Title:
ELECTRIC ASSISTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/072729
Kind Code:
A1
Abstract:
An electric assisting device for varying the moving speed of a movable object in
response to the demand of the user. When a cabinet of an electric suspended closet
(10) is moved, a microcomputer (82) derives a target rotational speed from the
level of the voltage outputted from a strain sensor (72) provided to a handle part
and rotates the rotary shaft of a motor (40) at the target rotational speed by feedback
control. In consequence, the arm of the electric suspended closet (10) is rotated
to rotate the cabinet. Thus, the lowering or raising of the cabinet by the user
is assisted. That is to say, if the load needed to move the cabinet is heavy (the
load of the cabinet is heavy or the cabinet is fast moved), the speed of the movement
of the cabinet is high, and the assisting force by the motor (40) is strong. Therefore,
in response to the demand of the user, the moving speed of the cabinet can be varied.
