## Background
BACKGROUND OF THE INVENTION
The present invention relates to a toolbox and, more particularly, to a toolbox permitting easy access to tools received in the toolbox and occupying a smaller space.
A type of toolbox generally includes a box body for receiving tools and a top cover directly covering an upper opening of the box body. An end of the top cover is pivotably connected to the box body. A cover body of the top cover prevents the tools from falling out of the box body. When a user is intended to use the tools, the user opens the top cover, takes the tools out, and closes the top cover, which is inconvenient. Furthermore, the toolbox of this type cannot be used in a limited space, because a larger space is occupied when the top cover is opened. The operational inconvenience of occupying a larger space due to opening of the top cover is worse when the toolbox is of a portable type.
U.S. Pat. No. 8,016,108 discloses a tool box including a top cover for covering a housing. The top cover is pivotably connected to the housing by a rotation shaft having a drive gear. A torsion spring is received in the rotation shaft. The housing includes a receiving seat for receiving tool tips. The housing includes a driven gear meshed with the drive gear of the top cover. Thus, when the top cover is opened, the receiving seat is automatically exposed to permit access to the tool tips. Although the receiving seat can be exposed while the top cover is opened, the user still has to open the top cover that will occupy a larger space. As a result, the tool box is still not suitable for a limited space.
BRIEF SUMMARY OF THE INVENTION
An objective of the present invention is to provide a toolbox that can be pressed to permit access to tools received therein, providing operational convenience and occupying a smaller space.
A toolbox according to the present invention includes a receiving seat having two sidewalls, an upper wall, and a lower wall spaced from the upper wall in a vertical direction.

Each of two sides of the pivotal seat 2 includes an axle 22 insertable into the first guiding groove 15 of one of the sidewalls 11 of the receiving seat 1. The opening 153 of each first guiding groove 15 permits one of the axles 22 of the receiving seat 2 to be easily inserted into one of the first guiding grooves 15. Each side of the pivotal seat 2 further includes a groove 23 having an opening 231 in a bottom end of the groove 23. Each pivot 16 of the receiving seat 1 is received in one of the grooves 23 of the pivotal seat 2. Each groove 23 of the pivotal seat 2 includes a top end having a pivot coupling portion 232 for coupling with one of the pivots 16.
The pressing seat 3 is mounted to an outer side of the receiving seat 1 and is movable relative to the receiving seat 1 in the vertical direction. The pressing seat 3 includes two vertical portions 31 respectively mounted to outer sides of the two sidewalls 11 of the receiving seat 1. The pressing seat 3 further includes a top portion 32 connected between upper ends of the two vertical portions 31. Each vertical portion 31 includes a second guiding groove 33 extending in a transverse direction perpendicular to the vertical direction and having a wall face 331. Each axle 22 of the pivotal seat 2 is received in the second guiding groove 33 of one of the two vertical portions 31 of the pressing seat 3.
The pressing seat 3 further includes a guiding portion 34 below each second guiding groove 33 to permit easy assembly. Each guiding portion 34 includes a recessed portion 341 receiving an end of one of the axles 22 of the pivotal seat 2. Each guiding portion 34 further includes a partitioning protrusion 342 formed between a top end of the recessed portion 341 and the second guiding groove 33 above the guiding portion 34. Each vertical portion 31 of the pressing seat 3 further includes a rail 35 slideably received in one of the vertical grooves 17 of the receiving seat 1.
The top portion 32 of the pressing seat 3 includes a front wall 321, a rear wall 322, and a top wall 323. The front wall 321, the rear wall 322, and the top wall 323 define a second receiving space 324. The top wall 323 includes a positioning groove 36 for releasably engaging with the positioning plate 18 of the receiving seat 1. The positioning groove 36 of the pressing seat 3 is defined in the top wall 323 and an upper end of the front wall 321 of the pressing seat 3. The front wall 321 includes an inner face having a second slant guiding face 325. The top wall 321 further includes an inner face having a second attachment portion 326.
