DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure used for mounting a pad or a small accessory component on an eyeglass frame.

[0002]

2. Description of the Related Art A conventional spectacle frame pad is molded integrally with a spectacle frame body, or a pad box in which a pad is fixed to a tip of a pad foot brazed to the spectacle frame with a screw is movably fitted. It is attached to the eyeglass frame body by such a structure. Brazing and screwing structures have also been used for attaching small accessory parts for decoration.

[0003]

However, when the small parts are integrated with the spectacle frame body by brazing or integral molding, it becomes impossible to replace the small parts.
When the small component is a pad, there arises a problem that a comfortable fit with the face cannot be obtained.

[0004] Further, in the case of the screwed structure, there is a problem that looseness of the screw causes looseness, and the connection between the small component and the spectacle frame main body is disconnected due to the falling off of the screw. In addition, there is a problem that a time-consuming step of screwing is involved in assembling the eyeglass frame, and in this screwing, parts may be damaged by the tip of the driver.

Accordingly, the present invention is capable of semi-permanently holding small parts such as pads and decorative parts to be mounted on the eyeglass frame main body in a proper state without causing backlash or falling off of a connecting part, and assembling work. It is an object of the present invention to obtain a small component mounting structure that can mount these small components without damaging the components in a short time.

[0006]

The mounting structure for small parts in the eyeglass frame according to the present invention includes a pair of a shaft member 9 and a box member 3, and the shaft member 9 has a bulging portion 10 and a neck portion 11 at the tip. The bulging portion 10 and / or the neck portion 11 have a flat shape in a direction perpendicular to the axis thereof, and the box member 3 is inserted into the chamber 4 for accommodating the bulging portion 10 and the opening 5 through which the neck portion 11 passes. The chamber 4 and the opening 5 are provided with a slit 6.
And the neck 11 has a cross-sectional area in which it can float,
The chamber 4 and / or the opening 5 have a flat cross section in a direction perpendicular to the axis of the shaft member 9 inserted therein, so that the rotation angle and the swing angle of the shaft member 9 in the box member 3 are regulated, The insertion slit 6 has a passage area through which the shaft member 9 can pass by being forcibly pushed, and one of the shaft member 9 and the box member 3 is attached to the spectacle frame main body 1 and the other is attached to the eyeglass frame body 1. It is characterized in that it is integrated with each component 8.

[0007]

The shaft member 9 and the box member 3 are connected by pushing the shaft member 9 into the box member 3 through the insertion slit 6 of the box member 3. At this time, the bulged portion 10 of the shaft member is housed in the chamber 4 of the box member, and the neck portion 11 penetrates the opening 5 and protrudes out of the box member 3. Thus, the member fixed to the box member 3 and the member fixed to the tip of the shaft member 9 are joined. Since the shaft member 9 can move freely in the box member 3 and its movement limit is restricted, if the structure of the present invention is used as a pad mounting structure, the pad 8 can be freely moved within a certain range of the pad 8. Since the movement is ensured, a proper fit of the pad 8 to the face is ensured. Further, if the box member 3 or the shaft member 9 of the present invention is made of resin and is formed integrally with the pad 8, the manufacturing process of the pad is simplified, and the shaft member 9 is formed.
The pad 8 can be mounted on the spectacle frame main body 1 by a simple operation of pushing the pad 8 through the insertion slit 6 into the box member 3, so that the assembling work of the pad becomes extremely easy, and there is no problem in replacing the pad.

Further, even when the shaft member 9 is made of metal, the bulging portion 10 can be formed by head punching, so that the brazing step is not required, and the bulging portion 10 falls off due to the wax separation. Can be prevented.

[0009]

1 and 2 show a structure in which a pad 8 is mounted on an eyeglass frame body 1 according to the structure of the present invention. A box member 3 is integrated with the spectacle frame body 1 via box legs 2 brazed thereto. As shown in FIG. 3, the box member 3 has a chamber 4 therein, and is opened on the opposite surface of the box foot 2 with an opening 5 having an area smaller than the cross-sectional area of the chamber 4. The chamber 4 and the opening 5 have a rectangular cross section or opening surface, and have an insertion slit 6 at one end on the narrow side for inserting a shaft member 9 described later into the chamber 4 and the opening 5. The insertion slit 6 can be provided on both sides of the chamber 4 and the opening 5 as shown by imaginary lines in FIG.

