Abstract
An inline frame for an inline skate, designed to mimic the properties of an ice hockey skate blade on ice. The inline frame includes at least one first connection part intended to be connected to a boot and at least two wheels positioned essentially in the inline frame's longitudinal direction. The unique thing about the inline frame is that it includes an upper chassis section and a lower chassis section which via a coupling element are arranged to be rotatable in the inline frame's longitudinal direction, and that the upper chassis section includes at least one first contact surface and that the lower chassis section includes at least one second contact surface, where at least one of the first contact surface and the second contact surface is curvilinear.
Claims41
An inline frame for inline skates, comprising:
- an upper chassis section;
- a lower chassis section;
- and
- at least a first coupling element, the first coupling element including a first portion and a second portion, the upper chassis section and the lower chassis section being engaged by way of the first coupling element such that the first coupling element holds the upper chassis section and the lower chassis section together,
- wherein the upper chassis section and the lower chassis section are arranged to rock relative to each other along a longitudinal direction of the inline frame such that,
- when the upper chassis section rocks in a forwards direction relative to a neutral position, compression of the first portion of the first coupling element increases, and
- when the upper chassis section rocks in a backwards direction relative to the neutral position, compression of the second portion of the first coupling element increases,
- the inline frame comprising a first contact surface and a second contact surface, of which at least one is curvilinear, which are arranged to bear against each other, and arranged such that during relative rocking of the upper chassis section and lower chassis section, the first contact surface and the second contact surface rock against each other,
- wherein said first contact surface is a surface of the upper chassis section, said second contact surface is a surface of the lower chassis section, said first contact surface is curvilinear, and said second contact surface is flat.
