2- 15, 3 7 3 CS LOCKING IN FOUR HEAVY-DUTY AMiORTISE LOCK FOR 7--UILDIA

DIRECTIONS (five points) The invention relates to heavy-duty mortise lock for buildings locking in four directions (five points).

Many types of heavy-duty mortise lock are manufactured all over the world. It is characteristic to the locks nearest to the subject of our invention, that they lock and open with the bolt in one direction only. Various types of such heavy-duty mortise lock are available in the trade.

The common characteristic of the heavy-duty mortise locks up to the present state of technique and available in the trade is that all the known types lock in the same direction with t11-,e basic lock. The practice proves that these locks do not resist the different methods of breaking a door open, because they can be forced open for example with crowbar, or iron lever.

Due to the mentioned shortcomings of the heavyduty mortise locks, it became a practice the world over to fit the door with several and different types of supplementary safety locks.

This general practice, that in addition to the basic lock of the door, further safety locks are - 2 fitted, but even these do not give adequate safety against breaking a door open, because according to the widespread practice,the further individual safety locks are fitted together with the heavy-duty mortise lock on one side of the door.

According to the practice. the various locks fitted to one side of the door do not resist the forcible breaking in methods.since the door can be forced open with crowbar or iron lever. According to other similarly know breaking in methods, that part of the door where the heavy-duty mortise lock and safety locks are fitted, is being sawn round and thereby the door becomes open. The purpose of the invention is to realise a heavy- duty mortise lock for buildings locking in four directions (five points), which is capable to lock with a single lock mechanism built into the door- case in four different directions, i.e. together with the catch at five points with a single key.

The minimum two-directional locking of a wardrobe. or steel-door has already been solved.In the case of wardrobes. the locking takes place generally with vertical rods, while in the case of steel-doors the opening with key releases only the bolt that secures the separately actuated locking elements.

1 1 A heavy-duty mortise lock for buildings locking in four directions (five points) is not known which would be suitable for the following additional functions:

- Purpose of the catch traditionally used for doors is to snap into the slot of the door against spring pressure without key or other actuating device. The catch is released usually with key or handle (incidentally with knob). Such construction of the catch is also known, when a helping tongue is used to facilitate snapping in the catch. This tongue is built into the catch block.

- It represents novelty, that the catch is to be actuated separately on both sides, so that space is provided inside the lock for other structural elements. For this purpose, catch fork is fitted to the catch leg allowing free space in the vicinity of the catch leg for the divided hub, actuating the catch.

- The divided hub actuating the catch is always made to lock from the outside. Purpose of the catch is to prevent opening of the lock from the outside handle or knob. Essence of the structural solution is that two independently actuated hubs are used, in order that by turning the rectangular or shaped slot machined into the hub, the catch, or in given 7 case the locking bolt should be actuated through transmitting elements. With use of the divided hub, the opening with handle (or knob) from the outside or inside is independent. Further novelty of the invention is that the hub-fixing device can be changed over to right or left directional locking before the lock is installed. In this respect, construction of the hub-fixing device represents novelty.

- The use of auxiliary catch and catch-wedge is customary in doors fitted with locking catch, where actuation of the outside handle (knob) is inhibited, and the locking catch must resist the attempts to open the door by force. In locked position of the door, the auxiliary catch lowers into the end-face of the lock mechanism, therefore it cannot be forced open. since coacting with the catch wedge, it wedges up the locking catch. Further novelty of the invention is that the wedge fork coacting with the auxiliary catch is capable to wedge up the catch fork by way of the catch wedge coacting with the catch fork.

- Bolt of the building lock according to the invention is actuated with threaded cylinder lock (mortise.lock) or from inside knob. The boltactuating 1 1 t fork is conventional. it can be directly actuated from the fork knob by way of the rectangular or other shaped hole.

- Multi-directional locking rod actuated together with the bolt. In the traditional wardrobe locks generally two-directional and in steel door locks three-directional locking rods are actuated with or without bolt. There are solutions where the rods are actuated independently,the lock fixes only the lock -position. The bolt itself may represent a fixing point. The lock mechanism in wardrobes actuates two rods.Inrespect of the lock mechanism according to the invention it can be regarded as novelty that simultaneously with actuation of the locking bolt, both the bolt and rods can be moved in different directions by using identical actuating element. Structural novelty is the use of rod-actuating plates fitted on rod-actuating disc adjoining the locking bolt.

