Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to eyeglasses with adjustable temple spacing. Background Technology

[0002] Eyeglasses are common optical devices in modern life. Structurally, existing eyeglasses generally consist of a frame and two temples hinged to the frame, such as the eyeglass hinge assembly disclosed in Chinese Patent (Application Publication No.: CN103238100A), which connects the temples to the eyeglass frame. The eyeglass frame can be composed of one or more frame components. The components of the eyeglasses (including the temples and the frame) are replaceable, allowing for quick and easy changes to the color, shape, and style of the glasses. The temples are securely connected to the eyeglass frame, but their connection method allows for easy removal and replacement. The temples need to deform, bend, or move beyond their normal orientation to allow for easy disconnection. In a preferred embodiment, the temple hinge assembly includes a hook-like element and a pivot, wherein the pivot includes a groove or cut-off portion positioned such that the hook-like element can only engage / disengage when the temple is deformed or moves beyond its normal position.

[0003] According to paragraphs 0057-0058 of the specification in the prior art document, the eyeglass assembly includes a frame and two temples, which are pivotally connected to the frame via a hinge assembly or connecting device. However, certain drawbacks exist in actual use. Specifically, the lifespan of a pair of eyeglasses can be as long as 3-5 years. During this time range, the wearer's weight is not constant. In particular, when the wearer gains weight, it is highly likely to cause a change in the width of their face (especially when the user's face width increases). The distance between the two temples, which was originally intended to fit the user's face shape, may cause the temples to be squeezed outwards due to the increased width of the user's face. Over time, this can not only cause the overall glasses to deform, but also cause discomfort to the user's face due to prolonged pressure from the temples, and may also leave indentations that cannot disappear quickly, resulting in poor fit. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an adjustable temple spacing for eyeglasses. The technical problem this invention aims to solve is: how to improve the fit of the eyeglasses.

[0005] The objective of this utility model can be achieved through the following technical solution: a pair of glasses with adjustable temple spacing, comprising a frame and two temples, characterized in that, both ends of the frame are fixed with elongated and horizontally arranged fixing blocks, and each temple is hinged with a slider at its front end. The slider is slidably connected to the fixing blocks along the length direction of the frame, so that the two temples can slide inward or outward along the length direction of the frame. Furthermore, each fixing block is screwed with a fastener, and the slider is pressed and positioned on the fixing block by the fastener.

[0006] This application uses a frame to mount a fixing block and employs a slider and temples for hinge connection. Based on this structure, by sliding the slider and temples together, and utilizing the sliding engagement between the slider and the fixing block, the two temples can slide inward or outward relative to each other, thereby adjusting the distance between the two temples. After the sliding adjustment is completed, fasteners press the slider onto the fixing block, thus achieving effective positioning of the two temples and ensuring that the distance between the two temples is maintained. Compared with the prior art, this application adopts the above structure, allowing the wearer to adaptively adjust the distance between the two temples according to their actual facial features (i.e., face width), preventing the two temples from bending outward due to pressure from the wearer's face. Secondly, it can also prevent the temples from pressing on the wearer's cheeks, causing pressure marks and pain, thus ensuring the overall lifespan of the glasses while effectively ensuring the fit of the glasses.

[0007] In the aforementioned adjustable temple spacing eyeglasses, the fixing block has a T-shaped cross-section, and the slider is a long strip with a T-shaped groove on one side. The groove extends through both ends of the slider, allowing it to slide smoothly over the fixing block. Specifically, the T-shaped fixing block and the groove on the slider allow the slider to slide along the length of the fixing block, thereby adjusting the distance between the two temples.

[0008] In the aforementioned adjustable temple spacing eyeglasses, a strip-shaped hole is provided on the other side of the slider. This hole extends along the length of the slider and through to the bottom wall of the groove. The fastener is a handle screw; one end of the fastener passes through the strip-shaped hole and is screwed to the fixing block, while the other end is pressed against the outer wall of the slider. With this design, when the fastener is loose, the slider can drive the temple to slide along the length of the fixing block. The sliding distance of the slider is limited by the cooperation of the fastener and the strip-shaped hole. When the fastener is tightened, it presses against the slider, thereby positioning the slider on the fixing block and thus positioning the temple.

[0009] In the aforementioned adjustable temple spacing eyeglasses, the fixing block has a notch in the middle of the side facing away from the bottom wall of the sliding groove. The front end of the fastener extends into the notch, and a clamp is provided within the notch, which engages and fixes the front end of the fastener. This design ensures the positioning of the fastener and prevents it from being excessively twisted outwards and falling off.

[0010] In the aforementioned adjustable temple spacing eyeglasses, the length of the slotted hole is greater than or equal to one-third of the slider length, and the slotted hole is located near one end of the slider. The slider has a hinge at the other end of its side with the slotted hole, and the temple is hinged to the hinge. This design makes efficient use of the space on the side of the slider, ensuring a reliable connection between the slider and the temple while guaranteeing that the length of the slotted hole meets practical requirements and ensuring sufficient temple sliding range.

