Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a storage device and, more particularly, to a tool box for storing hand tools.

2. Description of the Related Art

A conventional tool box was disclosed in the U.S. Pat. No. 5,577,779, and comprises a first component 12 which is releasably joined to a second component 16 using a snap fit lock mechanism. A resilient locking arm 10 is integrally molded to first component 12. A pair of support ribs 18 are located between locking arm 10 and first component 12. Locking arm 10 includes a projection 20 integrally molded to the front side of the locking arm. Projection 20 defines a step portion 22. Projection 20 includes a cam surface 21 located between step 22 and the distal end of locking arm 10. A locking frame 14 is integrally molded to second component 16. Locking frame 14 contains a pair of parallel, spaced apart side supports 24, and a crossmember 26 which is attached to the distal end of each side support 24. A resilient tab 28 is integrally molded to second component 16. The snap fit lock mechanism has a released position, shown in FIGS. 1 and 2, and a locked position, shown in FIGS. 5 and 6. In the released position, first component 12 and second component 16 are separated and the lock mechanism is not engaged. In the locked position, first component 12 is joined to second component 16 and the lock mechanism is engaged. When the locking arm 10 is received in the side support 24, the locking arm 10 presses the resilient tab 28, such that the step 22 and the crossmember 26 are locked, and the first component 12 and the second component 16 are interlocked. When the cam surface 21 is pressed, the locking arm 10 is moved to press the resilient tab 28, such that the step 22 is detached from the crossmember 26, and the locking arm 10 is removed from the side support 24, thereby opening the first component 12 and the second component 16. The conventional tool box has the following disadvantage. When the user wishes to detach the step 22 from the crossmember 26, the cam surface 21 is pressed to drive the locking arm 10 to press the resilient tab 28, and the locking arm 10 is moved with support of the support ribs 18. However, the locking arm 10 and the first component 12 are formed integrally, and the resilient tab 28 and the second component 16 are formed integrally, such that the support ribs 18 at the connection of the locking arm 10 and the first component 12 are easily worn out or broken due to frequent actions during a long-term utilization. In addition, the connection of the resilient tab 28 and the second component 16 is also easily worn out or broken due to frequent actions during a long-term utilization.
