Description

TECHNICAL FIELD The present invention relates to a method of mounting a housing , a display device, a flat-screen television, and a rear cabinet.

In recent years, flat-panel televisions are becoming larger. Along with this, the size of a housing configured by a chassis and a rear cabinet for housing a display device such as a display is also increasing. When fixing the rear cabinet to the chassis, etc., problems of strength and warping of the rear cabinet due to thermal expansion occurred, so in the past, many screws were used to fix the rear cabinet. . However, endlessly increasing the number of screws is not realistic for reasons such as an increase in manufacturing cost. Therefore, as shown in Patent Document 1, a structure is also disclosed in which the rear cabinet is attached to the chassis by means of a mounting structure formed on the outer peripheral edge of the rear cabinet and the outer peripheral edge of the chassis.

Japanese Patent No. 5771657

However, as the size of the chassis and the rear cabinet further increased, it became necessary to reduce the thickness of the outer peripheral edge of the rear cabinet and the outer peripheral edge of the chassis in order to reduce the weight of the flat-screen television. Therefore, if the mounting structure is formed on the thinned outer peripheral edge of the rear cabinet and the outer peripheral edge of the chassis, there arises a problem that sufficient fixing strength of the rear cabinet cannot be ensured. In addition, there has been a problem in that the back cabinet warps due to thermal expansion, and the joining portion between the back cabinet and the chassis in the housing floats.

Therefore, as a means for solving the above problems, a housing according to the present invention is provided around an object to be accommodated, and has a chassis provided on its outer surface with an inclined surface that widens from the back surface to the front surface of the object to be accommodated; a rear cabinet attached to cover the rear surface of the stored object from the outside of the chassis, the engaging portion protruding from the inclined surface, and the claw portion provided on the inner side surface of the rear cabinet. and, by locking the claw portion to the locking portion, the rear cabinet is mounted inside the outer peripheral edge of the rear cabinet.

Moreover, it is preferable that the locking portion is an end side of a reinforcing plate fixed to the inclined surface, and the end side is positioned on the inclined surface.

In addition, instead of the end side of the reinforcing plate, the locking portion is arranged so that the part of the chassis that constitutes the inclined surface is more inclined toward the inclined surface than the rear side, regardless of the presence or absence of the reinforcing plate. It may be configured by protruding in a shape that is greatly warped by bending.

Further, it is preferable that the claw portion is formed by forming a hook piece on an elastic body protruding from the inner surface of the rear cabinet.

Furthermore, the elastic body forms a space between the legs which stand apart from each other in parallel to the outer peripheral edge of the rear cabinet and the legs which are connected to the inner surface of the rear cabinet. It is also preferable that the connecting portion is formed in a bridge shape, and the hanging piece is formed in the connecting portion.

Moreover, it is preferable that the object to be housed is an image display unit and the display device is characterized by comprising the housing. The display device can display images and videos on the image display section.

Further, a flat-screen television including the display device is preferable.

Further, as a means for solving the above-described problems, a method for mounting a rear cabinet according to the present invention provides a chassis which is provided around an object to be accommodated and has an inclined surface on the outer surface which widens from the back to the front of the object to be accommodated. and a rear cabinet attached to cover the rear surface of the stored object from the outside of the chassis, and a locking portion provided projecting from the inclined surface and provided on the inner side surface of the rear cabinet. and a claw portion that is mounted on the housing, and a method for attaching the rear cabinet inside an outer peripheral edge of the rear cabinet by engaging the claw portion with the engaging portion. .

According to the present invention, the rear cabinet can be attached to the chassis inside the outer peripheral edge of the rear cabinet without forming a mounting structure on the outer peripheral edge of the rear cabinet or the outer peripheral edge of the chassis.

As a result, it is possible to prevent the joint portion between the rear cabinet and the chassis from being lifted even in a housing having a rear cabinet and a chassis that are enlarged in size.

Furthermore, even if the enclosure has a large-sized rear cabinet or chassis, it is possible to realize a display device in which the joint portion between the rear cabinet and the chassis does not float, or a flat-screen television equipped with the display device. .
