Description

The present invention relates to a self-locking device having a trigger member and a main latch member automatically moves to a closed position at Schließblechseitiger activation of the trigger element, wherein the main latch member comprises a drive element for a multi-lock actuator, the at least one auxiliary bolt locking device with at least one Additional locking element at a distance from the main locking element drives, wherein the drive element cooperates with a drive device for at least one additional locking element.

The present invention also relates to an auxiliary latch device for such a self-locking latch.

Out 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 extends obliquely to a direction of movement of the pin when the main locking element is moved to the closed position or in the open position. Due to the oblique arrangement of the guide slot, the locking rod is moved in a closing movement in one direction and an opening movement in the other direction. In this way, a closing or opening operation is effected on the at least additional locking element, either directly or indirectly after deflection of the direction of movement of the locking rod.

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

Other self-locking locks are well known in the art. These are constructed so that the closing device z. B. when a door closes, automatically locked when a trigger element is activated or actuated closing plate side. There are also multi-lock actuators known from the prior art, for. B. to lock a door not only on the directly related to the locking device main locking element but also with at least one additional additional locking element at a vertical distance to the main locking element. Such multiple-locking actuators are regularly actuated via a separate locking mechanism after the actual main lock has been locked. For this reason, then several lock cylinders are required, which may also require different keys required. The handling of such a known multiple locking in connection with such a known self-locking locking device is thus uncomfortable and expensive for the user.

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

The object is achieved in that the drive means comprises a first drive part and a second drive part, wherein the drive element cooperates with the first drive part for a first additional locking element and with the second drive part for a second additional locking element and a movement of the first drive part and of the second drive part is synchronized with a movement of the main latch member.

The present invention is based on the idea of deflecting in the mounted state of a closure device in approximately horizontal movement of a main locking element in two vertical movements, so as to control at least two additional additional locking elements independently of each other when the lock of the main locking element is automatically triggered ,

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

Another advantage is that the first drive part and a first locking bar the second drive part has a second lock bar, and when the main lock element moves in a lock direction, the first lock bar is different in a first direction from the lock direction and the second lock bar is second different from the lock direction and the first direction Direction moves.

By the first and second deflection of the movement from a bolt direction in a direction different to the bolt direction and a direction to the bolt direction and the first direction different direction remote from the main latch element lying identical additional locking elements can be controlled and moved.

Another advantage of the present invention is that the locking bar has a longitudinal axis and the guide device is aligned in a main plane obliquely to the longitudinal axis.

Due to the oblique arrangement of a guide device, it is possible to cause connected to the main latch element lug not only to a horizontal movement but at the same time to a vertical movement when the main latch member is moved in the operating state between a closed position and an open position.

Another advantage of the present invention is that the guide means has a pitch, the nosepiece being the pitch on the path of the main latch member from the closed position overcomes in the open position.

This embodiment corresponds to the embodiment described in the following description and can be realized constructively low.

Alternatively, it may also be advantageous that the guide means has a slope and the extension piece overcomes the slope on the way of the main locking element from the closed position to the open position. This embodiment could be structurally favorable under certain circumstances, so that the expert is free to choose between the embodiments depending on the application.

A further advantage of the present invention is that the extension piece is arranged on a lower edge of the main locking element. The position of the extension 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 located at an upper edge of the main latch member. In this case also determine the extension and the slope of the guide means 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 in parallel from its movement in the longitudinal slot at both. As a result, a fixed guide in both directions of the extension piece between a closed position and ensures an open position.

Likewise, it is advantageous that the extension piece is a roller having a rotation axis perpendicular to the main plane. By a roller, the friction in the guide device is significantly reduced.

Another advantage of the present invention is that the locking bar is connected via a second actuator lug with a second additional locking element. This makes it possible to produce a multi-point lock at the top, for example, at the door, in the middle and at the bottom of a door.

Finally, it is also advantageous that a locking device is equipped with a multi-lock actuator according to the present invention.

In Fig. 1 is a schematic view from the side of an arrangement of a self-locking closure device 1 shown with a multi-lock actuator 2, which is in a closed position. In Fig. 2 is a schematic view from the side of an arrangement of a self-locking closure device 1 shown with a multi-lock actuator 2, which is in an open position. The locking device 1 is arranged, for example, in a door and is bounded on one side by a face-plate 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. Fig. 1 ) and back to an open position ( Fig. 2 ) can be moved. In Fig. 1 and Fig. 2 are the way (the latch direction RR) of the main locking element 5 from the closed position to the open position and vice versa 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 to the open position or vice versa from the open position to the closed position. Alternatively and not shown, the closing device 1 may also be provided with an electromagnetic door opener which automatically triggers a closing operation and / or an opening operation without the cylinder lock 9 having to be actuated.

