Description

  The present invention relates to a framed optometric lens used for adjusting eyesight correction glasses, and more particularly to a framed optometric lens that is easy to assemble and can be produced at low cost.

  The optometric lens with a frame is indispensable when adjusting glasses for correcting vision such as for hyperopia and nearsightedness. Conventionally, as shown in FIG. A right-angle metal screw receiving piece 22 is brazed so as to face both ends of the fitted rim wire 21, and the lower end of the knob plate 24 is inserted into a slit 23 provided on one upper portion of the screw receiving piece 22. It was mainly used that was fixed by brazing with a pinch.

  However, the conventional framed optometric lens requires at least two brazing operations, and thus is troublesome to manufacture, requires skill, and has a high manufacturing cost. In order to adjust eyesight correction glasses, a large number of framed optometry lenses must be prepared, and the high manufacturing cost of framed optometry lenses is also in the price of eyesight correction glasses purchased by general consumers. Naturally, it rebounded and contributed to an increase in the retail unit price.

  Therefore, the inventor of the present application has proposed, as Utility Model Registration No. 3022515, an optometry lens frame that can be easily assembled and supplied at low cost. This lens frame for optometry does not require brazing work and does not require special skill even when assembled, so it has excellent features that can be manufactured at a lower cost than the conventional one, but the positional relationship between the lens body and the frame body There is a problem that it cannot be used for a gradual reduction lens or the like that requires strictness. In other words, in the case of a gradual reduction lens in which a hyperopic area and a nearsighted area coexist in one lens, the circumferential position in the lens frame must be set correctly, and the lens will idle in the frame. This is because if the lens is deviated from the proper position and rotated in the circumferential direction carelessly, a correct correction value cannot be obtained and an optimal correction lens cannot be obtained.

As a result of research to solve the above-described problems related to the optometry lens with a frame used when adjusting eyesight correction glasses, the present inventor is said to be low-cost with the utility model registration No. 3022515 previously proposed. Taking advantage of these advantages, we succeeded in developing an optometric lens with a frame that can be applied to special lenses that require strictness in the positional relationship between the lens body and the frame body, such as a gradual reduction lens. This is what we propose here.

A lens having a circular outline and integrally formed with a small protrusion facing outward in the diameter direction at one place on the periphery;
Both ends of the ring-shaped rim line covering the outer peripheral edge of the lens are bent and raised at a substantially right angle in a facing state to form a pair of rising pieces, and through holes are provided in the middle of these rising pieces.

  Unlike a conventional framed optometric lens, no brazing operation is required, so that it is very easy to manufacture and a framed optometric lens can be manufactured at low cost. In addition, since the small protrusions formed on the periphery of the lens prevent the lens from rotating within the frame, there is no need for a test lens for bifocal glasses that requires accurate holding of the relative position of the lens within the frame. It can be used without problems and has a wide range of applications.

  The biggest feature exists in that small protrusions are provided on the outer frame of the lens, and rising pieces are provided at both ends of the rim wire constituting the frame, and the rising pieces are inserted and fixed to the engaging blocks of the knob plate. .

  FIG. 2 is an enlarged front view of the framed optometry lens according to the present invention, with a part cut away from Example 1, and FIG. 3 is an enlarged perspective view of the main part for explaining the assembly state.

  In the figure, reference numeral 1 denotes a lens having a circular planar shape, and a small protrusion 2 facing outward in the diameter direction is integrally formed at one portion of the periphery thereof.

  Reference numeral 3 denotes a ring-shaped rim wire that covers the outer peripheral edge of the lens 1 and constitutes the frame body 11. Both end portions of the rim wire 3 are bent up at a substantially right angle in a facing state to become rising pieces 4. In the middle of the rising piece 4, a through hole 5 facing in the lateral direction is formed.

  On the other hand, reference numeral 6 denotes a knob plate made of metal or synthetic resin. The surface of the knob plate 6 can display the type of lens, optical characteristics, refractive index, and the like. A coupling block 7 having a thickness slightly larger than that of the piece 4 is integrally provided.

  The coupling block 7 is formed with a vertical hole 8 into which the rising piece 4 of the rim wire 3 can be inserted upward from the lower surface thereof. The hole 9 is opened, and the rising edge 4 of the rim wire 3 fitted into the periphery of the lens 1 is inserted by inserting a pin 10 into the through hole 9 with the rising piece 4 of the rim wire 3 inserted into the vertical hole 8. The piece 4 is fixed to the connecting block 7 of the knob plate 6. Note that a screw rod may be used in place of the pin 10 and the rising portion 4 may be fixed by screwing the screw rod into the inner wall surface of the through lateral hole 9.

  The first embodiment has the above-described configuration, and the small protrusion 2 provided on the periphery of the lens 1 is sandwiched between the pair of opposed rising portions 4 and 4 of the rim wire 3. The rim wire 3 is fitted to the periphery of the lens 1, and in this state, the rising pieces 4 and 4 are inserted into the vertical holes 8 of the connecting block 7, and a pin 10 or a screw rod is inserted into the through horizontal hole 9. The plates 6 are connected.

  Therefore, the troublesome work such as brazing is not required, and the lens 1 and the knob plate 6 can be coupled, and the efficiency of the assembling work is remarkably improved. Further, since the small protrusion 2 formed on the peripheral edge of the lens 1 is sandwiched between the pair of rising pieces 4 and 4 of the rim wire 3, the lens 1 in the rim wire 3 is rotated or bent carelessly. Therefore, the relative position is accurately maintained, so that the present invention can be applied without any problem to a test lens for bifocal glasses and has a wide application range.

  Next, Example 2 of the optometric lens with frame according to the present invention will be described with reference to FIG. In the second embodiment, the number of parts is further reduced and the assembly is simplified as compared with the first embodiment. Both ends of the rim wire 3 covering the outer peripheral edge of the lens 1 are similar to the first embodiment. In an opposed state, the rising piece 4 ′ is bent and rises substantially at a right angle, and the upper end of the rising piece 4 ′ is bent at a right angle toward the outer side, and a hook-shaped locking portion 12 is formed. ing.

  On the other hand, from the lower surface of the engagement block 7 ′ provided at the lower end of the knob plate 6, a vertical hole 8 ′ into which the rising piece 4 ′ and the locking portion 12 can be inserted is formed. A lateral hole 13 into which the locking portion 12 can be inserted is provided on the inner wall surface of the longitudinal hole 8 ′.

  The other parts are the same as those of the first embodiment, and the same reference numerals are given and the description thereof is omitted.
