Description

The invention relates to a fitting for a wing of a window, a door or the like which is held by means of at least one opening arm. With the aid of the opening arm or arms, at least one end of a wing can be pivoted relative to its frame, the wall or the like. So bring this wing at least into a tilt or fold position. How to stop this wing end or possibly the whole wing depends on the number, training and articulation of the or the extension arms. If forces act on a wing opened in this way, there is a risk that the wing will be closed again or at least rattle and thereby cause undesirable noises.

The object of the invention is therefore to design the fitting so that the wing is held securely in the deployed or parked position.

To achieve this object, it is proposed according to the invention that the fitting is designed in accordance with the preamble of claim i in accordance with the characterizing part of this claim. The locking device which is effective in the opened or parked position of the wing prevents undesired resetting and thus also slamming. If several extension arms are used, it is sufficient in itself to secure only one or only a part of them with such a locking device. There are fittings which, for example, have four extension arms, with the aid of which the sash can be parked in parallel and two of which are not secured against undesired resetting. If one of them is secured with the locking device according to the invention, which is effective in the opening position, this is entirely sufficient for a secure locking of the wing in the parallel position.

A further development of the invention provides that the locking device is formed by a latching receptacle and a spring-loaded latching member which can be latched therein, the latching receptacle in particular being located on the extension arm and the latching member on the wing. When the sash is closed, the latching receptacle is in a position that is inaccessible for the latching member and both only come into an assignment suitable for engaging when the extension arm has assumed its pivoting end position when the sash is opened. Due to the spring loading, the locking element jumps into the locking receptacle at the moment when the force of the loading spring can have an effect. It is equivalent whether the latching receptacle moves against the latching member or vice versa. The disengagement takes place either by hand or by a sensible mechanism. It can be operated directly or indirectly via the movement of another part or the entire wing.

A particularly preferred embodiment of a fitting for a parallel-adjustable wing with at least two upper and two lower extension arms is characterized in that at least one of the lower extension arms, in particular the one assigned to the closing side of the wing, is provided with a locking device. Such a wing can be parked, for example, in such a way that it is first moved into a tilted position and subsequently also the lower one Turns off the end. It is also conceivable, however, to pivot all four extension arms simultaneously, so that the wing is moved parallel to itself when it is parked in parallel. In the former case, the tilting of the wing is usually achieved by actuating the handle with which the wing is also unlocked or locked in the closed position. It is usually intended that the wing can either be left in its tilted position or can be brought into the parallel storage position via the tilted position. The latter can either be used as a ventilation position: or as a starting position for moving the wing in parallel to a second wing or a fixed field.

If the fitting is so designed; that with its help the tilting of the sash, i.e. the swiveling out of only the upper extension arms and can not be influenced by the handle on the lower extension arms, the upper extension arms can be secured against unwanted turning back via their upper opening mechanism, while the lower arms, which can only be pivoted by pulling the wing out at its lower end by hand, require protection against undesired turning back. This is the case described above, in which it is sufficient to provide only one of the four extension arms with a locking device which is effective only in the opening position. If namely three of the four arms against unwanted Back turning are secured, so acting on the parallelabge wing attacking forces, such as the wind pressure mentioned, can not have a restoring effect. On the other hand, it is cheaper for cost reasons if only one locking device is required. In addition, an automatic unlocking of the locking device, which can be provided, for example, with a sliding sash placed in parallel, can be made simpler if only one locking device is to be unlocked.

The reverse is also conceivable in the case of a wing which can be set down in parallel and has four extension arms, in which the wing is first brought into a folding position and the parallel turn-off is subsequently effected by pivoting the upper wing end by hand. In this case, the one or more effective locking devices according to the invention are provided on the upper extension arm or arms. However, this embodiment is not preferred over the one described above, if only because it is more common to bring a wing into the tilt position than into the folding position.

Another embodiment of the invention is characterized in that at least the lower lower arm, which is at the front in the sliding closing direction, on a carriage or running shoe. Like. The wing hinges and the spring-loaded locking member is slidably mounted thereon. If only one of the two lower extension arms is equipped with a locking device, is of course only on one of the carriages or drl. a spring-loaded locking member slidably mounted. To avoid special shapes, however, all four extension arms can be designed identically, that is, they can also be provided with a holder to which no locking member is assigned.

