[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is a high-fitting spectacle frame, and more specifically, when it is attached to the face, the elastic action of the front frame itself corrects the temple's temporal holding force to a soft and comfortable state. The present invention relates to a spectacle frame which has excellent fitting properties and can be bent in accordance with the above.

[0002]

[Prior art]

 In order to properly use eyeglasses, it is essential that the eyeglass frame fits comfortably and securely on the user's face without being easily displaced due to some vibration. Therefore, in the past, a spring-type hinge mechanism was constructed to elastically expand the temple further from the normally open position to the hinge part where the front frame and the ear hook temple are hingedly connected in a foldable manner. It was adopted, or the ear hook temple itself was made of an elastic material.

However, these utilize the elastic force that occurs only when the hinge or the ear hook temple is expanded further outward from the normally opened state and elastically deformed, so that the temporal region can be appropriately tightened to secure the spectacles. The spectacles front frame itself remained almost straight without being deformed. Therefore, when the conventional eyeglasses are worn on a Western-style face-type person whose nose or other face has a large protrusion in the center of the face, the gap between the face and the hinge portion of the eyeglass becomes large, and In order to wear it, the elastic holding force of the temples and the like must be increased by that amount, and as a result, this holding force gives discomfort to the temporal region and impairs the wearing comfort of the glasses.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above drawbacks of the conventional spectacle frame, and the elastic action of the front frame itself corrects the temple holding force of the temple to a soft and comfortable state. It is a first technical object to provide an eyeglass frame having excellent fitting properties that can be bent and deformed according to the shape of the face.

Further, in addition to the first technical problem, the present invention has a good appearance of the front frame of the spectacle frame, in particular, good appearance of the bridge portion from the front, and further, the inward bent state of the bridge portion and the elasticity. A second technical object is to provide a highly fitting spectacle frame that facilitates handling of spectacles by reliably restricting the spread within a predetermined angle.

[0006]

[Means for Solving the Problems]

 In order to solve the first technical problem, the present invention is a spectacle frame including a front frame F in which a pair of rims R and R are symmetrically connected by a bridge 1 and a brace bar 2. The bridge 1 is a connecting part 12 including piece parts 11 and 11 that are respectively joined to the inner sides of the pair of rims R and R that face each other, and companion piece parts 12a and 12a that are hinged to these piece parts 11 and 11. On the other hand, the brace bar 2 is made of elastic wire, and is joined to the pair of rims R and R while the front frame F is bent and biased inward at the piece parts 11 and 11. The elastic biasing force of the brace bar 2 is limited to a predetermined value by the bridge 1 of the hinge mechanism so that the front frame F can be elastically expanded from the inwardly bent state when it is mounted on the face. Do It adopted the technical means to say.

In order to solve the second technical problem, the present invention provides companion piece parts 12a, 12a to be connected to the piece parts 11, 11 on the eyepiece side of the connection part 12. At the same time, the bending parts 11a and 11a for maintaining the inner bending state of the front frame F at a predetermined angle and the expansion parts for restricting the elastic expansion of the front frame F within a predetermined angle are included in the respective piece parts 11 and 11. The means that the contact surfaces 11b and 11b are formed is adopted.

Furthermore, in order to solve the above-mentioned first and second technical problems, the present invention further includes a brace bar 2 in which the front frame F is bent inward at the piece parts 11 and 11 as necessary. We adopted a means to form the from a nickel-titanium superelastic alloy material.

[Embodiment of device]

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is a schematic plan view showing the free fitting state (solid line) of the high fitting spectacle frame according to the present embodiment and the elastically expanding state (dotted line) of the spectacle frame, and FIG. FIG. 3 is a partially enlarged perspective view showing a configuration of a main part, FIG. 3 is a partially enlarged perspective view showing a disassembled part of the same spectacle frame, and FIG. 4 is a partially enlarged plan view showing an inward bending state of a bridge 1 of the same spectacle frame. FIG. 5 is a partially enlarged plan view showing an elastically expanded state of the bridge 1 of the eyeglass frame.

In FIG. 1, what is designated by the symbol F is a characteristic of the spectacle frame of the present embodiment is a front frame that bends inward while exerting its head holding force. The front frame F is composed of a pair of rims R and R that holds a lens (not shown), and a bridge 1 and a brace bar 2 that symmetrically connect the pair of rims R and R. The front frame F is configured so as to maintain a state of being bent inward (face side) in the bridge 1 portion when it is not attached to the part (see the solid line in FIG. 1), and to the face part. When mounted, the front frame F 1 in the inwardly bent state can be expanded outward and elastically expanded (see the chain line in FIG. 1).

In FIG. 1, what is indicated by the symbol E is an end piece brazed to both ends of the front frame F, and what is indicated by the symbol T is a hinge H at the end of each end piece E. The ear hook temple hinged through the one, designated by the reference numeral N, is a nose pad which is brazed and joined to the inside of the rims R and R facing each other.

