Definitions
- the invention relates to steps or pallets with special step cheeks or cheeks for driving devices according to the preamble of claim 1 and driving devices with such steps or pallets according to claim 12.
- Driving devices in the sense of the invention which can also be referred to as conveyors, are escalators and moving walks with a multiplicity of treading units or traveling platform pallets which are connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they walk on the pavement pallets in the same direction of movement as the driving devices drive or move.
- the tread units form escalator steps, hereafter referred to as steps, and for ride surfaces, the tread units form pavement pallets, hereafter referred to as pallets.
- Escalators overcome with relatively large inclination larger height differences as whole floors. Moving walkways, on the other hand, run horizontally or slightly at an angle, but generally with lower angles of inclination than escalators.
- such driving devices include drive trains, which are designed as stepped or pallet chains.
- drive trains are driven to move the steps or pallets in the conveying direction, and they are provided according to the prior art at equal intervals with so-called rollers.
- rollers These casters travel along dedicated or dedicated lanes Tracks.
- the drive trains run with the rollers around deflection wheels (eg sprockets) and thus make a change of direction.
- deflection wheels eg sprockets
- sliding elements can be used. The sliding elements or the
- Rollers are attached directly to a step chain or pallet chain that serves as the drive train, as described above.
- step or pallet chains including the sliding or rolling elements attached thereto, two further rollers are required per step or pallet, which are referred to as towing rollers and roll or drive along separate guide rails.
- the stages or pallets have been relatively expensive to manufacture or to pour and also expensive, since they must be very stable and torsionally rigid.
- the steps or pallets must be made very accurately to ensure a smooth, smooth running.
- An essential element of the steps or the pallets are the lateral cheeks or step cheeks, which have an essential supporting function. So far, step cheeks or cheeks are typically made of aluminum, which leads to a low weight, but brings high costs, since the molds or die casting molds are very expensive.
- partially step cheeks or cheeks are used, which are screwed together from several different sheet metal parts and different castings or pressed parts. These cheeks or cheeks are usually about twice as heavy as an aluminum (stepped) cheek.
- JP 2004/292106 A describes a stage for a
- Cheek eye can be interpreted. However, this circle is not designated and not explained in the description. In any case, the location of the circle excludes that a chain pin axis can be stored there.
- JP 01308388 A and equivalent GB 2216825 A show in FIG. 1 a step with side cheeks which have a two-dimensional shape and are designed without a peripheral edge.
- This formed of thick material side cheeks store in the usual way chain pin axes and tow roller axles.
- Fig. 18 side cheeks can be seen, which are formed of thin sheet with partially circumferential edge. However, these side cheeks have no eyes that could serve for the storage of chain pin axles or tow roller axles. These axles are obviously stored on more stable components that need to be connected to these cheeks.
- DD 69443 relates to a step for escalators, in which side cheeks are integrally connected to a front part.
- the front part is covered by a setting element.
- a tread element covering the step has a bend which closes off the step on the side opposite the setting element.
- the front part and the cheeks are flat, in which no eyes are provided for receiving axles. Again, the axes are probably stored in more stable components that need to be connected to the cheeks.
- the object of the invention is therefore to
- stage cheek or cheeks for a level or range of the type mentioned, but still satisfies all requirements or requirements profiles and allows a smooth, smooth running, is not prone to failure and a long life or long service life guaranteed.
- the cheeks or step cheeks should not be much heavier than the standard aluminum (stages) cheeks;
- Step cheeks or cheeks according to the invention are specially designed for use in a driving device which have a plurality of steps or pallets, each step or pallet having two lateral step cheeks or cheeks which are substantially perpendicular to a tread element or a tread surface and in one Stage also to a setting element or a setting surface or riser. Between the two lateral step cheeks or cheeks according to the invention, each step or pallet having two lateral step cheeks or cheeks which are substantially perpendicular to a tread element or a tread surface and in one Stage also to a setting element or a setting surface or riser. Between the two lateral
- Step cheeks or cheeks can of course also be provided middle step cheeks or cheeks.
- the step cheek or cheek consists of a one-piece, deep-drawn sheet metal, wherein the sheet has a three-dimensional shape with an at least partially encircling board.
- the step cheek or cheek on a stepped eye or pallet eye, which by Deep drawing is formed.
- the stepped eye or pallet eye of the step cheek or cheek is enclosed or surrounded by the sheet or steel sheet or NIROSTA sheet.
- the step cheek or cheek comprises with the step eye or pallet eye a chain pin axis of a chain or conveyor chain.
- An inventive driving device has at least one such step or pallet.
