Description

[0001] The invention relates to a floor access module for an elevator system and a conveyor system for conveying people and / or goods into a building.

[0002] Elevator systems are used for the transport of people and / or goods in both new and existing buildings. There is particular interest in modernizing existing properties by retrofitting them with elevator systems, especially by making them accessible for people with disabilities, thus increasing their value.

[0003] However, the construction or retrofitting of elevator systems, especially in existing properties, requires the creation of access options from an elevator cabin to the corresponding floors or residential units, which often do not meet the aesthetic requirements of the residents, e.g. the uniformity of a facade appearance, or compatibility with monument protection.

[0004] For example, CN 111 608 416 A describes an arrangement for adding an elevator outside an existing multi-story residential unit. It describes a corridor with a glass roof that connects the elevator to the residential unit via a door opening in the facade.

[0005] Furthermore, CN 111 824 900 A describes a logistics system for goods located in a building. The logistics system includes a lift system with a rail-guided cabin for contactless goods transport. Furthermore, it describes the provision of an access storage area with its own motor in an apartment, into which goods are stored from the lift system. For this purpose, an access door is opened by the respective motor, and the goods are moved from the lift system into the access storage area with the help of a pneumatic actuator. The goods are then received by a user on the apartment side through a removal door.

[0006] NL 2 002 869 C2 concerns an outdoor lift with at least one lift module, e.g., for construction and renovation work on a building. NL 2 002 869 C2 represents the closest state of the art.

[0007] The disadvantages of the current state-of-the-art solutions are that they involve complicated and costly assembly and inefficient use of installation space. Furthermore, additional motors must be added to the existing solutions to provide access.

[0008] The technical problem is to create a floor access module for an elevator system and a conveyor system for transporting people and / or goods that enables user-friendly access from an elevator system to a building and optimally utilizes the available installation space. The floor access module and the conveyor system for transporting people and / or goods ideally create barrier-free access to a building. The solution preferably takes safety, insulation, space-saving, and aesthetic aspects into account.

[0009] The solution to the technical problem is achieved by the subject matter having the features of the independent claims. Further advantageous embodiments of the invention are set forth in the subclaims.

[0010] A fundamental idea of ​​the invention is to create a modular unit, in particular for use in a conveyor system for transporting people and goods. The modular unit consists of a frame element which forms the structural basis of the modular unit for installation in a facade opening. The frame element has an opening on the elevator side for access to an interior volume of the modular unit and a building-side opening for access from the modular unit to the building and vice versa. Furthermore, the modular unit has a closing element for securing the opening on the elevator side, in particular also as a fall protection element, and a door element for securing the opening on the building side, i.e. towards a building or a residential unit. The closing element does not require its own drive for opening and closing, but is operated as needed by the elevator system, e.g. via an opening mechanism.

[0011] A floor access module for an elevator system is therefore proposed, comprising: at least one frame element for arranging the floor access module in a facade opening of a building, at least one elevator-side closing element for access protection, at least one building-side door element for access protection, wherein the at least one closing element and the at least one door element are operatively connected to the at least one frame element, wherein the at least one closing element can be actuated, in particular opened and closed, by a device of the elevator system.

[0012] The façade opening intended for the installation of the floor access module can be an existing façade opening or one that has been expanded to accommodate the floor module, such as a former window opening or a floor-to-ceiling window opening in the façade of a building. The façade opening can be characterized by a rectangular basic shape and a wall thickness corresponding to the masonry.

[0013] A vertical axis of a Cartesian (reference) coordinate system is preferably oriented against the direction of gravity, in particular parallel to a lifting axis of the elevator system. The longitudinal axis of the coordinate system is preferably oriented normal to the surface of the facade and is oriented from the outside into the building. A transverse axis of the coordinate system is preferably oriented parallel to the surface of the facade. The longitudinal axis and transverse axis are oriented perpendicular to the vertical axis. Directional or locational information mentioned below, such as 'above' or 'below', refers to the orientation of the vertical axis; directional or locational information such as 'elevator side' or 'building side' refers to the orientation of the longitudinal axis; directional or locational information such as 'left' or 'right' refers to the orientation of the transverse axis.

[0014] Preferably, at least part of the floor access module is pre-assembled. In particular, at least part of the floor access module, such as the frame element, can be inserted directly into the facade opening, i.e., without the need for additional on-site assembly steps, such as in-situ assembly of the frame element parts mentioned below. This simplifies and accelerates the installation of the floor access module in the facade opening. Of course, additional fastening, e.g., screwing, of the floor access module to the building or in the facade opening can be carried out on-site.

[0015] The frame element serves as the base of the floor access module. The frame element has at least one elevator-side access opening and at least one building-side access opening, with the elevator-side access opening defined by the end element and the building-side access opening defined by the door element.

[0016] The frame element preferably has a plurality of parts. In particular, the frame element can have an upper part, a left and a right side part and a lower part or threshold part. In particular, at least part of the frame element can also be designed as a casing or decorative panel. In this case, the frame element or the parts described can visually cover the facade opening when used as intended. This improves the user-friendliness of the floor access module. The individual parts of the frame element can be connected to form a unit, for example using screw, rivet or weld connections. The frame element or the parts of the frame element can be made partially or completely, for example, from metal, plastic or wood.

