Description

[Technical Field]

[0001] The present invention relates to assembly blocks that can be assembled into any shape by connecting two or more blocks, and in particular to plate-shaped assembly blocks in which the blocks are connected to each other by slits. [Background technology]

[0002] BACKGROUND ART Conventionally, plate-shaped assembly blocks that are connected to each other by notches, slits, or the like provided in plate-shaped members have been widely known (see Patent Documents 1 and 2).

[0003] For example, Patent Document 1 discloses block-type building blocks that are configured to be connected from two directions by connecting two block-type building blocks using a connecting part consisting of protrusions and recesses arranged alternately on the four sides of the square, and a cross-shaped through hole in the center of the square, thereby strengthening the connecting force.

[0004] 5 of Patent Document 2 discloses a plate-like piece having a square through-hole with notches at the four corners. The plate-like piece of Patent Document 2 is configured so that other pieces can be connected by fitting them into the notches at the four corners of the through-hole. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model No. 2597744 [Patent Document 2] Patent Publication No. 2013-075691 Summary of the Invention [Problem to be solved by the invention]

[0006] On the other hand, there are locks for bags that require you to insert a rod-shaped locking member of roughly the same length as the slit into a slit in a plate-shaped member, then rotate the member so that it intersects with the slit, thereby locking the locking member. Turning such a key to lock it provides a certain enjoyment.

[0007] The inventor, upon seeing the key to this bag, came up with the idea of ​​applying this structure to assembly blocks, that is, connecting the two blocks by inserting one block into the other and rotating them.

[0008] In this regard, the block-type building blocks of Patent Document 1 can be connected by simply inserting the protrusion of one assembly block into the cross-shaped through-hole of the other block, and there is no need to rotate them.

[0009] Furthermore, with the plate-shaped piece of Patent Document 2, when fitting the notches of another piece into the notches at the four corners of the through hole of the plate-shaped piece, there is no need to rotate the other piece within the square through hole.

[0010] The present invention has been made in consideration of the above-mentioned problems, and aims to provide assembly blocks that are configured so that when two blocks are connected using a predetermined connecting method, they need to be connected by rotating them like a key to a bag. [Means for solving the problem]

[0011] The invention made to solve the above problem is an assembly block set including one assembly block and another assembly block, each having a plate thickness and a notch that cuts perpendicular to the plate thickness direction, and which can be connected by fitting the notch together. In the assembly block set of the present invention, one assembly block has a pair of first cut-out portions that are cut in opposing directions from a pair of opposing end sides, and a bridging portion that is the portion between the pair of first cut-out portions. The other assembly block includes a rotation through-hole penetrating in the plate thickness direction, and a slit portion having one or more second cutouts that cut from the rotation through-hole in a direction perpendicular to the plate thickness. The present invention is characterized in that the width of the bridging portion of the one assembly block is equal to or less than the width of the second notch of the other assembly block, the distance between the pair of end sides is set longer than the maximum diameter of the rotation through-hole of the other assembly block, and the one assembly block is inserted into the slit of the other assembly block, and with the bridging portion inserted into the rotation through-hole, the one assembly block is rotated relative to the other assembly block and around the axis of the bridging portion, and then the first notch of the one assembly block is fitted into the second notch of the other assembly block (← because the bridging portion may be narrower than the second notch, we will leave it as is rather than saying "fit the bridging portion of the one assembly block into the second notch of the other assembly block"; the same applies to claim 1), so that the one assembly block can be connected to the other assembly block.

[0012] In the assembly blocks of the present invention, the width of the bridging portion of one assembly block is equal to or smaller than the width of the second notch of another assembly block. Therefore, the width direction of the bridging portion can be aligned with the width direction of the second notch of the other assembly block, and the bridging portion can be fitted into the second notch. Furthermore, because the distance between the pair of end sides of one assembly block is longer than the maximum diameter of the rotation through-hole of the other assembly block, when inserting the one assembly block into the slit of the other assembly block, the one assembly block must be passed through the second notch of the other assembly block. Then, to align the width direction of the bridging portion with the width direction of the second notch, the one assembly block must be rotated relative to the other assembly block. This allows the person assembling the assembly blocks to enjoy rotating the assembly blocks. Furthermore, by changing the rotation angle, a wide variety of assembled shapes can be obtained.

[0013] The present invention also includes an invention relating to one of the assembly blocks alone in the assembly block set, and an invention relating to another of the assembly blocks alone.

