GUIDE RAIL ASSEMBLY FOR AN OPENING LIMITER · OPENING LIMITER WITH SUCH A GUIDE RAIL ASSEMBLY AND LEAF ARRANGEMENT WITH

SUCH AN OPENING LIMITER

The present invention relates to a guide rail assembly for an opening limiter for a sash of a window, door or the like. Fer ner, the invention relates to an opening limiter with a guide rail assembly according to the invention and a sash assembly with a sash of a window, a door or the like and a frame that is equipped with an opening limiter according to the invention.

Opening restrictors are devices or fittings for windows, window doors, doors or the like, by means of which the opening angle of the sash of the window, the window door or the door can be limited. In addition, such an opening limiter can have a guide rail which is mounted in a fitting groove of the sash or the associated frame, with a carriage articulated to a first end of a limiting arm being arranged in the guide rail, which slide can be displaced between a first position by the guide rail , which corresponds to a closed position of the wing, and a second position is slidably guided, which corresponds to an open position of the wing. The second end of the limiting arm is connected in an articulated manner to the part of the sash and the window frame on which the guide rail is not arranged. So if the guide rail is mounted on the sash, the second end of the limiting arm is attached to the frame. directs; however, if the guide rail is mounted on the frame, the second end of the limiting arm is hinged to the sash.

Since the slide, which can be moved in the guide rail, is coupled to the wing or the frame via the limiting arm, the slide is moved in the guide rail when the wing is pivoted.

In order to limit the opening angle of the sash, the guide rail has an end stop against which the carriage strikes when the sash is opened, whereby the maximum opening angle of the door is limited in the desired manner.

However, if the slide hits the end stop without braking in the manner described above, this can lead to undesired damage to the opening limiter and other fittings of the sash. In particular, if, for example, the wing is pushed open by a gust of wind, it can happen that the slide hits the end stop with full force, which can damage the opening limiter.

In order to prevent such damage, a reversible and in particular elastically deformable damping unit can be provided between the end stop and the slide, which can prevent the slide from striking the end stop without braking. Rather, such a damping unit can absorb the kinetic energy of the wing, so that the slide does not hit the end stop without braking.

However, since the slide hits the damping unit every time the sash is fully opened, the damping unit can deform over time and / or its intended alignment due to its deformability. change direction in the guide rail, which can ultimately lead to the damping unit falling out of the guide rail or being pushed out so that the carriage can hit the end stop without braking, which causes the problem of damage described.

The invention is therefore based on the object of providing a permanently ordnungsge Permitted damping function of an opening restrictor for a wing of a Fens age, a door or the like.

This object is achieved with a guide rail assembly with the features of claim 1 and in particular in that the damping unit comprises a reversibly deformable and, in particular, elastic or viscoelastic damping element and at least one fold element connected to the guide rail in a captive manner, by means of which the damping element is retained in the guide rail is.

The guide rail assembly according to the invention thus has a guide rail in which a slide is arranged which can be coupled with one end of a limiter arm, the other end of which can be hinged to a wing or to a frame. The carriage is displaceably guided by the guide rail between a first position, which corresponds to a closed-end position of the wing, and a second position, which corresponds to an open position of the wing. Furthermore, the guide rail assembly has an end stop which is arranged in the guide rail and which prevents the slide from being displaced beyond the end stop, so that the displacement path of the slide in the direction of its second position is limited. The guide rail assembly also includes a damping unit between the guide rail End stop and the slide, which according to the invention have a reversibly deformable damping element, which can in particular be elastic or viscoelastic, and at least one retaining element connected to the guide rail, through which the damping element is retained in the guide rail.

The damping unit thus has two different components, namely the damping element on the one hand and the at least one holding element on the other, these components having different functions: The damping element serves to absorb energy from the wing when the slide is in contact with the damping element when the wing is opened got. In contrast, the at least holding element does not serve to absorb energy, but to secure the damping element in the guide rail when it is deformed as intended. The holding element is thus a kind of securing clip, by means of which the damping element can be held captively in the guide rail even if it is deformed due to the carriage hitting the damping element. Since the holding element is slidably guided in the guide rail, it does not prevent the damping element from deforming when it is impacted by the slide.

Preferred embodiments of the invention will now be discussed below. Further embodiments can also emerge from the dependent claims, the description of the figures and the drawings.

