Description

The invention relates to a sliding door system with several sliding doors according to the preamble of patent claims 1 and 4, respectively.

Such sliding door systems, such as those from the WO 93/08355 A1 are used, for example, for the completion of shop fronts of shops, conservatories and balconies. Here are the sliding doors made of glass, which are each included with and without frames and a continuous glass front for completion z. B. the local form. In order to open this glass front, it is known to push the sliding doors to the side, so that they are approximately next to or in front of each other and the entire, previously covered by the glass front opening of the business premises is now free.

For this purpose, however, it is necessary to actuate an associated locking device on each sliding door in order to push this sliding door individually to the side, which is associated with additional handling effort.

It is also known to assign each sliding door a locking or braking device, however, must be operated separately for each sliding door separately.

In the known sliding door system, an automatic sequence when opening the sliding door system takes place such that the next opening side of the sliding door is pivoted from its closed position into an unfolded open position. For this purpose, it is provided that a Ausschwenköffnung is arranged in the running rail through which one side of the sliding door can be swung out with the current there caster roller assembly. This first sliding door is thus pivoted to the side and forms a first opening in the shop front.

In order to also move the other sliding doors into their open position, it is provided that each individual sliding door is moved by hand or with a corresponding electromotive drive (eg a chain or belt drive in the running track) to the location of the first sliding door and then in turn this sliding door with the attached castor wheel assembly is pivoted out of the arranged in the running rail Ausschwenköffnung so that it can be placed as a flat disc on the first swung-out sliding door.

In this way, all the sliding doors are gradually moved to the place of the first, already already pivoted-sliding door and extended by the swung-out described and created as a package on the already swung and preferably arranged perpendicular to the running rail sliding doors.

In this first method step, therefore, a particularly simple opening of the individual sliding doors takes place by swiveling each individual sliding door through a corresponding swiveling opening in the running rail.

With the pivoting of the sliding doors in their open position, a braking device is automatically set at the same time, which locks the swung-out position of the sliding door.

It can therefore be dispensed with known mechanical lock and locking means, because the braking device is installed in the sliding door itself, wherein the braking device is operated with the pivoting movement of the sliding door and locks the pivoting wing relative to the running rail. If the sliding door for closing the glass front is pivoted back into the opposite position, then the braking device is unlocked again and the sliding door is thus freely movable in the running rail.

In the prior art sliding door system, the braking device is formed in a first embodiment by a spring-loaded, cone-shaped pin, which must be brought with its flattened tip in a recess in a bar in the track engaged. It is provided a plurality of juxtaposed recesses in a grid spacing. The problem is that the heavy sliding door must be brought into an exact position to one of the wells, which is naturally difficult,

In a second embodiment of this prior art, the pin is provided with a sharp point which claws into the flank of the running rail for fixing the sliding door. It is obvious that the braking effect is limited by this and should be further affected in the long run by the unavoidable wear of the tip.

The invention is therefore the object of developing a sliding door system according to the preamble of claim 1 so that their braking device can be reliably and permanently activated with high braking effect continuously in any position of a sliding door.

To solve the problem, the invention provides the characterizing features of independent, independent claims 1 and 4, respectively.

In the first embodiment of the invention according to claim 1, the braking device consists of a non-rotatably connected to the main shaft thrust washer, which can be lifted by aushebbare on one above the Thrust washer arranged, spring-loaded brake disc acts, which can be brought into braking engagement with the running rail.

In a second embodiment of the invention according to claim 4, the braking device consists of a rotatably connected to the rotatable main shaft cam pin, which runs with an eccentric cam directly on a slope, which is arranged on the underside of a rotatably mounted cam plate which carries a spring-loaded brake disc, which consequently comes with its brake pad in engagement with the mating surface on the running rail.

Of course, the present invention relates not only to a sliding door system of glass elements. It can all known sliding door elements, such. B. solid wood, veneer, glass or combination elements thereof.

It is important that a simple opening of the covered by the sliding door system opening takes place and that the later to be described in more detail braking device works automatically.

The sliding door system is described below in "hanging" design. The arrangement described can also according to the invention in "standing" design rotated by 180 ° in the lower rail - that is below braking effect - be provided.

In FIG. 1 is schematically illustrated the opening of a sliding door system, wherein, for example, five sliding doors 16 are slidably displayed in a running rail 13 and only three of these sliding doors 16a-c are described in more detail.

