  • This invention relates to a cooling device wherein the user can easily open the door.
  • Opening the door can be hard in a cooling device, preferably in a refrigerator, due to the vacuum effect created by pressure difference and/or the magnetic forces of gaskets on the door. This situation can be a problem especially when both hands of user are full when trying to open the door of the cooling device.

  • the arm group (9) comprises an arm (7) which assures the door (2) to be released by the pusher (14) from the grip of the gasket (16) and to stay ajar and not closing again, an arm shaft (24) which provides pivotal movement of the arm (7) around it, and attaches it to the body (3), an arm spring (25) which ensures arm (7) not to open more than the angle (A) preset by the manufacturer while it pivotally turns around the arm shaft (24), and in smaller angles than the said angle (A), pushing the arm (7) and the door (2) which touches the arm (7) to reach the angle (A) preset by the manufacturer with a force less than the magnetic attraction force of the gasket (16), an arm wheel (23) on the edge of the arm (7), contacting the door (2) by moving on inner bottom surface of door (2), facilitating the door (2) to be pushed without damaging the surface when arm (7) moves due to arm spring (25) and prevents closing itself and an arm group cover (28) maintaining the arrangement and protection thereof .
  • a foot lever onto which force can be applied by touching its surface, is used as a force applier (8)
  • a shaft that lies parallel to the force applier (8) along the length of the force applier (8) is used as a force transmitter (6)
  • a pin is used as a pusher (14) retained on the force transmitter (6) to transmit the motion of the force transmitter (6) to the door (2) without restraining movement of the door (2) and with a shape and position so as to be unaffected by the forces acting upon itself.
  • a force transmitter (6) with a quadrilateral cross-section is used which can transmit the force applied on it without being displaced from its retained location due to its cross-sectional structure.
  • the cooling device (1) comprises a force applier (8) with dimensions that enables it to cover almost whole of one of the edge of the body (3) or the door (2).
  • the cooling device (1) comprises a force applier (8) on its body (3) or on the front bottom edge of the door (2) which is smaller than the edge length of the body (3) or the door (2) or longer than the width of a hand or foot, for example 10 cm.
  • the opening mechanism (4) is located at the front bottom part of the door (2) or the body (3) and the force applier (8) enables the opening of the door (2) by pushing by the foot.
  • the opening mechanism (4) is located in the middle or upper part of the door (2) or the body (3) and the force applier (8) enables the opening of the door (2) by pushing by the hand.
  • the user depresses the foot lever; the force applier (8) moves in the direction of foot pressure and herewith rotates the force transmitter (6), which is attached to it.
  • the moving force transmitter (6) starts to rotate the pusher (14), which is attached to the force transmitter (6) inside the force transmitting retainer (12).
  • the pusher (14) pin rotates, it pushes the door support (1 1), which is just opposite of the pusher (14) pin and fixed on the door (2) and con- sequently the door (2), which was stuck to the body (3) with magnetic force created by the gasket (16).
  • the pusher (14) rotates and exerts a thrust on the door support (11) and enables the opening of the door (2).
  • the door (2) may turn back to the initial closed position due to magnetic field effect created by the gasket (16).
  • the arm (7) activated by the arm spring (25) enforces the door (2) to stay open and brings the door (2) to a position set by producer which is beyond the range of the magnetic effect of the gasket (16) at this stage.
  • the arm (7) stays at the latest opened position but since the pusher spring (15) attached to the pusher (14) is stretched; it brings the pusher (14) to its initial position again.
  • the users can press on any point by foot on the force applier (8) positioned preferably almost all along the bottom edge of the cooling device (1) in one piece and by means of a force transmitter (6) preferably aligned parallel to the force applier (8) enabling the force transmitter (6) to trigger the pusher (14) with an almost equal and a small force and thus the pusher (14) enables the opening of the door (2) by pushing with ease.
  • the user can open the door (2) by only pressing on the preferably pedal shaped force applier (8) from the location where the force applier (8) is assembled and cannot access the force applier (8) from any other place.
  • the opening mechanism (4) facilitates ease of production and assembling and provides visual integrity of the cooling device (1).
