Description

The present invention relates to a nose pad support structure for an eyeglass frame, and more particularly to a nose pad support structure in which a support member for supporting the nose pad is attached to a bridge of the eyeglass frame. Regarding the structure.

[Conventional technology]

As is well known, the spectacle frame is a pair of lens frames and a pair of temples that are rotatably connected via a hinge, and in the vicinity of the mutual connecting portion of the pair of lens frames, both side portions of the nose. Is provided with a pair of nose pads that abut and lock with. As a specific example of the structure for supporting the pair of nose pads on the eyeglass frame, for example,
According to 55-105412 (see FIG. 5), a pair of ball frames 5
A structure is disclosed in which a pair of nose pads 53, 53 is attached to a bridge 51 connecting 0, 50 via a support member 52. The detailed structure of the support member 52 is, as shown in FIG. 6, an engaging member 54 arranged at the upper end and extending in the left-right direction,
An elastic body 55 that extends downward from both ends of the engaging body 54, has a nose pad 53 attached to the lower end thereof, and has a first bent portion 55a and a second bent portion 55b in the middle thereof, and a first bent portion of the elastic body 55. Five
It is composed of a locking projection 56 attached near 5a. Then, as shown in FIG. 5, the engaging body 54 of the support member 52 is engaged with the upper edge of the bridge 51 of the spectacle frame, and
The locking projections 56 of the support member 52 are embedded in both side portions of the bridge 51.

[Problems to be solved by the device]

However, in the conventional example disclosed in the above publication, the support member 52
Since the engaging body 54 of the above is configured to be engaged with the upper edge of the bridge 51, the elastic body from the engaging body 54 to the nose pad 53
There is a problem in that the total length of 55 becomes long, and the amount of material is increased and the manufacturing cost is soared. Further, in this conventional example, the locking protrusion 56 near the first bent portion 55a of the elastic body 55 is used.
Since the is embedded in the bridge 51 and fixedly supported, it is the second part of the elastic body 55 that contributes to the elastic support action of the nose pad 53.
Since it is limited to the vicinity of the bent portion 55b, there is a problem that the elasticity cannot be sufficiently secured. Further, in this conventional example, the engagement body 54 of the support member 52 covers the upper edge of the bridge 51 from the front surface side to the rear surface side.
Will appear as an appearance on the front surface and the top surface of the bridge 51, and this will also cause a defect that the aesthetic appearance is impaired.

In view of this, the present invention aims to reduce the total length of the supporting member as much as possible to reduce the amount of material, improve the elasticity of the supporting member, and improve the appearance of the periphery of the bridge. This was done as a technical issue.

[Means for Solving the Problems]

As a concrete means for achieving the above technical problem, a bridge that connects a pair of lens frames and a support member that supports a pair of nose pads is provided, and the support member is attached to the bridge. In the spectacle frame, the support member is embedded in the bridge with the front end being an extension extending in the left-right direction, and the rear end projects rearward by a predetermined dimension from the rear surface of the bridge; A base body which is continuously provided at the rear end and extends in the left-right direction along the lower edge of the bridge and has a slight gap between the bridge and the rear surface of the bridge, and extends downward from both ends of the base body to the lower end. The nose pad is attached to the nose pad, and the elastic body is bent in opposite directions at two points along the nose pad and has a stepped shape, and these are integrally formed of the same material and the same thickness width.

[Action]

According to the above means, the embedded body of the support member has only its rear end protruding to the rear of the bridge of the spectacle frame, and the other portions are completely embedded in the bridge. Does not appear as an appearance, therefore, the appearance around the bridge is improved, and at the front end of this buried body, an extension portion extending in the left-right direction is formed, so that the buried body is not inside the bridge. Since it is firmly embedded, it can be reliably prevented from being pulled out. Further, since the base body connected to the rear end of the embedded body extends in the left-right direction along the lower edge of the bridge, the dimension from the base body to the nose pad is shortened as much as possible, The length of the member and the amount of the material can be reduced. Further, since the base body has a slight gap between it and the rear surface of the bridge and the elastic bodies extend downward from both ends of the base body, only the embedded body is fixed to the bridge. In addition, since the elastic body is formed with the bent portions at two places, the elasticity and the impact relaxation property with respect to the nose pad are significantly improved.

