Description

[0001] The invention relates to a stool comprising at least one balancing stone with a profiled underside. The invention further relates to a bench.

[0002] Balancing stones are known from the prior art and are marketed, for example, under the brand name Stapelstein®. These known balancing stones typically have a bowl-shaped structure, with an outwardly convex section that can be used for climbing or sitting when the underside, including the rim of the bowl, rests on a surface. The rim on the underside of these bowl-shaped balancing stones is usually profiled, often with a wavy surface.

[0003] When using these balancing stones, they are placed on the ground with their wavy edges facing upwards, so that the convex section points upwards and can be used for balancing exercises or as a seat. When used as a seat, this creates a stool. Depending on the person's height, several balancing stones can be stacked on top of each other to vary the height of the stool. However, a disadvantage is that when sitting on the top of a balancing stone, its position on the ground is fixed, as the increased friction between the lower edge of the stone and the ground, caused by the weight of the person sitting on it, prevents it from moving. In some situations, however, such movement is desirable. While the balancing stones can be moved more easily on the ground when unloaded, a certain amount of effort is still required.In this case too, easier repositioning would be desirable.

[0004] The object of the invention is therefore to further develop the balancing stones known per se in such a way that a seat stool that can be moved in an easy manner is provided.

[0005] This problem is solved by a stool with the features of claim 1. Accordingly, the problem is solved by the stool having a rolling platform with wheels and by providing recesses on an upper surface of the rolling platform, and by dimensioning and arranging these recesses such that they replicate a contour of the profiled underside of the balancing stone.

[0006] The recesses on the top of the rolling platform can be designed as openings or indentations, or as a combination of both, with their depths or profiles dimensioned to accommodate the profile of the underside of a balancing stone, thus creating a positive connection between the balancing stone and the rolling platform. The height of the stool can be varied by adjusting the number of balancing stones stacked on top of each other.

[0007] The balancing stones known from the prior art, in particular the Stapelsteine® (stacking stones), have a bowl-shaped design so that they can be stacked on top of each other. The lower edge of the Stapelsteine® is usually wavy. For use with these stacking stones, the roller boards are preferably designed so that both openings and depressions are incorporated into their upper surface. The shape of these openings and depressions is adapted to the wavy edge of the underside of the balancing stones, so that the raised sections of the wavy edge are accommodated in the openings of the roller board, and conversely, the depressions of the wavy edge are accommodated in the depressions on the upper surface of the roller board when the balancing stones are placed with their undersides facing down onto the upper surface of the roller board.The contours of the recesses on the upper surface of the rollerboard, in the form of openings and indentations, thus form a counterpart (a counter-contour) to the contours of the wavy edge on the underside of the balancing stone. In another embodiment, the recesses of the rollerboard are designed such that they form indentations, and these indentations accommodate the raised sections of the wavy edge of the balancing stone. The indentations of the wavy edge of the balancing stone rest on sections of the upper surface of the rollerboard located between the indentations of the rollerboard. In this embodiment as well, the indentations on the upper surface of the rollerboard form a counter-contour to the contours of the wavy edge on the underside of the balancing stone, so that a positive fit is formed between the raised sections of the wavy edge of the balancing stone and the indentations of the rollerboard.

[0008] The rolling platform of the stool can have a circumferential shape that is rotationally symmetrical about a central longitudinal axis. Such a shape allows for cost-effective production and space-saving storage of the rolling platforms.

[0009] In a particularly appealing design, the rotationally symmetrical circumferential shape of the rolling board can have shape elements evenly distributed over the circumferential shape, wherein the shape elements are bounded by an outer circle and an inner circle.

[0010] The outer contour of the skateboard is by no means limited to a rotationally symmetrical shape, but can be designed according to the desired aesthetic. For example, contours resembling the head or body of an animal, or even those of vehicles or toys, are conceivable. The skateboard can also extend far enough beyond the balance stone that the user can rest their feet on the resulting overhanging edge.

[0011] One design of the stool features a rolling base with mounting holes through which the casters can be attached using fasteners such as screws or bolts. The casters, which allow the stool to be rolled across the floor, are preferably mounted on its underside. The number of casters, and therefore the minimum number of mounting holes, should be chosen to ensure the stool's stability. Of course, the casters can also be attached to the rolling base in other ways, such as by plug-in, clamp, or adhesive connections. Furthermore, the casters can also be mounted on the outer edge of the rolling base.

[0012] The rolling base of the stool can be made of wood, plastic, a composite material, or a combination of materials. Wood is particularly well-suited as a renewable resource; moreover, it is easy to work with and offers versatile design possibilities.

[0013] Another embodiment of the invention relates to a bench comprising at least two of the described stools, wherein these stools are connected to each other at their upper ends by at least one connecting link. Naturally, more than two stools according to the invention can also be connected to each other in this manner.

[0014] The fundamental solution of the present invention therefore consists in the fact that at least one balancing stone with a profiled underside is positively connected to a rolling board, which has recesses in the form of openings and / or depressions, by placing it on the rolling board to form a seat stool. This positive connection ensures that the balancing stone and the rolling board do not slip relative to each other when the seat stool is moved.