On the horizontal, upper side of a building to be closed with the sliding door system opening a guide rail 13 is arranged on the ceiling or a base frame 30, wherein according to FIG. 2 this running rail 13 has at least two planes lying below one another in the horizontal direction.

On the upper level of the running rail 13, a main shaft 1 moves with rollers 10 arranged thereon, this main shaft 1 being associated with the braking device 21 according to the invention.

This upper running rail plane extends over the entire displacement length in the base frame 30.

In the plane of FIG. 2 offset down to the upper rail level connects to a lower rail level, in which a caster roller assembly 25 rolls and which consists essentially of a bearing shaft 15 and rotatably mounted thereon rollers.

Characteristic of this lower running rail level is that in the direction of the pointing in the direction of pivoting front side a Ausschwenköffnung 22 is present, through which this pivot roller assembly 25 can be swung out.

The swinging out takes place about the pivot axis 20 of the main shaft. 1

Incidentally, the running rail 13 also forms a plurality of raceways 35 running vertically below one another and running parallel to one another in the running rail plane.

Each sliding door 16 is thus guided in the direction of arrow 18 and in the opposite direction displaceable in the running rail 13. It is therefore a hanging storage each sliding door, each sliding door, the two shafts 1, 15 are assigned.

Of course, the invention is not limited to the arrangement of two shafts on each sliding door 16. It is also possible to arrange a plurality of shafts parallel to one another, wherein a further shaft arranged parallel thereto can be provided, in particular at a distance from the main shaft 1, but only the main shaft 1 is assigned the braking device 21 according to the invention.

In FIG. 2 the upper running plane in the running rail 13 is designated by the reference numeral 52, while the lower running plane is designated by the reference numeral 53.

The opening process of the sliding door system is now such that the first, right sliding door 16 after FIG. 1 is initially pivoted by the fact that the bearing shaft 15 is already in juxtaposition to the Ausschwenköffnung 22 in the front running plane 53 of the track rail 13. In this way, the first, right sliding door 16 can be easily swung open, thus the situation in FIG. 1 (left picture).

If now more sliding doors are opened, then according to the illustration FIG. 1 (Middle) the next sliding door 16a moved to the previous sliding door 16, so that their bearing shaft 15 comes in juxtaposition to the Ausschwenköffnung 22 and this can also be pivoted in the arrow direction about the pivot axis 20 of the main shaft 1, so as to the first, swung out Sliding door to be unfolded.

In this way, all the sliding doors are gradually winged or erected, so that in FIG. 1 shown right package of collapsed and unfolded sliding doors 16a-c.

It is now important that each of the main shaft 1 of each sliding door is associated with a braking device 21, which occurs after a certain Ausschwenkweg each sliding door in action, thus serves as a pivot bearing for the pivoting movement of the sliding door and folded in the package sliding doors according to the right figure in FIG. 1 securely locked in the raised position.

Therefore, it requires no further locking means, which must be operated separately, because the braking device automatically comes into action with the swinging each sliding door.

The FIG. 3 shows details of the braking device, wherein the items shown there are still shown individually in the later drawing figures.

On the threaded extension 23 of the main shaft 1, a clamping sleeve 12 is screwed, which holds with its front projection 11 the entire structure of the rollers and the braking device together.

The roller assembly consists in the embodiment shown in three levels superposed rollers 10, 10a, all rollers 10, 10a are mounted in plain bearings or axial needle bearings 9 rotatably mounted on the main shaft 1.

The braking device is essentially formed by a rotary coupling 19 which, when the main shaft 1 is rotated about its longitudinal axis, brings the spring-loaded brake disk 3 into engagement with a guide bridge 14 fixedly connected to the running rail 13.

For the formation of the rotary joint, which is able to raise a spring-loaded brake pad in the axial direction, there are various embodiments. It is according to any rotary coupling used, which is able to bring on rotation of a main shaft, a spring-biased brake disc 3 in engagement with a stationary oppositely disposed coating.

In the illustrated embodiment, a driving pin 8 passes through a transverse bore in the main shaft 1 and is in engagement with a thrust washer 7. This is in FIGS. 13 and 14 shown in more detail.

