Description

The invention relates to a drive rod lock for a against a frame movable wings with one in one Lock case movably arranged latch coming from one Drive rod is actuated, wherein the latch at a Movement of the drive rod from a locking position, in the bar with a latch section from the Lock case sticks out, into one inside the lock case located unlocking position is movable, the latch being biased out of the lock case is, with a locking device for holding the bolt in the unlocked position, and with one with the locking device connected, from the movement of the grand piano against the frame controllable buttons.

Such espagnolette lock is for example off DE 38 36 693 C2. Here is the button with a switching element of the locking device connected, which holds the latch in the unlocked position when the button protrudes from the lock case. In this Position, the wing is pivoted away from the frame. If you swing the wing against the frame, the button comes against a strike plate and is doing in the Lock case pressed in. The button gives the movement the switching element free, whereby the bolt of the force of the spring element out of the lock case is pressed into the locking position. To exercise the bolt back into the lock case back to the opening of the wing of the espagnolette fitting is driven. This espagnolette lock will pivot every time the wing against the frame in the locked position brought.

The disadvantage of this espagnolette lock is that too with a momentary swinging of the wing against the Frame and then removing the sash of the buttons the locking device triggers and the bolt in the Locking position is moved. This leads to the latch with the wing removed from the frame in the Locking position remains. A subsequent renewed Swinging the wing against the frame leads to a Damage to the bolt and its opposite Strike plate.

From EP 0 942 135 A1 an espagnolette lock is known become, in which the latch formed as a latch bolt is and between the unlocked position and the locking position arranged trap position having. The button is located in the latch bolt and is controlled by the movement of the latch bolt. Another disadvantage of this espagnolette lock is that already a brief movement of the wing against the Slightly push back the latch latch and As a result, the locking device is triggered. So that can here, too, the bolt with the wing removed from the frame be moved to the locking position, which again Closing the sash leads to damage.

The invention is based on the problem of a drive rod lock of the type mentioned at the beginning, that a movement of the bolt in the locked position with only short-term swinging of the wing against the Framework is largely avoided.

This problem is inventively achieved in that the locking device a second stage for supporting the Tie bar in a middle position in which the tie essentially arranged only with one at its free end Run-up slope protrudes from the lock case has.

By this design, the latch of the lock device be caught at the second stage when the Push button only briefly or only a small way at operated in unlocking befindlichem latch becomes. In this second stage, however, the bar is only with its run-on slope opposite the strike plate. First if you press the button far enough into the lock case, the second stage can be overcome and the bolt reaches the locking position. Emotional you only briefly pull the wing against the frame and pull then the wing away from the frame, is thanks to the invention of the probe only briefly or by one moved small way, and thus the bolt in the second Level of locking device caught. The second Level of locking device held latch leaves similar to swinging the sash against the frame like pushing a trap back into the lock case and stays there. This will cause a movement of the bolt in the locking position with only short-term panning of the wing against the frame avoided.

The holder of the bolt in the middle position and in the unlocked position requires according to an advantageous Development of the invention a particularly low Structural effort when the locking device with a having the latch connected control part with two stages and if a plant of the control part with the first Stage on a locking element of the unlocked position corresponds and with the second stage of the middle position equivalent.

The way the button is pressed into the lock case must be to stop the movement of the bolt in the Locking position to allow, according to another advantageous embodiment of the invention Simply set if the second stage than on the control section arranged paragraph is formed and if the Paragraph in the direction of movement of the blocking element at a movement of the button into the lock case has. The dimensions of the paragraph are thus a measure for the required movement of the button.

For a brief closing and subsequent opening the wing can be made out of the lock case moving-out latch according to another advantageous Catching the invention particularly early, if the control part between the two stages one with at least one projection of the blocking element cooperating Has toothing.

The espagnolette lock according to the invention is designed structurally particularly simple, if the control part and the bolt have a common storage.

The control of the movement of the bolt requires according to another advantageous embodiment of the invention a particularly low structural complexity, if the Slider one protruding shoulder and the latch one protruding, in the range of motion of the shoulder having penetrating control pin.

To reduce the manufacturing costs of the invention Espagnolette contributes to it when the locking element is made in one piece with the button.

The bolt could for example in one piece with the control part be made. Since the bar is usually very is massively trained to high, acting on the wing To support forces, however, requires the control part only very small dimensions. Damage to the control unit in the manufacture or assembly of the bolt can be according to another advantageous development simply avoid the invention when the control part is attached to the latch.

The guidance of the slide in the lock case requires according to another advantageous embodiment of the invention especially few components, when the slider a has elongated recess on the storage of the bolt. This contributes to the further reduction of manufacturing costs of the espagnolette lock according to the invention.

A release of the locking device exclusively at reliable lying in the frame can be according to another advantageous embodiment of the invention Just make sure the button is in the direction of movement of the wing is placed on the frame in front of the bolt is.
