Claims

[Claims for Utility Model Registration] The magnifying glass frame is made of a long and thin sheet plate M made of synthetic resin, and the sheet plate M is formed with a first transverse fold at a constant interval W1 corresponding to the folding height approximately at the center of the frame. The grooves 11 and the second horizontal bending grooves 12 are arranged in parallel, and while maintaining the distance W2 which is almost the same as the distance W1 with respect to the rear end edge of the sheet plate M in the longitudinal direction, A first half of the frame is provided with a third horizontal bending groove 14 parallel to the bending grooves 11 and 12, and is partitioned between the front end edge of the sheet plate M in the longitudinal direction and the first horizontal bending groove 11. Part A and second and third horizontal bending grooves 12 and 14
The rear half B of the frame divided between the frames is defined to be substantially the same in size and almost symmetrical in terms of the contour shape, and the lens surrounding frame 15 is erected in the front half A of the frame. While the lens 16 is fitted and fixed within the frame, a first vertical bending groove 19 and a second vertical bending groove 19 are formed in the rear half B of the frame at a constant interval W3 approximately in the center of the sheet plate M. The bending grooves 20 are arranged parallel to each other, and a pair of corresponding wing pieces 21 and 23 are provided upright from both left and right edges in the width direction of the sheet board M, and the sheet board M is Both horizontal bending grooves 11
, 12 at right angles, the front half A of the frame and the rear half B of the frame overlap, and the front and rear edges of the sheet M can be releasably engaged. It is in a half-folded state, and the sheet plate M is also folded into the first and second vertical bending grooves 1.
When bent at right angles from 9, 20, the pair of left and right wing pieces 21, 2 in the rear half B of the frame.
3 overlap and are detachably engaged with each other so that the rear half B of the frame is three-dimensionalized as a square frame-shaped handle.
