Pig.9 a device for lifting the racks by means of a Threaded rod;

Pig.10a and b show another embodiment of the invention in two positions.

With reference to Pig. 1, 2 and 3, a platform 1 is shown, those made up of racks in the shape of boxes or boxes which are essentially semi-cylindrical in cross-section. 2 is formed, which are mounted on two axle carriers 3 (this is clearer from 'Pig.2 erischtlich). The axle supports divide the platform 1 into three parts, the middle of which is twice the length of the outer. Each of the frames 2 can accommodate four seats 5, two on middle part and one on each side of the axle beam 3 The platform 1 shown in Pig. 1 consists of seven frames 2, which, placed next to each other in a horizontal position, form a plane. The racks 2a, 2b and 2c do not carry any additional ones Element. On the other hand, the racks? D and 2g support seats 5, and the racks 2e and. 2f carry seats 5 and a table 6. Of course, this is only an example of how all frames 2 containing or supporting seats 5 can be arranged. The seats

-5-

609821/0344

are very simply attached to rotatable plates 4 that close the frames 2 and each one on their inner Carry surface-mounted rotating stand 5a, on which a shell-shaped seat 5b can be attached to the viewer carries «The seat 5b can rotate about the axis 5a, so that the viewer has a perfectly adequate horizontal angle take to the stage or follow an action that takes place in the hall. The one claimed by a seat 5 The range of rotation is indicated by hatching51.

Fig. 2 shows a section through the element shown in Fig.1 in Top view is shown. A certain number of components are shown again, in particular the frame 2. Within the frame 2b, an armchair or chair 5 is shown in a folded or folded position with dashed lines. The rotating stand 5a is always fixed to the plate 4; however, the seat pan 5b includes the stand 5a in position within the frame 2. In the example shown, a frame 2b contains four seats 5 o The rotating stands 5a are on the plates fixed so that with the seats 5 mounted the transverse movement is possible »The frame that supports the frames 2 is in turn formed by two axle beams 3, which are supported by four Cross members 17 are connected, which ensure the necessary transverse rigidity. The frames 2 are by means of axes mounted on support bearings 7 which are fastened to the axle carriers 3 are. The movement of the frames 2 <will> with respect to the axle carriers 3 <- below described.

In a front view, Pig.3 shows more clearly a module that supports the general Organization of a modular system allowed. The axle supports 2 are mounted in a support bracket 9, which is shown in FIG stands on the floor. On this connector or bracket 9, two legs of a Bussolenpaare are mounted, which with 10 and 11 are designated. The legs 10 and 11 rest with their other sides via rotatably mounted rollers 12 and 13 on the floor. As shown in Fig. 3, the support bracket 9 is actually supported on two Bussoles, which are aligned perpendicular to the axle carriers 3. The legs of these two Bussoles are two

connected by transverse axes 1B. On the side of the Banes 10 the transverse axis carries a lever 14 for the purpose of facilitating the lifting of the platform 1 at the beginning of its upward movement. On the side of the leg 11, the transverse axis 18 carries a block and tackle 15 »by means of which when the cable 16 is actuated Reduced angle between the Bussolenbeinen and the platform 1 can be raised. It is based on Pig.3 on it pointed out that the frames 2 have recesses 19 which allow their rotation about the axis B above the level of the axle carriers 3 allow.

Pig. 4 shows modules 20 and 21 arranged together, corresponding to the correspond to the module described with reference to Pig. 1 to 3 = Module 20 is in a relatively low position while module 21 is in a higher position so that the Frames 2 of the two modules form an essentially continuously rising ramp. The elements described so far have the same reference numbers. In Pig. 2 the module is in the retracted position or in one for transport suitable position. The module 20 according to Pig.4 is shown in the Raised position as follows: A rope 16 is on the one hand fixed to the movable rod of the Piaschenzuges 15 and on the other hand firmly attached to the lever 14. It is fixed at the reference point 25 of the lever 14. For the purpose of dividing up the force to be exerted by the rope runs over a series of pulley blocks 23; 24 and 22. At the start the pulley system pulls 15 the rope 16. The force is transmitted to the lever 14 via the rollers 22 to and the reference point 25. The lever then rotates around the axis IS and the roller 16 hits the crossbeam 17 and lifts the platform 1. The Piaschenzug 15 seizt his work and the carrying handle 9 lifts off the ground ο Palis the Piaschenzug continues its pull on the rope 16, in this way a configuration corresponding to that of module 21 in Pig.4 is achieved. The effect of the Piaschenzuges 15 makes it possible bring the center of gravity of the platform 1 to the desired height. The inclination of the platform 1 in one direction or the other can easily be set manually because yes the platform is balanced and moves it with weak action

can be.

