  • the linkage mechanism realized to achieve the aim of the present invention is suitable to be used in ovens, domestic appliances such as refrigerators or furniture such as wardrobes comprising French style side-by-side doors, and is mounted on a horizontal axis on the upper wall or the lower wall of the body of the appliance/item on which it is used, and enables both doors to be opened and closed simultaneously by a user pulling or pushing only one of the doors.
  • the linkage mechanism comprises two link arms connected to the doors, a carriage block to which the rear ends of the link arms are connected, and a rail on which the carriage block moves.
  • the link arm connected to the door being opened or closed transmits its movement by means of the carriage block to the other link arm and therefore to the other door.

  • the linear slide bearing is a bearing bushing made of a material with low friction coefficient such as plastic or bronze.
  • the linkage mechanism comprises bulges provided proximate to the rear end and the front end of the rail, enabling the doors to be sealingly closed and to be halted when the doors are brought to approximately 90 degrees open position.
  • the carriage block is supported by two split bushing halves so as to be able to pass over the bulges on the rail.
  • the busing halves mutually contact the rail surface by means of two compression springs.
  • Figure 1 is a perspective view of an oven and a linkage mechanism with the doors in closed position.

  • the linkage mechanism (1) enables both doors (12) to be opened and closed simultaneously by a user moving only one of the doors (12).
  • the linkage mechanism (1) of the invention comprises - two link arms (2) symmetrically connected by their front ends to the doors (12) so as to be pivotable about the vertical axis, movable parallel to the horizontal plane (14), and extending from both doors (12) by converging to each other towards the rear edge of the horizontal plane (14), - a linear motion guide rail (3) (hereinafter referred to as ‘rail (3)’ in short) fixed on the horizontal plane (14) in parallel to the horizontal plane (14) by means of a front mounting plate (15) and a rear mounting plate (16), - a carriage block (4) to which the rear ends of the link arms (2) are connected so as to be pivotable about the vertical axis, moving on the rail (3) during opening and closing of the doors (12), and - a linear slide bearing (5) provided in the carriage block (4), enabling the carriage block (4) to be movably supported on the rail (3).
  • the link arm (2) connected to the door (12) being opened or closed transmits its movement by means of the carriage block (4) to the other (second) link arm (2) and therefore to the other (second) door (12), thereby enabling both doors (12) to be opened or closed simultaneously.
  • the linear slide bearing (5) significantly reduces the friction forces acting on the linkage mechanism (1). A user can open and close the doors (2) by utilizing very little force, thereby providing ease of use and silent operation.
  • the linkage mechanism (1) comprises a linear slide bearing (5) consisting of a cylindrical rail (3) and a one-piece bearing bushing (6) of hollow cylindrical structure provided in the carriage block (4), made of a material with low friction coefficient, whose inner surface contacts all around the rail (3), enabling the carriage block (4) to slide on the rail (3).
  • the bearing bushing (6) is preferably made of a plastic material, e.g. acetal (POM), Teflon (PTFE) or polyamide (PA), or may be made of bronze or a graphite added material with self-lubricating properties.
  • a plastic material e.g. acetal (POM), Teflon (PTFE) or polyamide (PA), or may be made of bronze or a graphite added material with self-lubricating properties.
  • the linkage mechanism (1) comprises a first bulge (7) provided at the rear portion of the rail (3), enabling temporarily stopping or “halting” the carriage block (4) and therefore the doors (12) connected to the link arms (2) when the doors (12) are being brought to the fully closed position and from the closed position to the open position.
  • the linkage mechanism (1) comprises at least one second bulge (8) provided at the front portion of the rail (3), enabling temporarily stopping the carriage block (4) and therefore the doors (12) connected to the link arms (2) when the doors (12) are being brought to approximately 90 degrees opened position.
  • the first bulge (7) and the second bulge(s) (8) are formed on the cylindrical rail (3) by means of a production method such as forging.

  • the linkage mechanism (1) further comprises two compression springs (10) connected between the bushing halves (9) and the carriage block (4), enabling the bushing halves (9) to mutually apply pressure on the rail (3) surface with a determined force
  • the compression springs (10) enable the carriage block (4) to be supported without gaps at all positions on the rail (3) and with a predetermined pressure force by pushing the bushing halves (9) towards each other.
  • the carriage block (4) moves from front to back on the rail (3) and passes over the first bulge (7) reaching the bulge's inclined portion behind the bulge in the narrowing direction thanks to the linear slide bearing (5) having two bushing halves (9) and the compression springs (10).
  • the inclination of the first bulge (7) in the narrowing direction towards the back forces the carriage block (4) to move towards the back side.
  • the first bulge (7) backs up the closing force applied by the user, enabling the doors (12) to be sealingly closed.
  • the carriage block (4) moves from back to front on the rail (3), passing over the first bulge (7) from back to front.
  • the narrowing portion in front of the first bulge (7) backs up the forwards motion of the carriage block (4).

  • the carriage block (4) is halted by the second bulge (8).
  • the halt enforced by the second bulge (8) at approximately 90 degrees opened position allows the user to check whether there is a unsafe obstacle for the doors (12) to be opened more than 90 degrees.
