Description

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. However, such 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. However, such 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.

The object is achieved by a pane system for a refrigerated cabinet and a refrigerated cabinet with the features of the independent patent claims.

A pane system for a refrigerated appliance is proposed 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.

Likewise, 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. In particular, 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. In addition, 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.

In particular, 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.

If, on the other hand, the 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.

In the open position, 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. In addition, 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.

According to the invention, 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. In particular, 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.

If the 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.

If the disk system has several pairs of disks, 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.

In order to open the access to the goods space completely and preferably in a space-saving manner in the open position, 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.

In order to ensure these different movement distances of the respective first disks of different disk pairs and the respective second disks of different disk pairs at the same time, the disks of the respective disk pairs move at different movement speeds. The movement speeds of the two On the other hand, 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.

In the closed position, 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. In particular, 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. In particular, 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. In this way, the panes can be moved very easily between the closed position and the open position. In addition, 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.

It is advantageous if 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.

There are advantages if the 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.

It is also advantageous if the 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.

In general, it should be pointed out at this point that spatial information (e.g. above or below, vertically or horizontally) always applies refer to the intended use of the pane system, i.e. if the pane system is part of a refrigeration appliance and is arranged in the area of a front side facing the customer and closes a goods compartment that is accessible from the front (closed position of the panes) or makes it accessible from the outside (open position of the panes).

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.

The smaller the angle spanned, the smaller the deviation between the first and/or second direction of movement from the direction of the weight force.

When the disks are moved in or through the guide arrangement, 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.

There are advantages when two panes are connected with the aid of at least two traction means, the two traction means being spaced apart from one another in a horizontal direction, in particular essentially over a pane width seen in the horizontal direction. Thereby the discs can be suspended at their two lateral ends in the horizontal direction. Tilting of the pane can thus be prevented and the lowest possible frictional force in relation to the guide arrangement can thereby be ensured. Each disk is preferably connected to one end of a traction means via its two upper, lateral corners. In this case in particular, the panes are of rectangular design. The panes preferably have a pane width of 500 mm to 2000 mm. In addition, the panes preferably have a pane height of 250 mm to 1000 mm.

It is also advantageous if 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).

In order to ensure that the weight of the disks is balanced, 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.

If a disk system has six disks, for example, these are divided into three pairs of disks, each with at least one traction mechanism. This even number of panes are arranged in their closed position in such a way that together they close the access to the goods compartment of the refrigerated appliance and form a common pane surface. For this purpose, the panes can overlap one another in the closed position or rest against one another at their horizontally extending end faces.

In general, the panes should have a rectangular shape with two opposite and vertically running faces and two opposite horizontally running faces, the four faces defining the rectangular shape of the pane.

In their open position, on the other hand, the panes are arranged in such a way that they completely open up access to the goods compartment.

There are also advantages if, with at least four pulleys, two of the traction devices of different pairs of pulleys are spaced apart from one another at most three traction device widths in the horizontal direction of the pulleys (i.e. in their width direction when looking at the pulleys from the front) and/or in a transverse direction. The width of one of the traction means is to be understood as the width of the traction means. A traction mechanism width is many times smaller than the pulley width. If the two traction devices are less than one traction device width apart, then they are essentially arranged directly next to one another. As a result, an independent movement of the two pairs of disks and their connecting traction means can be ensured without the traction means rubbing against one another.

It is also advantageous if the guide arrangement has at least one guide rail with at least one guide section for guiding at least one of the panes. The at least one pane moves within the guide section between its open position and its closed position. The at least one guide section of the at least one guide rail can additionally together with the at least a pane to close the goods compartment in such a way that, in the closed position, there is no exchange of cool air in the goods compartment with the warm air outside. The panes are preferably each guided in their own guide section in the region of their vertically running end faces.

Two guide rails are preferably assigned to one of the panes and are spaced apart from one another by at least one pane width. The pane width and the distance between the guide rails are therefore dependent on each other. As already described above, the disc width is preferably 500 mm to 2000 mm. However, pane widths of less than 500mm and more than 2000mm are also conceivable. The greater the pane width, the greater the access to the goods area.

