Description

Lock.

The invention relates to a lock of self-locking according to the preamble of claim 1.

It is known from document DE 196 26 752 A1, with respect to which claim 1 is limited, a Self-locking insert lock, with a crossed latch spring loaded, a slide-controlled bolt, a slide that can be activated in the longitudinal direction of the lock by activating a key, and with one piece control that ties the slide when the bolt is displaced  back and the cross latch is moved forward. In in this case, the slide is locked, when the bolt is shifted back and the cross latch is free, in a stop arranged in the area of a closing cylinder contour.

In this case it is an inconvenience that the insert lock, under its construction measures, It is only suitable for doors with a long lock bag, such as metal doors. The lock cannot be used in the wooden door lock bag, since these doors they have shorter lock bags, but instead more deep. Also, when the door is open, through manual activation of the control piece, for example by means of children playing, you can activate the expulsion of the bolt, with what that the door can no longer be closed. This is especially unfavorable when the door is provided with a drive door or is controlled from a central.

Document DE 197 01 761 C1 shows a self-locking lock with a bolt, a lock latch, an auxiliary latch and a sliding plate, in which the bolt and the lock latch are ejected under spring impulse and are they block when the door is closed and in the ejected position, and in which the bolt is tied when the door is open and in the fully retracted position by means of the auxiliary latch on the sliding plate. Through the introduction of pressure of the auxiliary latch during the closing of the door the tie the bolt and the bolt is ejected. In this case, the bolt  advances when the door opens in front of the lock latch, so that the lock latch is provided with a latch piece, with which the lock latch goes behind of the auxiliary latch, so that the sliding plate and the bolt are tied by the lock latch to the auxiliary latch ties the slide plate and with it the bolt. The latch piece is received, during closing, in the lock latch and the lock latch is locked in its ejected position through the slide plate.

It is an inconvenience that the lock under its construction size cannot be used universally in Different lock bags. Since the closed position of the door can only be detected unilaterally through the latch of the lock, an expulsion of the bolt against the closing plate, and the bolt does not close with door security. Additional widening of the latch arranged in the latch through the latch piece is possibly susceptible and could get stuck.

The invention has the task of configuring a lock, which can be inserted in an embodiment in the lock bags for metal doors and wooden doors, is insured against unforeseen expulsion of the bolt and that guarantees a secure engagement of the bolt in the closing plate.

The task is solved through the characteristics of claim 1.

The dependent claims form advantageous configuration possibilities of the invention.

Self-locking locks are used with frequency in exterior doors to ensure that a building It is closed intrusion proof. Such locks are configured also as self-locking panic locks, which are used in escape routes and rescue routes. Through the panic function, by pressing down on the door handle, it retract the latch and the bolt in the lock, so that You can immediately open the previously closed door.

Locks are usually manufactured in different embodiments, since, for example, the metal doors have, as far as the measures, a bag of lock for housing the lock other than metal doors The wooden doors have bags of deep lock with a lower height, instead the metal doors only allow a mounting depth reduced, but a higher construction height. The lock of according to the invention is configured in its measurements of such shape that fits the same way in the lock bags of metal doors and wooden doors, since its special construction is made to the smallest size respective of the lock bags. This is especially advantageous, since only one lock is necessary for Different types of doors.

A lock collaborates, as is known, with a closing plate arranged in the door frame, which presents one or more recesses, in which a latch can fit and a lock Known cross latches are constituted by two latch elements arranged immediately adjacent, that can be articulated outside the lock skirt and they can fit in the recess of the closing plate.

Instead, the divided arrangement of a crossed latch with an upper latch element above and with a lower latch element below the bolt enables a centering of the lock in front of the closing plate and, therefore, a safe ejection and engagement of the bolt in the recess of the closing plate.

The latch elements are articulated in this case outside the skirt inside the recess in the closing plate, so that the skirt elements are support, respectively, on one of the opposite inner sides of The recess. Through the bolt arrangement between latch elements and the smallest width of the latch, with with respect to the outer distance of the latch elements articulated outward, this can be ejected completely free in the closing plate. However, an inclined position possibly existing of the closing plate in front of the lock, for example due to contraction of the door, you can focus on virtue of the distance between the upper latch element and the bottom latch element.

In the self-locking locks is especially important that no expulsion can be made unforeseen of the bolt when the door is open. To that end, in Locks of this type are provided with an auxiliary latch which, when the door is closed, it is activated through the sheet of Close and release the ejection of the latch. However, the latch auxiliary can also be activated, for example, by children playing, thereby activating the ejection of the latch and, consequently, The door can no longer be closed.

Therefore, the lock according to the invention presents an exit insurance, which only activates an ejection of the bolt when the auxiliary latch has been activated and at the same time the latch elements and then the latch elements have again reached the articulated position out of the skirt. This cycle corresponds to a closing process of the door, in which the auxiliary latch and the elements of latch are articulated through collaboration with the sheet metal closing. After the door is completely closed, the latch auxiliary remains activated and the latch elements fit into the recess of the closing plate and reach its articulated state out. Only in this way is the expulsion of the latch.

