Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic instruments, and in particular to a frame glasses fitting trial frame and a method for obtaining parameters of frame glasses support components. Background Art

[0002] Glasses fitting is to process glasses that meet the national standards (GB 13511-2011 "Prescription Spectacles", hereinafter referred to as the "national standard") according to the requirements provided in the optometry prescription. Since the state implements production license management for processed glasses products, both the hardware and software in the glasses manufacturing and assembly industries have been continuously improved. It is no longer a difficult problem to assemble a pair of glasses with qualified quality according to the prescription. The current single-vision glasses optometry prescription only marks four parameters: spherical lens, cylindrical lens, axis position, and pupil distance, and does not include parameters closely related to determining the relative position and stability between the optical center of the glasses and the pupil, such as the nose pad of the frame and the bending point of the temple. On the one hand, this cannot ensure that the deviation between the optical center and the pupil of the processed glasses is less than the national standard when worn statically; on the other hand, it is also impossible to ensure that the frame does not deviate after dynamic wearing, which will increase the deviation between the optical center and the pupil.

[0003] The current solution is to let the patient wear the actually purchased glasses and then manually measure the pupil height or take a photo to record the relative position between the pupil and the frame, and transmit the data to the processing workshop to ensure that the deviation between the optical center and the visual axis meets the national standard requirements. However, the above method can only solve the problem in the static wearing environment and cannot solve the deviation introduced by unstable dynamic wearing. The problem of dynamic wearing stability can be solved by increasing the inventory of different sizes of frames and letting the patient find the frame with the best stability through the method of physical fitting. However, due to the increased inventory cost of the store, it is actually very difficult to carry out. Summary of the Invention

[0040] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the art to which the present invention belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless defined as here.

[0041] For the convenience of understanding the embodiments of the present invention, the following will further explain with several specific embodiments as examples in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0042] See Figures 1 to 6 , the present invention provides a frame glasses fitting rack for obtaining parameters and adjusting the support and stabilizing components such as the nose pads and temple arms of frame glasses, including a beam frame structure 1. The two sides of the beam frame structure 1 are respectively connected to a pupil frame 2 and a temple arm frame 3. The pupil frame 2 is used for installing trial lenses, and the temple arm frame 3 is used for measuring the size of the temple arms of the glasses. The beam frame structure 1 is provided with a nose pad structure 4 in the middle on the side facing the user's nose for measuring the distance and angle between the nose pads of the glasses.

[0043] The nose pad structure 4 includes a bushing 41 and a pair of spaced-apart nose brackets 42. The bushing 41 is located at the center of the bridge structure 1 and is of a double-barrel structure. One side of the nose bracket 42 is movably connected to the bushing 41, enabling the nose bracket 42 to rotate relative to the bushing 41 and change the included angle between the nose brackets 42. The nose pad structure 4 also has a first engaging and positioning structure, which is used to hinder the rotation of the nose bracket 42, enabling the nose bracket 42 to be stably in several preset states of mutual included angles. When a sufficiently large torque is continuously applied, the hindrance of the first engaging and positioning structure can be overcome to enable the nose bracket 42 to continue rotating.

[0044] The temple frame 3 includes a first bracket 31 and a second bracket 32 that are movably connected to each other. One side of the first bracket 31 is hinged to the bridge structure 1, and its outer surface also has a first scale (not shown in the figure). The second bracket 32 is sleeved on the other side of the first bracket 31, and the second bracket 32 can move along the surface of the first bracket 31. The other side of the second bracket 32 also has a bent portion 322 for hanging the temple frame 3 on the ear root. The temple frame 3 has a second engaging and positioning structure, which is used to hinder the movement of the second bracket 32 and enable one end of the second bracket 32 to correspond to a preset position of the first scale when the second bracket 32 stops moving. By reading the reading of the first scale, the distance from the user's ear root to the face can be obtained, that is, the bending point of the temple can be obtained.

[0045] Further, in the preferred embodiment provided by the present invention, as Figure 2 、 4 shown in and 5, the first bracket 31 is of a strip-shaped structure, and the second bracket 32 has a blind hole for accommodating the first bracket 31. One side of the first bracket 31 extends into the blind hole of the second bracket 32, enabling the second bracket 32 to slide along the surface of the first bracket 31. The second engaging and positioning structure includes: the first bracket 31 has a plurality of spaced-apart protrusions 311, and the second bracket 32 has a plurality of card holes 321 that cooperate with the protrusions 311. The card holes 321 are of a through-hole structure. When the protrusions 311 extend into the card holes 321, the side portions of the protrusions 311 are in contact with the side portions of the card holes 321, hindering the movement of the second bracket 32. The second bracket 32 as a whole is preferably made of a plastic material such as resin. When a sufficiently large pulling force is applied, the edge of the card hole 321 and the part of the second bracket 32 around it are deformed by the extrusion of the protrusions 311, enabling the protrusions 311 to disengage from the cooperation with the card holes 321, and the first bracket 31 and the second bracket 32 can resume relative movement. The number of the protrusions 311 is equivalent to the number of gear positions, and the spacing of the protrusions 311 is appropriately set according to actual needs. By adjusting the relative position of the second bracket 32 and the first bracket 31 and selecting an appropriate gear position, the spacing is the margin, and its function is to avoid discomfort caused by an overly tight formed spectacle frame.

