Description

The invention disclosed below relates to a device convertible into a seat or a high stand ("learning tower") according to the preamble of claim 1.

The invention disclosed below relates to a device with a cuboid designed in the form of a first frame structure, rods being arranged on a multiplicity of edges to form a frame structure with rigid corners.

Those skilled in the art can arrange rods at the selected edges of the cuboid. Those skilled in the art may alternatively or additionally include rods extending in the side faces of the cuboid (by way of example and not by way of limitation, side face diagonal) and/or rods extending through the space of the cuboid (by way of example and not by way of limitation, space diagonal).

The device disclosed here is not limited to a rod of the first frame structure being arranged on all edges of the cuboid. Bars cannot be placed on selected edges. It is also possible for no bars to be arranged on some edges, thus creating openings. According to current teaching, the person skilled in the art can design the first frame structure to be sufficiently stable in the form of a cuboid.

The first frame structure can also be formed by flat elements, in which case the flat elements can extend, for example and thus not restrictively, in a side face of the cuboid. Since forming the first frame structure from flat elements such as plates would generally involve a great deal of weight, the main focus of the disclosure of the invention is on the formation of the cuboid using rods.

The first frame structure can also comprise a shape similar to the geometric shape of a parallelepiped and a combination of several geometric shapes.

The frame structure also includes at least one surface element. The surface element comprises a seating surface on one surface element side and a standing surface on a surface element side opposite to the seating surface. The surface element can be a plate, one side of which is designed as a seat surface and the other side as a standing surface. The surface element can be arranged essentially horizontally in the first frame structure or at an angle to the horizontal. The surface element can be arranged with an inclination of 1-5 degrees to the horizontal.

WO20200095223 discloses a device convertible to a seat or a stand, but which device does not include a panel having a seating surface on a Surface element side and includes a standing area on the other opposite surface element side.

WO2008061341 discloses a device with a seat surface that can be arranged at different heights by tilting a first frame element. The upper first frame member includes neither a first footprint nor a second footprint. At the in WO2008061341 disclosed device, the surface element is spaced from the tilting axis.

The following documents are included in the international search report WO2008061341 called.

At the in WO2005004674 disclosed device, the frame also includes no second footprint. It is in WO2005004674 does not disclose that the frame can be set up in different positions using different footprints.

In the DE3132086 disclosed device can not be placed in different positions using two different footprints on a base. A position on the designed as armrests 18, in figure 1 above arranged shelves of the frame is not possible because of the backrest 26.

FR7145454 reveals no frame.

FR2269892 does not disclose a first two footprint frame structure.

WO2008031399 discloses a chair with an adjustable seat, which seat can be moved from a position in front of the backrest to a position behind the backrest. It is always the same seat.

In the US5238291 The device disclosed does not include a frame having a first footprint and a second footprint.

In the DE10352610 The device disclosed also does not include a frame with a first footprint and a second footprint.

DE2421259 , DE10229436 . DE20316254 , DE20009724 , FR2158631A5 , DE9410679U1 do not disclose a device having a first footprint and a second footprint.

In the US66179734 disclosed device can not be placed on different footprints of the frame, since this is not allowed arranged on the top of the frame seat receptacle.

The object of the invention disclosed below is to provide a device which can easily be converted from a seat device to a high stand ("learning tower").

This is achieved by claim 1 according to the invention.

• die erste Rahmenstruktur eine erste ebene Stellfläche und eine zweite ebene Stellfläche aufweist, welche zweite Stellfläche zu der ersten Stellfläche gegenüberliegend angeordnet ist,
• wobei das Flächenelement in einer Höhenlage zwischen der ersten Stellfläche und der zweiten Stellfläche angeordnet ist,
• wobei bei einer ersten Stellung der ersten Rahmenstruktur, welche erste Stellung durch eine Orientierung der ersten Stellfläche zu einem Untergrund oder nach unten definiert ist, das Flächenelement als Sitzfläche und bei einer zweiten Stellung der ersten Rahmenstruktur, welche zweite Stellung durch eine Orientierung der zweiten Stellfläche zu einem Untergrund oder nach unten orientiert ist, das Flächenelement als Stehfläche dient.

