Description

Technical Field

[0001] This utility model relates to a one-piece manufactured part for eyeglasses or visors.

[0002] This invention further relates to a method for manufacturing the aforementioned eyeglasses or visor parts.

[0003] More specifically, this invention relates to eyeglasses or visor parts that provide a single element, which includes at least a frame, lenses and possibly nose pads, a hinge point extending to the temples, and the hinge itself. Background Technology

[0004] In the following text, reference will generally be made to eyeglasses, but it should be understood that the same considerations apply to visors.

[0005] Solutions for manufacturing one-piece eyeglasses or visor parts are known in the art.

[0006] However, none of the solutions described allow for the desired results because they do not allow for the manufacture of one-piece eyeglasses or visor components, including lenses, nose pads, and the frame itself.

[0007] Some of these solutions are described in patents US3526449 and EP3399365, but none of them can solve the problem.

[0008] More generally, one-piece manufactured eyeglasses or visors with front frames (where lenses are subsequently added), or one-piece manufactured front frame assemblies and lenses (with nose pads and / or bridges subsequently added to these front frame assemblies and lenses) are known in the art.

[0009] One-piece masking (e.g., Oakley Kato) is still known in the art, in which other components (such as temples and / or nose pads made of rubber or plastic materials) are subsequently added to the mask.

[0010] Furthermore, eyeglasses, particularly those intended for children, are known to have frames that are entirely one-piece and made from a single material (e.g., rubber), with lenses subsequently added to the frame. These eyeglasses, made from highly flexible materials, fail to meet the strength and stability requirements necessary for everyday general-purpose eyeglasses and / or visors (especially adult models). Utility Model Content

[0011] According to this utility model, these and other problems are addressed and solved, and a solution is proposed for making the parts of eyeglasses or visors (including lenses, nose bridge and / or nose pads, as well as hinges and articulation elements) into a one-piece form, which can meet the strength and stability requirements necessary for everyday general-purpose eyeglasses and / or visors (especially adult models).

[0012] According to the present invention, a one-piece eyeglass or visor part is provided, characterized in that the part is made of a single material of biopolymer or plastic material, all parts of the eyeglass or visor are made of the same material, the part includes a lens, and / or a nose pad or nose pad component, an end piece for connecting the temple, a bridge, a front frame of the eyeglass or visor, a hinge and / or a hinge element, and wherein continuous regions of different thicknesses are provided, the size of the continuous regions being determined such that the maximum thickness difference between the region with higher thickness and the region with lower thickness is between 1.5 mm and 6 mm, the continuous regions being connected by a connecting portion with a radius of curvature between 0.5 mm and 5 mm.

[0013] Alternatively, the part is a part manufactured by a single injection molding step.

[0014] Optionally, the plastic material belongs to the category of biopolymers, thermoset polymers, or thermoplastic polymers, and has the lowest possible crystallinity to ensure the transparency and optical quality of the molded product.

[0015] Alternatively, the part is a part manufactured by a casting process.

[0016] Optionally, the thickness difference between the region with higher thickness and the region with lower thickness is 2 mm.

[0017] Optionally, the radius of curvature of the connecting portion is equal to 0.5 mm.

[0018] Optionally, the lens is functionalized.

[0019] Optionally, the functionalization provides a polarization layer.

[0020] Optionally, the parts of the glasses or visor are treated.

[0021] Optionally, the parts of the glasses or visor are subjected to anti-reflective treatment, mirror treatment, anti-fog or anti-condensation treatment, hydrophobic treatment and / or anti-fouling treatment, scratch-resistant treatment, and / or antistatic treatment.

[0022] Optionally, the lens is an ophthalmic lens.

[0023] A method is also provided for manufacturing a one-piece part for eyeglasses or a visor, the part being made of a single biopolymer or plastic material, all parts of the eyeglasses or visor being made of the same material, the part including lenses, and / or nose pads or nose pad components, end pieces for connecting temples, a bridge, a front frame of the eyeglasses or visor, hinges and / or articulating elements, wherein continuous regions of different thicknesses are provided in the method of manufacturing the part of the eyeglasses or visor, the size of the continuous regions being determined such that the maximum thickness difference between the region with higher thickness and the region with lower thickness is between 1.5 mm and 6 mm, the continuous regions being connected by connectors with a radius of curvature between 0.5 mm and 5 mm.

[0024] The method provides a way to manufacture the glasses or visor as a one-piece part through a single injection molding step or through a casting process.

[0025] The difference between the region with higher thickness and the region with lower thickness is 2 mm.

[0026] The radius of curvature of the connecting region is equal to 0.5 mm.

[0027] The lens undergoes functionalization.

[0028] The functionalization provides a polarization layer.

[0029] The parts of the eyeglasses or visors are treated, in particular, with anti-reflective treatment, mirror finish, anti-fog or anti-condensation treatment, hydrophobic treatment and / or anti-fouling treatment, scratch-resistant treatment, antistatic treatment and / or other types of treatment.

[0030] The lens in question is an ophthalmic lens. Attached Figure Description

[0041] In particular, by observing the appendix Figure 1 To be continued Figure 9 The diagram shows the glasses generally indicated by reference numeral 1 in the attached figure. Figures 7 to 9 The glasses are made entirely of parts 10 manufactured by injection molding. Figures 1 to 6 ).