[0017] Further preferably, the frame element is adjustable in at least one dimension. For example, the frame element can have an adjustable region. The adjustable region can be designed such that at least a first part of the frame element is displaced relative to another part of the frame element, thus making the frame element variable in at least one dimension. Thus, the dimensions of the frame element can be easily adapted to the dimensions of a facade opening, such as a predetermined wall thickness of the facade opening.

[0018] Furthermore, the frame element or one or more parts of the frame element, in particular its dimensions, can be designed such that barrier-free access to a building is advantageously created. In this context, it is particularly conceivable for the frame element to have at least one means for aligning the frame element. For a barrier-free, in particular threshold-free, transition from the floor access module into a building, it is advantageous if, for example, the upper side of a threshold part of the frame element is flush with the surface of a floor. Since this varies, for example depending on the floor installed in the residential unit, the transition from the frame element to the building can be alignable. Such a means of alignment can, for example, be designed as one or more screw or foot elements which can be screwed into the frame element on an underside of the frame element.The floor access module can be at least partially in contact with the building via the alignment means or the weight of the floor access module can be at least partially transferred to the building via the alignment means. By screwing a screw element, for example, a threshold height of the frame element can be adjusted such that a barrier-free transition from the floor access module into the building is possible. This increases the user-friendliness of the floor access module. Since the available installation space for the frame element, in particular for the threshold part of the frame element, is limited, e.g. by a distance between a ceiling edge on which the floor access module is placed and the previously explained surface of the floor, the threshold part of the frame element preferably has a height of less than 5 cm. The height can be measured along the vertical axis.

[0019] The functional connection comprises the fact that the at least one closure element is functionally separated from the door element. The closure element can therefore be opened and closed independently of the door element. Furthermore, the frame element can have means for the functional connection to the at least one closure element and the at least one door element. These means can be designed, for example, as a hinge mount, guide rail, locking bar mount, etc. This will be explained in more detail below.

[0020] The closure element serves as an elevator-side shaft closure element for closing the elevator-side opening of the floor access module. In this context, the term "shaft closure element" does not necessarily imply that a covered elevator shaft is provided on the elevator side. Rather, a shaft, within the scope of this disclosure, refers to an area of ​​an elevator system intended for raising and lowering an elevator car, regardless of whether it is physically enclosed or not. When closed, the closure element impedes or prevents access from the floor access module to the elevator system and vice versa. This, in particular, prevents users from falling. This increases the safety and user-friendliness of the floor access module.

[0021] The closing element can be moved from a closed state to an open state by actuation, allowing access from the elevator system or elevator car to the floor access module and vice versa. The closed state can be restored by actuation again. The closing element can correspond to conventional shaft doors.

[0022] When used as intended, the closing element is actuated by a corresponding device in the lift system, in particular a device in the lift car.

[0023] The actuating device is, for example, a component of the car door drive. The force for actuating the closing element can be transmitted to the closing element via a so-called driver blade, which is part of the elevator car. If the closing element is designed in several parts, the closing element can, for example, have a coupling between the parts of the closing element that is designed in such a way that only part of the closing element needs to be actuated in order to open all parts of the closing element. It is also conceivable for the floor access module to have its own drive without its own power supply. The drive can, for example, be electric or pneumatic. The actuating device can supply the drive with power and thus operate it.It is also conceivable for the drive and / or the actuating device to have a corresponding electrical or pneumatic contact, whereby the contact is contacted, for example, when the elevator car stops in front of the floor access module. This has the advantage that the floor access module does not require its own drive to actuate the closing element, or at least does not require its own power supply to actuate the closing element.

[0024] Preferably, the closure element is actuated in such a way that the closure element is positioned in front of the facade when open and / or flush with the facade or frame element when closed. This advantageously results in very little installation space for the closure element in the floor access module or in a minimal installation space for the floor access module in the building. Furthermore, the external appearance of the building is minimally affected. The closure element can be designed, for example, as a sliding element.

[0025] The end element can be connected to the frame element via at least one means of effective connection. For example, the frame element can have at least one guide rail. The guide rail can be arranged, for example, on the upper part of the frame element or on the lower part of the frame element.

[0026] Preferably, the frame element has at least one upper and at least one lower guide rail to securely guide the closure element at both the upper part of the frame element and the lower part of the frame element. The guide rail can guide a translational opening and closing movement of the closure element.

[0027] The guide rail can be designed as a telescopic rail to be as visually unobtrusive as possible when the end element is closed and to reduce the required installation space. In particular, a telescopic rail allows the guide rail of the end element to be no wider than the frame element. Of course, it is conceivable that the means for the effective connection include a connecting piece or similar to guide the end element in the guide rail.

[0028] Alternatively or cumulatively, the end element can also be designed as a folding element or segment element or slat element.

[0029] The closing element preferably also has a reset device, e.g. a spring-cable combination. The reset device can be pre-tensioned by actuating, in particular opening, the closing element. The reset device can, for example, be part of the guide rail and, when the closing element is actuated or opened, counteract any movement of the closing element in order to be pre-tensioned. If the closing element is to be closed, the energy stored in the reset device can be used to actuate or close the closing element again. This is particularly advantageous if the actuating device is not functional, e.g. during a power failure, but the closing element is to be placed in a closed state for safety reasons.

[0030] The door element serves to close the building-side access opening of the floor access module. When closed, the door element hinders or prevents access from the floor access module to the building and vice versa.

