Description

Self-locking device with multipoint locking drive

Technical Field

The invention relates to a self-locking device with a trigger element and a main (latch) latch element, which automatically moves into a closed position when the activation of the trigger element is located on the side of the closing plate, wherein the main latch element comprises a drive element for a multipoint lock drive, which drives at least one additional latch device with at least one additional latch element at a spatial distance from the main latch element, wherein the drive element interacts with the drive device of the at least one additional latch element.

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

Background

Such self-locking devices are known from EP 2956605 a 1. The primary latching element has a pin which engages into a guide slot (slit) of the locking lever. The guide slot runs obliquely with respect to the direction of movement of the pin when the primary latch element is moved into the closed position or into the open position. Due to the oblique arrangement of the guide slits, the locking lever moves in one direction during the closing movement and in the other direction during the opening movement. In this way, after reversing the direction of movement of the locking bar, the closing or opening process is started directly or indirectly on the at least [ one ] additional latching element.

A disadvantage of this known self-locking device is that the movement starting in one direction during the closing process or the opening process requires a great force. This is undesirable in automated processes. The locking device should operate smoothly. Furthermore, the additional latching element must have a different design, since the locking lever moves in different directions relative to the latter during the closing process or during the opening process, respectively.

Other self-locking devices are generally known from the prior art. They are configured such that, for example, while the door is closed, the locking device automatically locks when the trigger element is activated or operated on the closure panel side. From the prior art there are also known, for example, multipoint locking drives which can lock a door not only via a main latching element in direct contact with the locking device, but also by means of at least one further additional latching element at a vertical distance from the main latching element. Such multi-point lock actuators typically operate via a separate locking mechanism after the actual master lock is locked. Therefore, several lock cylinders are required, which may also require various keys. Thus, handling such known multipoint locking in combination with such known self-locking devices is inconvenient and complicated for the user.

Disclosure of Invention

It is therefore an object of the present invention to further develop a self-locking device of the initially mentioned kind such that it can be used more easily in a single automatic locking process for performing a multipoint locking operation.

According to the invention, this object is achieved in that the drive device comprises a first drive part and a second drive part, wherein the drive element interacts with the first drive part for the first additional latch element and with the second drive part for the second additional latch element, and the movement of the first drive part and the second drive part is synchronized with the movement of the main latch element.

The invention is based on the idea of diverting a substantially horizontal movement of the main latching element into two vertical movements in the mounted state of the locking device, so that at least two further additional latching elements are controlled independently of one another when the main latching element is automatically triggered.

This is very advantageous due to the fact that the two additional latching elements are driven by separate drive members. The forces are separated during the closing movement and during the opening movement. Furthermore, the two additional latching elements can be identical in terms of structural design.

Another advantage is that the first drive member includes a first locking bar and the second drive member includes a second locking bar, and when the primary latching element moves in the latching direction, the first locking bar moves in a first direction different from the latching direction and the second locking bar moves in a direction different from the latching direction.

The additional latching element, which is located on the structure remote from the main latching element, can be actuated and moved via a first and a second steering of the movement from the latching direction to a first direction different from the latching direction and a direction different from the latching direction and the first direction.

Another advantage of the present invention is that the locking bar has a longitudinal axis and the guide means is aligned in a principal plane inclined with respect to the longitudinal axis.

The inclined arrangement of the guide means enables not only a horizontal movement, but also a vertical movement, to be caused by an accessory connected to the primary latching element when the primary latching element is moved between the closed position and the open position in the operating state.

Another advantage of the present invention is that the guide has a ramp surface that is overcome by the appendage when the primary latch element is moved from the closed position into the open position.

This embodiment corresponds to the embodiment described in the following description and is easy to implement in structure.

Alternatively, it is also advantageous for the guide means to comprise a gradient, and for the accessory to overcome the gradient when the primary latching element is moved from the closed position into the open position. In some cases, this embodiment is also convenient in construction, so that an expert can freely choose between embodiments depending on the application.

Another advantage of the present invention is that the attachment is disposed on the lower edge of the primary latch element. The position of the appendage and the ramp define the path of the corresponding additional latch element between the closed position and the open position.

