Abstract

Description

The invention relates to a goods presenter with a goods space which is separated from the surroundings to the surroundings by a separating device for separating a room, preferably a temperature-controlled room, which is particularly suitable and intended for the presentation and / or storage of the goods, and with a frame carrying the separating device, wherein the separating device comprises an open and closable separating sheet which, against a counterforce, moves from a separating position, in which it separates the space from the surroundings, to an access position, in which the space is accessible from the surroundings is to be moved manually and can be brought from the access position to the separation position by the counterforce. Furthermore, the invention relates to a method for separating and making accessible a room, preferably a temperature-controlled room, which is particularly suitable and intended for the presentation and / or storage of the goods, with an openable and closable partition of a partition against a counterforce of a separation position, in which it separates the room from the surroundings, into an access position in which the room is accessible from the surroundings, manually brought and brought from the access position into the separation position by the counterforce.

Generic merchandise presenters and separating methods are known from the prior art. By means of such goods presenters or separation processes, goods, mostly food, are presented or temporarily stored in a way that is shielded from the environment. To make these goods accessible, a goods cover or a separating disk, which is mostly transparent, can be temporarily created on the side, preferably pushed or lifted, this separating disk being mounted linearly or rotatably with a guide. After the goods have been removed, the cutting disc can then be moved back to its original warehouse.

This shifting back can in particular take place manually, for example from the DE 133 871 A famous. In this embodiment, a drawer of a showcase and a cover of a showcase are connected to each other in such a way that when the showcase is opened and closed, the drawer and cover have linear movements in opposite vertical directions of movement and, with regard to raising and lowering of the drawer or cover, opposite, approximately equalizing movements Have weight effects on movement. It is true that in this case, for example, an unintentional falling down, in particular the cover, can be avoided, as a result of which the risk of injury to the operator or a customer is reduced. However, due to the approximately equal weight effect, the drawer and lid remain in their manually moved positions, so that the display case remains open even if the drawer has already been accessed or no access to the drawer is required. Something similar happens when doors are used to separate the room, since the doors, because of their essentially vertical axis of rotation, also remain in their position when they are not moved manually, that is to say opened or closed.

On the other hand, it is well known. To provide doors with springs or other self-closing mechanisms or even with motorized drives to enable automatic opening or closing, which, however, complicates the operation due to the movements that then take place, because doors then have to be opened manually, for example, or there is a risk of injury . The same applies if the separating disks of the separating device are designed, for example, as flaps which - naturally - can be opened against the force of gravity and then automatically close again due to the force of gravity. This also means that customers or operating personnel have to keep the flaps open if they do not fold down again while accessing the goods and are therefore intended to hinder access.

It is the object of the present invention to make access for a customer to goods through a separating device more reliable and yet simpler.

The object of the invention is achieved by merchandise presenters and separating methods with the features of the independent claims. Further advantageous configurations, possibly also independent of this, can be found in the subclaims and the following description.

The invention is based on the common knowledge that in a merchandise presenter or in a separating method in which an open and closable separating disk enl against a separating force from a separating position from which it separates a space separated from it from the bypass, into a Access position in which the room is accessible from the environment, moved manually and can be brought from the access position into the separating position by the counterforce, the counterforce should be controlled in a suitable manner in order to ensure more reliable access for customers to goods through the separating device and still easier to design. In this case, it is particularly advantageous if a defined closing process is operationally reliable, with which the separating disk which can be opened and closed from its Access position is spent in their separation position, can be guaranteed.

In particular, access for a customer to goods through a separating device can be made more reliable and yet easier if a goods presenter has a goods space that is separated by the separating device for separating a room from the surroundings from the surroundings, and with a separating device load-bearing frame, the separating device comprising an openable and closable separating pane, which is manually moved against a counterforce from a separating position in which it separates the space from the surroundings into an access position in which the space is accessible from the surroundings and can be brought from the access position into the separating position by the counterforce, is characterized in that control means for controlling the counterforce from the openable and closable separating pane at least through another wall of the goods presenter and / or at least by 2 cm and / or at least around three times the strength of the open - and closable separating sheets are spaced apart from the goods space and / or thermally insulated from the goods space. By separating the control means for controlling the counterforce from the openable and closable partition by at least one further wall of the merchandise presenter, harmful influences, which could also negatively affect the control means from the room, such as dirt or thermal influences, can be caused by the control means be kept as far away as possible so that they can work reliably under as many operating conditions as possible. The latter also applies in particular if the control means of the open and closable partition are at least 2 cm or at least three times the thickness of the open and closable partition from the goods space, although much larger distances can certainly be provided if these appears technically sensible and reasonably inexpensive to implement. While even a distance ultimately has a thermally insulating effect, the control means can cumulatively or alternatively be thermally insulated from the goods space in any way in order to ensure that these control means work reliably, which accordingly reduces the influence of any temperature fluctuations when using springs or dampers, for example. that can occur in the separated room, minimized to the control means.

Cumulatively or alternatively, a goods presenter can have a goods space that is separated by a partition device for separating a space from the surroundings to the surroundings, and with a frame carrying the partition device, in which the partition device comprises an openable and closable partition. which, against a counterforce, can be moved manually from a separating position in which it separates the room from the surroundings into an access position in which the room is accessible from the surroundings and can be brought into the separating position by the counterforce of the access position, thereby distinguish that control means for controlling the counterforce are arranged outside the separating device. Arranging the control means outside the separating device also ensures that any influence on the control means emanating from the separated space can be reduced to a minimum, so that access for a customer to goods through the separating device can be designed to be operationally reliable and yet simpler.

Access for a customer to goods through the separating device of a watrenpresenter with a goods space which is separated from the separating device for separating a room from the surroundings to the surroundings, and with a frame carrying the separating device can cumulatively or alternatively be more reliable and yet Make it easier if the separating device comprises an openable and closable separating blade, which moves from a separating position, in which it separates the room from the surroundings, into an access position against a counterforce. in which the room is accessible from the environment, can be moved manually and can be brought from the access position to the separating position by the counterforce, and if the goods presenter is characterized by the fact that control means for controlling the counterforce inside the openable and closable partition a time window of at least 3 s, preferably 4 s, in particular 12 s, and a maximum of 40 s from their access position to their separation position. At such a speed, it can be assumed that the partition, even if it is larger and heavier, does not close so quickly that there is a noticeable risk of injury and, on the other hand, that it closes sufficiently quickly that people who happen to pass the corresponding goods presenter in perceive movement sufficiently to be able to evade it accordingly. This, too, in a relatively structurally simple manner, with a suitable configuration, makes access for a customer to goods through the separating device appear more reliable.

