Piece of furniture for sitting or lying down on

Abstract

The present invention relates to a piece of furniture (100) for sitting or lying down on, comprising a frame (110) and a base (130) for a mattress or a seat cushion. The base (130) spans a horizontal surface area and has a thickness which extends in the vertical direction. The base (130) is resiliently coupled with the frame (110). The invention is characterized by the provision of a guide element (150) which ensures that a vertically downwardly directed external force applied to the base (130) results in the base (130) being moved in a guided manner vertically downwards relative to the frame (110).

1 .

         2 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the guide element ensures a linearly guided movement. 
     
     
         3 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the guide element ensures that the guided downward movement in the vertical direction has a predefined length of movement. 
     
     
         4 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the resilient coupling has a spring pretension. 
     
     
         5 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the resilient coupling is configured such that, when the external force acting upon the base is reduced, the base moves upward in the vertical direction, and that the guide element ensures that the upward movement is guided in the vertical direction and has a predefined length of movement. 
     
     
         6 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the guide element is a linear guide comprising a rail and a slide movably arranged in the rail, and that the rail is fastened to the lying or sitting frame is fastened to the base, or vice versa. 
     
     
         7 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the guide element comprises an upper stopper and a lower stopper. 
     
     
         8 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein a spring strap is connected to the base on the one hand and to the lying or sitting frame on the other hand, and that the spring strap effects the resilient coupling. 
     
     
         9 . The piece of furniture for sitting or lying down on according to  claim 8 , wherein the spring strap is pretensioned. 
     
     
         10 . The piece of furniture for sitting or lying down on according to  claim 9 , wherein the pretension of the spring strap is adjustable. 
     
     
         11 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the base is divided into a plurality of sections spaced apart from each other and decoupled from each other, and that at least part of the plurality of sections are resiliently coupled with the lying or sitting frame such that an external force directed downward in the vertical direction and acting upon each section of this part of the plurality of sections results in a guided downward movement of the section in the vertical direction relative to the lying or sitting frame. 
     
     
         12 . The piece of furniture for sitting or lying down on according to  claim 11 , wherein part of the plurality of sections comprises a first part and a second part, and that the resilient coupling of the lying or sitting frame with the first part has a first spring constant, and that the resilient coupling of the lying or sitting frame with the second part has a second spring constant, and that the first spring constant differs from the second spring constant. 
     
     
         13 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein at least portions of the base have an inherent stiffness. 
     
     
         14 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the base comprises a first base element and a second base element, and that only the first base element is resiliently coupled with the lying or sitting frame, and that the second base element is arranged on the first base element. 
     
     
         15 . The piece of furniture for sitting or lying down on according to  claim 14 , wherein the second base element comprises a plurality of coil springs which are arranged side by side over the entire surface area and whose spring force acts in the vertical direction. 
     
     
         16 . The piece of furniture for sitting or lying down on according to  claim 1 , wherein the piece of furniture for sitting or lying down on is a bed or a bed couch or a sofa or a chair.
