Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glasses and relates to a pair of glasses legs. Background Art
[0002] Glasses are common optical devices in the prior art, and are especially indispensable for people with myopia and hyperopia in today's life. They generally include a combination of lenses and frames, and the frames can be divided into two parts: the frame and the temples.
[0003] There are two openings on the frame for installing lenses. The temples are connected to the two ends of the frame by hinges. The two temples can be flipped around the hinges to prop up or overlap with the frame, so that the glasses can be switched between use and storage at will.
[0004] As we all know, when a user wears glasses, the glasses are connected to the user's ears through the temples. However, the two sides of the user's head are not flat, but have a slightly convex or slightly concave shape. When the user wears glasses, for the former, the two temples will squeeze the two sides of the user's head, which will inevitably cause discomfort to the user in the long run. For the latter, it will cause the user to wear it loosely and the adaptability is poor. Summary of the Invention
[0005] The purpose of the present invention is to solve the above problems in the existing technology and to provide a pair of glasses legs. The technical problem to be solved by the present invention is: how to improve the adaptability of glasses.
[0006] The purpose of the present utility model can be achieved through the following technical solutions: a pair of glasses legs, comprising a main rod body at one end for hinged connection to the frame, characterized in that the pair of glasses legs also includes a secondary rod body in the form of an elongated strip, the other end of the main rod body has a hinge groove, the side wall of the secondary rod body close to the front end has a hinge plate, the hinge plate is embedded in the hinge groove and hinged to the main rod body, the rear end of the secondary rod body can be flipped inward relative to the main rod body so that the front end of the secondary rod body abuts against the side wall of the main rod body, and the rear end of the secondary rod body can be flipped outward relative to the main rod body so that the hinge plate abuts against the bottom wall inside the hinge groove.
[0007] The eyeglasses of the present invention are characterized in that the main rod and the auxiliary rod are hingedly connected in a manner that replaces the single integrated eyeglass temple in the prior art. When the glasses are assembled, the main rod serves as the main supporting component, and its front end is hinged to the eye frame through the temple wire. For the eyeglass temple disclosed in the present application, a hinge groove is provided at the rear end of the main rod, and a hinge plate is provided on the side wall of the auxiliary rod near the front end. The hinge plate is embedded in the hinge groove and hinged by screws, so that the auxiliary rod can be flipped inward or outward relative to the main rod. When worn, the auxiliary rod can replace part of the main rod to contact the user's facial skin. When the width of the user's head is greater than the distance between the two eyeglass temples, the auxiliary rod is subjected to an outward pushing force. Driven by this force, the auxiliary rod can swing the rear end outward around the hinge to increase the distance between the two auxiliary rods, thereby minimizing the pressure applied to the side face of the user. On the contrary, when the user's head is wider than the distance between the two eyeglass temples, the auxiliary rod is subjected to an outward pushing force. Driven by this force, the auxiliary rod can swing the rear end outward around the hinge to increase the distance between the two auxiliary rods, thereby minimizing the pressure applied to the side face of the user. When the width spacing between the two temples is smaller than the spacing between the two temples, the rear end of the auxiliary rod body resting on the ear can be pressed by the ear to swing inward relative to the main rod body, so that the auxiliary rod body is firmly against the user's face, thereby ensuring the adaptability of the glasses to different users and ensuring comfort of use. It is worth mentioning that the auxiliary rod body has a stop point relative to the main rod body whether it swings inward or outward. Specifically, when swinging outward relative to the main rod body, when the hinge plate and the groove wall of the hinge groove abut against each other, the groove wall at the hinge restricts the hinge plate, thereby limiting the outward swinging amplitude of the auxiliary rod body from being too exaggerated, ensuring the adaptability of the glasses while ensuring the stability of the user when wearing them. Conversely, when swinging inward relative to the main rod body, the front end of the auxiliary rod body can abut against the side wall of the main rod body, and the front end of the auxiliary rod body is supported by the side wall of the main rod body, thereby ensuring the overall structural stability of the temple in the current state, and further ensuring the stability of the user when wearing it.
[0008] In the aforementioned temple, the rear end of the main rod has two protrusions spaced apart along its width, the hinge slot is formed between the two protrusions, and the side surfaces of the hinge plate engage with the two protrusions. The hinge slot is formed by the two protrusions enclosing each other, and after being inserted into the hinge slot, the two protrusions constrain the hinge plate on both sides, thereby preventing the hinge plate from moving between the two protrusions during subsequent use, thereby ensuring the stability of the overall structure of the temple.
[0009] In the aforementioned temple, a curved receiving groove is defined on the sidewall of the secondary rod near the front end, the hinge plate is formed on the wall of the receiving groove, and the outer walls of the two protrusions abut against the inner wall of the receiving groove. This arrangement allows the secondary rod to swing inward or outward relative to the main rod, while not only being restricted by the screw at the hinge, but also guided by the abutment between the two protrusions and the wall of the receiving groove, ensuring smooth rotation and reducing the force applied to the screw, thereby extending the service life of the temple and, ultimately, the entire pair of glasses.
