Definitions
- the present invention relates to a refrigeration device such as a freezer, a fridge-freezer or the like with a cold room in which at least one storage compartment is accessible through a pivotable flap.
- a tether made of plastic has been proposed in DE 198 177 65 A1, which is attached to the flap with a first holding element and to a wall of the cold space surrounding the flap with a second holding element, a relaxed one when the flap is closed , U-shaped configuration with a curved area surrounded by two straight legs and is stretched by opening the flap, the tether being completely straight when the flap reaches the horizontal stop position.
- tethers prove to be susceptible to wear; in particular, they tend to break in their curved area after prolonged use.
- the object of the present invention is to provide a refrigeration device in the cold room of which a storage compartment is accessible via a flap, the freedom of pivoting movement being limited by a tether, in which the lifespan of the tether is extended.
- the object is achieved in that the tether has a radius of curvature which is constant over its entire length between the two holding elements in a relaxed state.
- This radius of curvature can be finite; in this case, a bending load, which acts on the tether stretched when the flap is open, is distributed over its entire length instead of, as in the known construction, over only part of it.
- the radius of curvature of the tether is preferably infinite in the relaxed state, that is, the tether is straight in the relaxed state. Consequently, if the flap is open and the tether is loaded by the weight of the flap and possibly refrigerated goods placed on it temporarily, it is not also subjected to deformation at the same time, which further contributes to extending the service life.
- the tether To ensure that when the flap is closed, the tether is not pinched between the flap and the frame, it has proven to be expedient for the tether to be attached to the flap on the one hand so that it can be pivoted easily and on the other hand that it is not or difficult to pivot.
- the part of the tether attached to it protrudes obliquely towards the interior of the compartment at least on part of the closing path and urges the entire tether into the interior of the receiving compartment; at most towards the end of the closing movement, the tension of the tether should be large enough to cause its end attached to the flap to rotate.
- Fig. 1 schematically simplifies the upper section of a freezer, the two upper freezer compartments with one in a horizontal storage position pivotable and in this position flap held by flaps are closable, in a lateral section;
- Figure 2 is a partial section through the flap and the frame surrounding it at the level of line 11-11 of Fig. 1.
- FIG. 3 shows a view of a first embodiment of the tether according to the invention in a relaxed position
- FIG. 4 shows a section through the tether from FIG. 3, which is latched in a side wall of the flap, which is shown in detail;
- FIG. 5 is a view of a second embodiment of the tether
- FIG. 6 shows a section through the tether, which is latched in a side wall of the flap, according to a third embodiment
- Fig. 1 shows a simplified schematic representation of a household cabinet 10 designed as a standing appliance with a heat-insulating door 11 and a heat-insulating housing 12, which has an outer cladding 13, a heat insulation layer 14 produced by foaming and an inner cladding 15 produced by chipless shaping of a plastic board.
- This is provided on the door-side end sections of its two side walls 16 with deep-drawn, approximately vertically one above the other arranged blind hole-like receptacles 17 and is used to line a freezing space 18 accessible via the door 11.
- the freezing space 18 is arranged one above the other by an evaporator system 19 at uniform intervals , cooled essentially horizontally extending evaporator tiers 20. Due to the vertical distance between the evaporator shelves
- the freezer compartment is subdivided into refrigeration compartments 21 arranged one above the other, of which the lower ones have drawer-like compartments for storing frozen goods
- Receptacles 22 are equipped, while the two higher refrigeration compartments
- the door 21 on its front side facing the door 11 can be closed by a flap 30 which is explained in more detail below and can be pivoted about a horizontal axis.
- a flap 30 which is explained in more detail below and can be pivoted about a horizontal axis.
- the horizontal pivot axis is formed by two bearing bolts lying opposite one another in the same axis
- the holding bolt 24 comprises a locking section 29, which is provided for the purpose of holding an essentially shell-shaped flap 30 made of injection-molded plastic and used to close the overhead compartments 21.
- the flap 30 is formed on its side walls 31 with an open edge towards the freezer compartment 18, with a
- the flap 30 is pivotable about a horizontal axis of rotation, which by the
- the holding element 36 is connected in one piece to the tether 35, which is made, for example, of polyamide in a plastic injection molding process.
- a bearing eye 37 is formed, which is provided to on the holding part 25 of the retaining bolt
- Each flap 30 is provided on its two side walls 31 with a tether 35 each.
- the tether 35 In its relaxed configuration shown in Figure 3, the tether 35 is straight; this is also the configuration which, as shown in broken lines in FIG. 1, it adopts when the flap 30 is open.
- the tether 35 When the flap is closed, the tether 35, as shown in solid lines in FIG. 1, is uniformly curved over its entire length and extends in a circular arc into the interior of the storage compartment 21.
- the tether 35 can be pivoted about its two ends.
- the latching connection on the side wall 31 is designed such that the tether clamps more firmly at this end than on the holding bolt 24, the bearing section 27 of which engages around the bearing eye 37 with little play. In this way it is achieved that when the flap 30 closes, the orientation which projects obliquely from the flap 30 and which the tether 35 holds when the plate is open remains at least at the beginning, so that the tether is pushed back into the interior of the compartment 21 and not can be clamped between the side wall 31 of the flap 30 and the opposite side wall 16 of the inner lining 15.
- the straight tether of FIG. 3 can be mounted identically on both side walls 31 of the flap 30.
- the tether 35 is evenly curved in the relaxed state shown, but is just tensioned when the flap is open, as shown in FIG. 1.
- This tether 35 is thus subjected to bending stress both when the flap is closed and when it is open. Since the bending load is distributed over the entire length of the tether, it does not lead to any material fatigue worth mentioning.
- the tether is mounted so that the convex side of its curvature faces down when the flap 30 is partially open. In this way it is ensured that when the flap is closed, the tether 35 is secured in the FIG. 1 solid configuration passes over and does not deviate upwards from the stretched configuration.
- the tether of FIG. 5 has to be manufactured in a left or right version for the two side walls 31 of the flap 30. This eats avoid, however, if the one-piece molded on the tether retaining element 36 is replaced by a second bearing eye 38, which is the same dimension as the bearing eye 37 and, as shown in Fig. 6, a locking pin 39, which takes over the function of the retaining element 36 by the eyelet 38 and the through hole 34 of the flap 30 is inserted.
- FIG. 7 shows a section of a side wall 31 of the flap.
- the circular bore 34 is replaced here by two concentric elongated holes 40, through which a latching finger 41 of the holding element 36 extends. Since the locking fingers 41 are narrower than the elongated holes 40, the tether 35 has a limited freedom of pivoting movement on the side wall 31.
- an end position of the freedom of pivoting movement indicated in FIG. 7 by a dash-dotted outline of the tether 35, corresponds to the tether 35 tensioned when the flap is open, while the outline shown in dotted lines corresponds to an orientation of the tether when the flap is closed.
- the limited freedom of rotation ensures that, even in this closed position, the tether 35 protrudes obliquely into the interior of the refrigeration compartment 21 from the flap 30 and thus prevents the tether from getting caught between the flap 30 and the side walls 16.
