  When the pad foot and bridge are integrated, when the external force is applied to the eyeglass frame with the eyeglass frame attached to the face, the pad foot and bridge integrated product and the eyeglass frame are connected to each other. The force transmitted from the pad foot and the force acting between the rims of the glasses frame are added. Therefore, compared to the case where the pad foot and the bridge are separately connected to the frame, the burden on the connection portion between the integrally formed product of the pad foot and the bridge and the spectacle frame is increased.

  In order to solve the above-described problem, in the first aspect of the present invention, a first bridge that connects a pair of lenses, a clings that holds a nose pad, a clings that are integrally formed, and a pair of lenses is formed. Eyewear is provided comprising a second bridge that connects.

  In the above eyewear, the ends of the second bridge may be extended to form the crings. In the above eyewear, the first bridge and the second bridge may connect the pair of lenses at different positions. In the above eyewear, the first bridge and the second bridge may connect the pair of lenses at different positions when the eyewear is viewed from above.

  In the above eyewear, the first bridge and the second bridge may be attached to different positions on the pair of rims of the eyewear. In the eyewear described above, the first bridge and the second bridge may be attached to different surfaces of the pair of rims. In the above eyewear, one of the first bridge and the second bridge may be attached to a front facing surface of the eyewear, and the other of the first bridge and the second bridge may have a pair of rims connected to each other. It may be attached to the opposite surface.

  The eyewear may further include a nose pad holding unit that holds the nose pad. In the above eyewear, the crings may extend linearly with respect to the nose pad holding part and be connected to the nose pad holding part.

  It should be noted that the above summary of the invention does not enumerate all the necessary features of the present invention. In addition, a sub-combination of these feature groups can also be an invention.

An example of glasses 100 is shown roughly. An example of the elements on larger scale which looked at the bridge part from the front side is shown roughly. An example of the elements on larger scale which looked at the bridge part from the back side is shown roughly.

  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention. Hereinafter, embodiments will be described with reference to the drawings. In the description of the drawings, the same or similar parts may be denoted by the same reference numerals, and redundant description may be omitted. The drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio, and the like may be different from the actual ones. In addition, for convenience of explanation, there may be a case where the drawings have different dimensional relationships or ratios.

  FIG. 1 schematically shows an example of glasses 100. The glasses 100 include a lens 110 and a glasses frame 120. The glasses 100 may include a pair of lenses 110. The glasses 100 and the glasses frame 120 may be an example of eyewear.

  The eyeglass frame 120 holds a pair of lenses 110. The glasses frame 120 includes a rim 122, an armor 124, a hinge 125, a temple 126, a modern 128, a first bridge 130, a second bridge 140, a crings 142, a pad box 144, and a nose pad. 160 may be included. The pad box 144 may be an example of a nose pad holding unit.

  The rim 122, the armor 124, the hinge 125, the temple 126, and the modern 128 are provided in a pair of left and right. The rim 122 holds the lens 110. The armor 124 is provided outside the rim 122 and holds the temple 126 rotatably by a hinge 125. The temple 126 presses the upper part of the ear part of the user's head to sandwich the part. The modern 128 is provided at the tip of the temple 126.

  The first bridge 130 connects the pair of lenses 110. The second bridge 140 connects the pair of lenses 110. Thereby, when a force is applied to the spectacle frame 120 from the outside, it is possible to reduce the force applied to the connection portion between the second bridge 140 and the lens 110 or the rim 122. This effect is prominent when the second bridge 140 and the crings 142 are integrally formed.

  When the second bridge 140 and the crings 142 are integrally formed, if the external force is applied to the spectacle frame 120 with the spectacle frame 120 attached to the face, the second bridge 140 and A force transmitted from the clings 142 and a force transmitted from the lens 110 or the rim 122 are applied to the connection portion between the integrally formed product of the clings 142 and the lens 110 or the rim 122.

