Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass frame synthetic resin plate used for producing eyeglass frames, a method for manufacturing the same, and an eyeglass frame.

[0002]

2. Description of the Related Art It is more conventional than in the past to partially make a spectacle frame emit light in order to recognize the location of the spectacles in the dark and avoid trampling the spectacles in the dark. Are known.

[0003] As a technique devised so that the spectacle frame partially emits light in a dark place, for example, the actual Kaihei 2-392.
Japanese Patent Laid-Open No. 09 discloses that a tape having a light-storing effect is held on an ear hanging temple of a spectacle frame. Further, Japanese Patent Application Laid-Open No. 51-75460 discloses a photoluminescent agent applied to an eyeglass frame which has been baked.
Japanese Patent No. 193523 discloses a lens frame of a spectacle frame or a recess formed in a temple, which is filled with a coating material containing a thermoplastic resin containing a phosphorescent agent as a main component.

[0004]

However, the spectacle frame which is made to emit light by utilizing the above-mentioned conventional technique has the following problems. That is, actual Kaihei 2-
According to the technique disclosed in Japanese Patent No. 39209, when the eyeglasses are repeatedly used for a long period of time, the luminous tape held on the vine may be peeled off. Also, Japanese Patent Laid-Open No. 51-75460 and JP-A-60-193523
According to the technology of the publication, the phosphorescent paint applied to the spectacle frame or filled in the concave portion of the spectacle frame may be worn or fallen off. There was a problem that it was difficult to maintain.

By the way, a material that absorbs the energy of light such as sunlight or a fluorescent lamp, converts the absorbed light energy into visible light, and gradually emits light even after the supply of the energy of light is stopped to emit light for a certain period of time. That is, as a material that emits light after the stimulation is stopped when it is stimulated by light, there are a phosphorescent agent and a fluorescent agent in addition to the above-described phosphorescent agent. Among them, the fluorescent agent emits light for an extremely short time immediately after the stimulation is stopped, and the phosphorescent agent has a property of emitting light within a certain time even after the stimulation is stopped. Further, the phosphorescent material has a property that the emission time is extremely long with respect to phosphorescence.

Therefore, if the spectacle frame is made of a synthetic resin mixed with a luminescent agent such as a phosphorescent agent, a phosphorescent agent, a fluorescent agent, etc., the above-mentioned problem, that is, the luminescent tape is easily peeled off and reduced, and the luminescent coating material is used. There is no problem that the initial light emission performance is not maintained due to wear of the light.

However, when the above-mentioned luminescent agent is simply uniformly mixed into the entire synthetic resin forming the spectacle frame to maintain a desired luminescent performance, the amount of the luminescent agent in the surface layer portion is too small. Since sufficient light emitting performance cannot be obtained, it is necessary to select the mixing ratio of the light emitting agent so that the amount of the light emitting agent in the surface layer portion of the synthetic resin layer becomes a certain amount or more. Since the above-mentioned luminescent agent, especially the luminescent agent having the longest luminescent time, is extremely expensive, it is necessary to uniformly mix the luminescent agent in the synthetic resin to secure the necessary amount of the luminescent agent in the surface layer portion. However, it is necessary to increase the mixing ratio of the luminescent agent with respect to the synthetic resin, and the spectacle frame made of such synthetic resin is inevitably expensive.

Therefore, in order to recognize the location of the spectacles in a dark place, the inventor of the present application considers that only the surface or the surface layer portion of the spectacle frame needs to emit light entirely or partially. As a result, the present invention has been completed.

That is, according to the present invention, although the amount of the luminescent agent such as the light storing agent is extremely small, only the surface or the surface layer portion of the spectacle frame exhibits the whole or part of the sufficient luminescent performance. It is an object of the present invention to provide a synthetic resin plate for eyeglass frames and a method for manufacturing the same.

Another object of the present invention is to provide a spectacle frame which exhibits a sufficient luminescence performance for recognizing the whereabouts of spectacles, although the amount of the luminescent agent such as a luminous agent used is extremely small. To aim.

A further object of the present invention is to provide a spectacle frame which does not deteriorate in light emitting performance even if the spectacle frame is worn down for a long period of time.

