Description

The present invention relates to a magnifying glass device attached to an information display device worn on the wrist.

In recent years, wristwatch-type mobile information terminals have become popular and widely used. This portable information terminal is used by being worn on the wrist, and the information display surface, which corresponds to the dial of a wristwatch, is composed of a touch panel, and information is displayed on this touch panel. By operating the touch panel, the user can select and display the necessary information.

A large amount of information can be displayed on the information display screen of a mobile information terminal. However, this portable information terminal is the same size as a wristwatch, and the displayed characters and graphics are small, which may make it difficult for some users to read. In such a case, the user can display larger characters, figures, etc. by operating the touch panel. However, this reduces the amount of information displayed on one screen and requires frequent scrolling. In order to make text and graphics easier to read without reducing the amount of information displayed on a single screen, you can use a magnifying glass. Furthermore, not only mobile information terminals but also ordinary wristwatches can be used to make the dial easier to read using a magnifying glass. Therefore, it has been proposed to attach a magnifying glass to an information display device worn on the wrist, such as a wristwatch.

2. Description of the Related Art As a wristwatch equipped with a magnifying glass, one in which a magnifying glass is coupled to a wristwatch body with a hinge is known (see Patent Document 1). The wristwatch disclosed in Patent Document 1 has a magnifying glass hinged to the edge of the dial. However, the loupe of the wristwatch disclosed in Patent Document 1 is used to magnify and view things other than the dial, and it is difficult to magnify and view the dial.

Furthermore, there is known a wristwatch equipped with a magnifying glass in which a convex lens is connected to the wristwatch body with a screw (see Patent Document 2). In the wristwatch disclosed in Patent Document 2, a circular convex lens is removably connected to the edge of a circular dial with a screw. Therefore, by removing the convex lens, it is possible to enlarge the dial. However, in order to view the dial enlarged, it is necessary to remove the convex lens, which requires the cumbersome operation of rotating the convex lens many times. Furthermore, if the convex lens is removed from the watch body, there is a possibility that it will be lost.

First, the information display device 90 to which the magnifying glass device 1 is attached will be described. As shown in FIG. 1, the information display device 90 is shaped like a wristwatch and includes an information display body 91, and an upper belt 92 and a lower belt 93 that extend vertically from the information display body 91, respectively. The information display device 90 is attached to the user's wrist by wrapping the upper belt 92 and the lower belt 93 around the user's wrist. The information display body 91 has a display surface 91a, and information provided to the user is displayed on the display surface 91a. The display surface 91a is composed of a touch panel, and the user operates the touch panel to select information to be displayed.

As shown in FIG. 1, the magnifying glass device 1 includes an arm member 10 and a magnifying glass 20 as main components. The arm member 10 is composed of frames 11 and 12, and one end 10a thereof is coupled to an information display device 90 via a coupling means 30. Further, a magnifying glass 20 is coupled to the other end 10b of the arm member 10. The coupling means 30 is coupled to the upper belt 92 of the information display device 90. Although the method of coupling the coupling means 30 and the upper belt 92 can be arbitrarily selected, the illustrated coupling means 30 is coupled so as to wrap around the cross section of the upper belt 92, and is removable. As another configuration of the coupling means 30, it is also possible to have a pair of members extending in the width direction of the upper belt 92, and to sandwich the upper belt 92 from the front and back, so that the coupling can be removably coupled. It is also possible to integrate the coupling means 30 and the upper belt 92.

Next, the magnifying glass device 1 will be further explained based on FIG. 2. The frames 11 and 12 constituting the arm member 10 extend in the vertical direction as shown in FIG. 2(a), and one end of each frame is rotatably coupled to the coupling means 30. The frames 11 and 12 are coupled to both ends of the coupling means 30 in the width direction, and are spaced apart from each other in the left and right directions so that the display surface 91a of the information display body 91 can be seen. Further, as shown in FIG. 2(b), the frames 11 and 12 are curved in side view and have a convex shape in the front direction. Further, the frames 11 and 12 are coupled to the coupling means 30 by a hinge (not shown) so as to rotate about a rotation axis R1 extending in the left-right direction in FIG. 2(a). At the joints between the frames 11, 12 and the coupling means 30, friction acts so that the frames 11, 12 can remain stationary at any rotational position.

A magnifying glass 20 is rotatably coupled to the other end of each of the frames 11 and 12. The illustrated magnifying glass 20 has a rectangular outer shape and a convex lens shape at the center, but any shape that allows for magnified vision, such as a Fresnel lens, can be selected. The magnifying glass 20 is coupled to the frames 11 and 12 by hinges (not shown) so as to rotate about a rotation axis R2 extending in the left-right direction in FIG. 2(b). Friction acts at the joints between the frames 11 and 12 and the magnifying glass 20 so that the magnifying glass 20 can remain stationary at any rotational position.

