Claims

[Scope of utility model registration request]

provided on the underside of the article having wheels for movement;
A fixing device that fixes the article by raising the wheels above the floor surface, etc., which includes a main body frame to which leg members are attached, and the article is supported so as to be movable up and down relative to the frame. a mounting member fixed to a lower surface; a pedal whose base is fixed to a drive shaft supported by the frame and rotates the drive shaft when the pedal is depressed; and the mounting member when the drive shaft is rotated in the direction in which the pedal is depressed. a link mechanism that moves the drive shaft relatively upward; a lock mechanism that prevents the drive shaft from rotating in the pedal return direction when the pedal is depressed at an intermediate position; and a return spring that rotates the drive shaft in the pedal return direction to the initial position when the lock is released by the mechanism, and the lock mechanism rotates integrally with the drive shaft. and a locking cam having a stepped portion at a predetermined position on its circumferential surface, and an engaging pawl that engages with the stepped portion of the cam at an intermediate rotating position of the drive shaft corresponding to an intermediate depressed position of the pedal. and an elastic member in which the lock release mechanism elastically holds the engagement pawl in the disengagement position when the drive shaft is rotated beyond the intermediate rotation position in the pedal depression direction; A return cam that returns the engagement pawl from the disengaged position to the initial position against the elastic force of the elastic member after the drive shaft passes the intermediate rotation position when the drive shaft rotates in the pedal return direction. A fixing device for a wheeled article, characterized in that:
