Abstract

The deflection element has a cover rail section (23) and a coupling part (22) for a movement-transmission element of an angular guide element at both sidepieces of an angular deflection part. A lever-locking device is provided at one of the sidepieces. A sliding section protrudes into a movement path of the coupling part guided at the cover rail section. The sliding section is squeezed out by the coupling part from the movement path. The lever-locking device has a lever (50) with an arm with a latch head (20) protruding through a window (32).

Description

The invention relates to a locking device suitable for tilting / sliding sash of windows or doors. Such locking devices are used in cooperation with an on the frame to the rebate facing and fixedly arranged strike plate or closing piece to lock the wing at least in the closed position on the frame. For this purpose, the locking device itself is mounted on the casement, on a rail arranged there, cf. EP-A 249 683 (Siegenia), there figures 5, 6.

Typically, such a locking device comprises a catch as a bolt which is displaceable in a housing under the action of a biasing spring disposed therein perpendicular to the longitudinal extent of the Flügelfalzes to interlock in the extended position with the locking piece. The housing of the device is attached to a drive rod (rail), which belongs to the actuating linkage of the wing and can be operated by a handle on the wing. This means that the snap-like locking device performs together with the drive rod displacement movements in the longitudinal direction of the sash and thereby passes depending on the position of the actuating handle in different positions relative to the strike plate. For this purpose, the striking plate has various sections, to which at least one locking section and one laterally open section belong to the free passage of the catch in the strike plate. The catch has on one side a steep flank and on the other a ramp, so that it can slide back against the action of the spring when closing the open wing and when hitting the strike plate and snap behind the locking plate can get into locking engagement again.

US-A 2,810,284 (Wartian ) shows an application of a lever for a sliding door. The lever has a fixed pivot bearing (there 56 in the local FIG. 2 ) and protrudes perpendicular to the vertical extent of the vertical outer edge of the sash. It is controlled by a pivoting lever, which is pivotable between two positions and attacks two stops of the main bolt (there 58,68). The head 68 of the lever there engages lockingly into a box-shaped closing piece there, when the two sliding windows approach each other and almost touch each other. A spring element is additionally provided (there 58) and pushes the lever in the closed position (down there, in the counterclockwise direction). Also GB-A-2 168 748 (Smith ) shows transversely projecting levers, which are longitudinally movably arranged in a housing and used for locking. Also in the vertical orientation are the levers behind CH-A 325 022 (Tlach ) in the local Figures 3 and 4 , moved with an actuating rod 18, relative to the wing and limited to sliding window.

It is an object of the invention to provide a locking device which ensures a locked (closed) position and at the same time simplifies the mounting of the striker relative to a Schnäpperkopf.

This object is achieved once by the teaching of claim 1 and the other by the teaching of claim 8, which refers to claim 1.

In the solutions, the catch can be mounted immovably on the casement as a lever, in particular on a rail arranged there but not movable in the longitudinal direction (eg a cover rail), cf. Claim 2.

The catch lever (or: lever-shaped catch) is in the embodiment of the invention no longer part of the drive rod, so does not participate in the longitudinal movements of the drive rod. Rather, the catch lever can be mounted immovable, but pivotable on a cover or Stulpschienenabschnitt.

The drive rod element receives a control function for the Schwenkschnäperper (= lever-shaped catch), by bringing in certain positions the lever-shaped catch out of engagement with the closing piece or locks in the engaged position against pivoting back.

Advantageously, the lever-shaped catch (swivel catch) can be preassembled with a cover rail section and a drive rod section as a structural unit. This can be achieved particularly simply and favorably by providing the locking device as an integral part of a corner drive.

The preassembled assembly may be configured to share a portion of a drive rod and a portion of a deck rail that define therebetween a housing space that receives the lever-shaped latch. This side and beyond (seen in the longitudinal direction), the two rod sections come closer together again, which can be done via a bend. The mutual alignment and guidance as well as the measure of the distance can make intermediate pieces, which also serve to support in the groove of the wing.

At least one control member is used to control the locking device, the control being via movement of the drive rod, relative to the lever-shaped catch. For this purpose, at least one control section of the lever-shaped catch is provided, which protrudes into the sliding path of at least one control lever of the drive rod. As control elements edges or surfaces can be used, as well as other functional elements that participate in the movement of the drive rod. If a recess provided in the drive rod (claim 6), one of the control members may be a free edge. Also, two spaced free edges may be control members, for lifting the lever-shaped latch and for locking the lever-shaped latch in its outwardly pivoted position (claim 7).

Instead of an edge, an inner surface of the drive rod pointing toward the lever-shaped catch can also serve as a control member which runs on a ramp and controls the lifting movement of the lever-shaped catch in its retracted position over a portion of the drive rod movement. While the Aufgleitabschnitt is herausdrängbar of the surface portion of the drive rod from its trajectory, the longitudinally immovable lever-shaped catch is raised.

If the housing for the lever-shaped catch is provided by spaced pieces of driving rod and cover rail, then two spaced windows may be provided, one for the passage of the catch head of the lever-shaped catch and one for forming the at least one control member as an edge, two edges or in addition patch.