To give an idea: a module of the type shown can accommodate 28 people. The stroke amplitude is 2.30 ι and the empty weight 1500 kg. The elements are for the

would take an additional weight of 500 kg per m.

When the desired inclination is reached, the axle supports connected to the bussole legs 10 and 11 by means of chains 27 and 28. The chains 27 and 23 are adjusted to the desired lengths. A third chain 29 connects the lower parts the legs 10 and 11 to prevent the platform 1 from collapsing in the event of a failure on the Piaschenzug 15. It stays alone setting up the racks so that the panels 4 are horizontal. The movement of the racks is controlled by a Mechanism accomplished, which is described below. The modules 20 and 21 are then attached to one another, for example by chains connected, the lobes 12 and 13 are blocked so. that the frame 2g of the module 20 is on the Level of the frame 2a of the module 21 is located

The side walls of the racks or boxes 2 are essentially semi-cylindrical and cooperate with the edges of adjacent ones Boxes so that the space taken up by the module is optically covered at all times. A section (not shown) makes it possible to attach railings or barriers to the edges of the racks. It goes without saying although the modules shown in Pig.4 are held together longitudinally by chains or anchors, that it it is possible to place such modules side by side in order to obtain a structure that is adapted to the problem to be solved. In Pig. 4 the lifting device consists of a Piachenzug. The roller 22 is a loose roller that allows constant To maintain tensile forces. The rope-roll system makes it possible Clue 25 to obtain a tensile force that is twice as great as that on the tension member 15 of the Piaschenzuges. Closing

borrowed, as already stated, the lever can be used to to block the slope for small angles.

The Fig.5a. and 5b show details of the construction of a frame 2 on the axle 3 and the crankshaft or _o-lever mechanism, which allows a according to the invention features the simultaneous control of the positions of all frames of a module. As already stated above, a frame 2 is supported by means of two support bearings 7 on two axle carriers 3. It can rotate about two axes 8. The frame 2 is on the other hand firmly attached to a narrow connecting rod or intermediate piece 30, which is hinged to a drive rod 31 _o The drive rod is normally close to and parallel to one of the axle carriers 3. It is in turn hinged to a connecting rod 32. The connecting rod 32 can the drive rod 31 transmit a longitudinal reciprocating motion which changes the inclination of the plane of the frames relative to the axle carrier plane. In particular, horizontal frames 2 can be achieved in this way if the axle supports 3 are tilted. The connecting rod 32 is in turn articulated to a spindle 33 which extends between the axle carriers 3 and is mounted in them. This spindle 33 can be rotated by the action of a threaded bolt 34 which cooperates with a stop or crank pin 35 fixedly attached to the spindle 33. The threaded bolt 34 is long enough so that its square-ended head lies in the upper surface of the frame or box 2. When the axle supports 3 are raised and locked in their position, the position of the frames 2 is adjusted by turning the threaded bolt 34. Of course, the movement of the frames 2 relative to the axle carriers 3 can be automated very easily by means of a winch or a shaded pole motor.

Fig.6 shows a second embodiment of the invention in which the shape of the boxes or racks 2 differs from the previous version and the positioning devices

