Description

The present invention relates to a lock with top-locking, in particular for installation in doors with a high door leaf.

For installation and operation of doors with a high door leaf, d. H. with heights from 3 m, or from doors that are to be additionally held in the frame, z. B. for security reasons, a complete concern of the top edge of the door leaf in the frame is often not guaranteed, z. B. because the door is warped. Therefore, for doors with a high door leaf usually in addition to the lock, a so-called top locking is provided, which extends the locking mechanism of the castle via a locking bar upwards. At the end of the locking bar is a kind of trap, which engages over a strike plate in the frame of the door. The locking bar itself is usually coupled to the trap of the lock and transmits the trapping movement to its upper end.

Lock-top locks are well known in the art. So describes DE 20 2009 008 430 U1 a lock with a one- or multi-part lock housing, a latch with latch tail, a follower nut and driven by the follower Nutschwenkhebel and arranged on the catch tail driver over which a projecting from the lock housing locking bar can be actuated. The locking bar is urged by means of a relief spring against the weight of the locking bar of the lock housing upwards.

In the locks known in the prior art, the control of the top lock and the attachment of the locking bar is placed on top of the existing lock case, which means that at the door additional preparations for installing a castle so changed, z. B. milling, must be made. Another common way to accommodate a top lock is the use of an enlarged lock case. A conversion or retrofitting of existing doors is thus associated with a considerable effort. Furthermore, with attached mechanism for the top locking the risk of contamination, z. B. by chips, and thus a malfunction greater than a variant with integrated mechanism in the lock case.

Based on the above-mentioned prior art, the present invention seeks to provide a universal lock that can be provided without major adjustments with a top-locking.

This object is achieved by a lock in which the recording and the control of the top locking are arranged inside the lock case.

1 represents a lock according to the invention 1 in outline schematically. The castle 1 is essentially a lock case 3 with an attached cuff 5 built up. In particular, the forend is 5 with two fastening elements of the housing 301 screwed.

The lock box 3 consists of a housing 301 a floor 303 at the back of the castle 1 and a blanket 305 on the front of the castle 1 , The floor 303 and / or the housing 301 have in the figures not shown recording and fasteners with which the ground 303 positively with the housing 301 connected is. By screwing with substantially the same receiving and fastening elements is the ceiling 305 on the housing 301 appropriate. The outside of the case 301 as well as the ground 303 and the ceiling 305 surrounded with the forend 5 all elements of the castle 1 and thus form a protection against external, especially mechanical, influences.

The housing 301 of the castle 1 has different functions. In addition to the pure holding and support functions for essentially all elements of the lock 1 The housing also performs stop and guide functions for some of the moving elements, such as the latch 7 , The Nut 9 and the latch 11 ,

As in 2 is shown schematically, there is the trap 7 essentially from a case head 701 a trap shaft 703 with a guide pin 707 for the top lock, a detent pin 709 and an attachment pin 705 , A trap pen 307 is in the case 301 stored and charged the trap 7 with a predetermined spring tension. The case head 701 is encapsulated with plastic on a part of its running surfaces for quiet operation, which is denoted by the reference K in FIG 2 will be shown. The case head 701 has at the rear part different receiving notches and is by means of a latching pin 709 at the fall shaft 703 attached. By using different receiving notches of the case head 701 can be set different mandrel sizes. The spine measurements are by inscription on the case head 701 to assign and adjust the respective notch during lock assembly.

Depending on whether the lock 1 as a right or left lock (ie DIN right, DIN left) should be used, the case head 701 rotated by 180 ° to fall shaft 703 to be assembled. The detent pin 709 is then either from the front or from the back in the fall shaft 703 pressed and thereby the case head 701 fixed.

The lock shown in the figures 1 has a so-called anti-panic function B ("APB function"). However, in other embodiments of the invention it may also have anti-panic functions D ("APD function") or E ("APE function"). The differences between the APB, APD, and APE functions are explained as follows.

Under APB function is understood in the context of the present invention, a door with switching function. From the inside, the door can be locked and unlocked by panic operation of the handle or with the key. Trap and bolt are retracted simultaneously via the door handle. Thereafter, the outer handle is idle. The panic function is only allowed when the key is removed. There is also a door handle on the outside of the door. The door can be locked and unlocked from the outside with the key. When the lock is locked, the outer handle is switched to idle. When the latch is closed, the outer handle remains idle. Only after a key switch is the door permanently accessible. Thus, the door can be opened via the door handle.

