DETAILED DESCRIPTION

(19) FIG. 1 shows a perspective view of a door system 10 for a non-illustrated refrigeration device. In the embodiment shown, the door system 10 comprises four refrigeration device doors 12, wherein every refrigeration device door 12 comprises a corresponding bearing assembly 14. By means of the bearing assembly 14, the refrigeration device doors 12 may be pivotally mounted to a refrigeration device such that the refrigeration device doors 12 may be pivoted around a substantially vertically aligned pivot axis between a closed position, in which the refrigeration device is being closed by the refrigeration device door 12, and an open position, which allows access to the interior of the refrigeration device.

(20) In their main extension directions, the refrigeration device doors 12 extend substantially vertically; e.g., the refrigeration device doors 12 are employed with refrigerated shelves. The refrigeration device doors 12 each comprise a handle 58 and are, e.g., configured with double glazing between which an insulation gas is arranged in a free space. This can particularly be taken from FIG. 6. In this way, the refrigeration device doors 12 may efficiently thermally seal off respective corresponding refrigeration devices and at the same time additionally make it possible for the respective goods stored within the refrigeration devices to be discerned from outside when the doors are closed.

(21) In this context, the central refrigeration device doors 12 are mounted such that they pivot towards each other. The two outer refrigeration device doors 12, however, swing open outwardly. The bearing assembly 14 of the two central refrigeration device doors 12 shares a common bearing member, which saves space and weight. Here, the bearing assembly 14 comprises an upper bearing and a lower bearing for the refrigeration device doors 12. By means of the upper and lower bearings, a pivot axis of the respective refrigeration device door 12 is defined, which in this case substantially corresponds to an outer vertical edge of the refrigeration device door 12 and is stationary relative to the refrigeration device at the door system 10 mounted thereto.

(22) In the example shown in FIG. 1, the door system 10 further comprises a frame 16 which is formed by an upper ledge 18 and a lower ledge 20. By means of said frame 16, the door system 10 may be retrofitted at an already existing refrigeration device without difficulty. As an alternative, the frame 16 may already be a part of the refrigeration device, too, and, e.g., be fixed to the device's housing or firmly integrated within its housing. Both the frame 16 and parts of the bearing assembly 14 are, e.g., configured as metallic elements, particularly as food safe stainless steel elements. The handles 58 may, e.g., be configured as plastic elements in order to create a warm surface feel, and, e.g., be screwed together with respective glass panes of the refrigeration device door 12. The design of the frame 16, in particular the upper ledge 18, may very well be seen in the sectional lateral view according to FIG. 6.

(23) The design of the door system 10 may also very well be seen in the front view according to FIG. 2, the top view according to FIG. 3, and also in the lateral view according to FIG. 4. In these figures, it can also be seen that the door system 10 and, in particular, the refrigeration device doors 12 are substantially configured as flat, planar elements. However, it is also conceivable to design a corresponding door system 10 in which the refrigeration device doors 12 comprise, e.g., a certain curvature in the vertical direction and/or in the lateral extension. Also in this case, the door system 10 may be referred to as a substantially vertical door system.

(24) In FIG. 1, the vertical direction is marked with arrow 22, a horizontal direction is marked with arrow 24. These markings of the vertical direction and the horizontal direction are also maintained in the remaining figures, where applicable.

(25) As can particularly be seen in the detailed top view according to FIG. 5, which corresponds to the portion marked with Z in FIG. 3, the door system 10 further comprises one spring element 26 per refrigeration device door 12, said spring element being connected with the refrigeration device door 12 and suitable for engaging with the refrigeration device such that the respective refrigeration device door 12, at an opening angle smaller than a first critical angle, is being pushed into the closed position by the spring element 26, and, at an opening angle greater than a second critical angle, is being pushed into the open position by the spring element 26. For this purpose, with its first end 30 the spring element 26 is connected with the refrigeration device door 12 on the side of the door by means of an eccentric element 28. This may particularly well be taken from the top views of the door system 10 according to FIGS. 12 and 13 since respective parts which do not cover the eccentric element 28 are not illustrated therein.

