ある。(b) Description of Prior Art As shown in FIG. 1, a conventional drive device uses a car and a counterweight, which are tied together with a rope, and the car is raised and lowered by a hoist via a sheave. Another method, as shown in FIG. 2, is to raise and lower the car by using a winding drum system in which a rope is fixed to the top of the car and wound around a drum via a deflector wheel.

欠点がある。The disadvantages of these conventional systems are that a counterweight is required, and a bracket for fixing the counterweight rail is also required, and the hoistway must be wide enough to provide space for the counterweight. Additionally, the main machine room is located above the top floor, increasing the height of the building and causing problems such as sunlight rights. The winding drum type has the disadvantage that the drum width of the winding drum is very large to wind the rope, which limits the size of the motor, and it also takes up space in the machine room. be.

又、ロープを巻き取る方式のだめ最上階停止の１まのと
きはロープはドラムに巻きとられたままとなり曲げの状
態がロープ全体にかかりロープの寿命を短かくする欠点
もある。In addition, since the method of winding the rope is not available, the rope remains wound around the drum when the rope is stopped at the top floor, and the entire rope is bent, which shortens the life of the rope.

目的としている。(CJ Purpose of the Invention The present invention is a low-cost mechanical elevator that is suitable for residential elevators with a relatively small number of floors, does not have a counterweight, has a small machine room, and therefore requires a small hoistway. It is intended to.

。(d) Summary of the Invention A rope is attached to the upper part of the car and the lower part of the car, and a sheave of a hoist is wound around the middle of the rope to drive the car, thereby raising and lowering the car.

Attach the rope 4 to the upper part of the car 5, and run the rope 4 through the uppermost car 3 to the machine room on the lowest floor, through the guide sheave 7, and through the main sheave 2 of the hoist 9. Tension is applied, a rope is fixed to the lower part of the car passing through the sheave 8, and the heel 5 is raised and lowered by driving the main sheave 2 of the hoist 9.

（ｆ）　発明の作用、効果本発明により従来つり合いおもりをもちいていた方式と

がいらないため小さくできる長所がある。(f) Functions and Effects of the Invention Unlike the conventional method using a counterweight, the present invention eliminates the need for a counterweight, brackets to hold it, rails, rail installation work, etc., and also because the machine room is located below. There is no need to worry about problems such as sunlight rights in residential areas, and there is an advantage that the hoistway can be made smaller as there is no need for space to raise and lower balancing weights.

巻胴式エレベータと比較して、巻胴用のドラムが必要な
くなり、今までのシーブ［１〕があれば良゛く・モータ
の寸法などの制限が緩和され機械室スペースが広く使え
る長所がある。Compared to a winding drum type elevator, there is no need for a drum for the winding drum, all you need is the conventional sheave [1], and restrictions on motor dimensions are relaxed, allowing for more space in the machine room. .

又、巻軸式のようにロープをいつまでも巻きつけておく
必要ないためロープ寿命の面からもよ・い効果がある。In addition, unlike the winding type, there is no need to keep the rope wrapped forever, which has a good effect in terms of rope life.

Claims

[Claims]

A car runs up and down the hoistway, and a plurality of sheaves are attached to the hoistway to suspend and guide the rope, which consists of a rope tied at each end to the top and bottom of the car, and a main sheave around which the rope is wound in the middle of the rope. An elevator, characterized in that the car is moved up and down by driving the main sheave.