Another variant of the early feature is characterized in that the latching element can be latched in the sliding direction of the wing and is connected via a sliding member to a trigger which, when the wing is closed in the sliding direction, interacts with a fixed, in particular on a frame or the like . So if you push the wing in parallel and moved in the opening direction back again, the sliding movement of the wing can be used for a disengaging movement. As soon as the sliding element connected to the locking element hits the stationary overrun element, the sliding element can no longer take part in the rest of the sliding-closing movement of the leaf and this leads to the locking element stopping. However, because the extension arm is articulated with the latching receptacle on the carriage and this takes part in the rest of the sliding-closing movement, the latching receptacle is, as it were, withdrawn from the latching member, so that the locking is released. At the same time, the loading spring of the spring-loaded locking device is then tensioned. To After the locking device has been disengaged, the sliding sash has reached its sliding end position and can subsequently be transferred into the tilting position and finally also into the closed position.

Another preferred embodiment is characterized in that the sliding member is designed as a longitudinally displaceable frame or the like mounted frame, the longitudinal members of which are arranged on both sides of the carriage, while the front cross member in the sliding-closing direction carries the trigger and the rear cross member carries the fast member or form. This construction enables both the inexpensive attachment of the trigger and the locking device, as well as an advantageous storage of the deployment arm in question.

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

• 1 shows a window provided with two sashes, of which the left one is held by means of the fitting according to the invention,
• 2 shows a section along the line II-II of FIG. 1, with the left wing in the closed position,
• Figure 3 is a similar representation with the left wing in parallel storage
• FIG. 4 shows a top view of the fitting with the sash closed on an enlarged scale,
• FIG. 5, also on an enlarged scale, the fitting with the sash positioned parallel,
• FIG. 6 shows a view of the fitting according to FIG. 4 from the front,
• 7 shows a section along the line VII-VII of FIG. 6.

In the exemplary embodiment, the left wing 1 is articulated on a frame 6 by means of four extension arms 2, 3, 4, 5, but the fitting according to the invention can also be used if the wing, for example at its upper end, is tilted by only one extension arm is supported. The second wing 7 located on the right in the exemplary embodiment can be mounted on the frame in a known manner or can also be designed as a fixed, in particular removable, field. In the parallel storage position, the wing 1 can be moved in the direction of arrow 8, so that it is in the end position before the second Wing 7 comes to a standstill.

If one unlocks the wing 1 by means of a window gear 9, which can be done by turning the handle 10 in the direction of arrow 11, for example, and then turns the handle 10 further from a horizontal to a vertical position by 90 °, this is done via the connecting rod connection 12 and the upper ones Extension arms 2 and 3 tilt the wing 1 in the manner known for tilt and turn windows and doors. In a known manner, you can lock and secure this tilt position either via the gear 9 or other elements of the opening mechanism. Accordingly, the upper extension arms 2 and 3 are, at least in detail, of a different construction than the lower extension arms 4 and 5. The design of the fitting according to the invention thus relates only to the lower extension arms 4 and 5 in the exemplary embodiment. With reference to FIGS the lower arm 4 was also addressed, but of course these statements also apply to the arm 5.

The extension arm 4 is rotatably supported by a first bearing pin 13 on the wing 1 and a second bearing pin 14 on a carriage 15. If, at its lower end, the wing 1 in the tilted position is pivoted, for example by hand, into the interior of the room, this leads to a rotating movement of the deployment arms 4 and 5 from the position shown in FIG the apparent from Fig. 3. In the rotary end position according to FIG. 3, a blocking device 16, which is effective at least on the lower extension arm 4, comes into operation. It consists of a latching receptacle 17 of the extension arm 4 and a spring-loaded latching member 18 which can be latched therein. It is fastened to a rear cross member 19 of a frame 20 and spring-loaded in the sense of arrow 22 by the spring 21 designed as a helical compression spring. This spring is supported on the one hand in a bore 23 of a front cross member 24 of the frame 20 and on the other hand on a base body 25 of the carriage 15. The cross members 19 and 24 are connected via two longitudinal members 26 and 27, which are located on the left and right of the base body 25, the four parts mentioned representing the frame 20 mentioned.

