Description

The present invention relates to a device for locking a shutter or door shutter, which is pivotally mounted on one side of a soffit of a building about a vertical axis, in a closed position, in a fully open position and in intermediate positions can be locked, which device a equipped with a bending two-armed lever whose end portion of the one leg is pivotally mounted in a mounted on the side of the soffit storage device about a vertical axis, and its end portion of the other leg slidably guided in an attached to the shutter or door shutter substantially perpendicular to the vertical axis slide rail is mounted and can be locked by means of a locking device in the different positions.

Such devices serve to bring shutters or shutters with the simplest possible operation of a closed locked position in an open also locked position or in locked intermediate positions. The respective positions which the shutter can assume should be secured and locked so far that they can withstand, for example, strong gusts of wind. In addition, the lock should be free of play, so that moving the shutter and especially resulting from noise developments are avoidable.

Such a locking device for shutters is for example from the EP-A 1 905 929 known. This device is very easy to use, but the disadvantage of this device is that the fully open shutter tends because of the leverage ratios to be able to perform low movements in gusts, resulting in a corresponding noise development result, which is distracting.

The object of the present invention is thus to make a device for locking a shutter so that a virtually play-free locking of the shutter is possible in any position, whereby noise-developing movements of the shutter can be avoided.

According to the invention, this object is achieved in that on the side of the soffit in the region of the storage device, a locking device is attached, with which the two-legged lever in the fully open position of the shutter or door lock can be locked and unlocked for closing or partial closing of the shutter or door shutter ,

With this inventive embodiment of the present device is achieved that the two-legged lever is completely blocked in the fully open state of the shutter, moving the shutter with the resulting disadvantages is thereby avoided.

Advantageously, the locking device is formed from a bolt which is held displaceable in the bearing device substantially parallel to the vertical axis and which is equipped with a hook which engages in a corresponding recess in one leg of the two-legged lever to its locking. The design of the locking device and the arrangement in the storage device allow a simple construction and easy installation of this device.

Advantageously, at least one stop surface is attached to one leg, which comes into abutment in the locked state of the two-legged lever on a corresponding surface of the bearing device. As a result, a backlash-free locking can be achieved, in particular if the hook is additionally provided with an oblique effective surface, this backlash-free locking is ensured.

A further advantageous embodiment of the present invention is that the bearing device is formed from a rail, which comprises two webs arranged parallel to one another, between which the two-armed lever is pivotally mounted about a vertical axis forming the bearing pin, which bearing pin is inserted into corresponding holes which are arranged on the two webs. This results in a very simple embodiment of the storage device, which can be produced inexpensively.

Advantageously, a plurality of bores are mounted on the webs of the bearing device, which have a distance from each other, and are mounted in the two-armed lever a plurality of recesses having a mutual distance of the holes corresponding distance. Thereby, the position of the mounting of the two-legged lever to the rail, which is attached to the side of the soffit, can be optimally adapted to the needs, for example to different distances of the shutters of the wall of the building.

A further advantageous embodiment of the invention is that the end portion of the other leg is equipped with a head having a pin, which is slidably mounted in the slide in a linear guide, which linear guide is provided with a plurality of recesses, in which the head is lowered in each case and the end portion of the other leg of the lever locked with respect to the slide rail. As a result, the lock can be performed in a simple manner, for locking or releasing the locking of the head in the recesses of the linear guide, this can be raised or lowered accordingly by means of the other leg of the lever.

In order to avoid that in the locked state, the head can automatically lift off from the recess, a pivot bolt is advantageously attached to the end portion of the other leg, with which the inserted into the recess position of the head can be locked. This avoids unwanted opening of the shutter from the outside, this lock thus also serves as a burglar alarm.

A further advantageous embodiment of the invention is that in the slide an additional rail is inserted, and that the plurality of recesses, in which the head of the pin is lowered, are mounted in the additional rail. By simply replacing this additional rail thus different positions of the shutter can be selected in a simple manner in the corresponding device.

Advantageously, the additional rail can be positioned and locked within the slide rail. As a result, the closed position for the shutter can be set exactly in the simplest way, the installation of the slide on the shutter is thus very easy.

In an advantageous manner, a clamping screw is used for locking this additional rail in the slide rail in the additional rail, by means of which the additional rail with respect. The slide rail can be locked in an adjustable position. This makes it possible to achieve a very simple and inexpensive construction of this locking device.

An embodiment of the inventive device for locking a shutter will be explained in more detail by way of example with reference to the accompanying drawings.

Out Fig. 1 is a shutter 1 can be seen, which is mounted in a known manner on one side of a soffit 2 about a vertical axis 3 pivotally. This shutter 1 is in the fully open position and is held in this position by the device 4 for locking this shutter 1. This device 4 consists of a bearing device 5, which is attached to the side 2 of the soffit. In this bearing device 5 a zweischenkliger lever 6 is pivotally mounted about a vertical axis 7. This lever 6 has two legs 8 and 9, which is a leg 8 is held with its end in the storage device 5, the other leg 9 is slidably guided in a mounted on the shutter 1 slide 10 and by means of a locking device 11, the later described in detail, lockable. The two-leg lever 6 is provided with a bend 12, so that one leg 8 is approximately perpendicular to the other leg 9.

