<P>PROBLEM TO BE SOLVED: To provide an attachment fitting that can be used without a connection fitting by cutting a necessary length of commercial chains and purchasing it, is not disconnected by lifting due to vibration of an earthquake or the like, and has strength, which has a simple structure facilitating attachment/removal of a chain (1), which is not disconnected by lifting due to vibration of an earthquake or the like (2), which has strength (3), and which prevents disconnection of a chain by a third party (4). <P>SOLUTION: (1) In an L-shaped plate, a 1L shape has a width of a size equal to or less than an effective length 7 of the inside of a chain. The plate thickness of a 2L shape has a size equal to or less than a width 8 of the inner side of the chain. (2) An upper part of the letter L is bent to form a side-facing flange 4 and a hole 3 is provided on an end side thereof. (3) At a corner of an inner right angle of the letter L, a dent 6 is formed which has a shape with a spike and into which the chain enters. (4) An outer right angle portion of the letter L has a width with the dent 6 of the inside, in a size equal to or less than the effective length 7 of the inside of the chain, and is round-cornered to allow passage of the chain. <P>COPYRIGHT: (C)2012,JPO&INPIT |
