DE10013697A1 - Door window check uses latching system composed of odd-sized teeth on support rod end co-operating with latches during casement movement. - Google Patents

Abstract

A latching recess (23) on one end (20) of the support rod (6b) works when the window casement pivots with a latch (26) to lock the rod against rotation. The recesses (23) are in tooth form and the rod symmetrical in its longitudinal axis (24) so the teeth (23) stand at right angles to this axis and thus form an arc (25). The teeth differ individually in size and one tooth (34) is arranged on the axis (24) and is smaller than the remaining teeth. Latch (26) uses its spring (31) to load permanently down on the clamp (30) so the clamp nose (32) necessarily connects positively to the teeth recesses (23) depending on the position of the extender (6a).

Description

The invention relates to a locking device for the wing of windows and Doors, the opening width of which on the one hand on the frame and on the other hand on the wing articulated pivot arm Display device can be limited in that this with a pin in a The longitudinal guide engages at its the open position of the wing facing end has a limit stop for the pin, a support arm is pivoted on the wing and on the extension arm.

Such a locking device is already known from EP 0 383 003 B1. This device is also attached to a display device, the Opening width on the one hand on the frame and on the other hand on Wing articulated arm is limited. The limitation forms a pin which engages in a longitudinal guide and on the in Opening position of the wing strikes the end. The attachment the locking device takes place via a drag lug on the pin is connected and is held displaceable relative to the longitudinal guide, wherein the drag tab carries a locking projection, which is adjacent to the Longitudinal guide assigned an elastically evasive locking cam stationary is. A carrier having the locking cam penetrates one Longitudinal slit or cutout in the drag flap, which by means of a Locking bolt, especially a screw, in front of or behind the Limit stop of the longitudinal guide z. B. is anchored to the wing, wherein a locking projection and locking cams laterally outside the Longitudinal slit or cutout on the drag strap and on the carrier are located. In addition, the locking device proves to be releasable Connection by pulling the drag link across one of their  Movement direction has open coupling mouth, which is detachable with the pin of the extension arm is to be coupled.

To all window sizes, depending on the size with the respective Display device are equipped with the state of the art to provide known locking device, it is required at least three to produce different sizes. According to the invention Locking device provided with a locking projection, the Snap projection achieves a fixation of the open position. In case of use it has It has been shown that the effect of the locking projection in coordination with the Wing sizes and thus the wing weight can be very different. The Locking device shown here is therefore from manufacturing costs to finally, to achieve an effective limitation, very high. One sees now several locking projections before, so the manufacturing cost is over so higher and the detent effect can vary very differently on that Impact windows.

Another known prior art is known from EP 0 803627 A2 out, this is a turn-tilt fitting with variable Night ventilation is concerned. In the known prior art is said to be simple Way a user-friendly determination of the wing in one Night ventilation position are made possible. This is between the faceplate and the support arm effective a locking device that the Pivotal movement of the support arm depending on the adjustment of the Drive rod blocked or released. To the actual turn-tilt fitting there is also a night ventilation position, whereby the fitting between these positions by means of the drive rod gearbox connected handle is actuated. The locking device includes one the faceplate pivotally mounted locking lever, which is connected to the Driving rod provided control cam can be actuated and with a pinion in Locking engagement can be brought about, which is firmly connected to the support arm Support arm axle is attached in a rotationally fixed manner. This makes it a variable Night ventilation position reached, blocking and releasing the Rotational movement can be achieved. When operating the operating handle of the  Turn-tilt fitting in the tilt position, the sash can move around its horizontal Swivel axis can be pivoted, it is now possible to move the wing in the desired position between the closed position and the maximum Determine the tilt opening position in which the handle from the tilt Switch position corresponding vertical position somewhat in the direction of the swivel Switch position is moved. A slight swiveling of the handle in this direction and thus a corresponding displacement of the drive rod leads to the blocking of the support arm and thus to the determination of Wing in a partial tilt position. This adjustment is released again in that the actuating handle is brought into the toggle switch position and so that the wing either in the full tilt position or in the closed position is transferable.

A disadvantage of the known solution is not only the requirement of high Component effort and thus an additional assembly work, but also that the locking device shown here is not subsequently in the the intended display device can be used. Furthermore, it shows up Handling for the user is sometimes very complex and complicated, on the one hand as they are an addition to the usual application of locking, turning, tilting and on the other hand that in order to achieve a blocking in Tilt position requires an operation of the operating handle, which has a disadvantageous effect on the user after repeated use.

