Abstract

New request updated 13/09/2016. A self-returning spring-loaded hinge consists of a bottom base, a first hinge plate sleeve, a second hinge plate sleeve, an upper boot, and a long screw that runs the entire length from the upper boot to the bottom base. An inner sleeve, a hollow cylindrical rod with a diameter matching the inner diameter of the first hinge plate sleeve, is inserted inside the inner sleeve and rests on the socket. The lower end of the spring rod engages with a vertical groove in the support shoulder. The first and second hinge plate sleeves fit over the inner sleeve. The sides of the upper boot have several evenly spaced adjustment slots. These slots help adjust the spring's flexibility. One slot is secured with an adjusting pin that acts as a support to automatically retract the second hinge plate.

New Request Updated 13/09/2016 1. Self-returning spring hinge consists of a bottom base (1) which is a hollow cylindrical rod with a vertical through hole in the center, where the middle top of the bottom base (1) is a socket (4) with a diameter smaller than the diameter of the bottom base (1), and on top of the socket (4) is a shoulder (6) with at least one vertical groove (7) for the positioning of the lower end of the spring rod (8), on one side of the bottom base (1) is drilled with a routing hole (2) for the fastening of a screw (3), and a first hinge sleeve (9) which is placed on the top edge of the bottom base (1), which is a hollow cylindrical rod with a diameter corresponding to the size The diameter of the bottom sleeve (1) where the sides of the first hinge plate sleeve (9) are welded to the first hinge plate (11), where the body of the first hinge plate (11) has several through holes (12) for fastening with screws. The second hinge plate sleeve (14) is a hollow cylindrical rod with a diameter corresponding to the diameter of the first hinge plate sleeve (9), where the sides of the second hinge plate sleeve (14) are welded to the second hinge plate (15), where the body of the second hinge plate sleeve (14) has several through holes (16) for fastening with screws, where the second hinge plate sleeve (14) is fitted over the top boot (17). The top boot (17) is a cylindrical rod with a vertical through hole in the center, where the lower center of the top boot (17) is a socket (19) with a diameter smaller than the diameter of the first hinge plate sleeve (9). The diameter of the top boot (17) and the bottom of the socket (19) form a shoulder (20) with at least one vertical groove (21) for the positioning of the upper end of the spring rod (8). A long screw (22) is inserted lengthwise from the top boot (17) to the bottom base (1), and is secured by a fastening screw (3) that is threaded through the fastening hole (2) of the bottom base (1) so that the bottom base (1), the first hinge sleeve (9), the second hinge sleeve (14) and the top boot (17) are fastened together. Notably, one side of the socket (4) has a ridge (5) protruding from the wall. The side of socket (4), where the length of the ridge (5) corresponds to the lateral distance between the bottom base (1) and socket (4), where the lower edge of the first hinge sleeve (9) is grooved (10) for fitting onto the ridge (5) of socket (4) to lock the first hinge sleeve (9) in place. The inner sleeve (13) is a hollow cylindrical rod with a corresponding diameter. With the inner diameter of the first hinge sleeve (9) and the inner area of the inner sleeve (13), a spring rod (8) is inserted inside the inner sleeve (13) and rests on the socket (4), with the lower end of the spring rod (8) fitting into the vertical groove (7) of the shoulder (6), on which the first hinge sleeve (9) and the second hinge sleeve (14) fit over the inner sleeve (13). Around the sides of the upper boot (17) are several equally spaced spur holes (18), which help to adjust the flexibility of the spring rod (8), and in one of the spur holes (18) is held in place by a spur adjustment pin (23) to support the second hinge plate (15) to automatically turn.
