Abstract

The container has a housing (1) formed from two closed housing side walls, a housing cover (1b), a housing base (1c), and a housing rear wall (1d), and two-part roller blinds e.g. head roller blind (6a) and front roller blind (6b), for closing an access opening (3) in the housing. The roller blinds are designed independent of the housing, received in a roller blind housing (7), and arranged on the housing cover. Guide rail devices (10-12) extend from an outlet slot (13) in the roller blind housing to a lower edge (5) of the access opening.

Description

The invention relates to a goods presentation container, in particular a cooling rack, with a housing, and with an optionally split-two shade with Frontrollo and Kopfrollo for closing an access opening in the housing.

Goods presentation containers are used for storing and also advertising of goods, especially food in shops. In the present case, it is primarily a matter of a refrigerated goods presentation container, ie such a container, which regularly stores refrigerated food for immediate customer withdrawal. Such goods presentation containers are generally refrigerated shelves, that is, open refrigerators with one or more shelves in order to keep foods that are in constant need of refrigeration readily accessible to customers. Access to such refrigerated shelves is made possible via the at least one access opening.

In contrast to, for example, closed refrigerators, there is a constant exchange with the warmer ambient air inside the shop with open refrigerators or refrigerated shelves. For this reason, the energy consumption in such open refrigerators or shelves is significantly higher than that of closed refrigerators. For this purpose, one increasingly uses in practice refrigerated shelves, in which the access opening can be closed, for example, by glass revolving doors or so-called night blinds. The night blinds are used in particular outside shop opening hours. In contrast, the glass hinged doors ensure a relatively low energy loss during the entire operation.

However, this only applies in the event that a relatively low customer frequency is observed. Because at high customer frequency, the glass doors or Glass revolving doors are often opened so that energy efficiency is significantly worsened. In addition, such glass doors are associated with the disadvantage that in the area of the customer a suction effect is observed by the outside penetrating warm air. Quite apart from that, glass doors or glass turntables during customer use are a barrier for the respective customer and disrupt the sale.

In the generic state of the art according to the DE 102 36 212 A1 a refrigerator is described, which is equipped with a thermally insulated housing. In addition, the known refrigeration device has a heat-insulating cover formed by longitudinally displaceable rolloartig contiguous contiguous also heat-insulating elements is formed. As a result, the access opening has a total thermally insulating trained cover and can be closed with the help of this cover.

The two realized at this point hollow chamber roller blinds are guided in grooves longitudinally displaceable. The grooves are located within the mutually facing sides of the side walls and are preferably formed circumferentially along the peripheral edge of the side walls. As a result, a perfect guidance of the roller blinds may be achieved, but such a solution can not be retrofitted, for example. In addition, the known teaching pursues the DE 102 36 212 A1 ultimately the goal to replace previously used flaps or doors through the roller blind, which is logically closed again after removal of the desired food or must be closed. This is where the invention starts.

The invention is based on the technical problem of developing such a goods presentation container so that the customer use at simultaneously reduced compared to the prior art energy consumption is not affected.

To solve this technical problem, a generic goods presentation container in the invention is characterized in that the composite of headrest and Frontrollo roller blind total or at least the headrest is designed independently of the housing. This is understood according to the invention that the roller does not rely on the housing or parts thereof for its storage and guidance. That is, the roller blind according to the invention generally has its own roller blind housing and / or a housing-independent guide rail device. As a rule, at least the housing-independent guide rail device is realized in order to realize the independent design of the roller blind from the housing. As a result, the relevant roller blind can easily be retrofitted to an existing housing. For this purpose, it is only necessary to mount the housing-independent guide rail device to the housing and set the blind - with or without roller blind - also on the housing or in the housing. In any case, the independent design of the roller blind from the housing usually implies that the roller blind is not guided in housing-side guide grooves, but insofar relies on a housing-independent guide rail device, which can be easily retrofitted. In this case, the roller blind can be arranged in the own roller blind housing outside of the housing. But it is also an arrangement of the blinds without blind housing on the housing conceivable.

In the former case, it is recommended that the roller blind is placed together with the roller blind housing outside the relevant housing, for example on a housing cover. In this case, the blind is usually taken up wound up in the blind housing. Also a folding arrangement of the Roller blinds in the roller blind housing is possible and is covered according to the invention. The second alternative corresponds, for example, to the fact that the roller blind is placed on a rear wall of the housing or in the region of this rear wall of the housing without its own roller blind housing. Of course, a stocking of the blinds in a separate roller blind housing is also conceivable in this case and is covered with.