[0031] In particular, the door element fulfills the familiar function of a house or apartment door, thereby reducing, for example, the risk of unauthorized access to the building. This increases the security and user-friendliness of the floor access module. The door element is preferably operated by a user, e.g., via a handle set. This allows the door element to be moved from a closed state to an open state, allowing access from the floor access module to the building and vice versa. The closed state can be restored by repeated operation. The door element can correspond to familiar front doors.

[0032] In particular, the end element and / or the door element are adaptable, e.g., to a specified size of the facade opening or the external appearance of the remaining windows and / or doors of the facade. This allows a uniform appearance to be maintained. This is particularly relevant for preserving the monument protection of listed buildings.

[0033] The floor access module described above creates a safe and user-friendly access point between a building or residential unit and an elevator system. It also optimally utilizes the available installation space, with a single façade opening sufficient to create the appropriate access point using the floor access module.

[0034] In a further embodiment, the functional connection between the end element and the frame element is designed as a two-axis sliding connection. Thus, the end element can be guided, e.g. via a suitably designed hinge arm, from a facade end level - or a level offset inwards towards the building interior, which is oriented parallel to the facade end level - in the elevator direction in front of the facade end level and then moved parallel to the facade end level in order to release access to the floor access module. In this case, the end element has the same almost parallel orientation to the facade end level both in a closed and in an open state. In particular, this enables a flush connection between the frame element and the end element. This is particularly advantageous if, for example,Pivoting movements - as carried out with conventional pivoting doors - are not desired due to the limited installation space between the elevator system and the floor access module, and the end element is nevertheless to be arranged in a rebate of the frame element when closed, for example to press the end element against sealing lips in the rebate and thus improve the sealing of the floor access module. The two-axis sliding connection can be designed such that the end element, from a closed state, is guided out of the facade end plane in a first translational partial movement against the longitudinal axis and is displaced in a second translational partial movement along the transverse axis parallel to the facade end plane. The two partial movements can of course overlap at least partially to enable particularly fluid movement.It is also conceivable for one of the partial movements to be carried out at least partially via a rotating pivot arm, with the pivot arm rotating, for example, around an axis, in particular the vertical axis. This synergistically advantageously provides improved protection against water penetration into the floor access module, improves thermal insulation, and provides a space-saving and visually appealing appearance for the floor access module.

[0035] In a further embodiment, the at least one frame element encloses an intermediate space, wherein the at least one closing element and / or the at least one door element delimits the intermediate space. The intermediate space corresponds in particular to the internal volume of the floor access module. It is therefore the internal volume which is delimited by the frame element, the closing element and the door element in a closed state. In particular, access to the intermediate space can be enabled by operating the closing and / or door element. Since the closing and door elements can be operated separately, the intermediate space can be used, for example, by a delivery service to deposit packages without thereby enabling access to the building. This increases the user-friendliness and security of the floor access module.

[0036] The dimensions of the intermediate space – particularly when the end and door elements are closed – can be selected such that the internal height of the frame element along the vertical axis is at least 200 cm, the internal width of the frame element along the transverse axis is at least 80 cm, and the internal depth of the frame element along the longitudinal axis is at least 30 cm. These dimensions have proven particularly advantageous for user-friendly, particularly barrier-free, access. The corresponding external dimensions of the floor access module can, of course, differ from the aforementioned internal dimensions, and in particular, be larger. Furthermore, it can be advantageous, for example, for easy fitting of the floor access module into a facade opening, if the external dimensions of the floor access module are slightly smaller than the dimensions of the facade opening, e.g.The external dimensions of the floor access module can be 1 to 5 cm smaller than the dimensions of the facade opening. Any gaps that may remain between the building and the floor access module after fitting into the facade opening can be closed, for example, by filling it with polyurethane foam. This is particularly advantageous for ensuring the floor access module's insulating effect in conjunction with the building.

[0037] In a further embodiment, the at least one end element is spaced apart from the at least one door element, with the spacing being at least 30 cm. The spacing between the end element and the door element can be measured along the previously described longitudinal axis. The measurement of the distance refers to a closed state of the end element and the door element, in particular to an internal distance. This ensures that the resulting space in the frame element is suitable for storing objects, e.g., beverage crates, up to a dimension of at least 30 cm.

[0038] In a further embodiment, the at least one closure element and / or the at least one door element has a transparent region, wherein a transmittance of the transparent region has a value of at least 0.7. The transparent region can, for example, be designed as one or more windows arranged in the closure element and / or door element. In this way, light can enter the floor access element at least from the elevator side and / or the building side. Preferably, a transparent region of the closure element and a transparent region of the door element are congruent to one another, in particular along the longitudinal axis. It is also conceivable for the closure element and / or the door element to be completely or almost completely transparent. For this purpose, an area of ​​the transparent region can be at least 80% of the area of ​​the access opening closed by the closure element or door element.Preferably, the transparent area is made of a transparent material such as glass or acrylic glass. It is also conceivable, particularly for the closure element, for the transparent area to be formed by translucent openings in the closure element and / or the door element, e.g., as part of a lattice structure. Overall, a transparent area advantageously allows ambient light, especially daylight, to penetrate the building from the outside as unhindered as possible, thus increasing user comfort.

[0039] In this context, transparent means in particular that an image can be produced through the transparent area according to geometric optics with almost no scattering.

[0040] It is also conceivable for the frame element to have at least one window, e.g., a skylight, whereby the window can be arranged, for example, along the vertical axis above the door element and / or the closing element. Such a window is particularly advantageous when, for example, the interior height of the frame element exceeds the height of the closing and / or door element and a remaining interior height of the frame element needs to be bridged.

