Abstract

The invention relates to a chair in the form of a wobble body, which represents a convex-wrapped Zweikreis- or Zweiellipsenroller. The seating is here preferably designed as Oloid, Paolo or Sphericon. The invention further relates to the use of the seat in medicine, physiotherapy, cosmetics and / or sports.

Description

The invention relates to a chair in the form of a wobble body, which represents a substantially convex-wrapped two-circle or Zweiellipsenroller.

The use of rocking seating furniture is basically known in practice.

There are known inflatable seat balls, the usual way of a gas or airtight material, such as plastic or rubber, and are compressed or filled with air under pressure. These seatballs are used as ergonomic and physiotherapeutic seating equipment, for example, for desk work. The necessary muscle tension of the sitter are considered to be advantageous from an orthopedic point of view.

A disadvantage of a seat ball is seen in the fact that the seat ball tends to roll due to its shape when not in use and especially in non-horizontal ground. This results from the simple experience that the seatballs get a slight twist when the user gets up (get off the ball) and roll away.

Even by slightly bumping the seat ball can roll unnoticed, so that you sit in the void.

When sitting on the seat ball occurs in the absence of a seat also instability of the ball position, since the ball is not always centrally applied by the person using.

In order to prevent rolling, several solutions are already known to provide the seat ball with holding racks, receiving trays or the like. This is from the publication DE 297 02 389 U1 a device with a ball seat known in which the ball seat is arranged in a round support frame. The seat ball carries on its upper dome a seat plate. By the holding frame of the ball is prevented from rolling away. However, the resting on the upper dome seat plate is easy to move and slippable when getting up. This can come with a quick succession of getting up and sitting to erratic movements and incorrect seats.

However, sitting balls are also considered to be unfavorable for prolonged use from a movement therapy point of view. The body must constantly balance the light movements of the ball and permanently change its position. In case of increased use (eg as office furniture), this can even cause permanent damage to muscles as it can overload the small muscles. As a result, the vertebral bodies are no longer held in the optimal position, and it comes to a permanent overload, which is reflected in the form of an unhealthy attitude. According to Professor Froböse of the Sport University of Cologne, the use of the ball as a pure seat opportunity such as in the office therefore should not exceed a duration of 30 minutes (Romans 2013 ).

Furthermore, in the strongly curved seat of a ball sitting behind the apex very quickly back and pelvis tilted backwards. Seat balls also stimulate hopping movements, which leads to a compression of the intervertebral discs and a corresponding load on the spine.

This is where the invention, which is based on the object to provide a multifunctional seating, which is improved in terms of the disadvantages described above.

This object is achieved according to the invention by the subject of the main claim. Specific embodiments of the invention are the subject of the additional dependent claims.

Summary of the invention

In a first aspect, the invention provides a multifunctional seating furniture, which consists of a molded body, which is designed as a wobble body.

The seating invention combines several key advantages over the known from the prior art rollable seating.

The seating is equipped as a swash body and thus allows physiotherapeutically advantageous manner an active balancing sitting.

Here, the seating has the decisive advantage that it can not roll away like a seat ball.

Through the continuous minimal compensatory movements, it can promote the sense of balance.

The seating invention thus combines a quiet multidirectional dynamic seating with a controlled asymmetric direction of movement.

The oloid-associated shape allows, in contrast to a ball sitting and sitting with variably bent legs and in particular at an angle of more than 90 °. As a result, you sit automatically upright and the pelvis is tilted forward, which promotes blood circulation to the internal organs and legs.

The swash body has four horizontally oriented or slightly concave side surfaces, one of which is always ready to move upwards. By designing these four surfaces with different surface structures, differently activating seat surfaces can be provided.

Another decisive advantage over a seat ball is to have in the property of the tumbling body according to the invention via two mutually perpendicular edges, both of which always limit the top of the seat. These edges can then, preferably designed thickened, serve to hold or support.

The wobble body allows by its shape a simple enclosure with a reference that designed as a detachable cover, easy cleaning of the chair.

Furthermore, the wobble according to the invention, in contrast to a ball stackable by simple side boundary.

Remarkably, numerous solutions are available for the specific embodiment of the invention. It can be made of a variety of materials, either as a hollow or solid molded body and the body can either be covered or have a braided or formed by rope / rods openwork outer shell.