Under APD function is understood in the context of the present invention, a door with passage function. The door can be locked and unlocked from the inside by panic operation of the handle or with the key. Trap and bolt are retracted simultaneously via the door handle. The panic function is only allowed when the key is removed. On the outside of the door is a door handle. The door can be locked and unlocked from the outside with the key. When the latch is retracted, the door can be walked on permanently.

For the purposes of the present invention, the term "APE function" is understood to mean a door with a transformer replacement function. The door can be locked and unlocked from the inside by panic operation of the handle or with the key. Trap and bolt are retracted simultaneously via the door handle. The panic function is only allowed when the key is removed. On the outside of the door is a fixed knob. The outside can be locked and unlocked with the key. In the unlocked state, the case can be withdrawn with the key on the change.

In the illustrated embodiment with the APB feature adjusts the bottom side of the lock 1 the outside and the ceiling side of the castle 1 the inside or the panic side.

The neckstick 705 is in the present embodiment of the invention (APB function) only on the front of the trap shaft 703 assembled. (In contrast, the APD or APE function has two stylus pens 705a . 705b each on the front and back of the trap shaft 703 provided.) At the back of the trap shaft 703 there is a rounding on which the trap spring 307 tangential over the entire traverse path of the trap 7 can slide. At the same time the trap spring 307 by a protruding element on the rear fall shaft 703 guided.

The invention in the castle 1 provided top-locking comprises in particular a slide 13 , which in the housing 301 guided vertically and by means of a slider spring 309 is pushed upwards. In the upper part of the slider 13 Can have an opening in the housing 301 a latch bar 15 attached, in particular screwed, which serves for the top-locking, ie for locking in the upper door area, especially at high doors. At the bottom of the slider 13 there is a rounding on which the slider spring 309 tangential over the entire travel of the slider 13 can slide. The arrangement of the slider 13 is also in 2 shown schematically.

The slider 13 points as in 3 is shown, a substantially trapezoidal recess 1301 with a control cam, in which the guide pin 707 of the fall 703 engages and the movement of the locking bar 15 for the top-locking depending on the movement of the trap 7 controls.

As in 4 is shown schematically, comprises the bolt 11 winged doors a bolt head 1101 , a bolt tongue 1107 and a bolt shaft 1103 , The bolt 11 is at the rear, rounded end of the bolt shaft 1103 from one in the case 301 stored latch spring 313 subjected to a spring tension. In the part of the case 301 in which the rear end of the bolt shank 1103 is in a closed position, is a locking lever 311 with associated locking lever spring 315 intended. In this locking lever 311 can the latch 11 by means of a latch 311 at the end of the bolt shaft 1103 engage.

The bolt shaft 1103 has a receptacle for the bolt head in the front part 1101 on, with the bolt head 1101 depending on backset or closing direction ( DIN left, DIN right ) variable with the bolt shank 1103 can be connected. Inside the bolt shaft 1103 is the bolt tongue 1107 inserted, which can be inserted depending on backset or closing direction in different notches from the front or rear.

For double-leaf doors is also a latch release 1109 intended. In the bolt tongue 1107 and in a hole in the bolt head 1101 becomes this latch trigger 1109 guided. bolt tongue 1107 and latch release 1109 are after insertion in the bolt shank 1103 positively connected with each other and displaceable in the bolt closing direction.

The panic lever 17 is rotatable on one in the housing 301 provided pen 317 stored. In the upper part is a neck pin 1701 , depending on the design as a right or left lock on the front or back attached. This approach pen 1701 forms in the illustrated embodiment, the contact surface for the lower control arm 905a the cover-side nut half 9a , In the lower part of the panic lever 17 There is an internal contour into which the pin of the bolt tongue 1107 intervenes. The outer contour of the panic lever 17 is designed so that two on the bolt shank 1103 attached, not shown here driver the movement of the panic lever 17 when retracting the bolt 11 over the outer contour of the panic lever 17 Taxes.

