Definitions

  • the present invention relates to a pane system for a refrigerated appliance for closing and opening a goods compartment of the refrigerated appliance, the pane system comprising a plurality of movable panes and the panes being movable between an open position and a closed position. Furthermore, the invention relates to a refrigerated cabinet.
  • Refrigerated cabinets with generic pane systems are known in the prior art and are used, for example, in supermarkets to present the foodstuffs for sale to the customer.
  • Common pane systems here have horizontally displaceable sliding doors or revolving glass doors.
  • a well-known version of a refrigerated cabinet with horizontally sliding sliding doors is, for example, in DE 20 2011 052 121 U1 described.
  • refrigerated cabinets with sliding doors have the disadvantage that the sliding doors, which can be displaced in parallel in the horizontal direction, block the adjacent area or the adjacent sliding door in the displaced position. This means that only a part of the refrigerated cabinet can be opened at the same time.
  • a well-known version of a refrigerated cabinet with revolving glass doors is, for example, in DE 10 2008 010 586 A1 described.
  • refrigerated cabinets with rotating glass doors have the disadvantage of being an obstacle in front of the refrigerated cabinet in their open position.
  • the object of the present invention is to eliminate the disadvantages known from the prior art.
  • the task is in particular to provide a pane system for a refrigerated cabinet and a refrigerated cabinet equipped therewith create, which simplifies the accessibility to the goods space and / or reduces the space required in front of the refrigerated cabinet.
  • a pane system for a refrigerated appliance for closing and opening a goods compartment of the refrigerated appliance, the pane system comprising a plurality of movable panes and the panes being movable between an open position and a closed position.
  • a refrigerated cabinet is a piece of furniture that cools the goods in its goods compartment.
  • the refrigerated cabinet can be designed as a simple refrigerated shelf with a large number of product compartments.
  • the refrigerated cabinet can have an additional refrigerated space, which is used to temporarily store the goods, with the goods being able to be moved from the refrigerated space to the goods space that is accessible from the front, if required.
  • there is at least one door or roller arrangement between the goods space and the refrigerated space which can be opened if necessary to allow goods to be refilled from the refrigerated space into the goods space, in particular from the rear of the goods compartments.
  • a first goods shelf can be arranged in the refrigerated space and a second goods shelf spaced from it can be arranged in the goods space. These two product shelves can be separated from each other by the door or roller arrangement.
  • a passageway and/or storage area can be arranged between the product shelves.
  • Such an arrangement of the refrigerated cabinet with a refrigerated space and a goods space has the advantage that a common cooling unit for cooling the refrigerated cabinet can be designed in a simpler and more cost-effective manner.
  • the pane system is designed as a separate unit that is not directly connected to either the cooling unit or the cooling room.
  • the refrigerated cabinet can preferably be operated at a temperature between 9°C and 0°C prevailing in the goods compartment.
  • the refrigerated cabinet can also be operated as a deep-freeze cabinet with a temperature of -18°C or colder.
  • the closed position is to be understood as meaning the position of the panes in which the panes close off the goods compartment of the refrigerated appliance from the outside.
  • panes when the panes are all in their closed position, when the pane system is used as intended (i.e. when the pane system is connected to a refrigerated appliance), they are essentially arranged next to one another in such a way that they form a continuous pane surface that extends the goods space to the outside locked. In their closed position, the panes are preferably arranged vertically one above the other and lined up next to one another.
  • panes are in their open position, access to the goods compartment is free, so that goods can be removed from or placed in the refrigerated cabinet.
  • two or more panes are arranged at least partially one behind the other, preferably viewed perpendicularly to their direction of movement, so that the pane surface formed by the panes is smaller in the open position than in the closed position.
  • a pane is to be understood here as a transparent element which, in its closed position, at least thermally closes the goods compartment of the refrigerated appliance from the outside. Due to the transparent design, the goods room and the goods stored in it can be viewed from the outside.
  • the pane can comprise a single pane element, ie a single pane of glass or plastic (so-called “single glass”) or also a plurality of pane elements (a plurality of glass or plastic panes).
  • the at least one pane element can be made of glass or plastic be, with a plurality of disk elements, these can differ from each other.
  • at least one interior space can be formed between the plurality of disk elements, which is filled with a gas or gas mixture, for example an inert gas or air.
  • the panes are preferably insulating glass panes, in which at least two pane elements are connected and kept at a distance by means of spacers, so that a cavity is formed between the panes, which is closed to the outside by the spacers and the pane elements.
  • the spacers can be formed at least partially and/or in sections by a transparently cured adhesive.
  • the discs are preferably designed as flat discs in the form of plates. Alternatively, the panes can also be curved, at least in sections.
