2. Description of the Related Art As a conventional movable solar radiation device, there are the following two types.
Two things have been proposed. First, as the first device,
Japanese Unexamined Patent Application Publication No. 4-54431 includes a vertical moving rail supported by a gantry and provided above, and a semicircular horizontal moving rail installed on the floor surface. The vertical moving rail is provided on the horizontal moving rail. It is disclosed that the gantry is configured to be horizontally movable, and the light irradiation bank is vertically moved along the vertical movement rail. Further, as a second device, in Japanese Patent Application Laid-Open No. 7-280706, a light irradiation bank is vertically moved on a linear bank rail that rotates and moves on a large circular rail with a center point of the circular rail as a rotation center. There is disclosed a solar radiation device which is rotatably suspended.

[0003]

In order to radiate light from the front, rear, left, right, diagonal direction and upward direction of the passenger car in the above-mentioned first conventional apparatus, it is necessary to extend the arch rail from the upper part of the passenger car to the floor surface. there were. By extending the arch rail from the upper part of the passenger car to the floor surface, the turning radius of the arch rail must be large because the distance from the turning center to the floor surface of the arch rail is inevitable. Need.

Further, since the light irradiation device has an enormous amount of wiring of the light bulb, the turntable has a semi-circular shape or a part thereof in order to secure a wiring space as in the first conventional device. It is necessary to make a notch, or to secure a wiring space outside the turntable like the above-mentioned second conventional device. For that reason, it is necessary to make the device large even if it can rotate 360 degrees. , Requires a large room to install.

Therefore, an object of the present invention is to easily move the light irradiation main bank to any position above, below, to the left, to the right and above the irradiated object such as a passenger car in a small test room, and to move the irradiated object. Another object of the present invention is to provide a movable light irradiating device that can irradiate light from an arbitrary position and can be installed in a small space.

[0006]

The first feature of the present invention for achieving the above object is to provide a turntable provided on an upper portion on which an object to be irradiated is installed, an arch rail suspended from the turntable, and A bank frame movable along the arch rail, a light irradiation main bank composed of a large number of light bulbs suspended on the bank frame and their reflecting mirrors, and an auxiliary bank provided alongside the light irradiation main bank. Equipped with means for easily moving the light irradiation main bank to any position above, below, to the left, to the right of the passenger car, etc. without extending the arch rail to the floor by eccentrically hanging the bank frame downward. It is in.

According to the present invention, since the arch rail is not extended to the floor, the turning diameter of the arch rail is from the turning center to the hollow tip of the arch rail, compared to the case where the arch rail is extended to the floor surface. And, because the turning diameter can be made smaller, the installation space can be made much smaller.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The device of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a diagram showing the overall configuration of the present invention.

In FIG. 1, a building structure 1 is provided with an interior material 2. A test chamber 4 is defined by the interior material 2 and the floor 3. The passenger car 5 is put in and taken out of the test room 4 through the opening 6 of the interior material 2. The opening 6 is provided with a door 7. A bell mouth 8 is provided in front of the door 7 and in front of the passenger car 5 for blowing out wind, snow, or blister for testing the passenger car 5. A turntable 9 is provided on the upper interior material 2, that is, on the ceiling of the test chamber 4. An arcuate arch rail 10 is suspended below the turntable 9, and the arch rail 10 can be rotated 360 degrees by rotating the turntable. That is, at the top of the arch rail 10,
Since the motor 13 is provided and its shaft is connected to the slewing wheel 12, the turntable 9 is rotated by the drive of the motor 13 via the slewing wheel 12, and the arch rail 10 is rotated as indicated by an arrow A.

A bank frame 11 is suspended from the arch rail 10 by a suspension member having a moving mechanism. The bank frame 11 is provided with a light irradiation main bank 14 to which a heat radiation bulb 15 and a reflecting mirror 16 thereof are attached. As will be described later, the bank frame 11 is configured to move on the arch rail 10. The bank frame 11 and the light irradiation main bank 14 are displaced (eccentric) from the center point of support.
It is suspended on the arch rail 10. This is to make it possible to irradiate the center of the sky when it is located at one end of the arch rail, and the horizontal line (horizon) when it is located at the other end, and to minimize the radius of rotation of the arch rail. Is.

Further, in this embodiment, the arch rail 10 is formed in a semi-circular shape so as to be biased toward one end side as shown in the figure.
Supports (with eccentricity). The reason is that when the light irradiation main bank 14 is located in the sky center state, the arch rail position where the light irradiation main bank 14 is substantially parallel to the floor surface is one end side, and the other side is the light irradiation main bank 14 is horizontal.
(Horizontal line) The position is set to be close to the state.
This makes it possible to simulate solar radiation in all directions by rotating the support position on the ceiling side. Further, the heat radiation bulb 15 provided in the light irradiation main bank 14 is
Although shown only for the rows, they are arranged in multiple planes on a square plane. In addition, this heat-dissipating light bulb is arranged so that the corners of the bank are reduced in order to make the turning radius as small as possible (the turning radius is affected by the diagonal dimension of the bank).

Further, in this apparatus, an auxiliary bank 22 is provided. This auxiliary bank moves on a straight rail mounted at a position higher than the arch rail so that it can move to the ceiling of the test chamber 4 without hitting the arch rail 10 mounted on the turntable 9. The moving means of the auxiliary bank drives the motor 21 provided on the traveling body side to rotate the roller, so that the auxiliary bank 22 is irradiated with light.
It can be close to or separated from the four sides.
The auxiliary bank also has a plurality of heat radiation bulbs arranged in a plane.
The auxiliary bank is also eccentrically attached to the arch rail 10 side with respect to the center of the support portion of the straight rail.

By providing the auxiliary bank 22 in this manner, the auxiliary bank 22 is arranged in the light irradiation main bank 14 so that the light amount and the light intensity of the light irradiation main bank 14 are not insufficient. And, it is possible to obtain the light intensity (when the sun is located in the center of the sky, the solar radiation state is the maximum, but this state can be simulated). Further, by providing the auxiliary bank 22, it is not necessary to increase the size of the light irradiation main bank 14 provided on the arch rail side,
Not only can the turning radius be reduced, but the power consumption required to drive the device itself can be reduced.

FIG. 2 is a diagram showing a wiring system of the movable light irradiation device. In FIG. 2, the light irradiation main bank 14 is

The cable bearers 30 and 31 may be a system such as a curtain rail. The plurality of heat radiation bulbs 15 provided in each bank can be selected by a switch of a control panel (not shown) to perform blinking control. By controlling the heat radiation bulb 15 to blink, the amount of light and the light intensity to the irradiation target can be controlled.

A twist-resistant cable is used as the cable so that the turntable 9 or the like does not twist the cable to cause a disconnection or the like.

FIG. 3 is a diagram for explaining the tilt drive of the light irradiation main bank. In FIG. 3, the bank frame 11 includes a motor 17 on the rear side of the light irradiation main bank 14,
