From the background information supplied by the inventors, news correspondents obtained the following quote: "Flip electronic devices, such as notebook computer, mobile phone or the like, usually have a screen connected with a keyboard via a hinge to provide a required torsional force when the screen is unfolded against the keyboard. The common flip electronic device often has a hinge pivotally coupled with a base and an upper lid thereof to make them foldable and unfoldable. For instance, R.O.C. patent No. M388822 discloses a turnable double-pin hinge with a first pin fastened to a screen bracket and a second pin fastened to a base bracket. The first pin can be swiveled about the second pin to change the position of the first pin upwards or rearwards, thereby drive the screen bracket upwards or rearwards to prevent interference between the screen housing and base housing during unfolding. It also has a track panel and a control member to harness movements so that the screen bracket can be swiveled at an angle equal to the sum of the swivel angles of the first pin and second pin. Namely the swivel angle of the screen is formed by combining the turning angles of the first pin and second pin. However, the aforesaid flip electronic device has to swivel the screen and base at an included angle greater than 90 degrees to provide a comfortable visual angle for users to see the information displayed on the display device such as the screen.
"In order to save use space, R.O.C. patent No. M413776 discloses a band type double-pin hinge. It includes a pin sleeve and a first swivel member and a second swivel member located in the pin sleeve. The pin sleeve has a coupling plate and a first coupling portion and a second coupling portion located on the coupling plate. The first coupling portion and second coupling portion have respectively a first pin passage and a second pin passage to hold respectively the first swivel member and second swivel member. The first coupling portion has an edge at one side of the coupling pate formed a first notch communicating with the first pin passage, and the second coupling portion has another edge at another side of the coupling plate formed a second notch communicating with the second pin passage. The double-pin hinge thus formed can be swiveled sequentially at a greater angle, and also can be unfolded lightly and folded at a greater force. It also allows the upper lid to be flipped 360 degrees to fold over the base. Although it saves use space, the entire electronic device has to be taken up to flip the upper lid for 360 degrees, then be rested on a flat surface. It still leaves a lot to be desired in terms of usability.
"From user's perspective, usability can be greatly enhanced if the hinge is constructed to enable the screen to be flipped directly from the tabletop not greater than 90 degrees without holding the entire electronic device while the screen can be seen by users at the front side."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "The primary object of the present invention is to solve the problem of the hinge structure in the conventional electronic devices that requires a greater use space and users should hold the entire device to adjust the screen to a suitable viewing position both of that result in poor usability.
"To achieve the foregoing object, the invention provides a movable hinge to pivotally couple with a base and a back panel of an electronic device. The back panel has a support portion and a housing compartment located in the support portion. The movable hinge includes a first slide portion and a second slide portion slidable against the first slide portion. The first slide portion is held in the housing compartment, and includes a track portion and a first sloped surface connected to the track portion. The second slide portion has a first pin with two ends respectively running through the track portion and fastening to the base, a butting portion coupled on the first pin and slidable thereon, and an elastic element coupled on the first pin and interposed between the butting potion and the base. The first pin is located at the bottom end of the track portion. The back panel is formed at a first position. The butting portion compresses the elastic element to generate a return force thereof so that the butting portion is pushed by the return force of the elastic element to move along the first sloped surface to press the first slide portion to slide against the second slide portion and drive the back panel to move against the base.
"In one aspect the electronic device includes a display device and a hinge portion to pivotally couple the display device and the back panel.
"In another aspect the hinge portion includes a second pin hinged on the display device and a fastening portion fastened to the back panel.
"In yet another aspect the elastic element is a spring.
"In yet another aspect the butting portion has a second sloped surface corresponding to the first sloped surface.
"The invention thus formed provides many advantages, notably:
"With the butting portion pushed by the elastic element, the second sloped surface of the butting portion presses the first sloped surface of the first slide portion so that the first slide portion is butted by the butting portion and slid against the second slide portion to drive the back panel to move against the base. Incorporating with the hinge portion, the display device can be unfolded directly from the tabletop and flipped for 180 degrees for folding without lifting more than 90 degrees, so that information displayed on the display device can be seen by users clearly. Usability improves and use space also can be saved.
"The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings."
