Patent number: 8180416Abstract: A sliding-type mobile communication terminal having a first housing and a second housing opened or closed by means of a sliding movement in a longitudinal direction of the first housing, The terminal includes a spring module adapted to provide a sliding force, along the longitudinal direction, for closing of the second housing within a predetermined range of distance, and for providing the sliding force in an opposite direction for opening of the second housing beyond the predetermined range of distance. The spring module includes link bars rotatably coupled in one end onto the first housing, coil springs supported by one end of the link bar and coupled to enclose the link bar, and a slider slidably coupled to the link bar to be acted upon by an elastic force from the coil spring. The coil springs implement a semi-automatic sliding opening/closure of the second housing.Type: GrantFiled: March 5, 2008Date of Patent: May 15, 2012Assignee: Samsung Electronics Co., LtdInventors: Tae-Keon Park, Chul-Ho Bae, Tae-Ha Chang, Su-Yong Jung

Patent number: 6963766Abstract: There is provided a hinge module for mechanically connecting a main body to a folder in a portable radio terminal. In the hinge module, a hinge shaft has an angled portion on one end and a shaft on the other end thereof, for rotating with the folder. A hinge cam is disposed to face the hinge shaft and has a pair of angled portions on the surface facing the hinge shaft, a valley portion between the angled portions, a fixing post along a rotating axis, and a guide protrusion for facilitating sliding of the hinge cam with respect to the hinge shaft while restricting rotational movement of the hinge cam. Each angled portion has a gentle slope and a steep slope that are asymmetrical sidewise. A hinge spring is disposed along the rotating axis and has one end connected to the fixing protrusion of the hinge cam, for providing restoring force to the hinge cam.Type: GrantFiled: December 20, 2001Date of Patent: November 8, 2005Assignee: Samsung Electronics Co., Ltd.Inventor: Su-Yong Jung
