Description

Technical Field

[0001] This invention relates to an eyeglass-shaped frame that supports functional accessories, which include not only eyeglass lenses and face shields, but also wearable devices such as lights, cameras, and small displays. Background Technology

[0002] The eyeglass-shaped frame is stably supported at four points: the left and right nose pads, mounted on the frame, are secured to the sides of the nose bridge, and the left and right temples, curved at the front, are hooked above the ears. Furthermore, even when the nose pads are not needed, such as when the nose pads are pressed against the temples, the frame is still stably supported at four points by the nose pads and temples. The temples, made of flexible materials such as β-type titanium alloy and stainless steel, utilize their elasticity to hold the wearer's head from both sides, ensuring that the frame will not easily deviate from the wearer's face even when the wearer lowers their head, moves their head, or exercises.

[0003] However, there are many different cross-sectional shapes for the temples of eyeglasses. Rectangular temples can concentrate elasticity in one direction, thus clamping the wearer's head firmly from both sides, making it difficult for the frame to deviate from the wearer's face. However, when putting on or taking off eyeglasses, the curved temples must slide along the wearer's ears while simultaneously pushing them up, placing a significant load on the ears. This not only causes discomfort and pain but also applies considerable torsional force to the frame, leading to deformation after repeated removal and replacement, and the inability to achieve stable support at four points. Furthermore, when wearing eyeglasses, if impacts or other external forces are applied to the frame due to movement, the temples may be pressed against the ear, potentially causing ear pain, or repeated impacts may cause friction between the temples and the ear, injuring the ear.

[0004] The round cross-section of the temples allows for elastic deformation in all directions. Therefore, when putting on or taking off eyeglass frames, the advantage is that the temples can bend, making them easy to put on and take off, and reducing the torsional force applied to the frame. The disadvantage is that the elasticity is dispersed, making it impossible to hold the wearer's head firmly from both sides, and the frame is prone to deviating from the wearer's face.

[0005] The temples of the eyeglasses frame described in Patent Document 1 are configured to bend or push outwards at an angle to the upper side. This not only eliminates the aforementioned disadvantages of temples with circular cross-sections, namely the disadvantage that temples can elastically deform in all directions, causing eyeglasses frames to be prone to misalignment, but also ensures that even if the cross-section of the temples is made into a vertically elongated rectangle, the temples will bend upwards at an angle when the glasses are removed, making it easier to remove the glasses (see paragraphs 0006, 0007, and 0019 of the specification).

[0007] [Patent Documents]

[0008] Patent Document 1: Japanese Patent Application Publication No. 2002-182165 (see paragraphs 0006, 0007 and 0019 of the specification) Summary of the Invention

[0009] However, in the eyeglasses-shaped frame described in Patent Document 1, the force exerted on the wearer's head from both sides is distributed diagonally upwards, making the frame prone to deviating from the wearer's face. Furthermore, the elastic force acts only in a diagonally upward direction, so the temples cannot flexibly deform to conform to the complex shape of the head, and the torsional force applied to the frame remains relatively large, which is insufficient to solve the problem of repeated removal and wearing causing deformation of the eyeglasses-shaped frame.

[0010] In view of the above problems, the present invention aims to provide an eyeglass frame that combines the advantages of rectangular and circular temples, which can solve the problems that the eyeglass frame described in Patent Document 1 cannot solve, and reduce the load on the ears when the eyeglass frame is put on or taken off or when it is subjected to impact.

[0011] To address the aforementioned problems, as described in claim 1, the eyeglass frame of the present invention includes a frame and temples, the temples being disposed at both ends of the frame and having end caps. The eyeglass frame is configured as follows: it includes a first elastic portion disposed on one side of the frame, and a second elastic portion disposed between the first elastic portion and the temples; the first elastic portion allows elastic deformation in a first direction while restricting elastic deformation in directions other than the first direction; the second elastic portion allows elastic deformation in a second direction intersecting the first direction while restricting elastic deformation in directions other than the second direction; the first direction is for clamping the wearer of the eyeglass frame. The second direction is the vertical direction orthogonal to the left-right direction of the head; when wearing the eyeglasses frame, the second elastic part will not elastically deform in the vertical direction when no force is applied in the vertical direction; when putting on or taking off the eyeglasses frame, the first elastic part and the second elastic part elastically deform along the head by combining their respective bidirectional flexion; the elastic force of the first elastic part and the second elastic part, by combining elastic deformation in two different directions, not only suppresses the deformation of the eyeglasses frame caused by the force applied to the eyeglasses frame when putting on or taking off the eyeglasses frame, but also reduces the load and pain on the wearer's ears.

