Publication number: 20100137041Abstract: Disclosed is a pivot apparatus having a pivot member adapted so that, when pivoted to the service angle, it slides to the service position while interlocking with the pivot movement and is set in the service condition. To this end, a link interlocks the pivot movement based on the pivot structure with the sliding movement based on the siding structure. Particularly, the sliding structure is applied to the coupling between the support and sliding members, and the pivot structure is applied to the sliding and pivot members to pivotably couple them to each other. The link connects the support and sliding members so that, as the pivot member pivots relative to the sliding member by means of the user's pivot force, the sliding member slides to the desired direction and distance from the support member while interlocking with the pivot movement. As a result, the pivot member slides while interlocking with the pivot movement.Type: ApplicationFiled: May 7, 2008Publication date: June 3, 2010Inventor: Han Sang Lee

Publication number: 20100134973Abstract: A bendable apparatus, which is able to change its state between a straightened state and a bent state using an external force, is disclosed. This bendable apparatus includes a top bracket and a bottom bracket which is rotatably axle-joined with the top bracket. Also, the bendable apparatus includes a swing link, which is rotatably axle-joined to the top bracket, concurrently engages with a portion of the bottom bracket, and makes the bottom bracket rotate itself about the top bracket by an external force applied to a swing link protrusion and by a predetermined angle about an axle with which the bottom bracket is joined with the top bracket. When the external force is applied to an opposite direction, the bendable apparatus goes back to the straightened state. If this bendable apparatus is applied to a mobile phone of a sliding opening type, a portion with a microphone can be bent by a predetermined angle when the mobile phone is opened.Type: ApplicationFiled: May 7, 2008Publication date: June 3, 2010Inventor: Han Sang Lee

Patent number: 7542788Abstract: Disclosed is a sliding mechanism apparatus used for slidably opening and closing a slider-type cellular phone. A guide member and a slider member are engaged with each other so as to enable to slide relative to each other. The end of one arm of a first torsion spring is connected to the slider member near the left edge thereof. The end of the other arm thereof is coupled to the right half area of the guide member. The end of one arm of a second torsion spring is connected to the slider member near the right edge thereof. The end of the other arm thereof is coupled to the left half area of the guide member. From the expanded original state of the first and second torsion springs, if an external force is exerted on the slider member or the guide member, the torsion springs are compressed into an acute angle and then spread again by means of the elastic force thereof. In this way, the slider member can move to the lowermost position or the lowermost position.Type: GrantFiled: February 11, 2005Date of Patent: June 2, 2009Assignees: P & Tel Inc.Inventor: Han Sang Lee
