Description

The invention relates to an opening limiter device for a window arrangement, having an opening limiter which has a slider movable in the fold of the window arrangement and a limiter arm connected in an articulated manner to the slider.

Opening restrictors of the aforementioned type are already known from practice. Such opening restrictors are used on windows, especially in public areas, such as kindergartens. About the opening restrictors to ensure that the associated windows are not accidentally opened too far for safety reasons. As a rule, opening limiters of the aforementioned type are lockable. In this case, a lock is mounted in the sash frame, which specifies the maximum travel of the slider until it reaches the opening-limited position.

An opening limiting device with an opening limiter and a lock is already out of the EP 2 107 194 A1 known. A disadvantage of the known Öffnungsbegrenzereinrichtung is that when mounting the lock on the sash must be paid exactly to where the lock is mounted in the sash frame. The mounting point ultimately defines the stop for the slider and thus also the maximum travel to the opening-limited position. If the lock is not mounted exactly, the result is either a gap that is too large or too small in the opening-limited position.

Object of the present invention is therefore to provide an opening limiter device of the type mentioned above, with which the opening-limited position is precisely adjustable.

The above object is achieved according to the invention in an opening limiter of the aforementioned type essentially in that the Öffnungsbegrenzer has an adjustable in the fold of the window assembly actuator body with a longitudinal rail and that the slider is guided on the rail of the actuating body and is movable relative to the actuating body via a travel ,

In the invention, it is in contrast to the prior art so that in addition to the slider, a control body is provided on which the slider is guided. Due to the rail of the actuator, which has a predetermined length, the travel can be specified exactly to the opening-limited position. Ultimately, the travel and thus the correct opening-limited position depends ultimately only on the unit to be arranged in the fold of the actuator and the slider and not from the arrangement of a lock or other locking device. The slider as such ultimately does not interact with a lock or other locking device.

Due to the possibility of relative movement of the slider connected to the Begrenzerarm to the actuating body, it is possible to move the window sash from the opening-limited position to the closed position to close the window without moving the actuator body. In this case, the travel is then at least designed so that the slider on the actuator from a rear end position corresponding to the opening-limited position of the sash, in a front end position corresponding to the closed position of the window sash to move. It goes without saying that this movement is, of course, also possible the other way around.

It is particularly advantageous if the travel and / or the adjusting body is adjustable in length. In this way, it is then possible to increase the gap of the window sash, if necessary, or to reduce it. Structurally, it is provided that the adjusting body can be extended or shortened, with the result that the Aufschwenkwinkel the window sash can be increased or decreased with a fixed actuator body.

For structural design, the actuating body in this case has a front actuating body part, wherein the front actuating body part and the rail on which the slider runs are adjustable in the longitudinal direction relative to one another.

The adjustment of the two relatively arranged control body parts, namely the front Stellkörperteils and the rail, preferably via a manually operable adjusting spindle, which is provided in particular in the front actuating body part. The rotatably mounted spindle preferably cooperates with a longitudinally movable actuator running on the spindle. Coupled to the actuating element is then the rail, so that an adjustment of the spindle to a movement of the actuating element and thus to a movement of the rail leads. In a preferred embodiment, an adjustment of up to ± 20 mm, more preferably between ± 5 to ± 15 mm and in particular of about ± 10 mm is provided.

To limit the relative movement of the slider to the actuating body, an end stop is provided on the end of the rail.

In order to achieve a determination of the slider with respect to the relative movement of the slider to the rail, it is provided in a preferred embodiment of the invention that the slider can be locked to the end stop.

In principle, it is possible that the adjusting body is fixedly mounted in the fold of the window assembly. Complete opening of the window sash beyond the opening-limited position would then be possible, for example, in that the limiter arm is released from the slider and / or from a bearing on which the other end of the limiter arm is articulated. In a preferred embodiment of the invention, the adjusting body is designed for displaceable arrangement in the sash frame and lockable by means of a locking device in an opening-limited position, in particular latched. The locking device can basically have at least one manually operable pusher. This can be provided on the outside of the sash frame. Basically, two pushers, which may be formed, for example in the form of snaps, may be provided to realize a parental control, which are spaced apart over a sufficient distance. About the one or more pushers, for example, a locking pin can be released, which serves to determine or locking the actuator.

