Sliding door fitting

State of the art

The invention is based on a sliding door fitting according to the preamble of the main claim.

In a known sliding door fitting of the generic type (DE-GM 91 00 963), the profile bar supporting the guide rail is mounted in the angle between the ceiling and the wall, whereby the profile bar consists of a longitudinal profile with multiple cranks in cross-section, with essentially two main legs facing the ceiling and the wall, as well as a hook-shaped profile adjoining the vertical leg at the bottom, in which the guide rail is mounted. This sliding door fitting is attached to the ceiling and/or the wall, whereby the profile bar partially surrounds the carriage. In addition, the longitudinal support of the carriage extends relatively far below the profile bar, so that the upper end of the sliding door is at a not inconsiderable distance from the profile bar.

There are various sliding door fittings that allow either ceiling or wall mounting, or both.

19.10.1995 Su/Ro iG 2841

This means that the respective installation height is determined either by the ceiling or by a selected height on the wall. A sliding door fitting is also known (EP 03 43 351) that can be mounted on a wall, although the entire sliding door fitting protrudes above the upper edge of this wall and is therefore only suitable for this type of installation.

Invention and its advantages

The sliding door fitting according to the invention with the characterizing features of the main claim has the advantage that a maximum of flexibility in the installation of the sliding door fitting is provided with a minimum of technical effort. The construction height of the sliding door fitting, namely the upper end of the sliding door, depends on the position of the profile bar that closes off the partition wall at the top. In the case of high partition walls or even partition walls up to the ceiling, the profile bar is arranged accordingly high up, whereas in the case of low partition walls or room divider walls with closed or partially closed upper sections, the profile bar is also arranged relatively low and the sliding door is also correspondingly low. Despite this advantageous special solution, it is therefore possible to mount the sliding door fitting according to the invention on the ceiling or corner from wall to ceiling, since the carriage with its upper end is not higher than the upper end of the profile bar. The cross-sectional depth of the sliding door fitting according to the invention is minimized due to the design of the partial recess of the guide rail in the profile bar, which has a positive effect on the torque acting transversely to the sliding door and acting on the roller, so that the forces required for vertical guidance of the sliding door

19.10.1995 Su/Ro
iG 2841

can be extremely low. When used as the upper end of a partition wall, the profile bar is additionally stabilized by the partition wall, especially with regard to downward deflection. Without using a partition wall, the arrangement of the guide rail on the profile bar has the greatest effect. A particular advantage of the invention is that the same fitting can be used for both glass doors, which are relatively heavy, and for normal panel doors.

According to an advantageous embodiment of the invention, the profile bar is designed as a hollow profile bar with a surface facing the carriage with an open longitudinal slot into which the guide rail is inserted and attached to the inside of the profile bar. This not only significantly reduces the width of the sliding door fitting, but also provides additional stability through the connection of the guide rail within the profile bar.

According to a further advantageous embodiment of the invention, at least one filler piece is arranged between the guide rail and the inner profile surfaces of the profile bar to compensate for the different surface profiles. This primarily ensures that slanted profile surfaces are adapted by filler pieces with corresponding slanted surfaces in such a way that a vertical or horizontal surface is created for attaching the guide rail.

According to a further advantageous embodiment of the invention, the guide rail has a cross-section in the form of an angle profile. This is preferably a standard angle profile with a right angle.

19.10.1995 Su/Ro
iG 2841

According to an alternative embodiment of the invention, the guide rail has a cross-section of a U-profile. This allows the upper free leg of the U-profile to prevent the rollers that run on the inside of the lower leg from "derailing" there.

According to a further advantageous embodiment of the invention, a profile wire (round profile) is arranged on the horizontally arranged leg of the guide rail, on which the roller runs. Such a profile wire can be very easily attached to the top of the horizontal leg of the angle profile and already has the semi-circular cross-section required for the roller. Of course, an aluminum profile could also serve as a guide rail, with the cross-section being created by an extrusion process. However, aluminum generally does not meet the requirements, so steel is usually used, which then, in combination with an aluminum guide rail, provides the required stability and strength.

According to a further advantageous embodiment of the invention, the vertical leg of the angle profile is screwed to the profile bar within the latter. This is done when using a filler piece, which is usually made of plastic, using screws that penetrate both the angle profile and the filler piece and engage in a corresponding thread in the profile bar. Gluing can also be used instead of screws, but with the disadvantage that this part of the guide rail, which is subject to wear, cannot be easily replaced. The filler piece can also serve as sound insulation, depending on the plastic.