In any case, the roller blind ensures that the access opening in the housing is completely or partially closed. In this case, a partial closure of the access opening already during operation, that is, during store opening times, depending on the customer frequency, the air temperature and / or humidity in the shop or the degree of filling of the goods presentation container as a whole. Complete closure of the access opening by means of the blinds takes place regularly outside shop opening hours, during shop closing hours. The roller blind is usually operated electrically, so has an electric drive. This electric drive is regularly - like the roller blind - designed independently of the housing. That means he may have his own energy supply, which is not mandatory.

As already described, it is possible within the scope of the invention for the roller blind housing to include the outstretched - and thus not wound up and also not folded - roller blind in its entirety. In this case, the roller blind and with it the roller shutter housing is regularly in a parking position. In most cases, the parking position of the outstretched roller blind and consequently also of the associated roller shutter housing corresponds to its arrangement on a housing rear wall. That is, the housing rear wall is used as a kind of parking device for the extended roller blind and the extended roller blind receiving roller blind housing. In principle, the two measures can also be combined. Then takes the blind housing, for example, only to Part wound roller blind and in addition the rest of the outstretched roller blind in its interior. Also in this case, the roller blind housing with the roller located therein can be arranged for example on the housing cover or even on or even in the rear wall of the housing.

In any case, the invention prefers an attachment of the roller blind housing outside the actual housing for the cooling rack, so that the attachment of the roller blind housing with the roller located therein succeeds easily. In principle, the roller blind housing with the roller blind but also in the housing for the cooling rack can find space, but usually not succeed for reasons of lack of installation space.

Because the housing for the cooling rack is usually equipped with closed housing side walls or side walls, a closed rear wall or housing rear wall, a closed housing cover or ceiling and finally a closed housing foot or foot and a contrast open front or front panel. In this case, the front or housing front defines the access opening in the otherwise closed housing, through which a user or customer can easily grasp the food located and cooled on one or more shelves.

Of particular importance in the context of the invention is that the goods presentation container or the cooling rack has a dynamic air flow or cooling air flow. For this purpose, at least one cooling unit, in particular cooling air unit, is provided, which generates one or more cooling air veils in the region of the access opening. By this one or more cooling air curtain in the access opening the energy consumption is already significantly reduced, because the veil or cooling air curtain intensive exchange between the warmer ambient air and the inside the goods presentation container or cooling rack regularly circulating guided cooling air prevented. In this case, the cooling air curtain may consist of two individual cooling air curtains guided parallel to one another, which have a different speed.

It may be similar in the realization of the cooling air curtain, as the US 4,977,754 for example, in the local FIG. 2 shows. Of course, this is not meant to be limiting. Either way, the cooling air unit producing the one or more cooling air curtains still provides the opportunity to allow unhindered access to refrigerated foodstuffs located in the merchandise presentation container or in the refrigerated display shelf when the roller blind is opened. Outside the shop opening hours, however, the blind and thus the access opening in the housing is regularly closed.

As a result, the energy consumption can be significantly reduced compared to previous solutions and is expected at the same time with increased customer acceptance compared to solutions with, for example, glass revolving doors. In order to improve the energy balance even further at this point, the housing for the goods presentation container is designed to be heat-insulating overall. The same applies to the roller blind, which is generally designed as a roller shutter or roller shutter. This roller shutter armor or the roller blind has individual pivotally interconnected and thermally insulated roller shutter rods. The roller shutter bars are advantageously made of plastic and may, if necessary, be transparent.

It has proven useful if the individual roller shutter or roller poles are designed as hollow chamber profiles. The hollow chambers of these hollow chamber profiles like with a heat-insulating material such as be filled with foamed plastic in order to increase their thermal insulation value compared to an otherwise realized air duct yet.

Of particular importance for the invention is further that the already mentioned housing-independent guide rail device for the roller blind or the overall formed roller shutter is realized. Due to the housing-independent design of the guide rail device, the retrofitting of an existing goods presentation container especially refrigerated shelves is particularly facilitated. For the retrofitting, it is only necessary to equip the existing cooling rack with the roller blind housing including roller blind located therein and finally the housing-independent guide rail device, which is usually mounted outside the housing. As a result, it is not necessary, for example, to resort to guide grooves introduced or to be introduced into housing side walls for the roller blind. Rather, these guide grooves are usually provided by two or more side rails, which are components of the guide rail device.

