Abstract

Hardware for the closure of a door or window which is constructionally simple and functionally reliable, permitting movement of the closure out of the frame to a parallel position and allowing horizontal shifting in this position. Lower supporting arms are pivotally mounted on the closure and two traveling carriages are associated with the supporting arms and with an associated bearing block at the side of the closure. The carriages are designed in mirror-image relationship, so that the carriages are movable in opposite directions by means of a differential coupling gear.

Description

The invention relates to an opening device for an at least parallel and horizontally displaceable flights of a window, a door or the like. With lower support arms and upper extension arms, in which at least the or the lower support arms on the one hand on the lower cross member in a bearing block and on the other hand each a carriage is rotatably mounted, with a releasable locking device for at least one of the lower support arms located in the parallel storage position, which can be brought into and out of locking engagement by the sliding-closing movement of the wing relative to the support arm.

Fittings of the generic type have already been disclosed in US Pat. No. 2,741,807 and also in French Pat. No. 1,551,381. Their advantage is that they are robust in use with a structurally simple design and can therefore also be used where heavy sashes are to be brought into a parallel storage position relative to the fixed frame and then to be moved horizontally.

The construction principles of these known fittings are of such a type that each of them from their closed position relative to the fixed frame on the one hand to the right and on the other hand to the left in the opening direction horizontally movable sash two differently designed fittings must be manufactured and kept in stock.

This also applies to the fitting design, as has become known from DE-OS 32 34 677.

In the display devices according to US Pat. No. 2,741,807 and FR Pat. No. 1,551,381, the releasable locking device is formed by a support lever which must cooperate with a frame-side or fixed poaching bearing over the entire length of the horizontal displacement path for the wing. if the parallel parking position of the extension arms should be fixed in any possible sliding position.

When fitting according to DE-OS 32 34 677, on the other hand, the locking device which fixes the parallel storage position of the opening arm between the opening arm and the carriage supporting it is effective in such a way that it only in and in the area of the sliding-closing movement of the wing with a frame-mounted actuator out of operative connection.

The invention has for its object to provide an opening device of the type specified in the preamble of claim 1, which can be used in one and the same design, regardless of whether the wing relative to the fixed frame from the closed position to the right or to the right to be shifted horizontally on the left in the opening direction.

This aim is achieved according to the invention with the characterizing features of claim 1, namely by two carriages which are mirror images of one another with their support arm and the associated wing-side bearing block, which can be connected to one another in opposite directions via a differential coupling gear.

In particular, a design for the opening device has proven itself, in which the bearing axes of the support arms in the two bearing blocks attached to the sash are at a greater distance from one another in the direction of the sash plane, both in the closed position and in the parallel storage position of the sash, than the bearing axes for the latter Support arms in their trolleys. In this case, the two support arms of the opening device work together via the differential coupling gear as a positively controlled trapezoidal link system, which, with the largest possible span for the wing placed in the parallel storage position, enables space-saving accommodation of the carriage underneath the lower wing cross member.

However, it is also conceivable to provide the trapezoidal link system of the opening device between the carriage and the wing in such a way that the wing-side bearing axles of the support arms have a smaller distance from one another in the direction of the wing plane than their bearing axles on the two carriages.

According to a further development feature of the invention, claim 2 proposes that each carriage carries a thrust piece on which a link which is connected to the support arm in an articulated manner also acts in an articulated manner, the thrust path of the thrust piece and the handlebar relative to the carriage of the swivel arc height of the end engaging on the wing of the support arm around its bearing axis on the carriage.

From DE-AS 10 43 866 is known - also for parallel-adjustable sashes of windows, doors or the like. - An opening device with two mutually mirror-image extending arms and a respective attacking and the fixed frame handlebar known with a positive control by a coupling gear works. In this case, however, the swivel arm on the extension arm is only accessible Fenden handlebar is also only pivotally articulated on the fixed frame, while the ends of the extension arms facing the fixed frame there slidably move in opposite directions and are mutually controlled by the coupling gear. However, this known design is not suitable as a lower, supporting opening device for sashes of windows, doors or the like which can be horizontally displaced by means of carriages in the parallel storage position, because their opening arms cannot be used as support arms which could deposit the sash weight in the carriage.

So that the adjustment of the opening device to different widths of the wings is facilitated, claim 3 according to the invention provides that the thrust pieces of both carriages can be coupled together by a cut-to-length intermediate piece.