By activation, the biased by a first compression spring 12 main-locking element 5 is moved through its opening 7 in the closed position and blocked in this.

In many situations it is desirable not to close a door, a window or any other component closing a wall opening with a single main locking element 5, but additionally at least one additional auxiliary 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 configured as desired. A preferred and for the present invention favorable embodiment is in the FIGS. 3 and 4 shown. The respective additional locking elements 11.1, 11.2 are connected via an actuator drive lug 13.1, 13.2 with a first locking bar 15.1 or second locking bar 15.2.

The first locking bar 15. 1 has a first longitudinal axis L 1 and a main plane H corresponding to the plane of the page FIG. 1 coincides. The second locking bar 15.2 has a second longitudinal axis L2 and a main plane H, with the plane of the plane FIG. 1 coincides. The first locking rod 15.1 has a first free end 15.3, in which engages the actuator tab 13.1 of a first auxiliary bolt locking device 11. The second locking bar 15.2 has a second free end 15.4, in which engages in the present embodiment, the second actuator tab 13.2 of a second auxiliary bolt locking device 11. Locking rod and actuator tab do not mesh directly with each other but are coupled by a connecting rod element (can be up to 40cm long).

The respective actuator tabs can also be connected to more than one single additional locking element 11.1, 11.2. The first locking bar 15.1 and the second locking bar 15.2 are in Fig. 1 and in Fig. 2 movable up and down. In this case, the first locking bar 15.1 moves in a first direction ER and the second locking bar 15.2 moves in a second direction ZR, the two directions ER and ZR being opposite to one another in the present embodiment. In a built-in state, such a movement corresponds to a movement approximately in the vertical direction (upwards or downwards). Moved in the embodiment shown in the figures up or down). In the embodiment shown in the figures, the first locking bar 15.1 moves upwards (ER) during a closing operation and downwards (ZR) during an opening operation, while the first locking bar 15.2 moves synchronously downwards (ZR) during a closing operation and during an opening operation synchronously moved up (ER).

The main locking element 5 moves behind the main plane transversely to the first and second locking bar 15.1 and 15.2. When installed, the main locking element 5 performs an approximately horizontal locking movement in a locking direction RR, which means a movement to the left in the figures during a closing operation and a movement to the right in an opening operation. On the side facing the viewer of the main locking element 5, a drive element 17 is formed as a lug or pin.

The closing device 1 comprises a drive device for in each case one auxiliary bolt closing device 11. In the present embodiment, the drive device comprises a first drive part 17.1 with the first locking bar 15.1 and a second drive part 17.2 with the second locking bar 17.2.

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

The first drive part 17.1 comprises the first locking bar 15.1 with the main plane H and the second drive part 17.2 comprises the second locking bar 15.2 with the main plane H. The two drive parts are in Fig. 1 and Fig. 2 arranged perpendicular to the plane of the page or main plane H one behind the other and can slide on each other during operation. In the illustrated embodiment, the two drive parts 17.1 and 17.2 are substantially identical in shape and rotated about a horizontal and arranged mutually displaced in a vertical, so that the two locking rods 15.1 and 15.2 can overlap in the installed state at least partially.

The drive element 17, connected to the latch 5, can also be designed as a roller with a rotation axis 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 means 19.1 and 19.2 are each a recess and in particular in each case a longitudinal slot extending in the main plane H obliquely to the first and second longitudinal axis L1, L2. The angle between the first guide means 19.1 to the first longitudinal axis L1 and the second guide means 19.2 to the second longitudinal axis L2 need not be defined for the present invention, but is in the range of about 30 ° to about 50 °. The angle of the first guide device 19.1 with respect to the first longitudinal axis L1 may also be different than the angle of the second guide means 19.2 with respect to the second longitudinal axis L2. In the embodiment shown in the figures, the angle is the same.

The orientation of the first guide means 19.1 and the second guide means 19.2 with respect to their longitudinal axes L1 and L2, however, is mirror-inverted. In the illustrated embodiment, the pitch of the first guide means 19.1 for the drive member 17 in a closing movement (main latch member 5 to the left) is positive and negative in an opening movement (main latch member 5 to the right). By contrast, the pitch 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 designed as a longitudinal slot has two parallel first longitudinal edges and the second guide device 19.2 designed as a longitudinal slot has two parallel second longitudinal edges. The drive element 17 is guided in each case at 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 may also be designed differently and even completely differently. It is also possible that the first and second guide means 19.1 and 19.2 are uneven and include different angles to their longitudinal axes.

