View Patent ↗A boot which has a tongue structure which includes at least first and second cables attached to the sides of the tongue, a guide channel associated with each cable, and a cable tensioning device connected to the cables and which is movable between first and second positions to respectfully tighten and loosen the cables. The tongue structure acts to maintain the foot in the boot and in a preferred embodiment, the tongue includes an outer somewhat rigid shell and an inner elastic layer.
1. A tongue structure for use in boot, said tongue structure comprising an upper layer formed of a rigid protective material, a lower layer formed of a resilient stretchable material, said upper layer being secured to said lower layer along marginal side edges thereof, said upper layer being spaced from said lower layer intermediate said side marginal edges to thereby provide an air space between said upper and lower layers, the arrangement being such that when said tongue is used in a boot, the foot of a user will contact said lower layer with said upper layer being spaced therefrom in a central region.
2. The tongue structure of claim 1 wherein said lower layer is formed of a rubber material.
3. The tongue structure of claim 1 wherein said upper layer is formed of a plastic material, said upper layer being resilient such that when pressure is applied to a central portion thereof, said side marginal edges will move apart.
4. The tongue structure of claim 3 wherein said upper and lower layers are spaced apart a distance of between 1 cm and 3 cm at a central portion intermediate said side marginal edges.
5. In an ice skate having a boot, a blade support portion mounted on said boot, and a blade mounted in said blade support portion, the improvement comprising a first cable member connected to an upper front portion of said blade, a second cable member being secured to an upper rear portion of said blade, said first and second cable members extending through said blade support portion and being connected to each other.
6. The improvement of claim 5 wherein said first and second cable members are adjustably connected together by tensioning means, said tensioning means being operative to adjust the tension on said cables.
7. The improvement of claim 6 wherein said boot has an aperture in a sole portion thereof, said aperture providing access to said cable tensioning means within said blade support member.
8. The improvement of claim 5 wherein, said boot has a sole portion, a plurality of screw threaded members extending through said sole portion to attach said boot and said blade support member together.
9. The improvement of claim 8 further including at least one shim member mounted between said sole and said blade support member.
10. The improvement of claim 8 wherein said blade support member has a front section secured to said boot and a rear section secured to said boot, said front and rear sections being spaced apart.
