Description

SPECTACLES

Technical Field

[1] The present invention relates to spectacles, and more particularly, to spectacles, which can enhance an effect of correcting a user's eyesight by preventing slip-down of the spectacles when the user wears them, and prevent a mark of a nose support from being left on the ridge of the nose by improving a supporting force of the spectacles.

[2] In addition, the present invention relates to spectacles, which can vary positions and lengths of a pair of temples according to the position of the user's ears, thereby allowing the user to easily wear the spectacles in stable regardless of the form of the user's face. Background Art

[3] In general, spectacles are mainly used to improve and correct a user's sight and also used to protect the user's eyes from ultraviolet rays, microwaves, heat rays, foreign matters, and so on transferred from the outside or to show the user's fashion.

[4] The spectacles include a pair of lenses, a pair of rim members respectively aligned on the circumferential surfaces of the lenses, a bridge located between the two rim members, a nose support located below the bridge, and a pair of temples hinge-coupled to sides of the rim members.

[5] In addition, besides the above structure, there are various attempts, for instance, the lenses are made of a plastic material in stead of a glass material to make the spectacles light. Moreover, to make the spectacles still lighter, the rim members located on the circumferential surfaces of the lenses are eliminated, the bridge is connected between the lenses, and the temples are hinge-coupled to the sides of the lenses.

[6] When the user wears the spectacles, the spectacles is prevented from being slipped down by a bearing power generated by end portions of the temples caught on the circumferential surface of the upper portion of the user's ears and a bearing power generated when the nose support is in contact with the ridge of the nose. However, since the nose support is slipped down from the ridge of the nose due to weights of the lenses and temples and the user's movement and the bearing power of the spectacles is weakened, the positions of the end portions of the temples caught on the user's ears are changed, and so, it causes a pain on the ears and the ridge of the nose and instability in a wearing state, lowers sight correction and complement effects and deteriorates the user's sight since the focus of the spectacles is deviated from the original position. Disclosure of Invention Technical Problem [7] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide spectacles, which have can prevent slip-down thereof when a user wears them and prevent a mark of a nose support on the ridge of the nose since a pair of temples are caught to the inner portion of the user's earflaps.

[8] It is another object of the present invention to provide spectacles, which can improve a sense of wearing since a pair of temples are caught to the inner portion of the user's earflaps and lengths and positions of the temples are varied by springs according to the positions of the user's ears.

[9] It is a further object of the present invention to provide spectacles, which include a pair of main temples caught to upper circumferential surfaces of the user's ears and a pair of auxiliary temples caught to the upper earflaps of the user's ears to thereby allow the user to wear the spectacles in stable, thereby correcting the user's sight and preventing lowering of the user's sight since the spectacles are not slip down and fixed at an exact position to be in complete focus. Technical Solution

[10] To achieve the first object, the present invention provides spectacles including a pair of lenses, a bridge for connecting the lenses or rim members mounted on the rims of the lenses with each other, and temples, wherein each temple includes: a main temple caught to the upper circumferential surface of the ear; and an auxiliary temple integrally formed at the central portion of the main temple, the auxiliary temple having a curved end portion caught to a groove formed on an earflap of the ear, the spectacles comprising a nose support mounted on the bridge and positioned on the uppermost portion of the ridge of the nose, whereby the spectacles provides a good wearing state and allows a user to easily and conveniently wear the spectacles on the ridge of the nose and ears.

[11] To achieve the second object, the present invention provides spectacles including a pair of lenses, a bridge for connecting the lenses or rim members mounted on the rims of the lenses with each other, and temples, wherein each temple includes: a main temple having a retaining portion mounted at an end thereof and caught to the user's ear and a spring mounted on the outer circumference of the other end thereof in such a way as not to be separated to the outside; and a temple-mounting member having a spring-mounting member, to which an end portion of the main temple having the spring is inserted, for compressing and expanding the spring according to forward and backward movements of the main temple, a mounting portion having an end hinge- coupled to a side of the lens or the rim member and the other end in which the spring- mounting member is movably mounted, a supporter fixed on an entrance of the mounting portion for passing the main temple therethrough, and a position-adjusting means mounted on a side of the mounting portion for fixing a location of the spring- mounting member.

