assembly work is required on site.