It is also advantageous if the guide rail has at least two guide sections arranged one behind the other for guiding at least two panes of different pairs of panes arranged one behind the other. The first disks of different pairs of disks preferably move at different speeds of movement in the same direction of movement. This also applies to the second pane of the pair of panes. The two guide sections arranged one behind the other can ensure a compact design of the pane system while at the same time providing full access to the goods compartment. The first pane and the second pane of a pair of panes can be guided in the same guide section since they preferably do not overlap.

It is also conceivable that the first pane and the second pane of a pair of panes are guided in different guide sections. This can ensure, among other things, that in the closed position of the pane system none of the pane pairs abut one another or each pane at least partially overlaps another pane. If the pane system has two pairs of panes, the two panes of the first pair of panes in such an arrangement preferably overlap in the middle for access to the goods compartment.

Similarly, the guide rail can have three guide sections arranged one behind the other for guiding three pairs of panes or correspondingly several guide sections arranged one behind the other for guiding several pairs of panes.

There are also advantages if each pane is guided on both sides in the horizontal direction of the pane by a guide rail or a guide section. This ensures that the panes are guided evenly. In addition, the goods space can be closed on both sides in the closed position, in particular without a gap, by the guide rails arranged on both sides.

It is also conceivable that the panes are not guided by a guide rail but by some other means in their movement. For example, it would be conceivable for horizontally adjacent panes of two pane systems to cause the panes to guide one another. For example, the disks could have lateral guide elements that engage in one another, so that a disk is guided during its movement by the guide element of an adjacent disk or is held on a desired path of movement.

It is also advantageous if the deflection has at least one deflection roller for deflecting and/or at least one guide roller for guiding the at least one traction means. A deflection roller is to be understood as meaning a roller which deflects the at least one traction means and guides it and absorbs at least part, preferably all, of the weight of the associated pair of disks. As a leadership role here is a To understand role that leads the traction means in particular after the deflection through the deflection roller, wherein the guide roller is preferably in contact with the side facing away from the deflection roller with the traction means. The traction means therefore preferably runs between the deflection roller and the guide roller.

There are also advantages if at least two of the deflection rollers and/or at least two of the guide rollers are coupled to one another in such a way that they form a rotatable unit, in particular via at least one connecting shaft. The deflection rollers and/or the guide rollers can be coupled to one another directly and/or indirectly via at least one connecting shaft. The deflection rollers, the guide rollers and/or the connecting shafts are coupled in their rotational movement. The at least two deflection rollers and/or the at least two guide rollers of the rotatable unit therefore rotate at the same speed. For example, two traction means of a pair of disks can be coupled to one another in such a way that they move at the same speed.

There are also advantages if the at least two deflection rollers and/or the at least two guide rollers of the rotatable unit have different diameters for deflecting and/or guiding at least two associated traction means moving at different movement speeds. The rotational speed of the rotatable unit can lead to different peripheral speeds due to the different diameters of the at least two deflection rollers and/or the at least two guide rollers. The at least two deflection rollers and/or the at least two guide rollers with their different diameters provide a translation of the movement speeds of the at least two traction means. As a result, the pairs of disks arranged thereon can also be moved at different movement speeds.

As already described, access to the goods compartment can be closed off with several pairs of panes. The panes are lined up in a vertical direction or arranged in an overlapping manner. In their closed position, the panes are preferably arranged one below the other in the vertical direction. If the pane system has two pairs of panes with a total of four panes, the first two panes lined up next to each other cover the upper half and the two second panes cover the lower half of the access to the goods compartment. In order to open the access to the goods space completely and preferably in a space-saving manner in the open position, the respective first panes in the upper area and the respective second panes in the lower area of the pane system can be arranged partially one behind the other. In order for the discs of the respective pairs of discs to move from different vertical positions in their closed position to the same vertical position in their open position, they must move at different movement speeds. This can be ensured using the traction means moving at different movement speeds.

Furthermore, it is advantageous if the at least one deflection roller and/or the at least one guide roller has teeth. In this way, a non-positive connection can be increased by means of friction between the at least one deflection roller and/or the at least one guide roller to the traction mechanism. Additionally or alternatively, a form-fitting connection between the at least one deflection roller and/or the at least one guide roller and the traction means can be ensured if this is designed as a toothed belt. If at least two deflection rollers and/or at least two guide rollers of the rotatable unit each have a toothing, the synchronization between them can be improved due to the form fit.