[0012] As described in claim 2, the first elastic portion can be allowed to undergo elastic deformation in the vertical direction, and the second elastic portion can be allowed to undergo elastic deformation in the horizontal direction.

[0013] The first elastic part can also be provided at the head of the frame, etc., but as described in claim 3, both the first elastic part and the second elastic part can be provided on the temple.

[0014] With this configuration, for example, the first elastic part can concentrate the elastic force in one direction, clamping the wearer's head from both sides; the second elastic part can allow the temples to flex, avoiding excessive load on the wearer's ears when putting on or taking off the eyeglasses. Furthermore, the combination of the first and second elastic parts can alleviate the torsional force applied to the frame.

[0015] In this invention, the elastic forces of the first elastic part and the second elastic part should not interfere with each other's functions. For example, when the first elastic part functions to clamp the wearer's head from both sides to prevent the eyeglass frame from shifting, the second elastic part has an elastic force that prevents the eyeglass frame from shifting when it is subjected to impacts, etc.

[0016] Furthermore, the shape of the head, the position and height of the ears, etc., vary from wearer to wearer. Therefore, the optimal directions of the first direction of the first elastic part and the second direction of the second elastic part also vary from wearer to wearer. Therefore, when assembling the first elastic part and the second elastic part, the relative angle between the first direction and the second direction can be made variable, so that the first direction and the second direction can be set according to the situation of each wearer.

[0017] The material and shape of the first and second elastic portions are not limited, as long as they function as described in this invention. As claimed in claim 4, at least one of the first and second elastic portions should be formed by a leaf spring. Furthermore, as claimed in claim 5, at least one of the first and second elastic portions should be formed by multiple rod-shaped fittings. In this case, as claimed in claim 6, the multiple rod-shaped fittings should be twisted at the middle portion, positioning the first elastic portion on the side where the frame appears from the middle portion; and positioning the second elastic portion on the side where the temple appears from the middle portion. The cross-section of the rod-shaped fittings can be circular, oval, rectangular, or polygonal.

[0018] (Invention Effects)

[0019] The eyeglass frame of the present invention, through the biaxial elastic deformation of the first elastic part and the second elastic part, can elastically deform according to the shape of the head, which not only makes it easy to put on and take off the eyeglass frame, but also reduces the bending force transmitted to the frame and inhibits frame deformation. Furthermore, even when an impact force is applied to the eyeglass frame from the outside due to sports or other reasons, the first elastic part and the second elastic part can absorb the impact force, reducing the load and pain on the ears.

[0020] Therefore, this invention not only combines the advantages of rectangular and circular cross-section temples, but also solves the disadvantages of both. Attached Figure Description

[0043] The preferred embodiments of the eyeglass frame of the present invention will now be described in detail with reference to the drawings.

[0044] [First Implementation Method]

[0045] Figure 1 A first embodiment of the eyeglass frame relating to the present invention is shown in (a) as a plan view of one of the left and right temples and (b) as a side view of (a).

[0046] The eyeglass-shaped frame mentioned below refers to an eyeglass frame with a frame F that supports the lenses. One end of the left and right temples 1 is connected to the frame F via a hinge Fb on the post Fa, and can be folded freely towards the frame F. The other end of the left and right temples 1 forms a curved temple M, which can be hung along the wearer's ear Hb.

[0047] A first elastic portion 11 is formed at one end of the temple 1 (on the side of the hinge Fb) between the hinge Fb and the ear Hb, and a second elastic portion 12 is formed at the other end.

