JPS6432808A - Desk having notched upper plate and bottom plate - Google Patents

Abstract

PURPOSE: To provide a desk which normally allows doing office work and if necessary making calculations and records using a computer or the like by causing a notched top panel to be stored in a back storage part by the normal rotation of a motor, and at the same time raising a bottom panel to fit it into a notched hole. CONSTITUTION: When a rotor 3-a mounted on a power shaft 9 rotated back and forth by a motor 8 with a reduction gear is rotated in the normal direction during a rise, a notched top panel 6 gradually descends perpendicularly to the back storage part 12 of a desk while describing with its end a circle about the shaft 2 of a rotor 3-b without being forced down to the back by a support arm 11 connecting a support arm rail 10 to the notched top panel 6. At the same time, a bottom panel 7 rises stably since a guide roller 13 mounted at one end thereof works to hold horizontality along a guide rail 14 provided on each side of the inner surface of the desk, and the bottom panel 7 is fitted into a notched hole 5 in a desk pain panel 4, is stopped in a horizontal position, and integrated with the desk main panel 4. At the same time, the notched top panel 6 is also stopped in a vertical position in the back storage part 12. The use of the desk in office work with a computer or the like enables space savings.
