Description

One door drive device Sliding and assembly procedure.

The invention relates to a device of drive for a sliding door and a procedure for its assembly

The drive devices for doors Slides generally comprise a drive unit housed stationary on a baseboard or foundation, which presents an engine housed in a housing of the unit drive, which drives a cogwheel. The unit of drive is within walking distance of sliding door, which is arranged movable in its longitudinal direction. For move the sliding door in a predetermined direction, it is fixed on it a zipper, which extends in the direction Longitudinal sliding door and gear with cogwheel (see, for example, FR-A-2853683).

A problem in systems of this type consists in the mounting of the drive device ,. Especially the Zipper mounting on the sliding door is attached with considerable difficulties. The zipper must be fixed in this case at the sliding door so that it is in a height-defined position on the sliding door, so that The rack meshes with the cogwheel teeth. The Zipper length typically extends over several meters Over this length the zipper must be mounted exactly in the default height position. To get this, from according to the known assembly procedures, the rack from above on the sprocket in the unit drive The cogwheel is disengaged from the engine during the assembly and can be rotated in this way freely. In a Zipper's first resting position is fixed in the area of the cogwheel the rack by means of a first housing in A first fixing point. Then the door moves sliding, so that the guided rack on the wheel is dragged toothed In a second resting position the zipper is fixed this through other accommodation in the sliding door, so that the resting position is selected so that this Accommodation is located in the cogwheel area.

In this procedure it is an inconvenience that the rack guide does not provide any sprockets defined reference point for mounting the rack on a height position defined on the sliding door. This is based on that the rack's height position depends on the position Current of cogwheel teeth. Oscillations conditioned by the zipper height positions  They are typically in the range of 1 mm to 2 mm. Because these oscillations, the height position of the zipper, in the that it is fixed on the sliding door, suffers from inaccuracies corresponding. This leads during the operation of the sliding door to an unstable march during the movement of opening or closing the sliding door.

Another drawback of this procedure it consists in that for the forecast of the reference points of the Zipper mounting on the sliding door, the rack on the cogwheel, so that the Zipper without play on the teeth of the cogwheel. If the zipper is mounted on these landmarks in the door sliding, the zipper is guided during the operation of the sliding door in a corresponding manner without play in the cogwheel. However, by virtue of the performance of the force between the rack and the cogwheel leads to high wear of these components.

The invention has the task of preparing a drive device for a sliding door, which You can ride exactly with the least possible expense.

For the solution of this task, they are The characteristics of claims 1 and 14 are provided. advantageous embodiments and convenient developments of The invention is described in the dependent claims.

The drive device according to the invention for a sliding door has a unit of drive housed stationary with a motor and a wheel serrated as well as a zipper fixed in an objective position in The sliding door. For the activation of the sliding door, the cogwheel is housed in a working position, in which the Cogwheel gears with the zipper. For mounting the Sliding door zipper, cogwheel and can position in an adjustment position that is below The work position. In the adjustment position, a spacer is settles at least on a partial section of the teeth of the cogwheel, so that the outer side of the spacer It forms a sliding surface for the zipper and features a distance from the center of the cogwheel, which is adapted to the difference in the position of the cogwheel in the working position and in the adjustment position. For the adjustment of the objective position of the zipper, this is on the sliding surface of the spacer.

With the spacer according to the invention a defined reference surface is created for the support of the zipper, which allows an exact and reproducible application of the zipper on the sliding door and therefore a mount precise of the drive device for the sliding door. So that the outer side of the spacer, which forms the surface reference, set the height position exactly to the zipper that is placed there for fixing on the door Sliding, the wheel is positioned for mounting serrated from a work position in an adjustment position. In In this case, the dimension of the spacer is adapted to this position difference

In this way an alignment and fastening the door as accurately as possible sliding. In particular, through adequate sizing of the spacer you can predetermine the height position of the zipper to fix on the sliding door, so that during the operation following the door assembly process Sliding the zipper is guided with a predetermined set in the cogwheel teeth. This way a march is guaranteed Silent sliding door, also preventing wear of the components of the drive device.

In this case, it is essential that the position objective, on which the zipper must be mounted on the door sliding, can be predetermined in a defined way simply through the dimensioning of the spacer and through of the difference in position between the work position and the adjustment position

The drive unit presents in this case preferably a rotating mechanism, by means of which You can turn the sprocket optionally to the brought position and to the adjustment position. The rotating mechanism can be activated easily and also guarantees an exact adjustment of the cogwheel in the working position or in the adjustment position.

With the spacer according to the invention the drive device is mounted on the following stages of the procedure:

accommodation stationary of a drive unit with a motor and a wheel toothed operated by it,

Positioning of the cogwheel in an adjustment position, which is around a predetermined position difference below of a cogwheel working position,

Application of a spacer over at least a partial section of the teeth of the cogwheel, so that the outer side of the spacer has a distance from the center of the cogwheel, adapted to the position difference,

Adjustment of target positions of a sliding door zipper to through the application of the zipper on the outer side of the spacer, which forms a sliding surface for the zipper,

Fixing the zipper in the target positions on the door sliding,

Disassembly of spacer outside the cogwheel,

Introduction of the cogwheel in the working position, in which the wheel Toothed gear with the zipper.

