Definitions

• the invention relates to seating with a rocking foot.
• Conventional seating furniture such as chairs or armchairs usually have at least three individual feet or a flat foot, so that at least three-point contact with the floor and thus a firm stand is ensured.
• rocking chairs with two parallel runners are known, which allow a rocking-like movement back and forth.
• the invention has for its object to provide a piece of seating furniture, the foot of which is designed. that a healthy sitting posture is achieved and an aesthetically pleasing design of the seating furniture is made possible.
• This object is achieved in a piece of furniture with a rocking foot in that the foot is supported at the front end with a single contact point and at the rear end with a skid on the floor, the skid being so curved in an oblique direction from the rising level. that your concave side is facing away from.
• the foot of the seating furniture according to the invention only touches the floor at two points and allows a lateral rocking movement around its stable equilibrium position. During this rocking movement, the skid rolls on the floor and the seating furniture performs a wobbling movement around the front contact point.
• the seat furniture thus allows the user to perform lateral hip movements while sitting, so that the spine is constantly kept slightly in motion and the back muscles are strengthened.
• Another advantage of the invention is that the foot, which consists of only one runner and a single contact point, offers a high degree of constructive freedom in the overall design of the seating furniture.
• FIG. 1 A preferred embodiment of the invention is explained in more detail below with reference to the drawing,
• the only drawing figure shows a longitudinal section through an armchair with a spherical segment-shaped seat 10.
• the seat surface is formed by the spherical surface of the spherical segment.
• a spherical backrest cushion 12 is attached to the upper end of a column 14, the longitudinal axis of which coincides with the axis of symmetry of the seat 10.
• the flat underside of the seat 10 is supported on its peripheral edge via roller bearings 16 on an annular runner 18.
• the runner 18 is attached to the upper peripheral edge of a truncated cone-shaped base frame 20.
• the column 14 runs coaxially through the base frame 20 and is rotatably supported in the latter.
• an arm 22 extends at an angle of approximately 60 ° with respect to the column 14 towards the arm 22 (which is angled to the right in the drawing) and is pivotally supported on a foot pin 24 at its front end.
• the term “in front” refers to the direction of view of a user sitting on the armchair.
• the chair only touches the floor 26 at two points, namely at a front contact point, which is formed by the foot pin 24, and at a rear point 28, at which the runner 18 touches the floor.
• the plane of the annular runner 18 forms an angle of approximately 30 ° with the bottom 26. Accordingly, the column 14 is also inclined at an angle of approximately 30 ° to the vertical.
• the runner 18 rolls on the floor 26. and a tipping moment arises that drives the armchair back into its equilibrium position. The longer the arm 22 is, the more stable the equilibrium is and becomes indifferent when the point of contact 24 is directly at the lower end of the column 14.
• the seat 10 with the column 14 and the backrest cushion 12 can be rotated in relation to the runner 18 and the base frame 20 in the exemplary embodiment shown, the movement of the seat 10 is not coupled with the rolling movement of the runner 18. This gives the user the opportunity to change the forward direction of the chair like a swivel chair by rotating the seat with the column 14 around the contact point 24 and thereby making the skid 28 roll on the floor.
• a foot roller is provided instead of the foot pin 24, which is rotatably mounted on all sides at the front end of the arm 22 and rolls on the floor 26. In this case, even if the runner 18 is not rotatable with respect to the seat 10. the armchair as a whole can be rotated around the rear contact point 28.
