However, in the technique disclosed in Patent Document 1, the number of tools that can be held in the holding device is limited to the number of holes formed in the holding device, and when adding a tool, the holding device itself. Must be newly added. Further, when the number of tools is reduced, there is a problem that holes are left and an extra space is generated.
In addition, the technique disclosed in Patent Document 2 is provided with a frame on the peripheral surface of a block assembled to increase mechanical strength, but the block constituting the frame is different from the block having a blind hole. There is a problem that the number of parts increases as the frame body is arranged and the number of parts increases, and the overall size of the holding device increases. On the other hand, if there is no frame, there is a problem that a convex part or a concave part, which is a locking means, appears on the peripheral surface of the holding device, and the safety such as these irregularities are caught when using the tool.

  The present invention has been made to solve such a problem, and the object of the present invention is to provide safety for a rod-shaped tool such as a hexagon wrench according to the necessity such as the size and number of the tool. It is an object of the present invention to provide an assembly-type tool holding device that can hold the tool in an optimum configuration while securing the tool.

In order to achieve the above-described object, the assembly type tool holding device according to claim 1 is a tool holder formed by combining a plurality of blocks, wherein one end surface and the other end surface of the block are regular polygons. No prismatic having three sides, passing from the one end surface to the other end face, the tool has a through hole for holding the form, projecting outward over the other end surface from the one end surface to the first side surface An engagement recess is formed on the second side surface from the one end surface to the other end surface, and an engagement recess is formed to engage with the engagement projection. It has at least one side surface which is a plane other than the second side surface, and each of the blocks is assembled by engaging the engaging convex portion and the engaging concave portion. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the first embodiment will be described.
1 to 3, FIG. 1 is a perspective view of a block in the first embodiment of the assembly-type tool holding device according to the present invention, FIG. 2 is a perspective view of the block in a state where a tool is held, and FIG. 3. FIG. 4A shows a top view (a) of each block and top views (b) and (c) showing examples of combinations of blocks.

A block 1 shown in FIG. 1 is a component constituting a tool holder (assembly tool device). As shown in the figure, the block 1 has a rectangular parallelepiped shape, and a through hole 6 penetrating from one end surface 2 to the other end surface 4 is formed.
The first side surface 8, which is one of the four side surfaces of the block 1, extends from the one end surface 2 to the other end surface 4 at the central position in the width direction and protrudes outward. A convex portion 10 is formed. The engaging convex portion 10 has a trapezoidal shape extending outward in a top view.

  In addition, the second side surface 12 that is one of the four side surfaces is formed with an engagement recess 14 that extends from the one end surface 2 to the other end surface 4 at the center in the width direction and that is recessed inward. Has been. The engaging recess 14 has a trapezoidal shape that expands inward in a top view. The shapes of the engaging convex portion 10 and the engaging concave portion 14 correspond to each other, and can be engaged by inserting the engaging convex portion 10 of another block 1 into the engaging concave portion 14 and sliding it in the vertical direction. is there. Since the engaging convex part 10 and the engaging concave part 14 are trapezoidal, they do not come off to the side in the engaged state.

On the other hand, among the four side surfaces, the third side surface 16 and the fourth side surface 18 other than the first side surface 8 and the second side surface 12 are flat surfaces without any irregularities.
As shown in FIG. 2, the block 1 configured as described above can hold the tool 20 by inserting a tool 20 having a rod-like portion such as a hexagon wrench into the through hole 6.

Subsequently, as shown in FIG. 3, the type of the block 1 is divided according to the diameter of the through hole 6. In the present embodiment, one through hole 6 a to 6 d having a diameter of 10 mm, 8 mm, 6 mm, or 4 mm is provided. There are five types of blocks: the blocks 1a to 1d provided, and the block 1e provided with two through holes 6e and 6f of 3 mm and 2 mm.
The tool holder is assembled by engaging the engagement convex part 10 and the engagement concave part 14 of these blocks 1a-1e.

For example, the assembly-type tool holder 22a shown in FIG. 3B uses 10 mm, 8 mm, 6 mm, and 4 mm blocks 1a to 1d one by one, and the engagement convex portion 10 of each block 1 is connected to the other block 1. It is assembled by engaging with the mating recess 14. The tool holder 22a having such a configuration can hold four different types of tools.
Further, in this case, all of the engaging convex portion 10 and the engaging concave portion 14 of each block 1 are in the engaged state, and the assembled tool holder 22 has a flat peripheral surface on the third side surface 16 of each block 1. Further, only the fourth side surface 18 is provided, and there is no unevenness on the peripheral surface of the tool holder 22.

When a block 1 is newly added, the engagement convex portion 10 and the engagement concave portion 14 are reversed by reversing the one end surface 2 and the other end surface 4 of any one of the four blocks 1a to 1d. By changing the direction, the engaging convex portion 10 may be positioned on the peripheral surface of the tool holder 22 and the engaging concave portion 14 of the new block 1 may be engaged with the engaging convex portion 10.
As another example of combination, the tool holder 22b in FIG. 3 (c) has a block 1a having a through-hole 6 diameter of 10 mm, a block 1b of 8 mm, a block 1d of 4 mm, a block 1d of 3 mm and a block 1e of 2 mm. , Two 6 mm blocks 1 c are formed from a total of six blocks 1. Specifically, the tool holder 22b is composed of a 3mm and 2mm block 1e, a 4mm block 1d, a 6mm block 1c, a first 8mm block 1b, a 10mm block 1a, and a second 8mm block 1b, respectively. The engaging projection 10 is engaged with the mating engaging recess 14. The tool holder 22b having such a configuration can hold seven tools.

Further, in the case of the tool holder 22b having the combination shown in FIG. 3C, a new block can be added to the 3 mm and 2 mm blocks 1e or the second 8 mm block 1b from this state.
As described above, the tool holder 22 according to the present embodiment combines the blocks 1 each having the engagement convex portion 10 and the engagement concave portion 14 to meet the needs of the type, number, arrangement, and the like of the tools. An optimally configured tool holding device can be freely formed.

  Further, the engaging convex portion 10 and the engaging concave portion 14 extend from one end surface 2 of the block 1 to the other end surface 4, and the through hole 6 for holding the tool also penetrates from the one end surface 2 to the other end surface 4. Therefore, when the blocks 1 are combined, the direction of the engagement convex portion 10 and the engagement concave portion 14 can be easily changed by reversing the one end surface 2 and the other end surface 4 so as to be interchanged. Thereby, even if it is the block 1 of the said 1st Embodiment where the 3rd side surface 16 and the 4th side surface 18 are planes, the tool holder 22 of various combinations can be comprised. And the unevenness | corrugation of the surrounding surface of the tool holder after an assembly can be suppressed to the minimum because the 3rd side surface and the 4th side surface of the said block 1 are planes. As a result, the tool holder 22 has a minimum configuration without providing a frame or the like on the peripheral surface, and thus can have a shape that ensures safety without being caught during operation.
