Abstract
Boot or footwear sole structures and assemblies adaptable to various conditions where components are fixed to the sole between the heel and the toe portions of the boot by the forced interaction of opposed bearing surfaces on the components, with supporting areas or bearing profiles formed in the sole on respective sides of an opening that is provided between the heel and toe portions. The components stiffen the sole when assembled, and in addition portions thereof can be specially adapted for particular uses, such as climbing spikes, ice crampons, skates or ski bindings, thereby giving the boot sole structures varied adaptability and interchangeability to various modes of activities.
Claims15
A boot sole structure for stiffening the sole (12, 55) of a boot (10, 51) in an arch area (14) of the sole between heel (17) and toe (18) portions thereof, the structure comprising:
- a bracket assembly (15) including at least two bearing members (31/32;
- 31, 32/35;
- 31, 32/35, 35), braced against corresponding support surfaces (23, 24) on respective opposed supporting portions (20, 22) of the sole, which surfaces at least partly flank the arch area, said members having respective contact surfaces (37, 38) thereon, and means (34, 36, 36') for interlocking one of said members in its assembled condition with respect to at least one other member.
A boot sole structure for stiffening the sole (12, 55) of a boot (10, 51) in an arch area (14) of the sole between heel (17) and toe (18) portions thereof, the structure comprising:
- a bracket assembly (15) including three bearing members (31, 32/35), braced against corresponding support surfaces (23, 24) on respective opposed supporting portions (20, 22) of the sole, which surfaces at least partly flank the arch area, said members having respective contact surfaces (37, 38) thereon, and means (34, 36, 36'), for interlocking one of said members in its assembled condition with respect to at least one other member, wherein said three bearing members have at least one pair of said contact surfaces thereon, in pivotable but angularly different directions, which allow the bracing of said members against said support surfaces when said members are interlocked as aforesaid.
A boot sole structure for stiffening the sole (12, 55) of a boot (10, 51) in an arch area (14) of the sole between heel (17) and toe (18) portions thereof, the structure comprising:
- a bracket assembly (15) including at least two bearing members (31/32;
- 31, 32/35;
- 31, 32/35, 35), braced against corresponding support surfaces (23, 24) on respective opposed supporting portions (20, 22) of the sole, which surfaces at least partly flank the arch area, said members having respective contact surfaces (37, 38) thereon, and means (34, 36, 36') for interlocking one of said members in its assembled condition with respect to at least one other member, wherein said support surfaces are wider in at least one area than in other areas, for securely gripping said bracket assembly therebetween.
A boot sole structure for stiffening the sole (12, 55) of a boot (10, 51) in an arch area (14) of the sole between heel (17) and toe (18) portions thereof, the structure comprising:
- a bracket assembly (15) including two pairs of bearing members (31, 32/35, 35), braced against corresponding support surfaces (23, 24) on respective opposed supporting portions (20, 22) of the sole, which surfaces at least partly flank the arch area, said members having respective contact surfaces (37, 38) thereon, and means (34, 36, 36') for interlocking one of said members in its assembled condition with respect to at least one other member, wherein said pairs of bearing members are in the form of two bracket members (35) and two longitudinally engageable bearing brackets (31, 32), said bracket members straddling said bearing brackets while said brackets partly protrude from between said bracket members.
A boot sole structure for removeably attaching to the sole (12, 55) of a boot (51) at least one auxiliary attachment (45/48, 59) in an arch area (14) of the sole between heel (17) and toe (18) portions thereof, to adapt the boot for particular uses, the structure comprising:
- a bracket assembly (15) including at least two bearing members (31/32;
- 31, 32/35;
- 31, 32/35, 35), braced against corresponding support surfaces (23, 24) on respective opposed supporting portions (20, 22) of the sole, which surfaces at least partly flank the arch area, said members having respective contact surfaces (37, 38) thereon, and means (34, 36, 36') for interlocking one of said members in its assembled condition with respect to at least one other member.