- Lock which releases the threaded cylinder lockactuated bolt and rods is not known. Novelty of the solution: bolt actuation from threaded cylinder lock or inside knob was realized by multi-directional locking rods in coaction with the bolt.

- Handle actuated catch withdrawal and release of bolt, or locking rods (panic function).

- In case of several or combined functional locks some standards specify to release the various locking modes of the lock mechanism by a single movement from the inside, e.g. in emergency situation. In order to satisfy these standard specifications, the novelty of the lock mechanism according to the invention is that the other end of the catch actuating lever coacting with the hub is connectible with the emergency opening lever mounted on the bolt-actuating t fork in closed position of the bolt-actuating fork. Thereby the catch- actuating lever forced to displacement by the hub. pulls the catch to open position, and at the same time the bolt-actuating fork by turning the emergency lever mounted on the boltactuating fork. This way. the locking bolt and the connected locking rods are moved to normal - omen position.

The invention relates to a heavy-duty mortise lock for buildings locking in four directions (five points), where preferably a stop buffer, screw houses, perch stud, catch guide are fixed and a threaded cylinder lock adapter-fixing plate is arranged in the lock casing. Catch wedging spring with ring fastener may be mounted on the screw house. A bolt pin may be pressed into the bolt 1 1 in the lock casing. The catch assembly unit for ing the catch of the lock mnechanism preferably consists of the catch head. catch adapter, lock pin, catch shaft. catch spring washer, the spring, split matching sleeve and catch leg. A tub adapter may be arranged in the hole of the hub interconnected with the handle. The catch actuating assembly unit is preferably carposed of a spring, catchactuating levers, ring fasteners, fork shaft Tnounted on the stop buffer and the upper catch-actuating lever. The bolt-actuating element of the lock mechanism may be formed by the bolt-actuating fork fitted with distance levers and emergency opening lever. The handle fixing mechanism of the lock may have an asse.-.'.)ly un--t consisting of handle fixing insert. its shaft, lock pin and spring.

Novelty of the heavy-duty mortise lock for buildings locking in four directions according to the invention is that the catch wedging fitting has catch wedging forkp fitted with catch wedging adapter with catch wedging pin. The catch assembly unit may consist of a forked catch leg, wedging plate spring, catch wedging plate and fork pin. The rod-actuating mechanism may include a rod-actuating disc placed on the hub adapter, rodactuating plates and binding pins. The catch-actuating structural elements may be complemented with springs, 1 catch-actuating levers and -ring fasteners. U"he hub fixing assembly unit may be formed by the hub fixing levers and shoulder pin.

The most important advantage of the heavy-duty mortise lock locking in four directions according to the invention are the following:

- The door can be locked in all directions with the aid of a single keyactuated lock mechanism.

- It satisfies the statical and dynamic requirements of all building locks.

- It satisfies the conditions of the panicfunctional opening specified in the standards of each country.

- In respect of protection against breaking in, the catch fixing and limiting the handle opening with divided hub are solved in a novel way.

1 The reference numbers used in the drawings designate always the same structural element.

Fig.l. shows (on top right side) the parts in the lock casing 1: Stop buffer 2, screw houses 3,4,,5, perch stud 7. bolt pin 8 and catch guide 41. The side 62 and front plate 63 are screwed to the lock casing 1. The assembly along the tracelines marked in the Fig. is the following:

The insert-fixing plate 60 fits into the space machined in the lock casing. The catch wedging spring 32 goes on the screw house 4 secured in position by ring fastener 11. Bolt 35 is in space 1/a in the lock casing with bolt pin pressed in it. The assembly unit consisting of catch wedging fork 31, catch wedging spring 32, catch wedging adapter 33 and catch wedging pin 34 mdunted in the place confined by space 1/b. The assembly unit composed of catch head 20, catch adapter 21, lock pin 22, catch shaft 23, catch spring washer 24, spring 25, split matching sleeve 26, catch leg 27, wedge plate spring 28, catch wedging plate 29, shoulder pin 30 is in the place confined by space 1/c and catch guide 41. In space 1/e of the lock casing 1 is one hub 18, in the hole of which is the hub adapter 19, and the assembly unit col-posed of rod-actuating disc 12, rod- actuating plate 1, 13# fixing spring 14, rod-actuating plate 11, 15, rodactuating plate 111..16 and binding pins 17 is mounted on the hub adapter 19. Another piece of hub 18 is mounted on the former assembly unit. On the screw house 5 of the lock casing 1 adjoining the catch guide 41 are the following mounted: spring 10, catch-actuating lever 9. two position fixing ring fasteners 11, catch-actuating lever 57 and spring 58. In the hole of stop buffer 2 is the collared shaft 40 surrounding the upper catch-actuating lever 39. In space 1/f of thelock casing 1 is the assembly unit composed of bolt- actuating fork 37, distance washer 36, and emergency opening lever 36 the position of which is secured by bolt spring 42 mounted on bolt 35. In space 1/d is the assembly unit composed of the hub fixing lever 1. 43, hub fixing lever 11 44, shoulder pin 45, hub fixing adapter 46, lock pin 48 and spring 49 so that the hub shaft 47 secures position of the assembly unit.

