Description

Window or door

Technical Field

The invention relates to a window or door with a transmission rod lock, by means of which a lock bolt can be moved along a locking recess of a closing plate that is fastened in a stationary manner to a fold and that is open in the longitudinal direction of the fold, wherein at least one locking element is provided in order to prevent the transmission rod from moving back at one of the locking pins in the opening direction.

Background

Such windows are known, for example, from DE7835616U1 and disclose a locking bolt in which the closure plate is equipped with a spring element which, when the leaf is closed, is pressed back in the rotation-ready position of the catch lever lock by a locking bolt inserted into the access opening and, when the locking position is set, closes the access opening. The contact pin can act on the bent section of the spring element and release the access opening. The desired effect is thereby achieved that the locking bolt is automatically secured in the closure plate recess by means of the locking portion. Disadvantageously, this design provides only the open and locked position of the drive rod fitting. For the currently customary casement-tilt-inside wings, the known design is not used.

A locking device is known from EP0711896a2, which provides a frame-side locking joint. The locking engagement has in its locking recess a pair of hooks with a pawl thumb on which the handle of the latch comes to rest when it is inserted into the locking recess. The hook lever can be moved in the direction of movement of the locking element and is carried along by the locking element over a partial stroke. The movement of the hooks causes pivoting of the hooks and these hooks enclose the shank of the lock with fingers. The latch is thereby received in the undercut of the finger. In addition to the high number of individual parts in the form of small pieces, this design offers only a small safety benefit, since no reaction is made to the drive lever in order to move it into the flat-open position. Furthermore, in addition to the operating force of the transmission rod fitting, the spring force must also be overcome.

A closure device is known from EP2312103a2, which is suitable for the horizontal opening of a tilt-in window and whose closure plate is provided with a slider that can be moved along a locking pin. Starting from the flat-open position, the slider is moved together into the locking position by the locking pin in such a way that the locking pin inlet and outlet and the recess in the slider overlap one another, since the slider is moved together in the corresponding direction by the locking pin. If the drive rod fitting is placed in its inner, inverted open position, the locking pin guides the slider with it and the locking edges of the slider close the locking pin inlet and outlet. The driver rod fitting can thus be brought from the inverted position into the flat open position. When the plunger reaches the rotation-ready position, the plunger is located in front of the striker pin inlet and outlet, which are closed by the slider. Therefore, the locking position must first be occupied in order to move the slide into its unactivated release position. There is therefore no additional safety, since the locking bolt always presses the slide into its release position in its locking position.

It has already been proposed by DE3520861a1 that the safety of the transmission rod fitting is improved by means of a counterpressure lock. In this case, a coupling position of the two drive rod sections is provided at the drive rod. A coupling member and a spring lock are arranged at the rear second transmission rod. The coupling member may be slightly movable relative to the first transfer lever. The first, previously running, transmission lever is therefore displaced over a small distance and acts on the spring catch underneath, so that the spring catch is prevented from engaging in the recess of the stationary flanged rail. If the lagging second transmission lever (which carries the locking element) is moved in the event of attempted destruction, the second transmission lever which was moved later in normal operation is moved in front of the first transmission lever and the locking spring engages and locks the second transmission lever. This design is elaborate and the relative movement of the transmission rod presupposes the use of six components with precise fit.

Disclosure of Invention

The object of the invention is therefore to provide a window design in which the locking device is of simple construction, has a reliable and loadable design and can be retrofitted independently of the type of fitting.

In order to solve this problem, the invention provides that the locking device comprises a locking lever which is mounted on the fold and points with its free end toward the locking recess and, in the first position, prevents the locking bolt from coming out of the locking recess and, in the second position, releases the locking recess.

Detailed Description

Fig. 1 to 3 show only the drive rod fitting 1 of the wing. A closure plate 3 and a locking device 4 are mounted on the frame 2. In this embodiment, the transmission rod fitting 1 has a flanged rail 5 and a transmission rod 6. The

locking bolts

7, 8 are mounted on the transmission rod 6 and pass through the flanged rail 5 with a long hole. The

latches

7, 8 can thus be moved along the fold 9 by means of the transmission rod 6. The locking device 4 is associated with an actuating element 10.

In fig. 1, the transmission rod fitting 1 is in the rotation-ready position, that is to say the

latches

7, 8 are disengaged from the closure plate 3. In this switching position, the wing can be opened flat about a vertical lateral axis. For this purpose, the frame 2 and the wing are connected to each other by suitable hinges and swing-out devices. In fig. 1, the locking device 4 is deactivated and remains without influence on the transmission rod fitting.

In fig. 2, the transmission rod fitting 1 is transferred from the position shown in fig. 1 into the locking position. The latches 8 engage into the closure plate 3 and thereby fix the wing relative to the frame 2. The locking device 4 is also shown here in the deactivated position.

If the locking device 4 is activated and assumes the position shown in fig. 3, the locking lever 11 is pivoted and points with its free end toward the closure plate 3.

This fact is explained below with the aid of fig. 4 to 7.

