Abstract

(57) [Summary] [Purpose] The position of the lens of the eyeglass is changed with respect to the eye. [Structure] Insert the coil spring into the tube with the hook groove,
While pushing the arm into the tube, hook the protrusion on the arm into the hook groove to prevent the arm from falling off.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a height-adjustable pad, and by using the pad of the present invention, the center position of the optical axis of the lens can be moved with the glasses kept in the same state.

[0002]

[Prior Art]

 Normally, a person's line of sight is downward when he / she is near, and upward when he / she is far. However, the position of the optical axis center of the correction lens does not move on the lens, so if the lens position does not change with respect to the face, the visual axis and the optical axis will not match between near work and far work, which is difficult. I think.

However, most of the current eyeglasses are made by fixing the lens in a fixed position, and if you still want to move the position of the center of the optical axis of the lens, slide the eyeglasses over the nose. It does not exist. However, if you actually wear the glasses while sliding them, the pad will hit a strange position, and the temples will not fit the length to your ears, making it very uncomfortable to wear.

[0004]

[Problems to be solved by the device]

 Therefore, it is an object of the present invention to change the position of the optical axis center of the lens without shifting the eyeglasses so that it can be used for both distant work and near work.

[0005]

[Means for Solving the Problems]

 According to the present invention, a hook-shaped groove is provided on the pipe surface of the pad arm holding pipe attached to the rim portion of the eyeglass frame, a mating protrusion is provided on the pad arm of the pad body, and a coil spring is provided on the pad arm holding pipe. Insert the pad arm of the pad body into the pad arm holding tube, and while the coil spring urges the pad arm toward the insertion opening, the meshing protrusion of the pad arm becomes a hook-shaped supporting groove. The above problem was solved by adopting a means of fixing the pad main body by being bitten.

[0006]

【Example】

 Hereinafter, the present invention will be described based on embodiments.

The pad arm holding tube 1 is attached to a predetermined portion of the rim of the spectacle frame. This holding tube 1 has a bottom hole closed by a screw 13 screwed into a lower hole when attached to a rim, and has two hook-shaped supporting grooves 12 and 12 from the upper hole. It has a groove 11 to hold.

A coil spring 2 is inserted into the pad arm holding tube 1. Further, the pad arm 31 is also inserted after the coil spring 2. The pad arm 31 is connected to the pad box of the cleaning pad to form the pad body 3, and also has a meshing protrusion 32 at a predetermined portion, and the protrusion 32 is inserted along the groove 11 of the pad arm holding tube 1. .. Now, when the pad arm 31 is inserted into the holding tube 1 and then twisted slightly, the engagement protrusion 32 enters the hook-shaped supporting groove 12, and at the same time, the pad arm 31 is urged upward by the coil spring 2. , The pad arm is fixed so that it does not come off.

After that, when the entire assembled spectacles are hung on the face, the pad supports the front part of the spectacles from below on the face, and the pad arm holds the holding tube between the pad arm and the pad arm holding tube. The force is applied so that it may come out. However, due to this force, it is natural that the meshing protrusions hit the dead end of the hook-shaped supporting groove and the pad arm cannot be pulled out.

Since the hook-shaped support groove is provided in two steps, if the support groove into which the engaging protrusion of the pad arm engages is changed, the amount of insertion of the pad arm into the pad arm support tube changes, and The position of the front part changes when the glasses are put on the face. As a result, the position of the optical axis center of the lens changes for near work and for far work.

In the above embodiment, the screw is screwed into the bottom of the support tube to hold the spring, but the support tube may have a bottom or a step from the beginning.

[0012]

[Effect of the device]

 As described above, by using the pad of the present invention, it is possible to handle distant work and near work while wearing glasses at the optimum position. Therefore, the pad of the present invention is very convenient.
