Description

Technical area

The present invention relates to a folding stool for exercising rocking movements, comprising at least two side parts, at least one seat part and at least one covering part, in which the side parts are aligned in an operating state at an angle of greater than 90 ° to the seat part. The side parts are connected to one another on a half facing away from the seat part by at least one tensile forces receiving connecting element, such as a belt.

State of the art

In a society in which many people spend their working day in a sitting position, increased health problems occur due to the body posture when sitting. Studies have shown that sitting does not provide optimal static posture, but that movement while sitting is essential for preventing health problems. Movement while sitting, also known as dynamic sitting, is possible on rocking chairs or rocking stools, for example. The curved support surfaces of such seating a rocking motion is stimulated, which forces the person sitting on the chair, so to speak, to move. Through this movement, the muscles are relaxed and trained the sense of balance. From the prior art, various types of seating are known, which allow a rocking motion. These include the classic rocking chair with backrest and the well-known rocking horse for children. Furthermore, modern molded seating are known, which also allow rocking movements while sitting. A disadvantage of these known seating is that they are relatively heavy. In addition, these furniture are usually designed expansively. As a result, they are unwieldy and in the event of non-use impractical to stow. In this regard, there are already seating, in which the aspect of practical and space-saving storage has been implemented. Among other things, from this aspect, for example, from the French patent application FR3050369A1 a stool known, which is constructed of a flexible material and is held together with a lanyard. After removal of the strap, this stool can be stored to save space. The seat and the downwardly oriented area of this stool are made of the same material. A disadvantage of this solution is the low stability, whereby the disclosed stool is not suitable for the exercise of rocking movements. It is therefore the object of the invention to propose a chair with a low weight, on which swinging movements can be performed and which can be stowed to save space.

Summary of the invention

• - zumindest zwei Seitenteilen bestehend aus einem biegeelastischen Material, wobei die Seitenteile eine bogenförmige Bodenkante und eine Oberkante aufweisen,
• - zumindest einem Sitzteil bestehend aus einem biegeelastischen Material, welches zwei Außenkanten mit einer zur Oberkante komplementären Form aufweist,
• - zumindest einem Bespannungsteil, welches aus einem flexiblen Material besteht und welches zwei Verbindungsränder und ein Mittelstück aufweist.

The above object of the invention is achieved by a folding stool for exercising rocking movements, with

• at least two side parts consisting of a flexurally elastic material, wherein the side parts have an arcuate bottom edge and a top edge,
• at least one seat part consisting of a flexurally elastic material which has two outer edges with a shape complementary to the upper edge,
• - At least one covering part, which consists of a flexible material and which has two connecting edges and a center piece.

In this case, each connecting edge of the covering part is each connected to an upper edge of a side part and the center piece of the covering part with the seat part, wherein an outer edge of the seat part is adjacent to an upper edge connected to the covering part. The side parts are aligned in a state of use at an angle of greater than 90 ° to the seat part, and the side parts are on a half facing away from the seat part by at least one tensile forces receiving connector, such as a belt, connected to each other, through this connection of the two Side parts with the belt, the side parts and the seat are under bending stress.

A folding stool according to the invention consistently uses the principles of lightweight construction. For this purpose, the Falthocker comprises at least two side parts over which the contact is made to the ground. In order to enable rocking movements, the ground edges oriented towards the ground have a curved shape. The Falthocker rolls off the rocking movements on these floor edges. It is conceivable that the bottom edges oriented towards the ground further each have a short flattened portion at a vertex of the curved shape, so that the Faltsocker can rest safely in the unused condition on the flattened sections, without a abutment of the Falthockers this already in rocking motion bring to. This allows a stable resting state of the Falthockers as a design option.

