July 16, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- Compal Electronics, Inc. (Taipei, TW) has been issued patent number 8763977, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Huang, Chun-Ming (Taipei, TW); Yen, Shih-Hsiung (Taipei, TW); Lin, Jian-Yu (Taipei, TW).

This patent was filed on July 17, 2012 and was published online on July 1, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The present disclosure relates to a stand for a display device, and more particularly to a stand for a display device capable of adjusting and limiting angles.

"In recent years, liquid crystal displays (LCDs) have been extensively used in various consumer electronic products and are gradually replacing cathode ray tubes (CRTs). The replacing of CRTs with LCDs is occurring due to the fact that LCDs have the advantages of high definition, small volume, low weight, low radiation, and low power consumption compared with CRTs. LCDs are used, for example, in most televisions, monitors, cellular phones, and portable computers on the market. Therefore, LCDs have become indispensable electronic products for work or pleasure.

"An LCD may include a stand. The stand may be fixed on a backboard of the LCD, such that the LCD can be placed on a table and maintained at a particular inclination by utilizing the stand. By adjusting the inclination, users can see images displayed by the LCD utilizing an optimum viewing angle. The stand is often connected to the backboard of the LCD by a hinge structure, such that the stand can be pivoted on the backboard of the LCD, and users can adjust the included angle between the stand and the backboard of the LCD as desired.

"When the LCD needs to be packaged or moved to another place, users may press the stand to a position substantially parallel to the backboard of the LCD to allow for convenient packaging or moving. However, the material of the hinge structure is metal, and the material of the housing of the stand is plastic. When the stand is pressed to the position parallel to the backboard of the LCD, the stand is easily pivoted on the backboard of the LCD by an excessive amount due to too much force being exerted by a user, such that the stand may be damaged.

"Furthermore, with the conventional configuration, when a user adjusts the included angle between the backboard of the LCD and the stand or moves the LCD, the stand may be completely folded inadvertently when an excessive force is used by the user when pushing the LCD. As a result, the LCD may collapse and be damaged."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "An aspect of the present invention is to provide a stand for a display device.

"In an embodiment of the present invention, a stand for a display device includes a housing having an accommodating groove, a hinge structure including a first board and two second boards, and a latch flexibly placed on the housing and aligned with the first board. The first board is fixed on a backboard of the display device and has a positioning groove. The two second boards are rotatably connected respectively to two ends of the first board and each is fixed on the housing. The latch includes an operation portion and a fastening portion. The operation portion is exposed through the accommodating groove. The fastening portion is selectively engaged with the positioning groove by releasing a spring force of a spring connected to the latch. An included angle is formed between the housing and the backboard of display device when the fastening portion is engaged with the positioning groove. When the operation portion is moved in a direction away from the first board, the fastening portion is disengaged from the positioning groove by compressing the spring connected to the latch, such that the housing is pivoted to a position parallel to the backboard of display device.

"In an embodiment of the present invention, the positioning groove includes a first sidewall, a second sidewall, and a groove bottom. When the fastening portion is located in the positioning groove, the fastening portion is selectively abutted against the first sidewall, the second sidewall, or a portion of the groove bottom located between the first and second sidewalls.

"In an embodiment of the present invention, the fastening portion has a contact surface, and the first board has an axle center. When the contact surface is abutted against the first sidewall, the contact surface is located on a connecting line formed by the first sidewall and the axle center.

"In an embodiment of the present invention, the length of the accommodating groove is greater than the length of the operation portion, such that the operation portion is movable in the accommodating groove.

"In an embodiment of the present invention, the stand further includes a latch fixing base located between the latch and the housing. The latch fixing base is fixed on the housing and includes two extending wings respectively fixed on the two second boards.

"In an embodiment of the present invention, the stand further includes a strengthening board fixed on the housing, such that the two second boards, the latch fixing base, and the latch are sandwiched between the strengthening board and the housing.

"In an embodiment of the present invention, the latch fixing base includes a hollow pillar, the strengthening board has a fixing hole, and the hollow pillar is aligned with the fixing hole.

"In an embodiment of the present invention, the stand further includes a fixing member extending through the fixing hole and coupled to the hollow pillar.

"In an embodiment of the present invention, the latch fixing base includes a stop wall protruding into the positioning groove for abutting against the latch.

"In an embodiment of the present invention, the latch further includes a cushion body fixed on the fastening portion for abutting against the first sidewall, the second sidewall, or the groove bottom.

"In an embodiment of the present invention, the material of the cushion body includes plastic or rubber.

"In the aforementioned embodiments of the present invention, the latch is flexibly placed on the housing and the operation portion is exposed through the accommodating groove. Therefore, the position of the latch can be moved by the operation portion. In addition, the fastening portion can be selectively abutted against the first sidewall, the second sidewall, or the groove bottom, such that the different included angles can be formed between the housing and the backboard of display device. When the operation portion is moved in the direction away from the first board, the fastening portion can be disengaged from the positioning groove. At the same time, the housing can be pivoted to a position substantially parallel to the backboard of display device.

"As a result, when the stand for a display device is pivoted to the position parallel to the backboard of the display device, the stand is not easily pivoted on the backboard of the display device in an excessive manner due to the exertion of a disproportionate amount of force by the user. Hence, the stand is not easily damaged when pivoted to such a position parallel to the backboard of the display device. Furthermore, when adjusting a viewing angle of the display device or when moving the display device, the stand is not easily folded due to an excessive force being applied to the display device. Hence, the display device can be prevented from collapsing and being damaged."
