EP0045009B1 - Wing for a window, door or the like that can be put in a pivoting or in a parallel position at wish - Google Patents

Abstract

A mounting is disclosed for the movable member of a window or door in a fixed frame which comprises four set-off arms connected to corners of the movable member. Each set-off arm is pivoted and slidably mounted to the movable member at one end thereof and pivotally mounted to the frame in an opposite end thereof. An auxiliary arm is pivotally mounted to the set-off arm at an intermediate location thereon and also to the movable member. The set-off arms take up opposite mirror image inclined positions with the movable member in its closed and opened position respectively. The upper set-off arms are mirror images of the lower set-off arms about a plane perpendicular to the plane of the movable member with the pivotal and sliding engagement between upper and lower set-off arms being closer to each other than the pivotal engagement between those set-off arms and their associated auxiliary arms.

Description

The invention relates to an optionally tiltable or parallel sash of a window, a door or the like, which is held via an upper and lower, on the vertical spar of the sash and on the associated fixed frame each pivot arm. To tilt the sash, only the upper left and right extension arms are extended, while the lower extension arms maintain their position opposite the sash. To park the sash in parallel, raise all four extension arms. This previously known window is a vertical sliding window, the sash weight of which is primarily taken up by ropes. However, this construction is not suitable for sashes that are not held by ropes because they can only be adjusted with great effort and the load on the extension arms and the force dissipation would be unfavorable.

Windows of the type mentioned at the outset are also known, in which an adjustable extension arm is arranged on the lower end face of the vertical wing spars (FR-A-2 321 030).

The object of the invention is to provide a wing with a fixed frame of the type mentioned, which can be adjusted in particular even with a high wing weight without great effort and in which the occurring forces are derived favorably.

To achieve this object, it is proposed according to the invention that the wing is designed with an associated fixed frame according to the preamble of claim 1 in accordance with the characterizing part of this claim. If the usual dimension of parallel parking is used, the extension arm and auxiliary arm can be dimensioned and attached in such a way that their longitudinal axes are only slightly inclined in relation to the sash level, both in the closed position and in the parallel storage position to the sash level, and this applies accordingly to the upper one Extension arms also in the tilted position. This results in a very favorable transfer of force from the sash weight to the frame, and this leads to an unproblematic loading of these parts even with high sash weights. In addition, the center of gravity of the wing is moved on a horizontal line when it is parked in parallel and also when it is returned from the parallel storage position, and consequently only a minimal effort is required. A further decisive advantage is seen in the fact that the scissors consisting of the extension arm and auxiliary arm can be used equally for the lower and for the upper wing corner. This leads to an expansion of the series and thus contributes to cost-effective production. Tilting, parallel parking and returning the sash to the closed position can either be done manually or with positive control using an appropriate device.

In a further development of the invention, it is proposed that the extension arms are supported on the fixed frame by means of rolling or sliding elements, and these are located in particular on the frame-side end of their extension arm. If the sash is to be moved in the parallel storage position, for example along a second sash, which can be designed as a fixed sash, then one will expediently attach rolling elements, for example rollers or pairs of rollers, to the two lower extension arms, while sliding elements for the upper extension arms can provide in the form of a sliding shoe or the like.

In this case, the rollers would work together with corresponding running rails, while a sliding rail adapted to their shape can be used for the sliding elements. As a result, a preferred embodiment of the invention provides that the lower extension arms are supported on at least one roller, but preferably a pair of rollers, on a running rail or the like. The roller or rollers are mounted on a roller holder, on which the frame-side end the arm is articulated. The rollers or pairs of rollers therefore remain in any possible position of the wing on or in their running rail, and when the wing is tilted or placed in parallel, the extension arm is pivoted relative to the roller holder. Analogously, a sliding element holder is of course also provided on the upper extension arm, with respect to which the upper extension arm can be pivoted. Otherwise, due to the lateral arrangement of the raising and auxiliary arms, the pivoting plane of these arms runs perpendicular to the wing plane.

According to a further variant of the invention, it is provided that the two roller holders of the lower extension arms are connected to one another by means of a rod-shaped or tubular member, which is in particular pluggable. For this purpose, a spike-like extension can be provided on the roll holder, on which the extension member is attached to the other roll holder.

