Patent number: 8916242Abstract: A connector system facilitates the connection of a first tree trunk to a second tree trunk of an artificial tree system, and further protects one or more ends of a trunk when, for example, the artificial tree system is being shipped or stored. The connector system comprises a sleeve. The sleeve comprises a cylindrical shaped body. The outer of the body has a uniform cylindrical shape. The interior of the sleeve has different diameters at its top and bottom. The interior includes a notch or shoulder. The shoulder is in proximity to the top end of the sleeve. The sleeve further comprises a cutout for assisting with connecting and securing the trunks together.Type: GrantFiled: December 30, 2010Date of Patent: December 23, 2014Assignee: Polygroup Macau Limited (BVI)Inventors: Yong Fu, Chung-Wai (Paul) Cheng

Patent number: 8753135Abstract: A lamp system used in a light string system comprises a light assembly and a socket assembly. The light assembly comprises a light source, a base in communication with the light source, and a bypass activating system. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The bypass mechanism is in the first position when the light assembly is not seated in the socket assembly. When the bypass mechanism in the first position, current flows across the bypass mechanism. When the light assembly is inserted into the socket assembly, the bypass activating system of the light assembly moves the bypass mechanism into the second position, and current flows through the light source instead of the bypass mechanism.Type: GrantFiled: March 13, 2013Date of Patent: June 17, 2014Assignee: Polygroup Macau Limited (BVI)Inventors: Chung-Wai (Paul) Cheng, Yong Fu, Chi-Yin (Alan) Leung, Hou-You Han