As a result, there is the additional possibility of using the guide rail device as a whole or the individual side rails for guiding, for example, two adjacent roller blinds. In addition, this makes it particularly elegant, interpret the axial length of the blinds ultimately independent of the axial length of the housing. In fact, the length of a single roller blind or the roller length may correspond to one or more times the housing length. As a result, for example, a plurality of housings can be equipped or retrofitted with a single roller blind according to the invention or a correspondingly designed roller blind unit. It is equally possible to dimension the roller length less than the housing length.

In addition, the guide rail device still has at least one end rail, which regularly record in the closing direction of the blinds last roller blind rod or at this point last roller blind. This usually goes for both the headrest and the Frontrollo. This cover rail can now also take on additional functions (in addition to their actual closing function). Thus, it is conceivable to integrate a crush protection in this end rail, which prevents, for example, injury when closing the blinds. In addition, this anti-crushing can correspond during its activation, that the blind is opened again.

In addition, the end rail can be equipped with additional functions. For example, it is conceivable to integrate a lighting. This can be used particularly advantageously with a partially closed access opening in order to illuminate the goods still in the cooling rack.

The design is generally such that the guide rail device extends from an exit slot in the roller blind housing to a lower edge of the access opening. That is, the guide rail means bridges the entire path of the blind housed in the blind housing from its outlet slot to the lower edge of the access opening.

In this context, it has further proven to be advantageous if the guide rail device additionally has one or more deflection elements in addition to the at least two side rails and the at least one end rail. With the help of this one or more deflection elements, the roller blind accommodated in the roller shutter housing, for example, in a vertical arrangement in the region of the access opening to be closed transferred. This is necessary, inter alia, when the roller blind housing with the roller blind located therein is arranged on the housing cover. Since the housing cover is generally oriented horizontally, the roller blind guided over the outlet slot of the roller housing must be deflected from a horizontal or almost horizontal orientation into a vertical orientation when it is transferred to the closure of the access opening. This is ensured by one or the several deflection elements. These may be arranged in the region of an upper edge of the access opening. The upper edge is found regularly in the area of a top panel of the housing.

The guide rail device described can be equipped with at least one additional element to represent other functions. This additional element may be a lighting unit, a display unit, a fuse unit or the like. This one or more additional elements can be realized individually or in any combination on or in the guide rail device. Thus, it is conceivable, for example, for the illumination unit to be one or more light sources, for example LEDs, which illuminate the access opening or the shelves and / or front edges of the shelves on which price tags or other product identifications are located. The additional element may be arranged on or in the side rails of the guide rail device. In addition, it is as described but also possible to provide the additional element on or in the end rail.

Furthermore, the additional element can alternatively or additionally be designed as a display unit. In this case, the guide rail device itself may serve as a marking surface for the goods stored in the refrigerated shelf. Even the roller blind itself may act as a marking surface. Finally, the guide rail device may also have a securing unit as an additional element. Such a security unit is conceivable, for example, to lock the lowered and the access opening closing blind relative to the housing. As a result, access to refrigerated shelves food is prevented when the access opening is closed.

The roller shutter housing may have an integrated drive to assist the retrofitting advantageous. In this case, the drive generally ensures that the roller blind can be acted upon selectively or can be acted upon to realize certain opening degrees of the access opening. Thus, it is conceivable to change the opening degree of the access opening depending on the inventory. If, for example, only individual shelves of the refrigerated shelf are filled, the roller blind can be moved with the aid of the drive so far that the access opening only allows access to the filled shelves. In addition, it is conceivable to control the drive daytime and / or weekday and / or temperature and / or season and / or room climate dependent. For this purpose, the drive is advantageously associated with a controller which, depending on the aforementioned parameters and exemplifies the degree of opening of the access opening by an appropriate loading of the blinds.

Of course, this roller blind control can be set differently from goods presentation container to goods presentation container. However, it is also possible for the individual drives to be acted upon by a plurality of goods presentation containers or refrigerated shelves with a common control, so that via said control the opening degree of all access openings of the goods presentation containers respectively refrigerated shelves located in the shop are specified. The individual goods presentation containers or refrigerated shelves can be modularly attached to each other, so that different lengths of cooling sections can be realized in the axial direction.

