Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable magnifying glass, and more specifically to a magnifying glass using a convex lens in the form of a transverse semi-cylindrical transparent body.

[Conventional technology]

A magnifying glass using a convex lens of a horizontal semi-cylindrical transparent body is already known, and is particularly used for reading computer programs and books by enlarging them line by line. However, most conventional magnifying glasses of this type have a length of 15 cm or more to match the length of the lines in books, etc., and are inconvenient for portable use.

[Problem that the invention aims to solve] Therefore, it is conceivable to shorten this to about 10 to 14 cm and attach a locking clip to the end to lock it in a pocket, etc., but in this case, the pocket In order to easily insert a fabric such as a cloth between the clip and the transparent body, the tip of the clip needs to be slightly spaced apart from the transparent body. Since the flat bottom surface of the horizontally oriented semi-cylindrical transparent body is used in contact with books, etc., it is not possible to form a protruding clip on this flat bottom side, and it is necessary to form it on the upper curved surface of the transparent body. do not have.

However, it is not preferable to attach such a protruding clip to this type of transverse semi-cylindrical transparent magnifying glass because it impairs ease of use. In addition, with this type of magnifying glass, for example, when the magnifying glass is placed horizontally along the lines in order to enlarge horizontally written text, if the eye position is shifted upward or downward on the page, the clips and the lines are aligned. This causes a large shift in the relative position of the clip, which can lead to people being confused by the position of the clip and misreading the line they are reading.

Taking the above facts into consideration, the present invention has been designed to avoid misreading lines due to large deviations in the relative positions of clips and lines, without impairing the ease of use based on the simple shape of the horizontally oriented semi-cylindrical transparent body. It is an object of the present invention to provide a portable magnifying glass of this kind that does not cause any problems.

[Means for solving problems]

In order to achieve the above object, the portable magnifying glass according to the present invention has the locking piece of the locking clip extending non-protrudingly on the flat bottom side of the transverse semi-cylindrical transparent body, and A recess was formed in the flat bottom surface of the transparent body facing the stopper. Here, "non-prominent" means
This does not mean that the locking piece does not protrude from the flat bottom surface of the transparent body at all, but includes a protrusion that does not substantially cause wobbling when the flat bottom surface of the transparent body is placed on a flat surface. meaning.

[Effect]

In the present invention having the above configuration, in a normal state, the locking piece of the locking clip is in close contact with the flat bottom side of the transverse semi-cylindrical transparent body in a non-protruding manner and does not get in the way; When locking to cloth, paper, etc. in a pocket, press the locking piece located in the recess formed on the flat bottom of the transparent body with your finger, and the locking piece will warp and its tip side will be tilted upward. This makes it difficult for the tip of the locking piece to come into contact with the transparent body, making it easier to insert cloth, paper, etc. into the pocket.

〔Example〕

FIG. 1 is an exploded perspective view showing an embodiment of a portable magnifying glass according to the present invention.

10 is a horizontal semi-cylindrical transparent body which is the main body of the magnifying glass, and is made of transparent synthetic resin such as acrylic resin;
Since its cross section is semicircular, it acts as a convex lens.

Since this magnifying glass is used by touching the paper surface of a book, etc., the bottom surface of the transparent body 10 is flat bottom surface 1.
It is formed as 2.

Reference numeral 20 denotes a locking clip for locking this magnifying glass to a breast pocket of clothes, a piece of paper, etc., and the locking clip 20 consists of a support portion 22 and a flat plate-shaped locking piece 24. The locking clip 20 in this embodiment is made of metal, for example, by punching a metal plate into a T-shape, but the material is not limited to this as long as the locking piece 24 is flexible. . however,
It is desirable to use a locking piece 24 that is as thin as possible and has sufficient strength. As shown in FIG. 2A, the locking clip 20 has its support portion 22 fitted into the end of the transparent body 10 such that the locking piece 24 runs along the flat bottom surface 12 of the transparent body 10.

A concave portion 14 is formed in the flat bottom surface 12 of the transparent body 10, and the concave portion 14 is provided with a locking piece when the locking clip 20 is attached to the end of the transparent body 10, as shown in FIG. 2A. 24.

Next, the operation of this embodiment will be explained.

In a normal state, as shown in FIG. 2A, the plate-shaped locking piece 24 extends non-protrudingly along the flat bottom surface 12. It can be used while in contact with the In this case, since the locking piece 24 is in close contact with the paper surface, it serves as an index indicating the corresponding row.

Then, as shown in FIG. 2B, the portion of the locking piece 24 facing the recess 14 of the flat bottom surface 12 is indicated by the arrow 30.
When pressed in the direction of , the locking piece 24 is warped and the tip 24A of the locking piece 24 is separated from the flat bottom surface 12 of the transparent body 10, so that cloth, paper, etc. from the pocket can be easily inserted through this gap. become.

Therefore, it can be carried in the same manner as a fountain pen or the like, and furthermore, paper can be inserted between the locking piece 24 and the flat bottom surface 12, so as shown in FIG. It is also possible to insert the magnifying glass from the side edge of the paper and use it with the magnifying glass fixed to the paper surface.

FIG. 4 is a plan view showing an embodiment in which the magnifying glass is provided with scales along the longitudinal direction. In this embodiment, the scale 42 is a transverse semi-cylindrical transparent body 4.
Although it is attached to the flat bottom surface of the transparent body 40, it may also be attached to the side of the curved surface of the transparent body 40.

5A and 5B, a convex edge 54 along the longitudinal direction is formed on the transverse semi-cylindrical transparent body 50,
FIG. 7 is a plan view and an end view showing an embodiment in which a scale 52 is attached to this projecting edge portion 54. FIG.

In the above embodiment, the locking piece of the locking clip is described as having a flat plate shape, but the tip part is rounded and thick, and this part is depressed by providing a recess in the flat bottom surface of the transparent body. You can do it like this,
Similarly, the vicinity of the base of the locking piece may be thickened to provide strength, and this portion may be recessed into the flat bottom surface of the transparent body.

[Effect of idea]

As explained above, the portable magnifying glass according to the present invention has the locking piece of the locking clip extended non-protrudingly on the flat bottom side of the horizontal semi-cylindrical transparent body. The simple shape of the clip does not impair its ease of use, and when used normally as a magnifying glass, the locking piece acts as an indicator to indicate the line to be read, so there is no possibility of large deviations in the relative position between the clip and the line. There is no possibility of misreading lines based on . Furthermore, when using it as a magnifying glass, it can also be used in a fixed state by sandwiching it between pieces of paper.

Furthermore, in the present invention, since a recess is formed in the flat bottom surface of the transparent body opposite to which the locking piece of the locking clip faces, the operation of pinching cloth, paper, etc. from the pocket between the locking piece and the transparent body is facilitated. This can be done extremely easily by simply pressing the locking piece facing the recess with your finger.

In this way, the magnifying glass according to the present invention has a locking clip that not only functions when being carried, but also functions when used as a magnifying glass, making it extremely useful in practice.
