Abstract:
1. A buckle-lace fastening device for fastening laces, comprising a multiplicity of channels; wherein each said channel has an upper part and a lower part, said upper part is rotatably mounted on said lower part in which said upper part is able to turn with respect to said lower part; wherein each said channel has an entry opening and an exit opening; wherein a forward direction in each said channel is defined as the direction from said entry opening to said exit opening; wherein a backward direction in each said channel is defined as the direction from said exit opening to said entry opening; wherein each said channel has a resilient gate; wherein said resilient gate is made of a resilient and flexible material; wherein said resilient gate has a rear end and a front end; wherein said resilient gate is attached to said channel by attaching said rear end to said upper part of said channel and leaving said front end unattached; wherein each said lower part of said channel has an opposite wall situated opposite said front end; wherein said resilient gate is installed at a predetermined diagonal direction with respect to said forward direction; wherein at said diagonal direction said front end is closer to said exit opening than said rear end; wherein at said diagonal direction said front end is closer to said opposite wall than said rear end; wherein a gap exists between said front end of said resilient gate and said opposite wall of said lower part; wherein a force applied to said front end in said forward direction can move said front end in combined forwards plus laterally inwards directions by bending said resilient gate; wherein a force applied to said front end in said backward direction can move said front end in combined backwards plus laterally outwards directions by bending said resilient gate; wherein said gap can be widened and narrowed by a locking mechanism; wherein said locking mechanism has an opened position and a closed position; wherein at said opened position said gap is wide enough to allow said lace passing through said gap to move freely both in said forward direction and in said backward direction; wherein at said closed position said gap is narrower than a width of said lace, thereby said lace passing through said gap is being squeezed between said front end of said resilient gate and said opposite wall; wherein said front end can be moved towards or away from said opposite wall when said upper said upper part is turned towards or away with respect to said lower part, respectively, thereby narrowing or widening said gap, respectively; wherein said locking mechanism switches from said opened position into said closed position by turning said upper part towards said lower part such that said front end moves towards said opposite wall, thereby narrowing said gap more than said width of said lace such that said lace passing through said gap is squeezed between said front end and said opposite wall; and wherein said locking mechanism switches from said closed position into said opened position by turning said upper part away from said lower part such that said front end moves away from said opposite wall, thereby widening said gap more than said width of said lace such that said lace passing through said gap can be moved freely in said backward direction and in said forward direction.
