Description

Technics? field pool j The invention relaioe to en additional lock tor a door or a window, said additional look comprises an opereiiva connection between a displacement piste of the additional lock to a corresponding control mechanism of a main lock and consequently can be controlled by said main lock, wherein; the additional lock comprises: a housing having a locking tab that Is rotatably mounted in said housing and is pre-stressed: against the starting position of said looking tab and said locking tab is able to rotem into Its looking position as a locking piece bolt impinges in a recess of the housing.

Prior art :(0002] For doers or windows compnsing multiple looks, there is a multiplicity of options for designing additional looks, For the moat part, locking bars are .used which can be pushed out or displaced In parallel with the face plate and engage Into corresponding recesses in locking points, (0003] h'Pdharmorsk locks comprising rotary latch locks are known, e,g< In DB 102009048839, which are frequently used e.g, in the automotive industry, but are also -used In conventional door locks. Often, locks are provided with a so~ea|ied "day position", wherein corresponding latches or locking fears· are stopped in the refracted position in the lock, and a door can be easily opened and closed at any time. Such functions are often desirable in doors In public buildings or shops, Should the door in question hava additional locks, they ere typically also locked in the open position. An exemple of .such a look having a day position end tcUry latch look is shown ln DE 10201004058? AI. Locking is effected either by means of a handle or actuator. 10004]: A disadvantage of the known solutions Is that In the day position, the function of the latch is completely deactivated and therefore there is absolutely no purchase, between the locking point and rotary latch. Therefore, the door can be opened without any resistance, whereby it is easily poshed open even In undesirable situations, such as in windy conditions. The use of rotary latch looks in revolving or sliding doors also gives rise to the problem that in the last couple of millimetres to the locking point relatively large tolerances are often present because the way the door Is hung means that the face plate does not extend one hundred percent perpendlculerly and as a result, specifically when closing the door, a certain pulling: force of the rotary latch is required In order to keep the door in the locking position. However, in the case of conventional locks having a day position, the rotary latch would not provide any retention at all, whereby ín meny situations the dead weight of the door would cause It to slide-out of the looking point and' therefore said door would always be open by- a gap when the day position is activated.

Brief description of the invention [0<X>S] Therefore, It is an object of the present invention to provide en : additional lock .having an: improved day position, which overcomes the aforementioned disadvantages and which is simple and cost-effective to produce.

[0006] In accordance With the Invention, this object is achieved In that the displacement plate can be displaced essentially parallel to the longitudinal axis of the housing, can be moved by way of the operative connection by the main look Oom a starting position Into an opening end position and can be stopped In said opening and position by way of the main lock, and in that a latch, which can be displaced in the direction that is essentially ncrmal With respect to the movement direction of the displacement plate, is provided in the displacement piste, sasd letch being pre-stressedi by means of a resilient element against its extended position, .and when the displacement piste Is in the opening end position and when the locking tab is in the locking position, said latch is In engagement with a latching shoulder of the locking fab and latches said looking lap In the locking pbsifioh in a resilient manner. The aforementioned feature ensures that although, when closing a door, the locking tab latches m its locking position by means of the provided latch, if can then be moved beck to Its starting position with a smell application of force by overcoming the resilient force of the locking: letch, whereby the door can be easily· opened. This provides the advantage that the door cannot easily be pushed open e.g. as a result of wind or the like, but a user does not have to actuate a door handle to open tbs door and can push the door open by applying small amount of force. The force of the resilient element of the latch can be selected depending upon use such that the corresponding door moves reliably info the lock and at the same time is easy to open, [ÖÖ07] It is a further feature of the Invention that the displacement plate is pre-stressed against the locking position of said displacement plate and comprises a control contour that extends at least In sections at an incline with respect to the movement direction of said displacement plate, a control bolt of a locking piece that can be displaced essentially perpendicular with respect to the direction of movement of the displacement plate being guided >n said control contour so that, when the locking tab is in the locking position and consequently also the displacement plate is in the looking position, an edge of the locking piece lies against a shoulder of the locking fab and blocks said locking tab from rotating In the direction of the starting position. When the day position is deactivated, the opening and locking mechanism of the additional lock can thus he achieved by means of lost two linearly moved components which cooperate w-th the locking tab. which, on the one hand, is very favourable in terms of production end. on the other band, offers a high level of locking security. iOOOdj it is else e feature of the present invention that the shoulder off.be locking tab is embodied as having at least two steps, as a result Of which at least two locking points are produced with the edge of the locking piece. Alternatively, the edge of the locking piece can also he embodied as having at least two steps. Since a certain distortion arises in doers over the -course of time and/or in dependence upon weather conditions and the season, multi-step locking points mean that in any situation secure locking of the additional lock can take place and the tolerances which arise can be compensated fon [0009] According to a further feature of the invention, provision is made that the operative connection between the main lock and the displacement plate of the additional look is formed tsy means of a cable pull, wherein the pulling direction of the cable pull Is opposite the direction in which the displacement plate is prestressed. A construction with a cable pull offers the advantage over a conventional construction with: thrust rods that a substantially lower application of force Is required. It is necessary only to overcome the forces of the pre-stressing of the displacement plate of the additional look and no additional forces nave to be applied to lift a thrust rod, 100101 Ä further feature of the invention Is that on the displacement plate on the opposite end of the cable pul! to the mein look a further cable pull Is connected to the displacement plate and said cable pul! is guided out of the housing and is connected to further additional locks on the side of the additional lock that is remote from the main lock, if is thereby possible to connect any number of additional locks In series, depending on the use.

