Description

本発明は、機械室が無い、いわゆる機械式レスエレベーター装置に関するものである。   The present invention relates to a so-called mechanical-less elevator apparatus having no machine room.

機械室が無い、いわゆる機械式レスエレベーター装置にあって、従来、巻上機を昇降路壁自体の内部に配置し、トラクションシーブのみをかごと昇降路壁の間に配置して省スペース化を図ったものが提案されている（例えば、特許文献１参照）。   In a so-called mechanical-less elevator device that does not have a machine room, a hoisting machine has conventionally been arranged inside the hoistway wall itself, and only the traction sheave is placed between the car and the hoistway wall to save space. What has been proposed has been proposed (see, for example, Patent Document 1).

また、一般的なエレベーター装置にあっては、機器を設置可能な昇降路有効寸法は、建屋の梁、昇降路内に立設される立柱などで昇降路壁に凹凸がある場合、最も内側、すなわち、かご側に位置する凸部が基準となる。   Also, in general elevator equipment, the effective dimension of the hoistway where the equipment can be installed is the innermost side when the hoistway wall is uneven due to the beam of the building, the standing pillar standing in the hoistway, etc. That is, the convex portion located on the car side serves as a reference.

特許２９９２２１９（段落番号００１０〜００１３、図２）Patent 29922219 (paragraph numbers 0010 to 0013, FIG. 2)

しかしながら、前述したエレベーター装置では、昇降路壁に、専用に形成した開口部へ巻上機を配置するため、その部分の昇降路壁の強度が不足し、したがって、開口部周囲に特別な補強を施す必要があった。また、巻上機を点検するために昇降路外に通じる点検用ドア、この点検用ドアにいたる経路、及び、巻上機を点検するためのスペース等が必要となり、昇降路周囲の設計レイアウトに制限を課すとともに、コストの向上を招くという問題があった。   However, in the elevator apparatus described above, the hoisting machine is disposed in the dedicated opening formed on the hoistway wall, so that the strength of the hoistway wall in that portion is insufficient, and therefore special reinforcement is provided around the opening. It was necessary to apply. In addition, an inspection door that leads to the outside of the hoistway to inspect the hoisting machine, a route to the inspection door, and a space for inspecting the hoisting machine are required. There was a problem of imposing restrictions and increasing costs.

本発明は、前述した従来技術における実状からなされたもので、その目的は、昇降路壁に巻上機を設置するための特別なスペースを要することなく、省スペース化を図ることのできるエレベーター装置を提供することにある。   The present invention has been made from the above-described actual state of the prior art, and its purpose is an elevator device that can save space without requiring a special space for installing the hoisting machine on the hoistway wall.
