[Industrial applications]

 The present invention is designed to pull out a tray, place various power supply devices in an array, push the tray in and close it, and when the need arises, pull out the tray to replace and check various power supply devices. The present invention relates to a tray device, such as a power supply device, which is extremely inexpensive so that the tray does not pull out or overturn.

[0002]

[Prior art]

 A conventional tray device such as a power supply device includes a tray 1 and a tray guide 2 as shown in FIG. The tray 1 is formed in a box shape having a bottom plate 1a, a front plate 1b, left and right side plates 1c, 1c, and a rear plate 1d, and vent holes 1a ', 1b', 1c ', 1c for ventilation and weight reduction. The tray guide 2 is composed of a bottom plate guide (bottom part) 2a and a side plate guide (side part) 2b, 2b to which a slide plate 2c is attached. Then, the tray 1 is placed on the bottom plate guide 2a, and the side plate guides 2b and 2b are overlapped with the outsides of the left and right side plates 1c and 1c of the tray 1 and guided in the pull-out direction.

[0003]

[Problems to be solved by the device]

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

The present invention has been devised in view of the above-mentioned points, and the tray on which the power supply device or the like is placed can be assembled by fitting the tray guide into the tray guide fixed and then pushing the tray guide. When pulling out the tray, pulling out of the tray is maximized to prevent the tray from falling due to the center of gravity, and the manufacturing cost for the pullout prevention structure is kept low. To provide a device.

[0005]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a tray 1 on which a power source device P can be placed and which has at least one side plate 1c, and a tray h on which the tray 1 can be placed and which has a height h2. In a tray device such as a power supply device, which is composed of a tray guide 2 having two side plate guides 2b 1 and 2b extending vertically up to a length shorter than a height h1 of 1c, a protrusion for preventing escape is provided on the outer surface side of the side plate 1c. 3 is attached to the side plate guide 2b at the upper end of the side plate guide 2b, the slanted edge 4a rising from the front in the drawing direction to the depth direction, and the step falling sharply from the upper end of the slanted edge 4a. A substantially triangular locking protrusion 4 for preventing the escape defined by the end edge 4b is extendedly formed, and the center of gravity G when the tray 1 is pulled out by placing and storing the power supply device P on the tray 1 Is the end of the tray guide 2 on the drawer side The tray device such as a power supply device is characterized in that the protrusion 3 for preventing escape comes into contact with and stops at the step edge 4b of the locking protrusion 4 for preventing escape. To do.

[0006]

[Action]

 When the tray 1 is fitted into the tray guide 2 and then pushed in, the projections 3 and 3 pass over the locking projections 4 and 4, so that the tray 1 is assembled to the tray guide 2. The power source device P is mounted and stored in the tray 1 after the tray 1 is fitted into the tray guide 2 and when the tray 1 is mounted and stored in the tray 1 before being fitted in the tray guide 2. Either case is fine. When the tray 1 is pulled out, the protrusion 3 stops contacting with the locking protrusion 4 so that the tray 1 does not drop out, and there is no risk that the tray 1 will be maximized and the tray 1 will tilt forward and fall. In order to pull out the tray 1, it is sufficient to tilt the tray 1 forward so that the protrusion 3 is positioned higher than the locking protrusion 4 and then pulled out.

【Example】

 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 the power supply device of this embodiment is composed of a tray 1 and a tray guide 2 which are formed from a thin steel plate by sheet metal working and then coated or plated. The tray 1 is formed in a box shape including a bottom plate 1a on which a power supply device P can be placed, a front plate 1b bent in four directions of the bottom plate 1a, left and right side plates 1c and 1c, and a rear plate 1d. Has been done. Vents 1a ', 1b', 1c ', 1c', 1d 'are formed on each surface forming the tray 1 for ventilation and weight reduction. A channel-shaped handle 1e is fixed to the front surface of the front plate 1b. The tray guide 2 is formed in a channel shape including a bottom plate guide (bottom part) 2a and left and right side plate guides (side parts) 2b, 2b. A sliding plate 2c made of plastic such as polyester is attached to the upper surface of the bottom plate guide 2a. The left and right side surface plate guides 2b and 2b are provided with a short length h2, for example, the length h1 × (1/2 to 1/4) of the side surface plate 1b. In the tray guide 2, the tray 1 is placed on the bottom plate guide 2a, and the side plate guides 2b, 2b are overlapped with the outside of the left and right side plates 1c, 1c of the tray 1 and guided in the pulling direction.

Particularly, in the storage and withdrawal device of the power supply device of the present invention, rod-like projections 3 and 3 for preventing escape are provided between the outside holes 1c 'and 1c' on both sides of the side plate 1b of the tray 1. Corresponding to each protrusion 3, locking protrusions 4 and 4 for preventing escape are provided at positions midway along the upper ends of the side surface plate guides 1b and 1b. The locking projection 4 projects in a triangular shape from a sloped edge 4a that rises from the front to the back in the drawing direction to the middle of the upper end of the side plate guide 1b and a step edge 4b for preventing escape that is a vertical edge. It has been postponed.

Therefore, when the power source device P etc. is placed on the tray 1 removed from the tray guide 2 which is 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 overcoming the locking projections 4 and 4. When the tray 1 on which the power source device P is placed and housed is pulled out to the maximum, the protrusion 3 stops contacting with the step edge 4b of the locking protrusion 4 (FIG. 1 (b)), and at that time, the power source device etc. The center of gravity G of the tray 1 on which P is placed and stored comes near the end of the tray guide 2 on the pull-out side, but since the center of gravity G is not displaced from the tray guide 2, the tray 1 on which the power supply device P and the like are placed and stored There is no risk of tipping forward and falling. In order to pull out the tray 1, after the projection 3 stops contacting the step end edge 4b of the locking projection 4, the tray 1 is tilted forward and the projection 3 is positioned higher than the locking projection 4, and then a little. Draw out the tray 1 horizontally and pull it out.

The tray device such as the power supply device of the present invention includes a case where the tray 1 is not a box-shaped tray without the front plate 1b, the rear plate 1d, and either the left or right side plate 1c. It also includes the case where the tray 1 is a tray that does not have the vent holes 1a 'to 1d' for ventilation and weight reduction. This also includes the case where the tray 1 is a tray that does not have the channel-shaped handle 1e. This also includes the case where the tray guide 2 is a tray guide that does not include the sliding plate 2c.

[0011]

[Effect of device]

 As described above, according to the tray device of the present invention, such as the power supply device, by adding a very simple pull-out prevention structure, the manufacturing cost can be suppressed to be slightly higher than the conventional one. In addition, the tray on which the power supply device is placed can be assembled by inserting it into the tray guide that is fixed and installed and then pushing it in. The tray can be pulled out to the maximum so that it does not tilt forward, and when the tray needs to be pulled out further, pull out the tray to the maximum and then tilt the tray forward to release the protrusion from the locking protrusion. Since the center of gravity of the tray can be used at this time, the pushing force is extremely small and small to tilt the tray forward and downward. Having both the function of it.