For example, according to one embodiment, the damping element can be made of an elastic plastic material and the holding element can also be made of a plastic material, which is, however, more rigid, than the plastic material of the damping element. For example, the damping element can be made from a polymer material such as polyurethane, this polymer material preferably being foamed. The material Vulkollan ^{® from} the Covestro Group or the material Cellasto ^® from BASF, for example, are cited as exemplary materials for the damping element. In contrast, a plastic material with a low coefficient of friction, such as PTFE or the like, can be used for the holding element.

According to a further embodiment, it can be provided that the damping element has a first and a second end, between which it extends in the longitudinal direction of the guide rail, the damping unit between the two ends of the damping element and preferably a holding element in the middle thereof has, which is connected to the damping element. The damping element thus forms two damping sections on both sides of the essentially centrally arranged holding element, one of which comes into contact with the end stop and the other with the slide when it approaches its second position. The damping element can thus be made relatively long without the risk of it being pushed out of the guide rail due to deformation, since it is securely held in the guide rail by the holding element.

In order to prevent one or both ends of the damping element from being pushed out of the guide rail when the carriage comes into contact with the damping element, it can be provided according to a further embodiment that the damping unit is on both sides of the center between the two ends of the damping element and preferably in the vicinity of the two ends of the damping element each has a verbun with the damping element holding element. The two ends of the damping element will be thus in each case prevented by a holding element from being pushed out of the guide rail by the carriage, whereby a particularly reliable damping function can be ensured.

In order to prevent the damping element from bulging out of the guide rail approximately in the middle between its two ends when the slide hits the damping element as a result of the opening of a wing, additional Lich to the embodiment described above, in which at the two ends of the A holding element is provided between the two ends of the damping element, preferably in the middle of the same, a holding element connected to the damping element can be provided in order to prevent the damping element in the middle between its two ends from the guide rail can bulge out.

A plurality of holding elements, for example two, three, four or even more holding elements, can thus be provided along the damping element and connected to the same, so as to reliably hold the damping element in the guide rail. The damping element can thus be made relatively long in favor of its damping effect without the risk of it bulging out of the guide rail or being pushed out of the guide rail when the carriage comes into contact with the damping element.

According to a further embodiment, the guide rail, viewed in cross section, can essentially have the shape of a C-profile. This C-profile can differ from a U-profile in that it has two freely protruding flanges lying in one plane, the free ends of which define a slot extending in the longitudinal direction of the guide rail through the free ends of the the flange in question is limited. This slot is the one that receives the damping element Interior of the guide rail accessible, in which the at least one Hal teelement is held captive by the two flanges. The at least one holding element is thus held losersi cher in the interior of the guide rail by the flanges of the guide rail defining the slot in question.

According to another embodiment, the at least one holding element, viewed in cross section, can have an essentially U-shaped connecting section, the outer contour of which is essentially complementary to the inner contour of the guide rail, so that the outer contour of the connecting section essentially corresponds to the inner contour of the guide rail to out of this in the longitudinal direction of the guide rail to who the. The two flanges of the guide rail, viewed from the inside of the guide rail, partially engage behind the connecting section, so that the holding element and thus the damping unit cannot detach from the guide rail. It can preferably be provided that the free ends of the two flanges engage in corresponding receiving grooves that are formed on the holding element.

In order to ensure particularly reliable guidance of the damping unit in the longitudinal direction of the guide rail, it can be provided according to a further embodiment that the at least one holding element has a guide section that extends outward through the slot of the guide rail and its width corresponds essentially to the width of the slot or the width of which is slightly smaller than the width of the slot. The Hal teelement is thus guided by means of the guide section in question in the slot.

According to a preferred embodiment, it can be provided that the guide section in question, the two flanges of the guide slide ne viewed from the inside of the same from behind. The guide section, together with the connecting section of the holding element, can form corresponding receiving grooves for the two flanges of the guide rail, which can be particularly reliable in preventing the holding element from becoming detached from the guide rail.

According to yet another embodiment, it can be provided that each of the flanges of the guide rail has an outer surface which is inclined in such a way that the respective flange tapers in the direction of its free end. In this case, that section of the guide section with which it engages behind the respective flange can have a guide surface running parallel to the outer surface of the respective flange, so that the guide section has a substantially dovetail shape when viewed in cross section. This makes it possible that the retaining element and in particular its sen guide section does not protrude beyond the outer contour of the guide rail, which could otherwise lead to the free mobility of the Hal teelements in the longitudinal direction of the rail by adjacent components such as a sash or a frame is affected.

