Description

The invention relates to a spacer, in particular one for a profile system of a window or a door with at least one casement and one frame, with a profile section that forms a ramp block with a ramp that can be positioned in the rebate gap between a rebate surface of a casement profile and an opposite profile is.

Such a spacer should serve in particular to secure a distance to be maintained between a casement profile and an opposing profile, in particular an opposing window frame, opposing casement profile or opposing threshold profile, preferably at least during transport or assembly.

The invention also relates to a method for at least temporarily stabilizing a casement profile, preferably during transport or assembly, in relation to an opposite profile.

According to the invention, “opposite” means that position in which a profile of a casement and the other profile are arranged relative to one another when the casement is in the closed position. In this position, a sash profile and the other profile, e.g. a window frame profile or threshold profile or another sash profile - especially if correct adjustment is assumed - lie parallel to one another and contact each other, in particular at least in the seals.

In conventional profile systems, at least in Europe, the sash frame is generally openably connected to the blind frame via a turn fitting or combined turn/tilt fitting. There is a rebate gap area between the opposing rebate surfaces of the profiles between the casement and the window frame. In order for the fold gap to be uniform in the stretch per profile bar, the gap size should preferably have a defined minimum size. The rebate dimension is the dimension between the rebate surfaces of two parallel frame profiles of the same frame.

In particular, during the curing time of the adhesive on glued glass panes, as well as in general processing, e.g. during assembly and transport, the parallelism between glass edges and rebate surfaces cannot be maintained.

In this way, in practice, there are deviations in the actual fold dimension compared to the target fold dimension, which leads to an uneven fold dimension all around.

It is state of the art to use a so-called ramp block for sash frames that jam due to their weight or inadequate assembly when closing, which is inserted in the rebate area between the sash frame and the window frame and which, via a sloping ramp surface, allows the sash frame to be raised and thus restores the desired fold dimension. Such a ramp block has hitherto been attached to the frame on its rebate surface in order to raise the casement profile if the required dimensions are not met, while it slides over the ramp surface of the ramp block. This is known, for example, from the publication DE 296 18 315 U1 .

In general, and therefore also in the invention, a ramp block comprises a ramp surface which is inclined with respect to the fold surface to which it rests, fastened. Due to the inclination of the run-up surface, the height of the run-up block decreases, viewed from the profile to which it is attached, in the direction of the profile that runs onto the run-up block.

However, this measure only corrects the non-uniform distance and/or angle between the casement and frame after assembly or manufacture, which deviates from the target state, for which purpose the block remains attached to the frame according to the prior art.

The object of the invention is therefore to provide a spacer that not only ensures the rebate dimension and/or the size of the rebate gap all around within a desired tolerance range of a sash frame in a window frame, but which is also capable of other distances, for example the sash gap between two sashes, as with a casement window, to be kept constant. Furthermore, the spacer should preferably be used temporarily on a profile system in order to stabilize it during assembly and/or transport so that the system does not warp. Preferably, the spacer according to the invention can then be removed without tools.

According to the invention, the object is achieved by a spacer which has a first profile section which includes the ramp block and which has a second profile section which includes a fastening means, in particular a receiving groove, with which the second profile section can be fastened to the sash overlap of a sash frame, the first and second profile section are connected to each other to form a step.

The method according to the invention is then characterized in that a spacer, in particular the aforementioned one, is fastened in a clamping manner to the sash overlap of the sash frame profile with a profile section comprising a fastening means, in particular a receiving groove, and with a profile section forming a run-up block in the fastened state in the gap region between the sash rebate surface and the opposite profile is pushed in, in particular when a sash, on whose profile or profiles the spacer is attached, is transferred from the open to the closed position.

The term profile or profile section, in particular in the case of spacers, should not be understood in the sense that the term is necessarily associated with a specific construction, but can preferably be understood in such a way that a profile is a construction made of webs and recesses, in particular cavities, which are at least partially delimited by the webs. Profiles are in particular components that are produced by extrusion or injection molding. A section is preferably understood to be a region of the element referred to, which can be defined in particular with regard to its functionality.

The step formed can preferably result from the fact that a surface of the second profile section pointing away from the wing flap, in particular which forms the outer surface of the receiving groove, is spaced by a step height from the ramp surface of the ramp block, particularly at its thickest point.

