And Barrels For Helical Springs On Separate Axes Patents (Class 16/283)
  • Patent number: 12057093
    Abstract: A hinge assembly having reinforced abutment surfaces for use in a neck of a foldable fretted instrument. Multiple strike plates are mounted to the hinge assembly, which are made from stronger and more robust materials than the underlying hinge such that the strike plates bear the loads (vs. the underlying hinge material) to prevent deformation of the hinge components during use over time. An elongated locking strut is dimensioned to be slidably advanced into the hinge assembly to selectively lock and unlock the neck of the foldable fretted instrument.

  • Patent number: 10365694
    Abstract: A pivot structure assembly including a fixed cover and a hinge module is provided. The hinge module includes a torque element, a first shaft, a second shaft, a first bracket and a second bracket. The torque element is fixed on the fixed cover and has a first and a second axle sleeves, parallely disposed at two opposite sides of the torque element. The first shaft is disposed through the first axle sleeve, and the second shaft is disposed through the second axle sleeve. The first bracket is pivotally disposed on the torque element through the first shaft, and the second bracket pivotally disposed on the torque element through the second shaft. When the first and second brackets rotate relatively to the torque element, the first and second axle sleeves respectively provide different friction forces to the first and second shafts. In addition, an electronic device is also mentioned.

  • Patent number: 7533444
    Abstract: A hinge mechanism (20) includes a mounting member (12), at least one retractable elastic shaft (14) and a rotating member (18). The retractable elastic shaft has two opposite ends. The mounting member is located at one end of the retractable elastic shaft and defines at least one first hollow (125). The rotating member is located at the other end of the retractable elastic shaft and defines at least one second hollow (187). The first and second hollows respectively receive two ends of the retractable elastic shaft. The mounting member is rotatable relative to the rotating member to drive the retractable elastic shaft to move between a first position where the retractable elastic shaft is slantwise to an axis of the rotating member and a second position where the retractable elastic shaft is parallel to the axis of the rotating member. The hinge mechanism is easy to be manufactured.

  • Publication number: 20080115322
    Abstract: A parallelogram hinge for vertical-movement doors comprises a first plate designed to be fastened to the furniture flank, a second plate designed to be fastened to the door and two superposed arms pivotally mounted to the plates to form an articulated parallelogram. A spring for movement balancing is connected to the upper arm at an intermediate position between the arm extremities hinged to the plates and is connected to the first plate at a point below the pivot point of the lower arm on the first plate. This enables very reduced bulkiness in the direction of the furniture depth, achievement of a great opening angle and better operation of the spring embodied by a gas piston.

  • Patent number: 5606774
    Abstract: A double tubed door hinge for automatically closing a door comprises a two-tube base, a pair of torsion springs disposed to respective tubes therein and urged at two ends by a pair of first twisting members and a pair of second twisting members, and retained by a pair of lug members and a pair of axle rods. The improvement has been characterized in that an annular sleeve is placed between the first twisting member and the upper rim of the tube and a splitting small tube disposed into the first and second twisting members. In addition to that both the twisting members and the annular sleeve are made from reinforced plastic material and the splitting small tube is made from anti-friction material. So that the door hinge is durable and provides a smooth operation without causing any noise.
