Description

Outdoor seat for arranging in or on a building opening of a building structure connecting an interior space with an exterior space

The invention relates to a free seat for arranging in or on a building opening of a building structure that connects an interior space with an exterior space.

The possibility of visiting an area of an apartment that is free from the environment is a criterion in an apartment that positively influences the quality of living. For this purpose, apartments are partially equipped with balconies or terraces. A not inconsiderable proportion of the existing living space is not equipped with balconies or terraces and consequently shows a deficit with regard to this usually highly valued living space criterion. In the course of the densification of living space, the provision of balconies and in particular terraces is only possible to a limited extent in new buildings. A not inconsiderable proportion of the buildings in the existing stock also have no balconies or terraces.

The invention is based on the object of increasing the quality of living in an apartment with regard to a simple and quick as well as inexpensive and variable measure.

The object is achieved by a free seat for arranging in or on a building opening of a building structure connecting an interior space with an exterior space according to claim 1 . The dependent claims relate to possible embodiments of the free seat as well as a building structure and a method relating to the free seat described herein.

The invention relates to a free seat for arranging in or on a building opening of a building structure connecting an interior space with an exterior space, comprising a kinematic device comprising a plurality of components that are movably connected to one another and which can be moved into a use position and into a non-use position. The outdoor seat is characterized in that the kinematic device is set up to move at least one component when transferring from the non-use position into the use position into a position located in an exterior space below the building opening. Due to the fact that the kinematic device and in particular the lounge created by the kinematic device extends at least partially below the position of the building opening for a person using the outdoor seat, an advantageous utilization of the area available outside can be achieved. The acceptance of the free seat by potential users is also increased by at least partially arranging the usable space provided or enabled by the free seat or the recreation room on a similar level to the section (room) of the interior space having the building opening. The lounge created by the outdoor seating can be perceived as an extension of the interior. The kinematic device has z. B. at least two components. In other words, in the position of use, through the free seat, in particular by the kinematic device, useful volume created in the outside space at least partially extend below the lower edge of the building opening. The patio can also be called a mobile balcony.

The interior is to be understood as the cavity formed by the building structure, typically comprising one or more rooms, which is delimited from the exterior by the building structure, for example a building wall. The outdoor space can form the space outside the building. In other words, the building opening forms a connection between the exterior and the interior.

The usage position of the kinematic device forms the intended usage position and/or alignment of at least one component, in particular of all components, of the kinematic device for using the kinematic device as a free seat, such that at least one person is at least partially, in particular completely, in the building opening and/or in particular exclusively, in the outdoor space can stay and the free seat fulfills a fall protection function for this person. The at least one person can be seated and/or lying and/or standing at least in sections in the building opening and/or at least in sections in the outside space, preferably at least in sections in the usable space created by the outdoor seat in its position of use, by means of the kinematic device in the position of use or recreation room. The kinematic device can (a) fall protection for the at least one person using the outdoor seat and/or (b) an area for intended contact with the at least one person using the outdoor seat, e.g. B. form a seat. Consequently, the at least one person using the free seat is enabled by the free seat to stay safely at least partially in the area of the building opening and/or at least partially in the outside area.

The usage position is typically to be understood in such a way that the free seat fulfills its protective and/or usable space-expanding function at least in the usage position. Here, the free seat can be arranged at least partially outside the building structure or outside. The non-use position can be characterized, for example, in that the free seat has a compact size in the non-use position and/or is arranged at least predominantly, preferably entirely, in the interior of the building structure. If the free seat can be arranged completely in the interior in the non-use position, this means that the building facade is not adversely affected in terms of design or aesthetics by the free seat when the free seat is in the non-use position. This aspect can increase the acceptance of the seat for the user and/or for third parties.

The arrangement of the kinematic device in the position of use can, for example, be measured at least in sections below the building opening a distance from a include the lower edge or a lowest point of the building opening vertically downwards. In other words, a usable space extending below the lower edge of the building opening is created by the at least partially downward extension of a component of the kinematic device by the kinematic device.

It is possible that a free seat is provided for use with a building opening connecting the interior space with the exterior space of a building structure, which includes an anchoring element that can be arranged or arranged or formed in the interior space and/or in the building opening and a parapet element that is movably attached to the anchoring element , wherein in a non-use position of the free seat, the parapet element is at least partially, in particular completely, arranged in the interior. In the position of use of the free seat, the parapet element can be arranged in the exterior, with the parapet element being moved at least partially, in particular completely, through the building opening during the movement between the position of non-use and the position of use.

The building on which the free seat is used can be designed, for example, as a house, preferably as a residential building, particularly preferably as a multi-story apartment building. The building opening can be located, for example, on the first floor or on a floor further up. The building opening can be designed as a typical window opening, for example. For example, such a building opening is arranged or formed with its lower region at least 25 cm, preferably at least 40 cm, particularly preferably at least 65 cm, most preferably at least 75 cm, above the floor of the room provided with the building opening. Alternatively, it is possible for the building opening to be in the form of a floor-to-ceiling window, in which case the lower edge of the building opening can coincide with the level of the floor. Provision can be made, for example, for the kinematic device to be configured with components mounted such that they can move with respect to one another such that during an at least partial rotational movement of individual or all components of the kinematic device with respect to one another, the latter can be moved through an opening in the building. The building opening can, for example, have an opening height of at most 140 cm, preferably at most 120 cm, particularly preferably at most 80 cm. The opening height of the building opening can be understood here, for example, as the distance between the lowest point and the highest point of the building opening.

