Description

The invention relates to an all-glass door lock with a spring-loaded case and a rotatably mounted nut that a polygonal hole for receiving a push rod Has door handle and with the trap by means of a sliding trap backdrop is coupled, and that of a Spring is biased into an initial rotational position, which the Initial rotary position of the door handle corresponds, with the Nut is a lever arm which is formed in the Starting rotary position of the nut lies against a stop.

Door locks in the form of box locks differ among other things, that the door locks on the one hand only one Have traps by a doorknob or a knob and if necessary additionally from a locking cylinder is operated, or on the other hand a latch and a bolt have, the case of a pusher and / or a Lock cylinder and the bolt only from the lock cylinder is operated. The nut through which a square pin of the Door handle or knob extends, has at least one Lever arm on, by means of a lever mechanism with the trap is coupled into the door lock housing for its retraction.

A door lock is known from DE 696 16 011 T2 rotatable nut has two lever arms, one of the Lever arms on the sliding, spring-loaded latch attacks and this between an extended position in which the trap is extended, and an insertion position in which the trap retracted into the door lock, can move. The one first lever arm essentially diametrically to the nut oppositely arranged second lever arm is with a Spring coupled that the nut in the starting position retrieves when there is no force on this by the pusher acts more on the outside. There is a in the housing of the door lock cone-shaped stop provided on which the lever in the Starting position of the nut is in contact.

From the starting rotary position of the nut and the one in it Trained square for the pin of the door handle will also the position of the handle of the door handle in its starting rotary position determined in which the door handle is not operated.

Generally, the handle of the doorknob extends in their starting rotary position horizontally or depending on the design the door handle and its relative position to Square pin / handle bar the door handle is turned up to 2 ° 30 '. By Manufacturing tolerances and signs of wear in particular With heavy lever handles, however, deviations in the Target position of the door handle can be caused.

The invention provides a type specified in the introduction trained all-glass door lock created in the Deviations from the desired target position of the door handle can be largely avoided.

According to the invention, the stop on which the nut of the all-glass door lock mentioned in the Starting rotary position is present, by adjusting the Starting rotary position of the nut and thus the door handle adjustable.

By adjusting the starting rotary position of the nut can be made by the stop from which this starting rotational position is determined, can be adjusted, it is simple possible, the starting rotary position of the nut and thus the Door handle adapted to the desired target position of the handle arm the door handle depending on its design and according to specifications by the architect, who often has a 0 ° position of the handle arm preferred to adjust or adjust without that Modify the handle part and / or the lock or to have to rework. In addition, one is in the design of the Lever handle part independent of the lock construction, so that Door lock and handle parts largely combined as desired can be.

All known door locks of the present type have one Stop on which the nut with a projection that in the most cases as a protruding lever arm, one Nut arm, is formed in its initial rotational position attacks. The lever arm according to the invention can be used as a projection, as a nose or e.g. than radially at a distance from the axis of rotation of the Radial shoulder should be trained and on the Stop. Depending on which direction the stop is is adjusted, the nut is rotated about its axis of rotation, which changes the starting rotary position of the nut. There the nut into the starting rotary position by means of a spring is biased, it is always close to the stop.

According to a preferred embodiment of the invention, the a spring engaging the lever arm on the door lock housing supported compression spring that permanently presses the lever against the Stop presses. The door handle is thus actuated always against the force of this compression spring, of which the nut and so that the door handle returns to its original position is retrieved when there is no more power on the doorknob acts.

As an alternative to this compression spring, which is directly on the lever arm attacks, but can also use a different spring as a return means be arranged for the nut that is not on the aforementioned Lever arm attacks. For example, spaced from the lever arm a second lever is formed on the outer circumference of the nut which the spring engages, or an eyelet can be formed in which a tension spring is hooked in, the other end of one e.g. Hook attached to the door lock housing is so that the nut is not pressed against the stop but is pulled against it. If necessary, it is also possible to couple a separate latch spring to the nut in this way, that not only the trap spring but also the trap spring Nut pressed or pulled into its respective starting position become.