Brief description of the figures of the drawing [0011] The invention will now be explained in more detail with the aid of the accompanying drawings In which figure 1 is a perspective view of an additional lock in accordance with the invention having a locking point and with the housing cover removed; figure 2 shows the additional lock of figure 1 in the opening end position when the day position is activated and with the locking tab in the starting position; figure 3 shows the additional look of figure 2 in the opening end position when the day position is activated with the locking tab in an intermediate position; figure 4 shows the additional lock of figure 2 In the opening end position when the day position -s activated with the locking tab latched m the locking position; figure 5 shows the additional look of figure 2 in the starting posihon wkh the; day position deactivated; figure 6 shows the additional look of figure 2 -n the looking position; figure 7 is a perspective view fron; one side of the displacement plate: figure 8 is a perspective view of the other side of the displacement piste; figure 9 is a perspective view of the locking tab, and figure 10 is a perspective view of the locking piece.

Description of the embodiments (0012] The additional lock illustrated in figure 1 in the form of an additional locking device with a rotary latch lock comprises a housing i which is illustrated with the top plate removed for clarity of view. The housing 1 contains a locking tab 2 pivotably mounted on a rotary axis 24, which locking tab Is pre-stressed against its starting position by moans of a resilient element:4 (see figure 2). A displacement plate 3 which is likewise pro-stressed by means of a resilient element 5 (see figure 2} against its locking position is movabiy disposed in parallel with the long side of the housing 1. The displacement plate 3 comprises receivers If for the suspension of puli sables (not shown) which are guided out through openings 1? in the housing 1 end are connected to the main look and/or further additional looks, in a further receiver 20 in the displacement piste 3, a latch 18 is pre-stressed In the direction of the locking tab 2 by means of s resilient element 19. When the door or the window is being closed, the additions! lock impinges on a locking point 7 with a locking piece bolt 6 which in sc doing enters a recess 8 in the housing 1 and consequently a recess 9 (see figure 2) in the locking tab 2 and in so doing rotates the locking tab 2 info Its looking position. The locking piece bolt 6 Is disposed in a vertically displaceable manner in order to compensate for positional inacoutsoies in the locking piece. The run-in slope of the recess 3 of the housing 1 brings the looking piece bolt δ to the correct position, (0013) in the; position illustrated in figure 2, the displacement plate 3 is in an opening end position in which $t can be stopped by means of the cable puli from the mein lock, whereby a day position for the additional lock is achieved. The locking fab 2 is located in the starting position, A latch 18 which is pre-stressed by means of a resilient element 19 and can move norma! to the movement direction of the displacement plate 3 comes to lie in the region of the lock-no tab 2 in this position. (Ö0141 If the door or the window is now locked, the locking tab 2 rotates, whereby the taton 18 is pushed beck into its receiver 20 through a side surface of the locking tab 2 against the force of its resilient element 19, as shown in figure 3.