[12] To achieve the third object, the present invention provides spectacles including: a pair of main temples caught to the upper circumferential surfaces of the user's ears; and a pair of auxiliary temples respectively mounted at central portions of the main temples in a length-adjustable manner, each auxiliary temple having a retaining portion formed at an end thereof and caught to a groove of the earflap so that the temples are doubly fixed on the upper circumferential surface of the user's ears and on the earflaps to thereby prevent slip-down of the spectacles.

[13] In the above, the position-adjusting means may be one selected from screws mounted on grooves formed on a side of the mounting portion, springs and balls going through the grooves, and so on.

Advantageous Effects

[14] As described above, the spectacles according to the present invention can remove a pain of the user's ears and reduce transformation and pain of the ears since the main temples and the auxiliary temples can disperse pressure by a load of the spectacles. In addition, the spectacles can provide a sight correction effect without lowering of the user's sight due to discordance between focuses since they can prevent slip-down thereof and fix a focusing position of lenses.

[15] Moreover, the spectacles according to the present invention can prevent a mark of a nose support on the user's ridge of the nose since the nose support is lightly put on the uppermost portion of the ridge of the nose.

[16] Furthermore, the spectacles according to the present invention can allow the user to wear them easily without regard to the user's facial form since the temples are adjustable in length and prevent an easy separation of end portions of the temples from the user's ears since the temples are elastically supported by the spring without a form- changing process, e.g. bending, of the temples according to the user's facial form, thereby increasing a good sense of wearing.

Mode for the Invention

[37] Reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings.

[38] FIGS. 1 to 5 illustrate spectacles according to a first preferred embodiment of the present invention. In the drawings, the spectacles according to the present invention includes a pair of lenses 1, a pair of rim members 2 respectively located on the circumferential surfaces of the lenses 1, a bridge 3 located between the two rim members 2, and a pair of temples 4 hinge-coupled to sides of the rim members 2.

[39] The temple 4 according to the first preferred embodiment of the present invention includes a main temple 140 caught to the upper circumference of a user's ear, and an auxiliary temple 150 mounted at the central portion of the main temple 140 and having a curved end portion caught to a groove 10a formed between an earflap and fossa triangularis auriculae of the user' ear 10. The main temple 140 and the auxiliary temple 150 may be made of metal or synthetic resin.

[40] In the meantime, the auxiliary temple 150 may be welded or injection-molded integrally with the main temple 140 as shown in FIGS. 1 and 2, or coupled to the main temple 140 via a hinge 41 as shown in FIG. 3 in such a way as to be pivotable on the main temple 140 in correspondence with a form of the ear. In this instance, since the auxiliary temple 150 may drop down easily if it is pivoted on the main temple 140 too easily, the auxiliary temple 150 is coupled to the main temple 140 in such a way as to be pivoted on the main temple 140 stiff.

[41] As another example shown in FIG. 4, the temple 4 further includes a coupling member 142 mounted at the central portion of the main temple 140 in such a way that the main temple 140 goes through the coupling member 142 and the auxiliary temple 150 is coupled to the coupling member 142. Here, the coupling member 142 may be completely fixed on the central portion of the main temple 140, but it is preferable that the coupling member 142 is aligned at the central portion of the main temple 140 in such a way as to be moved stiff.

[42] In addition, since the auxiliary temple 150 shown in FIG. 4 is pivotably mounted on the main temple 140 to allow the user to easily wear the spectacles, as shown in FIG. 5, an end portion of the auxiliary temple 150 is pivotably coupled to the coupling member 142 via a second hinge 143 so that the other end portion of the auxiliary temple 150 can be exactly caught to the groove 10a of the ear 10.