  • two pulleys are connected with the aid of at least one traction device and form a pair of pulleys, the traction device being guided via a deflection, which is preferably arranged above the pulleys when the pulley system is used as intended, and the pulleys connected to the traction device being on different sides the deflection are located, so that a movement of a first disk in a first direction of movement causes a movement of the second disk in a second direction of movement.
  • the deflection can be formed from one or more elements (preferably deflection rollers), with at least one of the elements of the deflection being arranged above the discs and deflecting the traction means when the disc system is used as intended. Individual elements of the deflection, in particular also individual deflection rollers, if the deflection comprises several such deflection rollers, can also be arranged behind or in front of the discs when the disc system is used as intended.
  • a traction means is to be understood here as a means which remains essentially dimensionally stable, in particular when subjected to a tensile load. Since the at least one traction mechanism is deflected above the discs during the intended use of the pane system, the at least one traction mechanism is designed to be flexible, at least in sections, in the area of the deflection.
  • the respective traction means is formed by a rope, a chain or particularly preferably by a belt.
  • the traction means is therefore an elongate, preferably flexible, element which is connected to two disks and is guided over the deflection.
  • a pair of disks is to be understood as meaning two disks which are connected to one another with the aid of the at least one traction mechanism.
  • Each pair of disks has a first disk and a second disk, with the movement of the respective first disk in the first direction of movement leading to a movement of the respective second disk in the second direction of movement.
  • Both the first direction of movement and the second direction of movement can change independently of one another and/or together in the course of their movement. This is particularly the case when the discs are at least partially curved and move on a curved trajectory.
  • the two discs of the pair of discs are each arranged on different sides of the deflection on the traction mechanism. As a result, a weight force of the respective disk acts on each side of the deflection.
  • This weight force thus loads the traction mechanism under tension, specifically on different sides of the deflection. If one of the disks is moved with the introduction of an external motive force, the other disk also moves due to the deflection, preferably in the opposite direction. The two discs are therefore hanging at different ends of the traction mechanism, with the traction mechanism being deflected by the upper deflection.
  • pane system has only one pair of panes and thus a first pane and a second pane, these are in their closed position minimally or not at all spaced apart. Each of the panes covers half of the access to the goods area. In the open position, the first pane and the second pane of the pair of panes are at a maximum distance from one another.
  • the first disks of each pair of disks move in the first direction of movement.
  • the second discs of each pair of discs move in the second direction of movement.
  • the panes of the several pairs of panes are in their closed position, preferably arranged in a row in the vertical direction (whereby they can slightly overlap or abut one another), whereby the access to the goods compartment is closed. Each of the panes only covers a fraction of the access to the goods area. If the pane system has two pairs of panes, the first pair of panes is arranged in its closed position in the middle for access to the goods compartment.
  • the first disk of the second pair of disks is arranged adjacent to the first disk of the first pair of disks and the second disk of the second pair of disks is arranged adjacent to the second disk of the first pair of disks.
  • the respective first panes and the respective second panes of the pane pairs can largely or completely overlap in their open position. This results in a different movement distance of the respective disks of different pairs of disks.
  • the disks of the respective disk pairs move at different movement speeds.
  • the movement speeds of the two due to the connection using the at least one traction means, the amount of disks in a pair of disks is the same and differs only in its direction of movement.
  • the first and second discs of the first pair of discs are minimally or not at all spaced apart. In this way, the cooling effect in the goods space can be guaranteed. Access to the goods, in particular the groceries, is blocked by the panes in the closed position. In the open position, the first pane and the second pane of each pair of panes are at a maximum distance from one another.
  • the at least one traction means is guided around the deflection in such a way that the discs arranged on the different sides of the deflection are suspended.
  • the first disk of a disk pair is fastened to a first end of the traction means and the second disk of the same disk pair is fastened to a second end of the traction means.
  • the weight of the two disks of a pair of disks is similar, preferably identical, so that the weight forces on the different sides of the deflection are essentially neutralized or canceled out. If the first pane is shifted in the first direction of movement, the second pane is also shifted in the second direction of movement without any additional exertion of force.
  • the second disk of a disk pair is lowered from the closed position to the open position by the weight acting on it when the first disk of the disk pair is moved upwards from its closed position to its open position by an external force.
  • the panes can be moved very easily between the closed position and the open position.
  • the panes can be stopped in different intermediate positions when moving between the open position and the closed position (or in the opposite direction), as a result of which the pane system can remain open or closed in sections.
  • the disk system includes a guide arrangement, with the aid of which the disks are guided during their movement. If the first disc of the pair of discs is moved in the first direction of movement, a force acts on the second disc of the pair of discs due to the deflection, as a result of which it is moved in the second direction of movement.
