Description

Nose pad and glasses with same {NOSE PAD AND A PAIR OF SPECTACLES THEREWITH}

The present invention relates to a nose pad and glasses having the same, and more particularly, to minimize sliding of the wood pad in a lowering operation to improve the sliding state, and to use the repulsive force of the magnet member to set the nose pad to a predetermined position. The present invention relates to a nose pad and glasses provided with the same, which move and maintain the state moved to the set position by the repulsive force.

To date, there have been many attempts to raise and lower the spectacle lenses in front of the user's eyes so that the lenses of two or more different focal regions can be moved and escaped to the desired use position.

In particular, as shown in Figs. 1 and 2, in U.S. Patent No. 5,691,796, a pair of upper magnets 50l and 50r and a pair of lower magnets 54l and 54r are formed at the upper end of the nose pads 26l and 26r. And a structure fixed to each of the lower ends has been proposed.

The nose pads 26l and 26r include cylindrical bores 46l and 46r, respectively, of a circular cross section.

Then, the pair of sliding members 34l and 34r are fixed to the pair of pad supporting arms 30l-one for convenience only, in the same shape.

These sliding members 34l and 34r have a circular cross section so that they can be moved smoothly in cylindrical bores 46l and 46r.

A pair of movable movable magnets 44l and 44r are fixed to the respective sliding members 34l and 34r.

Therefore, the nose pads 26l and 26r are raised or lowered as the movable magnets 44l and 44r are attached to the corresponding upper magnets 50l and 50r and the corresponding lower magnets 54l and 54r. Will be maintained.

At this time, the sliding members (34l, 34r) is guided to move along the guide rails (48l, 48r) formed on the edge of the cylindrical bore (46l, 46r).

On the other hand, the pair of nose pads 26l and 26r are connected to the bridge 28.

In particular, the distance between the upper end of the right nose pad 26r and the upper end of the left nose pad 26l is different from the distance between the lower end of the right nose pad 26r and the lower end of the left nose pad 26l.

Therefore, when the pair of nose pads 26l and 26r are lowered, the nose pads 26l and 26r are opened laterally, and thus the nose pads (26) due to the force of the bridge 28 to return to its original state by the elastic restoring force. 26l, 26r) itself downward movement is hindered.

Then, when the pair of nose pads 26l and 26r are raised, the nose pads 26l and 26r move toward each other due to the friction between the sliding members 34l and 34r and the guide rails 48l and 48r. Pressurized.

This friction causes upward movement of the nose pads 26l and 26r, thereby hindering downward movement of the glasses themselves.

Thus, as shown in FIGS. 3 to 5, in Korean Patent Registration No. 0504260, a structure capable of smoothly moving lenses of two or more different focal regions to a desired use position has been proposed.

That is, the spectacle frame 12 is a frame 14 made up of a pair of elliptical rims 14l and 14r connected by a bridge 16 and a pair of glasses turning at one end of the corresponding rims 14l and 14r. The legs 18l and 18r are included.
