Patent number: 6491248Abstract: A measuring tape has a check device for automatically preventing a ruler from rewinding. The check device is installed within the casing and positioned between a winding wheel and a ruler body. The check device comprises a rotary wheel formed by an elastic wheel and two ratchets; a guide block having stop blocks; a stop claw; a driven element installed between the press button and the stop claw; and a press. By above components, the ruler body can be installed between the elastic wheel and the guide block. As the ruler body is pulled out, it can be stopped automatically. Only after pressing the press button, the ruler body rewinds. Thereby, the user may operate it by only one hand not to worry about that the hand will be hurt due to the rewinding of the ruler body.Type: GrantFiled: August 21, 2001Date of Patent: December 10, 2002Inventor: Simon Liu

Patent number: 6416009Abstract: A retractable hose reel assembly comprises a reel (2) rotatably mounted in a casing (1) and a torsion spring (8) for rotating the reel in a direction corresponding to winding of the hose on the reel (2). A ratchet (14) and pawl (18) prevent or limit rotational movement of the reel (2) in the winding direction. A lever (20) is manually movable to a locking position in which unwinding movement of the reel (2) is prevented, for example to prevent vandalism or to prevent a child pulling the hose from the reel and suffering discomfort or injury as a result of retraction of the hose by the spring (8).Type: GrantFiled: June 28, 1999Date of Patent: July 9, 2002Assignee: Hozelock LimitedInventors: Nicolino Iaciofano, Michael Lars George Hill
