Abstract
Description
Technical Field
[0001] The present invention relates to a Da Vinci Bridge toy assembly set. More specifically, it relates to a toy assembly set including a plurality of flat plate-shaped arc units (10) provided with inclined half grooves (11) and horizontal half grooves (12) on both short sides respectively, and a horizontal slot (13) penetrating through the center, and a plurality of flat plate-shaped linker units (20) provided with coupling convex portions (21) on both short sides respectively. By alternately coupling the inclined half grooves (11), horizontal half grooves (12) and horizontal slots (13) of the arc units (10) to the coupling convex portions (21) of the linker units (20), it can form various shaped objects such as a Da Vinci Bridge.
Background Art
[0002] The Da Vinci Bridge refers to an assembly method of constructing an arc-shaped or circular structure by mutually supporting flat plate or rod-shaped assembly units without using nails, strings, adhesives, etc., or a shaped object constructed by that method.
[0003] The shaped object of the Da Vinci Bridge utilizes the structural mechanics principle of force dispersion and mutual support, and has the advantages of being quickly and easily assembled and disassembled. It is widely used not only in industrial applications such as assembled simple buildings, tunnels, and military bridges, but also as learning materials and toys for students.
[0004] For example, Korean Patent Publication No. 10-2023-0043494 (March 31, 2023) introduces a canopy structure assembled in a Da Vinci Bridge structure with a first upright unit, a second upright unit, and a connecting unit connecting them.
[0005] In addition, there are also many learning materials and toy assembly sets using the Da Vinci Bridge published on the Internet. Attached FIGS. 1 and 2 cite toys using flat plate-shaped assembly units among the conventional Da Vinci Bridge assembly sets introduced on the Internet.
[0006] Conventional Da Vinci Bridge toys consist of three types of assembly units: multiple arc units (100) that form arcs on both sides of the structure, linker units (200) that connect the arc units (100) on both sides, and finishing units (300) that support the arc units (100) and finish the arc shape.
[0007] The short sides of the arc unit (100) and one end of the finishing unit (300) are provided with inclined half-grooves (101, 301), and horizontal slots (102, 302) are provided in the center of each groove.
[0008] Furthermore, connecting protrusions (201) protrude from both short sides of the linker unit (200).
[0009] Therefore, by alternately connecting the inclined half-grooves (101) and horizontal slots (102) of the arc unit (100) to the connecting protrusions (201) of the linker unit (200), an arc-shaped structure as shown in Figure 1 is manufactured. At this time, the arc radius of the structure is determined by the length of the arc unit (100) and the angle of the inclined half-grooves (101) on both sides. [Prior art documents] [Patent Documents]
[0010] [Patent Document 1] Korean Published Patent No. 10-2023-0043494 (March 31, 2023) [Overview of the project] [Problems that the invention aims to solve]
[0011] As shown in Figure 1, the Da Vinci Bridge assembly toy is very suitable for student learning materials and toys because it uses flat assembly units made of, for example, MDF material.
[0012] However, conventional Da Vinci Bridge assembly units have fixed lengths for the arc units (100) and angles for the inclined half-grooves (101), which severely limits the form and size of the objects that can be produced using these assembly units, thus limiting the user's ability to exercise creativity.
[0013] Therefore, the problem that this invention aims to solve is to provide a Da Vinci Bridge toy assembly set that allows users to create various forms and sizes of sculptures based on the Da Vinci Bridge structure, using their own creativity. [Means for solving the problem]
[0014] The Da Vinci Bridge assembly kit according to the present invention is It has a flat plate structure extended in the length (L1) direction, with inclined semi-grooves (11) positioned diagonally to the length (L1) and horizontal semi-grooves (12) positioned parallel to the length (L1) on both ends, and multiple arc units (10) through which horizontal slots (13) arranged in the length (L1) direction pass; A plurality of linker units (20) having a flat plate structure extended in the length (L2) direction, with connecting protrusions (21) on both ends that connect with the inclined half groove (11), horizontal half groove (12), and horizontal slot (13) respectively to form a Da Vinci bridge structure; This is a toy assembly set characterized by being composed of the following:
[0015] The linker unit (20) is characterized in that the connecting projection (21) is connected such that the horizontal half groove (12) of the first arc unit (10a) and the horizontal half groove (12) of the second arc unit (10b) face each other.
[0016] Furthermore, the linker unit (20) is characterized in that the connecting projection (21) is connected to the inclined half-groove (11) of the first arc unit (10a) and the horizontal half-groove (12) of the second arc unit (10b) so that they face each other.
