Patents by Inventor Yuuichi Hatano

Yuuichi Hatano has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11008789
    Abstract: A biaxial hinge which can be downsized. The biaxial hinge includes a first main body, an intermediate body coupled to the first main body so that the intermediate body can rotate around a first shaft and a second main body coupled to the intermediate body so that the second main body can rotate around a second shaft which is parallel with the first shaft. Two laminated first friction plates are engaged with the first shaft. Two laminated second friction plates are engaged with the second shaft. The first main body supports the first shaft so that the first shaft cannot rotate. The second main body supports the second shaft so that the second shaft cannot rotate. The first friction plates and the second friction plates are contained in the intermediate body so that the first friction plates and the second friction plates cannot rotate.

  • Patent number: 10151128
    Abstract: Provided is a torque hinge which can be easily assembled. A torque hinge includes a restricting member 3 having a hole 31, a shaft 4 passed through the hole 31 of the restricting member 3, a friction member 6 engaged with the shaft 4 in an interference fitting state so as to generate torque due to friction to the shaft 4 which relatively rotates and fitted in the hole 31 of the restricting member 6, and a fixing shaft 41 for unrotatably fixing the friction member 6 to the restricting member 3, the fixing shaft 41 intervening between the friction member 6 and the restricting member 3. The fixing shaft 41 presses a wedge-shaped rotation locking portion 44 of the friction member 6 onto an inner surface of the hole 31 of the restricting member 3.

  • Patent number: 8732908
    Abstract: There is provided a hinge with torque setting function for connecting two objects by a hinge shaft adapted to be assembled with precision and to be tightened easily. In order to reduce the diameter of the curvature portion 42 of the holder 40 through the brake member 30 on the hinge shaft 20, there is attached by the screw the adjusting member 46 which can vertically move within the latch portions (vertical grooves) 42G of the curvature portion 42 individually from an angular movement of the curvature portion 42 when it is tightened. The screw 5 can be tightened by vertical movement thereof without being restrained by the angular movement of the curvature portion 42 and therefore, the tightening of the holder 40 can be carried out with high precision and effectiveness of operation.
