Description

  The present invention relates to a part remover for an assembly block in which block plates can be sequentially connected via a joint to assemble a three-dimensional work.

  Based on the invention described in Patent Document 1 below, the applicant of the present invention is a combination of a block plate 11 having a square shape and a regular triangle as shown in FIG. 15 and a joint 21 for connecting the block plates 11 to each other. An assembly block made of plastic [trade name: LaQ (registered trademark)] is provided, and such assembly blocks are widely distributed. The actual shape of the block plate 11 is as described in Patent Documents 2 and 3 below.

  On each side around the block plate 11, a receiving port 12 having a recessed front surface side and a back surface side is formed, and a protrusion 13 is provided on the receiving port 12. The joint 21 is provided with a plug 22 with tongues facing each other in at least two directions, and a groove 23 is provided on the inner surface of the plug 22. Further, a prismatic side extending portion 24 projects from the base portion of the plug 22 to both sides, and a hole 25 is formed on the end surface of the side extending portion 24 which is both ends of the joint 21.

  When the block plates 11 are connected to each other, when the plug 22 of the joint 21 is fitted into the receiving port 12 of the block plate 11, the outer edge of the plug 22 comes into contact with the step on the back side of the receiving port 12 and the protrusion 13 Engages the groove 23 and the side extension 24 abuts against the outer peripheral surface of the block plate 11 to stabilize the connected state.

  There are a plurality of types of joints 21 depending on the connection mode. As shown in the figure, the basic structure in which the plug 22 protrudes in two directions on the same plane as shown in the drawing, and the two directions in which the plug 22 is orthogonal , Those projecting in three orthogonal directions, those projecting in two directions at an angle of 120 °, and those having a large distance between the proximal ends of the plugs 22 are prepared.

  Then, as shown in FIG. 3, when the square block plate 11 and the joint 21 projecting in two directions perpendicular to the plug 22 are combined, a cubic connecting body can be assembled as shown in FIG. . In addition, although not shown in the figure, a spherical connecting body can be assembled by combining the equilateral triangular block plate 11 and the joint 21 in which the plug protrudes in two directions at an angle of 120 °.

  Further, as a special part of the assembly block, as shown in FIG. 7, the joint 21 is provided with a plug 22 projecting in three orthogonal directions, and a shaft 26 extending from between the bases of the plug 22 projecting in the opposite direction. There is also a wheel member 31 that is inserted into the shaft 26 and attached. The wheel member 31 is configured such that a rubber tire 33 is fitted to a wheel 32 having a flange at one end of a rim portion (see Patent Document 4 below).

  And as shown in FIG. 8, the joint 21 and the wheel member 31 provided with such a shaft 26 are couple | bonded, The coupling body and the coupling body which connected the block board 11 via the basic joint 21 are connected. When combined, the car body is assembled.

  By the way, in order to separate the connected block plate 11 and the joint 21, the block plate 11 and the joint 21 are held and bent so that the connection portion is folded. As a result, the plug 22 is bent so as to be opened, and the plug 22 is removed from the receiving port 12 and can be easily separated. Further, when disassembling the spherical connecting body, if a force is applied by wrapping with a hand, the plug 22 is bent so as to open, and can be easily disassembled.

  However, the cube-shaped connection body as shown in FIG. 4 cannot be disassembled by the above-described method, and when disassembling, a pin tip of a push pin is inserted into the hole 25 of the joint 21 exposed at the corner. There is a problem that it is necessary to pull the block plate 11 on one side and the joint 21 around it to the outside so that disassembly is difficult.

  Further, as shown in FIG. 8, when the wheel member 31 is mounted on the joint 21 having the shaft 26, the shaft 26 is engaged with the center hole of the wheel 32 along with the elastic diameter reduction and restoration by the split groove. Therefore, there is a problem that even if the wheel member 31 is removed from the shaft 26, the wheel member 31 is difficult to come off.

  Furthermore, since the wheel 32 and the tire 33 of the wheel member 31 are used separately, even if the wheel 32 and the tire 33 are to be separated, the tire 33 is elastically adhered to the rim portion of the wheel 32 and the inner side of the wheel 32. There is also a problem that it is difficult to disengage from the wheel 32.

  Therefore, an object of the present invention is to make it possible to easily separate the parts to which the assembly blocks are connected and to easily reassemble the parts many times.

