Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plier for correcting the shape of a spectacle frame, and more particularly to a plier for adjusting the position of a pad in accordance with the difference in height and width of a user's nasal bridge.
[0002]
[Prior art]
The pad of the spectacle frame is supported so as to be tiltable in a plurality of directions by a pad box fixed to the lower end of a pad foot (Klings). Therefore, when adjusting the pad position, the pad box and the pad are sandwiched simultaneously by a dedicated plier, and the pad foot is bent in the front-back direction or the left-right direction. Since the concave surface for receiving the pad box is provided on the clamping surface of one beak of the pliers, it is possible to prevent the pliers from slipping or wobbling in a state where the pad box and the pad are sandwiched between the pair of beaks.
[0003]
[Problems to be solved by the invention]
The pad box includes a small pad box formed in a substantially cubic shape and a relatively large pad box formed of a rectangular frame. Conventionally, depending on the size of the pad box, dedicated pliers are prepared, and the pad position is adjusted by using them separately. Therefore, it was necessary to always have two types of pad pliers in the spectacles store. The appearance of the two types of pliers was almost the same, and only the concave structure provided in the beak was different.
[0004]
An object of the present invention is to provide a spectacle frame pad plier that can adjust the position of the pad in common even when the size of the pad box is different, thereby reducing the cost burden on the user.
[0005]
[Means for Solving the Problems]
The pad pliers of the present invention adjust the position of the pad P by simultaneously holding the pad P and the pad box B1 and B2 with the first and second pair of beaks 4A and 4B. A first recess 9 for receiving the small pad box B1 and a second recess 10 for receiving the large pad box B2 are provided near the tip of the clamping surface 7 of the second beak 4B. The 1st recessed part 9 is provided in groove shape in the state which cross | intersects the front end side of the clamping surface 7 to the width direction. The second recess 10 is formed to be recessed along the longitudinal direction of the sandwiching surface 7 and intersects the first recess 9 in a state where the opening edge near the tip coincides with the groove opening edge on the tip side of the first recess 9. is there. A clearance groove 13 for receiving the pad foot 16 is provided on the surface 12 between the first recess 9 and the protruding end surface of the second beak 4B so as to communicate with both the first and second recesses 9 and 10.
[0006]
A relief recess 11 that is deeper and narrower than the second recess 10 is formed in the center in the width direction of the second recess 10. A receiving surface 6 for receiving the pad P is provided on the holding surface 5 of the first beak 4A facing both the first and second recesses 9 and 10, and this receiving surface 6 is formed in a gently concave curved surface.
[0007]
[Action]
Since the first and second recesses 9 and 10 are provided on the sandwiching surface 7 of the second beak 4B, the large size can be obtained by using both recesses 9 and 10 according to the difference between the pad boxes B1 and B2. A single pad plier can be shared by both the spectacle frame provided with the pad box B2 and the spectacle frame provided with the small pad box B1.
[0008]
According to the pad pliers provided with the first and second recesses 9 and 10 intersecting each other, the pad P and the pad box B1 and B2 can always be sandwiched between the tips of the pair of beaks 4A and 4B. Easy to adjust and easy to use. Since the escape groove 13 communicating with both the concave portions 9 and 10 is provided at the tip of the sandwiching surface 7, the concave portions 9 and 10 are brought into close contact with the pad boxes B1 and B2, and the pad foot 16 can be bent more reliably. The clamping position can also be determined by the escape groove 13. The contact surface 17 on the side that contacts the nasal bridge of the pad P is usually formed in a gently protruding shape. In order to make the first beak 4A tightly contact the contact surface 17 and securely hold the pad P, a receiving surface 6 having a gently concave curved surface is provided on the holding surface 5 of the first beak 4A.
[0009]
【Example】
1 to 6 show an embodiment of a pad plier according to the present invention. In FIG. 2, the pad pliers are formed by assembling a pair of left and right sandwiching arms 1 </ b> A and 1 </ b> B in an X shape and fastening the intersecting portion with a shaft 2. Each of the sandwiching arms 1A and 1B is made of a forged product, and is finished by plating after grinding and shaping. One of the intersecting portions is provided with a pair of handles 3 and 3 which are curved in a protruding manner, and the other is provided with a first and second pair of beaks 4A and 4B.