There are advantages if the pane system has at least one slide-in box, in particular at the lower end of the at least one guide rail when used as intended, for pushing in and receiving at least one of the movable panes, preferably half of the panes, in its open position, with the slide-in box is preferably covered with the aid of a movably mounted cover element when the panes moving downward during the transition from the closed position to the open position are in their open position. The slide-in box can serve as a protection system for the panes in their open position. The cover element, which covers the panes in the vertical direction in their open position, can move with the panes due to their movement. Thus, the cover member is hinged up by the panes as they move vertically upwards through contact with the panes. If the panes move vertically downwards from the closed position to the open position, the cover element can be folded down, for example due to gravity and/or with the aid of a spring, when the panes have assumed a position below the cover element. When the panes are in the open position, the cover element can also serve as a step for better access to the goods compartment.

It is also advantageous if the pane system, in particular in the area of the at least one drawer unit and/or in the area of the deflection or above the panes, has at least one damping element (e.g. in the form of a plastic buffer or a gas spring) for damping the at least one movable pane when Having reached its open position and / or its closed position. With the aid of the damping element, the speed of movement of the at least one movable pane can be gently reduced to a standstill when it reaches its open position and/or its closed position. In this way, damage to the panes can be avoided.

It is also advantageous if the pane system has at least one lighting device, particularly in the area of the guide arrangement. The goods compartment can be illuminated by means of the lighting device. If the lighting device is preferably located in the area of the guide arrangement, indirect lighting of the goods compartment is ensured.

It is advantageous if the disc system, in particular in the area of the rotatable unit, has a drive for driving at least one of the discs, in particular by means of the rotatable unit. The drive can drive the disks directly or indirectly, preferably by means of the rotatable unit, in such a way that they are moved between the open position and the closed position. The drive can, for example, drive the connecting shaft of the rotatable unit and thus the deflection rollers coupled thereto. The rotational movement of the deflection rollers is translated via the traction means into the first direction of movement at the first end of the traction means and into the second direction of movement at the second end of the traction means. In order to transfer the rotational movement of the deflection roller to the movement of the traction mechanism without slippage, both can be toothed. The guide rollers are preferably not operatively connected to the drive, but rotate through contact with the traction means when they are moved by rotating deflection rollers. Additionally or alternatively, the drive can drive at least one of the traction means directly or indirectly, in particular via a drive pinion. For this purpose, for example, the toothed drive pinion can be operatively connected to the toothed traction mechanism. The drive can be designed as an electric motor, for example.

Furthermore, it is advantageous if the pane system has a control unit, a safety device, a sensor device and/or a switching device. At least one sensor is to be understood as a sensor device, which detects movements in the vicinity of the refrigeration appliance, in particular in front of the pane system. For example, the movement of people in front of the pane system can be detected. The sensor can be designed, for example, as a light barrier or ultrasonic sensor or as some other movement or proximity sensor.

A switching device is to be understood as a device which has at least one switch which is arranged and can be actuated in the vicinity of the refrigerated appliance, in particular in front of the pane system and/or on the guide arrangement or the guide rails. For example, people who are in front of the pane system can signal their desire to open the panes. The switch can be designed, for example, as a light barrier, keypad, foot switch or other mechanical or electrical switch.

A control unit is a unit that influences the behavior of technical components of the target system. For example, the control unit can control the drive of the pane system in such a way that the panes open when movement is detected by the sensor device and/or when or after the switching device is actuated. If, within a predefined time, in particular within less than 30 seconds, no more movements or people are detected in front of the goods compartment and/or the switching device is no longer or not actuated again, the panes of the pane system are closed again by the drive. For this purpose, the control unit can control the drive in such a way that it drives the rotatable unit and the panes are thereby moved between the closed position and the open position.