For a lock according to the invention 1 with APB, APD or APE function includes the nut 9 each different components, which are combined depending on the desired function. A schematic overview of a lock according to the invention 1 with the components of the nut 9 is in 5 given. A two-parted nut 9 is shown schematically in detail in 7 shown. For the APB and APD functions, the nut includes 9 one half of the nut on each side 9a , a bottom nut half 9b and one between the nut halves 9a . 9b lying disc 9c , For the APE feature includes the nut 9 a cover-sided nut half 9a , a bottom nut half 9b and a (in 8th shown) nut turned part 9d ,

The cover-sided nut half 9a has a nut arm for the APB and APD functions 901 for the operation of the trap 7 , a lower control arm 905 with an internal opening with cam for actuating the tumbler 23 and a recording 911 for a 9 mm square.

For the APB function, the cover-side half of the nut is shown 9a also a recess 913a into which the nut coupling 903 can intervene. The bottom half of the nut 9b also has a recess 913b into which the nut coupling 903 can intervene. Grab the nut coupling 903 in both recesses 913a . 913b one, are the nut halves 9a . 9b coupled.

The nut coupling 903 , which is intended only for the APB function, runs on a nut 9 concentric raceway between the housing 301 and the cover-side nut half 9a , The Coupling of the nut halves 9a . 9b is by means of the lever 21 causes. The nut coupling 903 is by spring force from the pivot point of the nut 9 pressed out radially outward. The associated spring for the nut coupling, not shown here 903 relies on a raceway on the housing 301 from.

The bottom half of the nut 9b is similar for the APB and the APD function as the cover-side half of the nut 9a , again 7 can be seen. The difference is that the recess 913b for engaging the nut coupling 903 for the APB function on a smaller, to the pivot point of the nut 9 lying lying radius is arranged.

Both nut halves 9a . 9b each have a tangential point of attack for the receipt of Druckketteln 909a . 909b with nut feathers attacking it 907a . 907b , Depending on the function and coupling state, the nut halves 9a . 9b over the nut springs 907a . 907b and the pressure catches 909a . 909b individually operated and placed.

In APB and APD function is between the nut halves 9a . 9b a disk 9c arranged, which push through a matching square profile and thus the unauthorized coupling of the nut halves 9a . 9b prevented from outside. This disc 9c has a centric bore, over which a split square profile can be fastened by means of connecting screw. The square profiles on the bottom side and on the ceiling side remain independently rotatable.

In the 8th schematically illustrated cover-sided nut half 9a has for the APE function inside no receptacle for a square, but a receptacle for a Nutdrehteil 9d , The nut turned part 9d forms the connection between the ceiling 305 and the bottom half of the nut 9b , On the inside between the nut halves 9a . 9b is on the ceiling side a receptacle for a change 25 intended.

In the lock according to the invention 1 is a shift lever for the APB function 21 provided as he is in 6 is shown schematically. This comprises in the illustrated embodiment, two in the shift lever 21 guided drivers 2101 . 2103 , The drivers 2101 . 2103 be by spring force from the shift lever 21 pushed away or pushed out of this. In the shift lever 21 are two slots 2105a . 2105b provided, which is an up and down movement of the shift lever 21 but no lateral movement in the closing direction of the bolt 11 independently of this. On the back of the gear lever 21 There is a recess, not shown here, in which the bolt tongue 1107 can run free. The top of the gear lever 21 is designed with a radius so that the nut coupling 903 with locked back 11 is pushed up and the nut halves 9a . 9b coupled. Due to the radius, even with a rotation of the coupled nut halves 9a . 9b the nut coupling 903 held up so that they remain coupled.

The castle 1 also has a guard locking 23 on top of the bolt tongue 1107 , on the cover-side nut half 9a in the ceiling 305 and in the case 301 is led (see. 1 ). At the top of the tumbler 23 a spring, not shown here is provided, which is located on the housing 301 supports and the tumbler 23 pushes down. The stop forms the bolt shank 1103 , With retracted latch 11 is the bolt tongue 1107 the lower limit. In the upper area is a not shown here approach pin depending on the design as a right or left lock 1 attached on the front or back. When operating the nut 9 This approach pin is by a control cam in one of the nut halves 9a . 9b taken along and thus controls the up and down movement of the tumbler 23 ,

