Description

The invention relates to refrigerated sales furniture and methods therefor.
Refrigerated sales furniture having at least one refrigerated sales space may be provided with doors, in particular transparent doors, for closing the refrigerated sales space. When closing the refrigerated sales space, such doors thermally isolate the refrigerated sales space from the environment, in particular reducing the exchange of cold air from the refrigerated sales space with warm ambient air. This minimizes the amount of energy needed for cooling the refrigerated sales space to a desired temperature and thus enhances the energetic efficiency of the refrigerated sales furniture.
DE102014004351 B3 discloses a refrigerated sales furniture having pivoting doors.
Such doors, however, obstruct the access to the refrigerated sales space. This may be inconvenient in situations in which full access to the refrigerated sales is desirable. These situations in particular may include "peak times", i.e. in times in which customers frequently access the refrigerated sales space for taking out products, "goods loading times", in which new products are loaded into the refrigerates sales space, "cleaning times", and "maintenance times".
Accordingly, it is an object of the present invention to provide refrigerated sales furniture combining the advantages of an energy saving configuration in which doors thermally isolate the refrigerated sales space from the environment, with the advantages of a "free access" configuration, in which the access to the refrigerate sales space is not obstructed by doors.
In this context, the technical problem cited previously is solved with the construction of the refrigerated sales furniture according to claim 1.
A further object of the invention is to include a method of providing full access to the refrigerated sales space of refrigerated sales furniture according to claim 1.
A further object of the invention is to include a method of changing the mode of access of the refrigerated sales space of refrigerated sales furniture according to claim 1.
A further object of the invention is to include a method of closing a refrigerated sales space of refrigerated sales furniture according to to claim 1.
An example that is not part of the invention also include a method of accessing the refrigerated sales space by moving at least one door which is mounted to a respective door frame segment from its closed position, in which the door closes the respective part of the refrigerated sales space, into an open position allowing access to the respective part the refrigerated sales space.
The embodiments of the invention allow changing the mode of access to the refrigerated sales space of refrigerated sales furniture easily and conveniently by selectively moving the door frame segments between the planar arrangement and a folded arrangement.
In the planar arrangement, in which the door frame segments extend in the common plane with the front facing of the furniture body, the doors, which are supported by the door frame segments, thermally isolate the refrigerated sales space from the environment. This reduces the power consumption and enhances the efficiency of the refrigerated sales furniture, in particular when the need for access to the refrigerated sales space is low and the doors are opened only occasionally.
On the other hand, exemplary embodiments of the invention allow for an easy and unobstructed access to the refrigerated sales space when the door frame segments are moved into the folded position. Providing unobstructed access to the refrigerated sales space is beneficial in particular during "peak times", "goods loading times", "cleaning times", and "maintenance times"., when the demand for accessing to he refrigerated sales space is high and the doors would be opened frequently.
Thus, exemplary embodiments of the invention provide the advantages of an energy saving configuration in which doors thermally isolate the refrigerated sales space from the environment as well as the advantages of a "free access" configuration in which the access to the refrigerate sales space is not obstructed by any doors.
A number of optional features are set out below. These features may be realized in particular embodiments, alone or in combination with any of the other features.
According to the invention, adjacent door frame segments are pivotally connected to each other. Particularly, two adjacent door frame segments are connected to each other by means of at least one hinge, which is mounted to the edges of adjacent door frame segments. Pivotally connecting adjacent door frame segments allows folding the door frame segments in an accordion type zig-zag-structure.
In one embodiment, the at least one door is pivotally mounted to a corresponding door frame segment. A pivoting door allows accessing the refrigerated sales space conveniently. Door frame segments each supporting a pivoting door may be folded easily.
In another embodiment, the at least two door frame segments can be moved into a folded arrangement in which they are arranged at a side of the furniture body. In case a plurality of furniture bodies is arranged next to each other, the door frame segments may be moved into a position between two adjacent furniture bodies. When arranged in this folded arrangement, the door frame segments allow for unobstructed access to the refrigerated sales space.
According to the invention, the door frame segments, when in the folded arrangement, extend substantially perpendicularly to the common plans. Arranging the door frame segments perpendicularly to the common plans minimizes the obstruction caused by the door frame segments.
