Description

  TECHNICAL FIELD The present invention relates to a spectacle frame vine excellent in deformation and design.

  The glasses are composed of a front part and a temple attached to both sides of the front part, and the temple can be folded via a joint such as a hinge. There are various forms of the front part. In general, both rims are connected by a connecting member, and a Yoroi is brazed to the outside of the rim. There is also a type of front part in which the upper half half rim is used as the rim and the lower side of the lens is held by water thread. Further, edgeless glasses are often used which are configured by directly screwing both lenses to both sides of the connecting member without using a rim and by directly screwing a lens on the outside of the lens.

  Each of these front parts is attached with a nose pad that is supported by hitting the back of the nose, and the vines extending from both sides of the front part reach the ears from the side of the face and are inserted into the tips of the vines. It is designed to allow Modern to lock onto the ear. Thus, the glasses can be stably put on the face by the front portion and the vine.

  The metal vine is made of a thin wire and is made of a material with excellent spring properties so that it can be adapted to the side of the face. In addition, the resin vine has a metal core embedded inside to give strength, but its thickness is relatively large, and the contact area with the side of the face is that of the metal eyeglass frame. The stability when wearing spectacles is improved. Of course, the resin frame and the metal frame have different feels when applied.

  By the way, the vine is configured to bend and deform (bend) so that the glasses can be worn more stably and so as not to feel pain even when worn for a long time. Metal thin vines can easily bend and deform to fit the side of the face, and resin vines can also be bent to a large thickness, with moderate surface pressure acting on the side of the face and the back of the head. The glasses you wear are stable without being misaligned.

  Conventionally, joints called spring hinges are frequently used, and many of them are designed to bend the temples by improving the joint structure in addition to the spring characteristics (elasticity) of the crane itself. FIG. 10 shows a crane joint structure that functions in the same manner as a kind of spring hinge. (A) of the figure shows that the leaf spring (c) is attached to the armor (b) provided on both sides of the front part (a), and the tip of the leaf spring (c) is brought into contact with the crane (d). A spring force is applied to the crane (d). Therefore, the crane (d) can be swung and folded around the shaft pin (e) as a joint, and can be pushed outward.

  When pushing outward, the leaf spring (c) bends and the spring force that pushes back the crane (d) acts as a reaction force. Acts on the back of the head. In the case of (b) in the figure, a leaf spring (c) is fixed to the temple (d) side, and the tip of the leaf spring (c) is in contact with the armor (b). ) Is pushed outward, a spring force is exerted to deflect the leaf spring (c) and push the temple (d) back.

  FIG. 10 shows a crane joint structure that functions in the same manner as a spring hinge, but various other structures are known. By the way, when the leaf spring (c) is attached in this way, the appearance of the spectacle frame is greatly impaired. Glasses are required to be fashionable because they are worn on the face for the purpose of correcting myopia and presbyopia. Therefore, in the structure in which the leaf spring (c) is attached as shown in FIG.

  FIG. 11 is also a prior art of a crane joint structure that functions in the same manner as a spring hinge. In this crane joint structure, the armor (b) provided on both sides of the front part (b) is provided with springiness. If the crane (d) is pushed outward, the armor (b) is deformed. In the case of (a), the entire armor (b) is constituted by a leaf spring, and in the case of (b), a leaf spring is used as a part of the armor (b). Even if it is a crane joint structure shown to the same figure, it cannot be said that it is a preferable form on the external appearance of a spectacles frame.

  As described above, the conventional vine and vine joint structure has the above-described problems. The problem to be solved by the present invention is this problem, and provides a temple of a spectacle frame having a function of bending and deforming the vine itself and improving the appearance.

  The temple of the eyeglass frame according to the present invention has a structure in which a plurality of pieces are arranged and attached to a core material, and adjacent pieces mesh with each other. That is, it has a shape in which a concave portion is formed on one side and a convex portion is formed on the other side, and each adjacent piece has a convex portion fitted in the concave portion. However, the arranged pieces can be bent in accordance with the curvature of the core material.

  The pieces are arranged in mesh with each other using the core material as a guide. However, there are cases where the core material passes through a hole provided in the central axis of the piece, or a structure in which each piece is sandwiched between two upper and lower core materials. In this case, guide grooves into which the core material is fitted are formed at the upper and lower ends of each piece. And the number of pieces attached to the vine is not limited, and its size and shape are arbitrary. Of course, the tip of the vine has a modern locking mechanism for the ear.

  The crane according to the present invention has a structure in which a plurality of small pieces are arranged and attached to a core material, and has a connection form in which the concavo-convex portions formed on each piece mesh with each other. Therefore, the vine can bend flexibly and deform to fit the face side. That is, the small pieces arranged in the core material can be bent together with the curvature of the core material. Furthermore, by changing the size of the piece, the elasticity and deformation capacity of the vine can be freely adjusted.

  The vine constructed in this way is not as thin as a vine of a general metal eyeglass frame, but its bending deformation ability is excellent, and the eyeglass can be stably put on the face side face. That is, the elasticity of the vine is excellent while having a thickness corresponding to a resin vine. On the other hand, the arranged pieces form a three-dimensional design, forming a vine appearance that does not exist conventionally, and improving the design of the entire spectacle frame. In addition, by changing the color of each piece, a different vine appearance can be formed.

  1, 2, and 3 are embodiments showing a spectacle frame provided with a temple according to the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a side view. The basic form as a spectacle frame is the same as the conventional one, and has a front part 1 and two temples 2 and 2. The front part 1 is connected to rims 3 and 3 on which lenses are fitted by a connecting member 4, and both ends 5 and 5 are brazed. The nose pads 6 and 6 are attached to the inside of the rims 3 and 3 and below the connecting member 4.
