Description

[Detailed Description of the Invention] The present invention relates to a device for hooding the cathode ray tube screen of a television receiver, and more particularly to a composite television receiver in which a television receiver, a radio receiver, and a tape recorder are configured as one device. The present invention relates to a hood device suitable for a machine.

FIG. 1 is an external perspective view of a composite television receiver in which the present invention has been implemented, and 1 shows a structure in which the mechanical section 2 of the tape recorder, the television receiver, the radio receiver, the internal circuits and speakers of the tape recorder are incorporated. As shown in the main part sectional view of FIG. 2, the device main body 1 is provided with a recess 3, and the front inner wall portion 10 of the recess 3 is provided with a tapered portion 11, A box body 5 in which a cathode ray tube 4 is housed is housed in the recess 3. Further, the rear part of the box body 5 is pivotally connected to the device main body 1 by a pivot joint part 6 inside the recess 3,
The front part is open, and the screen of a cathode ray tube 4 is arranged at the open end 7. Further, one end of the open end 7 of the box body 5 is rotatably attached to the box body 5 through a pivot point 8, and a first end is provided on both sides of the pivot point 8 and can abut the tapered portion 11. Contact part 9
A hood 9 having a second abutting portion 9b and a second abutting portion 9b is provided.

FIG. 3 shows a means for rotating the box 5 around the pivot 6 to expose the screen of the cathode ray tube to the outside of the device main body 1. A fan-shaped gear 12 centered on the attachment portion 6 is fixed, and an engagement hole 13 is provided. 14 is a coil spring whose one end is connected to the box 5 and the other end is connected to the inner surface of the recess 3 of the device main body 1 for biasing the box 5 upwardly of the device main body.

Further, the equipment main body 1 is provided with a hydraulic damper 15, and a gear 16 of this hydraulic damper 15 and the sector gear 12 mesh with each other, and the hydraulic damper 15 resists the biasing force of the coil spring 14. This acts to cause the box body 5 to rotate slowly. As shown in FIG. 4, the box body 5 is spaced a predetermined distance from the bottom surface 3a of the recess 3 in the stored state, and is in a locked state with the engagement piece 17 engaged in the engagement hole 13. There is. The engaging piece 17 is rotatably mounted on a shaft 18 and is urged by a spring 19 so as to always protrude outward from the inner surface of the recess 3.
Figure 5 shows the sector gear 12 and the gear 1 of the hydraulic damper 15.
6 is a sectional view of a main part showing the connection state of the coil spring 14.

Now, when the top plate of the box 5 is pressed downward from the state where the box 5 is housed in the recess 3 of the device main body 1, the engagement piece 17 will come off from the engagement hole 13, the locked state will be released, and the pressing will stop. The box body 5 is exposed to the outside from the recess 3 around the pivot joint 6 by the urging force of the coil spring 14 as shown in FIG. 7. At this time, the hood 9 attached to the box body 5 Do something like this.

That is, when the box body 5 is stored in the recess 3, the first contact portion 9a of the hood 9 and the tapered portion 11 provided on the front inner wall portion 10 of the recess 3 come into contact with each other. The hood 9 is housed inside the box body 5 as shown in FIG. As shown in FIG. 8, the second contact portion 9b of the hood 9 slides into contact with the tapered portion 11 as the box body 5 rotates, and the second contact portion 9b of the hood 9 slides into contact with the tapered portion 11.
Since the hood 9 is pushed into the inside of the box 5, the hood 9 rotates about the pivot point 8 of the box 5 as a fulcrum and projects from the open end 7 of the box 5. FIG. 9 is an external perspective view showing a state in which a hood 9 is applied to a cathode ray tube screen of a composite television receiver.

As described above, with the hood device of this invention, the hood is automatically applied when the CRT screen is exposed outside the device body, and the hood is automatically stored when the CRT screen is stored inside the device body, so the hood can be extended and stored without touching it directly, which is convenient. Also, since the hood is stored inside the box, it does not take up extra space inside the device body, and it also has an excellent design.

Claims (1)

[Scope of utility model registration request] A tapered part is provided on the front inner wall of a recess provided in the main body of the device, and the other end side of a box with an open end that is housed in the recess is pivoted inside the recess, and the cathode ray tube screen is arranged. A hood is provided at an open end of the box body, one end of which is rotatably pivoted to the box body, and has first and second abutting parts on both sides of the pivoting point that can abut the tapered part, When the box body is housed in the recess, the hood is housed inside the box body due to the abutment between the first contact portion and the tapered portion, and the box body engages the pivot joint portion. When the hood is exposed from inside the recess at the center, the second contact portion slides into contact with the tapered portion so that the hood protrudes from the box body.