Through the dimensioning according to the invention of the spacer ensures that the sprocket runs after positioning in your work position without other processes of adjustment or adaptation with a set defined in the zipper.

In an embodiment especially advantageous of the invention, the spacer is configured as mounting ring Depending on the mounting ring is configured of one or several parts, this can be coupled or folded over the cogwheel.

An essential advantage is that the ring assembly that sits on the cogwheel has a side external symmetrical rotary with respect to the center of the wheel toothed This outer side therefore forms in a way. independent of the rotating position of the cogwheel a support surface that is at a constant height for the zipper.

The side is used to mount the zipper. outside of the mounting ring as a sliding surface for the zipper During the assembly process, the sliding door in such a way that the zipper rests with Different segments on the mounting ring. In these positions, the zipper is fixed with the help of fixing, which are positioned in housings in the zipper, locally at the sliding door. In an advantageous way, it slides the zipper over the ring assembly in such a way that the respective housing is in the area of the mounting ring, since there the zipper is exactly in your objective position. The assembly process configured in this way can also be done in a way Quick and easy by unskilled personnel.

The invention is explained below with the Help of the drawings. In this case:

Figure 1 shows a representation schematic of a sliding door, which can be activated by of a drive device.

Figure 2 shows a partial representation of the drive device according to figure 1 with a rack that gears on a cogwheel when the cogwheel It is placed in a working position.

Figure 3 shows a partial representation of the drive device according to figure 1 with a motor rotatably housed to drive the sprocket according to figure 2.

Figure 4 shows a representation of the cogwheel according to figure 2 in an adjustment position with mounting ring placed on top and with the zipper placed on East.

Figure 5 shows a representation of the cogwheel according to figure 4 in the adjustment position with the disassembled mounting ring.

Figure 1 schematically shows a door sliding 1, by means of which an opening of door in a wall 2. For opening and closing, respectively, of the door opening moves the sliding door 1 in its longitudinal direction For driving the sliding door 1 guides not shown separately can be provided.

For the realization of movements of sliding door sliding 1, to this door is associated  A drive device, This drive device it comprises a drive unit 3, which is fixed on a plinth 4 anchored on the side of the ground and thus forms a stationary unit Figure 1 shows the housing 5, in which a drive unit 3 is integrated. In addition, the device  of drive comprises a rack 6, which is fixed on the sliding door 1 and in this way is mobile with it.

Figures 2 and 3 show sections of the drive unit 3 according to figure 1. In this case, figure  2 shows the front side of drive unit 3 directed towards the sliding door 1, in which a cogwheel 7 it's free. Figure 3 shows a top plan view on the rear side of drive unit 3 when housing 5 it's open. As follows from Figure 3, in space inside the drive unit 3 is a motor 8, which is formed in the present case by an electric motor, and that is coupled through a gear not shown on the wheel Toothed 7. The motor 8 can move the wheel Toothed 7 in a rotating motion.

As follows, in addition, from Figure 3, at the bottom of the housing 5 are elongated holes 9. These elongated holes 9 are pierced by screws 10, which fit threaded holes not shown in socket 4 and of in this way they fix the drive unit 3 on the socket 4. Elongated drills as accommodation means for screws 10 enable an alignment of the unit drive 3 in the direction of the sliding door 1. Through from this alignment possibility the position of the sprocket 7 perpendicular to the plane of the door sliding 1, so that the sprocket 7 is engaged, during operation, with zipper 6 on the door sliding 1.

Figure 2 shows the gearwheel 7 with the rack 6 in its objective position on the sliding door 1, of so that the sliding door is not shown in this representation one.

In this objective position, the zipper 6 is fixed by means of fixing screws 11 on the sliding door 1 according to figure 1. For fixing the zipper 6 in the Sliding door 1 are provided in the zipper 6 ones 12th housings protruding from its rear side, in which respectively, an elongated drill 12b is machined. Through of the elongated holes 9, 12b the position of Zipper height 6 on the sliding door. In position objective shown in figure 2 of the zipper 6, this is fixed on the sliding door 1 such that its axis Longitudinal extends exactly in the horizontal direction. In this case, the height position of the zipper 6 on the door Sliding 1 adjusts with respect to the height position of the cogwheel 7 such that the rack 6 is guided in the cogwheel 7 with a reduced clearance, which is typically in the 1 to 2 mm range. Through this game between the wheel Toothed 7 and rack 6 ensures that rack 6 is not guided with pressure against the sprocket 7, which would lead to a unwanted wear of these components.

