Description

The present invention relates to a pivot bearing for a swing-wing middle wing of a at least dreiflügligen window or door, consisting of an upper and lower bearing part, which bearing part in each case comprises a fastened to the casement rail-shaped holding part and an attachable to the frame rail-shaped support member, on which rail-shaped Carrying a bolt along a guide rail is slidably mounted, on which a bolt bearing sleeve is attached, which is attached to the outer end portion of the rail-shaped holding part, said bolt and bearing sleeve form the pivot bearing of the wing, and at the inner end portion of the rail-shaped support member, a steering lever with its one End is hinged, while the other end of the steering lever is articulated in a central region on the rail-shaped holding part, such that when you open the wing, the pivot bearing from the adjacent wing along the guideway moved away and moved when closing the wing to the adjacent wing along the guideway.

With such pivot bearings for a swing-wing middle wing, for example, a three-winged window is achieved that the middle rotary wing can be opened and closed, regardless of the opening position of the rotary bearing side arranged pivotable adjacent wing. In addition, these pivot bearings are invisible to a viewer in the closed state of the middle wing, which affects the aesthetic design of such a window.

In order to achieve a virtually airtight closure between the two adjacent wings, the window frame profiles have interlocking and overlapping areas in which seals are additionally housed. In order to achieve the best possible extension of the frame profile from the frame profile of the adjacent wing when opening the central wing, without collisions can occur, it is necessary, the pivot bearing for pivoting the middle Wing to make this pivot bearing so that it can be moved away from the adjacent wing.

Such a device is for example from the EP-A-1 234 942 known. During pivoting of the central wing about the pivot bearing these pivot bearings are moved along a guideway from the adjacent wing during the rotation of the wing, which is accessible by a handlebar, one end of the pivot bearing spaced hinged to the fitting, while the other end of the co-rotating fitting is articulated in the central region. The pivot bearing axis is in this illustrated device in a staggered towards the opening side of the wing position. During pivoting of the wing, the pivot bearing is moved along a guideway, which is aligned parallel to the frame.

This arrangement has the disadvantage that in the first Aufschwenkbereich when opening the wing between the sash and the rollover of the frame of the adjacent window, a large gap must be provided so that there is no collision when opening.

The object of the present invention is to form the pivot bearing so that an improvement of the extension of the frame profile when pivoting the middle wing from the frame profile of the adjacent window can be achieved.

According to the invention, this object is achieved in that the guide track for the bolt has a first area adjacent to the adjacent wing, which is aligned parallel to the window frame, to which first area a second area adjoins, which is inclined with respect to the first area and against the opening side of the wing away from the first area and opens into a third area, which is aligned parallel to the frame and is offset with respect to the first area towards the opening side of the wing.

As a result, in a first region, optimum extension with respect to the frame profile side, which is directed against the opening side of the wing, is achieved, while in the further pivoting region the opposite frame side can pass in an optimum manner on the window frame.

A further advantageous embodiment of the invention is that the rail-shaped support member is formed of two flat profiles laid one above the other, the flat profile located below is fitting to the frame and the guide track is formed in the overhead flat profile as a slot, and the flat profile above has a survey, which extends over the length of the slot, so that in the region of the slot between the upper flat profile and the lower flat profile a gap-shaped gap is formed, in which a slide is housed, which carries the protruding through the slot bolt. Thereby, a very simple construction of the rail-shaped support member is achieved, in particular it is advantageous that the guideway can be formed as a slot, which is open, so that the risk of contamination is very low.

Advantageously, a guide pin is mounted in the carriage, which is spaced from the bolt and which projects into the slot. As a result, the carriage can have a relatively large contact surface, the load is distributed in an optimum manner, the functioning is improved and wear of the sliding parts is reduced.

A further advantageous embodiment of the invention is that the rail-shaped holding part is formed from two superposed flat profiles, whose mutual position is adjustable via adjusting means. In addition to the simple structure of the rail-shaped holding part, the position of the window sash with respect to the window frame can be optimally adjusted in a simple manner.

Advantageously, the adjusting means are formed of two spaced-apart eccentric, the pivot each in holes of the the eccentric pins are each mounted in a slot-shaped recess, which are mounted in the underlying further flat profile, of which slot-shaped recesses aligned parallel to the longitudinal alignment and the other slot-shaped recess transversely to the longitudinal alignment of the underlying further flat profile is. Through these two eccentric pins can be adjusted by twisting the wings both in the frame plane and perpendicular thereto.