On the bearing device 5, a locking device 13 is attached. With this locking device 13, which will be described in detail later, the two-leg lever 6 in the fully open position of the shutter 1, as shown in FIG Fig. 1 is illustrated, are locked so that the two-legged lever 6 is fixed in the storage device 5. By this fixed two-leg lever 6, the shutter 1 is held in the fully open position.

To move the shutter 1 from the fully open position Fig. 1 to bring into the closed position, as in Fig. 2 is shown, the locking device 13 is released. The two-legged lever 6 is thereby released and can be pivoted about the vertical axis 7. The end portion of the other leg 9 is, with unlocked locking device 11, displaceable along the slide rail 10, the shutter 1 can thus be brought into the closed position in which it is held by locking the locking device 11.

How out Fig. 3 it can be seen, the bearing device 5 consists of a rail 14 which is equipped with two parallel webs 15 and 16. Between these two webs 15 and 16 of the two-armed lever 6 is pivotally mounted about a bearing pin 17 which forms the vertical axis 7, and which is inserted in corresponding bores which are mounted in the two webs 15 and 16.

The locking device 13 comprises a latch 18, which is held in corresponding recesses 19, which are attached to the two webs 15 and 16, displaceable parallel to the vertical axis 7. As will be seen later, the latch 18 is provided with a hook which can be suspended in recesses 20 which are mounted in one leg 8 of the two-legged lever 6.

At the end of the other leg 9 of the two-legged lever 6, a pin 21 is mounted, which protrudes from below into the downwardly open slide rail 10. In this slide rail 10, the recesses 22 are visible, in which the pin 21 can engage, whereby the shutter is held in the appropriate position, as will be described in more detail later.

Fig. 4 shows the two-legged lever 6, the end portion of the one leg 8 is pivotally mounted in the bearing means 5 about the pivot pin 17. In the two webs a plurality of holes 23 are mounted, which have a certain distance from each other. The bearing pin 17 can be inserted into any of these holes 23, whereby the distance of the storage of the two-legged lever can be adjusted for example from the vertical axis 3 of the shutter 1. In the bearing device 5 slidably held latch 18 locks the two-legged lever 6 by snapping into a recess 20. On this two-leg lever 6, a plurality of recesses 20 are correspondingly mounted, which have the same distance from each other, as the holes 23, the latch 18 latches thus in one of these recesses 20, depending on which of the holes 23 of the bearing pin 17 is inserted.

While in Fig. 4 the shutter is shown in the fully closed position, shows Fig. 5 the shutter 1 in the fully open position. The two-leg lever 6 is latched into the latch 18 and thus blocked, the locking device 11 is in the unlocked position, the shutter 1 is held by the blocked by the locking device 13 two-leg lever 6.

Out Fig. 6 are the individual elements visible from which the device 4 is composed. The bearing device 5 is fastened by screws 24 on the side of the soffit 2, in this bearing device 5, the bolt 18 is inserted, in the bearing device 5, the end portion of the one leg 8 is pivotally mounted, at the end of the other Leg 9, the pin 21 is inserted, also a pivot bolt 25 is provided.

The slide rail 10 is attached via end pieces 26, which are partially inserted into the slide rail 10, the shutter 1 via screw. In the slide rail 10, an additional rail 27 is inserted, whose function will be described later.

Fig. 7 shows a sectional view of the locking device. Obvious here is the rail 14 of the bearing device 5, which is equipped with the two webs 15 and 16. Between these two webs 15 and 16 of the two-legged lever 6 comes to rest, which is pivotable about the bearing pin 17. The rail 14 is attached to the side 28 of the soffit 2. In corresponding recesses 19 in the webs 15 and 16, the bolt 18 is inserted vertically displaceable. This latch 18 is equipped with a hook 29, which in the locked state of the two-armed lever 6, as in this Fig. 7 is shown, engages in the recess 20 of the two-legged lever 6. The locking surface 30 of the hook 29 is slightly beveled, whereby the two-leg lever 6, which is supported with a stop surface 31 on a corresponding surface 32 of the rail 14 of the bearing device 5, can be kept completely free of play and thereby moving the shutter in this locked state impossible.

The latch 18 falls by its own weight in the locked position, as in Fig. 7 of course, this latch 18 could be additionally biased with a spring which pushes the latch 18 in the locked position. When retracting the two-armed lever 6 in the locking device 13, the bolt 18 is raised automatically via the corresponding tapered surface 33, when the recess 20 is reached, the bolt 18 moves downward, the locked position is reached.

To unlock the locking device 13 and thus to close the shutter will, as from Fig. 8 it can be seen, the latch 18 is raised, the hook 29 moves out of the recess 20 of the two-legged Lever 6 off, this is released, the two-legged lever 6 can be extended from the locking device 13, the latch 18 can be released, he shifts back into the closed position, which is fixed in a known manner by a stop, not shown.

