Description

[Technical Field]

[0001] The present invention relates to overglasses that can be worn over eyeglasses. [Background technology]

[0002] Overglasses are glasses that can be worn over existing eyeglasses. For example, if a person who wears corrective eyeglasses wants to wear sunglasses to protect their eyes from sunlight or strong lighting, or as a fashion statement, they can wear overglasses over their existing eyeglasses without removing them.

[0003] When wearing overglasses over other glasses, it is necessary to prevent the overglasses from slipping off the lower glasses. To achieve this, a rim piece (brim) is provided along the upper edge of the front that protrudes backward from the lens, and the brim hooks onto the front of the lower glasses to prevent the overglasses from slipping off the lower glasses (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-005017 Summary of the Invention [Problem to be solved by the invention]

[0005] If the brim of the overglasses extends too little, depending on the shape of the front of the glasses underneath, the contact area between the brim and the front of the glasses underneath may be too small, causing the brim to not latch properly and causing the overglasses to slip off. In this sense, it is desirable for the brim to extend as much as possible. However, if the brim extends too much, another problem occurs: the tip edge of the brim will hit the face, so the brim cannot extend too much.

[0006] In view of the above problems, the present invention aims to provide overglasses that are less likely to slip down by resolving the above dilemma. [Means for solving the problem]

[0007] According to one aspect of the present invention, there is provided overglasses that can be worn over eyeglasses, the overglasses comprising a pair of left and right lenses, a front that holds the lenses, and a pair of left and right temples, the front having a pair of left and right brow bars that secure the pair of left and right lenses, a bridge that connects the pair of left and right brow bars, a pair of left and right end pieces to which the pair of left and right temples are attached via hinges, and a thin brim that is provided along the upper edges of the brow bars, the bridge, and the end pieces and that protrudes rearward in the front-to-back direction, the amount of protrusion of the brim at the upper edge portion of the bridge being greater than the amount of protrusion at the upper edge portion of the brow bars. [Effects of the Invention]

[0008] According to the present invention, the amount of overhang of the brim at the upper edge of the bridge is greater than the amount of overhang at the upper edge of the brow bar, so that the underside of the brim at least at the upper edge of the bridge comes into contact with the upper edge of the bridge of the lower eyeglasses, allowing the brim to be hooked onto the front of the lower eyeglasses, thereby preventing the overglasses from slipping down. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a plan view of overglasses according to an embodiment of the present invention. [Figure 2] 1 is a front view of overglasses according to an embodiment of the present invention. [Figure 3] 1 is a side view of overglasses according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the inventors provide the accompanying drawings and the following description to enable those skilled in the art to fully understand the present invention, and are not intended to limit the subject matter described in the claims. Furthermore, the dimensions, thicknesses, detailed shapes, etc. of each component depicted in the drawings may differ from the actual ones.

[0011] Fig. 1 is a plan view of overglasses according to one embodiment of the present invention. Fig. 2 is a front view of overglasses according to one embodiment of the present invention. Fig. 3 is a side view of overglasses according to one embodiment of the present invention. In this specification, the sagittal direction, horizontal direction, and vertical direction of the head when the overglasses are worn are defined as the front-to-back direction, left-to-right direction, and up-to-down direction of the overglasses, respectively.

[0012] The overglasses 100 according to this embodiment are glasses, particularly sunglasses, that can be worn over eyeglasses. For example, when a person who wears corrective eyeglasses wants to wear sunglasses to protect their eyes from sunlight or strong lighting, or as a fashion statement, the overglasses 100 can be worn over the eyeglasses they are currently wearing without removing them. Of course, the overglasses 100 can also be worn alone like regular eyeglasses, without being worn over other eyeglasses.

[0013] <Overglasses general configuration> The overglasses 100 according to this embodiment include a pair of left and right lenses 10L, 10R, a front 20 that holds them, and a pair of left and right temples 30L, 30R. The temples 30L, 30R are connected to the front 20 via hinges 50L, 50R provided on end pieces 23L, 23R at both the left and right ends of the front 20, respectively, so that they can be folded toward the front 20.

[0014] The lenses 10L and 10R can be various lenses such as color lenses, polarized lenses, photochromic lenses, mirror lenses, etc. The lenses 10L and 10R may be either prescription lenses or non-prescription lenses.

[0015] <Front configuration example> The front 20 includes a pair of left and right brow bars 21L, 20R, a bridge 22, a pair of left and right end pieces 23L, 23R, a pair of left and right nose pads 24L, 24R, and a brim 25. These members are integrally formed from synthetic resin.

[0016] The brow bar 21L is gently curved so that it bulges slightly forward. The end piece 23L is located at the left end of the brow bar 21L, and the nose pad 24L is located at the lower right end. Slits are formed on the inside of the brow bar 21L, end piece 23L, and nose pad 24L, and the upper edge of the lens 10L and upper portions of the left and right edges fit into the slits to attach the lens 10L to the brow bar 21L.