[0014] It is preferable that the length of the second cutout portion of the other assembly block in the cutout direction is equal to or greater than the plate thickness of the first assembly block. This allows the user to enjoy sliding the bridge portion of one assembly block along the cutout portion of the other assembly block. Furthermore, by changing the sliding distance, a wide variety of assembly shapes can be obtained. [Effects of the Invention]

[0015] According to the present invention, when inserting and connecting one assembly block to another assembly block, the user can enjoy the operation of rotating the block like a key. [Brief explanation of the drawings]

[0017] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, however, the present invention is not limited to the following embodiment.

[0018] (First embodiment) 1 shows an assembly block set 100 according to a first embodiment of the present invention. The assembly block set 100 comprises one assembly block 1 and another assembly block 2. The one assembly block 1 and the other assembly block 2 are plate-shaped blocks with the same thickness t, and can be connected by fitting their respective notches 12, 224 together.

[0019] There are no particular restrictions on the material of the first assembly block 1 and the other assembly blocks 2, and any of wood, resin, and metal can be used, but wood is preferred because it is easy to process. Furthermore, the first assembly block 1 and the other assembly blocks 2 can be manufactured by any known manufacturing method appropriate for each material, but when wood is used, it is preferable to cut it with a laser.

[0020] As shown in Fig. 2, each assembly block 1 has a rectangular plate shape and includes a pair of first cutouts 12, 12 that cut into opposing directions from a pair of long sides (end sides) 11, 11 that face each other in the width direction (left-right direction in Fig. 2(c)), and a bridge portion 14 that is a portion between the pair of first cutouts 12, 12. In addition, a pair of auxiliary cutouts 15, 15 that cut into opposing directions are provided on a pair of short sides 13, 13 of each assembly block 1.

[0021] The width WA (see FIG. 2(c)) of the first cutout 12 perpendicular to the cutout direction and the plate thickness direction is approximately equal to the plate thickness t (see FIG. 2(a)), and is configured to be able to clamp another assembly block 2 in the plate thickness direction. The corners 12a, 12a at the entrance of the first cutout 12 are rounded to make it easier to insert another assembly block 2, and the corners 12b, 12b on the back side of the first cutout 12 are arc-shaped and concave to prevent cracks due to stress in the expanding direction of the first cutout 12 when another assembly block 2 is inserted into the first cutout 12.

[0022] The bridging portion 14 is a quadrangular prism-like bridge-shaped portion that is generated as a result of two opposing cutouts from the end sides 11, 11. It is important that the width WB of the bridging portion 14 (see FIG. 2(c)) is set to be equal to or smaller than the width WC of the second cutout 224 of another assembly block 2, which will be described later. In this embodiment, the width WA of the first cutout 12 and the width WC of the second cutout are substantially the same, but they may be different.

[0023] The auxiliary cut-out portions 15, 15 have a shape congruent with that of the first cut-out portion 12, and are configured to be able to sandwich another assembly block 2 in the thickness direction and connect to another assembly block 2. The auxiliary cut-out portion 15 is configured with protrusions 16, 16 that are rectangular in plan view and sandwich it. The width WD of the auxiliary cut-out portion 15 (see FIG. 2(c)) is set to be substantially the same as the plate thickness t of one assembly block 1, and is configured so that it can be sandwiched by the first cut-out portion 12 and the auxiliary cut-out portion 15.

[0024] 3, the other assembly block 2 according to this embodiment has a rectangular plate shape that is longer than the first assembly block 1, and is mainly provided with a substantially rectangular slit portion 22 that extends in the longitudinal direction (the up-down direction in FIG. 3(c)) at the center in the width direction (the left-right direction in FIG. 3(c)) and penetrates through in the plate thickness direction, as well as two pairs of first cut-out portions 12, 12 that are cut into the block from a pair of long sides (end sides) 21, 21 that face each other in the width direction, sandwiching the clamping portion 14. Since the other assembly block 2 has such first cut-out portions 22, 22, it also serves as the first assembly block. 2 indicates the short side of the other assembly block 2. The same reference numerals are used to designate the same parts of the other assembly block 2 as those of the one assembly block 1, and the description thereof will be omitted.

[0025] The slit portion 22 has a rotation through-hole 222 that penetrates in the plate thickness direction, and two notches 224, 224 that cut into the other assembly block 2 in the longitudinal direction from the rotation through-hole 222.

[0026] The maximum diameter D (see FIG. 3(c)) of the rotation through-hole 222 is smaller than the distance WD (see FIGS. 1(b) and 2(c)) between a pair of opposing end sides 11, 11 of one assembly block 1. This makes it impossible to insert one assembly block 1 only through the rotation through-hole 222, so that when inserting one assembly block 1 into the slit portion 22, as shown in FIG. 1(b), the direction of the width WC of the second cutout portion 224 is oriented in the direction of the plate thickness t of the one assembly block 1, and the one assembly block 1 is also passed through the second cutout portion 224.

