Definitions
- the present invention relates to a refrigerator with a cold room, in which a receiving compartment is divided and accessible via a hinged flap.
- a receiving compartment is divided and accessible via a hinged flap.
- Such a device may, for example, be a refrigerator with compartmentalized frost compartment, or a freezer whose refrigeration compartment is subdivided into a plurality of compartments.
- z. B. from DE 198 17 765 A1 discloses to provide a tether of which engages one end of the flap and the other on a wall of the inner container.
- the tether is made of a stretch-resistant but elastically flexible plastic material. In its relaxed position, the tether is U-shaped curved, so that it fits into a gap between the wall of the inner container and a side wall of the flap opposite this wall, without overhanging the outline of this flank.
- a survival of the tether is undesirable, on the one hand because a visible projection of the tether forward is aesthetically unsatisfactory, on the other hand because the above tether could hinder the closing of the door of the refrigerator.
- a supernatant of the tether into the interior of the receiving compartment could cause the tether when closing the flap of chilled goods in the receiving compartment and makes it difficult to close the door.
- the U-shape of the tether has the disadvantage that the tether is bending-stressed when the door is opened. If the length of the tether is dimensioned to be extended when the flap is opened to a horizontal position, then the tautness of the tether may easily cause the flap to stop before reaching the horizontal and thus gain access to the tether Storage compartment impeded.
- the object of the invention is to provide a refrigerator with an opening-limited flap, wherein the flap assumes a well-defined stop position in the open state in which it is resilient without giving way.
- the object is achieved by a refrigerator with a cold room and at least one accessible in the cold room via a hinged flap receiving compartment, wherein the flap in an open position by a on the flap and on a wall of the
- Tether of the open position of the tether drives the flap rather in this open position, as it prevents them from reaching them.
- the tether is preferably rotatably supported on the wall and on the flap to minimize its bending stress when opening and closing the flap.
- the tether preferably comprises two end pieces and a middle piece, the center piece is more flexible than the two end pieces, so that when the flap is closed, the tether U -like shape, which finds place between a side edge of the flap and the wall of the cold room, without substantially over the edges of the side edge.
- the increased flexibility of the center piece can be achieved in a simple manner by forming the center piece with a smaller cross-sectional area than the end pieces.
- a height difference between the types of attack of the tether on the flap in its closed position and on the wall should correspond to a difference in length of the two end sections, so that the end sections can take a space-saving, substantially vertical orientation with the flap closed.
- FIG. 1 schematically simplifies the upper portion of a freezer, the two upper freezers are closed with a pivotable in a horizontal storage position and held in this position by tethers flap, in a lateral section;
- FIG. 2 shows a partial section through the flap and the surrounding frame in height of the line II of Fig. 1.
- Fig. 3 is a partial perspective view of a tether and serving for its attachment to the inner wall of the freezer bolt;
- FIG. 4 is a perspective view of the inner wall of the freezer body facing side of the bolt.
- Fig. 1 shows a simplified schematic representation of a trained as a household appliance freezer 10 with a heat-insulating door 11 and a heat-insulating housing 12, which has an outer lining 13, a heat-insulating layer 14 produced by foaming and an inner lining 15 produced by deep-drawing a plastic plate.
- This is provided at the door-side end portions of its two side walls 16 with integrally formed by deep drawing, approximately vertically stacked blind hole-like receptacles 17 and serves for lining a accessible via the door 11 freezer compartment 18th
- the freezer compartment 18 is cooled by an evaporator system 19 with uniformly spaced superimposed, substantially horizontally extending evaporator storage 20 cooled. Due to the vertical distance of the evaporator bearings
- the freezer compartment is divided into superimposed cold compartments 21, of which the lower lying for storage of frozen food with drawer-like
- Receiving containers 22 are equipped, while the two higher-lying cold storage
- each side wall 16 On each side wall 16 are each two of the receptacles 17 at the level of each of the upper compartments 21.
- the horizontal pivot axis is formed in the present embodiment by two axially equal to each other opposite bearing pin 23, which with a shaft, not shown in the lower lying of the two blind holes 17 on the two side walls 16 are fixed.
- the retaining pin 24 for limiting the insertion depth of the shaft 25 in the receptacles 17 has a flange 26 which contacts the side wall 16 around the receptacle 17.
- a bearing portion 27 connects, which is closed at its end opposite the flange 26 by a retaining bead 28.
- the retaining pin 24 comprises a locking portion 29, which serve for holding an already mentioned above, for closing the overhead cold compartments 21, is provided substantially cup-shaped flap 30 made of plastic injection molding.
- the flap 30 is provided on its side walls 31 with edge open to the freezer compartment 18 out, provided with an undercut receptacles 32, in which the locking portion 29 is able to submerge.
- the above-mentioned bearing pins 23 define the pivot axis of the flap 30 by engaging with their not shown by the side walls 16 projecting pins each in a formed on the side walls 31 of the flap 30 recess 33.
- the recess 33 is a slot which extends in the closed position of the flap 30 in the vertical direction and thereby allows for releasing the flap 30 from the locking portion 29, an upward movement of the flap 30.
- a tether 35 shown in Fig. 4 holding member 36 which with the through holes 34 in the form of a releasable Locking connection is assembled.
