Automatically braking belay device with releaser

A belay device for controlling descent of a load along a rope comprising:

• a base plate with an attachment hole on one end and a spacer incorporating a spindle on the other end, and a magnetized jaw near the attachment hole, a cam assembly with a magnetized jaw on one end that meets the magnetized jaw of the base plate and an integrated and proprietarily shaped cam incorporating a protrusion at the other end which part is pivotably attached on axis to the base plate near the center of the base plate, with a designated path for placing the rope in the perimeter around the cam and in a gap between the cam and the spacer such that the rope travels freely along the path when the the magnetized jaws are met and when the rope pulls at a velocity beyond the normal feeding by hand, as a result of a sudden pull of the rope surrounding the cam rotates the cam assembly following the travel of the rope overcoming the magnetic force attaching the two magnetized jaws of the base plate and the cam assembly, at the same time closing the gap between the protruded part of the cam and the spacer to cause a brake, and
• a lowering handle pivotably attached to the cam assembly near the magnetized jaw such that the pulling of the lowering handle separates the magnetized jaw of the cam assembly from the magnetized prom of the base plate and rotates the cam on axis widening the gap between the cam and the spacer to allow the rope to travel,
• a cover plate pivotably attached on one end to the base plate at the spacer's spindle such that the cover plate is movable between an open and a closed position, and an attachment hole at the other end, such that when the cover plate is in the closed position, the attachment holes of the base plate and the cover plate are substantially aligned and an operator can lock the belay device in the closed position by inserting an attachment means through the attachment holes keeping the rope within designated path among the base plate, cam assembly and the cover plate, and in the open position, the rope may be inserted or taken out of the belaying device;