[0048] One end of the first elastic part 11 can be connected to the pile head Fa, the other end of the first elastic part 11 can be connected to one end of the second elastic part 12, and the other end of the second elastic part 12 can be connected to one end of the mirror temple M by brazing, laser welding, screws, etc. Furthermore, the first elastic part 11 and the second elastic part 12 can also be integrally formed by stamping, cutting, etc.

[0049] In this embodiment, a first elastic portion 11 and a second elastic portion 12 are formed by a leaf spring. The leaf spring is made of an elastic material such as β-type titanium alloy, stainless steel, or spring steel, and its cross-sectional shape is approximately rectangular. Bending forces are applied to the first elastic portion 11 and the second elastic portion 12 formed by the leaf spring at their respective ends, producing elastic flexural bending in their flat front and back directions, while no bending occurs in other directions.

[0050] Furthermore, a first elastic portion 11 is disposed at one end of the temple 1 (on the hinge Fb side), with the flat surface of the leaf spring facing a direction intersecting with the side of the wearer's head Ha (hereinafter referred to as the "first direction"); a second elastic portion 12 is disposed between the first elastic portion 11 and the temple M, with its flat front and back surfaces facing a direction intersecting with the front and back surfaces of the first elastic portion 11 (hereinafter referred to as the "second direction"). Moreover, in this embodiment, the angle between the first direction and the second direction is approximately a right angle.

[0051] By configuring the first elastic portion 11 and the second elastic portion 12 in this way, after the wearer places the eyeglass frame on their head H, the temples M are pushed outwards along the side of the head Ha. The resulting bending force causes the first elastic portion 11 to flex in the first direction. However, the second elastic portion 12 is restricted from flexing in directions other than the second direction. Because the first elastic portion 11 flexes in the first direction, such as... Figure 1 As indicated by symbols I and II in (a), the temples 1 extend outwards, allowing the eyeglass frame to fully accommodate the varying head widths of the wearer. Furthermore, the outwardly extending left and right temples 1 clamp the wearer's head H, preventing misalignment of the eyeglass frame.

[0052] Furthermore, when putting on or taking off eyeglass frames, the curved temple M moves along the ear Hb, and the temple M is pushed upward by the ear Hb. The bending force generated at this time causes the second elastic part 12 to flex, causing the temple M to move upward (see...). Figure 1 (b) Positions I and II). The first elastic portion 11 is restricted from flexing in directions other than the first direction. Therefore, the load and pain on the ear Hb can be reduced.

[0053] The eyeglass frame of the present invention, because the first elastic part 11 and the second elastic part 12 flex independently in different directions, can not only deform elastically in one axis, but also deform elastically according to the shape of the head by combining biaxial elastic deformation. Therefore, it is convenient to put on and take off the eyeglass frame, and can reduce the bending force transmitted to the frame F and suppress the deformation of the frame F. Furthermore, even when an impact force is applied to the eyeglass frame from the outside due to sports or other reasons, the first elastic part 11 and the second elastic part 12 can absorb the impact force, and reduce the load and pain on the ear Hb through the temple M.

[0054] [Second Implementation Method]

[0055] Figure 2 A second embodiment of the eyeglass frame of the present invention is shown in (a) as a partial plan view of the main part of the temple, and (b) and (c) as enlarged partial views of part A, one of the connecting parts, where (b) shows the state before connection and (c) shows the state after connection.

[0056] In this embodiment, one end of the first elastic part 11 is connected to the pile head Fa, the other end of the first elastic part 11 is connected to one end of the second elastic part 12, and the other end of the second elastic part 12 is connected to one end of the mirror foot M by a connecting part 13, which is composed of a threaded shaft 130 and a threaded hole 131.

[0057] Figure 2In (a), the connecting portion 13 shown by symbol A includes a threaded shaft 130 formed at the other end of the second elastic portion 12 and a threaded hole 131 formed at the other end of the mirror foot M, wherein the threaded shaft 130 can be screwed into the threaded hole 131.