[0042] All parts 10 of the eyeglasses 1 are injection molded into preferred shapes, including the lenses 2.

[0043] Therefore, in the step of producing part 10 of the one-piece eyeglasses 1 and through a single molding step, the nose pad or nose pad component 3, the end piece 4 for connecting the temple (not shown), the bridge 5 and the entire front frame 6 of the frame, and the hinge 7 itself and / or the hinge element 7 are also produced.

[0044] The hinge 7 and / or hinge element 7 refers to both the temple / frame connecting element and the corresponding seat 71. Specifically, preferably, the eyeglass or visor component 10 includes the hinge element 7, such as the seat 71 formed particularly in each end piece 4, into which hinge components are adapted to be inserted. For example, the seat 71 is adapted to receive a hinge screw or other element, which may be made of the same or even different material as the eyeglass or visor component 10 and is attached to the eyeglass or visor component 10 after the component 10 itself is manufactured. The temple / frame connecting element and the corresponding seat 71 may be made of plastic or metal. The aforementioned elements can be combined with each other in all possibilities, i.e., metal-metal, plastic-metal, metal-plastic, plastic-plastic.

[0045] According to the method of this invention, the method allows for the acquisition of parts 10 of eyeglasses 1, which are presented as having all elements 2-7 in one piece and are made by a single molding process. The method is characterized by a specific combination of material thickness in relevant areas of different parts, and is also used to produce aesthetic effects (such as hue) and / or to give the final object a particularly pleasing shape.

[0046] In an alternative embodiment, the part 10 of the eyeglasses 1 is made by casting. The material is cast by gravity in a special mold, rather than by injection.

[0047] According to this invention, a single material can be used, a feature that allows for greater environmental sustainability due to the increased possibility of recycling at the end of its lifespan and the elimination of components and / or additional parts.

[0048] The temples 8 of the eyeglasses 1 are connected by hinges 7 after being made into a one-piece part 10.

[0049] This further resulted in a significant reduction in production waste from manufacturing finished eyeglasses and a substantial decrease in the final weight of the object.

[0050] Furthermore, this method can also impart additional features (e.g., functionalization) to the glasses 1. In a polarized embodiment, the lens 2 of the glasses 1 is functionalized, for example, by including a polarizing layer.

[0051] Several treatments may be applied to the lens 2 of the eyeglasses 1 for illustrative but not exhaustive purposes, such as anti-reflective treatment, mirror treatment, anti-fog or anti-condensation treatment, hydrophobic treatment and / or anti-fouling treatment, scratch-resistant treatment, anti-static treatment, and other treatments known in the prior art. These treatments may be applied to the outer surface (facing away from the wearer's eyes) and / or the inner surface (facing the wearer's eyes) of the lens 2 of the eyeglasses 1.

[0052] According to this invention, a two-dimensional / three-dimensional object can be encapsulated within one or more lenses 2. Specifically, one or more lenses 2 may optionally include one or more two-dimensional or three-dimensional objects encapsulated therein, the one or more of which are made of a material different from the material used to make the parts 10 of the glasses or visor.

[0053] According to this invention, a functionalized layer made of a material different from the material used to make the eyeglasses or visor part 10 can be laminated into the eyeglasses or visor part 10. According to this technique, one or more additional layers are applied to the inner or outer surface of the eyeglasses or visor part 10 by a combination of heat and pressure, and the possible introduction of an adhesive layer.

[0054] The glasses 1 or mask can preferably be made in a single color. Gradient coloring effects can be produced by adjusting the thickness and / or by coloring techniques known in the art (e.g., by immersion or dipping).

[0055] According to this invention, one or more decorative elements may be further associated with the part 10 of the eyeglasses or visor. In particular, the decorative elements are attached to the part of the eyeglasses or visor after it has been made into the part 10 of the eyeglasses or visor. For example, the finished eyeglasses 1 may include one or more decorative elements glued to the lens 2 or the front frame 6.

[0056] With particular reference to the aforementioned thickness, the molded eyeglasses 1 provides continuous regions with different thicknesses, the size of which must be determined such that the maximum thickness difference between the region with higher thickness and the region with lower thickness is between 1.5 mm and 6 mm, preferably 2 mm.

[0057] The continuous regions must be connected by a connecting portion with a radius of curvature between 0.5 mm and 5 mm, preferably 0.5 mm.

[0058] The design and size of this combination of thickness and radius of curvature were determined to give the aforementioned aesthetic effect, while ensuring the product's manufacturability and preventing defects associated with the functionalization process carried out through immersion.

[0059] Regarding the materials, the eyeglasses 1 or shield according to this invention are made of plastic materials, particularly plastic materials belonging to the category of thermoplastic or thermosetting polymers, preferably thermoplastic polymers, which have the lowest possible crystallinity in order to ensure the transparency and optical quality of the molded product.

[0060] Alternatively, the same object can be made from biopolymers to further highlight the product's sustainability profile.

[0061] Eyeglasses 1 or a mask can still be manufactured by the method according to this invention, thereby imparting the typical characteristics of ophthalmic lenses to the field of optics.

[0062] The present invention has been described for illustrative and not restrictive purposes according to preferred embodiments, but it should be understood that changes and / or modifications can be made by those skilled in the art without departing from the relevant scope of protection defined in the appended claims.
