Description

  The present invention relates to optometry glasses, and more particularly, to optometry glasses that can be tilted so that a mounted optometry lens is retracted backward to the side of the face.

  The optometry glasses are used to check the degree of vision correction by wearing an optometry lens. The optometry glasses are also a temporary frame for making a spectacle frame. If the adjustment and confirmation with the optometry glasses are not sufficient, the user will feel uncomfortable when wearing the final glasses. The current optometry glasses cannot tilt the optometry lens so as to recede to the rear side of the face, and are not compatible with sports glasses. In addition, the optometric lens cannot be tilted forward. Furthermore, there is no adjustment of the width between the wisdoms (the hinges connecting the lens frame and the temple) provided at the left and right ends of the optometry glasses corresponding to the face width (or the distance between the ears). In other words, the present optometry glasses only have a height adjustment for the nose and an adjustment of the position of the optometry lens that can be slid in the left-right direction so as to coincide with PD (Pupil Distance). Since other numerical values necessary for creating the eyeglass frame are measured by other dedicated gauges, it cannot be denied that the final sports glasses may feel uncomfortable.

Patent Document 1 discloses optometry glasses that can simultaneously change the distance between left and right optometry lenses by turning a knob. Patent document 2 discloses glasses for sports.

  FIG. 1 is a perspective view of an optometric glasses according to the present invention. The optometry glasses 100 have a pair of optometry lenses 9. The central nose fixing part 1 is provided with a nose pad 8 that can slide up and down. The nose fixing part 1 corresponds to a part called a bridge in the glasses. A slit is provided on the front surface of the nose fixing portion 1, and there is a needle and a scale indicating the height of the nose pad 8. The nose pad is fixed to the fixed nose portion with a set screw a. Reference numeral 14 indicates a height adjustment of the nose pad 8.

  A pair of rails 2 are attached to the left and right sides of the nose fixing portion 1 so as to be rotatable by hinges. In FIG. 1, the hinge is indicated by the uneven portion of the nose fixing portion 1 and the rail 2. A hinge pin 25 is inserted into a through hole provided in the uneven portion. The hinge pin 25 is configured such that a spring 26 is inserted and presses the joint surface between the nose fixing portion 1 and the rail 2 up and down, and the rotation of the rail 2 is hardened by friction so that the rail 2 can be moved at an arbitrary receding angle θ1. Can be fixed. The turning angle, that is, the receding angle θ1 of the rail 2 can be read with a needle provided on the upper end of the rail 2 on the angle scale on the upper surface of the nose fixing portion 1. Reference numeral 10 indicates adjustment of the retraction angle θ1 of the rail 2. Here, an L-shaped rail having a flat upper surface was used for the rail 2 in order to reduce the weight.

  An optometric lens slide member 4a is slidably mounted on the rail 2. The optometry lens slide member 4a is configured as a hanger with a lower part in the fork. Here, the left and right ends of the lens holder 5 to which the optometry lens 9 is attached are attached with screws so that the forward tilt angle can be adjusted. The forward tilt angle θ2 of the optometry lens 9 can be read by a scale provided on the optometry lens slide member 4a. Reference numeral 13 indicates adjustment of the forward tilt angle θ2 of the optometric lens. A roller that facilitates sliding may be provided between the optometric lens slide member 4 a and the rail 2. When the slide position is determined, the optometry lens slide member 4a is fixed to the rail 2 with a set screw b. The position of the optometry lens slide member 4a can be read on the scale on the upper surface of the rail 2. Reference numeral 11 indicates adjustment of the left-right position of the optometry lens 9 by the optometry lens slide member 4a.

  The wisdom slide member 4b is slidably mounted on the rail 2. The wisdom 3 is connected to the hanger below the wisdom slide member 4b. As a result, the wisdom 3 can be slid, so that it is possible to cope with both a wide face person and a narrow person. When the slide is fixed, it is fixed to the rail 2 with a set screw c, and the position can be read on the scale on the upper surface of the rail 2. One end of Ji 3 is a hinge, and the temple 6 is attached by a hinge screw 17. Reference numeral 12 indicates a width adjustment between Ji 3 and Ji 3. In FIG. 1, the wisdom 3 and the wisdom slide member 4b are directly connected, but the wisdom 3 may be rotatably connected as shown in the drawing circle C1.

  Since the temple 6 is inserted into the sheath 6a and can be pulled out, the length can be adjusted. When the length is fixed, it is fixed with a set screw d. Reference numeral 15 indicates adjustment of the length of the temple 6. As a result, it is possible to cope with a person having a large distance from the ear to the eye or a person having a small distance.

