Definitions
- the invention relates to a refrigerator with at least one refrigerator, which is equipped with a drawer-like storage compartment, which has at least on its two longitudinal sides lying in the insertion direction, a parallel guide device, which by a rack-like counter-toothing and two at least approximately rigidly coupled to each other, at least largely axially opposing rollers with an external toothing of the same pitch circle diameter is formed, which is able to roll on the counter toothing, with either the counter toothing or the rollers are arranged in a fixed position.
- EP 07 18 574 A1 discloses a refrigeration device with a cooling compartment, which is equipped with storage compartments which can be pulled out like a drawer, the larger of the storage compartments carrying a door for closing the cooling compartment.
- the storage compartment provided with the door is equipped with a parallel guiding device, which is formed by toothed rack-like counter-teeth provided on the side walls of the cooling compartment and external toothed rollers provided on the side walls of the storage compartment that are able to interact with the counter-teeth.
- the measure according to the invention automatically compensates for the inclined position of the storage compartment when it is in the closed position, which can be caused, for example, by an abrupt, eccentric introduction of force on the storage compartment, as a result of which the storage compartment door fitted with a seal always lies tightly against the opening edge of the access opening to the cooling compartment.
- a gap between the seal provided on the storage compartment door and the opening edge of the access opening to the refrigerator compartment is inevitably avoided, so that even if the storage compartment is improperly handled, the intended refrigerator compartment temperature is always reliably ensured when the storage compartment is in the closed position, since the storage compartment after each closing operation is made automatically from its inclined position to a position in which the door provided on the storage compartment runs at least largely parallel to the opening edge of the cooling compartment.
- the means are formed by a tooth gap provided on the counter-toothing, which is arranged on the end portion of the counter-toothing rolled off by the roller at the end of the closing process of the storage compartment.
- the tooth gap is provided on both counter-toothings and that the tooth gaps are followed by a feed area for the rollers with at least approximately continuously increasing tooth height up to the tooth height.
- the counter-toothings are particularly expedient if, according to a next advantageous embodiment of the object of the invention, it is provided that one of the counter-teeth is provided on one of the side walls of the cooling space arranged in the insertion direction of the storage compartment.
- Counter gears arranged in this way can be arranged in a particularly positionally and dimensionally stable manner, for example in the form of a U-shaped guide profile equipped on one of its legs with the counter teeth, which is either placed directly on the side walls or embedded in a recess corresponding to its outer contour in the side walls and there in addition to Increasing the stiffness of the guide profile is supported by the thermal insulation of the refrigerator generated by foaming.
- the counter toothing is provided on one leg of a plastic guide profile with a U-profile cross section, the counter toothing can not only be produced in a particularly simple manner with different tooth pitches and tooth sizes, but can also be replaced particularly cost-effectively in the event of damage.
- the feed from the tooth gap area into the counter-toothing is particularly user-friendly if, according to a next advantageous embodiment of the object of the invention, it is provided that the feed area for the rollers in tooth gaps is located downstream in the pull-out direction of the storage compartment from the cooling space.
- the means are designed as an inclined plane, which the external toothing of the roller acted upon by an energy accumulator in the axial direction in the vicinity before its end section rolled off from the external toothing of the roller at the end of the closing movement of the storage compartment Engagement with the counter toothing urges, the roller is supported with a tread in the cold room.
- the inclined plane creates the prerequisites for being able to carry out the movement process of the externally toothed rollers around them out of engagement or with the counter toothing, in a particularly targeted manner, according to the available space.
- the roller substantially perpendicular to its axis in a fixed, equipped with a smooth tread and an externally toothed, slidably mounted in the axial direction of the roller section is divided, which with the counter-toothing in Intervention stands and which is supported on the stationary section by means of an energy store, the displaceably mounted section at least in the vicinity of its end section rolled off at the end of the closing movement of the storage compartment on the counter-toothing by the inclined plane against the action of the energy store out of engagement with the counter-toothing is.
- this provides a particularly simple and inexpensive support for the storage compartment in the closed state, in which the externally toothed section is out of engagement with the counter toothing.
