Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens with a frame capable of improving the sales form of spectacles. At the distribution stage, the components of the spectacles are supplied to each individual as a composition which can be easily assembled, or The parts are supplied in an assembled state so that the user of the spectacles can assemble them into the final product.

[0002]

2. Description of the Related Art Eyeglasses have made great progress in terms of shape, material, and decoration with the changes of the times. Basically, a pair of lenses are fitted to a rim and connected by a bridge to form a front part. The final product of the spectacles is the integrated product of wisdom, hinges, temples, moderns, and pads. In addition, rimless glasses without a rim have become popular in recent years. On the other hand, since the appearance of plastic lenses in recent years, there has been a tendency to attach importance to fashionability by dyeing lenses or using both sunglasses and prescription glasses. As a result, the number of people who easily wear eyeglasses has increased, and there are two or three individuals.
It is not uncommon to own an individual and glasses.

However, a so-called frame for fixing the lens is not so inexpensive, and many lenses have different specifications in terms of right and left.
In addition, it is necessary to grind the outer peripheral shape of the lens to match the rim shape, and for rimless eyeglasses, it is necessary to make holes for fixing frame parts, and it is inevitable to rely on the manufacturer when making eyeglasses, so the result It becomes expensive and the eyesight deteriorates year by year, so new glasses must be purchased every time the eyesight is inconvenient.

On the other hand, with the development of resin lenses, it has become possible to supply high-quality, light-weight, shock-resistant and inexpensive lenses, and in recent years, the phrase "Utsurunsu" is used as a catchphrase for easy use. Cameras are widely used. The feature of this product is that the essential parts of the camera components, that is, the lens, shutter, film, and dark box are supplied as a unit, and the concept that the film and the camera are originally sold separately is broken. It is understood that there was a new idea of attaching a film to a film and selling it.

It is impossible to mass-produce eyeglasses with a single design document like the above-mentioned lens-attached film.
Because the requirements for manufacturing eyeglasses are frequency,
There are individual differences in astigmatism, hyperopia, myopia, interpupillary size, etc., and the number of types of eyeglasses that are individually adapted is enormous.

When requesting eyeglasses, the user usually first has a prescription prepared by an ophthalmologist. Based on this prescription, we place an order to a retail store (eyeglass store), but if there is no compatible lens in stock, we will go through a distribution stage such as a processor (= lab) → wholesaler (= trading company) → lens maker. Have to procure it. Also, after obtaining the desired lens, one must ask the processor to grind the outer edge of the lens to match the rim shape of the frame to the user's preference. Due to such a stage, it took a considerable amount of time to obtain the product and required a considerable cost.
In order to shorten these periods, it is necessary to stock various types of lenses at each distribution stage, and some of them may become unmarketable due to the deterioration of the resin due to aging. In any case, when a user of spectacles wants new spectacles, it is not possible to obtain it easily and inexpensively because it requires various processes.

Further, although the pair of eyeglasses is a pair of left and right eyes, it is customary that the left and right eye prescriptions are different.
This is also a factor that significantly lengthens the delivery period of eyeglasses. Therefore, in order to shorten the delivery time as much as possible, there are many applications for removable frames that are convenient for exchanging only the lens, and among them, disposable eyeglasses as shown in Japanese Utility Model Laid-Open No. 63-80526 are also proposed. ing. Further, it has become common to perform grinding to match the rim at an eyeglass store.

[0008]

SUMMARY OF THE INVENTION The present invention is based on the concept of integrating a spectacle frame (hereinafter referred to as a frame) with a lens in order to provide a lens for spectacles which is light, strong against impact and inexpensive. The present invention has been accomplished.

The problem to be solved is that the user of the spectacles can select the appropriate lenses based on the prescription of the eye and manufacture the spectacles of the finished product by the user himself with the minimum number of members necessary for wearing. An eyeglass member is provided.

[0010]

According to the present invention, a highly utilized prescription lens is singly used, and a side surface of the lens is ground in advance to a normal size, and an appropriate lens is selected based on a prescription.
The temples, wisdom, bridges, pads, etc. are provided in the state of being properly attached to the lens so that the eyeglass user can assemble them to the final product from the left and right framed lenses freely selected by the user. Provide lens divided bodies with a frame for the left eye portion or the right eye portion that are divided around the connecting members such as or the like, respectively, as one product unit, and then combine them with those on the opposite side at the distribution stage or user. It is configured so that it can function as a pair of eyeglasses.

To facilitate the assembly and to freely combine the lenses into one set, a part of the frame, the temple and the modern are attached to the lenses.

