Description

Eyeglass structure

This work relates to a pair of glasses, particularly one with a protective frame that can be detachably attached to the back of the glasses.

Glasses typically have a single function, including correcting myopia, hyperopia, astigmatism, presbyopia, or strabismus. As a result, consumers today often own multiple pairs of glasses with different functions for easy replacement. This situation, however, creates a financial burden for consumers and also creates issues with glasses storage.

Other functional eyewear, including goggles, sunglasses, and sports glasses, offers various types of eye protection, allowing consumers to choose the right one for each occasion. However, existing protective glasses designed to protect against wind, dust, or foreign body spray are mostly single-function, making them difficult to use for those who already wear corrective eyeglasses. While these glasses can be directly stacked on top of corrective eyeglasses, they can also interfere with the frame and temples of the corrective eyeglasses, creating a gap between the side panels and the face, resulting in inadequate eye protection.

In view of the shortcomings and deficiencies of existing technologies, this invention provides a spectacle structure with a protective frame that can be detachably attached to the back of the glasses.

To achieve the above-mentioned objectives, the technical means employed in this creation is a spectacles structure, which mainly includes:

A spectacle frame unit comprises a spectacle frame, wherein a pivot seat is provided on each side of the spectacle frame, and a hook groove is provided on the inner side of each pivot seat; and

A liner rests against the inner side of the frame. A hook portion is provided on each side of the liner, and each hook portion is removably inserted into a corresponding hook groove. The shape of the hook groove matches the shape of the hook portion. A snap-fit portion is provided at the top of the liner, and the snap-fit portion has a downwardly opening snap-fit groove. The top of the eyeglass frame unit is inserted into the snap-fit groove, and a partial frame section at the bottom of the liner rests against the bottom edge of the frame. An elastic pad is provided along the inner edge of the liner to rest against the wearer's face.

In this way, the frame is restricted in its left, right, up, or down position relative to the frame by the abutment of the hook portions, the snap-fit portion, and the frame abutment portion, allowing the frame to be fixed to or detached from the rear side of the frame depending on the usage scenario.

The following describes the implementation of this invention through specific embodiments. Those familiar with this technology can easily understand the other advantages and functions of this invention from the content disclosed in this specification.

Please refer to Figures 1 to 3, which are a preferred embodiment of the eyeglass structure of this invention, which mainly includes: a frame unit (1), a lining frame (2) and a wearing unit (3), wherein the frame unit (1) includes a frame (11) and a lens (12), the lining frame (2) is arranged on the inner side of the frame (11), and the wearing unit (3) is pivoted on both sides of the frame (11). This invention defines the side of the frame (11) facing the wearer's face when worn as the inner side.

The inner edge of the frame (11) is provided with a lens groove (111), and the lens (12) is embedded in the lens groove (111). A pivot seat (112) is extended backward on both sides of the frame (11). The inner side of each pivot seat (112) is provided with a hook groove (113), and a pivot groove (114) is further provided to connect each hook groove (113). Each pivot groove (114) passes through the inner side and rear end of the pivot seat (112). This invention does not limit the form of the lens (12). It can be a single-sided lens or a double-sided lens embedded in the lens groove (111). The figure uses a single-sided lens as an example for illustration.

5 to 7, the lining frame (2) is provided with a hook portion (21) on both sides, and a buckle portion (22) is provided on the top of the lining frame (2) toward the outside. The buckle portion (22) has a buckle groove (23) with an opening (231) facing downward. The two ends of the buckle groove (23) are open. The inner side of the lining frame (2) is along the frame. An elastic pad (24) is provided. The invention does not limit the material of the elastic pad (24), such as silicone, rubber, foam, etc., which can be elastically deformed along the facial contour and attached to the wearer's face after the frame (11) is worn. The elastic pad (24) can be the same or different from the material of the frame (2). In this embodiment, two spaced arc convex portions (241) are provided on both sides of the elastic pad (24) corresponding to each of the pivot seats (112), but the invention is not limited to this.

The wearing unit (3) has two wearing parts (31) that are symmetrical to each other and are respectively pivoted on each pivot seat (112) and can be pivoted between an unfolded position and a folded position relative to the pivot seat (112).

As described above, the outer side of the lining frame (2) is against the inner side of the frame (11), and each of the hook portions (21) is detachably embedded in each of the hook grooves (113) due to the elasticity of its material, thereby limiting the left and right positions of the lining frame (2) relative to the frame (11). As shown in FIG7 , the lining frame (2) detachably fastens the buckling portion (22) to the top of the frame unit (1) due to the elasticity of its material, and the frame section (P) in the middle of the bottom of the lining frame (2) is against the bottom edge of the frame (11), thereby limiting the upper and lower positions of the lining frame (2) relative to the frame (11), thereby fixing the lining frame (2) to the inner side of the frame (11).