[0027] Furthermore, the minimum diameter d (see FIG. 3(c)) of the rotation through-hole 222 is larger than the maximum radius 14b (see FIG. 3(d)) (in the illustrated example, the cross section 14a is rectangular, so the diagonal line) of the axis-perpendicular cross section 14a (see FIG. 2(d)) of the bridging portion 14. This allows the bridging portion 14 of one assembly block 1 to rotate about the axis while inserted through the rotation through-hole 222 of another assembly block 2.

[0028] The shape of the rotation through-hole 222 is not particularly limited and can be any shape, but a circular or elliptical shape is preferable so that an inserted assembly block can rotate smoothly. In Fig. 3, the rotation through-hole 222 is located in the center of the slit section 24 in the longitudinal direction, but as long as an inserted assembly block can be rotated, the rotation through-hole 222 may be located at a position offset to either side in the longitudinal direction, or at one of the longitudinal ends of the slit section 22.

[0029] The second cutout 224 has rounded corners 22a at the entrance and concave corners 22b at the rear. There are no particular limitations on the length L of the second cutout 224 in the cutout direction, but it is preferably longer than the plate thickness t of one assembly block 1. This allows the bridge portion 14 of one assembly block 1 to be fitted into the second cutout 224 with its plate thickness direction facing the cutout direction of the second cutout 224, and then to slide along the second cutout 224.

[0030] However, it goes without saying that one assembly block 1 may be fitted into the notch 224 with the width direction of the bridge portion 14 facing the notch direction of the notch 224.

[0031] It is important that the width WB of the bridging portion 14 is set to be equal to or less than the width WC of the second cutout 224 so that the width directions of the bridging portion 14 and the second cutout 224 can be aligned and the bridging portion 14 can fit into the second cutout 224, but it is particularly preferable to set the width WB to be less than the width WC. This makes it easier for the bridging portion 14 to enter and exit the second cutout 224, and allows the width direction of one assembly block 1 to be tilted with respect to the cut direction of the second cutout 224. One assembly block 1 may also be connected midway through the second cutout 224.

[0032] Furthermore, the shapes of the first cutout 12 and the second cutout 224 in the front view are not limited to a rectangular shape with a constant width along the cutout direction as in the example shown in the figure, and any shape can be used as long as it can sandwich the thickness of the other assembly block 2. They may be formed into a trapezoidal shape that widens in the cutout direction so as to sandwich the plate thickness of the assembly block to be connected near the opening, or they may be made narrower at an intermediate position in the cutout direction so as to sandwich the plate thickness of the assembly block to be connected at that part, or the width may gradually narrow towards the cutout direction.

[0033] (Assembling method) Next, a procedure for connecting and assembling one assembly block 1 and another assembly block 2 in the assembly block set 100 according to the first preferred embodiment will be described. When connecting one assembly block 1 to another assembly block 2, as shown in Figure 1(a), the short side 13 of the one assembly block 1 is brought into contact with the slit portion 22 of the other assembly block 2 while aligning the direction of the plate thickness t of the one assembly block 1 with the direction of the width WC of the second cutout portion 224 of the other assembly block 2 (both in the up-down direction in Figure 1(a)).

[0034] 1(b), one assembly block 1 is inserted across both the rotation through-hole 222 and the second cutout 224 of the other assembly block 2, and the other assembly block 2 is inserted in the direction of the arrow in the figure until the bridging portion 14 is housed inside the slit portion 22. When the bridging portion 14 is located inside the second cutout 224, the one assembly block 1 is slid in the longitudinal direction of the slit portion 22 to house the bridging portion 14 in the rotation through-hole 222.

[0035] Once the bridging portion 14 is housed in the rotation through-hole 222, the one assembly block 1 is rotated around the axis of the bridging portion 14 as shown by the arrow in Figure 1(c) so that the width WD direction of the one assembly block 1 is perpendicular to the longitudinal direction of the slit portion 22. In this way, like the key to a bag described above, the one assembly block 1 is locked so that it cannot be released from the other assembly blocks 2.

[0036] Thereafter, the bridge portion 14 is slid all the way into the second cut portion 224 as shown by the arrow in FIG. 1(d).

[0037] In this way, with the assembly block set 100 of this embodiment, it is possible to enjoy a two-stage operation of inserting one assembly block 1 into another assembly block 2, rotating it, and then sliding it, and it is also possible to realize a wide variety of fitting shapes.

