Description
Description :
The invention relates to a sectional door with a door frame, a door leaf with sections connected in an articulated manner, a weight-compensating device connected to the door leaf and an electric door drive for opening and closing movements of the door leaf, wherein the uppermost section in the closed position of the door leaf is guided as a top section on runner rails, which extend essentially horizontally up to the door frame and comprise a vertical end section at the frame side, and wherein the further sections following beneath the top section are guided in guide rails, which comprise a vertical section along the door frame, a horizontal section parallel to the runner rail guiding the top section and an arc connecting the two sections.
Sectional doors of the type mentioned at the outset must meet the safety requirements described in European standard EN 12453:2000. It is stipulated therein that a dynamic force between closing edges and counter-closing edges of maximum 400 N may occur during an opening and closing process of the door leaf. Such high forces are however only permitted for a period of at most 0.75 seconds. After the lapse of this time interval, no static force is permitted that amounts to more than 150 N. In the case of the sectional doors known in practice with the features described at the outset, a tolerated static force of 150 N is often briefly exceeded within the permitted time frame during a regular opening and closing movement of the door leaf, so that powerful door drives have to be used. If the required force to move the door leaf amounts to more than 150 N over a period of more than 0.75 s, the door drive has to be switched off by an emergency shut-off. There is a considerable risk of injury in the event of a malfunction of the emergency shut-off. It is also a problem that the drive fastened to the uppermost door leaf section in the context of the known measures is very remote from the danger point, i.e. the lower closing edge, so that there is a long force flow from the motor, via the panels connected to one another in an articulated manner, to the danger point. A reduction in the driving force of the motor does not therefore create a corresponding load relief at the danger point until after a certain delay time.
The comparatively high force requirement during the opening and closing movements with known sectional doors is based, amongst other things, on the following situation. The top section of the door leaf comprises a roller in each case at both sides, which is guided in a horizontal runner rail. The horizontal runner rails are provided at the frame side with a vertical end section, into which the rollers of the uppermost section are drawn during a closing movement of the door leaf. The rollers introduced into the vertical end pieces secure the top section in the closed position of the door leaf against unauthorised pushing open from the exterior. During an opening movement of the door leaf, the impellers of the top section first have to overcome a vertical section before they then arrive into the horizontal region of the runner rail. This lifting movement at the start of the opening movement of door leaf represents a technical problem for the electric door drive. A sectional door with the features described at the outset is known from EP-A 1 176 280. The electric door drive can be moved along a horizontal runner rail and is connected by a coupling rod to the top section. In the closed position of the door leaf, the coupling rod is aligned obliquely to the door leaf plane. The tractive force transmitted by the coupling rod during an opening movement of the door leaf has a horizontal as well as a vertical component. As a result of the vertical component, the rollers of the top section can be drawn with a travel motion of the door drive out of the vertical end section of the vertical runner rail. Powerful door drives are however required, which have the risk potential already described. With the known arrangement, it is also disadvantageous that the top section in the closed position of the door leaf and the vertical end section of the runner rail are subjected to great transverse forces at the start of the opening movement.
In the case of a sectional door known from US 2 015 402, the top section of the door leaf is guided on runner rails which extend essentially horizontally up to the door frame. No vertical end sections are provided on the horizontal runner rails. For the opening and closing movements of the door leaf, a door drive is provided which is connected either to the top section or a section beneath the top section and comprises a driven impeller constituted as a pinion. The driven impeller engages with a profile surface, which is arranged along a runner rail or guide rail.
The problem underlying the invention is to provide a sectional door with the features described at the outset, from which a reduced risk of injury arises. A favourable application of force by the door drive onto the door leaf should be guaranteed in every position of the door leaf during an opening and closing movement.
The subject-matter of the invention and the solution to this problem is a sectional door according to claim 1.
According to the invention, the door drive is fixedly mounted on one of the sections following beneath the top section and comprises a drive shaft mounted on said section with an impeller at the end which engages in the guide rail of the section and moves the door leaf.
