Description

[0001]
[Industrial applications]
The present invention relates to a structure for fastening eyeglass parts such as a front and a temple of an eyeglass frame, an eyeglass frame and a decorative part attached thereto, a nose pad and a pad foot, an eyeglass frame and a lens, and the like. The present invention relates to spectacles partially provided with a simple fastening structure.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a structure using screws or caulking has been used as a structure for fastening a component of an eyeglass frame or fastening a lens and an eyeglass frame in frameless eyeglasses (two-point frame). For example, a screw is used for a pivot shaft of a hinge that connects the front of the spectacle frame and the temple, and a screw is used for a fastening portion between the rim wire holding the lens and the wisdom. A caulking structure is used for attaching the nose pad to the pad foot and fixing the decorative component to the spectacle frame.
[0003]
However, the fastening structure using screws has the disadvantages that it takes time and effort to process the threads and cross holes for turning the screws and screws, and that the fastening part is easy to loosen. An accident occurs in which the lens comes off and the lens falls off the spectacle frame.
[0004]
In addition, fastening by swaging has the problem that fastening parts can not be removed at retail stores.For example, if there is a request to replace the decorative parts attached by the swaging structure, the glasses must be sent back to the frame maker. I couldn't change the decoration parts.
[0005]
Regarding the hinge pivot shaft connecting the front of the spectacle frame and the temple, a structure has been proposed in which a pivot shaft is formed by fitting a shaft member provided with a flange member at one end with a pipe member (actual open flat 4). -50819). In this fastening structure, the shaft member is provided with a deep slit to form a split pin, and a locking projection formed at the tip of the split pin is engaged with the end of the pipe member, thereby forming the split between the shaft member and the pipe member. This is a structure for locking the fitting.
[0006]
[Problems to be solved by the invention]
As described above, when a screw is used as the fastening structure, the cost of parts is increased, and a failure or accident due to loosening of the fastening portion is likely to occur. Further, in the fastening structure by swaging, it is difficult to exchange fastening parts. On the other hand, the fastening structure disclosed in Japanese Utility Model Laid-Open No. 50819/1992 has no risk of loosening, and the fastening operation is simple. However, once tightened, it is difficult to remove the shaft member. Since the strength of the shaft member must be ensured, the diameter of the shaft member becomes large, and the shape of the part of the fastening portion becomes large. For this reason, there is a difficulty in adopting a thin titanium frame whose lightness is a creed and a structure for fastening a frame and a frame of frameless eyeglasses to the frame.
[0007]
In view of the above prior art, the present invention has a simple fastening operation, does not loosen, can be removed once it is necessary if necessary, and has a large fastening part shape. It is an object of the present invention to provide an eyeglass part fastening structure that does not cause a problem and an eyeglass frame provided with such a fastening structure.
[0008]
[Means for Solving the Problems]
In the present invention, a shaft member 1 having a flange member at one end and a pipe member 2 are inserted and fitted in an axial direction as a tightening structure between the spectacle frame and the lens or the components constituting the spectacle frame, thereby fitting the shaft. A structure in which eyeglass parts are fastened between the flange members of the member 1 and the pipe member 2 is adopted. The shaft member 1 and the pipe member 2 are locked in the axial direction by fitting the projection 8 and the recess 5.
[0009]
As a locking means for locking the fitted state of the shaft member 1 and the pipe member 2, a ring-shaped or dot-shaped concave portion 5 is provided on the peripheral surface of the shaft member 1, and corresponds to the concave portion 5 of the shell of the pipe member 2. A concave portion 7 is provided at a portion where the shell protrudes inward, and the inner convex portion 8 of the shell formed by the concave portion 7 is engaged with the concave portion 5 of the shaft member, thereby forming the shaft member 1 and the pipe. The member 2 is locked in a fitted state.
[0010]
The engagement between the convex portion 8 and the concave portion 5 is performed by the elasticity of the concave portion 7 formed in the shell of the pipe member 2. That is, by forming the convex portion 8 by the concave portion 7, a space that allows elastic deformation is formed behind the convex portion 8. If necessary, the shaft member 1 may be a hollow shaft member, and the concave portion 5 may have a deformable structure.
[0011]
By forming the shaft member 1 and the pipe member 2 as a square shaft and a square pipe, it is possible to prevent rotation around the shaft when the shaft member 1 and the pipe member 2 are fastened. Such a structure is effective as a structure of a fastening portion between the lens and the frame of the frameless eyeglasses, a fastening portion between the nose pad 36 and the pad foot 34, and a fastening portion of a decorative component having directionality.
[0012]
Either the shaft member 1 or the pipe member 2 can be integrated with one of the parts fastened to each other. For example, the shaft member 1 or the pipe member 2 can be integrated with the frame 21 at the fastening portion between the lens and the spectacle frame. In this case, the frame itself is integrated with the shaft member or the pipe member. It becomes a collar member. When the structure of the present invention is used for a fastening structure of a decorative part or the like, it is reasonable to integrate the decorative part with the shaft member 1 or the pipe member 2.
[0013]
When the fastening structure of the present invention is used for the fastening portion between the lens and the frame, a buffer rubber layer or a buffer resin layer is provided on the outer surface of the pipe member or on the surface of the flange member that contacts the lens 22, so that the lens has a large local area. It is better not to cause stress. Further, when the thickness of the lens is various, by providing a plurality of concave portions 5 of the shaft member in the axial direction and providing spring washers between the flange member facing the frame and the frame, the lens of various thicknesses is provided. Can be tightened. That is, the concave portion closest to the lens thickness is engaged with the convex portion of the pipe member, and an error with the lens thickness occurring at that time is absorbed by the elasticity of the spring washer 29.
[0014]
[Action]
According to the fastening structure of the present invention, the component to be fastened is sandwiched between the flange member of the shaft member and the flange member of the pipe member, and the shaft member 1 is inserted into the pipe member 2 in the axial direction, thereby forming the concave portion. The eyeglass parts can be fastened with one touch by fastening the projection 5 and the projection 8. To remove the component once fastened, the concave portion 5 and the convex portion 8 are disengaged from each other by hitting the tip of the shaft member 1 (the opposite side of the flange) with the tip of a punch and tapping it lightly with a hammer. The member 1 can be withdrawn from the pipe member 2.
[0015]
Since the shaft member 1 in the structure of the present invention is not provided with a deep groove or the like, a reduction in strength can be avoided, and the diameter of the shaft member 1 can be reduced. It is possible to reduce the size of the parts in the attachment part.
[0016]
The concave portion 5 of the shaft member and the convex portion 8 of the pipe member can be easily formed at accurate positions by rolling if provided in a circumferential shape, or by punching if provided in a dotted shape. The shaft member 1 and the pipe member 2 are preferably made of metal from the viewpoint that they can be miniaturized. However, for example, when they are used as a fastening structure for a resin frame, they can be made of resin. The shaft member and the pipe member made of resin can be easily manufactured by injection molding, and can also be easily formed integrally with the frame made of resin.