Another advantage of the present invention is that another piece is disposed on the upper edge of the primary latching element. In this case, the appendage and the ramp of the guide also determine the path between the closed position and the open position of the respective additional latching element.

Another advantage of the invention is that the other block is guided out of its movement in a longitudinal slit parallel to the two text deletions. This ensures a fixed guidance in both directions of the accessory between the closed position and the open position.

It is also advantageous if the accessory is a roller having an axis of rotation perpendicular to the main plane. The rollers significantly reduce friction in the guide.

Another advantage of the present invention is that the locking lever is connected to the second additional latching element via the second actuator strap. This makes it possible to establish a multipoint lock on the sides of the door, for example on the door, on the middle and on the underside of the door.

Finally, it is also advantageous if the locking device according to the invention is equipped with a multipoint locking drive.

Detailed Description

On fig. 1a side schematic view of an assembly is shown, comprising a self-locking device 1 with a multipoint locking actuator 2 in a closed position. On fig. 2a side schematic view of an assembly is shown, comprising a self-locking device 1 with a multipoint lock actuator 2 in an open position. For example, the locking device 1 is arranged in a door and is delimited on one side by a cuff track 3 formed with an opening 7, wherein the primary latching element 5 can be moved through the opening 7 in the latching direction RR into the closed position (fig. 1) and back into the open position (fig. 2). Fig. 1 and 2 show the path of the primary latching element 5 from the closed position into the open position (latching direction RR) by corresponding arrows and vice versa.

The locking device 1 has a key cylinder 9, which key cylinder 9 can be used to manually trigger the locking device, for example to move the primary latch element 5 from the closed position into the open position, or vice versa, to move the primary latch element 5 from the open position into the closed position. In an alternative not shown, the locking device 1 can also be provided with an electromagnetic door opener which automatically triggers the closing process and/or the opening process without having to activate the lock cylinder 9.

In the activation step, the primary latching element 5, which is biased by the first compression spring 12, is moved into the closed position through its opening 7 and is locked therein.

In many cases, it is desirable that a door, window or some other component which locks a wall opening is not locked with a single primary latching element 5, but that at least one other additional locking device 11 with at least one additional latching element 11.1, 11.2 can also be used. However, the locking mechanism for the additional latching elements 11.1 and 11.2 can be designed as desired. Fig. 3 and 4 show a preferred embodiment that is advantageous for the invention. The respective additional latching element 11.1, 11.2 is connected by the actuator band 13.1, 13.2 to the first locking lever 15.1 or to the second locking lever 15.2.

The first locking bar 15.1 has a first longitudinal axis L1 and a main plane H which coincides horizontally with the blade in fig. 1. The second locking lever 15.2 has a second longitudinal axis L2 and a main plane H which coincides horizontally with the blade in fig. 1. The first locking lever 15.1 has a first free end 15.3, into which first free end 15.3 the actuator band 13.1 of the first additional latching device 11 engages. The second locking lever 15.2 has a second free end 15.4, into which second free end 15.4 the second actuator band 13.2 of the second additional latching device 11 engages in the present exemplary embodiment. The locking lever and the actuator band are not directly engaged with each other but are coupled by a link element (which may be up to 40cm in length).

Each actuator band can also be connected to more than one additional latching element 11.1, 11.2, respectively. The first locking bar 15.1 and the second locking bar 15.2 can be moved towards the top and the bottom in fig. 1 and 2. The first locking lever 15.1 is moved in a first direction ER, while the second locking lever 15.2 is moved in a second direction ZR, the two directions ER and ZR pointing opposite one another in the present exemplary embodiment. In the built-in state, such movement corresponds to a movement in a substantially vertical direction (towards the top or towards the bottom). In the embodiment shown in the figures, the first locking lever 15.1 moves towards the top (ER) during closing and towards the bottom (ZR) during opening, while the second locking lever 15.2 moves synchronously towards the bottom (ZR) during closing and synchronously towards the top (ER) during opening.

