Definitions
- the present invention relates generally to a lock for locking systems, in particular door locks and here in particular door locks for refrigerators, preferably refrigerators for leisure vehicles, such as e.g. Caravans, motorhomes, etc. are used.
- Door locking systems or more generally locking systems for all possible types of locks are already known.
- such locking systems mostly only have one locking position, with which — in the case of refrigerator doors — either the refrigerator door is kept closed or not.
- This is however, unsatisfactory for refrigerators, since it is desirable for refrigerators that are not used for a long time to leave a gap open to ventilate the refrigerator to prevent mold and odors.
- This is particularly desirable for refrigerators for caravan vehicles and the like, since these refrigerators are often not operated for a long time. In this case, however, the refrigerator door must then be left in an unsecured state, since the locking systems only enable locking when the door is completely closed.
- this locking system should be simple to set up and operate and require only a small amount of space.
- the locking system essentially comprises two elements. These two elements are attached to the two parts of a locking system to be locked together, e.g. the door and the associated stop. While one element is preferably largely rigid e.g. is attached to the housing of a refrigerator, the other element is preferably designed as a lever element and is pivotable, for example arranged on the door of a refrigerator. Either on the lever element or on the rigid element there is preferably a latching hook, e.g. provided in the form of a bolt which engage in a complementary locking element on the corresponding counterpart of the locking mechanism, e.g. a slot-shaped recess. In order to enable a plurality of locking positions of the locking mechanism, a plurality of latching hooks and / or latching elements are provided which define a plurality of locking positions when they intervene.
- a plurality of latching hooks and / or latching elements are provided which define a plurality of locking positions when they intervene.
- the rigid element or the lever element are preferably designed essentially as flat metal plates, which leads to a low overall height.
- the latching hooks and elements are preferably designed as bolts and slots designed to complement them, so that the bolts can engage in the slots and be released again by moving the lever element.
- FIG. 2 shows the two parts from FIG. 1 in a locking position
- FIG. 3 shows the installation of one of the parts from FIG. 1 in a refrigerator
- Fig. 4 shows the interaction of the two parts from Fig. 1 in a door lock on one
- Refrigerator door shows the further installation of the door lock according to the previous figures in a refrigerator door.
- Fig. 6 the door lock acc. 5 in a further locking position in which the refrigerator door is opened a gap and in FIG. 7 the locking position from FIG. 6 in a side view.
- Fig. 1 shows the essential elements of the door lock according to the invention, namely the metal plate 1 and the lever 2.
- these two parts are in each case opposite to the partners of a door lock, namely the door and stop base or very generally on the movable locking element and the associated stop, for example Window sash and window frame, etc., attached.
- the door lock is provided for refrigerators and here in particular for refrigerators in recreational vehicles, such as caravans, motorhomes, etc.
- the metal plate 1 is preferably arranged on the housing of the refrigerator, while the lever 2 is provided on the refrigerator door.
- the metal plate 1 has for its attachment to the housing of a refrigerator, for example for the passage of screws or the like; Bores 5, three holes being provided in the exemplary embodiment shown, which describe the corner points of a triangle. Furthermore, the metal plate 1 has a bolt 3 which has a head or collar 4 at its end opposite the metal plate 1. The bolt 3 can be fastened to the metal plate 1 in a conventional manner, in particular by welding or riveting.
- the lever 2 has a rotary opening 8 with which the lever can be pivotally attached to the door of the refrigerator.
- two slots 6 and 7 are provided, the slot width of which is matched to the diameter of the bolt 3.
- the slots 6 and 7 are slightly curved, the bending of the slots being matched to the position of the rotary opening 8 such that the bolt 3, when it is received in the end region of the slots 6 or 7, is subjected to a tensile load along the longitudinal direction of the lever 2 is held in the slots because the arcuate curvature of the slots 6 and 7 counteracts movement along the slots 6 or 7.
- the diameter of the collar 4 at the end of the bolt 3 is such that the bolt 3 cannot leave the slots 6 or 7 in the longitudinal direction of the bolt, that is to say perpendicular to the lever 2.
- Fig. 2 shows schematically the interaction of the metal plate 1 and the lever 2 in a locking position.
- the bolt 3 is received in the end region of the slot 7.
- the lever 2 is pivoted about the rotary opening 8 in such a way that the bolt 3 leaves the slot 7.
- the door to which the lever 2 is usually attached is thus free relative to the stop element, for example the housing of a refrigerator, on which the metal plate 1 is normally arranged, so that the door can be opened.
- a slide bushing 9 or a bearing element is preferably inserted in the rotary opening.
- FIG. 3 shows the arrangement of the metal plate 1 (part 1) on the housing of a refrigerator for a caravan.
- the metal plate 1 is arranged between the switch panel 11 of the housing and the cooling space 10 of the housing, the bolt 3 projecting downward with its head or collar 4.
- Reference number 12 denotes the opening of the cooling space 10, which is closed with the door 13.
- FIG. 4 shows the arrangement of the lever 2 (part 2) on the door 13, with which the opening 12 of the cooling space 10 from FIG. 3 can be closed.
- a bolt-like actuating member 14 is provided on the top of the plate-shaped lever, with which the lever 2 can be pivoted about the rotary opening 8 on the refrigerator door 13.
- the refrigerator door 13 can be locked via the metal plate 1 and the lever 2 with the cooling space 10 or the housing of the refrigerator, in which the lever 2 is pivoted with the actuating member 14 in such a way that the bolt 3 engages in one of the slots 6 or 7.
- the lever 2 only has to be pivoted by actuating the actuating member 14, specifically to the left in the exemplary embodiment shown, and the slots 6 or 7 release the bolt 3 and thus the door 13 by pivoting to the right.
- the lever 2 can be arranged under a cover 15, the rotary opening 8 also serving as a location for the attachment of the fastening means for the cover 15.
- a screw for fastening the cover to the door 13 is simply arranged through the rotary opening 8.
- the cover 15 has a cutout 16 for the actuator 14.
- a corresponding recess 17 is also provided for the engagement of the bolt 3 (see FIG. 6).
- the locking position shown in Fig. 5 is the position at which the door 13 is fully closed, i.e. the bolt 3 engages in the slot 7 of the lever 2 here.
- 6 and 7 show the locking position, in which the refrigerator door 13 is not completely closed, the so-called parking position, in which the bolt 3 of the metal plate 1 engages in the slot 6 of the lever 2, so that the door 13 a gap is open.
- This is particularly advantageous for refrigerators that are not operated for a long time, as is the case in particular with caravan vehicles.
- the gap-wise opening of the refrigerator prevents the formation of mold and odors in the device and thus serves to increase the quality of use.
- the cooling cabinet is held in a defined, secured position, so that damage and injuries caused by uncontrolled door movements are avoided.
- the door lock according to the invention also has the advantages that it can be installed on a refrigerator in a space-saving manner and, due to its simple construction, does not require excessive effort.
- the locking system according to the invention is arranged on the stop side of the refrigerator door, that is to say on the side opposite the side on which the door with the hinges is pivotably mounted. It goes without saying that the locking system can also be arranged at any other suitable location, that is to say in particular on the entire upper side of the door, provided that the locking device is at a distance from the axis of rotation or pivoting of the door, so that the locking means that or pivoting movement of the door can be prevented.
- the locking arrangement is, however, provided in the center of the door on the top and bottom.
- This particular location for fastening the locking system has the decisive advantage that the locking system does not have to be changed if the door stop is to be changed, for example from one right to one Left stop must be changed.
- the locking system according to the invention can develop its effect in the same way without modification.
