Description

The invention relates to a device for locking a door frame movable in a door frame of a door, in particular sliding door.

In addition to fixed window solutions for corner walls and house corners, the modern architecture also wants to access sliding door solutions, whereby no wall or support element should be provided on the corner itself. In other words, the corner itself should be designed as a window or door.

Furthermore, cuff arrangements of sliding doors should be available, in which two movable door leaves of a sliding door in a plane in opposite directions and the door leaves "push-to-push" are closable.

Conventional sliding doors are often designed to provide a two-piece locking device for locking in a closed condition. Here, a part is housed in a movable door, the second part in the door frame, which is connected to masonry. The part housed in the frame is often large and heavy. The accommodated in the frame second part of the sliding door is therefore often not suitable to be re-installed in a sliding door.

It is an object of the invention to overcome the disadvantages mentioned and to provide a sliding door arrangement which is suitable for example for a corner arrangement in a house, is lightweight and has a slim design.

• einen Hauptteil, welcher im montierten Zustand der Vorrichtung im Türrahmen der Tür angeordnet ist und ein Antriebsmittel zum Bewegen eines Schiebekörpers in einer ersten Richtung innerhalb des Hauptteils aufweist, und
• einen aus dem Hauptteil herausragenden Hubkörper, welcher in dem Hauptteil längs einer quer zur ersten Richtung verlaufenden Hubrichtung beweglich gelagert ist, wobei der Hubkörper ein quer zu der Hubrichtung vorspringendes Betätigungselement aufweist, welches dazu eingerichtet ist, in eine Schließvorrichtung des Türblatts einzugreifen, wenn das Türblatt in eine schließende Stellung im Türrahmen gebracht wird, und die Schließvorrichtung durch eine Bewegung entlang der Hubrichtung zu verriegeln,

wobei der Schiebekörper und der Hubkörper über eine Nutführung miteinander gekoppelt sind, welche eine Bewegung des Schiebekörpers in der ersten Richtung in eine Hubbewegung des Hubkörpers entlang der Hubrichtung umsetzt.The object is achieved by a device of the aforementioned type, the device comprising:

• a main part, which is arranged in the assembled state of the device in the door frame of the door and has a drive means for moving a sliding body in a first direction within the main part, and
• a protruding from the main body lifting body, which is movably mounted in the main part along a direction transverse to the first direction stroke direction, wherein the lifting body a transversely to the lifting direction projecting actuating element which is adapted to engage in a closing device of the door leaf when the door leaf is brought into a closing position in the door frame, and to lock the closing device by a movement along the stroke direction,

wherein the sliding body and the lifting body are coupled together via a groove guide, which converts a movement of the sliding body in the first direction into a lifting movement of the lifting body along the stroke direction.

As a result, a device is provided which can actuate a closing device, for example from above. The locking device can thus be arranged between two movable door leaves.

In a further development of the invention, the groove guide includes a groove running obliquely to the first direction and the stroke direction, preferably a straight groove, and a sliding element arranged therein. As a result, a conversion of a horizontal movement is achieved in a vertical movement in a vertical movement,

It is advantageous if the sliding body has two side parts arranged on both sides of the lifting body, in each of which an obliquely to the first direction and the stroke direction groove, preferably straight groove, is formed, and the lifting body has two opposing pins as a sliding element, which in each engage one of the grooves. This allows a symmetrical arrangement of the components, which avoids unwanted torque in lateral connections.

It results in a simple construction and assembly when the pins are designed as ends of a running through the lifting pin as a sliding element.

A reliable definition of the lifting movement can be achieved, for example, if adjacent to the lifting body a guide body is arranged, which is attached to the main body and has an elongated closing guide with a longitudinal extent, in which a lifting member mounted on the lifting body engages and the lifting body along the longitudinal extent of the closing guide is movable in the stroke direction.

In a further development of the invention, in the mounted state of the device, the actuating element is arranged projecting into an opening of the closing device in the door. The actuating element engages only in the closing position of the door leaf in the closing device of the door leaf.

It can be a simple and space-saving solution to achieve when the drive means comprises a linear drive for a push rod to which the sliding body is attached.

