Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses technology, and in particular to an adjustable lens frame for trial wear. Background Technology
[0002] In the ophthalmological optometry and glasses fitting process, after the refraction is completed and before the formal glasses fitting, a trial frame is used to allow the patient to try on the glasses. This is a crucial step to ensure the accuracy of the glasses fitting and the comfort of wearing them. During the trial, it is necessary to ensure that the patient's eyes can simultaneously see through the optical center of the lenses on the trial frame, so as to achieve clear vision and avoid visual distortion or aberration. Only after the patient confirms that there is no discomfort during the trial can the subsequent glasses fitting work be carried out based on the trial parameters. Therefore, the trial frame has become an important tool connecting the refraction and glasses fitting.
[0003] While existing trial frames can adjust the interpupillary distance to suit different patients and meet their horizontal needs, they are significantly lacking in vertical adjustment, failing to adjust the height of the lens rims. Furthermore, some patients have physiological characteristics such as unequal ear heights, which can cause their eyes to not align with the optical center of the lenses simultaneously when using existing trial frames. This often results in one eye seeing through the center of the lens while the other sees through a point slightly above or below the center, directly affecting the visual experience during the trial and potentially interfering with the accuracy of subsequent prescription parameters. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable lens frame for trial wear, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable lens frame for trial wear, comprising a frame, connecting arms, an adjustment module, and lenses. The frame consists of two sets in an inverted U-shape. The connecting arms are integrally formed and connected to adjacent sides of the two sets of frames. The adjustment module is located between the two sets of connecting arms, with the ends of the two connecting arms extending into the adjustment module away from their connected frames. The adjustment module is connected to the two sets of connecting arms and is used to adjust the horizontal relative position of the two sets of connecting arms. By adjusting the horizontal relative position of the two sets of connecting arms, the lens height can be adjusted to meet the trial wear needs of patients with uneven ear heights, ensuring that both eyes are simultaneously aligned with the optical center of the lenses.
[0006] Preferably, the adjustment module includes a U-shaped block, which is a cylindrical hollow structure with openings on both sides. The inner wall of the U-shaped block is integrally formed with a sliding groove distributed along the Y-axis. The ends of the two sets of connecting arms extend into the U-shaped block and are slidably connected to the U-shaped block through the sliding grooves inside the U-shaped block. The sliding grooves can provide guidance for the sliding of the connecting arms, ensuring the stability of the horizontal relative position adjustment process of the connecting arms and avoiding the adjustment offset from affecting the height adaptation effect of the lens ring.
[0007] Preferably, the adjustment module further includes bolts and nuts. The top surface of the U-shaped block is integrally formed with two sets of threaded holes penetrating through it. The outer wall of the connecting arm extending into the U-shaped block is also integrally formed with a through threaded hole and is coaxial with the threaded hole on the U-shaped block. Bolts are threaded into the two sets of threaded holes on the U-shaped block. The bottom end of the bolt extends into the U-shaped block and is rotatably connected to the bottom surface of the U-shaped block. A nut is integrally formed at the top of the bolt outside the U-shaped block. By turning the nut, the bolt can be rotated, which can conveniently drive the two sets of connecting arms to adjust their horizontal relative positions along the slide groove. The operation is simple and can accurately control the height adjustment range of the lens ring, further ensuring the accuracy of the eyes aligning with the optical center of the lens.
[0008] Preferably, both ends of the frame are integrally formed with extension arms that clamp the two sides of the lens and extend towards the curved corner of the lens. The end of the extension arm away from the frame is integrally formed with a lever arm that does not contact the lens. The lever arm can be easily operated by the operator or patient, providing a convenient operating point for lens installation and removal without the need for additional tools.
[0009] Preferably, the extension arm is connected to a surround piece that bends and extends toward the lens side. The surround piece is a curved strip structure with an L-shaped cross-section. The L-shaped curved surround piece can form a stable surround for the lens. At the same time, it can deform when the lever arm is turned, so as to realize the quick installation and removal of the lens. It is suitable for the need to frequently change trial lenses with different parameters during the optometry process. The inner side of the frame and the surround piece are integrally formed with multiple sets of slots distributed along their inner edges. The slots are used to place the lens.
[0010] Preferably, the frame is connected to a frame bend on the side, and a hinge arm is hinged to the end of the frame bend away from the frame. A temple is connected to the end of the hinge arm away from the frame bend. A nose pad is connected to the frame between the two sets of frames. The combination of the frame bend, hinge arm and temple can adapt to different head shapes and ear positions. The nose pad can improve wearing stability and comfort, and further help ensure the alignment of the optical center of the lens with the eyes during the trial wearing process.
[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This adjustable lens frame for trial fitting, by disconnecting the connecting arm in the middle of the existing frame and sliding the two sets of connecting arms into the same U-shaped block, and with the threaded connection structure of the bolts and the two sets of connecting arms, can flexibly adjust the horizontal relative position of the two sets of connecting arms by turning the bolts, thereby achieving precise adjustment of the lens height. This design can specifically solve the defect of existing trial frames that cannot adapt to patients with unequal ear heights, so that these patients can adjust the lens height during trial fitting to ensure that both eyes can simultaneously align with the optical center of the trial lens, effectively avoiding the situation where one eye sees through the lens center too high or too low, significantly improving the trial fitting experience and ensuring the accuracy of the prescription parameters.
