Description

The invention relates to a sliding door device with upper rails to be installed in a building opening, in which sliding doors (sliding leaves) are suspended.

It is known (as can be seen, for example, from GB-A-2 102 867) in such sliding doors to bend or bend additional running rails from a main rail running along the building opening and / or to branch off parallel to the main running rail, in which guide rollers or the like. can be moved. A sliding door (a sliding door leaf) is equipped in its outer end areas with upwardly projecting guide rollers, which all run in the main running track when the sliding door front is closed.

As soon as sliding doors or sliding door leaves are opened, a guide roller arranged at one end remains in the main track, while at the other end of the sliding door fixed guide rollers in additional parallel or the like. Swing in the secondary rails running to the main running track.

For this purpose, secondary rails are attached to the main running track at an acute or right angle, in the grooves (running spaces) of which the guide rollers run in and rest there when the door leaf is open.

In the previously known running rails, the running grooves adjoin one another at right angles or at an acute or obtuse angle, so that corners and edges arise at which the guide rollers can bump.

The object of the invention is to provide a sliding door device (sliding door), in the special guide devices or the like. are installed, which act as switches, tying, tilting or the like. the guide rollers prevented.

This object is achieved in a sliding door device of the type mentioned in that projecting in the running rollers receiving, at an angle to each other (branch angle) guide pins or pegs, which form a turn like a switch for the guide rollers, so that these guide rollers without teasing or to cant go through the turns.

These switch pins or pegs to be installed in the running spaces of the running rails can, depending on the type of guide rollers, be inserted in the main running rail and the secondary running rails in the bending areas at suitable directions and distances. Stand there these switch pins or pegs, which are fastened in their upper region in the corresponding upper running rail, down in front into the running space or spaces and reach into the space between two adjacent guide rollers on which the door leaf hangs.

Therefore, the diameter of the switch pins or pins is preferably only slightly smaller than the space between two adjacent guide rollers, which in turn are attached to the carriage carrying the door leaf.

The guide rollers thus receive an advantageous guide in the bends (bends) so that they do not tilt or bump and thus the door leaf or the like. can be opened or closed properly.

The use of trolleys as connecting devices between the door leaf and guide (holding) rollers results in excellent running properties. The guide rollers offer the like through the above guide pins according to the invention. a bumpless movement in the angled areas of the tracks.

Further features of the invention emerge from the subclaims.

The invention extends not only to the individual features, but also to the combination of the subclaims.

A door sliding front is characterized by a plurality of sliding doors 11 which are arranged displaceably in a running rail 10, the running rail 10 being designed in one (or both) end region in such a way that a plurality of sliding doors 11 which expose an entrance or passage opening are parked there in a space-saving manner and are parked in a confined space can be. For this purpose, at a right angle to the running rail 10, a second running rail 12 adjoins the latter, the rail 10 having a miter-shaped notch 13 for receiving it. The two miter lines meet at a point that lies exactly on an imaginary, longitudinal center line of the running rail 10.

The rail 12 is mitered on both sides of an imaginary, longitudinal center line so that it can be inserted flush into the miter-like notch 13 of the running rail 10. The miter edges lying against each other in this way are preferably connected to one another by welding.

On the horizontal center line of the running rail 10 and the vertical center line of the running rail 12 are formed as guide or switch pins, circular-cylindrical pins 14 in cross section so that their centers lie on said center lines. The intersection of the two center lines forms the center point for a pin 14, to each of which a further pin 14 is arranged at the same distance on both sides on the horizontal center line and at the same distance on the vertical center line.

A third running rail 15 connects to the other end face of the rail 12 facing away from the rail 10. Here, too, the rails 12, 15 are mitred and connected by welding, so that the two rails are at an angle to one another.

The point of intersection of the vertical center line with the center line of the third running rail 15 forms the center point for a pin 14, to which a further pin 14 is arranged at the same distance on the vertical center line and on the center line of the third running rail 15. that their centers lie on the aforementioned center lines. This describes the location of guide or switch pins, as they are attached to rails 12, 15 which are joined together at an angle with a miter, the first description of the position of guide or switch pins being used for a longitudinal rail 10 arranged at an angle on both sides to a rail 12 (see FIG. 4).