The bolt loaded by means of a spring is guided in a guide arranged in a slide. Only through of the release of the sliding movement of the slide, the bolt can change its position and can be guided by from the dock beyond the cold skirt of the box lock.

For the liberation of the movement of sliding of the slide is necessary, on the one hand, the activation of the auxiliary latch and, in addition, the activation of the elements of the skirt. The slide also presents another lock by means of an articulation lever, which only is released when the skirt elements are again fully articulated out. Only this sequence releases the slide and can eject the spring loaded bolt, being guaranteed that the door is closed and the bolt is centered through the latch elements in the recess in the closing plate and in this way can be ejected freely. The Door locks securely.

The lock can be configured as purely mechanical self-locking lock and could be equipped with a panic function, so that the lock can be unlocked from the side at any time through the activation of a button. From the other side it is only possible an opening of the lock usually through a cylinder of closure, since instead of a button only one door knob, to prevent unauthorized access.

However, the lock may be equipped also with a doorknob, which can be activated, by example, electromagnetically. In this way it is possible undock the latch on one side of the lock of the mechanism opening, so that access to a safe area can be controlled. This can be done through an access control, either to through a concierge or through a control system electronic access, such as chip card, code entry or fingerprint. In case of authorized access, the two are coupled halves of the doorknob with each other - activated by means of electromagnet. And the lock can also be activated through a exterior latch The status of the lock can be detected in this case through switching elements and can lead to A control of the alarm installation.

The lock can also be equipped as motor lock In this case, an engine can activate through of a toothed belt an activation element, so that they are conceivable several activation positions, which perform Different functions of the lock. The state of the lock and of the activation element can be detected in this case through of switch elements.

For example, a daytime position and a night position or a permanent open position, so that the activation element is carried by means of the motor to the respective necessary position. The position for the control of Motor can be detected through the switching elements. To enable quick access to a very frequented door, for example, throughout the day, you can do without expelling the bolt. The latch elements can perform a lock and assume a function of opening the door. If the elements of latch are locked, the door cannot be opened, but it is accessible immediately after release, either through of an electronic access control system or through a concierge, since the latch elements can be articulated inward immediately after release. It removed an insertion of the bolt with motor, which always requires a certain time, so you can access faster than in the usual engine locks.

However, for night operation or on weekends it may be necessary for the bolt to be ejected and the door is secured against breakthrough. Such Finally, the activation element can be moved to another position, with what the bolt is ejected. For authorized access, the activation element causes the bolt to be inserted again in the lock case. After the next closing of the door, an expulsion of the bolt for a secure door lock.

An example is explained in detail below. of realization in the drawing with the help of the figures. In this case:

Figure 1 shows a lock with a latch Split crossed and safe fall, open in side view.

Figure 2 shows the lock according to figure 1, in sight on the skirt.

Figure 3 shows the lock according to figure 1, configured as motor lock.

Figure 4 shows the lock according to figure 3, in the partially disassembled state, with the representation of bolt lock when latch elements are articulated out.

Figure 5 shows the lock according to figure 4, but with latch elements articulated inwards.

The figures show a lock 1 of self-locking with a skirt 2 for mounting lock 1 on a door lock bag not shown here in detail, with a lock box 3, which is received in the bag of door lock. In this case, the lock box 3 is configured in its measurements in such a way that the lock 1 fits also in the metal door lock bags and wooden doors. This is especially advantageous, since for different types of doors only one lock 1 is necessary. Wooden doors feature deep lock bags with a smaller height. Instead, metal doors only allow a reduced assembly profanity, but a height of major construction Lock 1 is made through its special construction to the less respective extent of the bags lock. The skirt 2 of the lock 1 shown in the view in upper floor in figure 2 is replaceable, making it possible easily adapting to different embodiments of the door.

Lock 1 collaborates, as is known, with a closing plate arranged in the fence, which has one or several recesses 28, in which a latch and a bolt can fit 6. The recess 28 represents schematically as lines of strokes, of the closure plate not shown in detail illustrates the Optimal bolt centering 6. Known cross latches they consist of two latch elements 4, 5 arranged immediately adjacent, which can be articulated inwards in the plane of the skirt 2, and in the articulated state out they engage in the recess 28 of the closing plate arranged in the door frame.

The split arrangement of the cross latch, with an upper latch element 4 above and with an element bottom of latch 5 below bolt 6, allows a centering of lock 1 in front of the closing plate and, therefore both a safe ejection and engagement of bolt 6 in the recess 28 of the closing plate. The latch elements 4, 5  are articulated in this case out of the skirt 2 until the inside of the recess 28 in the closing plate, so that latch elements 4, 5 rest, respectively, on one of the opposite inner sides of the recess 28. Through the arrangement of bolt 6 between latch elements 4, 5 and of the smallest width of bolt 6, with respect to distance exterior of latch elements 4, 5 articulated outward, This bolt can be completely ejected freely in the sheet of closing. A possibly present inclined position of the sheet closure in front of lock 1, for example due to contraction of the door, you can focus despite everything under the distance between the upper latch element 4 and the element bottom latch 5.