This has the advantage that the groove base of the receiving groove and the ramp surface of the ramp block are different in height and that the ramp block is positioned in such a way, despite being attached to the outside of the sash overlap, in particular lying on the inside behind it, that it rests against the rebate surface of the sash and when the same penetrates into the fold gap area of the opposite profile.

A surface area of the spacer, which extends in the height direction between the ramp surface, in particular its end at the thickest point of the ramp block, and the named outer surface of the receiving groove at the same time forms a stop which, after the casement is closed, contacts a surface of the opposite frame profile pointing towards the interior of the room , especially if it is assumed that the casement opens towards the interior of the room. The surface contacted by the stop is that which is contacted by the seal inside the sash rebate without a spacer.

The spacer according to the invention has the advantage that it can be removed, e.g. only clamped to the wing overlap. It is preferably recognizable by the gripping of the flap with the receiving groove walls as a clamping fastening means even after the casement has been closed that a spacer is (still) installed, which means that it still has to be removed again after installation or transport.

Since the spacer can be fastened to the sash overlap and such a spacer is present all around the sash frame, the spacer can preferably basically be placed on each side or each of its profiles on the sash frame. It can thus act against a frame profile, as well as against a door sill profile or another casement profile. The spacer can thus be used universally. Preferably, the receiving groove, as the preferred fastening means, is designed with such a depth that after the spacer has been pushed onto the sash overlap, the ramp block rests with its side facing away from the ramp surface on the rebate surface of the sash frame profile, in particular also in a stable position when the ramp surface is supported by the opposite ramp Profile is force-loaded.

The spacer according to the invention thus comprises two profile sections I and II arranged in steps relative to one another, with the function of the first profile section I being similar to that of a conventional block, e.g achieved, in particular at least in the surface areas of the spacer pointing away from the wing rollover.

Preferably, the invention can provide that the receiving groove comprises a base web forming the base of the receiving groove, from which two spaced opposite clamping webs protrude, between which a wing flap can be accommodated, in particular by clamping. The outer surface mentioned at the outset forms the outward-facing surface of the base web. The clamping webs can preferably interact in a resilient manner.

The distance between the clamping webs can preferably be smaller than the thickness of the wing overlap, at least in certain areas, if the spacer is not yet mounted on the wing overlap. For example, the clamping web facing away from the first profile section, in particular the clamping web pointing towards the interior of the room during assembly, can be inclined towards the interior of the receiving groove or towards the other clamping web. To put on the Spacers on the sash overlap must therefore be increased the distance between the clamping web to add the flashover between them. This creates a holding spring force.

Alternatively, a clamping web, in particular the one pointing away from the first profile section, in particular the one pointing towards the interior of the room, can comprise a screw which can be screwed in through the clamping web in the direction of the other clamping web in order to clamp the wing flap between the screw end face and the other clamping web.

Provision can furthermore be made for the clamping web facing the first profile section to have a groove which is open toward the interior of the receiving groove and extends in the direction of the groove. The seal on the sash rebate can then be accommodated in this when the spacer is placed on the sash rebate. Viewed in the push-on direction, the fillet acts like an undercut and thus contributes to the clamping fastening. Furthermore, due to the fillet, the seal on the wing overlap is less stressed and therefore less deformed. The invention is thus characterized in the second profile section in that it is at least essentially U-shaped, encompasses the wing overlap and enables clamping attachment to the wing overlap. The clamping effect is preferably generated on the one clamping web facing the ramp block by swiveling in and pressing on the wing overlap seal, which is embedded in the seal groove provided specifically for this purpose. The second clamping web can be designed with prestressing for a resilient effect in such a way that a clamping effect occurs as a result.

Depending on the profile combination, the spacer is able to compensate for a sash gap and/or a chamber gap in the rebate area when installed and thus the parallelism between the glass edges and sash rebate surfaces in combination with a window frame or a threshold or a mullion profile that can be moved with a sash frame are connected to ensure.

The special angular step shape enables universal use for various profile combinations.

The spacer according to the invention is advantageously produced in one piece, in particular from plastic, e.g. as an injection molded part or as an extruded part

The invention can provide that, e.g. when forming the window or a door of normal size, at least one spacer per profile bar is used in order to indirectly fix the glazing.