- the holding element 36 is integrally connected to the tether 35 produced, for example, from polyamide in the plastic injection molding process.
- a bearing lug 37 which is provided to be rotatably supported on a bearing portion of the retaining bolt 24 between the flange 26 and the retaining bead 28.
- Each flap 30 is provided at its two side walls 31 each with a tether 35.
- the tethers 35 are elastically U-shaped curved; if, as indicated in Fig. 1 by a dashed outline, one of the flaps 30 is open and oriented horizontally, their tethers 35 are elongated and relaxed and keep the flap 30 in the horizontal position.
- Fig. 3 shows an enlarged perspective view of the bearing lug 37 of a tether 35 and a retaining bolt 24 which is provided to support the bearing lug 37.
- the above-mentioned locking portion 29 is shown in Fig. 3 only schematically transparent, with dashed outlines, shown on the one hand to the outer periphery of the Garwulstes
- Arretianssabites 29 is not a necessary feature of the support pin 24, but that for locking the flap 30 in the closed position, other means than those in
- Fig. 1 may be provided shown.
- the outer periphery of the retaining bead 28 is substantially circular, except for four radially inwardly directed notches 38, which are each distributed at an angular distance of 90 ° to each other on the circumference of the bead 28.
- the lowest points of the notches 38 lie on a circle whose diameter is just as large or at most slightly larger than the diameter of the circular bearing section 27.
- the bearing lug 37 comprises two sections 39, 40, which follow one another in the direction of the longitudinal axis of the retaining bolt 24.
- the retaining bolt facing portion 39 has a free inner cross section which is complementary to the cross section of the retaining bead 28 is formed substantially circular with four radially inwardly directed projections 41.
- the dimensions of the bead 28 and section 39 are adapted to each other so that the portion 39 can be pushed over the retaining bead 28 under pressure, when the projections 41 engage in the notches 38. Since four projections 41 and notches 38 are present, there are four rotational positions in which the bearing lug 37 can be pushed over the retaining bead 28.
- the bearing lug 37 is not rotatable; only when the projections 41 have passed the notches 38 and have reached the bearing portion 27, the bearing lug 37 is rotatable about the retaining pin 24. Since unlike the eyelets conventional tethers the bearing lug 37 can pass the retaining bead 28 only in a certain rotational position, it is excluded that the bearing lug 37 gradually led up in the course of a rotational movement on the retaining bead 28 and gets stuck.
- the second portion 40 of the bearing lug 37 has a circular free cross-section whose diameter is slightly larger than that of the retaining bead 28. This portion 40 surrounds the outer periphery of the retaining bead 28 when the bearing lug 37 is mounted on the retaining bolt 24 and thus protects the outer periphery of Garwulstes 28 from injury that could deform this and could lead to the bearing lug 37 only with simultaneous damage to the Garwustes 28 and can be removed.
- FIG. 4 is a perspective view of the retaining bolt 24, seen from its side wall 31 facing side.
- Formed on the peripheral surface of the hollow cylindrical shaft 25 are four ribs 42 which extend in the longitudinal direction of the shaft 25 and only two of which are visible in the figure.
- the height of the ribs 42 is selected in dependence on the accuracy with which the formation of the receptacle 17 in the inner lining 15 is controlled so that when inserting the retaining pin 24 in the receptacle 17, only the ribs 42, but not the supporting cylindrical Body of the shaft 25 come into contact with the walls of the receptacle 17 and thereby slightly deform the receptacle 17 or deformed by it.
- Fig. 5 shows a perspective view of the tether 35 together with the molded at its ends holding elements 36, 37.
- the holding member 36 for anchoring to the through hole 34 of the flap 30 comprises a hollow cylindrical shaft 44 whose outer diameter minus a game corresponds to the diameter of the through hole 34 and a hollow frusto-conical portion 45 extending the shank 44, of which two faces the larger faces the shank 44 and has a slightly larger diameter than the through-hole 34.
- a slot 46 is formed in shaft 44 and truncated cone 45 so that they can be compressed to press the truncated cone 45 through the through hole 34 and thus anchor the tether 35 to the flap 30.
- the tuck strap 35 injection-molded from elastic plastic material is elongated in the relaxed state, so that the relaxed state corresponds to the open position of the flap 30.
- the tension of the tether 35 thus supports the opening of the flap 30, unlike a conventional, in a curved configuration in the closed position of the flap 30 relaxed tether. While in a relaxed curved tether the flap 30 may need to have a considerable weight to reach their open stop position in which the tether is elongated against the spring force of the tether 30 at all, with the inventive tether this position regardless of the weight Flap 30 or the rigidity of the tether 35 reached.
- the tether 35 can therefore be made strong enough to carry a parked on the open flap 30 load.
- the tether 35 is divided between the support members 36, 37 in two strong end pieces 48, 49 and a weaker center piece 50. Concentrated on the center piece 50 in the closed position of the flap 30, the deflection of the tether 35, ie the tether takes an approximately U shaped configuration, wherein the end pieces 48, 49 not or only slightly curved outer legs of the U form. A difference in the lengths of the end pieces 48, 49 corresponds to a height difference of the holding elements 36, 37 with the flap closed, so that in this position the tether 35, as shown in Fig. 1, vertically downwards and not or at most insignificant on the side wall 31st the flap 30 protrudes.
