Hereinafter, the specific structure of the present invention will be explained based on the illustrated embodiment. In FIGS. 1 to 5, which show the disassembled state and assembled use state of the magnifying glass, 1 is a ring-shaped metal member that holds a lens 2. The holding frame is pre-formed with split grooves 3, and a pair of separated left and right screw protrusions 4 are matched with each other, and a mounting shaft 5 of a certain length is screwed into this. By tightening, the lens 2 can be fixed within the holding frame 1 and can be replaced. 6 is a screw hole carved in the center of the mounting shaft 5. however,
As long as the mounting shaft 5 is projected from a part of the peripheral edge of the annular holding frame 1, the annular lens holding frame 1 and the mounting shaft 5 of the handle, which will be described later, are made of, for example, hard synthetic resin in advance. It may be integrally molded.

The mounting shaft 5 has a round bar shape with a diameter substantially equal to the band width W of the lens holding frame 1, and a pin receiving hole 7 is formed on the diameter line of the mounting shaft 5, passing through it in the vertical direction (in the direction in which the lens is directly viewed). It is opened. In the illustrated example, this pin receiving hole 7 is provided as one penetrating hole, but it is also possible to make a pair of upper and lower pin receiving holes and drill them separately into the mounting shaft 5.

Further, 8 can hold the lens holding frame 1 from the band width direction (lateral direction), and the holding frame 1
It is an elongated U-shaped handle when viewed from the side and has a length that can cross the handle, and its bent base end is used as a spring fulcrum 9, and a pair of opposing upper and lower detachable tips act to expand each other. Reference numeral 10 denotes a reinforcing rib at the bent proximal end of the handle 8, which applies an appropriate spring pressure to the middle end of the handle 8. As is clear from FIG. 5, the pair of upper and lower tips are curved as concave arcuate surfaces that can come into close contact with the circular surface (convex curved surface) of the mounting shaft 5, thereby stably holding the mounting shaft 5. It is designed to function as a holding piece 11. Reference numeral 12 denotes pivot pins that are respectively protruded inward from the center of the arcuate concave tip holding pieces 11 so as to face each other, and these pins are inserted into the pin receiving hole 7 of the mounting shaft 5. By being inserted from above and below, the handle 8 is aligned with the mounting shaft 5.
It is assembled in.

Therefore, in the assembled state shown in FIGS. 2 to 5, the magnifying glass can be used by grasping the handle 8. In that case, the tip holding pieces 11 of the handle 8 are in a normal state under spring pressure in the direction of mutual contraction,
In addition, its concave arc surface closely aligns with the convex arc surface of the mounting shaft 5, so the handle 8 does not swing sideways around its pivot pin 12, so it can be held and used with extreme stability. You will be able to do that. Furthermore, when inserting the pivot pin 12 of the holding piece 11 into the pin receiving hole 7 of the mounting shaft 5, the tip of the handle 8 is expanded while resisting the spring biasing force exerted by its contraction. Because of this,
In the assembled state of the handle 8 due to the insertion, there is no fear that the handle 8 will separate from the mounting shaft 5.
In the illustrated example, the mounting shaft 5 has a cylindrical shape as a whole, but opposing parts of its surfaces are formed into a pair of upper and lower arcuate convex curved surfaces so as to closely match the arcuate concave curved surfaces of the holding piece 11. In the illustrated example, only the tip of the handle 8 is attached to the holding piece 1 having a concave arc shape.
Although the handle 8 is curved as shown in FIG. 1, the entire handle 8 may be curved in an arc shape. Further, in the illustrated example, the handle 8 itself is made of a spring steel plate, but the handle 8 may be made of a non-metallic material as long as it has the above-mentioned springiness.

Next, when folding the magnifying glass configured as described above, the handle 8 is horizontally rotated around the assembly pivot pin 12 with respect to the mounting shaft 5, and the handle 8 is rotated horizontally as shown in FIG. 8 and then as shown in FIG. 6. It is sufficient to change it to a planar form. In this process, as shown in FIGS. 9 and 10, the concave arc-shaped holding piece 11 of the handle 8 automatically rides on the convex arc surface of the mounting shaft 5, resisting the spring pressure. As a result, the lens holding frame 1 is moved to a state where the lens holding frame 1 is sandwiched between them without any trouble in the expanded state, and eventually reaches a small and compact folded state where it traverses the center line of the holding frame 1. Become. In other words, the handle 8 is horizontally rotated by 180 degrees.

The final state of the above-mentioned folding is also shown in Fig. 7, and when the handle 8 is horizontally rotated 180 degrees in this way, the handle 8 is When the concave arc-shaped holding piece 11 is under pressure from the contraction spring, it comes into close contact with the convex arc surface of the mounting shaft 5, so that the folding and use states are automatically positioned during the rotation operation. At the same time, it is fixed and maintained in a stable state without wobbling or improper rotation. It goes without saying that the magnifying glass can be restored to its used condition by horizontally rotating it back to the plan view shown in FIG. 2 through the intermediate steps from FIG. 6 to FIG. 8. In the folded state, the handle 8 crosses the lens holding frame 1, so the lens 2 can be safely protected. It is also conceivable to extend it into a large diameter circle that can be shielded. Similarly, in the folded state, the bent proximal end of the handle 8 may be intentionally releasably locked to a corresponding portion of the peripheral edge of the lens holding frame 1.

As described above, in the present invention, the lens holding frame 1 has the mounting shaft 5 of a certain length protruding from a part of the annular periphery.
and a U-shaped handle 8 that is long enough to cross the holding frame 1 while holding it therebetween, and is provided with a spring biasing force that constantly contracts from the upper and lower pair of opposing distal end portions of the handle 8. By assembling both tips in a pivotal manner to the mounting shaft 5 of the lens holding frame 1, and horizontally rotating the handle 8 by 180 degrees around the pivot point,
In a magnifying glass whose handle 8 is foldable in a transverse state to the lens holding frame 1, the surface of the mounting shaft 5 has at least a pair of upper and lower arcuate convex curved surfaces facing each other, and an opening at the center of the arcuate convex curved surfaces. While providing a pin receiving hole 7, both ends of the handle 8 are curved as a holding piece 11 of a concave arc shape that closely aligns with both arc convex curved surfaces of the mounting shaft 5 when the handle 8 is gripped and used and when folded. , and the pivot pins 12 corresponding to the pin receiving holes 7 are made to protrude inwardly from the centers of the both holding pieces 11, and the pivot pins 12 are applied to the spring biasing force of the handle 8 which acts on the contraction. By inserting the handle 8 into the pin receiving hole 7 while resisting, the handle 8 and the mounting shaft 5 of the lens holding frame 1 are irremovably assembled, and the handle 8 is rotated 180 degrees around the pivot pin 12. In the process of horizontally rotating the handle 8, the concave arc-shaped holding piece 11 automatically rides on the convex arc surface of the mounting shaft 5, and the handle 8 is forcibly expanded. Therefore, although the magnifying glass has excellent operability in converting between the gripped and used state of the handle 8 and the folded state of the handle 8, it has the effect of being able to fix and lock both states extremely stably.
