Description

The invention relates to an interior window sill system for placement in a building opening for a window. Internal window sill systems can generally be provided for completely lining the inner peripheral side of the building opening, i.e. its frame or reveal. The inner peripheral sides of a building opening for a window can generally be divided into (with respect to a view from inside the building through the window opening to the outside) a right reveal side, a left reveal side, a vertically upper lintel side and a vertically lower sill side.

Various conventional interior window sill systems are known. In many cases, the inner window sill is permanently installed in the building wall in the area of the parapet and, if necessary, other inner peripheral sides. The inner window sill is then materially connected to the building wall, the window or both and cannot be separated from it without destroying it. With a comprehensive interior window sill system, installation is complex. Due to a permanently installed interior window sill system, the inspection of window connections and roller shutter boxes integrated into the building wall is very difficult.

Alternatively, some interior window sill systems are designed as furniture that is attached separately from and placed in front of the window. The adaptation to the room and the special window is complex. If the piece of furniture is attached to the building wall, for example at an angle, the building opening surrounding the window becomes very deep. With a fixed installation, the inspection of window connections and roller shutter boxes is made more difficult.

Furthermore, some conventional interior window sill systems are connected to the window itself. However, it has been shown that with such interior window sill systems, the interlocking of sill and window can lead to problems in the building's exterior facade. For warranty reasons, such interior window sill systems are assigned to the window, which is why window manufacturers and installers limit the selection to specific system components. This has a limiting effect on the selection of all windows and window sill systems in a building, which is often not desired. The assembly of such systems is also complicated.

It is the object of the invention to overcome the disadvantages of the prior art, in particular to provide an interior window sill system that can be easily adapted to different aesthetic ideas, that is easy to assemble and/or disassemble, and/or that is statically separate from the window frame or the Building wall can be mounted. The object of the independent claims solves this problem.

Accordingly, an interior sill system for placement in a building opening for a window is provided. Although the inner window sill system is preferably provided for attachment in the area of a window in an outer wall of a building, the person skilled in the art understands that the inner window sill system can optionally be used in the area of windows in building inner walls, for example hatches between a kitchen and a dining room. It is even conceivable to mount the interior window sill system according to the invention in a preferably rectangular wall niche.

The interior window sill system according to the invention comprises at least one anchoring structure for fastening to an inner peripheral side of the building opening or for fastening to a window frame of the window. In the case of an essentially rectangular building opening, the upper inner peripheral side in the vertical direction can be referred to as the lintel side and the lower inner peripheral side in the vertical direction can be referred to as the parapet side. The horizontally opposite inner peripheral sides of a building opening can be referred to as the right or left reveal side (in relation to a passage direction from the inside to the outside). The anchoring structure has a contact surface for surface contact with the inner peripheral side or with the window, and a mounting projection protruding from the contact surface.

Furthermore, the interior window sill system according to the invention comprises a frame unit that can be inserted into the building opening, in particular for lining the entire circumference of the inner peripheral side. The frame unit can be attached to the anchoring structure in a detachable, non-destructive manner. The frame unit has at least one mounting receptacle which is complementary to the mounting projection. The frame unit can be hung on the anchoring structure with the aid of the at least one mounting receptacle. The frame unit can be slipped over the at least one mounting projection with the at least one mounting receptacle in order to detachably fasten the frame unit in the building opening. Mounting projection and mounting seat can, for example, in the manner of a plug connection, such as a bayonet connection, one on top of the other be shape-matched. Conversely, the mounting receptacle and thus the frame unit can be pulled off the mounting projection without being destroyed in order to remove the frame unit from the building opening.

The interior window sill system according to the invention allows largely freely designable frame units to be releasably used in a building opening for a window or the like. In this way, great freedom of aesthetic design can be realized for the inner peripheral area of a building opening. Thanks to the non-destructively detachable mounting projection-mounting socket connection, the frame unit can be easily assembled and disassembled, for example in order to replace one frame unit with another frame unit, to inspect the window or a roller shutter box.

