EP2811092B1 - Door or window with a pivoting fitting - Google Patents

Description

The present invention relates to a door or a window with a frame and a wing, which in the lower corner opposite the frame by means of a closed wing closed swivel fitting can be pivoted by at least 90 °, according to the preamble of claim 1.

The DE 27 51 682 discloses an opening device for a door or a window with a pivot fitting with the features of the preamble of claim 1. The pivot fitting comprises a multi-link arrangement, by means of which a wing is held pivotable relative to the frame.

A door or a window with another swing fitting is out of the DE 10 2009 043 665 A1 known. In the swivel fitting described there, the support member is designed as a support rail of the multi-link arrangement, which is connected to the support arm via a rotation axis, which in turn is displaceably guided relative to the support rail. In this case, the pivot point between the support arm and the support member is closer to the stationary axis of rotation than the axis of rotation, which is displaceable relative to the support rail.

Other components of the multi-link arrangement are a control arm and a rotary arm. Except for the displaceable axis of rotation, all other components of the multi-link arrangement are exclusively rotatably connected or mounted.

Such a construction is impeccable with respect to its handlebar function and has also proven itself in practice, but the overall construction is relatively large. Due to the displaceable arrangement of the axis of rotation between the carrier rail and the support arm, it is possible, especially when used in areas prone to contamination, to impair the smooth running of the swivel fitting.

The present invention has for its object to further develop a window or door of the generic type such that the swivel fitting is largely störungsunanfällig in a small and compact design in rough everyday operation.

This object is achieved by a door or a window with the features of claim 1.

The multi-link arrangement has a support member which is pivotally connected on the one hand on the wing and on the other hand pivotable about a pivot point on the support arm and that the fulcrum between support arm and support member during the entire opening movement is further away from the stationary axis of rotation than the pivot point between the wing and the supporting part.

By this structural design of the swivel fitting a compact design compared to the prior art is achieved while reducing the susceptibility in continuous operation, since the multi-link arrangement of the swivel fitting exclusively relative to each other has rotatably interconnected components.

According to the invention, it is provided that the wing is pivotable relative to the frame by at least 90 ° and by up to 180 °.

A further development of the invention provides that the carrier part is fixed length-displaceably within limits on a base rail fixable base rail.

Preferably, according to a further embodiment of the invention, the support member and base rail are made of metal and the base rail has at least two openings, which are each pass from a punched out of the support member and angled guide web, each guide web in its over the base rail also protruding head is provided with anchor webs, which engage behind the surrounding area of the respective opening of the base rail.

Such a connection between the carrier part and the base rail is to be realized in that the openings are widened prior to insertion of the guide webs such that the anchor webs can be inserted through the widened openings and then that the base rail is pressed so far in the region of the openings again so far that the guide webs can not be pulled out of the base rail again.

According to a further embodiment of the invention, it is provided that the carrier part is provided with a transverse to the longitudinal direction of the base rail extending slot, within which an eccentrically arranged head of a rotatably mounted in the base rail adjusting element is arranged.

Further features of the invention are the subject of further subclaims.

Embodiments of the invention are illustrated in the accompanying drawings and will be described in more detail below.

In the FIGS. 1 and 2 a corner region of a door or a window 1 is shown, wherein the reference numeral 2 denotes a frame and the reference numeral 3 denotes a wing, which in the illustrated lower corner region relative to the frame 2 by means of a pivot fitting 4 is pivotable.

The swivel fitting 4 is installed concealed in a conventional manner, ie, that the pivot fitting 4 is not visible from the outside when the wing 3 is closed. The swivel fitting 4 allows pivoting of the wing 3 relative to the frame 2 by at least 90 °, and up to 180 °, as in the FIGS. 1 and 2 is shown.

The swivel fitting 4, in the FIGS. 3 to 6 is shown in detail, comprises a fixable on the frame 2 carrier part 5, on which a multi-link arrangement 6 is pivotally mounted on a relative to the frame 2 fixed axis of rotation 7.