Alternatively, the locking device may also have a lock which can be actuated via a key for releasing a latching bolt of the locking device. The locking pin is latched with the Öffnungsbegrenzer. Preferably, the lock is designed such that the locking pin is extended when the key is removed and projects beyond the lock housing of the cylinder lock, wherein the locking pin is retractable only by closing with inserted key. This has the significant advantage that it is in principle possible after opening the window sash by swinging the door completely swing open the window sash, after completion of the cleaning or maintenance pivoting of the window sash is sufficient to come again to a closed position in the opening-limited position , This is ultimately no separate key operation required. If the window sash is pivoted out of the open position into the closed position, the locking bolt ultimately engages in the opening limiter when the predetermined opening-limited position has been reached. To achieve this position, a key-operated closing of the lock and thus the supervisor with the key is no longer necessary. Thus, the person who has performed maintenance or cleaning work, by itself, the window sash to pivot back into the closed opening-limited position. Ultimately, this is therefore possible because the locking bolt basically protrudes with the key removed and, when the wing has been moved out of the opening-limited, closed position, always locked again by itself when the Öffnungsbegrenzer is moved past the resilient locking pin.

It is understood that the aforementioned function of the locking bolt is possible even with a different type of locking device, so even without removable key. The key function then assumes an actuating element of the locking device, which acts in a corresponding manner on the locking pin.

In a constructive embodiment of the invention, the Öffnungsbegrenzer next to the actuator body and the Begrenzerarm a frame bearing, which is ultimately intended to be arranged on the window frame of the window assembly and for local assembly. The adjusting body is preferably provided for displaceable arrangement in the window sash frame, wherein the Begrenzerarm connects the frame bearing and the actuating body or the slider. Due to the fixed arrangement of the frame bearing and the connection of the frame bearing with the Begrenzerarm ultimately results in the opening or closing of the sash moving the arranged in the sash frame actuator. It should be noted, however, that the adjusting body can be provided in principle in the fold of the window frame, the frame bearing is then attached to the sash frame.

To realize the latching connection between the opening limiter and the locking pin of the locking device, the adjusting body on its side facing the locking bolt on a particular closed detent opening, which prevents movement of the actuating body in the longitudinal direction after latching of the locking bolt. The detent opening is associated with at least one run-on slope in the direction of movement. Depending on the function of the opening delimiter and the design of the detent opening, in principle, a ramp can be formed in both displacement directions be provided on the actuating body. In any case, the realization of a ramp in the direction of movement of the actuating body is particularly preferred from the swung-open state of the window sash in the direction of the closed state.

It has proved to be advantageous that the detent opening is designed as a transverse to the direction of displacement of the actuating body aligned slot. This elongated hole training ensures a secure locking even if it comes with the longitudinal displacement movements to smaller transverse movements of the actuator. In addition, in principle, other mounting positions of the lock and / or the Öffnungsbegrenzers can be realized. The opening limiting device according to the invention is thus not limited to a specific window type. Moreover, the opening limiter device according to the invention is in principle not limited to windows. It can also be used on doors.

Furthermore, it has proven to be advantageous that the width of the slot corresponds at least substantially to the diameter of the locking bolt, so that at least substantially results in backlash when latching locking bolt in the direction of displacement.

In a similar manner as with respect to the slider, an end stop in the form of a final bearing for the actuating body is also provided for the actuating body. This stop is then to be arranged in the fold of the window assembly. Also in this context, it makes sense to lock the actuator body with the repository to have a defined end position.

In particular, in connection with the latching connection between the end stop and the slider or between the end bearing and the actuating body, it is particularly advantageous if the holding force of the latching connection is adjustable. Depending on the desired application, so that the force to reach the locking connection or to release the locking connection can be changed accordingly.

