Definitions

  • the invention relates to a door lock for household appliances or the like.
  • a striker and a locking member which can alternately be connected to a housing part or a door and engage in one another in a closed position.
  • the striker is a part stamped out of sheet metal and can be connected to a housing part via a screw connection.
  • the use of such a locking bracket is complex to manufacture and assemble.
  • the assembly effort can be further increased in that manufacturing-related tolerances between the door and the housing part must be compensated for manually by changing the shape of the striker. This may be necessary to ensure that when the locking position is reached, the locking member and the locking bracket engage each other.
  • the invention has for its object to provide a door lock of the type mentioned so that it is easy to manufacture and assemble.
  • the striker can be connected to the housing part or the door via a plug connection, connections for a screw connection need not be provided. Manufacture and assembly of the striker are thus simplified. Cooperation with the locking member can be made possible with reduced or essentially no adjustment effort by a correspondingly elastic design of the locking bracket.
  • the fastening section is pivotally supported by the plug connection and / or the plug connection is assigned a latching connection between the fastening section and the housing part or door.
  • the plug connection is preferably designed to be pivotable in the direction in which manufacturing tolerances can have the greatest impact.
  • the pivoting mobility can be made possible in a known manner, for example by regions of the plug connection which are designed to be resilient in the predeterminable direction or in the manner of ball joints. Through such areas leading to frictional or positive connections, the striker can also be fixed in its longitudinal direction.
  • the position of the built-in striker can be predetermined via the snap-in connection.
  • a plurality of means, arranged in a row in this direction, can be provided on the fastening section for the production of snap-in connections.
  • the plug-in connection has a first and spaced-apart second bearing, each of which is designed in the manner of a transverse bearing and at least one of the bearings has an enlarged area for pivoting mobility of the fastening section essentially perpendicular to its longitudinal axis.
  • the enlarged area can be configured, for example, in the form of an elongated hole, in order to enable the fastening section to be displaced in a predeterminable direction.
  • a sufficiently large swiveling movement of the fastening section can be easily specified via the distance between the two bearings and the length of the enlarged area.
  • the fastening section can be pretensioned with respect to at least one of the bearings by its shape and / or spring elements that can be connected to it.
  • the striker can be brought into a favorable position before the adjustment.
  • a spring element can be connected to the fastening section at an area facing away from the locking member.
  • the fastening section can also be shaped in such a way that it is pretensioned on both bearings after the plug connection has been made.
  • the prestressing can also generate normal forces leading to frictional forces between the fastening section and the bearings. This frictional force ensures that the striker essentially maintains its automatically adjusted position for further use of the door lock after the first contact with the locking member.
  • first and / or second bearing has a through opening in a wall of the housing part or the door.
  • the bearing or bearings can thus be manufactured in a particularly simple manner.
  • the fastening section for a snap-in connection has at least one receptacle for a region of the wall delimiting a through opening.
  • receptacles can be produced simply as groove-shaped recesses or as approaches which are adjacent at a distance and can be produced, for example, by notches, to form groove-shaped spaces.
  • latching connections are of different lengths of the fastening section can be produced. This provides a simple way of adjusting the length over which the striker protrudes from the plug connection to the locking member.
  • the striker is essentially U-shaped, a fastening section for a plug connection being formed on each leg.
  • the connecting piece between the two legs can be designed, without additional effort, as a holding element for holding a locking member during the closed position.
  • twisting of the striker, in an axis parallel to its longitudinal axis, is easily and securely prevented by fastening it via two plug connections.
  • the fastening sections can be preloaded relative to at least one bearing by their mutual position arrangement.
  • the easy-to-apply pretension remains essentially unchanged even after the striker has been adjusted; the adjusted position is thus safely maintained during the subsequent use of the door lock.
  • a striker with a holding element for a locking member or a hook for engaging in a locking member, which has one or more fastening sections according to one or more of the features mentioned above.
  • a striker is particularly easy to produce with predeterminable properties, for generating a pretension and for producing snap-in connections.
  • a first exemplary embodiment of a door lock according to the invention has a locking bracket, designated overall by 1 in FIG. 1, which cooperates with a locking member 2 in a closed position.
  • the locking member 2 is held in a closed position until it is released from the striker 1 via an actuating device (not shown) in order to open the door lock.
  • the striker 1 is connected according to the invention via a pivotable plug connection to a housing part 3 of a household appliance, not shown, such as a dishwasher, a washing machine or the like.
  • the plug connection has a first bearing 4 and a second bearing 5 arranged at a distance therefrom.
  • Each bearing 4, 5 is designed in the manner of a transverse bearing and in a vertical wall 6 or 7 of the housing partly arranged 3.
  • the bearings 4, 5 can, for example, be punched into walls 6, 7 consisting of sheet metal; the contact surfaces of the bearings 4, 5 can be enlarged in a manner not shown, for example by bent sections of the walls 6, 7.
  • the striker 1 has a fastening section 8 which is guided through the two bearings 4, 5.
  • the fastening portion 8 connects in the direction of the locking member 2 via an offset 10, an annular region 9 with a holding element 9 'for the locking member 2.
