"FALL PROTECTION MOUNTING SYSTEM"

The invention relates to a fastening system for fall protection systems on a window frame or a door frame.

In the case of windows or doors, in particular in the case of patio doors, which as a door provide a window-like opening outside the ground level, e.g. These are usually anchored in the masonry from the outside or are already integrated into the window or door.

One problem with these fall protection devices is the lack of the option of retrofitting existing windows and doors. Retrofitting is particularly problematic if additional shading or shutters have to be taken into account, which must not be impeded in their function by the fall protection devices. This problem occurs, among other things, when windows and doors are renovated, for example when they have to be replaced with new windows or doors. There is also a problem with retrofitting if, for example, attachment to an external facade is not possible due to building regulations or monument protection.

Solutions are known from the prior art, e.g. from DE 2020 131 105 162 U1 or DE 20 2005 003 781 U1, which allow a fall protection device to be attached via clamping devices or damage to the visible side. DE 10 2017 1018 090 A1 discloses a holding means in the form of a window rebate bracket, which, however, cannot absorb sufficient forces for fall protection.

The object of the invention is to provide a fastening system for fall protection which overcomes the disadvantages mentioned.

[0006] DE 10 2017 108 090 discloses a fastening element which is arranged in the rebate of a window or a door. The disclosure of this patent application is incorporated by reference and incorporated herein by reference.

The holding system according to the invention for holding an object, in particular a fall protection device, comprises at least two, preferably four holding means. Each holding means comprises a fastening means and a connecting means. The fastener is connected to a stationary frame of a window or door. The connecting means is guided through a passage area between the stationary window frame and a rotatable or sliding closure element of the window, in particular the window sash, or the door, in particular the door leaf, into an outside area in front of the window or in front of the door. The fastening means is in a form-fitting and/or force-fitting connection with a building wall adjoining the fixed window frame and the connecting means comprises at least one, preferably several, sleeves. The one or more sleeves at least partially accommodate the fastening means in their interior space.

The fasteners, e.g. dowels or screws or combinations thereof, which are accommodated in sleeves, improve transverse forces in the form of tensile forces on the connecting means in the building wall and, if necessary, but not necessarily, proportionally also in the window frame. Forces acting on the holding system are thus absorbed and transmitted. In this way, a stable and secure attachment of the holding means can be guaranteed and the holding system can be installed without damaging the outer visible side (outside) of the window or the door or the facade.

By using a holding system according to the invention, it is possible to provide a force-loaded object, e.g. fall protection or an attachment point for e.g.

In a particular embodiment it is provided that at least one sleeve protrudes through the stationary window frame into the adjacent building wall.

By forming the sleeve in the appropriate length, forces acting on the retaining system are transmitted through the sleeve itself to the adjacent building wall, thus ensuring a stable fixation of the retaining system.

An advantageous embodiment of the invention provides that the connecting means comprises at least one middle section and at least two opposite end sections adjoining the middle section.

Due to the contour resulting from the sections, the connecting means can follow the contour of a window rabbet or door rabbet with its sections, and thus penetrate into an outside area without damaging or changing the window or door.

It is further provided that the connecting means comprises a central section in which the connecting means has a thickness of at most 2 mm over a length of at least 0.5 cm, and in particular at least 2 cm.

The central section when the retaining system is installed is in the passage area of the window or door, in the so-called fold. The connecting means (6; 306) preferably has a width of at least 5 mm and at most 70 mm in its middle section.

[0016] As a result, the connecting means can be introduced into the passage area of a window or a door without impeding the function, such as opening and closing. This enables subsequent installation on existing windows or doors. The dimensioning allows sufficient force absorption and stability to fulfill the required functions of the attachment, e.g. fall protection.

In a particular embodiment it is provided that the connecting means outside the window or door level in front of the window sash or door leaf, on the outside of the building, comprises at least one receiving means for a cross brace, in particular an insertion iron for a cross bar.

A receiving means enables a flexible combination of the individual connecting elements, for example by means of a crossbar, as a result of which the holding system in the composite has greater stability.

It is further provided to arrange the fastening means on a first end portion of the connecting means and the receiving means for a cross brace on a second end portion of the connecting means.

This creates a dimensionally stable connection between the masonry and the cross brace, which stabilizes the holding system against the effects of force on the cross brace.

In a moreover preferred embodiment it is provided that the fastening means is bent by 90° between a first end section and the middle section and that the fastening means is bent in particular by 90° between a second end section and the middle section. A first bending edge formed thereby and a second bending edge formed thereby should therefore run parallel.