The device according to the invention can be characterized in that

• the first frame structure has a first flat footprint and a second flat footprint, which second footprint is arranged opposite the first footprint,
• wherein the surface element is arranged at a height between the first floor space and the second floor space,
• wherein in a first position of the first frame structure, which first position is defined by an orientation of the first footprint towards a base or downwards, the surface element as a seat and in a second position of the first frame structure, which second position is defined by an orientation of the second footprint towards a subsurface or is oriented downwards, the surface element serves as a standing area.

The first frame structure with the shape of a cuboid comprises a surface element which can be used as a seat or as a standing surface depending on the position of the frame structure.

In the first position, the panel can be used as a seat. The first frame structure is arranged in the first position such that the first footprint is oriented toward the ground or downward.

An orientation of the first footprint relative to the ground can be such, for example and not restrictively, that the first frame structure is placed with the first footprint on the ground. For this purpose, the first positioning surface can be in the form of a flat surface. Furthermore, the first frame structure can be held with a further support in such a way that the first floor space is held to the ground or downwards. In both of the cases mentioned here as examples of the orientation of the first positioning surface relative to the ground, the surface element is oriented upwards with a seating surface serving as a seat, so that a person can sit on the seating surface. The seating surface may include padding.

In the second position, the surface element can be used as a standing surface. The first frame structure is arranged such that the second footprint is oriented downward or towards the ground. The surface element serving as a standing area is oriented upwards. It can be achieved by way of example and thus not restrictively, this second position of the surface element in that the first frame structure on the second footprint on the Ground is parked or the first frame structure is held by another support so that the second footprint is oriented to the ground. For this purpose, the second positioning surface can be in the form of a flat surface.

An orientation of one of the shelves to the ground can be achieved, for example, by suspending the first frame structure with a further support while spacing the respective shelves from the ground.

The different orientation of the first frame structure with the first or second surface oriented to the ground and the different orientation of the surface element achieved as a result, so that it can be used as a seat or standing surface, implies that the surface element is firmly attached at a height of the frame structure. The position or position of the surface element in relation to the first frame structure is unchangeable.

The surface element can be arranged at half the height between the first footprint and the second footprint, so that when the first frame structure is set up on the ground, the seat and the standing surface are at the same distance from the ground.

The surface element can also be arranged on the first frame structure closer to the first or second floor space, so that the seating surface and the standing surface can be arranged at different heights relative to the ground.

The first frame structure basically has the geometric shape of a cuboid. The first frame structure can also have other geometric shapes, provided that the other geometric shape also allows the technical effects disclosed here to be achieved.

The invention disclosed here is in no way limited to a cuboid shape of the first frame structure, which is achieved, for example, by the person skilled in the art arranging rods at selected edges of the cuboid so that they result in a rigid structure. The person skilled in the art can also arrange diagonal bars instead of bars at the edges on a side surface or in the space of the cuboid. It is only essential here that a stiff and mechanically resilient structure is created, which suggests the shape of a cuboid or a shape similar thereto.

The device according to the invention can be characterized in that an element arranged above the surface element in the first position is designed as a leaning element.

For example, a bar of the frame structure can serve as a backrest. In a first position of the first frame structure, the reclining rod is arranged above the surface element serving as a seat.

The leaning element is by no means limited to a rigid embodiment such as a rod. The leaning element can also be designed as a band.

The device according to the invention can be characterized in that
an opening is arranged on the edge of the cuboid opposite the leaning element.

By not arranging a rod at the edge of the parallelepiped opposite the backing element and lying above the planar element in a first position, an opening is created through which opening a child can easily climb onto the seat. Such an opening can also be created by cutting out a bar arranged on this edge.

The device according to the invention can be characterized in that
on the surface side of the cuboid opposite the leaning element in the first position above the surface element a seat lock can be introduced.

The seat lock closes an opening in the first frame structure which is arranged opposite the backrest element, so that a child cannot leave the seat. The seat lock can be designed as a movable bar, which bar can be moved between a position forming an opening and a closed position forming the seat lock. This effect can also be achieved by a band serving as seat security. The seat safety device arranged on the side opposite the leaning element can in principle have any shape and configuration, provided that this shape and configuration is suitable for preventing the child sitting on the surface element from leaving the seat.

