Description

Closure device for building openings

The invention relates to a closure device for building openings, in particular window openings, of shell structures as anti-theft protection, weather protection or the like.

For buildings that are not yet finished so far that their Openings, e.g.

Door openings and especially window openings, already with appropriate finished doors or windows can be closed, these structural openings remain so long open and unlocked. Usually only one Door opening of a room located inside the house, e.g. in the basement or on the first floor, locked with a temporary, demountable door, so in this room of the otherwise open and freely accessible building construction tools, sanitary parts and other items can be stowed in a roughly theft-proof manner. Because the structure but otherwise remains freely accessible and such, inside the house and thus from Experience has shown that provisional doors that are not visible from the outside are often and can also be broken open very easily, so no reliable anti-theft device either offer, there is ultimately no reasonably reliable one in the shell construction Theft protection.

In addition, the temporary doors mentioned are complex and expensive are, because they are each to be temporarily secured according to the dimensions of the Door opening must be prepared and not on differently large dimensions have it adjusted. Has the structure progressed so far that it is already heated? can be or, depending on the circumstances, is to be heated, so will a significant proportion if the window and / or door openings are otherwise completely open wasted heating energy.

The invention is based on the object of a closure device for building openings, by means of the building openings, e.g. outer window and / or door openings, can be closed quickly and reliably, and thus on the one hand a reliable anti-theft device and, on the other hand, at the same time a tight opening closure is achievable, the Einc heating of the building in this raw state either only makes sense or saves heating energy. In addition, the closure device Reusable from building to building and can be locked to different dimensions Structural openings be adjustable.

In the case of a closure device, the task is the one mentioned at the beginning Kind according to the invention solved by a closure cap that is attached to the outside of the masonry can be placed and then at the edge area all around the building opening and which carries two diagonal struts on its inside, two each detachable fastening devices held thereon in a longitudinally displaceable and adjustable manner wear, each of which is aligned approximately at right angles to the plane of the closure cover Have clamping bolts that pass through the building opening into the interior of the building engages and on which a clamping nut with support device is held, which on rests against the inside of the masonry and can be tightened.

The closure device according to the invention is suitable for essentially any building opening, but especially for external window openings and door openings. It can be attached quickly and reliably and then allows it to be closed Structural openings. This is a reliable anti-theft device and also at the same time a tight opening closure is achieved. The latter heats the building makes sense in the raw state for finished doors and windows that cannot yet be used leads to considerable savings in heating energy. As a result of the fastening devices, which are held longitudinally displaceable and adjustable on the diagonal struts made it possible, the locking device according to the invention from building to building to be reused and in each case to differently large dimensions of each to closing structural openings, in particular window openings.

All parts of the locking device remain unchanged in particular, the size of the closure cap remains unchanged. The adaptation happens only by longitudinally shifting the fastening devices along the diagonal struts that hold them. The cap is used as intended placed on the outside of the masonry, with the diagonal struts tensile strength, but longitudinally displaceable clamping bolt with clamping nut and support device direction through the masonry opening inwards to the inside of the room, namely expediently in the corner area of the masonry opening. The respective support device is then applied to the inside of the masonry. The assigned Tightening nut are tightened, whereby the closure cover against the outside of the Masonry and the support device tightened against the inside of the masonry will. Since the clamping nuts are only accessible from inside the structure a loosening or detachment of the closure device according to the invention from the outside of the building is not possible. The closure device according to the invention thus offers In other words, effective theft protection for all building openings that are freely accessible from the outside z. B. a shell. The closure cover covering the opening in the structure forms thereby a relatively tight opening closure, so that the closed space of the Building can be heated as possible without wasting heating energy. Advantageous is at the same time that the inventive locking device to different Wall thicknesses of the masonry adapt by itself, i.e. for walls of different thicknesses is usable.

