Title:
STRUCTURE FOR LOCKING AND UNLOCKING LID TO AND FROM STORAGE CASE
Document Type and Number:
Japanese Patent JP3123935
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To prevent a lid removably fitted in an opening in the bottomed cylinder of a storage case from dropping unexpectedly by surely regulating the movement of the lid relative to the opening and to allow the lid to be easily attached to and removed from the opening.
SOLUTION: A lid 3 removably fitted into an opening 2 in a cylinder 1 is included. A pair of locking holes 4 are provided at the opening edge 2a, and a locking plate part 7 having a pair of locking projections 8 is provided at the lid edge 3a. The locking plate part 7 is supported on both flexible arms 6 of the lid edge 3a and can assume a lock position P where both of the locking projections 8 are locked into the locking holes 4 at the opening edge 2a and an unlock position where the locking projections 8 are removed from the locking holes 4. The locking plate part 7 is given flexibility so that the interval L between the locking projections 8 can be changed into a state in which they can be locked and into a state in which they can be fitted into and removed from the locking holes 4 at the opening edge 2a, in order for the locking projections 8 to be fitted into and removed from the locking holes 4 at the opening edge 2a when the flexible arms 6 are bent so that the locking plate part 7 can take the lock position P and the unlock position. Further, a locking hole 5 is provided at the opening edge 2a, a locking projection 10 is provided at the lid edge 3a, and the locking hole 5 and the locking projection 10 are designed so that they can be fitted together. Thereby the lid 3 is prevented from dropping. It is made easier to attach and remove the lid 3.