The device according to the invention can be characterized in that
a leaning rod comprises a leaning surface as a leaning element and can be rotated about a leaning rod axis.

This possible embodiment relates essentially, but not restrictively, to the design of the leaning element as a leaning rod. In order to enable comfortable leaning, the leaning rod can comprise a leaning surface aligned with the seat surface. The backing surface and thus the backing rod can be mounted so as to be rotatable about a backing rod axis in order to allow the inclination of the backing surface to be adjusted in this way. The design of the leaning surface can mean that it extends beyond the second floor space. Rotating the leaning surface and thus the leaning rod can ensure that the leaning rod is brought into a position by turning the leaning surface, in which position the leaning surface does not extend beyond the second positioning surface protrudes and thus does not prevent the first frame structure from being placed on the second footprint.

The leaning rod axis can be arranged eccentrically in the leaning rod, so that in the first position the leaning rod is brought into a position by the weight of the leaning rod in which position a child sitting on the surface element can lean against the leaning surface. In a second position, the leaning rod is brought into a position by its own weight in which position the leaning rod does not protrude beyond the second floor space.

Due to the eccentric mounting of the stool, the stool's own weight and the force of gravity can cause the stool to move into the positions described above.

The device according to the invention can be characterized in that
a footboard is arranged on the side of the cuboid surface opposite the leaning element in the first position below the surface element.

The child sitting on the surface element can support its feet on the footboard.

The device according to the invention can be characterized in that
the footboard is mounted tiltably about a footboard rotation axis, which footboard rotation axis extends between the edges opposite the leaning element and which footboard rotation axis is optionally arranged eccentrically to the footboard.

The footboard can protrude from the shape of the cuboid when the first frame structure is in the first position. The footboard can be mounted eccentrically about a footboard rotation axis, so that in the first position the footboard is in a folded-out position, in which folded-out position the child sitting on the surface element can put his feet on the footboard, and in the second position a folded-in position. In the folded position, the footboard does not protrude from the shape of the cuboid.

The first frame structure can be placed on a base with the first floor space or with the second floor space. The shelves can be created by a flat element and/or by the surfaces of several rods.

By setting up the first frame structure in the first position or in the second position, the surface element is assigned its use as a seat or as a raised stand. The first frame structure can be tilted between positions by one person. With a first frame structure, which first frame structure is tilted between the positions by lifting, the tilting movement is not predetermined and is therefore free.

The device according to the invention can be characterized in that
the first frame structure can be removed or fixed to a second frame structure.

The first frame structure may be supported on the second frame structure in the first position or in the second position. The feature of the fixed mounting is to be understood in such a way that the first frame structure is mounted in such a way that it cannot be removed from the mounting relative to the second frame structure.

The first frame structure can be mounted in the second frame structure in such a way that the first frame structure does not contact a substrate via the first standing area or the second standing area, which is why the technical effect of bringing the first frame structure into contact via the first standing area or the second standing area can be omitted. The first frame structure can thus be reduced to forming a spatial delimitation around the surface element. The formation of the first standing area and the second standing area can be omitted in particular if the first frame structure is mounted in the second frame structure.

The device according to the invention can be characterized in that
the first frame structure is mounted such that it can tilt about an axis relative to a second frame structure.

The first frame structure can be removable via the axis to the second frame structure or it can be mounted so that it cannot be removed.

The transfer of the first frame structure from one position into another position can be achieved, in particular in the case of a fixed mounting, but also in the case of a removable mounting, by tilting the first frame structure about the axis. Those skilled in the art can design the second frame structure in such a way that the second frame structure allows the first frame structure to tilt about the axis.

The device according to the invention can comprise a locking device, which locking device prevents the first frame structure from tilting about the axis.

The locking device may be a pin, which pin extends through a first bore in the first frame structure and through a second bore in the second frame structure in the locked state. The first bore may extend substantially parallel to the axis and at a distance from the axis.

The pin can advantageously be designed in such a way that when the pin is removed from at least one borehole, a further movement, such as a rotary movement, is required in addition to the movement in the direction of the borehole. This has the effect that a child cannot disengage the locking device.