Accordingly, customer access to goods through a separating device can be designed to be operationally reliable and yet simple. when there is a method for separating and making accessible a room, in which an openable and closable partition pane of a partition device against a counterforce from a Separation position, in which it separates the room from the environment, into an access position in which the room is accessible from the environment, manually brought and brought from the access position to the separation position by the counterforce, characterized in that the opening and closable separating pane is moved from its access position to its separating position within a time window of at least 3 s, preferably 4 s, in particular 12 s, and a maximum of 40 s. As already explained above, a corresponding time window appears advantageous for the reasons already explained in the preceding paragraph.

Alternatively or cumulatively to this, a goods presenter can have a goods space that is separated by a partition device for separating a space from the surroundings to the surroundings, and with a frame carrying the partition device, the partition device comprising an openable and closable partition which against a counterforce from a separating position, in which it separates the room from the environment, into an access position in which the room is accessible from the environment, can be moved manually and can be brought from the access position into the separating position by the counterforce. characterized in that control means for controlling the counterforce open and close the separating disk with an angular velocity (m) greater than 0.039 rad / s and / or less than 1.047 rad / s, in particular less than 0.785 rad / s, preferably 0.262 rad / s, from its Can spend access position in their separating position in order to make customer access to goods through a separating device operationally reliable and yet simple. At such angular speeds, the lower limit ensures that the openable and closable partition does not close so slowly that this movement is not recognized by customers or other people, which accordingly prevents unpleasant encounters with the respective partition, while with regard to the upper one The limit of the movement is also not so fast that the impulse inherent in the opening and closing partition when closing leads to considerable injuries if contact is made nonetheless. In a suitable embodiment, access for a customer to goods through a separating device can thus be configured in an operationally reliable and simple manner.

Accordingly, also enables a method for separating and making accessible a room, in which an openable and closable partition pane of a partition device enl against an opposing force from a partition position, in which it separates the room from the environment, into an access position, in which the room from the environment is accessible, moved manually and brought from the access position to the separating position by the counterforce and which is characterized by the fact that the separating disk can be opened and closed with an angular velocity (m) greater than 0.039 rad / s and / or less than 1.047 rad / s, in particular less than 0.785 rad / s, preferably 0.262 rad / s. is moved from its access position to its separating position in order to make access for a customer to goods through the separating device more reliable and yet simpler, which, especially with a suitable design, also brings specific advantages, as already explained in the preceding paragraph.

The term “goods presenter” describes any device by means of which goods can be presented or stored, such as shelves, displays, counters, thrones or the like. Corresponding cabinets, such as refrigerators or warming cabinets, also fall under the term “goods presenter”. Such goods presenters usually include a space for the presentation or storage of goods, which can also be referred to as a goods room.

In addition to the functionality of the goods room, according to which it is used for the presentation and / or storage of goods, a goods room can also be defined as the space that is surrounded by the structural boundaries, such as the rope walls, a cover wall or a frame The goods presenter is delimited and serves this functionality. In this case, however, it is often the case that the goods on offer are only to be found in a sub-area of the goods space, since, for example, maximum filling heights, the opening of ventilation holes or similar marginal ridges still need to be taken into account, although, for example, side walls or other assemblies supporting structures are the per se make the space made available for goods by the goods presenter appear much larger.

Accordingly, it is conceivable that the space separated by the separating device is designed to be smaller than the goods space, in particular if only a partial space of the goods space is to be separated from the separating device. In such configurations, in particular the openable and closable separating disk or also another separating disk, for example a stationary separating disk, can be located within the goods space and undertake the corresponding separation.

On the other hand, it goes without saying that the separating device or the separating disk or the separating disks can be provided at the boundary of the goods space.

Furthermore, it is not absolutely necessary for the separating device to completely separate the space separated from the surrounding area. Rather, the separating device can, for example, also leave open areas that still allow free access to the goods room or the separated room, which can be provided, for example, on an operator's side or staff ropes of a corresponding goods presenter if the staff has constant access shall be. The separating device can then be used, for example, less for thermal isolation than a targeted deflection of any thermal currents, or merely as a spit guard, and can then - if required - be opened by a customer.

Often, temperature-sensitive goods are offered in a goods presenter, so that the goods room or the separated room are preferably also temperature-controlled, which, however, can also be correspondingly advantageous for goods that are only to be kept at a certain temperature. In the present case, a temperature-controlled room is understood to mean any room of a goods presenter, that is to say the goods room or a sub-room thereof, which is or can be specifically kept at a temperature deviating from the ambient temperature. It goes without saying that a corresponding temperature control does not have to be carried out in all cases, for example if the ambient temperature does not seem to be absolutely necessary, as long as a corresponding temperature control can be achieved with the devices provided on the goods presenter at the given time or under given circumstances .

It goes without saying that such temperature control can take place both in the direction of higher temperatures and in the direction of lower temperatures. In particular, hot goods or chilled goods can be offered in the temperature-controlled room.

Depending on the specific application, the separating device is then also designed accordingly. Thus, in the case of smaller temperature differences and high access numbers, the separating device can easily be designed to be less rigid, since any thermal losses are then inevitable or not too high anyway. In these cases in particular, it can be sufficient if the separating device is used, for example, only as a spit guard.

On the other hand, it goes without saying that the separating devices can be used, for example, as supplementary insulation, in particular, for example, as a night cover or, in the case of supplementary thermal insulation, for associated energy savings. In such cases it is advantageous if the separating devices are designed to be correspondingly more rigid in their mode of operation.

