DETAILED DESCRIPTION

[0051] Terms such as top, bottom, right, left, inside, or outside refer to the respective illustrated position in the figures and are to be understood or viewed relatively in the case of movementsin particular rotationsof the illustrated elements in space.

[0052] A building 1 is illustrated in FIG. 1. The building 1 has a rectangular outline here.

[0053] The building 1 comprises, by way of example here, six stories plus the ground floor. The building 1 can also comprise greater or fewer stories. The building 1 comprises a roof, which is embodied here by way of example as a flat roof. The building 1 can also comprise a pitched roof 3 having inclined pitched roof surfaces, for example, a saddle roof or shed roof.

[0054] The building 1 can also have a different geometric outline. The faades of the building visible in FIG. 1 are each embodied as element faades here. They thus consist of a plurality of faade elements 2a, 2b. These are embodied as rectangular here and are arranged in rows one over another and in columns adjacent to one another.

[0055] A part of the faade elements 2a, 2b can comprise at least one plate on their outside. This plate can in turn be formed as a glass plate, for example, as an insulating glass plate, in a part or all of the faade elements 2a, 2b.

[0056] At least one or moretwo of the faade elements here 100a, 200beach comprise a device (not shown here) for sending or receiving letters and parcels, wherein the device is designed such that the letters or parcels can be picked up or delivered by an unmanned air vehicle (in short device for receiving and sending mail items using an unmanned aircraft).

[0057] These faade elements are preferably equipped for this purpose with an outer leaf 102 pivotable around a horizontal tilt axis and an openable inner leaf. An exemplary structure is explained hereinafter with reference to FIGS. 12 et seq.

[0058] The faade elements 100a, 200b are equipped with an openable and closable outer leaf 102, which comprises a device 103 for receiving and sending parcels using an unmanned aircraft. These faade elements 100a, 200b can be installed at nearly any point of the faade of the building and replace a faade element otherwise provided at this point without a device for sending or receiving a mail item using an unmanned aircraft, wherein the device is designed such that the mail item can be retrieved or delivered by an unmanned aircraft.

[0059] It is provided as a particularly advantageous design that the faade elements without a device for sending and receiving mail items using an unmanned aircraft may not be differentiated or may not be differentiated significantly from the faade elements 100a, 200b having an outer leaf 102 having a device for receiving and sending mail items using an unmanned aircraft.

[0060] A faade having multiple faade elements 2a, 2b; 100a, 200b is provided, of which a part of the faade elements 2a, 2b is or are formed without a device for sending and receiving mail items using an unmanned aircraft, and wherein at least one of the faade elements 100a, 200b, is formed having a device for sending and receiving mail items using an unmanned aircraft, wherein the appearance of these various faade elements is identical or essentially identical viewed from the outside.

[0061] For this purpose, the pivotable-open outer leaf 102 having the device 103 for receiving and sending mail items using an unmanned aircraft has, for example, the same area dimensions as the other faade elements without a device for receiving and sending mail items using an unmanned aircraft. Moreover, it can advantageously be provided that the pivotable-open outer leaf having a device for receiving and sending mail items using an unmanned aircraft has, for example, the same outer surface plate, which is oriented toward the building exterior, as the other faade elements without a device for receiving and sending mail items using an unmanned aircraft.

[0062] Preferably, the faade elements 100a, 200b having the device 103 for receiving and sending mail items using an unmanned aircraft each comprise an openable and closable inner leaf 109 and an openable and closable outer leaf 102, wherein these are preferably designed as pivoting, sliding, or rotating leaves.

[0063] However, the design of at least the outer leaf 102 as a pivoting leaf having a horizontally aligned pivot axis is particularly preferred, since such a pivot axis most easily enables a horizontally aligned landing station 104 for the drone 101 and/or a pickup station 106 for depositing and/or picking up of the mail item by a drone 101 to be formed.

[0064] From a specific building height, drones 101 can approach the individual elements of windows, doors, or faades in flight without endangering persons located in front of or in the vicinity of the building 1. Elements of windows, doors, or faadeslike the second element of a window, door, or faade 200b close to the ground, in contrast, can theoretically also be approached in flight, butif this is not permittedat least can be approached, for example, by autonomous vehicles on the ground.

[0065] Only the faade element 100a is described in greater detail hereinafter. The faade element 200b close to the ground can be constructed identically thereto.