Moreover, since the embedded body that is the upper end member of the support member is attached to the bridge, and the embedded body of the support member, the base body, and the elastic body are integrally formed of the same material and the same thickness width material, the external force applied to the support member is increased. Can be substantially evenly distributed over the entire support member, so that even if the nose is strongly pressed against the nose pad, the reaction force at this time can be flexibly absorbed by the entire support member. Further, since the embedded body is embedded in the bridge with the front end extending in the left-right direction, it is embedded in the bridge in a relatively wide range even if external force is applied to the support member from either the horizontal direction or the vertical direction. Can be dispersed in.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1 and FIG. 2, the spectacle frame 1 is one in which a pair of lens frames 2, 2 rotatably holds a temple 4, 4 via hinge fittings 3, 3. The pair of ball frames 2 and 2 are in a state of being connected to each other via a lower first bridge 5 and an upper second bridge 6. A support member 7 is provided on the first bridge 5.
Is attached, and a pair of nose pads 11, 11 is equipped at the lower end of the support member 7.

As shown in FIG. 3, the support member 7 is provided with two embedded bodies 8 and 8 each having a front end extending in the left-right direction and having a T shape, and a rear end of the embedded bodies 8 and 8. A base body 9 extending in the left-right direction along the lower edge of the first bridge 5, and a resilient body extending downward from both ends of the base body 9 and having a first bent portion 10a and a second bent portion 10b formed in the middle thereof. 10 and each of these bodies 8, 9 and 10 are integrally formed.

Then, as shown in FIG. 4, the front ends of the buried bodies 8 and 8 are buried in the first bridge 5 and the rear ends thereof are first.
The base 9 projects rearward from the rear surface 5a of the bridge 5 by a predetermined dimension, and the base 9 is arranged with a slight gap X between the rear surface 5a of the first bridge 5 and the rear surface 5a.

Incidentally, the number of the embedded bodies 8 and 8 is not limited to two as described above, and may be one or three or more.

According to the above configuration, the embedded bodies 8, 8 of the support member 7 are in a state in which only the rear end portion thereof projects rearward from the rear surface 5a of the first bridge 5, and the other portions are embedded in the first bridge 5. Therefore, the buried bodies 8 are not exposed on the front surface and the upper surface of the first bridge 5, so that the appearance of the periphery of the first bridge 5 is improved. Further, since the embedded bodies 8 and 8 are embedded in the first bridge 5 when the eyeglass frame 1 is molded, and the front end thereof has an extending portion extending in the left-right direction, the embedded body 8 is embedded. Even if a backward force is applied to the bodies 8 and 8, there is no danger of pulling out.

On the other hand, since the base body 9 of the support member 7 extends in the left-right direction along the lower edge of the first bridge 5 (see FIG. 1), the dimension from the base body 9 to the nose pads 11, 11 is extremely short. Therefore, the entire length of the elastic bodies 10,10 and thus the entire length of the support member 7 are shortened as much as possible. In addition to the fact that the base body 9 has a slight gap with the rear surface 5a of the first bridge 5,
Since the elastic body 10 extending downward from both ends of the base body 9 is formed with the first and second bent portions 10a and 10b, the embedded body 8, 8 and the base body 9 are connected to each other, and the first bent portion 10a. The three positions of the second bent portion 10b contribute to the improvement of elasticity, and if the support member 7 is made of the same material and the material of the same thickness width, the elasticity is significantly larger than the conventional one. It will be improved.