It is possible to determine a simple monitoring of the end positions of the lifting body via the position of the drive, if the drive means associated sensor elements which each detect an end position of the movement of the sliding body along the first direction, wherein the sensor elements are preferably designed as a reed switch.

• a main part, which is arranged in the assembled state of the device in the door frame of the door and has a drive means for moving a sliding body in a first direction within the main part, and
• a lifting body projecting from the main part, which is mounted movably in the main part along a lifting direction extending transversely to the first direction, the lifting body having an actuating element projecting transversely to the lifting direction, which is adapted to move the closing device of the door leaf by a movement along the lifting direction to lock,

wherein the sliding body and the lifting body are coupled together via a groove guide, which converts a movement of the sliding body in a lifting movement of the lifting body along the stroke direction.

The drive means serves to displace the sliding body, ie to actuate the locking device. It should not be confused with a possibly additionally provided motor for moving the door leaf, ie for closing or opening the passage, which can be closed by the sliding door.

It is known to those skilled in the art that the drive means in the form of a linear motor additionally requires an electrical control, which will not be discussed further.

With reference to Fig. 1 to Fig. 12 Now, an embodiment of the invention will be explained in more detail. In particular, important parts are shown for the invention in a sliding door, it being understood that a sliding door contains many other parts, not shown. For clarity, therefore, for example, rollers, roller guides, suspensions, sensors or control electronics are not shown.

Fig. 1 shows a sliding door assembly with two sliding doors 1, 2 according to the invention, which have in the form of a corner arrangement to each other, for example, a right angle. The sliding doors can be moved on both sides along the directions 5 and 6 respectively. If both sliding doors are open, the released corner area has no construction elements to which locking devices are attached. The to Lock provided closing devices are mounted in the end edges of the movable door of the two sliding doors 1, 2.

An alternative, not separately shown embodiment may be a faceplate arrangement of two mutually opposite movable door leaves, which on the same locking principle of in Fig. 1 sliding door arrangement shown.

Fig. 2 shows a cross section of the sliding door 1 in a sectional plane 8 according to the Fig. 1 , wherein only the uppermost part of the sliding door 1 is shown. It can be seen that a movable wing in the form of a door leaf 20 is mounted in a door frame 30. There are covers 3, 4 of the frame profiles of the door 1 can be seen.

3 and 4 make a main part 31 of the locking mechanism of the sliding door construction according to the Fig. 1 which is integrable in the door frame 30.

The main part 31 is arranged in the assembled state of the device in the door frame 30 of the door 1. A drive means 50 serves to move a sliding body 40 in a first direction 5 within the main part 31.

The drive means 50 comprises in this example a housing 51 with a linear drive in the form of a gear motor 52 and a push rod or a spindle 53. On the push rod, a sliding body 40 is attached.

The drive means 50 may be associated with sensor elements which each detect an end position of the movement of the sliding body 40 along the first direction 5. The sensor elements are preferably designed as reed switches.

The individual components can be connected to each other by means of various screws or nuts, as in Fig. 4 indicated.

The sliding body 40 comprises in this example two side parts 43, 44, which each have a, preferably on the inwardly facing side, groove 41 and 42. The side parts 43, 44 are connected by a nut 54, the nut 54 being provided to receive one end of the spindle 53. In combination, the sliding body 40 is U-shaped and also has cover plates 56 and 57 and an end cover 58.

The main part 31 further comprises a holder 59 for attachment in the door frame 30.

In addition, the main part 31 has a protruding from the main part 31 lifting body 33 which is movably mounted in the main part 31 along a direction transverse to the first direction 5 stroke direction 7.

The locking device further comprises a lifting body 33 which projects downwardly from the main part 31 and serves to actuate the device.

The lifting body 33 has a transverse to the lifting direction 7 projecting actuator 34 in the form of a bolt. The bolt serves as a locking bolt which is adapted to engage in a closing device 21 of the door leaf 20 when the door leaf 20 (FIG. Fig. 11 and 12 ) is brought into a closing position in the door frame 30 in order to lock the closing device 21 by a movement along the stroke direction 7.