Furthermore, the multi-link arrangement 6 on a support arm 8 which is pivotally mounted on the axis of rotation 7.

Further components of the multi-link arrangement 6 are a control arm 19 and a rotary arm 20.

The wing 3 is arranged on or on a support rail 9 of the multi-link arrangement 6, wherein the support rail 9 is connected to the wing 3 and as far as part of this wing 3.

Furthermore, the multi-linkage arrangement 6 has a supporting part 10, which is articulated on the one hand on the wing (here on the mounting rail 9) and on the other hand is connected pivotally to the mounting rail 9 only about a pivot point 11. In this case, the pivot point 11 between the support arm 8 and support member 10 is further away from the axis of rotation 7 than the pivot point 12 between the wing 3 and the support member 10th

As a result, a total of a compact structural design of the swivel fitting 4 is achieved, also all parts of the multi-link arrangement of the swivel fitting 4 are exclusively rotatably connected to each other, whereby the susceptibility is significantly reduced even in continuous operation and under harsh environmental conditions.

It has already been mentioned that the carrier part 5 is connected to the frame 2. The connection is made via a base rail 13, which in turn is fixable in a receiving groove of the frame 2 and with the carrier part 5 is connected longitudinally displaceable for adjustment within certain limits.

As the FIGS. 7a, 7b, 8 . 9, 10 and 11 show, the base rail 13 a plurality of apertures 14. This is off Figure 7a very clearly visible.

The support member 5 is provided with a corresponding number of guide webs 15 which are punched out of the support member 5 and angled. These guide webs 15 pass through the apertures 14 of the base rail 13 in the mounted state and have anchor webs 15a in their head region, which engage behind the surrounding area of the respective opening 14 of the base rail 13. Thus, the base rail 13 and support member 5 are indeed insoluble, but in the longitudinal direction relative to each other slidably connected. Since the base rail 13 in turn fixed in frame 2 fixed, the support member 5 and thus the wing 3 can be moved for adjustment relative to the frame 2 in limits.

In order to pass through the anchor bars 15a through the openings 14 of the base rail 13, they must, as Figure 7a shows widened before mounting. After passing through the anchor webs 15a ( Fig. 10 ) the expanded area of the openings 14 is compressed again ( Fig. 11 ), so that the lateral boundaries of the apertures 14 abut the guide webs 15 practically frictionally. As a result, on the one hand good guidance and on the other hand a secure connection between the base rail 13 and support member 5 is achieved.

Both the base rail 13 as well as the support member 5 are made of metal to accommodate the loads occurring safely. In order to easily perform a displacement of the support member 5 relative to the base rail 13, an eccentric solution is provided. Here, the support member 5 has a transverse to its longitudinal direction and also transversely to the longitudinal direction of the base rail 13 extending slot 16, within which an eccentrically arranged head 17 of a rotatably mounted in the base rail 13 adjusting element is arranged. Thus, with the help of a simple Tool, such as a screwdriver, an adjustment by turning the head 17 can be brought about.

The determination of the base rail 13 on the frame 2 is carried out in a known manner by anchor stones 18, which are rotatably arranged relative to the base rail 13 and allow a tension within a correspondingly sized C-shaped groove of the frame 2.

In the Figures 12-14 an embodiment of a swivel fitting 4 is shown, which differs from the embodiments described and described so far in that an opening angle limiting device 21 is provided, by means of which the per se possible maximum opening angle of 180 ° can be reduced, for example to 90 °.

Such an embodiment makes sense, as this opens up the possibility to realize a variety of applications of the swivel fitting 4 cost.

Thus, it is no longer necessary to produce different swivel fittings for doors or windows with opening angles deviating from 180 ° opening angle, but, starting from a basic conception with 180 ° opening angle, by attaching an opening angle limiting device 21 to achieve a lower maximum opening angle, whereby the manufacturing and storage costs can be significantly reduced overall.

As a preferred embodiment according to the Figures 12-14 shows, the opening angle limiting device 21 essentially consists of a link 22, which is connected on the one hand hinged frame side on the support member 5 and on the other hand guided via a slider 23 in a groove of the sash 3. The slider 23 is in alignment with the support rail 9 of the swivel fitting 4, wherein the support rail 9 to some extent forms a stop for the slider 23.