The angle sections are bent in opposite directions, so that a kind of Z-shape is created. This allows the retaining means to be placed in a window or door rebate, following the contour of the rebate.

As a result, the fastening means and the receiving means are offset from one another and arranged in parallel. As a result, the forces acting on the holding system are diverted and optimally distributed, and a combination of two holding means in each case is made possible by a crossbar.

It is further provided that the fastening means for producing the connection

includes a threaded connection and/or a positive connection. For example in the form of a screw, comprising a screw and a dowel, a pin and a dowel and/or having an adhesive connection.

As a result, the holding means is securely attached to the frame and / or in the masonry. Adhesive cartridges for insertion into the sleeves are also conceivable.

In a preferred embodiment it is provided that the passage area is formed by a rebate area between a frame and a wing or that the passage area is formed by a gap area between a roller shutter rail and a roller shutter curtain.

A flexible use of the holding system is also possible in the presence of roller shutter systems.

In a preferred embodiment, the holding means can be designed in such a way that a fall protection, e.g. In this way, opposing holding means are braced by the profile crossbar.

In addition, provision can also be made for the fall protection to be held laterally, at the height of, for example, safety glass by a profile. In this way, the superimposed holding means are connected to each other on each side and are braced together transversely by the fall protection.

It is also provided, for example, that a wire can also be stretched between the holding means, or that an embracing can be formed along the length of the window rebate anchor.

A particularly preferred embodiment provides that the sleeves at least partially comprise a perforation as an opening in the region of their lateral surface, the perforation in particular breaking through the lateral surface in its longitudinal extent only in sections, in particular in an end section.

A perforation makes it possible in an improved manner to introduce the holding means into the masonry by means of an adhesive connection. Through the perforation and the associated opening in the lateral surface, an adhesive introduced through the sleeves, in particular pressed in, can escape laterally from the sleeve through the perforation. In this way, an adhesive connection is already produced in the area of the lateral surface and the openings, which leads to increased stability.

In a moreover preferred embodiment it is provided that the sleeve or the sleeves are connected to an end section via a detachable connection, for example via threads or other form-fitting connections. In this way the angled section can be detached from the sleeves without having to remove the sleeves from the frame and brickwork.

Further details of the invention are described in the drawings with reference to exemplary embodiments shown schematically.

Here shows:

[0036] FIG. 1 shows a schematic top view of the holding system according to the invention when installed on a window frame adjacent to a masonry;

[0037] FIG. 1a shows a special variant with a multi-part fastening means between the sleeve and the masonry;

[0038] FIG. 2 shows a schematic front view of the holding system according to the invention when installed on a door;

[0040] FIG. 3 in variants a) to f) a schematic representation of different configurations of the receptacle of the holding system;

[0040] FIG. 4 shows an embodiment of a holding system.

Figure 1 shows a schematic plan view of an arrangement by means of the holding system according to the invention of two holding means 2a and 2b in the installed state on a masonry 8 and a window frame 9. The holding means 2a is at a first end 3a via a preferably welded sleeve 5 through the Frame 9 of a window or door connected to the masonry 8. The connection is made using a fastener 4 (shown in phantom), which can be designed, for example, as a screw, as a dowel-screw system or as an adhesive anchor or adhesive dowel.

At a second end 6a of the holding means 2a there is a receiving means 7a to which a crossbar 10 or another holder for an object to be attached is attached by means of connecting means, e.g. plug connections.

The crossbar 10 is also held at its other end by the further holding means 2b, which is fixed according to the embodiment described above. The window width is broken here and does not correspond to the actual proportions.

The bending edges 11 and 12 of the holding means 2a visible in this illustration ensure that the holding means 2a can be pushed through a passage area along the rebate contour between the fixed window frame 9 and a rotating or sliding closing element of the window or door (the window or door sash )--not shown--into an outside area-A-located in front of the window or in front of the door. Damage to the visible side 13 of the frame 9 or the outer facade 14 of the masonry 8 is avoided.

FIG. 1a shows a section of a special embodiment in which the holding means 102 is fastened by means of a multi-part fastening means 104.1 and 104.2. A first part 104.1 creates a connection between the sleeve 105 and the masonry 108 and a second part 104.2 creates a connection between an end section 111 of the holding means 102 and the sleeve 105.