In a preferred embodiment of an interior window sill system, the frame assembly includes at least one guide for receiving the at least one mounting boss and for guiding the frame assembly between a release position and a final assembly position. In the detachable position, the frame unit can be remote from the building wall and/or the building opening. In the loose position, the frame unit can be inserted or inserted at least partially into the building opening, preferably corresponding to a distance between the anchoring structure and the inside of the building. In the final assembly position, the frame unit is preferably held stationary in the building opening by the assembly receptacle cooperating with the assembly projection. According to a simple embodiment, the mounting receptacle can be designed in the manner of a groove, the depth of which is greater than or equal to a height of the mounting projection protruding from the contact surface. Alternatively or additionally, the mounting receptacle can be designed in the manner of a groove, the width of which is greater than or equal to a width, for example a diameter, of the mounting projection. It is conceivable that the mounting receptacle does not have a boundary on both sides in the vertical direction for receiving the mounting projection, but is only formed on one side in the vertical direction in the manner of a guide rail in order to form a step, a projection or the like, which is dimensioned in relation to the set up at least one mounting projection. The frame unit preferably comprises at least one guide for guiding a translational pushing movement for inserting and/or removing the frame unit in the passage direction of the building opening. In a direction corresponding to the passage direction of the building opening, a sliding movement of the frame unit in relation to the building opening can be provided along the mounting projection that can be mounted stationarily on the building opening for mounting and/or detaching the frame unit from the anchoring structure.

According to a development of an interior window sill system, the frame unit can be positioned in a final assembly position, in particular a lowered position, in which the assembly projection is arranged in the assembly receptacle, vertically below an insertion position in the building opening, in which the assembly projection is arranged in the guide. In particular, a locking groove extending transversely to the guide, preferably in the vertical direction, forms the mounting receptacle.

According to one embodiment of an interior window sill system, the anchoring structure comprises at least one mounting plate mountable on the inner peripheral side. The mounting plate defines the contact surface. Furthermore, the contact surface comprises a mandrel protruding from the mounting plate transversely, in particular perpendicularly, to the contact surface. In a final assembly position, the mandrel can be aligned or aligned perpendicularly to the inner peripheral side. Alternatively or additionally, the mandrel can be aligned or aligned in a horizontal direction transverse to the direction of passage in a final assembly position. According to another alternative, in a final assembly position, the mandrel can be aligned or aligned in a vertical direction transverse to the passage direction. The inner window sill system can comprise two or more anchoring structures that can be mounted on different inner peripheral sides, each with at least one mounting plate and each with at least one mandrel. For example, the inner window sill system includes a first anchoring structure for mounting on the left side of the reveal and a second anchoring structure for mounting on the right side of the reveal, with its spike in the final assembly position being aligned in the horizontal direction transversely to the passage direction. In addition, the inner window sill system can have a third and, if necessary, further anchoring structures for assembly on the parapet side, with its spike in particular being aligned in the final assembly position in the vertical direction transverse to the passage direction. Preferably, the first anchoring structure, the second anchoring structure, the possible third anchoring structure and possibly further anchoring structures are identical in construction.

In another embodiment of an interior window sill system, which can be combined with the others, the anchoring structure comprises a preferably box-shaped supporting structure. The support structure has at least one support plate, in particular two, four or more support plates. In particular, the support structure can include a first support plate for attachment to the left side of the reveal, a second support plate for attachment to the right side of the reveal, a third support plate for attachment to the lintel side and/or a fourth support plate for attachment to the parapet side of the building opening. Several, in particular four, support plates of the support structure can be connected to one another according to a frame-like, rectangular or box shape. The at least one support plate has in the final assembly state in the passage direction from the building opening in the direction of the interior of the building assembly sections protruding. Protruding mounting sections realize mounting protrusions. The mounting fixture of the frame unit is shaped to match the supporting structure. The frame unit can be designed and set up to be slipped over the at least one support plate of the support structure with its at least one mounting receptacle in the passage direction in order to mount the frame unit on the building opening.

