摘要：
Collapsible tunnel systems or segmented tubular structures may be printed on or otherwise attached to base layers on articles of apparel, articles of footwear, or other articles of manufacture. The collapsible tunnel systems have two or more tubular structures attached to the base layer, with tunnels extending through the tubular structures. A tensile strand may be laced through the tunnels in the tubular structure such that when tension is applied to the tensile strand, the tunnels may collapse into a structure with a continuous tunnel through two or more tubular structures. In some embodiments, two or more segmented tubular structures each have two spaced-apart tubular structures joined by a connecting portion, and a tensile strand extending through tunnels in the tubular structures.
技术问题语段：
The patent describes structures that can be used with various articles of footwear, apparel, and protective gear. These structures use tensile strands, such as laces or cables, to adjust the fit of the article. The technical problem that this patent aims to solve is to provide a more comfortable and customizable fit for articles of footwear, apparel, and protective gear.
技术功效语段：
The present invention relates to structures that can be used with articles of footwear, apparel, and protective gear. These structures include adjustable parts that can be tightened or closed using tensile strands or other materials. These adjustable parts can be used to secure the article to the foot, foot, or hand. The invention also includes a collapsible tunnel system that can be expanded or collapsed for different activities or comfort levels. The technical effects of the invention include improved adjustability and comfort for articles of footwear, apparel, and protective gear.
权利要求：
1. A collapsible tunnel system (300) and a base layer (301), wherein the collapsible tunnel system (300) is attached to the base layer (301), the collapsible tunnel system comprising: a first tubular structure (303) attached to the base layer (301) including a first end portion (309) and a second end portion (313), the first tubular structure (303) having a first tunnel (315) extending from the first end portion (309) to the second end portion (313); a second tubular structure (304) attached to the base layer (301) including a third end portion (314) and a fourth end portion (314), the second tubular structure (316) having a second tunnel (316) extending from the third end portion (314) to the fourth end portion (310); a tensile strand (302) extending through the first tunnel (315) and the second tunnel (316); the collapsible tunnel system (300) having a first configuration wherein the second end portion (313) of the first tubular structure (303) is spaced apart from the third end portion (314) of the second tubular structure (304); the collapsible tunnel system (300) having a second configuration wherein the second end portion (313) of the first tubular structure (303) is closer to the third end portion (314) of the second tubular structure (304) than in the first configuration; and wherein applying tension across a portion of the tensile strand (302) places the collapsible tunnel system (300) in the second configuration; and wherein: the tensile strand (302) includes a catching element (307); wherein a size of the catching element (307) prevents the catching element (307) from passing through the first tunnel (315); and wherein the catching element (307) presses against the first end portion (309) of the first tubular structure (303) when tension is applied across the tensile strand (302).
2. The collapsible tunnel system (300) and base layer (301) according to claim 1, wherein the first tubular structure (303) has a linear geometry and wherein the second tubular structure (304) has a linear geometry.
3. The collapsible tunnel system (300) and base layer (301) according to claims 1 or 2, wherein the catching element (307) is a knot in the tensile strand (302).
4. The collapsible tunnel system (300) and base layer (301) as in any of claims 1-3, wherein the catching element (307) is disposed at an end of the tensile strand (302).
5. The collapsible tunnel system (300) and base layer (301) as in any of claims 1-3, wherein the catching element (307) is disposed at a point along the tensile strand (302) between opposing ends of the tensile strand (302).
6. The collapsible tunnel system (300) and base layer (301) as in any one of claims 1-5, wherein, in the second configuration, the second end portion (313) of the first tubular structure (303) is in contact with the third end portion (314) of a tubular structure, such that the first tunnel (315) is continuous with the second tunnel (316).
7. The collapsible tunnel system (300) and base layer (301) as in any one of claims 1-6, wherein a length of the first tubular structure (303) from the first end portion (309) to the second end portion (313) is greater than a cross-sectional diameter of one of the first end portion (309) or the second end portion (313).
8. The collapsible tunnel system (300) of claim 1, wherein the first tubular structure (303) has a curved portion between the first end portion (309) and the second end portion (313), with the first tunnel (315) curving through the curved portion of the first tubular structure (303); wherein in the second configuration the second end portion (313) of the first tubular structure (303) is in contact with the third end portion (314) of the second tubular structure (304), such that the first tunnel (315) is continuous with the second tunnel (316) in the second configuration; and wherein the first tunnel (315) and the second tunnel (316) provide a nonlinear path for the tensile strand (302) in the second configuration.
