Definitions

• the invention relates to a door lock with at least one lock bolt and / or a lock latch and at least one control element which controls the lock bolt and / or the lock latch mechanically or electrically and is spring-loaded in a failure position and which has a control shaft and a control head, the wedge-shaped and with his wedge tip with the control wedge engages with the control wedge an opening in the faceplate of the lock when the door is closed.
• buttons or auxiliary bolts control downstream mechanical or electrical components in the interior of the lock housing. They have in common that when the door is closed they rest with their pushbuttons or bolt heads on the striking plate, that is to say do not penetrate into a door frame or the like through an opening of the striking plate; In contrast to door latches, they therefore have a purely control function, but no locking function.
• DE 39 38 655 A1 describes a lock of the generic type, which is designed as a self-locking panic lock with a slide which can be moved in the longitudinal direction of the lock and controls the locking of the bolt.
• the locking or unlocking of the bolt connection takes place by means of a spring-loaded auxiliary bolt, which projects in the closed position of the bolt with its bolt lock over the slip.
• the bolt head is chamfered on one side to ensure that the auxiliary bolt is automatically inserted into the lock housing when the door is closed.
• the bolt head and bolt shaft form a rigid unit.
• the aforementioned lock cannot be used for doors with either right or left hinges without additional fittings.
• the probe head and stylus shaft also form a rigid unit.
• DE 43 37 969 A discloses a self-locking security door lock with a spring-loaded, preloaded slide in the longitudinal direction of the lock, which controls the bolt lock.
• the bolt lock is locked or released by means of the push-button protrusions protruding, which can be used for doors with right or left hand.
• - Left stop chamfered on both sides and connected in one piece to the shaft of the button.
• the bevels of the probe heads are always 45 ° to the right of the longitudinal axis of the probe, so that there is a short length and therefore a short stroke with respect to the wedge-shaped probe head.
• the bevel of 45 ° is required to ensure a required chamfer for the automatic pushing back of the button head when the door is closed.
• the short stroke on the other hand, requires a precise fit with regard to the air gap between the faceplate and striking plate and the components to be controlled within the lock, which is perceived as disadvantageous.
• the button according to DE 36 31 118 A1 also has bevels on both sides, which in the closed position locks both a retaining bolt and the lock bolt of a security lock in their advanced position.
• the button head and button shaft are made in one piece, so that the lock has the same disadvantages as described above.
• an electromagnetic door opener interchangeable lock with a latch bolt which fits into the striking plate of a lock latch has also become known, the latch bolt having a latch bolt front part which can be pivoted on one side with respect to the latch bolt main part (latch shaft).
• the latch bolt front part can be locked or released from the latch bolt shaft by means of an electromagnetically operated lever mechanism.
• the solenoids When the solenoids are energized, the door can be opened by pressing the door leaf without the additional actuation of a handle or key.
• the device described above is not a control element, but a lockable trap serving to lock; The intended function of the latch bolt is only guaranteed in cooperation with an electromagnet.
• DE 38 12 313 A1 describes a so-called cross latch, which surrounds an opening in a striking plate and is provided in a mirror-symmetrical arrangement one above the other with two latch members pivotable relative to the drop shaft, each of which is supported on the inner surface on the faceplate with a chamfered surface.
• the arrangement is such that the door can be opened from both sides by pressing the door leaf without the additional actuation of a handle or key, if an electromagnet required for this purpose swivels a locking member blocking the cross latch into a passive position by means of current supply.
• This is not a control element in the sense of the invention, but rather a latch serving for locking purposes, the intended function of the latch also being guaranteed only in cooperation with an electromagnet.
• the object of the invention is to design the control element of a door lock described above in such a way that the advantage of a large working stroke is combined with a universal usability for right-left doors.
• the possibility is to be opened of being able to effect more complex control processes in cooperation with other components, such as further latches, bolts or further auxiliary latches, by mechanical or electrical transmission of control processes.
• control head can be pivoted to a limited extent in both directions of movement about an axis running in the longitudinal direction of the door lock relative to the central longitudinal axis of the control shaft in such a way that the control head in contact with the pivoting limitation has approximately one wedge surface parallel and the other wedge surface at an angle of approximately 45 ° to the central longitudinal axis of the control head are designed as run-on bevels, the primary controlling function, that is, the retraction of the control element in the lock, regardless of the use of right-hand or left-hand doors, whereby the same (long) control stroke as with known auxiliary latches with a bevel on one side is guaranteed.
• the function is delayed Guaranteed locking of the lock bolt in a previously known manner.
• the pivoting of the control head or the control wedges forming part of the control head causes delayed extension of the control element compared to conventional buttons, which can be used for time-delayed control processes during the opening process, this applies especially in the interaction of the actual lock latch, the lock bolt or other auxiliary latch provided in the conventional manner with a one-sided run-up slope.
• a reliable swivel limitation is ensured if corresponding swivel limitation surfaces are arranged on the control shaft on the one hand and on the control head on the other hand, the control shaft having a swivel limitation surface that is orthogonal to the central longitudinal axis of the control shaft and the control head has two swivel limitation surfaces that run at an angle of approximately 135 °. With a wedge angle of the control wedge of approximately 60 °, this results in a pivoting of approximately 30 ° in both directions of rotation.
• the latching device itself can be formed by a spring element which snaps into a notch in the control head, the spring element automatically disengaging from the notch when a door is closed or opened.
• the compression spring which is required anyway for closing the control element, can be used as the spring element which effects the latching process.
• control element can be assigned one or more auxiliary traps, the drop shaft of which is integrally connected to the catch head having a one-sided bevel, so that, for example, when the door is opened when using the control element on the one hand and a known auxiliary trap on the other hand result in two different switching points, the switching point of the control element according to the invention lagging the switching point of the known auxiliary trap.
• the known auxiliary latch can, for example, advance over the main latch and the control latch according to the invention can be synchronous, for example, when closing, and lagging when opening in the manner described above.
• control element according to the invention can be used with any locks, that is to say both with locks for right and left-hand doors and with locks which are only intended for a right-hand or left-hinged connection, in particular when successively connected in context Switching points for triggering a mechanical or electrical pulse are desired.

• the essential components of the door lock 1 shown in FIGS. 1 to 3 correspond to the door lock according to the German patent application P 198 27 516, the disclosure content of which is incorporated by reference.
• the door lock has a lock bolt 2, a lock latch 3 and a control element 4, which cooperate with a slide 20.
• the slide 20 which is pushed downward spring-loaded in the image plane, is held in the position shown by its projection 21 which interacts with the control element 4.
• Figure 2 shows an intermediate phase in which the door lock 1 is already in contact with a striking plate 8, but the bolt 2 and the latch 3 have not yet been able to enter the striking plate 8.
• the already closed control element 4 has already released the slide 20, but the slide 20 is prevented from moving downward by the lock latch 3, since the locking of the slide 20 by the lock latch 3 takes place due to the advance of the lock latch 3 before the time at which Control 4 releases the slider 20.
• the lock latch 3 has released the slide 20, so that the lock bolt 3 and the lock latch 4 are pre-locked.
• FIGS. 4a and 4b show the pivoting of the control element 4, which is mounted in a lock housing 19, into the striking plate 8. From FIG. 4b it can be seen that the control element 4 during the pivoting-in process. access in a known manner in the lock housing 19.
• Figure 4c illustrates that when swinging back, that is, when opening the door in the direction of arrow 24, an obstacle shown here, for example, as hole 23 has no adverse effect on the opening process, because a wedge tip 7 of a control wedge 9 swing out and assume the position shown in Figure 5 can.