An elastic element 4 is mounted between the receiving seat 1 and the pressing seat 3 for returning the pressing seat 3. In the form shown, the elastic element 4 is a compression spring and has two ends respectively attached to the first attachment portion 121 and the second attachment portion 326.
In assembly, the axles 22 of the pivotal seat 2 are inserted via the openings 153 into the first guiding grooves 15 of the receiving seat 1. An end of the elastic element 4 is attached to the first attachment portion 121 of the upper wall 12 of the receiving seat 1. Then, the pressing seat 3 is mounted on top of the receiving seat 1, with the recessed portions 341 of the guiding portions 34 of the pressing seat 3 aligned with the axles 22. Next, the second guiding grooves 33 of the pressing seat 3 engage with the axles 22 of the pivotal seat 2 by using the flexibility of the vertical portions 31, with the other end of elastic element 4 attached to the second attachment portion 326 and with the elastic element 4 biasing the pressing member 3 to an unpressed position. The openings 231 of the grooves 23 of the pivotal seat 2 are aligned with the pivots 16 of the receiving seat 1. The receiving seat 2 is in a storage position in which the tool receiving portion 21 receiving the tools 5 is in the first receiving space 14 of the receiving seat 1. Furthermore, the coupling holes 211 are in the vertical direction to avoid falling of the tools 5.
With reference to FIG. 5, if a user is intended to use the tools 5, the user presses the pressing seat 3. The wall face 331 of each second guiding groove 33 of the pressing seat 3 presses against one of the axles 22 of the pivotal seat 2 to move the axle 22 downward along the upper, vertical, rectilinear section 151 of one of the first guiding grooves 15. Furthermore, the pivot coupling portions 232 of the pivotal seat 2 press against the pivots 16 of the receiving seat 1. The rails 35 of the pressing seat 3 move downward along the vertical grooves 17 of the receiving seat 1 to provide stable movement.
When the pressing seat 3 is further pressed, the axles 22 move along the arcuate sections 152 of the first guiding grooves 15 and pivot, such that the pivot seat 2 pivots about a pivot axis defined by the pivots 16 of the receiving seat 1. Thus, the pivotal seat 2 pivots to an exposed position permitting access to the tools 5. When the pivotal seat 2 pivots, the second guiding grooves 33 extending in the transverse direction permit the axles 22 to move in the transverse direction relative to the pressing seat 3. Thus, the tools 5 can be accessed when the pivotal seat 2 has pivoted through an angle smaller than 90°, as shown in FIG. 5.
With reference to FIGS. 6 and 7, when the axles 22 of the pivotal seat 2 are moved to a position below the arcuate sections 152 of the first guiding grooves 15 by pressing the pressing seat 3 downward, the pivotal seat 2 pivots 90°, and the first slant guiding face 191 of the engagement member 19 presses against the second slant guiding face 325 of the pressing seat 3 such that engagement member 19 extends through the positioning groove 36. The engagement edge 192 engages with and is positioned at an edge of the positioning groove 36. Then, the pressing seat 3 is released, and the pivotal seat 2 retains in the exposed position permitting access to the tools 5.
With reference to FIG. 8, if it is desired to close the toolbox, the positioning plate 18 extending beyond the positioning seat 36 can be pressed to disengage the engagement member 19 from the positioning groove 36. The pressing seat 3 is moved upward by the elastic force of the elastic element 4, and the axles 22 of the pivotal seat 2 move upward along the first guiding grooves 15, causing the tool receiving portion 21 and the tools 5 to move into the first receiving space 14 of the receiving seat 1. Thus, the toolbox according to the present invention is easier to operate and occupies a smaller space.
In view of the foregoing, the toolbox according to the present invention is easy to operate and solves the disadvantage of occupation of a larger space of conventional toolboxes. It can be appreciated that the pivotal seat 2 can be fixed in a position other than the 90° position. Furthermore, the pivotal seat 2 can include different tool receiving portions 21 for receiving various tools 5.
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
