Definitions
- the invention relates to an escalator having a plurality of movable step segments, which run in line on four wheels, which are mounted at the four corners of each step segment, wherein the tread surface of each step segment is horizontal sloping at the front side transport and sloping back at the rear return transport.
- Step segments consist of several profiles which are articulated to each other, wherein both the front rollers / wheels of the step segments on a transport chain and the rear rollers / wheels of the step segments are attached to another transport chain.
- Escalator construction is technically complex and also has the disadvantage that conventional escalators also have that both the lower end (lower turning station) and in the upper end (upper turning station) a large height is required, so that installation of this escalator then not possible is, if in the lower and / or upper end area little height is available.
- the object of the invention is to an escalator of this kind so too
- each step segment is formed by a right-angled step plate of constant height, at each of whose four corners a wheel is mounted,
- the step segments are transported at a sloping tread from the two circulating transport chains on two oblique, rear, second raceways back.
- the lower turning station is so low in height that it can be accessed directly.
- the staircase is made with a composite of several carriers and on it arranged raceways and
- the two transport chains have chain links as rollers whose diameters are equal to the
- Diameters of the wheels of the step segments is.
- Runways are arranged in lateral cheeks of the escalator.
- Escalator the transport chains are deflected by sprockets.
- step segments are guided horizontally in the upper and lower end region of the escalator and in this case form with their treads a horizontal entry and exit surface. Safe transport and safe guidance of the individual
- Step segments are given when the back end of each step segment is chamfered at an angle equal to that of
- the stability of the escalator is significantly improved when the two side walls of the escalator are interconnected by U-shaped beams, which are at the same time terminations of the tread areas.
- Stepped segments are deflected so that a safe deflection movement of the individual stages segments is given.
- Figure 1 The escalator in the lower area
- Figure 2 the escalator in the upper area.
- the escalator has a plurality of step segments 1, each formed by a rectangular step plate consistently low height are.
- the top of the step segment forms a tread surface 3 and at each of the four corners, a wheel 2 is mounted, the axis of each of which lies below the tread surface 3.
- the front two wheels 2 a are each attached to a transport chain 4, which is formed by a roller chain with rollers 7.
- the rear two wheels 2b of the step segments 1 run on first inclined raceways 5 and are not attached to any chain.
- the step segments with their step plate and tread surface 3 are horizontal, while in the back
- Transport area D the step plates and treads 3 are inclined.
- the step segments 1 run in their oblique position with their four wheels 2a, 2b on the rear second raceways. 6
- the rear ends 15 of the step segments are beveled at an angle ⁇ corresponding to the pitch angle of the escalator, so that a secure guidance of the step segments is given to the first raceway 5.
- Both in the lower end area (lower turning station) A and in the upper end area (upper turning station) B run the two lateral
- Step segment 1 is deflected or turned over (turned).
- a cheek 8 On either side of the escalator is located in each case a cheek 8, which receive the transport chains and the raceways 5, 6.
- the cheeks 8 are connected to each other by U-shaped supports (not shown), which serve for stability and are also closures of the tread portions 19.
- Step segments (also referred to as "lower tread area” 19) become smaller in this lower tread area, as a result of which the foot / shoe of a user of the escalators can be clamped in.
- a horizontally movable slide is located in the lower tread area
- the treads are grooved on the surface and on the front and back side and the edges edged or rounded. They are connected to the supporting and pulling devices of the step link belt and correspond by means of the rear slopes with all
- Terminating devices may have breakthroughs, divisions, cuts or inclusions, etc., but not exceeding their basically flat, cuboid contour.
- the turning stations are equipped with the bearings for the stair scaffold, with the drive device for the step link belt and with the arranged in the shaft movable or immovable shut-off devices for personal and accident protection; further comprising means for the chain tension, for the deflection of the step link belt, for the inwardly bent roller conveyors and for the transitions of the step link belt at the connection points of the modules. They can be equipped with an additional drive with an additional drive shaft.
- the cover of the turning station is with a down in the
- the handrail is equipped below the handle area with a knob protection and can be provided with a disinfection device.
- the body may include devices for cleaning, for providing atmospheric pressure, cooling, heating and other protection and safety devices.
