[24] According to the present invention, referring to a state where the auxiliary eyeglasses are opened in front, an eyeglasses assembly having primary eyeglasses and auxiliary eyeglasses using a hinge function will be described. [25] Referring to Figs. 1 to 3, a magnet structure of an eyeglasses assembly having primary eyeglasses and auxiliary eyeglasses includes a primary magnet part 13 protruding from the upper portion of a lens rim 12 of the primary eyeglasses 10 inwardly and having a primary magnet 13m inserted into the primary magnet part 13, and a magnet hinge part 23 bent from a portion of a lens rim 22 of the auxiliary eyeglasses 20 toward the primary eyeglasses 10 and corresponding to the upper surface 13a of the primary magnet part 13. Wien a closing magnet 23m inserted into a closing hinge part 23a, which horizontally protrudes toward the inside of the eyeglasses reacts with the upper surface 13a of the primary magnet part 13 by mutual magnet force and the primary eyeglasses 10 and the auxiliary eyeglasses 20 are combined with each other, the auxiliary eyeglasses 20 can maintain a closed state in such a fashion that the auxiliary eyeglasses 20 are hung on the lens rim 12 of the primary eyeglasses 10. As shown in Figs. 2 and 3, when a user forcibly lifts the auxiliary eyeglasses 20 upwardly in a state where the auxiliary eyeglasses 20 are closably secured to the primary eyeglasses 10 in front, the combining force between the upper surface 13a of the primary magnet part 13 into which the primary magnet 13m is inserted and the closing hinge part 23a of the magnet hinge part 23 of the lens rim 22 of the auxiliary eyeglasses 20 is removed, and at the same time, an opening hinge part 23b bent in such a fashion as to surround the primary magnet part 13 comes into close contact with a lower surface 13b of the primary magnet part 13. Finally, the primary magnet 13m of the lower surface 13b of the primary magnet part 13 of the primary eyeglasses 10 and an opening magnet 23m' mounted in the opening hinge part 23b of the magnet hinge part 23 of the auxiliary eyeglasses 20 are reacted and combined to each other by magnetic force, so that the auxiliary eyeglasses 20 can openably secured to the upper portion of the primary eyeglasses and maintain the opened state. On the contrary, when the user forcibly lowers the auxiliary eyeglasses 20 in the front direction of the primary eyeglasses 10 in the opened state of the auxiliary eyeglasses 20, the combining force of the closing magnet 23m is removed by the user's power, and at the same time, the closing hinge part 23a of the auxiliary magnet hinge part 23 is bent and approaches toward the upper surface 13a of the primary magnet part 13 of the primary eyeglasses 10. Finally, the primary magnet 13m of the primary magnet part 13 of the primary eyeglasses 10 and the closing magnet 23m of the closing hinge part 23a of the auxiliary magnet hinge part 23 are combined with each other, and so, the auxiliary eyeglasses 20 can be closably secured to the primary eyeglasses 10 in front and maintain the closed state. [26] As described above, there are lots of eyeglasses assemblies, each of which has primary eyeglasses and auxiliary eyeglasses openable and closable using the hinge function of the magnets. To combine the magnet of the primary eyeglasses and the magnets of the auxiliary eyeglasses, the present invention includes an auxiliary closing magnet (c) and a primary closing magnet (c1) which are operated upon the closing of the auxiliary eyeglasses and an auxiliary opening magnet (p) and a primary opening magnet (p1) which are operated upon the opening of the auxiliary eyeglasses. The auxiliary closing magnet(c) and the auxiliary opening magnet (p) are mounted on a magnet hinge part 100 of the auxiliary eyeglass, and the primary closing magnet (c1) and the primary opening magnet (p1) are mounted on a magnet part 300 of the primary eyeglasses. Therefore, the present invention includes the magnets functioning differently according to the opening and closing of the auxiliary eyeglasses so as to increase securing force and extend the lifespan of the magnets. [27] Referring to Figs. 4 to 7, the structure and operation of the magnets will be described in detail. [28] As shown in Figs. 4 and 8, the magnet hinge part 100 of the lens rim of the auxiliary eyeglasses is in the form of a rectangular parallelepiped bar, the auxiliary closing magnet (c) is mounted on the closing hirige part located at the lower surface of the magnet hinge part 100, and the auxiliary opening magnet (p) is mounted on the opening hinge part toward the primary eyeglasses. [29] As shown in Figs. 5 and 9, unlike the conventional eyeglasses assembly which has only one primary magnet combined with the auxiliary magnet without regard to opening and closing of the auxiliary eyeglasses, the magnet part 300 of the primary eyeglasses combined with the magnet hinge part 100 of the lens rim of the auxiliary eyeglasses according to the present invention includes a primary closing magnet (c1) mounted on the corresponding surface thereof on which the auxiliary closing magnet (c) is put and secured, and a primary opening magnet (p1) mounted on a bent portion downwardly bent at a certain angles toward the inside of the primary eyeglasses. [30] As shown in Figs. 6, 10 and 11, the auxiliary closing magnet (c) is mounted on the lower surface of the magnet hinge part 100 and is put and secured on the primary closing magnet (c'), at which time, the auxiliary opening magnet (p) is directed toward the inside of the primary eyeglasses. [31] As shown in Figs. 7, 10 and 11, when the user lifts the auxiliary eyeglasses upwardly, the combining force between the two magnets (c and c') combined with each other during the closirg of the auxiliary eyeglasses is released, and at the same time, the magnet hinge part 100 of the auxiliary eyeglasses is generally bent and pushed inwardly, so that the auxiliary opening magnet (p) is combined with the primary opening magnet (pr) mounted on the bent portion bent toward the inside of the magnet part 300 of the primary eyeglasses, and thus the auxiliary eyeglasses can be opened.
