Description

Glasses frame {GLASSES FRAME}

The present invention relates to a spectacle frame, and more particularly, to a spectacle frame in which a single thin metal plate is cut to configure the spectacle frame, so that the constituent parts are integrally formed.

In general, a spectacle frame is composed of a lens glove for fixing a lens, a leg part worn on the face, and a connection part for connecting the left and right lens glove to each other. In a spectacle frame made of a thin metal plate, the lens glove is also made of a thin metal plate.

A lens glove made of a thin metal plate is coupled to a coupling groove formed on a side surface of a lens to fix the lens. When a user puts on and takes off such glasses, the legs of the spectacle frame are spread, and the force of the legs is transmitted forward and backward to the coupling groove of the lens through the lens glove of the thin metal plate.

In this way, the force acting forward and backward on the coupling groove on the side of the lens through the lens glove damages and destroys the coupling groove on the side of the lens, which has relatively low strength.

An object of the present invention is to prevent the force due to the spread of the leg portion from being applied to the lens glove in a state in which the lens glove is coupled to the coupling groove on the side of the lens when wearing and taking off glasses made of spectacle frame parts made of one thin metal plate An object of the present invention is to provide a spectacle frame preventing damage to a coupling groove on a side surface of a lens.

In the spectacle frame according to an embodiment of the present invention, a leg portion, a lens glove, and a connecting portion are integrally formed by cutting a thin metal plate, and the leg portion and the lens glove are connected to each other at a middle portion through the connecting portion. One of the leg portion and the lens glove is manufactured by bending a spectacle frame component that is formed upside down with respect to the completed spectacle frame in the vertical direction.

1 is a front view of an integrated spectacle frame component obtained by cutting a plate material to manufacture a spectacle frame according to a first embodiment of the present invention. As an example, the spectacle frame component 100 may be manufactured by wire cutting or laser cutting a thin metal plate. As an example, the metal sheet may be made of recycled titanium.

Referring to FIG. 1 , the spectacle frame of the first embodiment is manufactured using a spectacle frame component 100 in which a leg portion 10, a lens glove 20, and a connection portion 30 are integrally formed by cutting a thin metal plate.

When wearing glasses, the leg portion 10 is located on the user's ear. The lens glove 20 fixes the coupled lens 50 together with the lens string 24 (see FIGS. 4 and 5). The leg part 10 and the lens glove 20 are connected to each other through the connection part 30 in the middle part. In this state, the leg portion 10 is formed upside down when compared to the completed spectacle frame state based on the vertical direction. That is, in the state of FIG. 1, the front surface (outer surface) 101 of the leg portion 10 is facing forward. The front surface (outer surface) 101 of the leg portion 10 is changed to the rear surface (inner surface) in the bent glasses frame.

The spectacle frame component 100 includes a first bending line 31 formed at the boundary between the connection part 30 and the leg part 10, and a second bending line 32 formed at the boundary between the connection part 30 and the lens glove 20. to provide The first and second bending lines 31 and 32 form a set interval D.