Out Fig. 9 the slide rail 10 can be seen. This slide rail 10, which may consist of a suitably drawn aluminum profile is, as already mentioned, attached to the shutter 1. This slide rail 10 has an open longitudinal slot 34 on the lower side. Through this open longitudinal slot 34 projects a head 35 which is formed on the pin 21, which pin 21 at the end of the other leg 9 (FIG. Fig. 3 ) is attached. In the slide rail 10, the additional rail 27 is inserted, which may also consist of an aluminum profile, which is guided in the slide rail 10 on one side. The lower part of this additional rail 27 forms a linear guide 36, along which the pin 21 is guided and the head 35 is supported. In the linear guide 36 of the additional rail 27 a plurality of recesses 22 are formed. When the pin 21 passes during movement of the shutter and the displacement of the two-legged lever 6 along this slide rail 10 in a recess 22, the pin, as will be described later, can be lowered, the head 35 enters this recess 22, the corresponding position is thus locked.

Fig. 10 shows the additional rail 27, which is retracted into the slide rail 10. The additional rail 27 can be adjusted in the slide rail 10 so that, when the head 35 of the pin 21 is in a recess 22, the shutter is in the fully closed position. In this position, the additional rail 27 can be fixed by tightening a clamping screw 37 with respect to the slide rail 10. As a result, the closed position of the shutter 1 with already mounted device 4 can be adjusted in a simple manner exactly.

In Fig. 11 is the slide 10 can be seen, which is attached to the shutter 1. The additional rail 27 is inserted into this slide rail 10, was adjusted, the clamping screw 37 is screwed tight. The pin 21, which is mounted on the two-leg lever 6, is in the raised state, the head 35 is located above the linear guide 36 of the additional rail 27. In this position, the pin 21 with the head 35 along the slide rail 10 and of the additional rail 27 in the longitudinal direction, the shutter 1 can be opened and closed.

When the pin 21 with the head 35 molded onto it, when displaced along the slide rail 10 or the additional rail 27, a recess 22 mounted in the additional rail 27 (see, for example, FIG Fig. 10 ), the pin 21 can be lowered with the head 35, as is made Fig. 12 is apparent. The head 35 thereby penetrates into the recess 22, the head 35 is thereby held in the recess 22, a displacement is no longer possible, the shutter 1 is locked in this position. The lowering of the pin 21 with the head 35 is achieved in that the end portion of the other leg 9 of the two-legged lever 6 is slightly pushed down, which is made possible by an elastic deformation of the two-legged lever 6. In order to avoid that the pin 21 and thus the head 35 can be pushed too far down, a shoulder 38 is mounted on the slide rail 10, on which the head 35 abuts.

In order to obtain a play-free locking of the shutter 1, the lower part of the pin 21, which penetrates into the corresponding recess 22, a tapered surface 39. As a result, an optimum fit can be achieved between the head 35 and the recess 22.

To the pin 21 with the molded-on head 35 in this in Fig. 12 To be able to secure shown locked position, a pivot bolt 40 is attached to the other leg 9 of the two-legged lever 6. This pivot bolt 40 can be pivoted about the axis of rotation 41 with respect to the other leg 9, in the secured state, as in Fig. 12 is shown, the one edge 42 of the pivot bolt 40 pushes between the surface of the other leg 9 of the two-legged lever 6 and the lower end of the slide rail 10, thereby avoiding that Other leg 9 of the two-legged lever 6 can be raised and thus the pin 21 can be extended with the molded-on head 35 from the recess 22.

When the lock is to be released, the pivot bolt 40 is rotated about the pivot axis 41, the flank 42 of this pivot bolt 40 releases the space between the other leg 9 of the two-armed lever 6 and the slide rail 10, as is clear Fig. 11 it can be seen, the other leg 9 of the two-armed lever 6 can be raised, the head 35 of the pin 21 thus moves out of the recess 22, the shutter 1 can be moved to another position and locked there again accordingly.

Advantageously, the recesses 22 are arranged on the additional rail 27 in the slide rail 10 so that you can set different positions between the half-open position of the shutter and the fully closed position of the shutter, more open positions are less useful, also yes fixed the fully open position of the shutter by the locking device.

This device 4 can be attached to virtually any height on the shutter or soffit, an ideal height for operability is about 30 to 40 cm above the window sill, in this position, flower pots and the like can be arranged on the window sill, one So here is completely free. It is advantageous to mount the device with respect to the height in a central region of the shutter, thereby obtaining an optimal locking and locking.

The device has been shown in the present embodiment for shutters. Of course, this device can also be used for corresponding door shutters or the like.

With this invention, an optimal device for locking a shutter is obtained, which is locked and locked without play both in the fully open position and in intermediate positions and a fully closed position. As a result, in addition to the simple operation is avoided that the shutter can move in gusts and a corresponding noise emission would arise.