An advantageous embodiment provides that the support device is designed as an angle bracket, one angle leg of which is supported on the clamping bolt is and the other angle leg penetrated by the clamping bolt and by means of it the clamping nut can be supported. The angle leg supported on the clamping bolt can run approximately parallel to and at a distance from the clamping bolt and arn free Leg end of a preferably bent support on the outer surface of the clamping bolt is resting. The angle bracket can be made from a curved flat iron, for example be educated.

This then has an approximately U-shape with U-legs of different lengths, from where the longer U-leg is the angle leg penetrated by the clamping bolt, while the shorter U-leg forms the bent support, the end against the clamping bolt is supported. This design of the support device is high stability the latter ensures even when strong Tension forces are applied. At the same time, this embodiment is the support device extremely easy and cheap and at the same time the rough handling on the construction site grown with a long service life.

Another advantageous embodiment provides that the dic diagonal struts are designed as profile struts, preferably with angled, U, T or double T profile in cross section. The invention opens up a wide variety of possibilities here.

In a corresponding adaptation to the cross-sectional shape of the profile struts are then the fastening devices held thereon in a longitudinally displaceable and adjustable manner elected.

Another, particularly advantageous embodiment provides that the profile struts have a substantially C-profile in cross-section, the in The longitudinal direction of the channel-shaped opening of the C faces away from the cap. Further it is advantageous if the fastening devices each have a holding and guide element have, which clasps the profile strut or is held within it and which is arranged displaceably on the profile strut for longitudinal adjustment purposes is. In an advantageous further development, the holding and guiding element can e.g. be formed on the clamping bolt at the end attached sliding block, the inside of the C-profile is non-rotatable, but arranged to be displaceable. Through this design is, on the one hand, a secure attachment of the clamping bolts at the end of the profile struts realized and on the other hand at the same time an unrotatable anchorage with simple means the clamping bolt on the profile struts, as well as easy longitudinal displacement the clamping bolt along the Plofil struts. Thus, by moving the sliding blocks the locking device according to the invention on the clamping bolts along the profile struts can be adapted quickly and easily to different dimensions of building openings, all other components of the closure device remain unchanged. the Edge dimensions of the closure cover are selected, for example, in such a way that they correspond to a given Maximum size of usual structural openings correspond, so that then with smaller ones Opening dimensions of building openings by adapting the locking device can be used unchanged.

In a further advantageous embodiment, the invention provides that each diagonal strut is divided into two half-struts, each about attached, in particular welded, to a central piece in the center of the closure cover are. In an advantageous further development, the closure cover has at least one square frame on, the frame opening on the entire surface with a plate-shaped access lock is lined. The penetration barrier can consist of a plate and / or a metal grid be educated. You can also have a plastic film on the facing away from the closure cover and have the inner side of the metal grid facing the fastening devices, provided that the penetration barrier has a metal grille instead of a plate. In this case, the plastic film forms a tight opening closure that the Possibility of heating the building rooms opened up. The metal grid forms one effective anti-theft protection against reaching through or getting through. Instead of metal grilles with plastic film, a continuous plate, e.g. made of sheet steel, are used.

It is also advantageous if the central piece has an inner plate, to which the four half struts are attached, in particular welded, and further has an outer cover plate, by means of which the access lock, in particular the metal grille and the plastic film, via one or more screws on the Inner plate are clamped. Via the half-struts firmly attached to the square frame, at the central ends of which, in turn, the inner plate is firmly arranged, can thus fixed by means of the outer cover plate and one or more screws on this Frame the access barrier can be attached easily, but theft-proof.

The square frame of the cap is expediently made of corner formed angle profiles welded together, in each of their corner areas one Half strut is welded in at the end.

It can also be advantageous if, in addition to the internal, the Half struts carry the square frame, another outer square frame is provided is, which is placed on the inner square frame in such a way that both square frames between parallel ones, extending approximately within the plane of the closure cover Frame legs delimit a circumferential gap that is roughly U-shaped in cross-section, in the access barrier all around the edge, in particular that Metal grid with plastic film is held. The outer square frame serves on the one hand for further reinforcement of the closure cover. Above all, this is the penetration barrier even more reliable and firmly anchored.

