Description

Da Vinci Bridge Toy Assembly Set

[0001] The present invention relates to a Da Vinci Bridge toy assembly set, and more specifically, to a toy assembly set comprising a plurality of flat-plate arc units (10) each having an inclined semi-groove (11) and a horizontal semi-groove (12) on each of the short sides and a horizontal slot (13) penetrating through the center, and a plurality of flat-plate linker units (20) each having a connecting protrusion (21) provided on each of the short sides, and wherein the inclined semi-groove (11), the horizontal semi-groove (12) and the horizontal slot (13) of the arc units (10) are alternately connected to the connecting protrusion (21) of the linker units (20) to form various shapes such as the Da Vinci Bridge.

[0002]

[0003] The Da Vinci bridge refers to an assembly method that builds an arch-shaped or circular structure by mutually supporting flat or bar-shaped assembly units without using nails, strings, or adhesives, or a sculpture built in this way.

[0004] The Da Vinci Bridge sculpture utilizes the structural mechanics principles of force distribution and mutual support, and has the advantage of being quick and easy to assemble and disassemble, so it is used in a variety of ways, not only for industrial purposes such as modular structures, tunnels, and military bridges, but also as educational materials and toys for students.

[0005] For example, Korean Patent Publication No. 10-2023-0043494 (March 31, 2023) introduces a canopy structure in which a first upright unit, a second upright unit, and a connecting unit connecting them are assembled in a Da Vinci bridge structure.

[0006] Additionally, numerous educational materials and toy assembly sets utilizing the Da Vinci Bridge are posted on Internet sites. Attached Figures 1 and 2 illustrate toys utilizing flat-plate assembly units among the Da Vinci Bridge assembly sets previously introduced on the Internet.

[0007] The above Da Vinci Bridge toy is composed of three types of assembly units, namely, a plurality of arc units (100) that form an arc on each side of the structure, a linker unit (200) that connects the arc units (100) on both sides, and a finishing unit (300) that supports the arc units (100) and finishes the arc shape.

[0008] Each of the short sides of the above arc unit (100) and one side of the finishing unit (300) is provided with an inclined groove (101, 301), and a horizontal slot (102, 302) is provided in the center thereof.

[0009] Additionally, a connecting projection (201) is protruded from each of the short sides of the linker unit (200).

[0010] Therefore, an arc-shaped structure as shown in Fig. 1 is produced by sequentially and alternately combining the inclined semi-groove (101) and horizontal slot (102) of the arc unit (100) with the connecting protrusion (201) of the linker unit (200). At this time, the arc radius of the structure is determined by the length of the arc member (100) and the angle of the inclined semi-groove (101) on both sides.

[0012] [Patent Document]

[0013] (Patent Document 1) Publication No. 10-2023-0043494 (March 31, 2023)

[0014]

[0015] As shown in the attached drawing 1, the Da Vinci Bridge assembly toy is very suitable for use as a learning material or toy for students because it uses a flat assembly unit made of, for example, MDF material.

[0016] However, since the length of the arc member (100) and the angle of the inclined groove (101) of the conventional Da Vinci bridge assembly unit are fixed, the shape and size of the object that can be manufactured through this assembly unit are very limited, and therefore, there are limits to the user's ability to exercise his or her creativity.

[0017] Accordingly, the problem that the present invention seeks to solve is to provide a Da Vinci Bridge toy assembly set that can produce sculptures of various shapes and sizes based on the Da Vinci Bridge structure according to the user's creativity.

[0018]

[0019] The Da Vinci Bridge assembly set according to the present invention is:

[0020] A flat plate structure extended in the direction of length (L1), each of the short sides having an inclined groove (11) arranged obliquely with respect to the direction of length (L1) and a horizontal groove (12) arranged parallel to the direction of length (L1), and a plurality of arc units (10) having a horizontal slot (13) arranged parallel to the direction of length (L1) penetrating through the center;

[0021] A flat plate structure extended in the length (L2) direction, and a plurality of linker units (20) having a connecting projection (21) formed on each of the short sides by combining the inclined groove (11), horizontal groove (12) and horizontal slot (13) to form a Da Vinci bridge structure;

[0022] It is characterized by being composed of including.

[0023] The above linker unit (20) is characterized by a structure in which the horizontal semi-groove (12) of the first arc unit (10a) and the horizontal semi-groove (12) of the second arc unit (10b) are joined to face each other in the joining projection (21).

[0024] The above linker unit (20) is characterized by a structure in which the inclined groove (11) of the first arc unit (10a) and the horizontal groove (12) of the second arc unit (10b) are coupled to face each other in the connecting projection (21).

