    Flexible hinge that can extend outwardly the spectacle frame and method of manufacturing the same
    This invention belongs to the technical field of eyewear accessories, relating to a hinge which connects the foot to the frame, it designates a flexible hinge which can extend outwards the eyewear base and a method of manufacturing the same. .
    This flexible hinge includes a sling shell and a sling core. The sling shell is welded to the base of the glasses, the sling core is mounted on the edge of the glasses frames, the sling core is fixed in the sling shell to connect the glasses base with the glasses frames. The spectacle frames have a certain elasticity when the spectacle feet are open or closed due to the spring on the sling core. When the glasses' feet open, a small angle opens, extending outwards, to adapt to the wearer's head to allow more comfortable and firmer wearing.
    To prevent the sling core from falling after being inserted into the sling shell, in patent literature the document CN202306034U describes a structure of a sling core wedged in a sling shell, In this structure, a mounting groove is present in the sling shell and the central shaft of the sling core is provided with a mounting part, the mounting comprising the mounting sleeve and a clip fixed to the end of the mounting sleeve. The clip acts on the side wall of the mounting groove to prevent removal of the sling core. The drawback of this structure is that one end of the sleeve comes into contact with the spring, while the other end has no contact surface or structure to limit the position. So when the sling core is inserted into the sling shell, the extension clip on the mounting sleeve will be tight and start to contract. At the same time, an axial thrust is transmitted to the mounting sleeve, this thrust facilitates the sliding of the sleeve in the opposite direction of the spring. The consequence is the immobilization of the fastener between the sling core and the sling shell, which causes assembly problems. In addition, the contact area between the mounting sleeve and the axis of the sling core is low and its stability low. As the stability of the spectacle foot is poor after connection with the spectacle frame, the spectacle feet move or move easily, affecting the overall texture and performance of the spectacle.
    The object of this invention is to provide a flexible hinge which can extend the spectacle base outward and a method of manufacturing it, the hinge is assembled and structurally stable.
    The object of the present invention is achieved as follows: a flexible hinge which can extend the spectacle base, which comprises the sling shell and the sling core. The shell of the sling is welded into the base of the glasses; the sling core is fixed in the frame of the glasses; a mounting hole is disposed at one end of the sling shell, the sling core which is fixed in the sling shell is inserted into the mounting hole. The sling core includes a mounting seat and a central shaft; the mounting seat corresponds to the type of hole at the end of the mounting hole; the central shaft is fixed on the mounting seat and extends inside the mounting hole; a fixed tube and a spring are arranged on the central shaft; a stop is arranged at the end of the central shaft to prevent the spring and the fixed tube from falling. At least two barbs are arranged on the wall of the fixed tube, the barbs are elastic and can contract and expand, a clamping ring is arranged in the above mounting hole. When the fixed tube passes through the clamping ring, the barb contracts first, then expands outward and acts on the clamping ring to connect the sling shell to the sling core.
    Depending on the functions and effects of the clamping ring, it can be placed in the following two structures.
    First, the clamping ring is a circular groove, its inner diameter is greater than that of the mounting hole. When the sling core is inserted into the sling shell, the inner wall of the mounting hole tightens and retracts the barb. When the sling core crosses the circular groove, the barb expands outwards, the barb acts on the bottom or the wall of the circular groove to close the sling core on the sling shell.
    Second, the clamping ring is a convex ring ring, its inner diameter is smaller than that of the mounting hole, at the same time its inner diameter is larger than that of the central shaft which is equipped with a fixed tube and of a spring. When the sling core passes through the convex ring that compresses the barb, the barb contracts. Then the barb expands outward and acts on the surface or walls of the convex ring.
    Based on the technical diagram above, the following characteristics can also be achieved: the barb is cut in the wall of the fixed tube, a reduction hole corresponding to the barb is formed on the wall of the fixed tube, the pin can be mounted in the reduction hole. When it shrinks, it adapts to the reduction hole which is formed by stretching and expanding after being cut.
    Another improvement, the hole of the fixed tube is square, a corresponding convex shaft is placed on the central shaft, a square end face adapted to the tube hole is placed on the convex shaft. The sleeve of the fixed tube is arranged on the convex shaft, fixed to the central shaft, the fixed tube cannot rotate on the central shaft, which improves stability.
    As an additional improvement, two barbs are placed on the wall of the fixed tube, the barbs are located on the opposite wall of the fixed tube. The hole of the fixed tube is round, there are four barbs uniformly arranged on the wall of the tube, facilitating the installation of the fixed tube which is done without adjustment.
    A fixed wing with an end extending along the axis can be arranged on the wall of the fixed tube. A corresponding fixed slot is arranged on the mounting seat. The fixed wing can be clamped in the fixed slot which improves stability by preventing the fixed tube from rotating.
    According to an additional feature, the holes of the mounting seat and at the end of the mounting seat are square, which prevents the sling shell and the sling core from rotating towards each other.
    A method of making a flexible hinge that can extend the eyeglass foot outward is described below:
    Step 1. Select the relevant size profile, the profile is formed by stretching the mold to produce the sling shell;
    Step 2. The material plate is cut by laser, to produce the sling core according to the size of the product;
    Step 3. The barb is cut on the material plate by laser; after cutting to the specified size, it is rolled up to form the fixed tube, and then the barb is stretched in an expanded state;
    Step 4. We put the fixed tube on the central shaft of the sling core, then we put the spring; at the end, the end of the central shaft is embossed to form a stop;
    Step 5. The assembly of the parts is completed by inserting the sling core into the sling shell.
    The present invention has an important and beneficial technical effect compared to existing technology: the contact area between the fixed tube and the central shaft is large; the two ends are delimited so that it is not easy to produce an axial movement; when pressed or when it exerts a force against the sling shell, the barb has a stable base; during assembly, the barb can contract in the reduction hole to reduce the resistance of the sling core when it is inserted into the sling shell which facilitates assembly, saves time and energy ; furthermore, the connection between the fixed tube and the sling core is stable and there is no rotation between the fixed tube and the sling core; the connection between the sling shell and the sling core is stable and there is also no rotation between the sling shell and the sling core, which improves the stability of the glasses' feet when they open and close, without shaking, which improves the quality of the glasses and the wearing comfort of the glasses, and also extends the lifespan.
