Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to a modular eyeglass frame. Background Technology

[0002] Eyeglass frames are an indispensable part of eyeglasses. They consist of a frame with two holes and temples that are hinged to both ends of the frame. Lenses are then snapped into the two holes in the frame to form a complete eyeglass structure.

[0003] However, in actual use, for protective eyewear such as goggles and sunglasses, the frame structure described above cannot effectively block light that travels from the side (i.e., light that passes through the gap between the frame and the user's face). Therefore, existing technologies often add a silicone or rubber strip along the outer edge of the inner side of the frame (i.e., the side facing the user's face when in use) to improve the fit with the user's face when wearing the glasses, thereby effectively blocking light.

[0004] However, due to the material properties of the adhesive strip, after a period of use, this type of elastic material will more or less harden, which will cause the strip to fail to adhere to the user's facial skin. Since the strip is usually fixed to the frame by vulcanization or adhesive, the entire frame needs to be replaced when it needs to be replaced, which is very expensive. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a modular eyeglass frame. The technical problem this invention aims to solve is: how to reduce replacement costs.

[0006] The objective of this utility model can be achieved through the following technical solution: A modular eyeglass frame, comprising a main frame with two holes, characterized in that the modular eyeglass frame further comprises a secondary frame with two holes, wherein the secondary frame and the main frame are engaged and the two holes are positioned opposite each other, the outer edge of the secondary frame facing away from the main frame has a strip made of elastic material, the upper edge of the main frame has an upward flange, the upward flange is arranged along the length direction of the main frame, the lower edge of the main frame has two elongated downward flanges, the two downward flanges correspond one-to-one with the two holes, the upper side of the secondary frame abuts against the inner wall of the upward flange, and the lower side abuts against the two downward flanges.

[0007] Compared to existing technologies, this application differs in that it employs a split frame structure. The main frame serves as the core, with two holes for lens mounting. An additional sub-frame acts as an adapter, detachably connecting to the main frame via a snap-fit ​​connection. During assembly, the upper flange and two lower flanges on the main frame guide the sub-frame during assembly and also assist in its positioning after installation. This ensures a robust connection between the sub-frame and the main frame while maintaining detachability. Furthermore, the sub-frame features a circumferentially elasticated side facing away from the main frame. The adhesive strip, made of a specific material, allows for a snug fit against the user's face through its adaptive elastic deformation, providing ample sun protection and shading. Furthermore, due to the detachable connection between the main frame and sub-frame, if the adhesive strip shows signs of aging after a period of use, the user can remove and replace the sub-frame along with the adhesive strip, while the main frame remains intact. Compared to existing technologies, this avoids many unnecessary disassembly operations, such as removing and installing lenses and temples, making the process more effortless and convenient. Moreover, unlike existing technologies, the entire eyeglass frame does not need to be replaced, effectively reducing replacement costs.

[0008] In the aforementioned modular eyeglass frame, the lower side of the main frame has a connecting portion protruding towards the sub-frame. This connecting portion is plate-shaped and located in the middle of the lower side of the main frame. A positioning groove is formed on the lower side of the upper flange, and a positioning opening is formed on the upper side of the connecting portion, opposite to the positioning groove. The sub-frame has positioning protrusions on both its upper and lower sides; one of these protrusions engages in the positioning groove, and the other engages in the positioning opening. Specifically, during installation, after the upper flange and two lower flanges work together to limit the sub-frame's position, the two positioning protrusions, the positioning groove, and the positioning opening engage one-to-one, thereby fixing the middle of the sub-frame and ensuring a secure connection between the sub-frame and the main frame.

[0009] In the aforementioned combined eyeglass frame, both lower flanges are U-shaped, with the inner end of each flange extending to the lower side of the main frame near the center and the outer end extending to the end of the main frame. Each lower flange has a retaining plate on its inner sidewall at the outer end. The two ends of the sub-frame have corresponding slots for the retaining plates, and the two retaining plates engage with the two slots. Furthermore, based on the above structure, the engagement of the two retaining plates and the two slots achieves secondary locking of the sub-frame. In conjunction with the aforementioned features, two positioning points are located on the upper and lower sides of the middle of the sub-frame, and the other two are located at the ends of the sub-frame. This ensures uniform circumferential force distribution on the sub-frame, guaranteeing a secure installation.

