Piece of furniture with a moveable furniture segment

Abstract

A table having a stationary supporting device and a movable furniture segment and an operating device for moving the furniture segment is provided. The operating device is swivelably movable about a vertical axis and is operatively connected with the table leaf by at least one control device. The control device converts a swiveling movement of the operating device to a furniture segment movement different from the swiveling movement of the operating device. The table having the control device and operating device is particularly advantageous in for a multiphase movement of the movable furniture segment. A connecting link guide can be used in the control device, particularly implemented in the form of a control cam having a control groove by means of which a furniture-segment-side control pin can be displaced for the movement of the movable furniture segment.

1 . A piece of furniture comprising: 
 a stationary supporting device;    at least one furniture segment, which can be horizontally moved with respect to the supporting device; and    an operating device for moving the furniture segment,    wherein the operating device is arranged to be swivelably movable about a vertical axis and is operatively connected with the furniture segment by at least one control device, the control device is arranged to convert a swiveling movement of the operating device to a furniture segment movement different from the swiveling movement of the operating device.    
   
   
       2 . The piece of furniture according to  claim 1 , wherein the control device is arranged to convert the swiveling movement of the operating device to a vertical furniture segment movement.  
   
   
       3 . The piece of furniture according to  claim 1 , wherein the control device has a first control element with a horizontally extending first control groove and a first control pin engaging in the first control groove, the first control element is a control cam which swivels about the vertical axis and is non-rotatably connected with the operating device, and the first control pin is connected in one piece with the furniture segment.  
   
   
       4 . The piece of furniture according to  claim 3 , wherein the control device has a second control element with a control groove equidistantly surrounding the vertical axis and a second control pin engaging in the second control groove, the second control element is a cylinder sleeve swivelable about the vertical axis and non-rotatably connected with the operating device, and the second control pin is connected in one piece with the supporting device.  
   
   
       5 . The piece of furniture according to  claim 4 , wherein the first control element and the second control element are constructed as a one-piece control element.  
   
   
       6 . The piece of furniture according to  claim 4 , wherein the control device is constructed such that an operating movement of the operating device has swiveling angle ranges in which an essentially horizontal or an essentially vertical movement of the furniture segment is caused, the first control groove having at least one groove section with a uniform distance to the vertical axis or the second control groove having at least one horizontal groove section.  
   
   
       7 . The piece of furniture according to  claim 6 , wherein the control device is constructed such that an operating movement of the operating device from a swiveling starting position into a swiveling end position causes a movement of the furniture segment with at least three movement phases, in which case a swiveling angle range of the operating movement of the operating device is assigned to each of these movement phases and, in a first swiveling angle range, by the control device, a horizontal movement of the furniture segment into a first direction is caused, in a second swiveling angle range no horizontal movement of the furniture segment is caused, and in a third swiveling angle range a horizontal movement of the furniture segment is caused into a second direction opposite to the first direction.  
   
   
       8 . The piece of furniture according to  claim 7 , wherein the control device is constructed such that no vertical movement of the furniture segment occurs in the first and third swiveling angle range and a vertical movement in the upward direction, caused by the control device, occurs in the second swiveling angle range.  
   
   
       9 . The piece of furniture according to  claim 8 , wherein the control device is constructed such that a lowering of the furniture segment is caused by a swiveling movement of the operating device in a swiveling angle range originating from the swiveling starting position.  
   
   
       10 . The piece of furniture according to  claim 9 , wherein the operating device is constructed to be displaceable radially to the vertical axis.  
   
   
       11 . The piece of furniture according to  claim 10 , wherein the supporting device has at least one recess adapted to the operating device, and the operating device is constructed to be slidable into this recess in a swiveling end position or a swiveling starting position.  
   
   
       12 . The piece of furniture according to  claim 11 , wherein two horizontally movable furniture segments are table leaves, which are operatively connected with the operating device by the control device, the control device being constructed for the symmetrical movement of both furniture segments in reaction to the swiveling movement of the operating device.  
   
   
       13 . The piece of furniture according to  claim 12 , wherein the control device is constructed such that, in the swiveling starting position of the operating device, the movable furniture segment is arranged completely under a horizontally stationary furniture segment of the piece of furniture, and in the swiveling end position of the operating device the movable furniture segment is arranged at least partially not under the horizontally stationary furniture segment.  
   
   
       14 . The piece of furniture according to  claim 13 , wherein the control device is constructed such that, in the swiveling end position, an upward pointing surface of the movable furniture segment is arranged to be in an alignment with an upward pointing surface of the horizontally stationary furniture segment.  
   
   
       15 . The piece of furniture according to  claim 14 , wherein the control device is constructed for the horizontal movement of a vertically stationary and for the vertical movement of a horizontally stationary furniture segment, in the swiveling end position, the horizontally stationary furniture segment being lowered to the level of the horizontally movable furniture segment.  
   
   
       16 . The piece of furniture according to  claim 15 , wherein the supporting device has a supporting column, which, at least in sections, has an outside diameter adapted to an inside diameter of the cylinder sleeve.
