Description

  The present invention relates to a pad that contacts a nose to support spectacles.

  In general, glasses are provided with pads that contact the nose to support the glasses. Such a pad is provided at a position in contact with the nose when wearing spectacles with respect to the front or the like.

  This pad plays a role of enhancing the effect of correcting vision and enhancing the comfort of wearing glasses. That is, since the positional relationship between the eye and the lens is determined according to the position where the pad hits the nose, the pad plays a role of adjusting the position of the lens to improve vision correction. Also, the size (height and width) of the nose and the shape of the nose bridge vary depending on the person, and in order to improve the comfort of wearing glasses, it is necessary to improve the fit of the pad to the nose.

  Therefore, a technique is known in which the position of the pad can be finely adjusted by providing a pad at the tip of the pad foot and plastically deforming the pad foot portion so that the position of the pad relative to the front can be adjusted (Patent Document 1). reference). A technique is also known in which the tip of the pad foot is formed into a spherical shape and the pad is swingable with respect to the spherical portion (see Patent Document 2).

  However, these techniques usually require a metal pad foot. Therefore, for example, when it is not desired to use a metal member for design reasons, the above-described conventional technique cannot be applied.

  Further, when a plastic material such as acetate is used as the front material, and when a metal pad foot is used, a problem is likely to occur at the joint between the front and pad foot.

  That is, when the plastic front and the metal pad foot are bonded with an adhesive or the like, there is a problem that it is generally difficult to increase the adhesive force. In addition, when part of the metal pad foot is embedded in the plastic front and joined, there is a problem that the front is prone to cracking, and the part where the pad foot is embedded in the front cannot be made thin. There is a problem that there are restrictions.

On the other hand, when a pad made of the same material is fixed to a plastic front such as acetate using a solvent, there is an advantage that a high bonding force can be obtained. On the other hand, in this case, there is a problem that it is extremely difficult to adjust the position of the pad. In other words, when the position of the pad is finely adjusted after bonding the pad to the front, the position adjustment is very laborious, for example, it is deformed while heating.

  By doing so, the position of the pad relative to the front can be changed without replacing the pad body with another one.

  In addition, said each structure can be employ | adopted combining as much as possible.

  As described above, according to the present invention, the position of the pad relative to the front can be easily adjusted without using a metal material (but not denying the use of a metal material). And can improve the fit to the nose.

  The best mode for carrying out the present invention will be exemplarily described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. .

  With reference to FIGS. 1-6, the pad which concerns on Example 1 of this invention is demonstrated.

<Glasses frame>
The spectacle frame will be described with reference to FIG. FIG. 1 is a part of a perspective view of a spectacle frame to which a pad according to Embodiment 1 of the present invention is applied. In FIG. 1, the vicinity of the pad is shown in a perspective view.

  The spectacle frame includes a front 100 that constitutes the front portion of the spectacle frame, and a pad 10 that contacts the nose to support the spectacles. The front 100 includes a pair of rim portions 101 that hold a lens and a bridge portion 102 that connects the pair of rim portions 101. In this embodiment, the front 100 is made of an acetate material.

  The pad 10 includes a base 20 fixed to the front 100 and a pad main body 30 configured to be detachable from the base 20.

<Pad>
In particular, the pad according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a perspective view of members constituting the pad according to Embodiment 1 of the present invention. FIG. 3 is a top view of members constituting the pad according to Embodiment 1 of the present invention. FIG. 4 is a front view of members constituting the pad according to Embodiment 1 of the present invention. FIG. 5 is a side view of members constituting the pad according to Embodiment 1 of the present invention. 3 to 5, (A) shows a pad main body, and (B) shows a base.

  The base 20 is integrally provided with a base portion 21 fixed to the rim portion 101 of the front 100, a holding portion 22 that holds the pad main body 30, and a connecting portion 23 that connects the base portion 21 and the holding portion 22. ing. The base 20 is made of the same material as the front 100, that is, an acetate material which is a hard plastic material. And the base 20 is being fixed with respect to the front 100 with high joining force because the bottom face part of the base part 21 is fixed to the rim | limb part 101 using a solvent.

  The pad body 30 is a member that comes into contact with the nose and is made of a soft material such as silicone. The pad main body 30 is provided with a fitting hole 31 having substantially the same shape as the outer shape of the base 20. Moreover, the external shape of the pad main body 30 is comprised by the left-right asymmetric curved-surface shape seeing from the front (refer FIG. 4).

  According to the pad 10 configured as described above, the pad main body 30 can be attached to the base 20 by fitting the base 20 into the fitting hole 31 of the pad main body 30. When the pad main body 30 is mounted, one end of the base 20 is hooked to one end (one end in the vertical direction) of the fitting hole 31 and the other end of the pad main body 30 is pulled. Thus, the pad main body 30 can be easily mounted by being fitted to the base 20 while being deformed. Further, when removing the pad main body 30 from the base 20, the pad main body 30 can be easily removed by pulling one end of the pad main body 30 and turning the pad main body 30 while deforming it.

<Excellent points of this embodiment>
As described above, according to the pad 10 according to the present embodiment, the pad main body 30 can be easily attached to and detached from the base 20 fixed to the front 100. Therefore, the positional relationship of the pad 10 (substantially the contact portion with the nose in the pad 10) with respect to the front 100 can be adjusted only by changing the pad main body 30 to an appropriate shape and size. Thereby, while being able to adjust the positional relationship of an eye and a lens, the fitting property with respect to the nose of the pad 10 can be adjusted. By preparing a plurality of types of pad bodies 30 having different shapes and sizes, it is possible to cope with various nose sizes and nasal bridge shapes.