[0058] The installation angle (orientation in the second direction) of the second elastic part 12 relative to the temple M can be changed by adjusting the length of the threaded shaft screwed into the threaded hole 131 of the threaded shaft 130. The screw-in length can be adjusted by changing the shaft length of the threaded shaft 130. As shown in the example, the screw-in length can be easily and freely adjusted by changing the thickness and number of washers 133 that can be freely attached and detached from the threaded shaft 130. The connecting parts 13 indicated by symbols B and C can also be constructed in the same way. By adjusting the screw-in length of the threaded shaft 130 at each of A, B, and C, the intersection angle of the first and second directions can be adjusted to the optimal angle according to the individual needs of the eyeglass frame wearer.

[0059] [Third Implementation Method]

[0060] Figure 3 A third embodiment of the eyeglass frame relating to the present invention is shown in (a) as a partial plan view of the main part of the temple and (b) as a side view thereof.

[0061] In this embodiment, the temple 2 of the eyeglass frame has a first elastic portion 21 and a second elastic portion 22, which are formed by multiple elastic rod-shaped fittings 21a and 22a, replacing the leaf spring-shaped first elastic portion 11 and second elastic portion 12 of the temple 1 in the previous embodiment.

[0062] Similar to the previous embodiment, one end of the first elastic part 21 is connected to the pile head Fa (see...). Figure 1 On the first elastic part 21, the other end of the second elastic part 22 is connected to one end of the temple M. The other end of the first elastic part 21 is connected to one end of the second elastic part 22 by a plate-shaped or block-shaped connecting part 23.

[0063] Furthermore, the connecting parts 23, the connecting parts on the Fa side of the pile head, and the connecting parts on the M side of the mirror pin can also be connected to... Figure 2 The connecting portion 13 shown in the second embodiment is also configured similarly.

[0064] In the first elastic section 21, multiple rod-shaped fittings 21a (two in the example in the figure) are arranged in a plane facing the first direction, and in the second elastic section 22, multiple rod-shaped fittings 22a (two in the example in the figure) are arranged in a plane facing the second direction.

[0065] By configuring the rod-shaped fittings 21a and 22a in this way, similar to the leaf spring-shaped first elastic part 11 and second elastic part 12 in the previous embodiment, in the first elastic part 21, the multiple rod-shaped fittings 21a only elastically flex in the front and back (first direction) of the plane on which they are arranged; in the second elastic part 22, the multiple rod-shaped fittings 22a only elastically flex in the front and back (second direction) of the plane on which they are arranged, and will not flex in other directions.

[0066] [Example of a variant of the third implementation]

[0067] Figure 4 Examples of variations relating to the third implementation include (a) a partial plan view of the main portion of the temple and (b) a side view thereof.

[0068] The temple 3 in this embodiment is the same as the temple 2 in the third embodiment, with the first elastic portion 31 and the second elastic portion 32 formed by rod-shaped fittings. The difference from the temple 2 in the third embodiment is that the rod-shaped fitting is a single rod-shaped fitting 31a extending from the first elastic portion 31 to the second elastic portion 32. Furthermore, multiple rod-shaped fittings 31a (two in the example shown in the figure) are simultaneously arranged to form the first elastic portion 31 and the second elastic portion 32.

[0069] In the first elastic section 31, the front portions of multiple rod-shaped fittings 31a are arranged in a plane facing the first direction; in the second elastic section 32, the front portions of multiple rod-shaped fittings 31a are arranged in a plane facing the second direction.

[0070] Between the first elastic part 31 and the second elastic part 32, a plate-shaped or block-shaped intermediate part 33 is provided, through which multiple rod-shaped fittings 31a penetrate through a through hole (not shown) formed in the intermediate part 33. Furthermore, the multiple rod-shaped fittings 31a are twisted at the point where they penetrate the intermediate part 33, turning from the first direction to the second direction.