Of course, here also a kinematic reversal can be made such that the link 22 is articulated on the casement and the slider 23 is guided in a groove of the frame and the support member 5 is formed as a stop for the slider 23.

The slider 23 can in the frame groove on the one hand good sliding and in the contact region of the swivel fitting, so when reaching the desired window opening, energy-consuming, so braking, or even be performed detent. For this purpose, both different materials, such as e.g. Elastomers and their combinations, e.g. Metal / plastic compounds, as well as constructive measures such. Clamping springs, friction elements, buffer elements, braking latching elements are used.

The slider 23 is made for example of a plastic with a certain elasticity, so that there is a damping effect, upon impact of the slider 23 on a fixed element which forms a stop for the slider 23 results

A possible embodiment provides that the slider 23 with its elasticity achieves a damping effect, which results when hitting the front end of the support rail 9.

A particularly homogeneous damping curve occurs when the slider 23 when hitting a catch 25 of a stop member 24 has a receptacle 26 which has a brake opening which defines a braking distance over its resiliently deformable region. In this case, for example, by one or more resilient openings 27 (see Fig. 13 ) depending on the geometric design of these openings 27 different damping, Verrastungs- and braking properties reached. This is a great advantage, since in this case the outer contour of the slider 23 remains unchanged and thus can be adapted to the intended use.

It is preferably provided that the slider 23 opposite the front end of the support rail 9 has a stop member 24 which is provided with a slider 23 facing the latch 25 and inserted into a resilient receptacle 26 of the slider 23.

A particularly good damping / braking behavior results when the stop member 24 is embedded with the catch 25 in a pocket, so that there is at least one additional contact surface on the stop member 24. Here, the advantage lies in using the low manufacturing tolerances of fitting part production and the wear resistance of the friction partners used here for a defined braking / locking behavior. So it does not have to be on the Manufacturing tolerances of frame profiles are used, which thus show an inaccurate Abbrems- / Verrastungsverhalten or abrade their color coatings prematurely and are unsightly.

In a possible embodiment, the brake opening is at least in the region of a prong 28 of the receptacle 26 (FIG. Figure 13 ) during their movement in the direction of the end position ( Fig. 14 ) deformed by the locking member 25 when passing. It comes for the brake opening between the detent 25 and contact surface on the pocket wall to a deformation or pressure and thus friction, so a stronger, but gentler braking force. The desired braking effect can therefore be defined and controlled over a certain distance.

It is possible to hollow out the brake port, or with other solid, liquid, gaseous, or porous materials or structural elements, e.g. To provide springs or capsules for use adaptation.

A braking effect is achieved with a continuous braking distance between 5 - 50 mm, with the practical area with a good braking effect between 7 - 30 mm and the particularly homogeneous braking range is between 10 - 25 mm.

As a result of this construction, when the maximum opening angle predetermined by the opening angle limiting device 21 is attained, damping of the stop movement as well as fixation of the opened wing 3, which can be easily overcome, however, by applying corresponding closing forces.

In FIG. 13 the state of the swivel fitting 4 is shown, in which the slider 23 is located shortly before hitting the support rail 9. In Figure 14 it is shown that the stop member 24 is retracted with its catch 25 in the receptacle 26 of the resilient slider 23.

In FIG. 15 an embodiment of the invention is shown, which in its basic function of the embodiment of the Figures 12-14 equivalent.

Deviating is here only that the link 22 of the opening angle limiting device 21 is variable in length.

It is in the illustrated embodiment according to FIG. 15 a stepwise extension or shortening of the link 22 possible through various holes 21a through which inserted after setting the specific or desired length corresponding fasteners and the two halves of the arm 22 can be firmly connected to each other.

Deviating from this, of course, a stepless or telescopic length change is possible, in which case the advantage is achieved that not only different opening angles are adjustable, but also a fine adjustment can be made.
