ABSTRACT:
A method of adjusting an adjustable self closing hinge and the hinge which comprises providing an adjustable, self closing hinge. The hinge includes a tube with a hollow interior portion of circular cross section, a first end portion and a second end portion. A spring is disposed in the tube along its axis and has a spring end extending toward the first end portion and a second secured spring end extending toward the second end portion. A depression is provided at the first end portion of the tube extending into the hollow portion and a rotatable member is disposed within the hollow portion at the first end portion thereof and rotatable therein for adjusting the torque of the spring. The rotatable member is secured to the first spring end and has a flat wall portion at the end portion of the rotatable member opposing the spring and parallel to the axis, the wall and the rotatable member together forming a seat in the rotatable member. The depression is normally disposed against the seat and opposes the wall to prevent movement of the rotatable member out of the tube and rotation of the tubular member within the tube. A force is applied to the rotatable member along the axis to depress the rotatable member into the hollow interior portion until the wall is no longer disposed opposing the depression and is beneath the depression. The rotatable member is than rotated until a seat is again disposed directly over the depression and the force is than removed from the rotatable member so that the depression again rests on the seat and opposed to the side wall.