  • the guide arrangement guides the panes in their movement. If the disks are preferably in the form of flat disks, the guide arrangement guides the disks in constant directions of movement. If the panes are designed as curved panes, the guide arrangement can guide the panes along a path of movement following the bending of the panes. On the path of movement of the curved panes, the respective directions of movement of the panes change and are therefore not constant along the movement.
  • first direction of movement is essentially opposite to the second direction of movement.
  • the directions of movement are preferably kept constant by the guide arrangement.
  • the kinetic force acting on one of the discs of the pair of discs is transmitted via the traction mechanism to the other disc of the pair of discs and acts in the opposite direction here due to the deflection of the kinetic force introduced.
  • first direction of movement and/or the second direction of movement forms an angle with a vertical direction which is less than 90°, preferably less than 30°, particularly preferably equal to 0°.
  • the pane system can therefore not only be used in refrigerated shelves, but also in chest freezers whose goods compartment is accessible from above.
  • the vertical direction is the direction in which the weight of the panes acts. If one of the directions of movement forms an angle equal to 0° with the vertical direction, then these directions of movement and the vertical direction are parallel to one another. If the first direction of movement points in the positive vertical direction, then the second direction of movement points essentially in the opposite direction in the negative vertical direction.
  • a frictional force can act which counteracts the movement.
  • the frictional force can act between the moving disks and the guide arrangement. If the angle spanned between the vertical direction and the first and/or second direction of movement is small, the frictional force between the moving discs and the guide arrangement is also small. In addition, a small angle has the advantage that the space required for the refrigeration appliance can be minimized with such a pane system, while at the same time there is a large goods space.
  • each disk is preferably connected to one end of a traction means via its two upper, lateral corners.
  • the panes are of rectangular design.
  • the panes preferably have a pane width of 500 mm to 2000 mm.
  • the panes preferably have a pane height of 250 mm to 1000 mm.
  • the disk system has an even number of disks, with two disks connected with the aid of the at least one traction means, preferably with the aid of two traction means each, forming a disk pair.
  • the first disc of the pair of discs moves in the first direction of movement and the second disc moves in the second direction of movement, due to the connection via the traction device or devices, when the first disc is moved manually or with the help of the drive described below. So only one disc of a pair of discs has to be moved at a time in order to cause the second disc to move at the same time).
  • one of the first disks is connected to one of the second disks via the at least one traction mechanism. If the disk system has an even number of disks, no additional counterweight is required for a single disk. If a disk system has four disks, for example, these are designed as two pairs of disks, with the disks of a respective pair of disks being connected to at least one, preferably two, traction means.
  • a disk system has six disks, for example, these are divided into three pairs of disks, each with at least one traction mechanism.

  • the deflection 7 is arranged in a deflection box 13 .
  • the deflection box 13 can identify a receiving area for the first panes 3a, 3c.
  • the two second panes 3b, 3d are arranged in a drawer box 14 at the lower end of the pane system 2a, 2b.
  • the slide-in box 14 also has a movably mounted cover element 15 for covering. In the open position, this cover element 15 can serve as a step in order to ensure better access to the goods compartment 4 .
  • a damping element 16 are each arranged, which the movement of the discs 3a - 3d can dampen.
  • two damping elements 16 can be arranged in the area of the slide-in box 14 and in the area of the deflection box 13 in order to dampen each pane 3a-3d individually. If the panes 3a - 3d are moved from their closed position, as shown in Figure 3a, to their open position, as shown in Figure 3b shown, moved, the respective movement can be damped by means of the damping elements 16 in such a way that the discs 3a - 3d come to a standstill.
  • an advertising element visible from the front can be arranged in the area of the deflection box 13 and/or in the area of the slide-in box 14 .
  • the advertising element can be an electronic display and/or a showcase for displaying advertising. Additional price labeling arrangements can also be arranged in the area of access to the goods compartment 4, in particular on the drawer 14, on the cover element 15, on the panes 3a - 3d or on the deflection box 13, by means of which the prices of the goods in the goods compartment 4 can be marked.
  • the pane system 2 can have an impact protection element on the front side and thus on the side of the goods space 4 facing away from the goods space 4 in the area of the deflection box 13 .
  • This impact protection can extend along the refrigeration appliance 1 in a bead-like manner and serve to protect the pane system 2 and in particular the panes 3a-3d from shopping trolleys or the like.
  • FIG 4 shows a front view of a pane system 2 according to the invention in an open position according to an alternative embodiment.
  • the pane system 2 is shown here.
  • the pane system 2 can therefore also be retrofitted to existing refrigeration units 1 .
  • the pane system 2 has a lighting device 17 in each case.
