Definitions
- the present invention relates to a seating furniture having a seat which is adapted to be rocked about a swiveling axis extending parallel to said seat, wherein the angle of swing about the swiveling axis is limited.
- a beam which extends parallel to the seat and perpendicular to the tubular element and having a certain distance from the floor, is connected to the central supporting tube.
- a seating furniture having a seat which is adapted to be rocked about a swiveling axis extending parallel to the seat, wherein the angle of swing about the swiveling axis is limited by at least two limiting elements being attached to the seating furniture preferably in a region of the seat and extending away from the seat towards opposite sides relative to the swiveling axis.
- the two limiting elements are both attached to the seating furniture in a region of the seat, e.g. directly to the seat.
- a first one of the limiting elements is attached to the seating furniture in a region of the seat and a second one of the limiting elements is attached to the seating furniture in a region of a back-rest thereof, e.g. directly to the back-rest.
- the limiting elements which are arranged in the region of the seat or the back-rest, may be directly attached to the seat or the back-rest.
- the limiting elements may also be attached to the seating furniture at a short distance away from the seat or the back-rest, e.g. to an element which is coupled with the seat like a supporting tube which is stationary or rotatable with respect to the seat.
- the at least two limiting elements may also be designed as an integral, e.g. plane, structure, provided that the integral structure comprises portions extending away from the seat towards opposite sides relative to the swiveling axis. Said portions of the integral structure then form the limiting elements according to the invention.
- a seating furniture comprising two, three, four or more limiting elements, which are attached on opposite sides relative to the swiveling axis in the region of the seat, e.g. on the lower seat surface or at the periphery of the seat, can be easily manufactured. Furthermore, a seating furniture of such configuration has an increased stability over conventional seats with a rocking seat.
- the seat may for example take the form of a square, a circle, a triangle, a cross, a polygon or a lying eight.
- substantially X-shaped seats are used. Sitting in a position which is of particular advantage in view of ergonomics can be ensured because of the substantially X-shaped configuration of the seat. This is due to the fact that an X-shaped seat is, on the whole, experienced to be most comfortable in a plurality of possible sitting positions, for example inclined backwards, forwards, to the left or to the right relative to the sitting direction.
- the advantages of the X-shaped seat become particularly apparent when the sitting direction is changed relative to the swiveling axis, i.e. when another sitting position is chosen.
- the X-shaped seat it can be ensured that the sitting comfort is kept constantly high, regardless of whether e.g. a sitting direction parallel or perpendicular to the swiveling axis is chosen.
- the X-shaped seat is also advantageous because it allows easy stacking of seating furniture.
- the position of the swiveling axis relative to the sitting direction may preferably be freely chosen by the person being seated on the seat. There may be at least two different sitting positions available to a person being seated, i.e. the person may chose e.g. between sitting directions perpendicular or parallel to the swiveling axis.
- the swiveling axis may also form an acute angle of more than 0° and less than 90° with the sitting direction.
- the swiveling axis is advantageously arranged in the region of the floor, i.e. directly in the plane of the floor or slightly above it.
- the limiting elements may form an angle between 65° to 85°, and in particular between 70° to 80°, with the seat in such a manner that the spacing between the limiting elements increases as the distance from the seat increases. Furthermore, the limiting elements are preferably disposed in the region of opposed ends of the seat.
- the limiting elements are most preferably provided in pairs, wherein an imaginary connecting line between individual limiting elements of a pair may extend perpendicular to the swiveling axis. In particular, exactly two limiting elements may be provided, the imaginary connecting line of which extends perpendicular to the swiveling axis and passes through a central point in the middle of the seat.
- the limiting elements may be designed as legs in the manner of the legs of a chair and may have a substantially cylindrical shape.
- the swiveling axis extending parallel to the seat, is defined by a supporting structure, which is preferably attached in the region of the lower seat surface and which extends towards the floor.
- the seat may be rotatable relative to the supporting structure about an axis extending perpendicular to the seat.
