Technical Field

The present _, invention relates to a rim of a pair of glasses, and more particularly, to a pair of rimless glasses without having the rim fixing spectacle glasses .

Background Art

Generally, a pair of glasses has spectacle glasses which are lenses and a rim fixing the spectacle glasses . The pair of glasses is classified into a pair of rim glasses in which the rim is formed of a horn rim made of synthetic resin, or a metal band made of metal and a pair of rimless glasses uniting a nose support and legs with spectacle glasses . The pair of rim glasses includes a body rim and legs in which grooves fixing the spectacle glasses are formed in both sides of the body rim as a symmetrical structure, and the legs are formed in both sides of the body rim so as to be hooked up the rim of the external ear. The pair of rimless glasses includes a nose support with which glasses are connected at both sides thereof, and legs connected to the outer side of each spectacle glasses so as to be hooked up the rim of the external ear .

The pair of rim glasses has a defect that a rim of glasses

comes into a field of vision when a user wears a pair of rim glasses . Also, the pair of rim glasses affects on the personal appearance of a wearer by the color or shape of the glass rim. Accordingly, wearers should carefully choose a rim of rim glasses . The pair of rimless glasses has a merit that a rim of glasses does not come into a field of vision when a user wears a pair of rimless glasses . Also, the pair of rimless glasses does not affect on the personal appearance of a wearer since there is no rim of glasses . Accordingly, many wearers favorably select pairs of rimless glasses .

However, in the case of the pair of rimless glasses, holes should be formed on both sides of the glasses and then a nose support and legs should be combined on the holes formed on the glasses by means of screws, in order to fix the nose support connecting glasses and the legs with which the pair of the rimless glasses can be hooked up the rim of the external ear to the holes of the glasses . Accordingly, since the connection portions of the glasses, in particular, the portions where the legs are connected on the holes of the glasses are in a field of vision of wearers, a comfortable feeling of wearing of the glasses is lowered.

In addition, in the case of the rimless glasses, since the nose support and the legs are united with screws on the spectacle lens, a comfortable feeling of wearing of the glasses is lowered, the glasses may slip down, focuses of the glasses mismatch to cause

the eyesight to go bad, and the glasses may be damaged, if the screws are loosened after long-time lapse or due to external impact.

Further, it is very inconvenient for wearers to wash the glasses due to the protruded screws. Since every nook and corner of the glasses is not cleaned well, it may be messy and dirty. Also, various kinds of harmful bacteria may inhabit in the connection portions of the glasses, to thereby cause insanitation and externally smutty appearance.

Disclosure of the Invention

To solve the above problems, it is an object of the present invention to provide a pair of rimless glasses on the lateral surfaces of which fixing grooves of a certain depth are respectively formed in which one side of a nose support and one of legs are united with one fixing groove and the other side of a nose support and the other side of legs are united with the other fixing groove, by means of a fixing pin and a support unit, to thereby make the glasses firmly fixed to the nose support and the legs, and cause a comfortable feeling of wearing of the glasses to increase since the connection portions of the glasses is out of a field of vision of a wearer.

Best Mode for Carrying out the Invention

Hereinbelow, a pair of rimless glasses according to the present invention will be described with reference to the accompanying drawings .

Referring to FIG. 1, a pair of rimless glasses 1 includes

two spectacle glasses 10 as a pair having fixing grooves 11 of a certain depth on both sides thereof, and legs 30 and a nose support 20 on each of which a fixing pin 40 which is inserted into each fixing groove 11, and a support pin which is formed in parallel with the fixing pin and at an acute angle with respect to the fixing pin are formed.

The fixing grooves 11 formed in the spectacle glasses 10 have a predetermined depth with a rectangular or circular shape.

The fixing pin 40 and the support pin 50 formed in each leg 30 are formed at the right angle with respect to the leg 30, and the fixing pin 40 and the support pin 50 are formed in both sides of the nose support 20 in parallel with each other.

The fixing pin 40 and the support pin 50 are formed in parallel with each other, with a little wider gap (see Figure 3 or 5) or with a little smaller gap (see Figure 4) .

The fixing pin 40 and the support pin 50 formed in each leg 30 or the nose support 20 have different lengths . Here, the fixing pin 40 is longer than the support pin 50, in which the ratio is preferably 1.5 : 1 to 2 : 1. Referring to Figure 4, as an alternative embodiment of the present invention, support grooves 60 into which the support pins 50 are inserted are formed at the rear sides of the fixing grooves 11 formed in the spectacle glasses 10, respectively.

Also, referring to Figure 5, as another alternative

embodiment of the present invention, the fixing pin 40 has a locking stop 41. Accordingly, the fixing pin 40 is easily inserted into and hardly separated from the fixing groove 11.