Further, in order to simplify the assembly, reduce the number of parts, and provide at a lower cost, the structure in which the jig, the temple, and the modern are integrally formed by using a flexible member without using a hinge.

A connecting member such as a bridge on one lens,
Be sure to attach pad feet and pads.

Since the users of spectacles have different physiques,
The length of the bridge is variable so that the interpupillary distance can be arbitrarily selected.

When a lens with an astigmatic degree is used, the side surface of the lens is ground and then a mark of the astigmatic axis is shown at the location to provide a lens which can be erased at the time of use.

For the lens body, a plastic lens is selected as a material that is hard to break and a light material can be used. Acrylic, polycarbonate, etc. can be used, but CR-39, which has high physical properties such as scratch resistance, transparency, and high Abbe number, is particularly hard coated. Uses a lens that is hard to scratch without applying it.

The shape and / or color of each lens and / or frame of the left-eye portion or right-eye portion lens-divided body divided by a connecting member such as a bridge or the periphery thereof is different. .

The individual product form provided is the lens power,
The combination of left eye, right eye, and color is decided by the user side, so the supplier side must thoroughly manage the inventory, and the specifications are displayed on the bar code display for each product unit. The contents of the sold product are easily managed by recording and pasting or printing the display.

As the spectacles, the correlation positions of the wisdom, the bridge and the lens are almost constant, and the pattern is provided so that the user can easily assemble the pattern and the position is determined. The horizontal and vertical axes and the degree of astigmatism tilt are described.

[0020]

Embodiment 1 FIG. 1 is a perspective view of an embodiment of a lens with a frame according to the present invention. 1 is a lens, 2 is a wisdom, 3 is a temple, 4 is modern, 5 is a hinge, 6 is a bridge, 7 is a pad leg, and 8 is a pad. Lens 1, wisdom 2 and bridge 6
The lens 1 is fixed by a plurality of screws 9 and nuts 10, and can be attached and detached for the time being.

A user who wants to purchase eyeglasses is required to purchase the spherical degree (SPH) and astigmatic degree (CY) described in the prescription.
L), astigmatic axial power (AXIS) and interpupillary distance (PD)
The lens for the right eye and the lens for the left eye are selected by. In this embodiment, an example of a user without astigmatism will be described. Since there is no astigmatism and only the spherical power is of interest, the manufacturer provides half of the glasses as shown in FIG. 1 for each spherical power. Since the bridge 6, the pad foot 7 and the pad 8 are integrated, it is not always necessary to assemble them to the lens 1 as shown in FIG. 1, and the user can select separately.

Although FIG. 1 shows the one for the left eye, the lens for the right eye (not shown) is also provided integrally with the lens, wisdom, temples, moderns, hinges and the like. This right eye lens is also selected according to the prescription. When the pair of left and right members are selected, the user fixes the member for the right eye to the bridge 6 with the screw and the nut. As another method for fixing the lens and the wisdom or the bridge, an adhesive is used, or an elastic body is used to hold the bridge between the lenses to fix the lens, and an inexpensive but solid fixing method is used.

With respect to the setting of the interpupillary distance, an accurate interpupillary distance can be set by placing glasses assembled on the pattern paper 11 of the actual size shown in FIG. 2 and matching the outer dies of the lenses.
For this work, an enlarged perspective view of the bridge 6 will be described with reference to FIG. The lens fixing bases 6-1 and 6-2 slide on each other in the frame 12. A set screw 13 is provided to prevent this sliding. First, the set screw 13 is loosened and the left and right lenses are placed at the interpupillary distance that the user fits. While maintaining this state, the push screw 13 is tightened. Thus the glasses are ready. The position of the pad 8 is adapted to the nose by appropriately bending the pad foot 7 with pliers or the like.

In FIG. 1, reference numeral 33 is a bar code display, and the contents to be described are assembled for left eye, wisdom, temple, modern and hinge, and lens power, color and other bridges are attached. It means that the product is
Keeping records with a bar code reader at the point of sale will make it easier for suppliers to respond. In this embodiment, the lens 1 is attached to the surface, but the frame 3 or the modern 4 may be attached or printed to a printable portion. Another bar code display is also attached or printed for the right eye on the opposite side.