Embodiment APB function with top lock for single-leaf doors

Upon actuation of the cover-side nut half 9a , which is arranged on the panic side in this embodiment, with latch included 11 , z. B. by pressing a panic bar, the Nussarm attacks 901 on this page in the neckstick 705 , which in the fall shaft 703 is attached, and pulls the trap 7 back. About a guide pin 707 in the fall 703 is about the control cam, which is essentially through the recess 1301 is formed in the slide 13 for the top-locking this pulled down and unlocks the locking bar 15 the top latch before the trap 7 completely released. The cover-sided nut half 9a is doing of the ceiling-side nut spring 907a over a cover-sided printed matter 909a in the direction of a stop in the housing 301 pressed. The trap 7 gets from a trap spring 307 pushed outward. The locking bar 15 The top lock is by a slider spring 309 pushed upwards, taking the weight of the entire locking bar 15 including counteracts all the parts of the spring force. When pressing the panic lever 17 (eg via a handle, a pusher or a panic bar), the force of the nut spring must 907a , the falling feather 307 and the slider spring 309 for the locking bar 15 Overlocking the top.

With locked latch 11 and turning the cover-side nut half 9a is via a control curve 915a on the inside of the nut half 9a and a driver of the tumbler, not shown here 23 the tumbler 23 raised and gives the latch 11 free. The lower control arm 905a the nut half 9a grips with the outer contour on the neck pin 1701 the panic lever 17 and swings the panic lever 17 back. The bolt 11 is then about the power of the panic lever 17 withdrawn. The power transmission for closing the bolt 11 takes place via the outer contour of the panic lever 17 on a not shown here driver of the bolt shank 1103 , The bolt 11 when fully closed, locks into a nose of the detent lever 311 and is held there in the closed position. The locking lever 311 is with a spring 315 in the direction of bolt shaft 1103 pressed. Only when closing the bolt 11 by means of the lock cylinder 19 grabs the closing nose 1901 of the cylinder 19 in the locking lever 311 and pushes it against the force of the spring 315 downward. This is the bar 11 released and by the force of the latch spring 313 pre-joined.

When closing the bolt 11 becomes the tumbler 23 released and by one for the guard locking 23 provided spring, which is not shown here, pressed down. The bolt 11 can no longer be pushed back, since he is using a part of the bolt shaft 1103 from the tumbler 23 is blocked. The panic lever 17 is by the driver, not shown here in the bolt shaft 1103 always carried along and describes when closing the bolt 11 a rotational movement forward.

The at the bar 11 entrained shift lever 21 for the APB function can be with locked latch 11 the bottom half of the nut 9b with coupling. This is made possible by the two in the shift lever 21 provided driver 2101 . 2103 , These are spring-mounted and can be in the shift lever 21 Push. By precluding the lock cylinder 19 slides the locking nose 1901 over the sloping top of the lower driver 2103 and pushes it into the gear lever 21 into it. When the locking nose 1901 is over, drives the driver 2103 again by the spring force in its rest position out. When closing the latch 11 then grab the locking nose 1901 to the flat bottom of the lower driver 2103 and pushes the shift lever 21 up to the upper driver 2101 in the case 301 engages and so the shift lever 21 held up. At the same time is at the top of the shift lever 21 the nut coupling 903 pushed up and coupled so the two nut halves 9a . 9b , With coupled nut halves 9a . 9b can now also from the outside of the door the trap 7 and the locking bar 15 to be withdrawn from the top lock. Once the latch 11 is re-closed, engages the upper driver 2101 out of the case 301 off and on after the gear lever 21 moved to below, in its resting position. The nut coupling 903 is pressed down by a spring, not shown here and thus decouples the two nut halves 9a . 9b again.

With coupled nut halves 9a . 9b and actuating a handle (or pusher or panic bar), the nut coupling moves 903 with the nut halves 9a . 9b circular with. At the same time, the nut coupling becomes 903 through the gear lever 21 up to a nut rotation angle of approx. 15 ° in the two nut halves 9a . 9b held. Continue rotation until complete retraction of the trap 7 The holding function assumes a contour in the housing 301 ,

Alternatively, the trap 7 be released with zurückgeschlossenem latch by an electric door opener, which is installed in the strike plate of the door frame.