According to the invention, the door drive is fixedly mounted on the door leaf inner surface of a section and drives an impeller, which engages in a guide rail serving to guide the sections. The guide rail has a vertical section along the door frame, a horizontal section parallel to the runner rail guiding the top section and an arc connecting the two sections. During a closing movement of the door leaf, the driven impeller runs into the vertical section of the guide rail. During a subsequent opening movement, the rollers of the top section are lifted out of the cranked end sections of the horizontal runner rail by the initially vertical travel motion of the driven impellers. Amongst other things, relatively low-power door drives can be used on account of the favourable application of the force, so that the risk of injury during an opening and closing movement of the door leaf is reduced.
According to a preferred embodiment of the invention, the door drive is fastened to the lowermost section in the closed position of the door leaf. Surprisingly, the force required to move the door leaf after the rollers of the top section had been lifted out of the cranked end sections of the horizontal runner rail is significantly reduced compared to the prior art. Through the arrangement of the door drive at the lowermost section in the closed position of the door leaf, there is also a short flow of force between the door drive and the potential danger point at the bottom of the closing edge of the door leaf, so that a shut-off of the door drive leads to a very rapid load relief at the danger point.
According to the invention, the door drive is dimensioned such that the maximum driving force for moving the door leaf does not amount to more than 150 N. In the case of the arrangement of two or more motors, the dimensioning accordingly takes place such that the total maximum driving force lies below the stated limiting value. In the case of the arrangement of the door leaf drive according to the invention, the stated critical force values of more than 150 N are not reached during the regular opening and closing process of a door leaf which has standard dimensions for a garage with parking places for one or two cars, so that the function of the door leaf is guaranteed even with the reduced driving power of the door drive. The dynamic range between 150 N and 400 N explained at the outset, within which an increased risk of injury is present, can therefore never be reached. An emergency shutoff in the event the critical value of 150 N being exceeded over a period of more than 0.75 s is therefore unnecessary. Alternatively, the emergency shut-off can be set to a lower limiting force value. Apart from the advantage that a system is provided which is inherently lower-risk in terms of injury, there are also cost advantages on account of the use of a smaller door drive.
The door drive can be a bifurcation gear mechanism for two drive shafts, which extend up to the two sides of the sections and comprise impellers which engage in the guide rails at the ends. It is also possible for a door drive with in each case only one drive shaft to be provided at one or at both sides of the door leaf. The guide rails expediently have a C-shaped cross-sectional profile, wherein one leg of the profile is constituted as a channelshaped running surface and the other leg forms a support surface arranged at a distance from the running surface.
According to the invention, the driven impeller interacts with a flexible power transmission train held under tension in the guide rail. In this embodiment, guide rollers are provided, as viewed in the opening movement direction, in front of and/or behind the driven impeller, said guide rollers pressing the driven impeller against the power transmission train, so that the power transmission train partially surrounds the driven impeller. A guide roller can for example be provided in front of or behind the driven impeller, so that the power transmission train surrounds the driven impeller in a Z-shaped manner. In this case, tensioning stations for maintaining the tension during an opening and closing process of the door leaf are expedient at the two ends of the power transmission train. Furthermore, guide rollers can be provided in front of or behind the driven impeller, so that the power transmission train surrounds the driven impeller in a loop-shaped manner. In this case, a tensioning station only needs to be provided at one end of the power transmission train.
There are also various possibilities for the structural design of the driven impeller and the power transmission train. The driven impeller can be constituted as a pinion, which engages with the power transmission train constituted as a toothed belt or chain. The driven impeller can alternatively also comprise a U-shaped running surface delimited by side flanks, wherein the power transmission train is then expediently constituted as a cable. Furthermore, it is also possible that the power transmission train is constituted as a bead chain, which comprises a core and a multiplicity of bodies each fastened to the core with equal spacing, and that the driven impeller comprises a U-shaped running surface delimited by side flanks, said running surface comprising depressions adapted to the bodies of the bead chain in the bottom of the running surface.
