Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pliers used for correcting the opening degree and inclination of a temple of eyeglasses.
[0002]
[Prior art]
Most of the ready-made glasses need to be modified in shape such as temples and pads in accordance with individual users. For this purpose, dozens of dedicated pliers are commercially available. These pliers are provided with, for example, a groove or a recess in a beak portion (Japanese Patent Laid-Open No. 11-90841) in order to securely hold a specific portion of the glasses. Further, there is a plier in which one or both of the beaks is screwed with a plastic holding block to prevent the pinched portion and its peripheral portion from being wrinkled (Japanese Patent Laid-Open Nos. 11-90840 and 11-90842). Issue gazette).
[0003]
When adjusting the left / right direction of the temple when viewing the glasses from the plane, or when adjusting the vertical tilt of the temple when viewing the glasses from the side, change the corner angle of the temple to larger or smaller. Adjust the vertical angle of. When this adjustment is performed, depending on the shape and structure of the wisdom or the structure on the rim side, for example, the rim is held together with the rim lock by the pliers, or the base on the rim side is held. However, rims and rim locks cannot be clamped in the case of two-point frame type glasses with the lower rim of the rim omitted, or glasses without rims that are screwed directly to the lens. There is no other way but to fix the temple and adjust its bending and inclination.
[0004]
[Problems to be solved by the invention]
The temple posture correction as described above can be performed with existing pliers in many cases, but depending on the structure, it may not be possible to pinch wisdom. Satoshi is formed in an L shape with a base fixed to the rim lock or lens and an arm protruding from the base toward the back of the glasses. However, the projecting dimension of the arm is extremely small mainly due to design requirements. May use wisdom. In this way, when the arm is short, the existing pliers make it difficult to securely fix the arm due to the hinge being in the way, and it takes a lot of time to correct the posture of the temple. In particular, in the case of glasses without rims, excessive force applied to the base of the wisdom could damage the lens, requiring careful attention to correct the posture of the temple.
[0005]
The purpose of the present invention is to adjust the degree of opening and inclination of the temple by holding a hinge that foldably connects the wisdom and the temple, in particular, a two-point frame type eyeglass frame, An object of the present invention is to provide a plier suitable for correcting the posture of a temple, such as glasses without rims that are screwed.
[0006]
[Means for Solving the Problems]
The temple straightening pliers of the present invention include a first beak 4A and a second beak 4B to which a plastic clamping block 10 is attached as shown in FIG. In the first beak 4A, a pair of clamping arms 5 for clamping the connecting ends of the wisdom 21 and the temple 22 together with the hinge 23 is provided in a forked shape. On one side of the clamping block 10, a flat clamping surface 12 facing the clamping arm 5 is provided. Therefore, the clamping block 10 and the both clamping arms 5 can clamp and fix the connecting end of the wisdom 21 and the temple 22 and the hinge 23 from the inside and outside.
[0007]
The pair of hinges 23 includes a base portion 28 brazed to each of the connecting ends of the wisdom 21 and the temple 22, and a boss portion 29 provided continuously to the base portion 28. In the pair of sandwiching arms 5, fillet surfaces 6 are formed at curved contact corners with the hinges 23 along curved surfaces connecting the boss portions 29 and the base portions 28, respectively.
[0008]
The clamping block 10 is externally fitted with the mounting groove 11 provided on one side thereof to the mounting portion 7 provided on the second beak 4B, and is fastened and fixed with screws 13. The front-rear width of the holding arm 5 is set to be the same as or slightly smaller than the front-rear width of the mounting portion 7.
[0009]
Relief surfaces 16 are provided at the front and rear edges of the sandwiching block 10 on the sandwiching surface 12 side, and the sandwiching surface 12 is tapered toward the tip.