The pad 8 is a resin molded product integral with a shaft member 9 serving as a pad mandrel. The shaft member 9 has a bulged portion 10 housed in the chamber 4 of the box member 3 and a neck portion 11 penetrating the opening 5. And As the shape of the shaft member 9, various shapes as shown in FIGS. 4 to 7 can be adopted. The shapes shown in FIGS.
Are both flat in the direction perpendicular to the axis, that is, the bulging portion 10 and the neck 1 when the shaft member 9 is viewed from one of its sides.
The widths h and w of 1 are narrower than the widths H and W of the bulging portion 10 and the neck portion 11 when viewed from a direction orthogonal to this. The insertion slit 6 of the box member 3 has an area slightly smaller than the shape of the shaft member 9 on the narrow side, and the shaft member 9 passes through the insertion slit 6 due to the elastic deformation of the shaft member 9 and the box member 3. Then, it is stored inside the box member 3.

The chamber 4 and the opening 5 of the box member 3 are shown in FIG.
2, it has a larger cross section than the bulge 10 and neck 11 of the inserted shaft member, so that the box member 3
There is a play space 12 between the shaft member 9 and the shaft member 9 inserted therein.
The box member 3, that is, the eyeglass frame body 1 integrated with the box member 3, can freely swing and rotate in this play space. However, the swelling portion 10 and the neck portion 11 of the shaft member 9 are flat, and the chamber 4 and the opening 5 of the box member are also rectangular (flat square). The rotation of the shaft member within the box member 3 is limited to a certain angle range, and the shaft member is restrained while the neck portion 11 of the shaft member passes through the opening 5 of the box member. 9 is also restricted to a certain angle range. In this case, as shown in FIG. 5, for example, by using a shaft member having a thinned tip end side of the bulging portion 10, the shaft member 9 has a larger allowable swing angle within a box member having the same shape. By changing the shapes of the bulging portion 10 and the neck portion 9, the rotation and swing range of the shaft member 9 with respect to the box member having the same chamber 4 and the opening 5 can be variously changed.

The shaft member 9 shown in FIG.
Is spherical, and only the neck 11 has a flat shape in the direction perpendicular to the axis. The rotation of the shaft member 9 having such a shape is restricted by the dimensional relationship between the neck 11 and the opening 5 of the box member.

The shaft member 9 pushed into the box member 3 through the insertion slit 6 does not fall out of the box member 3 because the bulging portion 10 does not pass through the opening 5, and the shaft member 9 is forced. Insertion slit 6
, The shaft member 9 does not fall out through the insertion slit 6 in a normal use state. on the other hand,
When replacement of the pad 8 or the like is necessary, the shaft member 9 can be removed from the box member 3 through the insertion slit 6 by applying force. In the embodiment shown in FIG.
The inner side surface of the side in the longitudinal direction is an inclined surface that opens outward, so that the swing of the shaft member 9 in the box member 3 is not restricted by the interference between the inner side surface of the opening 5 and the neck 11. Has become.

[0014]

According to the structure of the present invention described above,
Attachment of small parts such as pads to the spectacle frame can be performed with a simple operation of pushing the shaft member into the box member, which can significantly reduce the number of assembly steps, and at the time of assembling the parts by the tip of the driver etc. There is no risk of damage. When the structure of the present invention is used as a pad mounting structure, the pad and the pad mandrel etc. are formed as an integral resin molded product, thereby simplifying both production and assembly of parts, and Since the structure can swing and rotate within a certain range, the fit of the pad to the face is not impaired. Further, in the structure according to the present invention, since there is no portion to be fixed by the screw, there is no problem of loosening or falling off of the screw, and there is an effect that the stable mounting state of the small component can be held semipermanently.