[0010] In the aforementioned eyeglass temple, the sidewall of the secondary rod, facing away from the main rod, is provided with a first elastic buffer pad and a second elastic buffer pad, both of which are elongated strips. The first elastic buffer pad is positioned near the front end of the secondary rod, while the second elastic buffer pad is positioned near the rear end of the secondary rod. The first elastic buffer pad and the second elastic buffer pad replace the sidewall of the secondary rod in contact with the user's facial skin, utilizing their own material properties to relieve the pressure exerted by the secondary rod on the user's skin, thereby improving user comfort.
[0011] In the aforementioned eyeglass temple, a third elastic buffer pad is provided on the sidewall of the secondary rod facing the main rod, and the third elastic buffer pad is positioned near the front end of the secondary rod. The second elastic buffer pad replaces the contact between the front end of the secondary rod and the sidewall of the main rod, and the material properties of the second elastic buffer pad relieve the interaction force between the main rod and the secondary rod, thereby preventing damage caused by excessive interference between the main rod and the secondary rod.
[0012] Compared with the existing technology, this glasses leg has the following advantages:
[0013] By arranging a hinge plate on the outer side wall of the auxiliary rod body near the front end and arranging a hinge groove at the rear end of the main rod body, the hinge plate is embedded in the hinge groove and hinged to the main rod body through screws. When in use, according to the head width of different users, the auxiliary rod body is swung inward and outward relative to the main rod body around the hinge to ensure that the distance between the two glasses legs is consistent with the user's head width, and to avoid the glasses legs from pressuring the user's face, thereby ensuring the adaptability of the glasses and the comfort of the user.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0021] like Figure 1 As shown, the glasses include a frame, a Figure 2 The glasses leg comprises two main rods 1, the front ends of the two main rods 1 are hinged to the two ends of the frame through the foot wires, and the glasses leg also comprises two auxiliary rods 2, combined with Figure 4 On the rear end side walls of the two main rod bodies 1, two protrusions 12 are provided along the width direction thereof, and a hinge groove 11 is formed between the two protrusions 12. Figure 5 On the outer side wall of the auxiliary rod body 2 near the front end, there is a hinge plate 21 protruding outward. The hinge plate 21 is embedded in the hinge groove 11. The screws are passed through one of the protrusions 12, the hinge plate 21 and the other protrusion 12 in sequence, so that the main rod body 1 and the auxiliary rod body 2 are hinged together.
[0022] like Figure 5 As shown, an arc-shaped receiving groove 22 is provided on the outer side wall of the auxiliary rod body 2 near the front end, and the hinge plate 21 is formed on the groove wall of the receiving groove 22. When the hinge plate 21 is embedded in the hinge groove 11, the two protrusions 12 are embedded in the receiving groove 22 and abut against the groove wall of the receiving groove 22.
[0023] like Figure 5 As shown, an elastic buffer pad 1 23 is integrally formed at the front end of the side of the auxiliary rod body 2 facing away from the main rod body 1, and an elastic buffer pad 2 24 is integrally formed at the rear end, and an elastic buffer pad 3 25 is integrally formed at the front end of the side of the auxiliary rod body 2 facing the main rod body 1. It is worth mentioning that the elastic buffer pad 1 23, the elastic buffer pad 24 and the elastic buffer pad 3 25 are all made of rubber material. As an alternative, silicone material can also be used as a replacement.
[0024] Principle of use: the user flips the temples of the glasses relative to the frame and opens them, so that the two temples are rotated outward and propped up. In this state, the two temples are overlapped on the ears and rest against the bridge of the nose through the nose pads on the frame. On this basis, the auxiliary rod body 2 replaces part of the main rod body 1 to rest against the user's face. When the width of the user's head is greater than the distance between the two auxiliary rod bodies 2, the auxiliary rod body 2 rotates around the hinge to make the rear end flip outward by a certain degree. Conversely, when the width of the user's head is greater than the distance between the two auxiliary rod bodies 2, the auxiliary rod body 2 rotates around the hinge to make the rear end flip inward by a certain degree, so that the side of the auxiliary rod body 2 facing away from the main rod body 1 is always in contact with the user's face through the elastic buffer pad 1 23 and the elastic buffer pad 2 24, so as to ensure the adaptability of the glasses frame to different users, and for users with slightly larger head width, avoid the temples from causing long-term pressure on their facial skin, thereby ensuring comfort of use.
[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
[0026] Although this document frequently uses terms such as main rod 1, hinge slot 11, protrusion 12, auxiliary rod 2, hinge plate 21, receiving slot 22, elastic buffer pad 1 23, elastic buffer pad 2 24, and elastic buffer pad 3 25, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