By the drive rod different movements or pivotal movements of the lever-shaped latch are controlled. It may be released when the one edge as a controller leaves its blocking device and moves away from the control section. The lever-shaped catch can be locked when the locking edge is in contact with the control portion of the two-armed lever, or at least at such a small distance from it, that a pivoting, which leads to a lead out of the Schnäpperkopfes from the latch pocket on the frame is locked. An active actuation of the lever-shaped latch is possible through a surface or by a combination of an edge and a surface on the drive rod, if the above-described blocking edge has reached a position in which the lever-shaped catch is released.

Further advantages are an additionally controlled active locking of the closed position and a mounting relief by a permissible greater tolerance in the alignment of the closing piece and the Schnäpperposition as the position of the non-displaceable lever-shaped latch.

The invention will be explained in more detail with reference to schematic drawings of several execution examples .

The in FIG. 1 shown fitting 1 for the wing of a window of a door has on the sash, not shown on an operating handle 2, in different positions, in the Figures 2 are reproduced, can be moved. These different positions are the closed position of the wing ( FIG. 2a ), a detent position ( FIG. 2b ) and an unlocking position ( Figure 2c ).

In the closed position, the wing is firmly locked to the frame (not shown).

In the locked position, the wing can be tilted into a ventilation position.

In the unlocked position, the wing can be turned off (pivoted) into the open position, which corresponds to a parallel shutdown, in order then to be moved parallel to the frame.

However, the invention is not only suitable for a tilt / slide wing but also for a tilt / swing wing, which is readily apparent to those skilled in the art.

The fitting shown in FIG. 1 has an actuatable by the handle 2 drive rod 3, which can be coupled via the coupling element 5a, 5 to a corner drive 4. The coupling element is at a movement of the drive rod. 3 forwarding member (at least one flexible, thrust receiving tape) in a guide housing 7 of the corner 4 in connection, which housing itself is in turn connected to a cover rail section 6. On the other leg of the corner 4, in turn, a coupling element 8,8a and a cover rail section 9 is provided. Element 8 is connected to the motion transmission element, section 9 is connected to the housing 7 of the corner drive 4. To the coupling element 8, a further connecting element 11 (with drive rail 22a and cover rail 23a, as in FIG. 4 explained later) can be coupled, which can be done via a gear coupling 8a and a laterally toothed end of a secondary drive rail. The couplings are short, the rod sections longer. Short is also the indicated closing piece 10, which cooperates with the pivoting Schnäpperkopf 20 to be described.

At the other lower corner of the fitting are the same conditions, but in mirror image.

The Figures 2 show sections of the lower horizontal leg of the corner 4 after FIG. 1 , In the Figures 2a, 2b and 2c the different positions of the lever 2 and the different corresponding positions of a Schnäpperbildbildenden member 26 are shown in the middle of the figures in side view and in the right half of the figures in a vertical section corresponding to the section lines EE and HH, and FF and GG.

In the figures, one sees an espagnolette element 22, which after the coupling element 8 of the corner 4 after FIG. 1 can correspond. Furthermore, one can see a cover rail 23 which follows the cover rail section 9 of the corner drive 4 FIG. 1 can correspond.

On the cover rail 23 guide elements 24 are fixedly mounted for the drive rod section 22 with longitudinal windows. The guide elements 24 are also designed as supports to give the structure in the groove bottom a stop when the drive rod is lowered according to the right sectional view (perpendicular to the wing plane) in the groove 21 and is covered by the cover rail. The block-shaped pieces 24, which are at least partially visible on both sides of the pivot lever 26, provide a support and a guide for the drive rail. They also maintain the distance between the cover rail and the drive rail, so that they get several functions at the same time.

The drive rod section 22 has spaced longitudinal windows 32, 35 and 37. Two of these longitudinal windows 37, 35 serve to guide the guide elements described above, while the additional longitudinal window 32 located between these windows is described below as a control window for controlling the locking lever 26.

The drive rod portion 22 and the cover rail 23 are arranged in the usual manner in the circumferential groove 21 at the fold 13 (end face) of the wing 12, in the example shown in the lower cross member. The wing is through his profile in FIG. 2a , right half, reproduced. The wing is in the closed position with the front side 13 opposite to the center of the FIG. 2a indicated frame 41 shown. In this position, the rollover 14 of the wing is sealingly on the frame. The opening direction (parking in parallel direction or turning) is represented by the arrow 15.

Between sash 13 and frame of the rebate 42 extends with the height a.

On the cover rail portion 23, the snap-type locking device is fixed immovably.

For this purpose, the device has a frame 25 which is riveted to the cover rail 23. In the frame 25, a lever-shaped member 26 is pivotally mounted as a locking lever via a transverse to the plane of the wing pivot axis 40. The so-formed "Schnapperglied" 26 has two arms 27,28. On the arm 27, a head 20 is provided in the region of the end, which, as FIG. 2b shows in the right half, on one side a steep locking edge 20a and on the opposite side has a ramp 20b and projects through a longitudinal window 38 of the cover rail 23. On the frame 41, a closing piece 10 is arranged, in which the latch head 20 in the closed position of the wing ( FIG. 2a ) as well as in the rest position or tilt position (see. FIG. 2b ) engages interlocking. Thus, the lower end of the wing is fixed relative to the frame.