Advantages of the Invention
[0017] According to the Da Vinci Bridge toy assembly set of the present invention, it is possible to form arc-shaped or circular objects with different diameters, and thus it has the effect that various forms of objects such as heart shapes and flower shapes can be produced by the creativity of the user.

Modes for Carrying Out the Invention
[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the accompanying drawings illustrate a preferred example of the present invention, and the technical scope of the present invention is not limited by these examples.
[0020] Even if a configuration is absolutely necessary for carrying out the present invention, a detailed explanation will be omitted if it is described in the prior art or if it can be easily implemented by a person skilled in the art from the prior art.
[0021] Furthermore, "includes" means that, in addition to the explicitly stated components, other components may be included as needed. In addition, in rectangular components, the narrower side is called the "vertical width (Wa)" and the wider side is called the "horizontal width (Wb)".
[0022] The Da Vinci Bridge toy assembly set of the present invention comprises a plurality of flat arc units (10) and a plurality of flat linker units (20). The arc units (10) and linker units (20) preferably have the same thickness (T1, T2), and can be provided so as to be separated and used along cutting lines provided in a sheet material of MDF, hardboard paper, or compressed polystyrene foam, as shown in Figure 3, and can also be provided as separately injection-molded plastic products.
[0023] First, as shown in Figure 4, the arc unit (10) is a flat plate structure that extends in the length direction (L1) and has a predetermined thickness (T1), and is provided with an inclined semi-groove (11) and a horizontal semi-groove (12) on both short sides. The inclined semi-groove (11) and the horizontal semi-groove (12) each have a structure that is open to the outside along the frame line of the arc unit (10).
[0024] The inclined half-groove (11) is positioned at a predetermined angle with respect to the length (L1) direction of the arc unit (10), and the horizontal half-grooves (12) are positioned side by side in the length (L1) direction. 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 approximately 20 to 40 degrees, with a desirable inclination angle of 30 degrees.
[0025] Furthermore, horizontal slots (13) are arranged horizontally in the direction of the arc unit (10) length (L1) through the center of the arc unit (10). The horizontal slots (13) have a structure that is closed inside the arc unit (10). Each arc unit (10) has two inclined half grooves (11), two horizontal half grooves (12), and one horizontal slot (13) arranged in a symmetrical structure.
[0026] Next, as shown in Figure 5, the linker unit (20) is a flat plate structure that extends in the length direction (L2) and has a predetermined thickness (T2), with connecting protrusions (21) provided on each of the short sides. The connecting protrusions (21) preferably form a symmetrical structure, and as shown in Figure 6, the inclined half grooves (11), horizontal half grooves (12), and horizontal slots (13) of the arc unit (10) are alternately connected to form a Da Vinci bridge structure.
[0027] In this case, it is desirable that the vertical widths (Wa1, Wa2, Wa3) of the inclined half groove (11), horizontal half groove (12), and horizontal slot (13) of the arc unit (10) be the same as the thickness (T2) of the connecting projection (21) of the linker unit (20). Therefore, the inclined half groove (11), horizontal half groove (12), and horizontal slot (13) are firmly connected to the connecting projection (21) of the linker unit (20).
[0028] Furthermore, it is desirable that the widths (Wb1, Wb2) of the inclined semi-grooves (11) and the horizontal semi-grooves (12) are less than half the width (Wb4) of the connecting projection (21). Therefore, two inclined semi-grooves (11) or two horizontal semi-grooves (12) can be connected to one connecting projection (21) so as to face each other on both sides.
[0029] Figure 6 shows examples of using the assembly set according to the present invention, illustrating coupling patterns B1 and B2 in which three arc units (10a, 10b, 10c) are combined with the coupling projection (21) of the linker unit (20). First, in coupling pattern B1, the horizontal slot (13) of the third arc unit (10c) is coupled to the inside of the coupling projection (21), while the right-side inclined half-groove (11) of the first arc unit (10a) and the left-side inclined half-groove (11) of the second arc unit (10b) are coupled to the outside of it, facing each other.
[0030] In coupling pattern B2, the right-side inclined half-groove (11) of the first arc unit (10a) and the left-side inclined half-groove (11) of the second arc unit (10b) are coupled to the coupling projection (21) so as to face each other, and the horizontal slot (13) of the third arc unit (10c) is coupled to the outside of them. That is, the inclined half-grooves (11) on both sides of the arc unit (10) are involved in two different coupling patterns B1, and the horizontal slot (13) is involved in coupling pattern B2.
