Description

  The present invention relates to eyeglass fitting technology. Specifically, it is a technique for measuring the shape and dimensions of the head and relates to the production of a fitting head model which is a tool for fitting.

Glasses do not function as glasses unless they are fitted with lenses of the necessary number to correct the user's eyesight and are fully fitted to exhibit their optical functions.
At the spectacle store, after the user selects the spectacle frame, the fitting is done once. This is called pre-fitting. Decide the lens power and layout, and order the lens from the manufacturer. In many cases, however, it takes delivery time for special processing such as coloring the lens. It is common to have you. In the meantime, in the spectacle store, the lens is framed, but after finishing, it is necessary to perform fitting again when the user comes to pick up the spectacles.
In that case, the user must wait on the spot.

  In order to have the user wait on the spot, the fitting has to be done in a short time, so it is difficult to make a major correction, and there are times when the spectacles technician cannot fully demonstrate the technique.

  In other words, depending on the material of the eyeglass frame, something that cannot be bent easily, for example, it must be warmed up for a considerable time like armor, or there is no frame, so a hole is made in the lens like a so-called rimless frame, Fitting in a short time is impossible with screw-type glasses. In particular, in the case of rimless frames, even if pre-fitting is performed before processing the lens, pre-fitting may become useless if the lens curve is different or if the lens is changed to the user's desired shape. .

  As one method for solving this, there is a method in which fitting data is recorded in advance and glasses are fitted based on this data. For example, a face measuring instrument referred to Patent Document 1 is known, and data such as the length of the temple, the width of the face, and the distance to the upper part of the auricle are left as data for fitting, and Patent Document 4 Further, there is known a device capable of measuring a part of the contour shape of the nose by bringing a measuring device like a nose pad into contact with the side of the nose root of the subject.

Or, as another method of measuring fitting data and using it for eyeglass fitting, it is necessary to measure a face using a facial photograph, create fitting data in a computer, and fold based on this data There is known a technique in which a temple portion is bent and fitted with a power unit or the like (see Patent Document 3).

  Alternatively, as in the above, the position of the ear or nose is determined from the photograph, and the eye gaze of the subject is also captured as data, and the shape of the ear modern and nasal pad for fitting is accurately traced to the relevant part. It is also known to manufacture specific spectacles (custom spectacles) that fit and fit the subject's face by measuring with molding. For example, see Patent Document 5.

In addition, as in Patent Document 2, a method is also known in which a user freely bends a hanging frame glasses-type fitting data detector, puts it into a fitting state desired by the user, and reads this bending state by a machine.

The human head is not necessarily bilaterally symmetric, the right and left face widths are different with the nose at the center, and the manner in which the pinna is attached varies from front to back and up and down. When this is measured with the face measuring instrument as described above, even if the measurement data is sufficient, it is not possible to evaluate how the eyeglass frame should be bent and fitted, and the result of the fitting.
That is, even if the opening angle of the temple or the inclination angle of the side surface of the nasal root ridge is measured, it is difficult to adjust the contact condition of the temple with the head side surface and the contact condition of the nasal pad with the nasal root side surface. Let's go.

In another invention using a face photograph, a face measurement is performed with a photograph, fitting data is created in a computer, and a temple is bent based on this data. It is limited and cannot be delicately crafted according to the human body.
In addition, the invention of a custom spectacle manufacturing device or the like has a drawback that it cannot be used for fitting a spectacle frame in a store because only spectacles with a specific design can be manufactured from the device.
In addition, it is difficult to think that the type in which the user deforms the glasses according to the user's preference is that the user has knowledge about the original optical holding method (fitting) of the glasses.
Furthermore, these devices are too large, and it is inconvenient in terms of cost because a considerable number of engineers are required to operate them.

  In view of the above circumstances, the present invention can be easily measured by wearing like glasses, and can accurately grasp the three-dimensional relative position of the nose and ear of the head and the angle of the ridge of the nose root. An object is to provide a measuring instrument.

The face measuring device 2 that can be accurately grasped can be obtained.