As the synthetic resin block 1, one having a thickness larger than the thickness of the above-mentioned synthetic resin plate P is used. When the synthetic resin block 1 having such a size is used, the entire surface of the synthetic resin block 1 as shown in FIG. At least a part of them is always exposed on the surface of the synthetic resin plate P. Therefore, even if the synthetic resin layer 2 is opaque and has a property of not transmitting light, the surface of the synthetic resin plate P partially emits light. The synthetic resin layer 2 is formed by gathering synthetic resin pellets 21 containing no luminescent agent in layers and heat-sealing each other. Further, the synthetic resin layer 2 and the synthetic resin block 1 are also heat-sealed. In FIG. 2, since the synthetic resin pellets 21 have different colors or different compositions, the boundary line between the pellets 21 ... Appears on the surface of the synthetic resin plate P. However, if the adjacent synthetic resin pellets 21 have the same color and composition, the boundary line disappears due to heat fusion, and a single layer is formed. Further, the size of each synthetic resin pellet 21 can be freely changed, and by mixing the pellets having different hue, transparency, size, etc., a desired pattern pattern can be revealed. be able to.

The luminescent agent contained in the synthetic resin block 1 includes a phosphorescent agent, a phosphorescent agent, and a fluorescent agent.

The emitted luminescent agent emits light after the stimulation is stopped, and the light is emitted through the transparent portion 2a.

The synthetic resin plate P as described with reference to FIG.
According to this, although the surface of the synthetic resin block 1 is not exposed on the surface of the synthetic resin plate P, the surface of the synthetic resin plate P apparently emits light partially. As described above, even if the size of the synthetic resin block 1 is smaller than the thickness of the synthetic resin plate P, it is possible to emit light by providing the synthetic resin layer 2 with the transparent portion 2a. Alternatively, colorless or colored transparent pellets may be used for all the synthetic resin pellets forming the synthetic resin layer 2.

And extends in a longitudinal direction to cross the synthetic resin layer 6 in the longitudinal direction.

In this embodiment, although the synthetic resin layer 6 containing the luminescent agent traverses the plate-shaped synthetic resin layer 5 in the longitudinal direction at a plurality of locations at the same interval, the synthetic resin layer 6 containing the luminescent agent is It suffices that the plate-shaped synthetic resin layer 5 be provided at at least one position in the width direction.

Further, a synthetic resin layer containing a luminescent agent is provided at a plurality of positions in the longitudinal direction of a plate-like synthetic resin layer containing no luminescent agent at predetermined intervals, and contains the respective luminescent agents. The synthetic resin layer may extend linearly in the width direction of the plate-shaped synthetic resin layer 5 and cross the synthetic resin layer in the width direction. In this manner, when the synthetic resin layer containing the luminescent agent traverses the plate-shaped synthetic resin layer in the widthwise direction, the synthetic resin layer containing the luminescent agent is at least in the widthwise direction of the plate-shaped synthetic resin layer 5. All you need is one place.

FIG. 7 is a partial perspective view illustratively showing another embodiment of the spectacle frame synthetic resin plate P according to the invention of claim 4. As shown in FIG. In this spectacle frame synthetic resin plate P as well, the synthetic resin layer 6 containing the luminescent agent is provided at a plurality of positions in the width direction W of the plate-like synthetic resin layer 5 not containing the luminescent agent, at predetermined intervals. The synthetic resin layer 6 containing the luminescent agent is the longitudinal direction L of the plate-shaped synthetic resin layer 5.
6 is similar to that of FIG. 6 in that it extends linearly and crosses the synthetic resin layer 6 in the longitudinal direction. However, the synthetic resin layer 6 containing each luminescent agent is a plate shape not containing the luminescent agent. 6 is different from that of FIG. 6 in that it is exposed only on one surface of the synthetic resin layer 5. In the illustrated example, one side of the plate-shaped synthetic resin layer 5 having the stripe-shaped synthetic resin layer 6 containing the luminescent agent is covered with the synthetic resin thin layer 7, and the synthetic resin layer 6 containing the luminescent agent is thin. I am doing it.

In the embodiment described with reference to FIG. 7, the synthetic resin layer 6 containing a luminescent agent traverses the plate-shaped synthetic resin layer 5 in the longitudinal direction at a plurality of locations spaced by the same distance.
The synthetic resin layer 6 containing the luminescent agent is a plate-shaped synthetic resin layer 5.
It suffices that it be provided in at least one position in the width direction of. Further, a synthetic resin layer containing a luminescent agent is provided at a plurality of positions in the longitudinal direction of a plate-like synthetic resin layer containing no luminescent agent at predetermined intervals, and a synthetic resin layer containing each luminescent agent is provided.

In this manner, when the synthetic resin layer containing the luminescent agent traverses the plate-shaped synthetic resin layer in the widthwise direction, the synthetic resin layer containing the luminescent agent is at least in the widthwise direction of the plate-shaped synthetic resin layer 5. All you need is one place.

