[0002] Horizontally guided roller blind for a Gailey of a rail vehicle with concealed lower guide rail

[0003] The invention relates to a Gailey for a rail vehicle and to a rail vehicle with a Gailey comprising a counter unit and a roller blind device, wherein the roller blind device comprises a roller blind with slats aligned vertically in the intended installation position and an upper guide rail and a lower guide rail for guiding the roller blind, wherein the roller blind is arranged above the counter unit.

[0004] Gaileys, also known as galleys or on-board bistros, have long been common on passenger rail vehicles. They traditionally include preparation areas, a sales counter, and tables. Gaileys have also become known, featuring food and drink vending machines for self-service.

[0005] In order to protect goods and equipment from access by unauthorized persons, Gaileys with a counter usually have at least one roller blind with which the space behind the counter can be separated from the passenger area in front of it.

[0006] Roller blinds with horizontal slats, such as those found in homes, are guided on vertical rails on both sides and can be slid upward toward the ceiling. Their lower edge rests on the counter when closed. Another example of a roller blind with horizontal slats is disclosed in WO 2008 / 111934 A1.

[0007] Roller blinds with vertical slats that can be opened and closed horizontally have also become popular. Similar to vertically guided blinds, horizontally guided blinds can be guided by two opposing guide rails. For example, a downwardly open U-profile rail can be installed near the ceiling, and an upwardly open U-profile rail can be embedded in the counter, with the blind running along both U-profile rails. When the blind is open, dirt and water can collect in the upwardly open U-profile rail in the counter.

[0008] Therefore, WO 2019 / 211119 A1 proposes a Gailey according to the preamble of independent patent claim 1, with a counter guide profile arranged above the counter, which is encompassed by a U-shaped roller blind guide. The counter guide profile now projects beyond the counter's work surface, which, on the one hand, prevents spilled liquids from running down the counter, while, on the other hand, providing a small barrier for food and drinks being served.

[0009] The invention is based on the object of proposing a Gailey which is user-friendly and easy to clean.

[0010] This problem is solved by the subject matter of independent patent claim 1. Further developments and refinements of the invention are found in the features of the dependent patent claims.

[0011] A Gailey according to the invention for a rail vehicle for passenger transport comprises at least one counter unit and at least one roller blind device. The at least one roller blind device comprises a roller blind with slats that are vertically aligned in the intended installation position. Furthermore, the at least one roller blind device comprises an upper and a lower guide rail for guiding the roller blind.

[0012] The upper guide rail is arranged above the lower guide rail in the intended installation position. The roller blind is arranged at least partially above the counter unit, which has a storage area, in the intended installation position. Furthermore, the roller blind is designed such that it extends below the storage area of ​​the counter unit, with the lower guide rail being arranged below the storage area of ​​the counter unit. A rail vehicle for passenger transport according to the invention has at least one Gailey according to the invention.

[0013] The counter unit's storage surface forms the top of the counter unit. The counter unit itself can be formed by a worktop, a counter, or a bar counter. The storage surface could also be referred to as a work surface or serving surface.

[0014] The roller blind is guided along the upper and lower guide rails. When properly installed, the upper guide rail forms a substantially horizontal plane, and the lower guide rail forms a substantially horizontal plane when properly installed. The guide rails run substantially parallel to one another and are aligned horizontally. Accordingly, the slats of the roller blind are substantially vertical. The roller blind can therefore be opened or closed horizontally along the upper and lower guide rails.

[0015] When closed and in the intended installation position, the roller blind is guided past a front side of the counter unit in particular, so that it falls below the support surface of the counter unit at least in sections - a lower end of the roller blind is closer to a floor than the support surface of the counter unit standing on the floor.

[0016] The counter unit can be curved. The roller blind is therefore opened and closed horizontally, guided horizontally, and can therefore follow the counter contour. The upper and lower guide rails are then designed to follow the counter contour.