According to one embodiment of the invention, the stop of a grub screw formed in a threaded portion of the All-glass door lock housing is supported. By entering or Unscrew the grub screw with its free end on attacks the lever arm, this can be in its position in front or be moved back, that means the nut is turned around accordingly their axis of rotation rotated. As a result, the Handle pin and thus the handle arm of the door handle also be rotated / adjusted accordingly, so that these in the desired initial target position can be brought.

However, the stop can also e.g. as rotatably mounted Eccentric disc be formed with its eccentric edge attacks the lever arm. By turning this eccentric disc the starting rotary position of the nut can also be adjusted.

According to a development of the embodiment in which the Stop is formed by a grub screw, that is free end of the grub screw on the attack side, conical trained, the grub screw preferably with her Tapered surface engages the lever arm. The is preferred Cone formed at an angle of 90 °. Because the grub screw attacks with its conical surface on the lever arm, the Lever arm and thus the nut in a particularly advantageous manner very fine steps can be adjusted.

According to a further embodiment, the is adjustable Stop adjustable at an end stop, from which the maximum starting rotary position is determined. The end stop can, for example, one accommodated in the door lock housing and integrally formed with this rib or an approach his. By means of this end stop, a maximum Angle of attack in which the door handle with its free end protrudes furthest upwards, predefined or preset and thus limits the pivoting range of the nut in this direction.

According to a further embodiment of the invention, the Lever arm together with the latch link as an actuating arm, what means on the nut instead of two separate ones Lever arms only one lever arm is formed.

According to a preferred embodiment of the invention Stop adjustable from outside the all-glass door lock. This means that the starting rotational position of the nut e.g. to Removal of the outer panel can be adjusted without the lock case must be opened. In particular it is this makes it possible to stop at the door leaf mounted lock case and in the polygonal hole of the nut inserted push rod to adjust so that by the Setting the stop directly the desired location of the Door handle regardless of the month tolerances of the door lock can be adjusted or adjusted. At this The adjustable stop has an embodiment Actuating part with key surfaces for a tool, the actuating part through an opening in the Lock case housing protrudes to the outside or through such an opening for a tool like one Allen key or a screwdriver is accessible. This can be realized particularly easily if the adjustable stop is rotatably actuated, that is e.g. from a rotatable eccentric disc or from one Screw is formed or by means of an eccentric disc or Screw is adjustable.

The invention is explained in more detail with reference to the exemplary embodiments shown at least schematically in the drawing.

Fig. 1 shows an open box-shaped all-glass door lock according to a first embodiment;

Fig. 2 shows an open box-shaped all-glass door lock according to a second embodiment.

Fig. 1 shows an open box-shaped all-glass door lock 1 in plan view, which can be attached to the edge region of an all-glass door leaf on one side surface. The all-glass door lock 1 has an elongated, box-shaped housing body 2 with a lock base, a lock cover (not shown) and with side walls protruding from the lock base, all components of the door lock being accommodated in the housing body 2. In the side wall 3 of the housing body 2, which is assigned to the free wing edge of the all-glass wing, an opening 4 is formed through which the movable latch 5 extends in its extended position out of the door lock 1, the side wall 3 opposite the side wall in the rear area of the housing body 2 is arched in the embodiment.

The trap 5 is by means of a biasing mechanism 6, the one Compression spring (latch spring) 7 contains, in their extended position preloaded and can on the one hand by means of a locking cylinder (not shown) in the door lock in a corresponding recess 8 is received in their Retracted position, in which case 5 is within the Door lock can be retracted by the driver of the lock cylinder on the biasing mechanism of the trap attacks and this against their bias in the Moves or pulls in the door lock housing 2. On the other hand, the latch 5 can be actuated by the pawl 11 in their retracted position are spent.