[43] Meanwhile, since the end portion of the auxiliary temple 150 may pressurize the ear

10 due to elasticity of the auxiliary temple 150, the end portion of the auxiliary temple 150 can be made of silicon or synthetic resin, which is not harmful to the human body to thereby remove a pain.

[44] In addition, a nose support 160 is mounted on the bridge 3 and aligned on the uppermost portion of the ridge 11 of the nose, and made of a soft and elastic material, such as silicon or synthetic resin, which is not harmful to the human body.

[45] It is clear that the above structure can be applied also to spectacles whose bridge 3 is connected between the two lenses 1 without the rim members 2.

[46] According to the first preferred embodiment having the above structure, since the main temple 140 is located on the upper circumferential surface of the ear 10 and the end portion of the auxiliary temple 150 is caught to the groove 10a of the ear 10, the spectacles are not easily slipped off even though the nose support 160 is lightly located on the uppermost portion of the ridge 11 of the nose. Moreover, since weight of the spectacles is dispersed by the auxiliary temples 150 to thereby disperse power pressing the ears 10, the spectacles according to the present invention can remove a pain on the ears and allow the nose support 160 to be located on the ridge 11 of the nose still lighter.

[47] Hereinafter, referring to FIGS. 6 to 10, spectacles according to a second preferred embodiment of the present invention will be described.

[48] The temple 4 according to the second preferred embodiment of the present invention includes a main temple 240 being movable in a longitudinal direction and having elasticity, and a temple-mounting member 242 hinge-coupled to the lens 2 or the rim member 3 mounted on the rim of the lens 2 for mounting the main temple 240 to the lens 2. Referring to FIGS. 6 and 7, the mounting structure of the spectacles according to the second preferred embodiment will be described.

[49] The main temple 240 has a curved end, and includes a retaining portion 240a mounted on the curved end and caught to the groove 10a of the ear 10 and a spring 240b mounted on the outer circumference of the other end thereof in such a way as not to be separated to the outside.

[50] The main temple 240, on which the spring 240b is mounted, is inserted into a spring-mounting member 240c, so that the spring 240b is compressed or expanded according to forward and backward movements of the main temple 240. For this, the spring-mounting member 240c is formed longer than the spring 240b, which is not compressed, and has a structure on both sides thereof in such a way as to restrict movements of the spring 240b and the main temple 240.

[51] As described above, the spring-mounting member 240c, to which the main temple

240 and the spring 240b are coupled, is inserted into the temple-mounting member 242, whose an end is hinge-coupled to the side of the lens 2 or the rim member 3, in such a way as to be moved forwardly or backwardly. The temple-mounting member 242 includes a mounting portion 242a in which the spring-mounting member 240c is movable, a supporter 242b, through which the main temple 240 passes, fixed at an entrance of the mounting portion 242a via a wedge or a screw 242c, and a screw 242d coupled to a side of the mounting portion 242a for fixing a position of the spring- mounting member 240c.

[52] So, the spring-mounting member 240c is moved inside the temple-mounting member 242 according to the position of the user's ear, and fixed by the screw 242d inserted and coupled from the side of the mounting portion 242a. The main temple 240 can be moved forwardly and backwardly with a tension by the spring 240b inside the spring-mounting member 240c.

[53] To adjust the location of the temples of the spectacles according to the location of the user's ear, first, the screw 242d is released to adjust the location of the spring- mounting member 240c, and then, the screw 242d is tightened to fix the spring- mounting member 240c so that the location of the longitudinal direction of the main temple 240 is adjusted.

[54] When the user wears the spectacles in the above state, since the main temples 240 caught to the grooves 10a of the ears 10 lightly pull the user's ears by the springs 240b, a worn state of the spectacles is stable and a sense of wearing becomes better.

