Description

  The present invention relates to additional glasses for clear vision that can be used simply by being superimposed on regular glasses used by a wearer.

  As is well known, when a fine character is seen or a fine work is performed, it is usual to use a large magnifying glass (loupe) in hand or use a stand type magnifying glass.

  However, since the magnifying lens simply enlarges characters / objects, when a person who is correcting vision uses the magnifying glass as described above, it is necessary to use it together with regular glasses.

  In particular, those who use a magnifying glass often have presbyopia (so-called presbyopia) that is unable to focus on objects at short distances due to aging, and they must be vivid even if they use the magnifying glass with their naked eyes. In order to obtain clarity, it is necessary to use reading glasses or bifocal glasses.

  As described above, those who have corrected vision can obtain clarity by using a magnifying glass and regular glasses, but hand-held magnifying glass is inconvenient because it cannot be used with one hand. There was a problem of getting in the way because it was large.

  In order to solve these problems, conventionally, there has been known a technique related to a spectacle-type magnifying glass that is used by being superimposed on regular glasses. For example, Patent Document 1 discloses a magnifying glass provided with a temple on a plastic convex lens and attached to the regular glasses through a clip disposed at the tip of the temple. There is a problem that the wearer feels heavy with a long distance. Patent Document 2 discloses a technique related to a spectacle-type magnifying glass that is reduced in weight to solve the above-described problem, but has a problem that the position of the magnifying lens cannot be adjusted.

  Furthermore, Patent Document 3 discloses a structure in which a magnifying lens is attached via an arm composed of a plurality of arm pieces in order to solve the problem of position adjustment.

  However, although the spectacle-type magnifiers of Patent Document 2 and Patent Document 3 are lighter than those of Patent Document 1, the nose pad of the magnifier is fixed via a support member, so the mounting position is The problem is that the wearer feels heavier because it is positioned lower than the pad of the regular glasses and abuts against the wearer's nose tip when worn.

  The present invention has been made in view of the above-described problems with conventional spectacle-type magnifiers, and the purpose of the present invention is to put the additional glasses for clear vision on the wearer's glasses. It is an object of the present invention to provide clear vision additional glasses that are difficult to feel weight when used, and that can adjust the lens to a position according to their own visual acuity.

  Means adopted by the present inventors for solving the above-described problems will be described with reference to the accompanying drawings.

That is, the additional glasses 1 that are used over the lenses L and L of the regular glasses G that the wearer regularly uses,
A lens holding portion 3 is provided at the central portion of the brow bar-like support member 2 along the forehead portion of the wearer so that the holding angle can be adjusted. A nose pad 21 protrudes from the inside of the blow bar-like support member 2, and the nose pad 21 is brought into contact with the nose of the wearer so that the magnifying loupe 4 is placed on the lenses LL of the regular glasses G. In this way, the character / object can be seen enlarged.

  Further, the present invention employs a technical means in which temples T and T are foldably attached to both ends of the blow bar-like support member 2.

  In addition, the present invention employs a technical means in which the nose pad 21 protruding from the inside of the blow bar-like support member 2 is configured with a member that can be adjusted according to the shape of the wearer's nose.

  In the present invention, a take-out piece 31 is disposed between the lens holding portion 3 and the blow bar-like support member 2, and a hinge portion 3 a is provided between the carry-out piece 31 and the blow bar-like support member 2. The technical means of forming a hinge part 3b between the lens holding part 3 and the lens holding part 3 was adopted.

  In addition, the present invention employs a means in which a nose-shaped depression 41 is formed at the lower edge of the magnifying loupe 4 and at the portion that touches the wearer's nose.

  In the present invention, the nose pad 21 protrudes from the inside of the blow bar-like support member 2 so that the nose pad can be brought into contact with the nasal root portion, and clearly compared with the case where it is brought into contact with the nose tip portion. The weight of the additional glasses can be reduced.

  Furthermore, by bringing the nose pad 21 into contact with the root of the nose, the distance between the magnifying loupe 4 and the eye of the wearer, that is, the distance between the corneal vertices can be shortened, and the field of view through the magnifying loupe 4 can be widened. Is possible.

  In addition, by attaching the magnifying loupe 4 via the lens holding part 3 that is provided so that the holding angle is adjustable, the magnifying loupe 4 can be adjusted to the optimum forward tilt angle for the wearer, and the visibility is improved. It becomes possible to improve.

  In addition, the temples T and T can be folded at both ends of the brow bar-like support member 2 so that the weight of the additional glasses for clear vision can be distributed to the nose pad 21 and the temples T and T and is easy to carry. It becomes possible to.

  In the present invention, by constructing the nose pad 21 with a member that can be adjusted according to the shape of the wearer's nasal root, it becomes possible to use the additional glasses for clear vision stably.

  In the present invention, by providing the take-out piece 31 between the lens holding part 3 and the blow bar-like support member 2, two hinge parts 3a and 3b can be formed. The angle can be adjusted.

  The lower edge of the magnifying loupe 4 is formed on the part of the wearer's nose that touches the wearer's nose 41, so that the lower edge of the lens is attached to the wearer when using clear glasses or when adjusting the lens position. It is possible to eliminate the uncomfortable feeling of interfering with the nose bridge part.

It is a perspective view showing additional glasses for clear vision in the example of the present invention. It is an expansion perspective view showing the taking-out part structure in the Example of this invention. It is a perspective view showing the nose pad attachment method of the Example in this invention. It is a side view showing the state where the additional glasses for clear vision in the embodiment of the present invention was superimposed on the regular glasses. It is an expansion perspective view showing the taking-out part structure of the modification in this invention.

  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

An embodiment of the present invention will be described with reference to FIG. Reference numeral 1 in the figure designates additional glasses. The additional glasses 1 are provided with a blow bar-like support member 2 having temples T and T attached to both ends, and a holding angle adjustable on the support member 2. The lens holding unit 3 is provided and an magnifying loupe 4 attached to the tip of the lens holding unit 3 (see FIG. 1).
The blow bar-shaped support member 2, the temple T / T, and the lens holding portion 3 are made of a nylon resin material, and the magnifying loupe uses a 1.6 × magnification lens made of an acrylic resin material.
