EP3367026B1 - Refrigerated cabinet - Google Patents

Description

The present invention relates to refrigerated cabinets and individual features thereof, the features described below being part of the invention in any combination, provided that this does not result in technical contradictions.

It should also be noted that the individual aspects can also be implemented in product display furniture that does not allow the cooling of goods, such as. B. Food, serve. The individual features can therefore also be implemented in goods display furniture that is not used as refrigeration furniture.

In general, refrigerated cabinets are known in the prior art which have doors which can be pivoted about vertical pivot axes, the doors preferably being transparent and comprising one or more interconnected transparent glass panes.

Such doors have a lower and an upper pivot bearing or are in connection with one. While the lower door bearings are usually fixed in place (e.g. on a frame of the refrigerated cabinet to which other elements of the same are directly or indirectly fixed), the upper door bearings are mounted on or in a so-called furniture head or extend in each case in a rotary or swivel bearing, which is arranged on the furniture head.

Various door bearings are, for example, in the publications FR 1 061 618 A , U.S. 3,378,954 A , U.S. 3,005,227 A , EP 0 124 749 A2 , U.S. 5,138,743 A , DE 10 2015 012 304 A1 and WO 2008/050975 A1 disclosed. A hinge, particularly for automobile doors, is in the DE 100 26 667 A1 described. The furniture head is preferably supported downward only via a rear wall and / or the two outer side walls of the refrigerated cabinet, which are arranged to the left and right of several doors placed next to one another. According to the present invention, there are preferably no vertically extending supports or struts between the doors, since these would impair the view into the interior goods space.

Because of this mounting of the furniture head, it cannot be ruled out that it will sag downward in the course of time in the area between the side walls of the refrigerated cabinet. If the upper door bearings were to be fixed immovably in the axial direction of the pivot axis of the respective door, the above-mentioned deflection would cause the corresponding upper door bearings to tilt or block after a certain time.

According to a first aspect of the invention, it is therefore advantageous if the upper door bearings cause the respective doors to float. An advantageous embodiment of a corresponding upper door bearing is described below, wherein a corresponding door bearing can be used in several, preferably all, doors of the refrigerated cabinet.

It should also be pointed out that in addition to a door or a refrigerated cabinet with one or more corresponding upper door bearings, the upper door bearing as such is also the subject matter of the invention.

Finally, the door bearing according to the invention can be used not only in revolving or pivoting doors that can be rotated or pivoted about a vertical rotational or pivot axis between an open and a closed position. Rather, the door bearing can also be used as a bearing in sliding doors, preferably in refrigerated cabinets. The door according to the invention is also only a pivot door, for example. The door can also be designed as a sliding door.

The upper door hinge preferably comprises a door-side bearing section (which can be configured in one or more parts) for fixing the door hinge to the door. The door-side bearing section can, for example, have a connection section in the form of at least one bulge or indentation and / or a thread, via which it is or can be connected to a connection area of the door in a force-fitting and / or form-fitting manner and in particular non-rotatably with respect to the door.

The connection area of the door can be, for example, an insert fixed at least partially between two glass panes of the door, an attachment that at least partially encompasses one or more glass panes of the door, or a surface section of the door or one or more glass panes of the door. For example, the connecting section can be glued into a corresponding insert.

Furthermore, the upper door bearing comprises a furniture head-side bearing section (which can be configured in one or more parts) for direct or indirect fixation of the door bearing with respect to the furniture head. The furniture head-side bearing section can, for example, have a connecting section in the form of at least one bulge or indentation and / or a thread, via which it is connected to a connection area of the furniture head in a force-fitting and / or form-fitting manner.

For example, the bearing section on the furniture head side can be mounted in a ball or roller bearing, which in turn is fixed directly or indirectly to the furniture head. The bearing section on the furniture head side is preferably mounted so as to be rotatable but immovable in the vertical direction with respect to the furniture head. The bearing section on the furniture head side is preferably connected to a gearwheel or a pulley, in particular via a pivot bearing, the pulley in turn being connected to at least one (further) gearwheel or directly to a drive via at least one belt and / or the belt pulley or the gearwheel stands.

The bearing sections on the furniture head side of two adjacent doors are preferably in operative connection with a common drive.

According to the invention, the furniture head-side bearing section and the door-side bearing section are positively connected to one another and form the upper door bearing.

The bearing section on the furniture head side and the bearing section on the door side are preferably connected to one another in an exclusively form-fitting manner.

