摘要： PROBLEM TO BE SOLVED: To block the fire and heat, and to improve the fireresisting performance with a simple structure with the low manufacturing cost, by providing the sections of the door covers with the almost projecting and recessed parts in such manner that they can be fitted with each other with a small gap, and the projecting and recessed parts are closely kept into contact with each other when the fire occurs at the landing side. SOLUTION: When the fire occurs at a landing 2 side, a temperature of a door stop part at a hoistway side, rises, and a door stop rubber 3D is melted and lost, the doors 3A, 3B are further closed by a thickness G2 by the closing force of a door closer. The door covers 6C and 6D are also closed to each other to reduce a gap corresponding to this motion, whereby the faces 6E, 6F of the door covers 6C, 6D are fitted with each other to be closely kept into contact with each other with the motion same as the gap G1. Whereby a hoistway side can be prevented from directly exposed to the fire at the landing 2 side, a rise in temperature at the hoistway side can be inhibited, and the eruption of fire to the hoistway side can be prevented. The heat-resisting performance can be improved with the low manufacturing cost, without adding the new components and without increasing the weight so much.

摘要： PURPOSE:To provide a door sill device for elevator which reduces travel noise generated when an elevator runs at high speed. CONSTITUTION:A clearance larger than 4cm, which is stipulated in the Building Standard Law and its enforcement act, is formed between a car door sill 13 on a car side and a landing door sill 12 on a landing side to suppress travel noise. When a car is landed, a movable door sill 5 is rotated to a position shown by a chain line through a link mechanism 11 interlocked with the opening and closing of a car door 1. By this, a clearance between the car door sill 13 and the landing door sill 12 is reduced to 4cm or below to maintain the safety of passengers.

摘要： PURPOSE:To smoothly make a lower down motion of a moving cable at the time of down-operation of a cage by providing constitution such that force of pulling downward the moving cable through a drive rope is given by a weight unit. CONSTITUTION:A drive rope 17 is link-wound on a pulley 18a, pivotally mounted to a carriage 10, to fix one end of the rope to a lift path 1 to connect the other end to a balance weight 7. A pulley 20 is pivotally mounted to a weight unit 19, and the guide rope 17 is link-wound onto the pulley 20 through guide pulleys 18b, 18c. In the case of a cage 6 in down-operation, fixed force always acts on the drive rope 17 by own weight of the weight unit 19 to apply suitable lower-down force to the carriage 10, and as a result, suitable lower-down force is given to a moving cable 14.

摘要： PROBLEM TO BE SOLVED: To provide an elevator having a means for individually grasping the deterioration state of synthetic fiber ropes for supporting load by parallel arrangement of the plural ropes, and determining the discarding time of each synthetic fiber rope. SOLUTION: In this elevator, a car 2 and a counterweight 3 are connected to each other by synthetic fiber ropes 1 of plural parallel arrangement, and the synthetic fiber ropes 1 are wrapped round sheaves 4 to be frictional-driven. This elevator is provided with a means for detecting the position of the car 2 in a hoistway, a means for detecting the position of the counterweight 3 in the hoistway, a means for individually calculating an increase in the elongation amount compared with the no-deteriorated state of each synthetic fiber rope 1, a means for individually recording the allowable limit of increase in the elongation amount of each synthetic fiber rope 1, and a means for individually judging whether the increase in the elongation amount of each synthetic fiber rope 1 is within the allowable limit or not. Thus, the replacement and discard time of the ropes can be individually determined so as to heighten the safety and reliability of mechanical system of the elevator. The progress of deterioration is automatically recorded and notified so as to achieve labor-saving of maintenance.