Since one end of each of the frames 11 and 12 is connected to the coupling means 30 and the other end to the magnifying glass 20, the frames 11 and 12 move stably as one unit as the arm member 10. That is, one end 10a of the arm member 10 is rotatably coupled to the coupling means 30 about the rotation axis R1, and the magnifying glass 20 is coupled to the other end 10b of the arm member 10 so as to be rotatable about the rotation axis R2. ing. Further, the position of the magnifying glass 20 shown in FIG. 2 is the position when the magnifying glass 20 is not used, but in this state, the other end 10b of the arm member 10 is close to the lower belt 93. Further, in this state, the magnifying glass 20 as a whole is located above the rotation axis R2, and the edge 20a of the magnifying glass 20 is located below the information display body 91.

Next, the process of moving the magnifying glass 20 from the position where it is not used to the position where it is used will be explained using FIGS. 2 to 4. When magnifying glass 20 is not used, magnifying glass 20 is in the position shown in FIG. From this position, the arm member 10 is rotated counterclockwise in the figure around the rotation axis R1, and the magnifying glass 20 is rotated counterclockwise in the figure around the rotation axis R2, as shown in FIG. , the magnifying glass 20 is located in front of the information display body 91. From this state, when the arm member 10 is further rotated counterclockwise in the figure around the rotation axis R1 and the magnifying glass 20 is further rotated counterclockwise in the figure around the rotation axis R2, the magnifying glass 20 comes to the position shown in FIG.

In the state shown in FIG. 4, the magnifying glass 20 is spaced apart from the display surface 91a of the information display body 91 in the near direction, and is in a posture parallel to the display surface 91a. In this state, by looking at the display surface 91a through the magnifying glass 20, the information can be enlarged. Note that the positional relationship between the display surface 91a and the magnifying glass 20 for viewing information in an enlarged manner is not limited to the positional relationship shown in FIG. 4, and may be changed as appropriate depending on the user's viewpoint and wrist position. When the information display device 90 is worn on the wrist of the left arm, the user can view the information in a magnified view by simply moving the magnifying glass 20 from the bottom to the top with the right hand, making the operation easy. It is. Further, since the arm member 10 is sufficiently long, a sufficient distance can be secured between the magnifying glass 20 and the display surface 91a, and a sufficiently magnified view can be achieved.

When you have finished using the magnifying glass 20, from the state shown in FIG. By rotating clockwise in the figure, the magnifying glass 20 is returned to the position shown in FIG. 2. In the state shown in FIG. 2, the magnifying glass device 1 does not interfere with the movement of the user's arm. When the information display device 90 is worn on the wrist of the left arm, the user can store the magnifying glass 20 out of the way by simply moving the magnifying glass 20 from top to bottom with the right hand. Therefore, it is easy to operate.

Next, the functions of the magnifying glass device 1 when the magnifying glass 20 is not in use will be explained based on FIG. 2. As shown in FIG. 2(b), the frames 11 and 12 have a convex shape in the front direction, and when the magnifying glass 20 is not used, a part of the frames 11 and 12 is used to display information. It is located in front of the display surface 91a of the body 91. Because of this positional relationship, the chances of contacting the display surface 91a from the outside are reduced, and damage to the display surface 91a is prevented. Note that, as shown in FIG. 2(b), the frames 11 and 12 according to the present embodiment are formed and arranged so as to cover the entire information display body 91 in a side view, but at least If a portion is located in front of the display surface 91a of the information display body 91, the function of protecting the display surface 91a is exhibited.

Further, when the magnifying glass 20 is not in use, the edge 20a of the magnifying glass 20 is located below the information display body 91, as shown in FIG. The thickness of the information display body 91 is greater than the thickness of the lower belt 93. That is, in this state, the magnifying glass 20 is stored in front of the lower belt 93 and does not protrude forward from the display surface 91a of the information display body 91, so that interference with the sleeves of the user's clothes is suppressed.

It is. FIG. 6 is a schematic left side view showing a state in which a magnifying glass is used in a magnifying glass device according to a second embodiment of the present invention. The difference between this embodiment and the first embodiment described above is that the arm member 10 is divided into inner frames 13, 14 and outer frames 15, 16, and the inner frames 13, 14 and the outer frames 15, 16 are One end 10a and the other end 10b are coupled together rotatably around a rotation axis R3 at a bent portion 10c. The rotation axis R3 is parallel to the rotation axis R1 and the rotation axis R2. The inner frame 13 and the outer frame 15 are arranged on the left side of the display surface 91a, and the inner frame 14 and the outer frame 16 are arranged on the right side of the display surface 91a. The left inner frame 13 and the right inner frame 14 are connected by a horizontal member 17, thereby reinforcing the arm member 10 as a whole.

As shown in FIG. 5(b), when the magnifying glass 20 is not in use, the magnifying glass 20 is placed close to the upper belt 92, and the rotation axis R2 around which the magnifying glass 20 rotates is also located on the display surface 91a. placed higher. On the other hand, the bent portion 10c is arranged close to the lower belt 93. Therefore, the total length of the arm member 10 from one end 10a to the other end 10b is longer than that of the first embodiment described above.

When using the magnifying glass 20, the inner frames 13 and 14, the outer frames 15 and 16, and the magnifying glass 20 are rotated around the rotation axes R1, R3, and R2, respectively, so that the state shown in FIG.
