1. A ratcheting configuration for fastening of at least one lace by said lace ratcheting; wherein said ratcheting configuration comprising of at least one lace ratcheting device for fastening said lace by said lace ratcheting;
said lace ratcheting device comprises a channel; wherein said channel further comprising: a gripping wall, a top wall, a lower side wall and an upper side wall; wherein said channel further comprising: an entry opening and an exit opening; wherein a forwards direction in said channel is defined as direction from said entry opening to said exit opening; wherein a backwards direction in said channel is defined as direction from said exit opening to said entry opening;
wherein a turning gate is rotatably installed inside said channel; wherein said turning gate is made of solid material; wherein said turning gate comprising a front end and a rear end; wherein said turning gate has an axis of rotation, which is located between said front end and said rear end; wherein said turning gate is rotatably installed inside said channel using an axle which is fitted into a bearing; wherein axis of said axle coincides with said axis of rotation; wherein said gripping wall is positioned opposite to said front end; wherein said top wall is situated opposite to said gripping wall;
wherein a gap exists between said front end and said gripping wall; wherein said gap has a gap width; wherein said turning gate is installed at a predetermined diagonal direction with respect to said forwards direction; wherein at said diagonal direction said front end is closer to said exit opening than said axis of rotation; wherein at said diagonal direction said front end is closer to said gripping wall than said axis of rotation;
wherein a forwards turning is defined as turning of said turning gate in which said front end is moved in a combined said forwards direction plus laterally inwards direction; wherein said laterally inwards direction is directed away from said gripping wall; wherein motion in said laterally inwards direction increases said gap width; thereby, said forwards turning increases said gap width;
wherein a backwards turning is defined as turning of said turning gate in which said front end is moved in a combined said backwards direction plus laterally outwards direction; wherein said laterally outwards direction is directed towards said gripping wall; wherein motion in said laterally outwards direction decreases said gap width; thereby, said backwards turning decreases said gap width;
wherein a forwards motion is defined as motion in said forwards direction; wherein a backwards motion is defined as motion in said backwards direction; wherein a forwards force is a force in said forwards direction; wherein said forwards force applied to said front end is configured to cause said forwards turning; wherein a backwards force is a force in said backwards direction; wherein said backwards force applied to said front end is configured to cause said backwards turning;
wherein said lace ratcheting device has a ratchet mechanism which controls said gap width; wherein said ratchet mechanism has an inactive position and an active position; wherein said lace has a lace width; wherein at said inactive position said gap width is larger than said lace width; thereby, allowing said lace passing through said gap to be moved freely both in said forwards direction and in said backwards direction;
wherein at said active position said gap width is smaller than said lace width; whereby said lace passing through said gap is being squeezed between said front end of said turning gate and said gripping wall; wherein when said ratchet mechanism is in said active position, then moving said lace in said forwards direction also applies said forwards force on said front end due to friction; wherein said forwards force causes said forwards turning of said turning gate; thereby increasing said gap width and allowing easier said forwards motion of said lace; wherein when said ratchet mechanism is in said active position, then moving said lace in said backwards direction applies said backwards force on said front end due to friction; wherein said backwards force causes said backwards turning of said turning gate; thereby further decreasing said gap width and blocking any additional said backwards motion of said lace;
wherein when said ratchet mechanism is in said inactive position, said gap width is larger than said lace width; whereby said lace passing in said gap can be moved freely both in said forwards direction and in said backwards direction; thereby, when said ratchet mechanism is in said active position, said lace ratcheting device is a ratcheting device which enables said forwards motion of said lace for fastening but blocks said backwards motion of said lace;
whereby, when said ratchet mechanism is in said active position, said lace ratcheting device enables said lace fastening and keeps said lace fastened until said ratchet mechanism is switched into said inactive position;
wherein a torque spring has been installed in said channel; said torque spring has a resilient helical wire structure with a first wire end and a second wire end; wherein said torque spring is mounted on said axle; wherein said torque spring is installed preloaded with a bias which tends to cause said backwards turning of said turning gate; wherein, said backwards turning decreases said gap width and squeezes said lace in said gap;
wherein a lever is attached to said rear end; wherein said lever protrudes from an opening in said top wall; wherein said lever facilitates manual switching of said ratcheting mechanism from said active position into said inactive position when a user causes said forwards turning of said turning gate by applying on said lever a manual pressure which is high enough to overcome said bias; thereby, when said user does not apply said manual pressure on said lever and no said forwards force is applied on said front end, said bias is keeping said ratchet mechanism in said active position.