It is possible that in the position of use the kinematic device forms a usable volume arranged outside and at least in sections below the building opening for use as at least in sections a recreation room for a person using the outdoor seat. The usable volume or the lounge can, for example, be delimited or defined at least in sections by components of the kinematic device, in particular completely or in regions. This useful volume can B. such be configured and/or arranged such that it is suitable for receiving at least one foot and/or for receiving at least one leg of at least one person using the outdoor seat as intended. In other words, the possible occupancy area of the interior is expanded by the useful volume generated by the kinematic device.

In an advantageous development, it can be provided that in the position of use of the free seat, a lowest point of a component of the kinematic device arranged at least outside is at a distance from the building opening that is equal to or greater than a quarter, preferably equal to or greater than half, particularly preferably equal to or greater than is greater than two-thirds, most preferably equal to or greater than the maximum, in particular horizontal, distance of the kinematic device from a surface of the building structure facing the outside space. The distance from the deepest point of the component arranged outdoors to the nearest or to the deepest point of the building opening can relate, for example, to the vertical distance between the two points. In this case, the building opening to which the free seat is assigned or the building opening through which the kinematic device passes is considered. The maximum horizontal distance of the free seat in the position of use is to be understood as the maximum horizontal extension of the free seat mounted on a building opening. The maximum horizontal distance can run from a surface of the building structure having the building opening facing the outside space to a point of the free seat which is at a maximum distance from the surface of the building structure and projected in a horizontal plane.

It is possible for a second component to be movably connected to a first component via a first joint area and for a third component to be movably connected to the second component via a second joint area. A fourth component can preferably be movably connected, for example, to the third component via a third joint area. In a further advantageous embodiment, the fourth component can be movably connected to a fifth component via a fourth joint area. The connection of the at least two components, in particular all of the components, can in this case include a direct movable mounting of the components that are respectively adjacent to one another. For example, at least one component can preferably be connected directly or directly to a maximum of two further components. So e.g. B. the components form a kind of chain, so that the first link (component) of the chain is at least temporarily movably connected to the last link (component) of the chain via intervening links (components). This chain-like structure enables the links to be folded up or folded together into a compact form. This temporary reduction in the space occupied by the kinematic device can be advantageous for storing the free seat in the non-use position and/or for at least partially moving the kinematic device through a building opening. It is advantageous if the individual Links of the chain-like structure are at least partially limited or inhibited in their respective mobility to the adjacent links or components.

It is possible for the kinematic device, in its position of use, to enclose, at least in sections, a wall region of the building structure located below the building opening in an L-shape or U-shape. Provision can be made here for the kinematic device to have at least two components which, at least in the position of use, surround a wall region of the building structure located below the building opening in an L-shape or U-shape. The L-shaped or U-shaped handle of the wall area located below the building opening preferably extends through the kinematic device at least in sections into the exterior. The surrounded wall area of the building structure can thus be surrounded or accommodated by the space of the kinematic device defined by the free, L-shaped and/or U-shaped legs. This can prove to be advantageous, for example, if in particular the sections of the kinematic device arranged in the exterior have no contact with the building structure, in particular no contact with the surface of the building structure facing the exterior. A risk of damage to an insulation arranged on the outside of the building structure or building facade through the free seat can thus be ruled out.

It can prove to be advantageous if a first component is designed as an anchor element which connects the outdoor seating area to the building structure. The anchor element can be fastened or can be fastened to the building structure, for example in the building opening and/or in the building interior. The anchor element can be connected to the building structure, for example, via a force-fitting and/or form-fitting and/or material-to-material connection. For example, the anchor element can be fixed by means of screws received in dowels set on the wall side.

In the non-use position, the kinematic device can be arranged predominantly, in particular exclusively, in the interior. In this case, it is possible for the kinematic device to be arranged at least predominantly, in particular completely, below the building opening associated with the kinematic device in the non-use position. This makes it possible to open and close an inward opening window of the building opening even while the kinematic device is in the non-use position, since the kinematic device is arranged sufficiently low so as not to impede an opening or closing movement of the window.

It is possible that at least one further component, in particular all components, of the kinematic device is or are connected to the building structure exclusively via the anchor element. The fact that the predominant, in particular exclusive, attachment of the patio with the building structure by means of the Anchor element takes place, a high degree of freedom can be achieved with respect to the relative movements of the respective components of the kinematic device, since only the anchor element has a fixed position and orientation in relation to the building structure. The free seat can for example be designed in such a way that the anchor element represents the only or exclusive attachment of the free seat to the building structure. Alternatively, it can be provided that the free seat is in contact with the building structure exclusively via the anchor element and via at least one, in particular exclusively via one, component which contacts the building opening.