Opposite the bottom edge, an upper edge of the side part is arranged. The ends of bottom edge and top edge are through Linked side edges. The side panels form the static supporting part of the folding stool. The side parts are made of a flexible material. This material is elastically deformable and takes after a load back to its original shape. Suitable materials for the side panels are for example wood or plastics. An inventive folding stool is used in a state of use as a chair. This means that the folding stool is completely assembled in the state of use. However, for space-saving storage of the folding stool this can also be converted into a storage state in which a part of the components is removed and the orientation of the individual components to each other partially deviates from the orientation in the use state.

A folding stool according to the invention furthermore comprises at least one seat part, which in the use state is arranged between the side parts and provides the seat surface. The seat part is conveniently made of flexible material and can be performed, for example, lenticular. The seat part is bounded by two outer edges which have a shape complementary to the upper edge of the side parts. Due to this complementary design, side parts and seat part can very well transmit forces to each other. The complementary shape is a large-scale investment between these parts. The side parts and the seat part are connected to each other via the covering part. For this purpose, the covering part has a center piece, which is arranged in the assembled state of the folding stool on the seat part. Adjacent to the middle piece, a connecting edge is arranged on each side, which is intended to be connected to the side part. The covering part is made of flexible material. Such a flexible material is not rigid but can be easily folded and elastically deformed. Preferably, however, this flexible material is designed tensile strength and can not or only slightly by introduced tensile forces which. A suitable material for the covering part is leather.

The covering part forms the connecting element for side parts and seat part. First, the center piece of the covering part is connected to the seat part. Such a connection may conveniently be made by a seam. However, other types of connections, such as an adhesive bond with belonging to the invention. Furthermore, the connection edges are connected to the upper edges of the side parts. Characterized in that the covering part is made flexible, the position, in particular the angle of both side parts to the seat part can be changed within certain limits. In the condition of use consists in the area where seat part and side parts to each other borders an angle greater than 90 °. The centrally disposed between the two side parts seat part is aligned in the use state substantially horizontally, the two side parts extend from the seat part down and out. The bottom edges of the side panels are in the state of use further apart than the top edges. In the area where the seat part and side parts adjoin one another, these parts are connected to one another by the covering part. On the opposite side, in the upper edge facing away from half of the side parts a tensile forces receiving connecting element is provided, which connects the two side parts together. The tension-receiving connection element is preferably a flexible connecting element, for example in the form of a belt. This connecting element ensures the stability of the Falthockers by preventing sliding of the bottom edges of the side parts. According to the invention, however, the connecting element additionally ensures that a bending stress is created in the seat part and the side parts. This bending stress is essential for the function of the Falthockers invention.

According to the invention, side parts, seat part and covering part are made of very light and thin materials. To obtain the required strength, the folding stool is biased by the belt. For this purpose, the side parts and the seat part are elastically deformed when pulling the belt and thereby causing contraction of the side panels. By this deformation creates a bending stress, which in turn counteracts the tensile force of the belt. In the state of use, there is a balance of forces between the tension in the belt and the bending stress in the flexurally elastic parts. By this bias of the Falthockers side parts and seat part are firmly pulled together, whereby a good power transmission is ensured by the seat part to the side panels. In addition, the seat part and the side parts are given a curved shape that is statically more resistant than a flat shape. Due to the very thin dimensioned components, a folding stool according to the invention has a very low weight and is therefore easy to handle alone. At the same time, the folding stool is sturdy enough to carry a heavy adult safely.

A folding stool according to the invention has a further advantage: after removal or detachment of the belt, side parts and seat part are no longer deformed, and then there is no longer any bending stress in these parts. The state after removing or loosening the belt is the storage condition in which the parts resume their flat or flat original shape. After removal of the belt, the side parts can be folded next to the seat part, the inventive Falstocker is then even and very thin and can be stored very space-saving. This storage condition additionally improves the handling of the Falthockers, especially if this is to be stowed to save space in the event of non-use. A further advantage of a folding stool according to the invention is that it can be transferred in simple steps from the use state to the storage state and vice versa. No tools are required for this transfer.