The jack 11, depending on the circumstances on at least one Lock or door side is arranged with a Pusher pin 12 provided by the Polygonal recess of the nut 13, which in the door lock 1 is rotatably received, extends. The nut 13 used in this Embodiment in the rear or rear area of the Housing body 2 is arranged, has this Embodiment a driving arm 14, the free end cooperates with a movable latch 9. By Actuate, that is, move the latch link 9 within of the all-glass door lock housing, the case 5, which with the Trap link 9 is connected from its extended position in the Retracted position shifted.

The pawl 11 is down in this embodiment pressed, the pusher pin 12 rotates at the same time Nut 13 and thus also the driving arm 14 in a clockwise direction. The driving arm 14 engages on the link lever 15 Trap backdrop 9 and pulls the link lever 15 at the illustrated embodiment to the right, whereby after Transfer of the movement via the trap scenery 9 to the trap 5, this is withdrawn into the door lock 1. The power that acts on the latch 5 on the latch 5 must at least so be great that the force of the latch spring 7 of the latch 5 biasing biasing mechanism 6 is overcome. As soon as the pawl 11 and thus on the link lever 15 Trap backdrop 9 no longer acts from the Fall spring 7, the trap backdrop 6 in its initial position and the latch 5 pulled back into its extended position or pressed.

In the embodiment shown in FIG. 1 , the nut 13 has a lever arm 16 which is formed on the nut 13 approximately opposite the driving arm 14. The nut 13, which is rotatably mounted in the door lock 1, lies with this lever arm 16 against a stop 17, by means of which the starting rotational position of the nut 13 is determined. From this starting rotational position of the nut 13 and the pusher pin 12 received therein for the pawl 11, the preferably horizontal position of the handle of the door handle 11 in its initial rotational position is determined, in which the pawl 11 is not actuated. Depending on the nut starting rotary position, which is determined by the position of the stop 17, the position of the handle is determined, which is horizontal in the broken line (0 ° position).

On the side of the lever arm opposite the stop 17 17 engages a slider 18 on this, which by a Compression spring (nut spring) 19 is encompassed and within the Door lock housing 2 is slidably received. The Nut spring 19 is at one end on the head of the slide 18 and with its other end to one in the door lock housing 2 trained projection supported and pushes the slide 18th permanently against the lever arm 16 and thus against the Stop 17. After pressing and releasing the pawl 11 is the same in this embodiment on the one hand the sliding trap backdrop 9 in its starting position returned by the link lever 15 the driving arm 14th actuated and thereby the nut 13 rotates. At the same time, the Slider 18 due to the pressure force of the nut spring 19 Lever arm 16 and thus the nut 13 until this in their Starting rotational position reaches, that is, until the lever arm 16 to the Stop 17 is present.

As can be seen in FIG. 1 , the stop 17 in this embodiment is a grub screw which is screwably supported in the door lock housing 2 in a threaded hole opening on the rear or rear side wall of the lock case 2 and extends essentially radially to the nut 13 , The free end of the grub screw forming the stop 17 is conical, the grub screw resting with its conical surface against the lever arm 16 and forming the stop / contact surface. The other free end of the grub screw has an internal polygon in which an Allen key 21 can be used. The position of the stop 17 can be adjusted by screwing the grub screw in or out of the door lock housing 2. Starting from the position of the grub screw shown in the figure, when the screw is screwed in further, it moves it to the left and thus rotates the push pin 12 inserted in the square recess of the nut 13 in a clockwise direction, with the result that the handle of the doorknob moves downward inclined position is moved (position 11.1). When unscrewing the grub screw, the lever arm 16, which is pressed by the nut spring 19 against the free end of the grub screw, is moved to the right, so that the handle of the pawl 11 is raised after the "0 ° position" has been exceeded (item 11.2 ).

By adjusting the stop 17 can thus easily Way the handle arm of the pawl 11 in each desired / required initial target position can be set.

