Description

[Technical Field]

[0001] This invention relates to rotating parts of assembly blocks that can be used to assemble three-dimensional objects with movable parts. [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)] consisting of a combination of block plates 11 with square and equilateral triangular planar shapes and joints 21 that connect these block plates 11 together, as shown in Fig. 5. Such assembly blocks are already widely available (see Patent Documents 2 to 4 below for actual shapes).

[0003] A socket 12 is formed on each peripheral edge of the block plate 11, with recesses on the front and back sides, and a protrusion 13 is provided in the socket 12. A plug 22 is provided in the joint 21 so as to protrude in at least two directions, and a groove 23 is provided on the inner surface of the plug 22. In addition, a rectangular column-shaped lateral extension 24 extends on both sides between the bases of the plug 22.

[0004] When connecting such block plates 11 together, when the plug 22 of the joint 21 is inserted into the socket 12 of the block plate 11, the outer edge of the plug 22 abuts against the step at the back of the socket 12, the ridge 13 engages with the groove 23, and the lateral extension 24 abuts against the outer peripheral surface of the block plate 11, thereby stabilizing the connection.

[0005] There are several types of joints 21 depending on the connection manner, and in addition to the basic type in which the plugs 22 protrude in two directions on the same plane as shown in the figure, there are also types in which the plugs 22 protrude in two perpendicular directions, three perpendicular directions, two directions at an angle of 120°, and types in which the base ends of the plugs 22 are spaced apart by a large distance. By connecting square and equilateral triangular block plates 11 via these joints 21, it is possible to assemble three-dimensional objects of various shapes, such as animals and vehicles.

[0006] [Patent Document 1] Patent No. 3221637 [Patent Document 2] Design Registration No. 929785 [Patent Document 3] Design Registration No. 929786 [Patent Document 4] Design Registration No. 929787 Summary of the Invention [Problem to be solved by the invention]

[0007] In the assembly blocks described above, for example, when multiple block plates 11 are connected vertically and horizontally via joints 21 as shown in FIG. 6, holes 30 are formed surrounded by the lateral extensions 24 of the joints 21, and it is conceivable that these holes 30 can be used to expand the variety of works that can be made.

[0008] However, with only the basic parts as described above, it is not possible to create a work that actively utilizes the holes 30 as bearings for rotating parts, etc.

[0009] Therefore, an object of this invention is to make it possible to create works that have rotating parts by utilizing holes that are created when blocks are connected via joints. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems, the present invention provides an assembly block part in which, when a plug of a joint is inserted into a socket of a block plate to connect the block plates, a rectangular columnar side extension portion extending on both sides from the plug of the joint abuts against a side surface of the block plate, a pair of plugs common to the plugs of the joints are provided, and these plugs are connected via a shaft portion having a cylindrical outer periphery; In the assembled state in which the block plates are connected to each other and the shaft portion is inserted into the hole surrounded by the lateral extension portion of the joint, the block plates are rotatable around the axis of the shaft portion, and the block plates joined to the plugs connected to the shaft portion are rotatable relative to the portion composed of the other block plates and the joints (Configuration 1).

[0011] In the rotating part of the assembly block of configuration 1, the pair of plugs protrude from the shaft portion to both sides, In the assembled state, the portion consisting of the other block plate and the joint is sandwiched between the pair of plugs (Configuration 2).

[0012] Furthermore, in the rotating part of the assembly block of configuration 2, opposing surfaces of the pair of plugs sandwiching the shaft portion therebetween are smooth sliding surfaces, In the assembled state, as the shaft portion rotates around its axis, the sliding surfaces of the pair of plugs come into sliding contact with the surfaces of the other portion consisting of the block plate and the joint (Configuration 3). [Effects of the Invention]

[0013] When using the rotating parts of the assembly blocks of this invention, holes formed by connecting the block plates via joints can be used, and by inserting the shaft part of the rotating part into this hole, the block plate joined to the plug connected to the shaft part can be rotated freely relative to the other parts, thereby expanding the variety of works that can be assembled.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] As shown in FIG. 1, the rotating part 25 includes a pair of plugs 22, which are connected via a shaft portion 26 having a cylindrical outer periphery.

[0017] The plug 22 has the same size and shape as the plug 22 of the joint 21 of the basic part shown in Figure 5, and is intended to be inserted into the socket 12 of the block plate 11. The inner surface of the plug 22 is provided with a groove 23 that engages with the protrusion 13 of the block plate 11.

[0018] The pair of plugs 22 protrude to both sides from the shaft portion 26, and the opposing surfaces of the pair of plugs 22 sandwiching the shaft portion 26 are smooth sliding surfaces 22a. The distance between the sliding surfaces 22a of the opposing plugs 22 in the rotating part 25 is slightly larger than the thickness of the block plate 11 and the joint 21.

[0019] The diameter of the base portion of the shaft portion 26 at the boundary with the sliding surface 22a is slightly smaller than the thickness of the plug 22, and the diameter of the middle portion sandwiched between the base portions is further reduced from the base portion via a step.

[0020] When connecting such rotating parts 25 to a plurality of block plates 11 vertically and horizontally via joints 21 as shown in FIG. 6, for example, to form an assembly with a rotating part by utilizing holes 30 surrounded by lateral extensions 24 of the joints 21, as shown in FIGS. 2 and 3, the plugs 22 of the rotating parts 25 are inserted into the sockets 12 of the block plates 11, and before closing the periphery of the holes 30, the shaft portions 26 are fitted into the recesses that will become the holes 30.

[0021] Then, the block plate 11 and the joint 21 are joined together to close the periphery of the hole 30, and the shaft portion 26 is inserted through the hole 30.

[0022] This allows the rotating part 25 to rotate around the axis of the shaft portion 26, and the block plate 11 joined to the plug 22 connected to the shaft portion 26 can rotate freely relative to the part consisting of the other block plate 11 and the joint 21.

[0023] As the rotating part 25 rotates, the sliding contact surfaces 22 a of the pair of plugs 22 of the rotating part 25 come into sliding contact with the surface of the portion consisting of the other block plate 11 and the joint 21 .

[0024] Furthermore, the pair of plugs 22 of the rotating part 25 protrude on both sides from the shaft portion 26, and the dimension between both ends of the sliding surfaces 22a of the plugs 22 is larger than the maximum length of the inner dimensions of the hole 30, so even if the block plate 11 is not joined to one of the plugs 22, the rotating part 25 will not slip out of the hole 30.

[0025] By using the rotating part 25 as described above, the block plate 11 joined to the plug 22 connected to the shaft 26 can be freely rotated relative to the other parts by inserting the shaft 26 of the rotating part 25 into the hole 30 formed by the connection of the block plate 11 via the joint 21, and as a result, it is possible to assemble a work such as a snowman with rotating hands, as shown in Figure 4, for example.

[0026] Furthermore, this rotating part 25 is a type of joint for existing assembly blocks that are widely used, and can be connected to the block plate 11, which is a basic part. Therefore, users of existing assembly blocks can further expand the variety of works that can be assembled by additionally purchasing this rotating part 25. [Explanation of symbols]
