Description

[Detailed description of the invention] The present invention relates to a spring-loaded hinge for the edge of a spectacle case.

In general, the temples of Meganebo are designed so that they can be used while being held in place without slipping along the nose.
It must be held by some kind of elasticity almost at right angles to the edges.

However, practical problems arise in realizing this. That is, existing conventional hinges are typically attached to the temple by soldering, so if one member of the temple or hinge breaks, the entire assembly must be replaced when using that mechanism. There are drawbacks.

Furthermore, French Patent No. 2,485,212 was considered as having the above-mentioned mechanism. This patent shows a hinge for attaching the temple of the spectacles to the corresponding edge, which can maintain a stable position of the temples in the folded position for storing the spectacles and in the open position for hanging them; Similarly, beyond its open position, the temple can also be opened elastically. This hinge has a cylindrical space formed in a metal member to which the temple is attached, and a slider having a coaxial through hole is disposed in the cylindrical space, and the slider is shorter than the coaxial through hole and has a spring therein. a block is formed with a longitudinal groove and is fixed to the metal member by screws and closes off the cylindrical space, and is attached to the edge and pivots about an axis perpendicular to the spring; It has a hinge support mounted in such a way.

Thus, when the temple is in its open position, it is held stable by said spring.
A spring compresses to bring the temple into its stable closed position, and the metal member overcomes the spring action to rotate the temple in one direction without having to come into direct contact with the edge.

When opening the temple, the temple is rotated in the opposite direction until the slide enters into contact with the block. Since its maximum expansion position is unstable, the vine returns to its initial position as soon as the spring is relaxed.

However, such prior art does not provide any details regarding the setting of the temples, which must be articulated to the surface of the edge of the spectacle redoubt, or how to assemble the temples with the reinforcing metal layer to the section with the stronger section. There is a problem that there is no description.