In a preferred embodiment for adjusting the holding force of the latching connection is provided that the end stop and / or the end bearing has a holding pin with an elliptical holding head, in which case the rotational position of the holding head is adjustable. This ultimately results in a continuous adjustment of the holding force. If the holding head is rotated so that the smallest width results in the direction of movement, the locking legs, which are for snapping onto the holding head are provided, only slightly pressed apart, so that only low holding forces occur. On the other hand, if the holding head is rotated in such a way that the maximum width of the holding head results, this results in the maximum holding force due to a corresponding spreading of the locking legs.

For certain applications, it may be useful to be able to slow down the pivoting movement of the window sash. For this purpose, a braking device according to the invention is provided in particular by means of an adjusting spindle adjustable braking force, which is associated with the slider in a preferred embodiment of the invention. Due to the assignment of the braking device to the slider results on the one hand, the effect that the movement of the slider is braked relative to the actuating body or the rail, on the other hand, the movement of the actuator is slowed down as a whole at a movement of the actuator at the same time the slider of the adjusting body mounted slider is moved.

In a particularly preferred, constructive embodiment, the braking device has an adjustable clamping body and a provided in the slider, consisting of an elastic material clamping body receptacle for receiving the clamping body. In this case, the clamping body preferably has at least one conical outer side, wherein the clamping body receptacle can have at least one conical inner side. It is particularly preferred that both the clamping body and the clamping body receiving mutually corresponding sides. In any case, it is due to the taper of the clamping body and / or the clamping body receiving so that at least one of an elastic material existing wall of the clamping body is pressed depending on the clamping position of the clamping body to the outside. If the opening limiting device is installed, the outwardly pressed wall of the clamping body receptacle counteracts a corresponding guide or rail in the fold of the window sash frame, so that there results a frictional engagement and thus the desired braking.

It is particularly preferred in this context if the clamping body ultimately interacts with a spindle mounted on the slider and thus acts as a movable adjusting element which is longitudinally displaceable within the clamping body receiving.

Moreover, the present invention relates to a window assembly comprising a window frame, a window sash having window sash and an opening limiter device of the aforementioned kind. In this context it should be understood that features previously described in connection with the orifice restrictor are also provided in a similar manner to a window assembly in which an orifice restrictor is incorporated. In this respect, reference is made to the above statements accordingly.

In connection with the window arrangement, it offers to provide the locking device, in particular in the lower region of the sash frame, wherein the locking device should then be actuated from the inside of the window sash. If the locking device is designed as a pusher or push-button device, it is additionally possible to provide another such device, which is to be arranged at another point, in order to form a child safety device.

Furthermore, the invention relates to a slider for a Öffnungsbegrenzer an opening limiter device, in particular of the aforementioned type, for a window assembly, in particular of the aforementioned type, wherein on the outside of the slider guide elements are provided for outside guidance in the fold of the window assembly.

A slider of the aforementioned type is also from the EP 2 107 194 known. The well-known glider is on the in the EP 2 107 194 A1 limited embodiment described. The glider does not have any special functions.

Object of the present invention, it is now also to provide a slider available that has extended applications.

The aforementioned object is inventively achieved in that the slider is designed in such a modular manner that in the slider is a receptacle for the demand arrangement of a braking device, in particular according to one of the preceding claims, is provided and / or that the underside of the slider a stepped guide to the need of the arrangement Slider on a rail of a control body, in particular according to one of the preceding claims, is provided.

The inventive design makes it possible to use the slider in connection with an opening limiter, which ultimately has no special functions. In the simplest case, the slider is slidable in a guide in the fold of the window assembly.

The slider according to the invention, which may otherwise have all the above-described, the slider as such relevant features for themselves or in any combination, is otherwise designed such that a braking device can be realized or mounted on it. This may be the braking device described above. However, the braking device can also be designed in other ways. In any case, however, a receptacle is required, which receives the corresponding braking means of the braking device.