It can be seen that the driving pin 8 is rotatably coupled to the thrust washer 7 in that it engages in a slot-shaped recess 41, which passes through the central bore 42 through which the main shaft 1 passes.

The thrust washer 7 has evenly distributed on the circumference arranged ball seats 45, in each of which a ball 6 engages.

According to FIG. 3 engages each ball 6 in an associated ball seat 33 in a brake carrier 5 a. This brake carrier 5 is in the FIGS. 10 to 12 shown.

In the FIG. 10 it is shown on a smaller scale on the left side, while the right side of the FIG. 10 half of the brake carrier 5 in plan view shows.

At the moment in which the pressure plate 7 is rotated with the main shaft 1 about the pivot axis 20, the balls are lifted out of the ball seats 33 of the brake carrier and push it in the axial direction upwards. The axially upward movement of the brake carrier acts on the disc spring 4 on the underside of the brake disc 3, which thus in the axial direction upward with its brake pad or tuned toothing 31 (FIGS. FIG. 19 ) is brought to the system (braking / stop) on the underside of a guide bridge 14.

The guide bridge 14 is in this case firmly connected to the running rail 13.

Depending on the selected spring rate of the plate spring 4, the brake disc 3 is inserted into the toothing of the guide bridge 14 and clamped there. The brake carrier 5 is secured in this case in the flanks 54 of the guide bridge 14 against rotation.

The balls 6 are embedded in the brake carrier 5 and thus can be used when turning the pressure plate 7, the entire brake package with high braking force.

In order to achieve a good axial guidance, at least two balls of the thrust washer should come into use with the brake carrier 5. When using more than two balls, the distribution should be made so that with left-right pivot insert always at least 98 ° swing of the individual wings is achieved. This can, as in the present Thrust washer 7 arranged to be achieved with different hole circles.

By pivoting back each sliding door in the roll-sliding position of the braking process is reversed, because the balls 6 again get in juxtaposition of the ball seats 33 in the brake carrier 5 and 45 in the pressure plate 7, whereby the brake pack is lifted back from the guide bridge 14.

A corrugated spring / shim 2 in this case supports the return of the brake disc. 3

The vertical load P is introduced in the axial direction from the collar of the main shaft at the top via the bearings 9 on the rollers 10, 10a in the track rail 13.

Overall, for each sliding door 16 so that a main shaft 1 and a swing-out bearing shaft 15, wherein the previously described braking device 21 is disposed at the top of the main shaft 1, which supported at the slightest opening movement of the sliding door in the axial direction by rollers and the disc springs 4th acting continuously on a suitable braking surface or toothing on the guide bridge 14, the sliding door holds during pivoting.

The FIG. 4 shows that the superimposed and mounted in needle or plain bearings 9 rollers 10 are rotatably mounted on the swing-out bearing shaft 15, which reach into a so-called Schmiegungseingriff with the associated running surfaces of the rail 13. This particular procedure is based on the FIG. 24 explained later.

The FIG. 5 shows a section through the aforementioned clamping sleeve 12 without the approach 11th

The FIG. 6 shows one opposite FIG. 3 upside down half-section through the main shaft 1, where it can be seen that on the threaded extension 23, the clamping sleeve 12 after FIG. 5 is screwed on. The roller assembly is mounted on the cylindrical shaft 24. Likewise, the transverse bore 26 is shown, through which the in FIG. 3 shown driving pin 8 passes through. At the top of a receptacle 28 is still shown.

The braking device 21 is arranged in the region of the cylindrical shaft 27.

The FIGS. 7 to 9 show the previously mentioned disc 3, at the top of a toothing 31 is arranged, which comes in braking engagement with the underside of the guide bridge 14.

For reasons of weight saving there recesses 29 are arranged at the bottom.

The assignment of brake carrier 5 to the brake disc 3 and the guide rail 14 fixedly connected to the running rail 13 is in FIG. 19 shown in more detail.

In the in the FIGS. 10 to 12 illustrated brake carrier 5 is essentially a square plate in the bottom four spaced apart and upwardly open ball seats 33 are arranged for receiving the balls 6.

Each ball 6 is held by a few Hunderstel mm more in the upper part of the brake carrier, as compared in the associated ball seat 45 in the pressure plate 7th

This is indicated by the schematic drawing in FIG. 12 where it can be seen that the ball seats 33 allow axial play of each ball 6, but at the same time prevents a slight Lippenumschlingung that the balls 6 only slip down on the thrust washer 7.