[0038] As shown in Figure 1(e), the slit portion 22 of the other assembly block 2 is formed to a length that allows one horizontally positioned assembly block 1 to fit between two vertically oriented first assembly blocks 1. Also, as shown in Figure 1(f), the slit portion 22 of the other assembly block 2 has a length that allows one block 1 to be inserted and fitted horizontally into the second cutout portion 224, and then another first assembly block 1 to be inserted, and this second first assembly block 1 can also be fitted into the second cutout portion 224 on the opposite side.

[0039] (Second embodiment) Next, an assembly block set 200 according to a second embodiment will be described with reference to Figures 4 and 5. As shown in Figure 4, the assembly block set 200 comprises one assembly block 1 that is the same as in the first embodiment, and another assembly block 3 that is different from that in the first embodiment. Since the one assembly block 1 is the same as in the first embodiment, a description thereof will be omitted. In the first embodiment, the other assembly block 2 was rectangular, but in the second embodiment, the other assembly block 3 is triangular, as shown in Figure 5.

[0040] Another assembly block 3 according to this embodiment has a generally triangular plate shape, more specifically, a hexagonal plate shape in which three short sides 31 and three long sides 33 provided at three corners of the triangle are alternately arranged in the circumferential direction. As shown in Fig. 5(c), the assembly block 3 has a slit portion 32 that penetrates in the plate thickness direction at the center when viewed from the front. The slit portion 32 has a hexagonal rotation through-hole 322 provided in the center, and three cutouts 324, 324, 324 that cut radially at equal angular intervals from the rotation through-hole 322 toward the short sides 31.

[0041] The maximum diameter D (see FIG. 5(c)) of the rotation through-hole 322 is set smaller than the width WD (see FIG. 2(c)) between a pair of long sides (a pair of end sides as defined in the claims) 11, 11 of one assembly block 3, so that when one assembly block 1 is inserted into the slit portion 32 of another assembly block 2, it must be inserted so that it straddles the rotation through-hole 322 and one of the second cutout portions 324. This makes it necessary to rotate the one assembly block 1 when orienting the plate thickness direction of the bridging portion 14 of the one assembly block 1 in the cutout direction of the second cutout portion 324.

[0042] In addition, the second cutouts 324 are provided to be longer than the plate thickness t of the bridging portions 14 of one assembly block 1. This allows the bridging portions 14 of one assembly block 1 to be fitted into the second cutouts 324 with their plate thickness direction facing the cutout direction of the second cutouts 324, and then slid.

[0043] However, it goes without saying that one assembly block 1 may be fitted into the second cutout 324 with the width direction of the bridge portion 14 facing the cutout direction of the second cutout 324.

[0044] In addition, the other assembly blocks 3 have a total of six auxiliary cutouts 15 that cut vertically from the centers of the three short sides 31 and the centers of the three long sides 33.

[0045] (Assembling method) Next, a procedure for connecting and assembling one assembly block 1 and another assembly block 3 in the assembly block set 200 according to the second embodiment will be described. When connecting one assembly block to another assembly block 3, as shown in Figure 4(a), the direction of the plate thickness t of the one assembly block 1 is aligned with the direction of the width WC of one of the three cutouts 324 (vertical slit portion 32 in the example of Figure 4) of the other assembly block 3 (both aligned horizontally in Figure 4(a)), and the short side 13 of the one assembly block 1 is brought into contact with the slit portion 32 of the other assembly block 3.

[0046] 4(b), one assembly block 1 is inserted so as to straddle both the rotation through-hole 322 and the vertical second cutout 324 of the other assembly block 3 until the bridging portion 14 is accommodated inside the slit 32. If the bridging portion 14 is not accommodated in the rotation through-hole 322, the one assembly block 1 is slid in the longitudinal direction of the second cutout 324 to accommodate the bridging portion 14 in the rotation through-hole 322.

[0047] After the bridging portion 14 is accommodated in the rotation through-hole 322, one assembly block 1 is rotated around the axis of the bridging portion 14 as shown by the arrow in Figure 4(c) to align the direction of the plate thickness t of the one assembly block 1 with the notch direction of the second notch portion 324 on the left side of the slit portion (see Figure 4(a)).

[0048] 4(d), the bridge portion 14 is slid all the way into the second cutout portion 324 on the left side. In this way, the one assembly block 1 is locked to the other assembly block 3.

[0049] With the assembly block set 200 of this embodiment, it is possible to enjoy a two-stage operation of inserting one assembly block 1 into another assembly block 3, rotating it, and then sliding it, and it is also possible to realize a wide variety of fitting shapes.