[0017] According to a development of the invention, the lower guide rail is arranged on an underside of the counter unit. The underside of the counter unit is correspondingly aligned opposite to the storage surface of the counter unit. According to a further development of the invention, the roller blind device is designed such that the roller blind is guided hanging in or on the upper guide rail. For this purpose, the roller blind device can have upper guide elements designed to be complementary to the upper guide rail, for example, as sliding elements for sliding in the upper guide rail. The sliding elements can be designed to be complementary to a profile of the upper guide rail. Alternatively, the upper guide elements can also be designed as rolling elements, in particular for rolling on or in the upper guide rail. The rolling elements can be designed to be complementary to a contour of the upper guide rail.The upper guide elements are arranged in an upper area of ​​the roller blind.

[0018] The upper guide rail essentially takes on the weight of the roller blind. This means that additional support of the roller blind by the lower guide rail is not absolutely necessary. The lower guide rail does not have to bear the weight of the roller blind and only has to provide guidance. The lower guide rail can be recessed into the front of the counter unit, for example as a C-rail open to the front (the C-rail is open towards the roller blind), with at least one essentially vertical lower guide element of the roller blind device, for example in the form of an arm pointing towards the counter unit and thus towards the lower guide rail and having a sliding block at its tip, engaging in the lower guide rail.

[0019] In a further development, the lower guide rail is designed as a profile rail that is open at the bottom, in particular as a C- or U-profile rail that is open at the bottom, and in a further development it is embedded in the underside of the counter unit. The lower guide rail then forms a profile guide with a C- or U-shaped cross-section. The C- or U-profile-shaped lower guide rail is incorporated into the counter unit and, in particular, does not protrude from the underside of the counter unit, but forms a recess in the underside of the counter unit. In a simple case, it could be incorporated as a groove in the underside of the counter unit. The opening of the lower guide rail, which is designed as an open profile rail, is open towards the floor on which the counter unit stands. According to a further development, the lower guide rail is arranged in the area of ​​a front side of the counter unit.In particular, the lower guide rail is set into the underside of the counter unit as a downwardly open profile rail in the area of ​​the front of the counter unit. When the counter unit is installed as intended in the rail vehicle, the front of the counter unit faces an area accessible to passengers, a so-called passenger compartment. The opposite rear side of the counter unit faces a space in the Gailey that is only accessible to staff. In a further development, the roller blind is guided at least partially over a front side of the counter unit, in particular over a front edge of the storage area of ​​the counter unit facing the passenger compartment.

[0020] If the roller blind is suspended in or on the upper guide rail, the lower guide rail only needs to guide the roller blind transversely to its direction of movement when opening and closing and also needs to support it against external forces transversely to the direction of movement, for example to prevent access to an area behind the closed roller blind.

[0021] The roller blind device is further developed with lower guide elements which are designed to be complementary to the lower guide rail, at least in sections. For example, the lower guide elements can have sliding or rolling elements designed to be complementary to the profile of the lower guide rail, for sliding or rolling in the lower guide rail. The sliding or rolling elements can be arranged, for example, at the tips of the lower guide elements. According to a further development, the lower guide elements are hook-shaped. The hook-shaped lower guide elements are designed to hook into the downwardly open lower guide rail from below. They can be designed in the form of an L-shaped hook or a U-shaped hook which is open at the top, wherein they engage at least partially in the lower guide rail and are guided in it. For improved running in or out of the lower guide rail.Along the guide rail, sliding elements can be provided at the tips of an arm of the hook-shaped lower guide elements pointing toward the counter unit and thus toward the lower guide rail, which arms extend into the lower guide rail. The sliding elements can, for example, be in the form of a sliding block, made of plastic, for example. The lower guide elements can be made entirely of plastic.

[0022] The lower guide elements are arranged in a lower area of ​​the roller blind and on a side of the roller blind facing the counter unit, the inside of the roller blind.

[0023] In a further development, the lower guide elements are arranged on every second slat. In a further development, the upper guide elements are arranged offset from the lower guide elements and alternately on every second slat.