A goods presenter is primarily used for the presentation and / or storage of goods, whereby - as the name suggests - the presentation is usually in the foreground. With such a presentation, it is advantageous if the goods are presented in a clearly visible manner, if possible with high product pressure, that is to say with a high incentive to buy or with a high incentive to bring them into possession. This has the consequence that, in particular, cutting disks or other assemblies of the cutting device are often designed to be transparent or also mirrored, which is already sufficiently known from the prior art. On the other hand, it goes without saying that - if this appears sensible - the separating disks of the separating devices, but also other assemblies which are used to delimit the goods space or the separated space, can be designed to be opaque. The latter applies in particular to rear walls, for example, if no access from the customer side is intended. This can also relate, for example, to shelves and the like, in which case transparent arrangements can also be advantageous here.

Goods presenters are usually on the floor or attached to the walls of a building. For reasons of stability, the goods presenter here comprise a frame, with each structural unit of the goods presenter being referred to as a “frame” in the present context, which guarantees the structural integrity of the goods presenter and its assemblies. The frame does not include structures that are then carried by the frame, such as tubs or shelves of goods that are held on separate and removable assemblies on the goods presenter.

Accordingly, a frame carrying the separating device is then at least the assembly of the frame or the assemblies of the frame, which are used to position the separating device or at least one of its assemblies with respect to the remaining assemblies of the goods presenter in the intended structural integrity.

In the present case, the term “separating device” describes any device by means of which a preferably temperature-controlled room can be spatially separated from an environment. The temperature of the environment can either be changed or, if necessary, the temperature can even be actively controlled.

The separating device preferably has transparent viewing elements such as for example Separating discs made of glass or the like. so that goods held in a room are clearly visible outside the goods presenter.

The separating device can in particular also comprise stationary separating disks which are stationary in the normal operating state, that is to say in the operating state in which the goods are presented. In addition, as already explained above, the separating device has at least one openable and closable separating disk, so that access to the space separated by the separating device is possible through the opening, which can be closed by the opening and closing separating disk.

It is understood that - as already indicated above - the separating device does not have to be able to be closed all around if it does not appear to be absolutely necessary under the given circumstances. A separating device can therefore already be present if access to a defined space of the goods presenter cannot take place unhindered from one direction.

Access can then take place, for example, around a stationary cutting disc. It is also conceivable that access can take place through an access opening which can be closed by the separating pane that can be opened and closed.

In particular, it is advantageous if the separating device comprises at least one stationary separating disk in addition to the open and closable separating disks. This enables a more comprehensive separation if this appears sensible for thermal or other reasons. In particular, for example, the open and closable separating disk can then be brought under or over a stationary separating disk, so that it only takes up insignificant space when it is open. In particular, this also ensures that the risk of injury is minimized.

As already explained above, the control means can be spaced from the open and closable partition at least by a further wall of the goods presenter, whereby the control means can be protected from soiling or from thermal stress or from similar stresses.

In the present context, the term “wall” refers to any assembly of the goods presenter that extends into a surface, whereby such a wall can be part of the frame on the one hand and therefore be important because of the structural integrity, or on the other hand part of a cladding without a load-bearing or stabilizing function can be. In particular, the stationary separating disk or one of the stationary separating strips of the separating device can serve as such walls, which structurally enables the control means to be spatially separated quickly and easily from the space separated by the separating device or from the goods space.

In particular, this can also easily ensure that the control means are arranged outside the separating device or are thermally insulated from the space separated by the separating device.

As a separating disk, whether it is openable and closable or stationary, is understood in the present case to be any wall of the separating device, insofar as this wall is provided by a flat assembly. Here, the cutting disk can also be curved or have a relatively complex structure. In particular, however, the separating disk can be designed to be flat, which is structurally simpler to implement. In addition, it goes without saying that the separating disk, as already explained above with regard to the separating device, can be designed to be transparent or opaque. In particular, the separating disk can be made reflective, for example to increase the product pressure, in which case the reflective coating will usually be found on the side of the space separated by the separating device.

An openable and closable partition which can close an access opening or a goods room access comprises - naturally - a partitioning position in which it fulfills its separating function as part of a partitioning device, and an access position in which the openable and closable partition is sufficiently opened is so that the space, which is separated from the environment by means of the associated separating device, is accessible from the environment through the access opening.

Accordingly, the “separation position” refers to any position in which the openable and closable partition panel separates the space from the environment in accordance with the task of the partition device. Depending on the specific implementation, this can be an airtight separation. However, smaller cracks or openings can also remain if these are in the light of the rest of the separating device or in the light of the measure. in which the room is to be partitioned off seems sufficient. In particular, can. if the separation is only to take place in the form of a spit guard or the like, a corresponding separating device which is very little rigid can also be provided so that the separating position denotes the position in which a adequate spit protection or the like is guaranteed.

Deviating from this, the access position is to be defined in which the space is accessible from the surroundings, and this in particular through the access opening that can be closed by the partition that can be opened and closed. Here, the term “access opening” denotes the respective room window which the openable and closable partition pane occupies in its separating position and which ultimately prevents access through the access opening in the separating position.

Access for a customer to goods through the separating device can be designed to be operationally reliable and simple if the counterforce or at least part of the counterforce is or is provided by gravity. To the extent that gravity is used as a counterforce, additional assemblies that provide such a counterforce can be dispensed with. This first of all contributes to a considerable extent to a simplified structure of the goods presenter or to a simple process management, since fewer assemblies are then required. In addition, gravity is to be found in all assemblies that have a mass, so that it should be taken into account in the design anyway.

It goes without saying, however, that additional assemblies, such as, for example, spring elements or damper elements or even motor drives and the like, can be used to provide the counterforce and possibly also to be able to control it as a control means. For example, electric motor but also pneumatic or hydraulic drives can be used as motor drives. depending on the specific implementation, these can be provided with a servo function to support a manual process, such as manual lifting. The counterforce can also be applied by one or this drive when the cutting disk is to be moved from the access position to the cutting position.

Accordingly, it is advantageous if only part of the counterforce is or is provided by gravity, while other components can then be provided by supplementary assemblies which can exert a force on the openable and closable separating window.

It goes without saying that the control means, i.e. the assemblies, which act in addition to the force of gravity with a force on the openable and closable partition and thus contribute to the counterforce, can serve as control means to control the counterforce, since here the influences of the Gravity, which is ultimately provided by the sequence of movements and the geometric relationships, can be controlled. In this case, these components of the counterforce can act in the direction of gravity if its influence is to be increased, or act against gravity if the influence of gravity is to be counteracted.

