    专利说明:

    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.
    In such and other generic devices, in particular, when the drive of the handrail is not positive fit, but frictionally engaged, the problem that the drive element is sufficiently firmly pressed against the handrail, so no or the smallest possible slip between the drive element and the handrail occurs.
    Another problem with such devices is the noise generated by the device, which occurs in both positive and non-positive drive systems.
    The invention is based on the object to eliminate these problems as much as possible.
    This object is achieved in a device of the type mentioned above in that on the opposite side of the handrail support rollers are arranged and that the drive element is supported by a belt on the support rollers.
    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. Furthermore, 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 thereby can dampen rolling noise that would occur when the
    Roll off support rollers 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. In the context of the invention it is therefore preferred if the belt contains a damping material, preferably a polymer, in particular rubber or polyurethane, or a silicate or is made of a damping material.
    This is particularly advantageous if the Äntriebselement 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.
    In the case of the invention, it is further preferred if the drive element has drivers which engage on the handrail. These drivers are preferably elements that cause the best possible power transmission to the handrail, especially in force or frictionally operating systems. This can be done on the one hand by the shaping or on the other hand by an appropriate choice of the material. Of course, both measures can be combined.
    According to a preferred embodiment of the invention, 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.
    Further preferred embodiments of the invention are the subject of the remaining dependent claims.
    Further features and advantages of the invention will become apparent from the following description of a preferred
    Embodiment of the invention with reference to the accompanying drawings. It shows:
    1 is a schematic side view of a device according to the invention,
    Fig. 2 shows a detail of the apparatus of Fig. 1 on an enlarged scale and
    Fig. 3 shows a section through the device along the line III-III in Fig. 2 in the region of the drive element of the device.
    The device according to the invention is a drive unit which can be arranged at any point of a passenger transport device, for example a horizontal and / or straight moving walkway or an escalator. 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 run of the handrail running back in 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 inner central region of the handrail 1, a web 3 is arranged. 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.
    In the illustrated, preferred embodiment, the drive element 4 has a roller chain 5 on whose chain links
    Driver 6 are fixed, which have an outwardly substantially V-shaped widening recess, which together form a groove, in which the web 3 is received *
    Since the power transmission in the illustrated embodiment is force or frictional, it is important that the drive element 4 is pressed with sufficient force against the web 3 on the handrail 1. For this purpose, 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 element 4 and the support rollers 7, an endless belt 9 runs, which is not driven, but is driven by a driven motor 11 via a drive element 4, since it is clamped between the drive element 4 and the support rollers 7.
    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.
    In order to adjust the contact force of the support rollers 7 via the belt 9 on the drive element 4, engage on the bracket 8 adjusting screws 15, 16, which are screwed by clamping blocks 17, 18 to a frame 19.
    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 when rolling on the support rollers 7 and at
    Contact with the roller chain 5 could arise.
    The handrail 1 has, as already mentioned in the introduction, a substantially C-shaped cross-sectional shape, the free edges 23, 24 corresponding to the lips of a C-profile being supported by rollers 25, 26 from the inside of the handrail 1 , In FIGS. 1 and 2, the rollers 26 shown on the right in FIG. 3 can be seen for illustrative reasons, although the right 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.
    It can be seen that in this embodiment (but not necessarily), 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.