The bearing section on the furniture head side and the bearing section on the door side can preferably be separated from one another without tools and without releasing form-fitting connections if the upper door bearing or the door with a corresponding door bearing are not installed in a refrigerated cabinet.

The interlocking connection is designed such that the furniture head-side bearing section, when the door is built into a refrigerated cabinet, can be moved relative to the door-side bearing section, inter alia, in a direction that runs colinearly or parallel to the pivot axis of the door.

Furthermore, the connection between the two bearing sections should be designed in such a way that the furniture head-side bearing section can be tilted when installed. Tilting from an initial position, which both bearing sections have when the furniture head is not bent, is preferably possible horizontally in all directions.

Starting from an initial position in which the longitudinal axes of the two bearing sections are colinear with one another, the possible tilt angle is between 1 ° and 20 °, the tilt angle being based on the common longitudinal axis of the upper door bearing.

For this purpose, the door-side bearing section (or the furniture head-side bearing section) preferably has one or more depressions or recesses into which one or more bulges of the furniture head-side bearing section (or in the alternative case: the door-side bearing section) engage.

The door-side bearing section (alternatively the furniture head-side bearing section) preferably has an upwardly (or downwardly) open cavity into which an extension of the furniture head-side section (alternatively the door-side bearing section) engages. The dimensions of the cavity or the extension are dimensioned such that there is play between the cavity and the extension so that the extension can be moved in the cavity in the vertical direction or in the longitudinal direction of the upper door bearing (if the furniture head bends).

The dimensions should also be such that the extension (when the furniture head is bent as mentioned) can be tilted within the cavity.

Said cavity is preferably formed in that the bearing section having the cavity is designed as a sleeve which is open at least in the direction of the bearing section having the extension.

The extension preferably comprises a spherical end portion which is placed in the cavity.

Furthermore, the end portion preferably has at least one bulge protruding to the side, e.g. B. in the form of a bolt protruding laterally away from the end portion, which engages in a recess or a section of the wall delimiting the cavity.

Due to the interaction of the bulge and the recess at least partially surrounding it or the cutout at least partially surrounding the bulge, the two bearing sections are positively connected to one another in such a way that the bearing section on the furniture head side rotates about a vertical axis of rotation (which runs colinearly to the longitudinal axis of the upper door bearing ) causes the door-side bearing section to rotate about a vertical axis of rotation.

If the bearing section on the furniture head side is rotated around said axis of rotation with the aid of a drive, the bearing section on the door side also rotates and ultimately causes the door to open or close.

Another aspect relates to the drive of doors of a refrigerated cabinet, the door comprising an upper bearing section as described above or below. The refrigeration unit preferably has a plurality of correspondingly designed doors.

Furthermore, a refrigerated cabinet with several doors is described, each of which can be pivoted between an open position and a closed position with the aid of a drive and about a pivot axis, each door being in operative connection via a coupling with the drive assigned to it, the coupling from a transmission position in a release position can be transferred and vice versa, with a force generated by the drive being transferred to the door in the transfer position, and with the force transfer from the drive to the door being interrupted in the release position. Furthermore, it is provided that the coupling is designed to assume its release position when a force manually exerted on the door occurs A defined amount is reached, and the clutch can be transferred back into its transmission position after the force exerted manually on the door has ceased to exist.

The drive is preferably connected to one or more (preferably two) doors via a drive mechanism. The connection between the door and the drive preferably comprises at least two belt pulleys which are connected via a belt. While the first belt pulley can be connected directly or indirectly to an upper bearing section, the second belt pulley can be in operative connection with a gear wheel or a further belt pulley, which in turn are drivingly connected to the drive.

In particular, the upper door bearings of two adjacent doors should each be connected to a belt pulley in a rotationally fixed manner, each belt pulley being connected to a belt with a transmission connected to a drive, which in turn comprises at least two gear wheels. In each case one gear wheel is connected to a belt pulley, which in turn is connected via a belt to the belt pulley via a belt which is connected to an upper door bearing of a door.

The drive mechanism preferably comprises one coupling per door. The coupling normally has a force transmission position in which it passes on a force transmitted to it by the drive (preferably a torque) to at least one bearing section on the furniture head side.

The coupling is preferably arranged between a respective belt pulley and a gear wheel of the drive mechanism, wherein the belt pulley and the gear wheel can be mounted rotatably about a common axis of rotation.

If a defined force is exerted on the corresponding door, e.g. B. because the door is opened manually against the closing force of the drive or closed against the hold-open force of the drive, the clutch assumes a release position in which the transmission of the force from the drive to the corresponding door or in the opposite direction is interrupted. This prevents damage to the door or the drive. The door can be moved freely in relation to the drive.