(26) The eccentric element 28 is configured as an elongated, flat metal element which is fixed permanently with the refrigeration device door 12; in this case, e.g., by means of double screwing. Here, the first end 30 of the spring element 26 is pivotally mounted to the eccentric element 28. Due to the eccentric element 28, the spring element 26 is fixed spaced apart from the pivot axis of the refrigeration device door 12 in the horizontal direction. Here, in FIG. 5 the pivot axis of the refrigeration device door 12 approximately corresponds to, e.g., a screw connection 32 at which a retaining member 34 is connected with the frame 16. Furthermore, with its second end 36 on the side of the refrigeration device, the spring element 26 is attached at a fixed location to the frame 16 in a pivotable manner. By means of this fixation of the spring element 26, the spring element 26 exerts a closing or opening torque on the refrigeration device door 12 according to the opening angle of the refrigeration device door 12. In this way, the respective refrigeration device doors 12 may autonomously open, keep themselves open, and/or close.

(27) Preferably one of the bearing assemblies 14 according to FIG. 5 is provided per refrigeration device door 12. Here, the spring element 26 is configured as a gas pressure spring, which makes the spring element 26 particularly wear-resistant and protects it from contamination. Moreover, at the same time a damping member may be incorporated within the spring element 26 in a space-saving and cost-effective way.

(28) The respective segmental top views of the door system 10 according to FIGS. 8 to 11 again illustrate the operating principle of the spring element 26 during use of the refrigeration device door 12. As shown by arrow 38 in FIG. 8, pulling the handle 58 causes pivoting of the refrigeration device door 12 around its vertical pivot axis towards the outside in the horizontal direction. In this way, the interior of the refrigeration device can be accessed, e.g., in a supermarket in order for an end consumer to take out respective goods. During pivoting of the refrigeration device door 12, the spring element 26 is being compressed, which is demonstrated by arrow 40. A further compression of the spring element 26 when opening the refrigeration device door 12 farther is further shown in FIGS. 9 and 10. In case, e.g., in one of these positions of the refrigeration device door 12 the handle 58 is then being released, the spring element 26 will then exert a closing torque on the refrigeration device door 12 due to its being fixed spaced apart from the pivot axis of the refrigeration device door 12 by means of the eccentric element 28. By way of said torque, the refrigeration device door 12 is autonomously being turned back into the closed position in which the refrigeration device door 12 substantially abuts the frame 16 and/or a housing of the refrigeration device. As a consequence, the interior of the refrigeration device is being closed again and, e.g., cold air can no longer escape. In this way, a high cooling efficiency of the refrigeration device is being guaranteed. Additionally, users of the refrigeration device do not have to close the refrigeration device door 12 themselves, which renders the use for end consumers particularly convenient.

(29) However, the spring element 26 exerts said closing torque only up until an opening angle of the refrigeration device door 12 that is smaller than a first critical angle. In this context, the opening angle corresponds to an angle between a main extension plane of the access opening of the refrigeration device, i.e., a plane formed by the frame 16, and a main extension plane of the refrigeration device door 12. In the figures, for instance, the opening angle is marked with A. At an opening angle of approx. 90°, however, the effective direction of the spring tension of the spring element 26 corresponds to a straight line between the first end 30 and the second end 36 of the spring element 26 as well as the pivot axis of the refrigeration device door 12, whereby the compressive force of the spring element 26 no longer has a lever arm and, consequently, no longer exerts a torque on the refrigeration device door 12. At such an opening angle of the refrigeration device door 12, the door will not autonomously close again.

