EP0045009A1 - 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-adjustable wing of a window, a door or the like, which is held via an upper and lower, each on the vertical spar of the wing and the associated fixed frame 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. For parallel parking of the sash you put out 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.

The object of the invention is therefore 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 forces occurring are derived favorably.

To solve this task is proposed according to the invention that the wing with associated fixed frame is designed according to the preamble of claim 1 according to the characterizing part of this claim. If one takes the usual dimension of parallel parking as a basis, the extension arm and the auxiliary arm can be dimensioned and attached so that their longitudinal axes have only a slight inclination with respect 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 arms also in the tilted position. Thereby achieved a very favorable force transmission of 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 virtually on a horizontal line when parallel parking and also when returning from the parallel parking position, and consequently only a minimal effort is required for this. Another decisive advantage is seen in the fact that you can use the scissors consisting of extension arm and auxiliary arm equally for the lower as 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 be done either 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, rolling elements, for example rollers or pairs of rollers, are expediently attached to the two lower extension arms, while sliding elements are used 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 could 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 being 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, of course, a sliding element holder is 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 extension 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, in particular a plug-in type. For this purpose, a spike-like extension can be provided on the reel seat, on which the extension member is attached to the other reel seat.

In a particularly preferred manner it is provided that on each horizontal spar of the wing there is a control pin assigned to each extension arm, which can be actuated by means of a drive rod and which forms a control device for the adjustment of the wing with transfer members rotatably mounted on this spar, the upper and move the lower control pin while 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, the upper left control pin also moves from left to right. This makes it possible to use one and the same fitting element for the lower left and the upper right corner, but the upper part is upside down compared to the lower one. Two identical fitting elements are used for the upper left and lower right corner , however, these are right-wing versions if the former are referred to as 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. Opposing 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 thereby 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 control pin engages in an arcuate control slot of a first rotary member, which cooperates 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 plane, 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 pivot 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 chosen so that the wing can be pivoted from the closed position into the parallel storage position or tilting position and vice versa at maximum stroke of the control pin. The control rod is in a development of the invention via a ball joint on the extension arm stored.

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 angle for the wing corner, on the other angle leg of which the raising arm and the auxiliary arm are articulated. This training has the advantage that you can pre-assemble all the parts required for the controlled display and return of the wing. And can be 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 drive 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:

• Figure 1 is a front view of a window, the left wing tiltable, parallel can be switched off and moved,

• 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 scissor stay 4 on the fixed frame 3, which has a raising 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 its Tilt position on (Fig. 5), while when all four scissors the wing is in 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 hand lever 8 and an additional switching device with an actuator _. board 9.

Fig. 9 shows the wing 2 with fixed lines in the closed position and 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 rotatably mounted on the movable wing 2 by means of a further axis 22, more precisely, on the leg 16 of the corner deflector 18 mounted on the relevant corner of the movable wing. The auxiliary arm 6 is located between the extension arm 5 and one Angle leg 16. Accordingly, there are two stay scissors 4 between the left and right vertical spar pair 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 action 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 scissor stay 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. Apart from the right and left hand training, this is the only difference between the fitting training at the lower and upper corners. 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 moves Connecting drive rod of the left vertical wing spar from bottom to top, thus in the direction of arrow 31. Precise parallel parking assumes that the stay scissors 4 in the parallel parking position assume a mirror image position with respect to their position with the wing closed, as shown in FIG. 9.

ist. Sie entspricht auch der Kipplage für das obere Flügelende.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 storage position with dash-dotted lines

is. 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 by means 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 is aligned 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 arrow 30, this causes the first rotary member 35 to rotate about it Axis 36 in the sense of arrow 47. The first rotating member acts in a rotating sense on the second rotating member 38, which rotates in the direction of arrow 48 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 about 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 return of the wing takes place 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 angle 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 closure side of the movable wing 2, and these two parts can be uncoupled or uncoupled from one another with the aid of a coupling device, not shown. The coupling is carried out 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, 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.
