Abstract

An anti-slip pad having a serrated contact surface made of a rubber elastic body is integrally attached along a wearing contact surface near a tip cell or ear hook part of a temple of a spectacle frame in order to suppress a slip of the spectacles. The contact surface induces a reaction force of elastic restoration due to the wearing contact pressure, restrains the temple from moving forward, maintains the wearing contact state of the nosepiece of the glasses frame, and wears the wearing load of the glasses. It is an object of the present invention to provide a misalignment stopper for spectacles that is shared and supported by a nose pad and a pad.
The present invention relates to a rubber elastic body in which a large number of sawtooth tips 2c are molded forwardly in the spectacle frame 1 along the wearing contact surface extending from the tip cell 2d of the temple 2 to the ear hooking portion 2a to the middle of the temple. The misalignment stop pad 2b having the contact surface is integrally mounted to constitute a misalignment stopper, thereby solving the problem.

Description

  The present invention relates to a means for suppressing the displacement of glasses.

  When setting the wearing value of glasses, the pupil position is set through the optical front adjustment of the front, the plane adjustment of the temple, and the side adjustment as a necessary condition of the frame function. It is also necessary to adjust the wear contact surface of the front cell to a uniform wear contact pressure without any sense of incongruity, but the nosepiece has a limited wear contact area due to lens optics and wear appearance. The load on the glasses by its own weight, that is, to support the wearing load, the contact pressure of the nose inevitably increases, and the support function of the load tends to be insufficient. There is a tendency to cause a deviation between the optical axis of the lens and the line of sight of wearing, that is, a deviation.

  As a problem to be solved by the present invention, a pad having a serrated contact surface of a rubber elastic body is provided along a wearing contact surface in the vicinity of the tip cell or ear hook portion of the temple of the spectacle frame in order to suppress the slippage of the spectacles. The wearing contact pressure of the contact surface of the pad induces a reaction force of elastic recovery of the pad, restrains the temple from moving forward and maintains the wearing contact state of the nosepiece of the spectacle frame, It is intended to provide a misalignment stopper for spectacles in which a wearing load is shared and supported by a nose pad and a pad.

  In order to achieve the above object, the eyeglass misalignment stopper of the present invention is a spectacle frame in which a plurality of sawtooth tips are directed forward along the wearing contact surface extending from the tip cell of the temple to the ear hanging part or halfway through the temple. A slip-off pad having a contact surface of a molded rubber elastic body is attached, and when wearing spectacles, the reaction force of elastic restoration against the elastic strain of the sawtooth tip group due to the contact pressure of the contact surface is induced, and the temple To prevent the eyeglass frame from falling off by holding the eyeglass frame nosepiece in contact with the nosepiece and supporting the load on the eyeglasses with the nosepiece and the displacement stop pad. It is said.

  The eyeglass displacement stopper of the present invention has a displacement stopper pad having a contact surface of a rubber elastic body in which a large number of sawtooth tip groups are arranged forward along the wearing contact surface near the ear hook portion of the temple. When wearing spectacles, by inducing a reaction force of elastic recovery against the elastic strain of the sawtooth tip group due to the wearing contact pressure of the contact surface, restraining the forward displacement of the temple, The wearing contact state can be maintained, and the wearing load of the glasses can be shared and supported by the nosepiece and the misalignment stop pad to suppress the omission of the misalignment of the glasses.

  And, the reaction force of elastic restoration against the elastic strain of the sawtooth tip group due to the contact pressure of the contact surface of the slip stopper pad is induced, the temple is urged to be displaced rearward, and the load of the spectacle hanging weight is shifted. It can be shared and supported by the nose pads, and the wear contact pressure can be reduced by reducing the wearing contact pressure.

  In addition, the stopper pad has a contact area that extends from the tip cell of the temple to the ear hooking part or in the middle of the temple with a rubber elastic body having a low hardness, so that the contact area is set sufficiently large to prevent the glasses from slipping off. The necessary and sufficient wearing contact pressure can be suppressed to a minute pressure that does not cause discomfort.

  Furthermore, in the wearer's behavior, the contact surface saw blade tip group with respect to changes in the wearing contact pressure due to the acceleration or load factor variation related to the hanging weight of the spectacle frame due to the fine movement of the temple, the tilting of the head and the movement of the body position. It is possible to amplify the reaction force of the elastic restoration to promote the displacement of the temple in the rear direction and amplify the effect of preventing the slipping off.

  In order to suppress the slippage of the glasses, in the glasses frame, along the wearing contact surface extending from the tip cell of the temple to the middle of the ear or the middle of the temple, a slip pad having a serrated contact surface of a rubber elastic body is attached, The contact surface of the pad was realized by inducing a reaction force for elastic restoration by wearing contact pressure and restraining the forward displacement of the temple.

  1 to 3, in the eyeglass frame 1, a rubber elastic body in which a large number of sawtooth tips 2c are formed in a forward direction along the wearing contact surface extending from the tip cell 2d of the temple 2 to the ear hooking portion 2a to the middle of the temple. A slip-off stop pad 2b having a contact surface is integrally attached, and when wearing spectacles, a reaction force for elastic restoration against elastic strain of a sawtooth tip group due to wearing contact pressure of the contact surface is induced, and the temple The frontal displacement of the eyeglass frame is restrained, the wearing contact state of the nosepiece of the spectacle frame is maintained, and the wearing load of the spectacles is shared and supported by the nosepiece and the misalignment pad to prevent the omission of the misalignment of the glasses. I am going to do that.

  FIG. 2 is a perspective view of the main part in the vicinity of A in FIG. 1 and in the vicinity of the ear hooking part 2a of the temple 2, and shows the shape and positional relationship of the low-rubber elastic elastic displacement pad 2a. Is a cross-sectional view taken along the line BB in FIG. 2, and shows an embodiment in which a displacement stop pad 2 b having a contact surface having a group of sawtooth tips 2 c formed forward is attached to the temple 2 integrally. It is recommended to apply natural rubbers and elastomers such as silicon rubber as the rubber elastic body having low hardness. In addition, the displacement prevention pad 2b may be a method of bonding and updating as a separate component, instead of the method of attaching the temple integrally to the temple.

  In the embodiment shown in FIG. 4, in the temple 2 of the spectacle frame 1, a rubber elastic body tube 2 e having a low hardness is fitted in a close contact manner from the leading cell 2 d to the middle of the temple in the vicinity of the ear hooking portion 2 b in a close-fit manner. The tube is integrally attached with a stopper pad 2b having a contact surface in which a large number of sawtooth tip groups 2c are formed facing forward on the wearing contact side of the temple, and if necessary, together with the tube An insertion / removal update method may be used.

  The present invention is applied to a means for preventing misalignment that is formed integrally with a temple of a spectacle frame, and is used for a misalignment stopper as a component that can be reattached / removed according to the degree of movement of the wearer. It can also be applied to applications.

  It is a perspective view of the spectacles frame which comprises the shift stopper of the spectacles of this invention.