The coupling can comprise two coupling elements which are pressed against one another with the aid of at least one loading element (e.g. a spring). Between the coupling elements there is preferably at least one power transmission element (e.g. a rough clutch disc) which ensures the desired power transmission when both coupling elements are pressed against each other and each assume their power transmission position.

The at least one force transmission element is preferably designed as a ball. One or both coupling elements (which are preferably designed as disks) preferably have one or more depressions in the area between the two coupling elements or their mutual contact surfaces. If the clutch is in its power transmission position, then the power transmission element or elements protrude at least partially into the recess (s) provided for it. If a first coupling element is now moved, a torque can be transmitted to the second coupling element through the form fit between the force transmission element and the recess.

If, on the other hand, a force acting against the drive is exerted on the door that is greater than a defined force, the force transmission element (s) leaves the recess (s), the coupling elements moving from one another in the direction of their common axis of rotation remove. The power transmission is interrupted.

In order to return the clutch to its starting position, the drive is then activated. The drive is operated as if it were to completely open the door (s) connected to it and close it completely before or afterwards. Here, the drive-side coupling element is also moved with respect to the stationary door-side coupling element until the force transmission elements again engage in the recesses in a form-fitting manner. The clutch is back in its power transmission position.

The drive mechanism preferably comprises at least one sensor element which detects the position of the door (s) connected to the drive. This can be a limit switch or a potentiometer, for example. The sensor element can preferably detect the exact angular position of the door. It is also conceivable that the sensor only detects the end positions (door open or closed) of the door. The sensor element can also be connected to a control of the drive and deactivate it or activate it in a specific drive direction when the door is in a specific position. For example, it would be conceivable that the door (s) are closed again after a certain time after they have been opened.

Furthermore, there should be a detector that detects the transition of the clutch from the power transmission position to the release position. For example, the detector could be designed as a proximity sensor which detects when one of the coupling elements moves in a predetermined direction during the transition from the force transmission position to the release position.

The coupling elements are preferably mounted about a common axis of rotation, at least one coupling element being moved away from the opposite coupling element in the direction of the axis of rotation against a load force when the release position is assumed. The detector preferably detects when one of the coupling elements is displaced in the axial direction of its axis of rotation (or both coupling elements are displaced in opposite directions).

Preferably, additionally or alternatively, the drive is assigned a sensor means which monitors the force transmitted by the drive to the door (s) assigned to the drive (in particular in the form of a torque). If this force exceeds a z. B. the amount stored in the control of the refrigerator or the drive, the drive is deactivated or stopped. This prevents the clutch from being disengaged if the door is moved against an obstacle when opening or closing, e.g. B. is not recognized by the sensor described below.

A corresponding sensor is therefore advantageous, which detects whether there is a person at a defined distance in front of the door monitored by the sensor. The drive can preferably not be activated if there is an obstacle (e.g. a shopping cart) in the path of movement of the door when the door is open, the obstacle being detected by the sensor. The drive can also preferably not be activated if there is an obstacle in the path of movement of the corresponding door when the door is closed, and this can also be detected by the sensor.

The doors could also have an actuating element which is connected to a control of the refrigerated cabinet, in particular the drive, and via which a customer can signal the refrigerated cabinet that he would like to open one or more doors.

An actuating element is preferably arranged on each door. Likewise, only one of several doors that are operatively connected to a common drive could have an actuating element.

In particular, the actuating element should be able to detect an approach or a touch of a human hand. For example, the actuating element could be designed as a capacitive sensor.

If the actuating element sends a signal to the controller when a hand is touched or approached, which is intended to activate the drive, this is preferably only activated when the named sensor detects that a person is in front of the refrigerated cabinet.

Features of refrigeration units 1 or their components are described below, with the individual features being able to be combined as desired, provided that this does not result in any obvious contradictions.

In addition, it should be pointed out that in figures which have elements or sections of the same type and thus represented in the same way, in some cases only one of the elements or sections is provided with a reference number in order to ensure a good overview. Finally, it should be made clear that not all sections / components in all figures are provided with a reference number if they have already been provided with a reference number in previous figures (compare e.g. Figures 3a, 3b , 4a, 4b ).

Figure 1 shows a front view of a refrigerated cabinet 1 with a frame 28 (ie a base element to which the other elements of the refrigerated cabinet 1 are attached directly or indirectly), several doors 2 pivotable about a vertical pivot axis 62, the doors 2 usually one or more Glass panes 17 which are spaced apart from one another and which allow a view into the interior of the refrigerated cabinet 1.

