Coil Patents (Class 267/166)
  • Patent number: 11131356
    Abstract: In the coil spring of the present invention, a helical space defined by a space between coils has a first end region whose space is increased as it extends towards the other side in the axial direction from a first reference point where the space is zero, a reference region whose space is set at a reference value L (L>0), and a second end region whose space becomes narrow as it extends toward the other side in the axial direction and zero at a second reference point. The first end region has a first end outer part and a first end inner end. In a case where a pitch angle of the space between coils that causes the displacement of the space between coils per turn of the helical space to be L is a reference pitch angle Pa, the pitch angle in the first end outer part is set at Pa while the pitch angle in the first end inner part is set at Pb (Pb>Pa).

  • Patent number: 11000448
    Abstract: A Handheld Motorized Facial Brush Having Specialized Torque Transfer Clip. The heads interface with a conventional handpiece so that the facial brush or other facial treatment head can be removed and replaced with a head chosen from a group of treatment heads. The handpiece has a sealed, washable head portion that can be activated to rotate. Each treatment head or treatment assembly includes a torque transfer clip that provides biasing force between the handpiece and the head, but at the same time results in additional vibration being transferred from the vibration generator in the handpiece to the treatment head. The torque transfer clip also allows for some flex between the treatment head and the handpiece.

  • Patent number: 8857801
    Abstract: A composite coil spring includes a coil body that extends along a coiled axis. The coil body includes a core and a plurality of fiber layers impregnated with a polymer material. The plurality of fiber layers are arranged around the core at different radial distances from the coiled axis. Each of the plurality of fiber layers extends around the coiled axis at an oblique fiber angle to the coiled axis. Each of the plurality of fiber layers includes a number of fibers that is a product of a common base number of fibers multiplied by a positive non-zero integer from a set of positive non-zero integers. The positive non-zero integer of at least one of the plurality of fiber layers is different from the positive non-zero integer of at least one other of the plurality of fiber layers.
