[Industrial applications]

 The present invention relates to a lens support mechanism for band suspender type eyeglasses, and more specifically, a rim bar having a fitting hole and a through hole are formed when a band is hung on a groove formed in the lens to fix the lens to the rim bar. The lens support mechanism of the band suspender type eyeglasses that can securely hold the lens on the rim bar by fitting the fastener with the band inserted through the through hole into the fitting hole of the rim bar. Is.

[Prior art]

 Conventionally, in eyeglasses of a type in which a grooved lens is held by a band, it is known that a through hole for passing the band is directly formed in the rim bar, and the lens is fixed to the rim bar by passing the band through the through hole. It was However, this direct drilling method has a drawback in that the burr (especially a metal rim bar) generated when a hole is drilled in the rim bar is easily rubbed by the band. Moreover, when a hole is made in a metal rim bar or a hard plastic rim bar, the inner peripheral surface of the hole is hard and slips well, so that the band is easily removed from the hole. Therefore, a method has been adopted in which a sleeve-shaped cushioning material is inserted into each through hole to reduce friction and slippage of the band.

However, in such a cushion material insertion method, although it is possible to effectively prevent the band from breaking and the band coming off, since the cushion material is inserted into all the through holes, the number of parts is reduced. However, there is a drawback in that the time and effort required for assembly also increase.

[0004]

[Technical issues to be solved]

 The present invention has been made in view of the above drawbacks of the conventional band-type eyeglasses, and it is possible to effectively prevent the band from breaking or coming off while keeping the number of necessary components to a minimum. It is a technical object to provide a lens support mechanism for band suspender type glasses that can securely hold the lens on the rim bar by using such a mechanism.

[0005]

[Means adopted for solving the problem]

 Means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, the present invention is a rim bar 1 having a fitting hole 11 penetrating the inner and outer circumferences near the left and right lower chord ends; and a plug-like member fitted into the fitting hole 11 of the rim bar 1, A buckle 2 having at least two sewing holes 21 penetrating the inner and outer circumferences; a lens 3 having a band groove 31 engraved at least on the lower edge thereof; And a band suspender 4 for fixing the band suspender 4 to the band groove 31 of the lens 3 and both ends of the band suspender 4 in the sewing hole 21 of the buckle 2 in a bent state. The technical problem is solved by adopting a lens supporting means that holds the lens 3 by sewn in and out, and by fitting the buckle 2 into the fitting hole 11 of the rim bar 1. There is a feature.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. 1 is an exploded perspective view of a first embodiment product constructed by applying the present invention, FIG. 2 is a front view of a first embodiment product constructed by applying the present invention, and FIG. A partial enlarged side view showing a part of the side surface, FIG. 4 is a sectional view taken along line AA in FIG. 3, FIG. 5 is an exploded sectional view showing a part of the first embodiment product, and FIG. 6 is a second embodiment. It is an exploded sectional view showing a part of goods.

First, a first embodiment product constructed by applying the present invention will be described. As shown in FIG. 1, the first embodiment product has a rim bar 1 having a fitting hole 11 penetrating the inner and outer circumferences near the lower chord ends of the left and right, and a buckle fitted into the fitting hole 11 of the rim bar 1. 2, a lens 3 with a band groove 31 engraved, and a band suspender 4 for attaching and holding the lens 3 to the rim bar 1. When these are combined, a band type as shown in FIG. You can get glasses. A groove 12 is formed in the inner peripheral surface of the rim bar 1, and a convex member 13 is inserted into a part of the groove 12, and the band groove 31 of the lens 3 is inserted into the convex member 13. The upper edge of is fitted. The buckle 2 is a plug-like member fitted into the fitting hole 11, and at least two sewing holes 21 are formed to penetrate through the inner and outer circumferences. As shown in FIG. 3 and FIG. 4, both ends of the band suspender 4 are inserted into the sewing hole 21 from the inside to the outside, and the ends of the band suspender 4 which are pulled out to the outside are further inserted into the inside to make a flexion bending. Set to state. FIG. 5 shows an exploded sectional view before the buckle 2 is fitted into the fitting hole 11. Recesses 22 are formed between the sewing holes 21 so that the band suspenders 4 do not protrude much to the outer peripheral side. A flange 23 is provided on the outer peripheral edge of the buckle 2, and the flange 23 is hooked on the outer peripheral surface of the rim bar 1. A band groove 31 is engraved at least on the lower edge portion of the lens 3, and the band suspender 4 is fitted in the band groove 31 while the both ends of the band suspender 4 are sewn into the buckle 2. Set to 21 inside, outside and inside in the bent state. By fitting the buckle 2 into the fitting hole 11 of the rim bar 1, the lens 3 can be securely held on the rim bar 1. As the buckle 2, a synthetic resin molded body that can effectively prevent the band suspenders 4 from breaking or coming off can be used. Further, if a rubber-like synthetic resin molded body is used, the effect of preventing the band coming off is further enhanced. Increase.

Next, a second embodiment product constructed by applying the present invention will be described with reference to FIG. FIG. 6 is an exploded sectional view showing a part of the second embodiment product, which is different from the first embodiment product only in the shapes of the fitting hole 11 and the buckle 2 of the rim bar 1. The fitting hole 11 of the rim bar 1 in the second embodiment is formed in a mortar shape having a wide outer peripheral side and a narrow inner peripheral side, and the outer surface of the buckle 2 is also shaped like a mortar. is there. The sewing hole 21 of the buckle 2 is formed in a tapered shape as shown in FIG. When the band suspender 4 is passed through the taper sewing hole 21 in a stretched and bent state, the band suspender 4 is sewn in an Ω shape so as to become narrower toward the inner peripheral side. It becomes more difficult to come out. Therefore, it is particularly useful when the buckle 2 is not made of synthetic resin having a large frictional resistance. When a rubber-like synthetic resin having a large frictional resistance is used as the material of the buckle 2, the sewing hole 21 of the buckle 2 is formed into a reverse taper shape opposite to that shown in FIG. It is also possible to form so as to widen to the side.

The embodiment of the present invention is generally as described above, but the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. However, for example, the inside of the hole of the buckle is carved in a sawtooth shape to further enhance the effect of preventing the band from being pulled out, and the buckle is colored to obtain a colorful design eyeglass frame. It goes without saying that any of these modifications can be included in the technical scope of the present invention.

[0011]

[Effect of device]

 As described above with reference to the embodiments, according to the present invention, in the band-type glasses for fixing the lens to the rim bar by putting the band on the groove formed in the lens, the rim bar having the fitting hole and the through hole are formed. By using the formed buckle and fitting the buckle through which the band has been passed through the through hole into the fitting hole of the rim bar, the number of required parts can be kept to a minimum and the band breakage and band loss can be effectively achieved. This makes it possible to hold the lens on the rim bar quickly, reliably, and stably. Therefore, the industrial practical value is great.