19.10.1995 Su/Ro
iG 2841

According to an advantageous embodiment of the invention, which is also claimed for itself, the profile bar is designed as a hollow profile bar, with a core profile tube of square cross-section, with diagonal webs branching off diagonally at the outer corners of the core profile tube and with outer walls connecting the outer ends of the diagonal webs at right angles to one another, so that channels of trapezoidal cross-section are formed through the walls of the core profile tube, the diagonal webs and the outer walls, with one of these outer walls being slotted lengthwise to accommodate a filler piece and the guide rail and at least one of the other outer walls serving to fasten the profile bar. Such a hollow profile bar is known per se (DE-OS 42 44 602). Corresponding fastening means for partition walls and the like are also known.

According to a further advantageous embodiment of the invention, the guide rail rests with its horizontally running underside on a profile edge of the profile bar. This creates a particularly stable fastening, since the guide rail rests on the edge of the profile bar formed by the longitudinal slot along its entire length, and is screwed or connected to the profile bar via the vertical guide rail section. Such a connection can bear particularly high loads.

According to a further advantageous embodiment of the invention, a locking device is provided which acts in the vertical direction and extends in the horizontal direction and prevents the carriage from derailing from the guide rail, whereby, according to a special embodiment, the locking device has a bolt arranged on the carriage and extending in the direction of the guide rail, which

19.10.1995 Su/Ro
iG 2841

a stop rail that is fixedly connected to the guide rail in the sliding direction. Such

Locking devices designed to prevent the carriage from derailing from the guide rail are known in many different ways. The problem is usually when putting such a locking device into operation when the sliding door cannot be placed on the guide rail from the long side, but the carriage has to be placed on the guide rail from above. Usually a tongue connected to the carriage and gripping under the guide rail is then subsequently mounted, which involves a considerable amount of effort. By using a bolt that only comes into its working position after the carriage has been placed on the guide rail, the installation of the sliding door is made much easier, which is particularly important when it is a heavy door, for example one made of a pane of glass.

According to a further advantageous embodiment of the invention, the stop rail is part of the profile bar that supports the guide rail. In particular, if this profile bar, as provided above according to an embodiment of the invention, has a longitudinal slot with a corresponding edge, this edge can serve as a stop rail.

According to a further advantageous embodiment of the invention, the bolt has a spring-loaded lock latch, which engages in the locking position after the sliding door has been hung. Since the bolt protrudes in the direction of the track when viewed from the carriage, it is first pushed in when the sliding door is hung, and then, after the carriage has rested on the track, it snaps under the stop rail running perpendicular to the stroke direction of the bolt. In addition,

19.10.1995 Su/Ro iG 2841

The advantage is that such a lock latch is a commercially available series product and therefore costs very little.

According to a further advantageous embodiment of the invention, the bolt has an axially displaceable and rotatable bolt with a radial drive pin guided in a cylinder bore, with recesses in the wall of the cylinder bore for the drive pin to engage. Such bolts are known as so-called stable door bolts and have the advantage that they remain in the unlocked or locked position, even when they are spring-loaded. This is an advantage when removing the door because the bolt then remains in the unlocked position so that the sliding door and its carriage can be lifted off the guide rail.

According to a further advantageous embodiment of the invention, the carriage has an angle profile, to the vertical leg of which the rollers are attached and the horizontal leg of which grips under the guide rail in order to prevent the carriage from derailing. In this way, derailment protection is provided in a very simple way, namely by just one component. However, the carriage or the sliding door can only be "threaded" from the long side of the guide rail.

According to a further advantageous embodiment of the invention, the carriage has a profile bar as a support element, the cross-section of which is the same as that of the profile bar supporting the guide rails. Such use is particularly possible when the sliding doors are wall panels that can be attached to corresponding profile bars in a manner known per se (DE-OS 42 44 602). According to the invention, a pane of glass can of course also serve as a partition wall.

19.10.1995 Su/Ro
iG 2841

To attach the profile bar to the glass pane, it can be slotted lengthwise.

According to a further advantageous embodiment of the invention, the fastening of the carriage to the sliding door has an adjustment device for adjusting the height of the sliding door. The position of the sliding door can thus be adjusted on site.

According to a further advantageous embodiment of the invention, the adjustment device has at least one vertically arranged bolt that can be inserted into the carrier part and has a thread at the upper end. The position of the bolt with respect to the carrier part can be adjusted using nuts guided in the thread.

According to a further embodiment of the invention, a support plate is arranged in the lower section of the carriage at a distance from the guide rail or the profile bar, which prevents the carriage from tipping over and thus possibly becoming unhooked in the event of a failure of the sliding door guide (glass breakage), whereby the support plate is angled upwards and interacts with the underside of the guide rail with its upper front edge.

Further advantages and advantageous embodiments of the invention can be found in the following example description, the drawing and the claims.

