Description

The connection structure of the frames and the glasses legs

The present invention relates to an eyeglass frame and a pair of spectacles for easily folding or unfolding the eyeglass frame and a pair of eyeglasses frames so that the eyeglass frame and the eyeglass frame can be flexibly and rapidly unfolded or folded or unfolded, Leg connection structure.

Generally, the eyeglass frame is composed of an eyeglass frame to which a lens is coupled and an eyeglass frame foldably coupled to an end piece of the eyeglass frame. The eyeglass frame and the eyeglass frame are made of a synthetic resin material or a metal material.

The glasses legs are configured to be folded or unfolded through a hinge provided on the spectacle frame. When the spectacles are worn, the spectacle legs are stretched. When the glasses are stored, the spectacle legs are folded to reduce the volume.

The hinge includes a hinge member, which is welded to the eyepiece and the end piece of the spectacle frame, respectively, and a hinge screw that not only joins the hinge member but also allows the eyeglass leg to be folded.

However, when the hinge is used for a long period of time, the hinge screw is loosened when the glasses are used for a long time. Therefore, it is inconvenient to use the glasses because the legs are loosened. Also, in order to replace the glasses legs, There was this uncomfortable problem.

Further, since the hinge member is joined to the end piece of the spectacle frame and the spectacle frame by welding, there is a problem in that the structure is complicated, the fabrication of glasses is troublesome, and the defect is often caused by the breakage of the welded portion.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide an eyeglasses eyeglass dispenser which is capable of providing a flexible intermittent feeling when folded or unfolded, Which is folded or unfolded, and also has a simple structure of an eyeglass frame and a pair of eyeglasses legs, thereby facilitating the detachment and attachment of the eyeglass legs.

To achieve the above object, the present invention provides an endoscope comprising: an end piece bent backward at an end of an eyeglass frame and having a driving cam at an end thereof; A spectacle leg having a receiving groove formed at its tip end so that the driving cam and the rear end of the endpiece are rotatably received and detachable; The front end of the plate spring is slidably contacted with the driving cam so as to cover the receiving groove of the tip of the eyeglass leg and to fix the rear end thereof.

In the present invention, when the eyeglass leg is folded or unfolded in a state where the driving cam of the end piece is fitted in the incision groove of the leaf spring formed at the tip end portion of the eyeglass leg, the leaf spring urges the elastic force of the leaf spring, And the eyeglass frame and the eyeglass legs are simple in structure, so that the eyeglass frame can be easily assembled.

1 and 2, an end piece (not shown) having a pair of driving cams 21 bent and extended outward at the end of the frame 10 and symmetrical to the upper and lower surfaces of the frame, 20); An eyeglass leg (30) having a receiving cam (21) and a receiving groove (a) in which a rear end portion of the end piece is rotatably received and is detachable so that an inner surface and a part of the front surface are opened; B which is formed such that a rear end of the end piece 20 is movably inserted in the middle of the receiving end of the end of the opened eyewear leg 30, (40) as a basic feature of the technical structure.

The rear end of the end piece 20 and the driving cam 21 are inserted into the front end receiving groove a of the eyeglass leg 30 so that the tip of the eyeglass leg 30 is engaged with the driving cam 21, The rear end of the end piece 20 can be moved in the front opening groove of the accommodating groove a of the eyeglass leg 30 as shown in Figure 3 when the eyeglass leg 30 is completely opened The leading end of the leaf spring 40 is brought into contact with the bottom dead point of the driving cam 21 and the folding of the eyeglass leg 30 to the inside is started. The distal end portion of the leaf spring 40 is brought into sliding contact with the curved surface facing the point.

At this time, the tip end of the leaf spring 40 is stretched and the resilient force of the repulsive force is increased. This force is transmitted to the eyeglass legs 30 as a reaction force, and the contact point of the leaf spring 40, The rotational force is transmitted to the eyeglass leg 30 in the opposite direction due to the increased elastic force.

5, the opened leaf spring 40 is restored to the original state, and the leaf spring 40 is driven to the front end of the leaf spring 40. As a result, The bottom dead point opposite to the cam 21 is brought into contact.

A fixing screw 41 is detachably attached to the rear end of the receiving groove a of the eyeglass leg 30 so that the rear end of the plate spring 40 is fixed by the fixing screw 41.

FIGS. 6 and 7 illustrate another embodiment of the present invention. In FIG. 6 and FIG. 7, a pair of driving cams 21 'bent and extended outward at the end of the frame 10 and symmetrical to the top and bottom surfaces of the frame are provided, An end piece 20 'which is formed so as to communicate with an opening groove d in which a rotational hole c passing through the center of rotation of both drive cams 21' opens inward; A leaf spring 40 'which is partly divided in the middle of the plate member end of the thin plate is provided so that the tip end of the leaf spring 40' can be elastically deformed about the rear end and the end piece (30 ') having a seating hole (e) through which a part of the outer surface of the distal end of the distal end portion of the eyeglass frame (20') is inserted, and a rotary support plate (31) And a rotation pin 32 rotatably fitted in the rotation hole c at the tip of the end piece 20 'and supported at both ends of the rotation support plate 31 of the eyeglass leg 30'.

In another embodiment of the present invention configured as described above, the distal end of the eyeglass leg 30 'is rotatably movable about the distal rotation hole' c 'of the end piece 20' by the rotation pin 32, When the leg 30 'is completely opened, as shown in FIG. 8, a part of the rear end outer side of the end piece 20' is movably fitted in the seating hole e of the leaf spring 40 ' The top end of the leaf spring 40 'is brought into contact with the bottom dead center of the eyeball 21' and the eyeglass leg 30 'is folded inward as shown in Fig. 9, the top dead center of the driving cam 21' The tip end of the leaf spring 40 'is brought into sliding contact with the curved surface facing the curved surface.

At this time, the tip end of the leaf spring 40 'is widened outward and the resilient force of repulsion increases, and this force is transmitted to the eyeglass leg 30' as a reaction force, and the contact point of the leaf spring 40 ' 21 ', the rotational force is transmitted to the eyeglass leg 30' in a direction opposite to that of the eyeglass leg 30 '.

10, the leaf spring 40 'is restored to its original state and the tip end of the leaf spring 40' is brought into contact with the distal end of the leaf spring 40 ' The bottom dead point of the opposite side of the drive cam 21 comes into contact.

11 shows another embodiment of the present invention. A rotation support plate 31 'for supporting both ends of a rotation pin 32' having a step on an outer circumferential surface thereof is welded to the inner side of the tip end of the eyeglass leg 30 ' Respectively.