It can also be advantageous if the metal grille on the outside Square frame attached, e.g. welded, and if the plastic film on the Outside of the inner square frame is held. Like the inner square frame, so the outer square frame can also be made from angle profiles welded to one another at the corners, but preferably with a larger dimension than the inner square frame be. Furthermore, the outer square frame can also be fitted with the inner four be welded to the corner frame.

Details and advantages of the invention are given below with reference to a Explained in the drawings embodiment shown. They show: FIG. 1 a schematic front view of a locking device for building openings, FIG. 2 shows a schematic section along the line II-II in FIG. 1, FIG. 3 shows a schematic section along the line 111-111 in Fig. 1, on a larger scale, FIG. 4 shows a schematic perspective view of the lower left corner area in FIG. 1, FIG. partly seen in section and from the inside of the building.

The closure device shown in the drawings is general for building openings in shell structures for theft protection, as weather protection or the like. determined, but especially for window openings 10 in the masonry 11. The Closure device has a generally designated 12 closure cover on, which can be applied to the outside 13 of the masonry 11 according to FIG. 2 and then around the window opening 10 along its edge area on this outer side 13 is essentially tight.

On its inside, the cap 12 has two diagonal struts, each of which is divided into two half-struts 14, 15 and 16, 17, respectively. All four Half struts 14-17 are approximately in the center of the closure cover 12 on an inner plate 18 welded to a central piece there.

Each Haltesftebe 14-17 carries a longitudinally displaceable and adjustable held, releasable fastening device with one designed as a sliding block Holding and guiding element. Such a sliding block 19 or 20 is only with regard to the half strut 14 and 17 can be seen in Fig. 3 and 4, respectively. Each sliding block 19 and 20 is displaceable within the associated half-strut 14 or 17, but cannot be rotated arranged. In the same way there are also in the half struts 15 and 16 corresponding, invisible sliding blocks.

The four individual fastening devices associated with each half-strut 14-17 also have four individual clamping bolts that are approximately at right angles to the plane of the Closure cover, 12 are aligned, through the window opening 10 through into the Grab the inside of the structure and on each of which a clamping nut at this inner end is held with an associated support device, which in turn on the inside 21 of the masonry 11 rests and can be fixed there. This previously described The design of the fastening devices is shown in the drawing can also only be seen for the half strut 14 and the half strut 17. So is on Sliding block 19 of the half strut 14 has a clamping bolt 22 with its end on the left in FIG. 3 attached, e.g. welded on. The clamping bolt 22 has at the right end in FIG. 3 a threaded shoulder 23. On the latter is a clamping nut 24 with it fixed Hand lever 25 screwed on. The clamping nut 24 is a support device 26 on this assigned to the right end of the clamping bolt 22.

In a corresponding manner, the other sliding block 20 engages within the half strut 17 (Fig. 4) with its left end to a clamping bolt 27, which is on The right end is provided with a threaded shoulder 28 on which a clamping nut 29 is screwed is.

The latter is also for rotary actuation with a hand lever fixed to it 30 provided.

The clamping nut 29 is also designated generally by 31 Stutzé device assigned.

The same design of clamping bolts is still available twice, namely once for the half strut 16 and on the other hand for the half strut 15.

Each support means is, like support means 26 and 31, as Formed angle bracket, which is made, for example, from a bent flat iron. For the sake of a better overview, there is the further design of this vertebral bow explained only with reference to the support device 26 (FIG. 3). Its an angle leg 32 runs approximately in pairs to and at a distance from the clamping bolt 22 and carries on the free, in Fig. 3 left leg end a bent support 33, which is on the front The narrow surface is something excepted and there on the outer surface of the clamping bolt 22 rests, so that this angle leg 32 is thus supported on the clamping bolt 22 is. The other angle leg 34 of the bracket is from the threaded shoulder 23 of the The clamping bolt 22 passes through and is supported on the latter by means of the clamping nut 24. The angle leg 34 is at the free end slightly to the inside 21 of the masonry 11 cranked out.

