CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Taiwanese application No. 94136286, field on Oct. 18, 2005. All disclosure of the Taiwan application is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a display device. More particularly, the present invention relates to a display device with detachable cover.
2. Description of the Related Art
In recent development, the flat panel display (FPD), such as liquid crystal display (LCD), organic electro-luminescent display (OELD) or plasma Display panel (PDP), has gradually been the main display product in the market.
Taking the PDP as the example, based on the manner of use, it can be categorized into a back-hanging type being hanged on a wall or a standing-frame type being standing on a stage. When the PDP is standing on the stage by a standing frame, the PDP needs a TV stand hole for plugging the stand frame into the TV stand hole. However, when the PDP in use is hanged on the wall, it needs to use a cover for covering the TV stand hole, so as to maintain the appearance of the PDP and satisfy the safety requirement for the product.
The conventional method is using screws to fix the cover onto the PDP for covering the TV stand hole. However, the method using the screw for fixing the cover onto the PDP not only causes the difficulty in assembling and detaching, but also consumes time in assembling the cover, resulting in increase of fabrication cost. In addition, the material for the PDP is metal, so it is difficult to form a protruding member in the TV stand hole for hooking by a hook. This also causes difficulty for the cover to be buckled on the display device at a protruding member by the conventional hook.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a perspective view illustrating a display device according to a preferred embodiment of the present invention. In FIG. 1, the display device 100 is, for example, an LCD display device, an OELD display device, a PDP display device, or other type of display device. The display device 100 includes a main body 110 and at least one cover 120. The main body 110 has several TV stand holes 112, and each of the TV stand holes 112 has a sidewall 112 a and an inner wall 112 b. The cover 120 is detachably disposed on the main body 110, and is used for covering the TV stand hole 112.
FIG. 2 and FIG. 3 are perspective views illustrating the cover of FIG. 1 from different viewing directions. Referring to FIGS. 1, 2 and 3, the cover 120 includes two buckling parts 122, two lugs 124, and a removable portion 126. The two buckling parts 122 are located at opposite two sides of the cover 120, preferably at left and right sides. Each buckling part 122 includes a buckling main part 122 a and a buckling surface 122 b. The buckling surface 122 b is coupled with the buckling main part 122 a at a side far from the cover 120, and the buckling surface 122 b is implemented by facing to the inner wall 112 b of the TV stand hole 112. The two lugs 124 and the removable portion 126 are located at the other opposite two sides of the cover 120. In this embodiment, the cover 120 can be made of, for example, plastic or metal. Particularly, the buckling part 122 can be formed from the elastic plastic. As a result, the buckling main part 122 a is an elastic body being thin and elastic. Referring to FIG. 3, in this embodiment, the buckling main part 122 a is perpendicularly protruding out from the cover 120. The buckling surface 122 b can be a slant surface, and preferably a rectangular slant surface. Referring to FIG. 1 again, the buckling main part 122 a of the cover 120 can enter the corresponding TV stand hole 112. In addition, the cover 120 is buckled into the TV stand hole 112 of the main body 110 via an elastic force from the buckling part 122 and a friction force from the buckling surface 122 b, so that the TV stand hole 112 is covered.
In more detail, the buckling part 122 of this embodiment of the present invention enters the corresponding TV stand hole 112, and contacts with the inner wall 112 b of the main body 110 The inner wall 112 b is an inner surface of the main body 110. In other words, when an user wants to assemble the cover 120 to the main body 110, the buckling part 122 is pre-aligned to the corresponding TV stand hole 112. Then, the buckling main part 122 a of the cover 120 is applied with a force, so as to shift the buckling surface 122 b of the buckling main part 122 a along the sidewall 112 a of the TV stand hole 112. The buckling main part 122 a is deformed and an elastic force is generated. After the buckling part 122 enters the corresponding TV stand hole 112, the buckling main part 122 a recovers back to the original shape, due to the elastic force of the buckling main part 122 a. As a result, the buckling main part 122 a expands and buckles on the inner wall 112 b. In addition, due to the friction between the buckling surface 122 b and the sidewall 112 a, the buckling part 122 is stably buckled into the TV stand hole 112 of the display device 100.
In accordance with the foregoing descriptions, in order to allow the cover 120 to be more easily assembled to the main body 110, the cover 120 is formed with several lugs 124 thereon. The lug 124 is used for allowing the cover 120 to be pre-aligned to the corresponding TV stand hole 112. Therefore, the buckling part 122 enters the TV stand hole 112 more easily for buckling onto the inner wall 112 b of the main body 110. In more detail, before the buckling part 122 is buckled to the main body 110, the lug 124 enters the TV stand hole 112 and gets in contact with the inner wall 112 b of the main body 110. Then, a force is applied on the buckling main part 122 a of the cover 120, so that the buckling part 122 enters the corresponding TV stand hole 112. Then, the deformed buckling part 122 recovers back to the original shape and is buckled on the inner wall 112 b. In association with the friction from buckling surface 112 b, the cover 120 is stably buckled into the TV stand hole 112.
In addition, in order to allow the cover 120 to be easily detached from the main body 110, the cover 120, for example, further includes a removable portion 126. The removable portion 126 is disposed on the cover 120 at a side opposite to the lug 124. When the user wants to detach the cover 120 from the main body 110, the user only needs to apply a force via fingers to move the removable portion 126, resulting in a separation between the buckling surface 122 b of the buckling part 122 and the inner wall 112 b. The user needs no additional tools to detach the cover 120 from the main body 110. The removable portion 126, preferably, is a groove. Certainly, a pulling ring (not shown in drawings) or other structure are also available for the removable portion 126 for allowing the cover 120 to be easily separated from the main body 110.
In summary, the display device of the present invention includes a cover with buckling part, and the cover is assembled to the main body for covering the TV stand hole. The buckling mechanism used by the buckling part is the elastic force due to deformation and the friction force due to the contact between the buckling surface and the inner wall. In addition, since the cover has the removable portion, the user can just use the finger to move the removable portion, so as to applying force thereon and directly detach the cover from the main body without additional tool. In other words, the present invention has the advantages of being easy assembling, simple detaching, and saving the assembly cost and time.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing descriptions, it is intended that the present invention covers modifications and variations of this invention if they fall within the scope of the following claims and their equivalents.