The object of the invention is to provide a locking device which can be used structurally simple and inexpensive design of a Limitation of the opening of a window or door leaf that acts as a brake at the same time can be assigned to the appropriate display device.

This object is achieved according to the invention essentially in that the support arm has at least one locking recess at one end, which cooperates with a locking means when pivoting the wing and so that the support arm secures against rotation.  

This fitting according to the invention thus has the essential advantage that one the wing in the tilt switch position of its opening width or can limit the braking effect several times, with the components required very much is kept low and the display device easily with simple means can be retrofitted with the locking device according to the invention. For Achieving to keep the component effort as low as possible is the support link, which is used as a standard component in the display device and thus for known prior art, provided with recesses been formed, which are preferably tooth-shaped and thus a relative achieve good rest.

According to a further feature of the invention, the support arm is in his Longitudinal axis formed symmetrically. Because of this, the Locking device for both a right and for a Left usability usable without any addition.

According to a further feature of the invention, it is advantageous that the Locking recesses are arranged transversely to the longitudinal axis of the support arm and form an arch. The recesses fit the Sequence of movements of the tilt opening movement of the opening device on and achieve a relatively even locking effect, as well as one low wear of the locking device.

The target, the locking device and the braking force of the tilt opening position Another area is to influence areas achieved that the latching recess considered individually in size is different. Another option is if the axis of the arc, which indicates the course of the recesses, from the axis of rotation of the Support arm is spaced depending on the desired mode of action.

According to the invention, a particularly advantageous and structurally simple solution is if a tooth piece of the recess on the longitudinal axis of the Support arm is arranged and is smaller than the adjacent tooth pieces. This ensures that the wing in the Tilt open position automatically in an open tilt limit position  is transferred. This is made possible by the fact that the wing in Closed position by the circumferential known in the prior art Seal is slightly biased. Through the tooth piece of the support arm and the opposite locking projection of the locking means - which spring force is applied - the locking device is also in pre-stressed position. If the user switches the sash to the tilt position, it poses the wing automatically shuts off due to the seal and is eventually from the locking device, which is also switched off automatically is operated, transferred to one of the opening-limiting positions.

Structurally simple and particularly economical to manufacture and simple is mountable according to the invention, if for fastening separately trained locking means a receptacle is provided which on the extension arm or on the faceplate of the display device, for example by a introduced threaded hole forms a screw connection. Except for the Screw connections are also possible for other connections that are particularly economical. These include, for example, rest or Riveted joints.

It is particularly advantageous that the latching means has an energy store that a clamping member permanently applied spring force, which at least one Has locking projection, the locking projection depending on the location of the Issuing device with the locking recesses in operative connection. The energy accumulator determines the locking force on the one hand and the on the other Torque resistance. At the same time tolerance deviations resulting from the individual components result in balanced.

It is particularly advantageous that the clamping member is a molded plastic part. So the clamping member can be manufactured particularly inexpensively. When choosing the Plastic can be dispensed with lubrication. In general selected plastics result in a good friction and Wear behavior. As a result, the lifespan is considered to be appropriate Highly rated. Another variant is when the clamping member a corresponding preloadable element, e.g. B. is made of spring steel.  

Such a spring steel element can, for. B. with the help of additional resilient Arms replace the lift mechanism. But there are also other materials applicable.

According to a further feature of the invention, it is advantageous that the latching means is arranged between the faceplate and the extension arm. So you can realize the locking device described very space-saving and that without special reworking of the existing components of the turning Tilt fittings as well as additional rework on the window profile.

A particularly advantageous development of this embodiment provides that the locking means has an adjusting member with a tool engagement, so that the spring force of the energy accumulator is adjustable. It can Adjustment member, for example, be a screw in a housing of the Locking means is screwed in and by means of a tool intervention For example, consists of a hexagon socket, the spring force of the Force storage and thus transferable to the clamping member Limit the opening and the braking effect.

An expedient because simple and inexpensive manufacture of the Locking device is guaranteed when the locking means and the support arm can be used for all sizes of the display device. As if from a standing start is known in the art, the known support arm does not change in its Length in relation to the individual sizes of the display device that the Window sizes should cover, which means that the support arm only with the Locking recess / s is provided. The locking device is an independent one Component that can be retrofitted or directly with the display device is connected.

A particularly advantageous development of this embodiment provides that the support arm is arched at least at one end, where the axis of the arc from the actual axis of rotation of the support arm is spaced. In the closed and tilted end positions, the Window sashes have an opening-limiting effect. During the  Tipping process, d. H. in the section where the locking means the bow of the Support arm leaves, the device acts on the wing braking.

