Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a stand device for display equipment such as a display television used in a computer, and in particular to a stand device for variably adjusting the installation angle of the display surface of the equipment. The present invention relates to a stand device that enables the use of stand devices.

[Background technology and its problems]

Conventionally, stand devices for televisions (television receivers) include a base and a cradle that is rotatable in the front and rear directions with respect to the base, and the screen of the television set on the cradle. It is known that the tilt can be adjusted upward or downward.

As an example of this type of stand device, there is one in which a gear mechanism is provided between a base and a pedestal, and the pedestal can be rotated in the front and rear directions on the base via this gear mechanism. However, although the stand device has the advantage of being able to hold the television set on the cradle at a predetermined angle of inclination through the meshing relationship of the gears without using a special locking mechanism. However, the installation angle of the television screen is limited by the pitch of the gears, and the disadvantage is that the installation angle of the television screen cannot be adjusted to an arbitrary angle.

In addition, as another example of a conventional stand device, a spherical recess is provided in the base, and a spherical part formed on the lower surface of the holder is slidably fitted into this recess, thereby allowing the holder to be mounted. There are some that can be rotated back and forth. However, although the stand device has the advantage of being able to adjust the installation angle of the TV screen placed on the cradle to any angle, it holds the TV at a predetermined tilt angle. In order to do this, a holding device for fixing the cradle to the base with screws or the like is required, making adjustment of the installation angle of the television screen complicated.

Further, in the stand device, when the holding device is released from the lock state in order to return the TV held at a predetermined tilt angle to a horizontal state, the TV suddenly returns to rotation, which is dangerous. In particular, when the above-mentioned television is a large one equipped with a 20-inch cathode ray tube, the speed at which the television recovers is large and becomes very dangerous. Therefore,
Although it may be possible to provide a buffer mechanism such as a damper to reduce the return speed of the television set, the disadvantage is that the structure of the stand device becomes complicated and the cost increases.