[55] As shown in FIGS. 8 to 10, the spectacles according to the second embodiment may further include auxiliary temples 250 curved in correspondence with the grooves 10a of the ears 10. An example that the auxiliary temples 250 are mounted will be described in more detail as follows.

[56] First, as shown in FIG. 8, an auxiliary temple mounting portion 252a is formed on the temple-mounting member 242 in parallel with the mounting portion 242a of the temple-mounting member 242, and the auxiliary temple 250, like the main temple 240, includes a spring 250b, a spring-mounting member 250c, a supporter 252b fixed by a screw or a wedge 252c, and a screw 252d for fixing the auxiliary temple 250 to the auxiliary temple mounting portion 252a. In this instance, the screw 252d of the auxiliary temple mounting portion 252a is formed separately from the screw 242d of the main temple 240.

[57] The auxiliary temple 250 is elastically supported by the spring 250b in such a way that an end portion of the auxiliary temple 250 is caught to the groove 10a of the ear 10 and the other end portion of the auxiliary temple 250 is inserted to the spring-mounting member 250c.

[58] So, since the main temple 240 is caught to the upper portion of the groove 10a of the ear 10 and the end portion of the auxiliary temple 250 is caught to the lower portion of the groove 10a of the ear 10, weight of the spectacles is separately supported by the auxiliary temple 250, whereby power applied to the ear 10 is dispersed.

[59] In addition, the spectacles according to the second preferred embodiment allow the end portions of the main temples 240 and the auxiliary temples 250 to be exactly caught to the grooves 10a of the user's ears 10 by easily varying the locations of the main temples 240 and the auxiliary temples 250, and prevent that the end portions of the main temples 240 and the auxiliary temples 250 are easily separated from the grooves 10a by virtue of elasticity of the springs 240b and 250b.

[60] Referring to FIGS. 11 to 17, spectacles according to a third preferred embodiment of the present invention will be described.

[61] The spectacles according to the third preferred embodiment includes: a pair of main temples 340 caught to the upper circumferential surface of the ear 10; and auxiliary temples 350 respectively mounted at the central portions of the main temples 340 in a length-adjustable manner, each auxiliary temple having a retaining portion 350a formed at an end portion thereof and caught to the groove 10a of the ear 10. The auxiliary temple 350, like the auxiliary temple 250 of the second preferred embodiment, is mounted on the main temple 340 in such a way as to be adjustable in length by a spring 350b, a spring-mounting member 350c, a supporter 342b and a screw 342d.

[62] When the user wears the spectacles having the above structure, since the main temples 340 are located on the upper circumferential surfaces of the ears and the auxiliary temples 350 are fixed on the grooves 10a of the ears 10, the weight of the spectacles is dispersed to thereby prevent slip-down of the spectacles.

[63] Meanwhile, in the second and third preferred embodiments, the spring-mounting members 240c, 250c and 340c are fixed by the screws 242d, 252d and 342d, but may be fixed by one of various means, for instance, balls 242f, 252f and 342f or springs 242g, 252g and 342g, and it will be described referring to FIG. 17.

[64] The spring-mounting members 240c, 250c and 340c have a number of semicircular grooves 24Oe, 25Oe and 350e formed below the spring-mounting members at fixed intervals, and the mounting portions 242a, 252a and 342a have a number of grooves 242e, 252e and 342e corresponding to the grooves 24Oe, 25Oe and 350e and being deeper than the grooves 24Oe, 25Oe and 350e. The balls 242e, 252f and 342f and the springs 242g, 252g and 342g are inserted into the grooves 242e, 252e and 342e, so that the length of the main temples 240 or the auxiliary temples 250 or 350 is adjusted while the balls 242f, 252f and 342f are inserted to or separated from the grooves 24Oe, 25Oe or 350e of the main temples 240 or auxiliary temples 250 or 350 by a tension of the springs 242g, 252g or 342g.