Fig. 1 of the drawing shows, as an application example of the invention, a turn-tilt window with a window frame 1. In this frame 1 a wing 2 is held on the one hand by a - not recognizable - corner bearing 3 and on the other hand by a - also not recognizable - tilting bearing 4 about a lower, horizontal axis.

With the corner bearing 3 and an upper pivot bearing 5 , however, the wing 2 can also be opened relative to the frame 1 about a lateral, vertical axis in the rotational position. The tilt-open position of the wing 2 is limited by an opening device 6 , which is held in the pivot bearing 5 on the frame 1 and can be coupled to the wing 2 to open it in a manner known per se. To lock and unlock the closed wing 2 with respect to the frame 1 for engaging and disengaging the tilting bearing 4 and also for coupling and uncoupling the opening device 6 , a connecting rod fitting 7 is installed in the wing 2 , the actuating linkage of which is actuated by an operating handle 8 via an actuating gear coupled to it 9 can be moved. The actuating linkage carries a latch 10 at the top near the pivot bearing 5 , through which the display device 6 can be coupled with this in the closed position and for pivoting opening of the leaf 2 , while for the tilt opening, as shown in FIG. 1, thereof can be uncoupled.

The deployment device 6 is supported by a stay arm and a support arm 6 a 6 b formed which are effective between the frame 1 and the wing 2 in the manner of a so-called elliptical link. For this purpose, the support arm 6 b is articulated on the one hand on the wing 2 and on the other hand on the extension arm 6 a only pivotably. The facing away from the pivot bearing 5 on the frame 1 the end of the opening arm 6 a schwenkverschieblich acts together with a longitudinal guide 11, which in Fig. 10 can be seen and is provided at the upper, horizontal wing leg.

The longitudinal guide 11 is generally formed by a so-called faceplate, which is attached to the wing 2 and on its underside holds a drive rod 12 of the actuating linkage 7 , as can be seen in FIG. 2.

With the aid of the drive rod 12 , the bolt 10 , which interacts with the opening device 6 , is adjusted, among other things. The face plate and the longitudinal guide 11 is provided with an elongated hole, engages the schwenkverschieblich a pin 14, which is fixed at the front end of the set-6 a. The rear end of the elongated hole 13 forms a limit stop 15 for the pin 14 of the extension arm 6 a, through which the largest possible tilt opening width for the wing 2 relative to the frame 1 is determined. This tilt opening width of the wing 2 is usually between 130 mm and 150 mm compared to the frame 1 . It is reached when the pin 14 of the extension arm 6 a slides within the elongated hole 13 up to its rear end and comes to rest against the stop 15 there, as is indicated in FIG. 10.

Often results in the practical use, the need for the wing 2 in relation to the frame 1 at least in the by the interaction with the extension arm 6 a and the supporting arm to fix 6 b limited Opened tilt against undesired slamming automatically. For this reason, it is desirable to arrange a special locking device 16 between the opening device 6 and the wing 2 . It is important to design them in such a way that they require a minimal installation space and can be installed and / or removed between the opening device 6 and sash 2 at any time, even subsequently. The assembly work required for this should be kept to an absolute minimum.

Fig. 2 shows a turn-tilt fitting in the region of an opening device 6 for a wing 2 , specifically a faceplate 17 to be fastened in a wing groove, on which a drive rod 12 is guided in a longitudinally displaceable manner. The support arm 6 b at the one end 20 of the extension arm 6 a is pivoted to the axis of rotation 21, has, as shown in Fig. 3, at the end 20 of locking recesses 23, which are formed tooth-shaped and transversely to the longitudinal axis 24 of the support arm 6 b are arranged and thereby form an arc 25 .

Between the faceplate 17 and the support arm 6 b or the drive rod 12 , a locking means 26 is effective, which is arranged between the faceplate 17 and the drive rod 12 and is automatically effective regardless of the actuating linkage 7 in the tilt ready position of the wing.

The latching means 26 comprises - as this is shown in particular in the top view according to FIG. 4 - a housing 27 which in this exemplary embodiment according to FIG. 3 or FIG. 4 is fastened to the extension arm 6 a by means of a threaded hole 28 with a fastening means not shown here . The extension arm 6 a has a receptacle 29 that, as shown in FIG. 2, forms a countersunk hole into which the fastening means (not shown) is immersed. In the housing 27 of the locking means 26 , a clamping member 30 is mounted, which acts permanently on the clamping member 30 via an energy store 31 . The clamping member 30 has a locking projection 32, the b through a recess 33 of the housing 27 with the locking recesses 23 of the supporting arm 6 enters into operative connection.