The kinematic device can, for example, (a) have a first component that is or can be fastened in the interior or in or on the building opening, with a further component of the kinematic device being movably fastened or fastened to the first component in such a way that the further component for the Reaching the usage position can be transferred or moved from the interior via the building opening and/or out of the building opening to the exterior. This allows individual components of the kinematic device to be collapsed and/or folded together and/or displaced in relation to one another in such a way that at least some of the components can pass through the building opening.

For example, at least two components may be releasably attached to one another, i. H. e.g. B. that the further component of the first component non-destructive, in particular without the use of a tool can be solved manually. Alternatively or additionally, it can be provided that at least two components, in particular all components, of the kinematic device are permanently fastened to one another. i.e. e.g. B. that these at least two movably connected components cannot be detached or separated non-destructively and/or without the aid of a tool. In this way, a manipulative or inadvertently performed action can be prevented in a simple manner, which in principle can cause an increased risk for a person using the outdoor seat.

In a further embodiment, it can be provided that a parapet element is or can be movably connected directly or indirectly to the anchor element; in particular, the parapet element extends into the exterior space in the usage position of the kinematic device in such a way that the parapet element with its main plane of extension is in line with the main plane of extension of the building structure or A building facade encloses an angle of at most 85°, preferably at most 80°, particularly preferably at most 75°, most preferably at most 70°. Due to the specified opening angle between the main extension plane of the parapet element and the main extension plane of the building structure and/or to a vertical element of the kinematic device running parallel to a building facade of the building structure in the usage position of the kinematic device, the parapet element can create a usable volume be generated, which serves to accommodate at least a portion of at least one person using the outdoor seat. The main extension level of the building structure can form a building facade, for example. In the case of a planar body, the main extension plane of the parapet element can be defined by the plane running through the body. Unless the parapet element as a purely flat body, z. B. is formed as an at least partially bent or kinked body, the main plane of extent is specified by the predominant spatial extent of the parapet element or by a plane inscribed in this body. A minimum angle which the main extension plane of the parapet element encloses with the main extension plane of the building structure can, for example, be at least 5°, preferably at least 10°, particularly preferably at least 15°, most preferably at least 20°.

It is possible for a horizontal element to be movably connected or connectable, in particular directly, to the anchor element and/or movably to the parapet element, with the horizontal element having an angle of less than or equal to 45°, preferably less than or equal to 35°, in the position of use. particularly preferably less than or equal to 20°, most preferably less than or equal to 10°, with a horizontal line, in particular a building base area. In a particularly advantageous embodiment, the horizontal element is aligned essentially parallel to a horizontal line in the position of use. For example, the horizontal element can serve as a seating area or seat surface for at least one person using the free seat in the position of use as intended. The horizontal line can typically be determined using a spirit level or a comparable measuring device, with the recorded inclination corresponding to an inclination of 0°. In other words, the horizontal line describes a straight line running at right angles to the vertical direction. The kinematic device can be designed, for example, such that the horizontal element is arranged in sections in the building opening when the free seat is in the position of use; the horizontal element preferably extends from the interior through the building opening to the exterior. In other words, the horizontal element can serve as, in particular exclusively, a supporting element for fastening the components of the kinematics device which are arranged outside in the position of use with components of the kinematics device which are fastened to the building structure. In this way, the horizontal element can be designed so rigidly and firmly that it can carry out the sole carrying function for components arranged outside, at least in the position of use of the free seat, without significant plastic or elastic deformation.

In an advantageous development, it can be provided that a horizontal element is or can be movably connected, in particular directly, to the anchor element and/or to the parapet element, with a main plane of extension of the horizontal element being at an angle in the area of the main plane of extension of the parapet element in the position of use of the kinematic device from 45° to 160°, preferably from 70° to 150°, more preferably from 80° to 140°, most preferably from 110° to 130°. A kinematic device is thus achieved which comprises few components and at the same time can be folded up or brought together in a compact manner in the non-use position, with a safety function being provided by the free seat in the use position.

It is possible for a vertical element of the kinematic device to be or can be movably connected, in particular directly, to a horizontal element of the kinematic device and/or to a parapet element of the kinematic device, with a main extension plane of the vertical element having a main extension plane of one separating the interior from the exterior in the position of use Wall of a building structure encloses an angle of less than or equal to 45°, preferably an angle of less than or equal to 25°, particularly preferably an angle of less than or equal to 10°, most preferably an angle of less than or equal to 5°. The vertical element can, for example, be arranged or designed in such a way that it is arranged outside when the free seat is in the position of use, extending from a lower edge of the building opening into an area below the building opening. In other words, the vertical element can serve to guide or carry at least some of the components of the kinematic device, which are arranged outside in the usage position, into an area below the building opening. In an exemplary embodiment, the main extension plane of the vertical element runs parallel to a wall of the building structure that separates the interior from the exterior.

