The invention deletes to an additional lock for a door or a window, said lock comprising an operative connection between a displacement plate of the additional lock and a corresponding contrei mechanism of a main lock, end'conse^uentiy said additional lock can be centreiled by said mein lock, wherein the additional lack comprises a housing (1} having a looking hook that is pre^etressed against its stading position and is mounted in said housing in a rotatable manner and when a locking piece bolt enters a recess of the housing said locking hook can be rotated into Its looking position.

Prior art "There is a plurality of possibilities tor the configuration of additional locks for doors or windows having multipoint looking arrangements. In general, bars that can fee displaced parallel to the profiled strip or that can be displaced outwards are used, said fears engaging into corresponding recesses in looking pieces.

Furthermore, locks having rotary latch locking arrangements are known and are frequently used by way cf example In the motor vehicle industry. A lock of this type Is disclosed fey way of example In DE 2345890 Aí, in the case of conventional rotary letch looking arrangements, the locking arrangement is provided, as Is also disclosed in this publication, by means of a pivot lever that cooperates with a corresponding edge or recess on the looking hook and In the locked state blocks said locking hook from rotating in the opening direction. A construction of this type is fault-prone since the two rotatable paps that engage Into one another, the looking hook end pivot lever, can jam easily when subjected to load conditions. So that the locking security Is ensured, it is necessary either to provide complicated gearing mechanisms for actuating the pivot lever or to produce the geometries between the operative surfaces of the locking hook and the pivot lever with particularly narrow tolerances In order to render possible both a secure locking arrangement as well as a simple unlocking amangsment This increases the production costs, which can be tolerated when said look is being used as a main lock in the case of fey way of example a motor vehicle but would turn-out. to fee toe high for the use of a lock of this type as an additional leek on a doer or window, DE 10 £000 Ô4S039 AI oiseioses sí rotary latch tor doors or windows that composes a pivot sever and a looking hook In a Similar manner to the above-mentioned looks, said pivot lever sind latching hook securing a holt that has entered Into the rotary latch and therefore locking the rotary latch. In thio ease there is also the disadvantage that the construction le bolt-prone and must he produced with particularly narrow tolerances.

Short description of the levenden it is consequently the object of the present invention to eliminate the above-mentioned disadvantages and to provide an additional lock that offers the advantages of a rotary latch locking arrangement but Is nevertheless cost-effective to produce and offers a high degree of locking security.

This object ts achieved by virtue of the fact that the displacement plate can he displaced essentially parallel to the longitudinal axis of the housing and said displacement plate Is pre-stressed In the direction of its locking position, and that the displacement plate comprises a control contour that extends at least In sections at an Incline towards the movement direction of said displacement plate and that a control bolt of a locking piece is guided in said control contour, being displaceable essentially normal to the movement direction of the displacement plate, so that. In the locking position of the locking hook and consequently aiso the iocking position of the displacement plate an edge of the locking piece lies against a shoulder of the locking hook and blocks said locking hook fre-rn rotating in the direction of the stading position. The opening and locking mechanism of the additional look can therefore be achieved by means of only two components that can move in a linear manner and that cooperate with the locking hook, which on the one hand is particularly cost-effective to produce and on the other hand otters a particularly high degree of locking security. in accordance with a further feature of the invention, it is provided that the shoulder of the locking hook Is configured in an at least two-stepped manner, as a result of which at least two points that lock with the edge of the locking piece are provided. Alternatively: the edge of the looking piece can ba configured in an at least two-stepped manner As doors warp to a certain extent during the course of time or in dependence upon the weather conditions and time of year, it is possible in each situation to provide a secure looking arrangement of the additional lock by means of multistep looking points end it is possible to compensate the tolerances that occur.

Furthermore, If is a feature of the present invention that the operative oonnection between the mein teek and the displacement plate of the; additional leek is formed fey mesns of a cable pull, wherein the polling direction of the cable pull is opposite the direction in which the displacement plate is pre-stressed. A construction having a cable puli offers the advantage that an essentially smaller application of force is required in comparison to a conventional construction having displacement rods, if is only necessary to overcome the forces of the ;pre-stressing arrangement of the displacement plate of the additional look and it is not necessery to apply additional forces to raise a dlsplecement rod. A further advantageous feature of the invention is that a further cable puli is connected to the dispiaoement plate on the opposite end of whore the cable puli to the main lack <s located, said further cable puli being guided cut of the housing and being connected to further additional locks on the aide of the additional loch that is remote from the mein lock. As a consequence, it is possible to connect an arbitrary number of additional looks in series depending upon the application,

Finally, a feature of the present invention is that the displacement plate can be moved byway •of the cable pull into an opening eodi position and can be locked by way of the main lock in said opening and position, end that a detent that can be displaced essentially normal to the movement direction of the displacement plate Is provided in the displacement plate, said detent being pre-stressed in the direction of Its extended position by means of a spring, and being in engagement in the opening end position of the displacement plate and in the locking position of the locking hook with a latching shoulder of the locking hock, said detent latching the locking hook in a resilient manner in the locking position. Often, locks are provided with a so-called “day setting", wherein in the main lock the latch is generally locked in the withdrawn position, end it is possible to easily open and; close a door at any time. Functions of this type are often desirable in the case cf doors in public buildings or businesses, If the relovent door comprises additional locks, said locks are typically also locked in the opened position, it is possible by means of the above-mentionedfeature that the locking book latches by means of the provided detent In its locking position when e dooms closed but said looking hook een be moved hack into its starting position with a small application of feree by means of overcoming the resilient force of the locking detent, as a: result of which If is possible to open the door in a simple manner. This offers the advantage that. the door cannot be easily pushed open by way of example as a result of wind of the like, however if fa not necessary for a user to actuate a door handle and the door can be pushed open with a email application of force.

