LOCK WITH BOLT BAR

Description

[0001] The invention relates to a locking device with a locking bar according to the features of the preamble of claim 1 and a method for adjusting a locking device with a locking bar according to the features of the preamble of claim 14.

[0002] In practice, locks are used to securely lock a door. To ensure increased security, locks can have additional locking points. These additional locking points are controlled from the central lock case via locking bars, as described, for example, in DE 101 62 793 A1, US 2019 / 277064 A1, or EP 3 045 624 A1.

[0003] The present invention is based on the object of providing an improved and more universally applicable locking device with a locking bar and a method for adjusting such a locking device. This object is achieved according to the invention by a locking device with a locking bar according to the features of claim 1.

[0004] According to the invention, a locking device for a pivotably mounted leaf of a door or window, in particular a deadbolt lock, is proposed, wherein the locking device has a lock that can be mounted in or resting on the wing, and the lock has a lock housing and a lock mechanism arranged therein, and the lock has a locking element that can be actuated by the locking mechanism, and the locking element can be actuated by a slide plate of the lock mechanism between a pre-closed locking position and an unlocking position retracted into the lock housing, and wherein the locking device further has at least one locking bar that can be mounted in or resting on the wing and actuated by the lock mechanism, and the locking bar can be actuated by the slide plate of the lock mechanism along an actuation path between a pre-closed locking position and an unlocking position retracted into or onto the wing.

[0005] What is important here is that a gear is formed between the slide plate and the locking rod to translate a movement path of the slide plate into the actuation path of the locking rod, and that the length of the actuation path of the locking rod is adjustable by the gear.

[0006] Furthermore, the object is achieved by a method for adjusting a locking device with a locking bar according to the features of claim 14.

[0007] According to the invention, a method for adjusting a locking device for a pivotably mounted leaf of a door or window, in particular a drive bolt lock, is proposed, wherein the locking device has a lock that can be mounted in or resting on the leaf, and the lock has a lock housing and a lock mechanism arranged therein, and the lock has a locking element that can be actuated by the lock mechanism, and the locking element can be actuated by a slide plate of the lock mechanism between a pre-locked locking position and an unlocking position retracted into the lock housing, and wherein the locking device further comprises at least one locking bar which can be mounted in or resting on the wing and actuated by the lock mechanism, and the locking bar can be actuated by the slide plate of the lock mechanism along an actuating path between a pre-closed locking position and an unlocking position retracted into or onto the wing, wherein the method comprises the following steps: i) mounting the lock in or on a pivotably mounted wing of a door or window; ii) mounting the locking bar in or on the pivotably mounted wing of the door or window; iii) connecting the locking bar to the slide plate via a gear for translating a movement path of the slide plate into the actuating path of the locking bar.

[0008] It is essential that the gear is designed to translate a movement path of the slide plate into the actuation path of the locking rod, and that in step iii) the transmission ratio of the movement path of the slide plate to the actuation path of the locking rod can be selected by connecting the locking rod to the slide plate via the gear.

[0009] An advantage of the device and method according to the invention is that one locking device can be used for different actuation paths of the locking bar without using a different lock mechanism. The locking bar, also called a driving bolt bar, can be used to actuate various additional components, for example a lock or a switch lock, etc. Such additional components have different actuation strokes depending on the manufacturer. By adjusting the gear ratio, the stroke of the locking bar can be adjusted, in particular by adapting it to a specific accessory. This makes it possible to use a wide variety of additional components on a driving bolt lock. If the locking bar is used for locking, the stroke of the locking bar and thus the engagement depth in a receptacle on the door frame can be adjusted by changing the gear ratio.

[0010] One advantage is that the stroke of the bolt remains unchanged even when the gear is changed.

[0011] The gear mechanism can be provided with at least two fixed gear ratios for converting the travel of the slide plate into the actuation travel of the locking rod. Here, the gear ratio refers to the magnitude or ratio of the mechanical movement transmission.

[0012] It can be provided that the transmission is designed to be switchable between at least two fixed gear ratios.

[0013] It can be provided that by the connection in step iii) a fixed transmission ratio for translating the movement path of the slide plate into the actuation path of the locking rod is selected from two or more transmission ratios for translating the movement path of the slide plate into the actuation path of the locking rod.