To achieve the object on which the invention is based, it is further essential according to claim 4 that a locking device for the opening position of the support arm is installed between each carriage and the support arm mounted thereon, and that each locking device can be blocked relative to the carriage in its ineffective position. This measure also makes it possible to block the support arm on the right or on the left carriage for the horizontal displacement of the sash located in the parallel storage position in an amazingly simple manner, as required. It is particularly recommended if, according to claim 5, the locking device assigned to the carriage advancing in the sliding-closing direction of the wing can be positively controlled relative to the support arm between its ineffective position and its locking position by means of an actuator installed in the frame, whereby it can be controlled by the start of the movement of the carriage in the opening and sliding direction from its ineffective position to the blocking position and by the termination of the travel movement of the carriage in the closing and sliding direction from its blocking position to the ineffective position.

In the simplest case, according to the invention, the locking device can consist of a vertical plane on the carriage which is pivotably mounted, two-armed latch, one lever arm of which interacts with the end of the support arm on the carriage side, while the other lever arm is assigned to the frame-side actuating element as a control element.

Of course, it would also be conceivable to give the locking device a training as it is shown, described and claimed in the earlier patent application P 36 38 456.2.

1 to 6 of the drawing, a balcony or terrace door is shown, which has a fixedly mounted wing 2 or a fixed door panel 2 in a fixed frame 1 and which is also equipped with a movable wing 3.

The movable wing 3 can be brought relative to the fixed frame 1 and to the fixed wing or door panel 2 from the closed position indicated in FIGS. 1 and 2 either in the tilt-open position, as can be seen in FIGS. 3 and 4. However, it can also be brought into a parallel position relative to the fixed frame 1 and the fixedly mounted sash or fixed door panel 2 and then in the horizontal direction in front of the permanently installed sash or the fixed door panel 2 from the area of the passage opening 4 of the fixed frame 1 move, as can be seen in FIGS. 5 and 6.

In order to enable these three positions of the sash 3 relative to the fixed frame 1 and to the fixedly mounted sash or to the fixed door panel 2, a special fitting arrangement, namely a so-called tilting parallel sliding fitting, is provided between the sash 3 and the fixed frame 1, of the or that in FIGS. 1 to 6 of For the sake of simplicity, only the operating handle 5 on the wing 3 and the upper opening device 6 and the lower opening device 7 between the door 3 and the fixed frame 1 can be seen.

In terms of kinematics, the upper opening device 6 and the lower opening device 7 can be designed similarly. The basic structure of the upper opening device 6 can, however, also be derived from types such as those e.g. U.S. Patent 4,384,429 are known to be known.

The lower opening device 7 must in any case be designed so that it bears the weight of the movable wing 3 securely while cooperating with a running rail 9 on the lower cross member of the fixed frame 1.

In the present case, the main issue is the design and mode of operation of the lower opening device 7, which is shown in FIGS. 7 and 8 in its basic structure and in each case in a basic plan view, while FIG. 9 shows the opening device 7 in a three-dimensional view.

The opening device 7 has two support arms 10, each of which is articulated on a carriage 12 so as to be pivotable about an axis 11 on a substantially horizontal plane. Each carriage 12 is provided, for example, with two rollers 13 which are freely rotatable about substantially horizontal axes and by means of which it is supported on the running rail 9 of the fixed frame 1 so as to be movable parallel to its plane.

The other end of the support arms 10 only pivotably engage the lower edge of the movable wing 3 via an axis 14.

In the area of each of the two lower corners of the wing 3, a bearing block 15 is fastened to the room-side wing end face, for example has an angular shape, as can be clearly seen in FIG. 9. The two bearing blocks 15 are mirror images of one another, the bearing axis 14 for the associated support arm 10 being accommodated in their horizontal leg 15a. The two support arms 10 and the two carriages 12 are also designed and arranged in mirror image to one another, so that the lower opening device 7 is formed by two identical units that are designed in mirror image to one another.

As can be seen particularly in FIGS. 7 and 8, the two carriages 12 are connected to one another in opposite directions by a differential coupling gear 16.

This differential coupling gear 16 has a thrust piece 20 on each of the two carriages 12, this thrust piece 20 being in the longitudinal direction or parallel to the direction of movement of the carriage 12 with the latter having an exclusively longitudinally slidable connection (20b).

On each thrust piece 20 a handlebar 17 engages with its one end via an articulated connection 19, which on the other hand, also by an articulation 18, is connected to the support arm 10 held pivotably about the axis 11 in the relevant carriage 12.

Support arm 10 and handlebar 17 cooperate with the carriage 12 and the thrust piece 20 which is guided longitudinally thereon in the manner of a so-called cardan or elliptical link. The operative connection is of such a type that the longitudinal displacement of the thrust piece 20 relative to the carriage 12 leading it, which is brought about by the link 17, the swivel arc height 35 of the end 14 of the arm 3 engaging the wing 3 during its swiveling movement about the bearing axis 11 on the carriage 12 corresponds.