[0031] In this way, when the arc units (10) are joined according to joining patterns B1 and B2, the connection angle between the first arc unit (10a) and the second arc unit (10b) is determined by the inclination angle of the inclined half grooves (11) on both sides. For example, if the angle of the inclined half groove (11) is 30 degrees, the connection angle between the first arc unit (10a) and the second arc unit (10b) will be 120 degrees. The connection angle between the first arc unit (10a) and the second arc unit (10b) is inversely proportional to the inclination angle of the inclined half groove (11).
[0032] In this way, by continuously connecting arc units (10) to the connecting protrusions (21) on both sides of the linker unit (20) such that connecting patterns B1 and B2 are alternately arranged, the overall structure is an arc-shaped Da Vinci Bridge as shown in Figure 6. At this time, the specifications of the arc-shaped structure are determined by the length (L1) of the arc unit (10) and the angle of the inclined half-groove (11).
[0033] Furthermore, in order to firmly maintain the joint patterns B1 and B2, it is desirable that the width (Wb4) of the joint protrusion (21) be the same as the width (Wb3) of the horizontal slot (13), and that the height (Wa4) of the joint protrusion (21) be at least twice the thickness (T1) of the arc unit (10).
[0034] Furthermore, as shown in Figure 7, coupling patterns B3, B4, and B5, which utilize the horizontal half-grooves (12) that are a feature of the present invention, are shown. In coupling pattern B3, the horizontal slot (13) of the third arc unit (10c) is coupled to the coupling projection (21) of the linker unit (20), and the right horizontal half-groove (12) of the first arc unit (10a) and the left horizontal half-groove (12) of the second arc unit (10b) are coupled side by side facing each other.
[0035] In joining pattern B4, the right horizontal half groove (12) of the first arc unit (10a) and the left horizontal half groove (12) of the second arc unit (10b) are first joined to the joining protrusion (21) so that they face each other, and the horizontal slot (13) of the third arc unit (10c) is joined to the outside of them. When the arc units (10) are joined according to joining patterns B3 and B4, the first arc unit (10a), the second arc unit (10b), and the third arc unit (10c) are extended in a straight line along the length (L1) direction.
[0036] In coupling pattern B5, the horizontal slot (13) of the third arc unit (10c) is first coupled to the coupling projection (21), and 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 coupled to the outside of it so as to face each other. At this time, the inclined half groove (11) and the horizontal half groove (12) may be positioned opposite each other.
[0037] When the arc units (10) are joined according to the joining pattern B5, the connection angle between the first arc unit (10a) and the second arc unit (10b) is determined based on the inclination angle of one of the inclined half-grooves (11). For example, if the angle of the inclined half-groove (11) is 30 degrees, the connection angle between the first arc unit (10a) and the second arc unit (10b) will be 150 degrees. In this way, the connection angle between the first arc unit (10a) and the second arc unit (10b) joined according to joining pattern B5 is wider than the connection angle according to joining patterns B1 and B2 by the inclination angle of the inclined half-groove (11).
[0038] Figure 8 illustrates a new form of flower-shaped mold in which joining patterns B1 and B5 are appropriately arranged. Thus, by appropriately arranging joining patterns B3, B4, or B5 in addition to joining patterns B1 and B2, the assembly set according to the present invention can produce molds of various shapes and sizes according to the user's creativity. The diameter of the mold increases as the arrangement of joining patterns B3, B4, or B5 increases compared to joining patterns B1 and B2.
[0039] On the other hand, Figure 9 shows how four circular objects of different diameters are constructed using the assembly set of the present invention. Specifically, in Figure 9, object C1 is constructed using 24 arc units (10) and 12 linker units (20), object C2 is constructed using 48 arc units (10) and 24 linker units (20), object C3 is constructed using 72 arc units (10) and 36 linker units (20), and object C4 is constructed using 96 arc units (10) and 48 linker units (20).
[0040] In the case of the conventional flat-plate assembly set shown in Figure 1, the length of the arc unit (100) and the angle of the inclined half-grooves (101) on both sides are fixed, so it is not possible to construct shapes other than arc shapes and circular shapes, such as those shown in Figures 7 and 8. Furthermore, it is not possible to construct circular shapes with different diameters, as shown in Figure 9.
[0041] Figure 10 shows an example of an application of the present invention, in which a light fixture is made using a circular object composed of the toy assembly set. [Explanation of Symbols]
