DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car capable of performing work on the upper part of the car without being obstructed by wiring.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view of a conventional general elevator car.

[0003] As shown in FIG. 4, the holding table 9 is formed of a long body having an L-shaped cross section, and is supported on a pair of vertical frames 8 provided on both sides of the car 1. A non-operating door machine is mounted on the holding table 9. A plurality of electric appliances such as an operation panel 2, a ventilation fan 3, and a lighting fixture 4 are provided on a side plate and an upper portion of the car 1.
These electric appliances are connected to a connection box 7 by wiring composed of a power line 5 and a signal line 6, respectively. This junction box 7
Are connected to a power supply device and a control panel in a machine room (not shown), and power and signals are transmitted and received between the connection box 7 and the power supply devices and the control panel in the machine room. In addition, as shown in FIG. 4, above the car 1, the linear portions of the power line 5 and the signal line 6 are accommodated inside the holding base 9 so as to extend along the longitudinal direction of the holding base 9. Elongation,
It is fixed to the holding table 9 by a bind wire 10.

[0004] Since there are a plurality of power lines 5 and signal lines 6 described above and they are usually set longer than necessary,
When the linear portions of the power line 5 and the signal line 6 are fixed along the holding base 9 as described above, the power line 5 and the signal line 6 cannot be accommodated in the holding base 9 and the power line The portion where 5 is left is a surplus portion 5a, and the portion where the signal line 6 is left is a surplus portion 6a, which tends to be left on the car 1 as shown in FIG.

As described above, if the extra length portions 5a and 6a are left unattended, when an operator works on the upper part of the car 1,
A situation in which the foot is taken off or the foot is hooked and the wire is disconnected easily occurs, and when such a situation occurs, the work efficiency is reduced. In addition, the extra length part 5a left at the upper part of the car 1
6a is not preferable in terms of aesthetics.

As a related application of this kind, Japanese Utility Model Laid-Open No.
There are those described in JP-A-2-70878. In this prior art, a wiring duct is provided above the car 1, and the power line 5 and the signal line 6 are accommodated in the wiring duct. Thereby, the extra length portions 5a and 6a as shown in FIG. 4 are prevented from being generated.

[0007]

As shown in FIG. 4 described above, if the extra length portions 5a and 6a of the wiring are left undisturbed, the work on the upper part of the car 1 is likely to be hindered. In addition, as in the related application, when the wiring duct is provided, the extra length portions 5a and 6a can be prevented from being exposed to the upper portion of the car 1, but a new wiring duct and parts related to the mounting are required. Become. For this reason, another problem that the number of parts increases, material costs, transportation costs, work costs, and the like increase, and the manufacturing cost of the entire elevator increases.

[0008] An object of the present invention is to provide an elevator car in which the work on the upper part of the car 1 can be performed without any trouble and the increase in the number of parts can be suppressed.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a door machine is mounted on a pair of vertical frames provided on both sides of a car. In the elevator car, which has a holding table, a plurality of electric appliances provided in the car, a connection box provided on the top of the car, and wiring connecting the plurality of electric appliances and the connection box, Place the table on its opening
Sectional shape having a hook-like portion is more formed on the elongate body of the C-shaped in a square and below, are to the wiring configuration is accommodated by bending in the interior of the holder.

According to the first aspect of the present invention, when the wiring is appropriately bent and housed in the holding table, the holding table is hooked above and below the opening.
Because it has a click-shaped portion, the wiring is housed in the interior of the holder
It engaged with the hook-like part below the upper, without jumping cage upwardly ride from the front opening of the holder, thus, Do is possible to present the extra length portion of the wire to the passenger cage top <br/> In this way, the work on the upper part of the car can be performed without any trouble. Further, since only the shape of the holding table is changed, an increase in the number of parts can be suppressed.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of an elevator car of the present invention, FIG. 2 is a plan view of the embodiment shown in FIG. 1, and FIG. 3 is an embodiment of the embodiment shown in FIG. It is a front view. Note that the same reference numerals in FIGS. 1 to 3 denote the same components as those shown in FIG. 4 described above.

That is, even in the present embodiment, a plurality of electric appliances such as an operation panel 2, a ventilation fan 3, and a lighting fixture 4 are provided on the side plate and the upper part of the car 1, and these electric appliances are provided. Are connected to the connection box 7 by wiring composed of a power line 5 and a signal line 6, respectively. The connection box 7 is connected to a power supply unit and a control panel in a machine room (not shown), and power and signals are transmitted and received between the connection box 7 and the power supply units and the control panel in the machine room. These configurations are the same as those shown in FIG.

In this embodiment, in particular, it is supported on a pair of vertical frames 8 provided on both sides of the car 1,
The holding table 11 on which a door machine (not shown) is placed is formed in a long body having a C-shaped cross section. Further, the plurality of power lines 5 and the signal lines 6 are connected to the bent portions 5c, 6c.
Are stored in the holding table 11 in a state where they are formed.

In the embodiment configured as described above, as described above, the bent portions 5c and 6c are formed on a part of the power line 5 and the signal line 6.
c, the bent portions 5c and 6c are housed inside the holding base 11, and the cross section of the holding base 11 has a C-shape. Upper and lower hook-shaped portions 11b, 11c forming a C-shape
And does not protrude from the opening 11a on the front surface of the holding base 11 in the upper direction of the car, that is, in the direction of the arrow 15a in FIG. 1 or in the direction of the arrows 15b and 15c in FIGS. There is no extra length of wiring on the top.

According to the embodiment configured as described above, the extra lengths of the power line 5 and the signal line 6 are not exposed at the upper part of the car 1, so that these telephone lines 5 are not exposed.
Also, the signal line 6 does not hinder the work, and the work efficiency can be improved. In addition, since the shape of the holding table 11 is merely changed, the number of parts does not increase, so that an increase in manufacturing cost can be suppressed.

[0017]

[Effect of the Invention] As described above, in the invention according to claim 1 of the present invention, the holding body, above and below the opening portion
The cross-sectional shape with a hook-shaped part is a C-shaped long body
More form, since it was accommodated by bending the wire in the interior of the holding member, riding without exposed wiring the car top, therefore, without causing hinder the work in the passenger cage top,
The efficiency of the corresponding work can be improved, and excellent aesthetics can be secured. Further, an increase in the number of parts can be suppressed, so that an increase in production cost can be suppressed.
