Definitions

  • the present invention relates to an innovative door deceleration mechanism which prevents the doors from closing too fast in built-in fridges and similar household appliances, and which elongates their operating life.
  • the doors placed on the volume to be used especially in built-in household appliances and similar devices differ according to their opening directions.
  • the doors in built-in household appliances perform upward or horizontal opening movement.
  • the door completes the closing movement by performing rotary movement centered around its edge on which it is connected with the pushing force applied by the user or the weight force of the door.
  • the door hits on the body rapidly in closing movements realized with weight force of the door or the force of the user.
  • the door can be deformed upon the door hitting harshly on the body, and there can be serious injuries if the limb of the user is left under the door.
  • heat transfer may increase between the outer environment and inside the inner volume of the appliance as a result of opening the door after it is closed, and this situation negatively affects the operation of the appliance.
  • a force should be applied on the appliance body for keeping the door closed after it is closed.
  • the United States patent document no. US2010101052 discloses a hinge mechanism with multiple connections.
  • the inventive multiple connection hinge comprises a fixing member, and a rotatable door shaft bearing is attached movably relative to the fixing member.
  • a spring placed between the fixing member and the door shaft bearing applies pre-tension to the door shaft bearing while the door is in closed position.
  • the inventive multiple connection hinge mechanism can especially be applied to the fridge doors in order to prevent hitting.
  • Patent document no. DE29918559 U1 discloses a wide-angle hinge, in particular for furniture, wherein a body-side hinge part side and a wing fixed to one another by a plurality of pivot tabs, is accessible to an angle of substantially greater than 90 °, wherein the usable angle is reduced by a spacer, the spacer element is U-shaped profile in cross section and that the lateral legs of the U-shaped spacer with parallel or substantially parallel to the central web slots extending are provided and that the spacer in its width to a serial link is pushed, in the inserted state with the wider area the articulated lever in the longitudinal slot of the lateral legs of the spacer engages.
  • the objective of the present invention is to provide an innovative and long-lasting door deceleration mechanism which enables the doors of the household appliances such as built-in fridge and like to be closed by decelerating.
  • the objective of the present invention is to provide an innovative door deceleration mechanism which enables the doors of the household appliances such as built-in fridge and like to be closed by decelerating without using spring member.
  • the objective of the present invention is to provide an innovative door deceleration mechanism wherein damping mechanism is used for closing doors of the household appliances such as built-in fridge and like by decelerating.
  • Another objective of the present invention is to provide an innovative door deceleration mechanism which comprises several precautions against damages that can occur due to internal and external forces and which provides long operating time.
  • a door deceleration mechanism (1) which prevents the doors especially in built-in fridges and the like from closing too fast, essentially comprises
  • the inventive door deceleration mechanism (1) is in form of five arms which enable the loads originating from door weight and the internal parts of the hinge to be distributed and a slow closing movement to be realized.
  • the distribution of the loads increases the static and dynamic strength of the mechanism and also increases its operating life.
  • the door deceleration mechanism (1) is comprised of an upper bracket (3) fixed on the door, a fixed bracket (2) fixed on the body on which the door will be closed, a first arm (4), a second arm (5) and a third arm (6) enabling the door to realize opening and closing movements by making folding movement, a guide arm (7) preventing the door from closing too fast, and a damping arm (8).
  • the fixed bracket (2) is provided fixed on the body on which the door will be closed.
  • the five arm mechanisms are provided between the fixed bracket (2) and the upper bracket (3).
  • the first arm (4) provided on the fixed bracket (2) makes rotary movement centered around the connection point of the fixed bracket (2).
  • the second arm (5) and the third arm (6) provided between the first arm (4) and the upper bracket (3) realize a folding movement together with the first arm (4) in opening and closing movement of the door.
  • There is a guide arm (7) which enables the first arm (4), second arm (5) and the third arm (6) to move in desired closing and opening directions in opening and closing movements of the door.
  • the guide arm (7) makes rotary movement on the fixed bracket (2) to which it is connected in opening movement of the door, and enables the third arm (6) to which it is connected and thus the first arm (4) and the second arm (5) to move in a certain direction.
  • the damping arm (8) is attached on the third arm (6) from one side such that it can rotate freely, and it is attached on the second arm (5) from the other side.
  • the damping arm (8) has a slot (81) in form of a channel the connection of which to the second arm (5) passes onto a pin (51) and which can move on the fixed pin (51). It transfers the loads that come during closing of the door on to the body on which the door closes through the fixed bracket (2).