[0066] A detail of the faade 2 of the building 1 from FIG. 1 is shown three-dimensionally in FIG. 2. The detail of the faade 2 comprises the faade element 100a having the device for receiving and sending mail items using an unmanned air vehicle. This faade element 100a is arranged here essentially in a plane with the faade outer surface of the building 1 and thus meets extremely high aesthetic requirements. The faade element 100a according to the invention having the device 103 advantageously does not stand out from other elements such as the other faade elements or perhaps even windows or doors of the building 1 without a device 103, and thus has an identical appearance (for example, a glass surface in a glass faade here).

[0067] The faade element 100a having the device 103 for receiving and sending mail items using an unmanned aircraft is preferably formed essentially flush with the remaining faade toward the outside and/or toward the inside of the building 1.

[0068] The faade element 100a according to the invention having the device 103 for receiving and sending mail items using an unmanned aircraft can form a unit insertable into a building opening alone or can form a part of a higher-order subunit of the faade, which can also include, for example, a window 115 or the like (FIG. 20).

[0069] The faade element(s) 100a having the device for receiving and sending mail items using an unmanned aircraft can be arranged at an arbitrary point of the building 1, thus, for example, at individual living units or offices or in stairwells, so that the access by multiple access-authorized persons is possible here.

[0070] The outer leaf 102 of the faade element 100a having the device for receiving and sending mail items using an unmanned aircraft is preferably provided with a pivot mechanism for pivoting around a horizontal pivot axis.

[0071] The outer leaf 102 of the faade element 100a having the device for receiving and sending mail items using an unmanned aircraft can, according to one advantageous design, comprise a thermally-insulated frame having seals, which accommodates a planar element, for example, a glass plate or glazing.

[0072] The outer leaf 102 of the faade element 100a having the device for receiving and sending mail items using an unmanned aircraft can furthermore comprise fitting parts, for example, rotating hinges, stay arms, and locking elements. Such fitting parts are known per se, so that a detailed description is omitted. Reference is made by way of example to the following patent literature at this point: U.S. Pat. Nos. 3,722,142; 2,648,878; EP 3 006 658; EP 1 348 830; EP 1 739 263.

[0073] In addition, motorized drives can be used to actuate the outer leaf 102. These include, for example, chain drives or drives which act directly or indirectly on the stay arms. The following opening kinematics are preferably implemented with respect to the element 100a of a window, door, or faade: tilt sash (horizontal axis rotating hinges at the bottom), folding sash (horizontal axis rotating hinges at the top), or lower-fold sash windows (for example, having rotating functions in the stay arms).

[0074] The faade element 100a is shown partially open in FIG. 3.

[0075] The faade element 100a of FIG. 3 comprises the device 103 for receiving and sending mail items using an unmanned aircraft on an inner side of the outer leaf 102. This device 103 can be provided with a landing region 104 for a drone 101 (not shown here). The device 103 can also be embodied without the landing region 104. It then instead has to have a deposit and pickup region for the mail items. This can be formed smaller with respect to the area than a landing region but otherwise constructed similarly; in this case the drone 101 would set down the transport material on the outer leaf or throw it thereon from a low height.

[0076] For the reliable depositing of the transport material, however, landing of the drone 101 on the landing region 104 of the device 103 is preferred. In addition, landing the drone 101 on the landing region 104 has the advantage that the drone 101 not only can deliver the transport material, but rather can also pick up the transport material particularly easily. The faade element 100a according to the invention is thus not only available for receiving the transport material, but rather also for sending the transport material.

[0077] The faade element 100a is shown in a fully open state in FIG. 4. Furthermore, the device 103 for accommodating a transport material T is shown in a maximally open state. The transport material T is presently being delivered or retrieved by a drone 101.

[0078] According to one advantageous design, the device 103 can comprise a telescoping thrust device 105, which enables the landing region 104 to be positioned somewhat more spaced apart from the building 1 or spaced apart from the faade 2 than would be possible solely with a pivoting leaf without telescoping thrust device 105.

[0079] It can be provided according to one advantageous variant of this design that the thrust direction of the thrust device extends in parallel to the outer leaf 102. This is because, on the one hand, the thrust device can be arranged particularly simply on the pivoting leaf in this way. Moreover, extension and retraction of the thrust device 105 in particular in the horizontal only requires a relatively minor force, so that it is possible to implement an automatically extendable and retractable thrust device using a simple electromotive drive. The drive is not shown here. An optional control device is also not shown, using which the operation of the device 103 or the entire element is controlled in dependence on the flight movements for depositing and retrieving shipments (for example, the folding out and folding in of the outer leaf 102 and the extension and retraction of the thrust device 105).

