Title:
DISPLAY DEVICE CEILING STORAGE APPARATUS HAVING EXTENSION ARM
Document Type and Number:
WIPO Patent Application WO/2017/099281
Kind Code:
A1
Abstract:
Provided is a display device ceiling storage apparatus which has an extension arm which is disposed on the top of a frame for fixing a display device so as to extend and contract; which couples a band or string (hereinafter referred to as "band"), coupled to an upper connection point and a lower connection point, to a pulley so as to install the frame together with a balance hung on the pulley; which couples a wheel of the frame which is positioned on the top of the frame to a track of a guide track; which, when the frame is deployed to a viewing position, if the pulley rotates, enables the band coupled to the lower connection point to be pulled by means of the rotational force and enable the band coupled to the upper connection point to be released so that the ratio of the lengths of the bands of both sides varies, the center of mass of gravity of the frame supported by the bands of the both sides varies, and thus a phase shift of a display plate from a vertical direction to a horizontal direction is carried out; which is operated by the principle of a second class lever by using a coupling point of the guide track and the wheel as the fulcrum and using the lower connection point as the effort; which enables the wheel on the top of the frame to follow the guide track and limit the movement of the frame by the regulation of a support so that the frame moves to an internal space of a ceiling, and thus is phase-shifted from the viewing position to a storage position and then is stored; and which is deployed to the viewing position by a reverse process.