A further standardization in this context proposes the invention in that the roller blind and the roller blind housing (and of course also the guide rail device) are adapted to the length of the housing. However, it is also conceivable to adapt the roller blind, the roller shutter housing and optionally the guide rail device to the length of a plurality of juxtaposed housing. In this case, the roller blind including blind housing thus spans two, three or even more housings in one go. This ensures a particularly cost-effective production and assembly and, moreover, ensures that the access openings of the housing of the individual goods presentation containers combined in this way are opened or closed in phase or have the desired degree of opening.

As a result, a goods presentation container, in particular a cooling rack, is made available, which has a predominantly uniform temperature distribution in its interior, which is essentially explained by the cooling air unit and the cooling air curtain produced thereby. In this way, the heat exchange between the warmer ambient air and the open access opening of the refrigerated shelf can already be reduced to a minimum while at the same time unhindered accessibility of the refrigerated goods. Of particular importance now is that during shop closing times and / or when not in use, the housing of the goods presentation container according to the invention undergoes a hermetic as it completes.

This is ensured by the roller blind with the separate roller blind housing, which experiences a perfect guidance through the housing-independent guide rail device. The guide rail device ensures that column be avoided between the individual blinds or to the side walls or at the front of the refrigerator. Rather, the design is usually made such that the individual side rails of the guide rail device directly adjoin one another and, in conjunction with the roller shutter rods guided in the two or more side rails, provide a hermetic closure of the access opening.

Due to the heat-insulating design of the individual roller blinds or the roller shutter (panzer) rods, the heat conduction and convection is effectively reduced. A dew point can be avoided on the outer surface of the individual Rollolamellen or shutter bars. If appropriate, the design can also be such that the outer surface of the closed roller blind is acted upon by, for example, a (waste heat) flow of the cooling air unit in order to prevent condensation at this point.

All of this succeeds as part of a solution that can be implemented even with existing heat presentation containers. This is ensured by the separate roller blind housing for receiving the roller blind as well as the housing-independent guide rail device. Both elements can be easily attached to an existing refrigerator shelf and use for the described operation. This is supplemented by the fact that in the blind housing of the drive for the individual roller blinds is integrated, which can be easily addressed by a control system (for example, wireless) and operated.

Overall, the invention speaks of a roller blind in the sense of a protective curtain for closing and opening the access opening. In this case, this protective curtain does not necessarily have to be wound onto a shaft, because even a stretched arrangement of the roller blind in the described parking position is included on the rear wall of the invention. Likewise, Rollo means not only a Schutzbehang of, for example, a substance, but this fall according to the invention especially Rollolamellen plastic, which are hinged together to form a mat or Schutzbehang. In this respect, the roller blind according to the invention is synonymous with a roller shutter or generally a roller shutter, so a roll closure of individual hingedly interconnected roller shutter bars as a closure of the access opening.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:

Fig. 2

the goods presentation container in a schematic cross section.

In the figures, a goods presentation container is shown, which has in its basic structure on a housing 1 and provided in the housing 1 a plurality of shelves 2, which are adapted to hold refrigerated food. It can be seen that the housing 1 consists of two housing side walls 1a, a housing cover 1b, a housing foot 1c and finally a housing rear wall 1d. As a result, the housing 1 has a quasi-shell-like character, which leaves an access opening 3 open on its front side in order to allow customers unimpeded access to foods that are arranged on the respective shelf 2. Evidently the FIG. 1 a plurality of housing 1 can be summarized in longitudinal extension modular to a cooling section.

A cooling unit or cooling air unit 4 in the housing foot 1c ensures that cooled air is circulated inside the housing 1, as in FIG FIG. 2 is shown. As a result, a cooling air curtain is generated in the region of the access opening 3, which largely prevents the exchange of warm ambient air with the cooling air in the interior of the housing 1. For this purpose, the housing foot 1c is designed as a cooling trough. On the front side of this cooling trough or of the housing foot 1 at a lower edge 5 of the access opening 3, a warm air curtain may flow upward when the access opening 3 is completely or partially closed with the aid of a roller blind 6a, 6b. This may apply during shop closing hours, but is usually superfluous because the blinds 6a, 6b are designed to be heat-insulating, as will be explained in more detail below.