The device according to the invention can be characterized in that
the axis is arranged in the plane of the surface element or at a distance from the surface element.

By arranging the axis in the plane of the surface element, the surface element is arranged at the same level in the first position and in the second position of the surface element. Spacing the axis from the plane of the sheet provides that the sheet is located at different elevations in the positions. The height of the surface element can thus be adapted to the requirements of the surface element when used as a seat or as a standing surface.

The device according to the invention can be characterized in that
the second frame structure has recesses located opposite one another, into which recesses projections formed opposite one another on the first frame structure can be introduced.

The mounting of the first frame element in the second frame element can be formed by the recesses and the projections. The recesses and the projections can form a guide unit. By introducing the projections into the recesses, the first frame unit is supported relative to the second frame unit. The introduction can be a pushing in in the direction specified by the guide unit.

The device can be characterized in that
the second frame structure has recesses at several levels.

The first frame unit can thus be stored at different heights from the second frame unit.

By providing recesses at several heights, the height of the first frame structure can be adjusted in relation to the second frame structure. The person skilled in the art can also provide different height adjustment systems for this. For example, the axle can also be guided through bores, which bores are arranged at different heights in the second frame structure.

In terms of equivalence, the recesses can also be formed in the first frame unit and the projections in the second frame unit. The person skilled in the art arranges the projections and the recesses in the respective frame structures in such a way that the projections and recesses can be brought into engagement with the second frame structure for supporting the first frame structure and that a stable support is provided.

• die zweite Rahmenstruktur eine dritte Stellfläche und eine vierte Stellfläche aufweist,
• welche vierte Stellfläche in einem Winkel von circa 90 Grad zu der dritten Stellfläche angeordnet ist.

The device according to the invention can be characterized in that

• the second frame structure has a third footprint and a fourth footprint,
• which fourth shelf is arranged at an angle of approximately 90 degrees to the third shelf.

The device according to the invention can be characterized in that
the second frame structure comprises a table element that can be arranged on a surface side opposite the fourth floor space.

The footboard 8 can be mounted such that it can tilt about an axis of rotation 9 , which axis of rotation 9 extends between the edges opposite the stool 7 and which axis of rotation 9 is optionally arranged eccentrically to the footboard 8 . The eccentric mounting of the footboard 8 is preferably carried out in such a way that the footboard 8 is folded out in the first position 5 and folded in in the second position. The process of folding and unfolding takes place via the gravity of the footboard, with a limitation of the folding directions being provided. The eccentric mounting of the footboard 8 allows the footboard to be folded in and out during the process of tilting the device.

The first frame structure 1 can further comprise two axle rods 19 which axle rods 19 are connected to the first frame structure 1 . the Figures 1 and 2 show the special case that the axle rods 19 are connected to the first frame structure 1 at a distance from the plane of the surface element 2 extending. The axle rods 19 are arranged in a plane of projection of the longitudinal axis of the cuboid of the first frame structure in order to create a balance. The axle rods 19 form an axle 10 .

The axle bars 19 are connected to the plates 24 of the first frame structure 1 . Since the axle rods 19 in the case of, among other things, figure 4 and 5 illustrated embodiment are not arranged in the extension plane of the surface element 2, the axle rods 19 are designed as two elements that do not extend through the interior of the cuboid of the first frame structure 1.

In principle, other forms of connection of the axle rods 19 and the formation of the axle 10 are also conceivable.

The axle rods 19 can be omitted if only a bearing of the first frame structure 1 on the ground is intended. The axle rods 19 can be designed to be removable from the first frame structure 1 .

the figure 6 and the figure 7 show the second frame structure 1 in the second position 6, with the second footprint 4 facing the ground. The one in the Figure 6, 7 The first frame structure 1 shown and the second frame structure 11 also shown essentially have the features of the frame structures described above. For this reason, further description of the frame structures can be omitted.

The in the Figures 3-5 The first frame structure 1 shown in its first position 5 is connected via the axis 10 defined by the axle rods 19 to an in Figure 3-5 second frame structure 11 arranged below the first frame structure 1 . The mounting of the first frame structure 1 on the second frame structure 11 is preferably such that the first frame structure 1 is mounted in a removable manner from the second frame structure 11 . The second frame structure 11 includes a support for receiving the axle rods 19.