As can be seen from the drawings, each half-strut is 14-17 designed as a profile strut, each in the embodiment shown Has cross-section C-profile. The opening is channel-shaped in the longitudinal direction of the C facing away from the cap 12. Thus engages in this gutter-like opening of the C the respective clamping bolt, as is the case for the clamping bolts 22 and 27 of the C-profiles 14 and 17 can be seen.

In other, not shown exemplary embodiments, the profile struts also have a different cross-section, e.g. angle, U, T or double T profile. The holding and guide elements held on the respective clamping bolts for each profile strut Depending on the cross-sectional design, the latter can either clasp the profile struts or, as shown in the exemplary embodiment, within these profile struts be held.

The closure lid 12 has an inner square frame 35 and is on its frame opening over the entire surface with a plate-shaped access lock lined. In the embodiment shown, the latter is made of a metal grid 36 formed with deposited plastic film 37. Instead, you can in an exemplary embodiment not shown, the penetration barrier, for example, also off a sheet metal plate.

As FIG. 3 shows in particular, the inner square frame 35 is made of Formed corner profiles welded to one another, in their corner areas the half struts 14-17 are welded in each case. The inner square 35 is aligned so that an angle leg with its right narrow surface in Fig. 3 on the outside 13 of the masonry 11 ejects, while the other frame legs 38 each run vertically. The plastic film 37 can be on the outside of this vertical frame legs 38 of the inner square frame 35 be held.

Is used to hold the metal grid 36 and the plastic film 37 Furthermore, a central outer cover plate 39 which rests on the outside of the metal grid 36 and by means of the metal grid 36 and the plastic film 37 in the center above one Screw 40 are tightened on the inner plate 18.

In addition to the inner square frame 35, there is the closure cover 12 also provided with an outer square frame 41. The latter is also off Angle profiles welded to one another at the corners formed, which, however, in comparison to those of the inner square frame 35 are larger. The angle profiles of the outer square frame 41 are aligned in the same way as those of the inner Square frame 35. The outer square frame 41 is on the inner square frame 35 is set up in such a way that between the outer frame legs 38 of the inner Square frame 35 on the one hand and the outer frame legs 42 of the outer square frame 41 on the other hand results in a U-shaped gap in cross-section in which the metal grille 36 and the plastic film 37 are held all around the edge (Fig. 3). The metal grille 36 can be attached, e.g. welded, to the outer square frame 41. Furthermore can both square frames 35 and 41 are also welded to one another to form a single unit be.

Fig. 1 shows that the edge dimensions of the closure lid 12 are chosen to be so large are like the maximum size of a window opening to be closed 10. This maximum size is indicated in FIG. 1 with dash-dotted lines 43. Should a window opening 10 of this size be closed with the closure device the closure cover 12 is attached to the outside 13 of the masonry 11 created, whereby the window opening 10 is covered over the entire opening area is. The clamping bolts engage through the window opening 10 of the masonry 11 through to the inside (Fig. 2).

The tensioning bolts run as shown for tensioning bolts 22 and 27 is, for example in the corner area of the window opening. By tightening the clamping nuts 24 resp. 29 is then achieved that the closure cover 12 in Fig. 3 from left to right is tightened against the outside 13 of the masonry 11, while the support device 26 is clamped in the opposite direction to the inside 21 of the masonry 11.

If this locking device is to be released, this is done by Loosen all four clamping nuts. The respective support devices can then be pivoted away so that the closure cover 12 is pulled off to the left in FIG. 3 can be.

In Fig. 1 with dash-dotted lines 44 is a smaller size a window opening indicated. Should the closure device for the closure of a serve such window opening, the procedure is the same. To adapt on the smaller window size 44 it is only necessary before tightening the individual sliding blocks, such as the visible sliding blocks 19 and 20, along their associated half struts 14 and 17 in the direction of the center around a corresponding Move measure.

The closure device can then be tightened in the same way will.
