Description of the embodiments

An end plate 1.0 shown in FIG. 1 can consist of any suitable material (wood, plastic, metal, glass, stone, or the like). In addition, the end plate 1.0 can have special surfaces (patterns, advertising, game boards). Any shape that fits on a frame 2.0 is conceivable.

The end plate 1.0 can be stacked horizontally and vertically on other end plates 1.0 .

For non-slip support, the end plate 1.0 is achieved, for example, as shown in FIG. 2, through a bore 1.1 and / or a groove 1.2 . If the end plates are placed loosely or are locked by pins in through holes, they can be used on both sides.

The frame 2.0 consists of one, two, three, four or more legs, which can be connected with trusses and connect to the boom. The trusses can be arranged on the legs at any height. The frame 2.0 can be turned and tilted in any position. In Fig. 3 a trapezoidal frame is 2.0 with a front, long traverse 2.3 and a rear short Traverse 2.4 shown. The lateral cross members 2.5 are arranged tangentially on the legs (inside on the front legs 2.1 and outside on the rear legs 2.2 ). The cross members are connected to the legs in the upper area, the two side cross members 2.5 being arranged lower than the front, long cross member 2.3 between the front legs 2.1 , which must be "driven under" when being assembled by the frames 2.0 to be inserted. The rear, short crossbeam 2.4 is arbitrary in terms of height. Trapezoidal angle, leg profile and horizontal strength of the side cross members 2.5 form a mutually dependent geometry. Due to this geometry, one frame 2.0 fits into the other so that the front 2.1 stands on the front and the rear 2.2 stands on the rear legs, and the side crossbars 2.5 lie tightly against the side crossbars ( FIG. 1). The trapezoid is regular, ie there are only two interior angles. In special cases, the trapezoid can also be irregular, with an effect on the geometry. The height of the trusses does not belong to the mandatory geometry and can be freely selected.

In Fig. 4 it can be seen that the front, long cross member 2.3 between the front legs 2.1 can be dispensed with. This eliminates the need to "drive under" this long traverse 2.3 . Booms can be arranged on the legs. As an example, rear, end plate-side supports 2.9 are shown in this figure, which are attached to the rear legs 2.2 . If the rear, end plate-side support 2.9 is arranged in continuation of the rear, short cross member 2.4 and the end plate 1.0 is supported at the end points, the tilting moment of the end plate is reduced.

Fig. 5 shows that in order to reinforce the frame 2.0 between the rear legs 2.2 and between the front 2.1 and rear legs 2.2 , at any height, lateral trusses 2.6 and a short truss 2.7 near the ground are additionally attached. Depending on the system, there may only be the upper, long traverse 2.3 between the front legs 2.1 , since this is "driven under" by the frames 2.0 to be inserted when being assembled.

Alternatively, as shown in FIG. 6, the upper, long cross member 2.3 between the front legs 2.1 can be dispensed with.

The three-legged frame 3.1 and 3.2 shown in FIG. 7 obeys the same geometric rules and variants as the four-legged frames 2.0 . It is reduced to a rear leg 2.2 . The lateral crossbeams 2.5 and the near-ground rope crossbeams 2.6 are mutually arranged tangentially on the legs. In addition to the isosceles tripod frame 3.1, there is the isosceles tripod frame 3.2 .

The two-legged, trapezoidal frame 4.1 shown in FIG. 8 also obeys the same geometric rules and variants as the four-legged frames 2.0 . The traverses, however, become front, end plate-side 2.8 and rear, end plate-side arms 2.9 or front, bottom-side 2.10 and rear, bottom-side arms 2.11 . They attack each other tangentially.

Fig. 9 shows that the front and rear booms do not always have to be in pairs. They can also vary in length and be oriented in different directions.

The one-legged frame 5.0 shown in FIG. 10 obeys the same geometric rules as the four-legged frames. The crossbeams become front, end plate-side 2.8 and front, bottom-side brackets 2.10 .

