  • Patent number: 9441714
    Abstract: A jacking device is provided to push an object for rotation and upward or downward movement. The jacking device includes a combination of a slave arm and a link arm. The slave arm includes a first end capable of producing rotation and linear movement and a second end pivoted to the link arm. The link arm includes a fixation end disposed on a base and a free end. When the first end of the slave arm is received with an action force, the second end of the slave arm is forced to push the link arm for rotation, and the free end of the link arm is forced to motion between a first position and a second position so as to push an object for rotation and upward or downward movement.

  • Patent number: 8982572
    Abstract: The invention relates to a control device for executing an open mode of a motion module of an electric apparatus. The electric apparatus includes a motion module and a machine body module. The control device disposed on a path of the relative movement includes a combination of a carrier and an elastomer, in which the carrier has a blocking portion. The elastomer normally keeps the carrier at a first position, and the elastomer allows the carrier to motion toward a second position when the carrier is pressed. The control device allows the motion module to rotate (in an open mode) when the motion module crosses the blocking portion of the carrier. Accordingly, the invention promotes visual artistic effects by eliminating the essential exposure of the rotary shaft in the rotation-open mode of conventional skills.

  • Patent number: 8964381
    Abstract: An electronic device locking/unlocking mechanism assembled with an electronic device. The locking/unlocking mechanism includes a connection arm movable between a first position and a second position. The connection arm has a first end and a second end. An elastic unit is disposed at the first end of the connection arm to normally apply an elastic force to the connection arm for keeping the connection arm positioned in the first position. A locking section is disposed at the second end of the connection arm. The locking section is held in a dent formed on the electronic device. When the connection arm is moved to the second position, the locking section is released from the held state, whereby a pivot pin is unstressed to automatically bound open the electronic device.

  • Patent number: 8831696
    Abstract: A slide-aid device for electronic apparatus includes a linkage mechanism and an elastic unit assembled with the linkage mechanism. The linkage mechanism has a first arm and a second arm pivotally connected with the first arm. The elastic unit has a fixed end and a connection end. The connection end is pivotally connected with the second arm, whereby the elastic unit is movable with the second arm. When an operation force is applied to the first arm, the first arm is moved to drive the second arm so as to make the elastic unit store energy. After the first arm passes over a reference axis, the elastic unit releases the energy to provide an action force to help the operation force.

  • Patent number: 8740459
    Abstract: A relative displacement device with both slight push force and strong elastic pull force includes two displacement members displaceable relative to each other. The displacement members are respectively formed with two turning displacement paths, which turn from a relative displacement direction in different directions. During displacement travel of the displacement members, the turning displacement paths intersect each other at different points as elastic pull points. Each turning displacement path has two path terminals and a turning point. The displacement reference line of the path terminals of one turning displacement path coincides with the displacement reference line of the turning point of the other turning displacement path. A first end of an elastic member is slidably pivotally positioned at the elastic pull point as an elastic pull end, while a second end of the elastic member is pivotally fixed at a fixed point of one displacement member as a fixed end.

  • Publication number: 20140021727
    Abstract: An opening-aid locking/unlocking mechanism of electronic device, which is assembled with the electronic device. The electronic device includes a movable module and a device body module. The opening-aid locking/unlocking mechanism is disposed between the movable module and the device body module. The opening-aid locking/unlocking mechanism includes an elastic section. When the movable module is closed and locked with the device body module, the elastic section stores energy. When the movable module is unlocked, the elastic section releases energy to push open the movable module or the device body module so as to eliminate the problem existing in the conventional mechanism that the electronic device is uneasy to open and the pressure exerted on a user's hand is increased.