  Further, according to the second invention, the data measured by the face measuring instrument 2 is transferred to the fitting head model 1 by a simple device, and the shape and size of the head of the glasses user are transferred to the fitting head model 1 with the glasses. , And a personal head-shaped restoration structure can be made that can check the degree of fitting (good or bad fitting).

  Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows the fitting head model 1 with glasses.
Finally, the nose root ridge where the spectacles are worn by the fitting head model 1 and the part where the spectacles above the auricle are worn are duplicated as the user's head. Even if the user is not on-site, this device can take enough time to work.
The fitting head model 1 has a stopper, which is released after the work is finished, replaced with a replica of another user's nose and ear, and newly measured by another user's head, It can be used as a head model for fitting multiple human heads.

FIG. 2 shows a face measuring instrument 2 of the present invention. FIG. 6 is a right side view of the face measuring device 2. FIG. 13 is a left side view of the face measuring device 2 hung on the face. The nasal root apical reference back surface 65a of the nasal root apex measuring instrument 60 is applied to the nasal root apex 9 of the measurement subject. FIG. 15 shows an overhead view of the face measuring instrument 2 at this time.
At this time, the nose root apex reference piece support pad 66 is in contact with both sides of the nose root ridge so as to firmly support the face measuring device. If necessary, the pad mounting angle may be changed.
It is important that the nasal root apical reference back surface 65a and the nasal root apex portion 9 are in uniform contact with each other, and the pad supports this measuring instrument, so it is desired to hold it firmly.
On the contrary, if the nose root apex reference piece back surface 65a does not slip, the nose root apex reference piece support pad 66 may be omitted.

Next, the front bar back surface 10b is brought into contact with the forehead. At this time, the nasal root apex angle meter 61 of the nasal root apex measuring tool 60 is pushed forward because the nasal root apex reference single back surface 65a is in contact with the nasal root apex 9.
In the meantime, the nasal root reference single back surface 65a is prevented from coming off from the nasal root crest apex portion 9 or being biased.
Next, as shown in FIG. 15, the left side bar 40 and the right side bar 50 are shrunk so as to come into contact with the side surface of the head and put on the upper part of the auricle.
Thereafter, the right front burst top 21 and the left front burst top 31 are fixed.
Next, in order to maintain the angle and position of the nasal root apex reference piece 65, the nasal root apex reference piece fixing tool 63 is fixed.

The size of the face being measured by the face measuring device 2 will be described with reference to FIG.
FIG. 18 is a schematic view of the head as seen from above. Therefore, the thickness of the device is not described. Usually, the head is asymmetrical, and the front and back positions of the ears are also shifted left and right.
Also, the positions right C and left D on the sidebar at the top of the auricle are different in height and are often not on the same plane.
This height difference is not shown here, but is displayed on the vertical movement scale portion 70a.
The face measuring instrument 2 has a structure in which the front bar 10, the left side bar 40, and the right side bar 50 can be expanded and contracted while maintaining a right angle. Therefore, if the scale attached to each scale portion is read, the position can be represented on the coordinates.
The left face width M is measured when the left side bar 40 is brought into contact with the left temporal surface about the nose root crest 9, and the right face width L is measured when the right side bar 50 is brought into contact with the right temporal surface. .
If the intersection of the front bar 10 and the left side bar 40 is A, and the intersection of the right side bar 50 is B, the distance N from the front bar to the right auricle is between AC and the left auricle from the front bar is between BD It corresponds to the distance O to.
N and O need to be recorded because they cannot be transferred in direct contact even if the fitting head model 1 and the face measuring device 2 are joined later.

This recording method can be performed by reading the scale on the sidebar scale, printing directly on the sidebar with a sign pen, or attaching a sticker that can be easily removed as a mark.
This method of applying the peelable ear position seal 13 can also be useful when the seal mark is sequentially transferred to the left and right auricle root upper molds and finally adjusted to the fitting head model.

The left face width M and the right face width L can be transferred via the connector 300 as will be described later.
At a later date, it may be recorded for the case where the user's face needs to be restored to the fitting head model 1 without being measured by the face measuring device 2.
The scale of the nose root apex scale part 60a indicating the distance between the forehead and the nose root apex part 9 and the scale of the nose root apex angle scale scale part 67 indicating the angle are also recorded for later use.

