Abstract

The carriage has a running roller (15) rolling on a running rail (13) for supporting the object (1) and a counter rail (25) on which a counter roller (27) rolls, whereby the running and counter rollers have an associated rocker-shaped running mechanism bearer. The wt. of the object bears at least partly on an engagement point on the bearer offset wrt. the roller axis. The counter roller axis is arranged on the opposite side of the running roller axis from the engagement point. The load wt. forces the counter roller onto the counter rail. An Independent claim is also included for a sliding door or gate.

Description

The invention relates to a carriage for a movable Subject, especially for an automatic Sliding door or an automatic sliding gate after the Preamble of claim 1 and an associated sliding door or a sliding gate according to claim 14.

A track arrangement for an automatic sliding door with at least one wing is from DE 44 00 940 C1 became known. It is a cross section essentially angular running rail, which as Profile carrier is formed and on their vertical profile wall section lying down on one essentially transversely projecting track support section one in cross section spherical track is formed. The previously known Track arrangement also has on its upper, essentially horizontally protruding profile carrier legs a correspondingly curved in opposite directions another track section on which one in the Height to the other castors further shifted up unrolled securing roller rolls.

To ensure good storage of the sliding door leaves to be moved or the like will usually be Drives used, for example on a sliding door leaf at its leading and trailing end, i.e. in essentially adjacent to the corner areas of the door leaf are provided overhead. Each drive includes usually at least one, preferably two in the longitudinal direction of the door leaf offset casters, the roll on a track below and do that absorb the proportional weight of the sliding door leaf. To at Accelerate or brake the door leaf and in particular when the sliding door wing hits an obstacle resulting tilting moments are better absorbed the above mentioned on an overhead and with the Tread downward running safety rail Counter rollers are provided, usually per rope a counter roller is provided.

It is a disadvantage of this roller arrangement that this Counter-rollers absorbing tilting moments and serving as security during assembly individually on a backlash-free Run must be set. There is the Danger that the counter rollers are either tightened too tight be causing jamming of the drive and therefore too would lead to a difficult run or that with a Setting a game that is too large continues to pose a risk there is that the door wing at high accelerations or can tilt delays by a small amount. However, this would have increased wear on the barrel and Counter rolls and also an unpleasant noise result.

Furthermore, it turns out to be disadvantageous in part State of the art that the exact adjustment of the Door leaf and the exact edge alignment at least simple way can not be made or at least an adjusting device increasing the overall height require.

The object of the present invention is therefore a improved carriage arrangement compared to the prior art as well as an improved sliding door or an improved one To create sliding gate to ensure that such a carriage is simple and optimal under Avoiding an unwanted game but avoiding it jamming along a rail is movable.

The object is achieved with respect to the carriage arrangement corresponding to that in claim 1 and with respect to Sliding door or the sliding gate according to the claim 14 specified features solved. Advantageous configurations of the invention are in the subclaims specified.

The present invention makes it amazingly simple Way compared to conventional carriage arrangements, i.e. Drives, especially for sliding door leaves achieved a significant improvement.

The main advantage according to the solution according to the invention According to claim 1 it can be seen that one to one Drive belonging roller and a counter roller a rocker arm. By attacking the carriage The rocker arm can pivot around the weight Axis of the roller rolling on the lower track at least in a certain angular range make sure that the one that is offset from the roller Counter roller pivoted upwards over the rocker arm until the tread is in contact with the counter rail. This will result in constant automatic self-adjustment guaranteed, always a continuous system pressure guaranteed between the counter roller and the counter rail is. It also eliminates a time consuming and incorrect adjustment of the counter roller away.

In addition, according to claim 2, an eccentric arrangement provided, the eccentric axis parallel to the roller axis lies. By turning this eccentric arrangement the associated roller axis at different heights adjusted. The vertical adjustment that can be achieved in this way the relative height between the roller or roller axis and the item carried over the drive, preferably a door leaf, so it does not take place an adjustment mechanism running in the vertical direction, but over a horizontal axis Eccentric arrangement, resulting in an overall very low Height of the drive can be achieved, especially since the upper, a movable sliding door leaf supporting profile thus preferably directly from the eccentric arrangement is penetrated and thus laterally by the roller can sit.

It also proves to be advantageous that according to one Development of the invention of an independent adjustment the counter role to the counter rail Rocker arm immediately to the side of the upper one door wing supporting end profile can be arranged, so that even when using this independent adjustment mechanism a low overall height is realized.

