[Industrial applications]

 The present invention relates to a jig used for punching a lens support for a lens of rimless spectacles, and more specifically, to two-point support rimless spectacles (hereinafter referred to as two-point spectacles) and one-point support rimless spectacles ( The following relates to a simple and inexpensive lens drilling tool jig (jig) that can accurately and quickly perform appropriate hole drilling on a lens of a one-point eyepiece. This is extremely useful for eyeglass stores who need to properly perform lens hole processing at an appropriate position according to a variety of different lenses depending on their eyesight or the like.

[0002]

[Prior art]

 Support holes that penetrate the front and back are drilled in the inner and outer parts of the left and right lenses, which form the front part of the spectacles, and the bolts placed through the strap on the bridge side and the strap on the bracket side are attached. Two-point eyeglasses that penetrate the support holes and lock with nuts are well known in the art, and because they have a wide field of view and are bright, and they are also light and smart, they have a wide demanding group centered on young people and have been well received. ing.

[0003] Further, the desire of spectacles consumers for wide field of view, clearness, and lightness and smartness of spectacles is the emergence of so-called one-point spectacles in which left and right spectacle lenses can be supported in a cantilever manner only inside the bridge side. Today, the number of enthusiasts is increasing.

By the way, what has been conventionally demanded for such two-point eyeglasses and one-point eyeglasses establishes a rational technique capable of appropriately and easily forming a support hole in a lens without fail. Was that.

Conventionally, when a support hole is drilled in a lens of two-point eyeglasses or one-point eyeglasses at an eyeglass store, a mark is made on a target portion of the left and right lenses cut into a predetermined shape with a marking pen or the like, Using that mark as a reference, drilling was performed using a drill. For this reason, if the position of the mark is out of alignment or the contact angle of the drill point is out of alignment, the lens with the hole will no longer be discarded as a waste. It was not profitable, and it caused a great loss for the eyeglass store.

In addition, the eyeglass lens to be perforated has a peripheral lens thickness that increases as it becomes a near-sighted person or an astigmatic person with high intensity, which makes it difficult to apply the drill (angle of the drill with respect to the lens, etc.). Even with a slight deviation, it became a big deviation on the front side and the back side of the support hole.

In this embodiment, a perforation guide sleeve 5 is used in addition to the parts 1, 2, 3, 4, and P described above. The guide sleeve 5 has a nail shape as a whole, and has a drill guide hole 52 penetrating the shaft center at the center of a large-diameter head portion 51. A drill D for drilling a support hole H in the lens L to be processed is inserted into the drill guide hole 52, and the drilling operation is performed therein.

The jig of this embodiment is configured as described above, and when a lens is drilled using this jig, it is carried out as follows. The lens L to be processed is set in the holding space 31 of the lens set plate 3. In this case, it is assumed that the convex surface of the lens L is arranged upward, and that the right lens has the identification mark 14 of "N" on the right side in the drawing. When processing the left lens, reverse it. The lens horizontal line displayed on the lens L to be processed is matched with the horizontal reference line 32 of the lens set plate 3. In this case, it is preferable to attach protective tape to the front and back surfaces of the lens L to prevent scratches. Next, from the top, the drill set plate 1, the spacer 4, the lens set plate 3 (the lens L to be processed is set in the holding space 31 as described above), and the drill pad plate 2 are sequentially stacked and penetrated. Insert the fixing pin P into the holes 15, 45, 35 and 25, and place them stably. Then, the hole guide sleeve 5 is inserted into the drill hole 11 of the drill gauge plate 1, and then the point dp of the drill D is inserted into the drill guide hole 52 of the guide sleeve to rotate and drive. Then, in the lens L to be processed, a support hole H having a necessary hole diameter is opened at a correct position in which the lens is aimed. In this case, if the head portion 51 of the perforation guide sleeve 5 is fixed to the drill gauge plate 1 with an adhesive tape (not shown), the guide sleeve 5 does not move. You can do it. In this way, as shown in the example of FIG. 7, the lens L that has been subjected to the drilling process is attached with a bracket end piece that hinge-connects the bridge member and the temple by using the opened support holes H.H. It will be.

Although the embodiments illustrated in the present specification are generally configured as described above, the present invention is in no way limited to the above-mentioned embodiments, and is included in the description of “claim for utility model registration”. In this case, various designs or additional changes can be made. For example, although the spacer 4 is used in the above-mentioned embodiment, this spacer is omitted and a space is provided between the lens to be processed and the drill gauge plate 1. If necessary, it is possible to form a cavity on the lower surface of the drill gauge plate 1 to form a space for forming a void. Also, the lens set plate 3 may be formed thicker to hold the lens holding space 31. It is also possible to construct the processing target lens by a sink-fitting method, and all such design changes belong to the technical scope of the present invention.

Further, in the present invention, the perforation guide sleeve 5 is not necessarily required, and the drill D can be directly inserted into the drill hole 11 of the drill gauge plate 1 to perform perforation processing on the lens L to be processed. It goes without saying that this case also belongs to the technical scope of the present invention.