In order to solve the above-mentioned problem, the present invention comprises a combination of a block plate having a receiving port around it and a joint provided with a plurality of plugs inserted into the receiving port so as to protrude in different directions. A part remover of an assembly block having a hole in the

Further, on the inner side of the pair of arms, a wedge portion made of a slope inclined so as to be separated from the reference surface from the distal end side to the proximal end side is provided,
The parts to be separated are a joint in which the shaft extends from between the bases of the plugs protruding in opposite directions, and a wheel member that is inserted into the shaft and attached to the joint.
When the joint and the wheel member are coupled, the wedge part is inserted between the plug and the wheel member from the distal end side of the arm, and the joint and the wheel member are slid along the wedge part to the base side of the arm. The wheel member is removed from the shaft of the joint so that the joint and the wheel member are separated.

On the base side of the pair of arms, a pedestal portion is provided, and on the pedestal portion, a tube extraction portion having a smaller diameter than a wheel rim portion of a wheel member is erected,
The parts to be separated are the wheel and tire of the wheel member,
With the tire fitted on the wheel of the wheel member, when the diameter surface opposite to the flange of the wheel is brought into contact with the distal end surface of the extraction tube portion and the tire is slid to the pedestal portion side, the tire comes off from the wheel. It was decided to provide what would be separated.

  In the parts remover according to the present invention, since the engagement projections projecting inward are provided at the tip portions of the pair of arms, the joint projections are engaged with the holes using the holes at both ends of the joint, By pulling the plug while pulling out the plug, the block plate and the joint can be separated without using a push pin or the like, and the cube-shaped connection body can be easily disassembled.

  Further, since the wedge portion having the slope is provided inside the pair of arms, when separating the joined joint and the wheel member, the wedge portion is inserted between the plug and the wheel member from the distal end side of the arm, and the joint and the wheel member are inserted. Is simply slid along the wedge to the base side of the arm, the wheel member can be removed from the shaft, and the joint and the wheel member can be easily separated.

  In addition, since the cylindrical portion having a smaller diameter than the wheel of the wheel member is erected on the pedestal portion located on the base side of the pair of arms, the diameter surface of the wheel is changed with the tire fitted on the wheel of the wheel member. The wheel and the tire can be easily separated simply by making contact with the distal end surface of the tube-extracting portion and sliding the tire toward the pedestal portion.

  And by making it a multifunctional part remover with each of the above functions, you can easily reassemble parts many times without having to separate the connected parts by simply preparing one part remover at hand. In addition, various works using assembly blocks can be created, and the user's willingness to create can be enhanced.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The part remover shown in FIGS. 1 and 2 is a member attached to the assembly block as described above, and is used to separate parts of the connected assembly block.

  This part remover is a plastic molded product, and has a shape in which a pair of arms 1 are connected in a bifurcated manner by a connecting portion 2 on the base side. The pair of arms 1 can be opened and closed in a direction in which the distal ends separate from each other and in a direction in which the pair of arms 1 are bent within the elastic limit. The pair of arms 1 are bent toward the outside so that the wheel member 31 can be inserted in the vertical direction at a portion near the tip in the length direction, and the tip side is bent inward.

  Further, a clamping surface 4 is formed inside the projecting portion from the abutting surface 3 and the abutting surface 3 in the width direction at the distal end portions of the pair of arms 1, and the projection projects inward from the clamping surface 4. A protrusion 5 is formed. The engaging protrusion 5 is formed with an inclined surface 5 a that is retracted from the proximal end side to the distal end side on the opposite side of the abutting surface 3.

The distance D ₁ between the opposing clamping surfaces 4 of the pair of arms 1 is substantially equal to the length between both end faces of the joint 21, and the distance D ₂ between the tips of the opposing engagement protrusions 5 of the pair of arms 1 is the joint 21. It is smaller than the length between both end faces.

  In addition, a wedge portion 6 including a reference surface 6a and a slope 6b inclined so as to be separated from the front end side to the base end side is provided inside the pair of arms 1.

  Further, on the outer surfaces of the pair of arms 1, there is formed a grip portion 1a having a non-slip process composed of a plurality of grooves at a portion where the distance between the front ends is widened, and the arm closer to the connecting portion 2 than the grip portion 1a. Each of the two concave grooves 1b is formed so that 1 is easily bent.