[0046] In a preferred embodiment provided by the present invention, the first engaging and positioning structure includes: a nose bracket 42 having a rotating shaft on one side, and the rotating shaft extends into a hole of a bushing 41; a plurality of adjacent engaging groove portions 411 are provided on the side wall of the hole of the bushing 41, and a cam 421 is provided at the top of the rotating shaft. The convex side of the cam 421 can be embedded into the recess of the engaging groove, so that the bushing 41 hinders the rotation of the nose bracket 42. Similar to the second engaging and positioning structure, when a sufficiently large torque is applied, the engaging groove portions 411 and the cam 421 are deformed by extrusion, so that the cam 421 disengages from the recess of the engaging groove portion 411, and the rotating shaft drives the nose bracket 42 to continue to rotate. Similar to the second engaging and positioning structure, the engaging groove portions 411 also function as gears, and their intervals and numbers are appropriately set according to actual needs. For example, three adjacent engaging groove portions 411 shown in the figure.

[0047] In a preferred embodiment provided by the present invention, the bridge structure 1 is used to adjust the distance between the lens frames 2, that is, the interpupillary distance of the spectacle frame. The bridge structure 1 includes a slide rail frame 11 and a pair of connecting arms 12. The slide rail frame 11 has a through groove, as Figures 2 to 4 shown, the through groove runs through the slide rail frame 11 along the length direction and has an opening at the lower part. The pair of connecting arms 12 respectively extend into the through groove from one side and are symmetrically arranged. The connecting arms 12 can move relative to the slide rail frame 11. The bushing 41 is installed in the center of the slide rail frame 11; each connecting arm 12 is respectively hinged to a first bracket 31 through one side, and each connecting arm 12 is also connected to a lens frame 2 respectively. The inner side of the slide rail frame 11 (towards the user's nose side) has an opening 111, which can expose the connecting arms 12 located in the through groove, for visually displaying the position of the connecting arms 12 from the upper side. A second scale is also provided on the top of the slide rail frame 11. Taking the opposite ends of the two connecting arms 12 as the reference parts, the readings corresponding to the second scale are read. The second scale is set in the manner of the prior art. It should be understood that it has scale lines for the central reference and is arranged symmetrically with the central reference scale line as the axis, which can ensure the accurate adjustment of the relative position of the lens frames 2.

[0048] A structure similar to the first engaging and positioning structure can also be provided for the bridge to position and read the connecting arms 12.

[0049] In a preferred embodiment provided by the present invention, the temple frame 3 also has a temple stabilizing structure, as Figure 7 shown, which specifically includes:

[0050] One end of the first bracket 31 has a cylindrical bushing 36. A rotating shaft 34 is sleeved in the center of the bushing 36, and the rotating shaft 34 is connected to the connecting arm 12 at both ends. The bushing 36 has a through hole 35 penetrating radially. One side of the friction pin 33 extends into the through hole 35, and the friction pin 33 can move along the through hole 35 so that its end contacts the rotating shaft 34, achieving the effect of hindering the rotation of the first bracket 31 and stabilizing the first bracket 31 at an appropriate position. The friction pin 33 can be a screw (with threads in the through hole 35).

[0051] In the preferred embodiment provided by the present invention, the spectacle frame 2 further has a plurality of lens clips for loading the lenses for optometry. The specific method is based on the prior art and will not be elaborated here.

