Abstract
A shoe contains an adjustable space for the foot and several fluidically connected chambers. In order to adjust the space for the foot, the flowability of a magnetorheological fluid can be influenced by one or more devices that generate a magnetic field and thereby adjust the space for the foot resulting in a better fitting of the shoe. The novel system may also be implemented in orthoses (e.g., pronation correction) or in complete shoes with orthotics devices for correcting musculoskeletal abnormalities.
Claims25
A shoe with a foot space, comprising:
- one or more deformable chambers disposed to vary a shape and/or a volume of the foot space in the shoe;
- a supply container and one or more flow links fluidically connecting said supply container to respective said deformable chambers;
- an amount of magnetorheological fluid (MRF) in said supply container, in said one or more deformable chambers and in said one or more flow links;
- and
- at least one magnet device for generating a magnetic field, said magnet device being disposed to subject at least one of said flow links and said deformable chambers to the magnetic field, said magnet device selectively influencing a viscosity of said magnetorheological fluid and varying the shape and/or the volume of the foot space by varying the magnetic field.
2 more elements
Skiing equipment, comprising:
- a ski with a ski binding;
- a ski boot configured to be clamped to said ski binding, said ski boot having a foot space for receiving a foot of a skier, said ski boot including:
- a plurality of deformable chambers disposed to vary a shape and/or a volume of the foot space in the shoe;
- a supply container and one or more flow links fluidically connecting said supply container to said deformable chambers;
- an amount of magnetorheological fluid (MRF) in said supply container, in said deformable chambers and in said one or more flow links;
- at least one magnet device for generating a magnetic field disposed to subject at least one of said flow links to the magnetic field, said magnet device selectively influencing a viscosity of said magnetorheological fluid and varying the shape and/or the volume of the foot space by varying the magnetic field;
- and
- an electrical energy source connected to said magnet device for supplying electrical energy for energizing said magnet device.
