Description

  This invention relates to a measuring instrument used when making eyeglasses according to an order in an eyeglass shop or the like.

  To prepare eyeglasses that fit well, resist sliding, and have a comfortable fit, the dimensions of the orderer's head, especially the distance between the apex of the left and right ears and the center of the nose pad of the glasses or the glasses lens. It is necessary to know the distance to the apex of.

  However, in the past, in many cases, the staff of an eyeglass store measures the distance by eye measurement and prepares the glasses based on the distance, and it cannot be denied that the glasses are inaccurate, resulting in inferior glasses. There was a thing. In view of this situation, the present inventor simply and easily determines the distance between the apexes of the left and right ears of the wearer and the distance from the center of the nose pad of the glasses or the spectacle lens to the apex of the ears, which has a decisive influence on the fit of the glasses. As a result of research to realize a measuring instrument that can measure accurately, it is completed and proposed here as the present invention.

  A head dimension measuring instrument that measures the distance between the apex of the ear and the distance from the center of the nose pad or the spectacle lens to the apex of the eye in order to fit the glasses to the face, the front part located in front of the eye and the front part A front bar having a hollow cylindrical shape with a nose pad attached to the center of the lower surface, and a temple that extends rearward from the left and right ends of the head and is located on the side of the head. The base is slidably inserted into the inside from the opening at both ends, and it can be pulled out against the urging force of the built-in coil spring, and the pullout position is set by the stopper mechanism attached to the front bar. It is made up of an armor that can be fixed and has a scale that displays the pull-out amount on the front surface. A hollow cylindrical temple bar fixed to the roy, and inserted into the inside from the rear end opening of the temple bar. The pull-out position can be fixed by a stopper mechanism attached to the bar, and a push rod protrudes from the temple bar in the axial direction so as to protrude from the temple bar. By pushing this push rod, The above-mentioned problem is solved by comprising a rod-shaped temple that is slid rearward and is provided with a scale on the side surface for displaying the drawing amount.

With the stopper mechanism provided on the front bar and temple bar being released, it is attached to the head of the person to be measured in the same manner as normal optometry glasses. At this time, when the push rod is pressed with a finger or the like, the temple moves backward smoothly against the biasing force of the coil spring. At this time, the armature is urged inward and the temple forward by the coil spring. However, when it is attached to the head of the subject, the armor slides outward and the temple slides backward, Stop at a position according to the dimensions of the part. At this position, fix the current position of the armor and temple using the stopper mechanism, remove it from the head of the person to be measured in that state, read the respective scales indicating the amount of the armor and temple to be pulled out, and indicate them. The distance between a pair of ear vertices and the distance from the center of the nose pad or the eyeglass lens to the ear vertices is used as data for determining the temple opening width and the modern bending width. Complete glasses that fit the wearer's head.
In this way, you can obtain important data for eyeglass preparation just by reading the scale values, so anyone can finish glasses with excellent fit without relying on intuition, skill, or experience. Have.

The perspective view of one Example of the head dimension measuring device which concerns on this device.

  A head dimension measuring device that measures the distance between the apex of the ears and the distance from the center of the nose pad to the apex of the ear in order to fit the glasses to the face, the front part located in front of the eyes and the left and right ends of the front part A front bar having a hollow cylindrical shape with a nose pad attached to the center of the lower surface, and openings at both ends of the front bar. The base is slidably inserted into the inner part of the machine so that it can be pulled out against the biasing force of the built-in coil spring, and the pullout position can be fixed by a stopper mechanism attached to the front bar. And the front part is composed of a scale that indicates the amount of drawer on the front. A hollow tube-shaped temple bar and a temple bar inserted into the inside from the rear end opening of the temple bar. The temple bar can be pulled out against the urging force of the built-in coil spring. The pull-out position can be fixed by the attached stopper mechanism, and a push rod protrudes from the temple bar in the axial direction so as to protrude from the temple bar. By pushing this push rod, the rear side It is made up of a rod-shaped temple provided with a scale for displaying the drawing amount on the side surface.

  FIG. 1 is a perspective view of an embodiment of a head dimension measuring device according to the present invention. In FIG. 1, 1 is a front part located in front of the eye, 2 is bent to the front part 1 by 90.degree. The temple part extended toward the head and located in the head side surface is shown. The front portion 1 has a hollow cylindrical shape, a front bar 4 having a nose pad 3 attached to the center of the lower surface, and a base portion slidably inserted from both ends of the front bar 4 into the inside thereof. 5 is biased in the direction of the nose pad 3, that is, in the central direction, but is pulled out outwardly against this biasing force, and is provided with a stopper screw 6 attached to the upper surface of the front bar 4. This is composed of a substantially L-shaped armor 7 that can fix the pull-out position by a stopper mechanism, and a scale 8 for displaying the pull-out amount is provided on the front surface of the armor 7.

  On the other hand, the temple portion 2 has a hollow cylindrical temple bar 9 whose front end is fixed to the armor 7 and a front end portion is inserted into the inside from the rear end opening of the temple bar 9 and is incorporated by a built-in coil spring 10. Although biased in the direction of the armor 7, that is, in the forward direction, the stopper mechanism such as a stopper screw 14 attached to the upper surface of the temple bar 9 is adapted to be pulled out against the biasing force. Is formed with a rod-shaped temple 11 which can fix the pull-out position, and a push rod 15 is protruded from the front end opening of the temple bar 9 at the front end of the temple 11 in the axial direction. Projected to Further, a temple end 13 for ear-hooking is formed at the rear end of the temple 11, and a scale 16 for displaying the drawing amount is provided on the side surface on the front side.

  This embodiment has the configuration as described above, and is attached to the head of the person to be measured in the same manner as ordinary eyeglasses with the stopper screws 6 and 14 loosened. At this time, when the push rod 15 is pressed with a finger or the like, the temple 11 moves backward smoothly against the urging force of the coil spring 10. At this time, the armature 7 is urged inward by the coil spring 5 and the temple 11 is urged forward by the coil spring 10, respectively. Slide and stop at a position corresponding to the dimension of the head of the person being measured. At this position, the stopper screws 6 and 14 are screwed in, the current positions of the armor 7 and the temple 11 are fixed, removed from the head of the measurement subject in that state, and the scale 8 and the temple 11 indicating the amount of the armor 7 being pulled out. Read the scale 16 showing the amount of drawer, know the distance between the pair of ear vertices by the numerical value shown on the scale 8, and know the distance from the center of the nose pad or the eyeglass lens to the ear vertex by the numerical value shown on the scale 16 Is used as data to determine the opening width of the temple and the modern bending width to complete the glasses that fit the head of each wearer.

  In this way, if the head size measuring device according to the present invention is used, it is possible to obtain important data for the preparation of glasses simply by reading the scales 8 and 16, so anyone can use it regardless of intuition, skill, or experience. It has the effect of easily finishing glasses with a good fit.

  It can be used not only for general myopia and farsighted glasses, but also for sunglasses and sports glasses.