[0024] The slats of the roller blind can be connected to each other as usual.

[0025] In addition, or alternatively, two immediately adjacent slats of the roller blind can be connected to one another in an articulated manner via upper and / or lower articulated elements. The roller blind accordingly comprises, if appropriate, additional, upper articulated elements for the articulated connection of two slats of the roller blind, which are arranged in the upper region of the roller blind, in particular at the respective upper end of the slats for the articulated connection of the upper ends of the adjacent slats, and / or the roller blind comprises, if appropriate, additional, lower articulated elements for the articulated connection of two slats, which are arranged in the lower region of the roller blind, in particular at the respective lower end of the slats for the articulated connection of the lower ends of the adjacent slats. In a further development, the roller blind comprises upper and lower articulated elements.

[0026] In a further development, the upper and lower joint elements are arranged offset from one another and are alternately connected to the slats.

[0027] A pair of slats connected by lower joint elements is further developed and free of further lower joint elements. A pair of slats connected by upper joint elements is further developed and free of further upper joint elements. However, a pair of slats connected by a lower joint element is connected on both sides to the immediately adjacent slats via upper joint elements, and vice versa. This applies in particular to all slats of the roller blind except for the end slats - these can only be connected to the adjacent slat with a lower joint or with a joint.

[0028] As already explained above, the upper and lower guide elements of the roller blind device are connected to the roller blind. According to a further development, the upper guide elements of the roller blind device are connected to the upper joint elements of the roller blind and / or the lower guide elements of the roller blind device are connected to the lower joint elements of the roller blind.

[0029] The invention has numerous advantages. Because the lower guide rail is arranged below the storage area of ​​the counter unit, i.e. the top of the counter, there is no need for a guide rail on the storage area of ​​the counter unit, creating a continuous storage area without notches or raised areas that is easy to clean and meets the hygiene requirements of commercial kitchens. Unlike roller blinds with horizontal slats, the entire Gailey does not have to be closed; individual sections of the Gailey can also be closed. This means that the counter top is no longer necessary, allowing for a more open design.

[0030] The invention is susceptible of numerous embodiments. It is explained in more detail with reference to the following figures, each of which illustrates an exemplary embodiment. Identical elements in the figures are provided with the same reference numerals.

[0031] Fig. 1 shows schematically a counter unit and a roller blind device of a Gailey according to the invention in cross section through the counter unit and the roller blind device,

[0032] Fig. 2 shows a closed roller blind device according to Fig. 1 from the front.

[0033] In Fig. 1 and Fig. 2, a counter unit 1 and a roller blind device 2 of a Gailey according to the invention for a rail vehicle for passenger transport are shown in two views.

[0034] The counter unit 1 has a top side, a bottom side 7, and a front side 8 facing the passenger compartment. The top side forms a storage area 6 of the counter unit 1. A lower guide rail 5, here in the form of a U-profile groove, is embedded in the bottom side 7.

[0035] The roller blind device comprises a roller blind 2 with vertically aligned and articulated slats 3. The roller blind 2 is suspended from an upper guide rail 4 of the roller blind device. For this purpose, upper guide elements 10 are provided, each of which is partially complementary to the upper guide rail 4 and is guided therein. The upper guide elements 10 are arranged on additional upper joint elements, each of which articulates two slats 3 of the roller blind 2 to one another at their upper ends. Accordingly, an upper guide element 10 is arranged only on every second slat.

[0036] Furthermore, the roller blind device comprises lower guide elements 5, which here are designed as upwardly open, U-shaped hooks for engaging the downwardly open, U-shaped, lower guide rail 5 and are arranged at the lower ends of the slats 3. The lower guide elements 9 are in turn arranged on additional lower joint elements, each of which connects two slats 3 of the roller blind 2 to one another in an articulated manner at their lower ends. Accordingly, a lower guide element 9 is arranged only on every second slat, with the lower and upper joint elements as well as the lower and upper guide elements 9 and 10 being arranged alternately and offset from one another.