FIG. 8 is a partial perspective view illustratively showing still another embodiment of the spectacle frame synthetic resin plate P according to the fourth aspect of the invention. In this spectacle frame synthetic resin plate P, a synthetic resin layer 6 containing a luminescent agent is provided in a thin layer at one location close to one side in the thickness direction T of a plate-like synthetic resin layer 5 not containing a luminescent agent. There is. The plate-shaped synthetic resin layer 5 containing no luminescent agent may be opaque.

In the synthetic resin plate P for eyeglass frames described with reference to FIGS. 1 to 8, synthetic resins used for the synthetic resin block 1 containing the luminescent agent, the synthetic resin thin layer 4, and the synthetic resin layer 6 containing the luminescent agent are as follows. One selected from acetate, propionate, polycarbonate, celluloid, and the like can be preferably used, and as the light-storing agent as a luminescent agent, the trade name “Chemite CP-05” manufactured by Chemitec can be preferably used. This phosphorescent agent is 30 cm from a 15 W fluorescent lamp.
By irradiating for 10 minutes after being separated, it has an excellent light emitting property that the light emission is continued for 10 hours or more continuously after the irradiation is stopped. In addition, it has a durability of 10 years or more in terms of light energy absorption and light emission in the dark, and since it does not contain radioactive substances or other harmful substances, it does not have an adverse effect on human skin, etc. Since it is not absorbed by the skin of the human body, even if the spectacle frame manufactured using the plate P is worn for a long period of time, there is no problem in safety. Similarly, for the synthetic resin layers 2 and 3, one selected from acetate, propionate, polycarbonate, celluloid and the like can be preferably used.

When the thickness of each plate P described in FIGS. 1 to 8 is set to about 3 mm to 3.5 mm, the original shape of the eyeglass frame can be formed by punching out the plate P. Then, the synthetic resin plate P of FIG. 1 and FIG.
In the synthetic resin block 1 contained therein, square pellets obtained by crushing an extruded synthetic resin sheet having a thickness of 3.5 mm or more, for example, a thickness of 4 mm can be suitably used. In the resin plate P, the synthetic resin block 1 contained therein is extruded to have a thickness of 3
Square pellets obtained by crushing a synthetic resin sheet of mm or less can be preferably used. Further, in the synthetic resin plate P shown in FIGS. 4 and 5, the synthetic resin thin layer 4 is made by kneading the above-mentioned “Chemtech CP-05” powder into the synthetic resin. The plate P
The thickness can be set to about 2.0 to 10.0 mm, and by doing so, it becomes possible to manufacture an eyeglass frame having a large thickness and a sense of volume.

The plate P described in FIG. 1 is manufactured by the method shown in FIG. 9, that is, the manufacturing method of the invention according to claim 5. That is, the above “Chemtech CP-0
The above-mentioned synthetic resin in which the powder of "5" is kneaded is extruded into a sheet. The amount of the phosphorescent agent kneaded into the synthetic resin is 5% by weight or less, and even if an amount exceeding this is kneaded,
The improvement of light energy absorption and luminescence in the dark of the final product, the spectacle frame, cannot be expected so much. In the example, the thickness of the sheet is set to 4 mm, and the synthetic resin pellet obtained by crushing the sheet corresponds to the synthetic resin block 1 described above. As described above, this synthetic resin pellet has a square shape (square pellet), and since the original sheet has a thickness of 4 mm, most of the pellets are It has a part longer than 4 mm.

On the other hand, synthetic resin pellets (base material pellets) containing no luminescent agent such as a luminous agent are prepared.
For the base pellets, the same synthetic resin as the synthetic resin forming the synthetic resin block 1 or a synthetic resin compatible with the synthetic resin is used. Since the base material pellet does not contain a phosphorescent agent, it can be obtained at a lower cost than a synthetic resin pellet containing a phosphorescent agent. As the base material pellet, one smaller than the synthetic resin pellet containing the phosphorescent agent can be suitably used.

Next, a mixture of synthetic resin pellets containing a phosphorescent agent and base material pellets is thermocompressed into a plate shape.
That is, when a layer of a mixture of both pellets is pressed by a hot press plate, a plate P having a constant thickness described in FIGS. 1 and 2 is obtained, and in the plate P, a composite containing a base material pellet and a phosphorescent agent is obtained. The resin pellets (synthetic resin block 1) are fused and integrated with each other, and a part of the synthetic resin block 1 is exposed on the surface of the plate P. Here, the thickness of the plate P obtained by thermocompression molding is set to be thinner than the size of the synthetic resin block 1, for example, 3
When it is set to about 3.5 mm, a part of the synthetic resin block 1 is exposed on the surface of the plate P, as can be inferred from FIG.