[0010] In the aforementioned modular eyeglass frame, the frame also includes a nose pad. A fixing groove is provided on the side wall of the connecting part opposite the sub-frame. The nose pad includes a frame and an elastic body covering the frame. The frame has a transversely arranged insert plate, which is inserted into and positioned in the fixing groove. This ensures the replaceability of the nose pad and improves the service life of the main frame.

[0011] In the aforementioned modular eyeglass frame, the upper side panel of the insert plate has a fixing protrusion, the positioning port is located above the fixing groove, and the lower end of the positioning port penetrates the upper side wall of the fixing groove. The fixing protrusion is engaged in the positioning port. Specifically, the frame is connected to the fixing groove on the connecting part via the insert plate, and in the final state, the fixing protrusion on the insert plate engages with the positioning port penetrating the upper side wall of the fixing groove, ensuring the connection stability of the insert plate and thus achieving a secure installation of the nose pads.

[0012] In the aforementioned modular eyeglass frame, the insert plate has a U-shaped opening that extends through both sides of the insert plate. An elastic portion is formed within this U-shaped opening on the insert plate, and a fixing protrusion is formed on the upper side of this elastic portion. Based on this structure, the U-shaped opening on the insert plate creates an elastic portion within it, and the fixing protrusion is specifically formed on this elastic portion. During insertion, the fixing protrusion and the groove wall of the fixing groove are interference-fitted, allowing the elastic portion to bend downwards appropriately until the fixing protrusion engages with the lower end of the positioning port. At this point, the elastic portion can elastically return to its original position, thus ensuring the secure connection of the nose pad.

[0013] In the aforementioned modular eyeglass frame, a clearance groove is formed on the lower side wall of the fixing groove. This clearance groove extends along the depth of the fixing groove and reaches the edge of the groove opening. The width of the clearance groove is greater than the width of the elastic part, and the elastic part is located directly above the clearance groove. The clearance groove ensures that the elastic part has adequate space to accommodate downward bending deformation, preventing jamming or interference during insertion.

[0014] In the aforementioned modular eyeglass frame, the outer edge of the upper side wall of the fixing groove has an inclined guide surface. This guide surface ensures that the fixing protrusion is adequately guided when the insert plate is first inserted, thus guaranteeing ease of installation.

[0015] Compared with existing technologies, this modular eyeglass frame has the following advantages:

[0016] The frame is assembled using a modular structure. During installation, the upper and lower flanges are used to limit the position of the sub-frame, and four positioning points on the upper, lower, left, and right sides ensure the connection between the main frame and the sub-frame. An elastic strip is formed on the sub-frame, which not only provides light protection for the user's eyes, but also allows for easy replacement of the sub-frame, effectively reducing replacement costs.

[0027] 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.

[0028] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, this modular eyeglass frame includes a main frame 1 with two holes 11 and a secondary frame 2 with two holes 21. The upper edge of the main frame 1 has an upward-curved edge 12 along its length, specifically protruding towards the back of the main frame 1 (i.e., the side worn by the user). The lower edge of the main frame 1 has two elongated downward-curved edges 13, located below the two holes 11. Each downward-curved edge 13 is curved along its length, so that the outline of each downward-curved edge 13 is similar to the outline of the corresponding hole 11. The inner end of each downward-curved edge 13 extends to the lower side of the main frame 1 near the middle, and the outer end extends to both ends of the main frame 1. The lower side of the main frame 1 has an upward-recessed groove for accommodating the user's nose bridge, the groove corresponding to the center point of the lower side of the frame.