In a particularly preferred manner, it is provided that on each horizontal spar of the wing there is a control pin, which is assigned to each extension arm and can be actuated by means of a drive rod, and which forms a control device for adjusting the wing with the transmission members rotatably mounted on this spar, the upper and move the lower control pin while simultaneously moving in opposite directions, and that the upper control pin can be moved without the lower, but not the lower without the upper. If, for example, the control pin of the lower left wing corner moves from right to left, there is also a movement of the top left control pin from left to right. This makes it possible to use one and the same fitting element comprising the above-mentioned components for the lower left and the upper right corner, but the upper part is upside down relative to the lower part. Two identical fitting elements are also used for the upper left and lower right corners, but these are right-hand versions if the former are called left-hand versions. If all four control pins are moved at the same time, ie the lower two, for example, from right to left and the upper two from left to right, this leads to a parallel parking of the wing. Counter-rotating pin movements naturally cause the wing to close. If, on the other hand, you only switch the upper control pins, only the upper wing end moves outwards and you reach the tilt position. In this context, it is particularly expedient that the drive rod of the lower control pin is connected to the drive rod of the upper control pin via a coupling device. This coupling device can be of relatively simple construction and in particular can be operated by hand.

In a further embodiment of the invention, it is proposed that the peg engage in an arcuate control slot of a first rotary member, which interacts with a second rotary member in the manner of a toggle lever, both rotary members being mounted on the horizontal wing spar and in one perpendicular to the wing plane and to the pivot plane of the associated raising arm are pivotable, and that the second rotary member is rotatably connected to a control rod, one end of which is pivotally and slidably mounted on the horizontal wing spar and the other end of which is rotatably mounted on the raising arm. The pivoting plane of the latter then runs parallel to that of the rotating members. The control pin connected to a push rod performs a linear movement along the lower or upper horizontal wing spar in a known manner. The arc shape of the control slot is selected so that the wing can be pivoted from the closed position into the parallel storage position or tilting position and vice versa when the control pin is at maximum stroke. In a further development of the invention, the control rod is mounted on the extension arm via a ball joint.

Another preferred variant of the invention provides that the control rod, the first and the second rotary member are mounted on one leg of a corner bracket for the wing corner, on the other angle leg of which the pivoting arm and the auxiliary arm are articulated. This design has the advantage that all parts required for the controlled display and return of the wing can be preassembled and attached as a structural unit to the wing or the wing corner. It is particularly advantageous here if the corner bracket is part of a corner deflection for the drive rod, so that after mounting these four corner brackets there are at most drive rod extensions and the actuating device with the coupling device.

In order to be able to cope with the forces that occur with very heavy sashes, it is particularly advantageous if the first and second rotary members are coupled to one another via a toothing or a similar device.

In the drawing, an embodiment of the invention is shown. Show it:

• 1 is a front view of a window, the left wing of which can be tilted, set down in parallel and displaced,
• FIG. 2 shows the same view with the wing tilted,
• FIG. 3 also a front view with the wing placed parallel,
• Figures 4 u. 6 side views of FIGS. 1,2,3,
• FIG. 7 the fitting of the lower left wing corner in a top view, partly broken away,
• 8 is a view of FIG. 7 in the direction of arrow A,
• 9 is a view of FIG. 7 in the direction of arrow B.

The window comprises a fixed field 1, a movable wing 2 and a fixed frame 3. The movable wing 2 is held at each of its four corners by means of a stay scissor 4 on the fixed frame 3, which has a stay arm 5 and an auxiliary arm 6. The upper scissors are mirror images of the lower ones, as shown in FIG. 6. If you only open the upper stay scissors, the wing takes up its tilt position (Fig. 5), while when you open all four stays the wing assumes its parallel storage position, in which it can be moved along the fixed field 1. Switching takes place with the aid of a gear 7 with a hand lever 8 and an additional switching device with an actuator 9.

Fig. 9 shows the wing 2 with solid lines in the closed position with dash-dotted lines in the parallel storage position. The same applies to FIG. 8. One end 10 of the raising arm 5 is rotatable on the wing and is displaceably mounted in the direction of the double arrow 11, while its other end 12 is held on the fixed frame 3 so that it can pivot about an axis 13. A bearing pin 14 of one end 10 engages in a longitudinal slot 15 of one leg 16 of a corner bracket 17. The latter belongs to a so-called corner deflection 18 for a drive rod 19, the other leg of which is designated 20 (FIG. 7).

The extension arm 5 and the auxiliary arm 6 are connected to one another in an articulated manner via an axis 21. The end of the auxiliary arm 6 facing away from the extension arm is rotatable by means of a further axis 22 on the movable wing 2, more precisely ge says, on which mounted on the relevant corner of the movable wing one leg 16 of the corner drive 18. The auxiliary arm 6 is located between the extension arm 5 and the one angle leg 16. Accordingly, there are two extension scissors 4 between the left and right pair of vertical bars of the fixed frame and the movable wing.