  However, by providing the first bridge 130 that connects the pair of lenses 110 separately from the second bridge 140, deformation of the lens 110 or the rim 122 can be suppressed. As a result, it is possible to reduce the force transmitted from the lens 110 or the rim 122 to the connection portion between the integrally molded product and the lens 110 or the rim 122, and to prevent the connection portion from being damaged.

  Here, connecting a pair of lenses includes not only a case where lenses are directly connected but also a case where lenses are indirectly connected. For example, the case where the rims holding the lenses are connected to each other is also included. The first bridge 130 may connect the rims, and the second bridge 140 may connect the lenses. The pair of lenses may be two physically separated lenses, or the pair of lenses may be integrally connected.

  The term “coupled” refers to joining together so that, for example, the first bridge 130 or the second bridge 140 and each of a pair of lenses or rims are brazed, screwed, fitted, or the like. It means that a pair of lenses or rims are joined together by fixing them firmly. The case where the first bridge 130 or the second bridge 140 and each of the pair of lenses or rims are simply in contact is not included.

  The first bridge 130 and the second bridge 140 may connect the pair of lenses 110 at different positions. Thereby, the force applied to the lens 110 or the rim 122 can be dispersed.

  The first bridge 130 and the second bridge 140 may connect the pair of lenses 110 at different positions when the eyeglass frame 120 is viewed from above. The first bridge 130 and the second bridge 140 connect the pair of lenses 110 at a position where at least a part of the first bridge 130 and the second bridge 140 overlap when the eyeglass frame 120 is viewed from the front. You can do it. With these configurations, the strength against the force that bends the glasses frame 120 back and forth is further improved. The front side of the spectacle frame 120 is the front and the back side of the spectacle frame 120 is the rear.

  The first bridge 130 and the second bridge 140 may be attached to different positions of the pair of rims 122 of the eyeglass frame 120. The first bridge 130 and the second bridge 140 may be attached to different surfaces of the pair of rims 122. One of the first bridge 130 and the second bridge 140 is attached to the front surface of the eyeglass frame 120, and the other of the first bridge 130 and the second bridge 140 has a pair of rims 122 facing each other. It may be attached to a surface. With these configurations, the connection between the first bridge 130 and the rim 122 and the connection between the second bridge 140 and the rim 122 can be complementarily complemented.

  The first bridge 130 and the second bridge 140 may be connected to each other. Thereby, lenses can be connected more firmly. The first bridge 130 and the second bridge 140 may be spaced apart. Thereby, when the force is applied to the spectacles frame 120 from the outside, it can bend freely compared with the case where the 1st bridge 130 and the 2nd bridge 140 are connected.

  The second bridge 140 may be formed integrally with the crings 142. The second bridge 140 may extend from the end of the second bridge 140 to form the crings 142. This reduces the force applied to the lens 110 or the rim 122 as compared with the case where the second bridge 140 and the crings 142 are not integrally molded and are attached to different positions of the lens 110 or the rim 122. Can do. For example, the force for twisting the lens 110 or the rim 122 can be reduced.

  The clings 142 may hold the nose pad 160. The clings 142 may be connected to the pad box 144 at one end thereof. The crings 142 may have a rod-shaped portion that extends linearly from the pad box 144. The clings 142 may position the glasses frame 120 relative to the face of the user of the glasses 100.

  Here, the second bridge 140 and the crings 142 are integrally formed when the second bridge 140 and the crings 142 are manufactured by deforming one material. A case where the krings 142 is manufactured in the same process by casting, pressing, or the like can be exemplified. In addition, even when the second bridge 140 and the clings 142 are separately manufactured and combined to form one member, the second bridge 140 and the clings 142 are connected to the rim 122 or the lens. In the case where the second bridge 140 and the crings 142 are not attached to different positions 110, the second bridge 140 and the crings 142 can be illustrated as a single unit.