By the inclined ramp surface 20b of the wing can be brought from the open position to the closed position by the catch 20 slides on the outer side 10b of the strike plate 10 and then engages in the locking piece.

For this purpose, the other arm 28 of the latch member 26 is under the biasing action of a spring 31 which is supported in the frame 25. The direction of action of the spring is such that the latch head 20 is biased in the direction of its engagement position. In the engagement position as well as in the detent position protrudes provided on the arm 28, for controlling suitable Aufgleitabschnitt 28b in the window 32 of the drive rod 22. It can be seen that in the closed position to FIG. 2a a locking edge 32a of the window 32 of the drive rod 22 on a rear end face 28a of a control section 28b of the arm 28 engages and thus prevents the Schnubpperhebel 26 from the closed position to FIG. 2a can be swung back.

This blocking function can also be more effective due to the arrangement FIG. 3 be realized. FIG. 3 shows the snapper like device in the same closed position FIG. 2a , The Schnapperglied is designated 50. The arm having the control section 51 a is denoted by 51. It has on its underside a recess which is engaged in the closed position by the edge 52a of a protruding or pointing into the window 32 portion 52 of the drive rod element 22. Neither in the execution after FIG. 2a still according to the FIG. 3 can the Schnapperglied 26 and 50 are levered out without moving the drive rod portion 22 from the closed position shown. There is an additional active (controlled) blocking.

The box-like frame 25, in which the catch member 26 is mounted, forms with the cover rail portion 23 a structural unit, preferably also with the drive rod 22, in particular when all parts are integrated in the corner assembly forming a structural unit 4. By the fixed mounting of the frame 25 on the cover rail 23, the incorporation of the device is much easier. Also, the position of the striker 10 on the frame does not have to be adapted very accurately to the position of the latch head, as is the case with the slidable snaps and the different sections of the "strike plate" adapted thereto.

When moving from the closed position to the locked position of the drive rod section 22 is made FIG. 2 to FIG. 2b moved to the right. A control edge 32b at the end of the recess 32 of the drive rod is in the locked position just before the control section 28b. Upon further displacement of the drive rod 22 to the right in the unlocked position, the edge 32b slides over the control portion 28b of the Schnappergliedes 26 away and lifts with the following web 32c thereby the Schnäpperkopf 20 against the action of the biasing spring 31 the lock pocket 10a, like this one Figure 2c shows. The wing can now be swung out or parked with sliding sashes.

When lifting the Schnäpperkopfes 20 as part of the lever 26, this pulls back through the window 38 in the cover rail 23 and engages at least partially in the window 37, which extends to the left of the web 32c. The web 32c has the area provided for the control of the other arm 28b with its Aufgleitabschnitt area facing the cover rail. In dashed lines, this movement is as 20 * (position of the head 20) also in FIG. 2b shown, wherein the web 32c has not yet been completely moved over the Aufgleitabschnitt 28b, in the direction w. The shape of the head 20 may be adapted to the shape of the frame 25 at its left end.

It should be noted that the Figures 2 are shown so that the left side to the housing 7 of the corner of FIG. 1 points while the right side to the connecting portion 11 of FIG. 1 continues. This can be seen on the thrust absorbing deflecting strip in the guide housing 7, which at the left end of Figures 2 above the cover rail 23 can be seen.

As FIG. 2a shows the rightmost, the assembly of Schnäppervorrichtung, drive rod and cover rail can be easily inserted into the circumferential profile of the sash. Only the catch head 20 protrudes in the closed position or the detent position from this groove, through the corresponding window 38 in the cover rail 23rd

The previously for a corner drive based on the FIG. 1 described design of a pivoting bolt 26 may also be realized in the course of the elongated connecting element 11 between two Eckumlenkungen, as well as in all applications where only straight pieces of drive rod 22a and cover rail 23a are used, as shown schematically FIG. 4 is explained. The pivot lever 26 has the same configuration here as on the Figures 2 explained. The drive rail 22a is longitudinally movable and has the three spaced windows as previously described. Of these windows, the window 32 is the one providing the control edges and, in the illustration shown, is substantially at the level of the window 38 through which the head 20 of the lever 26 engages so as to be able to lock behind the striker 10 with screws in the frame 41 is fixed.

The rebate is designated 42, in which the head 20 protrudes. The distance between the two rails 23a, 22a in the region of the lever 26 is h, while a reduced distance k is provided left and right of the pivot lever, which is achieved by correspondingly spaced and aligned cranks of the drive rod 22a.

The control function of the edges 32a, 32b and the lower surface of the ridge 32c are the same as on FIG. 2 explained. Also the execution of FIG. 3 is usable here.

It should be noted that the left-hand bend of FIG. 4 such a distance from the left end of the head 20 of the pivot lever 26 has that a displacement in the direction w (the sliding path of the drive rod or the associated control members) to the right is possible without the crank abuts the frame 25, the the pivot lever at least on the two axial sides, preferably also on the lateral sides, to which the two surfaces 20a, 20b show surrounds.
