Rollable piece of furniture
The invention relates to a rollable piece of furniture comprising: 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 in relation to a rolling axis, wherein, in the unrolled state, the surface elements adjoin each other at least partially with their respective side surfaces and are bent in relation to the rolling axis and have a non-rectilinear course in such a way that the side surfaces are exposed to pressure when the piece of furniture is loaded as intended.
1 . Rollable piece of furniture comprising:
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 in relation to a rolling axis, wherein,
in the unrolled state, the surface elements adjoin each other at least partially with their respective side surfaces and are bent in relation to the rolling axis and have a non-rectilinear course in such a way that the side surfaces are exposed to pressure when the piece of furniture is loaded as intended.
2 . Rollable piece of furniture according to claim 1 , wherein
the surface elements each have a longitudinal axis extending along the direction of the rolling axis, and
a height, which defines a distance between the side surfaces of the respective surface element, of surface elements of the plurality of surface elements, which in the unrolled state are located in the region of a curvature of a shape of the piece of furniture, changes along the longitudinal axis.
3 . Rollable piece of furniture according to claim 1 , wherein
the surface elements each have a longitudinal axis extending along the direction of the rolling axis, and
the surface elements are shaped in such a way that a distance between a surface facing the rolling axis, which connects the side surfaces of the respective surface element with each other, and the rolling axis at end portions along the longitudinal axis is different and varies.
4 . Rollable piece of furniture according to claim 1 , wherein
the side surfaces of the flexibly connected surface elements adjoin flat against each other and preferably have the same surface area.
5 . Rollable piece of furniture according to claim 1 , wherein
the surface elements are flexibly connected to each other by connecting elements, which are exposed to tension when the piece of furniture is loaded as intended.
6 . Rollable piece of furniture according to claim 3 , wherein
the distance between the respective surface facing the rolling axis and the rolling axis is smaller at end portions at ends of the respective surface elements lying in the direction of the longitudinal axis than at a center portion located between the ends lying in the direction of the longitudinal axis.
7 . Rollable piece of furniture according to claim 1 , wherein
the shape of the piece of furniture in the unrolled state corresponds to a chair comprising the following regions:
a base region in which the chair contacts a ground surface,
a load region, which is arranged above the support region and in which the intended load is applied to the chair, and
a support region connecting the base region and the load region.
8 . Rollable piece of furniture according to claim 7 , wherein
the shape of the piece of furniture in the unrolled state describes an arc in the support region, in that the height at the end portions at the ends of the respective surface elements lying in the direction of the longitudinal axis is greater than the height at the center portion, which is located between the ends lying in the direction of the longitudinal axis.
9 . Rollable piece of furniture according to claim 7 , wherein
the shape of the piece of furniture in the unrolled state corresponds to a chair further comprising the following regions:
a backrest region that supports a back of a person sitting on the load region and extends vertically to the load region, and
a further support region connecting the load region and the backrest region.
10 . Rollable piece of furniture according to claim 9 , wherein
the shape of the piece of furniture in the unrolled state describes an arc in the further support region, in that the height at the end portions at the ends of the respective surface elements lying in the direction of the longitudinal axis is smaller than the height at a center portion, which is arranged between the ends lying in the direction of the longitudinal axis.
11 . Rollable piece of furniture according to claim 1 , wherein
the shape of the piece of furniture in the unrolled state corresponds to a table comprising the following regions:
a load region, in which the intended load is applied to the table and which defines a deposit surface of the table,
a plurality of side regions that support the load region against a ground surface, and
a plurality of transition regions connecting the load region with the plurality of side regions.
12 . Rollable piece of furniture according to claim 11 , wherein
the surface elements are shaped in such a way that the distance between the surface elements and the rolling axis is constant in a central portion, which is located between the ends of the respective surface elements lying in the direction of the longitudinal axis and corresponds to the load region.
13 . Rollable piece of furniture according to claim 1 , wherein
the surface elements are stabilized in the unrolled state by a tension belt in such a way that the piece of furniture retains the shape of the piece of furniture in the unrolled state in an unloaded state.
14 . Rollable piece of furniture according to claim 13 , wherein
the tension belt runs in passages, which are formed in the respective surface elements, in such a way that it is not visible from the outside when the piece of furniture is the unrolled state.
