Description

GERMAN

In the theater, stage wagons essentially serve to create a playing area when several are put together to build. Depending on the type of stage, the stage wagons come with fixed rollers that are on rails run, or provided with swivel castors that run on the stage floor. Equipped with swivel castors Stage wagons have the advantage that they can be moved by hand into the stage area in any direction can be. For stage systems with a main stage and side stages arranged on one side the stage wagons must be able to be moved around the roundabout in order to set up and keep them ready of more than two sets. Here it is necessary to have the stage wagon in itself to guide intersecting grooves of the stage floor so that they do not run when moving. So far are Stage trolleys equipped with swivel castors are only used without guide means for guiding in the stage floor been.

It is known to stage wagons with fixed rollers by means of a sword, which is in the grooves of the The stage floor intervenes to lead. Here, however, only guidance in one direction is possible. Further has already been proposed to move a stage carriage in two mutually perpendicular directions to make it movable that of two separate sets of wheels for each direction of travel the one lifting and is designed to be lowerable and moves the other set of wheels in reverse when it is raised and lowered. One such an arrangement is cumbersome and expensive. In addition, such a stage wagon cannot be used in any Direction to be moved.

The purpose of the invention is to further develop a stage carriage provided with swivel castors in such a way that that it can also be moved out in two directions perpendicular to one another.

The invention consists in that the stage car provided in a known manner with swivel castors its underside, namely in its two main axes, which are perpendicular to one another, as a whole Guide elements that can be engaged and disengaged at the bottom or guide elements provided with parts that can be engaged and disengaged possesses, of which in each case the guide elements lying in one of the main axes with one of two vertically crossing, well-known grooves in the stage floor work together.

The guide elements are advantageously designed telescopically and the engagement and disengagement of the each intended to engage in one of the grooves in the manner of a bayonet catch by means of a part a handle which is guided in a U-shaped groove.

Intervene on the stage floor, it enables the stage carriage in two directions perpendicular to each other easy and safe to move. Due to the engagement and disengagement of the guide elements or certain The stage wagons can easily remove parts of them from the roundabout and pushed by hand in any direction, for example into an adjoining room, using the swivel castors will. In the adjoining room, which can serve as an alternative room, they can sit on a stage wagon Any decorations located there are dismantled and others are put back on it. The one with new ones Stage wagons with decorations can then be attached to the stage wagons in the stage rooms be driven up, whereby the same level of the work surface is available everywhere.

An exemplary embodiment of the invention is shown schematically in the drawing. It shows

1 shows the plan view of a stage carriage and the stage floor provided with crossed grooves, Fig. 2 shows the front view of the stage car and

Fig. 3 shows a detail.

The stage wagon 1 shown in Fig. 1 is provided in the vicinity of its four corners each having a caster 2, which is established by itself in the given direction of travel. In the central longitudinal axis 3 and in the central transverse axis 4, i.e. in the two main axes of the stage carriage, a guide element 5 is attached to its underside between two adjacent swivel castors 2 and cooperates with vertically intersecting grooves 6 in the stage floor 7 . Each guide element 5 can be engaged and disengaged or is provided with a part 9 which can be engaged and disengaged and which is vertically displaceable telescopically. Establishing

of the engaging and disengaging part 9 of the guide element 5 in the end positions can be achieved in the manner of a bayonet lock or by other known means. According to FIGS. 2 and 3, a pin 9, which represents the part 9 that can be engaged and disengaged, can be pushed up and off in a tube 8, which is open at the bottom and is attached to the underside of the stage carriage 1, of each guide element 5. Instead of a pin 9, a sword-shaped guide body, a roller or the like can also be provided. The downwardly pushed pin 9 engages in one of the grooves 6 in the stage floor 7 and thereby holds the moving stage wagon 1 in its path together with the further pin 9 located on the opposite side of the stage wagon 1, which also has to be pushed downward. The engagement and disengagement of the pin 9 is carried out by a handle 10 attached to it, which passes through the wall of the pipe 8 and is guided in a U-shaped slot 11 in the pipe wall. The exact shape and position of the slot 11 can be seen from the developed surface of the tube 8 shown in FIG. 3. The two free ends of the slot 11 are bent slightly downwards so that the handle 10 and with it the pin 9 are secured both in the uppermost and in the lowermost position. The corners 12 of the grooves 6 in the stage floor 7 that arise at the intersection of the grooves 6 are somewhat rounded for better guidance of the guide element 5 attached to the stage carriage 1. Should z. B. the stage carriage 1 previously moved in the longitudinal direction are moved in the transverse direction, then the guide elements 5 lying in the longitudinal direction or their parts 9 which can be engaged and disengaged are pulled up, d. H. disengaged, while the guide elements 5 lying in the transverse direction or their parts 9 which can be engaged and disengaged are pushed downward, d. H. be indented. If the stage carriage 1 is required at a point in the stage building where there are no grooves 6 in the floor, or if it should be able to be moved as desired on one of the stages by means of the swivel castors 2, then both the longitudinal and the transverse direction of the stage carriage 1 lying guide elements 5 or their disengageable and engaging parts 9 pulled up, d. H. be disengaged. In each of the main axes 3 and 4 of the stage wagon 1, more than two guide elements 5 can also be arranged. Patent claims: 1. Stage wagon for theaters, characterized in that the stage wagon (1 ) provided in a known manner with swivel rollers (2) on its underside, namely in its two mutually perpendicular main axes (3 and 4), guide elements (5 ) that can be engaged and disengaged ) or with insertable and releasable parts (9) has guide elements (5) , of which the guide elements (5) lying in one of the main axes (3 or 4 ) with one of two perpendicularly intersecting grooves known per se (6) work together in the stage floor (7) . 2. Stage wagon according to claim 1, characterized in that the guide elements (5) are telescopic and the engagement and disengagement of the respective part (9) intended to engage in one of the grooves (6 ) in the manner of a bayonet lock by means of a handle (10 ) , which is guided in a U- shaped groove (11).
