BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to elevators, and more particularly to safety-related equipment therefor.

[0002]

2. Description of the Related Art Conventionally, mechanical equipment for a drive machine (a hoisting machine) for raising and lowering an elevator car has been installed in a machine room provided separately from an elevator hoistway. However, in recent years, a so-called machine room-less type, in which a machine room which is conventionally provided in a machine room is arranged in a pit without separately providing a machine room, has become widespread. In the case of this type, when performing work in the pit such as inspection work, work is often performed with the hall door on the lowest floor open. For this reason, when working in the pit, a safety fence is set up in front of the hall entrance on the bottom floor so that users cannot approach it.

[0003]

[Problems to be Solved by the Invention] In many cases, the building where the elevator is installed does not have a place for the safety fence,
The workers carried it from the sales office or the management center, installed it, and brought it back after the work was completed, and the work efficiency was poor.

The present invention has been made in consideration of the above-mentioned problems, and makes it possible to prevent a worker from carrying a safety fence during work in a pit from a management center or the like, and to make it easily available. The purpose is to

[0005]

In order to solve the above-mentioned problems, the elevator according to the present invention has a toe guard, which is conventionally provided in the elevator, removable. This can be removed and used as a safety fence during pit work.

[0006] According to this, the worker can procure the safety fence at the site and does not have to carry it to the site.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings. Figure 1
It is a figure which shows the lower part by the side of the entrance of the cab 10 of an elevator, especially the cab 10. The car room 10 includes a car floor 12 and a car panel 14 erected on the car floor 12, and the hall side is open to form an entrance 16. Entrance 16 is a basket sill 1
It is opened and closed by a car door 20 which slides on the car 8.

A toe guard 22, which is a plate-like member extending downward from the entrance 16, is attached to a portion of the car floor 12 below the entrance 16. The Tougard is equipped with an elevator, and when there is a step between the car floor and the landing floor,
This protects the elevator user's toes, such as the toes, from entering below the car threshold 18. Similarly, when a step is generated, the article is prevented from falling into the hoistway. The toe guard 22 connects two plate-like plates 24 with a hinge 26 and is attached to the car floor 12 in a folded state.

The toe guard 22 is mounted by mounting screws 2
8 is performed. The toe guard 22 is provided with a mounting hole 30 having a shape in which a circular hole and a groove are combined as shown in the drawing. The circular part of the mounting hole 30 has a mounting screw 28
Has a diameter that allows the head part of the
The groove portion is wider than the neck portion of the mounting screw 28 and narrower than the head portion. With this structure, the toe guard 2 can be installed without completely removing the mounting screw 28 from the screw hole.
2 can be attached and detached.

FIG. 2 shows the toe guard 22 removed from the car floor 12. FIG. 3 shows a state in which the toe guard 22 including the two plates 24 is opened. In this state, as shown in FIG. 4, it stands on the floor of the hall entrance 32 on the bottom floor and is used as a safety fence. The two plates 24 stand at an angle and open.