At least two components, in particular all components, of the kinematic device can be designed such that they can be moved relative to one another in rotation and/or translation via a joint area, with the components taking up more space in the use position than in the non-use position. In the non-use position, the components are preferably present in a compact state and can be transferred into a use position via at least one at least partially rotary movement of at least two components, with the kinematic device taking up a larger space in the use position. The rotational and/or translational mobility of two adjacent components in relation to each other, which is made possible via the joint area, can be, for example, (a) a rotary or pivoting movement, in particular exclusively, made possible about a rotational axis and/or (b) a, in particular exclusively, linearly guided movement along a straight line of movement and / or (c) include a superimposed rotary and linear movement. The latter can take place, for example, via a rotary and sliding joint, for example a longitudinal hole guide or a rod guide comprising a counter-element rotatably mounted on a rod element. It is possible for the counter-element that movably connects two structural elements that are adjacent to one another to allow a movement in at least one translational and/or at least one rotational degree of freedom. It is possible for the free seat to comprise a connecting element, for example, which is or can be movably connected, in particular directly, to the anchor element and a horizontal element, with the connecting element or the at least one joint region being designed in such a way that the horizontal element is connected at least during a first phase of movement performs a, in particular exclusive, rotational movement and, during at least a second phase of movement, a, in particular exclusive, linear movement relative to the anchor element. The connection between the anchor element and the connecting element can preferably be designed in such a way that, in particular exclusively, a linear movement of the connecting element relative to the anchor element can be carried out. In this case, for example, the connection of the connecting element to the horizontal element can additionally be designed in such a way that the horizontal element executes or can execute a rotational movement relative to the connecting element, in particular exclusively.

At least two components, in particular all components, of the kinematic device can be movable relative to one another, for example, with the mobility of at least one component relative to another, in particular adjacent component being at least temporarily blocked or blockable and/or limited or limited to a predefined degree of movement. In other words, a relative movement of at least two components can be forcibly guided and/or limited at least during a portion of the movement of the kinematic device between the position of use and the position of non-use. Here, for example, a stop area can be provided on any first component, which, through contact with a counter-contact area of a further component movably mounted on the first component, enables an end position limitation for a predefined alignment and/or position of the first and the further component relative to one another. By providing forced guidance and/or limitations on the mobility of the components relative to one another, the handling of the kinematic device can be simplified for the operator and undesired movements can be prevented. For example, a horizontal element of the kinematic device that is directly rotatably connected to a vertical element can be limited in the permitted or enabled angular position. For example, an angle between the horizontal element and the vertical element that results in the course of an “unfolding” can be limited to a maximum of 110°, preferably 100°, particularly preferably 90°. Alternatively or additionally, it can be provided that an angular position limitation for the rotational movement of a horizontal element relative to an anchor element, in particular to a connecting element connecting the horizontal element to the anchor element, is effective in such a way that during the displacement of the kinematic device from the non-use position to the use position, a the opening angle resulting from this can reach a maximum angular value of 300°, preferably 285°, particularly preferably 270°. The angular position of the horizontal element with the anchor element or with the connecting element in the non-use position can assume an angular value of less than 15°, preferably less than 10°, particularly preferably less than 5°, most preferably essentially 0°. It is possible that, at least in the position of use (a), a rotational mobility of a horizontal element of the kinematic device relative to an anchor element of the kinematic device is limited or can be limited in a predefined manner; a rotation between the horizontal element exceeding 300°, particularly preferably exceeding 270°, is preferred and the anchor element and/or (b) mobility, in particular rotational mobility, of a horizontal element of the kinematic device relative to a vertical element of the kinematic device is limited or can be limited in a predefined manner, preferably the mobility of the vertical element is restricted to a position covered or covered by the horizontal element in the position of use The vertical element is particularly preferably limited in its movability relative to the horizontal element in such a way that the vertical element is not more than 30% covered by the horizontal element in the position of use area can be moved and/or (c) a rotational mobility of a horizontal element of the kinematic device relative to a linear path of movement of the horizontal element is limited or can be limited on an anchor element of the kinematic device in such a way that a main extension plane of the horizontal element encloses at least a predefined angle with the linear path of movement, preferably the main extension plane of the horizontal element encloses an angle of at least 25°, particularly preferably at least 80°, most preferably at least 90° with the linear movement path, and/or (d) limits a rotational mobility of a vertical element of the kinematic device relative to a parapet element of the kinematic device or can be limited, so that the vertical element encloses a predefined angle with the main extension plane of the parapet element. For example, unfolding of the parapet element with the vertical element can be limited by means of a stop in such a way that the rotary movement is not permitted beyond the predefined maximum angle. In this context z. B. the maximum angle predetermined by the limitation is 45°, preferably 40°, particularly preferably 30°, most preferably 25°. The limitations on the mobility of the respective components relative to one another allow, for example, comfortable handling of the kinematic device and/or prevent dangerous movements (e.g. injuries due to crushing) and/or undesired contacts or evasive movements of components in or on the building structure.

In addition to a free seat, the invention also relates to a building structure comprising a free seat described herein and/or a method for at least temporarily providing a free seat on a building structure, wherein a free seat according to one of the preceding claims is transferred between a use position and a non-use position.

The free seat can B. be designed as a retrofit device, so that, for example, existing apartments can be retrofitted with little effort by installing the free seat with a possibility of a safe stay outdoors. Consequently, for example, the anchor element can be designed in such a way that it can be mounted on an existing building structure in a simple and/or secure manner. Alternatively, he can Outdoor seating can be installed as a device planned in a new building or integrated into a building structure. Here, the anchor element z. B. be integrated into the building structure at least in sections during the construction of this.