The latter appears to be particularly useful when the separating pane that can be opened and closed is relatively heavy. so that it is easier for a customer to manually counteract the counterforce in order to open the openable and closable partition.

If, on the other hand, the influence of gravity is relatively small, for example in the case of extremely flat guideways or with an almost hanging, openable and closable partition, the control means can be used to increase the influence of gravity or to provide a significant counterforce in the first place.

It goes without saying that at least the force of gravity acting on the openable and closable partition can be used advantageously in this regard. On the other hand, other assemblies, such as lowerable counterweights or similar, can also provide forces. which are caused by gravity.

As already explained above, the counterforce is designed to move the openable and closable partition pane from the access position to the partition position. By means of a suitable control of the counterforce, for which the control means are used in particular, the counterforce can be controlled in such a way that, in particular, the time specifications or angular speeds explained above can be achieved.

The counterforce is preferably designed in such a way that the openable and closable separating pane can be moved manually from the separating position into the access position. In this way, a customer can gain immediate and direct access to the separated room if this appears necessary to him.

In weighing the average strengths of those people. who are the target customer group of the goods presenter, the counterforce is preferably selected in such a way that they can easily move the openable and closable partition pane manually into the access position.

Because a customer can manually move the openable and closable partition from the partition to the access position, it is up to the customer to decide at what speed he opens the openable and closable partition, which is particularly technical with regard to a motorized application of the opposing forces only appears to be very difficult to implement. In particular, openable and closable dividing panes which open automatically cannot meet this requirement either, since a customer then has to wait until a corresponding motor has brought the openable and closable dividing pane into the access position. This is often unbearable, especially for impatient customers. so that they intervene in the movement process. which in turn reduces operational safety and places very high structural demands on the engine and the associated gearbox.

Because a customer can manually move the openable and closable partition into the access position, it is also possible, in particular, for him to intervene in the closing process without further ado if he nevertheless wants access to the separated room while it is being closed.

With regard to the opposing forces, it should be noted that these generally also accelerate the openable and closable partition pane in every position between the partition position and the access position, including these positions, in the direction of the partition position. In this way, a closing process can be reliably guaranteed by the counterforce.

In the present case, a temperature-controlled room is in particular a room within the goods presenter, for example also the goods room, which can be tempered with the help of an actively operated temperature control device, such as a cooling device, but also a heating device. In particular, easily perishable goods or goods that are to be presented at a certain temperature can be presented or stored for the customer by means of a goods presenter which includes a temperature-controlled space. Such temperature control possibilities are well known per se from the prior art.

Furthermore, it should be pointed out that in the present case, indefinite articles and indefinite number entries such as “one”, “two”, etc. should generally be understood as minimum information, ie as “at least one”, “at least two” etc., provided that it does not emerge from the context or from the concrete text of a certain passage that only "exactly one", "exactly two" etc. should be meant there.

Any devices with which it is possible to control a counterforce that always acts on the openable and closable separating disk can be used as "control means", possibly also depending on the position of the openable and closable separating disk between the separating position and the access position ₊

In particular, such control means can include motorized drives or servomotors.

However, the control means are preferably designed mechanically, which enables a particularly reliable and simple construction of the control means.

In this context, it should be mentioned that mechanical control means are generally susceptible to contamination or thermal loads and the like. By separating the mechanical control means from the separated space or from the goods space, through the thermal insulation of the control means, in particular from the goods space or the separated space, but also, if necessary, from other heat or cold sources. and / or by arranging the control means outside the separating device, such influences, in particular on mechanical control means, can be reduced to a minimum. This in turn results in an increase in operational reliability with a relatively simple structure.

In particular, damper elements or spring elements come into consideration as mechanically designed control means. Depending on the specific configuration, the sensitivities of damper elements and spring elements can be extremely serious as a function of the temperature and the behavior of such elements can be permanently variable. It is precisely for this reason that the above delimitations of the control means compared to thermal stress and similar influences are advantageous.

Oil pressure dampers or gas pressure dampers, for example, can be used as the damper element, with oil pressure dampers and gas pressure dampers in particular being subject to relatively high temperature sensitivity, since, among other things, the viscosity of gases and oils is relatively temperature-dependent, which makes targeted control of the counterforce difficult if it is as independent of temperature as possible so that it should be reproducible.

In particular, gas pressure springs can also be used as spring elements, the influence of temperature being relatively strong here too, so that the above The measures explained can also be used particularly advantageously here.

In particular, the control means can be operatively connected to the openable and closable partition by means of a linkage and / or a lever arrangement. By means of a linkage or a lever arrangement, it is relatively easy to provide a distance between the openable and closable partition and the control means to the desired extent. This also applies in particular with regard to the penetration of thermal insulation or another wall of the goods presenter. For example, axes of rotation, plungers or the like can be used. which represent parts of the linkage or a lever arrangement, such a passage or such a distance are used.

In addition, the force relationships between the control means and the openable and closable partition can be influenced by a linkage and / or a lever arrangement, so that the control means can be constructed in a relatively simple way, for example as linearly acting damper elements or spring elements for position-dependent control then to be able to guarantee via the linkage and / or the lever arrangement.

As already explained above, a distance of 2 cm can already lead to an advantageous relief of the control means. In this respect, it is particularly advantageous if the distance between the control means and the openable and closable partition is at least 3 cm, in particular 4 cm, in order to be able to utilize this effect in a special way.

Accordingly, it is advantageous if the distance between the control means and the openable and closable partition is at least three times the thickness of the openable and closable partition, as already explained above. In particular, it is advantageous if this distance is at least three and a half times the thickness, preferably even four times the thickness, of the separating disk that can be opened and closed. This also helps to separate the control means from any influences that are present in the space separated by the openable and closable partition or in the goods space.

The advantages of thermal insulation of the control means have also been explained above. Such thermal insulation can have an isolating effect, in particular from the openable and closable partition, from the partition device, from the goods space or from the separated space, in order to protect the control means accordingly. Any measures that serve to provide thermal insulation can accordingly also be referred to and used as thermal insulation. In particular, only measures that keep a distance or walls without a load-bearing function can be referred to as thermal insulation, insofar as they can correspondingly reduce the thermal influences acting on the control means.