  The second bridge 140 and the crings 142 are preferably manufactured by deforming one material, or manufactured in the same process. Thereby, the manufacturing process of the spectacles frame 120, the 2nd bridge | bridging 140, and the Klings 142 can be simplified. Moreover, the manufacturing cost of the spectacles frame 120, the 2nd bridge | bridging 140, and the Klings 142 can be suppressed.

  The pad box 144 holds the nose pad 160. The pad box 144 may hold the nose pad 160 movably. The pad box 144 may house a portion of the nose pad 160. There may be a gap between the pad box and the portion of the nose pad 160 housed in the pad box 144. The nose pad 160 abuts on the nose of the user of the glasses 100 and positions the glasses frame 120 with respect to the face of the user of the glasses 100.

  FIG. 2 schematically shows an example of a partial enlarged view of the bridge portion as seen from the front side. As shown in FIG. 2, the nose pad 160 may include a nose pad main body 262 and a nose pad attachment portion 264. The nose pad body 262 may include a resin such as polyester or silicone resin, or may include a metal such as titanium.

  The nose pad attaching portion 264 attaches the nose pad main body 262 to the glasses frame 120. The nose pad attaching portion 264 and the nose pad main body 262 are coupled, and a part of the nose pad attaching portion 264 is accommodated in the pad box 144 and is movably fixed with a screw or the like, whereby the nose pad 160 is attached to the glasses frame 120. May be attached to. The nose pad attachment portion 264 may be disposed on the nose pad main body 262, or a part of the nose pad attachment portion 264 may be embedded in the nose pad main body 262. The nose pad main body 262 and the nose pad attachment portion 264 may be integrally formed.

  In the present embodiment, the first bridge 130 is attached to the front surface 222 of the rim 122. The second bridge 140 is attached to the corners of the mutually facing surface 226 and back surface 228 of the rim 122. The first bridge 130 and the second bridge 140 are a pair of lenses 110 at a position where at least a part of the first bridge 130 and the second bridge 140 overlap when the eyeglass frame 120 is viewed from the front. Are connected.

  In this case, the connection strength of the connection portion between the first bridge 130 and the rim 122 presses the pair of rims 122 from the left and right as compared with a case where a force for pulling the pair of rims 122 to the left and right is applied to the spectacle frame 120. Weak against power. On the other hand, since the second bridge 140 is attached to the mutually opposing surfaces 226 of the rim 122, it is relatively strong against the force of pressing the pair of rims 122 from the left and right. Thereby, even if it is a case where the force which presses a pair of rim | limb 122 from right and left is applied to the spectacles frame 120, the force added to the connection location of the 1st bridge | bridging 130 and the rim | limb 122 can be reduced.

  In addition, the connection strength of the connection portion between the second bridge 140 and the rim 122 is a force that pulls the pair of rims 122 to the left and right as compared to the case where a force for pressing the pair of rims 122 from the left and right is applied to the spectacle frame 120. Weak against. On the other hand, since the first bridge 130 is attached to the front surface 222 of the rim 122, the first bridge 130 is relatively strong against the force that separates the pair of rims 122 left and right. As a result, even when a force for pulling the pair of rims 122 to the left and right is applied to the spectacle frame 120, the force applied to the connecting portion between the second bridge 140 and the rim 122 can be reduced.

  The connection point between the first bridge 130 and the rim 122 and the connection point between the second bridge 140 and the rim 122 may be arranged at different positions when the eyeglass frame 120 is viewed from the front. For example, in the present embodiment, the first bridge 130 and the rim 122 are connected in the vicinity of the corner at the upper center of the spectacle frame 120 among the corners of the rim 122 and at a position below the corner. The second bridge 140 and the rim 122 are connected in the vicinity of the center of the corner of the rim 122. Thereby, the intensity | strength of the spectacles frame 120 can further be improved.