There is also an end stop within the door lock housing 2 22, of which the maximum initial rotational position of the Nut 13 is determined and on which the lever arm 16 rests when for example, the adjustable stop 17 too far is unscrewed.

In the embodiment shown, this is the stop 17 forming grub screw in the rear or rear Side wall of the housing box 2 is supported by screws. Alternatively, this can also be done at an end stop, that of e.g. an intermediate wall section, a rib in the Door lock housing 2 or an extension 22 can be formed be screwed in or unscrewed.

According to another embodiment, the lever arm that is on the adjustable stop is also from the Driver arm 14 formed with the lever mechanism 9th interacts as an actuating arm. In this case for example at the bearing 20 an eccentric be rotatably included, with its eccentric edge on the Driver arm 14 abuts and forms the adjustable stop. By turning this eccentric disc, the Starting rotational position of the driver arm 14 and thus the nut 13 to be changed. The eccentric disc can Have rotary actuator that through a hole in the lid of the Lock case 2 protrudes to the outside of the cover and flush with this, or through such a hole through for a tool like a screwdriver from is accessible outside the lock case.

FIG. 2 shows an open case lock according to a further embodiment of a door lock 1, which differs from the embodiment according to FIG. 1 essentially in that no lock cylinder is accommodated in the door lock 1 and consequently the latch 5 only by means of the door handle 11 can be actuated, and that the lever arm 16, which rests on the stop 17, serves at the same time as an actuating means for the latch link 9. The lever arm 16 borders with its side opposite the stop 17 on a link section 24 of the latch link 9. When the door handle 11 is actuated, the nut 13 is rotated clockwise, whereby the lever arm 16 presses against the link portion 24 of the latch link 9, which overcomes the pretensioning force of the latch spring 6 within the door lock housing 2 and thus moves the latch 5 into it Door lock housing 2 is withdrawn. As soon as no external force acts on the pawl 11, on the one hand the latch 5 is pushed out of the door lock housing 2 again due to the force of the latch spring 6 and on the other hand the nut 13 is rotated back into its initial rotational position, this time counterclockwise, due to a further spring arrangement. For this purpose, a second lever 16.1 is formed on the outer circumference of the nut 13, which is spaced from the lever arm 16 and on which a slide 18 preloaded by a compression spring 19 engages. The compression spring 19, which is supported at one end on the door lock housing 2, presses the slider 18 permanently against the second lever 16.1 and thereby the nut 13 into its starting rotational position, in which the lever arm 16 bears against the stop 17.

The adjustable stop 17 is also formed in this embodiment as a grub screw, which rests with its conical lateral surface on the left side in FIG. 2 of the lever arm 16 and thus limits the rotary movement of the nut 13 in this one direction. In addition to the nut 13, an extension 22 is formed in the door lock housing 2, on which the grub screw is supported so that it can be screwed in and out. The extension 22 can either be formed in one piece with the door lock housing 2 (for example as a cast part) or can be fixed therein by means of fastening means. By screwing in or unscrewing the grub screw, the lever arm 16 can be moved, the nut 13 rotated and thus the starting rotational position of the nut 13 can be adjusted.
In this embodiment, the projection 22 in the door lock housing 2 simultaneously forms the end stop for the lever arm 16, from which the position of the pawl 11 in which the pawl 11 protrudes the most is determined. However, the lever arm 16 is only in contact with the upper section of the extension 22, that is to say against the end stop, when the free end of the grub screw forming the stop is screwed into the extension 22.

In the lower longitudinal side wall of the door lock housing 2 shown in FIG. 2 , an opening 23 is formed, through which a tool such as a wrench 21 can be inserted into the door lock and the adjusting screw can be adjusted.

A particular advantage of the described embodiments is that the adjustable stop from outside the Door lock is accessible and therefore adjustable, so that The housing of the door lock 1 itself does not have to be opened, if the target position of the door handle is set, or if the the target position must be set again.