In particular, the control means can be arranged outside the separating device, which - as already indicated above - can be implemented specifically by the linkage and / or the lever arrangement.

It is particularly advantageous here if the control means are arranged outside the space separated by the separating device and particularly preferably outside the goods space. It depends in particular on the definition of the space that is separated from the separating device, from which point “outside” can be used. Such an “outside” of the separating device is usually already present when the control means are to be found in the surroundings of the separated room set out above. Ultimately, this does not necessarily have to be outside the goods space, which, however, appears to be advantageous for the reasons already explained above of thermal protection or protection against soiling and the like.

In particular, the control means can be arranged below the separating device, since there is usually sufficient installation space here and the appearance of the goods presenter is not burdened too much with unsightly structural assemblies.

The control means are preferably arranged below the goods space. which accordingly relieves the visual appearance, with a merchandise presenter usually leaving enough space there to be able to provide control means.

Such an arrangement “below the goods space” then also includes an arrangement below a goods floor delimiting the goods space downward.

In particular, the separating device can comprise a holding device which holds or can hold the separating disk in its access position against the counterforce and which has a timer to release the separating disk again after a previously defined holding line or to move it towards the separating position, and / or with a presence sensor to release the cutting disc again or in the direction of the cutting position spend when no one is in front of the separator is connected.

It is understood that the holding device can be implemented in different ways. For example, the holding device can comprise a latching unit, by means of which the separating disk can be temporarily held in the access position by a releasable form-fitting latching connection until this latching connection is released again with the aid of the timer or other measures after the intended holding time or with the aid of the presence sensor.

An embodiment variant in which the holding device comprises a magnet, preferably an electromagnet, and whose magnetic force can hold the separating disk that can be opened and closed against the opposing force has proven to be particularly advantageous in terms of construction.

This is due, on the one hand, to the fact that a magnet, in particular an electromagnet, can be actuated particularly easily in that this magnet only needs to be controlled electrically, for example by means of the timer or the presence sensor. This alone makes it very easy to configure and implement different temporary hold times.

On the other hand, incorrect operation of the separating device and thus any associated damage to the holding device can be largely avoided, since only one, preferably selected accordingly, can be avoided. Magnetic force has to be overcome, should a customer want to close the separating device manually, in particular with a little increased effort.

Furthermore, a magnet-based holding device can be easily cleaned with a suitable configuration, which can also reduce the risk of undesired nucleation on a merchandise presenter. In general, such a magnet-based holding device can be provided with relatively smooth surfaces on which dirt or the like can collect and stick with difficulty.

Specifically, a holding device comprising a magnet can in particular be designed in such a way that electrical energy is applied to it only in the holding state. This can be implemented, for example, in that a measuring device, such as an electrical contact, a contact switch or a reed switch or the like, is used to determine whether the separating disk has reached its access position in order to apply electrical energy to an electromagnet so that it then hold the cutting disc in this position until the electrical energy is switched off again.

Alternatively, a permanent magnet can be used, for example, to hold the cutting disk in its access position, while a repelling electromagnet, which can overcome the magnetic force of the permanent magnet, can apply a corresponding impulse to the cutting disk so that it moves away from the permanent magnets then solves.

In the latter case, energy is then only required during this pulse.

An advantageous embodiment variant provides for the holding device and / or the timing circuit to have a defined holding time of more than 3 s, preferably more than 5 s or more than 10 s, particularly in a customer operation, so that a customer suffices when the cutting disc is held in the access position Time remains. Goods can be removed from the room through the separating device without the separating disk performing a closing movement and possibly running against or striking against limbs of the customer located in the associated access opening.

It is not only expedient in this context if the holding device and / or the timer enable a defined holding time of less than 25 s, preferably of less than 20 s or less than 15 s. In this way, it can be ensured, especially in customer operation, that the separating device closes again automatically within a non-critical time window, although it is delayed so that the temperature set for the room cannot be measured or is only changed uncritically when the separating device is temporarily open.

The holding times suggested above can be selected flexibly in particular according to the type of goods located in the room or the type of goods presenter. However, they can also be freely selected completely independently of this, if this appears technically feasible and feasible.

The holding device can, however, also be implemented, for example, by a motor drive which is able to hold the cutting disc in its access position. If the separating disk is then to be brought back in the direction of the separating position, instead of releasing it, the separating disk can also be specifically moved in the corresponding direction by the motor drive, which can then also take over the functionality of the control means if necessary. If necessary, gravity can also be used to support this, whereby the motor drive may even only have a braking effect.

Any sensor can be used as a presence sensor, by means of which the presence of people or - of course - the absence of people can be determined in any way. For example, infrared sensors or heat detectors come into consideration here, which are already sufficiently known on the market for alarm systems, for example, in order to be able to measure the presence or absence of people. It is also conceivable that cameras are used as presence sensors, whereby it is advisable here to design the cameras from the outset in such a way that they can only detect the presence or absence of people in order to avoid any violations of data protection from the outset to be able to. It goes without saying that photocells, light barriers or acoustic sensors can also be used as presence sensors, as long as these, possibly also in combination with one another, deliver sufficiently reliably relevant measurement results.

It goes without saying that the timer and the presence sensor, depending on the specific requirements, can be used side by side, that is, together, or alternatively. For example, if an absence is detected, a certain holding time can still be waited until the holding device releases the separating disk.

Accordingly, it is also advantageous if the open and closable partition is held in its access position against the counterforce by a holding device and is released after a previously defined holding time and / or in the absence of people in front of the partition.

In particular, it goes without saying that the provision of a timer and / or a presence sensor or the release after a previously defined holding time and / or in the absence of people can also be advantageous regardless of the other features of the present invention.

Thus, cumulatively or as an alternative to the other features of the present invention, a goods presenter with a goods space that is separated from the separating device for separating a space from the surroundings to the surroundings, and with a frame carrying the separating device, the separating device being a includes openable and closable partition that is manually moved against a counterforce from a separation position in which it separates the room from the environment, into an access position in which the room is accessible from the environment, and by the counterforce from the access position can be brought into the separation position. characterized in that the separating device comprises a holding device which holds the separating disk in its access position against the opposing force and is connected to a line switch to release the separating disk again after a previously defined holding time or to spend it in the direction of the separating position in order to have access for a Customers on goods through a separating device to make it operationally reliable and yet easier and at the same time to improve the effectiveness of a temperature-controlled device for presenting goods, in particular a refrigerated shelf, with a goods room and with a separating device for separating the goods room from the environment.

