Description

[Technical Field]

[0001] The present invention relates to an accessory member for assembly blocks that can be used to assemble various three-dimensional works. [Background technology]

[0002] Based on the invention described in Patent Document 1 below, the present applicant provides a plastic assembly block [product name: LaQ (registered trademark)], which is made up of a combination of block plates 3 with square and equilateral triangular planar shapes and joints 4 that connect the block plates 3 together, as shown in Fig. 12. Such assembly blocks are already widely available (see Patent Documents 2 to 4 below for actual shapes).

[0003] Sockets 31 are formed on each peripheral edge of the block plate 3, with recesses on the front and back sides, and protrusions 32 are provided in the sockets 31. Plugs 41 are provided in the joint 4 so as to protrude in at least two directions, and grooves 42 are provided on the inner surface of the plugs 41. Furthermore, between the bases of the plugs 41, rectangular column-shaped lateral extensions 43 extend on both sides.

[0004] When connecting such block plates 3 together, when the plug 41 of the joint 4 is fitted into the socket 31 of the block plate 3, the outer edge of the plug 41 abuts against the step at the back of the socket 31, the ridge 32 engages with the groove 42, and the lateral extension 43 abuts against the outer peripheral surface of the block plate 3, thereby stabilizing the connection.

[0005] There are several types of joints 4 depending on the connection method, and the basic type shown in the figure has plugs 41 that protrude in two directions on the same plane. Other types available include those with plugs 41 protruding in two perpendicular directions, those protruding in three perpendicular directions, those protruding in two directions at a 120° angle, and those with a large distance between the base ends of the plugs 41. By connecting square and equilateral triangular block plates 3 via these joints 4, it is possible to assemble three-dimensional works of art in various shapes, such as animals and vehicles.

[0007] However, using only the above-mentioned assembly block components, only rigid works can be assembled in which multiple block plates 3 are connected via joints 4, which results in a problem in that the variety of works is limited.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an accessory member for an assembly block that has an elastically bendable portion and can be used to assemble a variety of three-dimensional works. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides a flexible and elastic wide belt as an accessory member of an assembly block, which connects the block plates to each other via the joint when a plug of a joint is inserted into a socket of a block plate and lateral extensions extending from a base of the plug to both sides come into contact with the outer circumferential surface of the block plate, a plurality of elongated holes each having a width corresponding to the dimension between the end faces of the side extensions on both sides of the joint, the elongated holes extending in the width direction being arranged in a row in the length direction, and the length and width of the elongated holes being set to dimensions that allow the plug of the joint to be inserted; An accessory member for an assembly block is provided that can join the block plate and the joint by inserting the plug of the joint into the socket of the block plate through the elongated hole and sandwiching it between the outer peripheral surface of the block plate and the lateral extension of the joint.

[0010] Also, a narrow belt having flexibility and elasticity as an accessory member of an assembly block used in combination with the wide belt, a plurality of elongated holes each having a width narrower than the width of the wide belt and extending in the longitudinal direction are arranged in a row in the longitudinal direction, and the elongated holes have the same size and shape as the elongated holes of the wide belt; The width of the slot corresponds to the length of the slot so that it can be inserted into the slot of the wide belt, An accessory member for an assembly block is provided that can join the block plate and the joint by inserting the plug of the joint into the socket of the block plate through the elongated hole and sandwiching it between the outer peripheral surface of the block plate and the lateral extension of the joint.

[0011] The belt joint is an accessory member of an assembly block that connects the wide belt and the narrow belt to each other in any combination, and has a shape including a shaft portion and a head portion, The shaft portion has a square cross section and is a prism, and a locking portion having a larger cross section than the shaft portion is formed at the tip side of the shaft portion near the head, a length of one side of the cross section of the shaft-passing portion is set equal to or smaller than a width of the elongated hole, and a length of one side of the cross section of the locking portion is set greater than the width of the elongated hole, The wide belt and the narrow belt are overlapped in any combination, their long holes are connected, and when the shaft portion is pushed into the long hole from the locking portion, the through-shaft portion of the shaft passes through the long hole, and the overlapping wide belt and narrow belt are sandwiched and joined between the locking portion and the head of the shaft portion, thereby providing an accessory member for an assembly block. [Effects of the Invention]

[0012] By using the wide and narrow belts according to the present invention as appropriate, and inserting the plugs of the joints into the sockets of the block plates through the long holes in the belts, and joining the block plates to the joints, the wide and narrow belts can be bent elastically, allowing the assembly of a variety of three-dimensional works with dynamic curved parts.

[0013] Furthermore, by using belt joints in addition to wide and narrow belts, the wide and narrow belts can be combined in any desired manner and joined together in the extension or cross direction, greatly expanding the scale of works that can be assembled. [Brief explanation of the drawings]

[0015] The wide belt 1a, narrow belt 1b and belt joint 2 shown in FIG. 1 are accessory members of an assembly block whose basic components are block plates 3 shown in FIG. 12 and joints 4 that connect these block plates 3 together.

[0016] The wide belt 1a and the narrow belt 1b are made of flexible and elastic plastic sheet strips, and the joint 4 is made of hard plastic.

