  • Publication number: 20130091774
    Abstract: An opening and closing device includes a cover gear, a driving source, a cover, a biasing element, and a control portion. The cover gear is rotatably supported in both forward and backward directions. The driving source selectively provides rotation to the cover gear in both the forward and backward directions. The cover is rotatably supported to allow motion in both the forward and backward directions between first and second positions. The biasing element transmits the rotation of the cover gear to the cover while biasing the cover in a predetermined direction from the first position to the second position. The control portion stops the rotation of the driving source, in a case in which the driving source is rotated to move the cover in the predetermined direction, when the cover gear rotates in the predetermined direction by a predetermined angle after the cover has reached the second position.

  • Patent number: 6925684
    Abstract: A hinge device of an information terminal, wherein the information terminal comprises a main body, a sub-body to be opened away from or closed to the main body while rotating about a hinge axis extending in one direction of the main body, and the hinge device for rotatably coupling the main body to the sub body. The hinge device comprises a driving part generating a driving force for rotating the sub body, and a clutch part for rotating the sub-body by the driving force of the driving part. When the sub-body rotates by external force, the clutch part prevents rotating force of the sub-body from being transmitted to the driving part. Such a hinge device configured as stated above allows the user to automatically open and close the sub-body of the information terminal by virtue of a driving motor provided therein, as well as to manually open and close it. Further, the user can freely adjust an opening angle of the sub-body to various angles, resulting in improvement in convenience of use.

  • Patent number: 6694674
    Abstract: The present invention relates to a door opening/closing device installed in a door of a building to be opened/closed about a hinge fixed at one side of the door. The opening/closing device controls the door to be manually opened and closed with an automatic returning device. When the door is opened by a rotating power adjusting device of the door, an oil pusher-plate in a rotary member pushes oil in an oil reservoir so that rotation speed of oil is adjusted by the pressure of oil passing through an oil passage hole, the end of the oil pusher plate and the inside wall of the oil reservoir. The door is opened in a joggling manner but slowly closed as rotating speed of the door gradually decreases, thereby solving problems such as injury occurring at the time of closing the door. A door fixing unit securely fixes the door when the door is closed or opened so as to prevent a gap between the door and a door frame when the door is closed and securely fix the door without movement when the door is opened.

The axial operator comprises a rotatable operator output member that rotates about an operator axis, the operator output member being constructed and arranged to be operatively connected within the door assembly such that the operator output axis extends generally vertically. An electric motor has a rotatable motor output member that rotates about the operator axis. The motor is constructed and arranged to selectively rotate the motor output member about the operator axis. A reduction transmission is connected between the motor output member and the operator output member. The reduction transmission is constructed and arranged such that the transmission rotates the operator output member at a lower rotational speed than a rotational speed at which the motor rotates the motor output member and applies a higher torque to the operator output member than a torque which the motor applies to the motor output member.

    Abstract: A bulk material container with an opening has a door arranged to move over a rectilinear path for the opening and the closing of the opening. For moving the door over a rectilinear path to either open or close the opening, a threaded shaft is journalled for rotation within the container and is aligned axially with the center of the door. Means on the threaded shaft engage the door so that the door is moved over the rectilinear path by the rotation of the threaded shaft. A gasket surrounds the opening at the time of closure of the door. Continued rotation of the shaft for the closure of the door will cause the gasket to be compressed against the plate surrounding the opening. Rotation of the door is inhibited while the gasket is being compressed.
