Description

Description GLASSES WITH LENGTH-ADJUSTABLE TEMPLES

Technical Field

[1] The present invention relates to glasses with length-adjustable temples, and more particularly to glasses with length-adjustable temples, in which temples are adjustable in length according to physical conditions of a user. Background Art

[2] In general, glasses have temples connected at both sides of lenses or base frame for a user to wear the glasses on his face comfortably.

[3] The temples are foldable by means of hinges for easy carrying or management.

[4] As for the temples, ferrous steel materials and synthetic resin materials have been widely used.

[5] In the case of manufacturing the temples with the ferrous steel materials, two or more elements respectively formed of different materials may be coupled with each other at hooks of the temples in such a manner that elements formed of synthetic resin materials for easy deformation and comfort wearing are connected to the hooks of the temples.

[6] In the meantime, the temples formed of the synthetic resin materials have advantages of cost-saving and easy handling, so that such the temples may be manufactured with various size and shape and widely delivered to opticians.

[7] Further, the glasses having the temples with the synthetic resin portions may be selected by users with approximation in the length of the temples or the width between the temples and adjusted properly by heating the synthetic resin parts of the temples with a heater, which is equipped in the opticians, at a proper deformation temperature for correcting the shape and positions of the hooks as desired, so that the user may wear the glasses after proper fitting to his face.

[8] In the recent days, however, high cost materials, which are not adjustable in the shape and size not only in the opticians but also even in glasses manufactures have been widely spread out.

[9] That is, wooden materials, tortoise shells, horns, jewelry, shape-memory materials and super elastic materials, which are impossible or difficult in the adjustment of shape and size, have been employed for order-made glasses in manufacturers, and provided to users after the adjustment of width between the temples or length of the temples.

[10] Therefore, glasses made of stiff materials, the shape-memory materials and the super elastic materials which are impossible in the length adjustment or the shape deformation in opticians as described above have been circulated to users in the order- made manner only.

[11] However, if the temples are damaged or correction of the length is required during use, the glasses cannot be corrected by the opticians and the like.

[12] Therefore, the glasses are returned to manufacturers thereof and got back by the users after the correction, wherein these procedure causes inconvenience in use so that the glasses formed of the stiff materials, the shape-memory materials and the super elastic materials could not been widely spread in spite of increasing demands thereon.

[13] In general, the damage of the glasses is generated in the temples mainly. However, places to repair the damaged glasses are limited, so that the users have to request costly and time consuming outside services incurring economical and temporal losses.

[14] In such glasses, a distance from lenses to user's eyes is very important, wherein a fine distance in the range of l-2mm may cause a considerable difference in the corrected sight of the lenses.

[15] Further, nose pads and hooks directly contact user's nose and ears, and pulling force of the nose pads and the hooks apply pressure to the contact portions. Therefore, adjustment of the fine distance in the range of l-2mm may cause considerable difference in the intensity of such pressure and in the user's wearing comfort. Disclosure of Invention Technical Problem

[16] Therefore, the present invention is derived to resolve the above and any other disadvantages of the prior art.

[17] An object of the present invention is to provide order-made type glasses, which may be adjusted easily, especially, in the length by opticians or users regardless of characteristics of materials, from which the glasses is made, such as stiffness or handling- impossibility.

[18] Another object of the present invention is to provide glasses, in which fine distance adjustment may be possible in the length of temples so that sight improvement or wearing comfort improvement may be realized when a user wears the glasses. Technical Solution

[19] In order to achieve the above objects, glasses with length-adjustable temples according to the present invention comprises:

[20] a main body 1 including lenses 2;

[21] a pair of temples 10, each of which having a hook 12 curvedly formed at a rear end thereof for hanging on an ear of a wearer and a screw hole 11 formed at a front end thereof;

[22] a pair of guide body parts 20 with a predetermined length, each of which fitted onto each of the temples 10; [23] a pair of control screws 30 provided into the respective guide body parts 20, each of the control screws 30 having a screw part 31 in its rear part and a control part 32 in its front part, so that the screw part 31 can be coupled to the screw hole 11 of the temple 10 and the control part 32 can move the temple 10 to-and-fro;

[24] a pair of hinge elements 40, each of which mounted outside of a front end of the guide body part 20 to foldably connect the temple 10 to the main body 1; and

[25] a pair of rotation guide elements 50 for guiding the control screws 30 to rotate in right positions and move the temples 10 to-and-fro.

[26] The guide element 50 may include a rotation groove 34 formed along a periphery of the control part 32 of the control screw 30, a guide hole 21 formed in the guide body part 20 in a position corresponding to the rotation groove 34, and a guide protrusion 41 formed by protruding from the hinge element 40, so that the guide protrusion 41 is fitted into the rotation groove 34 via the guide hole 21, and the hinge element 40 is fixed on the guide body part 20, thus enabling the control screw 30 to rotate in right positions.