In order to be able to secure the at least one holding element to the damping element, it can be provided according to a further embodiment that the damping element has an indented section for each holding element, which has a reduced cross section compared to the damping sections between these indented sections, which is fitted into the Hal teelement and in particular in its U-shaped connecting portion. If the connecting portion of the holding element in cross-section seeks, for example, a U-shaped or fork-like shape, this connecting portion can accommodate the indented portion in question with a reduced cross-section in such a way that the connecting portion with the adjacent damping sections of the damping element is substantially flush.

According to a further aspect of the present invention, an opening limiter is provided which comprises a guide rail assembly as described above, the carriage being articulated to a first end of a limiter arm, the second end of which is connected to a sash of a window, a Can be hinged door or the like or a frame.

According to yet another aspect of the present invention, a sash arrangement with a sash of a window, a door or the like and a frame with respect to which the sash is pivotable is created, this sash arrangement comprising the opening limiter described above, the guide rail of which is in a fitting groove of the sash or the Blendrah mens is arranged, wherein the second end of the limiting arm is articulated to that part of the wing assembly on which the guide rail is not arranged.

In the following, the invention will now be described purely by way of example with reference to the drawings, in which:

Fig. 1 shows a bottom view of a wing assembly equipped with an opening limiter according to the invention in a partially open position;

Fig. 2 shows the wing assembly of Fig. 1 with the wing fully open; Fig. 3 is a perspective view of an inventive

Shows guide rail assembly including a limiter arm;

FIG. 4 shows a perspective and somewhat enlarged illustration of the damping unit recognizable in FIG. 3;

Fig. 5 shows an exploded perspective view of the damping unit of Fig. 4; and

Fig. 6 shows a cross section through the guide rail and the damping unit received thereby in the region of a Hal teelements.

1 and 2 show a wing arrangement 10 according to the invention, the wing 12 of which is only schematically indicated in FIG. 1 in a partially open position relative to the frame 14 (likewise only indicated schematically) of the wing arrangement 10. In contrast, FIG. 2 shows the Flügela arrangement 10 with the sash 12 fully open, which may be, for example, a window that can be pivoted with respect to the frame 14 or a door or window door that can be pivoted with respect to the frame 14.

In the embodiment shown here, the guide rail 22 of the Publ voltage limiter 20 is arranged and mounted in a fitting groove on the underside of the wing 12, whereas the second end of the limiting arm 24 is hinged to the frame 14. Equally, however, the guide rail 22 could also be arranged on the frame 14 and the second end of the limiting arm 24 could be articulated to the wing 12. The guide rail 22 has a substantially C-shaped cross-sectional profile (see in particular FIG. 6), which defines an interior space 40 in which a slide 26 is arranged, which is slidable by the guide rail 22 between a first position, which is a corresponds to the closed position of the wing 12, and a second position is displaceably guided, which corresponds to an open position of the wing, as shown in FIG.

At both ends of the guide rail 22 an end stop 28 is arranged in the same and firmly connected to the guide rail 22, which prevents a displacement of the carriage 26 beyond the respective end stop 28 addition. If the wing 12 is therefore pivoted from its closed position beyond the intermediate position in FIG. 1 into its completely open position according to FIG. 2, the slide 26 is articulated due to the fact that it is connected to the first end of the limiting arm 24 , moved from its first position, which corresponds to the closed position of the wing 12, into its second position, which corresponds to the open position of the wing 12. Here, the carriage 26 encounters a reversibly deformable damping unit 30, which is arranged in the interior 40 of the guide rail 22 between the end stop 28, which is assigned to the second position of the carriage 26, and the carriage 26. The carriage 26 thus does not impact directly against the end stop 28 in question, which in the long term could lead to damage to the opening limiter 20; Rather, the carriage 26 comes into contact with the damping unit 30, which is arranged between the carriage 26 and the end stop 28, so that the kinetic energy of the wing 12 is at least partially absorbed by the damping unit 30.

