Definitions

  • the invention relates to a handrail drive system, a handrail guidance system, a handrail and a device as described in the preambles of claims 1, 16, 21 and 51.
  • Handrails serve above all to increase the transport safety for individuals to be transported by means of escalators, moving walks or similar devices, in particular persons, handrails used in these areas of application at least in some areas as
  • the handrails are usually designed in the form of endless belts, which are continuously driven by means of a drive system and are carried by deflection rollers, the handrail being guided on the top of a balustrade so that it can be accessed by individuals and on the underside of the balustrade to form an endless loop preferably inaccessible, especially in a substructure which has the drive system.
  • the handrails usually have an approximately C-shaped cross-sectional profile, and because of the length / thickness ratio of C-shaped cross-sectional profiles which is unfavorable for the tensile strength in cross-section, they are formed by several layers of different materials, for example special layers for increasing the tensile strength are.
  • the handrail known in the prior art therefore has the disadvantage of cost-intensive manufacture, since in order to maintain the necessary component characteristics, e.g. high tensile strength, scratch resistance, geometry resistance, etc., the handrails can only be produced in a complex manufacturing process using conventional vulcanization or extrusion processes, since the manufacture of the handrail formed as a multi-layer composite part requires a complex preparation of semi-finished products.
  • a handrail drive with a handrail driven by this is shown for example in DE 198 50 037 AI.
  • a handrail drive pulley Pressure brought into contact with a handrail drive pulley is connected to a drive wheel by a drive chain.
  • Applying pressure on the handrail using a handrail drive pulley drives the handrail, with the Handrail drive pulley includes a variable air pressure hose installed on a peripheral surface of the handrail drive pulley, whereby the handrail is in pressure contact with the handrail drive pulley.
  • the handrail is designed in the manner of a C-shaped profile.
  • EP 0 528 387 B1 Another drive arrangement for a movable handrail is shown in EP 0 528 387 B1, the handrail interacting with an endless drive belt and the drive belt being guided around a pair of spaced deflection rollers.
  • an endless counteracting belt is arranged on an opposite surface, which interacts with the handrail and is guided around spaced end rollers.
  • the handrail itself has a C-shaped cross-sectional profile.
  • the object of the present invention is to design a handrail drive system, a handrail guidance system and a handrail in such a way that they can be manufactured more easily and more cost-effectively. Furthermore, it is part of the object of the invention to enable a compact structure and a long service life for the components mentioned.
  • the object according to the invention is achieved independently by the features in the characterizing part of claims 1 and 21, respectively.
  • the resultant advantage lies primarily in the fact that the mating material pairing between drive element and handrail with a static friction coefficient greater than or equal to 0.95 forms a reliable frictional connection in the contact area with low required surface pressure, so that when the drive element moves relative, the handrail applied to it can be reliably driven.
  • the occurrence of sliding friction in the contact area of the material pairing can essentially be ruled out, so that a friction drive with very high operational reliability is created.
  • a further development according to claim 2 is advantageous since the rotational movement of a drive motor can be converted directly into a linear movement of the handrail in cooperation with the handrail by means of a drive wheel.
  • the risk of sliding friction occurring in the system area can be reduced by the special material properties of rubber.
  • An embodiment variant according to claim 4 has the advantage that the frictional connection between the drive element and handrail in the contact area can be achieved or increased by expansion of the friction body, since the contact pressure between the contact surfaces can be varied by changing the volume of the friction body.
  • the use of a hollow body such as an air-inflatable rubber tire is particularly advantageous since the elastomeric rubber material has good static friction properties and, in addition, the contact pressure between the two contact surfaces in the contact area can be increased by changing the air pressure in the rubber tire.
  • a variant according to claim 5 is advantageous because fiber-like structures, e.g.
  • Microfibers which have increased adhesion properties to surfaces the adhesion of the contact surfaces to one another in the contact area can be increased.
  • An embodiment according to claim 6 has the advantage that the material of the drive element can be applied by a separate component, as a result of which inexpensive supplier or mass components can be used. In the case of drive wheels, this can be carried out in a particularly simple manner in a particularly simple manner by means of bearing shells or bearing sleeves with high surface friction.
  • An embodiment variant according to at least one of claims 7 or 8 or 23 is from
  • the embodiment variant according to claim 9 or 22 has the advantage that the drive element in connection with a handrail can be embodied in a space-saving manner in a substructure or a balustrade, for example an escalator.
  • drive elements arranged laterally to the handrail in particular drive wheels, act laterally on the pressure force on the handrail, ie that lifting the handrail upwards, which is not desired, is made difficult or prevented becomes.
