Description

Technical Field

[0001] The present invention relates to a part remover for disassembling an assembly block that can sequentially connect block plates via joints to assemble a three-dimensional work.

Background Art

[0002] Based on the invention described in Patent Document 1 below, the applicant provides a plastic assembly block [product name: LaQ (registered trademark)] composed of a combination of block plates 11 having a square or equilateral triangular planar shape and joints 21 for connecting these block plates 11 to each other, and such assembly blocks are widely distributed. The currently distributed assembly blocks are small ones with each side of the block plate 11 being about 17 mm.

[0003] In addition to such small assembly blocks, the applicant has newly planned a large assembly block with each side of the block plate 11 being about 64 mm. As the block plate 11 which is its basic part, a square-shaped one shown in Fig. 7(a) (see Patent Document 2), an equilateral triangular-shaped one shown in Fig. 7(b) (see Patent Document 3), and as the joint 21, a joint having the shape shown in Fig. 7(c) (see Patent Document 4) are considered.

[0004] On each side around the periphery of this block plate 11, a receiving port 12 with the front and back surfaces recessed is formed, and in the receiving port 12, an arc-edge concave portion 13a and a circular concave portion 13b with the back side recessed are provided.

[0005] In the joint 21, plugs 22 with tongue pieces facing each other project at least in two directions, and on the inner surface of the plug 22, an arc-edge convex portion 23a and a circular convex portion 23b with the end side bulging are provided. Further, from the base of the plug 22, prismatic side extensions 24 project toward both sides, and in the side extensions 24, deep angular holes 25 opening at the end faces are formed.

[0006] When connecting these block plates 11 together, if the plug 22 of the joint 21 is fitted into the receiving opening 12 of the block plate 11, the outer edge of the plug 22 abuts against the step on the far side of the receiving opening 12, the curved edge recess 13a and the curved edge protrusion 23a engage, the circular recess 13b and the circular protrusion 23b engage, and the side extension 24 abuts against the outer surface of the block plate 11, stabilizing the connection.

[0007] There are several types of joints 21 depending on the connection method. In addition to the basic type shown in the figure, in which the plug 22 protrudes in two directions on the same plane, there are also types in which the plug 22 protrudes in two orthogonal directions, three orthogonal directions, two directions at a 120° angle, and types with a large distance between the base ends of the plug 22.

[0008] Furthermore, as special parts of the assembly block, as shown in Figure 8, there are also joints 21 from which shafts 26 are extended, and wheel members 31 that are inserted into and attached to the shafts 26. By combining these parts, it is possible to assemble an automobile in which shafts 26 protrude from the four corners of a vehicle body having an inclined surface at the front of a cubic interconnected body, and wheel members 31 are attached to each shaft 26.

[0010] By the way, in the large assembly blocks described above, separating the connected block plates 11 and joints 21 requires bending them by twisting them using one end of the contact area as a fulcrum, which requires a relatively large force. In addition, the cubic connected structure presents the problem of being difficult to dismantle.

[0011] Therefore, the objective of this invention is to enable the connected parts of an assembly block to be easily separated, and to allow the parts to be easily rearranged multiple times. [Means for solving the problem]

[0012] To solve the above-mentioned problems, this invention comprises a combination of a block plate having a receiving opening around its periphery and a joint having a plurality of plugs that are inserted into the receiving opening and protruding in different directions, the joint being applied to an assembly block having deep rectangular holes opening at the end faces in rectangular tubular side extensions extending from the base end of the plugs on both sides, and is a parts remover for separating joined parts. The overall shape is rod-shaped, and each end of the gripping portion has an insertion portion that engages with a rectangular hole in the side extension of the joint, and of the insertion portions, one insertion portion and the other insertion portion have different shapes. The aforementioned insertion portion is shaped like a square prism, corresponding to the case where the rectangular hole in the side extension of the joint has a square cross-sectional shape. The other insertion portion is provided as a flattened rectangular prism shape that is wider than the first insertion portion, corresponding to cases where the rectangular hole in the side extension of the joint has a rectangular or trapezoidal cross-sectional shape.

[0013] Furthermore, the gripping portion is shaped such that its width widens from the boundary with the insertion portions at both ends towards the middle of its length, with both sides curving.

[0014] Furthermore, the gripping portion and the insertion portions at both ends are hollowed out on both sides in the thickness direction, and the intermediate portion sandwiched between the frame walls on both side edges forms the main rod wall. [Effect of the Invention]

[0015] In the parts remover according to this invention, the overall shape is rod-shaped, and a square prism-shaped insertion part is provided at one end of the gripping part, and a flat square prism-shaped insertion part is provided at the other end. Therefore, depending on the type of joint, either of the insertion parts can be inserted into the square hole, and by simply pulling and twisting the joint with one end of the contact part with the block plate as a fulcrum, the plug of the joint can be pulled out from the receiving port of the block plate, and the block plate and the joint can be separated.

