Description

[Detailed Description of the Invention] The present invention relates to a marking device attached to a pupillary distance measuring device.

When adjusting glasses, it cannot be said that the glasses are accurate unless the pupils of both eyes match the optical centers of the left and right lenses.

Therefore, in the past, the pupil distance was measured in advance using a measuring device as shown in Figure 1A, and a transparent template was attached to the customer's eyeglass frame, and the user stood next to and in front of the customer wearing the transparent template. Since the center position of the pupil within the frame was marked using a felt-tip pen, etc., the positioning was extremely inaccurate, especially in the case of bifocal lenses or large diameter frames with high fashionability. Accurate positioning was difficult.

The present invention provides a marking device that can be easily attached to a known twin-tube pupillary distance measuring device, and can easily and accurately mark the center of the pupil in a desired frame while measuring the pupillary distance. It is something to do.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1A shows a known pupillary distance measuring device, in which a viewing section 31 for the measurer is formed at one end of two parallel cylinders 30, and a viewing section 31 for the measurer is formed at each other end for the person to be measured (customer).
A semicircular scale plate 33 is attached to the front end of a partially cut out upper half of the eyepiece part 32 of B, and between the two scale plates 33 is the cylindrical body 3.
A nose hook 34 that connects 0 is constructed integrally with the scale plate 33. Therefore, when using the measuring device A, the person to be measured B must
0, the measurer pinches a knob 35 attached to the cylinder 30 near the viewing part 31, rotates the shaft 36 that passes through the cylinder 30, and measures the area inside the cylinder 30. The distance from the center of the nose to the pupil of the subject B is measured for each eye of the person B by rotating shielding wings (not shown) attached to the shafts 36 so as to be rotatable.

FIG. 1C shows a marking device according to the present invention, which will be described in detail below.

Reference numeral 1 denotes a clamping part that can be detachably attached to the two cylindrical bodies 30 of the measuring device A. In the figure, one elastic piece made of metal or synthetic resin is attached from the outside of the two cylindrical bodies 30. It is configured to be fixed to the cylindrical body 30 by wrapping it around the body and tightening both ends thereof with bolts 2 and nuts 3 on the lower side of the cylindrical body 30.
Reference numeral 4 denotes a short and small support whose lower end is rotatably attached to the center of the above-mentioned clamping part 1 on the upper side of the cylinder 30, and on its upper end surface there is a deep groove extending from the side of the support 4 through the center. A semicircular long groove 5 and a groove 6 perpendicular to the long groove 5 are cut to form protrusions 7 at the four corners, and the lower half of the base end of the cylindrical lever 8 is fitted into the long groove 5. , its upper half is pressed by a presser fitting 23 that is screwed to the protrusion 7 on the upper end surface of the support column 4, and the lever 8 can freely rotate within the long groove 5 serving as a bearing. The lever 8 is structured so that it can rotate itself and can also rotate the support column 4 by turning it in the horizontal direction.

A narrow slit 9 is cut perpendicularly to the axial direction in the upper half of the center of the proximal end portion that fits into the long groove 5 of the cylindrical lever 8. A pinion 10 having a diameter slightly smaller than the inner diameter of the lever 8 is inserted, and the pinion 10 is attached to a pinion shaft 12 which is supported by the center of a cap 11 fitted into both ends of the lever 8 and inserted into the lever 8. The tip of the pinion shaft 12 is made to protrude from the end surface of the lever 8, and a knob 13 is attached thereto.
The pinion 10 is inserted into the slit 9 by the knob 13.
It is configured to rotate within the

Reference numeral 14 denotes support plates provided on both sides of the slit 9 of the lever 8, and a concave groove 15 such as a dovetail is cut horizontally symmetrically on the upper part of each of the opposing sides.

Reference numeral 16 denotes a slide portion having a rack 17 on its lower surface that engages with the pinion 10, protruding ridges 24 on both sides that are slidably fitted into the groove 15, and a sliding portion 16 on both ends of its upper surface. A clamping piece 18 is formed for clamping a marking tool 21 such as a felt-tip pen, and the slide part 16 performs a prone movement by rotating the lever 8, and also rotates the lever 8.
By rotating the knob 13 at the tip, it can be slid back and forth between the support plates 14.

The marking device according to the present invention is constructed as described above, and in use, as shown in FIG. 20 or a transparent template is fitted into the frame 19, and when the tip of the felt-tip pen 21 is being measured on the marking device C, the tape 20 of the frame 19 is attached.
Attach the device at a distance so that it does not come into contact with the device. The measuring device A and the nose hook 34 of the frame 19 are connected by a suitable locking device 22, and the measurer measures the pupil distance of the person B from the viewing portion 31 of the measuring device A, and at the same time Keep an eye on 31 and mark mark C
Guide the tip of the felt-tip pen 21 to the center position of the pupil on the tape 20 of the frame by rotating or horizontally rotating the lever 8, and move the felt-tip pen 21 forward by turning the knob 13 at the tip of the lever 8. A mark is made on the tape 20.

Therefore, according to the present invention, it can be easily attached to a known pupillary distance measuring device, and it is possible to accurately mark the center position of the pupil within a desired frame while looking through the measuring device. It has various advantages such as being able to locate the center of the pupil extremely easily and accurately even when adjusting a lens or a lens for a large-diameter frame, and having a simple structure and easy manufacturing.
