Definitions
- the invention relates to a device for driving a handrail of a passenger conveyor with an endless drive element which is driven by a motor.
- Such a device is known for example from DE 11 2006 004 175 T5.
- the invention is based on the object to eliminate these problems as much as possible.
- the belt performs two tasks in the present invention.
- the belt spans the distance between the support rollers so that the force from the support rollers acts evenly distributed on the handrail.
- the belt which runs freely between the handrail and the support rollers and therefore does not have to transmit tensile forces, can be made of a material which has good damping properties and thus rolling noise can dampen, which would occur if the support rollers roll directly on the drive element. Consequently, it is therefore also advantageous if the belt, unlike for belts in this technical field otherwise usual, is made of a very elastic material.
- the belt contains a damping material, preferably a polymer, in particular rubber or polyurethane, or a silicate or is made of a damping material.
- the drive element is a chain, in particular a roller chain.
- Chains, particularly roller chains, are preferred in the invention for the reason that they can transmit high forces and are relatively insusceptible to wear.
- Drive element has drivers who attack the handrail. These drivers are preferably elements which are as good as possible, especially in the case of force or friction-operated systems
- an improvement of the non-positive connection by means of molding can take place in that the drivers have a substantially V-shaped widening recess into which a web arranged on the handrail engages, preferably with a substantially V-shaped cross section.
- Fig. 1 is a schematic side view of an inventive
- Fig. 2 shows a detail of the device of Fig. 1 in enlarged
- Fig. 3 is a section through the device along the line
- the device according to the invention is a drive unit which is located at any point in a passenger transport device,
- a horizontal and / or straight walkway or an escalator can be arranged. It can be seen that with the device according to the invention, a handrail 1 can also be driven in the upper area of a balustrade 2, so that no additional space is required under the strand of the handrail which runs back into the lower area of the balustrade. It is understood that the device according to the invention but also rotated by 180 ° could be used to drive the returning strand.
- the handrail 1 has in the illustrated embodiment, a substantially C-shaped cross-section, wherein in the interior
- This web 3 may theoretically have teeth for a positive engagement of a drive element 4, but in the present invention is preferably continuous and is therefore driven by the drive element 4 only force or frictional.
- the drive element 4 has a roller chain 5, on the chain links of which drivers 6 are fastened, which extend outwards in the
- support rollers 7 are provided according to the invention, which are rotatably mounted on a holder 8.
- the support rollers 7 are arranged on the handrail 1 opposite side of the drive element 4, wherein according to the invention between the drive member 4 and the support rollers 7, an endless belt 9 runs, not driven itself, but driven by a motor 11
- the belt 9 runs around two deflection rollers 12, 13 before and after the holder 8 or the support rollers 7 and about a tension roller 14, which is arranged below the holder 8.
- the drive element 4 is a first gear 20 and a second gear 21 and a not recognizable in detail drive pinion, which is driven by the motor 11 via a gear 22.
- the belt 9 is preferably made of a material containing a polymer, preferably rubber or polyurethane, and has good damping properties to prevent noise, which could arise when rolling on the support rollers 7 and 5 in contact with the roller chain.
- the handrail 1 has, as already mentioned in the introduction, a substantially C-shaped cross-sectional shape, wherein the free edges 23, 24, which correspond to the lips of a C-profile, from the Inside of the handrail 1 ago by rollers 25, 26 are supported.
- the rollers 26 shown on the right in FIG. 3 can be seen for illustrative reasons, although the right-hand part of the frame 19 with the rollers 26 is not actually shown in these figures in order to provide a view of the interior of the invention Release device.
- the rollers 25, 26 are arranged in the region of the guide rollers 12, 13 and therebetween in the region of the support rollers 7 at a closer distance than in the before and then subsequent areas to the Handrail 1 support well against the forces acting on the handrail 1 by the drive element 4 and to ensure a sufficiently strong connection between the drivers 6 and the web 3 on the handrail 1.