  In the present embodiment, the case where the second bridge 140 is attached to the corners of the opposite surface 226 and the rear surface 228 of the rim 122 has been described. However, the first bridge 130 and the second bridge are described. The attachment method of 140 is not limited to this. The first bridge 130 and the second bridge 140 may be attached to different surfaces of the pair of rims 122. For example, the second bridge 140 is attached only to the mutually opposing surfaces 226 of the rim 122. It may be done.

  In addition, the first bridge 130 may be attached to the mutually facing surfaces 226 of the rim 122, and the second bridge 140 may be attached to the front surface 222, the upper surface 224, or the rear surface 228 of the rim 122. Good. At least one of the first bridge 130 and the second bridge 140 may be connected to the rim 122 on the three surfaces of the front surface 222, the upper surface 224, and the rear surface 228, and a part around the rim 122. May be connected to the rim 122 so as to surround the rim.

  FIG. 3 schematically shows an example of a partial enlarged view of the bridge portion as seen from the back side. As shown in FIG. 3, the second bridge 140 may include a connecting portion 342 that connects the pair of lenses 110, and a bent portion 344 that is disposed between the connecting portion 342 and the crings 142. The bent portion 344 may extend substantially parallel to the front-rear direction of the spectacle frame 120 from the connecting portion 342 and bend downward in the spectacle frame 120 at the end on the crings 142 side.

  The width, thickness, or thickness of the connecting portion 342 may be larger than the width, thickness, or thickness of the krings 142. The bent portion 344 may gradually decrease in width, thickness, or thickness from the side coupled to the connecting portion 342 toward the side coupled to the krings 142. As shown in FIG. 3, the crings 142 may extend linearly from the bent portion 344 toward the pad box 144.

  Thereby, the length of the part where the krings 142 extends linearly can be increased, and the bending of the krings 142 can be increased. As a result, the nose pad 160 can pinch the nose more softly and firmly. It is also possible to easily adjust the position of the nose pad 160 in the front-rear direction of the face. In addition, the nasal bone has a depression near the base of the nose. The nose pad 160 can be pressed against the front side surface of the face of the dent by bending the krings 142 in the front-rear direction of the face. Accordingly, it is possible to improve a sense of stability when the glasses frame 120 is attached to the face.

  On the other hand, as the length of the linearly extending portion of the krings 142 increases, the load applied to the connection portion between the second bridge 140 and the integrally formed product of the krings 142 and the rim 122 or the lens 110 increases. The effect of providing the first bridge separately from the second bridge is even greater in such a case.

  In the present embodiment, the case where the eyewear is glasses has been described. However, eyewear is not limited to this. The eyewear may be any device associated with the eye, and may be a face or head wearing device such as glasses, sunglasses, goggles and a head mounted display and their frames. In the present embodiment, the case where there are two bridges has been described. However, eyewear is not limited to this. The eyewear may include a plurality of bridges, and one of the plurality of bridges may be integrally formed with the crings.

  In the present embodiment, the case where the eyewear includes a rim that entirely surrounds the side surface of the lens has been described. However, eyewear is not limited to this. The eyewear may include a rim disposed only on a part of the side surface of the lens or may not include a rim. If the eyewear does not include a rim, the first bridge and the second bridge may be attached at different positions on the lens.

  In the present embodiment, the case where the eyewear includes a pair of nose pads has been described. However, eyewear is not limited to this. A single nose pad may be disposed between the nose and the integral part of the Klings and the second bridge. For example, the shape of the part that abuts the nose of the integrally formed product of Klings and the second bridge is an arch shape like a mountain or a saddle bridge, and the nose pad having the arch shape is integrally formed with the nose. It may be arranged between the goods.

  In the present embodiment, the case where the lens is a spectacle lens has been described. However, the lens is not limited to this. The lens is not limited to a lens for correcting vision, but may be glass, a resin plate or a resin film, which is not required, or an optical element such as a polarizing lens or a fisheye lens. Further, when the eyewear is a display device such as a head mounted display, glass, a resin plate, or a resin film constituting a part of the display device may be an example of a lens.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
