Description

  The present invention relates to an eyeglass frame in which temples are attached to embedded portions embedded on both sides of a resin-made front frame that holds the periphery of a lens via an elastic body.

  In general, there are a full rim type and a half rim type as shown in Patent Document 1 in the frame of eyeglasses. The temples that are in contact with the side portions of the user's head through the embedded portions are respectively attached to both sides of the back surface of the rim to which the left and right lenses are attached so as to be able to turn inward from a predetermined expanded state. It is possible.

  In the general spectacle frame configured as described above, the temple is turned from the both sides of the ear portion of the user's head in a state where it has been rotated outward and stopped at the maximum, that is, in a fully expanded state. It is used by the user, and the warp state of the temple is mainly adjusted according to the width of the user's head so that the user does not feel tight during use.

However, in the conventional spectacle frame as described above, an attempt is made to ensure the optimum state for the user mainly by adjusting the warp state of the temple, but the temple is integrated with the armor part. There is a problem that the adjustment of the temple affects the armor part attached to the rim.
Moreover, since the adjustment is mainly performed by adjusting the temple, the temple is bent without displacing the armor side of the temple, and a part of the inner surface of the temple is dotted on the user's head. As a result, the contact force on the head increases, and there is a problem that the head may be painful.

Because it is composed of a pair of elastic bodies and temples with modernity provided respectively through hinges on the side opposite to the embedded portion of this elastic body, not only the temples are displaced at the time of expansion, The entire temple can be displaced by the elastic body, and a part of the modern inner surface provided on the temple abuts against the user's head in combination with the resin front frame being slightly displaced. It came to come in contact with the surface instead of. As a result, the contact force with respect to the user's head can be reduced to reduce the feeling of wearing, and the possibility of causing pain to the user's head during use can be eliminated. In addition, since the nose pad assembly in which a part can be inserted into a recess provided in the center of the rear surface of the front frame and can be screwed, and nose pads are attached to both sides, the front frame is configured. The nose pad assembly can be easily mounted by simply inserting it into the recess of the front frame and stopping it.

Embodiments of the present invention shown in the drawings will be described below.
FIG. 1 shows a schematic plan view of a spectacle frame 1 according to the present invention, FIG. 2 shows a schematic front view, FIG. 3 shows a schematic view seen obliquely from above, and FIG. FIG. 4 (a) is a schematic diagram showing an expanded state, and FIG. 4 (b) is a schematic diagram showing a slightly folded state. 5 is a schematic detailed view showing a connected state of the front frame, the elastic body, and the temple, and FIG. 6 is a schematic view showing a connected state of the front frame and the nose pad assembly.

  The spectacle frame 1 is a resin-made full rim type, to which a pair of left and right lenses 2 and 2 are attached and a front frame 3 provided with a bridge portion 4 in the center, and both of the back surfaces of the front frame 3. The elastic bodies 5 and 5 provided at the outer end, and the elastic bodies 5 and 5 are provided on the opposite side of the front frame 3 via hinges 6 and above the ears of the user's head. The temples 7 and 7 are arranged, and the moderns 9 and 9 are provided at the ends of the temples 7 and 7 so as to come into contact with and hold the user's head. .

  The elastic bodies 5, 5 provided on both sides of the front frame 3 have embedded portions 8, 8 provided at one end thereof embedded in the outer end portion of the front frame 3, so that both outer ends of the front frame 3 are provided. It is fixed to the part. Further, both elastic bodies 5 and 5 are formed so as to have a large elasticity because their central portions are curved inwardly in an inverted U shape.

  Temples 7, 7 provided on the other ends of the elastic bodies 5, 5 through hinges 6, 6 are made of metal, and are attached in a state in which the modern 9, 9 is fitted to the ends. The ends of the elastic bodies 5 and 5 and the temples 7 and 7 are connected by hinges 6 and 6.

  Therefore, the hinges 6 and 6 can fold the temples 7 and 7 between a position where the temples 7 and 7 are fully opened and a position where the temples 7 and 7 are folded inward from this position.

  The nose pad assembly 12 has a bowl shape, pads 14 and 14 are attached to both sides via legs 13 and 13, and an insertion portion 15 is provided at the center. On the other hand, a recess 16 is formed in the center of the back surface of the bridge portion 4 in the front frame 3, and the insertion portion 15 of the nose pad assembly 12 can be inserted into the recess 16, while being inserted.