In a favorable embodiment, it is provided that the seat part is designed lens-shaped, the outer edges each have a convex curvature and the upper edges each have a concave curvature. In this embodiment, the contiguous edges of seat part and side parts are curved. This curved design creates a folding stool in the condition of use, which is shaped in the upper area similar to a saddle. Thus, sitting on the folding stool is very comfortable and swinging movements can be carried out easily. Of course, outer edges and upper edges may also have other geometry and contain, for example, rectilinear areas.

In one possible embodiment, a storage state of the folding stool is provided, in which the belt is removed from at least one side part and the side parts and the seat part are flat in the storage state. When in use, both side parts are connected to each other by the belt and braced. To transfer to the storage condition, the tension caused by the belt must be released. For this it is sufficient if the belt is at least removed from a side part. Of course, the belt can be completely disassembled in the storage condition. Particularly favorable for a space-saving storage is when seat and side panels are flat or flat in the storage condition. Such planar materials are available easily and in a wide range, which enables a cost-effective production of the Falthockers.

In a further embodiment, it is provided that in the storage state between the outer edge of the seat part and the upper edge of the side part there is a gap which is covered by the connecting covering part. In the storage condition, seat part and side parts are flat. The three parts are aligned with each other by a connection with the covering part. In this case, a gap is provided between an outer edge of the seat part and an upper edge of a side part. Since outer edge and upper edge are complementary in shape, this gap has a substantially constant width along the edges. Conveniently, the width of the gap is in the order of magnitude of the material thickness of side parts and seat part. The gap is present between the seat part and side parts, but is spanned by the covering part. The covering part forms, as it were, a bending joint between the seat part and the side parts in the gap. As a result, the parts which are just adjacent to one another in the stored state can be folded together, so that finally the state of use results. When folding the side parts towards the seat part of the gap is increasingly smaller.

It is expediently provided that, in the state of use, the gap present in the state of storage is ideally closed and the outer edge and upper edge touch each other. In the state of use, upper edges and outer edges touch each other. Thus, a positive connection between the seat part and side parts is then given, which allows a very good power transmission between the parts. In the state of use, the seat part and the side parts are held together by the covering part, which is in the use state in the boundary region between the seat part and side parts under tension. This gives a good flow of force between the parts.

In a further preferred embodiment, it is provided that the side part has a plurality of fastening openings, is guided in the state of use, the tensile forces receiving connecting element in the form of the belt and the mounting holes within the upper edge facing away from half, in particular adjacent to the bottom edge, are arranged. The belt for connecting the two side parts is guided through a plurality of fastening openings in the side parts. This ensures a consistent positioning of the belt. The mounting holes can have different geometries. Since side parts and seat part are connected in the region of the upper edges by the covering part, the belt and thus also the fastening openings are arranged in the lower half of the side parts. It has been found that an arrangement of the fastening openings near the bottom edge is particularly favorable, since the power flow is guided so optimally far through the side surfaces. A long guidance of the power flow is favorable for building up a bending stress in the parts.

It is further provided that the tensile forces receiving connecting element in the form of the belt has a substantially rectangular cross-section and the attachment openings are designed as slots which are dimensioned equal to or greater than the cross section of the belt, and wherein there is a sliding fit between the belt and mounting holes. For the connection between side panels and belts forces must be transmitted. Cheaper way done this also by an adapted shape between belt and mounting holes. The belt has a substantially rectangular cross-section. Such a belt may for example be formed of leather. Such leather straps have a smooth and a rough side. Adapted to the rectangular cross-section of the belt, the mounting holes are designed as slots, the length of the slots substantially equal to the width of the belt and the height of the slots substantially equal to the height of the belt. In order to easily insert the belt into the slots, the slots are the same or slightly larger than the belt dimensioned. Thereby, a sliding seat is formed, which allows the belt can be threaded in the unloaded state in the mounting holes. At the same time, however, such a sliding seat on no unnecessary play, which favors a frictional connection between the belt and mounting holes in the use state in which the belt is under tension.

