Definitions
- the DE 4436513 B4 shows a device according to the preamble of claim 1.
- This known device provides an energy storage device that can be charged by pivoting the door and a force transmission means which acts on a bolt with the energy storage device. When the door is completely closed, the bolt should extend into a frame-side strike plate as a result of a force release from the energy store.
- the coupling consists of several balls which, in a first position, engage in a circumferential groove of a rod that is drive-connected to the drive rod and can be guided out of the circumferential groove against a spring force, and in a second position with the housing section, which receives the balls, dips into a flange that a disengagement of the balls does not allow.
- the automatic lock is used to lock a sash pivoted on a frame and has several bolts.
- the bolts can be controlled via a drive rod, which can be moved by means of the lever or a cylinder.
- the drive rod is assigned an energy storage device, which acts on a locking mechanism in a first functional state - the unlocked position in a second functional state - the locked position - in a shifting manner.
- a trigger element is provided on a connecting rod slide, which is effective in the unlocked position and maintains the first functional state until the sash and the frame assume a position parallel to each other. Then the release element is actuated and releases the locking mechanism and this moves into the second functional position. All of the bolts connected to the connecting rod slide and the connecting rods thereby move into the locking position.
- the energy storage device in the form of a spring is recharged when the door is opened using the handle or the key and cylinder. This requires a certain amount of force on the part of the user and a corresponding design of the drive mechanism that has to charge the energy storage device. There is therefore a desire for a simple charging of the generic device without great operating forces.
- the invention provides the features of claim 1 as a solution.
- the implementation of the features means that the energy storage device is charged when the sash is closed. The actuation therefore allows the entire leaf width to be used as a lever arm.
- the energy storage element can therefore be dimensioned sufficiently strong and the locking elements are moved into the locking engagement elements with greater force. Since the energy storage device is charged without operating the lock, the lock can be designed for the lower operating forces in terms of material and design.
- buttons with a driver form a second clutch which, when the accumulator spring is fully tensioned, separates the scissor kinematics and the energy storage mechanism from one another. This avoids possible constraints from the scissor kinematics.
- the fixation can be designed in that a housing is provided with a first slider which is displaceable relative to the energy storage device and which engages with a pin with a ramp on a wedge surface of a clamping head of the energy storage device, the locking pin in a latching recess of the energy storage device when the energy storage device is fully tensioned Housing engages and sets the slider relative to the housing.
- This configuration only requires simple components and the accumulator spring is held in the tensioned state.
- a non-positive coupling can be achieved in that the coupling has a second slider, which is guided in the housing and is in pressure connection with the first slider against the force of the energy accumulator and has a driver which is assigned to the button with a wedge surface, with the button engages the wedge surface of the driver and the wedge surface forms a ramp which moves the driver out of the displacement range of the button, and a spring effectively engages the ramp, which forces the ramp into the displacement range.
- the accumulator spring and the couplings are accommodated in an essentially tubular housing.
- the Fig.1 shows a clamping device 1 for a handle-operated automatic lock, as shown in FIG DE 202013009023 U1 known, but the clamping device can also be used for automatic locks.
- the bolts of the secondary locks are locked back and forth via the connecting rod.
- the bolt of the main lock is locked back and forth via the cylinder.
- the slider is displaced along the sash when the sash is closed via an extension arm, not shown here, which is rotatably mounted on the frame at a distance from the pivot axis of the sash.
- the path that the glider covers is a result of the different pivot points of the extension arm on the frame and the sash-side pivoting slide bearing on the glider. If the sash comes to rest on the frame, the extension arm and the glider are in an extended position. The slider is shifted in the direction of the front wing edge remote from the axis of rotation.
- the button 3 is firmly connected to the slider.
- FIG. 2 details of the structure of the clamping device 1 are shown.
- a first slider 4 is guided in a longitudinally displaceable manner in the essentially tubular housing 2 with a rectangular cross section.
- the slider 4 is designed as a sleeve 4 'and accommodates a trigger 5 in a displaceable manner.
- the trigger 5 is acted upon by the accumulator spring 6, which is supported on an abutment 7.
- the abutment 7 is slidably mounted in the housing 2 and, with a sleeve 8, extends through the inside diameter of the storage spring 6.
- a trigger tail 9 of the trigger 5 is slidably mounted.
