Description

The invention relates to a carriage for a method ed item, especially for an automatic Sliding door or an automatic sliding gate after the Preamble of claim 1 and an associated shooting 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 known. It is a cross cut essentially angular track, which as Profile carrier is formed and at their vertical pro filwandabschnitt lying at one essentially transversely protruding track support section one in the transverse  cut crowned track is formed. The past known track arrangement also has on its upper, essentially horizontally protruding profile carrier a correspondingly curved in the opposite direction 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 wing 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 length In the direction of the door leaf, the casters are offset 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 Blue tread of safety rail pointing downwards fende counter roles provided, usually per Lau counter roll is provided.

It is a disadvantage of this roller arrangement that this Ge absorbing overturning moments and securing Gene roles individually during assembly at a game must be set free run. 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 least an adjustment device increasing the overall height require.

The object of the present invention is therefore a Carriages improved compared to the prior art arrangement and an improved sliding door or a ver to create better sliding gate to ensure that such a carriage is simple and optimal under Avoiding an unwanted game, however, avoiding it a jamming along a rail is movable.

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

The present invention is astounding simple way compared to a conventional carriage arrangement solutions, d. H. 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 le 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 investment Ensure pressure between the counter roller and the counter rail is accomplished. 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 corresponding roller axle at different heights height adjusted. The vertical adjustment that can be achieved in this way the relative height between the roller or roller axis and the object carried over the drive, preferably  wise a door wing, so it does not take place a vertical adjustment mechanism mus, but over a horizontal axis Eccentric arrangement, which makes an overall very low height of the drive can be achieved, especially since the upper, a movable sliding door leaf-carrying closure Profil thus preferred directly from the eccentric 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 adaptation solution of the counter role to the counter rail Rocker arm immediately to the side of the upper one door wing-bearing end profile can be arranged, so that even when using this independent setting mechanism a low overall height is realized.

It has also proven to be cheap that with simple Averaging the top end profile, d. H. preferred to the side opposite the rollers, Periphe Rail parts can be attached, 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 described below with reference to drawings explained in more detail. The individual shows:

FIG. 2 is a schematic vertical cross-section transverse to the rail;

Fig. 3: an exploded view of a drive according to the Invention;

Fig. 4: a partial perspective Dar position of the drive when installed on a door wing state; and

Fig. 5: a corresponding perspective, to Fig. 4 rear view of the inventive drive.

In Fig. 1 is a schematic perspective view of a two-leaf sliding door assembly with two against sensible sliding door leaves 1 and two adjoining outwardly fixed Be tentteile 3 is shown. This sliding door arrangement is usually arranged in a passage in a wall 5 , each sliding door leaf 1 being carried over a carriage arrangement and being moved along a rail. The entire track arrangement, the drive and the control device etc. are usually arranged in a arranged above the sliding door leaf 1 horizontally extending the elongated housing 7 .

In Fig. 2 is a schematic vertical sectional view transversely of the sliding door leaf 1 can be seen that in the Ge housing 7, which may be designed as a profile carrier, at a in the embodiment shown horizontally directed carrying web 11 is a cross-section preferably slightly convex or convex-curved running rail 13 in front is seen, on each of which a roller 15 of a carriage arrangement, hereinafter also called drive ge, with a correspondingly concavely curved tread 19 runs.

Above the respective roller 15 is a hedging serving counter rail 23 is arranged on the housing or profile support 7 , on which a higher to the first roller 15 counter roller 27 runs, the tread 29 is again adapted to the profile surface 25 of the counter rail 23 .

As can be seen from Fig. 2, the upper end profile 31 of the movable sliding door leaf 1 is provided laterally to the respective roller 15 and counter roller 27 , whereby overall a small dimensioning of the horizontal and vertical dimensions of the housing 7 can be achieved. The end profile 31 is connected via a driver 69 with either the lower flange 67 or the upper flange 68 of a belt driven by a drive device, over which the wing will travel ver.

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

The actual carriage arrangement, ie the actual adjacent to the upper corner areas of a sliding door leaf 1 drive, comprises in the exemplary embodiment shown, each from a rolling on a lower rail 21 roller 15 and the counter roller 27 , which is located on an overlying parallel to the first rail counter rail 23 rolls. The roller 15 rotates on or with a roller body 37 around a running roller axis 37 'and the counter roller 27 rotates on or with a counter roller axle 39 around the counter roller axis 39 ', which in the exemplary embodiment shown is supported on a plat-shaped drive roller 41 supporting the counter roller and the counter roller are. For this purpose, two holes 37 '' and 39 '' are made in the drive carrier 41 , in which the roller axis 37 'or counter roller axis 39 ' of the roller or counter roller axle body 37 or 39 are anchored and mounted ver.

The door leaf 1 supported on this drive carrier 41 and the running and Ge genrolle (as well as a at least another not shown in the figure, but just as constructed drive carrier 41) with its upper end profile 31 is not fixed but tiltably on the drive relevant authority 41 attached. The drive carrier 41 is so far a rocker carrier or a rocker, which or which run around a horizontal and transverse to the door leaf plane de and with the axis 37 'of the roller 15 coincident tilt axis 43 relative to the end profile 31 and thus the door leaf 1 is pivotable.