[0041] The transmittance describes the light permeability of the transparent area for, for example, a light wave, in particular a light wave from the visible spectrum (i.e., light waves with wavelengths from 380 to 750 nanometers). The transmittance value indicates the quotient between the wave intensity in front of the closure or door element and the wave intensity behind the closure or door element. Preferably, the transmittance value of the transparent area is at least 0.8, particularly preferably at least 0.9.

[0042] In a further embodiment, the floor access module has at least one thermal insulation, wherein the thermal insulation ensures a heat transfer coefficient between two sides of the floor access module has a value of less than 2 W / m²K (watts per square meter and Kelvin), particularly preferably a value of less than 1.3 W / m²K. The thermal insulation serves to increase the energy efficiency of the building. In particular, the thermal insulation can reduce the building's heat loss when the floor access module is used as intended. The thermal insulation can be designed, for example, as insulating glass or multiple glazing and can be part of the end and / or door element, for example. The thermal insulation can thus also provide the previously described transparent area at the same time. The thermal insulation is preferably part of the at least one end element and / or the at least one door element.Of course, the thermal insulation can also be in the form of an insulating material such as rigid polystyrene foam, polyurethane or mineral wool and be part of the frame element, the end element and / or the door element, for example. It is also conceivable for the thermal insulation to be in the form of a sealing lip or to include such a lip. The sealing lip can be arranged, for example, between the frame element and the end and / or door element. In particular, the sealing lip can advantageously reduce undirected air exchange between the external environment and the building, as well as the penetration of moisture into the building or the floor access module. In particular, the thermal insulation can be made up of several parts, i.e. consist of several parts that work together. Overall, the thermal insulation described therefore results in increased user-friendliness of the floor access module.Thermal insulation is of course useful both in a situation where an area inside the building is warmer than an external environment, e.g. in winter, and in a reverse situation, e.g. in summer.

[0043] The thermal transmittance, also known as the U-value or K-value, refers to the heat flow, particularly during the intended use of the floor access module, through one or more components of the floor access module, such as the frame element, the end element, and / or the door element, depending on a temperature difference between a first side of the floor access module, e.g., a side oriented toward a heated part of the building, and an opposite side of the floor access module, e.g., a side oriented toward the elevator system or an unheated environment. Methods for determining the thermal transmittance are known to those skilled in the art.

[0044] In a further embodiment, the at least one closure element and / or the at least one door element has locking means. The locking means serves to improve access protection or to securely close the closure or door element with the frame element. The locking means is preferably designed such that it can be repeatedly switched back and forth between a closed state (locking) and an open state (unlocking). In particular, the locking means for the closure element can be designed such that it can be actuated by a device of an elevator installation. Preferably, the locking means comprises a locking device. For example, the locking device comprises at least one bolt with a return spring, wherein the bolt moves into a corresponding detent by means of the return spring, for example. The locking device can, for example,be unlockable using a key or numeric code. Such a locking device, particularly if it is part of the door element, can protect the building against unauthorized access. Furthermore, the locking means can comprise one or more sensors, particularly contact sensors, for monitoring the actuation of the closing and / or door element. The sensor signals can then be provided to a control device of the elevator system to signal successful actuation of the closing element. Thus, the locking means advantageously increases the security of the floor access module.

[0045] In a further embodiment, the at least one frame element has at least one storage device for receiving goods. The storage device serves to improve the delivery of goods, in particular directly to the front door or into the floor access module. In particular, goods can be secured against falling out. For this purpose, the storage device can be designed, for example, as a mailbox. The storage device can be arranged, for example, in or on a side part of the frame element. Preferably, the storage device is arranged such that access from the building to the elevator system is possible even after goods have been positioned in the floor access module, and vice versa. Delivered goods can thus be securely stored in the storage device until they are finally received by the user and can be better protected, for example, against unauthorized access. The storage device is explained in more detail below.

[0046] In a further embodiment, the at least one frame element has at least one retaining device for securing goods. The retaining device serves to improve the delivery of goods, in particular directly to the front door or into the floor access module. In particular, goods can be secured against falling out. For this purpose, the retaining device can be designed, for example, as an elastic tensioning belt. Alternatively, the retaining device can also be designed as an expandable folding or accordion element, e.g. for the purpose of access protection for children. The retaining device can be designed such that the goods are secured by the retaining device against falling out of the floor access module at least over part of the frame element, e.g. over an inner width and / or inner depth of the intermediate space. The retaining device can, for example, be arranged in or on a side part of the frame element.Preferably, the retention device is arranged so that access from the building to the elevator system is possible even after goods have been positioned in the floor access module, and vice versa. Thus, delivered goods can be safely stored by the retention device until their final receipt by the user and, for example, protected from falling out of the floor access module, e.g., when the closure and / or door element is opened.

[0047] In a further embodiment, the at least one frame element has means for drainage. The means for drainage serves in particular to improve the safety as well as to improve the weather resistance of the floor access module. Since the floor access module can be exposed to weather influences such as rain and snow during normal use, it is advisable to drain wastewater from the frame element in order to, for example, reduce the risk of slipping when entering the floor access module and to reduce the risk of mold formation on the frame element or on the floor access module, the elevator system or the building. For this purpose, the means for drainage can be arranged, for example, as a drain or opening in the frame element, in particular in a lower part or threshold part of the frame element, in which wastewater usually collects. It is also conceivable that the means for drainage, for examplecomprises a depression or slope or is designed as such, wherein a gradient of the depression or slope can be oriented toward the previously described drain and / or toward an external environment in order to drain the frame element. The drainage means can of course comprise pipe elements for conveying wastewater. The drainage means can in particular be connectable to a drainage device of the building or the elevator system, such as a sewer pipe or a gutter. The drainage means thus increases the safety and weather resistance of the floor access module.