The guide or switch pins are characterized by two one-piece pins 14a, 14b of different diameters. After the running rails 10, 12, 15 - as shown in FIG. 4 - have been joined together, bores 17 are made in a web connecting the two halves of a running rail, said bores 17 being located in the center of the web 16. With the pin 14a of smaller diameter, it is inserted through a longitudinal slot opening 18 of the running rail into the bore 17 and thus driven into it until the annular end face 19 of the pin 14b of larger diameter lies on the web surface. The pin 14a of smaller diameter partially protrudes into a running space 20 for guide rollers 21.

The rails assembled according to FIG. 4 can now be screwed by means of screws 22 to a profile carrier 24 embedded in a ceiling 23, wherein according to FIG. 3 the profile carrier 24 has the corresponding threaded bores 25 for the screws 22. The longitudinal slot opening 18 of the running rail serves as a push-through opening for the screws 22.

The guide rollers 21 present in the running space 20 are rotatably supported with their axes vertically by means of a pin 26 in a mounting plate 27, with four rollers each, as can be seen from FIGS. 2 and 3 21 are arranged square above and below the receiving plate 27.

The upper four rollers 21 are just above the lower four rollers 21, i.e. an upper and lower roller 21 is always on one axis.

Furthermore, the rollers 21 are mounted in such a way that two opposing rollers 21 form a passage opening 28 for the pin 14a projecting into the running space 20, the passage opening 28 being slightly larger than the pin diameter.

The receiving plate 27 for the rollers 21 has a central, vertical through bore 29 for inserting a screw 30, the screw 30 being guided through a lower, longitudinal slot opening 31 of the running rail. At the lower end of the screw 30, a rail 34 acting as an adapter and held by two screws 30 is detachably arranged by means of a nut 32 and a lock nut 33.

The rail 34 acting as an adapter is provided in its lower region for releasably receiving a two-part, further rail 35, the two parts of this two-part rail 35 being connected to one another by tightening a screw 36 arranged horizontally in the rail 35, and a glass pane acting as a door 37 or jam the glass plate.

The advantages of the invention are that by inserting switch or guide pins in the miter area of interconnected rails 10, 12, 15 the guide rollers 21 of a suspended sliding door 11 are positively guided in this miter area and thus serve as a switch for the new direction of displacement of the door 11. A kinking or tilting of the guide rollers 21 in this area and thus a time-consuming and cumbersome change of direction of the displacement movement of the door 11, for example into the parking position, is thus avoided (see FIG. 4).

When the guide rollers 21, which are rotatably mounted on and under the receiving plate 27, pass through the miter region of the screw 30, which is inserted through the central through bore 29 of the receiving plate 27, through a miter region of interconnected guide rails with switch or guide pins inserted in this miter region, the pins 14a project smaller Diameter so far into the running space 20 that there is only a small distance between the end face of the pin 14a and the end face of the screw head of the screw 30. A guide of the guide roller 21 which is well adapted to the structural conditions is achieved in this way, since the head height of the upper guide rollers 21 - as far as possible - corresponds to the length of the pin 14a.

The turnout pins 14a form a T-shape with a right-angle turnout or a V-shape with each other at a turnout angle greater or less than 90 °. The drawings are kept on a scale of about 1: 1.5.

The diameter of a switch pin 14a is, for example, 5 mm slightly smaller than the intermediate distance (running space 20) with 5.1 to 5.2 mm between two guide rollers 21.

Another advantage of the invention is that the guide pins with simple shape - two pins 14a and 14b of different diameters, made in one piece and coaxially with each other - can be produced inexpensively and quickly as mass items, so that guide pins in different dimensions for the different sizes (modular systems ) of rails and sliding doors and, if necessary, suitable for the structural conditions on site and can be easily used in a miter area.