Since the direction of movement of the thrust pieces 20 on the two carriages 12, due to the cardan and elliptical link kinematics of the differential Koppelgetriebes 16 opposite to the respective pivoting movement of the support arms 10 about their wing-side bearing axis 14 is forced, the two carriages 12 perform relative to each other on the stationary running rail 9 opposite opposing movements. When the support arms 10 move from the functional position of FIG. 7 into the functional position of FIG. 8, the carriages 12 are forcibly moved away from one another via the differential coupling gear 16, while, conversely, during the pivoting movement of the support arms 10 from the functional position according to FIG. 8 in the functional position of FIG. 7 are also inevitably approached again by the differential coupling gear 16.

The forced control of the trapezoidal link system of the opening device 7 in the region of the two carriages 12, which is effected via the differential coupling gear 16, has the result that, despite mutually opposite pivoting movement of the two support arms 10, a synchronous displacement of the wing 3 transversely to the plane of the fixed frame 1 is controlled.

In order for the sash to remain securely in the parallel storage position relative to the fixed frame 1 during its horizontal displacement, it is necessary to use at least the support arms 10 of the lower opening device 7 with respect to the fixed frame 1 or the carriage 12 guided on its running rail 9 by a special locking device 21 to block. On the other hand, by triggering the locking device 21, the blocking of the parallel storage position for the extension arms 10 must, however, be released as soon as the sash 3 reaches its final sliding closing movement, so that it moves from the position according to FIG. 8 into the position according to FIG. 7 against the fixed frame 1 can be created.

7 and 8, each of the two carriages and the support arm 10 mounted thereon is assigned its own locking device 21, the arrangement and mode of operation of such a locking device 21 being shown in FIGS. 10 and 11.

On each carriage 12, for example on the extended bearing axis 22 of a roller 13, a pawl 23 is pivotally supported in the vertical direction, which forms a two-armed lever, the lever arms 24 and 25 of which extend from the bearing axis 22 in opposite directions.

The lever arm 24 is facing the carriage-side end of the support arm 10, in such a way that its free end edge 26 can come into operative connection with a support surface 27 of a bearing eye 28, which projects sideways from the support arm 10 at an obtuse angle and into a recess 29 on Carriage 12 protrudes, which is penetrated by the bearing axis 11.

In the parallel storage position of the support arm 10 according to FIG. 8, the transverse edge 26 of the lever arm 24 can reach the support surface 27 on the bearing eye 28 of the support arm 10 and thereby block it against pivoting relative to the carriage 12 into the position according to FIG. 7. The lever arm 24 of the pawl 23 thus forms the actual locking member of the locking device 21, via which the parallel storage position of the support arm 10 with respect to the carriage 12 can be blocked.

So that the support arm 10 is released relative to the carriage 12 for a pivoting movement as soon as the wing reaches the sliding closing end position relative to the fixed frame 1 during its horizontal displacement, the second lever arm 25 of the pawl 23 acts via a control cam 30 with a control cam 31 of a stationary on fixed frame 1 attached actuator, as shown in Figs. 10 and 11. 10 and 11 from left to right - horizontally displaced relative to the fixed frame 1 in the opening direction, then the pawl 23 is forcibly pivoted over the control cam 30 and the control cam 31 such that the end edge 26 of its lever arm 24 occurs before the support surface 27 of the bearing eye 28 on the support arm 10 and blocks or sets it in the parallel storage position according to FIG. 8 against the carriage 12.

However, if the sash 3 is moved horizontally relative to the fixed frame 1 in the closing direction - from right to left - according to FIGS. 10 and 11, then a pivoting movement is forced over the control cam 30 and the control cam 31 of the pawl 23, through which the end edge 26 of its lever arm 24 emerges from the area of the support surface 27 of the bearing eye 28. The support arm 10 is then free relative to the carriage 12 and can pivot about the bearing axis 11 from the parallel storage position according to FIG. 8 into the closed position according to FIG. 7.

As already mentioned, each of the two carriages 12 of the opening device according to FIGS. 7 and 8 is equipped with its own locking device 21. However, only one of these locking devices 21 is sufficient to secure the parallel storage position of the two support arms 10 of the opening device 7, because these are inevitably in actuation connection via the coupling gear 16.

It has proven itself in practical use to make only the locking device 21 provided between the closing-side carriage 12 and its support arm 10 effective, while the locking device 21 is fixed to the other carriage in its inactive position, for example by a clamping screw 33.

Of course, it is also easily conceivable to make the locking devices 21 of the two carriages 12 functional and to design and arrange the associated frame-side actuators 32 in such a way that they ensure proper movement control of both locking devices 21.

Finally, it should also be mentioned that, according to FIG. 9, a cover profile 34 can be attached between the two bearing blocks 15 on the lower cross member 3a.
