Description

[0001] The present invention relates to a combined structure of an eyeglass frame,

More particularly, the present invention relates to a joining structure for easily joining a frame, and more particularly, to a joining structure that can reduce the weight of a metal frame made of a metal material and secure a fitting of the lens, a firm fixing force, durability and safety at the same time To a coupling structure of a frame rim.

Usually, the rim constituting the spectacle frame is configured to be able to be completely fixed while surrounding the outer periphery of the lens.

The material constituting the spectacle frame is generally made of synthetic resin or metal. In the case of a synthetic resin material, the spectacle frame and the spectacle leg are respectively injected into the hinge formed by metal, or the hinge is integrally formed with the same synthetic resin So that the eyeglass frame and the hinge formed on the eyeglass leg can be connected by bolts to be rotatable.

When a spectacle frame is formed with a synthetic resin material, when a lens is inserted, a space in which a lens can be fitted is forcibly opened, and a lens is put on the rim by using the elasticity of a synthetic resin material .

However, when the spectacle frame is made of a metal material other than a synthetic resin, it is formed in one side of the gaze portion or the adjacent portion of the rim, and the incised portion is coupled to the upper and lower portions using a separate fixing member after inserting the lens Finally, the spectacle frame is constructed so that it can be completely fixed around the lens.

When the above-mentioned spectacle frame is made of a synthetic resin material, there is a problem that the lens is detached from the rim even when the spectacle frame is slightly bent. In addition, the spectacle frame is bent or even damaged due to frequent deformation There are often problems.

Due to such a problem, a large number of eyeglass frames made of a metal material other than a synthetic resin material have been manufactured and used. However, the eyeglass frame made of a metal material is fixed on the upper and lower portions by using a fixing member, .

However, in the case of the metal frame, the casters are generally cut, and the respective coupling grooves are formed on the incised one side, and the upper and lower parts are sequentially coupled to the coupling groove by using the fixing member.

However, since the force that is applied to the joint portion in the combined state is strong, it is necessary to process such that the pitch of the frame (thread) is formed so as to have a larger force than this force. It takes time to lower the productivity.

In addition, when the fixing member is loosened due to a high pitch (screw thread) to replace the lens of the spectacle frame, it takes a long time to replace the lens. In addition, If the pitch formed in the rim is broken, the rim may widen and the lens may be detached from the spectacle frame.

Conventionally, there have been proposed a metal thin plate type spectacle frame having an improved assembling structure, a registered trademark 20-0472408, a spectacle lens frame having improved spectacle lens coupling structure, and a spectacle lens having a spectacle lens Synthetic resin eyeglass frames with improved fixing structure ', public utility model 20-2010-0005650' lens hanger-integrated lens fastener with assembly of spectacle lens', registered patent 10-1059754 'coupling structure of glasses', registered patent 10-1359793 Although the above-described prior art discloses a coupling structure of a spectacle frame, the above-described problem is brought about.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an eyeglass frame structure in which the thickness of the spectacle frame is 1.5 to 3.0 mm so that the overall weight can be reduced and the groove is formed on one side of the upper incision rim, Wherein the insertion groove is formed at one side of the lower incision rim and is formed to be inserted into the groove, and is fitted into the fitting groove by using a binding member having a screw thread formed on the outer periphery thereof, The coupling member can be made to have a structure in which the coupling member can be held in a horizontal direction rather than in a vertical direction so that the coupling member can receive the force as a whole to secure the durability and the firm fixing force of the lens. It is a technical problem to focus on providing the structure.

In order to accomplish the above object, the present invention provides a joining structure of a metal frame, wherein the rim is formed as an upper incision rim (110) and a lower incision rim (120) A groove portion 111 is formed on one side of the lower cutting rib 110 and a fitting groove 113 connected to the groove portion 111 is formed on the other side of the lower cutting rib 120. On one side of the lower cutting rib 120, The insertion groove 121 is formed in the insertion groove 121 and is inserted into the groove 111 by using a coupling member b having a thread formed on the outer periphery of the insertion groove 121, And is coupled to the coupling groove (123).

According to the joining structure of the eyeglass frame easy to be combined according to the present invention, the thickness of the metal frame is made to be 1.5 to 3.0 mm so as to make the weight lighter, and the incised rim is welded The upper incision rim is not threaded, but only the lower incision rim is formed with threads, so that the lower incision rim can be connected to the lower incision rim by the binding member, and can be fixed to the upper incision rim. The joining direction of the members is bound to the front and rear surfaces (horizontal) rather than the upper and lower portions (vertical) of the spectacle frame, so that a firm fixing force can be ensured even with a minimum number of threads.

Generally, in the case of a metal frame, it is generally necessary to cut the casar portion, and each of the engagement grooves is formed on one side of the incised portion, and then the upper and lower portions of the rim are combined And then integrally joining the incised portions through constituent welding.

If the incised portion is welded, the welded portion is not protruded because of the nature of the welding, so that the wearer may be scratched or injured.

However, in the state where the rim is coupled by the coupling member, it is necessary to process the frame so that the pitch (thread) of the frame is formed so as to prevent the joined portion from spreading. It takes a lot of time to process the pitch (thread) In addition, in order to process a large number of pitches, the thickness of the metal frame is generally large and the weight is heavy.