Description of the embodiments

As shown in cross-section in Fig. 1, the sliding door fitting according to the invention has a profile bar 1 with a longitudinal slot 2 into which a guide rail 3 is inserted and screwed to the profile bar 1 via screws 4 and the interposition of a filler piece 5. Rollers 6 run on the guide rail 3 and are attached to a carriage 7. The profile bar 1 is mounted on a glass pane 8 serving as a partition wall.

arranged. A glass pane 9 also serves as a sliding door, which can be moved parallel to the fixed glass pane 8 via the sliding door fitting.

The profile bar 1 has an inner square 11, from the corners of which diagonal webs 12 lead to the inner corners of an outer casing 13, which is also square, and on one long side of which the slot 2 is arranged. In addition, a slot 14 is provided for receiving the glass pane 8. The slot 14 and possibly also the slot 2 are only subsequently incorporated into the profile bar 1, which is preferably made of aluminum, depending on the type of partition wall or the desired fastening between the profile bar and the partition wall.

In this embodiment, the profile bar 1 is connected to a ceiling 17 via a strip 15 and a U-rail 16. This also provides additional stability against tilting, which may only be achieved unsatisfactorily with the glass pane 8.

The carriage 7 has, as shown in Fig. 2 and 3, two glass door hinges 18 with heads 19, via which the glass pane 9 serving as a sliding door is connected to the carriage 7. In addition, the carriage 7 has a support element 21, which has recesses on the side facing away from the rollers 6 to reduce weight, but also to make it easier to attach the glass door hinges 18. An angle profile piece 23 supporting the rollers 6 is screwed onto the support element 21 by means of screws 22. The angle profile piece 23 has a horizontal free leg 24 which engages under the guide rail 3 (Fig. 1) in such a way that the rollers 6 cannot derail from the guide rail 3. A round rod 25 is used to guide the rollers 6 on the guide rail 3, which is mounted on the front

19.10.1995 Su/Ro iG 2841

protruding leg of the guide rail 3 and which engages in a corresponding semicircular groove 26 (Fig.3) of the rollers 6.

In Fig. 4, the glass panes 8 are shown as a static wall and 9 as a sliding door in plan view, with the glass pane 8 being set in a profile bar 1 on all four sides, while the glass pane 9 is supported by the glass bands 18 and the carriages 7 by the profile bar 1 arranged continuously above, in the manner described in Fig. 1, 2 and 3.

In the second embodiment shown in Fig. 5, the profile bar 31 shown in cross section on the right in the picture is the same as in the first embodiment. Instead of the glass pane arranged at the bottom, which serves as a partition wall, a panel wall 28 is provided here, which is connected to the profile bar 31 via various anchors 29, whereby these anchors 29 engage behind the inside of the outer casing 13. The carriage shown on the left in the picture has a rod-shaped support element 32, which corresponds in cross section to the profile bar 31, from which a panel-shaped sliding door 34 hangs via anchors 33 and to which the angle profile piece 23 with a free leg 24 is screwed via screws 35 and the intermediate storage of a filler bar 36, on which in turn the rollers 6 are arranged.

In Figs. 6 to 10, different variants of a locking device preventing the carriage from derailing from the guide rail are shown. Figs. 6 and 7 show the same locking device in the open and locked state. The same applies to Figs. 9 and 10. All devices have in common that a bolt 37 arranged on the carriage 7 and extending in the direction of the guide rail 3 has a

19.10.1995 Su/Ro 12

iG 2841

The guide rail engages under the stop rail 38 which is fixed to the guide rail. To open and close the locking device, the bolt 37 is moved horizontally away from or towards the stop rail 38.

In Fig. 11 and 12, a carriage 39 is shown which has a height adjustment for the sliding door 41. Two vertical bolts 42 are arranged on the carriage 39 and are attached to the sliding door 41 via heads 43. The upper end of the bolts 42 is equipped with a thread. The distance between the sliding door 41 and the carriage 39 can be varied using nuts 44, the thread of which engages with that of the bolt 42, and thus the height of the sliding door can be adjusted in relation to the floor.

In Fig. 13, the guide rail 45 is U-shaped, with the round bar 25 attached to its lower free leg and the upper free leg serving as a safeguard against the wheels 6 derailing from the round bar 25. In addition, a support plate 47 pointing towards the profile bar 1 is attached to the underside of the carriage 46, the free end of which is angled upwards and has only a small free gap to the underside of the guide rail 45. As soon as the sliding door is no longer guided on its underside, for example in the event of glass breakage, this support plate prevents the carriage 46 from tipping over and thus from possibly becoming unhooked by hitting the guide rail 45.
