Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus that prevents a television receiver, a personal computer, or the like from falling over due to vibration or impact when installed in a predetermined place.
[0002]
[Prior art]
Since the center of gravity of the television receiver is shifted to the front side due to its structure, it is easy to fall to the front side when an earthquake occurs or when some impact is applied. In general, the television receiver is often placed on a mounting table such as a table having an appropriate height, and if it falls down, it falls from the table base and not only damages the television receiver. , Damage the items placed near the table. Also, if a person is nearby in the event of a fall, you will be injured. In particular, television receivers in recent years have become larger, and losses due to falling are large.
[0003]
By the way, various techniques have been developed in the past for preventing the fall of a television receiver. For example, a "television receiver overturn prevention device" according to Japanese Patent Laid-Open No. 9-37191 is a string in which one side is fixed to a wall surface of a house or the like and the other side is hooked on a bowl-like body of a back cover of a television receiver By holding the television receiver, it is possible to prevent overturning. Further, the television receiver can be prevented from being overturned by inserting and fixing a band with a rack attached to the band insertion hole of the back cover.
[0004]
However, in such a method, a fastening tool for fastening one end of the string to the wall surface of the room must be attached, and scratches remain on the wall surface. Of course, it is also in the way that a string to be stretched is interposed between the wall surface and the television receiver.
[0005]
In addition, “a fall prevention device and a stationary display device equipped with the fall prevention device” disclosed in Japanese Patent Application Laid-Open No. 11-9373 has a large screen and a thin AV device that falls due to vibration and shock. The device to prevent is made possible in a state of good design. Therefore, an iron ball is placed on a piston that passes through a cylinder integrally formed with a tray that is fixedly supported in the device, and the rod supported on the rotating shaft at the lower end of the piston is counterclockwise against the bias of the rod spring. In this state, the fall prevention lever and the stop lever integrated with it are locked to the stopper part of the rod and stored in the device, but the iron ball falls to the tray due to vibration etc. Then, the rod rotates clockwise by the spring force of the rod spring to disengage from the stopper lever, and the overturn prevention lever rotates clockwise by the biasing force applied to the rotating shaft, and protrudes out of the device to display. Support to prevent falling.
[0006]
However, in this apparatus, when an impact such as vibration is detected, the device only protrudes as a fall prevention means, and there is no effect when the display apparatus slides down from the mounting table. In other words, there is no problem if the display device is installed in a large place such as the floor surface, but when it is placed at a position higher than the floor surface, such as on a chiffon or on a TV stand, there is no fall prevention means. If there is no contact portion on the front side even when the device is extended by operating, the display device falls. In addition, the structure of the apparatus is complicated and the manufacturing cost is very high. In addition, since a plurality of parts operate in conjunction with each other by detecting vibrations and shocks, the reliability is low, and it may not work when used for a long time or in a bad environment.
[0007]
