Description

The present invention relates to a self-locking locking device according to the preamble of claim 1

the end WO 2010/085132 A1 and EP 2 956 605 A1 such a self-locking locking device is known. The main locking element has a pin which engages in a guide slot of a locking rod. The guide slot runs obliquely to a direction of movement of the pin when the main locking element is moved into the closed position or into the open position. Due to the inclined arrangement of the guide slot, the locking rod is moved in one direction during a closing movement and in the other direction during an opening movement. In this way, a closing or opening process is effected on the at least additional locking element, either directly or indirectly after the direction of movement of the locking rod has been deflected.

This known self-locking locking device has the disadvantage that the movement initiated during a closing or opening process in one direction requires a great deal of force. This is not desirable in an automated process. The locking device should be easy to move. In addition, the additional locking elements have to be designed differently, since the locking rod moves in different directions relative to these during a closing process or during an opening process.

Other self-locking locking devices are known in the art well known. These are designed so that the locking device z. B. when a door closes, automatically locked when a release element is activated or operated on the strike plate side. There are also multi-point lock drives from the prior art are known to z. B. a door not only via the main locking element directly connected to the locking device but also with at least one additional additional locking element at a vertical distance from the

To lock the main locking element. Such multi-point locking drives are regularly actuated via a separate locking mechanism after the actual main lock has been locked. For this reason, several lock cylinders are then required, which may also require different keys. The handling of such a known multi-point lock in connection with such a known self-locking locking device is therefore inconvenient and complex for the user.

The object of the present invention is therefore to develop a self-locking locking device of the type mentioned at the outset in such a way that multiple locking can be carried out much more easily with it in a single automatic locking process.

The object is achieved according to the invention in that the first guide device and the second guide device are each designed as a longitudinal slot with two parallel longitudinal edges.

The present invention is based on the idea of deflecting the approximately horizontal movement of a main locking element into two vertical movements in the assembled state of a locking device in order to control at least two additional locking elements independently of one another when the locking of the main locking element is triggered automatically will.

This is achieved in that two additional locking elements are driven by separate drive parts. The force is divided in the case of a closing movement and an opening movement. In addition, the two additional locking elements can be constructed identically.

According to the invention, the first drive part has a first locking rod and the second drive part has a second locking rod and when the main locking element moves in a locking direction, the first locking rod moves in a first direction different from the locking direction and the second locking rod moves in one of the latch direction and the first direction different second direction moves.

Through the first and second deflection of the movement from a locking direction into a first direction different from the locking direction and a different direction from the locking direction and the first direction, identical additional locking elements remote from the main locking element can be controlled and moved.

Another advantage of the present invention is that the locking rod has a longitudinal axis and the guide device is oriented in a main plane at an angle to the longitudinal axis.

The inclined arrangement of a guide device makes it possible to cause the extension piece connected to the main locking element not only to move horizontally but also to move vertically at the same time when the main locking element is moved between a closed position and an open position in the operating state.

Another advantage of the present invention is that the guide device has an incline, the extension piece overcoming the incline on the way of the main locking element from the closed position into the open position.

This embodiment corresponds to the embodiment described in the following description and can be implemented in a structurally favorable manner.

Alternatively, it can also be advantageous that the guide device has a gradient and the extension piece overcomes the gradient on the way of the main locking element from the closed position into the open position. This embodiment could also be structurally favorable under certain circumstances, so that the person skilled in the art is free to choose between the embodiments depending on the application.

Another advantage of the present invention is that the extension piece on a The lower edge of the main locking element is arranged. The position of the extension piece and the slope determine the path of the respective additional locking element between the closed position and the open position.

Another advantage of the present invention is that the other piece is arranged on an upper edge of the main locking element. In this case, the extension piece and the incline of the guide device also determine the path between the closed position and the open position of the respective additional locking element.

Another advantage of the present invention is that the other piece is guided out of its movement in the longitudinal slot on both of them in parallel. This ensures that the extension piece is guided firmly in both directions between a closed position and an open position.