Accordingly, a method for separating and making accessible a room, preferably a temperature-controlled room, which is particularly suitable and intended for the presentation and / or storage of goods, in which an openable and closable partition plate of a partition device counteracts a counterforce of a separating position, in which it separates the room from the surroundings, into an access position in which the room is accessible from the surroundings, manually brought and brought from the access position into the separating position by the counterforce, characterized in that the separating disk is in their access position is held against the counterforce by a hall facility and released after a previously defined holding time has elapsed in order to make access for a customer to goods through a separating device more reliable and yet simpler and at the same time the effectiveness of a temperature-controlled device for presenting v on goods, in particular a refrigerated shelf, with a goods space and with a separating device for separating the goods space from the environment.

By means of such a line-connected holding device, with a suitable configuration, a self-closing separating device can be implemented particularly inexpensively on a merchandise presenter or a merchandise counter, in particular on a refrigerated counter or the like.

In contrast to conventional separating devices of the generic type, which either remain in their manually moved position, or move independently from such a position into a closed position, the present separating device advantageously realizes a time-delayed closing.

In this way, on the one hand, a device for presenting and / or storing goods be operated more effectively in terms of energy, since in the present case it is prevented that the separating device inadvertently remains open for a long time. On the other hand, the operation for an operator of the separating device or a customer is more comfortable, since the separating device does not have to be actively closed manually after goods have been removed, nor does the separating device close immediately as soon as an active manual open action or the customer does not keep it open, so that the customer has enough time to remove goods through the separating device without the customer having to continuously hold up the separating device or repeatedly push it open.

Alternatively or cumulatively, a separating device can be used to separate a room, preferably a temperature-controlled room, which is particularly suitable and intended for the presentation and / or storage of goods, from the surroundings, the separating device comprising a separating disk mounted in a guide that can be moved manually against a counterforce from a separating position in which it separates the room from the environment into an access position in which the room is accessible from the environment and can be brought from the access position to the separating position by the counterforce characterized in that the separating device comprises a holding device which holds the separating disk in its access position against the counterforce and is connected to a presence sensor in order to release the separating disk again or to move it towards the separating position when there is no person in front of the separating device, to thereby To make access for a customer to goods through a separating device more reliable and yet simpler and at the same time to improve the effectiveness of a temperature-controlled device for presenting goods, in particular a refrigerated shelf, with a goods room and with a separating device for separating the goods room from the environment.

Likewise, cumulatively or as an alternative to the other features of the present invention, a method for separating and making accessible a room, preferably a temperature-controlled room, which is particularly suitable and intended for the presentation and / or storage of goods, with one open and one Closable partition of a partition device against a counterforce from a partition position, in which it separates the room from the environment, into an access position in which the room is accessible from the environment, manually brought and brought from the access position to the partition position by the counterforce , characterized in that the separating disc is held in its access position against the counterforce by a holding device and is released in front of the separating device in the absence of people in order to make access for a customer to goods through a separating device more reliable and yet simpler and at the same time to improve the effectiveness of a temperature-controlled device for presenting goods, in particular a refrigerated shelf, with a goods space and with a separating device for separating the goods space from the surroundings.

This also makes it possible. that the operation for an operator of the separating device or a customer can be more convenient, since the separating device does not have to be actively closed manually after goods have been removed, nor closes immediately as soon as an active manual opening or holding open by the customer fails, so that the customer has enough time to remove goods through the separating device without the customer having to continuously hold up the separating device or repeatedly push it open. The presence sensor preferably closes when the presence sensor just detects the absence of people.

For easier loading of the room or for cleaning purposes and the like, it can be advantageous if the holding device can hold the open and closable partition permanently in the access position in a maintenance state. For this purpose, the function of the holding device can be activated, for example, permanently, for example by bridging the timer or bypassing it or not activating it at all, or for example by bridging or deactivating the absence sensor that determines the absence. In this way, the holding device can maintain its holding function for the cutting disk at least until the idle device is deactivated again or the cutting disk is manually moved out of its access position. It is also conceivable to actively deactivate the validation status by turning off a switch and the like. Alternatively, for example, a comfortable long time interval can be set with regard to the holding time, which is for example 5 m, 10 m or 20 m or even longer, so that loading and / or cleaning processes can be safely completed.

Such a maintenance state can in particular ensure that the openable and closable partition does not close independently during maintenance work, such as in particular during any loading or cleaning activities, which on the one hand can be a nuisance for the correspondingly active staff and on the other hand can even involve a risk of injury.

The openable and closable separating door is preferably a flap, which means that it essentially rotates about an essentially horizontally aligned axis of rotation, a rotating-sliding movement also being conceivable here if necessary. A flap enables the same to be guided in a stable manner in a structurally simple manner, particularly in the case of heavier cutting disks. By suitably designing the control pin and / or the hall device, such as a magnet or some other razor device, greater forces can also be taken into account here.

In addition, it has been found that flaps, in particular even if the associated separating disks are relatively heavy, can be stored or guided in a relatively simple structural manner in an operationally reliable manner.

As already explained above, the control means for controlling the counterforce and therefore also the correspondingly controlled counterforce can move the open and closable partition pane from its access position to its partition position within a time window of at least 3 s or 12 s and a maximum of 40 s, which enables customers to access goods through the separating device in an operationally reliable and yet simple manner. The latter applies in particular when the time window is between at least 4 s or 5 s and a maximum of 35 s.

The lower limit of 3 s, 4 s, 5 s, 12 s or 13 s, regardless of the above-mentioned upper limit, enables the open and closable partition not to close too quickly, so that the impulse of the partition is not too high if the open and closable partition does come into contact with people, for example with a customer or staff.

On the other hand, the upper limit of 40 s or 35 s allows, regardless of the lower limit, that a closing movement is still sufficiently recognized by people so that they can avoid any movement of the open and closable separating row when it closes: or else be able to stop the movement sequence in a targeted manner in order to bring the open and closable partition back into its access position.

