Description

[Technical Field]

[0001] The present invention relates to posture corrective eyeglasses, and more particularly to posture corrective eyeglasses for use in a sitting position. [Background technology]

[0002] When operating a mobile device or reading a book while sitting on a chair or sofa, users tend to lower their head and lean forward, or hunch over and slouch. Continuing to maintain these postures can have a negative impact on both the mind and body, so it is advisable to correct this posture.

[0003] As a technology for correcting incorrect posture, posture-correcting glasses are proposed in Patent Document 1. These posture-correcting glasses are equipped with a posture detector such as a tilt sensor, distance sensor, and level, lenses with a liquid crystal light-adjusting function, notification means such as a speaker, vibrator, and electric bell, and a battery for operating them.

[0004] The posture corrective glasses disclosed in Patent Document 1 can be used in daily life. When a posture detector installed in the glasses detects an undesirable posture of the user, the lenses with a photochromic function darken or a notification is issued, thereby encouraging the user to adopt a correct posture. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Registered Utility Model No. 3232059 Summary of the Invention [Problem to be solved by the invention]

[0006] The posture corrective glasses disclosed in Patent Document 1 are powered by a small battery installed in the frame, which necessitates frequent battery charging or battery replacement, making them inconvenient for everyday use. Furthermore, depending on the weight of the posture detector, notification means, and battery, this can place strain on the user's ears, nose, head, and other parts of the body, making the glasses too heavy for everyday use. Furthermore, the inclusion of various small electronic devices and batteries makes the glasses themselves expensive.

[0007] SUMMARY OF THE INVENTION Therefore, a primary object of the present invention is to provide posture correcting eyeglasses that are lightweight, inexpensive to manufacture, and convenient to use. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, posture correcting glasses designed specifically for a seated posture are provided, which include a frame having at least an upper edge and a lower edge, a lens, a connecting part that connects the lower edge of the frame to the lower part of the lens so that the lens can be opened and closed forward relative to the frame with the lower part as a fulcrum, and a holding part that detachably holds the upper part of the lens to the upper edge of the frame, and the holding part is configured so that when the frame is tilted forward to a predetermined angle, the holding part releases the lens from its hold, causing the lens to open forward relative to the frame.

[0009] In this invention, when the user is in the correct posture, the holder holds the top of the lens in contact with the upper edge of the frame, and the lens stands upright in front of the frame, as if covering it. In this state, the lens does not obstruct the user's field of vision, allowing the user to see through the lens. However, when the user leans forward, the frame attached to the user's ear also leans forward, and the weight of the lens generates a moment centered on the lower part of the lens, exerting a force in a direction that pulls the top of the lens away from the upper edge of the frame. As the forward tilt angle of the frame increases, this moment, and therefore the force in the pulling direction, increases. The holder keeps the top of the lens in contact with or close to the upper edge of the frame until the user leans forward and assumes an undesirable posture, i.e., until the forward tilt angle of the frame reaches a predetermined angle. However, once the forward tilt angle of the frame reaches a predetermined angle, the holder, which holds the top of the lens, can no longer withstand the pulling force, and the holder releases the top of the lens. The lens then swings forward, using its lower part as a fulcrum. In other words, the lenses are tilted forward from the frame. For the user, lenses tilted forward from the frame obstruct vision, so they manually return the lenses to the frame and correct their posture. As a result, the user's hunched posture is eliminated, and their sitting posture is effectively corrected. These posture-correcting glasses are simply constructed using mechanical elements, making them lightweight, inexpensive to manufacture, and convenient.

[0010] Preferably, the holder includes a magnet attached to either the top of the lens or the upper edge of the frame, and a magnetic member or magnet attached to the other. In this case, the holder can hold the lens upright by utilizing the attractive force between the magnet and the magnetic member or between the magnets. The attractive force can be adjusted by changing the size of the magnet or the magnetic member, or the strength of the magnetic force, and this allows for easy adjustment of the angle of the frame when the lens falls significantly forward of the frame.

[0011] Preferably, the holder includes a stopper portion provided on the upper edge of the frame that can lock the upper portion of the lens and swing relative to the upper edge of the frame. In this case, the stopper portion locks the upper portion of the lens, thereby holding the lens in an upright position. Furthermore, by changing the length or weight of the stopper portion, the predetermined angle of the frame can be easily adjusted when the lens falls significantly forward from the frame. [Effects of the Invention]

[0012] According to the present invention, posture correcting glasses can be obtained which are lightweight, inexpensive to manufacture, and convenient. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] Referring to FIG. 1, posture-correcting glasses 10 according to one embodiment of the present invention are glasses designed specifically for use in a sitting position, and include a frame 12 and a pair of lenses 14 .

