Description

  The present invention relates to an insert for a spectacle frame pad or nose pad.

  Eyeglasses are usually a frame composed of two groove lines (rims), a frame that functions to hold the lens in an appropriate position, a bridge that connects the two groove lines, and a projection that protrudes from the bridge. It consists of two flexible pads or nose pads that are connected to the bridge by rigid inserts and two hinges that are hinged to the channel.

  Currently, the nose pad is formed from a substantially flexible plastic material so that it can rest comfortably at the base of the nose and is given a teardrop-like shape with a rounded top facing down It has been known.

  The nose pad insert is known to be formed from a metal material or hard plastic material so that the nose pad can be connected to the bridge of the spectacle frame, and the insert is made of metal material or hard plastic It consists of a flat appendage formed and embedded in the nose pad and a shank protruding from the appendage. The shaft portion is attached to the pad holder, and the pad holder can be attached to the spectacle frame.

  In order to improve the conformity to the shape of the base of the nose, the connection between the pad holder and the shaft part is usually pivoted laterally with the pad holder in the shaft part in order to allow the nose pad to swing. It is done by supporting.

  However, such conventional means have the following problems. In other words, the swing of the nose pad is actually limited to one plane, and the rotation angle given to the nose pad is also limited, so that the nose pad can be applied to various shapes and structures at the base of the nose of various users. There is a problem that it cannot be optimally adapted.

  Further, the conventional means also has a problem that abnormal noise is generated by the pad or nose pad when the glasses are swung. Even if this noise is reduced, when the spectacle frame is swung, the pad or nose pad of the conventional system is still movable, which still produces a certain amount of noise. This abnormal noise is because the pad insert collides with the wall surface of the pad holder.

  In high-grade glasses, such abnormal noise is bothersome for the user and impairs the willingness to purchase.

  The goal of the present invention is to provide an insert for a spectacle frame nose pad that allows the user to optimally adapt the nose pad to various shapes and structures at the base of each user's nose, thereby eliminating the aforementioned problems. It is to eliminate.

  Within this goal, the object of the present invention is to obtain an insert that can limit the noise between the pad or nose pad and the pad holder when the spectacle frame is swung.

  Another object is to provide an insert that is simple in construction and low in cost and can be made by conventional conventional systems.

  This goal, which will become more apparent below, and the other objects mentioned above, is a rigid insert for a flexible pad or nose pad of a spectacle frame, wherein the rigid insert for a flexible pad or nose pad is as follows: Achieved by: Such an insert comprises a shank partially embedded in the flexible pad or nose pad, the free end of the shank having two opposite first hemispherical sides and two opposite orientations The second flat side surface of the pad holder is substantially rectangular (hereinafter referred to as “rectangular shape”) in plan view, and the shaft portion can be connected to a pad holder having a complementary shape. Can be attached to the frame of the spectacle frame and has a pair of first side walls, wherein the pair of first side walls are friction controlled and the two oppositely opposed first side walls It is characterized by being pivotally supported on one hemispherical side surface.

  Further features and advantages of the present invention will become more apparent from the detailed description of specific embodiments of a nose pad according to the present invention, but not exclusively, which are given by way of non-limiting example in the accompanying drawings.

  In the embodiments described below, individual features shown in connection with specific examples may actually be replaced with other different features present in other embodiments.

  Referring to the figures, reference numeral 1 generally refers to a rigid insert substantially formed from a metallic material or rigid plastic, which can be connected to a teardrop-like flexible pad or nose pad 2. .

  The insert 1 comprises a flat appendage 3, which preferably has an elliptical shape in plan view, or a shape with a smaller dimension, similar to the shape of the nose pad 2. It is embedded in the nose pad 2.

  A shaft portion 4 projects from the attachment portion 3 to the outside of the nose pad 2, and the free end 5 of such a shaft portion has a rectangular shape in plan view, and two first hemispheres opposite to each other. Side surfaces 6a, 6b and two opposite flat second side surfaces 7a, 7b.

  The shaft portion 4 can be connected to a pad holder 8 having a complementary shape. The pad holder 8 is constituted by an open subframe having a rectangular shape in plan view so as to define the rear wall 9. The rear wall 9 is connected to the frame of the spectacle frame by a wire 10, and a pair of side walls 11a and 11b are branched from the rear wall 9, and they are connected to a pair of front side appendages 12a and 12b. The appendages 12a and 12b are located on the same surface with their free ends facing each other.

  Accordingly, the pad holder 8 has an open shape structure that is not closed, in which a certain amount of play is allowed between the free ends of the pair of front appendages 12a, 12b facing each other, thereby A connection with the frictionally controlled shaft 4 can be achieved.

  The inner side surface 13 of the rear wall 9 and the inner side surfaces 14a, 14b of the pair of front appendages 12a, 12b are complementary to the second flat side surfaces 7a, 7b opposite to each other. It faces in the direction of the second side surface 7a, 7b.

  The inner side surfaces 15a and 15b of the pair of side walls 11a and 11b have complementary shapes to the first hemispherical side surfaces 6a and 6b opposite to each other so as to contact the first side surfaces 6a and 6b. Is arranged.

  The operation is as follows. The insert is complementary to the first hemispherical side surfaces 6a and 6b opposite to each other, and is disposed inside the pair of side walls 11a and 11b so as to be in contact with the first side surfaces 6a and 6b. As shown in FIGS. 6 to 16, the friction that can move the nose pad 2 in multiple directions with a high displacement factor that greatly exceeds what can be achieved conventionally as shown in FIGS. A controlled connection is obtained.

  The opposing free ends of the pair of front appendages 12a, 12b are actually based on the desired movement imparted to the nose pad, with the connection between the pad holder 8 and the shaft 4 maintained. The distance between the free ends can be changed.

  Accordingly, the nose pad 2 is movable in different directions and in different planes, and at the same time, does not fall off the pad holder 8.

  For example, the rotation shown in FIGS. 6 and 7 can be about 8 degrees, for example, the rotation shown in FIGS. 8 to 11 can be about 12 degrees, as shown in FIGS. The rotation can be about 8 degrees.

  Accordingly, the present invention fully achieves the intended goals and objectives and provides a wide adjustment range for the position of the nose pad relative to the pad holder, thereby providing a nose pad for various shapes and structures at the base of each user's nose. It has been found that an insert 1 for a spectacle frame nose pad 2 can be obtained that can be optimally adapted.

  Furthermore, the insert can limit noise between the pad or nose pad and the pad holder when the spectacle frame is swung.

  Finally, the insert is structurally simpler, less expensive, and generally known systems can be applied.

  The present invention is susceptible to numerous modifications and changes, all of which are within the scope of the appended utility model registration claims.

  Of course, the materials used and the dimensions of the individual components of the present invention may be more relevant depending on the specific requirements.

  Depending on whether it is advantageous or convenient, the features described above may also be deleted or replaced by equivalent features.