Next, it is confirmed whether the face measuring device 2 is level with respect to the face. If the right side is lowered, the right side bar 50 is lowered by operating the up / down moving handle 71 of the side bar up / down moving tool 70,
If the left side is lowered, the vertical movement handle 71 of the sidebar vertical movement tool 70 is operated to raise the right sidebar 50 so that the front bar 10 becomes horizontal.
This vertical distance can also be read and recorded by the vertical movement scale 71a.
If this height is significantly different, the left and right face widths M and L are also affected, and the left front burst top 21 and the right front burst top 31 are once again released and started again.

Next, how to make the nose root crest mold 80 will be described with reference to FIG.
As shown in the left figure of Fig. 16 (a), the impression material cut in a horizontally long shape is warmed and softened and applied to the nasal root crest apex sampling area 12 in Fig. 14, and at the same time, pressed well to copy the shape of this part. Like that.

  Here, the impression refers to a female mold in which a shape called an impression material is pressed against a place where the mold is to be collected when the shape of the nose or pinna is duplicated. As the impression material, it is preferable to use a low-temperature heat-softening resin that can accurately copy the shape and has no sanitary problem even if used on the human body.

As shown in Fig. 16 (b), when it cools and solidifies to some extent, it is removed so as not to break the shape, and a male mold is made from this mold.
The object on the right side is a molding material resin. This is filled inside the impression of the previous mold to make a nasal root crest replica 82. The molding material in this case is efficient if it is a two-substance mixed type and solidifies in a few minutes.

  As shown in FIG. 16 (c), the tip of the nose fitting 87 opposite to the sphere is inserted from the rear side of the nasal root ridge replica 82 to the front, substantially at the center of the top, bottom, left and right before the molding material solidifies. This is called a nose root crest mold 80, and FIG. 16 (d) is a finished product.

Next, how to make the left auricle root upper mold 113 and the right auricle root upper mold 123 will be described with reference to FIG.
First, take the impression of the upper left pinna.
FIG. 17 (a) is a left side view of the position measured by the face measuring instrument. At this time, the left side bar 40 is in contact with the forehead, so the front is slightly raised. In accordance with this inclination, the inclination angle of the auricle root upper impression acquisition tool horizontal bar 202a is adjusted as shown in FIG.
The impression material at this time uses the same heat-softening resin as used in the nasal root crest mold 80, and the impression material portion of the auricle root upper impression acquisition tool 202 is warmed and sufficiently softened. To do.
At this time, the impression material is sufficiently wound around the center from the upper part of the auricle root to the rear, and takes the shape of a valley part from the upper half of the auricle to the side of the head. FIG. 17 (b)
The guide of the auricle root upper impression acquisition tool vertical bar 202b is a guide as to whether or not it is vertical, but does not have to be vertical as viewed from the measurement. However, it must be vertical when viewed from the front.
Further, the seal 13 attached to the pinna when measured by the face measuring device 2 may be attached to the impression material.

Next, in order to make the left auricle root upper mold 113, a description will be given with reference to FIGS.
The left side of FIG. 17C is an impression of the upper left auricle root taken using the auricle root upper impression acquisition tool 202 in FIG. 17B.
The figure on the right side shows the auricle root upper mold fixture 201, but a molding material resin is attached to the right end of the auricle root upper mold fixture horizontal bar 201a as shown in the figure. This molding material is also a two-substance mixed type as in the case of the above-mentioned nose type, and a short-term solidified substance is suitable.
This molding material is not attached in advance, but two substances are mixed immediately before taking the mold, and attached around the rotation stop projection 201c at the rear part of the auricle root upper mold fixture 201. This anti-rotation protrusion 201c is for preventing rotation and preventing falling off.
Further, if the molding agent does not rotate with respect to the rod, the rotation stop projection 201c may be omitted.