In another embodiment, the door frame segments are guided between the planar arrangement and a folded arrangement by means of at least one front guide rail, particularly by an upper front guide rail and/or a lower front guide rail. The at least one front guide rail in particular may extend along the front facing of the furniture body extending between the front portions of the left and right sides of the refrigerated sales furniture. Such front guide rails allow moving the door frame segments easily and safely between the planar arrangement and a folded arrangement. In particular, such front guide rails prevent any movement of the door frame segments in undesired directions, which could be dangerous for the operator.
In another embodiment, each door frame segment has a rectangular shape comprising a top side, a bottom side and two lateral sides extending between the top side and the bottom side, respectively. A first lateral side of each door frame segment is guided by the at least one front guide rail and an opposing second lateral side of each door frame segment is movable in a forward direction, i.e. away from the refrigerated sales space, with respect to the at least one front guide rail. This allows folding the door frame segments in an accordion type zig-zag-structure.
In another embodiment, each door frame segment comprises at least one support pin, particularly an upper support pin and/or a lower support pin. The at least one support pin is guided in a lateral direction by the at least one front guide rail. Support pins provide a reliable connection between the guiderail(s) and the door frame segments.
In another embodiment the at least one support pin is provided with a roller or castor, which is configured for rolling along the respective guiderail. Employing rollers or castors reduces the friction when the support pins move with respect to the front guide rail(s), and thus facilitates the moving of the door frame segments between the planar arrangement and a folded arrangement.
According to the invention, the two laterally adjacent door frame segments are arranged in pairs of door frame segments. Upper and/or lower support pins are arranged at upper / lower left portions of the left door frame segment and at upper / lower right portions of the right door frame segment of each pair of door frame segments, respectively. As a result, the right portion of the left door frame and the left portion of the right door frame fold in a forward direction when moving the pair of door frame segments from the planar to the folded arrangement. Such a configuration allows folding the door frame segments in the accordion type zig-zag-structure.
In another embodiment, one lateral side of at least one of the door frame segments is fixed to the furniture body, in particular to a pillar and/or to a side wall of the refrigerated sales furniture, preventing a lateral movement of the at least one of the door frame segment. Fixing one of the door frame segments to the furniture body allows for a convenient transition between the planar arrangement and a folded arrangement of the door frame segments.
In another embodiment, one of the door frame segments, in particular a door frame segment which is arranged opposite to the door frame segment that is fixed to the furniture body, is lockable to the furniture body, in particular to a pillar and/or to a sidewall of the refrigerated sales furniture, in order to prevent any accidental or unauthorized movement of the door frame segments.
In another embodiment, the door frame segments are movable into a parking position when arranged in a folded arrangement. The door frame segments in particular are movable in a direction towards the rear wall of the refrigerated sales space, i.e. a direction which is perpendicular to the common plane. The refrigerated sales furniture in particular may be a refrigerated cabinet, in which the refrigerated sales space is accessible from the front, or a refrigerated chest, in which the refrigerated sales space is accessible from the top. In consequence, the common plane may be a vertical plane extending in front of the refrigerated sales space of a refrigerated cabinet, or a plane extending on top of the refrigerated sales space of a refrigerated chest. The common plane may extend horizontally or in an inclined orientation.
The door frame segments may be movable into a lateral position adjacent to one of the sides of the refrigerated sales space. The door frame segments in particular may be accommodated in a side portion of the refrigerated sales space or in a separate parking space which is provided next to the refrigerated sales space. A wall may separate said separate parking space from the refrigerated sales space. Moving the door frame segments into such a lateral position improves the access to the refrigerated sales space even further, as the door frame segments do not occupy any space in front of the refrigerated sales furniture.
In another embodiment, at least one of the door frame segments is guided by at least one guide rail extending perpendicularly to the upper and lower front guide rails in order to allow moving the door frame segments in a direction perpendicular to the common plane.
In another embodiment, at least one of the door frame segments is mounted to some kind of carriage, wherein the carriage is particularly movable in a direction which is oriented perpendicularly to the common plane. This facilitates the movement of the door frame segments and in particular avoids an undesired tilting and/or blocking of the door frame segments.