The open and close separating disk can be controlled by the control means or the counterforce, preferably at an angular velocity greater than 0.039 rad / s and / or less than 1.047 rad / s, in particular less than 0.785 rad / s, preferably 0.262 rad / s, from its access position to its Separated position are spent, as has already been explained above.

Here, the angular velocity (ω) is the quotient of the angle covered by the openable and closable separating window in a time interval and the corresponding time interval. In the present case, the angular speed is defined in rad / s, whereby the angular speed can optionally also be specified in ° / s. Here, 0.039 rad / s corresponds to approximately 2.25 ^c / s, 1.047 rad / s corresponds to approximately 60 ° / s. 0.785 rad / s and about 45 ° / s, preferably and 0.0262 rad / s about 15 ° / s, respectively.

Depending on the specific sequence of movements, the actual body speed in the open and closable partition pane can deviate from these limit values if a translational movement is also carried out by the open and closable partition pane.

The angular velocity is particularly preferably greater than 0.045 rad / s, which corresponds to approximately 2.57 ° / s, which ensures that the separating disk that can be opened and closed moves or closes at sufficient speed.

In particular, the angular velocity can be less than 0.785 rad / s. which corresponds to 45 ° / s, so that the openable and closable separating disk does not turn too quickly when it closes due to the counterforce. Depending on the specific implementation, the angular velocity can also be less than 0.262 rad / s, which corresponds to 13.85 ° / s.

In particular, it is conceivable that the separating disk closes within 4.5 s or 5 s, which is evidently perceived as pleasant by consumers. This corresponds to angular velocities of approximately 0.638 rad / s, which corresponds to approximately 36 ° / s.

It goes without saying that the features of the solutions described above or in the claims can optionally also be combined in order to be able to implement the advantages cumulatively.

The in 1 until 3 presented goods presenter 20th has a goods room 27 on in which goods can be presented. The goods presenter indicates this 20th the 1 until 3 on the one hand, goods shelf 25th on, being in the goods room 27 on the other hand, a shelf (not numbered) is available.

The goods presenter 20th the 1 until 3 points both to a customer side 38 as well as on an operator side 39 a warehouse access 28 on, being the goods room 27 this goods presenter 20th remains open on the operator side and on the operator side for operating personnel 39 a cutting board 80 is provided, which can serve as a shelf and is also available to the staff for activities. If necessary, however, a separation of the goods space 29 can also be provided here. In alternative embodiments, however, it is also conceivable that the goods presenter can only be accessed from one side.

The product presenter is effective on the customer side as well as on the top and sides 20th to 1 until 3 a separator 10 by means of which the goods room 27 from the surroundings 31 is separated, in this embodiment the goods space 27 the one from the separator 10 separated room 30th is equivalent to. If necessary, the can by the separating device 10 separated room 30th also smaller than the goods room 27 be trained.

The cutting device essentially comprises three stationary cutting disks 11 that act as side panels 64 or are designed as an upper wall.

As already stated above, the separating device is 10 to the operator side 39 open, which however does not necessarily have to be the case in alternative embodiments. For example, walls or stationary separating disks or openable and closable separating disks can also be provided there. It goes without saying that the separating device 10 in different embodiments, it can optionally also be accessible only from one side, so that it does not have a customer side or the customer side 38 and the operator side 39 on the same side of the goods presenter 20th can be found.

It also includes the separator 10 a cutting disc 12th , which in a guide designed as a rotary guide 13th is stored.

The leadership 13th is here on a separator carrier 61 arranged, which in turn of a Gestel l 63 of the goods presenter 20th will be carried.

The separating device carrier 61 also carries the stationary cutting disks 11 .

The ones in the lead 13th bearing cut-off wheel 12th can between a separation position 32 . in which it is closed and an access position 33 in which the room 30th or the whale room 27 is accessible, be moved manually, including a handle in this embodiment 16 in the open and closed, in the leadership 13th bearing cut-off wheel 12th is provided. It goes without saying that instead of the handle 16 other measures can also be provided to open and close the partition 12th to be able to operate manually.

The one that can be opened and closed or in the guide 13th bearing cut-off wheel 12th is via its guide, which is designed as a rotary guide 13th with a pivot axis parallel to the ground 34 or parallel to the horizontal 35 pivotally mounted so that it is designed as a flap itself.

A guideway then follows from this 37 for the openable and closable cutting disc 12th , which is substantially circular.

Thanks to the open and closable partition 12th can be an access opening 18th , which in this embodiment, the warehouse access 28 corresponds to their separation position 32 closed and in their access position 33 be opened.

As already explained above, the opening can be done manually against a counterforce 40 take place, with this counterforce 40 is provided proportionally by gravity.

In addition, the in 1 until 3 illustrated embodiment control means 41 to control the counterforce 40 , which in this embodiment is a spring element 42 and a damper element 43 have, with - depending on the specific requirements - in different Ausführungsbeispiclcn on the spring element 42 and / or the damper element 43 can possibly be dispensed with.

In the present exemplary embodiment, the spring element is 42 designed as a gas pressure spring, which is aligned such that by the spring element 42 or the corresponding gas pressure spring counteracts the force of gravity, so that the force required for manual actuation is correspondingly reduced. This then also requires a correspondingly lower counterforce 40 as if the one in the lead 13th mounted or open and closable cutting disc 12th contrary to the force of gravity actually acting on it had to be lifted. The reduced drag 40 then also causes a correspondingly lower lowering speed of the open and closable cutting disc 12th . It goes without saying that other spring elements 42 , for example disc spring assemblies and the like. can be used cumulatively or alternatively.

The damper element 43 is designed as an oil damper in this exemplary embodiment, and a gas pressure damper can also be used if necessary.

Through a suitable design of the damper element 43 it can be guaranteed that this occurs when opening the open and closable partition 12th does not have a dampening effect or has only a very little damping effect, while it does so when the open and closable partition window is closed 12th more attenuates to the lowering speed in this cutting disc 12th to reduce.

So that the means of control 41 to control the counterforce 40 can work as reliably as possible, these are via a linkage 90 and a lever assembly 91 with the openable and closable partition 12th effectively connected.

