摘要： A 3D printed additively manufactured (AM) elliptical bifurcating torsion flexure assembly system includes a base section; elliptical bifurcating torsion springs, each including a bifurcated legs section supported by the base; a bifurcated elliptical torsion spring section contiguous with the bifurcated legs section; and a single upper section contiguous with the elliptical torsion spring section. The single upper section includes a connection component, and the device material includes Hot Isostatic Pressing (HIP) heat-treated Ti6Al4V. The elliptical bifurcating torsion flexure assembly is printed as one part by a 3D additive manufacturing process, and the bifurcation maintains consistent balance while being torqued. The stiffness-spring rate of the device is at least partly controlled by varying cross-sectional shape and diameters by the 3D additive manufacturing printing.

摘要： A spring body configured with a plural of spring segments formed along a longitudinal axis of the spring body. The spring segments form an opening along one side that is configured to accept one or more optical fibers, and secure the fiber bundle from being dislodged from a bore formed by the spring segments.

摘要： A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.

摘要： A connector includes a first buffer member that includes a spiral-shaped wire, a second buffer member that has a substantially annular and flat plate-like shape capable of warping in a thickness direction, a collar member that includes a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member, and a coupling member. A gap for allowing the second buffer member to move in a radial direction is formed between the second buffer member and a cylindrical portion. A distance between a position of a surface of the second flange and a position of a lowest end of the collar member is greater than a distance between a position of a surface of the first flange and the position of the surface of the second flange in a view in an axial direction.

摘要： A side-load, hung window assembly can include a sash guide attached to the window sash and extending into a space between the window sash and the jamb channel. The sash guide can include a recess at an outer end to provide clearance for the sash guide to pass over the uncurled end portion of the curl spring and the mounting device. In addition, an aesthetic cover can be disposed over the mounting device. Alternatively or in addition, a spring cover can be disposed over the uncurled end portion of the curl spring and the mounting device.