In another embodiment, the carriage is guided by at least one guide rail, extending perpendicularly to the front guide rails in order to allow moving the carriage in a direction which perpendicular to the common plane.
In another embodiment, the carriage is provided with at least one roller or castor in order to reduce the friction when moving the carriage.
In another embodiment, a method according to an exemplary embodiment of the invention includes moving the door frame segments into a parking position by moving the door frame segments in a direction perpendicular to the common plane This movement reduces the space which is occupied by the door frame segments in front of a refrigerated sales cabinet or above a refrigerates chest, and thus improves the access to the refrigerated sales space even further.
In the following, a refrigerated sales cabinet according to an exemplary embodiment of the invention is described in more detail with respect to the enclosed figures.

Figure 11 depicts a detail enlargement of Figure 10.

Figures 1, 3, 4, 6, and 8 depict perspective views of a refrigerated sales cabinet (refrigerated sales furniture) 2 according to an exemplary embodiment of the invention. Figures 2, 5 and 7 depict a horizontal sectional view through a front portion of the refrigerated sales cabinet 2 shown in Figures 1, 4, and 6, respectively.
A refrigerated sales cabinet 2 according to an exemplary embodiment of the invention comprises a furniture body 3 having a base 16, a top portion 18 and a rear wall 4. The rear wall 4 extends vertically between the base 16 and the top portion 18 along the rear side of the furniture body 3. The furniture body 3 further may comprise a left side wall 5 (see Figs. 2, 4, and 5 to 8) and right side wall 7. The side walls 5, 7 are provided at the lateral ends of the furniture body 3 and extend vertically between the base 16 and the top portion 18 of the furniture body 3. In order to allow an unobstructed view into the refrigerated sales cabinet 2, the right side wall 7 is not shown in Figures 1, 3, 4, 6, and 8. In case a plurality of furniture bodies 3 are arranged next to each other, usually only the two outermost furniture bodies 3 are provided with a side wall 5, 7, respectively; and the sides of the furniture bodies 3 facing an adjacent furniture body 3 remain open.
The base 16, the top portion 18, the rear wall 4 and the side walls 5, 7 define a refrigerated sales space 10, which is open to the front. A plurality of horizontally extending shelves 14, which are configured to hold goods to be presented within refrigerated sales space 10, are provided in the refrigerated sales space 10.
Four door frame segments 12a, 12b are provided at the front of the refrigerated sales space 10. The door frame segments 12a, 12b, in combination, constitute a door frame framing the front portion of the refrigerated sales space 10.
Each of the door frame segments 12a, 12b supports a door 8, such that the door 8 is movable, in particular pivotable, between a closed position in which it closes the respective part of the refrigerated sales space 10 (see Figures 1 and 2), and an open position (see Figure 3) in which it allows access to the respective part of the refrigerated sales space 10.
When arranged in their respective closed positions, the doors 8 prevent cold air from flowing out of the refrigerated sales space 10 and warm ambient air from flowing into the refrigerated sales space 10. As a result, the energy needed for cooling the refrigerated sales space 10 to a desired temperature is reduced and the refrigerated sales cabinet 2 may be operated more efficiently.
However, since the doors 8 may be seen as an obstacle for customers wanting to access the refrigerated sales space, it may be desirable to provide full and unobstructed access to the refrigerated sales space, for example during "peak times", i.e. in times when customers frequently access the refrigerated sales space 10 for taking out products.
According to the invention, the door frame segments 12a, 12b are movable between a planar arrangement, in which the door frame segments 12a, 12b extend in a common upright plane with the front facing of the furniture body 3 between the left and right sides or side walls 5, 7, and at least one folded arrangement, in which the segments extend substantially perpendicularly to said common plane. Examples of partially folded arrangements of the door frame segments 12a, 12b are shown in Figures 4 and 5, and Figures 6 to 8 depict completely folded arrangements of the door frame segments 12a, 12b.