In an advantageous embodiment, it can be provided that at least one component of the kinematic device, preferably the majority of the components of the kinematic device, are designed as identical parts for different shoring sets or shoring variants of the free seat. So e.g. B. the anchor element and/or the connecting element are available in at least two variants, with a first variant enabling the free seat to be fitted to an existing building structure in the sense of a retrofit device, and at least one further variant allowing the free seat to be fitted or integrated into an at least partially newly constructed building Area of a building structure allows. The other components of the kinematic device (e.g. horizontal element, vertical element and/or parapet element) can be used at least in part as identical parts for the shoring sets or shoring variants. The anchor element and/or the connecting element of the kinematic device can, for example, have features that are optimized for the respective application or for the respective shoring variant.

All advantages, details, designs and/or features of the free seat according to the invention can be transferred or applied to the building structure and to the method.

Figure 1 shows a patio 1 for arranging in or on a building opening 4 of a building structure 5 connecting an interior space 2 to an exterior space 3. This patio space 1 has one, several movably connected components 6, 6', 6", 6'", 6 "" Comprehensive kinematic device 7, which can be converted into a position of use 8 and a position of non-use 9. In the state shown in Figure 1, the free seat 1 is in the position of use 8, d. H. At least a part of the free seat 1 extends into the open air or into the outside space 3 in the position of use 8. The kinematic device 7 is set up here, at least one component 6, 6′, 6″, 6″″, 6″″ during a transfer to move from the non-use position 9 to the use position 8 in a position located in the exterior 3 below the opening 4 in the building. As can be seen particularly well in Figures 1 and 4, the components 6'' and 6'' extend almost completely or predominantly into an area below the building opening 4.

In the position of use 8, the kinematic device 7 forms a usable volume 10 arranged in the exterior 3 and at least in sections below the building opening 4 for use as at least a section of recreation space for a person (not shown) using the outdoor seat 1. It can be seen that when a person using the outdoor seat 1 uses the horizontal element 20 or the component 6″ as a seat and extends their feet into the exterior space 3, the feet can be aligned or arranged in the useful volume 10, for example. Consequently, the free seat can be used to safely expand the living space or to enable a balcony-like feeling of use. In this way, for example, smokers can go to the exterior 3 to smoke, so that any smoke deposits or possible odor nuisance in the interior 2 can be reduced or prevented. In this way, the outdoor seat 1 described herein can make a contribution to health promotion, since a person staying in the interior 2 is not impaired or bothered to a lesser extent by any smoking activities of a person using the outdoor seat.

In the position of use 8 of the free seat 1, for example, a lowest point 11 of a component 6, 6', 6", 6"', 6"" of the kinematic device 7 arranged at least in the exterior space 3 can have a distance 12 from the building opening 4 that is the same or greater a quarter, preferably equal to or greater than half, particularly preferably equal to or greater than two thirds, most preferably equal to or greater than the maximum, in particular horizontal distance 13 of the kinematic device 7 to a surface 14 of the building structure 5 facing the exterior space 3 . The lower edge of the building opening 4, in particular for determining the distance 12, can form the lower edge of the wall panel of the building structure 5, see Figure 4. The lower edge of the building opening 4 can also be regarded as the lower edge of a window frame installed in the building opening 4 . In general, the lower edge of the building opening 4 can be regarded as the area or the opening section in the building structure, which is necessary for the passage of parts of the building elements 6, 6', 6", 6'", 6"" or for the partial passage of the free seat is available.

A second component 6 ′ can be movably connected to a first component 6 , for example via a first joint area 15 . A third component 6" can be movably connected to the second component 6', for example via a second joint area 15'; a fourth component 6'' is preferably movably connected to the third component 6" via a third joint area 15". The fourth component 6″ can be movably connected to a fifth component e″″ via a fourth joint area 15″″. According to the embodiment shown in FIGS. B. along a rod-shaped portion of the first component 6 is mounted linearly displaceable. It can be seen from Figures 5 and 6 that the second component 6' (connecting element 25) relative to the first component 6 (anchor element 17) is moved upwards from the non-use position 9 shown in Figure 5 to a higher position. The other components 6", 6'", 6"" remain unmoved in relation to one another in this movement phase. In FIGS. 6 to 12, the components 6′, 6″, 6″″, 6″″ are shifted into the position of use 8 predominantly in the manner of an unwinding opening movement. In the position of use 8, the kinematic device 7 can, for example, at least partially encompass a wall region 16 of the building structure 5 located below the building opening 4 in an L-shape or U-shape, see Figure 4.

As can be seen in particular from FIG. 3, the connecting element 25 has two bearing bodies which are each mounted in a longitudinally movable manner on a rod-shaped section of the anchor element 17 . The two bearing bodies of the connecting element are connected to a connecting strut on which the horizontal element 20 is rotatably mounted.

As can be seen from Figures 5 to 12, it can be provided that in a first movement phase during the displacement of the components 6, 6', 6", 6'", 6"" from the non-use position 9 to the use position 8 at least one Group of components 6, 6', 6", 6'", 6"" initially do not move relative to one another; See components 6', 6", 6'", 6"" which in the movement phase of Figures 5 to 8 together perform a linear displacement along the linear movement path 23 (transition from Figure 5 to Figure 6) and then a rotary movement around the joint area 15' run (transition figures 6 to 8). in transition 8 to 12, the components 6′, 6″, 6′″, 6″″ are pivoted open.

