US Patent 10329819 Adjustable spring hinge and gate

A gate has an adjustable spring hinge with an L-shaped member joining a first bracket to a second bracket by a rotatable bolt that extends through the L-shaped member and threadingly engages a sleeve. One end of the L-shaped member is coupled to the adjustable spring hinge, which is coupled to one of the two brackets. The other of the two brackets includes the sleeve that engages a threaded shaft of the bolt. Thus, a gap width between the first bracket and the second bracket is adjusted by rotating the bolt in a first direction or a second direction, opposite of the first direction.