In a further embodiment, which can be combined with the others, the anchoring structure, which is preferably formed as a support structure, has at least one mounting plate that can be mounted on the inside of the circumference, in particular on the right reveal, the left reveal, the lintel and/or the parapet . In the final assembly state, the assembly plate has assembly sections which protrude in the passage direction from the building opening in the direction of the interior of the building. In a final assembly state, the mounting plate preferably extends around the entire circumference in a ring or box shape in the building opening.

According to another embodiment of the invention that can be combined with the others, the anchoring structure has at least one mounting strip that can be mounted on the window frame. The assembly band has at least one angled section which, in a final assembly state, extends partially along the circumference of the window frame. In a final assembly state, the assembly band preferably extends in an annular manner around a window opening of the window. Furthermore, the anchoring structure has a plurality of webs extending from the mounting band in the passage direction of the building opening. In relation to the building opening in the passage direction, the webs can be shorter than, as long as or longer than the thickness of the building wall. In relation to the building opening, the webs are preferably shorter than the thickness of the building wall.

In a further development of an interior window sill system with a mounting band, the supporting structure can be fastened or is fastened to the mounting band and/or the plurality of webs.

Alternatively or additionally, an embodiment of an interior window sill system includes a plurality of anchoring structures, which are preferably always of the same type. In particular, the interior window sill system comprises exactly two or exactly four, preferably identical, anchoring structures. By using the same parts, the manufacture as well as the assembly of the interior window sill system can be made particularly easy.

In a preferred embodiment of an interior window sill system according to the invention, which can be combined with the above, the frame unit is carried by the anchoring structure in a final assembly state. In the final assembly state, the frame unit is movable relative to the building opening and/or the anchoring structure. For example, the frame unit may be supported by the anchoring structure so as to be movable up and down in the vertical direction. A spring or the like can be arranged vertically below the frame unit, which pushes the frame unit upwards in the vertical direction, so that when the frame unit is subjected to a load, for example due to the weight of a person sitting on it, the frame unit yields in a resilient manner in the vertical direction.

According to a preferred development of an interior window sill system with the frame unit movably carried by the anchoring structure in the final assembly state, the frame unit is held pivotably relative to the building opening in the final assembly state. In particular, the frame unit is held so that it can pivot about a pivot axis defined by two anchoring structures, in particular mandrels. The frame unit can be hung like a swing in the building opening.

According to another development of an interior window sill system, which can be combined with the previous one, the frame unit is movably mounted in the final assembly state relative to the building opening in at least one horizontal direction corresponding to the passage direction or transverse to the passage direction of the building opening. In particular, the frame unit can be mounted in a resilient and/or motor-movable manner. Alternatively or additionally, in the final assembly state, the frame unit can be mounted so that it can move in the vertical direction relative to the building opening, in particular in a resilient and/or motor-movable manner.

In one embodiment of an interior window sill system, the frame unit comprises at least one rigid horizontal base part for covering at least one inner peripheral side, preferably the parapet side. A rigid horizontal base part is preferably designed to bear the load of at least one adult, in particular at least two, three, four or more adults (with an average weight of 80 kg) essentially without deflection. The rigid horizontal base part can be designed as a seat in the manner of a bench.

The invention also relates to an interior window sill system to be arranged in a building opening for a window, which can be designed in particular as described above. The interior window sill system includes at least one anchoring structure for attachment on an inner peripheral side of the building opening or to be fixed to a window frame of the window. Furthermore, the interior window sill system comprises a frame unit that can be inserted into the building opening, in particular for completely lining the inner peripheral side, which can be attached to the anchoring structure in a non-destructive, detachable manner. The frame unit can preferably be attached to the anchoring structure in a non-destructively detachable manner by means of an assembly projection of the anchoring structure and a corresponding assembly receptacle.

