[Detailed description of the invention] Industrial field of application The present invention relates to a pop-up device in which a cathode ray tube (CRT) part of a television receiver can be retracted from the main body of the housing using a shaft made of metal or the like as a pivot. It is.

Such a conventional example is shown in FIG. A pop-up part 2 to which a CRT is attached is rotatably attached to a main body 1 of the casing via a support shaft 3, so that the pop-up part 2 can freely appear and retract from the main body 1. In this case, conventionally, a torsion coil spring 4 is used as a power source for driving the pop-up operation, but
Due to the variation in the weight of the CRT and the variation in the spring 4, the pop-up action may not go all the way up, or the pop-up action may be hit hard at the final point and hit the main body 1. It had a flaw of lack of character.

Structure of the invention In this invention, a pop-up part to which a CRT, etc. is attached is biased so that it can protrude from the main body of the casing, and is provided so as to be freely retractable, and a packing is attached to the piston, and the pop-up part is slidably inserted into the cylinder. An air damper that acts as a damper is installed between the pop-up part and the main body.
The urging force is increased to make the ejecting motion stable and reliable, and the air damper is used to soften the pop-up action.

DESCRIPTION OF EMBODIMENTS A television receiver using a pop-up device according to an embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same parts as in the prior art are designated by the same reference numerals as in FIG. 1, and the explanation thereof will be omitted.

In this device, one or two air dampers 5 are installed between the pop-up section 2 to which the CRT is attached and the main body 1.

A detailed example of this air damper 5 is shown in FIG. In this case, a piston 5b with a packing 5C attached thereto is inserted into a cylinder 5a to act as a damper.

The cylinder 5a is attached to the main body 1, but the mounting screw is slightly loose in the rotational direction.
It allows for some rotation. The packing 5c is arranged so that the piston 5b receives resistance only in the pulling direction.
It's stuck in. Also, the other piston 5b
is fixed to the pop-up part 2 of the CRT with a screw, and at this time also it is made to be able to rotate in the direction of rotation of the screw.

With this configuration, when the pop-up portion 2 of the CRT pops up and protrudes due to the driving force of the spring 4, the packing 5c acts to close the gap between the piston 5b and the bottom of the cylinder 5a. Only the amount of air that flows in through the gap between the screw 7 and the chrysanthemum washer 8 that are screwed to the bottom of the cylinder 5a enters the space 6 that is created, and the piston increases in proportion to the decrease in pressure in the space 6. The speed of 5b decreases. That is, the force in the opposite direction to the pop-up operation increases in proportion to the speed of the piston 5b. In this way, the damper effect is exhibited as the air damper 5,
The pop-up operation will be performed softly.

Further, when the pop-up portion 2 is stored, the packing 5c acts to open a gap with the cylinder 5a, so the air in the space 6 flows out without resistance through this gap, and no damper effect is exerted.

As a result, even if there is an air damper 5 in the spring 4, the pop-up part 2 can be moved stably and reliably by having a biasing force sufficient to completely complete the projecting operation of the pop-up part 2, including variations. It can be made into something.

Effects of the Invention As described above, according to the present invention, the pop-up operation of the pop-up portion can be freely made smooth and soft by the damping action of the air damper. Moreover, since the biasing force in the protrusion direction can be increased, the pop-up operation can be made stable and reliable.