Irrespective of its seat function, the swashbuckling body also represents an unconventional, aesthetically appealing spatial object.

In summary, the seating according to the invention provides an innovative and widely deployable seating concept that allows active and ergonomic seating as an aesthetic seating object.

Detailed description of the invention

In a preferred embodiment of the invention, the wobble body of the multifunctional seating furniture has a developable surface which can be transformed into the Euclidean plane without internal distortion of shape. This results in the formation of a tumbling, i. oscillatory rolling motion a bumpless rolling under with linear support surface, which rolls over the entire body surface by the rolling process, and thus results in a uniform stress on the body surface. A one-sided wear of the body is thus prevented.

In a further embodiment of the invention, the wobble body is formed in its shape by the convex hull of two vertically intersecting circles and / or ellipses in the multifunctional seating according to the invention, wherein the circles in the center and the ellipses preferably intersect in the main axis.

In an alternative embodiment, the ellipses intersect in the minor axis or the minor axis of the first ellipse intersects the major axis of the second ellipse.

The connection of two circles results in the formation of a two-circle scooter. The connection of two ellipses leads accordingly to a Zweiellipsenroller.

In one embodiment, both previously described scooters are characterized by having a constant center of gravity distance from the plane on which they rest.

This is for example given in the Sphericon or in a wobble body with a distance of A = √2.

In a preferred embodiment, both previously described rollers are characterized in that they have no constant center of gravity distance from the plane on which they rest. Such a scooter is more stable in its position and therefore has four rest positions corresponding to the four seating positions.

In a preferred embodiment, the two perpendicularly intersecting circles or ellipses are congruent, ie of the same size and the same shape. This creates a highly symmetric wobble body.

In the seating according to the invention, different configurations of the seat are possible based on the basic structure of the two-circle scooter or Zweiellipsenrollers by varying the circular distance or the ellipse distance.

In the case of two intersecting congruent circles, the following embodiments are particularly preferred for the seating furniture while varying their spacing A.

For the circle distance A = r, where r is the radius of the circle, the wobble body takes the form of an oloid. This form was discovered in 1929 by the sculptor and mechanical engineer Paul Schatz together with the everting cube.

For the circle distance A = 0, the tumbling body takes the form of a Sphericons, which was developed in 1980 by David Haran Hirsch.

For 0.25 r <A <0.75 r, where r is the radius of the circle, the wobble body takes the form of a Paolos. This is a new Taumelkörperform, which is more compact compared to the Oliod, insofar as it has a small width and depth at the same height and is therefore better suited as seating. The term "Paolo" is a neologism of "Paul" (treasure) and "Oloid". Since the Paolo has a square cross-section, it can be packaged in a cube-shaped box to save space. With the help of two parallel spacers several copies can be stacked on top of each other.

also von 0,486 r ein.In this case, in the case of the Paolo, the circular spacing A is preferably between 0.3r and 0.7r, more preferably between 0.4r and 0.6r, and takes in particular a value of $A=\sqrt{-2+\surd 5}\text{r}.$

So from 0.486 r.

For A> r, the tumbling body takes the form of an olongoid. Preferred here is a body with r <A <2r. Such a tumbling body has a shape extended from the oloid. The Olongoid is therefore particularly well suited as a bench for several people. The term "Olongoid" is a neologism of "Oloid" and "longus" (= long).

For a circle distance greater than 2 r are naturally no longer the two circles intersect, but the two circles are perpendicular to each other on an imaginary axis arranged so that this axis includes the center of the two circles.

In a further embodiment of the invention, the convex hull of the wobble body is formed by rectilinear ropes or rods connecting the support points of the two connected disc-shaped circles or ellipses to one another to obtain a connection port. With this configuration, the seating according to the invention can be reduced in weight, since it consists only of the two circular or elliptical interconnected segments and the rope or rod enclosure.

Here, the support points have a distance of between 0.5 and 5 cm, preferably between 1 and 4 cm and more preferably between 2 and 3 cm have.

In a preferred embodiment, the rectilinear ropes or rods are connected by transverse ropes or rods to a braid to produce a stable and aesthetically pleasing seat.

The inventive seating wobble body can also be configured either as a solid body or as a hollow body. In a solid body, a lighter material such as foamed plastic is recommended. The solid body can be constructed in a multi-layered manner, for example from a core with a cladding layer, wherein expediently the shaping solid core is surrounded by a softer, seat-friendly cladding layer.