In addition, the slider preferably has a stepped guide on the underside, so that it can be arranged, if required, on a rail of an actuating body, in particular of the aforementioned type. The stepped guide is required in order to record the height of the rail of the actuator can. The slider is thus provided with corresponding guide means for the rail of the actuating body. This is a very space-saving arrangement that takes into account the tight space in the fold.

As a result, the modular slider according to the invention can thus be used on its own, with or without adjusting body and with or without braking device. For all applications ultimately only a single slider is required.

It is particularly favorable in this context that the slider has a latching opening at its rear end. This is designed as needed for interaction with an end stop to be fastened in the seam of the window arrangement or an end bearing of the setting element provided at the end of the rail.

Other features, advantages and applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing and the drawing itself. In this case, all described and / or illustrated features, alone or in any combination, the subject of the present invention, regardless of their Summary in the claims or their dependency.

In Fig. 1 a window assembly 1 is shown, which has a window frame 2 and a window sash 3. The window sash 3, in turn, has a sash frame 4, on which a rotary handle 5 is located on the inside. In the lower frame part of the sash frame 4 is an opening limiter device 6, which is provided for adjusting the opening width of the window sash 3. The opening delimiting device 6 has an opening delimiter 7 and a lock, which can be actuated by means of a key, not shown, as a locking device, which in the present case is designed as a cylinder lock 8. Thus, the opening restrictor 6 is lockable. As can be seen in particular Fig. 1 shows, the lock 8 is provided in the lower region of the sash frame 4 and from the inside of the sash 3, on which also the rotary handle 5 is closable.

In one embodiment, not shown, instead of the lock as a locking device and a pusher, for example in the form of a push button device or another actuator, be provided. The opening limiter device does not have to be lockable with it.

The lock 8, which in the exploded view according to Fig. 3 is best shown, has a resilient locking pin 9 which is latched to the Öffnungsbegrenzer 7. In this case, the lock 8 is formed such that the locking pin 9 with the key removed, as in Fig. 3 is shown, is extended, so that the locking pin 9 projects in the radial direction over the lock housing 10. The direction of movement of the resilient locking bolt 9 is thus transversely to the longitudinal movement direction L of the opening limiter 7 in the sash frame 4 when pivoting the sash 3 relative to the window frame 2. The lock 8 is further designed such that the locking pin 9 is retractable only by closing with inserted key. This ultimately means that with inserted key and closing the lock cylinder, for example, in an angular position between 90 ° and 180 °, the locking pin 9 is retracted into the lock housing 10 and thus the detent position is unlocked or released. If the key is returned to the zero position and withdrawn, this leads to a rebound and thus to a projection of the locking bolt 9 from the lock housing 10th

The Öffnungsbegrenzer 7 has a frame bearing 11, a control body 12 and a Begrenzerarm 13. The frame bearing 11 is provided for attachment to the window frame 2. In the assembled state, the frame bearing 11 is bolted to the window frame 2. The actuator body 12 is fixed in the assembled state on the sash frame 4, either directly in a corresponding profile in the fold or in a profile attached to the sash frame 4 profile in the fold. In any case, the adjusting body 12 is held captive in the associated profile and slidable therein. Moreover, the adjusting body 12 is provided for locking with the locking pin 9 of the lock 8. The Begrenzerarm 13 is connected both with the frame bearing 11 and with the actuating body 12, with the latter but only indirectly, articulated.

It should be pointed out that in particular in an embodiment in which no locking device is provided in the form of a pusher, push button or a lock, the adjusting body can then also be permanently mounted. In this case, the frame bearing 11 can then be attached to the window sash frame, while the adjusting body would then be attached to the window frame.