In normal operation, that is usually during the shop opening times and with the access opening 3 open, however, the described hot air flow is switched off. This hot air flow may be due to the warm exhaust air of the cooling unit or cooling air unit 4. In this case, the cooling unit or cooling air unit 4 may not be arranged in total in the housing 1, but it is alternatively also conceivable to work with a central cooling air unit 4 outside the housing 1, which supplies, for example, one or more housing 1 with cooling air. In this case, the cooling unit or cooling air unit 4 may even be arranged outside the shop, for example in a warehouse.

As already indicated, the two-part roller blind 6a, 6b used in the exemplary embodiment serves to close the access opening 3 in the housing 1. The roller blind 6a, 6b is configured in two parts with head shade 6a and front shade 6b in the example. In a comparative analysis of the individual functional positions FIG. 1 It is clear that the fully opened access opening 3 according to the left illustration in FIG. 1 this corresponds to the fact that both the headrest 6a and frontdoor 6b are completely retracted. In the middle Representation after FIG. 1 the access opening 3 is partially closed by the front door 6b is raised up almost to the first shelf 2 on the housing foot 1c. The very right representation in FIG. 1 Finally, shows a goods display container according to the invention in the embodiment as a cooling rack, in which both the Kopfrollo 6a and the Frontrollo 6b are closed, so that the access opening 3 undergoes a hermetic seal. The same then applies to the housing 1 as a whole. This condition is regularly taken during store closure hours or even when there are no products to be cooled and intended for the customers inside the refrigerated shelves, ie when not in use.

According to the present invention, the roller blind 6a, 6b is designed to be completely independent of the housing 1. In addition, at least the headrest 6a in the example case has its own roller blind housing 7, in which the headrest 6a is received, in particular the FIG. 2 shows. Of course, the headrest 6a and the front control 6b can be placed together in the blind housing 7. Likewise, a one-piece roller blind 6a, 6b can be accommodated in the roller blind housing 7. In addition, a separate blind housing 7 for the front wheel 6b can be realized.

In the exemplary embodiment, the roller blind 6a, 6b or the headrest 6a and also the front blind 6b are wound on a respective shaft 8. The shaft 8 has a drive 9. The drive 9 is integrated in the context of the embodiment in the blind housing 7. This applies in any case for the headrest 6a. In contrast, the Frontrollo 6b is taken together with its own and associated drive 9 in the housing foot 1c, and also advantageously wound up.

It can be seen that the roller shutter housing 7 is arranged outside the housing 1, thus being particularly suitable for a retrofit solution. As part of the presentation after FIG. 2 there is the blind housing 7 on the housing cover 1b, in the region of a rear edge of the housing cover 1b in extension of the rear wall of the housing 1 d.

According to the embodiment, the length of the blinds 6a, 6b and also that of the roller blind housing 7 is adapted to the length of the respective housing 1. But it is also possible that the blind 6a, 6b in conjunction with the blind housing 7 two or more housing 1 spans together and provides a common closure of the associated access openings 3 of the respective housing 1. This is not shown.

In order to guide the roller blind or headrest 6a received in the roller housing 7 and also the front wheel 6b accommodated in the housing foot 1c and to provide the desired hermetic closure of the access opening 3 or a desired opening degree of the access opening 3, a guide rail device 10, 11, 12 for the roller blind 6a, 6b provided. The guide rail device 10, 11, 12 is connected to an outlet slot 13 in the blind housing 7 on the one hand and extends the other hand to the lower edge 5 of the access opening 3. For this purpose, the guide rail device 10, 11, 12 consists of at least two side rails 10, a closing rail 11 and finally at least one deflecting element 12 together.