In self-locking locks 1 it is important that no unexpected expulsion can be made from bolt 6 When the door is open. To this end, in locks 1 of this type known is provided an auxiliary latch 11, which moves during the closing of the door through the closing plate and releases the expulsion of the bolt. However, the latch auxiliary 11 could also be activated, for example, by children playing, which activates the expulsion of the bolt and from this way you can not close the door anymore.

The bolt 1 according to the invention presents a fall insurance, which only activates an expulsion of the bolt when the auxiliary latch 11 and at the same time latch elements 4, 5 have been activated and then the latch elements 4, 5 have reached the position again articulated out of the skirt 2. This cycle corresponds to the door closing process, so that the auxiliary latch 11 and the latch elements 4, 5 are articulated through the collaboration with the closing plate. After the total closure of the door, the auxiliary latch 11 remains activated, but the latch elements 4, 5 engage in the recess of the sheet metal close and reach their articulated state out. Only from this way the bolt expulsion is activated.

The bolt 6 loaded by the spring 15 is driven in the guide 8 arranged in the slide 7, as depicted in figures 1 and 3. Through the release of the sliding movement of the slide 7 the bolt 6 can modify its position and can be guided through the pier 15 more beyond the skirt 2 outside the lock box 3. For the sliding movement release of slide 7 is necessary, on the one hand, the activation of the auxiliary latch 11, in which the lock 12 arrives from the engagement with the retainer of the auxiliary latch 13 arranged on the slide 7. In addition, the bolt lock 9 arranged on the rocker 21 of the lower element of latch 5 is engaged with latch retainer 10. The bolt lock 9 only releases the slide 7 when the elements of latch 4, 5 are articulated out. The elements of latch 4, 5 are in operative connection with each other through the rockers 21 and can only be articulated in common, as deduced from figure 4. If the latch elements 4, 5 are outdated inward, then the recovery element 22, which is in operative connection with latch lock 23, is articulated such that the transmitter 24 is retained with a retaining bolt 26 on a retaining cam 27 of the element Recovery 22, In this way, the transmitter 24 and the slide 7 are locked, since the sliding pin 25 arranged on the transmitter 24 it fits into a recess in the slide 7. Yes the latch elements 4, 5 are fully articulated towards outside, latch lock 23 fits between the two rockers 21. The recovery element 22 can be articulated and the cam of retention 27 releases transmitter 24 and through the bolt of slide 25 releases slide 7. Spring loaded latch 6 You can move and eject the slide to the lake of guide 8.

Lock 1 can be configured as purely mechanical self-locking lock and can be equipped with a panic function, so that lock 1 can be unlock from the side at any time through the latch activation. From the other side it is only possible an opening of the lock usually through the cylinder of closure 16, since instead of a latch, only one doorknob.

However, it can also be configured with a split 14 latch nut, which can be activated electromagnetically In this way, it is possible to decouple the latch on one side of the lock from the opening mechanism,  with which you can control access to a safe area. This is can be done through an access control, either through from a concierge or through an electronic control system of Access, such as chip card, code entry or fingerprint. In case of authorized access, the two halves of the nut of latch 14 - activated through the electromagnet - are coupled each other and lock 1 can also be activated through the exterior latch The status of lock 1 can be detected in this case through switch elements 19 and can be conducted to a control or alarm installation.

Another configuration of the lock 1 is a lock that can be activated with a motor, which can be deduced from figures 3 to 5. In this case, a motor 17 can activate an activation element 20 through a toothed belt 18. Several activation positions are conceivable, which perform different functions of the lock 1. The state of the lock 1 and the activation element 20 can be detected in this case through the switching elements
tion 19.

It is conceivable a day and night position differently, so that the activation element 20 is brought to through motor 17 to the respective necessary position, so that the position is detected for motor control 17 through of switching elements 19. To enable access fast for a very frequented door, for example, along the day, it is possible to dispense with the bolt 6, since the latch elements 4, 5 can make a lock and assume a door opening function. If the latch elements 4, 5 they are locked, the door cannot be opened, but it is accessible immediately after release, either through a electronic access control system or through a concierge, since the latch elements 4, 5 can be articulated towards inside immediately after release. One is deleted motor bolt insert, which always requires a certain time, so you can access faster than in the usual engine locks.

However, during the night or at the end of week it is necessary that bolt 6 is ejected and the door be insured to breakthrough. This can be done at via a motor movement of the activation element 20 to another position, so that bolt 6 is ejected out of the guide 8 on the slide 6. For authorized access, it is inserted from new bolt 6 along guide 8 through activation  of the activation element 2 in the lock box 3. After Next door closure, is carried out again automatic an expulsion of the bolt for the safe blocking of the door.
