2. Description of the Related Art As an example of a conventional nose pad in which a nose pad can be connected to a box-shaped connecting body provided at one end of a connecting arm by a one-touch method, an actual open shovel is 61-1.
A structure disclosed in Japanese Patent Publication No. 09426 has been proposed.

In FIGS. 8 to 9, the nose pad a has a pair of connecting pieces c, c projectingly provided on the back surface of the pad main body b so as to be opposed to each other with an interval, and engaging projections are provided on the outer surfaces of the respective connecting pieces. It had a configuration in which the parts d, d were provided in a protruding manner. When connecting the nose pad to the connecting body g of the connecting member h in which the box-like connecting body g is fixed to the tip of the connecting arm e, as shown in FIG. As described above, both connecting pieces c, c are elastically deformed inward and pushed into the space i of the connecting body g, and the engaging protrusions d, d are provided on the opposite side surface portions of the connecting body g. The nose pad a is connected to the connecting body g by fitting it into the locking holes j, j.

[0004]

In the nose pad having the above-mentioned structure, since the independent connecting pieces are provided on the back surface of the pad body so as to be opposed to each other with a space therebetween, the connecting pieces are connected to each other. When pushed into the space, the connecting piece can be elastically deformed inwardly, so that there is an advantage that the nose pad can be easily attached to the connecting body. In this way, both connecting pieces can be freely deformed independently. This also had the following disadvantages.

Problems in Holding Nose Pad to Adjust Bending Condition of Connecting Arm As shown in FIG. 10, the connecting member is brazed to a lens frame, and the connecting body f of the connecting member g is attached to the connecting body f. In the eyeglasses to which the nose pad a is attached, the pad body b may be grasped to adjust the bending condition of the connecting arm according to the procedure.
As shown in FIG. 11, the adjustment is performed by twisting the nose pad (arrow f) while the movement of the connecting piece is restricted by the inner surface portion k of the hollow space i of the box-shaped body (arrow f). The piece c will undergo torsional deformation. As a result, the base part m
In the connecting piece c which is only integrated with the pad body b only in (FIG. 8), the base end portion k is bent into an elastically unrecoverable state due to the torsional deformation received by the connecting piece c, Alternatively, when the connecting piece is made of a hard resin, there is a risk of breaking at the base end portion. The damaged nose pad can no longer function normally as a nose pad.

Problems when Replacing Nose Pad Focusing on the advantage that the nose pad can be easily attached to the box-like body by one-touch operation, for example, by preparing several kinds of nose pads of different colors There is a demand to change the nose pad and enjoy fashion. When the nose pad is intended for such a purpose, it is necessary that the wearer, who is an amateur with respect to eyeglasses, can easily exchange the nose pad. However, when the structure of the conventional nose pad described above is used,
If it is forcibly twisted when removing the nose pad, as described above, the connecting piece may be irreversibly twisted, deformed, or broken, and the damaged nose pad may be damaged. There was a problem that it could not be reused. For this reason, the above-mentioned conventional nose pad has not been able to meet the demand.

An object of the present invention is to provide a nose pad for spectacles which can solve such problems.

[0008]

To solve the above problems, the present invention employs the following means. That is, in the nose pad for eyeglasses according to the present invention, a resin-made connecting tube portion having a tubular shape (square tube shape, elliptical shape, etc.) with an open tip is provided on the back surface of the pad body, and An engaging projection that is fitted to a locking hole provided in the facing portion of the connecting body that has a space for pushing in the connecting tubular portion is provided at the facing portion of the outer peripheral surface of the tubular portion. To do.

It is preferable that the connecting tube portion is formed in a rectangular tube shape having a rectangular cross section or a square cross section. Further, in the case where the connecting cylinder portion is formed into a rectangular tube shape in this manner, among the four side surface portions of the connecting cylinder portion, the side surface portion on which the engaging projection is projected is formed to be thinner than the other side surface portions. Good to do. Further, it is also preferable that, out of the four side surface portions of the connecting tubular portion, both side surface portions on which the engaging protrusions are not provided are curved so as to project outward.

Further, in the nose pad for each spectacle described above,
A solid substance containing a fragrance is housed in the connecting cylinder so that the solid does not protrude from the tip of the connecting cylinder even when the connecting cylinder is deformed when the connecting cylinder is pushed into the space of the connecting body. Is preferred.

[0011]

However, in order to connect the nose pad constructed as described above to the connecting body provided at the tip of the connecting arm and provided with the engaging holes in the left and right facing portions, the connecting tubular portion is engaged with the connecting cylinder portion. Align the abutment with the left and right locking holes and push it into the empty space of the connector. Due to this pushing, the opposing portion where the engaging projection is provided is elastically deformed inward, and after the engaging projection and the locking hole are fitted together, the connecting tubular portion is elastically restored to the initial state. Restore.

The inward elastic deformation of the facing portion is caused when the side surface portion on which the engaging projection is projected is formed thinly.
More easily done. Further, when both side surface portions not provided with the engaging protrusions are curved outwardly, the both side surface portions can be deformed more easily, so that the elastic deformation can be facilitated. .

When the nose pad connected in this way is replaced, the connecting cylinder portion has a cylindrical shape, that is, the edges of the opposite ends of the opposing portions formed by the engaging projections are connected to each other. Since the connecting cylinder has a strong structure against twisting, even if the nose pad is twisted and removed, the nose pad is not deformed excessively and the nose is not deformed. The pad can be removed. Further, when the connecting arm is made of a relatively soft material, even if the bending condition of the connecting arm is adjusted by gripping the nose pad, the connecting cylinder portion is not unduly deformed.