A safety device is to be understood as a device that can record or detect possible interfering contours or people in the functional area of the pane system, ie in the area of movement of the panes. In this way, an intervention by persons during the movement of the panes can be detected via the safety device and the movement of the panes can be stopped. A safety device is to be understood in particular as a device that requires an increased amount of force on a drive side of the recognizes the drive and can thus detect a collision with a person or an interfering contour. A safety device is also to be understood as a device that can limit the force or torque of the drive. The closing force of the disc system can be defined via the torque of the drive. The safety device can be part of the sensor device, the drive and/or the control unit.

Additionally or alternatively, the controller can control the drive in such a way that when closing the drive and thus the movement of the panes are throttled before the closed position is reached. Due to the slower movement, people have the opportunity to clear the access to the goods area in good time before the window system reaches its closed position. The safety device is thus integrated in the drive or in the control.

Likewise, the safety device and/or another safety device can be arranged on the guide arrangement and/or the panes. This safety device is preferably designed as a clamping element, so that if the drive and/or the control and/or at least one of the traction means fails or is defective, at least one of the discs is clamped and/or tilted towards the guide arrangement by means of the clamping element. In this way, an uncontrolled closing of the pane system after such a defect can be avoided.

A person and/or interfering contour detected by the sensor device and/or switching device and/or safety device can be forwarded to the control unit in such a way that the movement of the panes is stopped. For example, accidents caused by pinching can be avoided. The switching device can be part of the drive and/or the control unit.

It is also advantageous if the at least one traction means runs at least partially within the guide rail. As a result, a disruptive course of the at least one traction mechanism in the area of the entrance to the goods compartment can be ruled out. In addition, injuries due to the moving at least one traction mechanism can be avoided. Advantageously, the at least one traction mechanism is also guided from the deflection into the guide rail by means of the at least one guide roller.

There are advantages if the at least one traction means is designed as a belt, toothed belt, rope or chain. In this way, a non-positive connection can be increased by means of friction between the at least one deflection roller and/or the at least one guide roller to the traction mechanism. If at least one of the deflection rollers and/or at least one of the guide rollers advantageously also has teeth, a positive connection between the at least one deflection roller and/or the at least one guide roller to the traction means can be ensured if the guide means also has corresponding teeth.

It is also advantageous if the panes each form a composite pane, at least in sections, with at least two individual panes running parallel to one another, with the individual panes of a pane in the edge region of the composite pane being at least partially bonded with the aid of a transparent and/or transparent hardening mass, preferably in the form of, in particular hardened adhesive, are connected.

In particular, it is advantageous if the panes have a rectangular shape, with the individual panes being connected in the region of their horizontally extending end faces with the aid of an adhesive that has hardened transparently during the manufacture of the composite pane. The adhesive adheres to the panes and causes a power transmission between the panes so that they are permanently connected to each other with the help of the adhesive. In the area of the vertically running end faces, the individual panes can also be connected with the mentioned adhesive. However, this is not absolutely necessary since the vertical end faces are preferably guided in the guide mentioned and are therefore not visible from the outside. In the area of the vertical end faces, the individual panes can therefore also be connected with the aid of a non-transparent adhesive. A spacer can also be arranged between the panes in the area mentioned and glued to them, in which spacer there is preferably a drying agent which prevents the inner sides of the pane elements from fogging up.

Preferably, the panes are frameless. In particular when using the described transparently hardened adhesive, the pane surface formed by the panes in their closed position is not interrupted in the vertical direction by any non-transparent elements, so that an optimal view into the interior of the goods compartment is ensured.

Of course, it is conceivable for an edge protection profile to be present, particularly in the area of the horizontally running end faces of the panes, which seals off the panes from the outside. The edge protection profile can consist of a transparent plastic (e.g. it can be in the form of an extruded profile) and be glued to the panes. Partial embedding in the transparently cured adhesive is also conceivable.

In particular, it is advantageous if balancing weights are arranged in the area of the discs. The disks described above can have different masses due to their complexity or due to manufacturing tolerances. In order to equalize the weight forces of the disks in a pair of disks, one or more balancing weights can be arranged in the area of the disks. The balancing weights can be arranged directly on the disks, their connection area to the traction means, or the ends of the traction means leading to the disk. As a result, the balancing of the respective weight forces of the pulleys, which act on the deflection in the intended use of the pulley system, can be guaranteed.

