Problems solved by technology

[0006] In the technology described in the above-mentioned patent document 1, a telescopic pedal is provided at the bottom of the car, and its basic structure is: a part of the guardrail arranged on the entrance and exit side of the elevator road under the car can be opened and closed, and the guardrail and the folding The ladders (pedals) of the type are set independently, and this structure requires a lot of space under the car. Therefore, when the operator performs maintenance work in the pit, it will not only cause obstacles, but also cause accidental collisions with these components. In addition, there are also concerns that these components will interfere with other equipment installed in the liftway and cause damage to other equipment. Therefore, there are many problems with its structure.

Abstract

The invention provides an elevator compartment. Even when a bottom pit ladder is arranged, space occupation under the compartment can be reduced and no barriers are caused to maintenance work and worries of damages to other equipment in an elevating path can be prevented. In the elevator compartment, during the installation of a guardrail (5), a plurality of guardrail sheets (7) and a rope (6) integrated form a bottom pit ladder used when an operator works between the bottom pit and the elevator riding position; normally, each guardrail sheets (7) are accommodated into a notch part (5a) of the guardrail (5); during the maintenance work, the guardrail sheets can be detached, pulled out and expanded and remained at a dangling state toward the bottom pit of the elevating path; and the operator can passes through the notch part (5a) of the guardrail (5) and holds a holding part (16) and the rope (6) in the elevating path to make each guardrail sheets (7) pedals (pedal steps). Therefore, the operator can smoothly and safely come in and out; interval arrangements of a pair of hooks (4) combined with one end of the rope (6) and the guardrail (5) enable the operator to easily come in and out.

Description

technical field [0001] The present invention relates to an elevator passenger compartment comprising a pit ladder, which is used by operators when entering and exiting between the bottom pit at the lowest part of the elevator hoistway and the elevator place. Background technique [0002] Generally, in an elevator, in order to perform maintenance work such as inspection or repair, an operator must enter and exit between a pit provided at the lowest part of an elevator hoistway and an elevator boarding place. As a well-known technology that makes it easy for workers to enter and exit when performing this kind of work, a kind of "elevator car" can be exemplified. This "elevator car" is provided with a folding ladder at the bottom of the car. The ladder is elongated and used to go in and out between the elevator place and the bottom pit (with reference to this patent document 1).