[27] Further, the guide element 50 may include a rotation groove 34 formed along a periphery of the control part 32 of the control screw 30, a screw hole 21 formed in the guide body part 20 in a position corresponding to the rotation groove 34, and a set screw 80 having a guide protrusion 81, so that the set screw 80 is coupled with the screw hole 21 and the guide protrusion 81 is fitted into the rotation groove 34, thus enabling the control screw 30 to rotate in right positions.

[28] Furthermore, the guide element 50 may include a rotation groove 34 formed along a periphery of the control part 32 of the control screw 30, and a support block 180 having a guide protrusion 181 formed in a corresponding shape to the rotation groove 34, so that the support block 180 is fixed on an internal surface of the guide body part 20 and the guide protrusion 181 is fitted into the rotation groove 34, thus enabling the control screw 30 to rotate in right positions and move the temple 10 to-and-fro.

[29] Therefore, the temples may be finely moved to-and-fro from the main body so that optimum sight and optimum wearing comfort may be obtained when a user wears the glasses.

[30] Further, the temples formed of expensive materials such as shape-memory materials and super elastic materials or the stiff materials, which are not deformed by heating, may be easily adjusted in the length by opticians for the user to wear the glasses in the optimum state.

[31] Therefore, the temples formed of the expensive materials may be spread widely and adjusted or repaired in the length by the opticians easily with economical profits.

Advantageous Effects [32] According to the present invention, it is possible to conveniently adjust the length of temples in the relatively simple structure so that optimum order-made glasses may be finished instantly by the fine distance control.

[33] Therefore, the market for the high grade glasses made of materials such as wooden materials, tortoise shells, horns, jewelry, the shape-memory materials and the super elastic materials, which are unlikely to be adjusted, may be activated and the high grade glasses formed of the stiff materials may be freely adjusted in the opticians.

[34] Further, according to the glasses with length-adjustable temples of the present invention, the sight improvement and the wearing comfort improvement may be noticeably realized by determining the pulling force of the nose pads and the hooks and finely adjusting the distance between the lenses and eyes in the range of l-2mm.

[35] Furthermore, according to the glasses with length-adjustable temples of the present invention, compatibility may be realized in the adjustment manner of the length of the temples, the user's inconvenience may be resolved via local area service network among the opticians, and the high grade glasses market may be activated so that users may create various atmospheres.

[41] Now, the glasses with length-adjustable temples according to the present invention will be described in more detail with reference to the accompanied drawings.

[42] Fig. 1 is a perspective view showing glasses according to a preferred embodiment of the present invention, wherein length-adjustable temples are mounted to a base frame of the glasses.

[43] Fig. 2 is a perspective view showing exploded principal parts of the glasses according to the preferred embodiment of the present invention, and Fig. 3 is a partially taken cross-sectional view showing principal parts of Fig. 2 in the assembled state. [44] Fig. 4 to Fig. 9 are respectively schematic views showing glasses according to further embodiments of the present invention. [45] According to the present invention, a main body of glasses has two lenses 2 and is mounted with temples 10 through hinge elements 40, which connect the temples to the main body 1 foldably. [46] The temples 10 according to the present invention are formed of various materials such as synthetic resin or nonferrous materials, wherein wooden materials, tortoise shells, horns, natural jewelry and noble metal materials, shape-memory materials and super elastic materials may be selected as the materials for the temples 10. [47] In general, the wooden materials, the tortoise shells, the horns, and the jewelry are not deformable in shape and length in spite of heating carried out by a heating machine equipped in an optician's shop. [48] These materials are cut by a cutter (now shown) by a certain length required for forming the temples 10 while the hinge elements 40 are mounted thereto, after measuring a distance from the main body 1 to hooks 12 of the temples 10 according to a face shape of a user who wears the glasses. [49] At this time, the cutter is to be a cutting tool such as a grinder or a power saw having the same function with the grinder. [50] The temples 10 are curvedly formed with hooks 12 at rear ends to be suspended on the ears of the user by a cutting or similar step in the manufacturing procedure thereof and insert-fixed with insert elements 19 at front ends, wherein the insert elements 19 are formed with screw holes 11. [51] Instead of inserting and fixing the insert elements 19 formed with the screw holes 11 into the temples 10, the screw holes 11 may be directly formed in the front sides of the temples 10 if the temples 10 are formed of the stiff materials. [52] Control screws 30, which are described below, are screw-coupled in the screw holes

11, and the hinge elements 40 are positioned between the temples 10 and the main body 1, wherein the hinge elements 40 are fitted into the rear parts of the main body 1 to be coupled with rear parts of the main body 1 and foldably connected thereto by hinge screws 70.

[53] The hinge screws 70 control fastening force of the temples 10 as hinges and simultaneously control the loose-fitting degree of the temples 10. [54] Guide body parts 20 are fitted outside the temples 10 to be couple with the temples

10, wherein the guide body parts 20 are formed in a hollow shape with a predetermined length. [55] Further, the control screws 30 have screw parts 31 at rear parts and control parts 32 at front parts, so as to be screw-coupled in the screw holes 11 of the temples 10. The control screws 30 are mounted in the guide body parts 20 for moving the temples 10 to-and-fro.