The bearing axis 13 for the other end 12 of the extension arm 5 is held in a roller holder 23, which carries a roller 24 and 25 on the left and right, which are supported on a rail 26 of the fixed frame 3. In order to prevent the extension arms 5 from bending under the influence of the inertia forces occurring during the displacement, an extension member (not shown) is attached to an arm 27 of the roller holder 23, which extends to the arm 27 of the roller holder 23 of the lower right wing corner and establishes the connection therewith. In a manner not shown in detail, the raising arm 6 of each upper stay scissors carries a slide shoe holder 28 for longitudinally displaceable engagement in a slide rail 29. The two slide shoe holders, like the roller holder 23, can also be connected to one another. This is the only difference, apart from the right and left education, between the hardware education at the lower and upper corner. As a result, you can use the same fitting on the upper corner as on the lower corner and only mount it in mirror image. For parallel parking, however, it is necessary that the lower drive rod 19 moves in the direction of arrow 30 and the upper drive rod parallel to it moves against arrow 30. In this case, the connecting drive rod of the left vertical wing spar moves from bottom to top, i.e. in the direction of arrow 31. Precise parallel parking requires that the stay scissors 4 assume a mirror-image position in the parallel parking position compared to their position when the wing is closed, such as this Fig. 9 shows.

The drive rod 19, in whose pin 32 an extension rod leading to the lower right corner deflection is suspended, carries a control pin 33 (FIG. 8). This engages in a control slot 34 of a first rotary member 35 rotatably mounted on the outside of the corner bracket 20. The axis of rotation of the first rotary member 35 is denoted by 36. A second rotary member 38 is pivotally mounted on this angle leg 20 about a further axis of rotation 37, the first rotary member being somewhat closer to the angle leg than the second. They are coupled to one another via a toothing 39 and act on a control rod 40 in the manner of a knee joint. The toothing consists, for example, of teeth 41 of the first rotary member 35 and rollers 42 or bolts of the second rotary member 38 acting as counter teeth. The two relative end positions of the first and second rotary members result from FIG. 8 with fixed lines on the one hand and dash-dotted lines on the other hand. The illustration with the solid lines corresponds to the closed position according to FIG. 9, while the parallel parking position is shown with dash-dotted lines. It also corresponds to the tilt position for the upper wing end.

The control rod 40 is connected to the second rotary member 38 and thus indirectly also to the first rotary member 35 with the aid of an axis of rotation 43. Its right end in FIG. 8 is rotatable and slidable in an elongated hole 44 of the angled leg 20. For this purpose it carries a bearing pin 45. The left end, however, engages in a receptacle of the extension arm 5, not shown in any more detail, which is located approximately in the middle between the axes 13 and 21. In particular, a gimbal 50, e.g. in the form of a ball joint.

The control rod 40 is designed as a straight rod, with bearing elements arranged at its two ends as described above, and with the axis of rotation 43 located approximately in the middle. The second rotary member 38 has essentially the shape of an acute, isosceles triangle, at the corners of which, according to FIG Fig. 8 are the gear rollers 42 and the axes of rotation 37 and 43. In the closed position of the wing, its axis of symmetry extends approximately in the longitudinal direction of the angle leg 20 of the corner deflection. As shown in FIG. 8, the arcuate control slot 34 of the rotary member 35 has only a relatively weak curvature, and its length roughly corresponds to three times the diameter of the control pin 33.

If the drive rod 19 is displaced in the direction of the arrow 30, the first rotary member 35 is rotated about its axis 36 in the direction of the arrow 47. The first rotary member acts in a rotating sense on the second rotary member 38, which moves in the direction of the arrow 48 rotates about its axis of rotation 37, ie the toggle lever consisting of the two parts collapses. At the same time, the second rotary member 38 causes a relative rotary movement of the control rod 40 in the direction of arrow 49 around the rotary bearing 50 on the raising arm 5, which is pivoted together with the latter about the axis 13. The wing is adjusted in the direction of arrow 51 via the bearing pin 45. The wing is returned in the opposite direction by moving the drive rods in the opposite direction of arrow 30. It remains to be added that the control pin 33 passes through a guide slot 52 of the angled leg 20. In a manner not shown, the vertical drive rod, which can be displaced with the aid of the hand lever 8, is subdivided on the locking side of the movable wing 2, and these two parts can be coupled or uncoupled from one another with the aid of a coupling device (not shown in more detail). The coupling is done by rotating the actuator 9, preferably 90 degrees. Accordingly, the lower drive rod 19 can only be displaced if the clutch has been previously engaged with the aid of the actuating member 9. In contrast to the upper vertical drive rod is constantly coupled to the transmission 7.

With the exception of the corner bracket 17, all parts for the left and right versions are identical, but are partially installed rotated by 180 °, such as the rotating member 35.
