- the known from US 6,845,545 B2 cooling device further comprises means for generating a closing force, which are formed by a coil spring, which is stretched when opening the door and for a predetermined angular range exerts a closing force on the door or flap, so that in the said angular range an automatic and damped closing of the door takes place.
- the hinge has means for generating a closing force, wherein the means for generating a closing force having an eccentric and means which generate a force acting on the eccentric and dependent on the opening angle of the door or flap force. According to the invention it is thus provided that, depending on the opening angle, a closing force acting on the door or flap, which is caused by the fact that a force is exerted on an eccentric of the hinge.
- the eccentric is designed in such a way that, over an opening angle of 55 °, no forces inducing a closing movement act more on the door or flap.
- the door or flap remains in the position in which it was brought by the user. This prevents the door from automatically moving to the open end position after a certain opening angle or being automatically closed.
- damage to the device which may be caused by accidental opening of the door, can be prevented.
- the means which generate a force acting on the eccentric can be designed and arranged such that they exert a compressive force on the surface of the eccentric.
- the eccentric executed and arranged be that the pressure force in a first angular range on the eccentric generates no torque, so that the door or flap stops and generates a torque in a second angular range on the eccentric, which leads to closing the door or flap.
- the hinge may have a first hinge lever and a second hinge lever, one of which is pivotally connected to the door or flap and the other pivotally connected to the body of the device, wherein the eccentric and the means which generate a force acting on the eccentric, each on one of the hinge lever or both are pivotally mounted on one of the hinge lever.
- the hinge has a first hinge lever and a second hinge lever, one of which is pivotally connected to the door or flap and the other pivotally connected to the body of the device, and in that the hinge further comprises a pull lever which is pivotally mounted on the eccentric and on one of the hinge levers, wherein the axis, on which the pull lever is articulated to the eccentric, does not coincide with the axis of rotation of the eccentric.
- the torque acting on the eccentric is converted into a force that leads to the closing of the door or flap.
- the means which generate a force acting on the eccentric one or more compression springs and a roller or a sliding element which runs on the surface of the eccentric and acts on these.
- the means which exert a force acting on the eccentric force designed as leaf springs, torsion springs, coil springs or coil springs.
- the damper has a running in a cylinder piston and a piston connected to the piston rod, which is hinged to the hinge.
- the piston rod is directly connected to the hinge in connection.
- the piston rod is not directly in connection with the hinge, but that a damper lever is provided, which is pivotally connected to the piston rod and the hinge.
- the damper may be arranged such that it runs approximately parallel to the door formed by the door or flap or to the plane formed by the body front side regardless of the opening angle of the door or flap.
- one or more rollers are provided which are arranged on the damper lever and which are designed such that they absorb forces acting transversely to the piston rod of the damper at least when closing the door or flap. It is conceivable that the forces acting transversely to the piston rod are absorbed by the rolling friction when closing the door or flap, and when opening the door via one or more sliding elements which run in one or more grooves.
- one or more sliding elements are arranged on the damper lever directly or indirectly, which are guided in one or more grooves of a carrier. It is possible to provide an embodiment with one or more sliding elements and with one or more rollers. It is also conceivable to dispense with the roles and intercept transverse forces only when opening and closing exclusively on the sliding elements.
- the damper lever may be releasably connected to the piston rod such that it is coupled to the piston rod via a first opening angle of the door or flap and that it is decoupled from the piston rod via a second opening angle of the door or flap. In this way, a shortening of the required Dämpferweges can be achieved.
- the hinge has a slotted guide, in which the means which exert a force acting on the eccentric, are guided.
- the slotted guide By changing the slotted guide, the closing characteristic of the arrangement can be changed.
- the hinge may include a first lever and a second lever, one of which is pivotally connected to the door or flap and the other pivotally connected to the body of the device, wherein the slotted guide is arranged in one of the levers.
- the means which generate a force acting on the eccentric can be pivotally mounted about a pivot point, which is variable in position. In this way it is possible to change the door closing force or the closing behavior of the door. It is conceivable to form the articulation point by an eccentric pin.
- the damper has a running in a cylinder piston and a piston connected to the piston rod and the change in the damping behavior, the position of the piston is changed with respect to the damper cylinder.
- This relative movement can be achieved by changing the articulation / arrangement of the damper cylinder on a support or the like and / or by changing the articulation of the piston rod.

- a module which has a carrier, in or on which the damper and the hinge is arranged, wherein the module is used as a unit in the door or flap or in the body of the device.
- a modular design is particularly advantageous because the assembly cost is minimal and because a Mosanschlag LCD can be carried out with very little effort.
- such a modular design can also be dispensed with.
- disadvantages arise, for example, the door stop change, since then the individual components of the hinge or damper according to the invention must be installed directly into the door or in the body.
- the hinge and the damper and in particular the module according to claim 20 is arranged outside the cooled area of the device. Temperature fluctuations and the disadvantage of any condensation are effectively prevented in this way and the life of the hinge and damper is extended accordingly.
