Chair Guiding Device Comprising a Tilting Plate

Abstract

A chair guiding device including: a rail guide that extends between a starting and an end position of a chair receptacle; a carriage, which carries the chair receptacle and is displaceably mounted on the rail guide; and a housing, comprising a base body and a cover on which an elongated hole is incorporated, in which the chair receptacle is arranged so as to be movable back and forth. The rail guide is arranged pivotably about a rotational axis. The rail guide is arranged on a tilting plate, which is pivotably mounted on a revolute joint comprising the rotational axis. The tilting plate, together with the rail guide, is surrounded at least partially by the housing; and a means is provided that can pivot the tilting plate by an angle (α) relative to the horizontal plane EB.

I claim: 
     
         1 . A chair guiding device ( 100 ), comprising:
 a rail guide ( 6 . 1 ,  6 . 2 ), which extends between a starting and an end position (A; E) of a chair receptacle ( 4 );   a carriage ( 5 ), which carries the chair receptacle ( 4 ) and is displaceably mounted on the rail guide ( 6 . 1 ,  6 . 2 ); and   a housing ( 10 ), comprising a base body ( 17 ) and a cover ( 11 ) on which an elongated hole ( 3 ) is incorporated, in which the chair receptacle ( 4 ) is arranged so as to be movable back and forth, characterized in that:   the rail guide ( 6 . 1 ,  6 . 2 ) is arranged pivotably about a rotational axis ( 24 );   the rail guide ( 6 . 1 ,  6 . 2 ) is arranged on a tilting plate ( 20 ), which is pivotably mounted on a revolute joint ( 22 ) comprising the rotational axis ( 24 );   the tilting plate ( 20 ), together with the rail guide ( 6 . 1 ,  6 . 2 ), is surrounded at least partially by the housing ( 10 ); and   a means ( 23 ) is provided that can pivot the tilting plate ( 20 ) by an angle (α) relative to the horizontal plane (EB).   
     
     
         2 . The chair guiding device according to  claim 1 , characterized in that the horizontal plane (EB) is defined by a bottom ( 12 ) of the base body ( 17 ) or by the cover ( 11 ). 
     
     
         3 . The chair guiding device according to  claim 1 , characterized in that the means ( 23 ) is a spring element ( 23 . 1 ) or another means, for example an eccentric element. 
     
     
         4 . The chair guiding device according to  claim 3 , characterized in that:
 the spring element ( 23 . 1 ) exerts a spring force (FK) that is greater than the weight acting on the spring as a result of the weight of the chair ( 1 ), tilting plate ( 20 ), and chair receptacle ( 4 ) so that the tilting plate ( 20 ) is pivoted by the angle (α) relative to the horizontal plane in any chair position when the chair is not occupied;   the spring element is compressed in the loaded state of the tilting plate ( 20 ) so that the tilting plate ( 20 ) assumes a horizontal position ( 31 ) that is plane-parallel to the plane (EB); and   the spring element pushes against the tilting plate ( 20 ) with a spring force (FK) that is directed substantially perpendicular to the tilting plate ( 20 ).   
     
     
         5 . The chair guiding device according to  claim 3 , characterized in that the spring element ( 23 . 1 ) is a coil spring. 
     
     
         6 . The chair guiding device according to  claim 3 , characterized in that the spring element ( 23 . 1 ) is a gas pressure spring. 
     
     
         7 . The chair guiding device according to  claim 3 , characterized in that the spring element ( 23 . 1 ) is made of an elastomeric material. 
     
     
         8 . A chair guiding device according to  claim 1 , characterized in that the spring element ( 23 . 1 ) is mounted on the bottom ( 12 ) of the housing ( 10 ). 
     
     
         9 . A chair guiding device according to  claim 1 , characterized in that the sloped position ( 30 ) of the tilting plate ( 20 ) in the unloaded state corresponds to an angle of inclination (α) of 0° to 15°, preferably 1° to 3°. 
     
     
         10 . A chair guiding device according to  claim 1 , characterized in that the tilting plate ( 20 ) is formed by the bottom ( 12 ). 
     
     
         11 . A chair guiding device according to  claim 1 , characterized in that the housing ( 10 ) is cuboid. 
     
     
         12 . A chair guiding device according to  claim 1 , characterized in that the housing ( 10 ) is suited for installation in a base plate of an office chair or of a relaxation armchair. 
     
     
         13 . A chair guiding device according to  claim 1 , characterized in that the cover ( 11 ) of the housing ( 10 ) comprising an elongated hole ( 3 ) can be replaced with a cover having no elongated hole. 
     
     
         14 . A chair guiding device according to  claim 1 , characterized in that the fastening elements used for fastening the chair receptacle ( 4 ) can be accessed from outside the housing ( 10 ).
