Problems solved by technology

[0004] However, since one coil spring bears all the load received by one main rope, the coil spring will be enlarged
In addition, since it is necessary to secure a space for arranging the coil springs under the upper frame, the height dimension of the entire car becomes larger
Therefore, the miniaturization of the entire hoistway cannot be realized

Embodiment approach 1

[0020] figure 1 It is a perspective view showing a car of the elevator apparatus according to Embodiment 1 of the present invention. also, figure 2 yes means figure 1 Longitudinal sectional view of the car in . In the drawing, a car 1 and a counterweight (not shown) are suspended in the hoistway by a plurality of (three in this example) ropes 2 as suspension units. Each rope 2 is wound around a driving sheave (not shown) of a hoisting machine provided at the upper part of the hoistway. The car 1 and the counterweight move up and down in the hoistway through the rotation of the driving sheave. When the car 1 and the counterweight go up and down in the hoistway, the car 1 is guided by a pair of car guide rails (not shown), and the counterweight is guided by a pair of car guide rails (not shown). Guided by a pair of counterweight rails (not shown).

[0021] An installation base 3 is fixed on the top of the car 1 . A plurality of (three in this example) hook-and-snap assemb...

Embodiment approach 2

[0060] Figure 7 It is a longitudinal sectional view showing an elevator apparatus according to Embodiment 2 of the present invention. In the drawing, a pair of car guide rails 61 and a pair of counterweight guide rails (not shown) are provided in the hoistway. The car 1 is arranged between the respective car guide rails 61, and the counterweight 62 is arranged between the respective counterweight guide rails. The car 1 and the counterweight 62 are raised and lowered in the hoistway by the driving force of the traction machine 63 installed in the upper part of the hoistway. When the car 1 and the counterweight 62 are raised and lowered, the car 1 is guided by the car guide rails 61, and the counterweight 62 is guided by the counterweight guide rails.

[0061] The car 1 and the counterweight 62 are suspended by a plurality (three in this example) of ropes (suspension unit) 2 . A plurality of support beams 64 are fixed to the upper part in the hoistway. The support beam 64 s...

Abstract

Amount is fixed to an upper port ion of a car. The mount includes a pair of receiving portions arranged at an interval in a horizontal direction. Further, a cleat device is held on the mount. The cleat device includes: a hanger member including a pair of opposed portions individually inserted below the respective receiving portions, the hanger member being capable of being displaced in an up and down direction with respect to the mount; a pair of urging bodies individually arranged between the opposed portions and the receiving portions, the urging bodies urging the opposed portions and the receiving portions in such a direction as to resist displacement of the opposed portions and the receiving portions in a mutually approaching direction thereof; and a shackle arranged between the receiving portions and connected to the hanger member. The car is suspended by suspension means connected to the shackle.

Description

technical field [0001] The present invention relates to, for example, an elevator apparatus having a car suspended by main ropes or the like. Background technique [0002] In a conventional elevator system, a rod-shaped rope shackle (shackle, U-hook) is connected to an end of a main rope suspending a car to perform terminal processing of the main rope. The rope hook cover passes through the upper frame of the car along the up and down direction. A spring seat plate is provided on the portion of the rope hook sheath protruding downward from the upper frame. A coil spring is disposed between the spring seat plate and the upper frame, and the rope hook passes through the inner side of the coil spring. The main rope bears the load of the car through the coil spring, the spring seat plate and the rope hook. In this way, the car is suspended by the main ropes (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-355475 [0004] However, since...