When a solid substance containing a fragrance is contained in the connecting cylinder portion, it is preferable that the aroma is diffused from the solid substance.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, the nose pad 1 according to the present invention is
The whole is integrally formed of a synthetic resin, for example, nylon, and on the back surface of the pad body 2, a connecting cylinder portion 3 having a rectangular cross-section with an open tip is formed in a protruding manner. The facing portions (side surface portions) 4 and 4 are formed thinner than the other side surface portions 5 and 5. Further, on the outer surfaces of the side surface portions 5 and 5, engaging projections 6 and 6 are provided so as to bulge in, for example, a truncated cone shape or a hemispherical shape (a truncated cone shape in FIGS. As shown in FIGS. 2 to 4, the connecting cylinder portion 3 has a connecting member 11 in which a box-like connecting body 10 is fixed to the tip of a connecting arm 9 whose base end is brazed to a lens frame 7 of eyeglasses. The engagement projections 6 and 6 can be inserted into the space 12 of the connecting body 10 shown in FIG. 4, and the engaging projections 6 and 6 are a pair of locking holes penetrating the facing surface portions 13 of the connecting body 10. It is adapted to be fitted to 15, 15. In this embodiment, as shown by the alternate long and short dash line in FIG. 3, the solid cylinder 14 containing the fragrance is deformed in the connecting cylinder 3 when the connecting cylinder is pushed into the connecting body. Even by (deformation as shown in FIG. 5), it is housed so that it does not protrude from the tip of the connecting tube portion.

The procedure for attaching the nose pad 1 having the above structure to the connecting body 10 is as follows. That is, first, the connecting cylindrical portion 3 is pushed into the space 12 of the connecting body 10 with the engaging projections 6 and 6 aligned with the left and right locking holes 15 and 15. At the time of this pushing, as shown in FIG. 5, the side surfaces 5 and 5 which face each other are elastically curved and deformed inward, and the engaging projection 6 and the locking hole 15 are fitted to each other, and then the connecting tubular portion is formed. 3 is elastically restored to the initial state. Particularly, in this embodiment, since the side surface portions 4 and 4 on which the engaging protrusions are provided are formed to be relatively thin, the inward elastic deformation of the opposed side surface portions can be performed more easily. Be done. Further, the other side surface portions 5 and 5 are, in advance, as shown by the alternate long and short dash line in FIG.
If it is slightly outwardly curved, its elastic deformation is more easily performed. Even if the side surfaces 5 and 5 are curved in this way without forming the side surfaces 4 and 4 to be thin, the inward elastic deformation of the opposing side surfaces 4 and 4 is facilitated.

When exchanging the nose pads connected in this way, since the connecting tube portion 3 has a rectangular tube shape, that is,
Since the edge portions at both ends of the opposing side surface portions 4 and 4 on which the engaging protrusions are provided are connected to each other and the connecting cylinder portion 3 has a structure that is strong against twisting, FIG. As shown in FIG. 5, even when the nose pad 1 is twisted (arrow F) and removed while the movement of the connecting tubular portion 3 is restricted by the inner surface portion 14 of the void 12 of the connecting body 10, the connecting tubular portion The nose pad can be removed without causing excessive deformation of 3.
Also, when the connecting arm is made of a relatively soft material,
Even if the nose pad is gripped and the bending condition of the connecting arm is adjusted, the connecting cylinder portion is not unduly deformed.

FIG. 7 shows another embodiment of the nose pad according to the present invention. In the nose pad 1,
The connecting cylinder portion 3 is provided so as to project from the exposed surface of the substrate 16 embedded in the pad body 2. The connecting tube portion 3 is made of a synthetic resin such as nylon and is integrally formed with the substrate 16, and has a rectangular tube shape with an open front end and a rectangular cross section, for example. The side surfaces 4 and 4 facing each other are formed to be relatively thin, and the outer surfaces of the side surfaces 4 and 4 are engaged so as to bulge into, for example, a truncated cone shape or a hemispherical shape (hemispherical shape in FIG. 7). The protrusions 6 and 6 are provided in the same manner as described above.

[0019]

The present invention has the following excellent effects. By simply pushing the connecting cylinder portion of the nose pad into the space of the connecting body at the tip of the connecting arm, the engaging projection and the locking hole of the connecting body are naturally fitted together,
The nose pad will be connected by one-touch operation.

Moreover, the connecting tubular portion has a tubular shape in which the edge portions at both ends of the side surface portion provided with the engaging projection are connected to each other, and has a structure resistant to twisting. ing.
Therefore, when the nose pad is replaced, even if the nose pad is twisted and removed, the connecting portion is not unduly deformed. From this, for example, by preparing several types of nose pads of different colors, even an amateur wearer himself / herself can replace the nose pads easily and surely.

In particular, when the side surface portion provided with the engaging projection is formed to be relatively thin, the side surface portion is likely to be elastically deformed inward. Further, when both side surface portions not provided with the engaging protrusions are curved outwardly, the both side surface portions are easily deformed, and the elastic deformation is facilitated.

Since the nose pad according to the present invention includes the bottomed connecting tube portion, it is possible to use this to store a solid substance containing a fragrance in the connecting tube portion. When configured in this way, the fragrance emitted from the solid matter can be drifted around the nose, and the scent can be enjoyed while wearing glasses.