[001 bj Upon reaching the locking position of the locking fab 2 according Io figure 4, the latch slides over a latching Shoulder 21 on the looking tab 2, whereby this looking fab Is held in this position, Upon opening the additional look, it ss merely necessary to puli In the opening direction and to overcome the force of the resilient element 19 of the latch 18. whereupon the additional dock is released. Therefore, the additional lock can also serve In the day position to provide a secure shap-in action of the door or of the window, wherein opening is then also possible merely by pulling the door or window without use of a key or a door handle, (0018] Figure S shows the additional look of figure 2 In the starting position when the day position is deactivated, The displacement plate 3 is pressed in the direction of the looking position by the force of the resilient element 8, wherein a looking piece 1 f which can be displaced normal to the movement direction of the displacement piste 3 engages with a control bolt 12 in a contour 10 of the displacement plate 3,, The contour 10 is disposed at least in sections at an inclination with respect to the movement direction of the displacement plate 3. whereby the locking piece 11 is pressed in the direction of the looking tab 2. Since the locking tab 2 is in the starting position, the locking piece 11 lies against the side of the locking fab 2, whereby the displacement plate 3 cannot fully reach the locking position as weil. If a locking piece belt 8 now enters the recess 3 of the bousing 1, the locking tab 2 begins to rotate against the force of its resilient element 4 in the direction of the locking position, wherein the locking piece bolt 8 slides into a recess 8 of the looking tab 2- (0017] Upon reaching the locking position, as shown in figure 8, an edge 13 of the locking piece 11 slides over the shoulder 14 of the looking tab 2, whereby 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 tab 2, The lock is locked because of the shoulder 14 of the locking tab 2 lying against the edge 13 of the looking piece 11,

Tbq shoulder 14 cpn also bo embodied as having multiple steps, wherein, In the illustrated^ exemplified embodiment, a second step 13 is provided In the full locking position the edge 13 of the locking piece 11 lies against this second step 15, However since in practice, tolerances arise, e g, owing to the distortion of a door, the provision of a multi-slop shoulder means that a secure looking position can be achieved even m the ease of relatively large tolerances. (00i81 In order to open the additional lock the cable puli is operated vis the lock mechanism of the main lock, whereby the displacement plate 3 is pulled against the force of the resilient element S In this way, by means of the control bolt guided m the contour 18, foe fork-ng piece ; is atso puled away from the fooking tab 2 and releases sanie in order to be able to return to its starting position.

[0019] Figures 7 and 8 show in detail the displacement plate 3 which, on one side, comprises the recesses 16 for suspension of pull cables and the receiver 20 tor the- lefoh 18, Locates prs the opposite side is the contour 1.0 for the control bolt-12 of the looking- piece 11 and a receives 22 for die résilient element δ.

[ÖÖ20] Figure 9 shows the looking fab 2 which has a recess 9 to receive the looking: pie« holt 3, A receiver 23 for the resilient element 4- is disposed around: the rotary axle 24. The shoulder 14 for looking the looking tab 2 is located approximately opposite the recess & the shoulder comprising a second step 15 ;n the illustrated exemplified embodiment.

[0021] Finally, figure 10 shows the locking piece 11 which is provided with a guide groove 25

Which runs on a corresponding nb in fhe housing. Also located on the looking piece 11 Is the control bolt 12. which engages mto the control contour 10 in the displacement plate 3, and the edge 13 which cooperates with the shoulder 14 and/or the second step IS of the: looking fab in the locking position.