The tilt axis 43 intersects the rocker-shaped drive carrier 41 at the tilt point 46 a. The counter-roller axis 39 cuts the rocker-shaped drive carrier 41 in the point of attack 46 b formed by the bore 39 '. On the opposite side to the roller 15 , the rocker-shaped drive carrier 41 is finally screwed to the upper end profile 31 by means of a screw 51 , the screw body 51 engaging in a bore 45 in the drive carrier 41 . The screw body 51 passes through an eccentric 53 which is seated in a bore 55 which passes through the end profile 31 horizontally and transversely to the plane of the door leaf. The eccentric 53 is in the bore 55 in the closing profile 31 from radially immovable, but can be rotated about its axis, whereby the inner eccentric bore 57 , which is penetrated by the screw 51 , can be changed slightly in its relative altitude.

Since the bore 45 is formed in the rocker-shaped drive carrier 41 as a threaded bore and the end of the screw 51 engages in this threaded bore, the rocker-shaped drive carrier 41 is pivotally held and secured on the end profile 31 by the screw 51 .

Through the bore 45 , a support point 46 c is formed, at which finally the proportionate weight of the door wing 1 attaches, the three support points 46 c, 46 a and 46 b in this order preferably being at least approximately on a straight line, but not lying have to. The support point 46 a in the middle forms the tilting or rocking axis.

The operation follows immediately also considering Figs. 4 and 5. The weight of a door panel 1 held on the end profile 31 acts on the eccentric 53 and the cam 53 passes through screw 51 designed on the rocker-like, by way of a lever drive carrier 41, wherein the roller 15 rests on the rail 21 . Since the axially passing therethrough by the screw attack axis 51 'axially to the running rolls 37' offset is, (proportionately) engages in other words at the supporting point 46 a the door weight G and the position of the roller axis 37 'by resting on the running rail 21 roller 15 is fixed in its height, this leads to the fact that the wippenför shaped drive carrier 41 tilts about the roller axis 37 according to arrow K and the opposite to the roller or attack axis 37 opposite roller axis 39 is pivoted up until its roller surface 29 on the counter-running surface 25 of the counter rail 23 abuts.

In other words, the door leaf weight thus causes the lever to rotate independently about its roller or tilt axis 37 and the counter roller 27 to bear against the counter rail 23 .

The contact pressure P ² , with which the counter roller is pressed against the counter rail, is by the lever ratios, ie by the ratio of the distance between the support point 46 c and the axis formed by the roller or tilt axis 37 'to the support point 46 a Distance between this support point 46 a and the support point 46 b of the counter roller axis 39 'determined. In addition, the contact pressure is naturally influenced by the weight of the object to be carried, 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 attacks half of the door leaf weight). Typically, a force ratio of 5: 1 between the contact pressure P1 of the roller 15 and the counter pressure P ^{2 of} the counter roller 27 is realized.

The hanging of such a door leaf is extremely easy. When hanging a door leaf 1 , the door leaf is raised and then lowered so slightly that the roller 15 rests on the running rail 21 , the lever and rocker-shaped drive carrier 41 rotating slightly about its roller and tilt axis 37 when the door weight is lowered further until the counter roller 27 abuts the counter rail 23 located above it. No further adjustment measures are necessary.

By rotating the eccentric arrangement 53 about its longitudinal axis and the resulting slight relative height change in relation to the drive carrier 41 , the door edges in particular can be aligned quickly and exactly parallel to one another.

Should for some reason the contact and Kippmecha mechanism be overridden, a fixing screw 61 can be inserted through an upper end profile 31 through setting further bore 63 and inserted into a plate or lever-shaped drive carrier 41 inserted further threaded bore 65 where is locked by the tilt mechanism.

For the sake of completeness, it is also mentioned that further peripheral parts, such as a driver 69 , by means of nuts 70 on a driver plate 71, and these in turn by means of screws 73 and in longitudinal grooves 75 in the end profile 31, threaded stones 77 which can be inserted laterally on the end profile at the appropriate place .

Furthermore, a locking bolt 81 having locking plate 83 can be mounted in the same way on the end profile 31 , which can engage a locking hook in the assembled state of the sliding door arrangement and can firmly lock and lock the two door leaves against one another against unintended opening.

However, the end profile 31 does not necessarily have to be seated on the side next to the rollers and counter rollers. Rather, the rocker-shaped drive carrier 41 with the same adjustment mechanism can also be attached to a bracket running in the longitudinal direction of the door leaf in question, which is designed like a corresponding bracket in the previously published EP 0 770 752 A1 (to whose disclosure content is referred to in full and the content thereof Registration is made). The rocker-shaped drive carrier 41 with the same adjustment mechanism as explained above is then attached to this bracket. The bracket can with its lower anchoring section up to below the level of the lower slide ne 13 and thus the rollers roll down and there at the upper edge region of a door leaf to be moved, usually a fastening profile attached there. The drive mechanism, ie the housing arrangement, in this case requires a somewhat larger vertical height, whereby the horizontal dimensions can be made smaller.

Finally, however, also drive constructions are known, which include, for example, two parallel running rails spaced from each other, as shown for example in Fig. 13 of the previous publication WO 98/29629. In between, the running gear body is arranged, at its lower end, for example, the door leaf to be moved can be hung. In this respect, however, a U-shaped drive body can also be used, the open side of which projects downwards in order to anchor the door leaf to be moved here. Again, counter-rollers can be provided, each with a rocker-shaped running gear carrier 41 explained with reference to FIGS . 1 to 5 lying on the left and right lying on the running gear body or the U-shaped profile carrier with the same mode of action.

The exemplary embodiments have been explained for the case that the mating track is arranged above the actual track 13 . In exactly the same way, the mating track can also be arranged below the track 13 and / or with a lateral offset to it. In this case, only the counter roller 27 has to sit correspondingly lower than the actual roller 15 on a suitably designed drive carrier.