[0080] At least one type of telescopic rail guide having multiple telescoping rails (not shown in FIG. 5) can be provided between the thrust device 105 and the outer leaf as the thrust device 105. According to another variant, the thrust device 105 comprises multiple plates telescopically extendable by displacement in relation to one another. The thrust device is implementable in various ways.

[0081] In this way, the drone 101 does not have to fly excessively close to the building 1, but rather can maneuver and land safely spaced apart somewhat therefrom. Safe landing and takeoff with reduced risk of collision of the drone 101 with the building 1 is thus ensured. The thrust device 105 can be produced, for example, from additional thermal insulation plates, which can be provided with guides known from the prior art. These can be designed, for example, like drawer guides for items of furniture and are preferably designed to be movable by an electric motor.

[0082] The landing region 104 can be formed as a separate, stationary pickup element 106 for the transport material. The pickup element 106 can be formed as a type of shell, as an open box, or as a closable container (see FIG. 3 to FIG. 5). The box can have one or two folding covers, which can be opened or closed by electric motor as needed. The cover surfaces can form additional landing surfaces for the drone 101.

[0083] In FIG. 5, the thrust device 105 is shown in a middle positioni.e., between fully extended (see FIG. 4) and fully retracted (see FIG. 3). The receptacle element 106 is shown partially open. The device 103 in FIG. 5 is thus prepared either for a landing approach of the drone 101 (not shown here, see FIG. 4) or the drone 101 has just taken off and the device 103 is prepared for closing the faade element 100.

[0084] In another embodiment variant of the inventionwhich is constructed somewhat more simply but is also less versatilethe faade element 100a comprises a folding leaf as the outer leaf 102, on which the drone 101 can land directly. The outer leaf 102 of the faade element 100a can then comprise an opening permitting the transport material T to be placed directly through the outer leaf 102 into the pickup element 106.

[0085] The outer leaf 102 can also have a thrust device 105 having landing region 104 and/or pickup element 106, however. In FIG. 6, the extension is illustrated by the arrow.

[0086] FIGS. 7 to 9 show preferred embodiments, wherein a pitched roof window (element) 100 for opening and closing a pitched roof opening of a pitched roofi.e., in particular a pitched roof having an angle of inclination between 10 and 80 to the horizontalis provided with an outer leaf 102, which comprises a device 103 for receiving and sending mail items using an unmanned aircraft.

[0087] This device 103 for receiving and sending mail items using an unmanned aircraft preferably also again comprises the or a telescoping thrust device 105 having a landing region 104 and/or a pickup element 106, using which the landing region 104 or the pickup element 106 can be extended telescopically in the direction of the arrow out of the plane of the building or faade to provide a spaced-apart position. In this way, the outer leaf 102 of the pitched roof window element 100a can manage without a separate opening, which improves the leak-tightness of the pitched roof window element 100a.

[0088] In this case, the embodiment variants in FIGS. 7, 8, and 9 each comprise a closed outer leaf 102 without direct opening for the transport material. The opening directly in the outer leaf 102 is thus omitted. Furthermore, the respective outer leaf 102 of the respective element 100a of a window, door, pitched roof, or faade comprises circumferential seals (not shown here) similarly to a window leaf without device 103.

[0089] Moreover, a landing region 104 is provided. This can again be provided on a telescopic thrust device 105. The landing region 104 can be formed as a landing platform or as a landing framework. The landing region 104 can moreoverto avoid leak-tightness problems and to permanently protect it well against weather influencesbe provided as extendable on the lower side (with respect to the folded open state) of the outer leaf 102.

[0090] It can be formed like a type of drawer, which is preferably arranged displaceably below the outer leaf and is extendable out of the outer leaf in a horizontal position thereof (FIGS. 7, 8). It can be implemented similarly on a window element or a faade element (FIG. 10, FIG. 11). It is also conceivable to provide a pivot element instead of a thrust device to fold out the landing region. The mechanism for extending landing region can also be designed to execute a combined or overlaid linear and pivot movement.

[0091] The respective landing region 104 can comprise a respective pickup element 106 adapted to different landing frameworks of the drone 101 used, which can be formed, for example, as a type of depression in the landing region 104. In addition, the respective device 103 respectively comprises a telescopic thrust device 105. The thrust device 105 can comprise a sliding guide (see FIG. 11) or a roller guide (see FIG. 10).

[0092] In each of FIG. 7 and FIG. 10, the inside of the outer leaf 102 comprises a housing 107 for accommodating the device 103, in particular the landing region 104 and the thrust device 105. In this manner, these components are housed well protected in the retracted state and/or in the closed state of the outer leaf 102. This housing can comprise a flap K (FIG. 9), which enables a mail item to be inserted into the housing and/or to be removed therefrom. This flap K can already be considered to be the inner leaf in terms of the application. However, it is also conceivable to additionally provide a further inner leaf on the pitched roof.

