| 201 | BRAKING SYSTEM FOR ESCALATORS AND MOVING WALKWAYS | US13712573 | 2012-12-12 | US20130153362A1 | 2013-06-20 | Miguel Angel GONZALEZ ALEMANY; Alberto FLOREZ CASTRO; Jose OJEDA ARENAS; Eva RODRIGUEZ RODRIGUEZ; Eduardo MORAN GARCIA; Jose MENDIOLAGOITIA JULIANA |
| A braking system for escalators and moving walkways, includes a braking device (3) with a main brake (30) of the type which is released when there is no voltage in its electric activator, and an auxiliary brake (31) of the type which is closed when there is no voltage in its electric activator. A controller (1) controls the braking device (3), prepared for obtaining the load of the escalator or moving walkway, and calculates the braking torque required for each braking device (3) depending on the load and activating the braking device (3) for obtaining the corresponding torque while braking when a braking command is received. The auxiliary brake is activated (32) for taking the escalators or moving walkway to a safe position when there is a system failure. | ||||||
| 202 | ESCALATOR DUAL SOLENOID MAIN DRIVE SHAFT BRAKE | US13320957 | 2009-06-16 | US20120073933A1 | 2012-03-29 | Alois Senger |
| A main drive shaft brake for a passenger conveyor includes a braking element, an actuator, and a counter-actuator. The actuator is de-energized to release the braking element and halt operation of the passenger conveyor during an abnormal or emergency condition. An energized counter-actuator permits release of the braking element but, when de-energized, inhibits release of the braking element by the actuator to prevent unintentional release of the braking element caused by, for example, an accidental loss of power to the actuator. | ||||||

| The invention concerns a method and a system for ensuring the operation of the safety circuit of an elevator or escalator, said safety circuit containing safety contacts (10, 12, 14) connected in series with a contactor (16). In the method, the largest bypass current coming to the contactor in a fault situation is defined, a testing device (202) is connected in series with the safety circuit, said testing device containing at least one resistor (26), which is used to produce a desired test current that is larger than the largest bypass current, and the neutral point (18) of the safety circuit is shifted if the contactor (16) remains energized by the aforesaid test current. | ||||||

| An escalator drive assembly (30) includes a sensor that facilitates detecting when the normal drive assembly operation is interrupted, such that a brake should be activated. In one example, a sensor member (40) in the form of a flange (42) is associated with a drive pulley (34) and normally rotates in unison with the drive pulley. When there is a failure in the normal operation of the drive mechanism, however, there is a resulting relative movement between the sensor member (40) and the drive pulley (34). Such relative motion preferably activates a switch (80) that provides a signal that indicates a failure of the normal operation of the drive mechanism (30). Another example sensor includes a sensor member (202, 212) that engages a drive belt (35). If the belt (35) breaks, the sensor member (202, 212) moves to provide an indication of the broken belt condition. Various braking application modes are possible using the invention. | ||||||
| 205 | Escalator caliper brake assembly with adjustable braking torque | US837171 | 1992-02-18 | US5277278A | 1994-01-11 | Martin Mehlert; Wolfgang Michalik |
| An escalator is provided with a caliper disc brake for stopping movement of the steps in cases of emergency. The disc is mounted on the main drive sprocket shaft, and the caliper is normally held away from the disc. When power is removed from the drive, the caliper is set on the disc to stop further movement of the steps. The braking torque of the brake assembly is adjustable to allow use of one basic assembly with escalators having different rises. The adjustment is accomplished by moving the center of gravity of the brake pads toward or away from the pivot axis of the brake lever. The brake can also be finely tuned at installation to provide an optimum stopping distance and time so that a too abrupt stop is avoided. | ||||||

| An improved keyswitch circuit for an escalator or moving walkway senses the normal (center or lateral) position of the keyswitch and, if the keyswitch does not return to its normal position after a selected event such as a selected normal starting interval, then the safety circuit is opened and the escalator or moving walk is stopped; the escalator or moving walkway can be restarted only after first returning the keyswitch to its normal position. | ||||||

| A passenger conveyor, such as an escalator or a moving walkway, in which a device for transmitting a change of direction of the movement of treadboards to a passenger by changing the passenger's sense of touch is provided in the vicinity of a boundary between a horizontal path and an inclined path. With this construction, a level difference between the adjacent treadboards is produced when the treadboard moves into the inclined path, thereby preventing the passenger from accidentally falling down. | ||||||
| 208 | Escalator step buffer | US368476 | 1989-06-19 | US4926981A | 1990-05-22 | Klaus Bruehl; Dietmar Thaler |
| An hydraulic buffer or brake is provided on an escalator to stop movement of the steps in case power is interrupted, or if a safety device is activated. The braking action occurs in parallel to the inclination of the step chain. The braking action occurs in several stages so that a maximum time delay between initiation of the device and stopping of the steps can be achieved. In the first stage, the braking force is more solely applied, so that the first stage can affect a stopping of an empty escalator when completed. In the second stage the braking force is more quickly applied, so that the first and second stages can affect a stopping of a heavily loaded escalator in concert in the same maximum deceleration as the first stage can, when completed stop the lightly loaded escalator. | ||||||

| 220 | METHOD FOR MEASURING AN ESCALATOR AND A HOLDING DEVICE AND SLIDES FOR A MEASURING PROBE IN ORDER TO MEASURE AN ESCALATOR | PCT/DE2004000905 | 2004-04-30 | WO2004096689A3 | 2005-07-28 | LYSEN HEINRICH; ECKER MATTHIAS; KONETSCHNY VOLKER; LEWIS SIMON; STROEL KLAUS |
| The invention relates to a method for measuring an escalator, whereby a measuring probe (28), which is configured in such a way as to determine the rotational angle of the probe around at least one spatially fixed or probe fixed axis (30, 32, 34, 45, 47), is disposed in a spatial relation on at least one of the steps (10, 10A, 10B) of the escalator. The escalator comprising the probe is displaced from a start position. The alterations of the rotational angle or the rotational angle of the probe around the at least one axis are detected during displacement of the escalator and the detected alterations of the rotational angle or the rotational angle of the probe around the at least one axis are evaluated in order to determine at least one geometric parameter of the escalator. | ||||||