Further, it takes a long time to replace the lens of the spectacle frame by loosening the binding member due to a high pitch (screw thread), and even when the fisheye formed on the outer periphery of the fixing member due to the opening force of the gaze portion, If the pitch formed in the rim is broken, the rim may widen and the lens may be detached from the spectacle frame.

Accordingly, the present invention can reduce the weight of the frame made of a metal material so that the rim can be engaged at the side (horizontal direction) rather than at the upper and lower parts when the rim is engaged by the fitting of the lens and the binding member, thereby securing a firm fixing force and durability The present invention also provides a joining structure of a spectacle frame which is easy to combine so as to prevent visual phenomenon and scratching due to lack of protruding parts such as welded parts.

The engaging groove 123 is engaged with the engaging groove 113,

The coupling structure of the spectacle frame according to the present invention, which is combined with the above structure, will be described in more detail.

As shown in FIG. 3 or 4, the rim 100 is formed to have a thickness of 1.5 mm to 3.0 mm and is formed in an incision form with an upper incision rim 110 and a lower incision rim 120, The rim 110 is formed with a groove 111 formed by a conventional cutting tool and an upper fitting groove 115 connected to the groove 111 is formed at one side of the upper incision rim 110 And an insertion groove 113 in which a lower fitting groove 117 connected to the groove 111 is formed is inserted into the upper incision rim 110 at a predetermined depth.

That is, in the case of the upper fitting groove 115, the lower fitting groove 117 is formed so as to be connected to the groove 111 and is not penetrated in the lower fitting groove 117 but is formed inside the upper cutting groove 110, To be connected.

An insertion portion 121 is formed at one side of the lower incision rim 120 and has an engagement groove 123 formed with a thread 125 on the inner side thereof so as to be inserted into the groove portion 111, And is formed to be slightly smaller than the inner side of the groove 111 so as to be inserted into the groove 111.

5 to 6, the insertion portion 121 of the lower incision rim 120 is inserted into the groove portion 111 of the upper incision rim 110 and is then bound to the binding member b A thread formed on the outer circumference of the coupling member b is formed in the coupling groove 123 in the inner side of the coupling groove 123 in the upper fitting groove 115, And a lower portion of the coupling member b is inserted into the lower fitting groove 117 to be engaged and fixed.

That is, the head portion and the lower portion of the binding member (b) are engaged with the inner side of the upper and lower fitting grooves (115, 117) after the binding member (b) The threaded portion 125 is coupled with the coupling member b so that the coupling member b is horizontal and receives a force so that the upper and lower incision rims 110 and 120 are not warped even if a warping phenomenon occurs.

Conventionally, in order to prevent the lens from being separated from the lens of the metal frame after fixing the lens, a cut-out groove is formed in the upper and lower portions (vertical direction) of the cut rim to insert a binding member such as a bolt into the groove portion Respectively.

In addition, in order to secure a firm fixing force of a widened portion due to the nature of a metal material, a force to tighten the widening force must be strong, so that not only a thread (pitch) is formed inside the groove portion but also a thread The length of the coupling member coupled with the thread must be long, and the metal frame of the metal material must be thick as a whole.

However, as described above, the joint structure of the present invention is formed such that the thickness of the rim 100 is 1.5 to 3.0 mm, and the weight of the metal frame made of a metal material is lightened so as to feel a feeling of fit similar to the weight of the synthetic resin material But it is possible to have a firm fixing force.

5 to 6, in which the coupling structure of the upper incision rim 110 and the lower incision rim 120 is coupled to each other, When the insertion portion 121 of the lower incision rim 120 is inserted into the groove portion 111 of the upper incision rim 110 and then engaged using the binding member b, So that the overall thickness of the spectacle frame can be made thin and the binding member b can be engaged only with the coupling groove 123 of the lower incision rim 120 and prevented from being deviated to the outside, Is a ring-shaped structure that can be simply fitted into the upper and lower fitting grooves 115, 117 of the upper incision rim 110 and can be fixed by abutting against the inner side surface.

In other words, it is possible to secure a stronger fixing force and durability even without machining a lot of threads (pitch) by forming the thickness of the spectacle frame thick as in the prior art, and to secure the fixing force and durability by joining the binding member (b) So that the weight can be lightened.

When the groove portion 10 of the upper incision rim 110 is machined, the insertion portion 121 of the lower incision rim 120 is inserted, which is not completely inserted. Therefore, It is possible to shorten the working time and to insert it easily.

In other words, the upper incision rim 110 and the lower incision rim 120 of the present invention are engaged with the lower incision rim 120 so that the binding member b functions as a fins but is not separated, The member b is fixed in abutment with the inside of the upper and lower fitting grooves 115 and 117 so that the binding member b receives uniformly the force to be widened as a whole to secure a firm fixing force and durability .

In addition, when the binding member (b) is tied, the head portion is protruded or inserted at the same height as the surface of the rim (100) or very fine, thereby preventing the problem of scratching against the wearer's face when wearing glasses, It will be possible.
