摘要： PURPOSE: To obtain a tail cord which is suitably used for the electric power supply and signal transmission, between an elevator cage and a controller in the machine room of the elevator for the superhigh speed and a superhigh- storied building. CONSTITUTION: Each of the reinforcing wires 24a and 24b is constituted thicker than that in the ordinary case, in order to increasw the rigiduty so that the suspension width interval of a tail cord can be set large, and further, each of the blocks 21a and 21b of an electric power supply wires has a thick core wire, in order to assist the action for setting the suspension width interval of the tail cord large, together with the reinforcing wires 24a and 24b. In the electric power supply to a cage, the high voltage integral electric power supply method is adopted to reduce the supplied electric current, and the quantity of core wires can be reduced. Such the tall cord can be suspended at the position close to the center in the lateral direction of the cage, and the eccentric load in the lateral direction of the cage due to the weight of the tail cord can be reduced.

摘要： PURPOSE:To provide an end floor safety device for an elevator, suitable for long travel and high speed by attempting decrease of detecting numbers on the upper end floor and the lower end floor in a hoistway and labor saving for the attachment, and decreasing signal cables for connecting an elevating body to a machine room control panel. CONSTITUTION:In an end floor safety device 15 installed on a car 1 of an elevator, a detecting means for detecting respective optional positions on the upper end floor or on the lower end floor in a hoistway and a discriminating means 10 for discriminating whether the position is the upper end floor side or the lower end floor side are provided, and the detecting means is used for detection of the positions of the lower end floor and the upper end floor, and output signals of respective means 10 are logically combined with each other, so as to detect the positions of respective end floors. Accordingly, oscillation of an arm of an end floor safety device is generated on one side, thereby a mounting space on one side is not required. Moreover, a contact on one side and a cam device are not required. Thereby, the number of contact signal cables are decreased, and load to the elevating body is decreased, thereby stability of elevation can be attempted.

摘要： PURPOSE:To carry out the antenna switching without causing the interruption of reception by receiving periodically the data on the present position and the moving direction of an elevator cage and detecting the gap of a rectilinear wave source through the arithmetic processing. CONSTITUTION:The at a on the present position and the moving direction of an elevator cage 3 are processed by the program stored in an internal storage means ROM and periodically sent to a communication controller 12. A lose coupled radio transmitter device 13 converts the received data into the radio waves and then radiates them from a rectilinear wave source 20 via an impedance box 14. Meanwhile a controller 27 contained in the cage 3 periodically receives the radio signals and produces an antenna switching command to connect a lower antenna 24 to an elevator cage radio transmitter device 26 by the processing of the program stored in the internal ROM. Thus an antenna switching device 25 carries out an antenna switching. That is, the antenna reaching a gap of the source 20 is separated from the device 26 right before the held antenna actually reaches the gap.

摘要： PURPOSE:To provide an end floor safety device using contact type switches for position detection in a low speed region without the generation of contact noise in position detection in a high speed region by using contactles switches for position detection in the high speed regions provided near both end floors in an elevator shaft, and using the contact switches for position detection in low speed regions. CONSTITUTION:Ascent speed reducing command switches 1U-5U are disposed on the elevator shaft side near the uppermost floor through a fitting plate 5. The switches 1U, 2U put in action at high speed are to be contactless switches such as memory switches put in action by magnetic force, and the switches 3U-5U put in action at low speed are to be contact type switches such as alternate type switches. When a car 1 ascends and a normal speed reducing command device is not put in action, a drive unit 9 faces the switch 1U when the car 1 approaches the end floor, and the switch 1U outputs a speed reducing command. With further ascent, the switch 2U also outputs a command signal. The switches 30-5U are then brought into contact with an operating cam 8 and successively put in action to stop the car 1 safely at the end floor.

摘要： PURPOSE:To increase detection precision in regard to the vibration of a car even in a case in which the travel distance of an elevator becomes long and the speed of the elevator becomes high, by making a fitting space small, increasing the point number of position detection. CONSTITUTION:An operation cam is composed of inclined cams 5a-5c that have inclination in regard to a guide rail 2 and are arranged at positions where detection is desired, and parallel cams 6a-6c that are in parallel with the guide rail 2 connected to these inclined cams. In a case in which the switch drive roller arm 4 of an end floor safety device 3 is driven by coming into contact with the operation cam and being engaged with it, the roller arm 4 drives the switch at the positions of the above inclined cams 5a-5c, and the detection signals of the positions are outputted. As a result, position detection can be conducted with high precision at the vibration width of the necessary minimum.
