  • the invention relates to a piece of furniture that can be rolled up, in particular a chair or table that can be rolled up.
  • US Pat. No. 734,4197 B2 shows a chair that can be rolled up for storage or portability.
  • the supporting structure of the chair consists of two chain-like connecting elements on which slat-like elements are arranged at certain distances from one another and form the surface of the chair.
  • the chain-shaped elements are each solid, heavy and stable. This significantly increases the volume and weight of the chair, negatively affecting portability and storage.
  • the piece of furniture that can be rolled up according to the invention has the following: a plurality of surface elements arranged next to one another, which are flexibly connected to one another in such a way that the piece of furniture can be transferred from a rolled-up state to an unrolled state with respect to a roll axis the surface elements in the unrolled state at least partially abut each other with respective side surfaces and are bent in relation to the rolling axis in such a way and have a non-linear course that the side surfaces are subjected to pressure when the piece of furniture is loaded as intended.
  • the piece of furniture according to the invention is in particular a chair or a table.
  • the surface elements arranged next to one another are preferably connected to one another in a flexible/rotatable manner via connecting elements and together form a surface of the piece of furniture when unrolled.

  • Different shapes of the piece of furniture according to the invention can be formed and defined by individually designing the surface elements arranged next to one another.
  • the surface elements each have a longitudinal axis, which runs in the direction of the roll axis, with a height, which defines a distance between the side surfaces of the respective surface element, of such surface elements
  • Plurality of surface elements which are in the region of a curvature of a shape of the piece of furniture in the unrolled state, preferably changes along the longitudinal axis.
  • the longitudinal axes of the surface elements preferably run parallel to one another and parallel to the rolling axis.
  • the curvature of the shape of the piece of furniture is determined in particular by the individual configuration of the surface elements arranged next to one another.
  • the height of the surface elements at a central section is, for example, a minimum or a maximum, depending on which direction of curvature the curvature has and how strong the curvature is.
  • the surface elements preferably each have a longitudinal axis which runs in the direction of the roll axis, with the surface elements preferably being shaped in such a way that there is a distance between a surface facing the roll axis, which connects the side surfaces of the respective surface element to one another, and the roll axis along sections of the longitudinal axis is different/varies.

  • the first side surfaces S1′ and the second side surfaces S2′ of adjacent surface elements 1301′ to 1317′ preferably rest against one another over their entire surface and preferably have the same surface area. Since there is a straight course in the load area 13' in the second exemplary embodiment, the first side surfaces S1' and the second side surfaces S2' are aligned parallel to one another.
  • the surface elements 131' to 1317' it is preferable for the surface elements 131' to 1317' to lie flat on top of one another, since pressure loads which occur as a result of the applied force F are distributed over a larger area and have an advantageous effect on the stability of the table 2.
  • materials are preferably used which are light, can withstand pressure well and have good rigidity.
  • materials are preferably used which are light, can withstand pressure well and have good rigidity. Examples of appropriate materials are wood, polymers, fiber composites and light metals.
  • reinforcement cores or tension belts can be provided for further stabilization and reinforcement of the table 2 .
  • cover caps as they were described with reference to the previous embodiment.
  • FIG. 10 shows a perspective view of the table 2 in its rolled-up state and FIG. 11 shows a corresponding longitudinal section along line B-B from FIG.
  • the table 2 In the rolled-up state, the table 2 has a shape that resembles the shape of a barrel due to the non-linear course of the surface elements 1301' to 1317' (10') along the longitudinal axis LA'.
  • the table 2 is rolled in by rotating the rotatable joints of the connecting elements 20'. That is, the loading area 13' is rolled up.
  • the loading area 13' can be rolled around the table legs 30'.
  • FIG. 2 shows a perspective view of a piece of furniture 3 that can be rolled up according to a third embodiment of the invention in the unrolled state.
  • the piece of furniture 3 also represents a table 3.
  • the table legs 14 of the table 3 are also constructed by surface elements 10" arranged next to one another, which are flexibly/rotatably connected to one another via connecting elements Figure 12 does not show the subdivision of the table legs 14''.
  • the table 3 can be compared to the chair 1 of the first embodiment from the unrolled state shown, in which the table 3 fulfills its intended function, into a rolled-up state in which the table has a smaller volume and corresponding advantages with regard to transport or storage can be transferred.
  • functional areas of the table 3 can in turn be shaped and defined.
  • the table 3 comprises a loading area 13", two support areas 12" and the table legs 14", which are connected to the support areas 12".
  • the surface elements 10'' are constructed as explained in the second embodiment, which is why reference is made to the corresponding explanations.
  • the surface elements 10'' are constructed as in the further support area of the first embodiment, which is why reference is also made to the corresponding explanations in this regard.
  • the table 3 is rolled in around the roll axis RA" shown.

Abstract

L'invention concerne un article de mobilier enroulable (1) qui comprend : • plusieurs éléments plans (10) qui sont situés les uns à côté des autres et qui sont reliés entre eux de manière flexible de telle sorte que l'article de mobilier (1) peut être transféré d'un état enroulé à un état déroulé par rapport à un axe d'enroulement (RA), dans lequel • à l'état déroulé, des faces latérales respectives (S1, S2) des éléments plans (10) s'appuient au moins partiellement les unes contre les autres et sont pliées par rapport à l'axe d'enroulement (RA) et s'étendent de manière non rectiligne de telle sorte que les faces latérales (S1, S2) sont soumises à une pression lors du chargement de l'article de mobilier.