[0016] The frame 12 includes a pair of limbs 16, a bridge 18 connecting the pair of limbs 16, and a pair of temples 20 foldably attached to the pair of limbs 16. Each limb 16 includes an upper edge 16a and a lower edge 16b. That is, the frame 12 includes an upper edge 16a and a lower edge 16b. Any frame can be selected as the frame 12, such as a metal frame or a plastic frame, but in this embodiment, the frame is made of a plastic frame.

[0017] The lenses 14 include lenses for correcting the user's vision and non-prescription lenses.

[0018] 2, the lower edge 16b of the rim 16 (frame 12) and the lower part of the lens 14 are connected by a connecting part 22 so that the lens 14 can be opened and closed forward relative to the frame 12, with the lower part as a fulcrum. The connecting part 22 is made up of a hinge attached to the lower edge 16b of the rim 16 and the lower part of the lens 14, and the lens 14 is attached to the frame 12 via the connecting part 22 so that it can be opened and closed forward. Therefore, the lens 14 can swing forward with the connecting part 22 as a fulcrum.

[0019] An upper portion of the lens 14 is removably held by a holder 24 on the upper edge 16a of the rim 16 (frame 12). The holder 24 is configured so that when the frame 12 is tilted forward to a predetermined angle, i.e., when the forward tilt angle A of the frame 12 reaches a predetermined angle, the holder 24 releases its hold on the lens 14, causing the lens 14 to open forward relative to the frame 12. In this embodiment, the holder 24 includes a magnet 24a provided on the upper edge 16a of the rim 16 (frame 12) and a magnetic member 24b provided on the upper portion of the lens 14 and capable of being attracted to the magnet 24a. Therefore, the magnitude of the magnetic force of the holder 24, which attracts the magnetic member 24b to the magnet 24a, is set so that when the frame 12 is tilted forward to the predetermined angle, the lens 14 is released from its hold by the magnetic force of the holder 24, causing the lens 14 to open forward relative to the frame 12.

[0020] The forward tilt angle A of the frame 12 refers to the forward tilt angle of the frame 12 relative to the vertical line V; in other words, when viewed from the side of the posture correcting glasses 10, it refers to the angle that an imaginary line L passing through the front-to-back midpoint of the upper edge 16a of the frame 12 and the front-to-back midpoint of the lower edge 16b makes with the vertical line V (see Figure 2).

[0021] The operation of the posture corrective glasses 10 will be described with reference to FIG.

[0022] As shown in Figure 3(a), when the frame 12 and therefore the posture corrective glasses 10 are tilted forward, gravity G acting on the lens 14 generates a moment M centered on the connecting part 22, which generates a force T that separates the upper edge 16a of the frame 12 from the top of the lens 14. When the tilt of the frame 12 and therefore the posture corrective glasses 10 reaches a predetermined angle or more, the increase in moment M causes the separating force T to become greater than the suction force S of the holding part 24, and as shown in Figure 3(b), the upper edge 16a of the frame 12 and the top of the lens 14 are separated, and the lens 14 swings forward with the connecting part 22 as a fulcrum, causing the lens 14 to fall far forward of the rim 16.

[0023] When wearing such posture corrective glasses 10 and sitting on a chair or sofa, operating a mobile device or reading a book in one hand, as shown in Figure 4(a), in the normal state, the upper part of the lens 14 is attached to the upper edge 16a of the frame 12 by the holder 24, and the lens 14 is held in a predetermined position on the frame 12 in an upright position, covering the front of the rim 16. The user can see through the lens 14.

[0024] On the other hand, as shown in Figure 4(b), when the user leans forward and assumes an undesirable posture, i.e., when the frame 12 and therefore the posture corrective glasses 10 are tilted at a predetermined angle or more, the lenses 14 lean forward significantly from the frame 12, causing the edges of the lenses 14 to appear in the field of view and creating a blind spot. In this state, the lenses 14 obstruct the field of view, and the user is prompted to return to a correct posture.