[0050] As shown in FIG. 4(e), the slit portion 32 of the other assembly block 3 can accommodate the insertion of one assembly block 1 in a vertical position across the second cutout portion 324 and the rotation through-hole 322, with the horizontally oriented one assembly block 1 inserted all the way into the second cutout portion 324. Furthermore, as shown in Figure 4(f), the other assembly block 3 is configured so that when two single assembly blocks 1 are inserted into the adjacent second cutout portion 324 and auxiliary cutout portion 15 with the width direction as the cutout direction, the two single blocks 1 do not collide with each other.

[0051] (Third embodiment) 6 shows an assembly block set 300 according to a third embodiment of the present invention. The assembly block set 300 consists of a total of seven types of assembly blocks, including one assembly block 1 that is the same as in the first embodiment, three different types of one assembly blocks 4, 5, and 6, two other types of assembly blocks 2 and 3 according to the first and second embodiments, and another assembly block 7 that does not fall into either of the one assembly block or the other assembly blocks. All seven types of assembly blocks have the same plate thickness t. In the following description, the same members and parts as those in the first and second embodiments will be denoted by the same reference numerals and description thereof will be omitted.

[0052] As shown in Fig. 7(c), one assembly block 4 has a V-shape with a bent portion 42 that bends at an angle of approximately 55 degrees in the middle in the longitudinal direction (left-right direction in Fig. 7(c)). One assembly block 4 has two pairs of first cutouts 12, 12 on each side of the bent portion 42, facing each other across a bridge portion 14 in the width WD direction, as well as a pair of auxiliary cutouts 15, 15 on both ends of the longitudinal direction.

[0053] Like the first assembly block 4 (see FIG. 8(c)), the first assembly block 5 also has a V-shape with a bent portion 52 that bends at an angle of approximately 55 degrees in the middle in the longitudinal direction (left-right direction in FIG. 8(c)). The first assembly block 5 has, on one side (the left side in FIG. 8(c)) of the bent portion 52, a pair of first cutouts 12, 12 that face each other in the width WD direction with a bridging portion 14 therebetween, and also has a pair of auxiliary cutouts 15, 15 on both ends of the longitudinal direction.

[0054] As shown in Figure 9, one assembly block 6 has a rectangular plate shape and has three pairs of first cut-out portions 12, 12 that cut in opposing directions from a pair of long sides (end sides) 61, 61, as well as a pair of auxiliary cut-out portions 15, 15 at both ends in the longitudinal direction.

[0055] The other assembly block 7 is an assembly block that does not belong to either one assembly block or any other assembly block. As shown in Fig. 10, the other assembly block 7 is in the form of a rectangular plate, and has a pair of auxiliary cutouts 75 cut into both longitudinal edges. The auxiliary cutouts 75 have a width WA that can hold a plate thickness t, and a cutout length that is at least twice the plate thickness t, and are configured so that the bridging portions 14, 14 of two of the one assembly blocks can be overlapped and fitted into them.

[0056] The auxiliary cut-out portion 75 is composed of convex portions 76, 76 that are rectangular in plan view and sandwich it. The width WA of the auxiliary cut-out portion 75 is set to be substantially the same as the plate thickness t of one assembly block 1, and is set so as to be able to be sandwiched by the first cut-out portion 12, the second cut-out portions 224, 324, and the auxiliary cut-out portions 15, 75.

[0057] (Example of work) 11 and 12 show examples of works using seven types of assembly blocks 1 to 7 of the assembly block set 300 according to the third embodiment. The left side of Fig. 11 shows an elephant, the right side shows a giraffe, and Fig. 12 shows a beetle. As shown in Figs. 11 and 12, the first cutouts 12 may be fitted not only into the second cutouts 224 and 324 but also into the first cutouts 12 and auxiliary cutouts 15 and 75, or the plate thickness can be clamped at any position on the edge of each assembly block. In this way, the assembly blocks of the present invention not only provide the enjoyment of rotating and sliding when connecting, but also allow a wide variety of creations to be assembled.

[0058] As described above, the assembly blocks of the present invention are not limited to the above-described embodiments. For example, each assembly block is not limited to a rectangular, hexagonal, or V-shaped configuration, but can be other polygonal, circular, elliptical, star-shaped, or other shapes as appropriate. Two or more bent portions may be provided. The rotation through-holes are not limited to a circular, elliptical, or hexagonal configuration, but can be other shapes such as a square or rectangular configuration. The second cutouts may be less than the plate thickness of the bridging portion. The pair of opposing first cutouts do not have to be the same length, and the multiple second cutouts that cut from the rotation through-holes in a direction perpendicular to the plate thickness may also have different lengths.
