Abstract

An actuating lever (12) that can be locked in a pivoted-in position in a recess (10), one or two half-cylinders (in the case of single or double pivoting levers) being accommodated in the actuating lever (12) for locking purposes, and a locking latch (16) that can be displaced parallel to the extension of the lever which interacts with the thumb of the cylinder or cylinders in such a way that when the actuating lever (12) is moved into the pivoted-in position, a catch surface (38) of the catch (16) becomes effective, which moves the catch (16) from a locking position against Spring force pushes it into an unlocking position and then allows it to return to the locking position, characterized in that the latch surface (38) comprises a step or contour (18) which prevents the movement of the locking latch (16) into the pivoted-in locking position and blocks it in an intermediate position , and only releases it again when the locking catch (16) is pulled back with one of the two half-cylinders to such an extent that the step or contour (18) is overcome.

Description

The invention relates to an actuating lever that can be locked in a trough in the pivoted-in position, with one or two half-cylinders (in the case of single or double pivoting lever operation) to lock the actuating lever, and a locking catch that can be moved parallel to the extension of the lever is provided, which can be pushed with the thumb of the cylinder or the Cylinder interacts in such a way that upon movement of the pivoted lever into the pivoted-in position, a case surface of the locking catch becomes effective, which presses the locking catch from a locking position against spring force into an unlocking position and then allows it to return to the locking position.

Such an operating lever is already known.

The well-known swivel lever closes and locks automatically when swiveled in.

Furthermore, from the DE 32 43 029 A1 , the DE 20 2004 001 163 U1 and the DE 299 09 816 U1 lockable pivoted lever locks by means of a profile cylinder lock.

The object of the invention is to create an actuating lever which has a safeguard against unintentional locking of the pivoted lever using a mechanical solution.

The object is achieved in that the latch surface includes a step or contour that blocks the movement of the locking catch into the locking position and only releases it again when the locking catch is pulled back with one of the two half-cylinders to such an extent that the step or contour is overcome.

According to a development of the invention, the step or contour is formed in a slide which is arranged between two half-cylinders and has lateral indentations or openings into which the thumbs of the half-cylinder engage.

According to yet another development, the slider is linked to a sensor that detects the position of the slider.

According to yet another embodiment, the slide is supported in an intermediate position with a lower edge on an edge region of the trough in order to prevent the actuation from snapping into the trough.

Alternatively, the slide can be supported in the intermediate position with a recessed surface on an edge area of the trough.

The invention is explained in more detail using exemplary embodiments which are illustrated in the drawings.

It shows 1A an actuating lever 12 that can be locked in a recess 10 in a pivoted-in position, as shown, with the actuating lever 12 housing one or here two half cylinders 14 (only the receiving space for the cylinder is shown in each case), with a locking catch 16 that can be displaced parallel to the extension of the lever is provided, which interacts with the thumb of the cylinder or cylinders in such a way that when the actuating lever or pivoted lever 12 is moved into the pivoted-in position, a catch surface 16 of the locking catch becomes effective, which presses the locking catch 16 from a locking position against spring force into an unlocking position and then back into the lock position, the catch surface including a step 18 or contour which facilitates movement of the locking catch to the pivoted locked position as shown in FIG 1B shown, prevented and in an intermediate position, as in 1D or 1C is shown, blocked and only released again when the locking catch is pulled back with one of the two half-cylinders to such an extent that the step is overcome.

The stage can be formed in a slider, with the reference number 16, according to 1A is arranged between two half-cylinders 14 and has lateral depressions or openings 20 into which the thumbs of the half-cylinder engage.

The step 18 is formed in a slider 20 which lies between two half-cylinders, see the two half-cylinder receiving spaces 14, the half-cylinder not being shown, and has lateral depressions or perforations 20 into which the thumbs of the half-cylinders engage and along the slider can shift its axis.

In the illustrated embodiment, the slide 22 is provided with a piston-like drive 24 which can be driven by an electromagnetic drive, not shown.

The slider can also be linked to a sensor that detects the position of the slider and transmits it to a control device, also not shown.

In the intermediate position in the 1C is shown, the slide 22 can be supported with a projection 30 of the recess surface on an edge region 28 of the trough 10 .

Alternatively, the slide 122 can also be in the intermediate position, see 1D , Support with a lower edge 130 on the edge area of the trough.

Moreover, it should be noted that the trough 10 according to 1A for mounting on a thin wall, can be inserted through two openings arranged in the thin wall, namely with the projections 32 and 34, the projection 32 also accommodating or forming the bearing for the pivoting lever 12 and having an external thread which is equipped with a union nut to fix the trough 10 on a door leaf, not shown, while the projection 34 includes the receptacle for the area of the pivoted lever 12 that has the slider 22 and here also by means of a screw connection, for example through a cap, which can be accommodated by means of screws that can be accommodated in screw holes 36 can be put on and also holds the trough on the door leaf.

The slider 22, which represents the closure 16 and in 1F , 1G , 1H 1, has the trap surface 38, which forms a step at 18, with a return surface 30, which is shown in FIG 1D in the intermediate position is supported on the edge region 28 of the trough 10.

1E shows for the first embodiment and 2C for the second embodiment, the respective free end of the pivoting lever 12, just before the closed position.

2A and 2 B shows the same arrangement as that 1A , 1B , but in 2A and 2 B a slightly different looking slider that goes into the 2D , 2E and 2F shown is arranged. The alternative slider according to 2A and 2 B is in the 2D , 2E , 2F reproduced, the slider of the 1A , 1B in the 1D , 1E , 1F .