  • the damping arm (8) makes rotary motion on the third arm (6) to which it is connected, and the slot (81) provided on its other end moves on the fixed pin (51).
  • the movement of the fixed pin (51) inside the slot (81) continues until closing movement comes to the position where it is wanted to be slowed down.
  • the pin (51) contacts around the slot (81) when the closing movement comes to the level where it is desired to be slowed down, and the slot (81) is prevented from moving in direction of the fixed pin (51).
  • the damping arm (8) realizes a flexing movement.
  • the damping arm (8) provided between the second arm (5) and the third arm (6) slows down the movement of the second arm (5) and the third arm (6), and enables the door to complete its closing movement slowly.
  • the guide arm (7) and the damping arm (8) are manufactured from a flexible material.
  • the guide arm (7) and the damping arm (8) become more suitable for absorbing the loads coming thereon thanks to being manufactured from a flexible material, they return to initial positions and forms upon lifting the loads.
  • the guide arm (7) and the damping arm (8) are manufactured from a plastic material.
  • damping system (9) which is activated during closing movement of the door.
  • the said damping system (9) essentially comprises
  • the damping system (9) essentially transfers the force it receives from the guide arm (7) on the force damper (92) with a rotary movement depending on the cam form of the bump (71), and thus decelerates the door.
  • the guide arm (7) starts to make rotary motion centered around the fixed bracket (2).
  • the bump (71) provided on the guide arm (7) contacts the first extension (911) provided on the connection piece (91), and transfers the closing force of the door to the first extension (911).
  • the force coming on the first extension drives the connection piece (91) for rotating around its own axis, and it is transferred to the force damper (92) through the second extension (912) provided on the connection piece (91).
  • the loads generated due to inertial moment of the door are enabled to be transferred to the damping system (9) first by the guide arm (7) in a certain angular position and depending on the cam form provided on top of the bump (71), and then to the fixed bracket (2) by the damping system (9).
  • the guide arm (7) transfers the loads coming during closing of the door to the fixed bracket (2) through the damping system (9) depending on the cam form (71). These loads are transferred on the body on which the door is closed by means of the fixed bracket (2).
  • the excessive loads that can occur due to closing the door faster than required are absorbed by the guide arm (7) flexing in opposite direction relative to the cam form (71), and the piston (92) provided on the damping system (9) is prevented from being deformed due to excessive loads.
  • the force damper (92) is a piston. In this way, the forces coming on the connection piece (91) are absorbed with a piston, and the door is enabled to close slowly.
  • the force damper (92) is a spring. In this way, the forces coming on the connection piece (91) are absorbed with a spring, and the door is enabled to close slowly.
  • the guide arm (7) is flexible. In excessive loads that can occur in case the door is closed too fast, the guide arm makes flexing movement in opposite direction of the incoming force and absorbs the force, and thus the force damping (92) piece is prevented from being deformed under excessive loads.
  • damping system (9) is used together with slowing down of the damping arm (8), it is activated in case an excessive load comes on the door in closing direction.
  • the damping system (9) is used instead of spring, and it realizes the slow closing movement of the door all by itself.
  • the guide arm (7) and the damping arm (8) are connected on the third arm (6) such that they will rotate freely on the same shaft. In this way, both guide arm (7) and the damping arm (8) can realize rotary motion centered around a single shaft by means of using a single shaft.
  • damping arm (8) which is connected on the third arm (6) from one side such that it will freely rotate, and which is connected on the second arm (5) from its other end upon the pin (51) passing inside a linear channel shaped slot (81) provided thereon, which slows down the closing movement of the door by means of a rotary movement centered around the third arm (6) during closing movement of the door and a flexing movement after the movement of the slot (81) towards the pin (51) ends, the flexing movement of which continues up to a certain angular position, which transfers force to the second arm (5) and the third arm (6) to which it is connected due to the flexing movement it performs in closed position of the door, and which helps the door to remain in closed position by means of the force it transfers.
  • damping arm (8) which is connected on the third arm (3) from one side such that it can rotate freely and to the second arm (5) by the pin (51) passing inside a linear channel shaped slot (81) provided thereon from the other side, which makes rotary motion centered around the third arm (6) during the opening movement of the door, and which preserves its current form due to the movement of the slot (81) towards the pin (51), and therefore which is not subjected to any elastic-plastic deformation, fatigue during opening movement of the door.