[0048] In a further embodiment, the at least one frame element and / or the end element and / or the door element has a heating means for frost protection. The heating means serves to ensure the intended functioning of the floor access module, in particular in frosty conditions. Frost can lead to icing on movable components of the floor access module, such as the end element and / or the door element, which impairs functionality. Such icing can be prevented by the heating means. For this purpose, the heating means can be designed, for example, as an electrical heating resistor and arranged along a guide rail of the end element. A corresponding energy supply can be provided by the elevator or the building. The heating means can thus ensure the functioning of the floor access module and advantageously increase user-friendliness.The provision of a heating element is particularly useful if the floor access module is also thermally insulated, as this means that no or less heat loss is available for frost protection.

[0049] In a preferred embodiment, the floor access module has at least one privacy and / or sun protection element. The privacy and / or sun protection element can, for example, be arranged on the frame element and be designed as a blind or roller shutter. Preferably, the privacy and / or sun protection element is integrated into the closing and / or door element and, for example, is arranged as an electrically operable frosted glass film in the transparent area of ​​the closing and / or door element. The privacy and / or sun protection element causes, for example, the previously explained transparent area to become opaque, for example by scattering the incoming light. This is particularly useful if views into the building from outside, e.g. from an approaching elevator car, are to be prevented.

[0050] In a preferred embodiment, the floor access module has a ventilation means. The ventilation means enables air exchange between the floor access module and the environment, thereby removing moisture and allowing fresh air to flow in from outside. In particular, the previously described space between the frame element can be ventilated in this way. The ventilation means can, for example, be designed as a heat exchanger and arranged in a part of the frame element. Alternatively or cumulatively, it is also conceivable for the ventilation means to be designed as a window rebate ventilator in the end and / or door element. The window rebate ventilator can have a wind pressure-dependent flap that closes automatically - i.e., without external drive - at a preset wind pressure value, thereby avoiding unpleasant wind noise.

[0051] In a preferred embodiment, the floor access module has a lighting device. The lighting device serves in particular to illuminate an interior of the frame element, e.g., to illuminate the previously explained intermediate space when there is insufficient daylight, for example, at night. The lighting device can be arranged in the frame element. This can advantageously increase user comfort and safety of the floor access module.

[0052] In a preferred embodiment, the floor access module has a safety device, wherein an emergency mode can be activated by actuating the safety device. The safety device can be arranged on the at least one frame element. The safety device can, for example, be designed as an abseiling device to enable a user to abseil from the corresponding floor of a building in an emergency, such as in the event of a fire. Activating the emergency mode then releases a safety function of the safety device, such as secured abseiling. Actuating the safety device then corresponds to activating the emergency mode. It is also conceivable for the safety device to be designed as an emergency release. In this way, for example, first responders from the fire service can be given an emergency release of the end element and / or the door element in an emergency. Activating the emergency mode can be irreversible, documented, orbe traceable, e.g., by breaking a pane of glass or destroying a seal. This protects the safety device from unauthorized activation. This can advantageously create an escape route for users or access points for first responders, thus increasing the security of the floor access module.

[0053] Further proposed is a conveyor system for conveying people and / or goods into a building, comprising: at least one floor access module according to an embodiment described in this disclosure, at least one elevator system for conveying people and / or goods, wherein the elevator installation has a device for actuating the at least one end element of the floor access module.

[0054] The elevator system is preferably arranged on or in a building, so that at least the device for actuating the at least one closure element can interact, in particular mechanically, with the floor access module. The actuating device has already been explained in the introduction. The elevator system comprises at least one elevator car and at least one lifting device for raising and lowering the elevator car. Of course, it is also conceivable for the elevator system to comprise the at least one floor access module.

[0055] The conveyor system proposed in this disclosure enables particularly space-saving passenger and / or goods transport through the use of a floor access module according to an embodiment described in this disclosure, since little installation space is required to create access from the elevator system into the building. This allows the elevator system, for example, to be arranged in the immediate vicinity of the building's facade, and an elevator car to be guided along the facade. The technical effects and advantages mentioned for the floor access module thus also apply accordingly to the conveyor system according to the invention.

[0056] Particularly preferably, the elevator system is designed as a shaftless elevator system, e.g., as an elevator system with hydraulically extendable telescopic cylinders for raising and lowering the elevator car. In particular, the elevator system is designed as an external elevator system, wherein the external elevator system can be arranged in the immediate vicinity of an external facade of a building. This enables the conveyor system to transport people and / or goods from an external environment, e.g., the street, directly into a building, in particular directly to the corresponding residential unit, without the people or goods having to enter the building to use the elevator system. This increases the user-friendliness of the conveyor system. A conveyor system designed in this way with an external elevator system is particularly effective, especially in conjunction with a thermally insulated and / or transparent floor access module—as previously described for embodiments of the floor access module.