It has also proven to be cheap that with simple Averaging the top end profile, i.e. preferred to the side opposite to the rollers, peripheral parts can be grown, such as a Carrier for a toothed belt or a support plate with Locking bolt to lock one or the other possibly two interacting sliding door leaves.

The invention is explained in more detail below with reference to drawings. The individual shows:

In Figure 1 is a schematic perspective view a two-leaf sliding door arrangement with two in opposite directions movable sliding door leaves 1 and two themselves fixed side panels connected to the outside 3 shown. This sliding door arrangement is common arranged in a passage in a wall 5, each sliding door leaf 1 via a carriage arrangement is carried and moved along a rail. The Entire track arrangement, the drive and the control device etc. are usually in one above of the sliding door leaf 1 arranged horizontally extending elongated housing 7 housed.

In Figure 2 is a schematic vertical sectional view transversely to the sliding door leaf 1 can be seen that in the housing 7, which can be designed as a profile carrier, on a horizontally aligned in the embodiment shown Support web 11 preferred in cross section slightly spherical or convex curved track 13 is provided is, on each of which a roller 15 one Carriage arrangement, hereinafter also referred to as a carriage, with a correspondingly concave cross section Tread 19 expires.

Above the respective roller 15 is one of the fuse serving counter rail 23 on the housing or profile carrier 7 arranged on which one to the first roller 15th counter roller 27 runs higher, its tread 29 again on the profile surface 25 of the counter rail 23 is adapted.

As can be seen from Figure 2, is to the side respective roller 15 and counter roller 27 the upper End profile 31 of the movable sliding door leaf 1 provided, resulting in a small overall dimension the horizontal and vertical dimensions of the Allow housing 7 to achieve. The final profile 31 is via a driver 69 either with the lower flange 67 or the upper chord 68 of a driven by a drive device Belt in connection, over which the wing move becomes.

In the following, reference is made in particular to FIGS. 3 ff. to further structure the drive in detail describe.

The actual carriage arrangement, i.e. the real thing adjacent to the upper corner areas of a sliding door leaf 1 arranged drive, includes in the embodiment shown one each on a lower rail 21 rolling roller 15 and the counter roller 27, the one above it parallel to the first rail extending counter rail 23 rolls. The roller 15 rotates on or with a roller body 37 about a roller axis 37 'and the counter roller 27 turns on or with a counter roller axle body 39 about the counter roller axis 39 ', in the exemplary embodiment shown on a plate-shaped carrying the roller and the counter roller Drive carrier 41 are supported. These are in the drive carrier 41 two bores 37 '' and 39 '' made in which the roller axis 37 'or counter roller axis 39' the running or counter roll axle body 37 or 39 anchored and assembled.

The over this drive carrier 41 and the running and counter roller (as well as at least one more in the figure drive carrier, not shown, but constructed in the same way 41) worn door leaf 1 is with its upper end profile 31 not fixed, but tiltable on the drive carrier 41 attached. To this extent, the drive carrier 41 represents a seesaw support or a seesaw around a horizontal and transverse to the door leaf level and coinciding with the axis 37 'of the roller 15 Tilt axis 43 with respect to the end profile 31 and thus the Door leaf 1 is pivotable.

The tilt axis 43 intersects the seesaw-shaped drive carrier 41 at tipping point 46a. The counter roller axis 39 intersects the rocker-shaped drive carrier 41 in the by the Hole 39 'formed point of attack 46b. On the opposite Side to the roller 15 is the rocker-shaped Finally, drive carrier 41 by means of a screw 51 screwed to the upper end profile 31, the Screw body 51 in a bore 45 in the drive carrier 41 engages. The screw body 51 penetrates one Eccentric 53, the one in the end profile 31 horizontally and bore 55 penetrating transversely to the plane of the door leaf sits. The eccentric 53 is in the bore 55 in the end profile 31 held radially immovable, can however, be rotated about its axis, causing the internal eccentric bore 57, which from the screw 51 is enforced, in its relative altitude slightly can be changed.

Since the bore 45 in the rocker-shaped drive carrier 41 as Threaded hole is formed and the end of the screw 51 engages in this threaded hole, is the above rocker-shaped drive carrier 41 can be pivoted about the screw 51 held on the end profile 31 and secured.

A support point 46c is formed through the bore 45, on which finally the proportional weight of the door leaf 1 starts, the three support points 46c, 46a and 46b in this order preferably at least approximately lie in a straight line, but do not have to lie. The Indian The center support point 46a forms the tilt or Seesaw axis.