In addition, it is advantageous if the pane system has a support frame which, in addition to the panes, contains the guide arrangement and/or the traction means and/or the deflection and/or the slide-in box (if present) and/or the damping element (if present) and/or the Lighting device (if provided) and/or the drive (if provided) and/or the safety device (if provided) and/or the switching device (if provided) and/or the sensor device (if provided) and/or the control unit (if provided) carries and combines to form a structural unit.

The support frame preferably comprises the guide arrangement, the slide-in box and/or a deflection box in which the deflection is arranged. The components mentioned thus bring about the stability of the unit. The support frame can be designed such that this z. B, can be arranged in front of and connected to a refrigerated display case that is open to the front. In this way, an existing piece of refrigerated furniture can be equipped or retrofitted with the pane system according to the invention.

In general, the supporting frame can serve as a supporting element for one or more further sections of a refrigerated appliance that are connected to the supporting frame. For example, it is conceivable that the support frame is connected to a ceiling unit of the refrigeration appliance and supports it at the bottom. Additional supports for the ceiling unit in the area of the pane system are preferably not provided.

It is also advantageous if the disks are sealed by means of sealing elements, for example magnetic seals, plastic seals and/or brush seals is sealed in its closed position to each other and / or to the guide assembly. The sealing elements bear against at least two disks and/or at least one disk and the guide arrangement. As a result, in the closed position, the goods compartment of the refrigeration appliance can be essentially completely closed off from the outside, at least thermally.

In addition, it is advantageous if the disc system has at least one height compensation element, in particular at least one adjustable foot, on the guide arrangement. The at least one height compensation element is arranged, for example, on the underside of the guide arrangement, in particular on at least one of the guide rails. The pane system or the refrigerated cabinet stands on a base. The at least one height compensation element can compensate for height differences in the substructure between two guide rails and/or between the pane system and a frame structure of the refrigeration appliance.

The pane system can be connected to the frame structure of the refrigeration appliance, in particular mechanically, or can rest against the frame structure or be decoupled from it. Height differences between the frame structure and pane system can also be compensated for by means of the height compensation elements, which means that further interface adjustments are no longer necessary. The pane system can also be arranged on any frame system.

The invention also relates to a piece of refrigerated furniture, which serves to accommodate and present foodstuffs to be cooled, with a goods compartment and a pane system which closes the goods compartment in a closed position. The pane system is designed according to the above description and connected to a frame structure of the refrigeration appliance, it being possible for the features of the pane system mentioned above or below to be present individually or in any combination.

In particular, the refrigerated cabinet can, as explained at the outset, be designed as a conventional refrigerated cabinet with goods shelves and side and rear walls or as a combination of a goods space and a refrigerated space, with the refrigerated space and the goods space being connected by a connection (e.g. wall with roller blind or sliding door(s) ) in order to be able to move goods from the cold room to the goods room.

It is advantageous if a guide arrangement of the pane system is arranged on or connected to a refrigerated cabinet head of the refrigerated cabinet in such a way that the guide arrangement absorbs at least part of the weight of the refrigerated cabinet head and thus serves as a support against lowering of the refrigerated cabinet head (caused by cold deformation).

It is also advantageous if at least one shelf arranged in the goods space, which divides the goods space into individual goods compartments, is arranged on or connected to the guide arrangement of the pane system in such a way that the guide arrangement absorbs at least part of the weight of the at least one shelf and thus serves as a support against lowering of the shelf (caused by cold deformation and/or the weight of the goods). It is conceivable that a simple goods shelf known from the prior art serves as a goods carrier or forms the goods compartments. Such a shelf can be arranged in the goods space and/or at least partially form the goods space.