(30) At an opening angle A of more than 90°, however, the spring element 26 exerts a torque on the refrigeration device door 12, which causes the refrigeration device door 12 to open farther into the open position and/or also to be held in the open position. In this context, the open position corresponds to a maximum opening angle of the refrigeration device door 12, which in this case is, e.g., 120°. The autonomous opening of the refrigeration device door 12 is illustrated, e.g., in further top views in FIGS. 10 and 11. Accordingly, arrow 42 shows how in the open position of the refrigeration device door 12 the spring element 26 continues to exert a force that keeps open the refrigeration device door 12. The fact that the refrigeration device door 12 opens and also keeps itself open autonomously causes the refrigeration device door 12 to autonomously resort to and remain in its maximum open position. In this way, larger amounts of goods may then easily and rapidly be taken out of or deposited in the interior by means of the refrigeration device's access opening that is particularly broadly unblocked. For instance, supermarket staff can thus particularly easily stow larger amounts of goods on the respective refrigerated shelves. Then, for example, the access opening is released far enough for larger packages, such as pallets and cardboard boxes of goods, to be easily deposited. At the same time, no snap-shutting refrigeration device door 12 will threaten to impede this work, as is the case with, e.g., an inclined bearing for an autonomous closing of the door. If the wide access to the interior of the refrigeration device is no longer required, the refrigeration device door 12 may be closed by hand far enough for its opening angle to be smaller than the first critical angle. As of this point, the refrigeration device door 12 will again close autonomously.

(31) The opening angle as of which the refrigeration device door 12 is autonomously being brought into the open position by the spring element 26 is also referred to as the second critical angle. Said second critical angle may, e.g., be 90°. In this case, the first critical angle and the second critical angle are thus identical so that there is only one angular point at which the refrigeration device door 12 is not autonomously being pushed into either the open position or the closed position by the spring element 26. Respective deviations from this angular point at which no autonomous opening or closing of the door occurs may in this context particularly be of technical nature, e.g., frictional.

(32) Furthermore, the door system 10 comprises a restriction member 44. In the present case, the restriction member 44 is configured as a coupling rod and restricts the maximum opening angle of the refrigeration device door 12, thus making it possible, inter alia, to prevent the spring element 26 from overstretching. For this purpose, the coupling rod, i.e., the restriction member 44, is pivotally mounted to the refrigeration device door 12 with its first end 46 on the side of the door. At its second end 48, the restriction member 44 is slidably received in a guiding rail 50 in a pivotable and displaceable manner. In this context, the guiding rail 50 can particularly well be seen in FIG. 6. At its end 48, the coupling rod is mounted in a groove of the guiding rail 50 with a sliding head 52. Upon a pivoting movement for opening the refrigeration device door 12, the second end 48 of the restriction member 44 moves in the direction of the pivot axis, i.e., in the direction of an end on the side of the pivot axis of the guiding rail 50, as is illustrated by arrow 54 in FIG. 8. In the guiding rail 50, a stopper (not illustrated) is provided, and/or the groove of the guiding rail 50 may also end at a certain point so that the second end 48 of the restriction member 44 may not move further in the direction marked by arrow 54. Such a position can, e.g., be taken from FIG. 11. In this way, a further pivoting movement of the refrigeration device door 12 is prevented by the restriction member 44. Accordingly, the maximum opening angle has been reached. By an alteration of the length of the restriction member 44, an alteration of the position of the stopper and/or an alteration of the length and/or the position of the guiding rail 50 on the refrigeration device, a different maximum opening angle may thus be set in order to, e.g., prevent the refrigeration device door 12 in its maximum open position from clashing with opposite refrigeration device doors 12 pivoting in the opposite direction and/or with other obstacles such as, e.g., walls, columns, or shelves.

(33) As may be taken from the sectional front view according to FIG. 7, with its first end 46 the restriction member 44 is only plugged on a pin member 56 of the refrigeration device door 12. In this way, the restriction member 44 may quickly and easily be released by lifting from the pin member 56. Thus, the refrigeration device door 12 may then be opened manually beyond the maximum opening angle for maintenance and assembly purposes.

(34) The bearing assembly 14 of the respective refrigeration device doors 12 is reinforced by means of the restriction member 44. Being mounted in a manner spaced-apart from the pivot axis, the restriction member 44 may particularly well withstand respective loads of misuse. For instance, the restriction member 44 may also take up respective bearing loads when shorter people prop themselves on the handle 58 in order to reach goods stored on higher shelves.

