Field of the Invention The present invention relates to eyeglasses. More particularly, the present invention relates to a pair of glasses having a nose-gripless frame. The pair of glasses of the present invention is worn with a pair of ear-grips and a pair of side fixing devices, but not with a pair of nose-grips on the frame. The present invention also includes a pair of eyeglasses assembled with a nose-gripless frame.

Background of the Invention

Conventional eyeglasses have a pair of nose-grips on the frame of the eyeglasses, which is contacted on the ridge of the nose of awearer. A pair of eyeglasses is worn with both a pair of ear-grips at the end of the frame of eyeglasses and a pair of nose-grips formed on the frame at the ridge of the nose.

The conventional eyeglasses having a pair of nose- rips have various shortcomings when a person wears them. The weight of the eyeglasses including the lens concentrates on the nose-grips and applies to the ridge of the nose of a wearer. Some wearers feel a kind of stress on the nose due to the weight of eyeglasses through nose-grips when they wear a pair of glasses. Also, some wearers feel tired andhave a headache due to the stress. When wearing the conventional glasses having a pair of nose-grips, the traces of the nose-grips occur on the ridge of the nose. In particular, female wearers do not like the traces on the nose, and avoid wearing a pair of conventional glasses. When a wearer sweats on his face, the eyeglasses is slided downward. Therefore, the wearer repeats putting the eyeglasses up.

Accordingly, there have been some efforts and developments

to invent a nose-gripless frame of a pair of eyeglasses. As shown in Fig. 2, Korean Utility Model Application No. 92-18852 discloses a nose-gripless frame for eyeglasses. While the frame does not have a pair of nose-grips, it has a pair of fixing members on a position of the rim so that both the ear-grips at the end of the rim and the fixing members may support the pair of glasses. However, the nose-gripless frame does not have good appearance when a wearer wears the pair of glasses, because the pair of fixing members contact with the head outwardly and upwardly. Furthermore, the nose-gripless frame has a complicated structure which will cause a high cost to manufacture, and it is not easy to carry or handle the eyeglasses.

In view of the shortcomings of the nose-gripless frame in the Korean Utility Model application, the present inventors develop a nose-gripless frame of a pair of eyeglasses, which can reduce the manufacturing cost and can be easily carried or handled. Also, the frame of the present invention can provide a wearer of the eyeglasses with all the benefits of a nose-gripless frame.

Detailed Description of the Preferred Embodiment Fig. 1 is a perspective view of a pair of conventional eyeglasses having a pair of nose-grips 10 on the frame. When the pair of eyeglasses is worn, the nose-grips 10 on the frame contact on the ridge of the nose of a wearer.

Fig. 2 is a perspective view of a pair of conventional eyeglasses having no nose-grips on the frame, which is disclosed in Korean Utility Model Application No. 92-18852. While the frame does not have a pair of nose-grips, it has a pair of fixing members 11 on a position of each rim. The nose-gripless eyeglasses are supported by gripping the ear-grips 12 on the ears of a wearer and contacting the fixing members 11 on the head. The fixing members are elastic inwardly so that they may support the eyeglasses. However, the nose-gripless frame does not have good appearance

when a wearer wears the pair of glasses, because the pair of fixing 30 members are fixed on the head outwardly and upwardly or vertically. Furthermore, the nose-gripless frame has a complicated structure which will cause a high cost to manufacture, and it is not easy to carry or handle the eyeglasses.

Fig. 3 is a perspective view of a pair of eyeglasses according to the present invention, which does not have nose-grips on the frame and has a pair of contacting devices on each rim of the frame. The nose-grips are not formed on the frame 1. Accordingly, when a wearer wears the eyeglasses, the frame 1 does not contact with the ridge of the nose. The nose-gripless frame of the present invention has a pair of rims 2 like a conventional frame of eyeglasses. The rims 2 are connected with a joint bolt 4 so as to be rotatably folded. Also, at the end of each rim 2 are formed an ear grip 3 that is 10 coated with a synthetic resin material, which is obvious to an ordinary skilled person in the art.

In accordance with the present invention, the nose-gripless frame 1 of eyeglasses comprises a pair of rims 2 on which a contacting device 20 is mounted flexibly against the face of a wearer. Fig. 4 is an enlarged perspective view of the contacting device 20 of the pair of eyeglasses of Fig. 3, and Fig. 5 is an exploded perspective view of the contacting device 20 of Fig. 4. The contacting device 20 comprise a cylinder 21 rotatably connected with the frame 1 by a joint bolt 4, a spring 26 inserted and installed in the cylinder 21, a piston rod 27 for pressing the spring 26, which is connected with a contacting member 22 and a rod 24 by a joint bolt 23, and a rod 24 for moving slidingly and rotatably against the rim 2, which is connected with the rim 2 by a joint bolt 25 at one end and with the contacting member and the piston rod by a joint bolt 23 at the other end.

The cylinder 21 is rotatably connected with the frame 1 by a joint bolt 4. The cylinder 21 has an outer diameter of about 3 mm.

A spring 26 is inserted in the cylinder and is elastically operated by a piston rod 27. The piston rod 27 is supported by the spring at one end which is is inserted in the cylinder, and connected with a contacting member 22 and a rod 24 by a joint bolt 23 at the other end. The rod 24 is connected with the rim 2 by a joint bolt 25 at one end and with the contacting member 22 and the piston rod 27 by a joint bolt 23 at the other end. The piston rod 27 has a head 28 at the end which is inserted in the cylinder 21. The head 28 of the piston rod 27 holds the piston rod 27 in the cylinder 21. The rod 24 is rotatably fixed on a position of the rim 2. Therefore, when a wearer wears the pair of glasses, the contacting members 22 are horizontally moved against the side face of the wearer and are elastically contacted.

Fig. 6 is a plan view of the contacting device 20 of the pair of eyeglasses when the device is outwardly pressed, for instance, when a wearer wears the eyeglasses. Fig. 7 is a plan view of the contacting device 20 of the pair of eyeglasses when the device is relaxed by the spring. The distance that a contacting member 22 is reciprocated by the spring 26 is in a range of 0.5 to 1.0 cm approximately. Such distance is sufficient for anybody to wear the eyeglasses, supporting the eyeglasses without falling slightly down, but not causing a stress on the side face for the contacting member to be contacted.

The nose-gripless eyeglasses of the present invention are supported by gripping the ear-grips 12 on the ears of a wearer and contacting the contacting members 22 on the side face.

The contacting member 22 consists of a contacting part which is contacted with the side face of a wearer, and a connecting part which is connected with a piston rod 27 and a rod 24 by a joint bolt 23. The contacting part is made of a synthetic resin material, considering a good feeling of the contacting member 22 on the side face. A soft resin material is preferably employed. The contacting

part has a surface of a oval shape. The connecting part is made of steel such stainless steel or the same material as the frame. The materials of the contacting member and the processes for preparing thereof can be easily carried out by an ordinary skilled person in the art.

The present invention has effects avoiding all the shortcomings of a conventional frame of a pair of eyeglasses, being tightly worn without sliding downward during wearing, not giving a stress on the nose of a wearer, not printing traces on the nose of a wearer, being manufactured with an economic cost, and being easy to carry or handle.

Having described this invention, however, many modifications and changes thereto will become apparent to those skilled in the art to which it pertains without deviation from the spirit of the invention as defined by the scope of the appended claims.
