Toolbox
A toolbox, which includes a box body, a number of tool bit holders pivotally mounted inside the box body and linked to one another by links, and a top cover pivoted to the box body with two flat pivot bolts for forcing the tool bit holders from a horizontal position to a tilted position when it is opened from the box body.
1. Field of the Invention:
The present invention relates to toolboxes and more particularly, to a durable and inexpensive toolbox.
2. Description of the Related Art:
This design of toolbox has drawbacks as follows:
-
- 1. The use of the links 4 complicated the structure of the toolbox.
- 2. When opened the top cover 2, the top cover 2 and the tool bit holder 10 are held in position by means of forcing the raised portions 16 of the pivot bolt 15 against the deformable portions 13 of the tool bit holder 10. However, the thin deformable portions 13 tend to break during the use of the toolbox.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a toolbox, which has a simple structure. It is another object of the present invention to provide a toolbox, which is durable in use. To achieve these and other objects of the present invention, the toolbox comprises a box body, the box body comprising two pivot holes aligned at two opposite lateral sides thereof near one end, and engagement teeth bilaterally formed in each of the two coupling holes of the box body; a top cover, the top cover comprising two mounting lugs respectively downwardly extending from two opposite lateral sidewalls thereof near one end, the mounting lugs each having an elongated coupling hole and a side notch; a first tool bit holder, the first tool bit holder comprising two opposite sidewalls, two dual sector-like coupling holes symmetrically disposed at the two opposite sidewalls, and two side pins respectively perpendicularly extending from the two opposite sidewalls corresponding to the side notches of the mounting lugs of the top cover; a plurality of second tool bit holders respectively pivotally mounted inside the box body; a plurality of links respectively coupled to the first tool bit holder and the second tool bit holders; and two flat pivot bolts respectively mounted in the coupling holes of the mounting lugs of the top cover, the coupling holes of the box body and the dual sector-like coupling holes of the first tool bit holder to pivotally secure the top cover and the first tool bit holder to the box body, the flat pivot bolts each having engagement teeth symmetrically disposed at two opposite sides.
When opening the top cover from the box body, the side notches of the mounting lugs of the top cover are forced into engagement with the side pins of the first tool bit holder to further force the first tool bit holder to a tilted position relative to the box body, and at the same time the links are forced to turn the second tool bit holders to a tilted position and the flat pivot bolts are turned with the top cover to force the engagement teeth thereof into engagement with the engagement teeth in the coupling holes of the box body to stop the first and second tool bit holders in the tilted position.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to FIGS. 2˜6, a toolbox in accordance with the present invention is shown comprised a box body 20, a top cover 30, a first tool bit holders 23, a plurality of second tool bit holders 24, and two pivot bolts 26.
The box body 20 comprises two coupling holes 21 aligned at two opposite lateral sides near one end, and engagement teeth 22 bilaterally formed in each of the two coupling holes 21.
The top cover 30 comprises two mounting lugs 31 respectively downwardly extending from two opposite lateral sidewalls thereof near one end. The mounting lugs 31 each have an elongated coupling hole 32 and a side notch 33.
The first tool bit holder 23 comprises two dual sector-like coupling holes 25 symmetrically disposed at two sides, and two side pins 230 respectively perpendicularly extending from the two opposite sidewalls. The second tool bit holders 24 each have two pivot rods 240 respectively pivoted to the two opposite sidewalls of the box body 20.
The pivot bolts 26 are flat bolts, each having engagement teeth 27 symmetrically disposed at two opposite sides.
The two pivot bolts 26 are respectively mounted in the coupling holes 32 of the mounting lugs 31 of the top cover 30, the coupling holes 21 of the box body 20 and the dual sector-like coupling holes 25 of the first tool bit holder 23 to pivotally secure the top cover 30 and the first tool bit holder 23 to the box body 20. Further, links 241 are respectively coupled to the tool bit holders 23 and 24 to join the tool bit holders 23 and 24.