[0025]

[0026] The Da Vinci Bridge assembly set according to the present invention can form arch-shaped or circular structures with different diameters, and further has the effect of being able to produce structures in various shapes, such as heart shapes or flower shapes, depending on the user's creativity.

[0038]

[0039] Hereinafter, the present invention will be described in detail using the attached drawings. However, since the attached drawings illustrate preferred embodiments of the present invention, the scope of the present invention is not limited by these embodiments.

[0040] Even if it is a configuration that is absolutely necessary for carrying out the present invention, a detailed description is omitted for matters that are introduced in the prior art or that can be easily carried out by a person skilled in the art from known technology.

[0041] And 'including' a component means that in addition to the specified component, other components can be included as needed. Also, in a rectangular component, the relatively narrow side is called the 'vertical width (Wa)', and the wider side is called the 'horizontal width (Wb)'.

[0042] The Da Vinci Bridge toy assembly set according to the present invention comprises a plurality of flat-plate arc units (10) and a plurality of flat-plate linker units (20). The arc units (10) and linker units (20) preferably have the same thickness (T1, T2), and may be provided for use by separating them along a cutting line provided on a board made of MDF, hardboard, or compressed Styrofoam, as shown in FIG. 3, or may be provided as separately injection-molded plastic products.

[0043] First, the arc unit (10) is a flat plate structure that extends in the length (L1) direction and has a predetermined thickness (T1), as shown in the attached drawing 4, and is provided with an inclined groove (11) and a horizontal groove (12) on each of the short sides. The inclined groove (11) and the horizontal groove (12) each have a structure that is open to the outside along the border line of the arc unit (10).

[0044] The above-mentioned inclined groove (11) is arranged obliquely so as to have a predetermined angle with respect to the length (L1) direction of the arc unit (10), and the above-mentioned horizontal groove (12) is arranged horizontally parallel to the length (L1) direction of the arc unit (10). The angle of inclination of the inclined groove (11), i.e., the angle between the inclined groove (11) and the horizontal groove (12), is approximately 20 to 40 degrees, and the preferable angle of inclination is 30 degrees.

[0045] In addition, a horizontal slot (13) is formed through the center of the arc unit (10) and is parallel to the length (L1) of the arc unit (10). The horizontal slot (13) has a closed structure inside the arc unit (10). In each arc unit (10), two inclined semi-grooves (11), two horizontal semi-grooves (12), and one horizontal slot (13) are arranged symmetrically on the left and right.

[0046] Next, the linker unit (20) is a flat plate structure that extends in the length (L2) direction and has a predetermined thickness (T2) as shown in Fig. 5, and a connecting projection (21) is provided on each of the short sides. It is preferable that the connecting projection (21) has a left-right symmetrical structure, and as shown in Fig. 6, the inclined semi-groove (11), the horizontal semi-groove (12), and the horizontal slot (13) of the arc unit (10) are alternately connected to form a Da Vinci bridge structure.

[0047] At this time, it is preferable that the vertical widths (Wa1, Wa2, Wa3) of the inclined groove (11), horizontal groove (12), and horizontal slot (13) of the arc unit (10) are the same as the thickness (T2) of the joining projection (21) of the linker unit (20). Therefore, the inclined groove (11), horizontal groove (12), and horizontal slot (13) are each firmly joined to the joining projection (21) of the linker unit (20).

[0048] In addition, it is preferable that the horizontal widths (Wb1, Wb2) of the inclined groove (11) and horizontal groove (12) are each less than half the horizontal width (Wb4) of the connecting projection (21). Thus, two inclined grooves (11) or two horizontal grooves (12) can be connected to one connecting projection (21) so as to face each other on both sides.

[0049] Fig. 6 shows an example of use of an assembly set according to the present invention, and shows joining patterns B1 and B2 in which three arc units (10a, 10b, 10c) are assembled by interlocking with the joining projection (21) of the linker unit (20). First, joining pattern B1 is such that the horizontal slot (13) of the third arc unit (10c) is joined to the inner side of the joining projection (21), and the right slanted groove (11) of the first arc unit (10a) and the left slanted groove (11) of the second arc unit (10b) are joined to face each other on the outer side thereof.

[0050] And the coupling pattern B2 is formed by coupling the right-hand inclined groove (11) of the first arc unit (10a) and the left-hand inclined groove (11) of the second arc unit (10b) to the coupling protrusion (21) so that they face each other, and the horizontal slot (13) of the third arc unit (10c) is coupled to the outside thereof. That is, the two inclined grooves (11) of the arc unit (10) are each involved in two different coupling patterns B1, and the horizontal slot (13) is involved in the coupling pattern B2.