As shown in FIGS. 2 and 3, the bridge 1 that constitutes the front frame F is a two-piece piece piece component 11 that is brazed and joined to the opposite inner portions of the pair of rims R and R, respectively. .11, and a connecting part 12 having opposite piece parts 12a and 12a hinge-connected to these piece parts 11 and 11 by hinge screws 13 and 13, respectively. With this structure, the bridge 1 connects the pair of rims R and R symmetrically, and at the same time, the rims R and R are rotatable by the piece parts 11 and 11.

On the other hand, the brace bar 2 of the present embodiment is made of a nickel-titanium-based superelastic alloy material, and has a rod shape curved in the face direction. The curved braces bar 2 is joined to the upper chords of the rims R and R in a state where the front frame F is bent inward (face side) at the piece parts 11 and 11.

Therefore, the spectacle frame according to the present embodiment keeps the front frame F bent inward at the bridge 1 portion when not attached to the face portion (see the solid line in FIG. 1), The front frame F is elastically expanded against the elastic force of the brace bar 2 when the front frame F is attached to the portion (see the arrow in FIG. 1).

Therefore, when the spectacle frame is attached to the face, the front frame F itself exerts an elastic balance with the temple T · T at the bridge 1 portion due to the elasticity of the brace bar 2, and the temple T · T While performing T to exert a soft temporal holding force, the front frame F is bent in accordance with the shape of the face, so that even a person with a large undulation of the face can easily fit the face and the spectacle frame can be used. The whole will comfortably hold the temporal region. Therefore, there is no need to worry that a large amount of force concentrates on the temporal region and gives a feeling of oppression or discomfort, unlike the conventional product that exclusively uses the elasticity of the ear hanging temple.

In the eyeglass frame of the present embodiment, as shown in FIG. 1, the nose pad N / N is also provided on the inner side of the rim R / R facing each other. The holding force also acts on the nose pad N / N, and when the spectacles are worn, the nose pad N / N elastically sandwiches and holds the bridge of the nose. As a result, it is possible to more surely wear the spectacles, and it is possible to further disperse the elastic holding force of the brace bar 2 and the wearing comfort is further improved.

The spectacle frame of the present embodiment is further provided with means for restricting the inward bending angle and the elastic expansion angle of the front frame F. That is, as shown in FIG. 4 and FIG. 5, the bending contact surfaces 11a, 11a forming a predetermined angle (about 160 ° in this embodiment) with each other at the portions of the bridge parts 1 and 11 facing the connecting part 12 of the bridge parts 11. And the expanded surfaces 11b and 11b are formed.

As shown in FIG. 4, the bending contact surface 11 a formed at the tip on the opposite side to the rim of the piece component 11 abuts on the eyepiece side surface of the connecting component 12, whereby the front frame F is urged by the brace bar. The inner bent state of the bridge part 11 is maintained at a predetermined angle (about 20 ° in this embodiment), and conversely, at the time of mounting, as shown in FIG. 5, the expansion formed on the rim side of the piece part 11 is expanded. The maximum contact angle of the front frame F (about 0 ° in this embodiment) is restricted by the contact surface 11b contacting the eyepiece side surface of the connecting part 12.

As described above, in the spectacle frame of the present embodiment, the spectacles are easily handled by reliably controlling the inner bending and the elastic expansion angle of the front frame F. Furthermore, in the eyeglass frame of this embodiment, since the companion pieces 12a, 12a to be hingedly connected to the piece component 11 are provided on the eyepiece side of the connection component 12, the hinge connection portion is hidden by the connection component 12. Therefore, the hinge connecting portion does not spoil the appearance of the bridge 1 from the front.

The embodiment which is a specific example of the present invention is generally configured as described above, but the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. For example, in the above-described embodiment, the bridge component 11 is configured as a two-piece bridge component, but of course the invention is not limited to this, and the mating bridge portion 12 is You may make it a two-piece type.

[0021]

[Effect of the present invention]

 As described above with reference to the embodiments, in the high fitting spectacle frame according to the present invention, the front frame itself exerts an elastic temporal holding force when it is attached to the face portion, and has a facial shape. Since the spectacle frame is configured to be bent and deformed accordingly, the entire spectacle frame holds the head so as to comfortably hold the head. Unlike the conventional product, the elastic force of the front frame itself is positively used instead of the elastic force of the hinge parts and the outside of the ear hook temple. Even a Western-style face-type person with a large protruding portion and a large undulation on the face can be securely worn without causing discomfort in the temporal region.

In addition, the high fitting spectacle frame according to the present invention maintains the inner bending state of the front frame at a predetermined angle by a very simple structure in which the contact surface is formed on the bridge component piece of the elastically rotatable bridge. At the same time, the elastic expansion of the front frame is surely regulated within a predetermined angle, which makes it very easy to handle glasses. Moreover, since the hinge connecting portion of the bridge is configured so as not to be seen from the front, the hinge connecting portion does not spoil the appearance of the front frame.
