Description

The present invention relates to a display device lifting / lowering frame that can be stopped at an arbitrary position, and more particularly, to a display device lifting / lowering frame that is used for installing a display device and can be stopped at an arbitrary position that is compact and convenient for lifting operation.

Display devices (displays, white boards, blackboards, or other flat electronic products) are often installed using an installation cabinet, or using a hanging arm or support arm to provide stability and convenience for installation. Suspend the display device to achieve the convenience of use.
However, these installation cabinets cannot be moved and operated above and below the display device to adjust the viewing position. With the hanging arm and support arm, if there is not a relatively large space, the upper and lower positions are high. You can't adjust it.
Therefore, it is inconvenient in use and operation to install a display device whether to use an installation cabinet or to use a hanging arm or a support arm.

In order to solve the above-mentioned drawbacks, the applicant has developed a lifting support frame disclosed in Patent Document 1.
The elevating support frame includes a leg frame, and a traction mechanism and a hook movable mechanism are installed on the leg frame.
The traction mechanism is mainly composed of a traction disk, a pulley, and a spring.
Moreover, a spiral part is installed on the traction board.
A display device can be placed on the hook moving mechanism, and the hook moving mechanism includes a pulling wire.
The traction wire is wound around a traction disk and a pulley of the traction mechanism and is installed to pivot with a spring.
As a result, when the display device is moved up and down, the rotation of the traction disk is driven and the spring is moved to form a force balanced state, thereby achieving a stop effect at an arbitrary position steplessly.

The above-described lifting support frame has the effect of stopping at any position of stepless lifting, but the leg frame, the traction mechanism, and the hook moving mechanism are complicated in components and structure, so at least two people are required when assembling. It cannot be completed.
At the same time, since the spiral part is installed in a projecting manner on the rear side of the traction board, the volume of the elevating support frame is relatively large and looks very thick when viewed from the side.
Therefore, it cannot be installed on the wall, which is inconvenient and limited in use.
The present invention has been made in view of the above-described drawbacks of the conventional lifting support frame.