In order to allow the door frame segments 12a, 12b to be moved between the planar arrangement and at least one folded arrangement, adjacent door frame segments 12a, 12b are pivotally connected with each other. Two adjacent door frame segments 12a, 12b in particular are connected with each other by at least one hinge 9. Each hinge 9 allows the adjacent door frame segments 12a, 12b to pivot with respect to each other around a vertical axis extending parallel to the rear wall 4 of the furniture body 3. Such a configuration allows folding the door frame segments 12a, 12b in an accordion type zig-zag-structure, as it is illustrated in Figures 4 and 5.
The door frame segments 12a, 12b are arranged in pairs of left and right door frame segments 12a, 12b, wherein a right portion of each left door frame segment 12a and a left portion of each right door frame segment 12b move in a forward direction, i.e. away from the refrigerated sales space 10, when the door frame segments 12a, 12b are moved from the planar arrangement (see Figures 1 and 2) into the folded arrangement (see Figures 4 and 5).
In the configuration shown in the figures, the rightmost door frame segment 12b which is located next to the right side or side wall 7 is fixated to the furniture bodv 3 so that it may pivot around a vertical axis but cannot move (shift) in the lateral direction.
At least one of the other door frame segments 12a, 12b, in particular the leftmost door frame segment 12a, may be lockable to the furniture body 3, in particular to the left sidewall 5 of the furniture body 3. The at least one lockable door frame segment 12a, 12b may be locked to the furniture body 3 when the door frame segments 12a, 12b are arranged in their planar arrangement in order to avoid that the door frame segments 12a, 12b move from the planar arrangement into a folded arrangement accidentally and/or without authorization.
A lock (not shown) for locking the at least one lockable door frame segment 12a, 12b may be located within at least one of the upper and lower front guide rails 20, 22.
In an alternative configuration which is not shown in the figures, the leftmost door frame segment 12a, which is arranged next to the left side or side wall 5, may be fixed to the furniture body 3, in particular to the left side or side wall 5 of the furniture body 3, and the rightmost door frame segment 12b may be lockable to the furniture body 3, in particular to the right side or side wall 7 of the furniture body 3.
The skilled person will understand that not only one of door frame segments 12a, 12b may be lockable, but that a locking function may be provided for any of the door frame segments 12a, 12b.
The door frame segments 12a, 12b may be moved into a completely folded arrangement as illustrated in Figures 6 and 7. In the completely folded arrangement, the door frame segments 12a, 12b are arranged side by side parallel to each other at one side of the furniture body 3, particularly adjacent to one of the left and right sides or side walls 5, 7. According to the invention, the door frame segments extend substantially parallel to the sides or side walls 5, 7 and perpendicular to the common plane. When arranged in the completely folded configuration, the door frame segments 12a, 12b provide free access to the refrigerated sales space 10.
When moved between the planar arrangement and a folded arrangement, the door frame segments 12a, 12b are guided bv an upper front guide rail 20 and a lower front guide rail 22. The upper front guide rail 20 is located at the top of the refrigerated sales space 10 below the top portion 18 of the furniture body 3 and extends horizontally between the left and right sides. The lower front guide rail 22 is located on top of the base portion 16 of the furniture body 3 at the bottom of the refrigerated sales space 10 and extends horizontally between the left and right sides.
The upper front guide rail 20 and the lower front guide rail 22 in particular may be mounted to the lower side of the top portion 18 and to the upper side of the base portion 16 of the furniture body 3, respectively.
In each pair of door frame segments 12a, 12b comprising a left door frame segment 12a and a right door frame segment 12b, the left portion of the left door frame segment 12a and the right portion of the right door frame segment 12b are guided by the front guide rails 20, 22, while the opposing sides of each door frame segments 12a, 12b are movable in a front direction as described before with reference to Figures 4 and 5.
Figure 9 shows a vertical sectional view through a front portion of the refrigerated sales furniture 2 including a door frame segment 12a along line A-A depicted in Figure 2.
Figure 9 in particular depicts a door frame segment 12a with a door 8 and the upper and lower front guide rails 20, 22 which are mounted to the base portion 16 and to the top portion 18 of the furniture body 3, respectively. The refrigerated sales space 10 is located on the left side of Figure 9.
