Description

Technical Field

[0001] The present present inventionpresent invention relates to eyewear such as glasses and sunglasses, and particularly to a technique for attaching nose pads to a resin frame.

Background Art

[0002] Conventionally, in eyewear with a resin frame, the nose pad is integrally formed with the resin frame, and the position and orientation of the nose pad cannot be adjusted, making it difficult to fit the eyewear to the user's face. For this reason, there is a problem that the fitting range of one frame is narrow. Therefore, it has been demanded to attach clips to the frame to make it adjustable with respect to the face.

[0003] For example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2020-20883) discloses a nose pad attached to glasses.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When attaching clips to a resin frame retrospectively, it is necessary to design in advance the position (area, angle) where the clips are to be attached. A configuration is desired that allows the clips to be retrospectively attached without designing the attachment of the clips and enables the eyewear to be worn in the correct position. [[ID=四十]]

[0009] <Example 1> Figures 1, 2, and 3 are rear, top, and perspective views of eyewear fitted with the nose pad assembly of an embodiment of the present invention, respectively. Figures 4, 5, and 6 are rear, top, and perspective views of eyewear fitted with the nose pad assembly of an embodiment of the present invention, respectively.

[0010] The eyewear 1 of this embodiment is a pair of eyeglasses or sunglasses, comprising a synthetic resin frame 2, a pair of temples 3 extending from the left and right ends of the frame 2 to the wearer's temples, lenses 4 attached to lens mounting sections corresponding to the left and right eye positions on the frame 2, nose pads 5 provided in pairs on the inside of the lens mounting sections, and a helicoil 6 attached to the inner side surface of the nose pads 5. As shown in Figures 1, 2, and 3, a nose pad assembly (see Figure 7) with a pad 81 is attached to the helicoil 6. The arrow in Figure 5 indicates the direction of screw insertion into the helicoil 6.

[0011] Figure 7 is a diagram showing the configuration of a nose pad assembly according to an embodiment of the present invention.

[0012] The nose pad assembly of this embodiment includes a base 7, nose pad arms 83, a connecting block 82, and a pad 81.

[0013] The base 7 has a hole 71 through which a screw 9 passes in its center, and a groove-shaped recess 72 that engages with the protrusion 62 of the helicoil 6. As shown in the figure, the recess 72 is preferably located on a straight line (i.e., the radius line) passing through the center on the lower bottom surface of the cylindrical base 7, but it may also be located on a chord in an arc that is part of the outer circumference of the bottom surface of the base 7, as long as it is not an arc shape with the same center as the hole 71. The cross-section of the recess 72 may be a square, a triangle, or a hemisphere.

[0014] A cringles arm 83 is attached to the pedestal 7. For example, the cringles arm 83 may be inserted into a hole formed in the pedestal 7 and fixed to the pedestal 7 by welding or adhesion. The cringles arm 83 is formed of a thin rod-shaped metal. Therefore, since the degree of bending of the cringles arm 83 can be freely changed, the position and orientation of the pad 81 with respect to the pedestal 7 can be freely adjusted.

[0015] One end of the cringles arm 83 is attached to the upper surface of the pedestal 7 (for example, the upper bottom surface of the cylindrical pedestal 7), and the other end is attached to the joining block 82. The joining block 82 is fixed to the back surface side of the pad 81 by adhesion. The joining block 82 is provided with a hole (not shown) into which the cringles arm 83 can be inserted, and the cringles arm 83 may be inserted into the hole and fixed to the joining block 82 by welding or adhesion. The pad 81 is made of a soft synthetic resin and is adjusted to the position and orientation that contacts the wearer's nose.