[0012] (2) This adjustable lens frame for trial fittings features a convenient lens installation and removal structure created by disconnecting the bottom of the frame and using an elastic material edge to surround the lens. During use, simply moving the elastic material edge allows for quick lens installation or removal, making it simpler and more efficient than traditional trial fitting frames. This significantly reduces the time spent changing trial lenses during the trial fitting process, improving the overall efficiency of the optometry and lens fitting process.

[0015] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] Please see Figure 1-7 This utility model provides a technical solution: an adjustable lens frame for trial wear, including a frame 1, connecting arms 5, an adjustment module 6, and lenses 7. The frame 1 consists of two sets in an inverted U-shape. The connecting arms 5 are integrally formed and connected to adjacent sides of the two sets of frame 1. The adjustment module 6 is located between the two sets of connecting arms 5, with the ends of the two sets of connecting arms 5 extending into the adjustment module 6 away from their connected frame 1. The adjustment module 6 is connected to the two sets of connecting arms 5 and is used to adjust the horizontal relative position of the two sets of connecting arms 5. By adjusting the horizontal relative position of the two sets of connecting arms 5 through the adjustment module 6, the height of the frame 1 can be adjusted to meet the trial wear needs of patients with unequal ear heights, ensuring that the patient's eyes can simultaneously align with the optical center of the lenses 7. The adjustment module 6 includes a U-shaped block 61, which is a cylindrical hollow structure with openings on both sides. The inner wall of the U-shaped block 61 is integrally formed with grooves distributed along the Y-axis. The ends of the two sets of connecting arms 5 extend into the U-shaped block 61 and pass through the grooves within the U-shaped block 61. The connecting arm 5 is slidably connected to the U-shaped block 61. The groove on the inner wall of the U-shaped block 61 provides stable guidance for the sliding of the connecting arm 5, preventing the connecting arm 5 from shifting during adjustment, thereby ensuring the accuracy of the height matching of the frame 1. The adjustment module 6 also includes bolts 62 and nuts 63. The top surface of the U-shaped block 61 is integrally formed with two sets of threaded holes that penetrate through it. The outer wall of the connecting arm 5, where it extends into the U-shaped block 61, is also integrally formed with threaded holes that are coaxial with the threaded holes on the U-shaped block 61. Both sets of screw holes are threaded with bolts 62. The bottom end of the bolt 62 extends into the U-shaped block 61 and is rotatably connected to the bottom surface of the U-shaped block 61. The top of the bolt 62 is integrally formed with a nut 63 on the outside of the U-shaped block 61. The operator can easily drive the two sets of connecting arms 5 to adjust their horizontal relative positions along the slide by turning the nut 63 to rotate the bolt 62. This not only makes the operation simple, but also allows for precise control of the height adjustment range of the frame 1, further ensuring the alignment effect between the eyes and the optical center of the lens 7.
[0017] The frame 1 has integrally formed extension arms 9 at both ends, which clamp the two sides of the lens 7 and extend towards the curved corners of the lens 7. At the end of the extension arm 9 furthest from the frame 1, there is an integrally formed lever arm 10 that does not contact the lens 7. The lever arm 10 at the end of the extension arm 9 allows the operator or patient to easily apply force to move it, providing a convenient operating point for the installation and removal of the lens 7 without the need for additional tools. An enclosing piece 11, which bends and extends towards the lens 7, is connected to the edge of the extension arm 9. The enclosing piece 11 is a curved strip structure with an L-shaped cross-section. The L-shaped enclosing piece 11 can stably enclose the lens 7. Under the cooperation of the lever arm 10, the enclosing piece 11 can undergo appropriate deformation, thereby achieving the desired lens 7 installation and removal. The quick assembly and disassembly of lens 7 can accommodate the need for frequent changes of trial lenses 7 with different parameters during the optometry process. Multiple sets of slots 12 distributed along their inner edges are integrally formed on the inner sides of both the frame 1 and the bezel 11. The slots 12 are used to place the lens 7. A frame bend 2 is connected to the side of the frame 1. A hinge arm 3 is hinged to the end of the frame bend 2 away from the frame 1. A temple 4 is connected to the end of the hinge arm 3 away from the frame bend 2. A nose pad 8 is connected to the frame 1 between the two sets of frames 1. The combination of the frame bend 2, hinge arm 3 and temple 4 can accommodate different head shapes and ear positions of patients. The nose pad 8 can improve the stability and comfort of the patient when wearing the lens. The two together help to ensure the alignment of the optical center of the lens 7 with the eyes during the trial fitting process.
[0018] Working principle: When adjustment is needed, use a screwdriver or other tools to turn the nut 63, and the bolt 62 will rotate accordingly. The connecting arm 5 moves under the drive of the bolt 62 and the guide of the sliding groove of the retaining block 61, thereby achieving the effect of adjusting the horizontal height of the two sets of connecting arms 5. Both sets of hinge arms 3 and temples 4 are adjusted. When removing or installing the lens 7, turn the lever arm 10, and the extension arm 9 will bend accordingly, so that the lens 7 can be removed from the frame 1.
[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