In fig. 4, the positions of the latch 8, the closure plate 3 and the locking device 4 are obtained when the wing is closed, that is to say the wing is swung into the frame 2 and the wing and the frame 2 occupy a position in which the planes are parallel. When the wing is closed, the blocking bolt 8 bears against the blocking lever 11 and pivots it. The locking lever 11 is supported pivotably on the plate 12 and points with its free end 13 in the direction of the closing plate 3. The blocking lever 11 is rotatably hinged to the plate 12 by means of a shoulder rivet (Bundniet) 30. A stop edge 14 is provided on the locking lever 11, with which the angle of rotation is limited counterclockwise in the drawing on a stop 15 of the plate 12. The actuating attachment 16 defines the stop edge 14 and is located on a longitudinal center axis 17 of the actuating element 10. When the driver rod fitting 1 is moved into the retracted position, the resilient edge 18 forms a recess for the locking bolt 8. The free end 13 is tapered so that the locking lever 11 does not project beyond the outer edge 19 of the closure plate 3 and thus exceeds the fold width in the pivoted-out state. The locking pin 8 is now located in front of the locking recess 20 of the closure plate 3.

If the driver fitting 1 is now actuated, the locking bolt 8 moves to the right in fig. 4 and comes to rest against the edge 18. Due to the large radius and the inclined ramp 21, the latch 8 can be returned from its inner position to the flat-open position (fig. 4).

If the transmission rod fitting 1 is brought into the locked position, the association shown in fig. 5 results. The blocking bolt 8 is inserted into the locking recess 20 and thereby releases the blocking lever 11. The locking lever is pressed against the stop 15 in the counterclockwise direction in the drawing by the force of the spring 22 (fig. 9). The locking lever is now located with its free end 13 in front of the locking recess 20. If an attempted destruction is now made, which attempts to move the transmission rod fitting 1 in its opening direction, the blocking bolt 8 strikes against the blocking lever 11 and cannot be moved any further. The latches 7 at other positions of the window are likewise not movable, since they are all connected by the transmission rod 6, so that the attempt fails.

The normal operation of the transmission rod fitting 1 also fails, since the blocking lever 11 cannot be bypassed as a result. The locking device 4 is therefore also suitable for windows in which the opening of the wing is to be carried out only by a supervisor.

In order to be able to operate the window or door again normally, the locking device 4 must be deactivated by the actuating element 10. As can be seen from fig. 10 and 11, the actuating element 10 is essentially formed by a sleeve 23 and a pin 24 which is movably mounted in the sleeve. The pin 24 is displaceable in the sleeve 23 along the longitudinal mid-axis 17 and is loaded by a spring 25 on a shoulder 26. An internally threaded locking sleeve 27 completes the operating element 10 and allows fastening in a hole 29 of the wing. The spring 25 presses the pin 24 into the active position of the locking device 4 at all times. Due to the described design, the bolt 24, when it is actuated, strikes the actuating fitting 16 of the locking lever 11 and pivots it, so that the free end 13 releases the opening area of the locking recess 20 and the locking bolt 8 can be moved out of the locking recess 20 by actuating the transmission lever fitting 1. It is therefore necessary to actuate the transmission rod fitting 1 and the operating element 10 synchronously with one another in order to bring the transmission rod fitting 1 into the flat-open opening position and open the wing. The position of the component shown in fig. 7 is derived here.

Fig. 8 and 9 show the locking device 4 in more detail. The locking lever 11 is designed as a flat plate and can be produced cost-effectively by stamping. A shoulder rivet 30 passes through the locking lever 11 and a spring 22, which is embodied as a torsion coil spring, which is accommodated in a recess 28 of the plate 12 below the locking lever 11. The spring 22 extends with a bent arm through the locking lever 11 in the bore 29.

In the embodiment shown in fig. 12, the actuating attachment 16 is displaced in its plane relative to the plane of the locking lever. This may be necessary, for example, in order to be able to arrange the actuating element 10 further away from the fold 9 and flexibly maintain the dimension 31.

The embodiment shown in fig. 12 shows a peg 32, which is fixed in the hole. The pins 32 can be adapted to different profile types and thus take into account different dimensions 31, depending on the desired length. A hole is introduced into the flange 9, which receives the pin 32 over its entire length and ensures its mobility in the required dimensions. The bolt 32 can also be a screw which is assigned to the locking lever 11 in a threaded bore.

In the exemplary embodiment shown in fig. 13, the locking lever 11 is embodied in one piece with the feeler arm 33, and the feeler arm 33 projects into the already mentioned hole in the fold 9.

The embodiments shown in fig. 12 and 13 work in a manner corresponding to the embodiments described at the outset.

The actuating element 10 is embodied here as a rectangular pushbutton, which is formed by a housing 34 and a keypad 35. The key sheet 35 is passed through a pin projecting from the bottom of the housing by means of a cylindrical pin 36, which is inserted together with two positioning pins 37 into holes in the visible face 38 of the frame.

Coil springs act between the key sheet 35 and the case 34, and urge the key sheet 35 to the retracted position of the pins 36, respectively.

Fig. 16 shows that the key plate 35 is guided on the narrow side in the housing by means of the pin 36 and two latching tabs. The actuating element 10 according to fig. 14 and 16 can be fastened by means of fastening screws which are accessible without the keypad 35 being mounted and which pass through the positioning pins 37. Alternatively, the detent pin 37 may be configured as a detent pin that snaps behind the wall of the jamb frame profile.

It can also be provided that the hole in the fold 9 is lined with a sleeve and that this sleeve is implemented additionally or as part of the plate 12.