It is also advantageous that the extension piece is a roller which has an axis of rotation perpendicular to the main plane. The friction in the guide device is significantly reduced by a roller.

Another advantage of the present invention is that the locking rod is connected to a second additional locking element via a second actuating drive bracket. This makes it possible to create a multi-point lock on the top, for example on the door, in the middle and on the underside of a door.

Finally, it is also advantageous that a locking device with a Multi-point locking drive is equipped according to the present invention.

In Fig. 1 is a schematic view from the side of an arrangement of a self-locking locking device 1 with a multi-point locking drive 2, which is in a closed position. In Fig. 2 is a schematic view from the side of an arrangement of a self-locking locking device 1 with a multi-point locking drive 2, which is in an open position. The locking device 1 is arranged, for example, in a door and is limited on one side by a faceplate 3 in which openings 7 are formed, with a main locking element 5 in a locking direction RR through an opening 7 into a closed position ( Fig. 1 ) and back to an open position ( Fig. 2 ) can be moved. In FIGS. 1 and 2 the path (the locking direction RR) of the main locking element 5 from the closed position to the open position and vice versa are each represented by an arrow.

The locking device 1 has a cylinder lock 9, via which the locking device can be triggered manually, for example to move the main locking element 5 from the closed position into the open position or vice versa from the open position into the closed position. Alternatively and not shown, the locking device 1 can also be provided with an electromagnetic door opener, which automatically triggers a closing process and / or an opening process without the cylinder lock 9 having to be actuated.

When activated, the main locking element 5, which is prestressed by a first compression spring 12, is moved through its opening 7 into the closed position and blocked in this position.

In many situations it is desirable not to close a door, window or any other component closing a wall opening with a single main locking element 5, but also to close at least one additional locking device 11 with at least one additional locking element 11.1, 11.2 use. The locking mechanisms for additional locking elements 11.1 and 11.2 can be designed as desired. A preferred and advantageous embodiment for the present invention is shown in FIGS Figures 3 and 4 shown. The respective additional locking elements 11.1, 11.2 are connected to a first locking rod 15.1 or a second locking rod 15.2 via an actuator tab 13.1, 13.2.

The first locking rod 15.1 has a first longitudinal axis L1 and a main plane H that coincides with the plane of the sheet Figure 1 coincides. The second locking rod 15.2 has a second longitudinal axis L2 and a main plane H that coincides with the plane of the sheet Figure 1 coincides. The first locking rod 15.1 has a first free end 15.3 into which the actuator lug 13.1 of a first additional bolt locking device 11 engages. The second locking rod 15.2 has a second free end 15.4, in which the second actuator bracket in the present embodiment 13.2 of a second additional bolt locking device 11 engages. The locking rod and actuator bracket do not interlock directly, but are coupled by a connecting rod element (can be up to 40cm long).

The respective actuator brackets can also be connected to more than a single additional locking element 11.1, 11.2. The first locking rod 15.1 and the second locking rod 15.2 are shown in FIG Fig. 1 and in Fig. 2 movable up and down. The first locking rod 15.1 moves in a first direction ER and the second locking rod 15.2 moves in a second direction ZR, the two directions ER and ZR being opposite to each other in the present embodiment. In an installed state, such a movement corresponds to a movement approximately in the vertical direction (upwards or downwards). In the embodiment shown in the figures, the first locking rod 15.1 moves upwards (ER) during a closing process and downwards (ZR) during an opening process, while the first locking rod 15.2 moves synchronously downwards (ZR) during a closing process and downwards during an opening process synchronously moved up (ER).

The main locking element 5 moves behind the main plane transversely to the first and second locking rods 15.1 and 15.2, respectively. In the installed state, the main locking element 5 performs an approximately horizontal locking movement in a locking direction RR, which in the figures means a movement to the left during a closing process and a movement to the right during an opening process. On the side of the main locking element 5 facing the viewer, a drive element 17 is provided as Formed extension piece or pin.

