JP4664401B2 - Length-adjustable temple and glasses provided with the temple - Google Patents

Description

  The present invention relates to a temple whose length can be adjusted and a pair of glasses including the temple.

  In general, a spectacle frame has a large number of spectacle parts such as a front frame (rim) that holds the lens, a bridge that connects the left and right rims, an armor, a temple, and an ear hook at the rear end of the temple (this is called modern). It is made by connecting with.

  In recent years, there have been an increasing number of eyeglass frame designs with a wide temple width. Structurally, many metal temples have a structure in which a plastic resin is inserted into a metal core. Some ear hooks are made of metal. Some of the temples made of plastic resin include those with a metal core, and those made entirely of plastic resin. Furthermore, there are various rims for spectacles, such as plastic resin, metal, rimless type, and nyroll type.

  By the way, in order to be a comfortable eyeglass frame, it is necessary for the eyeglass wearer to adjust the length to the ear hooking part (modern bending part) so that the ear hooking part can be hung just on the ear of the eyeglass wearer. There is.

  If the length of the temple is adjusted within a few millimeters, even if it is adjusted by re-bending the modern bending position, it does not change much in appearance, so this method is used for most adjustments. If the core of the modern part is almost the same thickness as the metal temple, it can be adjusted by cutting off the tip of the core and reattaching the modern. .

  Further, in Patent Document 1, a groove is formed in a longitudinal slide hole and an inner portion thereof, and a long hole is formed in a metal temple in which a slider member is movably disposed in the groove. The position relative to the modern temple, that is, the temple length, can be adjusted by screwing it into the screw hole of the slider member with a fixing screw that penetrates the modern, crosses the modern, and penetrates the drilled hole. This mechanism is disclosed.

  However, in the conventional method of re-bending and adjusting the modern bending position, the re-bending operation is not easy, and the shape balance between the left and right is lost due to errors in the bending position and errors in the bending condition. Sometimes, in the worst case, the shape changed so that it could no longer fit into the originally prepared glasses case. In order to avoid this, it is sufficient to prepare several types of temples having different lengths. However, wasteful inventory is required, resulting in high costs. In particular, since a plastic resin temple has many color variations, such a method cannot be adopted.

  Then, although it is also considered to employ a mechanism as disclosed in Patent Document 1, this mechanism is fitted with a modern with a long hole drilled in a metal temple, and the position of this modern temple is It is adjusted by sliding by loosening the fixing screw, and is fixed to a predetermined length by tightening the fixing screw after the adjustment, and there is a problem that it cannot be adopted for a temple that places importance on design. That is, depending on the adjustment position for the modern temple, a part of the slide hole formed in the metal temple is exposed, and the head of the fixing screw is not always exposed, but protrudes from the modern, This is because the appearance is not preferable.

  In view of such problems, the object of the present invention is to provide a temple that can be adjusted in length without impairing design, and that is capable of maintaining a stable coupling state between connected spectacle parts. There is.