- hinge and the damper in an area of the door which lies outside the area surrounded by the door seal. This can be in the lower area or in the upper area of the door. The same applies to an arrangement of hinge and damper on the body.
- the damper and in particular the module can be arranged in the side facing the carcass of the door or in the door facing side of the body.
- the damper and in particular the module may be arranged substantially parallel to the plane formed by the door or substantially parallel to the plane formed by the front of the body.
- the module can be connected by a positive connection, in particular by a latching connection, and / or screw connection with the door or with the body of the device. It is conceivable, for example, that the module is fixed by positive locking the module in a particularly simple manner in the door or in the body of the device. If necessary, a fuse can be made by one or more screws.
- the invention further relates to a refrigerator and / or freezer with a door or flap for closing the device interior, with a hinge by means of which the door or flap is pivotable relative to the body of the device, wherein the hinge means for generating a closing direction in the Having door or flap acting closing force, as well as with a damper which applies at least over a part of the closing movement of the door or flap one of the closing movement of the door or flap opposing force, wherein the means for generating a closing force comprise a pull rope, on the one hand with the hinge and on the other hand with one or more springs in connection.

- FIG. 4 shows an exploded view of the hinge according to the invention with damper
- 5a to 5d show the hinge according to the invention with damper at different opening angles in an alternative embodiment
- FIG. 7 shows a detailed view of the hinge according to the invention
- FIG. 10 shows a perspective view of the damper received in the carrier with possibilities for changing the damping characteristic
- FIG. 11 further detailed views of the hinge according to the invention.
- Figure 1 shows a sectional view of the body 20 of a cooling device and the door 10 by means of which the device interior is closable.
- an oil / gas damper is characterized, which consists of a cylinder 202 in which a piston, not shown here runs. The piston is connected to a piston rod 204, the end of which can be seen in FIG.
- Figures 1a, 1b show the arrangement with the door closed, Figures 1c, 1d at an opening angle of 30 °, Figures 1e, 1f at an opening angle of 90 °, Figures 1g, 1h at an opening angle of 130 ° and the figures 1i, 1j at an opening angle of 165 °.
- the hinge connecting the body 20 to the door 10 consists of a first hinge lever 110 and a second hinge lever 120. Both hinge levers are pivotable about the pivot point 111 relative to each other.
- the first hinge lever 110 is articulated about the axis 21 on the body 20 of the device and the second hinge lever 120 is articulated about the axis 11 on the carrier 300, which is positively received and secured by screws in the door 10 of the device.
- the eccentric 100 On the hinge lever 120, the eccentric 100 is articulated about the axis 102.
- the eccentric 100 is connected via a pull lever 130 with the first hinge lever 110 in connection.
- the pull lever 130 is pivotally connected to the first hinge lever 110 and the eccentric in conjunction.
- the compression spring assembly Connected to the second hinge lever 120 is the compression spring assembly, which consists of a housing 141 (see FIG. 1b) in which two compression springs 140 are arranged.
- the carriage 142 In the housing 141, the carriage 142 is slidably received, in its end region directed towards the eccentric 100 at least one roller 150 is arranged, which runs on the eccentric surface of the eccentric 100.
- the compression springs exert a force on the carriage 142 which causes the roller 150 to be pressed onto the eccentric surface.
- the Druckfederanschung is thus not on the damper 200, but on the carrier 300th
- FIG. 1b shows an enlarged view of the hinge arrangement according to FIG. 1a.
- the components of the hinge, the damper 200 and the damper lever 155 are integrated with the door closed substantially in the door.
- the damper 200 is in this embodiment, regardless of the opening angle of the door 10 always in the plane of the door.
- Figure 1c, 1d shows the arrangement at a door opening angle of about 30 °. From this it is again clearly apparent that the pull lever 130 is articulated on the one hand to the eccentric 100 and on the other hand to the first hinge lever 110. Furthermore, it can be seen that the position of the roller 150 relative to the surface of the eccentric 100 changes with the opening of the door, as shown more clearly in the figures explained below.
- Figure 1d shows the arrangement according to Figure 1c in an enlarged view.
- FIGS. 1 g and 1 h show the door at an opening angle of approximately 130 °
- FIGS. 1 i and 1 j show the door at a door opening angle of approximately 165 °.
- the carrier 300 can be easily removed with the components arranged thereon and reused in another place, for example during a door stop change, without the necessity of disassembling and then reinstalling the components of the hinge or the damper individually.
- the carrier 300 or the module can be mounted, for example, at the bottom or at the top of the refrigerator or at a middle height arranged cross member.
- the carrier or the module is arranged such that there is no weakening of the insulation. This can be achieved, for example, by virtue of the fact that the damper 200 with this also the carrier 300 transversely, i. is inserted in the plane of the door 10 or in the plane formed by the carcass front in the transverse direction.
- the carrier 300 and the damper 200 are horizontally integrated in the door 10 or in the body 20 of the device.
- the damper can be arranged so that it is guided, so that shocks can be easily absorbed.
- the hinge is designed such that only loaded on train or pressure elements of the hinge exist, ie there are no torques in the articulated arms of the hinge.