[0016] And even if the assembled object with the parts connected is a cubic-shaped connector, it can be easily disassembled. By simply preparing the parts remover at hand, the connected parts can be separated easily without taking much time, and the parts can be rearranged easily many times to create various works, so the creativity of the user can be enhanced.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

[0019] The cubic connector shown in FIG. 1 is composed of combining a large block plate 11 with a square planar shape and a large joint 21 in which plugs 22 project in two directions perpendicular to each other, and can be disassembled by a parts mover. The joint 21 has prismatic side extensions 24 projecting from both sides of the base of the plug 22, and deep rectangular holes 25 opening at the end faces are formed in the side extensions 24, and the rectangular holes 25 have a square cross-sectional shape.

[0020] As shown in FIGS. 2 and 3, this parts mover has an overall rod-like shape and is provided with insertion parts 2 and 3 at both ends of the gripping part 1 respectively. Among the insertion parts 2 and 3, one insertion part 2 and the other insertion part 3 have different shapes.

[0021] As shown in FIG. 4, one insertion part 2 is made into a regular square prism corresponding to the case where the rectangular hole 25 in the side extension 24 of the joint 21 has a square cross-sectional shape, and engages so as not to rotate relatively when inserted into the rectangular hole 25 of this shape.

[0022] As shown in FIG. 5, when the rectangular hole 25 in the side extension 24 of the joint 21 is rectangular, or as shown in FIG. 6, when the cross-sectional shape is trapezoidal, the other insertion part 3 is made into a flat square prism that is wider and slightly thinner than one insertion part 2, and engages so as not to rotate relatively when inserted into the rectangular hole 25 of this shape.

[0023] The gripping portion 1 has a shape in which its width widens from the boundary with the insertion portions 2 and 3 at both ends towards the middle of its length, with both sides curving. This makes it easier to firmly grip the gripping portion 1 and apply force to the insertion portions 2 and 3.

[0024] The gripping portion 1 and the insertion portions 2 and 3 at both ends are hollowed out on both sides in the thickness direction, with the intermediate portion sandwiched between the frame walls 4 on both side edges forming the main rod wall 5. Ribs 6 are formed between the frame walls 4 on both side edges near both ends of the gripping portion 1 and at the boundary with the insertion portions 2 and 3. As a result, the parts remover is made lighter while maintaining strength.

[0025] When dismantling a cubic structure as shown in Figure 1 using a parts remover as described above, identify the joint 21 that forms one edge of the cubic structure, insert one insertion part 2 of the parts remover into the rectangular hole 25 of the joint 21, and pull the joint 21 by twisting it, using one end of the contact portion with the block plate 11 as a pivot point.

[0026] Then, by lifting the block plate 11 connected to this joint 21 and the surrounding joints 21 away from the other block plates 11 connected in the circumferential direction, and pulling out the plugs 22 from their sockets 12, the block plate 11 and joint 21 that form one face of the cubic connected body can be separated, and the cubic connected body can be easily dismantled.

[0027] Furthermore, as shown in Figure 5, when separating a joint 21 from a block plate 11, where the distance between the base ends of the plugs 22 is large and the rectangular hole 25 of the side extension 24 is rectangular, the other insertion part 3 of the parts remover is inserted into the rectangular hole 25 of the joint 21, and the joint 21 is pulled by twisting it using one end of the contact portion with the block plate 11 as a fulcrum.

[0028] Similarly, as shown in Figure 6, when separating a joint 21 from a block plate 11, where the plug 22 protrudes in two directions at a 120° angle and the rectangular hole 25 of the side extension 24 is trapezoidal, the other insertion part 3 of the parts remover is inserted into the rectangular hole 25 of the joint 21, and the joint 21 is pulled by twisting it with one end of the contact portion with the block plate 11 as the pivot point.

[0029] As described above, using this parts remover, depending on the type of joint 21, you can separate the block plate 11 and the joint 21 simply by inserting either the insertion part 2 or 3 into the square hole 25 and twisting the joint 21 using one end of the contact portion with the block plate 11 as a pivot point.

[0030] Furthermore, even if the assembled parts form a cubic structure, they can be easily disassembled. By simply having a parts remover on hand, users can easily rearrange the parts multiple times to create various works without the hassle of separating the connected parts, thus enhancing their creative motivation.