[0052] The frame glasses provided by the present invention are designed with an individualized customization system for frame glasses. The system consists of three modules: a trial frame with the functions of measuring the spectacle frame size and refractometry, a face-frame-visual axis relationship measurement sticker, and a pupil position mapping and reduction production software. It can automatically generate adjustment drawings for parameters such as the nose pads and the bending points of the temple arms of the spectacle frame and installation drawings for the optical center positions of the lenses for each customer. Without increasing the inventory of spectacle frames, it can minimize the degree of deviation of the optical centers of the lenses from the visual axis in the static and dynamic wearing environments of frame glasses, ensure visual quality, and avoid visual fatigue and myopia progression caused by the deviation of the glasses. The usage method of this frame glasses is as follows:

[0053] Through the freely adjustable nose pads, temple arms, and interpupillary distance, there are 10 sizes of nose pads, and the bending points of the temple arms and the interpupillary distance are continuously adjustable. The selection principle of the nose pads is that they can firmly and comfortably fit on the line connecting the inner canthi of the two eyes. The adjustment principle of the bending points of the temple arms is that they can firmly and comfortably fit on the auricles. The adjustment principle of the interpupillary distance is to minimize the distance between the pupils of both eyes deviating from the midpoint of the same-side spectacle frame ring; read the scale degrees on the slide rail frame, nose pad frame, and temple arm frame to obtain the face-frame-visual axis relationship and make a face-frame-visual axis relationship measurement sticker;

[0054] This sticker can be pasted on the support piece of the spectacle frame after adjusting the nose pads and temple arms. Instruct the volunteer to look at a distant visual target, and then use a mobile phone to take a face photo (turn on the flash function). As Figure 7 and 8 shown, the distances from the right eye R and left eye L pupil reflection points to the vertical center line of the spectacle frame are respectively defined as the right eye and left eye horizontal eccentricity values ( Figure 7 and 8 the letter scales A1B1C1D1E1A2B2C2D2E2 on the abscissa in). The distances from the right eye R and left eye L pupil reflection points to the bottom edge of the spectacle frame ring are respectively defined as the right eye and left eye vertical eccentricity values ( Figure 7 and 8The digital scale on the vertical coordinate). If the position of the pupil is within the green circle (1, 3), it indicates that the relationship between the face-frame-visual axis is well-matched; if the pupil is between the green circle (1, 3) and the yellow circle (0, 4), it indicates that the relationship between the face-frame-visual axis is well-matched, and it is recommended to use decentered processed lenses and make personalized adjustments to the frame; if the pupil is between the yellow circle (0, 4) and the red circle (C1, 5) / (C2, 5), it indicates that the relationship between the face-frame-visual axis is not well-matched, and it is necessary to use decentered processed lenses and make personalized adjustments to the frame; if the pupil is outside the red circle, it is not recommended for this volunteer to use this frame;

[0055] Determine the assembly position of the optical center of the lens on the frame to be processed according to the data obtained by measuring the face-frame-visual axis relationship measurement sticker, as Figure 7 and 8 shown, its abscissa is the horizontal decentration value when wearing the frame, and the ordinate is the vertical decentration value when wearing the frame.

[0056] In a second aspect, the present invention provides a method for obtaining the parameters of the frame support component of the frame glasses using the above frame glasses trial frame, including the following steps:

[0057] Wear the frame glasses on the user's head;

[0058] Take off the frame glasses; rotate the nose bridge bracket 42, adjust the included angle of the nose bridge bracket 42, and move the second bracket 32;

[0059] Wear the frame glasses after performing the second step on the user's head. If the nose bridge bracket 42 and the second bracket 32 respectively fit with the user's nose and ear, and the frame glasses do not show a tendency to loosen or slip, then read the value corresponding to one end of the second bracket 32 on the first scale, and the value of the included angle of the nose bridge bracket 42; otherwise, repeat the second step until the nose bridge bracket 42 and the second bracket 32 respectively fit with the user's nose and ear, and the frame glasses do not show a tendency to loosen or slip;

[0060] Based on the value corresponding to one end of the second bracket 32 read on the first scale and the value of the included angle of the nose bridge bracket 42, obtain the face-frame relationship.

[0061] Further, in the second step, it also includes: moving the connecting arm 12;

[0062] In the third step, it also includes: if the nose bridge bracket 42 and the second bracket 32 respectively fit with the user's nose and ear, and the frame glasses do not show a tendency to loosen or slip, then read the value corresponding to one end of the connecting arm 12 on the second scale;

[0063] The method further includes: obtaining a face-frame-visual axis relationship based on the value corresponding to one end of the read second bracket 32 on the first scale, the value of the included angle of the nose bracket 42, and the value corresponding to one end of the connecting arm 12 on the second scale.

[0064] In summary, the present invention provides a frame glasses fitting rack and a method for obtaining parameters of a frame glasses support component, including a beam frame structure, with pupil frames and temple frames respectively arranged on both sides of the beam frame structure, and a nose support structure in the center. The nose support structure includes a bushing and a pair of spaced nose brackets.

The frame glasses fitting rack provided by the present invention can adjust the relative positions of components to adapt to various face shapes, reduces the storage quantity of trial glasses, and is convenient to use.