The locking device 1 comprises a drive device for each additional bolt locking device 11. In the present embodiment, the drive device comprises a first drive part 17.1 with the first locking rod 15.1 and a second drive part 17.2 with the second locking rod 17.2.

In Fig. 1a is that in the locking device 1 in Fig. 1 integrated, first drive part 17.1 shown separately, that is, in the closed position. In Figure 1b is that in the locking device 1 in Fig. 1 integrated, second drive part 17.2 shown separately, also in the closed position. In Fig. 2a is that in the locking device 1 in Fig. 2 integrated, first drive part 17.1 shown separately, that is, in the open position. In Figure 2b is that in the locking device 1 in Fig. 2 integrated, second drive part 17.2 shown separately, so also in the open position.

The first drive part 17.1 comprises the first locking rod 15.1 with the main plane H and the second drive part 17.2 comprises the second locking rod 15.2 with the main plane H. The two drive parts are in FIGS. 1 and 2 arranged one behind the other perpendicular to the plane of the sheet or main plane H and can slide on one another during operation. In the embodiment shown, the two drive parts 17.1 and 17.2 are essentially identical in shape and are rotated about a horizontal line and arranged offset from one another in a vertical line, so that the two locking rods 15.1 and 15.2 can at least partially overlap when installed.

The drive element 17, connected to the bolt 5, can also be designed as a roller with an axis of rotation perpendicular to the main plane H. The drive element 17 engages in a first guide device 19.1 of the first locking rod 15.1 and in a second guide device 19.2 of the second locking rod 15.2. In the present embodiment, the first and the second guide device 19.1 and 19.2 are each a recess and in particular each a longitudinal slot which runs in the main plane H at an angle to the first and second longitudinal axes L1, L2. The angle between the first guide device 19.1 to the first longitudinal axis L1 and the second guide device 19.2 to the second longitudinal axis L2 does not have to be fixed for the present invention, but is in the range of approx. 30 ° to approx. 50 °. The angle of the first guide device 19.1 in relation to the first longitudinal axis L1 can also be different from the angle of the second guide device 19.2 in relation to the second longitudinal axis L2. In the embodiment shown in the figures, the angle is the same.

The alignment of the first guide device 19.1 and the second guide device 19.2 in relation to their longitudinal axes L1 and L2, however, is mirror-inverted. In the embodiment shown, the slope of the first guide device 19.1 for the drive element 17 is positive during a closing movement (main locking element 5 to the left) and negative during an opening movement (main locking element 5 to the right). The slope of the second guide device 19.2 is negative for the drive element 17 during a closing movement (main locking element 5 to the left) and positive during an opening movement (main locking element 5 to the right). The first guide device 19.1 embodied as a longitudinal slot has two parallel first longitudinal edges and the second guide device 19.2 embodied as a longitudinal slot has two parallel second longitudinal edges. The drive element 17 is guided on the first longitudinal edges and the second longitudinal edges of the longitudinal slots 19.1 and 19.2. In other embodiments, the first guide device 19.1 and the second guide device 19.2 can also be designed differently and even quite differently. It is also possible for the first and second guide devices 19.1 and 19.2 to be designed differently and to enclose different angles to their longitudinal axes.

In the illustrated embodiment, the first guide device 19.1 for the drive element 17 on the way from the illustrated closed position to an open position (arrow direction) forms a positive slope (the drive element is retracted, moved downwards), which the drive element 17 overcomes on this path and forms the second guide device 19.2 for the drive element 17 on the way from the illustrated closed position to an open position (arrow direction) a negative slope (the drive element is retracted, moved upwards), which the drive element 17 overcomes on this path. On the way from the closed position to the open position, a relative movement takes place between the drive element 17 and the respective first guide device 19.1 and second guide device 19.2 due to predetermined guide paths. Overcoming the positive and negative slope of the first and second guide device 19.1, 19.2 takes place due to the horizontal movement (locking direction RR) of the main locking element 5, each of which forces the first locking rod 15.1 to evade in the vertical direction downwards (arrow direction) and the second locking rod 15.2 forces to evade in the vertical direction upwards (arrow direction). The evasion is made possible by the guide device 19.1 or 19.2.