Finally, the pane system can be connected to the goods shelf or, when used as intended, placed in front of the goods shelf and serves to close a goods space that accommodates the goods shelf at the front, i.e. in the direction of a person who wants to put goods in the goods space or remove them from it when the disc system is in its open position.

a section in the area of a deflection of a disc system according to the invention according to a further embodiment.

figure 1 shows a front view of sections of a refrigeration appliance 1 relevant for understanding the invention with two pane systems 2a, 2b according to the invention arranged next to one another according to an exemplary embodiment. Each of the pane systems 2a, 2b is arranged in front of a base body (not shown) of the refrigeration appliance 1 and has four panes 3a-3d. The discs 3a - 3d are designed as movable discs 3a - 3d. As shown here, the panes 3a - 3d of pane system 2a in a closed position close access to a goods compartment 4 located behind panes 3a-3d in relation to the plane of the page. Panes 3a - 3d of pane system 2b provide access to goods compartment 4 in a illustrated open position free (right pane system 2b) or close the access to goods compartment 4 (left pane system 2a). The goods compartment 4 can be the goods compartment 4 of a refrigerated appliance 1 or of two refrigerated appliances 1 arranged next to one another.

Each of the disk systems 2a, 2b has a guide arrangement with two guide rails 5 each. The discs 3a - 3d are thus guided on both sides in a horizontal direction HR. For this purpose, the two guide rails 5 are essentially spaced apart from one another by a pane width in the horizontal direction HR. In the exemplary embodiment shown, two traction means 6a, 6b each run within the guide rail 5. Each traction device 6a, 6b connects the discs 3a and 3b and the discs 3c and 3d to form a pair of discs. Two first traction means 6a preferably connect the two disks 3a and 3b to form a first pair of disks, and two second traction means 6b connect the two disks 3c and 3d to form a second pair of disks. The respective first traction means 6a of a pair of disks and the respective second traction means 6b of a disk pair are spaced apart from each other by approximately one disk width in the horizontal direction HR. In this way, in addition to guiding on both sides, tilting of the panes can be avoided.

A deflection device 7 is arranged above the respective disk system 2a, 2b. The traction means 6a, 6b are guided over the deflection 7 in such a way that the discs 3a and 3b of the first pair of discs as well as the discs 3c and 3d of the second pair of discs are each on different sides of the deflection 7. As a result, the first disk 3a of the first pair of disks and the first disk 3c of the second pair of disks move in a first direction of movement BR1. The second disk 3b of the first pair of disks and the second disk 3d of the second pair of disks move simultaneously in a second direction of movement BR2 that is essentially opposite to the first direction of movement BR1.

Since the pane system 2a is in the closed position and the pane system 2b is in the open position, the directions of movement BR1, BR2 possible from the stated positions are opposite to one another. The panes 3a-3d of the pane system 2a in the closed position move away from each other along their respective direction of movement BR1, BR2 when changing to the open position. The panes 3a-3d of the pane system 2b in the closed position move towards one another along their respective direction of movement BR1, BR2 when changing into the closed position.

The panes 3a - 3d are in their closed position, as shown in the case of pane system 2a, lined up next to one another in the area of their respective horizontal end faces or overlap one another slightly. As a result, access to the goods compartment 4 can be completely closed. If the panes 3a - 3d are arranged in their open position, as shown in the case of pane system 2b, then the first panes 3a, 3c and the second panes 3b, 3d are located one behind the other. Due to the different necessary movements of the individual discs 3a - 3d, different movement speeds of the discs 3a - 3d are necessary when moving between the open position and the closed position.

In the following descriptions of the Figures 2 to 4 illustrated embodiments are for features compared to preceding embodiment figure 1 are identical and/or at least comparable in their design and/or mode of operation, the same reference numbers are used. If these are not explained again in detail, their design and/or mode of action corresponds to the design and mode of action of the features already described above.

figure 2 shows a detail in the area of a deflection 7 of a disc system 2b according to the invention in an open position according to an embodiment similar to FIG figure 1 . In the open position shown here, the respective first panes 3a, 3c are one behind the other at their upper end position, ie they overlap. The two second panes 3b, 3d are not shown for the sake of clarity. Here, on the figure 1 referred. To guide the panes 3a, 3c, the two guide rails 5 each have two guide sections 8a, 8b, with the guide section 8a guiding the first pane 3a of the first pair of panes and the guide section 8b guiding the first pane 3c of the second pair of panes. In addition, the second disks 3b, 3d of the respective, in figure 1 shown, disk pairs in the two guide sections 8a, 8b be guided. The respective traction means 6a, 6b also run within these two guide sections 8a, 8b and connect the disks 3a-3d of the respective disk pairs to one another.

