DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to front recessed glasses, more specifically, a rim portion of a front frame sinks into the periphery of left and right lenses to hold the lens firmly, and the rim is almost completely visible in appearance. Not for rimless style front recessed glasses.

[0002]

2. Description of the Related Art A through hole is formed in a bridge side and a temple side of a pair of left and right lenses. A screw rod protruding from both ends of the bridge is inserted into the through hole on the bridge side, and a nut is fastened to the temple side. Each of the end piece parts is inserted with a threaded rod and similarly fastened with a nut. Glasses formed by pivotally supporting a temple on each of these end pieces are so-called "two-point rimless glasses (hereinafter, referred to as" two-point type rimless glasses "). It is widely known in the past as "two-point glasses"), and has become very popular in recent years because it is light in design and lightweight and has a wide field of view.

However, this type of two-point glasses adopts a system in which a lens, a bridge, and an end piece are fixed to a through hole formed in the lens by a bolt and nut mechanism by a point support system. Bolt heads and nuts that can protrude toward the eyepiece from the eye are very obstructive to nervous wearers, and the through holes are worn out due to the external force of the bridge and end pieces that are frequently repeated during use. However, there is a drawback that the size becomes large and play (rickety) easily occurs.

Also, in the conventional two-point glasses, when assembling, a through hole of an accurate size is drilled at the position where the lens is fastened without deviation, and then the bridge and the end piece threaded rods are inserted to fix the nut. Some complained that the work was extremely troublesome and inefficient because they had to do it.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks and dissatisfaction despite the fact that conventional two-point glasses are popular with modern people. Provide smart, practical front-embedded glasses that have a rimless spectacle-like appearance, have no through-holes in the lens, and have a structure that keeps the lens firm and does not rattle over time. This is a technical issue.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.

[First Embodiment] In FIGS. 1 to 5, what is indicated by reference numeral 1 is a lens used for front embedded glasses (hereinafter, referred to as a first embodiment product) according to a first embodiment of the present invention. A rim portion of the front frame, which will be described later, is just buried in the peripheral edge, and a fitting groove 11 having a width and a depth that cannot be seen from the front is carved all around.

Next, a reference numeral 2 designates a front frame made of a nickel-titanium superelastic alloy wire, and a rim for holding the lens 1 side by side.
21 ・ 21, overhanging ears 22 ・ 22 formed by bending the constituent wires outward from the left and right rims 21 ・ 21 in a hook shape, and the right and left rims 21
And a bridge 23 for connecting the and 21 in a cross-linked manner. The rims 21 of the front frame 2 are fitted into the fitting grooves 11 carved in the lens 1.1 to close the protruding ears 22 and 22 so that the lenses are arranged side by side in a symmetrical state. Can be held in In the first embodiment, the bridge 23 is formed by bending a white wire, and snake-shaped pad arms 24 are formed at both ends so as to bend in the nose direction and extend. At the lower ends of both pad arms 24, nose pads 25 made of silicone rubber are respectively mounted.

The reference numeral 3 designates a crossing end piece having an end welded to an overhanging ear 22 formed on each of the left and right outer sides of the front frame 2.
ece), and the end piece 3 is composed of a pair of upper and lower couple plates 31 and 31 and a stay stopper 32 fixed to the lower surface of the upper end of the upper couple plate 31 at the take-out end. A pivot hole 33 for screwing and pivoting a pivot described later is formed by penetrating the upper and lower plates 31.

The one designated by reference numeral 4 is a temple, and has a ring-shaped piece 41 at the base end. The temple 4 is hingedly connected to the crossing end pieces 3 welded to the left and right ends of the front frame 2, respectively. In the present embodiment, the piece 41 of the temple 4 is placed inside. From the upper and lower couple plates 31 constituting the crossing end piece 3 so that the frame hole of the temple piece 41 is aligned with the pivot hole 33 of the end piece and the pivot 5 is screwed. The temples are hingedly connected to the left and right sides of the front frame 1. The temples 4.4 of the first embodiment thus assembled.
Is rotatable within an angle range until it comes into contact with the folding position and the stay stopper 32. The hinge connecting operation of the crossing end piece 3 by the pivot 5 allows the rim 21 fitted in the fitting groove 11 to elastically tighten the peripheral edge of the lens 1, thereby maintaining the appearance of rimless spectacles and the left and right lenses. The function of stably maintaining 1.1 is exhibited.

[Second Embodiment Product] A second embodiment product of the present invention is shown in FIG. 4 and FIG. The second embodiment differs from the first embodiment in the structure of the crossing end piece 3 and the manner in which the temple 4 is hinged.

That is, in the product of the second embodiment, the stay stopper 32 is located at a substantially intermediate position between the upper and lower couple plates 31 constituting the crossing end piece 3 and the lower surface of the upper couple plate 3. The pivot hole 33 to which the pivot 5 is screwed and pivoted is formed by drilling near the projecting end of the crossing end piece 3. When the temple 4 narrows the piece 41 formed inside the base end thereof into the protruding end of the crossing end piece 3 and aligns the piece hole with the pivot hole 33 and screw-in the pivot 5, The left and right temples 4 are the pieces
When the distal end extending from 41 abuts against the stay / stopper 32 from the outside during the expanding operation, the angle of the expansion is regulated. In this case as well, the pivot 5
The rim 21 fitted in the fitting groove 11 also elastically tightens the peripheral edge of the lens 1 to maintain the appearance of rimless glasses and stabilizes the left and right lenses 1.1. Demonstrate the function to hold.

Although the embodiments of the present invention specifically disclosed in the present specification are generally configured as described above, the present invention is not limited to the above-described embodiment products, and is not limited thereto. Various material substitutions and design changes are possible within the description.

For example, the protruding ear portions 22 provided on the left and right sides of the front frame 2 are formed in a hook-shaped bent shape in the above-described embodiment, but the elasticity is enhanced and the decoration is provided. It is also possible to make a snake-like curve to enhance the effect.

[0017]

As described above, in the front recessed glasses according to the present invention, the rim portion of the front frame is elastically and stably held in a state where the rim portion is fitted in the fitting grooves of the left and right lenses. So, while having a clean rimless glasses-like appearance, there is no through hole in the lens,
In addition, since the lens is held firmly and does not rattle with the lapse of time, it has both design and practicality.

As described above, according to the present invention, it is possible to realize front-embedded spectacles which do not project an unsightly bolt and nut mechanism that obstructs the field of view while exhibiting a rimless spectacle-like design at all on the lens surface. Is extremely simple and inexpensive to manufacture, has good lens holding stability, and is extremely valuable in industrial applications.