1. a) Metall wie Edelstahl oder Aluminium;
2. b) Kunststoff, der bevorzugt ein aufgeschäumter Kunststoff ist, wie expandiertes Polypropylen (EPP), expandiertes Polystyrol (EPS), extrudiertes Polystyrol (XPS), Polyurethan-Schaum;
3. c) Holz wie Buchenholz, Fichtenholz, Esche, Bambus, Rattan oder Ahomholz
4. d) Holzwerkstoff wie Formsperrholz, Stauchholz (Bendwood) oder 3D-Funier; und
5. e) Verbundwerkstoff wie Faserverbundwerkstoff, hierbei insbesondere unter Verwendung von Naturfasern wie Hanf, Jute, Kenaf, Ramie oder Sisal oder Sandwichplatten mit Wabenkern und hierbei insbesondere Papierwaben mit tragender Deckhaut aus Aluminiumfolie;
6. f) Pappe wie Vollpappe oder Wellpappe.

In a preferred embodiment, the wobble includes in material selected from the group comprising:

1. a) metal such as stainless steel or aluminum;
2. b) plastic, which is preferably a foamed plastic, such as expanded polypropylene (EPP), expanded polystyrene (EPS), extruded polystyrene (XPS), polyurethane foam;
3. c) wood such as beech, spruce, ash, bamboo, rattan or ahomwood
4. d) wood material such as plywood, beech wood (Bendwood) or 3D-Funier; and
5. e) composite material such as fiber composite material, in particular using natural fibers such as hemp, jute, kenaf, ramie or sisal or sandwich panels with honeycomb core and in particular paper honeycomb with supporting cover skin of aluminum foil;
6. f) Cardboard such as solid board or corrugated board.

Particularly preferred in this case is the use of foamed plastics, since they represent a light and at the same time dimensionally stable material. In particular, these are EPP, EPS or XPS.

The mold for the foamed core can be produced with little effort from a flat sheet, since the entire surface of the Oloidkörpers is completely unwound in the plane. It is also possible to divide the body into 4 equal shell-shaped parts and to foam these smaller elements in a much smaller hollow shape in order to subsequently join them together to the overall shape of the wobble body, which is preferably a Paolo. For this purpose, it is advisable to additionally integrate a pin or other plug connection.

In a particularly preferred embodiment, the tumbling body consists of one of the materials listed above.

In a further embodiment, the wobble body is enveloped by a cover, which preferably consists of a textile material. Since the Taumelkörper belongs to the few bodies whose entire surface is kink-free and unwound in one piece, he is particularly well suited for a cover by a cover. As the inventors have found, the mutually perpendicular convex edges in the wobble rollers according to the invention ensure that such a cover sits firmly and undamaged on the molding. This is particularly important in a seating of great importance that the reference is exposed by the seat and engagement stress greater tensile forces.

The cover can consist of different materials. Examples may be mentioned here: leather, upholstered furniture, cork textile, textured textiles, fur, felt or artificial leather.

The cover may be waterproof, washable, anti-slip coated, or made of soft natural fiber, depending on the application, preferably the cover should not be too slippery, as otherwise they could slippage if moved too impulsively.

The wobble body according to the invention, which is preferably a Paolo, has a very easy-to-sew cover, in that it is cut out of only one coherent fabric part and sewn together at only 3 edges.

The multifunctional seating furniture according to the invention preferably has a handle device which can be used as an aid for a controlled sitting or for carrying or moving the seat.

The gripping device can be designed in any manner known to the person skilled in the art, for example as a gripping edge, handle, loop or handle. This gripping device can be mounted directly on the wobble body, solid body or covered body, in which case the gripping device is preferably arranged on the two edges formed by the outer segments of the ellipse or circles.

In a preferred embodiment, the cover comprises such a grip device. The reference-side gripping device is here preferably designed as a piping. This can be realized in a simple way with a textile covering material, in particular because here there is a seam course at the edges. Contrasting and thickened round piping can provide a secure hold when balancing, serve as a grip edge, better handling during transport and accentuate the two circular shaping edges. In addition, they protect the zipper or Velcro edge and visually hide it.