The traction means 6a, 6b are each deflected at the deflection 7 arranged above the disks 3a, 3c. In order to ensure a uniform movement, the respective traction means 6a, 6b are arranged on both sides of the discs 3a, 3c in the horizontal direction HR. The sides of the panes 3a-3d that are spaced apart from one another in the horizontal direction HR are referred to below as the pane sides. In order to deflect the respective first traction means 6a, the deflection has a first deflection roller 9a in each case. For deflecting the second traction means 6b, the deflection has a second deflection roller 9b in each case. The respective deflection rollers 9a, 9b are in the same way as the respective traction means 6a, 6b are spaced apart from one another essentially by the width of a disk in the horizontal direction HR. The first discs 3a, 3c of the two pairs of discs are each arranged on the same side of the respective deflection roller 9a, 9b on the traction means 6a, 6b. In the exemplary embodiment shown, the first disk 3a of the first pair of disks is arranged on the rear section of the traction mechanism 6a. The first disk 3c of the second pair of disks is arranged on the rear section of the traction mechanism 6b. The respective other section of the respective traction means 6a, 6b leads to the second discs 3b, 3d (see figure 1 ) of the respective pair of discs.

The two traction devices 6a, 6b on one side of the disc are preferably one to three traction device widths apart in the horizontal direction HR. In the exemplary embodiment shown, the traction means 6a, 6b run essentially directly next to one another. The width of one of the traction devices 6a, 6b in the horizontal direction HR is to be understood as the width of the traction device. Thus, the two deflection rollers 9a, 9b are also arranged directly next to one another.

In order to ensure different movement speeds of the two first discs 3a, 3c of the different pairs of discs, the two deflection rollers 9a, 9b have different diameters from one another. In order to achieve a faster movement speed of the two discs 3a, 3b (see figure 1 ) of the first pair of discs, the first deflection roller 9a has a larger diameter than the second deflection roller 9b. In addition, the two deflection rollers 9a, 9b can have teeth, as shown here, which improves the frictional and/or positive connection to the traction means 6a, 6b. If the traction means 6a, 6b is preferably designed as a toothed belt, these teeth of the toothed belt are in positive engagement with the teeth of the toothed deflection rollers 9a, 9b.

The respective adjacent deflection rollers 9a, 9b on each side of the disk are also directly connected to one another. For example, will the If the first deflection roller 9a is rotated by introducing a movement on a disk 3a, 3b connected via the tension element 6a, the second deflection roller 9b rotates at the same speed. The movements of the two discs 3a, 3b can thus be synchronized due to the toothing of the deflection rollers 9a, 9b. In addition, the deflection 7 has a first connecting shaft 10a. The deflection rollers 9a, 9b on both sides of the disk, which are spaced apart by the width of the disk, are coupled to one another via the first connecting shaft 10a and thus form a rotatable unit.

In order to guide each of the traction devices 6a, 6b in such a way that they run in the respective guide sections 8a, 8b of the guide rails 5, the deflection device 7 has a plurality of guide rollers 11a, 11b. Similar to the deflection rollers 9a, 9b, the guide rollers 11a, 11b also have different diameters. The deflection rollers 11a, 11b, which are spaced apart from one another by the width of the disc, on both disc sides of a disc pair are coupled to one another via a second connecting shaft 10b and thus form a further rotatable unit.

Figure 3a shows a sectional view of a refrigeration appliance 1 with a pane system 2a according to the invention in a closed position according to an alternative embodiment. The discs 3a - 3d close the access to the goods compartment 4 completely. The discs 3a - 3d are shown spaced apart by a gap only for a better illustration. In order to completely close off the access, they can be in abutment against one another or they can overlap one another.

In the exemplary embodiment shown here, the respective disks 3a - 3d of a disk pair are in the same guide section 8a, 8b (see 2 ) guided. The two discs 3a, 3b of the first pair of discs are thus in the closed position of the pane system in the center for access to the goods compartment 4 butt against each other. If the disks 3a, 3b and/or the disks 3c, 3d are in different guide sections 8a, 8b (see 2 ) out, the discs 3a, 3b can overlap in the middle to access the goods compartment 4.