The invention is explained below with the aid of a drawing representing only one example of embodiment. In the figures, diagrammatically:
Fig. 1 shows the internal view of a sectional door according to the invention in a perspective representation,
Fig. 2 shows a force diagram of the tractive force measured during the opening movement of a sectional door,
Fig. 3 shows a further embodiment of the invention,
Fig. 4 and 5 show further embodiments of the arrangement according to the invention, also in detail, and
Fig. 6 shows section A-A in fig. 5.
The sectional door represented in fig. 1 and 3 comprises in its basic structure a door frame 1, a door leaf 2 comprising sections 3, 3' connected in an articulated manner, a weight-compensating device 4 connected to door leaf 2 and an electric door drive 5 for the opening and closing movements of door leaf 2. In the example of embodiment, weight-compensating device 4 is constituted as a torsion spring shaft, which is connected by a traction cable to the lower section of the door leaf.
The uppermost section in the closed position of the door leaf is guided as top section 3' on runner rails 6, which extend essentially horizontally up to door frame 1 and comprise a vertical end section 7 at the frame side. Further sections 3 following beneath top section 3' are guided with rollers 8 in guide rails 9, which comprise a vertical section along door frame 1, a horizontal section parallel to runner rail 6 guiding top section 3' and an arc connecting the two sections.
In the example of embodiment of fig. 1, door drive 5 is fastened preferably laterally to section 3 that is lowermost in the closed position of the door leaf and comprises a drive shaft 10 mounted on section 3 with an impeller 11 at the end. The driven impeller 11 engages in guide rail 9 and moves door leaf 2. In the example of embodiment of fig. 3, the door drive 5 comprises a bifurcation gear mechanism for two drive shafts 10, which extend up to the two sides of section 3 and comprise impellers 11 at the ends which engage in lateral guide rails 9. The door drive is arranged on a section 3 connected beneath top section 3' .
The tractive force acting on the door leaf during an opening movement of the door leaf is represented in fig. 2. The course represented by a dashed line shows measured values on a sectional door with a door drive constituted as a ceiling-mounted pulling mechanism according to the prior art, which is connected by a coupling rod to the section of the door leaf that is uppermost in the closed position. The measured values for a sectional door which is provided with a door drive according to the invention on the lowermost section are represented with a thicker, continuous line. A comparison of the measured values makes clear that, as a result of the arrangement according to the invention, the forces for a movement of the door leaf can be markedly reduced, smaller force variations occur during the movement of the door leaf and a safe distance from the maximum static force of 150 N permitted according to European standard EN 12453:2000 is complied with.
In the examples of embodiments of fig. 4 to 6, driven impeller 11 interacts with a flexible power transmission train 18 held under tension in guide rail 9.
Driven impeller 11 is constituted as a pinion in fig. 4, which engages with power transmission train 18 constituted as a toothed belt. Toothed belt 18 wraps partially around pinion 11. In the running direction before and after the pinion, guide rollers 19 are provided, which, just like rollers 8 of further sections 3, run on the rear of toothed belt 18. Tensioned belt 18 transmits the forces required for the opening and closing movements. For the tensioning of toothed belt 18, a tensioning station 20 is provided at one end thereof.
Power transmission train 18 is constituted as a bead chain in fig. 5, which comprises a core 23 and a multiplicity of bodies 24 each fastened to core 23 with equal spacing. Driven impeller 11 comprises a U-shaped running surface 26 delimited by side flanks 25, said running surface comprising depressions 27 adapted to bodies 24 of bead chain 18 in the bottom of the running surface (see fig. 6). In this example of embodiment, only one guide roller 19 is provided in front of driven impeller 11, as viewed in the opening movement direction, so that the bead chain 18 wraps around driven impeller 11 in a Z-shaped manner. In order to maintain the tension during an opening and closing process of door leaf 2, tensioning stations 20 are provided at the two ends of bead chain 18.
