Door closing connection

Abstract

A door lock for frontally loading a washing machine, a drier or similar devices, which is mounted on the machine front wall, wherein said door lock comprises a stop knob and a locking segment provided with an undercut, the front wall comprises an aperture and a stop opening, the locking segment, in the operating position thereof, is connected by behind to the opposite edges of the aperture and the undercut, and the stop knob is inserted into the stop opening. The peripheral contour of the undercut is at least partially rounded, thereby enabling the locking segment to be rotatable in the aperture.

       11 . An arrangement of a door lock of a front loading door of a laundry appliance including at least one of a washing machine and a dryer and having a front panel, the door lock comprising:
 a stop knob and a locking portion with an undercut, the front panel having an aperture and a stop opening, the locking portion penetrating the aperture in its operating position;   grips opposing edges of the aperture from behind with the undercut and the stop knob fits into the stop opening; and   wherein the undercut has an at least partially rounded peripheral contour enabling a rotation of the locking portion in the aperture.   
   
   
       12 . The arrangement as claimed in  claim 11 , further comprising a single stop knob for fixing an operating position of the door lock. 
   
   
       13 . The arrangement as claimed in  claim 11 , further comprising a square aperture, wherein the largest dimension of the undercut shape defined by the peripheral contour corresponds to the length of a lateral edge of the aperture. 
   
   
       14 . The arrangement as claimed in  claim 13 , further comprising a peripheral contour which is composed of a semicircular arc and the flatter semi-elliptical arc. 
   
   
       15 . The arrangement as claimed in  claim 11 , further comprising a rectangular aperture with longer and shorter lateral edges, wherein the length of the longer lateral edge of the aperture corresponds to the length of at least one lateral edge of the locking portion. 
   
   
       16 . The arrangement as claimed in  claim 11 , wherein the largest dimension of the peripheral contour corresponds to the length of the longer lateral edge of the aperture. 
   
   
       17 . The arrangement as claimed in  claim 11 , further comprising a peripheral contour which, based upon a rectangle with a length corresponding to the length of the shorter lateral edge of the aperture, has instead of two corners opposing curvatures, the radius of which corresponds to half the length of the shorter lateral edge of the aperture. 
   
   
       18 . The arrangement as claimed in  claim 11 , wherein the stop knob is elastically mounted. 
   
   
       19 . The arrangement as claimed in  claim 11 , wherein the stop knob has a cross-section which deviates from the circle cross-section. 
   
   
       20 . A method for assembling a door lock of a front loading door of a laundry appliance having a front panel, the method comprising the acts of:
 inserting the door lock with a locking portion into an aperture on the front panel; and   rotating the door lock into its operating position and locking the door lock in the operating position on the front panel.
