A ratcheting device configured for fastening a belt;
- wherein the ratcheting device comprising:
- a channel, a turning gate, a blade, a lever and an operating part;
- wherein the channel is being configured to carry through a portion of the belt;
- the channel further comprises a gripping wall being adapted with a gripping surface configured to engage the belt;
- the ratcheting device has an active state and an inactive state;
- while in the active state, the ratcheting device is configured to restrict translation of the belt in the channel in a backward direction and to facilitate translation of the belt in the channel in a forward direction;
- while in the inactive state, the ratcheting device is configured to facilitate translation of the belt both in the forward direction and in the backward direction;
- the turning gate being rotationally engaged with the channel and turns around an axis which serves as a fulcrum;
- wherein the turning gate comprises an axle centered at the axis;
- wherein the axle is merged with a bar except for a left axle end which protrudes from a left bar's end and a right axle end which protrudes from a right bar's end;
- wherein the turning gate comprises a blade holder which is attached to the bar;
- wherein the blade includes a blade front;
- wherein the blade is installed into the blade holder such that the blade front protrudes in a front of the blade holder;
- the turning gate is installed in the channel such that a straight line emanating from the blade front and passing through the fulcrum is at an obtuse angle with respect to the forward direction;
- wherein
- the blade front is disposed within the channel opposite the gripping wall such that there is a gap between the blade front and the gripping wall;
- wherein the belt is configured to pass through the gap;
- the turning gate is configured to reduce the gap and to increase a pressure force exerted by the blade front on the belt when the turning gate is turned increasingly backward;
- wherein the turning gate is configured to increase the gap and to reduce the pressure force exerted by the blade front on the belt when the turning gate is turned increasingly forward;
- at the active state, the blade front is configured to exert the pressure force on the belt and the blade front is configured to frictionally engage the belt and to turn the turning gate forward when the belt is translated in the forward direction;
- wherein at the active state the blade front is configured to frictionally engage the belt and to turn the turning gate backward when the belt is translated in the backward direction;
- wherein at the active state the turning gate is configured to facilitate forward translation of the belt by turning increasingly forward while diminishing the pressure force of the blade front on the belt;
- wherein at the active state the turning gate is configured to restrict backward translation of the belt by turning increasingly backward while increasing the pressure force of the blade front on the belt;
- at the inactive state of the ratcheting device, the blade front is configured not to apply the pressure force on the belt and translation of the belt is facilitated both in the forward direction and in the backward direction;
- wherein the lever is flexibly connected to the turning gate via the operating part;
- wherein the lever is configured to switch the ratcheting device into the active state when the turning gate has been pulled by the lever and has been turned backward when the lever has been moved into an active lever position;
- wherein the lever is configured to switch the ratcheting device into the inactive state when the turning gate has been pushed by the lever and has been turned forward when the lever has been moved into an inactive lever position.