The storage of the doors 2 each comprises a lower door bearing, not shown, and an upper door bearing 4, so that each door 2 around its two bearings, for. B. with the help of a handle 3, are pivotable between an open and a closed position. Alternatively, it is of course also conceivable to move the doors 2 with the aid of a drive 20, as will be described in more detail below.

As Figure 1 further shows, the doors 2 are mounted on their upper door bearings 4 on or in the so-called furniture head 5. This is, for example, a horizontal cross strut that forms the upper area of the refrigerated cabinet 1 or is arranged behind a panel. Preferably, no vertical supports are arranged between the individual doors 2 in order not to impair the view into the interior of the refrigerated cabinet 1.

In particular, through so-called cold deformation of the said cross strut or the sections of the furniture head 5 to which the upper door bearings 4 are fixed, the furniture head 5 that fixes or guides the upper door bearings 4 deflects. A correspondingly deformed furniture head 5 is shown Figure 2 .

In order to ensure that the upper door bearings 4 do not tilt in the course of this deformation, upper door bearings 4 can now be used, as they are, for example, in FIG Figures 3a to 6 are shown.

In principle, the upper door bearings 4 in this case comprise a door-side bearing section 6, via which the upper door bearing 4 is connected to the door 2. This door-side bearing section 6 preferably has a connection 14 via which it can be connected in a form-fitting manner to a receptacle of the door 2. Alternatively, the connection 14 can also have a thread, an opening or a bulge or indentation. In any case, the connection 14 should be formed, the door-side bearing section 6 should be rigid, i. H. non-rotatable to connect with the door 2.

Furthermore, the upper door bearing 4 comprises a bearing section 7 on the furniture head side, via which the upper door bearing 4 is mounted in the furniture head 5 or a mounting of the furniture head 5 provided for this purpose. In order to fix the furniture head-side bearing section 7 with respect to the furniture head 5 or said mounting thereof, the furniture head-side bearing section 7 has a fixation 9 which, for. B. can be designed as a thread, opening, bulge or indentation or can comprise one of the sections mentioned.

The bearing section 7 on the furniture head side is preferably non-rotatably fixed by means of a fastening section 8 with a belt pulley 15 or a toothed wheel 21 connected, which in turn are stored in the area of the furniture head 5 (see Figure 6 ).

As Figure 3a also shows, the furniture head-side bearing section 7 has, in addition to the fastening section 8, a spherical head 11 with one or more coupling elements 42, which in the fully assembled state (see Figures 4a to 6 ) interact with one or more corresponding bulges 12 of a base body 13 of the door-side bearing section 6. The ball head 11 is connected to the fastening section 8 preferably via a connecting piece 10.

As a result, the door-side bearing section 6 is positively connected to the furniture head-side bearing section 7. Nevertheless, a relative movement between the door-side bearing section 6 and the furniture head-side bearing section 7 is possible in the vertical direction (cf. Figures 4a and 4b ).

Likewise, the furniture head-side bearing section 7 can be tilted or pivoted relative to the door-side bearing section 6, as is shown in the comparison of FIG Figures 5a and 5b indicates.

As a result, the upper door bearing 4 shown allows a tilt-free power transmission from a drive 20, which is preferably connected via belt 22 or directly to a pulley 15 or a gear 21, to the furniture head-side bearing section 7, which ultimately transfers the torque generated by the drive 20 to the The door-side bearing section 6 transfers and finally causes the door 2 to pivot.

In particular, this tilt-free power transmission remains even if the furniture head 5 bends and thus the spatial position of the mounting of the furniture head-side bearing section 7 or the aforementioned pulley 15 or the aforementioned gear 21 changes (with the lower door bearings and thus the doors 2 their keep spatial position).

Figure 6 now shows that the furniture head-side bearing section 7 is preferably connected non-rotatably to a belt pulley 15, which in turn is mounted in the area of the furniture head 5, this mounting not being explicitly shown.

The door-side bearing section 6, on the other hand, is fixed in a rotationally fixed manner on or in an insert 18 or an attachment of the door 2, which preferably extends at least partially between the glass panes 17 of the door 2. A sealing compound 19, which is preferably transparent, is also present in the edge region between the glass panes 17. A transparently cured adhesive can preferably be used.

If the belt pulley 15, as described below, is set in motion via a drive 20, the belt pulley 15 and finally also the door 2 rotates so that it can be pivoted between an open and a closed position.

