Description

Movable stand-type blackboard}

The present invention relates to a blackboard that is a tool for teaching in a school or academy, and the like, and in particular, a vertical frame is installed on each of two lower frames, each of which has casters installed at the bottom of both sides for easy movement, and then the top of the vertical frame. It is inserted to allow height adjustment by the height adjustment hole formed on the fixing rod on one side of the connecting rod, and the other side of the connecting rod is fixed to the board of predetermined size by holding the handle according to the environment. It is about blackboards that can improve students' concentration by allowing them to move and educate.

In general, the blackboard has been used to explain the contents of the education by the user taking notes at the place where the education such as school or academy is conducted, and the built-in blackboard and the removable blackboard have been used as a representative. Chalkboard was used as a surface member to bond the wood to the back in order to prevent deformation of the iron plate, which is the surface member, and then fixed to a specific position (wall) inside the classroom or classroom, the blackboard is moisture Easily deformed (twisted) by the shortened lifespan shortens the need for frequent replacement, as well as the cost burden, and the built-in blackboard is not possible to move the position always distance between the user and the student Many problems, such as poor learning ability and distraction Problems have arisen.

On the other hand, in order to solve the problems described above, the use of a number of types of blackboards or boards has recently been increased, and among them, the conventional removable blackboard shown in FIG. A pair of lower frames 101 and 101 'integrally provided with two casters 102 and a vertical frame 103 and 103' having a predetermined length in the center of the pair of lower frames 101 and 101 '. It is fixed integrally, but the upper portion of the pair of vertical frame 103 (103 ') is formed with the insertion hole 104 and then formed of a predetermined size and provided with a blackboard 100 formed with a fixing hole 105 in the center of both sides Thus, a movable blackboard 100 in which the rotating shaft 106 is closely inserted and fixed in the state where the insertion hole 104 and the fixing hole 105 are aligned is proposed.

In addition, by galvanizing the steel plate, which is a surface member of the blackboard 100, or by enameling, prolonging the life of the blackboard 100, as well as the characters represented on the surface of the blackboard 100 are clearly recognized from a distance. It is possible to clear the letters represented above.

However, as described above, the blackboard 100 arranged on the upper side of the vertical frame has a problem that it is not easy to write by a user with a large or small height because the height is not fixed and fixed to a certain height. The pair of lower frames 101 and 101 'could not support the heavy load of the blackboard 100 fixed to the vertical frames 103 and 103 ′ of the blackboard 100 so that they fell frequently during movement. In order to shorten the life of the expensive blackboard 100 by damaging and to move the movable blackboard 100, two or more persons must face each other to correspond to each other and hold a pair of vertical frames 103 and 103 ', respectively. In the state of dragging from the front to push from the back to the place to use the movement time is very long, the position of holding the vertical frame 103 (103 ') is inconvenient, there is always a risk of safety accidents, etc. This problem occurred.

Therefore, in order to improve the above problems, the present invention is provided on the upper both sides of the pair of lower frames integrally installed on the bottom of the plurality of casters for enabling the movement of the blackboard, each height adjustment is installed on the upper side The upper and lower width adjustable supports are fixed to the two pairs of vertical frames, which are rolled up integrally, one curved frame is inserted into one pair of vertical frames, and the other vertical pair of vertical frames is inserted and fixed. One end of the curved connecting rod is provided with a movable adjustable width of the handle and the pair of vertical connecting rod to provide a movable board that is fixed to the blackboard of a predetermined size integrally, so that the user can grasp the handle directly to another person without the help of others It is easy to move, as well as a pair of vertical connecting rods fixed to the board The purpose of the present invention is to provide an easy-to-move board that can be used by arbitrarily adjusting the height of the board to the height of the user.