As can be seen from Fig. 2, 3 and Fig. 4, the window is in the closed position. In particular, the enlarged partial view of FIG. 4 of the detail W according to FIG. 3 clarifies that the support arm 6 b has a tooth piece 34 which is arranged in the closed position on the longitudinal axis of the support arm 24 and with its tip the tip of the locking projection 32 of the clamping member 30 in the pretensioned position - due to the energy accumulator 31 located in the locking means 26 - exactly opposite.

On the - not shown - circumferential seal, the wing is also in a prestressed position in the closed position. As soon as the leaf 2 is transferred by operation of the operating handle 8 through the operating rod 7 from the rotational position in the Opened tilt, moves the wing 2 in a first Kippöffnungsbegrenzung - as can be seen from Figure 5 and 6.. -. Here, the locking projection 32 latches the latching means 26 in a latching recess 23 of the supporting arm 6 b in a secure latching position as the tooth piece 34, thereby indicating by an adjacent tooth piece 35, which is designed structurally greater a greater support against further Kippöffnen.

The symmetrical structure of the support arm 6 b in the view of the locking device 16 , the locking recesses 23 of the support arm 6 b and the locking means 26 , which is also formed longitudinally symmetrical, allows use for right and left use.

In Fig. 7 another embodiment is shown, wherein the stay device 6 in one of the detent recesses 23 Kippöffnungsbegrenzungsstellungen b by the supporting arm 6 operates on the end 22 rotatably locking with the locking means 26. The locking means 26 forms a fixed connection with the faceplate 17 via a receptacle 29 .

Assuming that the support arm 6 b does not change in its design, for example in relation to the length with regard to the different sizes of the opening device 6 , and that the latching means 26 is an independent component, the locking device 16 is considered in isolation for all sizes of the Display device 6 can be used without change. Even the positioning of the receptacle 29 in the embodiment according to FIG. 5 in the extension arm 6 a or according to the embodiment according to FIG. 7, where the receptacle 29 is assigned to the faceplate 17 , can be easily dimensioned for different sizes of the deployment device 6 if one starts from the respective axes of rotation of the support arm 6 b. It can therefore be seen that the locking device 16 described, like the embodiment variants to be described, can be realized in a very space-saving manner and can be easily integrated into the normal structure of such a fitting without impairing the other functions of the turn-tilt fitting.

FIG. 8 shows the embodiment variant according to FIG. 5 in a further position limited by tilt opening, in which the transition from the position shown in FIG. 5 to the position shown in FIG. 8 represents a considerably greater locking action than the transition from the closed position according to FIG . 3 in the position according to Fig. 5. Therefore, the following pieces are respectively adjacent tooth for tooth 35 of the piece 34, which are formed substantially higher. In addition, FIG. 8 and the enlarged partial representation of the detail Y from FIG. 8 show a further exemplary embodiment of the latching means 26 , which has an adjusting element 36 which, as illustrated, additionally has the latching effect or the opening limitation via a tool engagement, for example via a hexagon socket can influence. The adjusting member 36 preferably consists of a threaded screw which is screwed into the housing 27 of the locking means 26 over a plurality of threads. The adjusting member 36 acts directly on the energy accumulator 31 , which transmits the effect on the clamping member 30 .

Fig. 10 shows the turn-tilt fitting in the full tilt opening position, wherein the pin 14 passes through the slot 13 up to the limit stop 15 and finally strikes the limit stop 15 . At the same time, the locking projection 32 of the clamping member 30 overcomes a toothed piece 35 of the support arm 6 b and finally slides on the longitudinal surface 38 of the support arm 6 b into one of the locking devices 16 predetermined end position.

A second embodiment variant of the locking device 16 is shown in FIG. 11 and in the partially enlarged representation of the detail Z from FIG. 11. In terms of construction, the latching means 26 remains unchanged in this embodiment and also the positioning on the extension arm 6 a or, for example, on the faceplate 17 . The support arm 6 b, however, has at least at one end an arc 39 , the axis 40 of which is spaced from the axis of rotation 21 of the support arm. In the position of the opening device 6 shown, the latching means 26 acts on the entire arc-shaped surface 41 in an anti-rotation or braking manner on the wing 2 .

At the transition 42 from the arcuate surface 41 formed in a running symmetrically to the longitudinal axis 24 longitudinal surface 38, the locking means 26 acts on the support arm 6 b and therefore transferable to the Ausstellvorichtung 6 Öffnungsbegrenzend.

The position described and not shown in the drawing represents the tilt opening end position of the wing 2 .