The frame unit preferably implements a viewing frame which, in particular, comprises a plurality of viewing frame sections. The multiple vision frame sections may be designed with the same or different aesthetic appearance, such as different colors and/or textures. The viewing frame sections can be detachably or non-detachably combined to form the frame unit forming a viewing frame. The frame unit forming the viewing frame is preferably structurally coherent. The viewing frame sections forming the viewing frame are preferably firmly connected to one another to form the viewing frame. Alternatively, the frame unit can have a large number of receptacles, such as push receptacles or plug-in receptacles, for detachably attaching, in particular inserting or pushing in, a number of viewing frame parts. Several, in particular all, receptacles of the frame unit preferably have the same shape. It is conceivable that the frame unit has a first group of receptacles, which are arranged along the individual inner peripheral sides, and has a second group of receptacles, which are arranged in the area of the corners between adjacent inner peripheral sides. A first group of plug-in receptacles can have an essentially flat shape. A second set of vision frame parts may have a generally angular shape. The different vision frame parts can be designed with the same or a different aesthetic appearance, for example with different colors and/or textures. The individual viewing frame parts of the interior window sill system can be assembled and detached individually, in groups, as sets or the like. Several visible frame parts of an interior window sill system can be formed in the same shape, with several visible frame parts of the interior window sill system Wahl preferably being fastened to the anchoring structure so that they can be positioned freely interchangeably with one another. The viewing frame sections or the viewing frame parts can be equipped with surface coatings, for example with a wood panel, an imitation leather panel, a genuine leather panel, a cork panel, a textile panel, a metal lining, in particular an aluminum lining, etc.

To simplify legibility, the same or similar reference symbols are used in the following description of preferred embodiments of the invention for the same or similar components.

The Figures 1-4 show a first embodiment of an interior window sill system 1 according to the invention. The interior window sill system 1 comprises an anchoring structure 3 and a frame unit 5 as essential components. The interior window sill system 1 is designed to be mountable in a building opening 101. The building opening 101 has a height in the vertical direction Z, a depth in a first horizontal direction X and a width in a second horizontal direction Y. A passage direction D extends outwards from the inside of the building through the building opening 101. A first horizontal direction X corresponds to the passage direction D A second horizontal direction Y extends transversely to the passage direction D. The building opening 101 is delimited by four inner peripheral sides 103 which are formed by the building wall 100 . With regard to the passage direction D, the inner peripheral sides 103 have a reveal side on the left and right in the second horizontal direction Y. A lintel forms the inner peripheral side 103 in the vertical direction above.

A window 201 is fastened in the building opening 101 and covers the entire surface of the building opening 101 in the vertical direction Z and the second horizontal direction Y. The window 201 shown schematically comprises a window frame 203 surrounding a window opening 205 . On the window frame 203, a window sash can be fastened, for example, so that it can pivot. The person skilled in the art understands that a building opening can alternatively be formed, for example, by a niche or a hatch without a window inserted therein (not shown in more detail).

In the figure 1 The embodiment shown of an interior window sill system 1 includes four individual anchoring structures 3. The anchoring structures 3 of the interior window sill system 1 are identical. The anchoring structures each consist of a mounting plate 32a, each with a mounting mandrel 34a.

The mounting plate 32a is formed by a square or rectangular metal sheet that has a number of recesses through which the fastening bolts, such as fastening screws, can be introduced into the building wall 100 for fastening the respective anchoring structure 3 . The mounting plate 32a can have an edge width in the range of 5 cm to 20 cm, for example. The sheet metal thickness of the mounting plate 32a is to be specified less than 10 mm, in particular less than 5 mm. The mounting plate 32a has a flat contact surface 31 which can be placed against an inner peripheral side 103 . With its contact surface 31 , the anchoring structure 3 can be brought into planar physical contact with an inner peripheral side 103 of a building opening 101 .

