Description

【考案の詳細な説明】本考案は、縦方向にも横方向にも転位して使用
することのできる黒板に関する。[Detailed Description of the Invention] The present invention relates to a blackboard that can be used by being transposed both vertically and horizontally.

特に本考案の黒板は、実用新案登録第1128625
号（実公昭50−31068号）を以て、本件出願人が
先きに提案した拭消装置付黒板を改良したもの
で、拭消装置の機構は一切図示を省略してあり、
黒板を横長方向に使用する従来普通の使用から、
必要に応じてそのまま縦長方向に転位して使用で
きるようにしたものである。 In particular, the blackboard of this invention has a utility model registration number of 1128625.
No. (Utility Model Publication No. 50-31068), this is an improved version of the blackboard with a wiping device that the applicant had previously proposed, and the mechanism of the wiping device is not shown at all.
From the conventional use of blackboards in landscape orientation,
It is designed so that it can be used as it is by being transposed in the longitudinal direction as needed.

本考案の構成を図面について説明すると、黒板
主体１の裏面に一定の間隔をもつように取付けた
転子２を、前記黒板主対１の裏面に対向する支台

ことにより回転自在に接続してなり、前記転子２
は図示では四個をほぼ等間隔にして示したが、三
個もしくは四個以上として軌条環３の内縁に嵌合
しても同作用の回転が可能である。 To explain the configuration of the present invention with reference to the drawings, the trochanter 2 is attached to the back surface of the blackboard main body 1 at a constant interval, and the rail ring is attached to the surface of the support base 4 facing the back surface of the blackboard main pair 1. The trochanter 2 is rotatably connected by fitting from the inside of the trochanter 2.
In the illustration, four pieces are shown spaced at approximately equal intervals, but even if three or more pieces are fitted to the inner edge of the rail ring 3, the same rotation effect is possible.

然して、前記転子２の取付位置の中心を黒板主
体１の中心より僅かに一方に扁心させるか、或は
横長方向にした場合の黒板主体１の中央下部に重
量物５を有せしめることで、黒板主体１を縦長方

８が黒板主体１の縦長方向位置を保つ掛止を行
い、その掛止を解放すると、黒板主体１は重量の
偏りで横長方向に変位することになる。 However, by making the center of the mounting position of the trochanter 2 slightly offset to one side from the center of the blackboard main body 1, or by having a heavy object 5 at the lower center of the blackboard main body 1 when it is oriented in the horizontal direction, , the blackboard main body 1 is constantly biased from the vertical direction to the horizontal direction, and a stopper 8 attached to a part of the back surface of the blackboard main body 1 engages the blackboard main body 1 to maintain its vertical position. When the latch is released, the blackboard main body 1 is displaced in the horizontal direction due to the uneven weight.

黒板主体１の側面の重量物５は、先きに提案し
た拭消装置のモータ又は伝導歯車によつて自ら重
量偏位の作用を具有するものである。 The heavy object 5 on the side of the blackboard main body 1 has a weight shifting function by itself by the motor or transmission gear of the wiping device proposed earlier.

本案の構成は以上のように、黒板を縦長又は横

長方向に変位するとき、転子２が軌条環３を回転

向への移動を制止し、またその制止を開放すると
黒板は横長方向に変位し、重量配分の安定した横
長の位置で移動を停止するに至る。 As described above, the configuration of the present invention is implemented on a transposed blackboard in which the blackboard is used vertically or horizontally, and when the blackboard, which is usually horizontally oriented, is displaced vertically as necessary, the trochanter 2 moves smoothly while rotating the rail ring 3, and the blackboard is supported in the vertical direction at a position where the claws of the stopper 8 attached to a part of the vertical frame of the blackboard main body 1 are hooked to the vertical frame of the support base 4. When the blackboard is restrained from moving in the horizontal direction, and the restraint is released, the blackboard is displaced in the horizontal direction, and the movement is stopped at a horizontal position where the weight distribution is stable.

上記の如く、本案黒板は、普通の横長方向から
縦長方向と、任意に変位して使用できるので、黒
板の表記が便利であり、その構造も堅牢で判り易
く実施容易である等の実用的効果がある。 As mentioned above, the proposed blackboard can be used in any direction from the normal horizontal direction to the vertical direction, so the notation on the blackboard is convenient, and its structure is robust, easy to understand, and has practical effects such as being easy to implement. There is.

Claims

[Scope of utility model registration request]

The trochanter 2 attached to the back of the blackboard main body 1 is attached to the support 4
A heavy object 5 is attached to the lower center of the side surface in the horizontal direction of the blackboard main body 1, and is attached to the back surface of the blackboard main body 1. This vertically and horizontally disposed blackboard stabilizes the vertical position of a blackboard main body 1 by engaging the claws of a stopper 8 with the vertical frame of a support 4.
