<p><P>PROBLEM TO BE SOLVED: To easily lock a bag even when the bag is packed with such many articles as to hardly close a lid. <P>SOLUTION: A lock device for a bag includes: a linking hook C which is attached to the lid of the bag and has a first linkage piece 20c where a lower tapered surface 21c with an acute angleαwith respect to a vertical line and an upper tapered surface 22c with an obtuse angleβwith respect to the vertical line are formed at the end of the linking hook C; and a linkage member 2 having a second linkage piece 20 which is linked with the linking hook C and where an upper tapered surface 21 with an acute angleαwith respect to the vertical line and a lower tapered surface 22 with an obtuse angleβwith respect to the vertical line are formed at the end, wherein the linkage member 2 is held at a neutral position by a pair of opposing coil springs 122, 132. In the lock device, when the linkage member 2 is in the neutral state, the tapered surface 21 with the acute angleαin the first linkage piece 20c slides the tapered surface 21 with the acute angleαin the second linkage piece 20, and the linkage member 2 is moved against the elastic force of the coil springs, whereby parts close to the ends of both linkage pieces 20c, 20 are linked, so that the bag is temporarily fastened. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
