Publication number: 20220079781Abstract: Prosthetic feet and foot covers that provide a more natural appearance and improved performance are provided. A foot element for a prosthetic foot can extend from a heel end to a toe end and include a heel, arch, forefoot, and toe regions. The forefoot region can be wider than the arch and heel regions. The toe region can include a U-shaped cut out to define a big toe. Various features of the foot element can guide rollover of the foot through the big toe during use. A foot cover can be designed to receive a prosthetic foot including such a foot element. The foot cover can have a region of increased flexibility at a transition between the forefoot region and toe region. The foot cover can also have a padded area extending from the heel region across a lateral part of the arch region and forefoot region.Type: ApplicationFiled: September 24, 2021Publication date: March 17, 2022Inventors: Arinbjorn Viggo Clausen, Ragnar Örn Gunnarsson, Bjarni Andresson, Larus Gunnsteinsson, Rowan Patrick Robinson Cain

Patent number: 10864092Abstract: An attachment for a prosthetic foot comprising an attachment surface that couples to the edges of a foot plate of a prosthetic foot and an outer surface that functionally or cosmetically alters the foot plate of the prosthetic foot in order to adapt the prosthetic foot to the needs of the user. In another embodiment, a toe attachment for a prosthetic foot comprising a cavity that can receive the toe end of an elongate foot element of a prosthetic foot, the toe attachment that can functionally or cosmetically alter the elongate foot element in order to adapt the prosthetic foot to the needs of the user. In yet another embodiment, a seal cover that can removably engage a prosthetic foot and a cosmetic cover for a prosthetic foot, resulting in a substantially watertight connection between the seal cover and the prosthesis and the seal cover and the cosmesis.Type: GrantFiled: August 11, 2017Date of Patent: December 15, 2020Assignee: Össur Iceland ehfInventors: Christophe Guy Lecomte, María Guðrún Sveinbjörnsdóttir, Ragnar Örn Gunnarsson

Patent number: 10252771Abstract: A clipless pedal platform adapter can include first and second platforms. Each platform can have an outer side to interface with a user's foot and an inner side to interface with a clipless pedal, the inner sides facing one another. First and second side members can also be pivotally coupled to the first and second platforms at opposite ends of the platforms such that a distance between the platforms is variable. The first and second platforms and the first and second side members can define a pedal opening to receive the pedal. The first and second platforms can be biased toward one another to force the inner sides against the pedal thereby coupling the clipless pedal platform adapter to the pedal.Type: GrantFiled: November 10, 2017Date of Patent: April 9, 2019Assignee: K88 ehf.Inventors: Karl Birgir Björnsson, Ragnar Örn Gunnarsson

Publication number: 20190000659Abstract: A structure assembled by first and second stackable layers having properties allowing for the first and second stackable layers to be shaped into at least first and second different shapes, and at least one fastener to releasably secure the first and second stackable layers together in one of the at least first and second shapes in a semi-rigid or rigid, and unitary construction. The first and second stackable layers are secured into one of the at least first and second shapes by the at least one fastener to form a semi-rigid or rigid, and unitary construction.Type: ApplicationFiled: July 3, 2018Publication date: January 3, 2019Inventors: Martin Lund STORUP, Andrew BACHE, Christophe Guy LECOMTE, Arinbjorn CLAUSEN, Larus GUNNSTEINSSON, Felix STARKER, Ragnar Örn GUNNARSSON