In an alternative embodiment, the molding forming the tumbling body has a gripping device. So it can be designed in one piece with this molding in the production of the molding.

In the case of the aforesaid gripping devices, whether they are attached to the body or to the side of the cover, it is preferred for these to be arranged on the two edges formed by the outer segments of the ellipses or circles. In a particularly preferred embodiment, these two edges of the wobble body are configured as a protruding gripping edge and in particular as a piping, so that the gripping edges come to lie on the top side and therefore easily accessible in every spatial position of the wobble body. Since the tumbling body according to the invention roll over the surface and not over the edges, the edge-side gripping device is particularly advantageous that on the one hand does not disturb the rolling process and on the other hand is not worn by a possible "rolling over".

In a preferred embodiment, in the multifunctional seating furniture, the cover is detachably attached to the tumbling body. So it can be removed for cleaning or replaced with a new cover. Conveniently, the cover is here provided at one or both edges of the wobble body with a closable opening, which extends particularly preferably over the length of the edge (s).

As a detachable and refastenable cover this is preferably equipped for closing the opening with a closure means. Since the edges also limit the unrolling surface laterally, they are not subjected to tension when unrolling but on the contrary to pressure, so that also zuzüpfindliche closure means can be used.

In a preferred manner, the closure means here is selected from the group comprising cords, hooks, buttons, snaps, adhesive strips, Velcro or zipper.

In a further embodiment, the multifunctional seating furniture is characterized in that the tumbling body or the cover enclosing it has a structured surface. As a result, the muscles and in particular the fascia can be stimulated in a controlled manner. In this case, the structured surface preferably comprises a structure which is selected from the group comprising knobs, rings, depressions, waves, grooves or points.

The structure may be present on the entire surface. Preferred here is an expression on only a part of the surface.

Notably, the wobble body has four different partial surfaces as seating surfaces and can be configured correspondingly with four different surface structures. These four faces are visible in the unwound surface as wing-like surfaces, as in 6 A represented and in the 6B and 6C derivable.

In a second aspect, the invention provides the multifunctional seating furniture according to the invention for use in medicine, physiotherapy, cosmetics and / or sports.

Sitting on a wobble body, which prefers a Paolo, works by balancing its body with gentle lateral rocking. Its metastable balance (the tumbling body is a rocking object) promotes balance through continuous minimal balancing movements. On the pelvis and back, especially the lumbar area, it has a wonderfully relaxing effect, because it causes the lliosacral joint (joint between the pelvis and spine), which is very often strained during back pain, to be asymmetrically stretched (laterofixion of the pelvis) and thus loosened. The legs always actively support the balance, one leg is support leg and the other leg. On the wobble body, which is preferably a Paolo, you sit automatically upright, the pelvis tilted forward (greater than 90 °). This promotes blood circulation to the internal organs and legs. For smaller people and children, a smaller version can be used.

The asymmetric seating position can be easily changed by turning 90 degrees or rolling over a quarter of the area to alternate the support and the can leg and to stretch the pelvis along the other diagonal.

The seat of the swash body always points upwards and does not roll away, is more stable than a ball. You can hold on to the side piping edges or rest on the side surfaces with your hands. This asymmetric 3-dimensional movement pattern can not be stored as a schema in the brain as quickly. Even after many repetitions, the diagonal "swings" on the body is always surprising and therefore long-lasting motivating. The organ of balance is repeatedly activated and the receptors in the joints are also continuously mobilized, so that the so-called "proprioceptive training" strengthens the deep muscles in the joints and helps to stabilize them and relieve joint pain. The body can relax and the head becomes free (Braintrain). Best condition, therefore, to focus on new things.

This is the first seat object that allows this 3-dimensional controlled asymmetric diagonal movement. In everyday life, on the other hand, it is very common and important, e.g. when walking, running, climbing stairs or cycling. This complex movement can hardly be verbalized and executed at home as a relaxing seat movement without the aid of an olio-like seat object.

The seating according to the invention, preferably in the form of a Paolo, creates an ergonomic dynamic sitting experience and calls for playing and experimenting with new sitting positions: e.g. in the yoga seat, in the rider's seat swiveling back and forth, cross-legged.