(35) Due to the design with the eccentric element 28, the spring element 26 exerts a particularly high torque on the refrigeration device door 12 when it is opened particularly far or closed particularly far. In order to prevent an excessively hard stopping of the refrigeration device door 12 in its open position and its closed position, the door system 10 may comprise at least one damping member per refrigeration device door 12. For instance, the spring element 26 that is configured as a gas pressure spring may comprise an integrated damping by means of which an inadvertently strong acceleration of the refrigeration device door 12 during its autonomously closing and opening may be prevented. In this way, the longevity of the door system 10 is increased and the user gets a higher-quality impression. As an alternative or in addition, e.g., a damping member may also be provided in the guiding rail 50 and/or at the sliding head 52 or other positions of the restriction member 44.

(36) The first critical angle, below which the refrigeration device door 12 closes autonomously, and the second critical angle, above which the refrigeration device door 12 opens autonomously, may be affected by the form of the eccentric element 28 and its relative alignment towards the refrigeration device door 12. As an alternative or in addition, the two critical angles may also be determined by the form of the spring element 26 and/or the position of the mounting of the second end 36 of the spring element 26 to the frame 16.

(37) The present example shows that the door system 10 allows for a space-saving, autonomous closing of the refrigeration device door 12. The space of the upper guiding unit including the upper ledge 18 is, e.g., only 28-34 mm without the refrigeration device door 12. In this context, the depth corresponds to an extension into the sheet plane according to FIG. 2. A space height of this unit is, e.g., only 67-73 mm, wherein the height corresponds to an extension in the vertical direction. A length of the restriction member 44 is, e.g., only 220-240 mm between its two pivotal points. At a total weight of the refrigeration device door 12 of approx. 12-40 kg and a spacing of the first end 30 of the spring element 26 of at least 35 mm from the pivot axis of the refrigeration device door 12, a spring element 26 being able to generate a maximum compressive force of 50 N is sufficient.

(38) Conclusively, FIG. 12 and FIG. 13 are to illustrate again the interaction between the eccentric element 28 and the spring element 26, and how said interaction has an impact on the respective critical angles. FIG. 12 shows a lever arm H1 which has the compressive force generated by the spring element 26 with respect to the pivot axis of the refrigeration device door 12. This results in a closing torque, which is illustrated by the arrow 60 in FIG. 12. In this context, the lever arm is dependent on the opening angle A of the refrigeration device door since it results from a distance perpendicular to the effective direction of the force generated by the spring element 26 to the pivot axis of the refrigeration device door 12. Accordingly, at an opening angle A according to FIG. 13, the lever arm H2 has a different length and faces away from instead of towards the frame 16. Accordingly, the position of the door according to FIG. 13 results in a torque with a different amount and a different direction of rotation than the position of the door according to FIG. 12. Here, it is an opening torque, which is illustrated by arrow 62.

(39) FIG. 13 demonstrates another position of the spring element 26 by a dashed line 64. In this position, the main extension direction of the spring element 26 exactly points to the pivot axis of the refrigeration device door 12, i.e., its first end 30 and its second end 36 form a straight line which lies on the pivot axis. Thus, the compressive force generated by the spring element 26 has a lever arm of zero with respect to the pivot axis of the refrigeration device door 12. Accordingly, there is no opening or closing torque. In this context, this position corresponds to the critical angle beyond which the refrigeration device door 12 closes autonomously and above which it opens autonomously. Deviations and thus two critical angles may particularly form by means of friction and a lever arm at which there is no sufficiently high torque in order to overcome respective frictional forces. In this context, a second dashed line 66 illustrates in FIG. 13 the position of the door at said critical angle, said dashed line 66 being perpendicular to the dashed line 64 and corresponding to an opening angle that is marked with B in FIG. 13. In this way, it is clearly evident how the critical angle may be altered by means of the position of the eccentric element 28 and the spring element 26 relative to the pivot axis and by means of its respective form.

(40) Due to the lever arm's dependency on the critical angle of the refrigeration device door 12, by means of only one spring element 26 the interaction of the eccentric element 28 and the spring element 26 allows for generating torques which close or open the refrigeration device door 12 depending on the opening angle. This involves a mechanically simple and robust design which does particularly not require any additional movable and/or active, e.g., electrically controlled, elements.