are also designed differently. The module 36 is supported on the floor via an underframe 37 which mounted on rollers 33. A fixed winch 39 makes it possible to close the module 36 at a certain point fix. The axle supports 3 and their cross members (which cannot be seen in the Pig.) Are mounted on a lifting boom 40. This lifting boom 40 is articulated to the base 37 on its other side. At the center of the lifting boom 40 are push rods 41 hinged at the other end of the push rods 41 is the rod of a horizontal lifting device 42 is articulated. The pushing force of this lifting device 42 is through the Transfer rods 41 on the lifting beam 40 and a central pivot pin 43 on the axle support 3 is lifted. The platform 1 is inclined as described above by being placed in the inclined position with the aid of telescopic supports 44 and in this one kept wix'd. These supports 44 are on the one hand on the back and forth movable underframe 37 and on the other hand on the Platform 1 is articulated by means of front and rear fork joints 45. The frames 2 have in this embodiment, essentially a triangular cross-section. you will be supported by uprights 46, which are located at item 47 on the axle beams 3 and at item 43 on a drive rod 49 are mounted, which allows a longitudinal displacement to the upper surfaces 50 of the frames 2 in one way or the other Orientate direction. The shift of the drive rod 4Ü can be controlled automatically. As before, the frames 2 contain collapsed seats which are not shown. The inclination of the platform 1 can vary between 0 and 27. The minimum height of the modules is 35 -m, which means their transport very relieved. The maximum height of the central pivot pin 43 is 2.50 m and that of the last frame 4.20 m.

The Pigο7 and 8 show a third & execution form in which the folded module (Pig.8) is, for example, 31 cm high " These Piguren show elements that have already been explained, in particular the axle supports 3, a pair of Bussoles, of which only the Legs 10 and 11 are shown, and a fulcrum 52,

its function that of the support bracket 9 in Pig.2 or that of the The pivot pin 4-3 in Fig. 6 corresponds. The clue 52 carries a lifting device 53, which is telescopic, hydraulic, pneumatic or electrically designed or operated can. The legs 10 and 11 of the Bussolen are supported on a movable support. They are articulated with struts or 55 connected. When the platform 1 is raised by the lifting device 53 and inclined with respect to the horizontal its position is fixed by sleeve-shaped Supports 56 and 57 that allow the inclination to be adjusted and the module to be fixed to the ground. In this embodiment As before, the frames 2 form boxes or boxes for the arrangement of seats 5. The seats 5 are at this embodiment by telescopic, tubular Supports fixed at three or four points of a frame 2 by bolt connections, if one seat 5 per frame 2 is built in. Such a seat 5 is shown at 53. Railings or barriers are on the edges of the racks attached, additional sections are also attached to the edges to hold various accessories in place.

The lifting device for the frames, which will be described in detail with reference to FIGS. 9 and 10, consists essentially of threaded bolts on which there are two nuts with opposing threads (right and left threads), which are fixed to small rods 60_ below the racks are attached. The rotation of the threaded bolts, which is controlled for example by an electric motor, enables the frames 2 to be raised and lowered with respect to the axle supports. FIG. 8 shows the module in the collapsed position. The upper surfaces of the frames 2 form a floor 59. All parts of the module are in a horizontal position. If, for example, the frames 2e and 2f are raised, the other frames 2 remain in the retracted position, in contrast to the mode of operation of the other execution forms. The frames 2, which are raised by means of the small rods 60, are on the other hand mounted on the right and left of the axle support 3 on rotatable fork bearings 61 o

In the devices described above, the racks 2 are indirect mounted on the frame by two axle beams 3 connected by horizontal and / or diagonal cross members. the Racks generally have a rectangular shape, their cross-section is semi-cylindrical, triangular or rectangular. In a fourth embodiment, not shown, the frames are only supported by one axis, which is articulated one of the lifting elements described above can be raised. The frame 2 is in this single-axle support structure still overhanging mounted on the axle beam. The racks have a trapezoidal surface that is supported by the upper side of the module decreases towards the bottom ·> This enables the establishment of a round theater. The various modules are connected by adjacent elements that are attached to the Edges of the racks are attached. It is also possible in this way compilations of one-shaft and Make two-shaft modules.

9 and 10 show details of a lifting device for the racks with rotation of a threaded bolt which actuates two nuts with lugs with opposing threads. The lugs consequently approach each other, taking along small rods 60 which are articulated below the frame 2, and thus cause the frame 2 to lift . This figure shows the frame of the frame 2 and the rods 60, the upper ends of which are hinged to the axis of the frame 62 _o The fork bearings 61 are firmly attached to the cross members 63 of the frame 62 and rotate around a spindle which is attached to the axis is. This axis 64 forms an axis of rotation and storage for the frame 62. The threaded bolt 65 can be rotated either manually or by an electric motor. The nuts 16 and 67 with opposing threads together with the small push rods 60 form a type of lifting device that raises or lowers the frame 62.

Fig.10 shows an embodiment similar to that of Fig.7, but in which the upper surface of the racks 2 is always parallel