The second frame structure 11 is in the in Figure 3 to 7 The embodiment shown is formed in a merely advantageous manner from plates 26, which plates 26 are rigidly connected to form the second frame structure 1 by means of elements such as a footboard 27 arranged essentially at right angles to the plates 26. Furthermore, a deformation of the second frame structure 2 under load can be prevented by the first frame structure 1 mounted via the axle rods 19 .

The first frame structure 1 is mounted such that it can be tilted about the axis 10 in relation to a second frame structure 11 . The first frame structure 1 preferably has such a low weight that the first frame structure 1 can be tilted about the axis 10 by one person. The first frame structure 1 can be formed from a wood material, for example. The first frame structure 1 is thus by tilting from its first position 5, which is in the Figures 3 to 5 is shown in the in the Figures 6 to 7 shown second position 6 by tilting about the axis 10 transferrable.

The second frame structure 11 has a shape which shape allows the first frame structure 11 to tilt about the axis 10 . The first frame structure 1 is from the Figure 3-5 shown first position 5 by tilting about the axis 10 in the Figures 6-7 shown second position 6 by tilting about the axis 10 transferrable.

The first frame structure 1 extends inside the second frame structure 11.

The device may include a safety device 20 . The axle rods 19 are designed as a screw, which screw can be actuated by hand wheels. By operating the screw contact surfaces of the first frame structure 1 and the second frame structure 11 are pressed together, so that a tilting of the first frame structure 1 to the Axis 10 is prevented. The in the Figures 3-7 The embodiments shown relate to the special case that contact surfaces of the frame structures 1, 11 adjoining the axis 10 are pressed against one another. The handwheels thus act as a safety device 20.

The safety device 20 can further comprise, for example, a pin, which pin extends through a bar of the first frame structure 1 and through a bar of the second frame structure 11 . The safety device 20 is released by pulling the pin out of a rod. Preferably, the pulling of the rod in the form of a linear movement is supplemented by a further movement to be carried out beforehand or at the same time, such as rotating the rod, in order to prevent the safety device 20 from being released unintentionally. In particular, the rod can be pulled in the direction of the inside of the cuboid in order to make it more difficult for a child who is staying on the surface element 2 to release the safety device 20 . The in the Figures 3 to 7 The embodiment shown does not include a pin as a safety device 20.

In the Figure 3-7 The embodiment shown has the special case that the axis 10 is arranged at a distance from the surface element 2 . This ensures that the surface element 2 has different heights in the positions 5 , 6 when it is mounted on the second frame element 11 . However, this embodiment requires that the axle rods 19 are arranged as two separate elements as described above.

The first frame structure 1 extends inside the second frame structure 11. The second frame structure 11 can have opposite recesses 12 on its inner surface, into which recesses 12 projections 13 formed opposite on the outer surfaces of the first frame structure 1 can be introduced. This arrangement of recesses 12 and projections 13 is also conceivable with a different arrangement of the frame structure 1 , 11 such as, for example and not restrictively, an arrangement of the second frame structure 11 inside the first frame structure 1 . The recess 12 can be, for example, a guide unit open on one side, into which guide unit the projection can be introduced. The first frame structure 1 can thus be introduced into the second frame structure 11 and removed from it in a manner similar to a drawer. The introduction or removal of the first frame structure 1 into or out of the second frame structure 11 is therefore a process that can be carried out very easily.

The extension of the first frame structure 1 within the second frame structure 2 is only one possible embodiment. The person skilled in the art can also think of an embodiment without any inventive step, in which embodiment the first frame structure 1 extends outside the second frame structure 2 .

The projections 13 can be mounted so as to be rotatable about the axis 10 in relation to the adjoining bar or surface element 2 of the first frame structure 1 .

The device can be characterized in that the second frame structure 11 has recesses 12 at several levels, as is shown in the sectional view of FIG figure 5 is visible. The first frame structure 1 can thus be introduced into the second frame structure 11 at different heights, similar to a drawer. For this purpose, the second frame structure 11 comprises a plurality of bores 21, through which bores 21 the axle 10 can extend at the respective altitude.

the figure 8 shows a detailed image of the mounting of the first frame structure 1 on the second frame structure 11. It is irrelevant for the discussion of this detail whether the first frame structure 1 is in its first position 5 or in its second position 6.