[0014] It can be provided that a first gear ratio enables a locking bar actuation travel of 12 mm, and that a second gear ratio enables a locking bar actuation travel of 20 mm. These dimensions are to be understood as examples and can be varied in practice. For example, the first stroke can be in the range of 8 mm to 15 mm, and the second stroke can be in the range of 16 mm to 25 mm.

[0015] The slide plate can be provided with a fixed travel path, preferably a travel path of a fixed length. A fixed travel path here means that, for example, to actuate the locking bar from the locked position to the unlocked position and back, the slide plate is always moved by the same length of travel, regardless of the actuation path of the locking bar. The locking element can be provided with a fixed stroke path of a fixed length, preferably a fixed stroke path of a fixed length, even when changing the gear.

[0016] It can be provided that the path of the locking bar between the pre-locked locking position and the retracted unlocking position corresponds to the actuation path of the locking bar.

[0017] It can be provided that the travel of the slide plate for actuating the locking element between the pre-closed locking position and the retracted unlocking position corresponds to the travel of the slide plate. The travel of the slide plate for actuating the locking element also corresponds to the travel of the locking rod, regardless of the length of the locking rod's travel.

[0018] It can be provided that the transmission is designed as one or more gears or one or more friction wheels.

[0019] It can be provided that the transmission is designed as a crank transmission.

[0020] It can be provided that the gear is designed as one or more levers.

[0022] The lever can be provided with its first lever arm to interact with the slide plate. The lever can be provided with its second lever arm to interact with the locking bar.

[0023] It can be provided that the lever is rotatably mounted in the lock housing, in particular via a pin arranged in the lock housing or a rotation axis arranged in the lock housing.

[0024] It can be provided that, in order to translate the movement path of the slide plate into the actuation path of the locking rod, preferably in step iii), one or more transmission elements are formed on the slide plate and / or on the lever and / or on the locking rod, preferably for transmitting the movement of the slide plate via the gear to the locking rod.

[0025] It can be provided that one or more transmission elements are formed on the slide plate and / or on the crank mechanism and / or on the locking bar in order to translate the movement path of the slide plate into the actuation path of the locking bar.

[0026] It can be provided that, in order to transmit the movement of the slide plate to the locking bar, a slide transmission element is formed which transmits the movement of the slide plate to the lever and / or a locking bar transmission element is formed which transmits the movement of the lever to the locking bar.

[0027] It can be provided that two or more positions are provided on the slide plate and / or on the lever, preferably on the first lever arm, for attaching the slide transmission element. The different positions allow the transmission point of the slide plate movement to the lever to be selected, resulting in a different translation of the movement path to the actuation path due to the two-armed lever.

[0028] It can be provided that the two or more positions on the slide plate or on the lever for the slide transmission element differ in such a way that they form different lengths of the lever arm, preferably of the first lever arm, when transmitting the movement of the slide plate to the lever.

[0029] It can be provided that two or more positions are formed on the locking bar or on the lever, preferably on the second lever arm, for attaching the locking bar transmission element. The different positions allow the transmission point of the lever's movement to the locking bar to be selected, resulting in a different translation of the movement path to the actuation path due to the two-armed lever.

[0030] It can be provided that the two or more positions on the lever or on the locking bar for the locking bar transmission element differ in such a way that they form different lengths of the lever arm, preferably of the second lever arm, when transmitting the movement of the lever to the locking bar.

[0031] It can be provided that the slide transmission element is arranged on the slide plate or on the lever, preferably inserted and / or screwed and / or guided in a groove or an elongated hole.

[0032] It can be provided that the locking bar transmission element is arranged on the lever or on the locking bar, preferably inserted and / or screwed and / or guided in a groove or an elongated hole.

[0033] It can be provided that one or more access openings are formed in the lock housing for fastening the slider transmission element and / or the locking bar transmission element.

[0034] It can be provided that the slide transmission element and / or the locking bar transmission element are designed as a pin or as a shaft or as a projection or as an adjustable stop.

[0035] The adjustable stop can be provided with a rotatable mounting on the slide plate, the lever, or the locking bar. By rotating it, the various positions for transmitting the lever's movement to the locking bar can be adjusted.

[0036] Further embodiments of the invention are illustrated in the figures and described below. The figures show a possible embodiment of the invention by way of example. This embodiment serves to illustrate a possible implementation of the invention and is not intended to be limiting. They show: Fig. 1: A schematic representation of a locking device 1 according to the invention in a door 2; Fig. 2: Locking device 1 according to the invention in a locking position; Fig. 3: Locking device 1 according to the invention in a first unlocking position with a small actuating travel x 1 ; Fig. 4: Locking device 1 according to the invention in a first unlocking position with a large actuating travel x 2 .