When the thrust washer 7 is rotated over the main shaft 1, balls 6 are dug out of the bores of the thrust washer 7 and thus cause the axial stroke of the brake carrier 5, which acts on the spring 4, the brake disc 3 upwards and the arrangement thus in the axial direction in the running rail 13 is locked with a corresponding stop operation (brake or toothing).

Of course, other drive devices can be used instead of the ball lift described here. In particular, it is possible to arrange on the upper side of the thrust washer 7 so-called wedge or bevel slopes, which cooperate with associated bevels on the underside of the brake carrier 5 so as to allow an axial lifting movement of the brake carrier 5 during the rotation of the thrust washer 7.

As already mentioned before, that is in the FIGS. 13 and 14 shown thrust washer 7 rotatably coupled to the main shaft 1, that the main shaft 1 passes through driving pin 8 engages in the elongated recess 41 of the pressure plate 7 and this entrains in a rotation of the main shaft 1.

The FIG. 15 shows the execution of an upper roller 10a, which is made smaller in size proportions compared to the rollers 10 for space saving reasons and consequently also has a reduced in size recess 44 for weight saving.

It has a comb, the top of which carries a slope 43.

Should run of the running rail 13 condensation on the vertically below one another arranged rollers 10a, 10, then this is discharged from the respective slopes 43 to the outside and does not reach the area of the associated bearing. 9

The opposite show the FIGS. 16 and 17 a roller 10, as used in the lower levels of the track rail 13.

The FIG. 18 shows the profile of a running rail, which essentially forms a U-shaped box profile. There are here, for example, three underlying raceways 35, wherein an upper profile section is completed by a central web 46, in which the guide bridge 14 is anchored.

The anchoring of the guide bridge after FIG. 19 takes place in that the dowel-like locking projections 34 at the top of the guide bridge 14 in associated recesses 55 in the region of the central web 46 of the Track 13 engage and anchored there, doweled or screwed.

The FIGS. 20 to 22 show more details of the guide bridge. It is essentially a U-shaped profiled part, on the underside of a toothing 56 is arranged, which comes into meshing engagement with the toothing 31 of the brake disc 3.

The FIG. 19 shows that the brake disc 3 and the brake carrier each have central bores 40, 32, through which the main shaft 1 passes through.

The FIG. 23 shows a half-section and a half-plan view of the swing-out bearing shaft 15, which in section along with roller assembly in FIG. 4 was shown.

In the respective drawings is the detail X. This is based on the FIG. 24 explained in more detail.

Each roller 10, 10a has a profile on the track 35 of the track 13 approximately rounded profile, which, however, only between the positions 37, 38 enters a so-called osculation with the track 35 of the track rail 13.

The load transmission takes place in this Schmiegungsbereich 36th

This has the advantage that at large thermal expansions enough clearance for an expansion of the roller 10, 10a on the Runway 35 and this is always a high load-transmitting area on the track 35 is available.

As a result, not only a point or line contact is present in the present osculation, but a surface support that reduces / reduces the specific surface pressure.

The FIGS. 25 to 30 show a further embodiment of a braking device 39. According to FIG. 25 the braking device 39 consists of a again a bore in the main shaft passing through the cam pin 47, which lifts the cam disc 49 on the link opening 51 for braking. According to FIGS. 29 and 30 the cam pin is formed approximately semicircular and has a comb-like, axially extending cam 48.

The cam pin passes through the gate opening 51 in the cam plate 49 in accordance FIG. 28 , The underside of the cam plate 49 has a slope 50, which runs directly on the cam pin.

With the rotation of the cam pin 47 with the main shaft 1 about the axis of rotation 20, the disc spring 4 is thus pressed directly against the brake disc 3 and their teeth now passes directly into meshing engagement with the rail 13. It thus also eliminates a previously described guide bridge 14th

The FIG. 26 shows a half section through the previously already mentioned bearing shaft 15 together with the roller arrangement.

Overall, results with the sliding door system shown the significant advantage that high loads (that is, large glass sliding doors) can be controlled at large temperature changes and also when exposed to moisture. By automatically with the pivoting of each sliding door in motion to be set braking device 21, 39, it is possible to set the sliding doors in their swung-out position without further manual intervention.
