Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a hood sliding mechanism in a television receiver configured such that a cathode ray tube can be moved in and out of a cabinet.

The present invention will be described below with reference to the accompanying drawings showing one embodiment thereof.

As mentioned above, this television receiver has a cathode ray tube that can be moved in and out of the cabinet, and the box that houses the cathode ray tube has a hood that acts as a light shield when the television receiver is used outdoors. is slidably attached, and when the CRT is stored in the cabinet, the display section can be opened by sliding the hood forward.
The hood can cover the operating section including the operating knobs and the like, and when the cathode ray tube is protruded from the cabinet, the hood can function as the original hood as described above.

In Figures 1 to 5, 1 is a cabinet, 2 is an opening provided on the top of the cabinet 1, and a cathode ray tube 3
The movable box 4 containing the
I try to store it inside.

The movable box 4 is rotatably supported on a shaft 5,
It is always urged by the elastic body 6 to protrude outward from the cabinet 1.

Reference numeral 7 denotes an operation section having a channel display section, various operation knobs, etc., and is formed one step lower than the top surface of the cabinet 1.

A locking mechanism 8 prevents the movable box 4 from rotating in the ejecting direction.

Reference numeral 9 designates a lock release button, and by pressing this button 9 as shown in FIG. The screen of the cathode ray tube 3 appears outside the cabinet 1 as shown in FIG.

This allows you to watch television broadcasts.

Further, 10 is a hood, which has a substantially U-shape as shown in FIG. 6, and has guide grooves 11 on the inner surfaces of the opposing side walls. 12 is fitted, and the hood 10 slides in the direction of the arrow in FIG. 2 using the protrusion 12 as a guide.

In FIGS. 1 and 2, the hood 10 is located on the movable box 4, and by sliding the hood 10 forward from this state, the operating section 7 is moved to the hood 1 as shown in FIG.
0, and the operation part 7 will not be damaged when not in use.

In addition, in the state shown in FIGS. 1 and 2, the lock release button 9
When is pressed, the movable box 4 rotates as described above, and the screen of the cathode ray tube 3 appears outside the cabinet 1 as shown in FIG.

Then, as shown in FIG. 6, by sliding the hood 10 forward and causing its tip to protrude beyond the tip of the cathode ray tube 3, it can function as an original hood.

The present invention is intended to provide a click feeling when the hood 10 is slid, and the structure of the click mechanism is simplified so that it can be manufactured at low cost.

As shown in FIGS. 7 and 8, in this example, a sheet made of plastic such as vinyl chloride is constructed with a flat part and bent parts continuous on both sides of the flat part, and the entire elastic sheet has elasticity. 13, and a protrusion 14 is integrally provided in the center of the flat part, and this elastic sheet 13 is fitted between a pair of L-shaped ribs 15, 15 provided on the inner surface of the hood 10.

At this time, the ribs 15, 15 are arranged in series in the sliding direction of the hood 10, and the elastic sheet 13 is inserted into the ribs 15, 15 from a direction perpendicular to the sliding direction of the hood 10.
Fits in between.

On the other hand, the protrusion 1 of the elastic sheet 13 is provided on the top surface of the movable box 4.
A large number of grooves 16 into which the hoods 4 fit are provided at regular intervals in the sliding direction of the hood 10.

Therefore, by sliding the hood 10 forward or backward, a clicking sound is generated between the protrusion 14 and the groove 16.

In addition, in FIGS. 1 to 5, reference numeral 17 denotes an operating portion of the hood 10, which is composed of a continuous uneven portion.

Further, 18 is a speaker.

In order to generate a click feeling in this way, the conventional method has been to use a ball bearing and a spring, and to fit the ball bearing into the groove by the elastic force of the spring, but this method is expensive and
There is also the problem that the number of parts increases, making the configuration complicated, but according to the present invention, only the elastic sheet 13 needs to be added, so the configuration can be simplified and the cost can be reduced. be.

In the above embodiment, the hood of a television receiver in which the cathode ray tube can be freely retracted from the cabinet has been described as an example, but the present invention is of course not limited to this, and can be applied to other configurations. It is.

As explained above, according to the present invention, an elastic sheet is attached to the hood, and a large number of grooves that fit into the protrusions of the elastic sheet are provided in the box supporting the hood, so that a click feeling is felt when sliding. In addition, the structure itself is simple and inexpensive because it only uses a plastic elastic sheet, and is extremely valuable in practice.
