KR-20260066252-A - angle adjusting blackboard

Abstract

The present invention relates to an angle-adjustable whiteboard, specifically an improved whiteboard that allows a user to freely adjust the angle of the whiteboard to ensure good visibility from various positions. To address the inconveniences of existing whiteboards, an angle adjustment device and a fixing device are added to the whiteboard, enabling the user to adjust the whiteboard to a desired angle and securely fix it. This invention can be utilized in schools and various educational settings, enhancing learning effectiveness and increasing user convenience by solving the problem of poor visibility of the blackboard from the front seats. The angle adjustment mechanism can be implemented using a lever, a rotary axis, or a hydraulic adjustment method, and a locking mechanism ensures that the adjusted angle is maintained without wobbling. Furthermore, due to its modular structure, this invention is applicable to blackboards of various sizes and includes safety features, allowing even children and the elderly to use it easily. The core objective of the present invention is to provide an angle-adjustable whiteboard with significantly improved convenience, stability, and usability.