The assembly mandrel 34a protrudes perpendicularly from the contact surface 31. The mounting mandrel 34a implements the mounting projection 33 of the anchoring structure 3. The vertical height of the mounting mandrel 34a is significantly greater than the sheet metal thickness of the mounting plate 32a. The transverse width, here: the diameter of the mounting mandrel 34a, is significantly smaller than the width of the mounting plate 32a in the first horizontal direction X and/or significantly smaller than the height of the mounting plate 32a in the vertical direction Z when mounted on the building wall 100 for example in figure 1 is shown. The transverse width, in particular the diameter of the assembly mandrel 34a, can be in the range of 5 mm to 20 mm, for example. The height of the assembly mandrel 34a perpendicular to the contact surface 31 is preferably several centimeters, in particular the height is in the range of 5 mm to 5 cm, preferably in the range of 1 cm to 3 cm.

The first anchoring structure 3 is attached to the left soffit side 103 and the second anchoring structure 3 is attached to the right soffit side 103 such that the spikes 34a are aligned in the second horizontal direction Y and extend from the soffit side 103 into the building opening 101 . The first and the second anchoring structure 3 are arranged in the upper quarter of the building opening 101 near the lintel. The mandrels 34a of the first and second anchoring structure 3 are preferably mounted at the same point in the building opening 101 in the vertical direction Z and the first horizontal direction X. In the second horizontal direction Y, the spikes 34a of the first and second anchoring structure 3 are preferably aligned with one another in order to form a pivot axis S.

The third and the fourth anchoring structure 3 are attached to the parapet side 103 . Their spikes 34a extend in the vertical direction C from the parapet upwards into the opening 101 in the building.

In figure 1 the frame unit 5 is in a loose position. The frame unit 5 can be inserted into the building opening 101 in the direction of passage D. The frame unit 5 is made up of components that are firmly connected to one another. The lower part of the frame unit 5, which extends in the first and second horizontal directions X, Y, forms a rigid horizontal base part 50 that can be used as a seat. At the Underside of the base part 50 extends in the second horizontal direction Y, a transverse groove 56, which forms a mounting receptacle 53 for the third and the fourth anchoring structure 3.

The side surfaces of the frame unit 5 lying opposite one another in the horizontal direction Y are each provided in their upper region with a mounting receptacle 53 which is designed to correspond to the first and second anchoring structure. The first and second mounting receptacles 53 are preferably arranged congruently with one another in the second horizontal direction Y. The first and second mounting seats 53 are formed by an L-shaped groove. The horizontal leg of the L-previous assembly receiving groove forms a guide 55. The vertically upwardly projecting leg of the L-shaped assembly receiving groove forms a latching groove 54 Mounting projection 33 of the respective anchoring structure 3 turned over. The frame unit 5 is pushed into the building opening 101 in the passage direction D, with the mounting projection 33 of the anchoring structure 3 fixed in a stationary manner to the building wall 100 sliding along the guide 55 . The final assembly state is reached when the locking groove 54 receives the assembly projection 33 . The mounting projection 33 is pushed into the latching groove 54 by the weight of the frame unit 5 ( figure 2 ).

The frame unit 5 implements a panel with an inner visible surface 59, which covers the inner side surfaces 103 of the building opening 101, and a skirt 58 which projects outwards transversely to the passage direction D and which covers the transition edges between the inner side surfaces ios and the inside of the building wall 100.

figure 5 shows an embodiment of a swing-like interior window sill system 1. From the respect of Figures 1 to 4 The version described differs from that in figure 5 Illustrated versions essentially only by the design of the system in the area of the parapet side 103. The building opening 101 can be formed in the area of the parapet side 103 with a surface 107 that is concavely curved with respect to the vertical direction Z. The frame unit 5 can be flat on the parapet side or, as shown here, with a convex curvature 57 in relation to the vertical direction Z. The convex curvature 57 is preferably complementary in shape to the curved surface 107. No anchoring structures are provided in the area of the parapet side 103. In the final assembly state, the frame unit 5 is supported only by the first and the second supporting structure 3 in the upper area of the building opening 101, whose assembly projections 33, which are aligned with one another, define a pivot axis S. The curvature of the bulge 57 and/or the surface 107 can be related to the pivot axis S, in particular as the center of the curvature. At the in figure 5 illustrated embodiment, the frame unit 5 can swing like a swing about the pivot axis S.

