EP2227615B1 - Drive system for a gate - Google Patents

Description

The invention relates to a drive system for a gate.

The door, which is driven by the drive system, is in particular formed by a louvered door, which is typically a garage door.

The slats of the door are guided laterally in guide rails, which are guided along the door frame and along the ceiling of the garage. Known drive systems for such gates have a motor guided on one of the guide rails. The motor is mounted on a bracket or the like, which is movably mounted on rollers in the guide rail. On the console a push rod is articulated, which is also hingedly connected to the top plate. By moving the motor along the guide rails, the door is opened or closed.

A problem with such drive systems is that they must be individually adapted to the respective gate with the guide rails. This individual adaptation of the drive systems means that the manufacturing costs for the drive systems are undesirably high.

The DE 198 08 696 A1 relates to an electromechanical garage door drive consisting of a mounted on the garage ceiling guide rail, coupled to the door by means of a joint rod, a carriage and a drive motor having drive unit and a running parallel to the guide rail, attached to this and engaging with the drive motor chain. The power supply for the drive motor via the guide rail and a guide rail parallel lying power supply means. The guide rail is formed by the existing ceiling rail for receiving the gate. The chain is firmly clamped at one end of the ceiling rail and clipped into this at the other end of the ceiling rail and provided there with clamping means. Further, the power supply means is the chain.

The EP 1 496 185 A1 relates to a sectional door with a multi-part door leaf of hingedly connected and guided in lateral guide rails panels, connected to the door leaf weight compensation device and with an electric door drive with at least one tractor, which is guided with rollers in one of the lateral guide rails and movable by a coupling rod connected to the door leaf. The tractor has an electric motor driven drive wheel, which meshes with a tensioned along the travel traction means. On the guide rail associated with the tractor, a flexible channel profile following the rail track is fastened, into which the traction means stretched at the end is inserted.

From the DE 41 05 872 A1 a drive system for a sliding gate is known which comprises a guide carriage on which a drive member is provided, which is driven by means of a drive. The guide carriage is hinged to a door leaf via a connecting rod.

The invention has for its object to provide a drive system for a gate, which has a high functionality and is also rational and inexpensive to produce.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

This creates a particularly simple connection of the push arm and the carriage. The connection is in the form of a plug connection which can be produced without tools or the use of further fastening means. The assembly of the push arm on the carriage can thus be made very quickly and without tools.

In the drive system according to the invention, different traction means such as belt straps, belts, toothed belts can be used, which are in engagement with the motor.

Particularly advantageous drive system of the invention is designed as a chain drive. On a shaft of the motor, a sprocket is then mounted, which is guided during operation of the drive system in engagement with a guided along the guide rail chain.

Particularly advantageous are a chain channel in which the chain is guided and a busbar with electrical lines for power supply, fixed to a sliding guide of the carriage.

This achieves a particularly high modularity of the drive system. The chain guide with the busbar, which are particularly advantageously formed in one piece, are attached independently of the guide rail on the sliding guide as an application-specific element of the carriage. For attachment of the chain rail and the busbar therefore no structural intervention on the guide rail need to be made.

The drive system according to the invention can thus be mounted either simply on one of the guide rails, without any constructive interference with the existing door system.

The power supply of the motor can be structurally simple in that in the carriage electrically contacted with the motor circuit board is mounted, protruding from the circuit board pins, which are in contact with the electrical lines of the busbar.

The printed circuit board itself with its connections to the motor can be used as a universal component. This can preferably also apply to the contact pins on the printed circuit board, if the adaptation of the bus bar on the carriage is designed so that the contact pins can be used for different configurations of busbars.

Particularly advantageously, the drive system according to the invention has a manually actuated emergency release in order to still be able to open the door manually even in the event of a power failure.

Particularly advantageous sitting to form the emergency release of the motor on a motor mounting plate, which is mounted by means of a pivot bracket and a latching connection on the push arm. To actuate the emergency release latching connection is releasable. The motor is automatically pivoted downwards, whereby the sprocket is released from the chain. In this case, the pivoting process can be triggered by gravity or by spring forces.

This emergency release has low functional complexity on a high reliability.

The FIGS. 1 and 2 show an embodiment of a drive system 1 for a goal designed as Lamellentor gate. The gate is designed in the present case as a garage door. The slats of the door are guided laterally in guide rails 2, wherein in FIG. 1 one of the guide rails 2 is shown. The identically formed guide rails 2 have, as from FIG. 1 can be seen, an upper rail element 2a and a lower rail element 2b, which extend below the ceiling of the garage. In the upper rail element 2 a, the uppermost fins of the door can be guided by means of rollers, while in the lower rail element 2 b the rollers of the adjoining fins are guided. Furthermore, the guide rails 2 also extend laterally of the door opening, which can be closed with the gate.

The drive system 1 can optionally be attached to one of the guide rails 2. In this case, the drive system 1 is arranged to ride on one of the guide rails 2, wherein by moving the drive system 1, the door is opened or closed.

The drive system 1 has a motor 3 designed as an electric motor. The motor 3 is mounted on a push arm 4, which forms the connection to the gate. The push arm 4 is in FIG. 3 presented in a single representation. The push arm 4 has a bore 5, in which the uppermost lamella of the door can be coupled in an articulated manner with a fastening means, not shown.

The motor 3 can be mounted directly on the push arm 4 in the simplest case. In the present case, the motor 3 is mounted on a motor holding plate 6, wherein the motor holding plate 6 is in turn attached to the push arm 4. The motor retaining plate 6 is part of an emergency release and is in FIG. 4 presented in a single representation.