In Fig. 1a the first drive part 17.1 with the longitudinal axis L1 is shown in detail. In Figure 1b is the second drive part 17.2 with the longitudinal axis L2 in relation to the first drive part 17.1 laterally shifted to the left but in the position in which the two drive parts in Fig. 1 lie on top of each other and slide along each other. The first locking rod 15.1 has a first free end 15.3 which is designed to establish a mechanical connection with a first additional bolt locking device 11. The first free end 15.3 is much narrower in the main plane H than the first locking rod 15.1. The first locking rod 15.1 has a widening of about twice as much. In this area, the first guide device 19.1 is designed as a longitudinal slot in the first locking rod 15.1 in the manner already described. The guide device 19.1 is arranged obliquely in relation to the first longitudinal axis L1 and extends in the illustrated embodiment from the bottom left to the top right. The second locking rod 15.2 has a second free end 15.4 which is designed to establish a mechanical connection with a second additional bolt locking device 11. The second free end 15.4 is also made much narrower in the main plane H than the second locking rod 15.2. The second locking rod 15.2 has a widening of about twice as much. In this area, the second guide device 19.2 is in the second locking rod 15.2 as a longitudinal slot in the already described manner. The second guide device 19.2 is arranged obliquely with respect to the second longitudinal axis L2 and extends in the illustrated embodiment from the top left to the bottom right.

In Figures 2a and 2b the first drive part 17.1 and the second drive part 17.2 are shown in relation to one another as in FIG Figures 1a and 1b , but in the open position, i.e. shifted in the longitudinal direction, so that the two drive parts overlap by a larger amount.

In Fig. 3 the two additional bolt locking devices 11 are shown open. Since both additional bolt locking devices 11 are structurally identical and only arranged in mirror image, only the upper additional bolt locking device 11 is shown in FIG Fig. 3 described in more detail. The upper additional bolt locking device 11 has a first additional bolt locking element 11.1. This is in Fig. 3 , as well as the main locking element 5, in the closed position. The first additional bolt locking element 11.1 is connected to an additional bolt drive part 25 via an additional bolt drive element 14, which is connected to the additional bolt locking element 11.1, and a first additional bolt guide device 16.1. The actuator lugs 13.1 and 15.3 do not interlock directly, but are coupled by a connecting rod element (can be up to 40cm long).

The additional bolt drive part 25 in turn has at a free end the actuator lug 13.1 for mechanical connection to the first free end 15.3 of the drive part 15.1. The first additional bolt guide device 16.1 is also a longitudinal slot which is aligned in accordance with the first guide device 19.1. In the present embodiment, the angle to a vertical is also equal to the corresponding angle of the first guide device 19.1. However, this does not have to be the case in other embodiments. The angle can be adapted to the distance of the additional bolt closing element 11.1. So that the whole thing works, the additional bolt drive element 14 engages in the first additional bolt guide device 16.1 at the top and in a horizontal second additional bolt guide device 16.2 at the bottom, which is formed in the housing base.

In this way, the additional bolt part 25 moves downwards, connected to 15.3 and driven by means of a connecting element with drive part 15.1 in the Fig. 4 shown open position

The additional bolt drive part 25 must in the case of a horizontal opening movement in the in Fig. 4 Dodge shown open position down and moves together with the first drive part 15.1 down until the open position in Fig. 4 is reached. The additional bolt drive element 14 is then in Fig. 4 in the vicinity of the other upper end of the first additional bolt guide device 16.1. With a horizontal closing movement from the open position in Fig. 4 in the closed position in Fig. 3 the processes are reversed.

In other embodiments, the closing movement or the opening movement need not necessarily run horizontally. The respective closing elements can have different directions of movement (eg larger or smaller than 90 ° to the vertical) and also different directions of movement with respect to one another. But the principle always remains the same.