Embodiment APB function with top lock for double-leaf doors

For double-leaf doors with active leaf and fixed leaf is the lock 1 in the moving wing and a counter-box 27 provided in the passive leaf, as in 9 is shown schematically. The inactive leaf remains closed by default, but in case of panic operation it must release a corresponding handle, usually a panic bar, both the inactive leaf and the active leaf. That means that the lock 1 in the moving wing through the counter-box 27 is unlocked when actuated.

In contrast to the castle 1 for one-leaf doors, the castle has 1 for two-leaved doors a slightly modified construction of the bolt 11 , Here is the bolt tongue 1107 around a latch release 1109 added. The latch release 1109 works, if with vorgeschlossenem latch 11 the handle, in particular a panic bar, on the mating box 27 of the passive leaf is actuated. This is a bolt ejector 29 pressed, the first on the latch release 1109 meets and this towards the castle 1 pushes. The latch release 1109 is with the bolt tongue 1107 firmly connected. This hits in the back on a control cam of the guard 23 , The tumbler 23 is raised and the latch 11 can be pushed back completely by further movement of the Riegelauswerfers.

The trap 7 becomes essentially the same time as pushing back the bolt 11 through a trap ejector 31 in the counterbox 27 of the inactive leaf in the housing 301 pushed back and unlocked the door. In the counterbox 27 of the inactive leaf are the actions of the mechanics with the bar ejector 29 and trap ejector 31 It designed so that first the top and bottom locking 33 . 35 of the passive wing, then the latch 11 in the castle 1 pushed back and last the trap 7 in the castle 1 pushed back and possibly the locking bar 15 be confiscated.

Alternatively, the trap 7 with locked back 11 be released by an electric door opener, which is installed in the strike plate of the door frame.

Embodiment APD function with top lock for single-leaf doors

At a castle 1 with APE function, ie with a transformer switching function, as in 10 is shown schematically, is also a change 25 intended. Under "change" is in the context of the present invention, a device in the castle 1 understood the retraction of the trap 7 by means of key and lock cylinder 19 allows. The bottom half of the nut 9b is provided with a driver pin, not shown here, at which the change 25 attacks. The change 25 has a spring-loaded driver in the lower part 2501 , This spring-loaded driver 2501 gets from the closing nose 1901 of the cylinder 19 raised and thus pulls the trap 7 back. Is the locking lug located 1901 in the lower half, will when closing the bolt 11 the locking lever 311 raised and the latch 11 pre-joined. When turning back the key in the lock cylinder 19 grabs the closing nose 1901 of the lock cylinder 19 in the spring-loaded driver 2501 and picks up the bill 25 at. The trap 7 is thereby withdrawn, but what with vorgeschlossenem bolt 11 has no effect. Upon further turning of the key in the lock cylinder 19 reaches the closing nose 1901 a position in which they are above the spring-loaded driver 2501 slips and can be turned in the upper half. Then the closing nose hits 1901 on the tumbler 23 and pushes it up. This will be the bar 11 released and can continue turning the key in the lock cylinder 19 through the locking nose 1901 taken and until it engages in the locking lever 311 be closed back. Will the bar 11 closed again, the locking lug slips 1901 over the inclined surface of the spring-loaded driver 2501 and push it inside. Then there is the locking nose 1901 again in the lower half and the latch 11 can by triggering the locking lever 311 to be locked up again.

The panic function can in this embodiment of the castle 1 be activated from both sides, depending on which side of the handle, panic bar or push rod is attached, as only one of the nut halves 9a . 9b is provided with a square socket. If the handle, in particular a panic bar, actuated, for example, the cover-side nut half 9a rotated, first with a control cam in the lower control arm 905 the cover-side nut half 9a the tumbler 23 raised and the latch 11 is released. The outer contour of the lower control arm 905a acts on the attachment pin 1701 the panic lever 17 and turn it backwards. About a driver, not shown here of the bolt shaft 1103 pushes the panic lever 17 with it the bar 11 until it engages in the locking lever 311 back. At the same time, over the nut arm 901 and the attachment pin 705 at the fall shaft 703 the trap 7 and possibly the locking bar 15 the top latch retracts until the door opens.