The sliding body 40 and the lifting body 33 are coupled together via a groove guide, which converts a movement of the sliding body 40 in the first direction 5 in a lifting movement of the lifting body 33 along the stroke direction 7. An optional guide block 55 is disposed between the nut 54 and the lifting body 33.

The groove guide includes an obliquely to the first direction 5 and the stroke direction 7 extending groove 41, 42, preferably straight groove, and disposed therein a sliding element 35. The lifting body 33 has, as a sliding member 35 has two opposing pins, which in each case one of the grooves 41, 42 intervene. In this example, the pins are formed as ends of a running through the lifting body 33 pin as a sliding member 35.

The sliding body 40 has two on both sides of the lifting body 33 arranged side parts 43, 44, in each of which an obliquely to the first direction 5 and the stroke direction 7 extending groove 41, 42, preferably straight groove, is formed.

Adjacent to the lifting body 33, a guide body 32 is arranged in parallel, which is attached to the main part 31 and fixed there. The guide body 32 has an elongate closing guide 37 with a longitudinal extent, in which a on the lifting body 33rd mounted lifting guide element 36 engages and the lifting body 33 along the longitudinal extent of the closing guide 37 in the stroke direction 7 is movable.

The elongate closing guide 37 forms a groove in which the lifting guide element 36, for example a cylinder with a mushroom-shaped end, can slide in the lifting direction 7 during a lifting movement. The length of the closing guide 37 limits the actuating travel of the closing device 21.

In the assembled state of the device, the actuating element 34 is arranged projecting into a corresponding opening of the closing device 21 in the door.

The actuating element 34 engages only in the closing position of the door leaf 20 in the closing device 21 of the door panel 20 a.

For a good lubricity of the movable components, for example, a first group of components, such as the guide body 32, the side parts 43, 44 with the grooves 41 and 42 and the guide block 55, be made of brass or anodized aluminum. A second group of components, such as the lifting body 33, the actuating element 34 and the sliding element 35, may be made of stainless steel.

It is particularly advantageous if the first group of components is made of a softer material than the second group of components because of the desired higher mechanical strength.

Fig. 5 to 7 show the device with respect to the position of the lifting body 33 and the actuating element 34 in an unlocked state, which corresponds to a first end of the intended course of the linear movement. The lifting body 33 is in a position in which the outer edges of the lifting body 33 coincide with those of the adjacently arranged guide body 32. The lifting body 33 is thus in a, in the stroke direction 7 "retracted" state.

A rotational movement generated by the gear motor 52 is transmitted by means of the spindle 53 to the nut 54 and converted into a linear movement in the first direction 5 of the sliding body 40.

In Fig. 6 is the sliding member 35 can be seen, which is located at the upper end of the groove 41. It can also be seen that the lifting body 33 is "retracted" to open the door 1, 2.

The linear movement causes the slider 35, which is mounted in the two grooves 41, 42, to move in the stroke direction 7. As a result, the lifting body 33 can be raised or lowered. The movement of the lifting body 33 is limited by the size and size of the closing guide 37, since the Hubführungselement 36 attached to the lifting body 33 engages in the closing guide 37 and the lifting body 33 in the intended path of movement, which is defined by the closing guide 37 leads.

A monitoring of the end position of the linear movement can be done by sensors, such as inductive or mechanical switches, but also optical sensors, as known in the art.

The gear motor 52 can be controlled via a corresponding control, which is not shown in the figures.

Fig. 8 to 10 show the device with respect to the position of the lifting body 33 and the actuating element 34 in a locked state, which corresponds to a second end of the intended course of the linear movement. The first end and the second end limit the intended trajectory of the linear movement.

In Fig. 9 is the sliding member 35 can be seen, which is located at the lower end of the groove 41. Furthermore, it can be seen that the lifting body 33 is "extended" for a closing operation.

Fig. 11 and 12 each show a view of the sliding door assembly of the two sliding doors 1 and 2 in the unlocked and locked state. The actuating element 34 engages by means of the lifting body 33 in the closing device 21 located on the door side. The locking device 21 of the door 1 locks on a lock plate 60 of the door 2 both doors each other.