- FIGS. 2a to 2e show perspective views of the arrangement according to the invention at opening angles of 0 °, 30 °, 90 °, 130 ° and 165 °. From this representation, it can be seen that the damper is arranged in a carrier 300, which is inserted as such in the door 10 or in the body 20 of the device.
- the sliding elements 170 are likewise arranged in the end region of the damper lever 155 and run in the groove 302 of the carrier 300 when closing and opening the door.
- FIGS. 3 a to 3 e show the arrangement according to the invention in a plan view at opening angles of 0 °, 30 °, 90 °, 130 ° and 165 ° and again illustrate the arrangement of the sliding element 170 in the groove 302 of the carrier 300.
- FIG. 4 shows the parts of the arrangement according to the invention in an exploded view.
- the carrier can be, for example, a plastic-encased metal part, which is locked in a corresponding recess of the door or the body and screwed if necessary.
- an exclusively positive fit is desirable, since in this way the carrier 300 is particularly easy to use and, if necessary, exchangeable or remountable.
- a carrier 300 By using a carrier 300, an optimum of rigidity and functions can be achieved. In particular, the occurring forces of the damper can be absorbed by the carrier 300. It can be beyond a Assembly-optimized design and a functional material selection for the sliding guide.
- Another advantage of the damper is that a rebound of the door when closing can be prevented with great speed.
- damper 200 is preferably locked in the carrier 300, without the further attachment means are required.
- FIGS. 5a to 5d show an arrangement in which the piston rod 204 is not in connection with the hinge via a damper lever but directly with the hinge.
- the structure of the hinge otherwise corresponds to that shown in Figures 1 to 4.
- FIGS. 5a to 5d show the arrangement also encompassed by the invention at an opening angle of 0 °, 90 °, 130 ° and 165 °.
- a carrier 300 is provided which is received in a recess of the door.
- the damper is pivotally mounted in the carrier 300.
- Figure 6 shows an arrangement in which the eccentric and the compression springs are replaced by a cable arrangement.
- the damper 200 pivots out of the door when the door is opened, but the door closing function is generated by a cable 400 which is connected to one of the hinge levers 110 at one end portion and the tension springs 410, 420 at the other end ,
- the cable 400 is connected to the hinge lever 110 approximately at the position in which in the embodiments according to Figures 1 to 4, the pull rod 130 is hinged to the hinge lever 110.
- FIG. 6a shows the arrangement with damper 200 and FIGS. 6b and 6c without damper.
- FIG. 7 shows the groove 302 of the carrier 300. It can be seen from this figure that the sliding elements 170 run in the groove 302. The support effect when closing is generated in the embodiment shown here via the roller 160. When opening, however, the upper groove side 303 forms the plant. Alternatively, it is conceivable to dispense with the roles and to take over the system not only when opening the door but also during the closing operation on the sliding elements 170 and via the groove 302.
- the reference numeral 304 indicates the engaging engagement of the groove 302 via pure sliding friction.
- Figure 8 shows an enlarged view of the eccentric 100 and the compression spring arrangement, by means of which on the rollers 150 on the surface of the eccentric 100, a compressive force is exerted.
- a compressive force is exerted.
- the spring force and thus the door closing force can be changed.
- Another way to influence the door closing force is that the articulation point of the housing 141 shown here, which receives the springs 140, done by means of an eccentric pin 190, with the result that so the spring force and the other also the spring line can be changed .
- the reference numeral 148 denotes the spring characteristic without adjustment and the reference numeral 149 the spring characteristic after the adjustment of the articulation point of the housing 141.
- a change in the door closing characteristic can also be effected by influencing the eccentric track, ie the surface of the eccentric 100, in cooperation with a likewise changed cam track, as can be seen from FIG.
- reference numeral 100 ' denotes the cam track and reference numeral 150 ' the cam track.
- FIG. 10 illustrates that a displacement of the cylinder 202 of the damper 200 relative to the piston rod 204 and thus also relative to the piston can bring about a significant change in the damping behavior.
- this relative movement can take place either via a stepless adjustment of the cylinder 202, i. the Dämpferanlenkung done, as indicated by the double arrow shown on the left, or a piston rod side Relativlagever capableung the Kolbenstangenanlenkung, as indicated by the double arrow shown on the right.
- FIG. 11 clarifies that the damper stroke limitation takes place via the abutment of the slider or sliders 170 on the groove end 302 ' .
- damper lever 155 which, as stated above, the roller 160 and the slider 170 connects to the hinge lever 120.
- These Damping characteristics based on the fact that the damper 200 never disengages over the entire door opening angle. This results in the advantage that unpleasant impact phenomena, which are neither desirable for the user nor for the material, are fundamentally avoided.
- the damper lever 155 it is also conceivable for the damper lever 155 to be coupled into and out of the slide carrier 170 in a defined door opening angle range. As a result, a shortening of the required Dämpferweges can be achieved. To avoid possible shocks, this decoupled state should be in an opening area, which takes place anyway only with little attenuation.