[0016] As described above, the helical insert 6 is screwed into the frame 2. The helical insert 6 is cylindrical and has a threaded hole 61 which is a female thread into which a screw 9 can be screwed at its central part, and a convex part 62 which engages with the concave part 72 of the pedestal 7. Further, a thread for screwing into the frame 2 is formed on the outer peripheral surface. The convex part 62 is provided at a position corresponding to the concave part 72 of the pedestal 7 (for example, the position of a straight line (that is, a radius line) passing through the center on the upper bottom surface of the cylindrical helical insert 6). That is, the convex part 62 may be provided at a position of a straight line (that is, a radius line) passing through the center on the upper bottom surface of the cylindrical helical insert 6 similar to the concave part 72, but if it is not an arc shape with the same center as the threaded hole 61, it may be provided at the position of a chord in an arc which is a part of the outer peripheral circle of the bottom surface of the helical insert 6. The cross section of the convex part 62 may be square, triangular, or hemispherical. By determining the length of the helical insert, the depth of the hole of the frame 2 for inserting the helical insert 6, and the initial position when the helical insert 6 is attached, the position of the convex part 62 of the helical insert 6 when attached to the frame 2 can be set at a determined position.

[0017] Note that an insert may be used instead of the helical insert 6. The insert has a screw hole into which the screw 9 can be screwed in its central part, and a convex part that engages with the concave part 72 of the pedestal 7, and is adhered or press-fitted into a hole formed in the frame 2.

[0018] The screw 9 is inserted into the hole 71 of the pedestal 7 and screwed into the screw hole 61 of the helical insert 6, whereby the pedestal 7 is attached to the helical insert 6, and the cling assembly is fixed to the frame 2. Further, since the concave part 72 of the pedestal 7 and the convex part 62 of the helical insert 6 engage with each other, the rotational position of the screw 9 of the pedestal 7 and the helical insert 6 is fixed, and displacement of the pad 81 after attachment to the frame 2 can be suppressed.

[0019] FIG. 8 is a configuration diagram of another cling assembly of an embodiment of the present invention. In FIG. 8, the differences from the cling assembly shown in FIG. 7 will be mainly described, and the description of the same points as the cling assembly shown in FIG. 7 will be omitted.

[0020] The cling assembly shown in FIG. 8 includes a pedestal 7, a cling arm 83, a joining block 82, and a pad 81.

[0021] The pedestal 7 has a hole 71 through which the screw 9 passes in its central part, and a convex part 73 that engages with the concave part 63 of the helical insert 6. As shown in the drawing, the convex part 73 may be provided at a position on a straight line passing through the center (i.e., a radius line) on the lower bottom surface of the cylindrical pedestal 7. However, if it is not an arc shape having the same center as the hole 71, it may be provided at a position of a chord in the arc. The cross section of the convex part 73 may be a quadrilateral, a triangle, or a hemisphere. The cling arm 83 is attached to the pedestal 7.

[0022] As mentioned above, the Helicoil 6 is screwed into the frame 2. The Helicoil 6 has a screw hole 61 in its center, which is a female thread into which a screw 9 can be screwed, and a recess 63 that engages with a protrusion 73 of the base 7. Furthermore, a screw thread for screwing into the frame 2 is formed on its outer surface. The recess 63 is provided at a position corresponding to the protrusion 73 of the base 7. That is, the recess 63, like the protrusion 73, is preferably provided at a position on a straight line (i.e., a radius line) passing through the center on the upper bottom surface of the cylindrical Helicoil 6, but it may also be provided at a position on the chord of the arc, as long as it is not an arc shape with the same center as the screw hole 61. The cross-section of the recess 63 may be a square, a triangle, or a hemisphere. As mentioned above, an insert may be used instead of the Helicoil 6.

[0023] The screw 9 is inserted into the hole 71 of the base 7 and screwed into the screw hole 61 of the helicoil 6, thereby attaching the base 7 to the helicoil 6 and fixing the cling assembly to the frame 2. In addition, since the convex portion 73 of the base 7 and the concave portion 63 of the helicoil 6 engage with each other, the rotational position of the screw 9 of the base 7 and the helicoil 6 is fixed, which suppresses misalignment of the pad 81 after it is attached to the frame 2.