As shown in FIG. 17D, the auricle root upper-type fixture vertical bar 201b and the auricle root upper impression acquisition tool vertical bar 202b are overlapped so as to be in the same plane.
This is because the angle between the pinna attachment part and the pinna root upper mold taken with the impression material is important.
By making the molding material sufficiently wrap around the impression, if the male mold is molded from the auricle and the valleys on the side of the head, from the upper part of the auricle to the rear, it is possible to reproduce the place where the modernity of the glasses is applied.
Further, the seal attached to the impression material is transferred to the left auricular root upper mold 113 at a corresponding position.

After solidifying, the left auricle root upper mold 113 with the auricle root upper mold fixture horizontal bar 201a is formed by releasing.
Thereafter, as shown in FIG. 17 (e), when the unnecessary portions of the auricle root upper mold fixture vertical bar 201b and the auricle root upper mold fixture horizontal bar 201a are cut off, the auricle root upper mold fixture vertical bar 201b. Is a component to be attached to the left ear fitting 112 of the face dimension reproduction device 3.

  In the same manner, the upper part of the right auricle root mold 123 takes an impression using the auricle root upper impression acquisition tool 202 while referring to the inclination angle of the right sidebar 50 and the right auricle root upper mold fixing tool 201 to the right An auricle root upper mold 123 is produced.

The left auricle root upper mold 113 and the right auricular root upper mold 123 made as described above are attached to the left ear attachment tool 112 and the right ear attachment tool 122 of the facial dimension reproduction apparatus 3 of FIG.
The nose root apex die 80 is inserted into the round nose of the nose die fitting 87 through the groove at the tip of the nose die joining device 85, and is fitted into the round recess in the nose die joining device 85, and the nose die fixing screw 88 is tightened. Do not tighten completely, but determine the nasal mounting angle in a later step, and then fix it completely.
The face dimension reproducing device 3 in which these three parts of the nasal root apex mold 80, the left auricular root upper mold 113, and the right auricular root upper mold 123 are incorporated is referred to as a fitting head model 1.
FIG. 19 is a diagram of the main body of the fitting head model 1. FIG. 1 shows the fitting head model 1 with glasses.

Next, a method of joining the fitting head model 1 and the face measuring device 2 using the joint 300 (see FIG. 5) will be described. See FIG. 8 and FIG.
First, the left ear type horizontal movement slider 90 and the right ear type horizontal movement slider 100 of the fitting head model 1 are moved to the innermost side, and the nose type slider 81 is moved as far back as possible.
Further, the left ear up / down moving tool 111 is operated to move the left auricular root upper mold 113 downward as much as possible. The right auricle root upper mold 123 is also lowered in the same manner.

  The fitting head model 1 includes a left joint joining part 86a and a right joint joining part 86b (see FIG. 19) so that the left joining bar 305b and the right joining bar 305a of the joint 300 can be inserted from above. It has become. FIG. 8 is a view when the insertion is performed.

Further, the connector 300 includes a left mounting groove 304b and a right mounting groove 304a for mounting the face measuring device 2, and the center portion of the front bar bridge portion 11 is placed on the bonding groove 300. FIG. 9 is a diagram when this is placed.
At this time, the left auricular root upper mold 113 and the right auricular root upper mold 123 are separated from the left side bar 40 and the right side bar 50 of the face measuring instrument 2 as shown in FIG.
In addition, the nasal root apex mold 80 and the nasal root apical reference back surface 65a are not in contact with each other.

How to adjust the position and mounting angle of the nose root apex reference piece 65 and the nose root apex die 80 will be described with reference to FIG. 7 which is a cross-sectional view taken along AA in FIG.
First, in the vertical direction, when the user's nasal root crest 9 is measured by the face measuring device 2, the position where the nasal root reference single back surface 65 b is in contact with the height of the nasal root crest mold 80 is matched. Then, the connector moving device 89 is operated to move the connector 300 up and down. This jointer up-and-down moving tool 89 is a screw, and has a structure in which the tip of the screw pushes up the jointer.
Also, other methods can be used as long as they can move smoothly up and down without using screws.