[0057] The elevator system is preferably designed or arranged such that access to the elevator system from the surrounding area, e.g., from the street, is barrier-free, in particular threshold-free. Barrier-free refers in particular to a threshold height at the transition between the street and the elevator system, or between the elevator system and the floor access module or the building, being less than 20 mm. Furthermore, a threshold or threshold plane of the elevator system can be aligned almost parallel to a corresponding plane of a threshold part of the floor access module when an elevator car stops as intended at the floor access module, so that access from the elevator system to the floor access module and thus to the building is barrier-free. This increases the user-friendliness of the conveyor system.

[0058] Of course, the elevator system can also be designed as a conventional elevator system.

[0059] It is also conceivable for the floor access module and / or the elevator system to include gap closure means between the elevator system and the floor access module. The gap closure means can, for example, be rigid and protrude from a facade level as a step. It is also conceivable for the gap closure means to be designed as an extendable step, extendable, for example, by an electric motor. This can advantageously increase user-friendliness and safety, as the gap closure means creates a flush transition from the elevator system to the floor access module.

[0060] In a further embodiment, the conveyor system comprises a device for identifying a user and a control device for controlling access protection, wherein the control device is designed to carry out at least one of the following steps: Identifying a user, whereby an access authorization is determined depending on the identified user, actuating at least one closing element of a specific floor access module depending on the specific access authorization.

[0061] The device for identifying a user can, for example, be designed as a near-field communication system and be arranged on a side of the elevator car that is accessible before entering the elevator car. It is also conceivable for the identification device to be arranged on a facade of the building. The identification of a user preferably takes place automatically, i.e. without corresponding authorization from a person. For example, a user can identify themselves by means of a code, which can be designed, for example, as a chip or RFID tag. The identification device can have means for reading and verifying the code and thus identifying the user. A signal representing the identification of an authorized user can be passed from the identification device to the control device and further processed there.

[0062] The determination of access authorization and / or the actuation of the closing element can be carried out using the control device. For example, predetermined assignments for various identified users and associated floor access modules can be stored in the control device. If, for example, a delivery person is identified as a user, the access authorization can be determined as a "delivery person" access authorization for a specific floor access module of the conveyor system. The access authorization can then comprise authorized use of the elevator system and authorized access to a specific floor access module, e.g., the floor access module on the first floor. This allows the delivery person to position goods to be delivered in the specific floor access module without having to gain access to the building or other floor access modules. Conversely, if an unauthorized user is identified, the access authorization can be denied or revoked.cannot be determined at all. In other words, it is impossible for an unauthorized user to use the conveyor system. This increases the security of the conveyor system.

[0063] Preferably, the conveyor system also includes a documentation device for documenting the identified user and / or for documenting the specific access authorization. The documentation device can include a corresponding memory module for storing the data to be documented and be part of the identification device. This advantageously allows the previous uses of the conveyor system to be tracked, which in turn increases the security and user-friendliness of the conveyor system.

[0064] Of course, it is also conceivable, alternatively or cumulatively, for a person, e.g., a resident of the building, to manually identify a user. The identification device could include, for example, an appropriate intercom or video intercom system. Access authorization can then be determined using the control device or, for example, by pressing a corresponding button.

[0065] Preferably, determining the access authorization includes the corresponding locking element being actuated or unlocked only when the elevator car stops at the specific floor access module. Thus, when an elevator car passes another floor access module, e.g., at a different floor, the corresponding locking element does not need to be actuated. This ensures that the identified user is granted access exclusively to the specific floor access module. Of course, the access authorization can include the corresponding locking element being actuated again, in particular being locked, when the elevator car starts moving again after a stop.

[0066] In summary, the embodiment described here allows access to the elevator system or to a specific floor access module to be individualized, thereby simultaneously increasing the safety of the conveyor system and user-friendliness.

[0067] The conveyor system particularly preferably has at least one storage device for receiving goods. The storage device can, for example, be arranged - as explained above - in the frame element of the floor access module. The storage device is preferably arranged in the elevator car of the elevator system. The storage device can be electronically locked and / or coded, e.g. via a numerical code. Furthermore, the storage device can be managed by a management device. The management device can, for example, be designed as the previously explained control device or as the device for identifying a user and can manage the storage device in such a way that the storage device can only be used or operated by a previously determined, authorized user. For this purpose, the identified user can be assigned access authorization to open and close the storage device.The access authorization can be designed in such a way that a user is provided with a numerical code for operating the storage device, in particular a specific storage compartment of the storage device. The storage device preferably has a plurality of storage compartments, in particular of different sizes, wherein, for example, the control device can assign a specific storage compartment to an authorized user, in particular only temporarily, i.e. for example for an operating process. Alternatively or cumulatively, the storage device can be linked for data purposes to an external server device, e.g. to software from service providers who deliver mail, parcels or goods. This can ensure that, for example, a resident is automatically informed by the delivering service provider via the external server about a delivery of goods, e.g. by email.

[0068] This filing system can be managed by a management device in such a way that a specific filing compartment can only be operated, and in particular opened, by an authorized person. Since the filing compartments of the filing system can have different sizes, the above-mentioned management device can flexibly assign individual filing compartments to individual users. Furthermore, the management device can be linked to the control device explained above or be designed by it. In addition, the management device can be linked to the software of service providers, whereby the service providers deliver, for example, mail, parcels or goods. This means that a user not only receives secure filing within the conveyor system, but can also be notified of a delivery via the software of the delivering company.