Please refer to Figures 2 and 4. To enhance the stability of the combination of the frame (11) and the backing frame (2), the backing frame (2) is provided with a frame groove (25) on the outer side. The frame (11) is accommodated in the frame groove (25). A positioning groove (115) is provided on both sides of the inner side of the frame (11) corresponding to the nose bridge. The backing frame (2) is provided with two positioning protrusions (26) on the outer side of the frame groove (25) that match the shape of the positioning grooves (115). The portion (26) is embedded in each of the positioning grooves (115). Thus, in addition to being coupled to the lens frame (11) by the hook portion (21) and the buckle portion (22), the lens frame groove (25) is further provided to surround the outer edge of the lens frame (11). Furthermore, the positioning protrusions (26) are further embedded in each of the positioning grooves (115) of the lens frame (11) at the middle of the lens frame (2), so that the coupling between the lens frame (11) and the lens frame (2) is more secure.

1, 2 and 7 to 9, in this embodiment, a notch (116) is provided in the middle section of the top of the frame (11), and each of the lens grooves (111) adjacent to the notch (116) of the frame (11) is provided with an engaging portion (117), so that the top of the frame (11) is formed into an open shape by the notch (116). The top edge of the lens (12) is provided with two spaced-apart engaging grooves (121), and each engaging portion (117) of the lens frame (11) is respectively embedded in each engaging groove (121), and the lens (12) between the two engaging grooves (121) is accommodated in the cutout (116) of the lens frame (11), and the lens (12) located between the two engaging grooves (121) is embedded in the buckling groove (23), and the lens (12) can be operably detached from the lens groove (111) through the cutout (116).

Furthermore, referring to FIG5 and FIG6, in this embodiment, each hook portion (21) has a hook rod (211) extending from the lining frame (2) and a hook tip (212) extending from the end of the hook rod (211) toward the lens (12). The lining frame (2), the hook rod (211) and the hook tip (212) together define a hook opening (213), wherein the shape of each hook groove (113) matches the shape of each hook portion (21), so that each hook tip (212) is embedded in each hook groove (113), and the groove wall on one side of each hook groove (113) is embedded in each hook opening (213), thereby preventing each hook portion (21) from easily detaching from each hook groove (113).

Please refer to Figures 1 to 3, 5 and 6. To enhance the diversity of this invention, each wearing piece (31) includes a body (311) and a buckle (312). In this embodiment, the body (311) is in the shape of a long rod, one end of which can be worn on the wearer's ear. The front end of the body (311) is recessed with a buckle slot (3111), and the inner side of the body (311) is provided with a pressing hole (3112) connected to the buckle slot (3111). The front end of the buckle (312) forms a pivoting portion (3121) pivoted on the pivoting seat (112). A spring (3122) extends from the rear end of the pivoting portion (3121), and a pressing portion (3123) is protruded from the end of the spring (3122). The pressing portion (3123) is embedded in the pressing hole (3112), and a retreat distance (H1) is formed between the outer side of the spring (3122) and the wall surface of the pressing hole (3112).

As described above, when the pressing portion (3123) is pressed to cause the elastic sheet (3122) to elastically deform and disengage from the pressing hole (3112) and retreat into the buckle slot (3111) (in the direction of the solid arrow in Figure 6), the wearer can operate the body (311) to apply force to the rear end (in the direction of the hollow arrow in Figure 6) to disengage the body (311) from the buckle (312). In this way, the wearer can replace different types of wearing parts (31) according to the usage scenario.

Please refer to Figure 10, which shows another embodiment of each main body (311) according to the above structural variation. Therefore, the structural similarities will not be described in detail. The following only describes the structural differences. In this embodiment, the rear section of each main body (311) has a through-hole (3113). The through-hole (3113) can be connected to the two ends of an elastic rope (4). When each main body (311) is connected to each buckle (312), the elastic rope (4) can be used to fix the eyeglass frame unit (1) to the wearer's head.

Furthermore, in order to allow each of the wearing parts (31) of the present invention to pivot smoothly to the folded position, as shown in FIG11 , a notch (242) can be provided on both sides of the elastic pad (24) corresponding to each of the pivot seats (112), thereby allowing each of the wearing parts (31) to avoid interference with the elastic pad (24) when in the folded position.

Here, this invention can be used in various ways according to different usage scenarios. As shown in Figures 1 to 7 and 11, when the usage scenario requires protection from wind, dust or foreign objects, the hook portion (21), the buckle portion (22) and the bottom of the lining (2) are pressed against the bottom of the frame (11), and the lining (2) is fixed to the inner side of the frame (11), so that the elastic pad (24) is pressed against the face and frames the wearer's eyes, thereby achieving a protective effect.

Alternatively, as shown in Figures 8 and 9, after the lining frame (2) is detached from the lens frame (11), the spectacles can be used as daily wear. By applying force to the lens frame (11) at both ends adjacent to the cutout (116), the lens frame (11) can be slightly deformed according to the elasticity of its material, so that the fitting portion (117) is disengaged from the fitting groove (121), and the lens (12) can be taken out and replaced with prescription lenses, sun lenses, goggles, or photochromic lenses.

In addition, as shown in FIG10 , each of the wearing parts (31) of the invention can be replaced by operating each of the buckles (312) to separate each of the main bodies (311) from each of the buckles (312), so that the invention can be replaced into different usage modes according to the usage scenario, thereby enhancing the functionality and variability of the invention.