The primary latching element 5 moves behind a main plane transverse to the first locking lever 15.1 and the second locking lever 15.2. In the built-in state, the primary latching element 5 performs a substantially horizontal latching movement in the latching direction RR, which on the drawing means a movement to the left during closing and a movement to the right during opening. A drive element 17 in the form of an appendage or pin is formed on the side of the primary latching element 5 facing the viewer.

The locking device 1 comprises drive means for a corresponding additional latch locking device 11. In the present embodiment, the drive means comprise a first drive member 17.1 with a first locking lever 15.1 and a second drive member 17.2 with a second locking lever 17.2.

Fig. 1a depicts the first drive member 17.1 separately integrated into the locking device 1 on fig. 1, i.e. in the closed position. Fig. 1b depicts the second drive member 17.2 separately integrated into the locking device 1 on fig. 1, i.e. also in the closed position. Fig. 2a depicts the first drive component 17.1 separately integrated into the locking device 1 on fig. 2, i.e. in the open position. Fig. 2b depicts the second drive member 17.2 separately integrated into the locking device 1 in fig. 2, i.e. also in the open position.

The first drive member 17.1 comprises a first locking lever 15.1 having a principal plane H and the second drive member 17.2 comprises a second locking lever 15.2 having a principal plane H. The two drive parts in fig. 1 and 2 are arranged one after the other perpendicular to the blade horizontal or main plane H and can slide over each other during operation. In the described embodiment, the two drive parts 17.1 and 17.2 are essentially of the same shape, twisted about the horizontal direction and displaced relative to one another in the vertical direction, so that the two locking levers 15.1 and 15.2 can at least partially overlap in the built-in state.

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 the first guide 19.1 of the first locking lever 15.1 and in the second guide 19.2 of the second locking lever 15.2. In the present embodiment, the first and second guide means 19.1, 19.2 are recesses, respectively, and in particular longitudinal slits extending in a main plane H inclined with respect to the first and second longitudinal axes L1, L2. With the present invention, the angle between the first guide means 19.1 and the first longitudinal axis L1 and the angle between the second guide means 19.2 and the second longitudinal axis L2 need not be determined, but rather are approximately in the range of 30 ° to 50 °. The angle of the first guide means 19.1 with respect to the first longitudinal axis L1 may be different from the angle of the second guide means 19.2 with respect to the second longitudinal axis L2. The angle is the same in the embodiment shown in the figures.

However, the alignment of the first guide means 19.1 and the second guide means 19.2 with respect to their longitudinal axes L1 and L2 is mirror inverted. In the embodiment shown, the slope of the first guide means 19.1 for the drive element 17 is positive during the closing movement (primary latch element 5 on the left) and negative during the opening movement (primary latch element 5 on the right). In contrast, the slope of the second guide means 19.2 for the drive element 17 is negative during the closing movement (primary latching element 5 on the left) and positive during the opening movement (primary latching element 5 on the right).

The first guide means 19.1 designed as a longitudinal slit has two parallel first longitudinal edges and the second guide means 19.2 designed as a longitudinal slit has two parallel second longitudinal edges. The drive element 17 is guided on the respective first and second longitudinal edges of the longitudinal slits 19.1 and 19.2. In other embodiments, the first guiding means 19.1 and the second guiding means 19.2 may also be configured in other ways or even completely differently. It is also possible that the first guide means 19.1 and the second guide means 19.2 are designed unequally and assume various angles relative to their longitudinal axis.

In the exemplary embodiment shown, the first guide means 19.1 for the drive element 17 produces a positive slope on the path from the described closed position into the open position (direction of the arrow) (drive element retracted, downward movement), on which path the drive element 17 overcomes the positive slope, and the second guide means 19.2 for the drive element 17 produces a negative slope on the path from the described closed position into the open position (direction of the arrow) (drive element retracted, upward movement), on which path the drive element 17 overcomes the negative slope. On the way from the closed position into the open position, a relative movement takes place between the drive element 17 and the respective first and second guide means 19.1, 19.2, due to the defined guide path. On account of the horizontal movement of the primary latching element 5 (latching direction RR), the positive and negative slopes of the first guide means 19.1 and the second guide means 19.2 are overcome, which forces the respective first locking lever 15.1 to escape downwards in the vertical direction (direction of the arrow) and forces the second locking lever 15.2 to escape upwards in the vertical direction (direction of the arrow). The escape operation is enabled by the guiding means 19.1 or 19.2.