[0025]

[Embodiment 2] When an astigmatic user selects a lens, it is necessary to determine a sphere degree (SPH), an astigmatism degree (CYL), an astigmatism axis degree (AXIS) and an interpupillary distance (PD) according to a prescription. is there. First, a predetermined lens is extracted from the storage shelf for the left eye and the right eye. In this case, the astigmatic axial power differs depending on the user, and therefore the lens is preferably round. Also in the method of holding the lens, it is desirable to hold the lens 14 as shown in FIG. It is composed of a tip 15 bent at a substantially right angle, a fixing piece 16 for receiving the lens, and a screw 17.
The tip of the screw 17 is sharp, and when the lens 14 is tightened, the squareness of the wisdom 15 is bent in the direction of opening, so that the repulsive force is constantly applied to the lens so that it does not loosen. Figure 4
In the above, two screws are used, but a notch 18 is provided so that each screw 17 can act independently. Such a lens fixing method is also adopted in the bridge. Further, instead of the hinge, a flexible member such as the spring 21 is used to simplify the structure and reduce the cost.

Next, a means for determining the astigmatic power based on the prescription will be described. The lens is placed on the paper pattern 19 as shown in FIG. The astigmatic axis mark 20 shown on the peripheral portion of the lens 14 shown in FIG. 4 is aligned with the astigmatic power position of the pattern paper 19. While maintaining this position, the bridge and wisdom are fixed at the designated locations on the paper pattern to complete the glasses.

A means for the user to select a lens appropriately without using a prescription will be described. An empirical table of the degree of demand and the frequency of the prescription lens is shown in FIG.
In 39, there is a tendency to be occupied by the shaded area. Therefore, it is advisable to arrange the lens storage shelves installed in the sales floor of the retail store that are in high demand.

As the spectacles for wearing as shown in FIG. 7, the spherical power is 0.5 to 6.0 in the frame in which the lens slides left and right.
A lens having no distortion is attached to the left and right, and cursor lines 30 are put on the horizontal and vertical axes passing through the center of the lens. First, the user selects a lens that can be seen accurately by wearing the above-mentioned glasses with the target of the field of eyesight of 1.2 on the auxiliary examination table or the optometer provided in the sales floor.

The visual acuity of 1.2 is a range that does not cause inconvenience in daily life and is not particularly limited. After selecting a clearly visible lens, the lens is imaged in a mirror and the glasses are slid to the left and right so that the intersection of the cursor 30 is located at the center of the pupil of the eye. The sliding portion 31 provided on the eyebrow of the spectacles is provided with a scale 32 in units of mm so that the interpupillary distance can be known. If the same procedure as in the first embodiment is performed through the above procedure, it is possible to obtain predetermined glasses.

[0030]

[Third Embodiment] It is possible to separately obtain right and left eyeglasses in the first and second embodiments, but it is also possible to make eyeglasses that further promote the fashion. That is, the left and right lenses having different external shapes and different colors can be combined and enjoyed. Lenses and frames have different colors.

[0031]

[Embodiment 4] Although Embodiments 1 and 2 have been described with respect to a lens without a frame, it is also possible to supply with a lens and a frame on one side to which a rim is attached in advance.

As shown in FIG. 8, pipes 22-1 and 22-2 are provided in the eyebrow portion and the bridge portion, respectively, and round rods 23-1 and 23-2 fitted to these are provided. The user arbitrarily selects the right and left lenses and the frame, and fits the tube and the round bar to obtain the finished spectacles. Further, the pipe 22-1 is provided by cutting off a part of the pipe so as to press the round bar 23-1 into which the spring 24 is inserted, and semi-fixing the sliding pipe and the round bar at appropriate positions. I am able to

Further, as shown in FIG. 9, the tube 2 of the eyebrow and the bridge portion
5-1 and 25-2 can be independent. In this case, if the tube lengths are prepared in advance with different lengths, the adjustable range of the interpupillary distance becomes wider. This pipe can be semi-fixed at any position by making a split pin type in which a part is split and holding the round bars 23-1 and 23-2.

The member connecting the eyebrow portion and the bridge portion is a tube and a round bar, but the cross-sectional shape thereof may be a square shape, a concave shape or the like as long as it has a function of fitting.

In the present invention, at least one of the members constituting the spectacles is provided in a connected state, but it is considered that the constituent members can be provided individually without any problem. Needless to say.

[0036]

According to the present invention, the spectacles are not used as a finished product,
Since it is available to the user himself in the previous stage, the spectacle form can be freely selected, and it is easy to assemble it into a desired form, it is not necessary to go through the conventional distribution processing process. Therefore, the minimum delivery time and cost required for the provision of eyeglasses can be achieved, resulting in extremely beneficial results for both manufacturers and consumers.