- the supporting structure may also be configured such that it may be arrested in various angular positions relative to the seat.
- the supporting structure is defined by two or more separate legs. One leg each may for example be disposed on opposite ends of the seat.
- the swiveling axis thus matches with the imaginary connecting line of the ends of the two legs facing the floor.
- the legs of the supporting structure may thus form an angle between 70° to 88°, preferably between 75° to 85°, with the seat in such a manner that the spacing between the legs increases as the distance from the seat increases.
- the supporting structure which defines the swiveling axis, comprises a central supporting element, which is e.g. disposed on the lower seat surface. At its end facing away from the seat the supporting element may comprise an element, which extends parallel to the seat and defines a swiveling axis extending perpendicular to the supporting element.
- the supporting structure has thus substantially the form of an upside-down T.
- the supporting element as well as the element defining the swiveling axis may for example be tubular in shape.
- the supporting structure is formed as a plane or frame-like element, e.g. in the form of a rectangle being disposed at the lower seat surface.
- the seat, the limiting elements and the supporting structure, which define the swiveling axis, may be vertically adjustable so that the seating furniture may individually be adapted to the height of a person or the working environment of the person, respectively. It is also possible to make any of these components resilient or to provide any of these components with a resilient member in order to increase the sitting comfort. Moreover, it is also conceivable to make said components detachable. In this manner it is possible to reduce the space requirements of the seat, which facilitates transportation thereof. Transportation can also be facilitated if the seating furniture has a foldable construction.
- the seat may further comprise a back-rest.
- the back-rest is preferably of such functionality that it provides a uniformly good hold in various sitting directions relative to the swiveling axis.
- the seat comprises, in a peripheral region, i.e. at the edge, a receiving aperture for the back-rest so that the back-rest may be detachably connected with the seat.
- the seat preferably comprises at least one further receiving aperture, which is offset relative to the first receiving aperture by an angle of from 45° to 90° relative to an axis extending perpendicular to the seat and passing through the center of the seat.
- the back-rest may thus be detachable and adapted to the respective sitting position by changing between the two receiving apertures.
- a back-rest may be provided which may be swiveled either continuously or between predetermined angular positions about an axis extending perpendicular to the seat.
- the back-rest may have a shaft, which comprises, at an end facing away from the seat, a supporting member.
- the supporting member is preferably configured such that it may be attached to the shaft in at least two different positions.
- the supporting member may thus be arranged for example in a first position parallel to the sitting direction and in a second position perpendicular to the sitting direction.
- the seat preferably comprises two sections extending perpendicular to each other, wherein the swiveling axis may extend parallel to the first section of the X and perpendicular to the second section of the X. It is possible to dispose the limiting elements in the region of opposite ends of the first section and to dispose the legs, defining the swiveling axis, in the region of opposite ends of the second section.
- the seat may be upholstered. Furthermore, it may be curved downwards (concave) or curved upwards (convex) with respect to the floor.
- the concave or convex shape may be realized by making both sections U-shaped, wherein the ends of each section are at a greater or lesser distance from the floor than the respective centers of the sections.

Abstract
A seating furniture has a seat which is adapted to be rocked about a swiveling axis extending parallel to the seat. The seat comprises at least two limiting elements for limiting an angle of swing about the swiveling axis. The limiting elements are attached to the seating furniture in a region of the seat and extend, relative to the swiveling axis, towards opposite sides of the floor.
Description
- 1. Technical Field of the Invention
- The present invention relates to a seating furniture having a seat which is adapted to be rocked about a swiveling axis extending parallel to said seat, wherein the angle of swing about the swiveling axis is limited.
- 2. Description of the Prior Art
- A seating furniture having a rocking seat is known for example from DE 199 14 643 A1. A downward extending supporting tube is disposed at the center of the seat on a lower surface thereof which faces the floor. A tubular element, the longitudinal axis of which defines a swiveling axis extending perpendicular to the sitting direction and parallel to the seat, is attached to the supporting tube perpendicular to the sitting direction in a region of the floor. The sitting direction is the direction in which a person looks after being seated on the seating furniture.