In this way, any thermal loads can be kept away from such sensitive assemblies.

In addition, it is ensured that the control means 41 more than 4 cm from the goods space 27 and any thermal load emanating from it are removed.

As a wall 83 of the goods presenter 20th over which the control means 41 from the goods room 27 of the goods presenter 20th are separated, a table is used in this embodiment 81 on which on the one hand the goods floor 25th is realized and in which, on the other hand, a goods tub 82 . from which the customer can take suitable goods such as cutlery or sauces or the like.

Also the side wall 64 can each be used as walls 83 which are to be used for such a separation process.

Around the openable and closable partition 12th in their access position 33 to hold is a holding device 50 provided, which in this embodiment is an electromagnet 51 and a counter plate 52 for the electromagnet 51 includes.

In this embodiment, the counter-plate is here 52 on the linkage 90 on the lever assembly 91 remote side of the linkage 90 on which the spring element 42 or the damper element 43 attack, arranged.

At the electromagnet 51 is also a contact switch 59 provided, which by the counter plate 52 can be closed. In this way the electromagnet can 51 operated when the contact switch 51 closed and therefore the openable and closable partition 12th in their access position 33 is located.

This in 1 until 3 The illustrated embodiment also includes a presence sensor 70 , which on the customer side below the table 81 is arranged. It goes without saying that there is also a different arrangement of the presence sensor in different exemplary embodiments 70 can be provided. As a presence sensor 70 a motion detector is used in this exemplary embodiment. In alternative embodiments, a camera or an infrared sensor or the like can be used here.

Is the contact switch 59 closed and therefore the electromagnet 51 switched on and the openable and closable partition window 12th in their access position 33 is located, so is the open and closable partition 12th kept open until the presence sensor 70 no persons present were determined. Then the electromagnet 51 released and the openable and closable partition 12th can be due to the opposing force 40 which by the control means 41 is controlled, close independently.

It goes without saying that activation via reed switches and a timer can also be used cumulatively or alternatively.

With these arrangements it is easily possible to use the electromagnet 51 to be de-energized when using the proximity sensor 70 the absence of persons or the absence of persons is detected. This then leads to a release of the electromagnet 51 , so that the openable and closable partition 12th can lower.

Regarding the means of control 41 as well as the linkage 90 and the lever assembly 91 it is conceivable that this is only on one side of the goods presenter 20th or on two sides of the goods presenter 20th are provided.

The means of control 41 are here with the linkage 90 , the lever assembly 91 and the openable and closable partition 12th matched that the latter in about 15 to 30 s from their access position 33 to their separation position 32 sinks. If necessary, a time span of up to 40 s and / or longer than 3 s can also be selected here, if this appears advantageous.

The forces to be applied, in particular by the damper element 42 or the spring element, can also be determined from these time specifications 43 , taking into account the dimensions of the openable and closable partition 12th and their leadership 13th calculate.

The electrical connection of the contact switch 59 with a timer 55 and a maintenance switch 56 and the electromagnet 51 is exemplary in 4th shown. Becomes the contact switch 59 closed when the counter plate 52 the electromagnet 51 is reached, the timer is activated 55 activated and the electromagnet 51 performs its holding function. After the previously selected time for the timer has elapsed 55 the contact is opened so that the electromagnet 51 becomes de-energized. This gives the counter plate 52 free again, so that in the lead 13th mounted or open and closable cutting disc 12th due to the opposing force 40 towards their separation position 32 emotional.

It goes without saying that, in a different embodiment, the magnet can also be designed in such a way that it forms the counterplate in the de-energized state 52 attracts, which can be implemented, for example, by a permanent magnet, and when energized, the counter-plate 52 by a field directed opposite to the permanent magnet, so that it is released accordingly. The current can then be supplied accordingly via the timer 55 which should then be modified in a suitable manner.

Through a maintenance switch 56 can the electromagnet 51 of the in 1 until 4th illustrated embodiment are supplied with current over a longer period of time, so that maintenance work is carried out by the maintenance switch 56 conditional state can be done in peace.

In the present embodiment, the contact switch 59 than through the counter plate 52 operated switch formed, which is closed when the counter plate 52 the electromagnet 51 achieved.

In an alternative embodiment, two electrical contacts can also be made through the counterplate 52 be bridged if this is the magnet 51 reached in order to complete an associated circuit in this way.

In an alternative embodiment, a corresponding contact switch 59 possibly also on the counter plate 52 be provided, in which case an electrical line may then have to be routed to a moving assembly, which is usually associated with increased effort.

In addition, on the counter plate 52 a small permanent magnet can be provided as a control magnet, which is a reed sounder 54 closes the one near the electromagnet 51 is arranged as this is exemplified in 5 is shown. Here are the reed switches 54 and the aforementioned small permanent magnet aligned with one another in such a way that the reed sounder 54 by the permanent magnet can be just before the counter plate 52 in contact with the electromagnet 51 got. Otherwise, the behavior then corresponds to the behavior as it is based on the exemplary embodiment 1 until 4th has been explained and can also include an interconnection by means of which the electromagnet 51 is de-energized when the absence of people by the presence sensor 70 or the lack of presence of people is detected, then the openable and closable or in the leadership 13th bearing cut-off wheel 12th to release and to enable their lowering.

A concrete implementation of such an interconnection is shown, for example 6th , in which a switching relay 71 with the presence sensor 70 and the reed switch 54 is connected in series, with instead of the reed switch 54 here, for example, the contact switch 59 the end 4th can be used as an example. By closing the presence sensor 70 and an opening of the openable and closable separating disk or that is mounted in the guide 13 12th until the reed switch closes 54 or the contact switch 59 then becomes the switching relay 71 closed, which also causes the electromagnet 51 is energized. As a result, the separating disk that can be opened and closed or is mounted in the guide 13 becomes 12th then held open until the presence sensor 70 the absence of people or their lack of presence is detected, so that the circuit for the switching relay 71 is opened so that the electromagnet 51 is switched off. The means of control 41 then ensure a correspondingly controlled lowering of the openable and closable or in the guide 13th bearing cut-off wheel 12th In a different embodiment, a time delay, for example via a capacitor or a timer or the like, can also be provided here as a supplement.