The door frame segment 12a is guided by means of upper and lower rollers or castors 26, 28along the front guide rails 20, 22 extending perpendicular to the plane of view of Figure 9. The rollers or castors 26, 28 are mounted to the door frame segment 12a by means of an upper support pin 34 and a lower support pin 36, respectively.
The door 8 comprises a glass frame 32 supporting a glass pane 30, in particular a glass pane 30 made of thermally insulating glass or acrylic glass. The glass frame 32 is pivotally supported by upper and lower hinges 38, 40 mounted to the door frame segment 12a. The upper and lower hinges 38, 40 are configured to allow opening the door 8 by pivoting the glass frame 32 together with the glass pane 30 with respect to the door frame segment 12a as illustrated in Figure 3.
A combination of magnetic/metallic elements 33 may be attached to the glass frame 23 and to the door frame segment 12a in order to hold the door 8 in a closed position. In an alternative embodiment, special hinges may be employed for locking the doors 8 in their respective closed positions within the door frame segments 12a, 12b, 12c, 12d.
When the door frame segments 12a, 12b are arranged in the completely folded arrangement next to one of the sides of the furniture body 3 (see Figures 6 and 7), the door frame segments 12a, 12b may be moved into a parking position by moving the door frame segments 12a, 12b to the rear, i.e. in a direction towards the rear wall 4 of the furniture body 3. The door frame segments 12a, 12b in particular may be moved into a parking position within or next to the refrigerated sales space 10 in a direction perpendicular to the common plane.
A configuration in which the door frame segments 12a, 12b have been moved into a parking position is illustrated in Figure 8. Moving the door frame segments 12a, 12b into such a parking position, in particular in a position in which the door frame segments 12a, 12b are arranged within or laterally adjacent to the refrigerated sales space 10, avoids that the folded door frame segments 12a, 12b occupy space in front of the refrigerated sales cabinet 2 and obstruct the access to the refrigerated sales space 10.
Figure 10 depicts an enlarged perspective view of lower portions of the door frame segments 12a, 12b arranged in the completely folded arrangement next to the right side of the furniture body 3 (cf. Figure 8), and Figure 11 depicts a detail enlargement of Figure 10.
A plurality of rear guide rails 24 extend perpendicular to the upper and lower front guide rails 20, 22 in order to allow moving the door frame segments 12a, 12b in a direction perpendicular to the common plane.
The rear guide rails 24 are shown at the bottom of the refrigerated sales space 10 in Figures 10 and 11. They, however, may be provided at the bottom and/or at the top of the refrigerated sales space 10, as depicted in Figures 1, 3, 4, 6, and 8.
At least on of the door frame segments 12a, 12b, in particular the rightmost door frame segment 12b, may be supported by a carriage 42 which is guided by at least one of the rear guide rails 24. Employing a carriage 42 allows moving the door frame segments 12a, 12b smoothly. Using a carriage 42 in particular reduces the risk that a door frame segment 12a, 12b tilts and locks, in particular when transferring from the lateral front guide rails 20, 22 to the rear guide rails 24 and vice versa.
In order to reduce the friction when moving the carriage 42 along the rear guide rails 24, the carriage 42 may be provided with at least one roller or castor 44.
Although four door frame segments 12a, 12b and doors 8 are shown in the figures, the skilled person will understand that exemplary embodiments of the invention are not restricted to respective configurations. Instead, the number of door frame segments 12a, 12b and doors 8 may be chosen arbitrarily according to the actual needs, in particular depending on the width of the refrigerated sales cabinet 2.
At least some components of a refrigeration circuit (not shown), in particular at least one evaporator, may be provided within the base 16 and/or the rear wall 4 of the furniture body 3 in order to cool the refrigerated sales space 10 to a desired temperature.
The refrigerated sales cabinet 2 may be a stand-alone refrigerated sales cabinet 2, comprising a complete refrigeration circuit including at least one compressor, at least one condenser, at least one expansion device and at least one evaporator. Alternatively, only at least one expansion device and at least one evaporator may be provided within the refrigerated sales cabinet 2, while the other components of the refrigeration circuit are located in another part of the building, in particular in a separate machine room. A condenser of the refrigeration circuit may be provided outside the building, e.g. on the roof of the building, in order to allow for an efficient transfer of heat to ambient air.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the appended
