Description

[Detailed description of the invention] The present invention is an improvement of a tool box, in particular a tool box in which a lid and a sliding box are automatically expanded at the same time by expanding a pair of main rods having gripping parts. be.

Conventional tool boxes of this type, as disclosed in Utility Model Application No. 111655/1987 by the present applicant, have a grip part and an action part integrated, so that the distance from the bottom of the tool box to the top of the grip part is If the product is taller and packed in cardboard, the cardboard box itself must be made larger even though there is a blank space, which increases packaging costs, and even if it is stored in a warehouse, it takes up a lot of space. There were some extremely inconvenient points, such as the need for

The present invention was devised to eliminate these drawbacks of conventional tool boxes, and consists of dividing the main rod for deploying the tool box into a gripping part and an action part, and pivoting and connecting each part.
As shown in Figure 2, it can be rotated and bent.

Examples will be described below with reference to the drawings.

The main rod 2 is divided into a grip part 3 and an action part 4.

The gripping part 3 is made of a pipe or the like, and the end thereof is formed flat, and a substantially trapezoidal long hole 5 is bored therein.

- The operating part 4, which is rotatably pivoted to the sliding box 10 containing used clothes 12 and the box body 11, has the gripping part 3 on its upper part.
A substantially trapezoidal long hole 6 is formed by extending downwardly two sides of the long hole 5 provided at the end of the hole.

Further, a locking piece 7 is integrally bent and formed on one side edge of the upper end of the operating portion 4 .

Screws 8 are inserted into these substantially trapezoidal long holes 5 and 6.

This screw 8 is partially formed into a non-threaded portion 8a having a substantially trapezoidal cross section, which is slightly smaller in thickness than the elongated hole 5 provided at the end of the gripping portion 3, and the length of the non-threaded portion 8a is is set to be approximately equal to the thickness when the end portion of the grip portion 3 and the action portion 4 are overlapped.

The gripping portion 3 and the acting portion 4 are pivotally connected by the screw 8 and the nut 9, and constitute the main rod 2.

Furthermore, a pair of the gripping part 3 and the acting part 4 are mounted on the side surface of the tool box 1 so as to face each other.

The configuration of the present invention has been described above. Next, the operating state during use will be explained.

FIG. 4a shows a state in which the grip portion 3 and the action portion 4 are engaged with each other at a position where the tool box 1 can be deployed.

That is, the non-threaded portion 8a of the screw 8 inserted into the elongated hole 5 of the gripping part 3 is engaged with the upper part of the elongated hole 6 of the action part 4, and in this state, the gripping part 3 is expanded. When opened, the action part 4 also expands at the same time, and the lid 12 of the tool box 1 and the sliding box 10 expand at the same time.

At this time, the function of the locking piece 7 of the action part 4 is to prevent the grip part 3 from moving unsteadily when the tool box 1 is being transported.

Next, the grip part 3 is used to pack or store the tool box 1.
To bend the grip, as shown in Figure 4, first press the grip 3 from above and insert the non-threaded part 8a of the screw 8 inserted into the elongated hole of the grip 3 into the length of the action part 4. This is carried out by pushing down to approximately the center of the hole 6 and then rotating the gripping part 3 as shown in FIG. 4C.

As described above, according to the present invention, the gripping part and the acting part of the main rod can be rotated and bent with an extremely simple structure, and therefore, when packing a tool box with cardboard, etc., a small packing box is sufficient. It also has excellent practical effects, such as reducing the need for cardboard boxes, and allowing packed tool boxes to be stacked in a narrow space even when kept in stock.