[0029] The back of the sub-frame 2 has a strip 22 made of elastic material along its outer edge, which can be silicone or rubber. Specifically, the strip 22 is C-shaped with the opening facing down to ensure that it makes way for the bridge of the user's nose. During installation, the front of the sub-frame 2 is placed opposite the back of the main frame 1, and inserted with the two holes 11 and 21 aligned one-to-one, so that the upper side wall of the sub-frame 2 abuts against the upper flange 12, and the lower side wall abuts against the two lower flanges 13.

[0030] The main frame 1 has a connecting part 14 protruding towards the sub-frame 2 at the lower middle part of the main frame 1, and the connecting part 14 is specifically plate-shaped. When the above-mentioned insertion action is performed, the lower middle part of the sub-frame 2 can abut against the upper side of the connecting part 14.

[0031] Combination Figure 2 The sub-frame 2 has an integrally formed positioning protrusion 23 with an arc-shaped outer wall on the upper and lower side walls in the middle of the sub-frame 2. The lower side of the upper flange 12 has a positioning groove 121 with an arc-shaped inner wall. The upper side of the connecting part 14 has a positioning opening 141. When the sub-frame 2 and the main frame 1 are connected as described above, one of the positioning protrusions 23 can be engaged in the positioning groove 121 and the other positioning protrusion 23 can be engaged in the positioning opening 141, thereby achieving the locking and positioning of the sub-frame 2 under the premise that the upper flange 12 and the lower flange 13 are cooperated to limit it.

[0032] Combination Figure 3 Each lower flange 13 has a long strip-shaped locking plate 131 protruding towards the end side wall of the sub-frame 2 on its inner wall near the outer end. Corresponding locking grooves 24 are provided on the outer walls at both ends of the sub-frame 2. When the above-mentioned insertion action is performed, while the two positioning protrusions 23 are locked and positioned, the two locking plates 131 can also lock and engage with the corresponding locking grooves 24, thereby achieving full positioning of the upper and lower sides and the left and right ends of the sub-frame 2 and ensuring the firmness of the connection between the main frame 1 and the sub-frame 2.

[0033] Combination Figure 9 This modular eyeglass frame also includes a nose pad 3. Specifically, the nose pad 3 includes a frame 31 and an elastic body 32 that covers and is fixed to the outside of the frame 31. The elastic body 32 can be made of silicone or rubber, and as an alternative, to ensure its structural strength, it can also be made of plastic. A fixing groove 142 is provided on the outer wall of the connecting part 14 facing the sub-frame 2. A horizontally arranged insert plate 311 is provided on the frame 31. A U-shaped opening 3112 is provided on the plate surface of the insert plate 311. The U-shaped opening 3112 passes through the upper and lower sides of the insert plate 311, so that an elastic part 3113 that can be bent and deformed vertically is formed on the insert plate 311 and located in the U-shaped opening 3112. The elastic part 3113 is plate-shaped and has a fixing protrusion 3111 with an arc-shaped outer wall integrally formed on its upper side.

[0034] It should be noted that the positioning port 141 and the fixing groove 142 are arranged vertically. The positioning port 141 specifically penetrates the upper side wall of the fixing groove 142. Furthermore, a clearance groove 1421 is provided on the lower side wall of the fixing groove 142, extending along its depth direction. This clearance groove 1421 extends to the edge of the groove opening of the fixing groove 142. The clearance groove 1421 is specifically located below the elastic part 3113 and its width is greater than the width of the elastic part 3113. Additionally, a downwardly inclined guide surface 1422 is provided on the upper side wall of the fixing groove 142. This allows the user to... Align the insert plate 311 with the fixing groove 142. Under the guidance of the guide surface 1422, insert the insert plate 311 into the fixing groove 142. During the insertion process, the fixing protrusion 3111 can be squeezed by the upper side wall of the fixing groove 142, so that the elastic part 3113 deforms downward into the relief groove 1421 in the U-shaped opening 3112 until the fixing protrusion 3111 moves to align with the lower end of the positioning opening 141. At this time, the squeezing force is lost, and the elastic part 3113 can elastically deform upward and reset, so that the fixing protrusion 3111 is embedded into the lower end of the positioning opening 141, thereby completing the installation of the nose pad 3.