  • the lighting device 17 can be, for example, an LED strip arranged on the back of the respective guide rail 5 .
  • the drive 18 is operatively connected (e.g. via a gear) to the connecting shaft 10a, which connects the deflection rollers 9a, 9b to one another, so that operation of the drive 18 causes a rotary movement of the connecting shaft 10a in one or the other direction of rotation and thus a movement of the traction means 6a, 6b and the disks 3a-3d connected thereto (depending on whether the disks 3a-3d are to be moved from their open position to their closed position or from their closed position to their open position).
  • a sensor device 19 detects the movement in front of the disk system 2.
  • the drive 18 can be controlled by means of the control unit 20 in such a way that the disks 3a-3d open when the sensor device 19 detects movement or close when the movement is not detected.
  • the control unit 20 can control the drive 18 in such a way that it drives the rotatable unit or the deflection and thereby the panes 3a - 3d move between the open position shown here and the closed position in their respective direction of movement BR1, BR2.
  • FIG 5 shows a section in the area of a deflection 7 of a disk system 2a, 2b according to the invention according to a further exemplary embodiment.
  • Discs 3a - 3d are unlike the previous ones embodiments of figures 1 - 4 not shown in the present embodiment for reasons of clarity.
  • the discs 3a - 3d, not shown, are similar to the previous embodiments of the Figures 1 - 4 , out by means of the guide sections 8a, 8b of the guide rails 5 and moved by means of the traction means 6a, 6b.
  • the deflection rollers 9a, 9b and the guide rollers 11a, 11b are aligned normal to the horizontal direction HR or are plugged onto one of the connecting shafts 10a, 10b in the horizontal direction HR.
  • the deflection rollers 9a, 9b and the guide rollers 11a - 11d aligned normal to a transverse direction QR.
  • This arrangement of the deflection rollers 9a, 9b and the guide rollers 11a-11d leads to less space being required in the transverse direction QR.
  • the additionally required space requirement in the horizontal direction HR is given or is available due to the pane width or due to the spacing of the guide rails 5 .
  • the deflection rollers 9a, 9b have different diameters.
  • the second deflection roller 9b has a smaller diameter and is therefore invisibly hidden behind the larger first deflection roller 9a in the exemplary embodiment shown. However, this can be seen from the course of the second traction means 6b, which narrows in the background of the first deflection roller 9a.
  • the different diameters of the two deflection rollers 9a, 9b result in different movement speeds of the traction means 6a, 6b, which are connected to discs 3a - 3d (see Fig Figures 1-4 ) are connectable.
  • the two traction means 6a, 6b on one side of the pane are preferably one to three traction means widths apart in the transverse direction QR.
  • the traction means 6a, 6b run essentially directly next to one another or are only separated from at least part of at least one of the guide sections 8a, 8b.
  • the width is the width of the traction mechanism to understand one of the traction means 6a, 6b in the transverse direction QR.
  • the two deflection rollers 9a, 9b and two of the guide rollers 11a, 11b and 11c, 11d are also arranged directly next to one another.
  • the deflection 7 of the embodiment of figure 5 in contrast to the previous exemplary embodiments, four guide rollers 11a - 11d on each side of the disc. Since the deflection rollers 9a, 9b are offset inwards in the horizontal direction HR, both traction means 6a, 6b on both sides of the deflection roller 9a, 9b can be guided outwards by means of the four guide rollers 11a-11d.
  • the guide rollers 11a and 11c guide the first traction means 6a on different sides of the deflection roller 9a.
  • the guide rollers 11b and 11d guide the second traction means 6b on different sides of the deflection roller 9b.
  • the guide rollers 11a, 11b are offset by at least one traction means thickness relative to the guide rollers 11c, 11d.
  • the thickness of the traction means extends in the horizontal direction HR.
  • the diameter of the guide rollers 11a, 11b can differ from the diameter of the guide rollers 11c, 11d. This can additionally or alternatively ensure that the different sides of the traction means 6a, 6b are guided past one another in the horizontal direction HR.
  • the first connecting shaft 10a couples the two deflection rollers 9a, 9b of the different sides of the disk to one another. Since the deflection rollers 9a, 9b run normal to the transverse direction QR and the connecting shaft 10a runs normal to the horizontal direction HR, the deflection 7 has at least one gear 21. In the exemplary embodiment shown, two gears 21 are shown which, as bevel gears, bring the respective deflection rollers 9a, 9b of one side of the disk into an operative connection with the first connecting shaft 10a.
  • a drive pinion 22 which is arranged on the connecting shaft 10a in a rotationally and/or non-displaceably fixed manner, the deflection rollers 9a, 9b are driven.
  • a drive 18 according to the previous embodiment of the figure 4 find use.
