Background Art

[0002] Da Vinci bridge refers to an assembly method of constructing an arched or circular structure by mutually supporting flat or strip assembly units without using nails, ropes, glue, etc., or a shape constructed in this way.

[0003] The design of the Leonardo da Vinci Bridge utilizes the structural mechanics principles of force dispersion and mutual support, and has the advantages of quick and easy assembly and disassembly. Therefore, it is not only widely used in industrial purposes such as assembled simple buildings, tunnels, and military bridges, but also used as learning materials or toys for students.

[0004] For example, Korean Patent Publication No. 10-2023-0043494 (March 31, 2023) introduces a awning structure with a Da Vinci bridge structure consisting of a first upright unit, a second upright unit, and a connecting unit connecting them.

[0005] In addition, many learning materials or toy assembly kits based on the Da Vinci Bridge are also released on the Internet. Figure 1 and attached Figure 2 The invention cites toys using assembly units in the shape of a flat plate introduced on the conventional Internet.

[0006] The above-mentioned Da Vinci bridge toy is composed of three assembly units, namely, a plurality of arc units 100 forming an arc on both sides of the structure, a connecting unit 200 connecting the arc units 100 on both sides, and a finishing unit 300 supporting the arc units 100 and completing the arc.

[0007] Both sides of the arc-shaped unit 100 and one side of the tail unit 300 are respectively provided with inclined grooves (101, 301), and a horizontal groove (102, 302) is provided in the center.

[0008] At the same time, connecting protrusions 201 protrude from both sides of the connecting unit 200 .

[0009] Therefore, by alternately connecting the connecting protrusion 201 of the connecting unit 200 with the inclined half groove 101 and the horizontal half groove 102 of the arc unit 100, a Figure 1 In this case, the length of the arc unit 100 and the angles of the inclined grooves 101 on both sides determine the arc radius of the structure.

[0010] Patent Document (Patent Document 1) Patent Publication No. 10-2023-0043494 (March 31, 2023) Summary of the Invention

[0011] As attached Figure 1 As shown, the Da Vinci bridge assembly toy adopts a flat plate-shaped assembly unit made of, for example, MDF material, and is therefore very suitable as a learning material or toy for students.

[0012] However, the length of the arc member 100 and the angle of the inclined half groove (101) of the conventional Da Vinci bridge assembly unit are fixed, so the shapes and sizes of the shapes that can be made by these assembly units are very limited, thus restricting the user's creativity.

[0013] The problem to be solved by the present invention is to provide a Da Vinci bridge toy assembly kit, so that users can make models of various shapes and sizes based on the Da Vinci bridge structure according to their own creativity.

[0014] According to the present invention, the Da Vinci bridge assembly kit is characterized in that the assembly kit includes: a plurality of arc-shaped units 10, which are flat plate structures extending in the length L1 direction, and the two end faces are respectively provided with inclined half grooves 11 arranged obliquely in the length L1 direction and horizontal half grooves 12 arranged parallel to the length L1 direction, and a horizontal groove 13 parallel to the length L1 direction is provided in the center; a plurality of connecting units 20, which are flat plate structures extending in the length L2 direction, and the two end faces are respectively provided with connecting protrusions 21 combining the inclined half grooves 11, the horizontal half grooves 12 and the horizontal grooves 13 to form the Da Vinci bridge structure.

[0015] The connecting protrusion 21 of the connecting unit 20 has a structure in which the horizontal half groove 12 of the first arc-shaped unit 10 a and the horizontal half groove 12 of the second arc-shaped unit 10 b are oppositely coupled.

[0016] The connecting protrusion 21 of the connecting unit 20 has a structure in which the inclined half groove 11 of the first arc-shaped unit 10 a and the horizontal half groove 12 of the second arc-shaped unit 10 b are oppositely coupled.

[0017] According to the beneficial effects of the present invention, the Da Vinci bridge assembly kit can form arches or circular shapes with different diameters, and can produce various shapes such as heart shapes and flower shapes according to the user's creativity.

[0030] The present invention will be described in detail below using the accompanying drawings, which are only examples of preferred embodiments of the present invention and should not limit the scope of the present invention.

[0031] Even if components necessary for implementing the present invention have been described in conventional techniques or can be easily implemented by a person skilled in the art from known techniques, detailed descriptions thereof will be omitted.