[0051] When the arc units (10) are combined according to the above-described combination patterns B1 and B2, the connection angle between the first arc unit (10a) and the second arc unit (10b) is determined by the inclination angles of the inclined semi-grooves (11) on both sides. For example, if the angle of the inclined semi-grooves (11) is 30 degrees, the connection angle between the first arc unit (10a) and the second arc unit (10b) becomes 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 semi-grooves (11).

[0052] In this way, when the arc units (10) are continuously connected so that the connection patterns B1 and B2 are alternately arranged once each on the connecting protrusions (21) on both sides of the linker unit (20), an arch-shaped Da Vinci bridge structure as shown in Fig. 6 is formed. At this time, the specifications of the arch-shaped structure are determined according to the length (L1) of the arc unit (10) and the angle of the inclined groove (11).

[0053] In addition, in order to firmly maintain the above-mentioned joining pattern B1 and joining pattern B2, it is preferable that the horizontal width (Wb4) of the joining protrusion (21) is the same as the horizontal width (Wb3) of the horizontal slot (13), and it is preferable that the vertical width (Wa4) of the joining protrusion (21) is larger than twice the thickness (T1) of the arc unit (10).

[0054] Meanwhile, the attached drawing 7 shows the joining patterns B3, B4 and B5 using the horizontal groove (12), which is a feature of the present invention. In the joining pattern B3, the horizontal slot (13) of the third arc unit (10c) is first joined to the joining projection (21) of the linker unit (20), and on the outside thereof, the right horizontal groove (12) of the first arc unit (10a) and the left horizontal groove (12) of the second arc unit (10b) are joined in parallel so as to face each other.

[0055] And in the joining pattern B4, the right horizontal semi-groove (12) of the first arc unit (10a) and the left horizontal semi-groove (12) of the second arc unit (10b) are 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 thereof. When the arc units (10) are joined according to the joining patterns B3 and B4, the first arc unit (10a), the second arc unit (10b), and the third arc unit (10c) extend in a straight line along the length (L1).

[0056] In the final joining pattern B5, the horizontal slot (13) of the third arc unit (10c) is first joined to the joining protrusion (21), and then the horizontal semi-groove (12) of the first arc unit (10a) and the inclined semi-groove (11) of the second arc unit (10b) are joined to the outside thereof so as to face each other. At this time, the inclined semi-groove (11) and the horizontal semi-groove (12) may be arranged in opposite left and right positions.

[0057] When the arc units (10) are joined according to the above-described joining pattern B5, the connecting angle between the first arc unit (10a) and the second arc unit (10b) is determined by the inclination angle of one inclined groove (11). For example, if the angle of the inclined groove (11) is 30 degrees, the connecting angle between the first arc unit (10a) and the second arc unit (10b) becomes 150 degrees. In this way, the connecting angle between the first arc unit (10a) and the second arc unit (10b) joined according to the joining pattern B5 is wider by the inclination angle of the inclined groove (11) than the connecting angle by the joining patterns B1 and B2.

[0058] Attached Figure 8 illustrates a novel flower-shaped sculpture in which the joining patterns B1 and B5 are appropriately arranged. In this way, the assembly set according to the present invention can produce sculptures of various shapes and sizes according to the user's creativity by appropriately arranging the joining patterns B3, B4, or B5 in addition to the joining patterns B1 and B2. As the arrangement of the joining patterns B3, B4, or B5 increases compared to the joining patterns B1 and B2, the diameter of the sculpture increases.

[0059] Meanwhile, Fig. 9 shows a configuration of four circular shapes with different diameters using the assembly set of the present invention. Specifically, in Fig. 9, shape C1 is configured using 24 arc units (10) and 12 linker units (20), shape C2 is configured using 48 arc units (10) and 24 linker units (20), shape C3 is configured using 72 arc units (10) and 36 linker units (20), and shape C4 is configured using 96 arc units (10) and 48 linker units (20).

[0060] For reference, in the case of a conventional flat assembly set such as that of Fig. 1, since the length of the arc member (100) and the angle of the inclined grooves (101) on both sides are fixed, it is impossible to construct a shape such as that of Fig. 7 or Fig. 8 other than an arch or circular shape. In addition, it is also impossible to construct a circular shape with different diameters as in Fig. 9.

[0061] Lastly, Fig. 10 is an example of an application of the present invention, showing a lighting fixture manufactured using a circular shape made up of the toy assembly set.