- the trigger 5 has a ramp 10 which, with its surface inclined to the normal 11, is assigned to a roof-like tip 12 of a pin 13.
- the tip 12 and the ramp 10 have corresponding inclinations, so that the tip 12 rests on the ramp 10 over its entire length.
- the pin 13 is supported by a spring 14 against the sleeve 4 ′ of the slider 4.
- the pin 13 penetrates a bore 15 in the sleeve 4 'with a collar.
- a second bore 16 running coaxially thereto in the housing 2 is located at the point at which the bore 15 of the sleeve 4 'is when the storage spring 6 is almost completely tensioned.
- a second slider 20 is also slidably mounted in the housing 2 and abuts the slider 4 with the cover 21. As a result, the two sliders 4, 20 are only connected in the pressure direction.
- the second slider 20 is cup-shaped and the lid closes the hollow body at one end.
- the button 3 protrudes with its wedge-shaped end 22 into the slider 20.
- a driver 23 is provided in the slider 20 and is fastened in the slider 20 to the wall 25 with a bolt 24.
- the driver 23 and the button 3 lie against one another with ramps 26, 27.
- the driver 23 can be displaced along the bolt 24 or the driver 23 and the bolt 24 are fixedly attached to one another and the bolt 24 is mounted in the wall 25 so as to be displaceable. In any case, the driver 23 can be moved axially relative to the bolt 24.
- a spring 28 acts in each case on the driver 23 in the displacement area of the button 3. This lies in the direction of the bolt 24 diametrically to accommodate the bolt 24 in the wall 25.
- the driver 23 and the button 3 form via the ramps 26, 27, which allow sliding past each other, a second coupling.
- the accumulator spring 6 is tensioned to the maximum.
- the abutment 7 is held in position by the drive rod in the locking device.
- the pin 13 engages in the bore 15 in this position.
- the resulting mode of action is as follows: If the wing is closed from the rotary opening position, button 3 is moved to the right in the drawing. This takes place with entrainment of the second slider 20, since this is carried along via the driver 23 and the bolt 24. This also leads to a displacement of the first slider 4 to the right.
- the storage spring 6 is tensioned.
- the pin 13 is acted upon by force downward in the drawing via the tip 12 and the ramp 10 and the accumulator spring 6 is tensioned to the maximum until the pin 13 dips into the bore 15 and fixes the clamping device 1.
- the sliders 4, 20 now take the position accordingly Fig. 3 on.
- the trigger tail 9 is connected to a drive rod of the lock via the deflecting member 30 and the abutment 7.
- the button 3 is decoupled from the slider 20 via the ramps 26, 27; so that a further displacement of the button 3 does not lead to a change in the position of the sliders 4, 20.
- the second coupling independently decouples the rigid scissor kinematics and the lock.

In order to achieve a simple embodiment, it is provided that the clutch is two-stage and a first clutch fixes the energy storage device in the charged state.
Description
Die
Aus der
Bei dieser und ähnlichen Ausgestaltungen wird der Kraftspeicher in Form einer Feder beim Öffnen der Tür über den Drücker oder den Schlüssel und Zylinder neu aufgeladen. Dies erfordert eine gewisse Kraft beim Benutzer und eine entsprechende Auslegung des Antriebsmechanismus, der den Kraftspeicher laden muss. Es besteht daher der Wunsch nach einem einfachen Aufladen der gattungsgemäßen Vorrichtung, ohne große Bedienkräfte.In this and similar configurations, the energy storage device in the form of a spring is recharged when the door is opened using the handle or the key and cylinder. This requires a certain amount of force on the part of the user and a corresponding design of the drive mechanism that has to charge the energy storage device. There is therefore a desire for a simple charging of the generic device without great operating forces.
