摘要: A coil spring includes a wire rod and an elastic coat provided on the wire rod. The coil spring includes a coil section including a plurality of coil portions. The wire rod includes a round cross-sectional portion, a cross-section varying portion, and a rectangular cross-sectional portion along the longitudinal direction of the wire rod. The cross section of the rectangular cross-sectional portion is substantially square and has a first plane and a second plane. The first plane and the second plane oppose each other in the coil section. The elastic coat is provided on at least one of the first plane and the second plane. The elastic coat is continuous from the round cross-sectional portion to the cross-sectional variation portion and the rectangular cross-sectional portion.

摘要: 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 is configured such that the number of turns of the helical space is greater than 1 and the space between coils in a terminal position is greater than the reference value L. The helical space has a first transitional region between the terminal position of the first end region and the reference region, the first transitional region being configured so that the distance of space between coils is reduced from the terminal position of the first end region along the helical shape of the helical space toward the other side in the axial direction and becomes the reference value L.

摘要: A device for reducing impact forces upon a surface includes a base comprising a first contact portion and a transition portion, a contact member disposed between the base and the surface; and a biasing portion disposed between the first contact portion of the base and the surface. At least a first portion of an impact force upon the surface is transferred from the contact member to the base, and a second portion of the impact force is subsequently returned to the surface, the second portion being less than the first portion.

摘要: The present application provides a superimposed opposing wave spring that has a plurality of superimposed-layer wave spring units, wherein each layer in each superimposed-layer wave spring unit is formed by spirally bending around an axis into a wave shape, and waveforms of the respective layers in each superimposed-layer wave spring unit are arranged to overlap each other. At least one connection spring part, which connects two adjacent superimposed-layer wave spring units that are stacked one above the other, so that the two adjacent superimposed-layer wave spring units respectively have a first wave trough and a second wave crest that are abutting each other with opposing apexes, and respectively have a first wave crest and a second wave trough that are arranged across from each other in an upper position and a lower position.

摘要: A bowfishing arrow slide configured to slidably attach a bowfishing line to an arrow and configured to include a shock absorbing system to enhance the life of the slide is disclosed. The bowfishing arrow slide enables a bowfishing line to be slidably attached to the arrow to keep the arrow attached to a line reel even after being shot and to allow the slide to move from a preshot position at the tip of the arrow to the rear of the arrow during the shot for improved arrow flight. The bowfishing arrow slide may include a shock absorbing system on the bowfishing arrow slide whereby the shock absorbing system is configured to absorb impact forces created when the strikes a slide stop on an arrow shaft when the arrow is shot. The shock absorbing system reduces damage to the slide thereby enhancing the useful life of the slide.

摘要: A copper-coated steel wire includes: a core wire made of steel having a pearlite structure; and a coating layer covering a surface of the core wire and made of Cu or a Cu alloy. The steel contains C by greater than or equal to 0.5% by mass and less than or equal to 1.0% by mass, Si by greater than or equal to 0.1% by mass and less than or equal to 2.5% by mass, Mn by greater than or equal to 0.3% by mass and less than or equal to 0.9% by mass, and the balance consisting of Fe and inevitable impurities. In a cross section perpendicular to a longitudinal direction, a value of surface roughness Ra of the core wire is greater than or equal to 25% and less than or equal to 70% of a thickness of the coating layer.
