20150251879 | ESCALATOR STEP AND ESCALATOR HAVING THEREOF - An escalator step includes: a tread that includes a body section wherein a plurality of convex sections, which are parallel in a travelling direction, are arranged in a width direction; a riser that is coupled at a rear end portion of the body section of the tread and on which a plurality of convex sections are arranged in a width direction, with troughs being formed between adjacent convex sections; and a shock absorbing cleat located in a notch formed in a corner portion where the riser and the tread are coupled together. On the shock absorbing cleat, a plurality of convex sections, arranged in a width direction and parallel to the travelling direction, rear end surfaces are flush with troughs of the riser, each of the convex sections of the shock absorbing cleat is shifted a half pitch from each of the convex sections of the riser. | 09-10-2015 |
20150136563 | ESCALATOR STEP AND ESCALATOR HAVING THEREOF - An escalator step includes a tread having a body section on which a plurality of convex sections are arranged in parallel, a riser connected to a rear end portion of the tread and having thereon a plurality of convex sections and a plurality of concave sections formed between the adjacent convex sections, and a shock absorbing cleat provided on a corner at which the riser and tread are connected to each other. The shock absorbing cleat includes a plurality of long convex sections which are arranged in parallel and a plurality of short convex sections which are arranged in parallel between the adjacent long convex sections. The shock absorbing cleat is formed of a polymeric material having a Young's modulus of 1000 MPa or less. | 05-21-2015 |
20140131141 | ELEVATOR OPERATION CONTROL METHOD AND OPERATION CONTROL DEVICE - The elevator operation control method according to the embodiment estimate the amount of shake of a long object which moves accompanying lifting and lowering of a passenger cage by way of simulation based on the amount of shake of a building in which an elevator is installed and current position information of the passenger cage of the elevator. The elevator operation control method change every second a physical model of the simulation according to the position of the running passenger cage, and simulate in real time the amount of shake of the long object from a current amount of shake of the building and position information of the running passenger cage. The elevator operation control method compare the amount of shake of the long object calculated by the simulation and a threshold, and perform a control operation according to the result. | 05-15-2014 |
20120298453 | VIBRATION DAMPING APPARATUS FOR ELEVATOR CAR - According to one embodiment, a vibration damping apparatus for an elevator car includes an engaging apparatus, an interlocking mechanism, and a friction generation mechanism. The engaging apparatus includes a pair of engaging vanes. A gap between the vanes is narrowed when the car door apparatus is opened. The interlocking mechanism includes a lock lever and an engaging body, is released by an action of the engaging vanes holding the engaging body, and interlocks the hall door apparatus with operation of the car door apparatus. The friction generation mechanism generates a frictional force between the engaging vanes and the engaging body for suppressing a vertical vibration of the car when the engaging vanes are in a state of holding the engaging body. | 11-29-2012 |
20090008216 | Passenger Conveyor - Provided is a passenger conveyor including a plurality of steps ( | 01-08-2009 |
20080277207 | Machine Room-Less Elevator - A machineroom-less elevator in which a counterweight is vertically moved behind a cage, with the cage and the counterweight being suspended in a jig back manner through a first and second diverting sheaves. In this machineroom-less elevator, a sufficiently large vertical stroke of the counterweight can be secured, while a durability of a hoist rope is improved. In addition, since no tensile difference is generated in respective parts of the hoist rope, vertical vibrations of the cage are prevented when the cage restarts a vertical movement. A traction sheave is disposed on one of right and left sidewalls of an elevator shaft. A first diverting sheave is disposed below and sufficiently apart from the traction sheave, and a second diverting sheave is disposed on a top of a rear wall of the elevator shaft. The traction sheave is disposed to be inclined relative to the sidewall such that a rotational axis thereof extends from the sidewall of the elevator shaft to the rear wall thereof, when viewed vertically from above. | 11-13-2008 |
20080207106 | Blower Controller For Elevator System - An elevator system includes a mode switch configured to select one of a plurality of operation modes based on a state of the elevator cage, and a blower controller configured to control a blower to adjust pressure inside an elevator cage according to the selected operation mode. | 08-28-2008 |
