Description

"MULTIPLE SETTINGS FOR SUNGLASSES"

Field of invention

[001] The object of the present invention patent is a practical and innovative frame for glasses with multiple adjustments, belonging to the field of articles for optics, finds applications in the construction of glasses with ametropia compensation lenses or simply spectral filters, whose technology allows to adjust the dimensional parameters for any human biotype, with simplicity and practicality.

[002] It is an eyeglass frame with all adjustable variables, such as the size of the rods, distance between the lenses, etc., made from standardized components, which allows a substantial reduction in the cost of production.

[003] There is, therefore, in the patent application in question, an orthosis specially designed and developed to obtain enormous practicality and which brings great advantages, both in its use and in its manufacture.

State of the art

[004] As is well known, several models of frames with adjustments for glasses are already known from the state of the art.

[005] In this aspect and in the sense of specifying the state of the art, some patent documents can be cited that deal with frames with adjustments, but without achieving the inventive merit and the differences now revealed, as follows below.

[006] US patent document 6986576 B2, entitled "DEFORMABLE LENS FOR ADJUSTABLE GLASSES"; reveals glasses, including a frame containing deformable lenses within the frame, the frame including means for deforming the lenses or changing the focal length of the lenses to increase the wearer's ability to see clearly.

[007] US patent document 2,622,477, entitled "ADJUSTABLE NOSE BRIDGE SUPPORT FOR BIFOCAL LENSES"; refers to ophthalmic mountings and consists of an improved mount or bracket that is a permanent part of the frame mount, for use with bifocal or trifocal lenses and the like.

[008] US patent document 2017/0068109 A, entitled "COVER WITH ADJUSTABLE LENS HEIGHT"; includes a lens frame, a first lens unit and an adjustment unit. The first lens unit is arranged in the lens structure and includes a plurality of lenses that are aligned, in the direction, from front to back. At least one of the lenses is movable in relation to the lens frame and has a plurality of correction zones. The correction zones have different curves and are arranged in a top to bottom direction. The adjustment unit is arranged in the lens frame and is operable to move the movable lens towards the top of the bottom in relation to the lens frame.

[009] US patent document 2014/0247422 A1; entitled "ADJUSTABLE FOCUS LENS WITH DOUBLE UNILATERAL PERFORMANCE"; reveals an adjustable focus lens where the adjustment range can be moved. That is, if a pair of adjustable focus glasses has a range of 0 diopters for 2.75 diopters (to provide an addition for reading an emetrope), this invention could, for example, allow the user to move the range from 0 D to 2.75D, to 2.00D, to 4.75D, in order to accommodate a rapid change in the user's vision range. Each eye can be adjusted independently.

[010] US patent document 6698882 B, entitled "ADJUSTABLE LENSES FOR INTEROCULAR DISTANCE" refers to a pair of adjustable displays to adjust the interocular distance, on which a frame integrally connected between the two regular eyeglass frames is designed so that the distance between the two eyeglass frames of the mount is adjustable or replaceable. After the glasses frame is manufactured and shipped outside the factory, the user can quickly and easily adjust the interocular distance and assemble the glasses. The present invention can reduce the manufacturer's inventory, adjust the mass production requirement and greatly reduce the cost.

[01 1] US patent document 6698882 B, entitled "SUNGLASSES WITH REMOVABLE LENSES, SIDE BARS AND ADJUSTABLE HEADSETS"; refers to glasses and / or sunglasses with a single metal or plastic frame and a plurality of interchangeable, removable or replaceable lenses, temple side bars, temple ornaments, lenses with colored beads and adjustable to the ear. Lenses of different colors and shapes are attached magnetically to the frame. Temple side bars and ornaments of different colors and shapes are attached to the frame.

[012] Patent document ES2213980T3, entitled "FOLDING FRAME GLASSES WITH ADJUSTABLE RODS IN LENGTH "; reveals a folding glasses with telescopic rods and central pivoting bridge. The rods are shown with three or four telescopic elements. The temple of four elements has a distal element that is preformed from material that has a memory , which when curved and extended around the user’s ear and when the elements are telescoped together can be straightened for insertion into the adjacent straight telescopic element. Two ways of bridge articulation are shown, one has an inclined articulation pin and the other has a spring-hinged section in which the adjacent hinge elements are vertically and horizontally translatable against the spring slope when the frame elements are folded for non-use.

Deficient points of the state of the art

[013] The major drawback of the glasses models found on the market so far is the fact that independent of the designs, they are designed in defined sizes and do not allow adjustments, in addition to adapting the curvature of the ear buds to the user's profile.

[014] There are some models that allow longitudinal adjustment of the stem, but only allow a fine adjustment, making it impossible for the same size or frame model to be configured for use by children and adults.

[015] In the usual way, eyeglass frames are manufactured in different sizes and different designs not only to suit the taste of each user, but also to suit different biotypes, genders and especially different ages, such as children and adults. [016] What is observed in the traditional form of eyeglass frames is that their parts are exclusive to each model and this makes the cost of production quite high.

[017] Another drawback to be pointed out is the lack of spare parts for a particular model of glasses, especially because there is no interest in this solution on the part of the sector's traders.