During the operation of the sliding door 1, the rack 6 is in this objective position and the wheel Toothed 7 is in the working position corresponding to it. He Zipper assembly 6 in the target position is performed during an assembly process. To perform during the process of mount an exact alignment of zipper 6 in position objective, the cogwheel 7 is turned in a first stage in the drive unit 3 by means of a rotating mechanism from the working position to an adjustment position. The mechanism swivel features a lever 13 (figure 3), through whose activation the sprocket 7 can be turned to the position of Adjust or work position. The engine 8 is rotated through the swivel mechanism with cogwheel 7.

Figures 4 and 5 show the gearwheel 7 in The adjustment position. In the adjustment position, the cogwheel 7 is arranged in the drive unit, displaced down facing your work position in a definite difference from the position.

In a second stage a spacer is placed in the form of a mounting ring 14 on the sprocket 7. The mounting ring 14 is constituted in this case by a plastic injection molded part. Mounting ring 14 it is configured in one piece, in fact, in the present case. In principle, the mounting ring 14 can be configured also from several parts.

The inside diameter of the mounting ring 14 symmetrical rotary is adapted to the outside diameter of the wheel toothed 7, so that the mounting ring 14 sits free of play on the sprocket 7. The mounting ring 14 is placed in the present case, as follows from figure 5, on the front front side, directed towards the sliding door 1 of the cogwheel 7 on it. So that the inner side of the ring mounting 14 sits aligned on the wheel teeth toothed 17, on the front front side of mounting ring 14 a ring-shaped projection 14a is provided, which protrudes by on the inside of the mounting ring 14 and in this way it forms a stop, which presses against the front front side of the gearwheel 7. The mounting ring is fixed through this stop 14 in position on the sprocket 7.

To facilitate the coupling of the ring mounting 14 on the gearwheel 7, the screws can be loosened  10 a bit for fixing the drive unit 3. Post that the screws 10 pass through the elongated holes 9 as housing elements in the housing 5, the housing 5 of the drive unit 3 slightly out of the slide 1, so that the sprocket 7 is better accessible for coupling mounting ring 14.

The mounting ring 14 forms an aid of mounting for fixing the zipper 6 on the door slide 1 in the desired target position. Since the thickness  of the wall of the mounting ring 14 is adapted to the difference of position of the cogwheel 7 between the working position and the adjustment position, just put the zipper 6 to mounting in the target position on the mounting ring 14. In  this support position, the zipper 6 is, as is represent in figure 4, in the corresponding height position to the target position, since the sprocket 7 is shifted down in the adjustment position in the difference of the position in front of the adjustment position and the mounting ring 14 compensates for this position difference. An essential property of mounting ring 14 for exact alignment of rack 6 is that it has a flat outer surface Sliding and zipper support 6. One way independent of the rotating position of the mounting ring 14 or of the sprocket 7, the mounting ring 14 forms in this way in its upper vertex a support surface for the zipper 6, which has a constant defined distance from the cogwheel center 7.

For mounting the zipper 6 on the door Sliding 1, zipper 6 is placed, as depicted in the Figure 4, with a segment on the mounting ring 14. In this position, the zipper 6 is firmly held and in the meantime fixed in position with a threaded rocker. Then you positioned in the elongated holes 12b of the housings of the rack 6 adjacent to the sprocket 7 some screws fixing 11 and in this way the zipper 6 is fixed in this area on the sliding door 1. Next, the sliding door 1 and thereby moves additionally Sliding sprockets 7 on the outer side of the ring mounting 14, until the rack 6 is placed with another segment defined on mounting ring 14. Also in this position of the zipper 6 is fixed again through the positioning of fixing screws 11 in the housings 12a in the area of the zipper 6, which is supported by mounting ring 14, the 6 rack locally on the sliding door 1. This process is repeat until in all housings 12a of zipper 6 fixing screws 11 are positioned for fixing on the sliding door 1.

During the zipper guide 6 on the side outside of mounting ring 14 the wheel may be locked toothed 7, that is, it can be coupled to the motor 8, of so that the sprocket 7 is not rotated through the motor 8 still. Alternatively, the gearwheel 7 may be unlocked, that is, decoupled from engine 8, so that during rack guide 6 on mounting ring 14 It can spin freely. Under symmetric configuration rotating the mounting ring 14, the rack 6 remains in this case in the height position corresponding to the position objective.

In particular, for the first case, they are conceivable spacer configurations, which deviate from the shape of a mounting ring 14. In general, the spacer is configured in such a way that its outer side forms a surface Sliding for zipper 6, which is located in a height defined in relation to the center of the cogwheel 7.

Once the zipper assembly 6 is done on the sliding door 1 the mounting ring 14 is removed outside of the cogwheel 7. Then the cogwheel 7 of New to your work position. Through the adjustment made previously of the zipper 6 it is guaranteed that in the operation of next job, the cogwheel 7 found in the Working position gears over the entire length of the zipper 6 exactly with this one. In a particularly advantageous way, the wall thickness of mounting ring 14 is configured such so that the rack 6 engages the cogwheel 7 over all its length with a predetermined game.