Further, the joint upper part 301 and the joint lower part 302 can be moved back and forth by the back and forth moving device 303 until the nasal root apex reference piece 65 contacts the nasal root apex mold 80. The face measuring device 2 integrated with the upper joint 300 is moved.
The nasal root reference single back surface 65b and the nasal root crest apex die 80 are adjusted to the position measured by the face measuring instrument 2 while shifting in the vertical direction and the front-rear direction by the above two means.
The nose root apex measuring instrument 60 is fixed, and rotates the nose root apex mold 80 to contact the nose root apex mold 80 in parallel with the nose root apex reference back surface 65b as shown in FIG. Then, fix with the nose-type fixing screw 88.

Next, a method for transferring the relative position data of the nose and ear measured by the face measuring instrument 2 to the fitting head model 1 will be described with reference to FIGS.
Since the left auricle root upper mold 113 and the right auricular root upper mold 123 are separated from the left side bar 40 and the right side bar 50, as shown in FIG. The right ear type horizontal movement slider 100 is extended and brought into contact with both side bars.
FIG. 12 shows this as seen from above.

Next, the right ear up-and-down moving tool 121 is operated and moved upward until the part of the valley between the pinna and the head side surface of the right auricle root upper mold 123 hits the lower part of the right side bar 50 of the face measuring device 2.
Next, the nose-shaped slider 81 is moved to move the fitting side head model 1 and the right sidebar 50 as one body back and forth, and to match the position of the upper root of the left auricle determined by the face measuring device 2.
This determination method is based on a method of reading the scale of the right sidebar scale section 50a, printing with a sign pen on the right sidebar 50, or using the ear position seal 13 attached to the left auricle root upper mold 113 as a guide. Also good.
Then, it is fixed with a nose type slider stopper 82.

  Again, check whether the right auricle root upper mold 113 is in contact with the right side bar 50. If not, the right ear horizontal movement slider 100 is moved and brought into contact with the right ear horizontal movement slider stopper 102. .

This time, the left ear type horizontal movement slider 90 is extended and extended until the left auricle root upper mold 123 contacts the left side bar 40.
In addition, the left ear up-and-down moving device 111 of the left ear type up-and-down device 110 is operated in the same manner as the right ear root upper mold, and the left ear root upper mold 113 is moved upward. The part of the valley between the pinna and the side of the head is brought into contact with the lower part of the left side bar 40.
Next, the left ear type back-and-forth movement slider 150 is operated, and the position of the upper part of the left auricle is adjusted to the position determined on the left side bar 40 by using the face measuring instrument. This determining method is the same as that for the right ear. For example, it is also possible to use the ear position seal 13 as in the right side for accurate alignment. When the position of the right auricle root upper mold 123 in the front-rear direction is determined, it is fixed by the left-ear mold back-and-forth moving slider stopper 152.

  Again, it moves until the left auricle root upper mold 113 is in contact with the left side bar or the left ear type horizontal movement slider is operated and surely hits. Then, when it is determined, the left ear type horizontal movement slider stopper 92 is fixed.

Thus, since each slider of the fitting head model 1 is fixed, both the face measuring device 2 and the connector 300 are removed.
As for the removal method, when the jointer up / down moving tool 89 is operated and the jointer 300 is moved upward, it is detached together with the face measuring device 2.

When removed, only the fitting head model 1 is obtained as shown in FIG. 19, and the user's desired glasses can be fitted to this.
If all the stoppers of the fitting head model 1 are released and the ear and nose molds are removed, it can be used by the next user.

Next, another embodiment will be described with reference to the drawings.
FIG. 22 shows the horizontal maintaining face measuring instrument 14. The height of the human auricle upper part and the nose root crest apex part 9 are not the same height, and the horizontal maintenance type face measuring instrument 14 includes a nose root apex measuring instrument vertical movement tool 69 that moves the nose root apex measuring instrument 60 up and down. By operating this, the left sidebar 40 is measured horizontally.

FIG. 20 shows a simplified fitting head model 15.
Since the left side bar 40 of the horizontal maintenance type face measuring instrument 14 is fixed in the vertical direction, the simple left ear 114 of the simple face dimension reproducing device 16 is directly fixed to the left side bar 40 and does not move up and down.
The simple right ear 115 is connected to the right ear type horizontal movement slider 100 via the right ear type lifting / lowering device 120.
The simple left ear 114 and the simple right ear 115 have a simple shape so that it is a little complicated to take the auricle root upper type, and only the position is reproduced without taking the mold.

