Claims (3)

1. A main frame (100) installed on a wall, and A left-right moving frame (200) installed on the main frame (100), and A vertical movement frame (300) coupled to the above-mentioned horizontal movement frame (200), and A chalkboard capable of vertical and horizontal movement fixed by a weight, characterized by being composed of a chalkboard (400) installed on the above-mentioned vertical movement frame (300).
2. In paragraph 1, The above-described left-right moving frame (200) is characterized by wheels (201) installed on the upper and lower parts, and the wheels (201) are inserted into the rail (110) formed on the main frame (100) to move left and right, and is a whiteboard capable of moving up, down, left, and right, fixed by a weight.
3. In paragraph 2, The above-mentioned vertical movement frame (300) is installed on the horizontal movement frame (200) and is characterized by being moved up and down by a wire (1), and not moving up or down unless the user moves it by a weight (20), thereby being fixed by a weight and capable of vertical and horizontal movement.

Description

A blackboard that can move up, down, left, and right and is fixed with weights The present invention relates to a whiteboard capable of moving up, down, left, and right, which is fixed by a weight. More specifically, the invention relates to a whiteboard capable of moving up, down, left, and right, which is fixed by a weight that allows the whiteboard, which is coupled to a frame, to move easily in any direction. Generally, blackboards are mounted on walls in places such as schools or classrooms for writing purposes. However, since conventional blackboards are fixed to the wall, it was difficult for short users to write on the upper side of the board, and if the height of the board was too low, it was difficult for listeners to see the written content due to the person in front of them. To solve these problems, a whiteboard capable of being raised and lowered vertically is being implemented with various options. As for prior art regarding a whiteboard capable of being raised and lowered, Public Patent Publication No. 2003-0028643 discloses a whiteboard for video education installed on the front wall of a classroom in a school or academy, etc., for use as a writing board for education, characterized by comprising: a frame part in which a central frame is installed in the center of the whiteboard and side frames are installed on both sides of the central frame so as to be detachable at the boundary; a monitor installed on the central frame to enable various video education; a writing board having a wipeable writing surface installed on the side frames to be positioned on both sides of the monitor; and a raising and lowering means for raising and lowering the central frame from the side frames to adjust the height of the monitor. Another prior art is disclosed in Public Patent No. 1997-0010809, which comprises a frame unit in which a central frame is installed in the center of the front wall of a classroom, etc., and side frames are installed on both sides of the central frame so as to be detachable at the boundary therefrom; a main board installed facing forward on the central frame of the frame unit; an auxiliary educational member located on both sides of the main board and positioned to move toward the front of the main board while wrapped by the side frames; a lifting means for moving the central frame to which the main board is attached up and down; and a positioning means for fixing the lifting position of the main board so as to coincide with the position of the auxiliary educational member. In this case, the positioning means comprises a support plate attached to the central frame; a lever to which an axle pin is hinge-connected so as to be rotatable to the support plate; a pair of rod members that extend to the boundary position of the side frames and respond symmetrically according to the rotational operation of the lever connected to the axle pin of the lever by a connecting element; and a guide member supporting the end of the rod member. A lifting position determining device for a lifting and lowering opening and closing board is disclosed, characterized by being configured such that a fixing member is fitted and fixed to the boundary position of the central frame on the side frame, and a locking hole is formed so that the above-mentioned rod member is fitted and hooked. However, conventional technologies had the problem that the blackboard could only be raised and lowered, making it impossible to easily move it up, down, left, and right.
