Description

The Invention relates to a swivel lever actuation with safety device, comprising one on one side (outside) of a thin Wall, such as cabinet door, attachable trough, leaving the trough has at its one longitudinal end an approach whose Cross section is essentially rectangular and that of the thin Wall formed mounting plane towards the other side (inside) the thin wall pierces, and the other Longitudinal bearing a drive shaft, on which a hand lever from the trough about an axis parallel to the mounting plane swung out and optionally about an axis perpendicular to the mounting plane in the Trough is rotatably mounted, wherein from the trough / the hand lever projection Locking devices go out with complementary Interlocking devices of the hand lever projection / the trough cooperate.

Such a pivot lever operation with safety device is already out of the DE 60206687 D2 known. Furthermore, be on the DE 202007006513 U1 directed.

In both cases is an electrically extendable locking pin and a mechanically operable cylinder lock, which is suitable in case of power failure, the hand lever from the locked position find out.

Both known constructions have the disadvantage that the stability the tumbler is not optimal.

task The invention is a swivel lever operation with safety device to create, which avoids the disadvantage of the known arrangement.

The object is achieved in that two mutually independent mechanical locking devices ( 144 . 162 ) for the free end of the hand lever ( 26 ) are provided, that in the hand lever projection, a mechanical drive, such as a thumb provided with lock cylinder is arranged such that the thumb moves on actuation of the lock cylinder, the locking devices in the open / closed position, and that arranged in the trough a pin with electric drive is that upon actuation of the electric drive, the locking devices are moved to the closed / open position. This design allows an embodiment which is much more stable than in the prior art. In addition, a construction is conceivable, and also realized according to an embodiment which prevents possible rattling action with a normal closure and thus excludes existing play by spring means. In particular, according to an embodiment of the invention, the locking device comprises a slide which is displaceable against spring or gravity in a thrust bearing formed by the approach.

alternative may in place of the slider device, the locking device comprises a lever which in a lever bearing formed by the approach is pivotable against spring or gravity.

Of the Slider or the lever can be a trap-like trained end have, which facilitates the closing process.

the Slider opposite can pass through the fall-like end have a piston-like end, what the cooperation with a facilitates electrically actuated pin and improves the leadership.

Of the Slider or the lever can between a fall-like and piston-like end arranged forward or return in which the mechanical drive such as cylinder thumb engages to to move it against the spring or gravity.

Of the Slide or the lever can open at both ends or bore Have cylinder for receiving the piston and the pin.

Especially for backlash-free control, it is advantageous if, according to a another embodiment of the slide or lever next the case forming inlet sloping surface a forms an angle-forming support surface.

The Holding surface of the slider or the lever can in particular form such an angle to its direction of motion that when Unfolding the operating lever overcomes the holding forces be (snap function).

Of the Slider or the lever can be such a counter surface for Holding surface find that any movement play is absorbed by the spring or gravity effect.

Of the Slide or the lever can between two mechanical drives, like two thumb-lined cylinders.

The Invention will become apparent from exemplary embodiments explained, which are illustrated in the drawings.

1 shows a perspective view of one side (outside) of a thin wall 10 , such as cabinet door, attachable trough 12 a pivot lever operation 14 with safety device 16 , where the trough 12 at its one longitudinal end an approach 20 whose cross-section is substantially rectangular and that of the thin wall 10 formed mounting plane towards the other side (inside), see 2 and 3 pierces, and their other longitudinal end 22 a drive shaft 24 outsourced to the one hand lever 26 from the hollow 12 around an axis parallel to the mounting plane 28 swung out and in the illustrated embodiment about an axis perpendicular to the mounting plane 30 , please refer 2 in the hollow 12 is rotatably mounted, wherein of the hand lever 26 also a lead 36 emanates. From the hollow 12 or the hand lever protrusion 36 go locking devices 32 Made with complementary locking devices 34 of the hand lever protrusion 36 or the trough 12 interact.

In the hand lever projection 36 is a mechanical drive, such as thumb-lock cylinder 38 . 40 arranged such that the thumb 42 upon actuation of the lock cylinder, the locking devices are moved to the open / closed position, and that in the trough 12 a pen 44 with electric drive 46 is arranged such that upon actuation of the electric drive 46 the locking devices 32 . 34 is moved to the closed or open position.

The closed position is in 3B shown, the opened in 3A ,

The locking device 32 , includes a slider 48 which slider in one of the tab 36 of the hand lever 26 formed thrust bearing 50 is displaceable against spring or gravity. Instead of the slide, a lever may be provided which may be pivoted in a pivot bearing formed by the projection against spring or gravity.

The last embodiment is not shown.

The slider 40 (Or the lever) may have a fold-like design end, so is a closing or lever operation, which automatically enters via an inlet rail or surface.

6A shows this inlet inclined surface 152 in connection with an embodiment having only one lock cylinder.

As in 6C illustrated, the slider (or the lever) 48 . 148 opposite to the fall-like end 52 . 152 a piston-like end 54 . 154 exhibit.

The slider 48 . 148 or the lever can be one between fall-like ( 52 . 152 ) and piston-like ( 54 . 154 ) formed end arranged projection 58 . 158 or return 156 in which the mechanical drive such as cylinder thumb 42 . 142 engages to move it against the spring or gravity.

The thrust bearing 50 can be a bore 160 or cylinder for receiving the piston 154 and pen 144 exhibit.

The slider 48 . 148 (or the lever) can next to the inlet sloping surface forming the trap 52 . 152 a standing at an angle holding surface 62 . 162 form.

The holding surface 162 of the slider 148 can form such an angle to its direction of movement that the holding forces are overcome when unfolding the operating lever (Schnäpperfunktion).

The slider 150 can also be such a counter surface 164 find that any movement play is absorbed by the spring or gravity effect.

While in the embodiment according to 6A to 6C a lock cylinder 140 with a thumb 142 represents the mechanical drive is in the embodiment according to 3A to 3C the slider 48 between two mechanical drives, in the form of two cylinders with thumbs 38 . 40 arranged.

The in the 3A to 3C construction shown by a lid 66 be closed, as in 2 recognizable.

To increase the stability of the trough a support surface 70 . 170 for the pin lying near the thrust bearing.