A nose type lifting device 94 is disposed between the nose root crest die 80 and the nose slider 81.
This is because the nose root crest mold 80 is moved to a height relative to the simplified left ear 114.
Therefore, the simple joint 306 and the simple fitting head model 15 shown in FIG. 21 are simply inserted by inserting the simple joint rod 310 into the joint rod inserter 93 and not moved up and down.

The usage of the simplified fitting head model 15 will be described in a little more detail. The method for measuring each dimension and angle of the head of the person to be measured by the horizontal maintenance type face measuring device 14 is the same as that of the first embodiment except that the horizontal maintenance of the left side bar 40 is taken care of.
Further, the nasal root ridge apex mold 80 is molded from the nasal root ridge apex of the person to be measured, and is the same as in the first embodiment.
The upper left and right auricle root impressions are not taken for simplicity.

A method for transferring the data measured by the horizontal maintenance type face measuring instrument 14 to the simplified fitting head model 15 will be described.
First, the nasal root apex mold 80 is attached to the nasal joining device 85. At this time, the nose-type fixing screw 88 is slightly loosened.
The left ear type horizontal movement slider 90 and the right ear type horizontal movement slider 100 are contracted.
In addition, when the horizontal maintenance type face measuring instrument 14 is joined, the nose type slider 81 is moved backward so that the nose root crest apex die 80 comes behind the nose root apex reference back surface 65a.
Then, the simple right ear 115 is lowered by the right ear type lifting device 120.

Next, the right front bar 20 and the left front bar 30 are fitted into the right mounting groove 304a and the left mounting groove 304b of the simple connector 310.
Next, the left-ear type horizontal movement slider 90 is moved outward and brought into contact with the left side bar 40. At this time, the lower part of the left side bar 40 should be in contact with the upper part of the simplified left ear 114.

First, the nose root elevating device 94 moves the nose root apex portion 80 of the nose root apex portion mold 80 and the nose root apex reference back surface 65a so as to have the same height.
Next, the nasal slider 81 is moved forward, and the nasal root apex mold 80 is brought into contact with the nasal root reference single back surface 65a.
At this time, the nose root apex reference single back surface 65a should be at the angle when the measurement subject is measured, so the nose root apex top portion 80 of the nose root apex die mold 80 is inclined to the nose root apex reference single back surface 65a. According to the corner, it is fixed with a nose-type fixing screw 88.

Next, the right-ear type horizontal movement slider 100 is moved outward and brought into contact with the right side bar 50.
The right ear up / down moving tool 121 is operated so that the upper part of the simplified right ear 115 is in contact with the lower part of the right side bar 50.
Further, the nose slider 81 is operated so as to be aligned with the position of the simple right ear 115 and the position determined by the right sidebar scale portion 50a.

Next, the left ear-type back-and-forth movement slider 150 is operated to move the simple left ear 114 to the position defined by the left sidebar scale portion 40a.
After confirming again, the nose type slider stopper 84, the left ear type horizontal movement slider stopper 92, and the right ear type horizontal movement slider stopper 102 are fixed.

The level maintaining face measuring instrument 14 is removed together with the simple connector 310 by pulling it upward.
The simple fitting head model 15 is fitted with glasses to perform fitting.

  Since the simple fitting head model 15 does not have information on the shape of the circumference of the user's ear, the left auricle rear shape copying bar 41 and the right auricle rear shape copying rod 51 are used for the measurement subject's measurement at the time of measurement. It is useful to shape the modern shape of the glasses by keeping the shape along the back of the pinna.

According to the present invention, by installing this apparatus in a spectacle store, it is possible to provide glasses that are more comfortable to wear without causing the spectacle user to wait.
In addition, even if there is no actual glasses, if the restoration structure of the user's head is prepared with this device, fitting is performed using this fitting head model 1 after the glasses are made, and a comfortable wearing feeling is obtained. Can provide glasses.