  Further, in the present embodiment, the outer shape of the pad main body 30 is configured by a curved shape that is asymmetrical when viewed from the front. Therefore, the positional relationship of the pad 10 with respect to the front 100 can also be changed by switching the pair of pad main bodies 30 left and right. This point will be described with reference to FIG. FIG. 6 is a schematic view of the positional relationship between the pad and the front according to the first embodiment of the present invention as viewed from the front. Only a part of the front is shown.

As described above, the outer shape of the pad main body 30 is configured by a left-right asymmetric curved shape when viewed from the front. Therefore, each shape in a pair of pad main bodies 30 is not the same, and has a mirror surface relationship. For example, as shown in FIG. 6A, the left side in the figure is the pad body 30X and the right side is the pad body 30Y. FIG. 6B shows a state in which the pad main bodies 30X and 30Y are exchanged, the pad main body 30Y is arranged on the left side in the figure, and the pad main body 30X is arranged on the right side in the figure.

  As can be seen from these drawings, the pad main bodies 30X and 30Y are configured by curved surfaces that are asymmetrical when viewed from the front, and therefore, when arranged as shown in FIG. 6 (A) and in FIG. 6 (B). In this case, the positional relationship of the pad 10 with respect to the front 100 is different. For example, the distance between the pair of pad bodies 30X and 30Y is wider in the case shown in FIG. 6A (W1> W2).

  In this way, by configuring the outer shape of the pad main body 30 with a left-right asymmetric curved shape when viewed from the front, two types of positional relationships of the pad 10 with respect to the front 100 can be realized by one set of pad main bodies 30. .

  Further, since the pad main body 30 is made of a soft material, it can be easily attached to and detached from the base 20 and has excellent fit to the nose.

  In this embodiment, the base 20 is made of an acetate material and is fixed to the front 100 made of the acetate material using a solvent. Therefore, the bonding force between the front 100 and the base 20 can be increased without damaging the front 100.

  7 and 8 show a second embodiment of the present invention. In the first embodiment, an example in which a single fitting hole having substantially the same shape as the outer shape of the base is provided in the pad main body is shown. However, in this embodiment, a plurality of fitting holes are provided in the pad main body. Thus, the case where the mounting position of the pad main body with respect to the base can be changed is shown. Since other configurations and operations are the same as those in the first embodiment, the description of the same components will be omitted as appropriate.

  FIG. 7 is a schematic cross-sectional view of members constituting the pad according to the second embodiment of the present invention. FIG. 8 is an explanatory diagram for explaining how to change the attachment position of the pad according to the second embodiment of the present invention.

  Also in the present embodiment, as in the case of the first embodiment, the pad 10a includes a base 20a fixed to the front and a pad body 30a configured to be detachable from the base 20a. In the same way as in the first embodiment, the base 20a is connected to the base portion 21a fixed to the front rim portion, the holding portion 22a that holds the pad main body 30a, and the base portion 21a and the holding portion 22a. And a connecting portion 23a.

  And in the pad main body 30a which concerns on a present Example, the fitting hole 31a and the fitting hole 31b are provided in two places up and down. Thus, if the base 20a is fitted into the upper fitting hole 31a of the pad main body 30a, the pad main body 30a can be fixed at a position shifted downward with respect to the base 20a (FIG. 8A). reference). Further, if the base 20a is fitted in the lower fitting hole 31b of the pad main body 30a, the pad main body 30a can be fixed at a position shifted upward with respect to the base 20a (see FIG. 8B). ).

  In the present embodiment, the upper fitting hole 31a and the lower fitting hole 31b are configured such that the opening side communicates. Thereby, when changing the fitting hole which fits the pad main body 30a, even if it does not remove the pad main body 30a once, a fitting hole can be changed by sliding the pad main body 30a.

  Thus, according to the pad 10a according to the present embodiment, in addition to obtaining the same effect as the first embodiment, the pad for the base 20a can be changed by changing the fitting hole into which the base 20a is fitted. The attachment position of the main body 30a can be changed. Therefore, the position of the pad 10a with respect to the front can be changed without replacing the pad main body 30a with another one.

  In particular, in the present embodiment, since the position of the pad main body 30a with respect to the base 20a can be changed to two places, upper and lower, it is suitably used for glasses equipped with a progressive lens (progressive bending force lens) like reading glasses. be able to. In other words, for example, in the case of reading glasses, the bending rate varies depending on the position of the lens. In general, the glasses are worn when looking far, and the glasses are shifted up or down when looking near. Used as such. And when looking near, it is normally used with the glasses held by hand. On the other hand, if the pad 10a of the present embodiment is used, the position of the glasses can be shifted up and down by changing the fitting hole into which the base 20a is fitted. In either case, the hand can be kept away from the glasses.

  In the present embodiment, an example in which fitting holes are provided at two positions on the upper and lower sides of the pad body has been described. However, fitting positions are provided at two left and right positions, and the position of the pad is changed in the width direction. You may be able to do it. Further, the number of fitting holes is not limited to two but may be three or more. For example, it can be provided at four locations, top, bottom, left and right.