Moreover, the embedded body 8 which is the upper end member of the support member 7 is attached to the bridge 5, and the embedded body 8 of the support member 7, the base body 9 and the elastic body 10 are integrally formed of the same material and the same thickness width material. By this, the external force applied to the support member 7 can be dispersed substantially evenly over the entire support member 7, so that even if the nose is strongly pressed against the nose pad 11, the reaction force at this time is not
Can be flexibly absorbed effectively. Therefore, the load applied to the embedded body 8 of the support member 7 is reduced, the embedded body 8 is prevented from falling out of the bridge 5, and the vicinity of the embedded body 8 of the support member 7 is repeatedly subjected to concentrated stress and is fractured. It can be prevented.

Further, since the embedded body 8 is embedded in the bridge 5 with its front end extending in the left-right direction, it is embedded in the bridge 5 regardless of the external force applied to the support member 7 from the left-right direction or the vertical direction. Can be distributed over a relatively wide range. Therefore, it is possible to form the bridge 5 with a material that is relatively brittle for decorative reasons, and the degree of freedom in design can be greatly expanded.

Further, in the support member 7, the embedded body 8 is embedded in the rear surface 5a of the brid 5, and the base body 9 is connected to the rear end of the embedded body 8 to form the base body 9
Since the elastic members 10 extending downward are formed at both ends of the support member 7, the support member 7 is not exposed to the surface side of the bridge 5, and the appearance is excellent. In addition, the support member 7
Since the gap X is provided between the base body 9 and the surface 5a of the bridge 5, high designability can be achieved.

In the above embodiment, the present invention is applied to the spectacle frame 1 in which the bridge connecting the pair of lens frames 2,2 is the two bridges 5,6. It goes without saying that the present invention can be similarly applied to an eyeglass frame in which a pair of lens frames are connected by a bridge.

[Effect of device]

As described above, according to the nose pad support structure for the spectacle frame according to the present invention, the embedded body of the support member is embedded without being exposed on the front surface and the upper surface of the bridge, so that the appearance around the bridge is improved. In addition, there is an advantage that the pulling out can be reliably prevented by the action of the extending portion formed at the front end of the embedded body. Further, since the base body of the support member extends in the left-right direction along the lower edge of the bridge, compared to the case where the base body (engagement body) is engaged with the upper edge of the bridge as in the conventional case, the base body of the support member is nose pad. The advantage is that the overall length of the process can be shortened, the amount of material can be reduced, and the manufacturing cost can be reduced. Further, since the base body of the support member has a slight gap between it and the rear surface of the bridge, only the embedded body is fixed to the bridge, and the elastic body extending downward from both ends of the base body is 2 Since the bent part is formed in the place,
The elasticity of the supporting member as a whole is increased, and the usability is improved.

Moreover, since the embedded body that is the upper end portion of the support member is attached to the bridge, and the embedded body of the support member, the base body, and the elastic body are integrally formed of the same material and the same thickness width, the external force applied to the support member is increased. Can be substantially evenly distributed over the entire support member, so that even if the nose is strongly pressed against the nose pad, the reaction force at this time can be flexibly absorbed by the entire support member. Therefore, it is possible to reduce a load applied to the embedded body of the support member, prevent the embedded body of the support member from falling out of the bridge, and prevent the vicinity of the embedded body of the support member from being repeatedly subjected to concentrated stress.

Further, since the embedded body is embedded in the bridge with the front end extending in the left-right direction, it is embedded in the bridge in a relatively wide range even if external force is applied to the support member from either the horizontal direction or the vertical direction. Can be dispersed in.
For this reason, the bridge can be formed of a material that is relatively brittle for decoration reasons, and the degree of freedom in design can be greatly expanded.

In addition, the support member, the embedded body is embedded in the rear surface of the bridge,
Since the base body is connected to the rear end of the embedded body and the elastic body extending downward is formed at both ends of the base body, the supporting member is not exposed to the surface side of the bridge and the appearance is excellent. ing. In addition, since a gap is provided between the base of the support member and the surface of the bridge, high designability can be achieved.