(41) Thus, the door system 10 provides for a refrigeration device which, during normal use by an end customer, definitely guarantees a high energy efficiency by a reliable closing of the interior of the refrigeration device, while at the same time a particularly convenient and quick loading and unloading of higher amounts of goods is enabled by means of the integrated function of keeping open the refrigeration device door 12.

(42) FIGS. 14 to 20 illustrate a door system according to a further preferred embodiment of the present invention. All the features described above with respect to other embodiments may also be combined with the present embodiment according to the invention. In particular, the features described below with respect to the offset of the pivot axis are also preferred embodiments for the other embodiments.

(43) FIG. 14 shows a perspective view of a door system for a refrigeration device according said further preferred embodiment of the present invention. FIG. 14 illustrates only two refrigeration device doors 12. However, it is clear to the person skilled in the art that further refrigeration device doors 12 may follow. Both at their upper sides (indicated by the circle marked with R) and their lower sides (indicated by the circle marked with S), the refrigeration device doors 12 are mounted to a refrigeration device by means of a bearing assembly 14, with only a part of the frame 16 of the refrigeration device being illustrated. FIG. 17 shows a lateral perspective view of a door 12 of the door system according to FIG. 14 with the corresponding bearing assemblies 14.

(44) FIG. 15 shows a perspective view of the portion of the door system according to FIG. 14 marked with R. FIG. 16 shows a perspective view of the portion of the door system according to FIG. 14 marked with S. FIG. 18 shows a lateral perspective view of the portion of the door according to FIG. 17 marked with T. FIG. 19 shows a lateral perspective view of the portion of the door according to FIG. 17 marked with U.

(45) As can be taken from FIGS. 15 and 18, the upper bearing assemblies 14 are connected with the frame 16 of the refrigeration device by means of a screw connection 32 and a retaining member 34. At the lower end of the refrigeration device door 12, the door is pivotally mounted in a corresponding recess within the frame 16 by means of a joint pin 68.

(46) FIG. 20 shows a top view of the door according to FIG. 17. The refrigeration device door 12 preferably comprises a center plane defined by the two outer surfaces 70 and 72. The center plane is the plane (or curved surface) whose distance to the two outer surfaces 70, 72 is the same at any point (measured perpendicular to the tangent at the plane or the curved surface at the respective point). Furthermore, the bearing assembly 14 defines a pivot axis S that is preferably offset with respect to the center plane, i.e., the center surface. Preferably, the distance d1 between the pivot axis and the center plane, i.e., the center surface, is at least 3 mm, more preferably at least 5 mm, even more preferably at least 6 mm, even more preferably at least 7 mm, and particularly preferably at least 8 mm. In the illustrated embodiment, the distance d1 is 8 mm.

(47) With this offset, the refrigeration device door according to the invention—when in the mounted state, i.e., when being pivotally mounted to a refrigeration device—allows for an outwardly displaced pivot and/or rotary axis. As already explained above, this, in turn, preferably allows for mounting the refrigeration device door as close to the front side of the refrigeration device as possible without restricting its movability. In other words, according to the invention, the gap existing between the refrigeration device door on the one hand and the front side of the refrigeration device on the other hand may be configured to be very narrow, which, inter alia, makes it possible to do without additional sealing measures. This is particularly advantageous when the refrigeration device door is substantially configured to be completely transparent, i.e., when there are transparent spacers between, e.g., the two transparent panes of the refrigeration device door, so that also the lateral edge sections of the refrigeration device door are transparent.

(48) It is further preferred that the refrigeration device door 12 comprises a lateral plane 74 defined by the lateral front wall, and that the distance d2 between the pivot axis S and the lateral plane is at least 3 mm, more preferably at least 5 mm, even more preferably at least 6 mm, even more preferably at least 7 mm, and particularly preferably at least 8 mm. In the illustrated embodiment, the distance d2 is 9.5 mm. Also this offset to the inside may contribute to keeping the gap between the refrigeration device and the refrigeration device door as narrow as possible and, at the same time, doing without additional measures such as, e.g., rounding off the lateral front wall.
