Patent number: 11849799Abstract: A shock absorber includes a three-dimensional structure composed of a unit structure repeatedly, regularly and continuously arranged in at least one direction, the unit structure being a three-dimensional shape formed by a wall having an external shape defined by a pair of parallel planes or curved surfaces. In the shock absorber, a differently shaped portion which does not correspond to the wall defining the unit structure is locally provided in a shock absorbing region which is a region in which the three-dimensional structure has the unit structure disposed.Type: GrantFiled: June 23, 2020Date of Patent: December 26, 2023Assignee: ASICS CORPORATIONInventors: Yutaro Iwasa, Masanori Sakamoto, Norihiko Taniguchi, Koji Shimomura

Patent number: 11832683Abstract: A shock absorber includes a three-dimensional structure composed of a unit structure repeatedly, regularly and continuously arranged in at least one direction, the unit structure being a three-dimensional shape formed by a wall having an external shape defined by a pair of parallel planes or curved surfaces. When the unit structure occupies a cuboidal space representing a unit space and defined by mutually orthogonal three sides having a first side extending in an axial direction in which the shock absorber exhibits a shock absorbing function as the shock absorber receives a load and second and third sides each extending from one end of the first side in a direction orthogonal to the axial direction, and the first side has a length L1 and a longer one of the second and third sides has a length L2, the shock absorber satisfies 1.1?L1/L2?4.0.Type: GrantFiled: June 23, 2020Date of Patent: December 5, 2023Assignee: ASICS CORPORATIONInventors: Masanori Sakamoto, Yutaro Iwasa, Norihiko Taniguchi, Koji Shimomura

Publication number: 20220408880Abstract: A shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces. The shock absorbing portion includes at least one three-dimensional structure body obtained by changing a shape of a unit structure body thickened based on a unit structure of a Schwartz P structure. The shape of the three-dimensional structure body in an unloaded state is a shape obtained by changing the shape of the unit structure so as to follow the shape change of the unit structure body, which is the regular hexahedron shaped space occupied by the unit structure body, into the trapezoidal space.Type: ApplicationFiled: June 23, 2022Publication date: December 29, 2022Applicant: ASICS CORPORATIONInventors: Yutaro IWASA, Yoshiyasu ANDO, Keita OZAWA

Publication number: 20220408878Abstract: A shoe sole includes a sole body including a midsole and a shock absorber. The shock absorber is disposed adjacent to the midsole in a direction intersecting a thickness direction of the sole body. The midsole includes a first opposing surface that is opposed to the shock absorber and inclined with respect to the thickness direction, and the shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces and a plate-shaped fixing wall including a second opposing surface opposed to the first opposing surface. The fixing wall is inclined with respect to the thickness direction such that the second opposing surface is parallel to the first opposing surface. The shock absorber is fixed to the midsole by bonding the first opposing surface and the second opposing surface through an adhesive layer.Type: ApplicationFiled: June 23, 2022Publication date: December 29, 2022Applicant: ASICS CORPORATIONInventors: Yutaro IWASA, Tomokazu HASHIBA, Keita OZAWA

Publication number: 20220202135Abstract: A shoe sole at least partially comprises a shock absorber, and the shock absorber that includes a shock absorbing portion and a cover portion that has a tread on a side opposite to the shock absorbing portion. The shock absorbing portion is provided with a plurality of pass-through portions passing through the shock absorbing portion as viewed in a direction of a normal to the tread, and the cover portion covers at least one of the plurality of pass-through portions. The cover portion is provided with a communication path having one end open to the pass-through portion and the other end open at the tread, and a condition of R<L is satisfied, where R represents a diameter of a largest virtual incircle of a contour line of an opening of the communication path located closer to the tread, and L represents a length of the communication path.Type: ApplicationFiled: December 22, 2021Publication date: June 30, 2022Applicant: ASICS CORPORATIONInventors: Masanori SAKAMOTO, Yutaro IWASA, Genki HATANO, Koji SHIMOMURA

Patent number: 11058170Abstract: There is provided a footwear capable of efficiently removing vibrations of specific frequencies that could propagate to the human body upon landing during running or walking. A footwear includes a sole; an upper connected to an upper-side perimeter region of the sole; and a vibration absorbing unit which absorbs vibration generated by an impact upon landing. The vibration absorbing unit includes a platy flexible support portion which has a smaller rigidity in the vertical direction than in the horizontal direction, and a weight portion provided in the support portion. The support portion is fixed to the sole or the upper, surrounding a perimeter of the weight portion.Type: GrantFiled: December 28, 2015Date of Patent: July 13, 2021Inventors: Tsuyoshi Nishiwaki, Sho Takamasu, Koki Matsuo, Yutaro Iwasa, Shigeyuki Mitsui, Katsunori Yagyu
