Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and more particularly to an improved detachable panel of a housing.

2. Description of the Related Art FIG. 7 shows a mounting structure of a panel constituting a housing of this conventional television receiver, 21 is a cabinet of the television receiver, 22 is a front panel covering the periphery of a CRT, 23 Is a screw for fixing the front panel to the cabinet 21, 24 is a back cover, 25 is a back cover 24
Screw to fix the cabinet to the cabinet 21, 26 is the side panel,
27 is a side panel set screw. FIG. 8 is a sectional view showing a portion where the front panel 22 is fixed to the cabinet 21 with screws 23 in the conventional example.

In the conventional panel mounting structure configured as described above, when the panel 22 is to be replaced, the back cover 24 is removed, the screws 23 are further removed from the inner surface of the housing, the panel 22 is removed, and another panel is mounted. You have to do the same again to do that. The side panel 26 is attached by screws 27.

However, in the above-described configuration, when the front panel 22 is to be replaced, the work is time-consuming because the mounting is performed by the screws 23 from the inside of the housing, and the work is performed inside the television receiver. Therefore, there was a problem that it could only be done by service personnel or other specialists. Also, if the internal parts are in the way when removing the screw 23, the parts must also be removed, which requires more work time.

Replace the side panel 26 with external screws 27
Work is required, but requires tools and takes time. Also, because the screw head is visible from the outside, the design is damaged.

In view of the above, an object of the present invention is to provide a structure that allows a user to easily attach / detach a design change / protection cover without using a tool by attaching / detaching a panel from outside without removing a back cover. And

Means for Solving the Problems In order to solve the above problems, a detachable panel device of the present invention is provided with cylindrical projections at four corners on the back surface of the panel, and the projections are inserted and held in a receiver main body. Four elastic parts, such as rubber, having a hole diameter slightly smaller than that of the projections are provided.

In addition, for the remote control light receiving unit and display lamp provided on the receiver body, an opening that satisfies the maximum light receiving angle is provided on the front of the remote control light receiving unit on the detachable panel side, and the front of the display lamp is made of colorless transparent parts, The light-entering surface and side surfaces were mirror-finished to guide the light of the television receiver body to the surface of the detachable panel, and the surface was roughened and irregularly reflected.

Function The present invention has a configuration in which, when the projection of the panel is inserted into the rubber hole provided in the main body of the receiver, the diameter of the projection is slightly larger than the diameter of the hole, so that the panel is held by the elasticity of the rubber. The panel can be attached and detached with one touch without using a tool.

In addition, by providing an opening having a size that satisfies the light receiving angle at the front of the remote control light receiving section of the panel, the remote control can be used even when the panel is attached. Furthermore, the light of the display lamp of the television receiver body was led to the front of the detachable panel through the transparent and mirror-finished parts so that the lighting of the lamp could be confirmed even with the panel attached. Furthermore, roughening the surface makes the light diffusely reflected, increasing the angle at which lighting can be confirmed.

Embodiment 1 FIG. 1 shows a mounting state of a detachable panel according to a first embodiment of the present invention, and FIG. 2 shows a sectional view at the time of mounting. 1 and 2, 1 is a television receiver main body, 2 is a CRT, 3 is an elastic rubber having a hole for holding a detachable panel, 4 is a remote control light receiving section,

Is an opening provided in the front of the remote control light-receiving unit, and 9 is a transparent acrylic that guides the light of the standby lamp to the front of the detachable panel to display the light.

FIG. 3 shows an embodiment in which the detachable panel is a front protective cover of the CRT. 10 is a cover to protect the CRT. FIG. 4 shows an embodiment in which a detachable panel is attached to a side surface or a top surface.
11 and 12 are detachable panels for the top of the side, and 13 is rubber that attaches and holds the detachable panel for the top of the side to the body. FIG. 5 is a sectional view showing a structure for guiding the light of the standby lamp to the surface of the detachable panel. 14 is a front panel of the television receiver body, 15 is a transparent sheet for protecting the LED, 16
Is an LED, 17 is a printed circuit board. FIG. 6 is a sectional view showing that a remote control can be used even when a detachable panel is mounted.
18 is a light receiving element, and 19 is a smoke sheet covering the opening.

The operation of the detachable panel device of this embodiment configured as described above will be described below.

In FIG. 1, the cylindrical projection 7 provided on the detachable panel 6 covering the periphery of the CRT has a rubber 3 having a hole diameter slightly smaller than its diameter.
2, the panel 6 is held by the elasticity of the rubber 3 as shown in FIG.

FIG. 3 shows a state in which the cylindrical projection 7 provided on the detachable panel 10 covering the front surface 3 of the CRT is mounted on the television receiver main body by being inserted into a hole of the rubber 3 having a slightly smaller hole diameter. Indicates protection of the CRT.

FIG. 4 shows a state in which the cylindrical projection 7 of the detachable panel 11 provided on the side surface or the top surface of the television receiver is inserted by being inserted into the hole of the rubber 13 of the main body, thereby protecting the housing and changing the design. Can be made easier.

Further, FIG. 5 shows that the front part of the display lamp is composed of a colorless and transparent component 24, one end of which is close to the light source, the side of the component is mirror-finished, and the reflection-side end is illuminated by utilizing light reflection. The lighting of the lamp can be confirmed even with the panel 6 attached.

FIG. 6 shows that the opening 8 is provided in a range slightly larger than the light receiving range so that the signal of the remote control transmitter can be received when the panel 6 is mounted.

As described above, according to this embodiment, the mounting and dismounting of the panel is performed by providing a cylindrical projection on the back surface of the panel and providing elastic rubber having a hole diameter slightly smaller than the diameter of the projection on the main body side. Can be facilitated. An opening is provided on the front surface of the remote control light-receiving unit, and the front surface of the display lamp unit is made of a transparent component whose side surfaces are mirror-finished.

Effect of the Invention As described above, the present invention provides a projection on the back of the panel and a rubber for holding the panel of the television receiver main body, thereby enabling one-touch attachment and detachment of the panel without using a tool. The protective cover can be attached and detached. In addition, an opening is provided in the front of the remote control light-receiving unit, and the front of the display lamp is made of transparent parts with mirror-finished sides, so that the remote control can be used whether the panel is installed or removed, and the lamp display can be checked.