The mode of operation can also be found directly under Taking into account Figure 4 and 5. The weight of an over the closing profile 31 held door leaf 1 acts over the eccentric 53 and the one passing through the eccentric 53 Screw 51 on the rocker-shaped, like a lever designed drive carrier 41, the roller 15 on the running rail 21 rests. Because that through the screw axially extending axis of attack 51 'to the roller axis 37 'is offset, in other words on the Support point 46a the door weight G (proportionately) attacks and the position of the roller axis 37 'through the on the track 21 resting roller 15 in their Altitude, this causes the rocker-shaped Drive carrier 41 according to the roller axis 37 Arrow K tilts and that to the roller or attack axis 37 opposite counter-roller axis 39 pivoted upwards until its roller surface 29 on the counter-tread 25 of the counter rail 23 abuts.

In other words, the weight of the door leaf an independent rotation of the lever around its roller or Tilt axis 37 and a constant concern of the counter roller 27 effected on the counter rail 23.

The contact pressure P ² with which the counter roller is pressed against the counter rail is determined by the lever ratios, ie by the ratio of the distance between the support point 46c and the support point 46a formed by the roller or tilt axis 37 'to the distance between this support point 46a and the support point 46b of the counter roller axis 39 '. In addition, the contact pressure is naturally influenced by the weight of the object to be carried over it, in the exemplary embodiment of the door leaf shown (usually two drive arrangements shown in the drawings are arranged on the two upper leading and trailing corner areas of a door leaf and thus on each carriage the Half of the door leaf weight attacks). A force ratio of 5: 1 is typically realized between the contact pressure P1 of the roller 15 and the counter pressure P ^{2 of} the counter roller 27.

The hanging of such a door leaf is also extreme simple. When hanging a door leaf 1, the door leaf raised and then lowered so slightly that the Roller 15 rests on the rail 21, the further lowering by the door weight the lever and seesaw-shaped drive carrier 41 around its rollers and Tilt axis 37 rotates slightly until the counter roller 27 on the abutting rail 23 abuts. Further Adjustment measures are no longer necessary.

By rotating the eccentric arrangement 53 about its longitudinal axis and the slight relative change in altitude caused thereby related to the drive carrier 41 Above all, the door edges can quickly and exactly parallel aligned with each other.

For some reason, the pressing and tilting mechanism can be overridden, a fixing screw 61 through a penetrating the upper end profile 31 inserted further hole 63 and into a introduced in the plate or lever-shaped drive carrier 41 further threaded bore 65 are screwed in, whereby the tilt mechanism is locked.

For the sake of completeness it is mentioned that more Peripheral parts, such as a driver 69, by means of nuts 70 on a driver plate 71 and this again by means of screws 73 and in longitudinal grooves 75 in End profile 31 laterally insertable threaded stones 77 am End profile fixed at the appropriate place can be.

Furthermore, a locking bolt 81 can also have Locking plate 83 in the same way on the end profile 31 are mounted, on which the Sliding door assembly engage a locking hook and the two door panels against each other against an unintended Can tightly lock and lock opening.

However, the end profile 31 does not necessarily have to be on the side provided sitting next to the rollers and counter rollers his. Rather, the rocker-shaped drive carrier 41 with the same adjustment mechanism on one in Longitudinal direction of the door leaf concerned Bracket attached, which is like a corresponding bracket in of the previously published EP 0 770 752 A1 the disclosure content of which is referred to in full and made the content of this application). At this The rocker-shaped drive carrier 41 is then the bracket same adjustment mechanism as explained above, appropriate. The bracket can with its lower anchoring section to below the level of the lower track 13 and thus down the rollers and there on the Top edge area of a door leaf to be moved, in the As a rule, an attached end profile attached his. The drive drive, i.e. the housing arrangement, in this case claims a slightly larger vertical Height, whereby the horizontal dimensions are smaller can be designed.

Finally, drive designs are also known, which, for example, two parallel to each other include lateral rails that are spaced from one another, as for example in Figure 13 of the prior publication WO 98/29629 are shown. In between is the drive body arranged, for example at its lower end the door leaf to be moved can be hung. But it can also be a U-shaped drive body are used, the open side of which projects downwards to anchor the door leaf to be moved here. Here too Counter rollers can be provided, each using one the rocker-shaped drive carrier explained in Figures 1 to 5 41 then left and right on the drive body or the U-shaped profile beam with the same Mode of action can be appropriate.

The exemplary embodiments are explained for that case been that the mating track above the actual Track 13 is arranged. But it can do the same Mating track also below the track 13 and / or be arranged with a lateral offset. In this Trap only the counter roller 27 must be correspondingly lower compared to the actual roller 15 on a suitable designed drive carrier sit.