With the aid of the deflecting element 12, the head shade 13a entering from the outlet slot 13 or from it into a vertical or nearly vertical course in the region of the access opening 3 is transferred from a horizontal or nearly horizontal course parallel to the housing cover 1b. In this case, the access opening 3 of the at least two side rails 10 side limited. Finally, the end rail 11 is found on the foot, into which the roller blind 6a engages in the fully closed state. The closing rail 11 can be provided in the region of the lower edge 5 fixed to the housing foot 1c. But it is also possible to realize the end rail 11 - as in the embodiment - the head side of the front blind 6b. In this way, the headrest 6a engages in its closed state in the head-side end rail 11 of the also located in the closed state Frontrollos 6b. This becomes clear in a comparative analysis of the middle and right representation of the functional positions FIG. 1 ,

Due to the housing-independent design of the guide rail device 10, 11, 12 can be the guide rail device 10, 11, 12 as well as the roller blind 6a, 6b in conjunction with the roller housing 7 easily retrofit to an existing cooling rack. For this purpose, it is only necessary to attach the roller blind 6a, 6b including roller blind housing 7 in the exemplary embodiment on the housing cover 1 b and, moreover, to mount the guide rail device 10, 11, 12. As a result, the roller blind 6a, 6b in connection with the guide rail means 10, 11, 12 and in particular due to the side rails 10 in conjunction with the end strip 11 for a hermetic completion of the access opening 3 in the closed state. In addition, covers A can be provided, which protects the respective headrest 6a from dirt or other environmental influences in the embodiment.

The FIG. 1 shows that the guide rail device 10, 11, 12 can be equipped with additional elements 14. In the example case, these additional elements 14 are a lighting unit 14 composed of a plurality of LEDs or general light sources 14. The lighting unit 14 or the individual LEDs ensure that the access opening 3 and the interior of the housing 1 is illuminated. The same applies to a front edge of the shelves 2. In addition, other, but not shown, additional elements may be realized, for example, a (LCD) display unit on the two side rails 10, a fuse unit for locking the blinds 6a, 6b, etc ..

In the exemplary embodiment, the roller blind housing 7 accommodates the roller blind 6a or headrest wound up on the shaft 8. But it is also possible that the roller shutter 6a remains in its extended functional position and in a parking position an arrangement on the rear wall of the housing 1 d learns. In this case, the blind housing 7 is designed accordingly and takes the extended blind 6a on the rear wall of the housing 1 d.

To control the blinds 6a, 6b and the head shell 6a and the front blind 6b one or more drives 9 are realized. In the example shown, the headrest 6a and the front control 6b may each have their own drive 9. This drive 9 is on the one hand integrated into the blind housing 7 and found on the other hand in the housing foot 1 c, the former drive 9 unwinds the headframe of the shaft 8 and then wound up again, while the latter drive 9 for corresponding closing and opening movement of the Headrest 6a independent Frontrollos 6b ensures. This makes it possible to move the headrest 6a and the front door 6b independently of each other, so that virtually any opening degrees of the access opening 3 can be adjusted, as the FIG. 1 makes it clear.

In this way, the access opening 3 can be specified in terms of their degree of opening in dependence on various parameters. It is conceivable, for example, to open the access opening 3 more or less depending on the occupancy of the cooling shelf to be closed. In addition, the degree of opening daytime and / or weekday and / or temperature and / or Seasonally determined. In this way, the invention takes account of different requirements, such as the temperature of the ambient air, holidays, of course, the shop closing times, etc. In order to act on the drive 9 and the multiple drives 9, a controller 15 is provided. The controller 15 may communicate with the respective drive 9 wirelessly or by wire.

Individual or all of the abovementioned parameters are now stored in the control 15, so that the roller blind 6a, 6b sets the desired or required opening degree of the access opening 3. This can be done quite differently from refrigerated shelving to refrigerated shelves or together.

The single roller blind 6a, 6b is composed according to the embodiment of individual heat-insulated roller blinds or of pivotally interconnected thermally insulated roller blind rods together. The housing 1 is designed to be heat-insulating. In contrast to the housing 1, which is constructed of steel or aluminum plates, and on an example intermediate heat insulating layer of foamed plastic, the Rollolamellen or thermally insulated roller poles per se are made of plastic and thereby already have good thermal insulation properties.

These are further increased if individual or all of the roller blinds or roller shutter bars are filled with respect to their enclosed cavity with a foamed plastic. As a result, a thermal insulation of the cool interior of the housing 1 relative to the ambient air can generally be achieved, which regularly avoids dew point undershooting on the outer roller blind surface. Basically, a condensation at this point but also be countered by the fact that the exhaust air of the cooling (air) unit 4 with closed blinds 6a, 6b from the slot on the Lower edge 5 of the access opening 3 - and only then - exits. Of course this is an option and not a mandatory measure.