  In addition, a pedestal portion 7 extending from the connecting portion 2 is provided on the base side of the pair of arms 1, and the pedestal portion 7 has a tube extraction portion 8 having a smaller diameter than a rim portion 32 a of a wheel 32 of a wheel member 31 described later. Is erected. A receiving port 7a similar to that of the block plate 11 is formed at the end edge of the pedestal portion 7, and a shaft hole 8a into which the shaft 26 is fitted is formed at the central portion of the extracted tube portion 8.

  When disassembling a cube-shaped connecting body as shown in FIG. 4 using the parts remover as described above, the joint 21 forming one ridge portion of the cube-shaped connecting body is determined, and FIG. First, the engagement protrusion 5 at the tip of one arm 1 is engaged with the hole 25 on one end surface of the joint 21.

  Subsequently, when the engaging projection 5 at the tip end of the other arm 1 is pressed against the outer surface of the other end of the joint 21, the inclined surface 5 a of the engaging projection 5 of the other arm 1 becomes the other end of the joint 21. The tip end side of the pair of arms 1 is pushed and spread by abutting and sliding on the outer surface of the part.

  When the engagement protrusion 5 of the other arm 1 is fitted into the hole 25 on the other end face of the joint 21, the pair of arms 1 are elastically restored as shown in FIG. The mating protrusions 5 are engaged with the holes 25 on both end surfaces of the joint 21.

  In this state, the outer surface of the side extending portion 24 of the joint 21 abuts against the abutting surface 3 of the distal end portion of the pair of arms 1, and both end surfaces of the joint 21 are sandwiched between the sandwiching surfaces 4 of the distal end portions of the pair of arms 1. The parts remover is stabilized against the joint 21.

  Thereafter, as shown in FIG. 6, the grip portion 1 a is gripped so that the force acts in the direction in which the tip ends of the pair of arms 1 are closed, and the joint plate 21 and the block plate 11 coupled to the joint 21 are gripped while holding the joint 21. The surrounding joints 21 are pulled up from the other block plates 11 connected in the circumferential direction, and the plugs 22 are pulled out from the receiving ports 12.

  Thereby, even if it does not use a push pin etc., the block board 11 and the joint 21 can be isolate | separated, and a cube-shaped connection body can be disassembled easily.

  Next, a procedure for removing the wheel member 31 from the shaft 26 of the joint 21 used in the work as shown in FIG. 8 using the parts remover as described above will be described.

  When separating the parts, as shown in FIG. 9, the side extension 24 of the joint 21 is sandwiched between the opposing wedge portions 6 of the pair of arms 1 in a state where the joint 21 and the wheel member 31 are coupled. The wheel member 31 is set along the reference surface 6a, the plug 22 protruding in the opposite direction of the joint 21 is set along the slope 6b, and the wedge portion 6 is moved to the arm 1 as shown in FIG. It is inserted between the plug 22 and the wheel member 31 from the front end side.

  10 (II), when the joint 21 and the wheel member 31 are slid along the wedge portion 6 from the distal end side of the arm 1 to the base side, the distance between the plug 22 of the joint 21 and the wheel member 31 is increased. It spreads and the wheel member 31 comes out of the shaft 26, and the joint 21 and the wheel member 31 can be easily separated.

  Next, a procedure for separating the wheel 32 and the tire 33 of the wheel member 31 using the parts remover as described above will be described.

  When separating the parts, as shown in FIG. 11, with the tire 33 fitted on the wheel 32 of the wheel member 31, the radial surface opposite to the flange 32b of the wheel 32 is removed as shown in FIG. The tire 33 is slid toward the pedestal portion 7 while being brought into contact with the distal end surface of the cylindrical portion 8. Thereby, the tire 33 comes out from the rim portion 32a of the wheel 32, and the wheel 32 and the tire 33 can be easily separated.

  As shown in FIG. 13, since the base 7 of the parts remover is formed with a receiving port 7a similar to the receiving port 12 of the block plate 11, various types of receiving parts 7a can be used by using the receiving port 7a. The joint 21 and the block plate 11 can be temporarily held so as not to be lost.

  Further, since the shaft hole 8a into which the shaft 26 is fitted is formed at the center of the tube extraction portion 8, when the joint 21 having the shaft 26 is used, the shaft 26 is inserted into the shaft hole 8a. The joint 21 can be temporarily held.

  In this way, the above part remover is multi-functional, so just prepare one part remover at hand, and easily and easily remove parts without having to separate connected parts. By rearranging it, you can make various works with assembly blocks, and you can increase your willingness to create.