For the sake of completeness, it should be mentioned at this point that, in FIG. 2, the slide 26 has been detached from the first end of the limiting arm 24 and shifted a little in the direction of its first position in order to be easier to see. The structure of the damping unit 30 according to the invention will now be discussed in greater detail below with reference to FIGS. 4 and 5. Basically, the damping unit 30 according to the invention is not a one-piece body; Rather, the damping unit 30 consists of two different components, namely, on the one hand, a reversibly deformable damping element 32 and, on the other hand, at least one or more fold elements 34, which can be detachably or permanently connected to the damping element 32. In the damping unit 30 shown here, a total of three fold elements 34 are provided, which are connected to the damping element 32, as will be explained in more detail below.

Basically, the damping element 32 is an elongated or elongated body made of an elastic or viscoelastic plastic material, such as a foamed polymer material (e.g. Vulkollan ^® from Covestro Group or Cellasto ^® from BASF), which is used to accommodate each pleated element 34 has an indented or constricted section 50 from. These indented sections 50 have a reduced cross-section compared to the intermediate or adjoining damping sections 52, so that the individual fold elements 34 can be fitted in the area of these indented sections 50 without these elements 34 protruding laterally beyond the contour of the damping sections 52, see 4. The fold elements 34 are formed from a stiffer material than the damping element 32 and can be made of PTFE, for example.

The folding elements 34 have a substantially U-shaped connecting section 42 (see FIGS. 5 and 6), which is shaped so that its outer contour essentially corresponds to the inner contour of the guide rail 22 so that it can be guided by it, see Fig. 6. The outer contour of the U-shaped connecting section 42 is therefore complementarily matched to the inner contour of the guide rail 22 so that the holding elements 34 can slide along the guide rail 22, which is facilitated by the formation of the holding elements 34 from low-friction PTFE.

At its closed end, the U-shaped connecting section 42 of the holding elements 34 merges in one piece into a guide section 46, with two opposing receiving grooves 34 being formed in the guide section 46, into which the two flanges 36 of the guide rail 22 engage. The flanges 36 in question define between their free ends a slot 38 which extends in the longitudinal direction of the guide rail and through which the holding element 34 extends outward from the interior 40 of the guide rail 22. The guide section 46 has a width in the area of the slot 38 in question which essentially corresponds to the width of the slot 38. Because the flanges 36 of the guide rail 22 engage in the receiving grooves 44 formed on both sides of the holding elements 34 and thus engage behind the connecting section 42 as viewed from the interior 46 of the guide rail 22, the holding elements 34 and thus also the damping unit 30 as a whole are captive of the guide rail 22 th. The damping element 32 is thus held in the guide rail 22 by means of the holding elements 34 in a losable manner.

As can also be seen from FIGS. 4 to 6, when viewed in cross section, the guide section 46 has an essentially dovetail-shaped shape, which is thus based on the shape of the guide rail 22 and in particular on the shape of the two flanges 36 of the guide rail 22 it is coordinated that the two flanges 36, viewed from the interior 40 of the guide rail 22, are engaged from behind by the guide section 46. In the specifically illustrated embodiment, each of the flanges 36 of the guide rail 22 has an outer surface 48 which is inclined in such a way that the respective flange 36 tapers in the direction of its free end. Due to the dovetail shape of the guide section 46, this thus has a guide surface 54 running parallel to the outer surface 48 of the respective flange 36, which not only ensures particularly reliable guidance of the fold elements 34 along the flanges 36, but also in particular that the folding elements 34 with their Führungsab cut 46 do not protrude beyond the outer contour of the guide rail 22.

If the damping element 32 is now compressed in the longitudinal direction of the guide rail 22 as a result of an impact of the slide 26, this compression of the damping element 32 is not impaired by the holding elements 34, since the holding elements 34 can be displaced in the longitudinal direction of the guide rail 22 as a result of a compression of the damping element 32 .

Rather, when the damping element 32 is compressed, the holding elements 34 ensure that it cannot be pushed out of the interior 40 of the guide rail 22. This is prevented particularly reliably by the fact that, in the embodiment shown here, the damping element 32 is secured in the guide rail 22 by means of three retaining elements 34: The middle retaining element 34 prevents the damping element 32 from bending outwards in the middle or can bulge, whereas the other two holding elements 34, which are arranged in the vicinity of the two ends of the damping element 42, can prevent the two ends of the damping element 32 from bulging out of the interior 40 of the guide rail 22 outward when the damping unit 30 is compressed in its entirety as a result of an impact by the carriage 26.