If necessary, the spacers according to the invention can be removed again after the assembly of the casement in the window frame, but they can also remain in the window reveal in the rebate area until after the final assembly of the finished window. In the latter case, the gap dimension is prevented from being changed by an impermissible amount when the window is transported. However, the assembly aid according to the invention is preferably removed again at the latest after the final installation of the window. The U-shaped second profile section II is visible from the outside and the installer has a visual check that the spacer can still be removed.

The spacers are primarily designed for use during the curing time of the adhesive when gluing glass. An additional use of the spacers as transport safety elements can also be provided. It is also possible to leave the spacers in place longer than the minimum required curing time.

According to a preferred embodiment of the invention, the spacer according to the invention is also attached to the opposite frame profile, e.g.

Said step can preferably be formed by a transition of the clamping web facing the first profile section that is angled in the direction of the first profile section, in particular at an angle of substantially 90 degrees, into a ramp web of the ramp block that encompasses the ramp.

The run-up web can preferably have a surface area/web area in the area of the transition, preferably where the run-up block has its greatest thickness, which in the mounted state lies parallel to the rebate surface of the casement profile.

Preferably, the run-up block can be formed in the first profile section by a holding web which stands up from the run-up web, in particular in at least essentially the same direction as the clamping webs and an end web which is spaced apart therefrom. The holding web can be fastened standing up on the aforementioned web area, which lies parallel to the rebate surface of the casement profile. Due to the height of the retaining bar and the thickness of this bar area is thus ins total defines the height or Docke of the ramp block. The ramp bar is thus supported on the fold surface via the holding bar.

The run-up slope of the run-up web is further preferably formed in an area between the holding web and the end web, in particular for which the end web has a lower height than the holding web. The ends of the end web and holding web pointing towards the fold surface preferably lie in a common plane parallel to the fold surface, in particular in contact with it.

In a further development it can be provided that the holding web and the end web are connected by a stabilizing web, in particular which is arranged centrally between the webs in relation to their length in the direction of extension of the receptacle. The stabilizing web then runs at least transversely, preferably perpendicularly, to the direction of extension of the receptacle.

The stabilizing web can preferably have a surface pointing away from the ramp web, in particular which is level with the free ends of the holding web and end web or projects beyond their level, which has a friction-increasing surface design. Such a configuration can be, for example, a structure, preferably a corrugation, or an elastomeric coating.

In particular for further stabilization, the holding web can have a stiffening rib on its side facing the receiving groove. This can preferably drop in height in the direction of the ramp bar/receiving groove. The rib can be arranged, for example, in the center of the holding web in relation to its length in the direction of extension of the receptacle. If there is a stabilizing bar, the stiffening rib can be arranged opposite it, i.e. the stiffening rib and stabilizing bar lie around the holding bar and enclose it between them.

The invention can also provide that the base web of the receiving groove has at least one recess that extends in the direction of the groove and is open to the receiving groove and/or that the base web of the receiving groove has at least one recess in the material thickness of the base web that extends in the groove direction and that is open to the receiving groove closed is.

On the one hand, material can be saved by such recesses, on the other hand, the clamping properties of the spacer in the receiving groove can also be positively influenced.

The invention is explained in more detail below with reference to the drawings.

At the in 1 The profile system 100 shown in cross section is, for example, a window with a window frame 20 and a casement 10 made of standard plastic profiles made of PVC. The rebate gap 24 extends between the casement 10 and the window frame 20. The rebate gap can essentially correspond to the distance between the opposing rebate surfaces of the window frame 20 and the casement 10. The sash frame overlap 11, which in particular extends from the rebate surface of the sash frame in the direction of the frame, covers the visible inner surface of the frame 20 in some areas, in particular by the cover dimension “h”. The spacer 30 used according to the invention forms a U-shaped receiving groove with the opposing clamping webs 1, 1' and the base web 3, in particular with the function of a clamp, in particular a prestressed clamp, which encompasses the wing overlap 11 and holds the spacer 30 together in a resilient manner causes the wing rollover 11.

