Title: Supporting device for revolving board
Inventor: UEDA RYUICHI
IPC: A47B97/04
Filed: 1988-07-22
Abstract: PURPOSE:To make it possible that a revolving board used reversibly for a blackboard, etc., is simply turned over without trouble in the state of fixing a base body on a wall, etc., by providing a supporting mechanism which supports a revolving board possible to turn over around a shaft on a vertical plane. CONSTITUTION:After a shaft 11 of a locking device 10 is turned, a locking member 13 is removed from a locking pin 23C; and when a No.3 link 23 is shifted around a pin by a handle for a blackboard 7, the blackboard 7 is pushed forward according as the lower end part (pin 8a) is horizontally shifted. IN this case, since most of vertical load based on a dead weight of the blackboard 7 is transmitted to a compressing force of the No.3 link 23, a hinging motion of the No.3 link 23 or a horizontal shift of the blackboard 7 is smoothly done by a little external force. When the blackboard 7 is pushed toward the base body 1 and relocked after being turned on the pin 8a at an angle of 180 deg., it is possible that the reversed side of the blackboard 7 is used. It is therefore possible that both sides of the blackboard 7 are used in the state that the base body is directly fitted with a wall W without largely keeping all the unit from the wall W.