[0069] The invention is explained in more detail using exemplary embodiments. The figures show: Fig. 1 shows an embodiment of a conveyor system according to the invention, Fig. 2 shows a further embodiment of a conveyor system according to the invention, Fig. 3 shows an embodiment of a floor access module according to the invention and Fig. 4 shows a plan view of a further embodiment of a floor access module according to the invention.

[0070] In the following, the same reference symbols refer to elements with the same technical features.

[0071] Fig. 1 shows an embodiment of a conveyor system 20 according to the invention with an embodiment of the floor access module 1 according to the invention and a shaftless elevator system 20 with an elevator car 23 guided on two columns S and liftable by hydraulic telescopic cylinders. In the Fig. 1 In the situation shown, the elevator car 23 is located just above a first floor E1. A floor access module 1 is located on each floor E1, E2, E3, or each upper floor of the building G. The floor access modules 1 shown serve as access to the building G and vice versa when the elevator car 23 stops.

[0072] The Cartesian, right-handed coordinate system X, Y, Z shown in Fig. 1 to Fig. 5 is stationary and serves for orientation. The longitudinal axis X is oriented from an external environment 100 into the building G. The vertical axis Z is oriented opposite to the direction of gravity. The transverse axis Y is oriented perpendicular to the longitudinal and vertical axes X, Z and parallel to the exterior facade of the building G.

[0073] The floor access modules 1 are arranged one above the other—spaced apart—along the vertical axis Z in a designated façade opening F of the building G. The floor access modules 1 each extend over the wall thickness W of the exterior façade or of the building G. The floor access modules 1 therefore efficiently utilize the installation space provided by the respective façade opening F for access from the elevator car 23 to the building G.

[0074] Fig. 2 shows a further embodiment of a conveyor system 20 according to the invention and in addition to Fig. 1 how several users N, including a wheelchair user, enter an elevator car 23 on the street side in order to reach building G via the floor access module 1 shown.

[0075] For the sake of simplicity, a shaft around the street-side access area, particularly to prevent accidents and to protect the lift system against unauthorized access, is included in the Fig. 1 and 2 not shown.

[0076] Fig. 3 shows an embodiment of a floor access module 1 according to the invention. For easy assembly, the floor access module 1 can be at least partially pre-assembled. Thus, the floor access module 1 according to Fig. 3 a frame element 4 as a structural mechanical base body, whereby the frame element 4 is completely pre-assembled. The frame element 4 consists of four metal parts, namely an upper part 15, a sleeper part 16 as well as a left side part 17 and a right side part 18. For a better overview, the parts are only shown in Fig. 3 with the corresponding reference numerals. Parts 15, 16, 17, 18 of frame element 4 can be connected to one another, e.g., via welded joints (not shown), before insertion into the facade opening F. This makes it easy to reduce the effort required to insert the floor access module 1 into the facade opening F, since any assembly steps no longer need to be performed on-site.

[0077] Furthermore, the frame element 4 according to Fig. 3 an intermediate space 5. The intermediate space 5 corresponds to the internal volume of the frame element 4. The following dimensions, for example, have proven advantageous for the intermediate space 5: The intermediate space 5 preferably has an internal height H of at least 200 cm along the vertical axis Z. Furthermore, an internal width B of the intermediate space 5 is preferably at least 90 cm along the transverse axis Y. An internal depth of the intermediate space 5 of at least 30 cm can be dimensioned along the longitudinal axis X. The internal depth of the intermediate space 5 preferably also corresponds to a spacing 6 between an end element 2 and a door element 3 of the floor access module 1. The external dimensions of the floor access module 1 can of course exceed the aforementioned internal dimensions, wherein the external dimensions of the floor access module 1 are limited by the available installation space in the facade opening F.

[0078] One in Fig. 3 The door element 3 shown is designed as a front door with a locking device 26 or door lock. The door element 3 delimits the space 5 of the frame element 4 to an interior of the building G (not shown) and secures a building-side access to the floor access module 1. The door element 3 is made of heat-insulating glass. The door element 3 is thus largely transparent—i.e., it has a transparent area 7 so that daylight from outside (e.g., from the environment 100) can enter the building G.

[0079] The Fig. 3 The insulating glass of the door element 3 shown also provides thermal insulation 8 of the transparent area 7 or of the entire floor access module 1. The thermal insulation 8 of the door element 3 is designed such that the thermal transmittance value is less than 1.3 W / m²K (watts per square meter and Kelvin). The value can be determined in intended use, for example, between a first side 81 of the floor access module 1 and a further side 82 of the floor access module 1. The first side 81 can, for example, be the side of the door element 3 facing the building, and the further side 82 can be the side of the door element 3 facing the intermediate space 5 (cf. Fig. 4 ).

[0080] According to Fig. 3 A storage device 11 and a retaining device 10 are arranged in the left side part 17 of the frame element 4. The storage device 11 is designed as a mailbox. The storage device 11 allows goods to be stored safely without the goods to be stored blocking the intermediate space 5 or obstructing access from the elevator system 21 to building G and vice versa.

[0081] The retaining device 10 is designed as a tensioning belt and can be used to secure goods in the intermediate space 5. Of course, goods, e.g., beverage crates, can also be stored in the intermediate space 5 and then secured in the intermediate space 5 with the help of the tensioning belt to prevent them from falling out of the tier module 1.

[0082] Furthermore, according to Fig. 3 A drainage device 13 designed as a drain can be arranged in the sill part 16 of the frame element 4. An opening of the drain can be divided into several slots by a grid. The drainage device 13 can be connected to a drainage system of the building, e.g., a gutter, via appropriate pipes, either above or below the plaster.