[0032] Furthermore, the statement that a component "includes" other components means that in addition to the components in question, other components may be included as needed. Furthermore, in a rectangular component, the relatively narrow side is referred to as the "longitudinal width (Wa)" and the relatively wide side is referred to as the "lateral width (Wb)."

[0033] According to the present invention, the Da Vinci bridge toy assembly kit is composed of a plurality of flat arc units 10 and a plurality of flat connecting units 20. The thicknesses (T1, T2) of the arc units 10 and the connecting units 20 are preferably the same. Figure 3 As shown, it can be provided as a sheet of MDF, cardboard or compressed foam plastic material separated along a preset cutting line for use, or it can be provided as a separately injection-molded plastic product.

[0034] First, the arc unit 10 is as shown in the attached Figure 4 As shown, a flat plate structure extending along the length L1 and having a certain thickness T1 has an inclined half groove 11 and a horizontal half groove 12 on its two end surfaces. The inclined half groove 11 and the horizontal half groove 12 have an outwardly open structure and are arranged along the edge line of the arc unit 10.

[0035] The inclined half groove 11 is arranged at a certain angle relative to the length L1 direction of the arc-shaped unit 10, while the horizontal half groove 12 is arranged horizontally and parallel to the length L1 direction of the arc-shaped unit 10. The inclination angle of the inclined half groove 11, that is, the angle between the inclined half groove 11 and the horizontal half groove 12, is 20 to 40 degrees, and the preferred inclination angle is 30 degrees.

[0036] Furthermore, a horizontal groove 13 runs parallel to the horizontal plane through the center of the arc unit 10 along its length L1. The horizontal groove 13 is designed to enclose the interior of the arc unit 10. Each arc unit 10 has a bilaterally symmetrical structure, comprising two inclined half grooves 11, two horizontal half grooves 12, and one horizontal groove 13.

[0037] Next, the connection unit 20 is as follows Figure 5 As shown, the flat plate structure extending along the length L2 and having a certain thickness T2 has connecting protrusions 21 on both end surfaces. The connecting protrusions 21 are preferably bilaterally symmetrical structures, such as Figure 6 As shown, the inclined half grooves 11, the horizontal half grooves 12 and the horizontal grooves 13 of the arc-shaped unit 10 are alternately combined to form a Da Vinci bridge structure.

[0038] At this time, the longitudinal widths (Wa1, Wa2, Wa3) of the inclined half groove 11, horizontal half groove 12, and horizontal groove 13 of the arc-shaped unit 10 are preferably the same as the thickness T2 of the connecting protrusion 21 of the connecting unit 20. Therefore, the connecting protrusion 21 of the connecting unit 20 can be firmly connected to the inclined half groove 11, horizontal half groove 12, and horizontal groove 13.

[0039] Furthermore, the lateral widths (Wb1, Wb2) of the inclined half grooves 11 and the horizontal half grooves 12 are preferably less than or equal to half the lateral width (Wb4) of the connecting protrusion 21. Therefore, the two sides of a connecting protrusion 21 can be aligned with two inclined half grooves 11 or two horizontal half grooves 12, respectively.

[0040] Figure 6 The following illustrates the use of the assembly kit of the present invention, showing assembly modes B1 and B2 for connecting the connecting protrusion 21 of the connecting unit 20 to the three arcuate units (10a, 10b, and 10c). First, in assembly mode B1, the horizontal groove 13 of the third arcuate unit 10c is engaged on the inner side of the connecting protrusion 21, while the right-hand inclined half-groove 11 of the first arcuate unit 10a and the left-hand inclined half-groove 11 of the second arcuate unit 10b are engaged on the outer side.

[0041] Assembly mode B2 involves the right-hand inclined half-groove 11 of the first arc unit 10a and the left-hand inclined half-groove 11 of the second arc unit 10b being joined together on the connecting protrusion 21, while the horizontal groove 13 of the third arc unit 10c is joined on the outside. In other words, the inclined half-grooves 11 on either side of the arc unit 10 participate in two different assembly modes B1, while the horizontal groove 13 participates in assembly mode B2.