For assembly, the spacer 30 is pivoted with the clamping bar 1 from the wing flap 11 around this, so that the U-shaped section II is positioned like a cap on the wing flap 11 . For an optimal fit, a sealing groove 2 is formed on the clamping web 1′, in particular adjacent to the inner surface of the base web, in which the wing overlap seal 12 is embedded.

The second profile section II is thus used for clamping attachment to the sash frame overlap, whereas the first profile section II formed thereon forms a ramp block and protrudes into the rebate gap 24 . The ramp block is at least formed here from the end web 8, the holding web 7 and the ramp web 6 extending between them at their ends remote from the rebate surface of the casement profile and forming a ramp here. In this version with two surface sections with different inclinations in relation to the two face surfaces of the opposing profiles. The holding web 7 supports the casement 10 against lowering if the spacer is used on the lower casement. He can also keep the respective rebate gap to size on the other three sides of the sash.

1a shows a detailed view 1 from the spacer 30. This embodiment provides two profile sections I and II. The second profile section II includes, in particular to form a fastening clamp, the base web 3 with the clamping webs 1, 1′ formed on both sides. The base web 3 can preferably have two recesses 4, 4', which serve to save material. These recesses can pass through the base web 3 completely or only in certain areas in the direction in which the receiving groove extends. The stabilizing web 9 with a corrugated surface is intended to prevent a possible displacement of the spacer 30 in the direction of the wing overhang 11 and to minimize the pressure on the wing overhang seal 12 .

The starting bevel 5 of the base bar 3, in 1b shown, the assembly of the spacer 30 and the assembly in the profile combination after 3 facilitate. Apart from a more appealing appearance of the symmetry, the run-on bevel 5' has no further function during assembly, but reduces the material to be used.

The clamping web 1 'extends at a preferably approximately right angle in the run-up web with the run-on bevel 6 and ends in the end web 8 formed thereon, which limits the section I in width. After placing the cap-like profile formation according to Section II, the starting bevel 6 enables the casement to be closed without any problems and the casement to be raised to a defined level.

Apart from the groove, the clamping web 1' is parallel to the end web and retaining web. The clamping web 1 is inclined inwards towards the receiving groove.

The profile section I comprising the headstock extends essentially between the end web 8 and the retaining web 7, which are connected to one another via a stabilizing web 9 which extends between these webs and has a corrugated surface in the embodiment shown. The holding web 7 fulfills the main function of the first profile section. By its height above the ramp bar 6, it defines the distance between the rebate surface of the casement profile to the opposite profile in which 1 i.e. opposite the window frame profile and in 2 compared to the threshold profile. The height corresponds to 1 the size of the gap a, which corresponds to the distance between the rebate surface of the casement profile and the surface of the glazing bead groove. The stabilizing web 9 serves to stabilize the web construction; the web surface facing the rebate surface of the casement can preferably also have a friction-increasing design, in particular a friction-increasing design compared to a smooth surface finish, preferably in order to offer the fitting parts that may be installed in the Euro-groove 15 a high friction resistance. For example, its web surface can be structured, for example corrugated. Alternatively, the surface can also be provided with an elastomeric material, for example rubber, silicone or the like

2 shows a profile system 200, comprising a casement 10, threshold 40 and mounted spacer 30.

In this embodiment, the spacer 30 fulfills the same function as in the profile system 100, only using the example of a threshold. The spacer 30 keeps the space between the wing base web 13 and the tread profile 41 constant with the holding web 7, which corresponds to the gap dimension a' with its height. 2a shows this situation too 2 in detail.

3 shows a profile system 300, comprising an active sash frame 10, and a passive sash frame with mounted cuff profile 50 and mounted spacer 30. The section shows the vertical cuff profile 50 vertically running profile is visible to the naked eye, since there is a wing gap b between the adjacent active and passive wing frames. In order to counteract this undesirable effect of profile curvature, the spacer 30 with the dimension of the wing gap b keeps the active and passive wing frame at a parallel distance from one another. Here, the starting bevel 5 of the spacer 30 fulfills its function on the edge of the outer surface of the base web pointing towards the first profile section. When closing the active casement 10 against the faceplate stop bar 51 of the Forend profile 50, the starting bevel 5 offers a resistance-reduced approach to the forend base web 52. 3a shows the mounted spacer 30 to 3 in detail.