figure 14 shows another embodiment of a swing-like indoor window sill system 1. From the respect of Figures 1 to 4 The version described differs from that in figure 14 illustrated embodiments essentially by the arrangement of the anchoring structures 3 and the corresponding mounting receptacles 53. In the embodiment according to figure 14 anchoring structures 3 are only provided on the side reveal sides 103, which are located at the middle height of the building opening 101 in relation to the vertical direction Z. Corresponding to the anchoring structures 3, the mounting receptacles 53 are arranged centrally on the frame unit 5 in the vertical direction Z. The frame unit 5 can be movable about a pivot axis defined by the mounting projections 33 .

Another embodiment of an interior window sill system 1 show the Figures 6-8 . In the final assembly state, the interior window sill system is 1 in figure 8 pictured. figure 6 does not show the frame unit, but the anchoring structure 3 fastened in the building opening 101. The anchoring structure 3 is formed by a box-shaped supporting structure 7. The box-shaped support structure 7 consists of four support plates 71, 72. The four support plates 71 and 72 each have a flat extension.

In the final assembly state shown here, the first and the second support plate 71 are aligned in a vertical plane which is in contact with one reveal side 103 each. The third and the fourth support plate 72 are aligned in a horizontal plane and rest on the parapet side and the lintel side. The four support plates 71 and 72 of the support structure 7 are firmly connected to one another. The first and the second support plate 71 are firmly connected, for example by screws, to the building wall. All support plates protrude in the passage direction D from the building opening 101 into the interior of the building. The sections of the support plates 71, 72 that protrude into the interior of the building form mounting sections 34b. The mounting sections 34b realize the mounting projections 33 of the anchoring structure 3 formed by the supporting structure 7. In the area of the building opening 101, the supporting plates 71, 72 realize flat mounting plates 32b, the outer sides of which form contact surfaces 31.

The frame unit 5 is equipped with mounting receptacles 53 which are complementary in shape to the mounting sections 34b. A collar 58 is formed on the visible side of the frame unit 5 projecting into the building interior and extends over the mounting sections 34b is slippable. The assembly receptacles 53 are formed transversely to the direction of passage D between the collar 58 and the inner visible surface 59 of the frame unit 5 .

The Figures 9 to 13 show another embodiment of an interior window sill system 1 which, in contrast to the ones described above, is attached to the window frame 203 of the window 201. The mounting of the frame unit 5 by means of a box-shaped support structure 7 formed from four support plates 71, 72 is essentially the same as in the case of the above with reference to FIG Figures 6 to 8 described execution.

The attachment of the anchoring structure 3 to the window frame 203 is described with reference to FIG Figures 9 and 10 clarified. The anchoring structure 3 includes a mounting band 32c mounted on the window frame 203 . The mounting band 32c extends all the way along the window frame 203 surrounding the window opening 205 . The mounting band 32c is formed by a frame-shaped metal sheet. The mounting band 32c may be fixed to the window frame 203 with multiple screws. Contrary to the direction of passage D, a plurality of webs 34c protrude from the assembly band 32c. The length of the webs 34c in the passage direction D can, as in figure 9 and 11 shown exceed the depth of the building wall 100. It is conceivable that the frame unit 5 is carried directly by the webs 34c.

As in figure 11 shown, it is preferred that the box-shaped support structure 7 is inserted into a receptacle formed by the webs 34c and optionally fastened to the webs 34c. The webs 34c and the support structure 7 form the mounting projection 33.

The features disclosed in the above description, the figures and the claims can be important both individually and in any combination for the implementation of the invention in the various configurations.