One possible drive concept is shown Figure 7 representing a view from above. Two doors 2 are shown, each of which can be pivoted about a pivot axis 62. The doors 2 are shown in dashed lines because they are arranged below the indicated furniture head 5.

The pulleys 15 of the doors 2 are now connected to a gear 21 via a belt 22 each. The two gears 21 are finally connected to a drive 20 via further gears 21, the gear formed by the gears 21 being designed in such a way that the gear 21 driven by the drive 20 (top right) allows the doors 2 to pivot in opposite pivoting directions ( represented by the arrows), so that they are opened or closed at the same time when the drive 20 is activated.

It is advantageous if the drive 20 is either activated via a sensor 23, which in turn sends a signal to the drive 20 when a customer is in front of the refrigerated cabinet 1.

It is also advantageous if the activation of the drive 20 and thus the opening of the door 2 takes place with the aid of an actuating element. The sensor 23 can also be present in this case and ensure that the drive 20 can only be activated via the actuating element when a person is in the detection range of the sensor 23.

The closing of the doors 2 is also accomplished by the drive 20, in which case the drive 20 can be activated by a control after a certain time after the door 2 has been opened or after the sensor 23 detects that there is no longer any customer in front of the corresponding doors 2 is located.

The current position of the individual door 2 can also be recognized by a potentiometer 16, which is arranged, for example, in the area of the belt pulleys 15 mentioned (see FIG Figure 6 ). Likewise, the drive 20 could be stopped via the potentiometer 16 when the door 2 has reached its open or closed position.

Another beneficial feature is in the Figures 8a and 8b shown. As can be seen from these figures, the in Figure 7 The belt pulleys 15 shown are preferably connected via a coupling to the respectively assigned gear wheels 21, so that the power transmission between the belt pulley 15 and the gear wheel 21 and thus between the door 2 and the drive 20 can be interrupted.

In the example shown, the coupling comprises a drive-side coupling element 26 and a door-side coupling element 25 (both can be designed as disks), the two coupling elements 25, 26 being pressed against one another via a loading mechanism (e.g. a spring), not shown.

Furthermore, one or more force transmission elements 27 (preferably in the form of balls) are located between the two coupling elements 25, 26. The power transmission elements 27 protrude into recesses 74 of the coupling elements 25, 26 (see the section in Figure 9 ) and thus effect a form-fitting connection of the two coupling elements 25, 26 when the coupling elements 25, 26 are pressed against one another, when the force transmission elements 27 are located in the depressions 74 or protrude into them. If the drive-side coupling element 26, which is non-rotatably connected to the gear wheel 21, is set in rotation via the drive 20, the corresponding torque is transmitted to the door-side coupling element 25 and thus the belt pulley 15 and ultimately causes the door 2 to pivot.

If one of the doors 2 is now moved manually and against the drive or holding force of the drive 20 into a position deviating from the current position, the door-side coupling element 25 is rotated relative to the drive-side coupling element 26, the latter being held in its position by the drive 20 will.

Due to the relative movement between the drive-side coupling element 26 and the door-side coupling element 25, one of the coupling elements 25, 26 is deflected against the loading force of the above-mentioned loading mechanism, for example raised, as in FIG Figure 8b shown. As a result, the force transmission element (s) 27 are moved out of their depressions 74, so that the positive connection between the two coupling elements 25, 26 is interrupted. Moving the door 2 in this case does not damage the entire drive mechanism or the drive 20 as such.

A detector 24, e.g. B. a proximity sensor may be present. If this recognizes a movement of the coupling element 25 on the door side in the direction of its axis of rotation, the control system recognizes that the uncoupling process has been triggered.

As soon as the sensor 23 described above finally detects that there is no longer any person in front of the refrigerated cabinet 1, the drive 20 is set in motion. The drive 20 is operated in such a way that it assumes its two end positions one after the other, which it also assumes when it completely opens or closes the doors 2. As a result, the drive-side coupling element 26 sooner or later assumes a position in which it is in a position with respect to the door-side coupling element 25 in which the force transmission element or elements 27 interact again with the corresponding depressions 74. The coupling elements 25, 26 finally again have the in Figure 8a position shown and enable the desired power transmission between drive 20 and door (s) 2.

The present invention is not limited to the illustrated and described exemplary embodiments. Modifications within the scope of the claims are just as possible as any combination of the features described, even if they are shown and described in different parts of the description or the claims or in different exemplary embodiments, provided that there is no contradiction to the teaching of the independent claims.