[0025] With these posture-correcting glasses 10, when the user is in a correct posture, the holder 24 holds the upper portion of the lens 14 in contact with the upper edge 16a of the frame 12, and the lens 14 stands upright in front of the frame 12, as if covering it. In this state, the lens 14 does not obstruct the user's field of vision, allowing the user to see objects through the lens 14. However, when the user leans forward, the frame 12 attached to the user's ear also leans forward, and the weight of the lens 14 generates a moment M centered on the lower portion of the lens 14, applying a force T in a direction that pulls the upper portion of the lens 14 away from the upper edge 16a of the frame 12. As the forward tilt angle A of the frame 12 increases, this moment M, and therefore the force T in the pulling direction, increases. The holder 24 holds the upper portion of the lens 14 in contact with the upper edge 16a of the frame 12 until the user leans forward and assumes an undesirable posture, i.e., until the forward tilt angle A of the frame 12 reaches a predetermined angle. However, when the forward tilt angle A of the frame 12 reaches a predetermined angle, the holding portion 24 holding the upper portion of the lens 14 can no longer withstand the pulling force T, and the holding portion 24 releases its hold on the upper portion of the lens 14. The lens 14 then opens forward, with its lower portion as a fulcrum. That is, the lens 14 falls significantly forward from the frame 12. For the user, the lens 14 falling significantly forward from the frame 12 obstructs their field of vision, so they manually return the lens 14 to the frame 12 and correct their posture. As a result, the user's slouched posture is eliminated, and their sitting posture can be effectively corrected. Because the posture-correcting eyeglasses 10 are simply constructed using mechanical elements, they can be manufactured at low cost and are convenient.

[0026] The holder 24 can hold the lens 14 in an upright position by the attraction force S between the magnet 24a and the magnetic member 24b. The attraction force S can be adjusted by changing the size of the magnet 24a and the magnetic member 24b, the strength of the magnetic force, etc., and this makes it possible to easily adjust the predetermined angle of the frame 12 when the lens 14 falls significantly forward from the frame 12.

[0027] The posture corrective glasses may also be configured as shown in FIG.

[0028] 5 is configured in the same manner as the posture corrective glasses 10, except that it uses a stopper portion 26 instead of the holder 24. The stopper portion 26 is provided on the upper edge portion 16a of the rim 16 (frame 12) so as to be able to lock the upper portion of the lens 14 and to be able to swing relative to the upper edge portion 16a of the rim 16 (frame 12), and functions as a holder.

[0029] 6, the stopper portion 26 includes a hinge portion 28 and a strip-shaped locking portion 30. The locking portion 30 is attached to the upper edge portion 16a of the rim 16 (frame 12) via the hinge portion 28, and can swing around the hinge portion 28.

[0030] The size and weight of the stopper portion 26 are set so that when the frame 12 is tilted forward to a predetermined angle, the stopper portion 26 releases the hold of the lens 14 and the lens 14 opens forward relative to the frame 12. In other words, the holding force Sa of the stopper portion 26 is determined by the length and weight of the stopper portion 26.

[0031] The operation of the posture correcting glasses 10a will be described with reference to FIG.

[0032] As shown in FIG. 7(a), when the frame 12 and thus the posture-correcting glasses 10a are tilted forward, the weight of the lens 14 generates a moment M centered on the connecting portion 22, generating a force T that opens the stopper portion 26 and separates the upper edge portion 16a of the frame 12 from the upper portion of the lens 14. Until the tilt of the frame 12 and thus the posture-correcting glasses 10a reaches a predetermined angle, the retaining portion 30 of the stopper portion 26 maintains the lens 14 in a retained state due to the holding force Sa applied from the stopper portion 26 to the lens 14. Therefore, until the tilt of the frame 12 and thus the posture-correcting glasses 10a reaches a predetermined angle, the upper portion of the lens 14 is maintained in contact with the upper edge portion 16a of the rim 16 (frame 12), or even if the retaining portion 30 is pushed forward, the upper portion of the lens 14 is maintained in close proximity to the upper edge portion 16a of the rim 16 (frame 12). When the tilt of the frame 12 and thus the posture corrective glasses 10a reaches a predetermined angle or more, the moment M increases, causing the pulling force T to exceed the holding force Sa of the stopper portion 26, and as shown in Figure 7(b), the stopper portion 26 releases the hold of the lens 14, causing the lens 14 to swing forward with the connecting portion 22 as a fulcrum, and the lens 14 falls far forward of the rim 16.

[0033] According to the posture corrective eyeglasses 10a, the stopper portion 26 can hold the lens 14 in an upright position by engaging the upper portion of the lens 14. In addition, by changing the length and weight of the stopper portion 26, the predetermined angle of the frame 14 when the lens 14 falls significantly forward from the frame 12 can be easily adjusted.

[0034] The posture corrective glasses according to the present invention can be used not only when operating a mobile terminal or reading a book while holding it in one's hand, but also when reading or writing at a desk.

[0035] In the above embodiment, the holder 24 includes a magnet 24a provided on the upper edge 16a of the rim 16 (frame 12) and a magnetic member 24b provided above the lens 14, but this is not limiting. The holder may include a magnetic member provided on the upper edge 16a of the rim 16 (frame 12) and a magnet provided above the lens 14. The holder may also include a magnet provided on the upper edge 16a of the rim 16 (frame 12) and a magnet provided above the lens 14. [Explanation of symbols]