The geometry of the trapezoidal shape is left by the two-legged frame shown in FIG. 11 with eight parallel arms 6.1 . As a result, it only obeys two dependencies: the leg profile and the truss or boom arrangement. The trapezoidal angle is eliminated, the brackets grip the legs at right angles. This means that the frames do not add up on a symmetrical axis, but diagonally. In Fig. 11 the legs 2.2 are in the middle, the outriggers (front, end plate-side outrigger 2.8 , rear, end plate-side outrigger 2.9 , front, bottom-side outrigger 2.10 rear, bottom-side outrigger 2.11 ) are each arranged in parallel on one leg, but are always on the same Side of the two legs.

In Fig. 11, a two-legged frame with four parallel arms 6.2 is shown. The arms (front, end plate-side arm 2.8 , front, bottom-side arm 2.10 ) point in the same direction. The legs are thus arranged on the edge and not in the axis.

As shown in FIG. 13, the frame can also be five-legged 7.0 and multi-legged (here: eight-legged 8.0). Here, for example, the fifth leg 2.15 is arranged between the rear legs 2 , 2 and the additional leg 2.16 mutually tangentially between the rear legs 2 , 2 and front legs 2.1 .

From Fig. 14 it is clear that the different frames can be extended by mutually attached cantilevers on the legs.

In Fig. 15 an end plate 1.0 is shown, which is placed directly on the various trusses and loose, easily detachable (latch, latch, snap) or firmly connected to the frame. The space for the front 2.1 or hind legs 2.2 is left out. The connection can be created, for example, by obstacles, non-slip covering, magnetic, by locking or screwing.

In Fig. 16 a closing plate 1.0 is shown that is placed directly on the legs and loose, easily be connected releasably or fixedly to the frame. A loose connection (pin / hole connection) is achieved, for example, by a shaped piece 2.20 , which is provided with a rounded support 2.21 and a cone 2.22 and is arranged at the upper end of one leg. At the corresponding point there is a bore 1.1 in the end plate 1.0 . Cone 2.22 and hole 1.1 work together so that the end plate is secured against horizontal displacement. The conical shape allows the plate to be inclined from the horizontal without the fitting 2.20 being subjected to additional stress.

Another connection is created in that a T-shaped support 2.25 is located at the upper end of the leg. The T-shaped supports 2.25 are used to transmit the load moment to the frame when the rectangular end plate 1.0 is loose. It consists of a tube 2.26 stuck vertically in one leg, which can also be made of solid material, and a corresponding support element 2.27 fastened at right angles above it.

The T-shaped supports 2.25 can be designed so that they can be pulled out upwards. For example, they can be arranged on the rear legs 2.2 and act together with the shaped piece 2.20 on the front legs 2.1 . The end plate 1.0 rotates around the fitting 2.20 and slides on the T-shaped support 2.25 .

In order to prevent accidental slipping, the plate can be held in a groove 1.2 of the end plate 1.0 by a square 2.28 in addition to the shaped piece 2.20 .

Fig. 17 shows a trapezoidal frame with fold closure plate 1.0. The folding mechanism consists of a hinge 1.4 , a hinge 2.30 (hinge) and an axis 1.5 located on the frame 2.0 . The end plate 1.0 lies on the supports 2.29 , on which it can also be snapped into place. In the folded-up position, the end plate is fixed by a holding mechanism (catch, spring, stop, holding rod; not shown).

Fig. 18 shows the space requirement of stacked furniture (24 tables, 24 chairs) in the set up and assembled state.

In order to be able to connect several tables together, connected them with coupling pieces. These clutches will for example from above before placing the plates attached.

Around the table for orthopedic needs in schools To grow with it, the legs are down or the Support can be extended upwards (also inclined). this function  can be combined with the desk position. A special Equipment allows pulling out to the height of the standing desk.

The frames described can be used in tight spaces when not in use Space is transported and put away. This attribute does not change by changing the dimensions as long the geometric system rules are observed.

That means the frames for tables of all sizes too for shelf-like frames up to scaffolding and spiral staircases as well as stages, platforms, exhibition racks for hanging of display boards and much more can be used. The frame carries vertical end plates, tarpaulins, surfaces, etc.