The two discs 3a, 3b are connected to one another as the first pair of discs via two first traction means 6a running one behind the other in the plane of the drawing. The first disk 3a of the first pair of disks is arranged on the rear section and the second disk 3b of the second pair of disks is arranged on the front section of the first traction mechanism 6a. The first traction device 6a is deflected via the first deflection roller 9a in such a way that a movement of the first disc 3a of the first pair of discs in the first direction of movement BR1 leads to a movement of the second disc 3b of the first pair of discs in the second direction of movement BR2. The disks 3c, 3d of the second pair of disks behave in the same way. The movement can be brought about manually by a person standing in front of the disk system 2a, 2b. The two discs 3a, 3b of the first pair of discs each have a handle 12 for this purpose.

The movement directions BR1 and BR2 both run parallel to a vertical direction VR. An angle that is spanned between the vertical direction VR and one of the directions of movement BR1, BR2 is therefore equal to 0°. The weight of the disks 3a-3d thus acts in the second direction of movement BR2 and counter to the first direction of movement BR1. Since two disks 3a-3d are connected to one another as a disk pair via a traction device 6a, 6b, this weight force of the disks 3a, 3b or 3c, 3d connected to a traction device 6a, 6b balances out.

The panes 3a - 3d are, as shown here, designed at least in sections as a composite pane. The pane composite has at least two individual panes running parallel to one another, the individual panes being connected at least in sections in the edge area of the composite pane with the aid of a transparent and/or transparent hardening mass, preferably in the form of a transparently hardened adhesive.

Figure 3b shows a sectional view of a refrigeration appliance 1 with a pane system 2b according to the invention in an open position according to an embodiment similar to FIG Figure 3a . Figure 3b thus essentially shows the refrigerated cabinet 1 of FIG Figure 3a with disks 3a-3d shifted in the respective direction of movement BR1, BR2. The respective discs 3a - 3d of each pair of discs are in the open position at a maximum distance from one another. The access to the goods area 4 is thus open. The guide arrangement with at least one guide rail 5, as in the figures 1 , 2 and 4 shown is not shown for a clearer representation.

The deflection 7 is arranged in a deflection box 13 . In their open position, the first two panes 3a, 3c are arranged at the upper end of the pane system 2a, 2b. For this purpose, the deflection box 13 can identify a receiving area for the first panes 3a, 3c. In their open position, 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 . In the closed position and/or in a position between the closed position and the open position, the cover element 15, as in Figure 3a shown, pivoted in the direction of the goods space 4.

In the area of the slide-in box 14 and in the area of the deflection box 13, a damping element 16 are each arranged, which the movement of the discs 3a - 3d can dampen. Alternatively, 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.

On the front and thus on the side facing away from the goods compartment 4 in the figures 3a and 3b For the refrigeration appliance 1 shown, 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.

In addition, 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.

figure 4 shows a front view of a pane system 2 according to the invention in an open position according to an alternative embodiment. In contrast to the previous exemplary embodiments, only the pane system 2 is shown here. Likewise, the disc system 2 on a base body of the refrigerated cabinet 1, as in the Figures 1 - 3b shown, arranged and subsequently connected to it, for example be. The pane system 2 can therefore also be retrofitted to existing refrigeration units 1 .

In the area of the guide rails 5, 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 .

In addition, the deflection 7, especially in the area of the rotatable unit, as above to the figure 2 described, driven by a drive 18. In particular, 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. For this purpose, 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.

figure 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.

In the previous exemplary embodiments, 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. In contrast, are in the figure 5 shown embodiment, 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 .

Here too, 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. In the exemplary embodiment shown, 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. Thus, 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.

In addition, 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. So that the respective sides of the traction means 6a, 6b can be guided past one another in the horizontal direction HR, the guide rollers 11a, 11b are offset by at least one traction means thickness relative to the guide rollers 11c, 11d. In the exemplary embodiment shown, the thickness of the traction means extends in the horizontal direction HR. Additionally or alternatively, 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.

Here, too, 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. By means of 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. For this example, a drive 18 according to the previous embodiment of the figure 4 find use.

The present invention is not limited to the illustrated and described embodiments. Modifications within the scope of the patent claims are just as possible as a combination of the features, even if they are shown and described in different exemplary embodiments.
