Definitions

  • the invention relates to a locking device, in particular for the door of a dishwasher, with the features of the preamble of claim 1.
  • Locking devices of the type mentioned with a preferably housing-side locking block or locking bracket and with a preferably door-side locking device are known, wherein a pivotally mounted latch and a locking and control element articulated on the latch cooperate in the manner of a toggle lever device and from a stable end position in the "open" position "can be moved into another stable end position or closed position via a dead center position.
  • These known locking devices can also each have a handle which is pivotally arranged on the door and serves as an opening aid, and finally at least one electrical switch is also provided in each case and is controlled by the locking device or by the handle.
  • the door opening in the dishwasher is relatively large and the same applies to the length of the seal which is effective between the door and between the dishwasher housing and which is arranged in the region of the outer contour of the door and dishwasher housing. Because of the length of this seal, high forces have to be applied to close the door and also high locking forces must be effective when the door is closed, with the result that sometimes very high forces prevail on the individual components of the locking device when the door is closed. Since the doors in modern dishwashers can usually be closed with the whole hand, it is unproblematic to apply the closing forces required to close the door properly and to create the seal. However, it is then problematic to generate the opening forces required to open the closing device. These opening forces must be able to overcome the holding forces of the closing device, for which purpose the pull handles known in the past have been used.
  • the invention is therefore based on the object of designing a simply constructed locking device of the type of interest here for a dishwasher in such a way that the door is held securely with a large locking force and correspondingly the seal and that only a small force is required to open the door .
  • the invention provides with the features of the characterizing part of claim 1 that the pivotally mounted case and the closure and control element are also connected to one another with the aid of a common guide element and that the closure and control element are displaceably and pivotally mounted on the housing side is.
  • the force and lever ratios between the case forming a toggle lever device and the associated closure and control element acting in the manner of a spring strut can be changed when opening with a pivotably mounted handle.
  • the closure and control element is moved in the direction of the dead center position formed by the two housing-side, fixed bearing journals for the latch and for the closure and control element, so that a more favorable opening force is used instead of the high locking force sets.
  • the guide element is preferably arcuate and assigned to the trap, and preferably an elongated hole, while a further elongated hole is provided for a bearing journal fixed in the housing in the closure and control element for its pivotable and displaceable mounting.
  • a locking device 3, in particular intended for the door 1 of a dishwasher 2, comprises a locking block or striker 4, preferably arranged in the dishwasher housing, and a locking device 5, preferably on the door side.
  • the locking device 5 includes a latch 8 and pivotally mounted on a carrier or lock housing 6 with the aid of a bearing pin 7 a locking and control element 9 articulated on the latch 8, which together with the latch 8 forms a locking device in the manner of a toggle lever device 5 '.
  • the bearing pin 7 on the latch 8 engages in an elongated hole 10 of the carrier or the lock housing 6.
  • a pivot bearing pin 11 connects the Trap 8 with the closure and control element 9, which is movably or, according to the exemplary embodiment, pivotably and displaceably mounted on the carrier or lock housing side with the aid of a bearing pin 12 and an elongated hole 13.
  • the bearing point of the closure and control element 9 which is effective on the lock housing side can therefore be changed.
  • the locking and control element 9 is, according to the exemplary embodiment, a double-armed lever 9 'in the manner of a strut with a spring 14, the ends of which are arranged between the bearing pins 11 and 12 and the one arm 15 articulated on the latch 8 of the double-armed lever 9 'surrounds.
  • the spring 14 is a toggle lever spring and holds the locking device 5 or the latch 8 in the respective end positions “open” according to FIG. 3 or “closed” according to FIG. 1 on both sides of the dead center position TL indicated by dash-dotted lines in FIG. 1.
  • the second arm 16 of the double-armed lever 9 extends in a direction facing away from the pivot bearing journal 11.
  • the effective length of the two arms 15 and 16, based on their bearing on the journal 12, can be changed due to the elongated hole 13, with the result that forces acting on the two arms 15 and 16 can also be changed as a result of variable lever ratios.
  • the articulation of the swivel-mounted case 8 on the displaceable and swivel-mounted locking and control element 9 is carried out not only with the help of the swivel bearing pin 11, but due to its function primarily with the aid of a common guide element 17.
  • This guide element 17 is arcuate and, according to the exemplary embodiment, an arcuate elongated hole 17 '.
  • the arc-shaped elongated hole 17 ' is arranged in the trap 8 and faces the closure and control element 9 with the center of its radius or concave.
  • the guide element 17 or the arcuate elongated hole 17 ' is arranged such that its ends 18, 19 and the bearing pin 7 of the latch 8 form a triangle on the side facing away from the fork mouth 20.
  • the closure and control element 9 not only consists of the double-armed lever 9 'with the two arms 15 and 16, which are arranged stretched relative to one another, but has an L-shaped basic shape and also comprises a side arm 21 projecting from the lower arm 16.
  • at least one pressure piece 22 is arranged on the side arm 21, for example in the form of a lateral projection 22, on which a driver 23 engages a handle 25 which is pivotally mounted in the door 1 about an axis 24.
  • the driver 23 rests with an inclined surface 26 on the pressure piece 22 on its side facing the journal 12, as shown in FIG. 1.
  • the power transmission from the driver 23 to the pressure piece 22 takes place normally, i.e. in a direction tangential to its axis 24 when the handle is raised when opening from the position shown in FIG. 1.
  • a switching arm 27 for controlling an electrical switch 28 is preferably also arranged on the closure and control element 9.
  • the latch 8 When the door 1 is closed or closed from the 'open' position according to FIG. 3, the latch 8 is gripped by the striker 4 entering the fork jaw 20 and pivoted about the bearing journal 7 or clockwise.
  • the closure and control element 9 connected to the trap 8 via the guide element 17 or via the arc-shaped elongated hole 17 'and the pivot bearing pin 11 is carried along by the end 19 (FIG. 1) of the elongated hole 17' until that of the Bearing pin 7 and the bearing pin 12 formed dead center position TL is exceeded.
  • the spring 14 is tensioned here.
  • the pivot bearing pin 11 slides in the arcuate elongated hole 17 'to its other end 19 and on the one hand causes a large trailing path of the latch 8 and on the other hand a high tractive force as a result of the effective lever arm which increases through the elongated hole 17' the trap 8 and the thereby favorable force curve of the relaxing spring 14. This is achieved by the position of the elongated hole 17 ', which not only forms a triangle with the journal 7, but whose end 18 is further away from the journal 7 than its other Late 19th
  • the opening process from the position shown in FIG. 1 is initiated by lifting the handle 25.
  • the handle 25 engages with two surfaces or inclined surfaces 26 one behind the other in FIG. 1 on pin-like projections 22 ′ of the closure and control element 9 and pulls and pivots it in the direction of the dead center position TL.
  • the relative movement of the striker 4 causes the latch 8 to pivot in the opening direction, and the double-armed lever 9 'of the locking and control element 9 acts together with the spring 14 a stable open position of the locking device 3, since now the latch 8 and the locking and control element 9 are on the other side of the dead center position TL.
  • the closing device 1 can also be torn over or pushed open from the interior.