In the illustrated embodiment, the first guide means 19.1 for the Drive element 17 on the way from the illustrated closed position to an open position (arrow) a positive slope (the drive member is retracted, moved down), which overcomes the drive member 17 in this way and forms the second guide means 19.2 for the drive member 17 on the way out the closed position shown in an open position (arrow) a negative slope (the drive element is retracted, moved upward), which overcomes the drive member 17 in this way. On the way out of the closed position into the open position, due to predetermined guide paths, a relative movement takes place between the drive element 17 and respectively the first guide device 19.1 and the second guide device 19.2. Overcoming the positive and negative slope of the first and second guide means 19.1, 19.2 is due to the horizontal movement (latch direction RR) of the main latch member 5, which forces the first locking bar 15.1, in the vertical direction to move downwards (arrow) and the second locking rod 15.2 forces to dodge in the vertical direction upwards (arrow direction). Dodge is made possible by the guide device 19.1 or 19.2.

In Fig. 1a the first drive part 17.1 is shown in detail with the longitudinal axis L1. In Fig. 1b is the second drive member 17.2 with the longitudinal axis L2 with respect to the first drive part 17.1 laterally moved to the left but in the position in which the two drive parts in Fig. 1 lie over each other and can slide along each other. The first locking bar 15. 1 has a first free end 15. 3, which is designed to produce a mechanical connection with a first auxiliary bolt closing device 11. The first free end 15.3 is much narrower in the main plane H. designed as the first locking bar 15.1. The first locking bar 15.1 has a widening by about twice. In this area, the first guide device 19.1 is formed as a longitudinal slot in the manner already described in the first locking bar 15.1. The guide device 19.1 is arranged obliquely with respect to the first longitudinal axis L1 and extends in the illustrated embodiment from bottom left to top right. The second locking bar 15.2 has a second free end 15.4 which is designed to produce a mechanical connection with a second auxiliary bolt closing device 11. The second free end 15.4 is also much narrower in the main plane H than the second locking bar 15.2. The second locking bar 15.2 has a widening by about twice. In this area, the second guide device 19.2 is formed as a longitudinal slot in the manner already described in the second locking bar 15.2. The second guide means 19.2 is arranged obliquely with respect to the second longitudinal axis L2 and extends in the illustrated embodiment from top left to bottom right.

In Fig. 2a and Fig. 2b For example, the first drive part 17.1 and the second drive part 17.2 are illustrated with respect to each other as in FIG Fig. 1a and Fig. 1b , but in the open position, that is shifted in the longitudinal direction, so that overlap both drive parts to a greater extent.

In Fig. 3 the two auxiliary bolt locking devices 11 are shown open. Since both additional bolt locking devices 11 are identical and only mirror-inverted, only the upper auxiliary bolt locking device 11 is in Fig. 3 closer described. The upper additional bolt closing device 11 has a first additional bolt closing element 11.1. This is located in Fig. 3 , as well as the main locking element 5, in the closed position. The first auxiliary bolt closing element 11.1 is connected via an additional bolt drive element 14, which is connected to the auxiliary bolt closing element 11.1, and a first auxiliary bolt guide device 16.1 with an additional bolt drive part 25. Actuator tabs 13.1 and 15.3 do not engage directly with each other, 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. Also, the first auxiliary bar guide means 16.1 is a longitudinal slot, which is aligned according to the first guide means 19.1. In the present embodiment, the angle to a vertical is equal to the corresponding angle of the first guide means 19.1. But that 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. In order for the whole thing to work, the auxiliary bar drive element 14 engages the top of the first auxiliary bar guide device 16.1 and the bottom of a horizontal second auxiliary bar guide device 16.2, which is formed in the housing bottom.

In this way, the auxiliary latch member 25 moves down, connected to 15.3 and driven by means of a connecting element with drive part 15.1 in the in Fig. 4 shown opening position

The additional bolt drive part 25 must be in a horizontal opening movement in the in Fig. 4 shown open position dodge down and moves together with the first drive part 15.1 down to the open position in Fig. 4 is reached. The auxiliary bar drive element 14 is then in Fig. 4 near the other upper end of the first auxiliary bar guide 16.1. In 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 be horizontal. The respective closing elements may have other (eg greater or less than 90 ° to the vertical) and also different directions of movement to each other. The principle always remains the same.