[0037] Fig. 1 shows a locking device 1 according to the invention in a door 2. The door 2 is arranged in a door frame 3 on hinges 4. The locking device 1 has a lock 10 mounted in the door 2, comprising a locking element 13, which is arranged in a lock housing 11, and a locking bar 20.

[0038] As in the Fig. 2 to 4As shown, a lock mechanism 12 with a slide plate 14 is arranged in the lock housing 11. By actuating the locking device 1, for example by a push button (not shown in the figures), the slide plate 14 is displaced by a movement path s of the slide plate 14.

[0039] The slide plate 14 actuates both the locking element 13 and the locking rod 20 between a pre-closed locking position, as in Fig. 2 shown, and one unlocking position retracted into the wing, as shown in the Fig. 3 or 4 The slide plate 14 acts in the embodiment of the Fig. 2 to 4 to actuate the locking element 13 via a slotted hole onto a pin of the locking element 13. The slide plate 14 acts in the embodiment of the Fig. 2 to 4 via a gear 30 onto the locking bar 20 to actuate the locking bar 20.

[0040] In the embodiment of the Fig. 2 to 4 the gear 30 is designed as a two-armed lever 31, which is arranged in a stationary and rotatable manner in the lock housing 11 via a bearing 32 of the lever 31.

[0041] The lever 31 has a first lever arm 33, which interacts with the slide plate 14 via a slide transmission element 35. The lever 31 further has a second lever arm 34, which interacts with the locking bar 20 via a locking bar transmission element 36.

[0042] In the exemplary embodiment, the gearbox has Fig. 2 to 4 two fixed transmission ratios for translating the movement path s of the slide plate 14 into the actuation path x of the locking rod 20. For this purpose, the slide plate 14 in the embodiment of the Fig. 2 to 4Two possible fastening positions 37 of the slide transmission element 35 are formed in the slide plate 14. The slide transmission element 35 can be arranged in these two possible fastening positions 37 of the slide transmission element 35 in order to form one of the two fixed transmission ratios for translating the movement path s of the slide plate 14 into the actuation path x of the locking rod 20.

[0043] In the embodiment of the Fig. 2 to 4 The slide transmission element 35 is designed as a pin. The lock housing 11 has an opening 15 through which the slide transmission element 35 can be arranged in one of the two possible fastening positions 37 of the slide transmission element 35 in the slide plate 14. The locking bar transmission element 36 is arranged as a pin fixed in the locking bar 20 and interacts with the lever 31 via an elongated hole in the second lever arm 34.

[0044] Fig. 2 shows the locking device 1 according to the invention with the locking element 13 and the locking bar 20 each in the pre-closed locking position. Figs. 3 and 4 show the locking device 1 according to the invention with the locking element 13 and the locking bar 20 each in a retracted unlocking position.

[0045] Depending on the arrangement of the slide transmission element 35 in one of the two possible fastening positions 37 of the slide transmission element 35, the constant movement path s of the slide plate 14 causes a different actuation path x of the locking rod 30, as shown in the Figs. 3 and 4 It should be noted that the movement path s of the slide plate 14 is Fig. 3 as well as in Fig. 4 the same distance, and the locking rod 20 is actuated by the gear 30 by two different actuating paths x 1 and x 2.

[0046] In Fig. 3The slide transmission element 35 is arranged in the right-hand mounting position 37 of the slide transmission element 35. As a result, the movement path s of the slide plate 14 is translated into the first actuation path x 1 of the locking rod 20. This represents the first transmission ratio for translating the movement path s of the slide plate 14 into the actuation path x 1 of the locking rod 20.

[0047] In Fig. 4 The slide transmission element 35 is arranged in the left fastening position 37 of the slide transmission element 35. This translates the movement path s of the slide plate 14 into the actuation path x 2 of the locking rod 20.

[0048] The different actuation paths x 1 and x 2 are generated by the different transmission points through the slide transmission element 35 from the slide plate 14 to the lever 33.

[0049] The return of the locking rod from the unlocking position to the locking position can be effected, for example, by moving the slide plate 14 and applying additional force to the lever 31 or the locking rod 20, for example by a spring, or, for example, by guiding the slide transmission element 35 in an elongated hole of the lever 31 and by actuating the slide plate 14.
