Definitions

• the invention relates to a door drive device with a motor drive unit and an attached guide rail of a slide movably guided along the latter, to which a drag connection to the door leaf movably guided between its end positions is connected on the output side and which is connected on the drive side via a traction means in the form of an endless strand from a chain, a Rope, a toothed belt or the like is geared to the motor drive unit, which traction means engages in a drive wheel rotatably connected to the output shaft of the motor drive unit, engages around a deflection element arranged in the end region of the guide rail facing away from the drive wheel, and with its longitudinal strut running therebetween two exceptions Carriage passes through, wherein one of the two longitudinal strands is connected to the carriage.
• the object of the invention is to design a door drive device of the type mentioned at the beginning with less noise.
• the door drive device is further developed in that the recess of the slide penetrated by the other of the two longitudinal strands is provided at least on one of the side walls delimiting the recess with at least one damping formation projecting into the recess, on which this longitudinal strand is not connected to the slide of the traction means attacks at least when it is deflected in a direction perpendicular to its longitudinal direction due to a beginning vibration.
• the area of attack with which the damping formation detects the longitudinal strand that is not attached to the slide, at least during its oscillating movement perpendicular to its longitudinal direction is preferably designed as a protruding edge.
• the free oscillating length of this free longitudinal strand is shortened, so that in principle only less problematic vibrations of a higher frequency could lead to a resonance.
• this free oscillating length is constantly changed by the movement of the slide and the damping formation which is carried along with it and acts on the longitudinal strand.
• the resonance frequency of the longitudinal strand also changes continuously, so that resonances can only arise briefly and are practically prevented.
• a swinging up of vibration amplitudes is effectively prevented.
• the rattling noises present in known door drive devices do not occur in the door drive device according to the invention. Overall, the door drive is smoother and more even.
• the free longitudinal strand can thus be guided through the attack on the edge or other attack area of the damping formations at the beginning of the swinging movement, so that it cannot swing in the recess in the slide.
• damping designs are provided on the side walls, which are opposite to the plane of deformation which leaves the traction means when deflected around the drive wheel and the deflecting element.
• the free longitudinal run runs closest to the guide rail wall, which is why there could be the most likely rattling noises, but this is effectively prevented by the damping designs.
• the damping designs are preferably provided in the recess on all sides of the free longitudinal strand of the traction means, which effectively prevents all vibrations, including those from the level of the traction means, even with more flexible traction means such as ropes.
• the damping configurations are preferably designed as material-saving ribs, which extend in the longitudinal direction over a large part of the dimension of the recess, and / or are made in one piece with the slide.
• the damping designs are preferably designed to taper as seen from the respective delimiting inner side wall of the recess of the slide to the edge or similar attack area protruding into the interior thereof.
• these are provided with oblique start-up shoulders for a gentler introduction and passing of the longitudinal run past the damping designs.
• the free longitudinal run runs even more silently and easily, if the damping design does not touch the longitudinal strand in the non-vibrating state and only leads when the vibration begins.
• the edges of the damping configurations are spaced slightly apart from the free longitudinal strand in the non-oscillating longitudinal orientation.
• the dimensions of the damping formations are adapted to the external dimensions of the tooth formations.
• the slide and the damping formations arranged therein and possibly integrally embodied therewith can consist, for example, of plastic or light metal.
• FIG. 1 is a sectional view from below of a guide rail with a carriage driven therein by means of traction means
• Fig. 2 is a front view of the carriage of Fig. 1 and
• Fig. 3 is an enlarged bottom view of the carriage in section along the
• Fig. 1 is shown by means of a lintel attachment 11 on the lintel above a garage door opening, not shown, guide rail 1 of a door drive device.
• a slide 5 is guided in the guide rail 1 and is movable in the guide rail 1 via a traction means 2 and is articulated via a driving eye 54 as a drag connection to a door leaf (not shown) to be moved between an open and a closed movement.
• the traction means 2 is an endless strand via a drive wheel 3 connected to a motor drive unit, not shown, arranged in a fixed manner in the guide rail 1 at an end facing away from the lintel and at the end facing the lintel via a guide roller 4 arranged in a fixed manner in the guide rail 1.
• the traction means 2 With its longitudinal strands 22 and 23 running between the rollers 3 and 4, the traction means 2 extends through recesses in the form of sled channels 52 and 53 running longitudinally to the guide rail 1 in the sled 5.
• a traction means coupling 21 is arranged, on which the one Longitudinal strand 22 % of the traction device 2 is fastened.
• the other longitudinal strand 23 is freely movable in the longitudinal direction through the second slide channel 53 depending on the door movement.
• the traction mechanism coupling 21 is connected to the carriage 5 in the first carriage channel 52 via a carriage driver 51. As best seen in FIG.
• the traction means 2 comprises a belt 25 made of textile or similar material, around which bodies 26 made of plastic or the like are injection molded around the belt 25 at regular intervals. These bodies serve as tooth formations 26 with which the traction means 2 engages in corresponding recesses, not shown, in the running surface of the drive wheel 3. A rotation transmitted from the motor drive unit to the drive wheel 3 is thus transmitted to the traction means 2. In the course of its rotation, the traction means 2 pulls the carriage 5 through the guide rail 1 by means of the longitudinal strand 22 via the traction means coupling 21 and the carriage driver 51, which sliding movement is transmitted to the door leaf via the driver eye 54. - -
• the slide channel 53 through which the free longitudinal strand 23, which is not connected to the slide 5, is guided, has on its side walls 57 and 58 with elastic, thin, longitudinally extending to the slide channel 53 as damping designs for damping Vibrations of the free longitudinal strand guide webs 55 provided.
• the guide webs 55 are tapered from the respective side wall 57, 58 towards the traction means 2 and terminate at the traction means hm with an edge 59 which runs only a short distance from the outer dimensions of the tooth formations 26, so that the traction means 2 is guided almost without contact in the slide channel 53 through the guide webs 55.
• the guide webs 55 are provided over the entire length of the slide channel 52 and have run-on shoulders 56 at the ends of the shaft channel, which introduce the tooth formations 26 m to lighten the space between the edges 59.
• the guide webs 55 are made integrally with the slide 5 and, like this, are made of plastic or light metal, for example.
• the guide webs 55 can also be retrofitted into the slide channel 53 insertable insert arranged smd
• a sol cher use would be suitable for retrofitting existing sleds
• the function of the guide webs 55 is described below.
• the free long strand 23 has a length L predetermined by the spacing of the rollers 3 and 4, on which the free long strand 23 could freely swing without the guide webs 55.
• the long string 23 could hit the guide rail 1 at a sufficiently high amplitude, which would cause unpleasant rattling noises.
• the free long string 23 was guided through the edges 59 of the guide webs 55 but effectively prevented such Rock up and shorten the fre he vibration length L of the long strand 23
• the free vibration length L also constantly changing, which results in a constant change in the resonance wavelength ⁇ , so that resonances are practically prevented.