[0093] In the preferred embodiment variants of the element 100a for a window, door, pitched roof, or faade elementshown first by way of example on the pitched roof element 100a for the pitched roof according to FIGS. 7, 8, and 9the respective element 100a of a window, door, pitched roof, or faade can respectively comprise an intermediate space 108 for accommodating the housing 107 and/or the landing region 104 and/or the thrust device 105 and/or the receptacle element 106 (not shown here)i.e., essentially the device 103.

[0094] Moreover, the intermediate space 108 can be designed and used for temporarily storing the mail items. The intermediate space 108 can also comprise the housing 107.

[0095] The intermediate space 108 comprises an inner leaf 109 in addition to the outer leaf 102. The inner leaf 109 hassimilarly to the outer leaf 102the properties of a window sash, which is to be opened to remove and/or place the transport material in the building 1.

[0096] A type of airlock is thus formed. It can be designed in such a way that advantageously in dependence on the approach or takeoff of the drone 101, only the outer leaf 102 or only the inner leaf 109 of the element 100 for a window, door, pitched roof, or faade can be opened. The airlock at least enables in a simple manner only a small amount of heat to leave or reach the building 1 during the approach or the takeoff of the drone 101, whereby the element 100a for a window, door, pitched roof, or faade element can overall have good thermal insulation properties, which can also meet elevated standards up to a passive house standard.

[0097] The inner leaf 109 can preferably also terminate flush with the inner wall of the building 1 or the inside of the faade 2. The element 100a for a window, door, pitched roof, or faade element according to the invention thus essentially has the same structural depth as the outer envelope of the building 1 or the wall of the building 1. The advantage of this inner leaf 109 is that during approach of the drone 101, when the outer leaf 102 opens, the interior of the building 1 is still secured against external influences.

[0098] In this case, the inner leaf 109 does not have to have the high requirements for thermal insulation properties, leak tightness, and break-in resistance like the outer leaf 102, since the inner leaf 109 is only briefly open for the transfer procedure of the transport material. To ensure increased break-in resistance of the element 100a for a window, door, pitched roof, or faade element, however, it can be advantageous to make the inner leaf 109 break-in resistant, since the outer leaf 102 could be able to be manipulatedwith malicious intentby the control of the drone 101. An increased break-in resistance of the element 100a for a window, door, pitched roof, or faade element thus particularly advantageously results.

[0099] The inner leaf 109 and/or the outer leaf 102 preferably each comprise a sash 113, 111. This respective sash 113, 111 preferably encloses or frames a planar element in each case. This planar element can be formed as a plate, in particular as a glass, plastic, or metal plate.

[0100] One preferred embodiment variant of an intermediate space 108 is illustrated in FIG. 12.

[0101] On the right side of FIG. 12the building outside herean outer window element is located having a lower frame spar shown in section of a fixed frame 110 and a sash spar of the frame 111 of the movable outer leaf 102. The outer leaf 102 may be opened outwardi.e., in respective FIG. 12 or 13 to the rightby a fitting (not shown here). An insulating glass pane is arranged in the sash 111 here.

[0102] On the left side of FIG. 12i.e., oriented toward the interior of the building 1a fixed frame 112 is also located in flush arrangement, which is fixedly connected to the masonry wall, and the movable inner sash 113 of the inner leaf 109 arranged therein. The sash 113 can accommodate, for example, an opaque filling plate here. It can be sufficient to design the inner leaf 109 in a simple manner. The inner leaf 109 can preferably be designed as a rotating leaf or turn-tilt leaf.

[0103] At least one plane having a seal (not shown here) is located between the sash 111 and the frame 110. Frame profiles, in particular in thermally-insulated construction, are preferably used for the frames 110, 111. The base material of the frame 111, 110 can be a metal such as steel or aluminum or also wood or plastic. Moreover, mixed forms are usable, in which the inner frame and the outer frame consist of various materials. Multiple different materials such as wood or plastic or the like are also usable in each frame.

[0104] As shown in FIG. 13, instead of two fixed frames 110, 112 for the window element 100a according to the invention, a single fixed frame 114, which is arranged between the two planes inner leaf and outer leaf and is continuous between these planes, having double stop can also be used for the inner leaf and the outer leaf.