[0071] In this variant example, by configuring the rod-shaped fittings 31a, the first elastic portion 31 and the second elastic portion 32 in this way, they serve the same function as the first elastic portion 21 and the second elastic portion 22 in the third embodiment. That is, in the first elastic portion 31, the multiple rod-shaped fittings 31a only elastically flex in the front and back (first direction) of the plane in which they are arranged; in the second elastic portion 32, the multiple rod-shaped fittings 31a only elastically flex in the front and back (second direction) of the plane in which they are arranged, and do not flex in other directions.

[0072] In the third embodiment and its variant examples, the temples 2 and 3 are similar to those in the first embodiment. After the wearer places the eyeglass frame on their head H, the temples M are pushed outwards along the side of the head Ha. The resulting bending force causes the first elastic parts 21 and 31 to flex in a first direction. However, the second elastic parts 22 and 32 are restricted from flexing in directions other than the second direction. Because the first elastic parts 21 and 31 flex in the first direction, the temples 2 and 3 expand outwards, allowing the eyeglass frame to fully accommodate the varying head widths of the wearer. Furthermore, the outwardly expanding left and right temples 2 and 3 clamp the wearer's head H, preventing misalignment of the eyeglass frame.

[0073] Furthermore, when putting on or taking off eyeglass frames, the curved temple M moves along the ear (Hb), and is pushed upwards by the ear. The resulting bending force causes the second elastic parts 22 and 32 to flex, moving the temple M upwards. However, the first elastic parts 21 and 31 are restricted from flexing in directions other than the first direction. Therefore, the load and pain on the ear (Hb) can be reduced.

[0074] The preferred embodiments of the present invention have been described above, but the embodiments of the present invention are not limited to the above description.

[0075] For example, in the above description, although the first elastic parts 11, 21, 31 and the second elastic parts 12, 22, 32 are formed of metals such as β-type titanium alloy, stainless steel, and spring steel, other metals and resins such as polyamide can also be used as long as they are elastic.

[0076] Furthermore, although in the first embodiment, the first elastic portion 11 and the second elastic portion 12 are flat leaf springs that appear approximately rectangular in plan view, other plan view shapes such as oval or cloud-shaped are also acceptable as long as they serve the same function. Wave-shaped leaf springs and leaf springs that are partially or entirely bent in one direction are also acceptable. Furthermore, in the third embodiment and its variant examples, although the rod-shaped accessories 21a, 31a, and 22a are arranged in the same plane, when there are three or more rod-shaped accessories 21a, 31a, and 22a, as long as the bending directions of the first elastic portions 21 and 31 and the second elastic portions 22 and 32 point towards the first and second directions respectively, they do not necessarily have to be arranged in the same plane.

[0077] Furthermore, in the above description, although the first elastic portions 11, 21, and 31 face the first direction and the second elastic portions 12, 22, and 32 face the second direction that intersects them, it is also possible to make the first elastic portions 11, 21, and 31 face the second direction and the second elastic portions 12, 22, and 32 face the first direction that intersects them. In this way, the distance between the first elastic portions 11, 21, and 31, which elastically deform in the vertical direction, and the ear (Hb) can be greater than that of the temples 1, 2, and 3 in the above embodiment. Even when the eyeglass frame is subjected to impact forces during exercise, the load and pain on the ear (Hb) can be further reduced.

[0078] Furthermore, although the first and second elastic parts are described above as being located on the temples, it is not necessary for both to be located on the temples. For example, the first elastic part can be located on the post Fa of the frame F, and the second elastic part can be located on the temples. In this case, the hinge Fb of the post Fa can be used as a spring hinge, and this spring hinge can be used as the first elastic part.

[0079] Furthermore, the present invention may also combine the first elastic part 11 of the first embodiment, the first elastic part 21, 31 of the third embodiment or its variant examples with the second elastic part 12 of the first embodiment, the second elastic part 22, 32 of the third embodiment or its variant examples as appropriate.

[0080] (Industrial applicability)

[0081] The eyeglass-shaped frame of the present invention can be used as an eyeglass-shaped frame to fix eyeglass lenses and masks to the frame, and can also be used as an eyeglass-shaped frame to support functional accessories such as wearable devices represented by lamps, cameras, and small displays.