[0017] The brow bar 21R is gently curved, bulging slightly forward. The end piece 23R is located at the right end of the brow bar 21R, and the nose pad 24R is located at the bottom left end. Slits are formed inside the brow bar 21R, end piece 23R, and nose pad 24R, and the upper edge of the lens 10R and upper portions of the left and right edges fit into these slits to attach the lens 10R to the brow bar 21R.

[0018] Since the overglasses 100 may be worn over other glasses, the lenses 10L and 10R are relatively larger than the lenses of ordinary glasses, and the width of the brow bars 21L and 21R, i.e., the width of the front 20, is also relatively larger than the width of the front of ordinary glasses.

[0019] Bridge 22 is a component that connects the right end of brow bar 21L and the left end of brow bar 21R. More specifically, the front and rear surfaces of bridge 22 are curved with a forward radius. This is because many pairs of eyeglasses have bridges that are curved forward, and when overglasses 100 are placed over such glasses, the front surface of the bridge of the lower pair of glasses does not collide with the rear surface of bridge 22 of overglasses 100.

[0020] The nose pads 24L, 24R are members for supporting the front 20 by sandwiching the bridge of the nose from both sides, and extend below the left and right ends of the bridge 22, respectively.

[0021] The brim 25 is a thin member that is provided along the upper edge of the front 20, specifically along the upper edges of the brow bars 21L, 20R, bridge 22, and end pieces 23L, 23R, and that protrudes rearward in the front-to-back direction. The underside of the brim 25 comes into contact with all or part of the upper edge of the front of the lower glasses, and the brim 25 is hooked onto the front of the lower glasses, preventing the front 20 of the overglasses 100 from slipping down and maintaining the relative positional relationship between the front of the lower glasses and the front 20 of the overglasses 100.

[0022] A large overhang of the brim 25 is preferable to ensure that the front panel 20 is securely fastened to the front panel of the lower eyeglasses, but if it is too large, the leading edge of the brim 25 will come into contact with the brow bone or the area below it. In particular, because the gap between the inner corners of the eyebrows and the front panel 20 is narrowest, the amount of overhang of the brim 25 at the boundary between the brow bars 21L, 20R and the bridge 22, located in this area, cannot be made too large. Therefore, as an example, in the overglasses 100 according to this embodiment, the amount of overhang of the brim 25 from the back surface of the lenses 10L, 10R is approximately 6 mm at the boundary between the brow bars 21L, 20R and the bridge 22, and gradually increases from there toward both ends of the front panel 20, reaching approximately 8 mm at the end pieces 23L, 23R.

[0023] Even if the amount of overhang of the brim 25 gradually increases toward the left and right ends of the front 20 in this manner, depending on the shape and front curvature of the lower eyeglasses, for example, if the curvature of the front surface of the lower eyeglasses is significantly smaller than the curvature of the front 20 of the overglasses 100, there may be almost no contact between the brim 25 and the upper edge of the front of the lower eyeglasses, and the brim 25 may not be properly hooked onto the front of the lower eyeglasses. Therefore, in the overglasses 100, the amount of overhang of the brim 25 at the upper edge of the bridge 22 is made larger than the amount of overhang at the upper edges of the brow bars 21L, 20R. Specifically, the brim 25 at the upper edge of the bridge 22 overhangs rearward in the front-to-rear direction in a curved shape. For example, the brim 25 overhangs the upper edge of the bridge 22 by a maximum of 4 to 5 mm from the left and right ends of the bridge 22.

[0024] The overhanging portion of the brim 25 at the upper edge of the bridge 22 is located at the bridge of the nose, slightly recessed from the forehead, on a human face, so even if the brim 25 is curved, its leading edge will not come into contact with the face. By making the brim 25 overhang the upper edge of the bridge 22 by a relatively large amount, the underside of the brim 25 at the upper edge of the bridge 22 comes into contact with the upper edge of the bridge of the lower eyeglasses, ensuring that the brim 25 is securely fastened to the front of the lower eyeglasses, regardless of the front shape or curvature of the lower eyeglasses. This prevents the front 20 of the overglasses 100 from slipping down and maintains the relative positional relationship between the front of the lower eyeglasses and the front 20 of the overglasses 100.

[0025] <<Variations>> The frame of the illustrated overglasses 100 is a half-rim type, but may be a full-rim type.

[0026] The brow bars 21L, 20R, bridge 22, end pieces 23L, 23R, nose pads 24L, 24R, and brim 25 may not be integrally formed, but may be all or some of them may be separate components. Furthermore, these components may be made of metal.

[0027] The nose pads 24L and 24R may be omitted. If the nose pads 24L and 24R are omitted, the lenses 10L and 10R may be joined together to form a one-piece lens.