The additional lock that is lllustrafed in Fig, 1 to the form cf an additional lock having a rotary latch lock comprises a housing 1 that is Illustrated with a removed :uppor plate for a better view. A leaking hook 2 that is mounted in a pivotable manner on an rotary axle 24 is located in the housing i, said locking beck being pre-stressed against its -starting position by means of a spring 4 (cf. Fig. 2). A displacement piafe 3 that is likewise pre-stressed against Its locking position by means of a spring § (cf Fig. 2) Is arranged parallel to the longitudinal side of the housing 1 in a movable manner. The displacement plate 3 comprises receiving arrangements 16 for mounting puli cables (not illustrated) that are guided out of the housing 1 through openings 17 and are connected to the main lock or further additional locks. A detent 18 is pre-stressed in a further receiving arrangement 2.0 in the displacement plate 3 by means of a spring 19 in the direction of the locking hook 2. When the door or window is being closed, the additional lock makes contact with a locking piece 7 with a locking piece bolt 8 that enters into a recess 8 of the housing "s and consequently enters -nto a recess 9 In the locking hook 2 and rotates the locking hook 2 into its locking position. 'The locking piece bolt 8 -s arranged in such a manner that it can be displaced vertically in order to compensate for positional inaccuracies of the locking piece. The inlet incline o? the recess 6 of the housing l brings the locking piece bolt 8 Into the correct position.

Fig. 2 Illustrates a plan view of the additional lock in Fso 1 In the storting position. The displacement piste 3 is pressed by means of the force of the spring 5 in the direction of the looking .position, wherein a locking piece lí that can be displaced normal to the movement direction of the displacement plate 3 engages with a control belt 12 in a contour W of the displacement plate 3 The contour 10 Is arranged at least in sections -nchned towards the movement direction of the displacement plats 3, as a result of which the looking piece 11 is pushed in the direction of the locking hook 2. Since the locking hook 2 is in the starting position, the locking piece 11 lies against the Side of the locking hook 2, as a result of which the displacement plate 3 cannot entirely move into the locking position, if a locking: piece belts enters into the recess 8 of the housing 1: the locking hook 2 starts to rotate against the force of its spring 4 m, the direction of the locking position, wherein the locking piece holt 6 slides into a recess 9 of the seeking hock 2.

When reaching the locking position, as Is Illustrated in f’ig, 3, an edge "13 of the locking piece 11 slides over the shoulder 14 of the locking hoek 2, as a result of which the displacement plate 3 can move further In the direction of the locking position and therefore the locking piece 11 can move further In the direction of the- locking hook 2. The lock Is locked by means of the shoulder 14 of the looking hook 2 lying against the edge 13 of the blocking piece IT. The shoulder 14 can also be configured in a muitlstepped manner, wherein In the illustrated exemplary embodiment a second step 15 Is provided. In the oase of the completely locked position the edge 13 of me locking piece 11 lies against this second step '15 However, since In practice tolerances occur, for example as a result of a door warping, it is still possible by means of providing a muitisiep shoulder io achieve a secure locking position even in the case of larger tolerances, in or’der to open the addltionai look, the cable pull is actuated by way of the locking mechanism of the main leek, as a result of which the 'displacement plate 3 is pulled against the fércé of the spring 5. As a consequence, the locking piece 11 is also pulled away from the locking heck 2 by way of the contrei bolt that is guided in the contour 10 and releases said locking hock se that it can return to its starting position. in the position illustrated in Fig. 4, the displacement plate 3 is located in an opening end position in which sold displacement plate can be locked by way of the cable pull by the main tóp âs â result of which a day setting is achieved; for the additional look. Thé Peking hook 2 is located in the; starting position, in this position, a detent 18 that is pre-stressed by means of a spring 18 and can ha moved normái to tha movement direction of the dispieoement plate 3 comes to lie In the region of the locking hook 2. if the door or window is ölesed, tha looking hook 2 thus rotates, as. a result of which tha datant 18 is pushed beck by means of a aide surface- of the looking hook 2 against the force of its; spring IP In its receiving arrangement 20, as is Illustrated in fig, 5,

When reaching the locking position of the locking hook 2 in accordance with Fig. 8, the detent slides over e latching shoulder 21 en the latching hook 2, as a result of which If is held in this position. When the additional look Is being opened, if is only necessary to puli in toe opening direction and to overcome the force of the spring 19 of the detent 18, whereupon the-additional lock Is released. Consequently, even in the day setting the additional lock can be used to securely snap in the sloor or window, wherein furthermore It Is possible without the use of a key or door handle to open the door or window merely by means ef pulling the door or window.

Figures 7 end 8 Illustrate in detail the displacement piafs 3 that comprises on one side the recesses 18 for mounting pull cables and also the receiving arrangement 20 ter the detent 18, The conteur 10 tor the control bolt 12 of tile looking piece 11 is located on the oppositedying side, and a receiving arrangement 22 for the spring 5 Is also located on said opposite-lying side,,

Fig, 2 illustrates the locking hook 2 that comprises a recess 9 for receiving the looking piece bolt 8, A receiving arrangement 23 for the spring 4 is arranged about the rotary axis 24, The shoulder 14 tor locking the looking books Is located approximately opposite the recess-8; said shoulder in the illustrated exemplary embodiment comprising a second step 16.

Finally, fig, 10 Illustrates the locking piece 11, which is provided with a guiding groove 23 that is guided on a corresponding rib in the housing. Furthermore, the control bolt 12 that engages into the control contour 10 in the displacement plate 3 is located on the locking piece IT, and the edge 13 that cooperates with the shoulder 14 or the second step 15 of the looking hook in the locking position is also Ioeaied on said looking piece.
