  • the door plate comprises more than one cut-out
  • cut-outs is greater than the number of the locking detents.
  • the door plate furthermore comprises two front edge bent portions which are formed by bending the upper and the lower edges of the front wall of the door plate at least partially inwards to bring them to horizontal position and which provide the fixing of the upper and the lower caps without forming protrusions and four side edge bent portions which are formed by bending the upper and the lower edges of the side walls of the door plate inwards to bring them to horizontal position.
  • the cap comprises a front support extension in L-form which is integrated onto the inner part of the front edge of the door plate which seats onto the front wall and which provides the fixing of the cap to the door plate by grasping the front edge bent portion and two side support extensions in L-form which are integrated onto the inner parts of the side edges which seat onto the side walls and which provide the fixing of the cap to the door plate by grasping the side edge bent portion.
  • the front support extension and the side support extensions provide the fixing of the caps mounted to the upper and the lower ends of the door plate without forming protrusions on the front wall and the side walls and prevent the caps from detaching from the door plate due to the
  • the expanding of the side walls to right and left due to the polyurethane pressure is provided by the locking detents hidden at the rear wall side of the refrigerator door and which has high strength. Furthermore, the upper and the lower caps are fixed to the front wall and the side walls of the door plate without forming protrusions, thus improving esthetic appearance.

  • the cap (3, 103) comprises
  • the side walls (5) of the door plate (2) in U-form are stretched to left and right while the caps (3, 103) are closed onto the upper and lower ends of the door plate (2) and the rear bent portion (6) is pushed into the gap (G) between the support plate (7) on the cap (3, 103) and the holding extension (8).
  • the cap (3, 103) is closed onto the door plate (2), rear bent portions (6) are locked in the gap (G) by the locking detents (9).
  • the locking detents (9) prevent the side walls (5) to which the rear bent portions (6) are connected from expanding to right and left after the polyurethane injection process by increasing the strength of the cap (3, 103)-door plate (2) connection.
  • the locking detents (9) are in trapezoid or sawtooth form inclined at the opposite direction to the opening direction of the side walls (5) and are arranged in series at the horizontal direction in the gap (G).
  • the door plate (2) comprises more than one cut-out (10) arranged in series at the horizontal direction, which are disposed in the portion of the rear bent portion (6) which is in the gap (G), which enables the ends of the locking detents (9) to pass through the rear bent portion (6) to be locked ( Figure 5, Figure 6, Figure 7).
  • detents (9) in sawtooth or trapezoid form lodge into the cut-outs (10) on the rear bent portion (6) and provide the rear bent portion (6) to be locked such as not to detach from the gap (G).