[0010]
The first beak 4A is formed in a flat shaft shape, has a flat clamping surface 5 on the surface facing the second beak 4B, and the front and rear width (about 4.5 mm) of the flat shaft portion is constant. The thickness in the left-right direction is formed in a tapered shape so as to decrease as it approaches the tip. A receiving surface 6 for receiving the contact surface 17 (see FIGS. 5 and 6) of the pad P is formed in a gently concave surface near the tip of the clamping surface 5.
[0011]
The second beak 4B is formed in a flat shaft shape like the first beak 4A, but its total length is slightly shorter than that of the first beak 4A, and the thickness dimension in the left-right direction is formed thicker overall. Is different from the first beak 4A. The second beak 4B is provided with a flat clamping surface 7 on the surface facing the first beak 4A. As shown in FIGS. 3 and 4, a first recess 9 for receiving a small pad box B1 and a second recess 10 for receiving a large pad box B2 are provided near the tip of the clamping surface 7. Yes.
[0012]
3 and 4, the first recess 9 is provided in a groove shape so as to cross the clamping surface 7 in the front-rear width direction. The groove cross-sectional shape of the first recess 9 has a semi-oval shape when viewed from the front. This is because the outer corners of the small pad box B1 are rounded as shown in FIG. The second recess 10 is formed in a recess along the longitudinal direction of the sandwiching surface 7 in a state where it intersects the first recess 9. The second recess 10 is formed in an oval shape when viewed from the side facing the clamping surface 7, and one arc end thereof is made to coincide with the groove opening edge on the tip side of the first recess 9. Therefore, the opening edge of the second recess 10 appears only on the side continuous with the groove opening edge on the base end side of the first recess 9. A relief recess 11 that is deeper and narrower than the second recess 10 is provided in the center of the second recess 10 in the width direction.
[0013]
At the projecting end of the clamping surface 7, a narrow flat surface 12 of about 1 mm remains between the first recess 9 and the projecting end surface of the second beak 4B. The flat surface 12 comes into contact with the pad foot 16 when the pad boxes B1 and B2 are sandwiched between the recesses 9 and 10, respectively. Therefore, a relief groove 13 for receiving the pad foot 16 is provided in the center of the flat surface 12 in the width direction, and the relief groove 13 is communicated with both the first and second recesses 9 and 10. In the state where the pair of handles 3 are clamped, the beaks 4A and 4B are not parallel, so the flat surface 12 is in contact with the clamping surface 5 of the first beak 4A to define the clamping limit. Yes.
[0014]
FIG. 5 shows an example of the pad P supported by the small pad box B1, and FIG. 6 shows an example of the pad P supported by the large pad box B2. 5 and 6, reference numeral 15 denotes a rim of the spectacle frame, and 16 denotes a pad foot fixed to the rim 15. The pad P is made of a plastic molded product, and the contact surface 17 that comes into contact with the nose bridge is formed into a gently protruding surface.
[0015]
When correcting the position of the pad P, as shown in FIGS. 5 and 6, the first recess 9 ( Alternatively, the pad box B1 (or pad box B2) is clamped by the second recess 10). At this time, the pad foot 16 enters the escape groove 13. Accordingly, each of the pad boxes (B1 or B2) can be reliably captured by the first recess 9 or the second recess 10. Since the pad foot 16 is engaged with the relief groove 13, when the pad foot 16 is bent, the beaks 4A and 4B do not move in the width direction.
[0016]
In addition to the above embodiment, a protective layer is formed on the inner surfaces of the first recess 9 and the second recess 10 using plastic or rubber to prevent the pad box B1 and B2 from being pinched. Can do .
[0017]
【The invention's effect】
In the present invention, the first and second recesses 9 and 10 of the large and small sizes are provided in the second beak 4B, and even when the sizes of the pad boxes B1 and B2 are different by using them separately, only one plier is used. The position of the pad P can be adjusted. Therefore, it is only necessary to prepare a single pad plier at the spectacles store, and the cost burden for the adjustment tool can be reduced by that amount, and the pliers can be eliminated.