An assembly sequence of the rimless glasses 1 according to the preferred embodiments of the present invention as constructed above will be described below.

Firstly, fixing grooves 11 are formed on the upper part of both sides of spectacle glasses 10 into a certain depth. The shape of the fixing groove 11 is formed in the same shape as that of the fixing pin 40, as a circular or rectangular shape . The hole size of the fixing groove 11 is formed identically to or a little smaller than the thickness of the fixing pin 40.

When the fixing grooves 11 are completely formed in the spectacle glasses 10, the fixing pin 40 which is formed at one side of the nose support 20 is inserted into one fixing groove 11 formed at one side of the spectacle glasses 10. The other fixing pin 40 which is formed at the other side of the nose support 20 is inserted into the other fixing groove 11 formed at the other side of the spectacle glasses 10. ' Thereafter, the legs 30 are united with both sides of the glasses 10. Here, the legs 30 are combined with the spectacle glasses 10 in the same manner as that the nose support 20 is combined with the spectacle glasses 10.

The support pin 50 positioned at the rear side of the fixing

pin 40 is positioned at the back of the spectacle glasses 10, in order to support the fixing pin 40, as shown in Figure 3. Accordingly, the fixing pin 40 is prevented from being separated from the fixing groove 11. Moreover, the size of the fix groove 11 is identical to or a little smaller than the thickness of the fixing pin 40. Accordingly, the fixing pin 40 is suppressively fitted with the fixing groove 11, to thereby prevent the former from being separated from the latter . Also, since the fixing pin 40 and the support pin 50 are formed in parallel with each other, with a little wider gap (see Figure 3 or 5) or with a little smaller gap (see Figure 4) , the fixing pin 40 and the support pin 50 fix the glasses 10 as if a crab bit an obj ect . Since the fixing pin 40 is formed longer than the support pin 50, the glasses 10 are prevented from being separated from the fixing grooves 11 when external impact occurs in a pair of the glasses 1. That is, the support pin 50 gives a support force to the fixing pin 40. As another embodiment of the present invention, as shown in FIG. 5, a support groove 60 is formed at the rear side of each glass 10 at the same position as that where the fixing groove 11 is formed. In this manner, when the support pin 50 is positioned into the support groove 60, the glasses 10 can be more adamantly

fixed to the nose support 20 and the legs 30.

Moreover, a locking protrusion 41 is formed in the fixing pin 40, in the direction of inserting the fixing pin 40. Thus, when the fixing pin 40 is inserted into the fixing groove 11, the former is easily inserted into the latter and the former is hardly seceded from the latter .

Therefore, when putting on a pair of the glasses 1 , the nose support 20 is positioned in the middle of the forehead, that is, the brow. Accordingly, since the nose support 20 is not in a field of vision of a wearer, the connection portions of connecting the spectacle glasses 10 and the legs 30 are positioned at the sides of the glasses 10. Accordingly, since the connection portions of connecting the spectacle glasses 10 and the legs 30 are not in a field of vision of a wearer, the feeling of wearing is improved. Moreover, as described above, since the spectacle glasses 10, the nose support 20 and the legs 30 are not connected by means of screws, the conventional problems such as movement of the glasses 10 which may be caused by the screws loosened can be prevented. Also, with no protruding screws, the whole glasses can be cleaned when washing the glasses, to thereby provide a clean and sanitary use .

As described above, a pair of rimless glasses according to the present invention improves the feeling of wearing and solves a problem of movement of glasses due to a long-time use,

in which fixing pins formed in a nose support or legs are inserted into fixing grooves formed at the sides of glasses to thereby enable a simple combination of the fixing pins with the fixing grooves, and connection portions of the glasses and the legs are not in a field of vision of a wearer .

Also, since the glasses are not fixed by screws, and thus there are no protruding portions in the glasses, the whole of the glasses can be cleaned. Also, the weight of the pair of glasses can be reduced by those of the screws . Also, the assembly of the glasses with the legs and the nose support is easily done .

As described above, the present invention has been described with respect to particularly preferred embodiments . However, the present invention is not limited to the above embodiments, and it is possible for one who has an ordinary skill in the art to make various modifications and variations, without departing off the spirit of the present invention. Thus, the protective scope of the present invention is not defined within the detailed description thereof but is defined by the claims to be described later and the technical spirit of the present invention.

Industrial Applicability

As described above, the present invention provides a pair of rimless glasses on the lateral surfaces of which fixing grooves of a certain depth are respectively formed in which one side of

a nose support and one of legs are united with one fixing groove and the other side of a nose support and the other side of legs are united with the other fixing groove, by means of a fixing pin and a support unit, to thereby make the glasses firmly fixed to the nose support and the legs, and cause a comfortable feeling of wearing of the glasses to increase since the connection portions of the glasses is out of a field of vision of a wearer.