In order to adjust the height of the wing with respect to the frame, the bearing sleeve is attached to the underlying further flat profile and projecting against the overhead further flat profile, in which protruding end portion of the bearing sleeve in the through hole an internal thread is inserted, in which a screw is screwed , About this screw can be the penetration depth of the bolt set in the bearing sleeve, whereby the altitude of the wing is fixed.

A further advantageous embodiment of the invention is that the two juxtaposed further flat profiles which form the rail-shaped holding part, are releasably connected to each other via connecting means. As a result, the wing can be easily inserted and removed from the storage with mounted holding part and support member in the storage. A simple construction of this connecting means is that they are formed from a head bolt in which the lateral flanks are removed, and which head bolt is rotatably held in the overhead further flat profile, the head protrudes through a slot in the underlying further flat profile and by turning the Head bolt with respect to the slot a lock is reached. As a result, this connection can be made in the simplest way and released again.

An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings.

As can be seen from FIG. 1, the respective bearing part 1 of a pivot bearing formed from two such bearing parts 1 is composed of a rail-shaped holding part 2 and a rail-shaped supporting part 3. The holding part 2 is, as will be seen later, attached to the sash of the swing-wing, while the rail-shaped support member 3 is fixed to the frame. On the holding part 2, a bearing sleeve 4 is fixed, which is attached to a non-visible bolt, which is arranged in a carriage is, which is movable along a guide 5, which is housed in the support member 3. At the inner end portion 6 of the rail-shaped support part 3, the one end 7 of a link lever 8 is articulated. The other end 9 of the handlebar lever 8 is articulated in a central region on the rail-shaped holding part 2.

When pivoting the holding part 2 with respect to the support member 3 and the wing with respect to the frame, the holding part 2 rotates about the axis formed by the bearing sleeve 4 and the bolt, not shown, the handlebar lever causes during pivoting the bearing sleeve 4 along with the bolt the guide track 5 is moved, whereby the formed by the bearing sleeve 4 and the bolt pivot for the wing is moved.

Fig. 2 shows the bearing part 1, as shown and described in Fig. 1, in fully eingeschwenktem state, that is, the wing would be closed.

From the exploded spatial representation of FIG. 3 it can be seen that the support member 3 is formed of two superimposed flat profiles 10 and 11. These two superposed flat sections 10 and 11 are fastened together on the frame 12, for example by screwing. In the upper flat profile 11, the guide track 5 is attached, which has the shape of a slot 13. Over the entire length of this slot 13, the upper flat profile 11 has a raised portion 14, whereby in the region of the slot 13 between the upper flat profile 11 and the lower flat profile 10 below a gap-shaped gap is formed.

In this gap-shaped intermediate space, a sliding carriage 16 is accommodated, which carries a bolt 17 which projects through the slot 13 in the mounted state. The sliding carriage 16 is plate-shaped, and is provided with a guide pin 18 which is spaced from the pin 17 and which also projects into the slot 13. By the bolt 17 and the guide pin 18 of the sliding carriage 16 is guided in the slot 13 through which plate-shaped configuration of the slide 16, the support surface on the underlying flat profile 10 is relatively large, the load to be supported is well distributed, whereby excessive wear is avoided, which has an effect on the life of the bearing part.

The slot 13 acting as a guide track has a first area 19 which, as will be seen later, is adjacent to the adjacent wing, which first area 19 is aligned parallel to the window frame. A second region 20 adjoins this first region 19 and extends away from the first region 19 obliquely with respect to the first region 19 in the direction of the opening side of the vane. The second region 20 opens into a third region 21, which is aligned parallel to the frame and is offset with respect to the first region 19 against the opening side 40 (FIG. 4) of the wing.

At this overhead flat section 11 of the steering lever 8 is hinged at one end 7.

The holding part 2 is formed from two superposed flat profiles 22 and 23, whose mutual position is adjustable via adjusting means 24. The overhead further flat profile is attached to the sash 25 of the window sash 26 shown here.

On the lower flat profile 23, the bearing sleeve 4 is fixed, which is placed in the assembled state on the pin 17 of the slide 16. The bearing sleeve 4 is equipped with an internal thread into which an adjusting screw 27 can be screwed, with which the height position of the wing 26 can be adjusted, as will be explained later. In the middle region of the underlying further flat profile 23, the other end 9 of the steering lever 8 is articulated.

