Description

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

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

In Figures 1 to 3, 1 is the hoistway, 2 is the hoistway 1
The machine room 3 provided above is a hoisting device installed in the machine room 2, and the drive of this hoisting device 3 moves the car room 5 and the counterweight 6 through the main rope 4.
is configured to move up and down within the hoistway 1.

The car room 5 has a car floor 8, a car room wall 9, and a ceiling 10 housed within a framework 7 connected to the main rope 4.
is equipped. The framework 7 has an upper beam 11 and a vertical column 12
The car floor 8 is fixed so as to be suspended. The car wall 9 is composed of a front wall 13, side walls 14, and wing walls 15. Normally, passengers in an elevator, whether they board the car 5 alone or in a large group, lean against the front wall 13 and side wall 14 after operating the push button 16a of the car operation panel 16. There are many.

In this case, as shown in FIG.
Even if it is deflected by a relatively large amount of deflection δ, there is a large margin between it and the counterweight 6, so the front wall 13
There is no risk that the front wall 13 will catch on or come into contact with the counterweight 6 if the passenger simply leans back. However, there is a seam 1 of the wall board material between the side wall 14 and the vertical column 12 located on the back side.
4b and the vertical reinforcing member 14a, and because it is desired to increase the floor area of the car room 5 as much as possible, the gap between the side wall 14 and the vertical column 12 is small. Therefore, when the passenger leans lightly on the side wall 14, the passenger immediately comes into contact with the vertical column 12 and speaks.

Therefore, the elevator car wall 9 has been constructed to have such rigidity that it does not bend significantly even when a passenger lightly leans on it, and that the side walls 14 do not come into contact with the vertical frame 12.

However, recently, in order to save energy, the car compartment 5
There is a need to reduce the weight of the front wall 13, side wall 14,
It has become necessary to reduce the weight of the wing walls 15. Reducing the weight of these walls 13 to 15 tends to immediately lead to a decrease in rigidity, and for the reasons mentioned above, it is not possible to increase the wall thickness by the amount of thinning of the wall plate material in order to increase the section modulus Z of the wall. It is necessary to accept a decrease in rigidity within the allowable limit.

Furthermore, to date, no processing technology has been found that would increase the rigidity of the cage walls by replacing the wall panel material with a new material. Therefore, it is desired to reduce the stiffness of the cage wall within an allowable limit and to reduce the weight of the cage.

This invention is an attempt to meet the above-mentioned demands, and is based on reinforcing members provided horizontally on the back side of the cage wall for the front wall and side walls, respectively. By fixing the structure, even if a passenger leans against the lightweight car wall, the car wall will not bend and hit other equipment or make noise, which will prevent passengers from feeling uneasy. The purpose is to provide elevator cabs.

An embodiment of this invention will be described below with reference to FIGS. 4 and 5.

In FIGS. 4 and 5, the same reference numerals as in FIGS. 1 to 3 indicate the same or corresponding parts, and 17 and 18 indicate the back surfaces of the front wall 13 and the side walls 14, which are located approximately at the center in the height direction. This is a reinforcing member for preventing deflection that is passed horizontally in the lateral direction. In the front wall 13, both ends of wall plate materials 13a, 13b, and 13c having a square cross section are fixed to adjacent ones with fasteners 20 made of bolts and nuts, and pillars 21 at the four corners of the car room 5
The reinforcing member 17 is fixed to the wall plate materials 13a to 13c and the pillar 21 with fasteners 22 made of bolts and nuts. Similarly to the case of the front wall 13 described above, the side wall 14 is also provided with reinforcing members 1 on the wall board materials 14c and 14d that constitute these walls.
8 is fixed. In addition, since the gap A between the reinforcing member 18 of the side wall 14 and the vertical column 12 cannot be made very large, the reinforcing member 18 is attached to the mounting bracket 25 fixed to the vertical column 12 with a fastener 24 made of bolts and nuts. The combined vibration isolator 19 is engaged and interposed between the reinforcing member 18 and the vertical column 12.

In the car compartment of this embodiment configured as described above, even if a person such as a passenger intentionally leans against the side wall 14, or even if a lateral pushing load is applied, the vibration isolator 19 pushes the vertical column 12. Therefore, since the vertical column 12 has high rigidity, the side wall 14 is formed by the vertical reinforcing member 14.
a, not only the strength of the joint 14b, but also the strength of the reinforcing member 1
The vertical pillars 12 serve as reinforcement through the shafts 8 and back up the rigidity. Therefore, if the thickness B of the cage wall 9 is the same as that of the conventional one, the reinforcing member 1
7 and 18, but the section modulus Z of the car chamber wall 9 is made as large as possible within the allowable dimensions for the layout, and the reinforcing member 17, form 18. Therefore, in the conventional one, the front wall 13,
In the side wall 14, the wall plate materials composing these were bent one by one, but in this embodiment, for example, when a load is applied to the front wall 13, the wall plate materials 13a to 13c bend. Deflection is first regulated by the reinforcing member 17 being fixed to the pillar 21, and if the entire front wall 13 tries to flex in a membrane-like manner, it is regulated by the side wall 14 via the pillar 21. . Therefore, even if the rigidity of the wall plate material of the car room wall 9 is lower than that of the conventional one, the rigidity is increased, and the wall plate material can be made thinner, resulting in weight reduction from an energy saving perspective. , and reduce the amount of deflection of the car room wall 9, which eliminates the feeling of anxiety among passengers. Also, by not changing the wall thickness from the conventional one, the wall plate material can be molded using the same mold as the conventional one, and these can be manufactured at low cost. It becomes possible. Furthermore, during installation,
The reinforcing members 17 and 18 assembled in units of the front wall 13 and side wall 14 serve as gauges to flatten the wall surface, eliminating the need to adjust the entrance and exit of the wall surface, making installation easier and saving labor. It becomes possible to

In addition, in this invention, the reinforcing members 17, 18
It does not necessarily have to be located at the center of the front wall 13 or side wall 14 in the height direction, as long as it is placed at a location corresponding to the midpoint between the passenger's waist and shoulder, which bends the most when the passenger leans or pushes. good.

As explained above, in the elevator car according to this invention, a reinforcing member for preventing deflection of the car wall is passed through the back side of the car wall in the horizontal direction at an intermediate position in the height direction in units of the front wall and the side wall. In addition, the reinforcement member for preventing deflection is held on the vertical column of the framework via a vibration isolator,
The wall board materials for the front wall and side walls are each fixed to these reinforcing members, and these wall board materials are integrated and the front wall and side walls become membrane-like and deform, and are also supported by the vertical columns and flexed. By reducing the amount of weight, it is possible to lower the rigidity of the wall panel material, making it possible to reduce the thickness of these materials. ,
To prevent passengers from feeling uneasy or uncomfortable by ensuring that the front and side walls do not come into contact with equipment such as counterweights, or that the side walls do not come into contact with the vertical columns of the framework. Furthermore, the car wall can be manufactured at low cost using conventional equipment, and the front wall and side walls can be easily assembled, resulting in labor-saving installation.