  • the closing bracket 1, which has the fastening section 8, the annular region 9 and the offset 10 has a circular cross section and can be produced in one piece, for example as a molded plastic part or as a bent wire part.
  • the first bearing 4 has a circular through opening adapted to receive the fastening section 8; it thus enables a pivoting or tilting movement of the fastening section 8 in the manner of a cutting edge bearing.
  • the bearing has 5 shows an area 11 enlarged in the form of a slot in the vertical direction. The enlarged area 11 extends essentially in the direction in which the striker 1 is to be pivotable to compensate for possible manufacturing deviations.
  • the fastening section 8 has receptacles 12, 13 for the bearing 5 delimiting parts of the wall 7.
  • receptacles 12, 13 are formed as mutually opposite, vertically running, groove-shaped recesses; this prevents the locking bracket 1 from rotating after it has snapped into place.
  • Fig. 1 a snap connection between edge regions of the wall 7 and the receptacle 12 is shown.
  • An adjustment of the striker 1 in the longitudinal direction relative to the locking member 2 is possible in that a latching connection can also be made between the receptacle 13 and edge regions of the wall 7. Due to the adjustment possibility, a position arrangement of the striker 1 relative to the locking member 2 is possible, in which both parts can interlock securely for closing.
  • receptacles (not shown) which can be formed next to one another in the longitudinal direction, a fine-stage adjustment possibility for the locking bracket 1 in the longitudinal direction can be made possible.
  • receptacles can be formed in a manner not shown, for example also by gaps between projections formed on the fastening section 8.
  • the locking member 2 can be pivotally connected to a door 15 in a known manner.
  • the door 15 can be pivoted open in the direction of arrow 16.
  • a locking lug 17 of the locking member 2 engages the holding element 9 '.
  • the locking member 2 is drawn in a position before closing or after opening the door lock.
  • the position of the striker 1 must be aligned relative to that of the locking member 2.
  • the pivoting design of the plug connection enables automatic adjustment of the striker 1. Any vertical manufacturing deviations between the housing part 3 and door 15 can be compensated for by the first and second bearings 4, 5 via the pivotable mounting of the fastening section 8.
  • the holding element 9 ' is moved by the locking member 2 in a position enabling a door lock.
  • the pivoting direction and the limit positions indicated by dash-dotted lines 23, 23 'and thus also the entire pivoting range of the striker 1 can be predetermined.
  • the pretension of the striker 1 and thus also its setting position after inserting the striker 1 into the bearings 4, 5 and before an adjustment via the locking member 2, which takes place during a first closing operation can be predetermined.
  • the second exemplary embodiment shown in FIG. 2 differs from the first exemplary embodiment essentially only in that the closing bracket, designated as a whole by 30, is U-shaped. It has two fastening sections 38, 38 ', one of which is formed on one leg. Unchanged components relating to the housing part 3 are identified by the same reference numerals.
  • both fastening sections 38, 38 ' are guided through first bearings 34, 34' and spaced-apart second bearings 35, 35 'to form plug connections.
  • the first and second bearings 34, 34 'and 35, 35' are also in the form of through openings in vertical walls 6, 7 of the housing part 3.
  • the second bearings 35, 35 'enlarged oblong areas 41, 41' For a pivoting movement of the striker 30 in a substantially vertical direction 20, the second bearings 35, 35 'enlarged oblong areas 41, 41'.
  • the fastening sections 38, 38 'receptacles 42, 43, 44 and 42', 43 ', 44', each formed on opposite sides of the fastening sections 38, 38 ' are.
  • the first bearings 34, 34 ' have elongated holes 55, 55' in the horizontal direction. A pivoting movement of the striker 30 is thus also possible in this direction.
  • a prestress can be produced after the production of plug connections, in each case with respect to a second bearing 35, 35'.
  • the fastening sections 38, 38 'with their receptacles 42, 42' are pretensioned in areas of the wall 7; the fastening sections 38, 38 'are arranged so that the distance between them in the rest position before installation is greater than after establishing the plug connection.
  • the way in which a preload is applied is not limited to the example given;
  • the mutually facing sides of the fastening sections 38, 38 ', with a correspondingly changed arrangement of receptacles, are pretensioned on mutually facing sides of the second bearing 45, 45'.
  • the bias prevents unintentional loosening of the locking connections between the fastening sections 38, 38 'and the wall 7.
  • Generable by the bias normal forces continue to cause frictional forces between the mounting portions 38, 38 'and corresponding contact areas of the bearings 35, 35', so that after an automatic adjustment of the striker 30, in the Wei described for the first embodiment se, the position of the striker 30 remains essentially unchanged for further use of the door lock.
  • a holding element 39 to be gripped behind in the closed position of the door lock by a latching lug of a locking element is given, due to the U-shaped design of the locking bracket 30, by the intermediate piece connecting the two legs.
  • the holding element 39 in the present case - like the holding element 9 'according to the first embodiment - by means of bends 40, 40' to the fastening sections 38, 38 '.