The actuating body 12 has to realize the latching connection with the locking pin 9 has a latching opening 14 (see. Fig. 4 ). The front end of the actuating body 12 is provided with a ramp 15, which leads from the front end of the actuating body 12 to the latching opening 14. The width of the oblong hole corresponds at least substantially to the diameter of the locking bolt 9. In this way, it is ensured that the locking pin 9 even when moving transversely to the direction L can still be caught by the slot, is arranged in the trapped or locked state in the direction L but at least substantially free of play.

The opening limiter 7 furthermore has a slider 17 guided on a rail 16 of the adjusting body 12. The slider 17 has a stepped guide 39 for the rail 16 and is movable relative to the adjusting body 12 and the rail 16 via a travel. The stepped guide 39 has such a depth that the height of the rail 16 is completely received therein. On the underside, the rail 16 is aligned with the underside of the slider 17. In addition, the slider 17 is connected on the upper side with the Begrenzerarm 13, so that ultimately results in an indirect connection of the Begrenzerarms 13 to the actuating body 12 via the slider 17. The travel is designed such that the slider 17 is movable in a latched with the locking pin 9 adjusting body 12 from a rear end position to a front end position and vice versa. The rear end position corresponds to the closed, opening-limited opening position of the window sash 3, while the front end position relative to the window sash 3 corresponds to the closed position of the window sash 3.

The aforementioned travel is adjustable in length. Concretely, this is the actuating body 12 formed in several parts. Thus, a front actuating body part 18 is provided, which is formed separately from the rail 16. Finally, the front actuating body part 18 and the rail 16 in the longitudinal direction L are adjustable relative to each other. To set the travel, a manually operable adjusting spindle 19 is mounted with a movable on the adjusting spindle 19 actuator 20 in the front actuating body part 18. The actuator 20 is coupled to the rail 16. The adjusting spindle 19 has at its end an engaging portion 21 for engaging / applying a tool. By turning the adjusting spindle 19, the adjusting element 20 can be moved relative to the spindle 19 in and counter to the longitudinal direction L. In this way, there is an extension or shortening of the actuating body 12 and thus also of the travel.

As can be seen in particular Fig. 3 results in an end stop 22 is provided on the end of the rail 16. With this end stop 22 of the slider 17 can be locked. For this purpose, the slider 17 at the end between two locking legs 23 has a latching opening 24. It is understood that the slider 17 is made of a corresponding elastic material, so that the locking legs 23 are correspondingly resilient.

Furthermore, the Öffnungsbegrenzer 7 a repository 25 as an end stop for the actuating body 12. The repository 25 is provided for arrangement and attachment in the sash frame 4. The end bearing 25 limits the maximum pivoting movement of the window sash 3. The actuating body 12 can be latched to the end bearing 25. The locking connection is formed in the same manner as the locking connection between the slider 17 and the end stop 22. Accordingly, the end bearing 25 as well as the end stop 22 on a retaining pin 26 on which the locking legs 27 are latched with the locking opening 28 therebetween. The holding force of the respective latching connection between the end stop 22 and the slider 17 on the one hand and between the end bearing 25 and between the adjusting body 12 on the other hand adjustable. This is realized in that the respective holding pin 26 has an elliptical holding head with a tool engagement portion, whereby the rotational position of the holding head is adjustable.

The slider 17 has a braking device 29 with adjustable braking force. To adjust the braking force is an adjusting spindle 30 which is mounted in the slider 17. The adjusting spindle 30 has at its end an engaging portion 31 for tool actuation. Furthermore, the braking device 29 has an adjustable clamping body 32 and provided in the slider 17 clamping body receptacle 33 for receiving the clamping body 32. The slider 17 itself is made of an elastic material.

As can be seen in particular Fig. 7 results, the clamping body 32 is formed on opposite sides 34 conical. Also, the clamping body receptacle 33 is formed on opposite sides 35 in a corresponding manner conical. This results in a tapered clamping body receptacle 33, on which the correspondingly conical clamping body 33 rests flat. If the clamping body 33, starting from the in Fig. 7 attracted shown position, in the drawing according to Fig. 7 to the left, they expand to the body 33 subsequent side walls 36 to the outside. This ultimately leads to a frictional engagement on the outer guide, in or on which the slider 17 is guided on the window side.