[0042] When the curved units 10 are assembled according to assembly modes B1 and B2, the angle of the inclined half-grooves 11 on either side determines the connection angle between the first curved unit 10a and the second curved unit 10b. For example, if the angle of the inclined half-grooves 11 is 30 degrees, the connection angle between the first curved unit 10a and the second curved unit 10b is 120 degrees. The connection angle between the first curved unit 10a and the second curved unit 10b is inversely proportional to the angle of the inclined half-grooves 11.

[0043] As described above, if the assembly mode B1 and the assembly mode B2 are alternately set on the connecting protrusions 21 on both sides of the connecting unit 20, the arc-shaped units 10 can be continuously combined to form a whole as shown in FIG. Figure 6 The arched Da Vinci bridge shape shown here. Here, the specifications of the arched shape are determined by the length L1 of the arc unit 10 and the angle of the inclined half groove 11.

[0044] In addition, in order to firmly maintain the assembly mode B1 and the assembly mode B2, the lateral width Wb4 of the connecting protrusion 21 is preferably the same as the lateral width Wb3 of the horizontal groove 13, and the longitudinal width Wa4 of the connecting protrusion 21 is preferably greater than twice the thickness T1 of the arc unit 10.

[0045] On the other hand, Figure 7 The present invention features assembly modes B3, B4, and B5 utilizing the horizontal half grooves 12. Assembly mode B3 involves first engaging the horizontal groove 13 of the third arc-shaped unit 10c with the connecting protrusion 21 of the connecting unit 20, and then engaging the right horizontal half groove 12 of the first arc-shaped unit 10a and the left horizontal half groove 12 of the second arc-shaped unit 10b on the outside to form a relative connection.

[0046] Assembly mode B4 is to first assemble the right side horizontal half groove 12 of the first arc unit 10a and the left side horizontal half groove (12) of the second arc unit 10b on the connecting protrusion 21 so that they are opposite to each other, and then assemble the horizontal groove 13 of the third arc unit 10c on the outside. When the arc units 10 are assembled according to the above assembly modes B3 and B4, the first arc unit 10a, the second arc unit 10b and the third arc unit 10c will extend straight along the length L1 direction.

[0047] The final assembly mode B5 involves first assembling the horizontal groove 13 of the third arc unit 10c on the connecting protrusion 21. Then, the horizontal half groove 12 of the first arc unit 10a and the inclined half groove 11 of the second arc unit 10b are assembled on the outside, so that they face each other. The left and right positions of the inclined half groove 11 and the horizontal half groove 12 can be reversed.

[0048] When the curved units 10 are assembled according to assembly pattern B5, the angle of the inclined half-groove 11 on one side determines the connection angle between the first curved unit 10a and the second curved unit 10b. For example, if the angle of the inclined half-groove 11 is 30 degrees, the connection angle between the first curved unit 10a and the second curved unit 10b is 150 degrees. In this way, the connection angle between the first curved unit 10a and the second curved unit 10b assembled according to assembly pattern B5 is wider than that of assembly patterns B1 and B2, increasing the angle of the inclined half-groove 11.

[0049] Attachment Figure 8 A new flower-shaped figure is demonstrated by properly arranging assembly patterns B1 and B5. In this way, the assembly kit of the present invention, in addition to assembly patterns B1 and B2, allows users to create figures of various shapes and sizes based on their creativity by properly arranging assembly patterns B3, B4, or B5. Compared to assembly patterns B1 and B2, the diameter of the figure increases as the number of assembly patterns B3, B4, or B5 increases.

[0050] On the other hand, Figure 9 Four circular shapes with different diameters are shown using the assembly kit of the present invention. Figure 9 The shape C1 is composed of 24 arc units 10 and 12 connecting units 20, the shape C2 is composed of 48 arc units 10 and 24 connecting units 20, the shape C3 is composed of 72 arc units 10 and 36 connecting units 20, and the shape C4 is composed of 96 arc units 10 and 48 connecting units 20.

[0051] It is worth noting that the existing flat plate shape assembly kits such as the attached Figure 1 As shown, since the length of the arc-shaped member 100 and the angles of the inclined half grooves 101 on both sides are fixed, it is impossible to form an arch or a circle shape, nor can it be formed as shown in the attached figure. Figure 7 or attached Figure 8 In addition, the following Figure 9 The circular shapes shown with different diameters are also not possible.

[0052] Finally, Figure 10 As an application example of the present invention, a circular lighting lamp made using the above-mentioned toy assembly kit is shown.