By way of example, but also applicable to the other embodiments, the sleeve 105 shows a structure along its inner wall, in particular elevations 112 or a thread turn or projections for supporting a screwed-in thread or elevations 113 of a fastening means 104.1 or 104.2, e.g. a screw.

In the version shown, the fastening means 104.1 connects the end section 111 to the sleeve 105 in that the screwed-in fastening means 104.1 presses the end section 111 against the sleeve with a screw head 116. In this way, the angle element (end sections 111 and 114 and central section 115) of the holding means 102 can be removed by loosening the fastening means 104.1 and reattached at a later point in time.

Figure 2 shows a schematic front view of the holding system according to the invention when installed on a door 20. Left and right of the door leaf 21, the holding means 22a and 22b are embedded in the frame 29 and in Mauerwerk28 (not shown shaded) attached. For this purpose, the sleeves 25 extend through the window frame 29 into the masonry 28 and accommodate, for example, screws, screw-dowel systems or adhesives and combinations thereof. Reference is made here to the statements relating to FIG.

Arranged below the holding means 22a and 22b are further holding means 22c and 22d, which are used to fasten the holding system on the underside.

A crossbar 27a, which serves as the upper frame of a fall protection 26, is attached to the holding means 22a and 22b. A further crossbar 27b, which serves as a lower frame part of a fall protection 26, is correspondingly attached to the holding means 22c and 22d. A grid, for example, can be arranged between the crossbars 27a and 27b, as shown here. Other variants, such as a glass or the like, are also readily available

to fix.

[0051] FIG. 3a to FIG. 3f shows various configurations of receiving a fall protection device via a holding system according to the invention. Here only the variants of the attachment of the fall protection are referred to. For the attachment of the holding means, reference is made to FIGS. 1 and 2 explained above, in particular as an equivalent or alternative to the crossbars 27a and 27b. The connecting means is shown here and is provided with the reference number 300 throughout.

In a preferred embodiment according to FIG. 3a, the holding means can be designed in such a way that a fall protection, e.g. In this way, opposing holding means are braced by the profile crossbar 301.

According to FIG. 3b, provision can also be made for the fall protection to be held by a profile 302 laterally, at the height of, for example, safety glass. In this way, the superimposed holding means are connected to each other on each side and are braced together transversely by the fall protection.

It is also provided, e.g. according to FIG. 3c, that a wire 303 can also be stretched between the holding means, or according to FIG.

Fig. 3e in turn shows a variant in which both a screw mount or bolt mount 305.1, or alternatively or additionally a clamping jaw mount 305.2 is shown.

Finally, but not conclusively, FIG. 3f shows a receptacle 306 in front of the frame, as can also be designed with facade overlapping for decorative purposes, for example.

Anchorages for scaffolding can also be provided in the manner described above, for example.

4 shows an illustration of an embodiment of the holding means 40 with bent angle elements for a holding system according to the invention. The holding means 40 comprises a plurality of sleeves 45 which are arranged on a first end section 41 of the holding means 40 . The end section 41 also includes bores 42, with which the holding means can be fastened to a frame of a window or a door (not shown) using screws.

The holding means 40 further includes a second end portion 43, which carries a receiving means 44 for a cross brace, a profile or the like.

The first end section 41 and the second end section 43 are connected to one another via a middle section 46 . In the present version, the end sections 41 and 43 are formed onto the central section 46 as angle elements bent by 90° at the fold lines 41a and 43a. The direction of the fold is in each case exactly opposite to the central section, so that the end sections 41 and 43 run in mutually parallel planes. A corresponding different arrangement of angles is conceivable if the course of a window or door rabbet, which the contour 47 of end sections 41 and 43 and central section 46 must follow, requires this.

By way of example, a perforation 48 is provided on the sleeve 45a shown on the left here. The perforation 48 includes a plurality of holes 49, which are only partially shown here for reasons of clarity. A corresponding perforation 48 can be provided in all sleeves 45 or only in some sleeves 45 that are proportionate.

The perforation allows the holding means 40 to be glued to the masonry and/or a window frame of a window or a door in the region of the lateral surface of the sleeves 45 during assembly. If in the cavities 50 of the sleeves 45 an adhesive or

The like pressed, so this can emerge from the perforation 48 and create an adhesive bond.

The lateral surfaces of the sleeves 45 are particularly preferably provided with a surface structure which allows a good adhesive connection.

The invention is not limited to the embodiment of the holding means 40 shown. Variants of other dimensions with more or fewer sleeves are also conceivable and encompassed by the inventive idea.