Fig. 1a presents a detailed view of the first drive component 17.1 with the longitudinal axis L1. In fig. 1b the second drive member 17.2 with its longitudinal axis L2 is displaced laterally to the left in relation to the first drive member 17.1, but in a position in which the two drive members in fig. 1 are placed on top of each other and can slide on each other. The first locking lever 15.1 has a first free end 15.3, which first free end 15.3 is designed to establish a mechanical connection with the first additional latch locking means 11. The first free end 15.3 is designed much narrower in the main plane H than the first locking lever 15.1. The first locking bar 15.1 has an expansion of approximately two times. In this region, the first guide means 19.1 is designed in the manner already described as a longitudinal slot in the first locking lever 15.1. The guide means 19.1 are arranged obliquely to the first longitudinal axis L1 and in the embodiment described extend from the lower left to the upper right. The second locking lever 15.2 has a second free end 15.4, which second free end 15.4 is designed to establish a mechanical connection with the second additional latch locking means 11. The second free end 15.4 is likewise considerably narrower in design than the second locking lever 15.2 in the main plane H. The second locking lever 15.2 has about a double expansion. In this region, the second guide means 19.2 is designed in the manner already described as a longitudinal slot in the second locking lever 15.2. The second guide means 19.2 are arranged obliquely with respect to the second longitudinal axis L2 and in the embodiment described expand from top left to bottom right.

As shown on fig. 1a and 1b, fig. 2a and 2b show the first 17.1 and second 17.2 drive parts opposite each other, but in an open position, meaning displaced in the longitudinal direction, so that the two drive parts overlap more.

Fig. 3 shows two additional latch locking devices 11 opened. Since the two additional latch locking means 11 are structurally identical and are arranged only mirror-inverted, only the upper additional latch locking means 11 on fig. 3 will be described in more detail. The upper additional latch locking device 11 has a first additional latch locking element 11.1. The latter is in the closed position on fig. 3, the primary latching element 5 also being in the closed position. The first additional latch locking element 11.1 is connected to the additional latch drive part 25 via an additional latch drive element 14, which additional latch drive element 14 is connected to the additional latch locking element 11.1 and to the first additional latch guide 16.1. The actuator bands 13.1 and 15.3 are not directly joined to each other but are coupled by link elements (which may be up to 40cm in length).

One free end of the additional latch drive member 25 again has an actuator strip 13.1 for mechanical connection with the first free end 15.3 of the drive member 15.1. The first additional latch guide 16.1 is also a longitudinal slit which is aligned according to the first guide 19.1. In this embodiment, the angle to the vertical is also the same as the corresponding angle of the first guiding means 19.1. However, this need not be the case in other embodiments. The angle can be adjusted relative to the path of the additional latching element 11.1. In order to make all functions functional, the additional latch drive element 14 engages at the top into a first additional latch guide 16.1 and at the bottom into a horizontal second additional latch guide 16.2, which is formed in the housing floor.

In this way the additional latching part 25 is moved downwards, connected to 15.3 and driven into the open position shown on fig. 4 by means of the connecting element with the drive part 15.1.

During the horizontal opening movement, the additional latch drive member 25 must escape downwards into the open position shown on fig. 4 and be displaced downwards together with the first drive member 15.1 until the open position shown on fig. 4 is reached. The additional latch drive element 14 on fig. 4 is then positioned near the other upper end of the first additional latch guide 16.1. During the horizontal closing movement, these sequences are reversed from the open position on fig. 4 into the closed position on fig. 3.

In other embodiments, the closing motion or the opening motion need not occur horizontally. The individual locking elements may have other (e.g. greater or less than 90 deg. to the vertical) directions of movement, even different from each other. However, the principle remains unchanged at all times.