It is mounted via the axle rod 19 , which axle rod 19 extends as a rod through the first frame element 1 and through the second frame element 11 . The frame elements 1, 11 can be rotated about the axis 10 of the axle rod 19 relative to one another. the figure 8 shows the locked position explained below, in which locked position a twisting of the frame structures 1, 11 relative to one another is prevented. The second frame structure 11 comprises second recesses 12 on its surface facing the first frame structure 1. The first frame structure 1 comprises a projection 13 on its surface facing the second frame structure 11, which projection 13 at the in figure 8 shown embodiment is presented as a separate element by way of example and therefore not restrictively. The element forming the projection 13 is introduced into a first recess 22 formed in the surface of the first frame element 1 facing the second frame structure 11 .

The element forming the projection 13 is preferably designed such that it cannot be rotated relative to the first frame structure 1 about the axis 10 because it is introduced into the first recess 22 formed in the first frame structure 1 . This can be achieved by a suitable form fit that prevents twisting. Furthermore, the element forming the projection 13 is preferably not rotatable about the axis 10 in relation to the second frame structure 11 when introduced into the recess 12 . This can be achieved by designing the recess 12 and the projection 13 in a form-fitting manner that blocks rotation. The axle rod 19 is preferably designed as a screw, which screw can be actuated by a hand wheel acting as a safety device 20 . When the axle rod 19 is tightened as a screw, the frame structures 1, 11 are pressed together at their contact surfaces, as a result of which the projection 13 slides into the first recess 22 in of the first frame structure 1 and is introduced into the second recess 12, so that a change in the position of the frame structures 1, 11 about the axis 10 is prevented. By loosening the screw designed as an axle rod 19, the position can be changed.

The projection 13 and the second recess 13 can form a linear guide unit, so that the first frame structure 1 can be introduced into the second frame structure 11 in a manner similar to a drawer.

The second frame structure 11 comprises a plurality of second recesses 12, which second recesses 12 are arranged at different heights. As a result, the user can arrange the first frame structure 1 at different heights relative to the second frame structure 11 .

As explained above, the first frame structure 1 can be removed from the second frame structure 11, which can essentially be achieved by removing axle rods 19.

This allows further uses, with a possible further use in the figure 9 is shown. The user can screw a table 23 into the bore 21 for receiving the axle rod 19 . The second frame structure 11 can be used as in figure 9 shown serving as a table 23 to the first frame structure 1 in the first position 5.

It's in too figure 9 to see the elongated projection.

the figure 6 shows another possible application of the device according to the invention. It's in the figure 6 the device according to the invention consisting of a first frame structure 1 with a surface element 2 and a second frame structure 11 is shown on the right.

The first frame structure 1 is mounted in the first position 5 on the second frame structure 11, the position of the first frame structure 1 having no influence on the advantageous effect of the device according to the invention presented below. It is mounted via the axis 10 so that the first frame structure 1 and the second frame structure 11 can be adjusted relative to one another by rotating about the axis 10 .

The second frame structure 11 comprises a third footprint 14, on which third footprint the second frame structure 11 is mounted. In addition to the third footprint 14 , the second frame structure 11 includes a fourth footprint 15 , which fourth footprint 15 is arranged at an angle of approximately 90 degrees to the third footprint 14 . While the third footprint 14 is formed by an end face of the second frame structure 11 , the fourth footprint 15 is formed by a side face of the second frame structure 11 .

The provision of a fourth footprint 15 and the connection of the frame structures 1, 11 via the axis 10 allows the arrangement of the first frame structure 1 and the second frame structure 11 as in figure 6 shown on the left. The first frame structure 1 , which first frame structure 1 occupies, for example, its first position 5 , is mounted on the first floor space 3 . The second frame structure 11 lying on the fourth floor space 15 is arranged at an angle of approximately 90° to the first frame structure 1 . The second frame structure 11 can have a plate on a partial area of the side surface opposite the fourth placement surface 15 , which plate serves as a table 23 for a person sitting on the surface element 2 .
