Description

The present invention relates to a sliding door assembly, comprising a stationary frame, a horizontally displaceable door leaf and a locking device for locking the door leaf to the frame, wherein the locking device comprises a locking element and cooperating with the locking element bolt receptacle.

A sliding door arrangement of the type mentioned is from the DE 26 03 240 A1 known. Sliding door assemblies or tilt-and-slide door assemblies that are used as part of building glazing employ locking devices that include a latch bolt and a bolt receptacle cooperating with the latch bolt. These can be brought into a closed position locking the hinged door and into a release position which releases the hinged door.

However, in known sliding doors is problematic that locking bolt and bolt receptacle are often not sufficiently in alignment with each other, so that they meet when opening and / or closing the hinged door under increased wear on each other, but at least strip each other and only then "aligned". A permanent and reliable operation is not guaranteed. A further problem is that such gullwing doors in the closed state often insufficiently seal against the frame, so that moisture and cold can penetrate into a building. This is unfavorable from an energetic point of view. Solutions for this are not, at least not sufficiently available, especially in the various types of door leaf and frame - aluminum, wood and PVC - a large number of different hardware components exists. Therefore, adjusting the door leaf to a frame is limited to manual reworking by machining, for example filing the locking bolt. This is not reversible and weakens the machined elements.

The present invention is therefore the object of a sliding door arrangement of the type mentioned in such a way and further develop that regardless of the type of frame and / or door a permanently reliable and energetically favorable use is possible.

The sliding door assembly according to the invention solves the above object in that the bolt receptacle is assigned to a door element arranged on the rail element and that the rail element is adjustable by an adjustment in at least a first adjustment direction.

In accordance with the invention, adjustment of the rail element can be carried out in a simple manner with the adjustment device. Thus, the alignment between the locking element and bolt receptacle can be precisely adjusted, with such an adjustment process as often repeatable and thus reversible. By a precise adjustment of the alignment between the locking element and the bolt receptacle occurring between these two components wear can be largely avoided, with a shock and / or smooth closing of the door leaf can be achieved. This contributes to an increase in the service life of the sliding door assembly, since the wear occurring within the locking device is reduced to a minimum. As a result, a better seal or a better closing of the door leaf is achieved with respect to the door frame, as maintained by reducing the wear of the locking element and cooperating with the locking bolt latch receptacle their accuracy of fit. Thus, regardless of the type of frame and / or door a permanently reliable and energetically favorable use is guaranteed. Due to the arrangement of the adjustable rail element on the frame whose setting is independent of a lock causing a gear mechanism, for example. A wing-side tie rod allows. An impairment of the transmission mechanism can thus be avoided.

The locking element may be formed as a locking bolt or hook bolt. The bolt receptacle can be designed accordingly as a bolt receptacle with a passage with schlossförmigem cross-section or as a slot for a hook latch.

Advantageously, the first adjustment direction of the rail element may be oriented orthogonal to a plane formed by the frame. Based on the direction of displacement of the door wing thus adjustment of the rail element in the lateral direction is possible. Thus, in a simple way, the main cause of impairment of the closing process, in particular an audible as a noise and noticeable as a hook strip of the wing when entering the locking element, be eliminated.

In concrete terms, the adjusting device may have a first adjusting element, which may be pivotable about an eccentrically arranged pivot axis with respect to the geometric center of the first adjusting element. The geometric center may be in the case of a rotationally symmetrical body on a center line or line of symmetry. As a result, an actuating element is provided with simple structural means, which allows a stepless adjustability of the rail element, by pivoting the first control element. For a possible low-wear and sensitive adjustment process, the actuator can be made of plastic or Teflon.

Specifically, the pivot axis can cut the first actuator. Thus, an actuator is realized with a small footprint. This can be readily arranged in the region of the rail element or below the rail element. Due to the low lever arm between the geometric center of the first control element and the pivot axis of the first control element, the torques acting on the control element are low. The adjustment made is thus retained. Conveniently, the first adjusting element for adjusting the rail element and / or for holding a made adjustment of the rail element with at least one protruding from the rail element profile element, in particular with at least one side wall of the rail element in contact. In this way, the assembly or attachment of the rail member is simplified by an adjustment made by the first actuator by the rail element with the projecting profile element or the side wall of the rail element is guided or applied to the first control element and then attached to its attachment points on the frame. Preferably, the first actuating element with two projecting from the rail element profile elements, in particular two side walls of the rail element, in contact. In other words, the first actuating element can preferably be accommodated between two profile elements, in particular two side walls, of the rail element. As a result, a backlash-free installation and / or a play-free adjustment of the rail element is possible. The rail element may be a Umprofil for a frame. The Umprofil can accommodate a control element in its interior.

In an advantageous manner, the first control element may have an engagement section, in particular a polygon socket, for an adjustment tool. As a result, an adjustment of the first control element is made possible with a simple handling. For access to the first control element, only a slightly larger opening in the rail element is required relative to the adjustment tool. Ingress of dirt and resulting wear of the first control element can thus be reduced to a minimum. In which Inner polygon can be a hexagon socket. This makes a simple adjustment with commercially available tools possible.

