Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, specifically to an adjustable eyewear structure that adapts to facial contours. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or as a fashion accessory. Currently, eyeglasses are worn by placing the bridge of the frame on the wearer's nose for support, with temples extending to the ears for further securing.

[0003] The traditional eyeglasses have a rigid structure and can only be adapted to different users' facial features through soft nose pads and the opening angle of the temples.

[0004] For example, the angle between the eye socket and the bridge of the nose varies from person to person. Although the frame is pre-curved, the difference in angle can cause the gap between the wearer's eye socket and the frame to be too large or too small, resulting in discomfort.

[0005] The contours around the wearer's temples also vary, which can cause stress concentration due to pressure on the temples when the rigid temples hook or clamp the ears, or cause the frames to wobble due to gaps.

[0006] Furthermore, the wearer's face undergoes dynamic changes. For example, glasses that fit a teenager when purchased may become ill-fitting as the wearer's face grows and develops. In this case, there is no need to replace them with larger frames, but rather to adjust the local contours of the glasses. Another example is short-term facial swelling caused by sleep deprivation or allergies, leading to expansion of the facial soft tissues. This change in facial contour will subside over time.

[0007] As can be seen from the above issues, if the frames and temples can adapt to changes in the wearer's facial contours and undergo a certain degree of structural adjustment, the wearer can adjust the glasses according to their own feelings, which will significantly improve wearing comfort.

[0017] A further feature of this invention is that the thermoplastic rubber material is TR plastic, and the shape memory elastomer material is memory rubber.

[0018] The beneficial effects of this utility model are as follows: First, by incorporating a shape memory elastomer material in the bridge section of the eyeglass frame, its high elasticity allows users to adjust the frame's curvature to fit the contours of their face and eye sockets. Utilizing its shape memory effect, the frame returns to a pre-set curvature, allowing for repeated adjustments. Preferably, this application uses a memory rubber material, and the frame is divided into a central bridge, a left lens ring, and a right lens ring. The central bridge is detachably assembled with the left and right mounting slots using methods such as snap-fit ​​or screw connections. This modular assembly not only facilitates the replacement of parts to meet the user's comfort needs but also allows for combinations of frame shapes, styles, colors, and patterns to satisfy the user's aesthetic preferences.

[0019] Second, the temples are divided into hinge components, bending components, and lug components. The bending components also use shape memory elastomer material, allowing the temples to adapt to the contours around the temples. The temples also incorporate first and second lead screws made of nickel-titanium alloy, such as TR plastic (also known as TR90 / plastic titanium), which utilizes its extremely light weight and excellent toughness to provide core support for the temples.
