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 prevent transverse oscillation of a riding cage by absorbing a transverse fluctuating load component caused by curving a rail for guiding the riding cage of an elevator. CONSTITUTION:In a guide device 4, a guide piece brought into contact with a rail is supported by a spring. Electromagnets 12A, 12B for attracting the rail 3 are provided in a guide piece supporting member 7 which is rotatably supported to a guide piece bed 8 by a pin 9. Further, the guide device 4 is provided with a control unit not shown in the drawing, that is, sensor not shown in the drawing for detecting displacement of the guide piece supporting member 7 by distortion of the rail 3 at the time of lifting a riding cage 2 and a controller for controlling an excitation condition of the electromagnets 12A, 12B, for instance, direction and intensity of a current so as to eliminate this detected displacement. In this way, a transverse fluctuating load component by curving the rail for guiding the riding cage is absorbed by elasticity of the guide piece and prevented from being transmitted the riding cage, and an elevator having a comfortable feeling to ride with no transverse oscillation can be obtained.

摘要： PURPOSE: To easily manufacture installation brackets in a constant shape up to the rope allowable maximum number by constituting them form installation brackets to sub beams and shaft brackets directly to support a shaft of a deflector wheel. CONSTITUTION: A machine beam 4, a sub beam 6, a deflector wheel 13 and shafts 14 and 16 are the same as the conventional ones. An installation bracket 20 has height slightly lower than height between upper and lower flanges of the sub beam 6 and it is molded by bending a plate into a hat shape. The installation bracket 20 is fixed on a web 6b of the sub beam 6 with its hat shaped protruded part 20a part by an installation bolt 20c, and a shaft bracket 19 is fixed on a hat shaped flange part by an installation bolt 19a. Additionally, the installation bracket 20 is placed on the lower flange 6a of the sub beam 6 and made contact with it, and an upper side of the installation bracket 20 is constituted so as not to make contact with the upper flange of the sub beam 6. Additionally, plate thickness t2 to the installation bracket 20 can be thin, and for example, 6-9mm is the most favourable.

CONSTITUTION:In such a case that three doors, that is, a high speed door 1A, a middle speed door 3B and a low speed door 3C are linked one another and accordingly, they are opened and closed with displacement ratios of 3:2:1, an arm 20 is fastened by a bolt to a door hanger 2c projected from the upper part of the low speed door 1C, and a rope type link mechanism 8 is provided to the arm 8 so that the middle speed door 1B and the low speed door 1C are opened closed with a displacement ratio of 2:1. A pair of sheaves 14 are journalled to opposite ends of the arm fixed to the low speed door 1C at the front side surface, and are wound thereon with a linking rope 15 which is also wound on a stationary sheave 16 journalled to an hanger casing, so as to constitute a rope type link mechanism 9 in which the high speed door 1A and the low speed door 1C are linked together with a displacement ratio of 3:1.

摘要： PURPOSE:To provide an economical device of simplified constitution by detecting the pressure of a cylinder when a car sinks, and supplying pressure oil to the cylinder according to the pressure detected. CONSTITUTION:If the load of a car 1 is increased with a passenger or cargo getting into the car, oil in a cylinder 2 is compressed and pressure within the cylinder is built up. Therefore pressure within a pilot pressure chamber 19 is built up but pressure within a pilot pressure chamber 20 is not built up, so a three-port switching valve 6 is moved in the direction in which it pushes a spring 16, and then oil discharged from a sub-pump 4 thrusts up a check valve 8 and is supplied into the cylinder 2, whereby the car is positioned. When a car position detector 17 detects that the car has returned to its initial position, a solenoid switching valve 7 is operated once to equalize pressures within the two pilot pressure chambers 19, 20 so as to return the three-port switching valve 6 to its initial position. Therefore, the oil discharged from the sub-pump 4 flows back into a tank and positioning of the car is completed.

摘要： PURPOSE: To reduce the number of materials and to reduce time required for welding work by integrally molding by bending a plate for an installation part to a sub beam in a roughly square shape, building with bending a plate into a roughly-U-shaped-molded article to a speed reducer installation part and fixing both of them by spot welding. CONSTITUTION: A frame body 17a integrally molding by bending a plate for a member to connect a sub beam and a member to install a speed reducer in a roughly U shape is provided. Thereafter, a reinforcing member 17b molded by bending a plate into a roughly hat shape is provided to install the speed reducer. An integrated machine base 17 is provided by combining this frame body 17a and the reinforcing member 17b and spot welding them on an mating surface 17Q and a 17r part. It is possible to reduce the members by making the two members of the U shaped article integrally molding by bending a plate and the hat shaped-article molded by bending a plate, to reduce welding time by integrating both of them by spot welding and to eliminate welding distortion correction work.