The complete lock mechanism assembled as described above is closed by screwed-on cover plate.

Fig.2a-2g present the drawing of the assembled lock mechanism according to the invention, the elements of which were partly described in connection with Fig.l. Further structural elements shown in 1 Fig.2a-2g are the following:

Hub fixing release lever 51. pin house 52, forked pin 53, release lever 54, release insert spring 58, catch spring 56 mounted together with cover plate 61 are shown in Fig.2g. On the faceplate 63 of the lock - as shown in Fig.2a - is a protection foil 64. Screws 65-68 as further fixing elements are shown in Fig.2a-2g.

Drawing of the assembled lock mechanism is shown in Fig.3a-3g, the catch and its actuating element in normal position are narked with thick line. Representation of the normal position is the same as the arrangement shown in Fig. 2a-2g, the thick line indicates the normal, i.e. locked position of these structural elements in relation to the open position shown in,Fig.4a-4g.

Operating mode of the structural elements shown in Fig. 3a-3g is the following: when turning the hub 18 clockwise or anticlockwise, the catchactuating lever 9 moves towards the rear side of the lock simultaneously pulling back the catch leg 27 assembled together with catch head 20, catch adapter 21, lock pin 221 catch shaft 23 and the split matching sleeve2e.

The position actuated as described above is shown in Fig. 4a-4g.

1 When the turning force of the hub 18 is stopped, the catch guide 41supported spring 25 presses the catch assembly to starting, normal position. In this case again the operating position is brought about as shown in Fig. 3a-3g.

Drawing of the assembled lock is shown in Fig. 5a-5g, marking the catchactuating divided hub with thick line in the open position of the lock. The catch-actuating divided hub functions always with locking on the outside. The divided hub 18-locking mechanism in normal position allowing the separate actuation, i.e. turn of both elements of the hub mechanism consisting of two hubs 18 is shown in the drawings (see explanation of Fig.3a-3g.). Upon pressing the upper edge of the hub fixing adapter 46 turnin round hub shaft 47 from the normal position, the assembly unit composed of hub fixing lever 1. 43 interconnected through shoulder pin 45 with the hub fixing lever I. 46, hub fixing lever 11. 44 and shoulder pin 45 move on, and the rear edge of hub fixing lever 1.43 is wedged into the slot of hub wedge 18. This way turning of the hub 18 from one side of the lock is inhibited. This operating condition is shown in Fig.6a-6g presenting the drawing of the assembled lock mechanism marking with thick line the cattt,--wtoting - 15 divided hub, the locking mechanism in inside locking position, while Fig.7a-7g show the catch-actuat ing divided hub in outside locking position of the lock marked with thick line.

As shown in Fig.l., the assembly unit composed of hub fixing lever 1.43, hub fixing lever 11.44 and shoulder pin 45. with the removal of lock pin 48 can be assembled also by turning at 180 0 in the hub fixing adapter 46. Its purpose is to adjust the position K of the hub fixing lever 43 in the lock according to the required side. thus the divided hub 18 can be locked.

Fig.8a-8g show the lock in assembled condition. marking with thick line the open position of the catch locking auxiliary catch and catch %,.,edge. The catch assembly (see Fig.3a-3g). the wedging plate spring 28 and catch i..,edging plate 29 mounted on the catch assembly, as well as thecatch wedging assembly unit composed of the catch wedging fork 31, catch wedging spring 32, catch wedging adapter 33 and catch wedging pin 34 are shown in normal position.Upon closing the door, the counterplate E fixed in the door-case presses the catch wedging assembly unit against the catch wedging spring 32 into the lock mechanism by moving the catch wedging adapter 33.