In the non-use position 9, the horizontal element 20 with the anchor element 17 and/or the horizontal element 20 with the vertical element 19 and/or the horizontal element 20 with the main extension plane 26 of the parapet element 18 and/or the anchor element 17 with the vertical element 19 and/or the anchor element 17 enclose an angle of less than or equal to 15° with the main extension plane 26 of the parapet element 18 and/or the vertical element 19 with the main extension plane 26 of the parapet element 18, preferably enclose an angle less than or equal to 10°, particularly preferably enclose an angle less than or equal to 5°, most preferably be aligned substantially parallel to each other.

A first component 6 can be designed, for example, as an anchor element 17, which connects the free seat 1 or the other components 6', 6", 6", 6"" of the kinematic device to the building structure 5. The anchor element 17 is preferably fastened or can be fastened to the building structure 5 in the building opening 4 and/or in the interior space 2 . As can be seen in particular from Figure 4, the anchor element 17 comprises two rod-shaped base bodies, with connecting bodies being provided at the ends of the respective rod-shaped base bodies in order to connect the anchor element 17 to the building structure 5 in a non-positive and/or material and/or positive manner fortified. In a further development, it can be provided, for example, that at least one further component 6′, 6″, 6″”, 6″″, in particular all components 6′, 6″, 6′″, 6″″, of the kinematic device 7 exclusively via the anchor element 17 is connected or can be connected to the building structure 5 . It can be seen from the illustrated embodiment that all components 6', 6", 6", 6"" are attached to the building structure 5 exclusively via the first component 6. All components 6, 6', 6", 6", 6"" thus form a chain of components 6, 6', 6", 6"", 6"", which can be moved relative to one another to a limited extent.

A parapet element 18 can, for example, be movably connected or connectable to the anchor element 17 directly or indirectly. For example, in the usage position 8 of the kinematic device 7, the parapet element 18 extends in such a way that the parapet element 18 with its main plane of extension 26 forms an angle a of at most 85°, preferably of a maximum of 80°, particularly preferably of a maximum of 75°, with the main plane of extension of the building structure 5 preferably of a maximum of 70°. Alternatively, the angle a can be defined with the stated value ranges between the main extension plane (28) of the parapet element 18 (a) with the main extension plane of the anchor element 17 and/or (b) with a linear movement path of a second component 6' on the anchor element 17. The parapet element 18 can, for example, form the component 6'''' lying opposite the anchor element 17 in a chain of components 6, 6', 6'', 6'''', 6''''. The parapet element 18 can, for example, fulfill a parapet function and thereby at least partially surround a useful volume 10 located in the exterior 3 in such a way that the risk of falling is minimized. The parapet element 18 can or be designed in several pieces. The parapet element 18 can be designed, at least in sections, in the manner of a lattice or railing and/or at least in sections as an uninterrupted or solid wall panel.

As shown in the embodiment shown in the figures, the parapet element 18 can be designed, for example, as a flat body, with the parapet element having at least one kink and/or bending area 24 . The buckling and/or bending area 24 can include, for example, at least in sections, in particular exclusively, a straight line as a buckling and/or bending line. In a preferred embodiment, at least one straight buckling and/or bending line of the buckling and/or bending region 24 runs parallel to a pivot axis of the parapet element 18 to an adjacent component 6'' of the kinematic device 7, in particular one that is rotatably connected directly to the parapet element 18 The buckling and/or bending area 24 of the parapet element 18 makes it possible in a simple manner for the free seat 18 to form a compact shape in the non-use position 9 . For example, an inner angle of two surface areas connected via the buckling and/or bending area can be an angle of 90° to 180°, preferably 120° to 180°, particularly preferably 140° to 175°, most preferably 150° to 170°, lock in.

The buckling and/or bending area 24 of the component 6″″, in particular of the parapet element 18, can, for example, be temporarily adjustable and lockable in terms of its angle. Alternatively or additionally, the structural element 6″″, in particular the parapet element 18 , can be designed in several parts, with a first partial parapet element 30 being aligned horizontally in the usage position 8 of the outdoor seat 1 . Another parapet part element 30' can fulfill the actual parapet function. The at least two partial parapet elements 30, 30' forming the parapet element 18 in one variant are shown in FIG. 4 as a dash-dot-dot line, with the second partial parapet element 30' being shown broken.

Provision can be made, for example, for at least two structural elements 6, 6′, 6″, 6″, 6″″ to have a connection via a tension element 31 that can be subjected to tensile stress at least in the usage position 8 of the free seat 1 . In the illustrated embodiment, the tension element 31 is arranged between the parapet element 18 and the vertical element 19 and transmits a tensile force acting on the parapet element 18 to the vertical element 19. The tension element 31 can be constructed in several parts, in particular foldable. In particular, a foldable pull element 31 can assume a stretched and/or overstretched shape in the position of use 8 . The tension element 31 preferably forms a knee lift with the parapet element 18 and the vertical element 19, which achieves a locking effect, for example by overstretching the knee lever.