  • the power transmission to the handrail can be additionally secured by means of a plurality of drive elements, and a failure of individual drive elements can be compensated for by increasing the operational safety by means of a plurality of drive elements.
  • An embodiment variant according to claim 13 has the advantage that the force transmission to the handrail is improved by a positive connection between the handrail and drive element and at the same time an unwanted detachment of the handrail from the drive element is made more difficult, the embodiment variants according to at least one of the
  • Claims 14 or 15 describe particularly advantageous positive configurations for the frictional connection of a drive wheel to the handrail.
  • the invention is also solved independently by the features in the characterizing part of claim 16.
  • the resultant advantage lies above all in the smoother reliability of the handrail and the handrail guidance system relative to one another, as a result of which the material wear of the guide element resting on the handrail can be kept low. Furthermore, due to the reduced frictional resistance, a lower driving or conveying force acting on the handrail is necessary to drive it, which means that smaller-sized or more economical handrail drive systems with longer maintenance intervals can be used.
  • the friction coefficients specified in claim 25 prove to be particularly advantageous.
  • the embodiment variant according to at least one of claims 19 or 20 is advantageous because whereby the handrail can be displaced along its longitudinal extent on the sliding surface relative to the guide element and by a form-fitting interaction of the guide element with the handrail, for example in a recess, it is possible for the handrail to be essentially stable in a direction transverse to its longitudinal direction and is secured against lifting off on the handrail guidance system and this can only be moved in its longitudinal direction.
  • an embodiment variant according to claim 24 is advantageous because, by means of a handrail with a handrail surface divided into several contact areas, in particular in sections, with different friction properties in the contact areas, the different operative connections that the handrail enters into, on the one hand a frictional operative connection with the drive element , on the other hand, with the guide system, a sliding connection can be realized in a simple manner.
  • the different handrail functions with regard to adhesion or sliding effect are thus decoupled from one another, whereby the respective functions can be optimized and changed independently of one another, so that a very high drive power can be transferred from the handrail drive system to the handrail.
  • a compact and low-maintenance construction of a system, comprising the handrail according to the invention, is therefore possible.
  • An embodiment variant according to claim 26 is also advantageous, since a handrail surface formed from a uniform material can be provided with different surface roughnesses in the different sections due to area-specific surface treatments and thus can be brought into a condition required for a friction fit or sliding suitability, thereby Production of the handrail can be simplified.
  • the different Areas and functions of the handrail provided are decoupled from one another by the specified structure and can be adapted to their specific requirements, the handrail essentially having a known, for example double-T-shaped, cross-sectional profile.
  • the handrail can be used easily and safely for individuals by a special gripping surface on the upper belt.
  • the embodiment variant according to claim 31 is advantageous in that the risk of injury to persons gripping the handrail and the damage to the handrail or drive or guide system by penetration of external objects into it can be prevented by means of guide elements or handrail drive system elements hidden by the handrail ,
  • An embodiment variant according to claim 32 is also advantageous, as a result of which stresses occurring in the area of the guide or drive system of the handrail are limited to the area of the lower chord and its properties can be optimized essentially decoupled from the upper chord.
  • the manufacture of the handrail can advantageously be simplified by reduced tool preparation and cycle times during manufacture can be shortened.
  • Formations according to at least one of claims 34 to 36 are advantageous since the dimensions specified form a handrail which is dimensionally stable and has good strength properties, but which, at the same time, is secured against unintentional detachment from the handrail guidance system by adequate engagement of the handrail guidance system and is simultaneously guided with low wear.
  • An embodiment variant according to claim 37 essentially brings with it the advantage of additionally increased tensile strength properties of the handrail.
  • invention variants according to at least one of claims 38, 39 and 40 are of Advantage, because the specified profile cross-sections and their surface dimensions can form a one-piece and flexible handrail with sufficient tensile strength properties for use with escalators or moving walks, whereby the handrail does not have to have additional layers that increase the tensile strength, so that handrail production through simplified tool preparation can be accelerated and reduced in costs.
  • An embodiment according to claim 42 is advantageous because by means of material pairings, in which at least one material is formed from an elastomeric material, in particular rubber, a non-positive or frictional transmission of movement is possible with less surface pressure than by means of non-elastomeric material pairings , which minimizes wear on the components and extends maintenance intervals.
  • An embodiment according to the features of claim 43 has the advantage that the contact surface in the contact area is limited by the profiling to the area of its elevations and the total contact surface can be reduced to reduce the sliding resistance between the handrail and guide element. In contrast, however, it is also possible to advantageously increase the adhesion between the drive element and the handrail by means of a combined friction and form fit.
  • the different coefficients of friction in the different plant areas can be achieved by the selection of specifically suitable, different materials or sliding layers and can be maintained essentially permanently and maintenance-free.