Since the upper extension arms 2 and 3, as explained, can be secured against undesired turning back in a known manner, it is in itself sufficient if one of the lower extension arms 4 and 5 has only the lower extension arm 4 in the sliding-closing direction 28 with a Locking device 16 provides. This makes the automatic triggering of the locking device 16 described below easier when the parallel-opened wing opened in the direction of the arrow 8 is closed, but of course an automatic triggering can also be achieved if a locking device 16 is attached to the lower extension arm 5.

The or each spring-loaded locking member 18 is designed as a longitudinally displaceable bolt, in particular with a thickened head tapering towards its free end, and the locking receptacle 17 in the extension arm 4 is designed as a notch, groove or the like, the shape of which is expediently the Head shape of the locking member 18 is adapted. Due to the fixed connection of the locking member 18 with the rear cross member 19 or the sliding member 30 designed as a frame 20, the displacement takes place indirectly via the movement of the frame 20. The locking of the locking member 18 accordingly takes place in the sliding closing direction 22 of the wing 1, while the Disengagement is achieved by means of a trigger 29 on the sliding member 30 and an overrun element 31. The latter is mounted on the lower cross member 32 of the frame 6 in the region of the running rail 33 for the carriage 15. The trigger 29 is formed by the front cross member 24 of the frame or an elastic buffer, not shown, inserted therein. If the buffer is missing, the front cross member 24 has the necessary elasticity.

If one pushes the first wing 1, which is parked in parallel and at least partially displaced in the direction of arrow 8 in front of the second wing 7 or the like, in the direction of arrow 28, that is to say in the sliding closing direction, the buffer or the front end face of the trigger 29 hits on the ramp element 31 as soon as the wing 1 of the frame opening 34 is approximately opposite.

The overrun element 31 prevents further displacement of the sliding member 30 or frame 20 in the direction of the arrow 28, but the carriage 15 together with the sash can be moved relative to the frame 20 by a smaller amount of a few millimeters. This is sufficient to remove the locking receptacle 17 from the now stationary locking member 18 and thereby to cause the locking device 16 to disengage. In the displacement end position of the wing 1, which is of course also a displacement end position of the two carriages 15 coupled to one another via a rigid connecting member 35, the wing 1 stands exactly in front of the frame opening 34, so that now at least its lower end can be pivoted towards the frame 6 can, causing the wing to return to the tilted position. The spring 21 is in its tensioned or maximum tensioned state (FIGS. 4 and 6).

The front cross member 24 is located in front of the carriage 15 or the front end of the carriage body 25 in the sliding closing direction 22. In contrast, the rear cross member 19 penetrates an opening 38 of the carriage 15 or its, in particular between the two wheels 36 and 37 Base body 25. The latter is only possible, however, if an opening 39 and 40 is also provided on each of the two longitudinal beams 26 and 27. If a right and left version is provided in a preferred manner, openings 41 and are additionally made on the two longitudinal beams 26 and 27 42 on. In addition, corresponding openings or windows 43 and 44 in the carriage or its base body 25 are also provided for the wheels 36 and 37.

7 shows that the upper and lower longitudinal edges of the two longitudinal members 26, 27 of the frame 20, each made of a flat sheet metal or the like, are bent at right angles to form slide rails 45, 46 and 47, 48, respectively . Each is slidably mounted in a guide groove or, as in the exemplary embodiment, a groove of the carriage or carriage body 25. 7 that the rear, the shaft 49 of the wedge-shaped locking member 18 receiving cross member 19 is guided on its top and bottom by longitudinal guides 50 and 51 on the carriage 15 in the direction of displacement of the wing 1.

If, in one embodiment according to the exemplary embodiment, both lower extension arms 4 and 5 are equipped with a locking device 16, then of course both must be triggered at the same time when the wing is pushed back in the direction of arrow 28. In this case, two overrun elements 31 are attached to the lower cross member 32, the side spacing of which corresponds to that of the carriage 15. Their height and the dimensioning of the two triggers 29 must be selected such that the trigger of the carriage carrying the raising arm 4 is not shown and is intended for the carriage of the raising arm 5 Overrun element runs over, so that each trigger can only interact with a single overrun element 31.