The adjusting means 24, with which the underlying further flat profile 23 with respect to the overhead further flat profile 22 can be adjusted, each consist of an eccentric 28, the pivot pin 29 each mounted in holes 30 of the wing frame 25 above further flat profile 22 are used and can be rotated. The eccentric 28 each project into a slot-shaped recess 31 and 32, which are mounted in the underlying further flat profile 23. The one slot-shaped recess 31 is parallel to the longitudinal alignment and the other slot-shaped recess 32 is aligned transversely to the longitudinal direction of the underlying further flat profile 23. By adjusting the eccentric 28 in the step-shaped recess 31, the pressing of the sash is set to the aperture frame 12, while with the eccentric 28 in the slot-shaped recess 32 during rotation, the vertical position of the wing 26 can be adjusted.

The underlying further flat profile 23 is detachably connected to the overhead further flat profile 22 via connecting means 33. These connecting means 33 comprise a head bolt 34, in which the lateral flanks 35 are removed. The head bolt 34 is rotatably held in the overhead further flat profile 22, the head protrudes through a slot 36 in the underlying further flat profile 23, by turning the head bolt 34 with respect to the slot 36, the underlying further flat profile 23 can be locked to the overhead further flat profile 22 , wherein the exact mutual position is achieved by the adjustment means 24.

From Fig. 4, the swing-open middle wing 26 can be seen, which is held on bearing parts 1 on the frame 12. In the illustrated here closed state of the middle wing 26 of the sash 25 is retracted into the sash 37 of the adjacent wing 38, whereby an optimal closure is achieved.

From this Fig. 4, the pivot axis 39 can be seen, which is formed from bolts 17 and bearing sleeve 4 (Fig. 3). The middle wing 26 can be pivoted about this pivot axis 39, against the opening side 40 back. As has already been mentioned, and as can be seen from FIG. 5, the pivot axis 39 shifts along the first region 19 of the slot 13, caused by the steering lever 8, during the first part of the pivoting-up of the middle wing 26. This first region 19 of the slot 13 is located on the side remote from the opening side 40 side part of the above lying flat profile 11, the sash 25 of the opening middle panel 26 moves in an optimal manner from the sash frame 37 of the adjacent wing 38 from.

As can be seen from FIG. 6, the pivot axis 39 of the swing-open central wing 26, after leaving the first region 19 of the slot 13, which in the present exemplary embodiment takes place with a wing swung through approximately 30 °, passes through the second region 20 and enters the third area 21. In this case, the pivot axis 39 shifts towards the opening side 40, so that 26 no collision with the frame 12 is formed upon complete pivoting of the pivotable central wing. As a result, an optimum course is obtained when pivoting the pivotable middle wing 26, in a first region for extension out of the sash frame 37 of the wing 38, in a further region with respect to the frame 12.

From Fig. 7, the sliding carriage 16 can be seen, on which the bolt 17 and the guide pin 18 are mounted, which are movable in the support member 3 along the slot 13. The bolt 17 protrudes into the bearing sleeve 4, which is fastened to the holding part 2. As has already been mentioned, an internal thread is mounted in this bearing sleeve 4, in which the adjusting screw 27 can be screwed. Between the end of the bolt 17 and the screwed end of the adjusting screw 27, a ball 41 can be inserted. By turning the adjusting screw 27, the height position of the bearing sleeve 4 can be adjusted to the bolt 17, which is synonymous with the setting of the holding part 2 and thus of the sash with respect to the support member 3 and consequently of the frame 12. The ball 41 serves to ensure that no large frictional forces occur during pivoting of the wing, the storage is thus optimized.

The view from above on the bearing part 1, as shown in Fig. 8, shows the pivoted-middle wing 26, the adjacent wing 28, and connected to the frame, not shown supporting part 3 and the pivotable on the central wing 26 holding part. 2 In this view, the eccentric 28 can be seen, which in the two slit-shaped recesses 31 and 32 protrude, and through which the swinging central wing 26 is adjustable.

With this inventive pivot bearing an optimal pivoting of a central pivotable wing is achieved, in particular with regard to the extension from the adjacent wing. Here, this pivot bearing has a simple structure, with which an optimal adjustment of the swing-open central wing is reached, also the swing-wing is in the simplest way from the top and bottom mounted bearing part to dismantle and reinstate.

The pairwise usable bearing parts for one-sided upper and lower mounting of the swing-up middle wing can be used for left and right swinging wings, by being able to be replaced diagonally. Consequently, these bearing parts must be made only in pairs, each pair can be used for swinging left and right wings, whereby the bearing support and a possible confusion is excluded.
