Abstract

(57) Abstract [PROBLEMS] To provide lens loss prevention spectacles that are extremely simple in structure and have no fear of lens loss even when an external force is applied. An outer end portion (11) of a rim (1) that holds a lens (L).
A deformation allowance space S is created between the base ends of the pair of upper and lower splitting parts 2A and 2B provided on 11 and the outer surface of the lens L. This deformation allowance space S causes the splitting parts 2A and 2B to receive an external force. It can be elastically deformed accordingly. [Effect] Since the deformation allowance space is created between the split portion and the lens outer surface, even if external force concentrates on the split portion, these split portions divide the concentrated external force in two and support the external force at the same time. Accordingly, the split portion elastically deforms and absorbs the external force.

[Technical field to which the device belongs]

 The present invention relates to lens loss prevention spectacles, and more particularly, to lens loss prevention spectacles that are extremely simple in structure and have no fear of lens loss due to external force.

[0002]

[Prior art]

 Recently, eyeglass frames that have a wide field of view and are lightweight and have a sleek design have been well received.In the eyeglass industry, a rim that holds an eyeglass lens and an ear hook temple that is arranged at the end of the rim are hinged. The narrowing of end pieces etc. is being actively promoted.

However, on the one hand, it has been pointed out that while the designability is improved by making each spectacle part narrower, the thin rimmed glasses immediately lose the lens due to a slight impact. That is, when an external force is applied to the narrow-edge spectacles, the external force concentrates on the end pieces of the left and right ends of the spectacle front frame, and the concentration of the external force causes the spectacle lens to be particularly close to this tip. It was not uncommon for them to be lost.

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is an overall front view showing the configuration of lens loss prevention eyeglasses, which is an embodiment of the present invention, and FIG. 2 is a partially enlarged perspective view showing a state in which a split portion of the lens loss prevention eyeglasses is disassembled.

The lens loss prevention spectacles of the present invention are characterized by the configuration of the wisdom arranged at the left and right ends of the spectacle front frame. In FIG. 1, reference numeral 1 indicates a rim formed by bending a metal wire rod for holding the spectacle lens L in accordance with the lens shape. Both ends of the bent metal wire rod are rims. It is located on the side of the temple where 1 is provided and has an outer end 11. The rim 1 is shorter than the entire circumference of the lens L, and the outer ends 11 and 11 have a predetermined distance from each other.

Further, in the figure, what is indicated by the reference sign B is a bridge that connects the pair of rims 1.1 symmetrically, and what is indicated by the reference sign N · N is the nose suspended from the bridge B. The pad, which is designated by the reference numeral TT, is an ear hook temple foldably hinged to the tips of a pair of upper and lower split portions 2A and 2B described below.

A pair of upper and lower split portions, which are designated by reference numerals 2A and 2B, are made of a metal material and are elastically deformable. Each of the outer end portions 11 and 11 of the rim 1 is brazed to the outside. Have been combined. Each of the tip vicinity of the pair of upper and lower WariSatoshi portions 2A · 2B, along with interpolation hole 20A · 20B are opened, and each tip is one frame portion T ₁ and the hinge connection MimiKake temple T The proper hinge pieces 21A and 21B are formed. In the present embodiment, female holes corresponding to the rim lock screw 3 and hinge screw 4 described later are formed in the insertion hole 20B and the hinge piece portion 21B formed in the lower end piece split member 2B, respectively. There is.

Then, the rim lock screw 3 is inserted from above into the insertion holes 20A and 20B of the pair of upper and lower split portions 2A and 2B, and the rim lock screw 3 is screwed into the female screw portion of the insertion hole 20B. The upper and lower split portions 2A and 2B are screw-connected at their tip portions. As described above, the base end portions of the pair of upper and lower split portions 2A and 2B are brazed and joined to the outer end portions 11 and 11 with a predetermined interval, and by the screw connection by the rim lock screw 3, the upper and lower portions are connected. Between the base end portions of the pair of split portions 2A and 2B and the outer side surface of the lens L, a substantially triangular deformation allowable space S (see FIG. 1) is created, and in this state, the lens L is attached to the rim 1 It is held and fixed by.

In the present embodiment, since the hinge piece portions 21A and 21B are formed at both tip ends of the pair of upper and lower split portions 2A and 2B, the split portions 2A and 2B are connected to the rim lock screw 3 respectively. When they are fastened together, the hinge piece portions 21A and 21B form a hinge piece. The one piece piece T ₁ of the ear hanging temple T is fitted to this two piece piece of the hinge, and the hinge screw 4 is screwed into this fitting portion, whereby the split portions 2A and 2B of the present embodiment. An ear hook temple T is hinged to be freely foldable.

As described above, in the spectacle frame of this embodiment, since the deformation allowable space S is created between the split portions 2A and 2B and the outer surface of the lens L, the spectacle frame is externally attached to the spectacle frame. Even if external force is concentrated on the wisdom part due to the force applied from these, these split parts 2A and 2B support the concentrated external force by dividing it at the same time, and at the same time, these split parts 2A and 2B can be elastically deformed by the deformation allowance space S. Therefore, the external force is absorbed. Therefore, unlike the conventional product, the close proximity portion (near the outer surface of the lens) of the lens L is not damaged by the concentrated external force.

Further, in the spectacle frame of the present embodiment, since the deformation allowance space S exists in the outer surface portion of the lens L, the appearance of the intelligent portion is cleaner than that of the conventional product. In addition to the markedly improved design, the deformation allowance space S also expands the wearer's lateral field of view, resulting in an extremely good usability.