Zur Lösung sieht die Erfindung die Merkmale des Anspruchs 1 vor. Die Realisierung der Merkmale führt dazu, dass der Kraftspeicher beim Schließen des Flügels geladen wird. Die Betätigung erlaubt es daher die gesamte Flügelbreite als Hebelarm zu verwenden. Das Kraftspeicherelement kann daher ausreichend stark dimensioniert werden und die Riegelelemente werden mit größerer Kraft in die Riegeleingriffselemente bewegt. Da die erforderliche Aufladung des Kraftspeichers ohne Betätigung des Schlosses erfolgt, kann das Schloss den geringeren Betätigungskräften in Material und Konzeption ausgelegt werden.The invention provides the features of claim 1 as a solution. The implementation of the features means that the energy storage device is charged when the sash is closed. The actuation therefore allows the entire leaf width to be used as a lever arm. The energy storage element can therefore be dimensioned sufficiently strong and the locking elements are moved into the locking engagement elements with greater force. Since the energy storage device is charged without operating the lock, the lock can be designed for the lower operating forces in terms of material and design.
Eine Weiterbildung sieht vor, dass der Taster mit einem Mitnehmer eine zweite Kupplung bilden, welche bei vollständig gespannter Speicherfeder die Scherenkinematik und den Kraftspeicher voneinander trennt. Damit wird ein möglicher Zwang durch die Scherenkinematik vermieden.A further development provides that the button with a driver form a second clutch which, when the accumulator spring is fully tensioned, separates the scissor kinematics and the energy storage mechanism from one another. This avoids possible constraints from the scissor kinematics.
Die Ausgestaltung der Fixierung kann dadurch erfolgen, dass in einem Gehäuse ein relativ zu dem Kraftspeicher verschiebbarer erster Gleiter vorgesehen ist, der mit einem Stift mit einer Rampe an einer Keilfläche eines Spannkopfes des Kraftspeichers angreift, wobei der Sperrstift bei vollständig gespanntem Kraftspeicher in eine Rastausnehmung des Gehäuses eingreift und den Gleiter relativ zum Gehäuse festlegt. Diese Ausgestaltung setzt nur einfache Bauteile voraus und die Speicherfeder wird im gespannten Zustand gehalten.The fixation can be designed in that a housing is provided with a first slider which is displaceable relative to the energy storage device and which engages with a pin with a ramp on a wedge surface of a clamping head of the energy storage device, the locking pin in a latching recess of the energy storage device when the energy storage device is fully tensioned Housing engages and sets the slider relative to the housing. This configuration only requires simple components and the accumulator spring is held in the tensioned state.
Eine kraftschlüssige Kopplung kann dadurch erreicht werden, dass die Kupplung einen zweiten Gleiter aufweist, der in dem Gehäuse geführt ist und mit dem ersten Gleiter entgegen der Kraft des Kraftspeichers in Druckverbindung steht und einen Mitnehmer aufweist, der mit einer Keilfläche dem Taster zugeordnet ist, wobei der Taster an der Keilfläche des Mitnehmers angreift und die Keilfläche eine Rampe bildet, welche den Mitnehmer aus dem Verschiebebereich des Tasters bewegt, und an der Rampe eine Feder wirksam angreift, welche die Rampe in den Verschiebebereich kraftbeaufschlagt.A non-positive coupling can be achieved in that the coupling has a second slider, which is guided in the housing and is in pressure connection with the first slider against the force of the energy accumulator and has a driver which is assigned to the button with a wedge surface, with the button engages the wedge surface of the driver and the wedge surface forms a ramp which moves the driver out of the displacement range of the button, and a spring effectively engages the ramp, which forces the ramp into the displacement range.
Um eine einfache Ausgestaltung und Montage zu erreichen, ist vorgesehen, dass die Speicherfeder und die Kupplungen in einem im Wesentlichen rohrförmigen Gehäuse aufgenommen ist.In order to achieve a simple configuration and assembly, it is provided that the accumulator spring and the couplings are accommodated in an essentially tubular housing.

Ein zweiter Gleiter 20 ist ebenfalls im Gehäuse 2 verschiebbar gelagert und stößt mit dem Deckel 21 an den Gleiter 4 an. Dadurch stehen die beiden Gleiter 4, 20 ausschließlich in Druckrichtung in Verbindung. Der zweite Gleiter 20 ist topfförmig und der Deckel verschließt den Hohlkörper an einem Ende. Der Taster 3 ragt mit seinem keilförmigen Ende 22 in den Gleiter 20 hinein. In dem Gleiter 20 ist ein Mitnehmer 23 vorgesehen, der in dem Gleiter 20 mit einem Bolzen 24 an der Wand 25 befestigt ist. Der Mitnehmer 23 und der Taster 3 liegen mit Rampen 26, 27 aneinander.