  An ear pad 7 is rotatably attached to the end of the sheath 6a of the temple 6. When the rotation angle is determined, it is fixed with a set screw e. The rotation angle can be read with a scale indicated by the needle. Reference numeral 16 indicates adjustment of the rotation angle of the earpiece.

  FIG. 2 is an example of hinge coupling in the case where the mountain valley portion 27 is provided on the hinge pin of FIG. As shown in FIG. 2A, the hinge pin 25 is provided with a mountain valley portion 27 extending in the axial direction over the entire circumference, and a similar mountain valley portion is also provided in the hinge hole of the nose fixing portion 1. Thereby, the hinge pin 25 is fixed to the nose fixing part 1. On the other hand, as shown in FIG. 2B, the hinge hole of the rail 2 is provided with a protrusion 28 that engages with the peak / valley portion 27 of the hinge pin 25. When the rail 2 is rotated, the protrusion 28 is pushed up by the peak portion of the mountain-and-valley portion 27, and when it reaches the valley portion, the projection 28 is pushed down by the spring and is stably engaged. Accordingly, the receding angle θ1 can be stepped at the pitch of the mountain valley portion 27.

  FIG. 3 is a perspective view when the rail is cylindrical. On the outer periphery of the rail 2, an uneven portion 30 extending in the axial direction is provided. Thereby, both the slide member 4a for optometry lenses and the slide member 4b for wisdom become an annular shape. A concave / convex portion 30 is formed inside the annular ring and inserted into the cylindrical rail 2. The optometry lens slide member 4a and the wisdom slide member 4b can slide straight without any blurring. The optometry lens slide member 4a and the wisdom slide member 4b are fixed by a set screw or a clip (not shown). The lens holder 5 and the wisdom 3 are attached to the lower part of the hanger whose upper part is a semicircular hook. In this example, the optometry lens slide member 4a and the wisdom slide member 4b are composed of two parts, a ring and a hanger.

  FIG. 4 is a plan view when the pair of rails of the optometry glasses shown in FIG. 1 are connected by a turnbuckle. FIG. 2A shows a case where the nose fixing portion and the rail are substantially on a straight line. FIG. 2B shows a case where the nose fixing part and the rail are bent into a letter C shape. The tips of the rods 19 on both sides are provided with screws that are opposite to each other. One end of the rod 19 is rotatably connected to a rod support bracket 20 fixed to the rail 2. When the turnbuckle 18a is rotated in one direction, the rods 19 approach each other. Conversely, when the turnbuckle 18a is rotated in the opposite direction, the rods 19 are separated from each other. When the turnbuckle 18a is rotated so that the rods are separated from each other as shown by arrows in FIG. 4A, the rail 2 bends as shown in FIG. 4B. The degree of bending is indicated by the receding angle θ1. When the turnbuckle 18a is rotated so that the rods approach each other as shown by the arrows in FIG. 4B, the rail 2 returns to the original state as shown in FIG. The turnbuckle 18a was provided on the front side of the optometry glasses 100 so as not to hit the optometer's head.

  FIG. 5 is an operation explanatory view of the turnbuckle of FIG. When the turnbuckle 18a is rotated, the rail 2 rotates around the hinge between the nose fixing portion 1. The left-right force Fo as indicated by the arrow of the turnbuckle 18a does not coincide with the tangential direction of the circumference for rotating the rail 2, but the force Fo is a force Fi toward the rotation center and a force Fr toward the tangential direction. As shown in FIGS. 5A and 5B, the rails 2 on both sides can be simultaneously rotated by the force Fr.

  FIG. 6 is a plan view when the pair of optometry lens slide members of the optometry glasses shown in FIG. 1 are connected by a turnbuckle. Assume that the rail 2 is at a predetermined retraction angle. The turnbuckle 18 b is supported by a rod support bracket 20 fixed to the nose fixing part 1. The rod 19 is formed of a flexible resin portion 29 whose hatched portion is soft. As shown in FIG. 6A, when the rail 2 and the nose fixing portion 1 are in a straight line, the optometry lens slide member 4a can be slid by turning the turnbuckle 18b. As shown in FIG. 6B, when the rail 2 is inclined at the receding angle θ1, the flexible resin portion 29 is curved, but by turning the turnbuckle 18b, the optometry lens slide member 4a can be slid. Note that both a turnbuckle 18b as shown in FIG. 6 and a turnbuckle 18a as shown in FIG. 4 may be provided.