[0011] In the aforementioned adjustable temple spacing eyeglasses, a stepped hole is formed on the side wall of the fixing block facing the bottom wall of the sliding groove, and the stepped hole extends through the other side wall of the fixing block. A screw with one end screwed to the frame is installed in the stepped hole, and the other end of the screw is embedded in the stepped hole and pressed against the stepped surface of the stepped hole. This design ensures a stable connection between the fixing block and the frame, while allowing for individual disassembly during subsequent maintenance and repair, effectively reducing maintenance costs. Furthermore, the stepped hole effectively accommodates the screw used to fasten the fixing block, preventing it from protruding from the surface of the fixing block and interfering with the bottom wall of the sliding groove of the slider.

[0012] In the aforementioned adjustable temple spacing eyeglasses, the two ends of the frame are provided with U-shaped receiving grooves. The fixing block is fixed to the bottom wall of the receiving groove, and the slider is slidably connected within the receiving groove, with its two side surfaces fitting against the groove walls. This effectively accommodates the fixing block and the slider, ensuring the overall consistency of the eyeglass structure. Furthermore, the groove walls can also cooperate with the side walls of the slider, thus ensuring guidance for the slider's sliding direction.

[0013] Compared with existing technologies, these adjustable temple spacing glasses have the following advantages:

[0014] This application installs fixing blocks at both ends of the frame and hinges sliders to the front ends of each temple. The sliders are slidably connected to the fixing blocks. The sliding of the sliders allows for adaptive adjustment of the distance between the two temples. After the adjustment is completed, the sliders are locked with fasteners to ensure the structural stability of the glasses after the above adjustment. Attached Figure Description

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1-3 As shown, this eyeglass with adjustable temple spacing includes a frame 1 and two temples 2, combined with... Figure 7 A U-shaped receiving groove 12 is provided at both ends of the side wall of the frame 1. Each receiving groove 12 is provided through the end of the frame 1. A long strip-shaped fixing block 11 is screwed and locked in the receiving groove 12 by screws 1121. A long strip-shaped slider 21 is hinged to the front end of each temple 2.

[0027] Combination Figure 4 and Figure 9Each fixing block 11 has a T-shaped cross-section. Two stepped holes 112 are opened on the side facing away from the wall of the receiving groove 12. The two stepped holes 112 are arranged at intervals along the length of the fixing block 11, and each stepped hole 112 penetrates the other side of the fixing block 11. Each stepped hole 112 is provided with a screw 1121. One end of the screw 1121 is screwed to the bottom wall of the receiving groove 12, and the other end of the screw 1121 is received in the stepped hole 112 and pressed against the stepped surface of the stepped hole 112.

[0028] Combination Figure 8 Each slider 21 has a T-shaped groove 211 on one side. The groove 211 is arranged horizontally and passes through both ends of the slider 21. The slider 21 is inserted into the receiving groove 12 and is slidably sleeved on the outside of the fixing block 11 through the groove 211. The two side walls of the slider 21 are in contact with the inner side wall of the receiving groove 12, so that the slider 21 can slide along the length direction of the fixing block 11. Secondly, a hinge part 213 is integrally formed at one end of the other side of the slider 21. The temple 2 is specifically hinged to the hinge part 213 through the hinge. A strip hole 212 is also provided on this side of the slider 21. The strip hole 212 is opened along the length direction of the slider 21 and is located close to the other end of the slider 21.

[0029] Combination Figure 5 and Figure 6 Each fixing block 11 is screwed with a fastener 111. Specifically, the fastener 111 is a handle screw. A threaded hole is opened on the side of the fixing block 11 facing the bottom wall of the slide groove 211, and a notch 113 is opened on the side wall of the fixing block 11 facing away from the bottom wall of the slide groove 211. One end of the fastener 111 passes through the strip hole 212 and is screwed to the threaded hole. The front end of the fastener 111 extends into the notch 113 and is engaged with the front end of the fastener 111 by a clamp 1131, so that the fastener 111 is limited to the fixing block 11 along the length of the temple. The other end of the fastener 111 abuts against the outer wall of the slider 21. The slider 21 is clamped by the threaded engagement between the fastener 111 and the fixing block 11.

[0030] It is worth mentioning that, as an alternative solution, the slide groove 211 can also be opened on the fixed block 11, and the cross-sectional shape of the slider 21 can be set to T-shape. For the positioning of the slider 21, the original strip hole 212 can be changed to a circular hole. At the same time, multiple threaded holes are opened on the side wall of the fixed block 11. Several threaded holes are spaced apart along the length of the fixed block 11. After sliding the slider 21 as required, the circular hole and any one of the threaded holes can be aligned and the fastener 111 can be tightened.

[0031] Operating principle: Before wearing the glasses, the wearer can first unscrew the fasteners 111 outwards, and pull or push the temples 2 outwards or inwards along the length of the frame 1 according to the width of their head. The slider 21 slides a certain distance relative to the fixed block 11, so that the distance between the two temples 2 is adapted to the width of the wearer's head. Then, the fasteners 111 are screwed inwards to keep the slider 21 in place, thereby ensuring that the temples 2 and the frame 1 are kept in place.