[018] It is thus understood that state-of-the-art spectacle frames have a substantial cost, making it difficult for the low-income population to acquire these orthoses.

Proposed solution

[019] It was thinking about these inconveniences that, after numerous researches and studies, the inventor, a person related to the branch, created and developed the object of the present patent, devising an eyeglass frame with multiple adjustments in which not only the mechanical and functional qualities were considered in the design of its manufacture, but also the shape, layout and location of its parts and components, which, correctly positioned, brought an increase in efficiency without causing any burden.

[020] Thus, the present patent was designed to obtain an orthosis with as few parts as possible, conveniently configured and arranged to allow the glasses frame with multiple adjustments to perform its functions with unmatched efficiency and versatility, without the inconveniences already mentioned.

[021] This patent application presents a practical and innovative frame for glasses with multiple adjustments with all aesthetic and functional qualities, designed and developed according to the most modern techniques, thus enabling its most varied use, from the use by young children to its use by adults of any age.

[022] Its innovative format allows to obtain an excellent level of functionality, offering a frame for glasses with multiple adjustments, which has great durability, having been created, mainly, to present a low cost of manufacture and to be able to be adjusted for users of any age and size.

[023] The configuration of the orthosis, object of the present patent, in its new constructive form, comprises a frame conformed by standardized parts that are joined by fitting and screwing technique at predefined points that make it possible to assemble its structure with substantial ease and adjust all the size parameters for the respective user's biotype.

[024] It is understood that the orthosis in question is extremely simple in its constructiveness, being, therefore, easily feasible, however, excellent practical and functional results are obtained, offering an innovative constructivity on known products.

[025] Idealized with an innovative design, it results in a harmonic set, with a very peculiar aspect and, above all, characteristic, and in addition to the constructive aspect, the product stands out for its versatility and convenience of use and substantial reduction in the cost of production. .

Detailed description of the invention

[035] In accordance with what they illustrate the figures listed above, the "MULTIPLE ADJUSTMENT SUNGLASSES", object of this patent, are essentially characterized by being made up of a structure that allows the adjustment of the dimensional parameters for the biotype of any human being, regardless of gender, age , etc.

[036] More specifically, the glasses frame with multiple adjustments (1) allows the adjustment of the total distance between the rods (defines the width of the frame), the adjustment of the positioning and the distance between the rim of the lens and the adjustment of the length the ear buds.

[037] Said glasses frame with multiple adjustments (1) is constituted from a frontal cylindrical segment (2) provided in its median portion with a trapezoidal projection (3) downwards, where the platelets (4) are attached, being that the outermost portions have a plurality of internally threaded vertical circular holes (5) distributed at regular distances.

[038] The cylindrical frontal segment (2) has two lens rings (6) with positioning adjustments and a graduation in millimeters in order to regulate the interpupillary distance between the user's two eyes. Said lens rim (6) has in its upper portion a rectangular prismatic element (7), which has a vertical hole (9) and a lateral hole (8) through which the frontal cylindrical segment (2) passes, adjusting the lens rings (6) at the pupillary center of each eye.

[039] More precisely, each side of the frontal cylindrical segment (2) receives a lens ring (6), which is positioned in the appropriate place for the user, so that the vertical hole (9) is in a position coinciding with one of the holes vertical (5), and a screw (10) that passes through the orifice (9) is threaded into the orifice (5), effecting the fixation of the respective lens rim (6) in said front cylindrical segment (2).

[040] At the ends of the frontal cylindrical segment (2), the hinge terminals are coupled, which consist of a prismatic rectangular structure (11) of substantial length, the outer sides of which are provided with hinges (12). Said rectangular prismatic structure (1 1) has a longitudinal tunnel (14) and an orifice (13) in its upper face close to the inner end that has the purpose of regulating the distance between the two rods, allowing adjustment to different diameters of the head of a human being and can be used from childhood to adulthood.

[041] The hinge terminals are fitted to the front cylindrical segment (2) so that one of the holes (5) matches the hole (13) and a screw is inserted into that hole and threaded into the hole (5).

[042] The positions of the hinge terminals and the lens rims (6) can be adjusted along the frontal cylindrical segment (2), adjusting them to the pupil center of each eye and the graduation of the interpupillary distance.

[043] The hinge (12) receives a telescopic stem (16) consisting of a rectangular prismatic element (15) within which a rod (17) slides which has a rectangular end with circular holes and at the other a curvature for auricular insertion , which is properly positioned, to the user, and locked by a screw (10) with the function of adjusting the distance between the forehead and the auricular insertion.

[044] Said telescopic rod (16) is coupled on the hinge by means of the rectangular prismatic element (15), whose upper face is provided with a series of circular holes (18) distributed evenly throughout its structure.

[045] The front end of the rod has a hole (19) which must coincide with one of the holes (18) of the rectangular prismatic element (15) and locked by means of a screw (10).

[046] It is true that when the present invention is put into practice, modifications may be made with regard to certain details of construction and shape, without this implying departing from the fundamental principles that are clearly substantiated in the claim framework, becoming thus understood that the terminology used was for the purpose of description and not of limitation.