[56] Referring to Fig. 2 and Fig. 3, in order to control the control screws 30 finely by means of a driver or the like, the control screws 30 have the control parts 32 at the front parts, which are formed with manipulation grooves 33, and the screw parts 31 at the rear parts, so that the control screws 30 are screw-coupled in the screw holes 11 of the temples 10 and move the temples 10 to-and-fro in the screw direction at the time of fine adjustment.

[57] In order to rotate the control screws 30 in fixed positions in the guide body parts 20 so as to move the temples 10 to-and-fro, rotation guide elements 50 are provided.

[58] The rotation guide elements 50 are, as shown in Fig. 2 and Fig. 3, rotation grooves 34 formed outside the control parts 32 of the control screws, guide holes 21 formed in the guide body parts 20 at the corresponding positions to the rotation grooves 34 of the control screws 30, and guide protrusions 41 formed outside the hinge elements 40 to be fitted into the rotation grooves 34 of the control screws 30 via the guide holes 21 of the guide body parts 20.

[59] In other words, in the rotation guide elements 50, the guide protrusions 41 are protruded from the outside of the hinge elements 40, which are fixed outside the front parts of the guide body parts 20, so that the guide protrusions 41 are fitted and fixed into the rotation grooves 34 of the control parts 32 of the control screws 30, which are positioned in the guide holes 21 of the guide body parts 20.

[60] Therefore, as the control screws 30 are manipulated to rotate by the driver, the temples 10 screw-coupled with the screw parts 31 are moved to-and-fro for fine length adjustment while the control screws 30 rotate in the fixed position idly.

[61] That is, according to the function of the rotation guide elements 50, since the control screws 30 are kept in the coupled state between the rotation screws 34 of the control parts 32 and the guide protrusions 41 of the hinge elements 40, as a driver is fitted into the manipulation groove 33 and rotates the control screw 30, the control screw 30 does not move to-and-fro but the temple 10 screw-coupled with the screw part 31 of the control screw 30 becomes moving to-and-fro, thereby realizing the fine length adjustment of the temple 10.

[62] Fig. 4 and Fig. 5 show glasses according to another preferred embodiment of the present invention. Referring to Fig. 4 and Fig. 5, a set screw 80 is fixed outside the screw hole 21 of the guide body part 20 and has a guide protrusion 81 formed at an end. The guide protrusion 81 is fitted into the rotation groove 34 of the control part 32 of the control screw 30, which is positioned in the guide body part 20 via the screw hole 21 of the guide body part 20. [63] Therefore, in order to adjust the length of the temples 10, a driver is positioned in the manipulation groove 33 formed in the front surface of the control part 32 of the control screw 30 and rotates the control screw 30. Then, since the guide protrusion 81 of the set screw 80, serving as the rotation guide element 50, is in the coupled state in the rotation groove 34, the control screw 30 does not move to-and-fro but the temple 10 screw-coupled with the screw part 31 of the control screw 30 becomes moving to- and-fro, thereby realizing the fine length adjustment of the temple 10.

[64] Fig. 6 and Fig. 7 show glasses according to still another preferred embodiment of the present invention. Referring to Fig. 6 and Fig. 7, in the rotation guide element 50, the control part 32 of the control screw 30 is formed with a circular rotation groove 34 in an outer peripheral surface, and a support block 180 is fixed at a front side in the guide body part 20 and has a guide protrusion 181 in the corresponding shape to the rotation groove 34 to be engaged with each other.

[65] The support block 180 is positioned to an opened front end of the guide body part 40 and fixed thereto by welding and the like.

[66] Therefore, in order to adjust the length of the temples 10, a driver is positioned in the manipulation groove 33 formed in the front surface of the control part 32 of the control screw 30 and rotates the control screw 30.

[67] Then, since the guide protrusion 181 of the support block 180, serving as the rotation guide element 50, is in the coupled state in the rotation groove 34, the control screw 30 does not move to-and-fro but the temple 10 screw-coupled with the screw part 31 of the control screw 30 becomes moving to-and-fro, thereby realizing the fine length control of the temple 10.

[68] In the meantime, in the rotation guide elements 50, the rotation groove 34 of the control part 32 and the guide protrusion 181 of the support block 180 may be also formed in the opposite directions from each other, as shown in Fig. 8 and Fig. 9.

[69] In other words, a protrusion 35 is protruded from the outer periphery of the control part 32 of the control screw 30 while a guide groove 182 is formed in the support block 180 in the corresponding size to that of the protrusion part 35. In this case, if the control screw 30 is rotated by means of the driver and the like, the control screw 30 also rotates in the fixed position idly while inducing the fine length adjustment of the temples 10.

[70] According to the glasses with length-adjustable temples of the present invention as described hereinabove, if the control screw 30 is rotated in order to adjust the length of the temple, the control screw 30 rotates in the fixed position via the rotation guide element 50 and only the temples 10 moves finely to-and-fro in the lengthwise direction, so that the length of the temple may be set in the optimum state.