By punching out the plate P thus obtained, the original shape of the spectacle frame of the invention according to claim 6 is obtained. The original shape of the punched eyeglass frame is a product after undergoing necessary processing steps such as polishing, and the eyeglass frame thus obtained has a sufficient strength required for the eyeglass frame, Moreover, since the synthetic resin block 1 is exposed on the surface, it has a light energy absorbing property and a dark light emitting property.

In the synthetic resin plate P for eyeglass frames described with reference to FIG. 3, synthetic resin pellets corresponding to the synthetic resin mass 1 are, for example, 3.0 mm or less in the above manufacturing method.
It can be manufactured by making the thickness smaller than the thickness (3 to 3.5 mm) of the synthetic resin plate P, and thermocompression molding using transparent pellets as a part of the base material pellets.

In the spectacles A shown in FIG. 10, 21 is a lens frame forming the edge frame of the lens G, and 22 is a temple for hanging on the ear. The eyeglass frame which is the object of the present invention may refer to the lens frame 21 only, the temple 22 only, or both the lens frame 21 and the temple 22, but it is possible to know the location of the eyeglasses in the dark. As described above, the portion having the dark-light emitting property may be a part or the whole of the temple 22 and the lens frame 21. In this specification, the temple 2 or the lens frame 1 will be described as a spectacle frame F.

The spectacle frame F manufactured by the above-described manufacturing method has a luminescent agent contained in the synthetic resin block 1 which absorbs the energy of light of daytime sunlight or fluorescent light and is stimulated by light to generate light. After stopping the supply of energy, that is, after stopping stimulation,
The light is emitted gradually and continues to emit light for a certain period of time. Therefore, even in the dark at night, the location of the spectacles can be known by the light emission, so a situation that tends to occur when searching for spectacles by groping, such as dropping the spectacles from the shelf or trampling the spectacles and breaking it is possible. Disappeared
In the event of an earthquake or other disaster, it will be possible to quickly find the whereabouts of glasses without lighting. And
As a conventional example, it is not the one holding the phosphorescent tape as described above or applying the phosphorescent paint, but the spectacle frame itself has a dark light emission property, so it can be used repeatedly for a long time. Even if the surface of the eyeglasses is worn, the light energy absorption of the spectacle frame and the light emission in the dark are not impaired.

The plate P described with reference to FIGS. 4 and 5 is manufactured by the manufacturing method described below. That is, by simultaneously extruding the synthetic resin in which the powder of “Chemtech CP-05” is kneaded and the synthetic resin containing no luminescent agent at the same time by an extrusion molding die, one surface of the synthetic resin layer 3 containing no luminescent agent or It is formed by integrally equipping both surfaces with a synthetic resin thin layer 4 containing a luminescent agent.

A spectacle frame can also be made by punching out the plate P thus formed.

The synthetic resin plate P for eyeglass frames described with reference to FIGS. 6 and 8 can be manufactured by multi-layer extrusion of a synthetic resin layer 6 containing a luminescent agent and a synthetic resin layer 5 containing no luminescent agent. The synthetic resin plate P for eyeglass frames described with reference to FIG. 7 can be manufactured by laminating and integrating the plate P described with reference to FIG. 6 on a transparent or opaque synthetic resin layer.

Then, the original form of the spectacle frame is manufactured by punching out the synthetic resin plate P for the spectacle frame of FIGS. 6 to 8, and the spectacle frame manufactured in this way has a sufficient size required for the spectacle frame. In addition, the surface of the synthetic resin layer containing a light emitting agent or the end face exposed by punching has a light energy absorbing property and a dark light emitting property.

In the spectacle frame synthetic resin plate P described with reference to FIGS. 1 to 8, the surface thereof may be covered with a transparent layer. In such a case, the transparent layer has a property of transmitting light. There is no effect on the light energy absorbing property or the dark light emitting property of the luminescent agent contained in the synthetic resin block 1, the synthetic resin thin layer 4, or the synthetic resin layer 6. In addition, a coloring agent such as a dye may be kneaded into the synthetic resin of the synthetic resin block 1 containing the base material pellets and the luminescent agent used for manufacturing the synthetic resin plate P for the eyeglass frame described in FIG. In this way, black
Those colored in various colors such as white, yellow, and green are very fashionable because a tortoiseshell pattern appears on the surface of the eyeglass frame when the eyeglass frame is punched out.

Since it is contained only in the places where it is present, even if the amount of the luminescent agent in those places is increased to exert sufficient luminescent performance, the amount of the luminescent agent occupying the whole plate is small, Even if the luminescent agent itself is expensive, the price of the plate itself is not so high.

Then, the eyeglass frame according to the invention according to claim 6, claim 7, claim 8 or claim 9 manufactured by punching out these plates has a surface whose surface has a sufficient light emitting performance partially or wholly.
