Is fixed in a state of being received in the recess.
In addition, the present invention is a connection mechanism between a front frame that holds a lens and an armor that is provided at each end of the front frame and in which a temple is bent via a hinge. The coupling mechanism has a band-shaped elastic material having a forward U-shape, and one end portion of the elastic material is fixed to the front frame, and the other end portion is formed on the armor. When a lateral force is applied and the U-shaped elastic material is displaced, a means for absorbing the impact force is adopted.

As shown in claim 1, in the spectacle frame according to the present invention that employs a coupling mechanism between the front frame and the armor, when a lateral force acts on the front frame and an impact force acts on the armor. In addition, this impact force is absorbed by the displacement of the forward U-shaped connecting member. Thereby, while being able to exhibit a favorable restoring force, it is possible to exert a buffering effect on the armor and the temple connected to the armor via a hinge, and further, the elastic material exhibits elasticity and the user's head Since the head is sandwiched, the head is not tightened, and the entire width can be made substantially the same as the width between the temples.
Further, when the connecting member is formed of a strip-shaped plate material as in claim 2, when the impact force is applied, the acting force per unit is reduced, and a good restoring force and a reliable buffering effect can be exhibited. it can.
Furthermore, if the hollow part which receives the edge part of a strip | belt-shaped connection member is formed in the side surface of an armor like Claim 3, there will be no fear that it will disassemble at the time of an assembly.
Furthermore, by configuring as shown in claim 4, when a lateral force acts on the front frame and a displacement force acts on the armor, this acting force is generated by the forward U-shaped connecting member. Absorbed by displacement. As a result, it is possible to exert a good restoring force, to exert a buffering action on the armor and the temple connected to the armor via a hinge, and the head is flexed so that the head is tightened. In addition, the overall width can be made substantially the same as the width between the temples.
Further, when the connecting member is formed of a strip-shaped plate material, the acting force per unit is reduced when an impact force is applied, and a good restoring force and a reliable buffering effect can be exhibited.
Furthermore, if the hollow part which receives the edge part of a strip | belt-shaped connection member is formed in the side surface of an armor, there will be no fear that it will disassemble at the time of an assembly.

Embodiments of the present invention shown in the drawings will be described below.
FIG. 1 is a schematic plan view of a spectacle frame 1 according to the present invention, FIG. 2 is a schematic front view, FIG. 3 is a schematic side view, and FIG. 4 is a schematic view of a coupling mechanism. ing.

  The spectacle frame 1 is a half rim type, and has a pair of left and right lenses 2 and 2 and is connected by a bridge 4 and has rims 3 and 3 forming a front frame. Armor is arranged outside the 3 at a predetermined interval.

  As shown in detail in FIG. 4, the armor 5, 5 is located outward with a predetermined distance from the rim 3, 3, and recessed portions 6, 6 are formed on the rim 3, 3 side, Temples 8 and 8 are arranged at 5 and 5 via hinges 7 and 7 so as to be foldable.

  The rims 3, 3 and the armor 5, 5 are connected by connecting members 9, 9 having a forward U shape, and this connecting member is formed of an elastic material and has one end. Is fixed to the rims 3 and 3, and the other end is fixed in a state of being located in the recesses 6 and 6 provided in the armor 5 and 5.

  The temples 8 and 8 that are foldably attached to the armors 5 and 5 via hinges 7 and 7 are provided with moderns 10 and 10 at their rear ends.

  In addition, 11 and 11 are nose pads which contact | abut on both sides of a user's nose, The leg parts 12 and 12 which support this nose pad 11 and 11 are being fixed to the inner side of the rim | limbs 3 and 3. .

In the spectacle frame 1 configured as described above, first, the temples 8 and 8 are expanded from the folded state to the state shown in the figure, and the user can use it.
Then, in order to start using the user, the head is inserted between the temples 8 and 8, that is, the upper side of both ears of the user's head is sandwiched between the temples 8 and 8.

  When the two temples 8 and 8 are expanded at the time of clamping, not only the temples 8 and 8 are expanded with the hinges 7 and 7 as fulcrums, but also the connecting members 9 and 9 made of an elastic material are somewhat expanded. , 8 is also slightly displaced outward, so that it is attached in close contact with the user's head.

That is, by connecting the temples 8 and 8 in the expanded state to be narrower than the head, the connecting member 9 provided in a forward U-shape between the rims 3 and 3 and the armor 5 and 5. 9 and the temples 8 and 8 themselves are displaced outwardly, the temples 8 and 8 themselves elastically contact the user's head.
Even when the temples 8 and 8 themselves are not displaced outwardly, the connecting members 9 and 9 made of an elastic material are elastically deformed so that the temples 9 and 9 come into contact with the head of the user in a planar shape. become.

  Therefore, unlike the case where the user feels a strong wearing feeling due to the large force acting on the part where the temples 8 and 8 come into contact with the head, the small force is applied to each part of the head, so that it is used for a long time. Even so, the user does not feel a strong fit. In addition, since the user's head is securely held, there is no possibility of shifting or dropping during use.

  Furthermore, since the U-shaped connecting members 9 and 9 are only arranged between the armors 5 and 5 and the rims 3 and 3, the lateral width of the spectacle frame does not increase. When an impact force is applied from the side, the U-shaped width of the connecting members 9 and 9 can be reduced and the impact force can be reduced.

Moreover, you may form the connection members 9 and 9 in a U shape with a rod-shaped elastic material. Further, when a belt-like plate material is used, the acting force per unit is reduced when an impact force is applied, and a good restoring force and a reliable buffering effect can be exhibited.
Furthermore, if the recesses 6 and 6 for receiving the end portions of the strip-shaped connecting members 9 and 9 are formed on the side surfaces of the armor 5 and 5, there is no fear of disassembly during assembly.

In the embodiment, the front frame may be a full rim type.
Further, the temple itself may or may not be elastically displaced, and in the case of a displacement, the elastic member and the temple cooperate to become more flexible. The material of the temple may be either metal or resin.