Advantageously, the pivot axis can be defined by a screw locking the first adjusting element to the frame, in particular by a self-tapping screw. Hereby an attachment of the first actuating element and a pivot axis are created by simple structural means. An attachment of the first actuating element to the frame is made possible in a simple manner, regardless of the type of frame.

Specifically, the first actuator may be formed as a cylindrical body. This allows a sensitive and infinitely variable adjustability of the rail element, since the adjusting element rests against at least one profile element projecting from the rail element during a setting process.

In an advantageous manner, the adjusting device can have a further adjusting element, by means of which the rail element can be adjusted in a second adjusting direction. The presence of two adjustment directions provides greater flexibility in mounting the frame and adjusting the locking device. Due to the ability to compensate for deviations or tolerances in two directions, the assembly of the locking device and thus the sliding door assembly as a whole is considerably simplified.

In concrete terms, the second adjustment direction can be oriented in the direction of displacement of the door leaf. This allows a precise adjustment of the contact pressure between Door leaves and frames are made. An improved sealing of the door leaf to the frame, namely in the closed position of the door leaf, can be achieved. This contributes to an energetically favorable operation of the door leaf and thus the sliding door assembly as a whole.

The further adjusting element can be designed as an adjusting screw cooperating with the rail element, in particular as a grub screw, for adjusting the distance of the rail element from the frame. Thus, an adjustment of the contact pressure with simple structural means is possible. The adjusting screw serves as an adjustable stop, with which the spacing between rail element and frame can be adjusted.

In a particularly advantageous manner, the adjusting screw can be arranged in a passage formed in the first adjusting element and provided with an internal thread, with an external thread of the adjusting screw corresponding to the internal thread of the passage. As a result, a particularly compact adjusting device is realized, whereby a favorable power flow between the individual control elements thus the rail element and / or the frame can take place. In this case, a low-friction adjustment is realized because the screw does not press directly against the rail element, but depending on screwing / screwing the first control element, in particular the cylindrical body, presses against the rail element. By screwing the adjusting element presses this against the frame, so that the first adjusting element and thus also the rail element are spaced from the frame. As a result, the contact pressure is reduced.

Specifically, the adjustment of the rail element in the direction of the door leaf can be at least one, preferably at least two, more preferably four millimeters. This provides a sufficient adjustment range, so that the contact pressure between the door leaf and the frame can be set precisely.

Conveniently, the adjustment of the rail element along the first adjustment direction, in particular starting from a central position in preferably both directions, amount to one millimeter. By this adjustment a sufficient alignment of locking element and bolt receptacle is possible.

One embodiment of a sliding door arrangement is in FIG. 1 shown schematically and identified there by the reference numeral 10. The sliding door assembly 10 includes a frame 12 shown in dashed lines, which is fixed in place and building. The frame 12 preferably has a particular glazed fixed field 14, which is marked in the drawing with a diagonal cross.

The frame 12 also serves to arrange a door leaf 16, which is displaceable between a closed position and an open position in which the door leaf 16 overlaps the fixed field 14 in sections.

The door leaf 16 is in particular a lifting / sliding door, which is not only horizontally displaceable, but can also be raised and lowered. In a lowered state of the door leaf 16, an effective sealing of the door leaf 16 in the frame 12 is simplified. In a raised state of the door leaf 16, this can be moved horizontally.

The door leaf 16 has a sash 18 which defines a sash box 20. The wing panel 20 may be formed for example by a glazing. Of the Wing frame 18 has an upper profile 22, a lower profile 24 and vertical profiles 26 and 28.

The vertical profile 26 abuts in a closed state of the door leaf 16 on a vertical frame part 30 of the frame 12. This vertical profile 26 is understood in the context of the present invention as a "wing-side" profile. The frame part 30 is understood as a "frame-side" profile.

In a closed state of the door leaf 16, the vertical profile 26 and the vertical frame part 30 of the frame 12 may be locked together. For this purpose, a locking device 32 is provided, which has a locking element 34 and a cooperating with the locking element 34 - here only schematically illustrated - locking receptacle 36 has. The latch receptacle 36 is assigned to a rail element 38 arranged on the frame 12. The bolt receptacle 36 is formed as a passage, recess or opening in the rail member 38.

The FIGS. 2a and 2b each show a the bolt receptacle 36a, 36b-containing portion of the rail member 38a, 38b, and that from the viewing direction of the locking element 34. If the locking element 34 is within the latch receptacle 36, a lock can be made. This is done via the door side mounted and movable latch 34, which is coupled to a transmission element, such as a pull rod (not shown). Thus, the latch 34 along the vertical profile 26 is displaced. About mounting points 46, which may be formed in the form of passages, the rail member 38 is attached to the frame 12.