[0017] As shown in Fig. 2, the wide belt 1a has a plurality of elongated holes 11 extending in the width direction and arranged in a row in the length direction. The width Wa of the wide belt 1a corresponds to the length L between one side of the block plate 3 and the end faces of the side extensions 43 on both sides of the joint 4 shown in Fig. 12. The length h of the elongated holes 11 L and width h W is set to a size that allows the plug 41 of the joint 4 to be inserted.

[0018] As shown in Fig. 3, the narrow belt 1b has a width Wb narrower than the width Wa of the wide belt 1a, and has a plurality of longitudinally extending slots 11 arranged in a row along the length. The slots 11 of the narrow belt 1b have the same size and shape as the slots 11 of the wide belt 1a.

[0019] As shown in FIG. 4, the wide belt 1a and the narrow belt 1b are thin and flexible, and can be cut to any desired length using ordinary scissors.

[0020] As shown in FIG. 5, the narrow belt 1b is inserted into the long hole 11 of the wide belt 1a by adjusting the length h of the long hole 11. L The width Wb corresponds to

[0021] As shown in Fig. 6, the belt joint 2 has a rivet shape including a shaft portion 21 and a head portion 22. The shaft portion 21 is a prism with a square cross section. The shaft portion 21 has a locking portion 21b formed on the tip side of a through-shaft portion 21a closer to the head portion 22, the locking portion 21b having a larger cross section than the through-shaft portion 21a. The head portion 22 is disk-shaped.

[0022] The length Sa of one side of the square cross section of the shaft portion 21a is the width h of the slot 11. W The length Sb of one side of the cross section of the locking portion 21b is set equal to or slightly smaller than the width h of the elongated hole 11. W The diameter d of the head 22 is set to be slightly larger than the length Sb of one side of the cross section of the locking portion 21b.

[0023] When using such a belt joint 2, for example, as shown in Figure 7(a), the wide belts 1a are overlapped with each other with their orientations aligned, and with their elongated holes 11 connected, the shaft portion 21 is pushed into the elongated hole 11 from the locking portion 21b.

[0024] As the locking portion 21b is pushed in, the peripheral portion of the elongated hole 11 of the wide belt 1a elastically deforms, and as shown in Figure 7(b), the through-shaft portion 21a of the shaft portion 21 passes through the elongated hole 11. When the deformation of the peripheral portion of the elongated hole 11 of the wide belt 1a is restored, the overlapping wide belts 1a are sandwiched between the locking portion 21b of the shaft portion 21 and the head portion 22 and connected.

[0025] Similarly, as shown in FIG. 8, when narrow belts 1b are overlapped with each other in the same direction and their elongated holes 11 are connected, and shaft portion 21 is pushed into elongated hole 11 from locking portion 21b, shaft portion 21a passes through elongated hole 11, and overlapping narrow belts 1b are sandwiched and connected between locking portion 21b and head portion 22.

[0026] Although not shown, since the cross section of the shaft portion 21 of the belt joint 2 is square, the wide belt 1a and the narrow belt 1b can be joined by overlapping them in intersecting directions.

[0027] As shown in FIG. 9, the wide belt 1a and the narrow belt 1b can also be joined together by overlapping them in cross directions.

[0028] Then, the plug 41 of the joint 4 is inserted into the receiving port 31 of the block plate 3 through the long hole 11 of the wide belt 1a or the narrow belt 1b, and the block plate 3 and the joint 4 can be joined in a state in which the wide belt 1a or the narrow belt 1b is sandwiched between the outer peripheral surface of the block plate 3 and the lateral extension 43 of the joint 4.

[0029] When the wide belt 1a and narrow belt 1b as described above are connected by a belt joint 2 and used in combination with an assembly block whose basic components are a block plate 3 and a joint 4, it is possible to assemble a work such as a large display stand in which the mounting portion 5 is suspended in mid-air and swings, as shown in Figure 10.

[0030] Furthermore, as shown in Figure 11, by placing a relatively short piece of wide belt 1a between an animal body 6 and its base 7, which are each made up of block plates 3 and joints 4 and resemble an animal such as a lion, it is possible to assemble a figurine-like piece in which the animal body 6 swings relative to the base 7.

[0031] In this way, by using wide belt 1a and narrow belt 1b appropriately and inserting plug 41 of joint 4 into socket 31 of block plate 3 through long hole 11 of the belt, block plate 3 and joint 4 are joined, wide belt 1a and narrow belt 1b can be bent elastically, and various three-dimensional works with dynamic curved parts can be assembled.

[0032] Furthermore, by using the belt joint 2 in addition to the wide belt 1a and the narrow belt 1b, the wide belt 1a and the narrow belt 1b can be combined in any way and connected in the extension or cross direction, which greatly expands the scale of the works that can be assembled.

[0033] Furthermore, the wide belt 1a, narrow belt 1b, and belt joint 2 are accessories to existing assembly blocks and are used in combination with the block plate 3 and joint 4, which are basic parts. Therefore, users of existing assembly blocks can further expand the variety of works that can be assembled by purchasing these additional accessories. [Explanation of symbols]