[0024] Figure 9 is a diagram of another nose pad assembly according to an embodiment of the present invention. In Figure 9, the differences from the nose pad assembly shown in Figure 7 will be mainly explained, and explanations of points that are the same as those of the nose pad assembly shown in Figure 7 will be omitted.

[0025] The nose pad assembly shown in Figure 9 includes a base 7, nose pad arms 83, a connecting block 82, and a pad 81.

[0026] The base 7 has a hole 71 through which a screw 9 passes in its center, and a recess 72 that engages with the protrusion 62 of the Helicoil 6. The cling arm 83 is attached to the base 7. For example, the cling arm 83 can be inserted into a hole drilled in the side of the base 7 and fixed to the base 7 by welding or adhesive. One end of the cling arm 83 is attached to the side of the base 7, and the other end is attached to the connecting block 82.

[0027] The screw 9 is inserted into the hole 71 of the base 7 and screwed into the screw hole 61 of the helicoil 6, thereby attaching the base 7 to the helicoil 6 and fixing the cling assembly to the frame 2. In addition, since the recess 72 of the base 7 and the protrusion 62 of the helicoil 6 engage with each other, the rotational position of the screw 9 of the base 7 and the helicoil 6 is fixed, which suppresses displacement of the pad 81.

[0028] The base 7 shown in Figure 9 has a recess 72, but it may also have a protrusion 73 as shown in Figure 8.

[0029] Figure 10 is a diagram of another nose pad assembly according to an embodiment of the present invention. In Figure 10, the differences from the nose pad assembly shown in Figure 7 will be mainly explained, and explanations of points that are the same as those shown in Figure 7 will be omitted.

[0030] The nose pad assembly shown in Figure 10 includes a base 7, nose pad arms 83, a connecting block 82, and a pad 81.

[0031] The base 7 has a hole 71 through which a screw 9 passes in its center, and a recess 74 that engages with the protrusion 64 of the Helicoil 6. The cross-section of the recess 74 may be hemispherical, quadrilateral, or triangular. The cling arm 83 is attached to the base 7.

[0032] As mentioned above, the Helicoil 6 is screwed into the frame 2. The Helicoil 6 has a screw hole 61 in its center, which is a female thread into which a screw 9 can be screwed, and a protrusion 64 that engages with a recess 74 in the base 7. One or more protrusions 64 of the Helicoil 6 are provided, with a spherical surface protruding from the upper surface of the Helicoil 6. Multiple spherical recesses 74 are provided on the lower surface of the base 7 at positions corresponding to the protrusions 64 of the Helicoil 6. The cross-section of the protrusion 64 may be hemisphere, quadrilateral, or triangular. As mentioned above, an insert may be used instead of the Helicoil 6.

[0033] The screw 9 is inserted into the hole 71 of the base 7 and screwed into the screw hole 61 of the helicoil 6, thereby attaching the base 7 to the helicoil 6 and fixing the cling assembly to the frame 2. In addition, since the recess 74 of the base 7 and the protrusion 64 of the helicoil 6 engage with each other, the rotational position of the screw 9 of the base 7 and the helicoil 6 is fixed, which suppresses misalignment of the pad 81 after it is attached to the frame 2.

[0034] The base 7 shown in Figure 10 has a recess 74, but it may also have a protrusion as shown in Figure 8.

[0035] As described above, the eyewear according to the embodiment of the present invention allows for fitting so that the eyewear is worn in the correct position. Therefore, it is possible to provide eyewear that is less likely to shift even when posture changes, and the eyewear can perform its original protective function. Furthermore, the lenses will not fog up due to the eyewear shifting, and the field of vision will be maintained. In addition, since the frame does not come into contact with the human body, deterioration of the frame due to sebum can be suppressed. Moreover, the positional relationship between the nose pad assembly and the frame is fixed, and the positional shift of the nose pads can be suppressed.
