Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a packaging device for packaging a frame type cathode ray tube display monitor using a cushioning material.

BACKGROUND OF THE INVENTION As shown in FIGS. 1 to 3, the above-mentioned frame type cathode ray tube display monitor includes a cathode ray tube 1 to which a deflection coil is attached, a pair of side plates 2, 2 to which the cathode ray tube 1 is attached, and each side plate 2. , a pair of mounting brackets 3, 3 fixed to the lower ends of 2, respectively, and both brackets 3, 3 to connect the mounting brackets 3, 3.
It consists of a bottom plate 4 disposed between the bottom plate 4 and a printed circuit board 5 installed on the bottom plate 4 that forms the required circuit, and the tightening position of one screw 6 with respect to the mounting brackets 3 of the side plates 2, 2. By changing the angle of the cathode ray tube 1 (for example, 0 degrees, 5 degrees, etc.)
can now be changed. The illustrated example is
Although it is possible to switch between 0 degrees and α degrees in two stages, it is also possible to change to more stages.

When packaging such a cathode ray tube display monitor using cushioning materials, conventionally, for a display monitor with a 0 degree inclination as shown in FIG. (The illustrated example shows two upper and lower pieces, but the upper and lower left and right sides are the same.)
Hold the cardboard box 9 horizontally, and then
On the other hand, for a display monitor with a cathode ray tube tilted by α degrees as shown in Fig. 2, the bottom plate 4 is held horizontally as shown in Fig. 5. Cushioning materials 10 and 11, which are different from the cushioning materials 7 and 8 shown in FIG. 4, are used to sandwich them from above and below.

Problems to be solved by the invention However, with the above-mentioned conventional packaging means,
Suitable cushioning materials are prepared according to the different inclinations of cathode ray tubes. Therefore, when the inclination is divided into multiple stages, there are many types of cushioning materials, which is troublesome to manage, and it is also costly. The drawback was that it was expensive.

SUMMARY OF THE INVENTION The present invention eliminates the above-mentioned drawbacks of the conventional art, and aims to provide a packaging device in which a cushioning material can be used in common even though the inclinations of cathode ray tubes are different.

Means for Solving the Problems In order to achieve the above object, the present invention provides an upper cushioning material and a lower cushioning material that sandwich and hold a frame type cathode ray tube display monitor from above and below, and the upper and lower cushioning materials A recess into which the curved end of the cathode ray tube fits is provided in each of the tubes, and the upper and lower cushioning materials hold the cathode ray tube in a substantially vertical position, and the upper and lower cushioning materials collide with each other at the rear end. In addition, each of the collision portions has a stepped portion, and both stepped portions are engaged with each other such that the stepped portion of the upper cushioning material is located on the inside.

Effects With the above-described configuration, the present invention allows one kind of upper and lower cushioning materials to be used in common for multiple types of cathode ray tube display monitors in which the inclinations of the cathode ray tubes are different from each other. Since the colliding portions are provided with stepped portions that engage with each other, the cathode ray tube display monitor can be held more stably.

Embodiments Examples of the present invention will be described below with reference to FIGS. 6 to 10.

6 to 8 show a first embodiment of the present invention, in which a concave portion 22 in which a curved portion from the projection surface to the funnel surface at the tip of the cathode ray tube 1 fits into the lower cushioning materials 23, 23. On the other hand, the upper cushioning material 2
1 and 21 are similarly provided with a recess 24 into which the curved part of the cathode ray tube 1 fits, and the cathode ray tube 1 is inserted into the upper cushioning material 2.
1, 21, and the lower cushioning materials 23, 23 are used to hold it in a substantially vertical state by sandwiching it from above and below.

Figure 6 shows the case where the inclination of the cathode ray tube 1 is 0 degrees.
In this case, the bottom plate 4 and the mounting bracket 3 are in a horizontal state, making it possible to stably hold the cathode ray tube display monitor.

FIG. 7 shows a state in which the display monitor with the cathode ray tube 1 tilted by α degree is stored and held. In this case, since the cathode ray tube 1 is approximately perpendicular to the bottom surface, the mounting bracket 3 and the bottom plate 4 The rear end will be lifted up. However, in this case, cathode ray tube 1
The weight of the tube is much heavier than that of the bottom plate 4 and the mounting bracket 3, and since the heavy cathode ray tube 1 is held in position by being sandwiched between the upper and lower cushioning materials 21 and 23, the In FIG. 7, the holding state is also stable.

In this way, the recesses 22 and 24 into which the curved portion at the tip of the cathode ray tube 1 fits are arranged in the upper and lower cushioning materials 21 and 2.
3, it is possible to use the buffer material in common for display monitors with different inclinations of the cathode ray tubes 1, and to stably hold the display monitors.

By the way, before the cathode ray tube display monitor is held by the upper and lower cushioning materials 21 and 23 and stored in the cardboard box 9, if the cathode ray tube 1 is tilted as shown in FIG. There is a risk of rotation in the direction. Figures 6 and 7
In the example shown in FIG. 8, in order to prevent this possibility, stepped portions 25 and 26 are provided at the rear end where the upper cushioning material 21 and the lower cushioning material 23 collide, and these stepped portions 25 and 26 engage with each other. That's what I do. That is, by supporting the movement of the upper cushioning material 21 due to the force of clockwise rotation of the display monitor with the stepped portion 26 of the lower cushioning material 23, it becomes possible to more stably hold the cathode ray tube display monitor. .

FIGS. 9 and 10 show further embodiments of the present invention.

This embodiment is intended to reduce the amount of cushioning material used and achieve a low-cost structure, and the upper cushioning material 2
A portion of the cushioning material at the rear end colliding portion of the lower cushioning material 23' and the lower cushioning material 23' is removed to provide a gap between the two, and the gap is connected with corrugated paper 27. For this purpose, fitting grooves are provided in the opposing parts of the upper and lower cushioning materials 21' and 23', and both ends of the corrugated paper are inserted into these fitting grooves, and the upper and lower cushioning materials are , the lower cushioning materials 21', 23' are prevented from colliding with each other and their positions are restricted. This embodiment can provide the same effects as the embodiments shown in FIGS. 6 to 8.

Effects of the Invention As explained above, according to the present invention, the upper and lower cushioning materials are each provided with a recess into which the curved end of the cathode ray tube fits, and the cathode ray tube is held in a substantially vertical state. One type of upper and lower cushioning material can be used in common for a plurality of types of cathode ray tube display monitors having different inclinations, which is extremely advantageous in terms of cost and management. Further, by providing stepped portions at the rear end colliding portions of the upper and lower cushioning members so as to engage with each other, the cathode ray tube display monitor can be held more stably.
