| Disclosed herein is a side safety device for an escalator which is operated in such a way that a plurality of stairs circulates. The side safety device includes a side safety plate (100) which is coupled to each of side surfaces of each of the stairs (2) at a position adjacent to a vertical plate (2b) of the stair. The side safety plate has a triangular shape and protrudes forwards from the vertical plate. The side safety plate includes a bottom side (104) which extends parallel to a step board (2a) of the stair in a direction away from the stair, and a hypotenuse (106) which extends at a predetermined inclination so as to meet the bottom side. The inclination of the hypotenuse is substantially equal to an inclination of an inclined section of the escalator. | ||||||

| A braking apparatus and method for an escalator or moving walkway are provided. The braking apparatus may include a braking element, a linearly controllable solenoid assembly, a biasing mechanism, and a control device. The braking element may be adapted to engage a brake drum or brake disk on a drive shaft of the escalator or moving walkway. The linearly controllable solenoid assembly may include a brake coil and an elongated member. The elongated member may be moveable linearly along an axis and the braking element may be coupled to the elongated member. The biasing mechanism may be arranged to bias the elongated member in a first direction along the axis to increase a torque applied to the drive shaft by the braking element. The control device may be configured to modulate a current to the brake coil based on at least one measured parameter associated with an operating condition of the escalator or moving walkway, whereby the elongated member is biased in a second direction along the axis opposite the first direction to decrease the torque applied to the drive shaft by the braking element. | ||||||

| This invention relates to a braking device (10) for a passenger conveyor comprising at least one movable part (12). The braking device (10) comprises a braking element (18) having a braking portion (34) engageable with the movable part (12) of the passenger conveyor. The braking element (18) is movable in a first direction into a position in which the braking portion (34) engages with said movable part (12) of the passenger conveyor. The braking element (18), in a state in which the braking portion (34) engages with the movable part (12) of the passenger conveyor, is movable in a second direction from a position of initial engagement of the braking portion (34) into a braking position of the braking element (18). The movement in the second direction is driven by movement of the movable part (12) of the passenger conveyor. | ||||||
| 244 | Escalator braking with multiple deceleration rates | US10886726 | 2004-07-09 | US06971496B1 | 2005-12-06 | Thomas Nurnberg; Yilmaz Ozgur Cantez |
| A braking system for an escalator having multiple rates of deceleration. When electrical protective devices (EPD) indicate that the escalator should be stopped, the main controller makes a determination as to whether the maximum rate of deceleration should be applied or the lower rate of deceleration. The brake is then controlled according to this determination to prevent a sudden stopping of the escalator when it is not necessary. The EPDs may be divided into two or more groups for different rates of deceleration. A provision may be made for multiple signals at once. If the main controller fails to provide a deceleration rate, the braking controller automatically defaults to the maximum rate. This system may also be used with moving walkways or other conveyors. | ||||||

| The invention relates to a method for load-independently braking the step or pallet belt of an escalator or a moving walkway. According to said method, the activation of at least one safety element triggers at least one frequency converter in such a way as to activate a time-dependent braking ramp, said frequency converter interacting with the drive motor. The braking ramp then slows down the step or pallet belt to 0 m/s with essentially constant deceleration. | ||||||

| 247 | Indicator to show whether a switch has opened | US798108 | 1977-05-18 | US4176350A | 1979-11-27 | Billy J. Patterson |
| An indicator is provided for use in a machine, such as an escalator, having a multiplicity of normally closed switches which act to turn off the machine in the event of a machine malfunction, unsafe condition or an inappropriate switch placement. The switches are capable of reclosing but not restarting the machine. The indicator shows which of the switches caused the machine to stop thereby performing a troubleshooting function to allow a repairman to determine immediately which of the various machine systems caused the malfunction or unsafe condition. | ||||||
| 248 | Load dependent acting brake for conveyor devices | US51860474 | 1974-10-29 | US3927738A | 1975-12-23 | ERNST WERNER |
| A load dependent acting brake arrangement for conveyor devices composed of a brake disk secured to a drive shaft of the conveyor device, at least one brake jaw mounted at brake lever means and capable of being pressed under the action of brake spring means at the brake disk, said brake jaw being connected via a brake rod with a brake vent device, wherein in the switched-in state for venting the brake a pneumatic force opposing the force direction of the brake spring means is exerted upon the brake lever means and in the switched-off state the brake lever means is pressed by the brake spring means into the brake closing position. A mechanically acting deceleration feeler device is effective at the brake lever means and an adjustment lever acts via a prestressed spring at the brake rod and which adjustment lever moves through a path proportional to the deceleration occurring at the drive shaft of the conveyor device in the sense of reducing the braking force exerted by the brake jaw upon the brake disk.

| In an electrically operated road, such as an escalator, a braking force for stopping the electrically operated road is changed according to whether the running direction is upwardly or downwardly, so that the braking deceleration of the road during emergency stopping of operations will become independent of the running direction of the electrically operated road.

| 250 | Load-dependent braking device for conveying systems | US38197673 | 1973-07-23 | US3866725A | 1975-02-18 | GREUTTER WILFRIED |
| A load-dependent braking device for conveying systems having a primary brake with a fixedly adjusted braking moment and a secondary brake with variable braking moment, the braking moment of the secondary brake being adjusted in dependence on the loading moment acting upon a drive device or machine for the attainment of a braking deceleration or retardation independent of load. A rotatable brake part of the primary brake is rigidly connected with a fixed brake part of the secondary brake. A rotatable brake part of the secondary brake, which can be pressed by brake linings or pads against the fixed brake part through the action of spring pressure, is raised or lifted-off as a function of the change of speed occurring during the braking of the drive machine by a rod or linkage arrangement pressed by means of spring force against a setting cam. The setting cam is arranged on a flywheel or inertial disk mounted to be freely rotatable upon a drive shaft of the drive device and actuates the rod arrangement in proportion to the angle of displacement between the flywheel disk and the drive shaft in opposition to the spring force.

| A spring applied, electrically released brake illustrated as applied to escalators wherein the braking apparatus applies a first braking force sufficient to provide a predetermined deceleration under no load conditions. After a time delay, a second braking force is applied which when combined with the first braking force is sufficient to provide said predetermined deceleration under full load conditions. In emergency situations, when a safety circuit is interrupted, both braking forces are applied simultaneously to produce minimum stopping time.
