Abstract: Disclosed is a display structure in which an insertion opening, slide grooves, a first fitting portion and a ridged portion along which the display plate bends when the display plate is bent arranged in the loading sections of a support body in a suitable manner to ensure that when the display plate is inserted into or removed from the loading unit, a force is exerted on both sides of the display plate in either the direction from the display surface side to the rear surface side thereof or the direction from the rear surface side to the display surface side thereof, and a force is exerted in another direction at the center region of the display plate. As a result of configuring in this manner, the display plate deforms so that the entire display surface side comes to have a convex or concave shape, thereby allowing the display plate to be attached to or detached from the support body without forcible localized deformation of the display plate.

Abstract: A locking device comprising: a lock body; a plurality of dial rings; and a fixing member which is elongated in shape and is locked by being directly fixed with the plurality of dial rings, wherein said fixing member includes a convex-concave part with repeated concaves and convexes formed in the longitudinal direction of said fixing member, each of said dial rings includes a cutout which is provided on a part of the circumferential direction in such a manner that allows said fixing member to be freely inserted/withdrawn at a rotation position which is the unlocking position and that one of said dial ring abuts the convexes of the concave-convex part at a rotation position except for the unlocking position, said locking device includes a passage for inserting/withdrawing said fixing member, a part of the passage is a hole which reaches said dial rings from outside said locking device, and the hole is curved or flexed such that said dial rings are invisible from outside said locking device via the hole, and thu

Abstract: A locking method for preventing an umbrella from opening by a locking device and a large diameter part forming member, wherein the locking device includes a fixing member and a lock body, the large diameter part forming member is a member for forming one or more large diameter part when the umbrella to be locked is closed, said locking method comprises: creating a part in which a cross-sectional outside diameter vertical to a shaft direction of the umbrella tube is narrower than outside diameters of an upper part and a lower part by placing the large diameter part forming member on the umbrella tube or a part of the rib between the runner and the ferrule or contacting a stretcher before closing the umbrella and by closing the umbrella, placing the part of the umbrella where the cross-sectional outside diameter vertical to the shaft direction of the umbrella tube is narrower than the outside diameters of the upper part and the lower part, in a loop formed with the fixing member and the lock body; and preventin

Abstract: A fastening method for fastening an object by crossing two or more fasteners each of which includes a connecting hole or a connecting groove, and by tightening the fasteners at the same time by fastening each of the fasteners after the other fastener is connected to the connecting hole or a connecting groove or the other fastener. With this, the fasteners are not piled, and less likely to be loose. Thus the fasteners are less likely to be fall off even when any fastener is loose, and the fasteners can be easily fastened again. In addition, a linear object such as wires can be easily fastened, and it is possible to fasten a spherical object when three or more fasteners are used. By using a band-type locking device as a fastener, books and files can also be easily locked.
