Description

Technical Field

[0001] This invention relates to a connecting unit for eyeglass frames, for easily and quickly connecting the front of the eyeglass frame to the temple, and to an eyeglass frame itself. In particular, this invention relates to an improved connecting member for eyeglass frames made of metal. Background Technology

[0002] In the prior art, it is common practice to use various types of hinges made of plastic and / or metal to rotatably connect the temples to the front of the frame, allowing the temples to pivot relative to the front of the eyeglass frame with the lenses fitted. Commonly known are screw-type joints or joints achieved through a rotatable direct connection of connecting elements.

[0003] For example, an eyeglass frame is known from patent document WO 2005 / 109081 A2, which includes a front portion for securing lenses in place and temples hinged to the front portion via screwless hinges. A portion of the hinge is slidably engaged in the other portion, wherein the temple has at least one spring tongue that cooperates with a sliding surface of the front portion of the frame.

[0004] An eyeglass frame is known from patent document EP 1023626 B1, which includes a front portion and a pair of temples connected to the front portion by hinges, the hinges ensuring proper connection without pins or screws. In this case, the temples have extensions at their ends on the sides of the frame, wherein the extensions are coiled such that they form tubes that fit into corresponding holes in the frame.

[0005] A hinged eyeglass frame is known from patent document US 2022 / 0179235 A1, which has a front, a pair of temples and a pair of hinges, the pair of hinges being configured to ensure a pivotal connection between each temple and the front of the frame, wherein each hinge includes a pin with a wedge-shaped end and a means for blocking movement of the temple.

[0006] A hinge for an eyeglass frame is known from patent document EP 2 963 481 A1, which connects the front of the frame and the temple. The hinge includes a first element, one of whose ends is given a leaf shape with a bearing edge, and wherein its end edge is obliquely oriented relative to the bearing edge, and it includes a fastener. The hinge includes a second element having a groove whose width corresponds to the thickness of the leaf. Furthermore, the hinge includes a flexible cap having a crossbar disposed within the fastener and at least one arm additionally anchored in the second element. The crossbar tends to press the first element into the groove, wherein the first and second elements can pivot relative to each other between an open position and a closed position.

[0007] A metal eyeglass frame is known from patent document PL 210490 B1, which includes a shaped ring with fittings, in which a longitudinally through opening is formed at one end on the side of the lens. The fitting has an extension in the form of a connector, with a plug engaging a socket on the side, wherein the socket is in the form of a sleeve-shaped fold at the end of a flat rod. A resilient strip with a socket is fitted between the flat rods, in which the temple is blocked in a closed position. The flat rods and the strip, along with the temple, form two homogeneous sub-units, all of which are made from a thin sheet of metal during the stamping process. The same process is used to manufacture the sub-units stamped from a thin sheet of metal, which includes the shaped ring of the fitting and the connector. Summary of the Invention