[0010]
[Effects of the invention]
When the pliers are used, as shown in FIG. 5, the hinge 23 provided at the connecting end of the wisdom 21 and the temple 22 is clamped and fixed by a pair of beaks 4A and 4B. Specifically, in the state where the sandwiching block 10 hits the outer surface of the connecting end between the wisdom 21 and the temple 22 and the pair of sandwiching arms 5 circumscribes the pair of hinges 23 fixed to the wisdom 21 and the temple 22, The connection end with 22 is fixed. In this state, the temple 22 is deformed in the vertical and horizontal directions as indicated by the intersecting arrows, or is tilted in the left and right directions as indicated by the curved arrows, whereby the degree of opening and inclination of the temple 22 can be adjusted. adjust. Thus, when the hinge 23 is clamped by the pliers, even if the arm portion 25 of the wisdom 21 is extremely short, the wisdom 21 and the temple 22 can be securely fixed via the hinge 23 without any trouble as shown in FIG. Even when the length of the arm portion 25 is short, such as a two-point frame-type spectacle frame or a rimless spectacle that the Ji 21 is screwed directly to the lens, the correction of the temple 22 is ensured. It can be done quickly and easily.
[0011]
According to the pliers in which the fillet surface 6 along the curved surface connecting the boss portion 29 and the base portion 28 is formed at the contact corner portion of the pair of sandwiching arms 5 with the hinge 23, the hinge 23 is sandwiched when the hinge 23 is sandwiched. Since the surface pressure acting on is dispersed, it is possible to well prevent the hinge 23 from being wrinkled when the temple 22 is corrected. Furthermore, since both sides of the boss portion 29 are sandwiched between the pair of sandwiching arms 5 via the fillet surface 6, both the hinges 23 can be sandwiched evenly and stably, and the left and right spacing of the base portion 28 is small. Also, the pair of hinges 23 can be securely clamped.
[0012]
If the front-rear width of the clamping arm 5 is the same as or smaller than the front-rear width of the mounting part 7 for the clamping block 10, the clamping force acting on the clamping block 10 can be received by the mounting part 7. Therefore, when the connecting portion between the wisdom 21 and the temple 22 is held, the holding block 10 can be prevented from being bent and deformed, and the wisdom 21 and the temple 22 can be securely held and fixed.
[0013]
According to the clamping block 10 in which the clearance surfaces 16 are provided at the front and rear edges on the clamping surface 12 side, and the clamping surface 12 is tapered toward the tip, for example, as shown in FIG. Even in the case where the decorative body 33 is provided near the connection portion, the posture of the temple 22 can be corrected by firmly fixing the wisdom 21 and the temple 22 together with the hinge 23 without being disturbed by the decorative body 33. .
[0014]
【Example】

In FIG. 2, the wisdom pliers are formed by assembling a pair of left and right sandwiching arms 1a and 1b in an X shape and fastening the crossing portion with a shaft 2, and a handle that curves outwardly on one side of the crossing portion. 3 and a pair of first and second beaks 4A and 4B are provided on the other side.
[0015]
The first beak 4 </ b> A is formed in a tapered shape from the base portion toward the projecting end in a side view, and is provided with a notch 9 extending from the front and rear central tip to the base end, and a pair of front and rear clamping arms 5 are provided. The clamping arm 5 clamps the wisdom 21 and the temple 22 together with the hinge 23 in cooperation with the clamping block 10 described later. Therefore, as shown in FIG. 1, the fillet surface 6 is formed in the contact corner part with the hinge 23 of both the clamping arms 5. The fillet surface 6 is rounded so as to follow a curved surface connecting the boss portion 29 and the base portion 28 of the hinge 23, thereby acting on the hinge 23 when the hinge 23 is sandwiched between the two beaks 4 </ b> A and 4 </ b> B. The surface pressure is dispersed to prevent the hinge 23 from being wrinkled. The opposing surface of the clamping arm 5 to the second beak 4B is formed as a flat surface, but when facing the clamping block 10 with a slight gap (over 3 mm) as shown in FIG. The planes are set to be parallel. This is to prevent both the beaks 4A and 4B from being in a substantially parallel posture when the connecting portion between the wisdom 21 and the temple 22 is clamped together with the hinge 23, thereby preventing the clamping portion from being pushed out toward the tip end side of the beak. It is.