- A beam, which extends parallel to the seat and perpendicular to the tubular element and having a certain distance from the floor, is connected to the central supporting tube. When the ends of the beam touch the floor during a rocking motion, a further turning about the swiveling axis is prevented and thus a tilting of the seating furniture avoided. Consequently, the angle of swing about the swiveling axis is limited by means of the beam. The object of the present invention is to provide a seating furniture having enhanced functionality and which is of advantage in view of ergonomics.
- Said object is achieved according to the present invention by a seating furniture having a seat which is adapted to be rocked about a swiveling axis extending parallel to the seat, wherein the angle of swing about the swiveling axis is limited by at least two limiting elements being attached to the seating furniture preferably in a region of the seat and extending away from the seat towards opposite sides relative to the swiveling axis. According to a first variant of the invention, the two limiting elements are both attached to the seating furniture in a region of the seat, e.g. directly to the seat. According to a second variant of the invention, a first one of the limiting elements is attached to the seating furniture in a region of the seat and a second one of the limiting elements is attached to the seating furniture in a region of a back-rest thereof, e.g. directly to the back-rest.
- In accordance with the present invention the term “seat” designates the entire element in which the planar or curved two-dimensional area is formed on which a person may sit. In addition to the swiveling axis extending parallel to the seat a swiveling axis extending perpendicular to the seat may also be provided for the seat.
- The limiting elements, which are arranged in the region of the seat or the back-rest, may be directly attached to the seat or the back-rest. The limiting elements may also be attached to the seating furniture at a short distance away from the seat or the back-rest, e.g. to an element which is coupled with the seat like a supporting tube which is stationary or rotatable with respect to the seat. In accordance with the invention the at least two limiting elements may also be designed as an integral, e.g. plane, structure, provided that the integral structure comprises portions extending away from the seat towards opposite sides relative to the swiveling axis. Said portions of the integral structure then form the limiting elements according to the invention.
- A seating furniture comprising two, three, four or more limiting elements, which are attached on opposite sides relative to the swiveling axis in the region of the seat, e.g. on the lower seat surface or at the periphery of the seat, can be easily manufactured. Furthermore, a seating furniture of such configuration has an increased stability over conventional seats with a rocking seat.
- The seat may for example take the form of a square, a circle, a triangle, a cross, a polygon or a lying eight. Preferably, substantially X-shaped seats are used. Sitting in a position which is of particular advantage in view of ergonomics can be ensured because of the substantially X-shaped configuration of the seat. This is due to the fact that an X-shaped seat is, on the whole, experienced to be most comfortable in a plurality of possible sitting positions, for example inclined backwards, forwards, to the left or to the right relative to the sitting direction.
- The advantages of the X-shaped seat become particularly apparent when the sitting direction is changed relative to the swiveling axis, i.e. when another sitting position is chosen. By virtue of the X-shaped seat it can be ensured that the sitting comfort is kept constantly high, regardless of whether e.g. a sitting direction parallel or perpendicular to the swiveling axis is chosen. The X-shaped seat is also advantageous because it allows easy stacking of seating furniture.
- The position of the swiveling axis relative to the sitting direction may preferably be freely chosen by the person being seated on the seat. There may be at least two different sitting positions available to a person being seated, i.e. the person may chose e.g. between sitting directions perpendicular or parallel to the swiveling axis. The swiveling axis may also form an acute angle of more than 0° and less than 90° with the sitting direction. The swiveling axis is advantageously arranged in the region of the floor, i.e. directly in the plane of the floor or slightly above it.
