Description

[Detailed description of the invention] This invention relates to an improvement of an elevator car frame.

First, a conventional elevator car frame will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is a vertical frame, 2 is a support frame placed inside this, 4 is a car floor supported by the support frame 2 via vibration isolating rubber 3, 4a is a floor plate of this, and 4b is a The side frames 4c are fixed to the underside of the floorboard 4a and are made of lipped channel steel with reinforcements placed between the side frames 4b.

That is, the reinforcing material 4c is attached to the floorboard 4a in the cross-sectional direction.
Since only one side of the cage is fixed to the cage, there is a problem in that the vibrations caused by resonance with the vibrations of the car frame are large and cause discomfort to passengers inside the car.

This invention aims to solve the above-mentioned drawbacks and to provide an elevator car frame that has less unpleasant vibrations and is highly durable.

An embodiment of this invention will be described below with reference to FIG.

In the figure, the same reference numerals as in FIGS. 1 to 3 indicate corresponding parts, and 4c is a reinforcing member made of steel having a chevron-shaped cross section, and both legs are welded to the lower surface of the floor plate 4a made of a steel plate.

Reference numeral 5 indicates a space in the cylindrical portion formed by the reinforcing material 4c and the floor plate 4a, and 6 indicates a through hole provided in the side frame 4b and communicating with the outside of the car floor 4 and the space 5, and a corresponding position of the space 5. There are separate settings for each.

That is, the reinforcing material 4c and the floor plate 4 form a closed cross-sectional shape in cross section.

Therefore, vibration of the reinforcing member 4c can be reduced and a car with good riding comfort can be obtained.

Further, since the through hole 6 is provided, a nozzle can be inserted into the through hole to spray paint the inner surface of the cavity 5 easily and sufficiently, and the corrosion resistance inside the cavity 5 can be improved.

FIG. 5 shows another embodiment of this invention. In the figure, the same reference numerals as in FIG. through-holes.

That is, the reinforcing material 4c is welded to the floor plate 4a in the same manner as shown in FIG.

Further, the inner surface of the cavity 5 can be painted as well as the through hole 6.

Therefore, although a detailed explanation will be omitted, it is clear that the same effect as the embodiment shown in FIG. 4 can be obtained in this embodiment as well.

As explained above, in this invention, the legs of the reinforcing material with a chevron-shaped cross section are welded to the floor surface, and the end faces of the reinforcing material are covered by the side frames to form a space closed at both ends. Since the floor is provided in at least one of the above-mentioned members and has a cylindrical part having a through hole that communicates with the inside and outside of the cavity, the vibration of the reinforcing material can be reduced and the riding comfort can be improved. Furthermore, the inner surface of the cylindrical portion can be easily painted through the through hole, thereby realizing a highly durable elevator frame.