1 - 16 In this position the wedging plate spring 28 lifts the catch wedging plate 29 and by turning round the shoulder pin 3o it arrives at the machined part of the catch wedging fork 31. This way, unauthorized entry - that would happen by pressing back the catch assembly unit with a tool between the door and its case - is not mossible because of the fixing position of the catch wedging plate 29. This fixed position is shown in Fig.9a-9g. From this fixed position,, the catch assembly can be released as described in the explanation of Fig.3a-3g.

Fig.10a-10g show the lock in assembled position, marking with thick lines the bolt-actuating fork, rod-actuating disc connected with the lock nechanism and the adjoining rod-actuating plates in open normal position. Purpose of the actuation is to drive the multidirectional locking rods coacting with the bolt. The drawing shows the bolt 35 bolt-actuating fork 37,- bolt spring 42, rod-actuating disc 12 connec ted with the bolt 35 and the assembly unit in normal position, composed of the rod-actuating plate 1. 13 rod-actuating plate 11. 15 and rod-actuating plate 111. 16 joined to the rod-actuating disc with binding pins 17. Elhen the bolt- actuating fork 37 is turned anticlockwise (about 110 0), the bolt 35 is 1 1 pushed to locking position. Lt the same time the pos tion shape machined on the bolt - not engaged with the slot of the rod-actuating disc 12 - turns clockwise. Consequently, the rod-actuating plate I. 13 moves in opposite direction to the faceplate of the lock mechanism, the rod-actuating plate 11. 15 moves upwards and the rod-actuating plate 111. 16 downwards. The 110 0 turn of the rod-actuating fork 37 means 55 0 symmetrically to the right and left from the vertical centreline of the lock mechanism. These extreme positions are secured by the bolt spring 42, and the bolt spring fork 37 secures the open or locked position of the bolt 35 and the adjoining rodactuating assembly in the positioning shape machined at 450 to the right and left from the vertical syr.metry axis on the bolt 35.

Fig.lla-llg illustrate this locked position. As shown in the drawing, in locked position the bolt 35 wedges up the catch head 20, and thus the catch head 20 forms the fifth locking point when the mechanism is completely locked. The locked position of the locking mechanism is released by the clockwise turn of the bolt-actuating fork 37. The fork 37 can be turned by the knob arranged in the slot of thebolt-actuatina fork 37.

Y 1 Fig.12a-12g present the lock mechanisrin, i.Ihere the fully locked position, i.e. actuation of the multidirectional locking rod in coaction with the bolt is marked with thick line.

Fig.13a-13g show opening of the lock with the slide-carrier "T" of the cylinder leg insert. By turning the slide-carrier "T" anticlockwise - with key from outside of the door - the slide-carrier "T" turns the boltactuating fork 37 clockwise. As a result, the bolt is released as described in connection with Fig.11a-11g. The upper catch-actuating lever 39 coacting with the catch of the bolt 35 turning around the collared shaft 40, brings the upper catch-actuating lever 39 to catch opening position. Upon further anticlockwise turn of the slide-carrier "C, it presses the adjoining shoulder of the upper catch-actuating lever 39, and leg of the upper catchactuating lever 39 pulling back the catch leg 27 brings the catch assembly to open position.

Fig.14a-149 illustrate this position, i.e. the open position of the catch from the open position of the bolt shown in Fig.13a-13g with the use of the cylinder insert.

Fig.15a-159 show the function of the joint catch withdrawal and release of the bolt and locking rods 0 - 19 actuated from the inside with handle or knob (panic function, i.e. opening the lock with a single movement). Turning the knob or handle- actuated hub 18 clockwise or anticlockwise, the catch-actuating lever 9 moves to opening direction (towards the rear wall of the lock mechanism). As a result a) the catch mechanism moves to opening direction (see Fig. 3a-3g) and at the same time b) the emergency opening lever 38 mounted in the lock - which is wedged together with the bolt-actuating fork 37 - turns clockwise: upon the simultaneous turn of the emergency opening lever 38 and boltactuating fork 37, the locking mechanism is opened (see Fig.12a-129), whereby the lock mechanism can be brought to fully open position by a single movement which satsfies the requirements of panic opening, or not opening.

In the annexed claims reference numbers have been used purely by way of example in order to facilitate comprehension, but it is hereby declared that absolutely no limitation of scope whatsoever is intended thereby.