The slider 17 is otherwise modular. As can be seen from a comparison of Fig. 2 and 5 results, the sliders 17 differ only in that in the embodiment according to Fig. 2 a braking device 29 is provided, while in the embodiment according to Fig. 5 has been omitted. Changes to the main body of the slider 17 are not required here. Only the clamping body receptacle is not provided with the clamping body and thus it is also missing on the adjusting spindle 30th

In addition, it is in principle even possible to manage without the adjusting body and / or without the lock or another locking device. Such embodiments are in the Fig. 6 (with braking device) and Fig. 8 (Without braking device) shown In this case, the slider 17 acts ultimately as a control body which is movable between a rear position, limited by the end bearing 25 and a front position, which is limited by a stop, not shown, back and forth. In this case, then there is an opening limiter device that is not lockable.

Visible, the slider 17 is a modular element, the outside corresponding guide means 40 for cooperation with corresponding guide means on the fold, d. H. on the window sash 3 or on the sash frame 4, wherein the slider 17 can be used with and without adjusting body 12.

Moreover, it is understood that all previously described in connection with the Öffnungsbegrenzereinrichtung 6 and the Öffnungsbegrenzer 7 the slider 17 relevant characteristics also apply to the slider as such, ie in particular without the actuator. The slider as a modular element in its simplest embodiment is in Fig. 8 shown at an opening limiting device 6. The slider has no braking device and also a control body is not provided. The slider 17 is ultimately used directly in the fold of the window assembly and acts on the guide means 40 with corresponding guide means at the fold.

In the embodiment according to Fig. 6 the slider has a braking device 29 in the previously described function of the opening limiting device.

At the in Fig. 5 In the embodiment shown, the slider interacts with a setting element 12, but has no braking device. In the Fig. 2 illustrated embodiment corresponds to the according Fig. 5 , but in addition a braking device is provided.

The function of the Öffnungsbegrenzers 7 invention with actuator 12 and lock 8 is now as follows. In the closed state of the window, the locking pin 9 engages in the latching opening 14. The actuating body is not longitudinally displaceable. The front end 37 of the slider 17 is directed to the rear end 38 of the front actuating body part 18. The two ends 37, 38 are either spaced a small distance apart or lie directly against each other. The window sash 3 can now be opened via the handle 5 and swung over a predetermined travel of the slider 17, and that is maximum so far until the retaining pin 26 engages in the detent opening 24. In this state, the window has a maximum opening width of, for example, 120 mm. About the adjusting spindle 19, the travel and thus the opening width of the window sash 3 can be increased or decreased. In any case, after locking the slider 17 on the retaining pin 26 further pivoting of the sash 3 in the locked state of the actuating body 12 is no longer possible.

Now, if the associated key is inserted and closed in the lock 8, this leads to a retraction of the locking bolt 9 in the lock housing 10. As a result, the adjusting body 12 is released. It is now possible to further open the window sash 3, to the extent that the retaining pin 26 of the end bearing 25 engages in the locking opening 28. In this state, then the maximum Aufschwenkstellung is reached. In this state, the key can be removed from the lock 8, resulting in an extension of the locking bolt 9 from the lock housing 10.

Now, if the sash 3 is closed, this leads to a unlatching of the actuating body 12 with the repository 25. At the same time, before, or even after it can lead to a disengagement of the slider 17 with the end stop 22. In any case, the pivoting movement of the window sash 3 leads to a longitudinal displacement of the actuating body 12 in the direction L. As soon as the actuator body 12 reaches the locking pin 9, this is pressed over the ramp 15 until it finally into the Detent opening 14 engages. The actuator is then detected. In this state, a renewed pivoting of the window sash 3 is no longer possible. However, due to the relative movement of the slider 17 to the rail 16, still a closing of the window and a reopening to the closed opening limited position on the slider 17 is possible.