A horizontal element 20 or a component 6 "can, for example, be moved with the Anchor element 17 and/or be connected or connectable to the parapet element 18, with the horizontal element 20 in the position of use 8 having an angle of less than or equal to 45°, preferably less than or equal to 35°, particularly preferably less than or equal to 20°, most preferably of less than or equal to 10°, with a horizontal line 21 includes. In the illustrated embodiment, the horizontal element 20 , in particular forming a seat surface for one person, is aligned parallel to the horizontal line 21 in the position of use 8 .

A horizontal element 20 or a structural element 6" can, for example, be or can be movably connected, in particular directly, to the anchor element 17 and/or to the parapet element 18, with a main extension plane of the horizontal element 20 being one with the main extension plane 26 of the parapet element 18 in the usage position 8 Angle b in the range from 45° to 160°, preferably from 70° to 150°, particularly preferably from 80° to 140°, most preferably from 110° to 130°. If the main extension plane 26 of the parapet element 18 has an angle of greater than or equal to 90° with respect to the horizontal element 20, a foot area (useful volume 10) provided in the position of use 8 of the free seat 1 can thus have an area that increases upwards.

A vertical element 19 or the structural element 6"" of the kinematic device 7 can, for example, be or can be movably connected, in particular directly, to a horizontal element 20 of the kinematic device 7 and/or to a parapet element 18 of the kinematic device 7, with a main extension plane of the Vertical element 19 with a main extension plane of a wall 21 of a building structure 5 separating the interior 2 from the exterior 3 or the surface 14 of this wall 21 forms an angle of less than or equal to 45°, preferably an angle of less than or equal to 25°, particularly preferably an angle of less than or equal to 10°, most preferably an angle of less than or equal to 5°.

At least two components 6, 6', 6", 6'", 6"", in particular all components 6, 6', 6", 6'", 6"", of the kinematic device 7 can be connected, for example, via a joint area 15, 15' , 15”, 15″” can be moved relative to one another in rotation and/or translation, with the components 6, 6′, 6″, 6″”, 6″ taking up more space in the use position 8 than in the non-use position 9. It is It can be seen that the circumscribed volume of the components 6, 6′, 6″, 6′″, 6″″ is compact in FIG. 5 and expansive in FIG.

At least two components 6, 6′, 6″, 6″″, 6″″ of the kinematic device 7, in particular all components 6, 6′, 6″, 6′″, 6″″ of the kinematic device 7 can be designed to be movable relative to one another, for example be, the mobility of at least one component 6, 6', 6", 6'", 6"" to a further component e, 6', 6", 6'", 6"", in particular the mobility of all components 6, 6′, 6″, 6′″, 6″″ to each other, at least temporarily blocked or can be blocked and/or is limited or can be limited in a predefined degree of movement. It can prove to be advantageous if at least the mobility of the components 6, 6', 6", 6'", 6"", at least in the position of use, is predominantly and/or completely blocked or is lockable.

In the position of use 8 - see Figure 12 - it can be provided that a rotational mobility of a horizontal element 20 of the kinematic device 7 relative to an anchor element 17 of the kinematic device 7 is limited or can be limited in a predefined manner via at least one joint region 15, 15'. For example, such a limitation can prevent a rotation between the horizontal element 20 and the anchor element 17 that exceeds 300°, particularly preferably a rotation that exceeds 270°. A comparison of FIGS. 6 to 12 shows that the horizontal element 20 performs an, in particular continuous, rotary movement of a total of 270° at the joint area 15′ as the fulcrum between its displacement from the non-use position 9 to the use position 8 . It can prove advantageous if further over-rotation of the end position provided for the position of use 8 or predefined alignment of the horizontal element 20 with respect to the anchor element 17 is limited by corresponding stops, in the present case after a rotary movement of 270° has been reached.

A mobility, in particular a rotational mobility, of a horizontal element 20 of the kinematic device 7 relative to a vertical element 19 of the kinematic device 7 can, for example, be predefined or limited in at least one direction of rotation, in particular in two directions of rotation. The mobility of the vertical element 19 is preferably limited to a region 22 covered by the horizontal element 20 in the position of use 8 . It is thus possible for the vertical element 19 to be limited in its mobility relative to the horizontal element 20 by the limitation in such a way that the vertical element 19 is no more than 30%, in particular no more than 10%, particularly preferably not at all, in the The area 22 covered by the horizontal element 20 in the position of use 8 can be moved. In the illustrated embodiment, the limitation effective between horizontal element 20 and vertical element 19 is designed in such a way that it limits an interior angle of vertical and horizontal element 19, 20 pointing toward surface 14 to at least 90°. Provision can also be made for a limitation to be effective for an angular range, thereby only releasing a predefined angular range for a movement. For example, a predefined angle value is specified by the limitation. Thus, at least in the position of use 8, the limitation can have an angular value, e.g. B. exactly 90 °, so that both contact of the kinematic device 7 with the facade of the building structure 5 and a swaying movement during use of the free seat can be prevented.