It is advantageous that the attachment openings are arranged in pairs and thereby form pairs of openings, wherein the belt in the use state by an attachment opening of an opening pair of an inner side of the side part to an outside of the side part and guided through the other attachment opening of this opening pair in the opposite direction from the outside is guided to the inside of the side part. The belt extends in the state of use from a mounting opening of an opening pair out and directly into the adjacent mounting holes of the same opening pair. As a result, the belt is deflected twice within a short distance. This deflection occurs both times approximately at 90 ° angle. This double deflection at a short distance holds the belt particularly well in the adjacent attachment openings. The belt is held in place by the static friction within the mounting holes. If the belt is put under tension, it additionally deforms in the region of the edges of the fastening openings, whereby a positive connection is created, which fixes the belt in the region of the opening pair, so that it is firmly connected to the side part. When the tension is released again, for example when assuming the bearing condition, the deformation of the belt in the edge region of the fastening openings diminishes and the belt can be easily pulled out of the fastening openings. To be particularly favorable, an embodiment of the mounting holes has proven to be long holes. Preferably, these slots have a length between 6.5 and 15 mm, more preferably between 8.5 and 12.5 mm. The width of these slots is conveniently between 2 and 5 mm, more preferably between 3.3 and 3.8 mm. The belt is conveniently made equal or slightly smaller in cross-section than these dimensions.

Conveniently, it is provided that the belt is guided in the use state of an opening pair of a side part to an opening pair of the opposite side part, starting at a arranged on a side edge of a first side part opening pair of the belt to the side edge of the next seen opening pair of the opposite, second side part is guided, and from there the belt is then guided to the side edge of the third pair of openings of the first side part, and wherein the belt according to this pattern alternately runs from one side part to the other and each side part is guided only by each second opening pair , In this embodiment, the two side parts are connected by the belt in a pattern which is similar to the lacing of a shoe. In a side part is along the bottom edge extending and a number of pairs of openings provided. The belt is initially threaded into an outermost opening pair of a side part. From there, it is guided diagonally to the second opening pair, viewed from the side edge, of the opposite side part. From this pair of openings, it again runs back to the first side part and is guided there by the third pair of openings viewed from the side edge. Through this guide, which uses only every second pair of openings in each side part, the belt runs zigzag between the two side parts. Once the initial threading opposite end is reached, the belt is guided back in the direction of the initial threading, where now the unoccupied opening pairs are used. The result is a pattern of oppositely diagonal belt areas. As a result of this pattern, the two side parts are joined together in a particularly effective manner, since the diagonal course of the belt areas produces forces along the bottom edge of the side parts as well as forces that run at right angles to the bottom edge. As a result, a bending stress is effectively generated in the side parts and in the seat part connected to the side parts via the covering part, which in turn ensures the stability of the folding stool.

It is envisaged that in the state of use of the belt is under tension and in this state of the tension of the belt is frictionally engaged with each of the belt penetrated opening pair in operative connection, so that the belt is fixed in position relative to the side part. In particular, by the combination of fastening openings, which are arranged as pairs of openings and the previously described A pattern in which the belt runs between the side parts creates an effective, non-positive and also positive connection between the belt and the side parts as soon as the belt is put under tension. This tension arises from the fact that the belt is pulled during assembly or during the transfer to the user state of the building person as far or so long through the mounting holes until the side parts and the seat part deform elastically. Once this tension has been applied, the belt is firmly fixed to the side parts without the need for further fixing means. This allows an easy and fast construction of the Falthockers. No tool is needed to set the usage state of the folding stool. As a result, the handling of the Falthockers is particularly simple. Of course, in addition to the described mechanisms, further fastening elements for the belt can be provided on the side parts.

In a particularly favorable embodiment it is provided that four pairs of openings are provided in each side part. Experiments have shown that four pairs of openings per side provide for a particularly good stability of the Falthockers. Of course, however, other numbers of opening pairs per side part can be provided.