[0105] Preferably, one, multiple, or all of the fixed frames and sashes are embodied in thermally-insulated embodiment. This means that if aluminum is preferably used from the inside to the outside on the respective frame, a multilayered structure having one or multiple aluminum profiles and at least one insulating profile plane arranged in between made of insulating profilesin particular made of plasticis implemented.

[0106] A type of masonry wall is illustrated by dashed lines in each of FIGS. 12 and 13 below the fixed frame or frames 110, 112, wherein it delimits a wall opening or a building opening. However, another faade element can also adjoin here in one direction or all around the frame, for example, a further element of a faade, which is designed as a mullion/post construction or a further element of an element faade, the elements of which are assembled preinstalled at the construction site like a chessboard in rows and columns, wherein these further elements preferably do not comprise a device 103.

[0107] One embodiment of the window element 100a in preferred construction having an intermediate space 108 is illustrated in each of FIGS. 14 to 17. In each case the intermediate space 108 is shown having the outer leaf 102 toward the building outside and the inner leaf 109 toward the building inside. The illustrations in respective FIGS. 14 to 17 differ due to the respective opening kinematics.

[0108] FIGS. 14 and 16 or 15 and 17 each show in a three-dimensional view or in a side view, respectively, the preferred arrangement toward the building outside having an outer leaf 102 movable around a horizontal axis of rotation and toward the building inside having an inner leaf 109 movable around a vertical axis of rotation. However, other opening kinematics with the window element 100a and/or the leaves 102, 109 are also possible. These include, for example, sliding leaves, pivoting leaves, or folding leaves. The leaves 102, 109 can also be embodied in multiple parts.

[0109] The preferred window element 100a illustrated in FIGS. 14 to 17 suggests a so-called casement window in its design. The casement window or also double window systems consist of two window elements arranged at a distance to one another. Further advantages for the window element 100a result due to the embodiment as a casement window.

[0110] These include that the window element 100a can advantageously additionally be used as a ventilation element. The function as a receiving and sending station for letter and parcel shipments is not restricted in this way. The window element 100a according to the invention can accordingly additionally be equipped with ventilation channels, heat exchanger units, air filters, and sound-insulating elements. The technical utility of such a window element 100 is advantageously increased in this way.

[0111] A further preferred structure of the window element 100 according to the invention is described hereafter on the basis of FIG. 18 and FIG. 19.

[0112] The intermediate space 108 is preferably formed by a continuous fixed frame 114 having double stop for the inner leaf 109 and the outer leaf 102.

[0113] The outer leaf 102 preferably rotates outward here around a horizontal axis in an opening movement. The inner leaf 109 preferably rotates around a vertical axis in an opening movement. This is preferable but not required.

[0114] The device 103 is arranged on the inner side of the outer leaf 102 and preferably comprises the housing 107. The housing 107 preferably comprises a flap K (see also FIG. 8) or door for removing or depositing the transport material. The telescoping thrust device 105 is arranged, on the one hand, on the outer leaf 102 or on the housing 107 and, on the other hand, on the landing region 104. The landing region 104 can be moved by the thrust device 105 into the housing 107. The landing region 104 can be designed as a simple surface, as a funnel-type surface, or as a pickup element 106.

[0115] The window element 100a is illustrated viewed in a front view from a room of the building in FIG. 19. The inner leaf 109 is open so that it is possible to look into the intermediate space 108 of the window element 100. The landing region 104 is retracted into the housing 107 and the outer leaf 102 is closed. To open the pickup element 106, the flap K can be opened, in order to remove a transport material or place it in the pickup element 106. The window element 100a illustrated here has a particularly large outreach, i.e., the landing region 104 is accordingly arranged far from the building 1 when the outer leaf 102 is open. Standard windows according to DIN EN 14351-1:2006-07, appendix E (window up to 2.3 m.sup.2: 1.231.48 m, window >2.3 m.sup.2: 1.482.18 m) having a sash height of 1.48 m accordingly preferably move the landing region 104 more than 1.5 m away from the building wall.

[0116] The window element 100a according to the invention can be arranged as a separate whole or as a partial segment of a larger element. One advantageous embodiment in this case is if the window element 100a is formed as a side part to a window 115 having an insulating glass pane. This is shown in FIG. 20.

[0117] However, the faade element 100a can also be inserted into the balustrade of a faade 2. It is furthermore possible to use element 100a as a side part of a door. The element 100a of a window, door, or faade according to the invention close to the groundi.e., for example, installed in the ground floorcan theoretically also be reached by air vehicles such as drones orwhere this is not permittedserved by autonomously driving transport vehicles or such land vehicles.