Furthermore, it can be provided, for example, that a rotational mobility of a horizontal element 20 of the kinematic device 7 relative to a linear movement path 23 of the horizontal element 20 relative to an anchor element 17 of the kinematic device 7 is limited or can be limited in such a way that a main extension plane of the horizontal element 20 encloses at least one predefined angle d with the linear movement path 23 . The main extension plane of the horizontal element 20 preferably encloses an angle d of at least 25° with the linear movement path 23, particularly preferably at least 80°, most preferably at least 90°.

A rotational mobility of a vertical element 19 of the kinematic device 7 relative to a parapet element 18 of the kinematic device 7 can be limited or can be limited, for example, in such a way that the vertical element 19 encloses a predefined angle γ with the main extension plane of the parapet element 18 .

As can be seen in FIGS. 1 and 4, it can be provided that the kinematic device 7 includes a usable space limitation in addition to the components 6, 6′, 6″, 6″, 6″″. The usable space limitation can e.g. B. be designed as a limp body, which can be brought into a defined form and function by bracing or by bracing at least in the position of use 8 of the free seat 1. This limitation of usable space can e.g. B. as a net body 27, 27' laterally limit the useful volume defined by the components 6, 6', 6", 6"", 6"" and form fall protection. In other words, the usable space limitation can perform another component (in addition to parts of the components 6, 6', 6", 6'", 6") of the parapet function. If an at least partially, in particular completely, limp body (e.g. net body 27, 27') is used to delimit the usable space, its bracing can be e.g. B. containment means 28, 28'. These restraining means 28, 28' can, for example, be directly anchored to the building structure 5 and/or directly anchored to the kinematic device 7. In the illustrated embodiment, the restraining means 28, 28' are designed in the form of rods and are attached directly to the kinematic device 7. In this embodiment, the restraining means 28, 28' are attached indirectly to the building structure 5 via at least one of the structural elements 6, 6', 6", 6'", 6"". The restraining means 28, 28' are preferably arranged or designed in such a way that they form the smallest possible gap, in particular no gap 29, between the restraining means 28, 28' and the building opening 4 in the usage position 8 of the outdoor seat 1. It can be provided that at least one restraining means 28, 28' is designed to be adaptable in order to keep any gap 29 small or to close it completely by appropriate adjustment and locking of the restraining means 28, 28'.

An alternative embodiment is shown in FIGS. 14 and 15, in which a usable space delimitation is designed as a structure which completely closes off the usable space in the position of use 8 of the free seat 1 towards the outside. Here, for example, the delimitation means 32 can have, in particular, a net-like means (net body 27, 27'), which is arranged outside the building structure 5 in such a way that the usable space of the open-air seat 1 outside the building structure 5 is completely enclosed or a space in the usable space of the Freisitz located person can not fall out of this. In other words, the delimitation means 32 completely delimits the usable space outside of the building structure 5, with the exception of an access opening which the usable space of the Freisitz 1 connects via the building opening 4 to the interior 2 or makes it accessible to a person located in the interior 2 of the building structure 5 .

The delimiting means 32 can be designed, for example, as a flexible means. The delimiting means 32 can be configured, for example, at least in sections, in particular completely, in a net-like manner or from a transparent material.

According to the embodiment shown in Figures 14 and 15, the delimiting means 32 can comprise two lateral delimiting sections 33, 34 and an upper delimiting section 35, so that the delimiting sections 33, 34, 35 and the parapet element 18 and the vertical element 19, in particular additionally with at least one section of the horizontal element 20 delimits the usable space or the usable volume 10 of the free seat 1 in its position of use 8 to the space facing outside of the building structure 5 .

The at least one delimiting section 33, 34, 35 can be fastened or fastened, in particular detachably, to at least one restraining means 28, 28'. The at least one restraining means 28, 28' can, for example, be designed to be longitudinally variable. It is thus possible for the at least one restraining means 28, 28' to be designed as a rod element that can be plugged together and/or as a telescoping body. The restraining means 28, 28' serves to anchor the delimiting means 32, in particular at least one delimiting section 33, 34, 35.

In an optional embodiment, the at least one restraining means 28, 28' is designed or arranged in such a way that it comes into contact with a facing contact section 36 of the building structure 5 at least in the position of use 8, in particular exclusively in the position of use 8, of the outdoor seat 1. In this case, the contact section 36 can be supported, for example, on a window frame of the opening 4 in the building. Optionally, the contact section 36 can be located in an upper half of the building opening 4, preferably in an upper third of the building opening 4, particularly preferably in an upper quarter of the building opening 4, most preferably at an upper end (e.g. the upper boundary of the building opening). lying end be arranged or formed. Due to the fact that the contact section 36 is arranged or designed in such a way, when the contact section 36 is in contact with the retaining means 28, 28', the latter can be retained in a form-fitting manner against a tensile force acting outside of the building opening 4. In other words, the delimitation means 32 is supported via the restraining means 28, 28' on a support area located in the interior space 2 of the building structure 5.

Furthermore, the invention can include a building structure 5 comprising a free seat 1 described herein and/or a method for temporarily providing a free seat 1 described herein on a building structure 5, wherein the free seat 1 can be transferred between a position of use 8 and a position of non-use 9.
