Stretchable member for shoe and shoe including the stretchable member
A stretchable member includes: a flat base made of a stretchable knitted fabric; and a limiting part extending in a stretching direction of the base, formed integrally with the base while having both ends in a length direction knitted in, and fixed to, the base, and configured to limit stretch of the base. The limiting part is longer than the distance between fixing points at which the limiting part is fixed to the base in an unstretched state, and is made of a knitted fabric which has a flat band shape and which is configured to become slack with respect to the base when the base is in the unstretched state.
1. A stretchable member for a shoe, the stretchable member being usable in an upper of the shoe and comprising:
a flat base made of a stretchable knitted fabric; and
a limiting part extending in a stretching direction of the base, formed integrally with the base while having both ends in a length direction knitted in, and fixed to, the base, and configured to limit stretch of the base, wherein
the limiting part is longer than a distance between fixing points at which the limiting part is fixed to the base in an unstretched state, and is made of a knitted fabric which has a flat band shape and which is configured to become slack with respect to the base when the base is in the unstretched state,
the limiting part comprises a plurality of limiting parts, and
ends of each of the plurality of limiting parts are joined to ends of adjacent ones of the plurality of limiting parts at associated ones of the fixing points at which the plurality of limiting parts are fixed to the base, such that the plurality of limiting parts, which are joined to each other in series, form at least one continuous row in the stretching direction of the base.
2. The stretchable member of claim 1 , wherein
the limiting part has a width of 1 mm or more.
3. The stretchable member of claim 1 , wherein
the at least one row of the plurality of limiting parts comprise a plurality of rows of the plurality of limiting parts, and
the plurality of rows of the plurality of limiting parts are arranged side by side at intervals in a direction perpendicular to the stretching direction of the base.
4. The stretchable member of claim 1 , wherein
the limiting part is made of a knitted fabric which is less stretchable than the base.
5. The stretchable member of claim 1 , wherein
a plurality of holes which are deformable in accordance with the stretch and contraction of the base are formed to be spaced apart from each other in the base.
6. A shoe including the stretchable member of claim 1 arranged in a portion, of the upper, corresponding to a forefoot of a wearer.
7. A shoe including the stretchable member of claim 2 arranged in a portion, of the upper, corresponding to a forefoot of a wearer.
8. A shoe including the stretchable member of claim 3 arranged in a portion, of the upper, corresponding to a forefoot of a wearer.
