 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

Referring to FIG. 1, the first preferred embodiment of a toolbox 100 according to the present invention is shown to include first and second toolbox parts 3, 4, and a pivot joint unit 6.

The toolbox 100 of this embodiment serves to hold first and second sets of tools 200, 300 (see FIG. 5) in a manner that will be described hereinafter.

It is noted that each of the tools 200, 300 in the first and second sets is an Allen wrench and has a distinct size.

The first toolbox part 3 includes a base wall 31, a front wall 32, and a pair of lateral walls 33, 34. The base wall 31, the front wall 32, and the lateral walls 33, 34 of the first toolbox part 3 cooperatively define an accommodating space 30 thereamong. The first toolbox part 3 has an opening 301 that is in spatial communication with the accommodating space 30 in the first toolbox part 3.

The second toolbox part 4 includes a base wall 41, a front wall 42, and a pair of lateral walls 43, 44. The base wall 41, the front wall 42, and the lateral walls 43, 44 of the second toolbox part 4 cooperatively define an accommodating space 40 thereamong. The second toolbox part 4 has an opening 401 that is in spatial communication with the accommodating space 40 in the second toolbox part 4.

The toolbox 100 further includes first and second ears 51, 52, each of which extends from a respective one of opposite ends of the front wall 32 of the first toolbox part 3, and third and fourth ears 53, 54, each of which extends from a respective one of opposite ends of the front wall 42 of the second toolbox part 4.

The pivot joint unit 6 includes first and second pivot joints 61, 62. The first pivot joint 61 of the pivot joint unit 6 is disposed between the first and second ears 51, 52, and is coupled rotatably to the first and second ears 51, 52. On the other hand, the second pivot joint 62 of the pivot joint unit 6 is disposed between the third and fourth ears 53, 54, extends parallel and is coupled to the first pivot joint 61, and is coupled rotatably to the third and fourth ears 53, 54. The construction as such permits relative rotation between the first and second toolbox parts 3, 4 about the first and second pivot joints 61, 62 of the pivot joint unit 6 between a closed position, where the first and second toolbox parts 3, 4 overlap with each other such that the first toolbox part 3 covers the opening 401 in the second toolbox part 4 and such that the second toolbox part 4 covers the opening 301 in the first toolbox part 3, as best shown in FIG. 2, and an open position, where the first and second toolbox parts 3, 4 overlap with each other such that the first toolbox part 3 uncovers the opening 401 in the second toolbox part 4 and such that the second toolbox part 4 uncovers the opening 301 in the first toolbox part 3, as best shown in FIG. 3. The toolbox 100 of this invention therefore occupies the same space regardless of whether the first and second toolbox parts 3, 4 are disposed at the closed or open position.

With further reference to FIG. 4, the pivot joint unit 6 further includes a third pivot joint 63 that extends transversely relative to the first and second pivot joints 61, 62 and that is rotatably coupled to an engaging groove 620 in the second pivot joint 62. The construction as such permits relative rotation between the first and second toolbox parts 3, 4 about the third pivot joint 63 between a first position, where the opening 301 in the first toolbox part 3 and the opening 401 in the second toolbox part 4 face in the same direction, as best shown in FIG. 5, and a second position, where the opening 301 in the first toolbox part 3 and the opening 401 in the second toolbox part 4 face in opposite directions, as best shown in FIG. 6. The toolbox 100 further includes a first pair of abutting protrusions 71, 72, each of which is provided on a respective one of opposite end portions of the first pivot joint 61 of the pivot joint unit 6, and a second pair of abutting protrusions 73, 74, each of which is provided on a respective one of opposite end portions of the second pivot joint 62 of the pivot joint unit 6. The abutting protrusions 71, 72 abut against the front wall 32 of the first toolbox part 3 and the abutting protrusions 73, 74 abut against the front wall 42 of the second toolbox part 3 when the first and second toolbox parts 3, 4 are disposed at one of the closed and open positions. As such, it is ensured that the first and second toolbox parts 3, 4 wholly overlap each other when disposed at the closed or open position. In an alternative embodiment, the toolbox 100 maybe dispensed with the first and second pairs of abutting protrusions 71, 72, 73, 74.

The toolbox 100 further includes first and second tool retainer units 8, 9. The first retainer unit 8 is disposed in the accommodating space 30 in the first toolbox part 3, is provided on the first toolbox part 3, and retains the first set of tools 200 in the accommodating space 30 in the first toolbox part 3.
