Description

  The present invention is an improvement of the spectacle frame, and more specifically, the temple position can be adjusted by a simple adjustment operation to securely fit the temple to the temporal region along the wearer's auricle. The present invention relates to a position adjustment mechanism for a spectacle temple that is difficult to shift the fixed position even when an external force is applied to the temple from the direction of the lens and that can stably hold the front frame at an ideal angle on the face.

  As is well known, when wearing spectacles, a structure in which a lens is disposed at a predetermined angle in front of the wearer's eyes by placing temples disposed on both sides of a front portion holding the lens on a rim or the like on the ear. It has been adopted.

  By the way, the shape of the ear varies widely depending on the individual, and it is not necessarily left-right symmetrical. Therefore, in the ready-made spectacle frame produced as an industrial product uniformly, the temple and the modern provided at the tip thereof are used by the wearer. There was a risk that the ear could not be properly fitted, and it was painful, or one of the temples was not properly placed along the base of the auricle, causing looseness.

  Conventionally, in order to fit the temple to the wearer's ear, the temple or the modern was bent and adjusted by hand. However, there was a possibility that the temple would be broken and damaged while the adjustment was repeated many times.

  Therefore, as a temple fitting structure, there is a type that changes the relative position between the temple and the front portion, and a structure in which a mechanism capable of adjusting the elevation angle is provided at the base end portion of the temple is disclosed (for example, Patent Document 1 and Patent Document 2).

However, as shown in FIG. 9, the angle adjusting mechanism is pivotally supported by inserting a fastening screw in a direction perpendicular to the main axis direction of the hinge screw that pivots the temple. When an external force is applied to the temple from a direction perpendicular to the direction, a large moment is applied to the shaft support portion at the base end, so that the fixed position is shifted by simply rotating the fixing screw as the rotation axis. There was a problem that.
Japanese Utility Model Publication No. 62-127521 (page 1-2, FIG. 1-5) JP 58-27122 A (page 2-4, FIG. 1-5)

The curved surface 12 of the curved tongue piece 1 is provided with a long-hole-shaped clearance through-hole 11 that penetrates the curved surface 12 vertically and is long at least in the longitudinal direction of the temple T. In the other part E ₂ , a slot groove 2 that matches the shape of the curved tongue piece 1 is formed between the half cylinder bracket 21,
The curved surfaces of the inner circumferential surface of the slot groove 2 and the curved surface 12 of the curved tongue piece 1 are slidably fitted to each other and slidably fitted.
A fastening hole 3 that can communicate with the clearance through-hole 11 in the insertion-side part E ₁ is provided through the half-cylinder bracket 21, and the clearance between the fastening hole 3 and the curved tongue piece 1 is provided. By fastening and fastening the fastening member 4 through the through hole 11, both members of the end piece parts E ₁ and E ₂ are connected and fixed, and the elevation angle of each temple T is set to pass through the clearance. Within the tolerance range of the fastening clearance between the hole 11 and the fastening hole 3, each can be adjusted independently,
The plate member 7 provided with the hinge hole 6 and the clearance long hole 71 is engaged with the base end portion of the temple T to constitute a piece part,
By fitting the plate member 7 into the slit 13 formed in the curved tongue piece 1 and adjusting the position of the clearance long hole 71, the fixing member 4 is inserted and fixed coaxially with the clearance through hole 11. It is also possible to adopt a technical means for adjusting the expansion range of the temple T by changing the position of the hinge hole 6.

Further, in order to solve the above problems, in addition to the above means, if necessary employing the technical means of providing an end-piece part E ₁ having a curved tongue 1 in the front coupling side.

In the present invention, the end piece is composed of two parts that are divided up and down and slidably fitted from the side, and a curved tongue is formed on the opposing end surface of one of the plug-in parts. On the curved surface of the curved tongue piece, there is provided a clearance through-hole that penetrates the curved surface up and down and is long at least in the longitudinal direction of the temple, while the other part has the curved tongue A slot groove matching the shape of the piece 1 is formed between the half-cylinder bracket,
While slidably fitting the curved surfaces of the inner circumferential surface of the slot groove and the curved surface of the curved tongue piece,
A fastening hole that can communicate with the clearance through hole in the plug-in part is provided through the half-cylinder bracket, and the fastening hole and the curved tongue piece are passed through the clearance through hole. By fastening and fastening the fastening member, both the members of each end piece part are connected and fixed, and the elevation angle of each temple is within the fastening clearance allowable range of the clearance through hole and the fastening hole, Each can be configured to be independently adjustable.

  Therefore, by using the position adjustment mechanism of the present invention, the temple position can be adjusted with a simple adjustment operation to securely fit the temple to the temporal region along the wearer's auricle, Even if an external force is applied to the temple from any direction, it is difficult to shift the fixing position, and the front frame can be stably held at an ideal angle on the face.

  Even when the temple receives an external force, there is no rotating shaft on the base end side, so rotation around the axis can be prevented and frictional resistance can be increased to prevent displacement of the fastening portion. Therefore, the practical use value in the spectacle frame is very high.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described in more detail with reference to the drawings specifically shown as follows.

“First Embodiment”
A first embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a curved tongue piece, and this curved tongue piece 1 protrudes from the opposed end face of _one of the plug-in parts E ₁ divided by the end piece E.