- The limiting elements may form an angle between 65° to 85°, and in particular between 70° to 80°, with the seat in such a manner that the spacing between the limiting elements increases as the distance from the seat increases. Furthermore, the limiting elements are preferably disposed in the region of opposed ends of the seat. The limiting elements are most preferably provided in pairs, wherein an imaginary connecting line between individual limiting elements of a pair may extend perpendicular to the swiveling axis. In particular, exactly two limiting elements may be provided, the imaginary connecting line of which extends perpendicular to the swiveling axis and passes through a central point in the middle of the seat. The limiting elements may be designed as legs in the manner of the legs of a chair and may have a substantially cylindrical shape.
- The swiveling axis, extending parallel to the seat, is defined by a supporting structure, which is preferably attached in the region of the lower seat surface and which extends towards the floor. The seat may be rotatable relative to the supporting structure about an axis extending perpendicular to the seat. The supporting structure may also be configured such that it may be arrested in various angular positions relative to the seat. In accordance with a preferred embodiment of the present invention the supporting structure is defined by two or more separate legs. One leg each may for example be disposed on opposite ends of the seat. The swiveling axis thus matches with the imaginary connecting line of the ends of the two legs facing the floor. The legs of the supporting structure may thus form an angle between 70° to 88°, preferably between 75° to 85°, with the seat in such a manner that the spacing between the legs increases as the distance from the seat increases.
- In accordance with a second embodiment of the present invention the supporting structure, which defines the swiveling axis, comprises a central supporting element, which is e.g. disposed on the lower seat surface. At its end facing away from the seat the supporting element may comprise an element, which extends parallel to the seat and defines a swiveling axis extending perpendicular to the supporting element. The supporting structure has thus substantially the form of an upside-down T. The supporting element as well as the element defining the swiveling axis may for example be tubular in shape.
- In accordance with a third embodiment of the present invention the supporting structure is formed as a plane or frame-like element, e.g. in the form of a rectangle being disposed at the lower seat surface.
- The seat, the limiting elements and the supporting structure, which define the swiveling axis, may be vertically adjustable so that the seating furniture may individually be adapted to the height of a person or the working environment of the person, respectively. It is also possible to make any of these components resilient or to provide any of these components with a resilient member in order to increase the sitting comfort. Moreover, it is also conceivable to make said components detachable. In this manner it is possible to reduce the space requirements of the seat, which facilitates transportation thereof. Transportation can also be facilitated if the seating furniture has a foldable construction.
- The seat may further comprise a back-rest. The back-rest is preferably of such functionality that it provides a uniformly good hold in various sitting directions relative to the swiveling axis. In accordance with one embodiment the seat comprises, in a peripheral region, i.e. at the edge, a receiving aperture for the back-rest so that the back-rest may be detachably connected with the seat. The seat preferably comprises at least one further receiving aperture, which is offset relative to the first receiving aperture by an angle of from 45° to 90° relative to an axis extending perpendicular to the seat and passing through the center of the seat. The back-rest may thus be detachable and adapted to the respective sitting position by changing between the two receiving apertures. Instead of a detachable back-rest, also a back-rest may be provided which may be swiveled either continuously or between predetermined angular positions about an axis extending perpendicular to the seat.
- The back-rest may have a shaft, which comprises, at an end facing away from the seat, a supporting member. The supporting member is preferably configured such that it may be attached to the shaft in at least two different positions. The supporting member may thus be arranged for example in a first position parallel to the sitting direction and in a second position perpendicular to the sitting direction.
- In case the seat is X-shaped, the seat preferably comprises two sections extending perpendicular to each other, wherein the swiveling axis may extend parallel to the first section of the X and perpendicular to the second section of the X. It is possible to dispose the limiting elements in the region of opposite ends of the first section and to dispose the legs, defining the swiveling axis, in the region of opposite ends of the second section.
- In order to increase the sitting comfort the seat may be upholstered. Furthermore, it may be curved downwards (concave) or curved upwards (convex) with respect to the floor. In case of an X-shaped seat the concave or convex shape may be realized by making both sections U-shaped, wherein the ends of each section are at a greater or lesser distance from the floor than the respective centers of the sections.