The latch receptacle 36a may be formed as a passage in the form of a slot according to a first embodiment and serve to receive a hook bolt ( 2a ). The bolt receptacle 36b may be formed according to a second embodiment as a passage with a lock-like cross-section and serve to receive a locking bolt ( 2b ).

To adjust the rail member 38, an adjustment 48 is provided. The adjustment device 48 is arranged between the rail element 38 and the vertical frame part 30 of the frame 12. The rail member 38 is formed as Umprofil 39. By adjusting 48, the rail member 38 is adjustable in a first adjustment direction 50. The first adjustment direction 50 is oriented orthogonal to a plane formed by the frame 12.

The adjusting device 48 has a first adjusting element 52, which is pivotable about a - with respect to the geometric center 54 of the first adjusting element 52 - eccentrically arranged pivot axis 56. The center 54 lies on a midpoint or line of symmetry 54. The pivot axis 56 intersects the first actuator 52.

The pivot axis 56 is defined by a first adjusting element 52 on the frame 12 arresting screw 58. The screw 58 may be a self-tapping screw. To facilitate adjustability of the first adjusting element 52, this has an engagement section 60 for an adjustment tool. The engagement portion 60 is formed as a hexagon socket 62.

The adjusting device 48 has a further adjusting element 64, through which the rail element 38 in a second Setting direction 40 is adjustable. The second adjustment direction is oriented in the direction of displacement 40 of the door leaf 16. In the FIGS. 2a and 2b the second setting direction projects orthogonally out of the plane of the drawing.

The further adjusting element 64 is designed as a cooperating with the rail member 38 adjusting screw 66, which serves to adjust the distance of the rail member 38 from the door leaf 12. The adjusting screw 66 may be formed in particular as a grub screw.

The adjusting screw 66 is arranged in a passage 68 formed in the first adjusting element 52 and provided with an internal thread. An internal thread of the adjusting screw 66 corresponds to the internal thread of the passage 68. Depending on the screwing or screwing depth of the adjusting screw 66, the distance of the rail member 38 relative to the frame 12 or the vertical frame member 30 can be adjusted. The first adjusting element 52 is designed as a cylindrical body 70. The first adjusting element 2 is made of plastic.

FIG. 3 shows a side, partially sectioned view of the adjuster 48 in the installed state. By the screw 58, the first adjusting element 52 on the frame 12, in particular on the vertical frame part 30, fixed. Serving as another actuator 64 screw 66 is screwed into the passage 68. The cylindrical body 70 serving as the first adjusting element 52 is arranged between the frame 12 or the vertical frame part 30 and the rail element 38.

The first adjusting element 52 is in contact with a profile element 72 protruding from the rail element 38. The profile element 72 is formed as a side wall 74 of the rail member 38.

• Zum Einstellen des Schienenelements 38 in der ersten Einstellrichtung 50, die orthogonal zu einer durch den Rahmen 12 gebildeten Ebene orientiert ist, kann bei gelöster Schraube 58 das erste Stellelement 52 oder der zylinderförmige Körper 70 um die Schwenkachse 56 verschwenkt werden. Dies kann mittels eines Einstellwerkzeugs erfolgen, das mit dem Eingriffsabschnitt 60, der als Innensechskant 62 ausgebildet sein kann, zusammenwirkt.

An adjustment of the rail element 38 can proceed as follows:

• For adjusting the rail element 38 in the first adjustment direction 50, which is oriented orthogonal to a plane formed by the frame 12, the first adjusting element 52 or the cylindrical body 70 can be pivoted about the pivot axis 56 when the screw 58 is loosened. This can be done by means of an adjustment tool, which cooperates with the engagement portion 60, which may be formed as a hexagon socket 62.

In order to adjust the rail element 38 in the direction of displacement 40 of the door leaf 16, the adjusting screw 66 serving as a further adjusting element 66 must be screwed in as desired. In the in FIG. 3 illustrated situation, the adjusting screw 66 does not protrude from the cylindrical body, so that the distance between the rail member 38 and the frame 12 or the vertical frame member 30 are predetermined by the cylindrical body 70. The force acting in the closed state between the door leaf 16 and frame 12 contact pressure is maximum.

If the adjusting screw 66 is screwed further into the passage 68, the end of the adjusting screw 66 facing the frame 12 or the vertical frame part 30 comes into contact with the frame 12 or the vertical frame part 30. The cylindrical body 70 is then by the amount to the the adjusting screw 66 protrudes from the body 70, spaced from the frame 12 or the vertical frame member 30. The contact pressure between the door leaf 16 and frame 12 is thus reduced.

After making the adjustment in the direction of displacement 40 of the door, the screw 58 can be screwed to fix the adjustment made.

The cylindrical body 70 serving as the first adjusting element 52 is in contact with both side walls 74. This allows a play-free and sensitive adjustment process in the first adjustment direction 50. By screwing the screw 66, a setting of the profile element 38 is also possible in the direction of displacement 40 of the door leaf.

With regard to the description of further elements, reference is made to the description of the preceding figures, wherein identical or functionally identical elements are provided with identical reference numerals.
