Patent number: 8469380Abstract: An extending and retracting device for a vehicle-step apparatus includes a mounting bracket and step bracket. A first arm defines a first end pivotally connected to the mounting bracket and a second end pivotally connected to the step bracket. A second arm defines a first end pivotally connected to the mounting bracket and a second end. A third arm defines a first end pivotally connected to the second end of the second arm and a second end pivotally connected to the step bracket. A trajectory-control assembly is configured to connect the first arm to the second arm and/or third arm to control a “motion” trajectory of the step bracket. A vehicle-step apparatus includes a step member, the extending and retracting device, and a driving device driving the first arm and/or second arm to move the extending and retracting device between an extended position and a retracted position.Type: GrantFiled: January 5, 2011Date of Patent: June 25, 2013Assignee: T-Max (Hang Zhou) Industrial Co., Ltd.Inventors: Huizhong Yang, Zhaobo Qing

Patent number: 8267379Abstract: A cable guiding device includes a base, upper and lower guide members disposed along a longitudinal direction, in which two ends of the upper guide member are mounted on the base and two ends of the lower guide member are mounted on the base. A slider defining a central cavity is penetrated therethrough in a lateral direction substantially perpendicular to the longitudinal direction. Upper and lower movable members are fitted slidably over the upper and lower guide members respectively, in which two ends of the upper movable member are mounted on two longitudinal side walls of the slider, and two ends of the lower movable member are mounted on two longitudinal side walls of the slider respectively. Upper and lower guiding rollers are fitted rotatably over the upper and lower movable members and disposed within the central cavity respectively.Type: GrantFiled: July 7, 2010Date of Patent: September 18, 2012Assignee: T-MAX (Hang Zhou) Industrial Co., Ltd.Inventors: Huizhong Yang, Zhaobo Qing, Wei Bao

Patent number: 7806386Abstract: A braking device for a winch comprises a braking bush, a brake driving shaft having one end connected to an output shaft of the motor and another end of the brake driving shaft having a first axial protrusion. A brake driven shaft defines an end rotatably disposed in the braking bush and having a second axial protrusion opposed to the first axial protrusion. A brake shoe is disposed between the first axial protrusion and the second axial protrusion. An elastic member is connected to the second axial protrusion and the brake shoe and normally urges the brake shoe toward the first axial protrusion. A winch having the braking device is also disclosed.Type: GrantFiled: December 29, 2008Date of Patent: October 5, 2010Assignee: T-Max (Hang Zhou) Industrial Co., Ltd.Inventors: Huizhong Yang, Zhaobo Qing