In a preferred embodiment it is provided that the side parts and the seat part made of a flexible elastic wood material, in particular a multi-layered wooden material. A well-suited material for side parts and seat part is plywood, which has a very good dimensional stability. Due to the layered structure of plywood whose mechanical properties, in particular its flexural rigidity in all directions are homogeneous. A particularly high flexural strength, combined with a low weight has birch plywood. In particular, thin-layered birch plywood, as used in aircraft, is very well suited for a Falstocker, since it has a very low weight at high strength. Such birch plywood from the aircraft industry has layer thicknesses of less than 1 mm and consists of more than five layers. Of course, parts of the Falthockers can also be made of other materials, such as metals, plastics or fiber composites.

It is provided that the covering part has a lens-shaped area as a seating surface. The covering part is connected to the seat part and the side parts. In the area where the covering part rests on the seat part, a seating surface is provided on the covering part. This seat is conveniently designed substantially lenticular and has two longitudinally oriented, curved edges. A lenticular seat is used together with a likewise lenticular seat part. This shape, which approximates a saddle, makes it possible to sit and execute rocking movements on the folding stool in a particularly comfortable way. The seat comprises the center piece and the connecting edges of the covering part.

In a preferred embodiment it is provided that the covering part adjacent to each pointed end of the lenticular seat surface has a substantially triangular running area, wherein a tip of this triangular area is connected to the tip of the lens-shaped area, preferably made in one piece. This embodiment is adjacent, in particular provided on both sides adjacent to the seat a triangular executed area of the covering part. This triangular area is intended to make another connection between the two side panels.

It is expediently provided that the side parts have side edges which respectively connect the ends of the upper edge and the bottom edge to one another and the side edges are connected to one side of a triangularly executed region of the covering part. The side parts have further outer edges, the side edges, which extend between the outer ends of the upper edge and bottom edge. In a simple embodiment, the side edges are rectilinear. However, the side edges may also have a different geometry and be designed, for example, arcuate. The side edges are connected to outer edges of the triangular running portion of the covering part.

It is provided that in the state of use, the triangular areas of the covering part are folded between the side edges of the side parts. By folding the triangular areas between the side edges creates a padding or cushioning between the adjacent side edges at this point. This ensures that the Falthocker produces no noise when it is used for rocking movements. The support between the two side edges is damped by the folds.

It is particularly advantageous that adjacent to the side edges mounting holes are arranged through which tensile forces receiving additional connection elements, such as additional belts, are guided, which additionally connect the side panels in the use state. Through a combination of mounting holes and additional straps in the area of the side edges, between which the triangular running portion of the covering part is folded, an additional fixed connection is generated at this point. This facilitates the build-up of bending stress in the flexurally elastic parts of the folding stool.

It is advantageously provided that the covering part consists of leather, in particular of laminated leather. Leather is a natural material that creates a pleasant feeling when sitting on the Falthocker. Since the seat part is usually made of wood, causes a leather covering part, which is arranged above the seat part and forms the seat, a padding for the user of the Falthockers. It has been found to be advantageous for the covering part laminated leather to use. By laminating a fabric is applied to the underside of the leather, which absorbs initiated tensile forces. Thus, it is ensured that the leather does not stretch during use of the folding stool and thereby the bending stress in the side parts and the seat part is maintained.

It is particularly advantageous that the covering part is connected by at least one seam with the side parts and the seat part, wherein the seam is preferably introduced by means of a commercially available industrial sewing machine. A connection of the parts by seams is long-term stable and reliable. Surprisingly, it has been found that a made of leather covering part with thin plywood made of side panels and seat part can be simply sewn with a standard sewing machine. Thus, the seams can be made quickly in a simple manner. Of course, it is also possible to connect the parts of the Falthockers with other joining techniques, such as by gluing, riveting or by brackets or fittings with each other.
