2. Description of the Related Art FIG.
As shown in (1), a tray 1 and a tray guide 2 are provided.
The tray 1 includes a bottom plate 1a, a front plate 1b, left and right side plates 1
c, 1c, and a hole 1a ', 1b', 1c ', 1 formed in a box shape having a rear plate 1d for ventilation and weight reduction.
c ', 1d' and a handle 1e.
Is a bottom plate guide (bottom portion) 2 to which the sliding plate 2c is attached.
a and side plate guides (side portions) 2b, 2b. Then, the tray 1 is placed on the bottom plate guide 2a, and the side plate guides 2b, 2b are moved to the left and right side plates 1c, 1c of the tray 1.
And is guided in the drawer direction.

[0003]

In the above-mentioned conventional tray device such as a power supply device, the tray 1 falls off from the tray guide 2 when the tray is pulled out.

The present invention has been devised in view of the above points, and it is possible to assemble a tray on which a power supply device or the like is mounted by inserting the tray into a tray guide to be fixed and then pushing the tray. The drawer can be prevented when pulling out, and the tray can be pulled out to the maximum so that the tray does not fall down due to the action of the center of gravity. To provide.

[0005]

According to the present invention, as a means for solving the above-mentioned problems, a tray 1 on which a power device or the like P can be placed and which has at least one side plate 1c, And a tray guide 2 having two side plate guides 2b, 2b, the length h2 of which is shorter than the length h1 of the side plate 1c. A projection 3 for preventing escape is provided on the outer surface side, and corresponding to the projection 3, an inclined edge 4a and an inclined edge 4a rising from the near side in the drawing direction toward the depth direction at the upper end of the side plate guide 2b. And a stepped edge 4b which is steeply lowered from the upper end of the main body, a substantially triangular locking projection 4 for preventing escape is formed to extend therefrom. The center of gravity G when 1 is pulled out is the tray The protrusion 3 for preventing escape comes into contact with the step edge 4b of the locking protrusion 4 for preventing escape when it comes to the end of the guide 2 on the drawer side. A tray device such as a power supply device is provided.

[0006]

When the tray 1 is inserted into the tray guide 2 and then pushed in, the projections 3, 3 get over the locking projections 4, 4, whereby the tray 1 is assembled to the tray guide 2. The power supply device P is mounted on the tray 1 after the tray 1 is fitted into the tray guide 2 and
Either of the cases where the tray 1 is placed and stored in the tray 1 before being fitted into the tray guide 2 may be used. When trying to pull out the tray 1, the protrusion 3 stops coming into contact with the locking protrusion 4, so that the tray 1 does not fall out, so that the drawer is maximized and the tray 1 does not tilt forward and fall down. In order to pull out the tray 1, the tray 3 may be tilted to the front side, and the protrusion 3 may be positioned higher than the locking protrusion 4 and pulled out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a tray device such as a power supply device of the present invention will be described below with reference to FIGS. 1 (a) and 1 (b). The tray device such as a power supply device of this embodiment includes a tray 1 and a tray guide 2 which are formed from a thin steel plate by sheet metal working and then painted or plated. The tray 1 includes a bottom plate 1a on which a power device or the like P can be placed, a front plate 1b formed by bending the bottom plate 1a in four directions, left and right side plates 1c, 1
c, and a rear plate 1d. Holes 1a ', 1b', 1c ', 1c', 1d 'for ventilation and weight reduction are formed in each surface forming the tray 1. A channel-shaped handle 1 is provided on the front plate 1b.
e is fixed. The tray guide 2 includes a bottom plate guide (bottom portion) 2a, left and right side plate guides (side portions) 2b,
2b. A sliding plate 2c made of plastic such as polyester is adhered to the upper surface of the bottom plate guide 2a. The length h2 of the left and right side plate guides 2b, 2b is, for example, the length h1 × of the side plate 1b.
(1/2 to 1/4). Tray guide 2
The tray 1 is placed on the bottom plate guide 2a, and the side plate guides 2b, 2b overlap the outside of the left and right side plates 1c, 1c of the tray 1 to guide in the pull-out direction.

In particular, in the storage and draw-out device for a power supply device or the like according to the present invention, bar-shaped projections 3, 3 for preventing escape are provided between the holes 1c ', 1c' on the outer surface on both sides of the side plate 1b of the tray 1.
Are provided, and locking projections 4 for preventing escape are protruded and extended correspondingly to the respective projections 3 at the middle positions of the upper ends of the side plate guides 1b. The locking projection 4 protrudes in a triangular shape from a sloped edge 4a that rises from the near side to the back in the drawing direction and a step edge 4b for preventing escape, which is a vertical edge, at a position halfway at the upper end of the side plate guide 1b. Has been extended.

Therefore, when the power supply device P or the like is placed on the tray 1 detached from the tray guide 2 to be installed and fixed, and the tray 1 is fitted into the tray guide 2 and then pushed in, the projections 3 are formed. The tray 1 is assembled to the tray guide 2 by going over the locking projections 4 and 4. When pulling out the tray 1 on which the power supply equipment P is placed,
The projection 3 stops contacting the step edge 4b of the locking projection 4 (FIG. 1).
(b)) At that time, the center of gravity G of the tray 1 on which the power supply device P is placed and stored comes near the end on the drawer side of the tray guide 2, but since the center of gravity G is not separated from the tray guide 2,
There is no danger that the tray 1 in which the power supply device P is placed and stored is inclined forward and falls. In order to pull out the tray 1, the protrusion 3 is stopped in contact with the step edge 4 b of the locking protrusion 4 before the tray 1 is pulled out.
Is tilted to the front side so that the projection 3 is positioned higher than the locking projection 4, and then the tray 1 is slightly pulled out and then pulled out.

The tray device such as a power supply device of the present invention includes a case where the tray 1 does not have the front plate 1b, the rear plate 1d, and the left or right side plate 1c and is not a box-shaped tray. Tray 1 has holes 1a 'for ventilation and weight reduction
This includes the case where the tray is not provided with １1d ′. This includes the case where the tray 1 is not provided with the channel-shaped handle 1e. The case where the tray guide 2 is a tray guide without the sliding plate 2c is also included.

[0011]

As described above, according to the tray device such as the power supply device of the present invention, by adding a very simple pull-out prevention structure, the manufacturing cost can be slightly higher than that of the conventional device. Can be reduced to
Inserting the tray on which the power supply equipment etc. are placed into the fixed and fixed tray guide, and then pushing it in, can be assembled, and the tray does not fall out.
In addition, the tray can be pulled out as much as possible so that the tray does not tilt forward due to the center of gravity, and when it is necessary to pull out the tray, pull out the tray to the maximum and tilt the tray forward to lock the protrusion Since the tray can be detached from the projection and the center of gravity of the tray can be used at that time, the function of lowering the pushing force to tilt the tray forward is very small.