[0083] According to Fig. 3 The closing element 2 is designed as a two-part, glazed sliding door and delimits the intermediate space 5 of the frame element 4 to an elevator-side environment 100 or to the elevator system 21. Because both parts of the closing element 2 are glazed or designed as glass panes, the closing element 2 also has a transparent area 7. The closing element 2 is arranged on the frame element 4 via a guide rail 25. The sliding doors of the closing element 2 can be moved along the transverse axis Y via the guide rail 25. This is shown in Fig. 3 indicated by arrows. When opened, the sliding doors of the closing element 2 are positioned in front of the facade of building G (see Fig. 4 ).

[0084] The guide rail 25 can be heated by a heating element 12 designed as a heating resistor. For this purpose, the heating element 12 is arranged in front of the guide rail 25. This ensures trouble-free operation of the closing element 2, for example, even in winter or during frosty conditions (see. Fig. 3 ).

[0085] By operating the end or door element 2, 3, these can each be moved from a closed state to an open state in order to enable access from the elevator system 20 to the building G via the floor access module 1.

[0086] To operate door element 3, the locking device 26 can be unlocked with a key, for example. This protects against unauthorized access to building G via the floor access module 1. The door element 3 can be operated alternatively or cumulatively, for example, via a handle set (see. Fig. 3 ).

[0087] In its intended use, the end element 2 can only be actuated by a device 22 of the lift system 21 designed as a driver blade (cf. Fig. 4 ). When an elevator car 23 stops in front of the floor access module 1, the drive blade unlocks a means for locking the end element 2 and sets the sliding doors of the end element 2 in a sliding movement along a guide rail 25, so that the end element 2 is moved from a locked state to an open state. When the end element 2 is in the open state, a user N, for example, can then get from the elevator car 23 into the intermediate space 5. Furthermore, the user N - assuming appropriate access authorization - can open the door element 3 and thus enter the building G. If the elevator car 23 starts moving again, the end element 2 is again actuated and locked by the device 22 of the elevator system 21 (cf. Fig. 4 ).

[0088] Fig. 4 shows a plan view—i.e., a perspective opposite the vertical axis Z—of another embodiment of a floor access module 1. The floor access module 1 is fitted into a facade opening F of a building G. Furthermore, an elevator car 23 of an elevator system 21 is arranged in front of the building G, which elevator car can be raised and lowered along the vertical axis Z.

[0089] On the building side, the floor access module 1 has a door element 3 designed as a two-part hinged door. On the elevator side, the floor access module 1 has a closing element 2 designed as a two-part sliding door.

[0090] To better explain the functionality of the floor access module 1, the floor access module 1 is shown in a closed state in the right-hand part of the figure and in an open state in the left-hand part of the figure. The actuating device 22, designed as a driver blade, has already actuated the end element 2 of the floor access module 1 in the left-hand part of the figure, but in the illustrated situation is still engaged in a designated opening in the end element 2. The two parts of the figure are separated from each other by a dash-dot line.

[0091] According to the left figure area in Fig. 4 one leaf of the door element 3 is pivoted open by 90 degrees. The pivoting movement required for actuation is shown by a dashed line. In a closed state (right-hand area of ​​the figure), the door element 3 is completely recessed into the frame element 4. In particular, the frame element 4 can have a corresponding rebate to accommodate the door element 3 in the access opening on the building side. This can enable a flush finish between the door element 3 and the frame element 4 on the building side. This is particularly useful with regard to the arrangement of sealing lips for sealing the floor access module 1. The sealing lips can then be arranged, for example, on the edges of the door element 3 and / or, for example, in the rebate of the frame element 4.

[0092] The end element 2 is also shown in the left part of the figure in an open state. The end element 2 is arranged in front of the outer facade of the building G. A functional connection between the end element 2 and a frame element 4 of the floor access module 1 is designed as a two-axis sliding connection 25, 27. The two-axis sliding connection 25, 27 has Fig. 4 a hinge arm 27 guided in a two-axis guide rail 25. The hinge arm 27 is movably mounted in the guide rail 25. As a result, the end element 2 is displaced via the two-axis sliding connection 25, 27 both along the longitudinal axis X and along the transverse axis Y.

[0093] By actuating the end element 2 again, a closed state is then achieved - as shown in the right-hand part of the figure - in which the end element 2 is flush with the outer side of the frame element 4. Due to the two-axis sliding connection 25, 27, no pivoting movement of the end element 2 is necessary to create the flush closure - in contrast to the pivoting movement of the door element 3 required for this purpose. This way, the gap between the elevator car 23 and the floor module 1 can be kept small. In particular, the guide rail 25 and the hinge arm 27 are not visible from the outside in a closed state and are arranged, for example, in an upper part 15 and / or threshold part 16 of the frame element 4. This way, a uniform appearance of the outer facade of the building G can be ensured. The two-axis sliding connection 25, 27 can also ensure that the end element 2, for example,is arranged in a fold of the frame element 4.

[0094] The gap between the floor access module 1 or frame element 4 and the elevator car 23 can be closed using a gap-closing means 28 designed as a step. For this purpose, the step can be arranged on the frame element 4 and can be extended as needed—for example, when the elevator car 23 stops in front of the floor access module 1. It is also conceivable for the step to be part of the elevator car 23 and to be extended during a stop. Bezugszeichenliste