How out FIG. 4 can be seen, the motor holding plate 6 has three receiving holes 7, in which not dargstellte screws are introduced to tighten the motor 3 to the motor mounting plate 6. In the center of the mounting holes 7 is a through hole 8, through which the shaft of the motor 3 is guided when it is fixed on the motor mounting plate 6.

For fixing to the push arm 4, the motor holding plate 6 has a latching pin 9 and a bore 10. The locking pin 9 has a projecting over the underside of the motor retaining plate 6 locking element 9a, which can be engaged in a breakthrough 11 in push arm 4. The protruding over the top of the motor support plate 6 part of the detent pin 9 forms a handle 9b, by means of which the locking element 9a can be released manually from the opening 11.

The bore 10 can be inserted into a protruding from the push arm 4 bolts 12. How out FIG. 2 can be seen by insertion of the bolt 12 into the bore 10 on the projecting beyond the bore 10 end of the bolt 12, a bolt head 13 is placed, whereby a safeguard against detachment the motor holding plate 6 is reached by the push arm 4. By this fastening means, the motor holding plate 6 is firmly fixed to the push arm 4.

The push arm 4 is hinged to a carriage 14 which is movably mounted on the guide rail 2. FIG. 5 shows the thrust arm 4 facing side of the carriage 14th FIG. 6 shows the side facing away from the push arm 4 of the carriage 14th

The carriage 14 is plate-shaped and has a circular opening 15. At opposite, the opening 15 delimiting edge segments 4, two identically designed guide elements 16 are provided as means for coupling to the thrust arm, which protrude from the thrust arm 4 facing side of the carriage 14. The guide elements 16 extend along the edge segments and are designed as bar-shaped elements 16a, of which in each case a projection 16b protrudes on the side facing away from the opening 15.

As a coupling means for coupling to the guide elements 16 of the carriage 14, the push arm 4 has a recess 17 opening at a longitudinal end. The recess 17 is limited at the front end, that is in the region of the mouth, and at the rear end of two rectilinear, parallel edge segments of the push arm 4. The middle part of the recess 17 is bounded by two edge segments running along a circular arc.

The widths of the rear and front part of the recess 17 are slightly larger than the distances between the longitudinal edges of the guide elements 16. The diameter of the central part of the recess 17 is slightly larger than the diameter of the circle along which the outer lateral surfaces of the bar-shaped elements 16 a Guide elements 16 run. The heights of the bar-shaped elements 16 a are slightly larger than the thickness of the push arm 4 in the region of the recess 17.

For coupling the push arm 4 to the carriage 14, the recess 17 of the push arm 4 of an insertion direction on the carriage 14 is inserted resting, so that the guide elements 16 are inserted into the recess 17. Then, the push arm 4 is rotated, so that the projections 16 b engage behind the edge segments of the push arm 4, which limit the arcuate portion of the recess 17. As a result, the push arm 4 is secured against detachment from the carriage 14. The rotatably mounted at the edges of the recess 17 guide members 16 form a hinge connection between the push arm 4 and carriage 14th

This pivot bearing between the push arm 4 and carriage 14 forms a universal coupling of the two parts. Incidentally, the carriage 14 forms the only application-specific part of the drive system 1. For coupling to different gate systems, in particular guide rails 2, therefore, only the carriage 14 must be changed in the drive system 1 according to the invention.

FIG. 6 shows the guide rail 2 facing side of the carriage 14 with the application-specific components. Of the carriage 14 are two receptacles 18 show, to which rollers 19 are attached, which, as in FIG. 2 represented, are guided in the guide rail 2, whereby the carriage 14 is movable on the guide rail 2.

Along the upper side of the carriage 14 runs a rail-shaped sliding guide 20. At this sliding guide 20, which lies laterally to the guide rail 2, a chain channel 21 is fixed, in which a chain 22 along the guide rail 2 extends. In operation of the drive system 1, the chain 22 is engaged with a sprocket 23 which is seated at the free end of the shaft of the motor 3. The motor 3 drives the sprocket 23, causing it to run in the chain 22, thus moving the drive system 1 along the guide rail 2, thereby opening or closing the door.

The power supply of the motor 3 via a bus bar 24, in which electrical lines 25 are guided. The busbar 24 is formed integrally with the chain channel 21.

In the carriage 14, a rectangular opening 26 is provided ( FIG. 6 ) in which a printed circuit board 27 is fixed with electronic components for controlling the motor 3 ( FIG. 1 ). On the circuit board 27 are not shown contact pins which are in electrical contact with the electrical lines 25 in the bus bar 24, whereby the power supply of the motor 3 is ensured.

From the guide rail 2 facing side of the carriage 14 is a holding element 28 protrudes, which forms mounting pins for mounting the drive system 1 on the guide rail 2. With the holding element 28, the carriage 14 can be hung on the upper rail element 2a of the guide rail 2. In this position, further assembly steps, in particular the attachment of the sprocket 23 can be performed on the shaft. After installation of the carriage 14 is in his in FIG. 2 shown target position in which the holding element 28 is lifted again from the upper rail element 2a.

The motor holding plate 6 mounted on the push arm 4 forms the central element of the emergency unlocking of the drive system 1, which is performed manually by an operator, for example in the event of a power failure. For this purpose, the locking element 9a is released from the opening 11 of the push arm 4 by pressing the handle 9b of the detent pin 9. A rope or the like may be attached to the handle 9b so that the manual unlocking can be performed from the outside of the garage. Once the locking element 9a is released from the opening 11, the motor mounting plate 6 depends only on the pin 12 of the push arm 4, which forms a pivot bearing. Due to gravity then falls the motor 3 down, the motor holding plate 6 is pivoted relative to the pivot bracket, that is with respect to the bolt 12. This will do that Sprocket 23 moves down and thus disengages from the chain 22, that is, the emergency release of the drive system 1 is completed.