With a partner, you can even sit and ride back to back with two of you! You can also kneel or stand on it and lie on your stomach or back. In particular, lying on the back extends the neck and pelvis in the opposite direction to the usual posture and strengthens, by continuously pushing back and forth with the legs, neck muscles and pelvic extensors, which are shortened in most "sitting people".

The seat, which is preferably a Paolo, is an aesthetic seating object for active ergonomic sitting, an eye-catcher with a strong appeal character for office and home, which motivates one to playfully discover a new dynamic sitting experience on PAOLO: lying, kneeling in the yoga seat or bobbing for two , etc.

Especially in the lumbar / pelvic region, the relaxing effect of gentle "diagonal swings" on PAOLO is perceived as very beneficial. It relaxes, invigorates and frees the mind and body at the same time and has a particularly activating effect on team discussions.

Due to its exceptional shape and its experimental, unconventional seating experience, PAOLO is the ideal seating for communicative occasions, collaborative team phases and creative design thinking processes: brainstorming, warming-up, think tank. The mind is free for new creative thinking strategies and problem solutions.

If you use textiles from a washable anti-slip fabric, PAOLO can be used in fitness-wellness and physio-areas.

Because it has a relaxing effect on both body and soul, PAOLO could also be used in therapeutic and rehabilitation centers.

With a padding of polystyrene beads and EPP core, PAOLO is even suitable for outdoor use. A smaller version is also suitable for children as a free movement play and sitting object and can be used in kindergarten and school.

In a third aspect of the invention, a massaging device is provided in the form of the wobble body according to the invention, wherein it has a maximum length, defined as the distance of the outer edge of the circle segments, of 30 cm and is preferably a Paolo. In this embodiment, the tumbling body can be used as a massaging device for the whole body, and in particular for the hand and foot serve. There are different material variants possible: Firstly, with pimples or rubber adhesive four different massage-effective structures can be applied to a textile shell, which is filled with different solid foam, or as full foam EPP with four different incorporated nub variants.

In a fourth aspect of the invention, a hand flatter is provided in the form of a Paolo. This preferably has a maximum length (= 2r) of 8 cm. Such a flatterer suitably consists of haptically appealing textile materials, such as velvet, leather, felt, silk, linen, fur or other structures coated small oloidähnliche foam body.

In a fifth aspect of the invention, a throwing object is provided for playing in the form of a paolo. This is preferably the size of a rugby ball.

In a sixth aspect of the invention, soft play and crush ball play is provided in the form of a paolo, which is preferably rubber and has a size of 12-20 cm. Dogs can grasp this particularly well on the edges with the teeth, the edges are always up.

In a seventh aspect of the invention, there is provided a pen holder for writing in the form of a paolo having, as an ergonomic handle, a diagonally mounted hole of different diameters for passing pins of all kinds. This is preferably made of an elastomer or EVA foam

definitions

A "wobble body" is defined according to the invention as a body having a straight contact line when rolling on a flat support surface, the angle of this contact line to the direction of travel oscillatingly changing to result in a "wobbling" rolling motion.

A "developable surface" in geometry refers to a two-dimensional surface that can be transformed into the Euclidean plane without internal deformation. It may finally be made many cuts, but the individual parts must then be placed on a plane without further upsetting or squeezing. According to the mathematical definition, an area, or more precisely, a two-dimensional differentiable manifold, is said to be unwound if its Gaussian curvature is zero at any point on the surface, which happens exactly when either (or both) major curvatures is zero , Often, the Oloid, Paolo and Sphericon are one of the very few known bodies whose entire surface is kink-free and unwindable in one piece.

The "convex hull" of a subset is the smallest convex set that contains the initial set. In mathematics, a geometric figure is called convex if, for every two arbitrary points belonging to the set, their connecting distance lies entirely in the set. This guarantees that the amount at any point has a (concave) indentation.

By a "substantially convex hull" is meant a hull that is minor, i. as a seat support suitable concave indentations.

The "center" of a circle is defined as the secant that passes through the center of the circle.

The "major axis" of an ellipse is the degree that passes through both foci of the ellipse.

A "connection port" is defined as a developable interface.

A "rope" in the context of the invention is an elongated, pliable, elastic element. This includes cords, ropes, cords, cords, twine but also ribbons.

A "rod" in the context of the invention is an elongated rod-shaped, rigid object. This includes rods, rods, tubes and strips.

The invention is illustrated in the drawings and described below.