[0015] Exemplary embodiments of the invention are explained below with reference to the drawings. The drawings show: Fig. 1 a stool in perspective view, Fig. 2. Placing a balancing stone on a rolling board, Fig. 3 a first embodiment of a skateboard in 3D view, Fig. 4 the first embodiment in top and sectional view, Fig. 5 a second embodiment of a skateboard in 3D view, Fig. 6 the second embodiment in top view and sectional view and Fig. 7 a bench in perspective view.

[0016] Fig. Figure 1 shows an embodiment of the stool 1 according to the invention. The stool 1 shown has two balance stones 2 and a rolling platform 3 with wheels 4. Recesses 5 (partially obscured) are arranged on the upper side of the rolling platform 3, into which a profile (not shown) on the underside of the lower balance stone 2 engages, creating a positive connection between the lower balance stone 2 and the rolling platform 3. The wheels 4 are mounted on the underside of the rolling platform 3 by means of corresponding fastening elements 7. The rolling platform 3, and thus also the stool 1, can be rolled across a floor (not shown) using these wheels 4.

[0017] In Fig. Figure 2 shows the placement of a balancing stone 2, here a stacking stone®, with its underside on the top side of a rolling board 3 according to the invention. The illustrated embodiment of the rolling board 3 has recesses 5a, 5b in the form of both openings 5a and depressions 5b. The illustration shows that the openings 5a on the top side of the rolling board 3 are dimensioned to accommodate the raised sections of the wavy edge of the balancing stone 2. It is also shown that the depressions 5b on the top side of the rolling board 3 are dimensioned to accommodate the depressions of the wavy edge of the balancing stone 2.When the underside of the balancing stone 2 rests on the top of the roller board 3, a positive fit is formed between the raised sections of the wavy edge of the balancing stone 2 and the recesses 5a of the roller board 3, as well as between the depressions 5b of the roller board 3 and the depressions of the wavy edge of the balancing stone 2. The balancing stone 2 is thus fixed to the roller board 3.

[0018] In Fig. Figure 3 shows a first embodiment of a roller board 3 in a 3D view. The roller board 3 has a circumferential shape rotationally symmetrical about a central longitudinal axis 8 and six recesses 5 evenly distributed around the circumference. The roller board 3 is also provided with a central bore 9. The central bore 9 serves, on the one hand, as a centering bore during the manufacture of the roller board 3 and, on the other hand, can facilitate the storage of the roller boards 3 by allowing them, for example, to be slid onto a rod (not shown) using the central bore 9.

[0019] Fig. Figure 4 shows the first embodiment of the skateboard 3. Fig. Figure 3 shows a top view and a sectional view. It can be seen that the shaped elements, evenly distributed around the circumference of the rollerboard 3, are alternately bounded by an outer circle 10 and an inner circle 11 in their outer diameter. The shaped elements bounded by the outer circle 10 are each provided with a mounting hole 6 for attaching rollers 4 (not shown). Also shown are six recesses 5 evenly distributed around the circumference of the rollerboard 3. The sectional view shows that the recesses 5 in the illustrated embodiment of the rollerboard 3 are depressions 5.In the case of a balancing stone 2 with a wavy edge on its underside, the recesses 5 for the support of the balancing stone 2 on the roller board 3 are dimensioned such that they accommodate the raised areas 2a of the wavy edge of the balancing stone 2 and the recesses 2b of the wavy edge of the balancing stone 2 rest on sections of the top of the roller board 3 arranged between the recesses 5, so that a positive fit is formed between the raised areas 2a of the wavy edge of the balancing stone 2 and the recesses 5b of the roller board 3.

[0020] In Fig. Figure 5 shows a second embodiment of a skateboard 3 in 3D view, and Fig. Figure 6 shows this second embodiment in a top view and a sectional view. Here too, the rollerboard 3 has a circumferential shape rotationally symmetrical about the central longitudinal axis 8 and six recesses 5 evenly distributed around the circumference, and is provided with a central bore 9. In this embodiment of the rollerboard 3 as well, the shape elements evenly distributed around the circumference are bounded by an outer circle 10 and an inner circle 11, in this case such that a flower-shaped outer contour is formed. The sectional view in Fig. Figure 6 shows that the recesses 5 in the illustrated embodiment of the roller board 3 are also depressions 5b. The mounting holes 6 for attaching the rollers 4 (not shown) are arranged inside the inner circle 11.

[0021] The outer contour of the rolling board 3 is by no means limited to a rotationally symmetrical shape, but can be designed according to the desired aesthetic. For example, contours corresponding to the head or body of an animal, or even contours of vehicles or toys, are conceivable.

[0022] Fig. Figure 7 shows an embodiment of a bench 12 according to the invention. The bench 12 shown has two of the described and in Fig. The two stools 1 shown in Figure 1 are connected at their upper ends by a connecting bridge 13. Each stool 1 has two balancing stones 2. The connecting bridge 13 rests on the upper surfaces of the respective upper balancing stones 2. The two stools 1 shown differ only in the circumferential shape of the roller boards 3 used; all other components, in particular the rollers 4, the fastening elements 7, and the recesses 5 (not shown), are identical. Naturally, more than two stools 1 according to the invention can also be connected in this way.

[0023] The invention is not limited to the embodiments shown. For example, the stool can be designed differently from the embodiment shown. Fig.1. The bench can also be formed with just one balancing stone resting on the rolling platform. Likewise, the bench can also have more than two balancing stones stacked on top of each other. Similarly, in further embodiments of the bench, it is provided that it is formed from benches according to the invention with one balancing stone or more than two balancing stones.
