Description

Hinge for spectacles

Technical field

The utility model relates to glasses, sunglasses or with glasses the protective glasses, particularly their hinge (G02C5/22) of same characteristic is arranged.

Background technology

After the glasses utility model, mirror holder, eyeglass all constantly have significant development, but the development of hinge for spectacles is just very different.Up to now, though the patent light of hinge for spectacles just surpasses 200 in the U.S., its function is pitiably little.For example, modal hinge for spectacles function is exactly to allow the mirror pin can freely do the folding of 90 degree.The more advanced mirror pin that just can allow can flexibly be parked in two on the opening and closing positions of 90 degree, more advanced again the mirror pin that also just makes still maintains certain elasticity to clamp head on complete open position, certain clamping force is also arranged when glasses are moved on the crown.

The earliest glasses (sunglasses especially, down together) way of shifting onto on the crown is to appear on the sunbath sandy beach, because this moment, the man bared the upper body, the woman also has only minimum brassiere, when temporarily without glasses, do not have the place can place glasses on one's body, have only it has been pushed to head upward.Much less, do being easy to make glasses to fall on the ground like this, and the method for so temporary placement glasses can't be accomplished for most of men.For example, when this man's hair is rare, head will do bigger pitching action or put on and take off when more frequent, and glasses are got off by landing on the head.For this reason, the someone wishes the glasses that temporarily take off are hung on the neck, but because neck than thin, therefore connects a strap between two earpieces, whole pair of glasses just hang on the neck by belt when glasses are temporarily taken off.Be made in like this when wearing uncomfortable, very inconvenient especially for the woman that long hair is arranged.

Want to make glasses directly to hang on the neck by the mirror pin, the equivalent angle that must make mirror pin and picture frame like this, will be set up the intermediate range fixed position less than 90 degree in the middle of the folding angle of mirror pin 90 degree.Up to now do not find disclosing of this technology.

Summary of the invention

The purpose of this utility model is a kind of new technology of exploitation, make earpiece except terminating in two on the extreme position of 90 degree opening and closing, can also terminate in and be positioned on the middle several fixed positions of this 90 degree (so-called intermediate range is fixed), like this, object is auxiliary just to make glasses only depend on the mirror pin to hang on the neck without any need for adding.

In order to achieve the above object, hinge for spectacles of the present utility model mainly comprises: one is contained in the not hinge plate that has ratchet of moved end; One and the coaxial mounted cam bit that has stop means of above-mentioned hinge plate, cam bit include the cocked bead that can hide ratchet and can expose the notch edge of ratchet, and the relative position of cocked bead and notch edge and ratchet changes with the rotation of cam bit; A hinge plate that is contained in the moved end, this hinge plate have engageable elastic pawl in ratchet, and can drive the drive unit that cam bit rotates by stop means.

When the mirror pin was inwardly amounted to by the position of standard-sized sheet, the elastic pawl on the hinge plate of moved end can be absorbed in the ratchet of moved end hinge plate not, and the mirror pin that has ratchet this moment just can not be to opening the direction motion, and can only move to amounting to direction.When ratchet continues inwardly motion through each ratchet successively, drive unit on the hinge plate drives cam bit by stop means and rotates, make the cocked bead of this cam bit cover in ratchet, so as the mirror pin by amount to the position when opening the ratchet on the mirror pin can not be absorbed in the ratchet.When the mirror pin is outwards drawn back by the position of amounting to, after the ratchet on the mirror pin passes through each ratchet, drive unit on the mirror pin hinge plate drives the cam bit backward rotation by stop means, make the notch edge of this cam bit expose ratchet, thereby realize in the ratchet that intermediate range fixes so that the mirror pin can be absorbed in by fully open position ratchet on the mirror pin when amounting to the position motion.

The used part of the utility model is few, make simple, can be in the process of amounting to the angle of fixed mirror pin and picture frame easily, make picture frame and two mirror pin form the triangle or the polygon of suitable angle, so that whole pair of glasses directly hang on the neck, this function is not seen before, is applicable to that the glasses manufacturing taps new markets.
