Description

[Detailed Description of the Invention] The present invention relates to a hood attachment device particularly for a television receiver, in which the hood body is rotatably and detachably attached to the equipment body, and the hood body is attached to the equipment body. The cathode conduit tube can be easily carried out, and the cathode conduit tube can be protected by storing it inside the device body when not in use.

Figure 1A-9 shows the basic structure of the present invention.

That is, in the present invention, a hood main body 1 having a substantially U-shape is provided, and an opening 3 is provided in the device main body 2 so that the substantially fan-shaped side plates 1a and lb of the hood main body 1 can be inserted into the device main body 2. is provided, and the hood body 1 is connected to the device body 2.
It is rotatably supported by a shaft 4 provided inside.

Figure 1A shows the state of the hood body 1 when it is in use, and Figure 1A shows the state of the hood body 1 when it is not in use.In both cases, the hood body 1 must be locked in that position. Must be.

Although not shown in FIG. 1, a cathode ray tube is installed inside the device main body 2, and correspondingly, an opening 5 is provided in the front surface of the device main body 2 as shown.

When the hood body 1 is stored, its top plate 1
C covers a part of the opening 5 to protect the cathode ray tube.

One embodiment will be described below with reference to FIGS. 2 to 4.

As shown in FIG. 4, the hood main body 1 has substantially fan-shaped side plates 1a and lb (only one side plate 1a is shown in the drawing).

) is provided with a shaft-fitting groove 6 in a so-called key part adjacent to the joint with the top plate part 1C, and an auxiliary groove 7 is provided adjacent to this shaft-fitting groove 6 so as to be approximately parallel to the shaft-fitting groove 6. This provides elasticity to the interior between the grooves 6 and 7.

- On the other hand, both side plates 1a and lb are provided with a positioning groove 8 at one end close to the joint with the top plate 1C, and a protrusion 9 at the other free end farthest from the top plate 1C. are integrated.

In addition, a shaft 10 is integrally provided on the main body 2 of the device in the vicinity of the opening 3, and the tip thereof is bent into a substantially dogleg shape, and this dogleg-shaped fitting portion 11 forms an integral part of the opening. An elastic positioning piece 12 is fixed inside so as to be located close to 3.

In the above configuration, when attaching the hood body 1 to the device body 2, the protrusion 9 of the hood body 1 is first inserted into the device body 2 through the opening 3, and then the shaft 10 is press-fitted into the shaft fitting groove 6.

As a result, the hood main body 1 is rotatably supported around the fitting portion between the shaft 10 and the shaft fitting groove 6 as a fulcrum, and the hood main body 1
When rotated in the clockwise (arrow A) direction, the protrusion 9 climbs over the substantially doglegged fitting portion 11 and is held between the device main body 2 and the substantially doglegged fitting portion 11. To position.

This state is shown in FIG. 2, and as a result, the hood main body 1 is maintained in the unfolded state shown.

On the other hand, when storing the hood body 1, the hood body 1 is rotated counterclockwise (arrow B).

As a result, the substantially fan-shaped side plates 1a and lb are housed in the device main body 2 through the opening 3, and eventually both side plates 1a.

The substantially doglegged fitting portion 11 of the positioning piece 12 fits into the positioning groove 8 of 1b, and the hood main body 1 is locked in this state.

This stored state is shown in FIG. In this case, only the top plate portion 1C of the hood body 1 is exposed outside the device body 2 so as to partially cover the opening 5.

Here, the fitting force between the shaft 10 and the shaft fitting groove 6 is made larger than the force by which the protrusion 9 overcomes the substantially doglegged fitting part 11 of the positioning piece 12, so that when the hood main body 1 is rotated, Make sure that the hood body 1 does not come off.

On the other hand, with the hood main body 1 opened as shown in FIG.
The hood main body 1 can be removed from the device main body 2 by pulling with a force stronger than the fitting force between the hood body 1 and the groove 6.

In the above embodiment, the free ends of the side plates 1a, lb are provided with protrusions 9 for positioning, but the protrusions 9 may be formed in the shape of a groove similar to the positioning groove 8.

However, in this case, the hood body 1 penetrates deeper into the device body 2, which is not practical.

As explained above, according to the present invention, the hood body can be rotatably and detachably attached to the device body, and since the auxiliary groove is provided adjacent to the shaft fitting groove, the hood When attaching the main body, it is only necessary to press the shaft into the shaft-fitting groove, and conversely, when removing the hood main body, it is only necessary to pull it, making it easy to attach and detach.

Further, since the hood main body is positioned by the elastic positioning piece both when unfolded and when stored, the unfolded state and the stored state are reliably maintained.

In particular, since the protrusion of the hood body is positioned between the fitting portion of the positioning piece and the device body to hold the hood body in an open state, the hood body can be opened wide.

Further, when the hood main body is stored, the top plate portion covers the display surface of the display device such as a cathode ray tube, so that the display device can be protected.
