Description

Technology Field

[0001] The present invention relates to a prefabricated three-dimensional rotating decorative structure. Background Technology

[0003] Decorative structures can be used in various fields, such as interior decorations, lighting decorations, toy-type sculptures, and exhibition sculptures. Since these decorative structures have a shape in which multiple faces, corners, or frames are connected three-dimensionally, they can offer superior visual three-dimensionality and decorative qualities compared to simple flat decorations.

[0004] Conventionally, methods have been used to form three-dimensional decorative structures by folding paper, plastic sheets, or thin plates, or by assembling multiple rod-shaped members and vertex connecting members. For example, methods are known to form a polyhedron by interlocking multiple folding modules, or to form a decorative structure such as a regular dodecahedron by combining multiple side members and corner connecting members.

[0005] However, conventional three-dimensional decorative structures require the repetitive assembly of numerous individual parts, making the assembly process cumbersome, and as the number of joint positions between parts increases, assembly errors may accumulate. Additionally, if each face or each corner is formed as an individual part, the number of parts increases, and the manufacturing mold or processing process may become complex.

[0006] In particular, the method of forming a three-dimensional structure by individually connecting multiple frames presents the difficulty of having to align the connection positions and directions individually during the assembly process, as each frame must be joined at different directions and angles. Furthermore, due to the structural characteristic where the connection parts of each frame branch in multiple directions, the design of the mold for forming them becomes very complex, leading to increased mold manufacturing costs and reduced mass production capabilities. Moreover, with this method, it is difficult to ensure the shape precision of the structure after assembly is complete, and structural instability may occur during rotational driving due to the uneven connection strength between individual frames.

Specific details for implementing the invention

[0027] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0028] Hereinafter, the present invention will be described with reference to the drawings for explaining a prefabricated three-dimensional rotating decorative structure according to embodiments of the present invention.

[0029] The prefabricated three-dimensional rotating decorative structure according to the present invention includes a body (10), a three-dimensional structure (20), and a fixed part (30).

[0030] Referring to FIGS. 1 and FIGS. 2, first, the body (10) is made of a polyhedron. And the lower side of the body (10) can be supported on the ground.

[0031] The three-dimensional structure (20) is provided on the upper part of the body (10).

[0032] The fixing part (30) may include a first fixing member (31) coupled to the upper part of the three-dimensional structure (20) and a second fixing member (33) coupled to the lower part of the three-dimensional structure (20) and rotatably coupled to the body (10).

[0033] That is, the three-dimensional structure (20) may include a plurality of unit modules (21) that are made of the same shape and arranged and combined radially.

[0035] Below, the unit module (21) will be described in detail.

[0036] Referring to FIGS. 3 to 5, the unit module (21) is formed in a three-dimensional shape by connecting the first frame (21a) to the eleventh frame (21k) to each other.

[0037] These unit modules (21) include an upper triangular frame, a first middle triangular frame, a second middle triangular frame, and a lower triangular frame.

[0038] The upper triangular frame is formed by connecting both ends of the first frame (21a), the second frame (21b), and the third frame (21c), respectively.

[0039] The first intermediate triangular frame is formed by connecting one end of the fourth frame (21d) and the fifth frame (21e) to each end of the third frame (21c) of the upper triangular frame, and connecting the other ends of the fourth frame (21d) and the fifth frame (21e) to each other while facing downward.

[0040] The second intermediate triangular frame is formed by connecting one end of the sixth frame (21f) and the seventh frame (21g) to each end of the fifth frame (21e) of the first intermediate triangular frame, and connecting the other ends of the sixth frame (21f) and the seventh frame (21g) to each other while facing sideways.

[0041] The lower triangular frame is formed by connecting one end of the 8th frame (21h) and the 9th frame (21i) to each end of the 7th frame (21g) of the second intermediate triangular frame, respectively, and connecting the other ends of the 8th frame (21h) and the 9th frame (21i) to each other while facing downward.

[0042] That is, a plurality of unit modules (21) can form the outer shape of a three-dimensional structure (20) by connecting the upper connecting part of the upper triangular frame to the first fixing member (31) and connecting the lower connecting part of the lower triangular frame to the second fixing member (33).

[0043] At this time, since a plurality of unit modules (21) are made of the same shape and arranged radially, unit modules (21) can be mass-produced with only one type of mold, thereby reducing manufacturing costs and simplifying the assembly process.

[0044] Additionally, the unit module (21) may further include a 10th frame (21j), an 11th frame (21k), a first blade (22), a second blade (23), a first support blade (24), and a second support blade (25).

[0045] The 10th frame (21j) connects the upper triangular frame and the first intermediate triangular frame, and the 11th frame (21k) connects the second intermediate triangular frame and the lower triangular frame. By providing the 10th frame (21j) and the 11th frame (21k), the structural rigidity of the unit module (21) can be reinforced.

[0046] The first blade (22) is connected to the first frame (21a), the fourth frame (21d), and the tenth frame (21j), and the second blade (23) is connected to the fifth frame (21e), the eighth frame (21h), and the eleventh frame (21k).

[0047] The first blade (22) and the second blade (23) have one side formed in a concave shape, so that wind transmitted from the side is concentrated on the concave surface, thereby increasing drag and allowing the three-dimensional structure (20) to rotate in one direction.

[0048] For example, by arranging the concave surfaces of the first blade (22) and the second blade (23) to face the same direction, the three-dimensional structure (20) can rotate in a certain direction by the wind.

[0049] The first support blade (24) is connected to the third frame (21c) and the first blade (22) to support the first blade (22), and the second support blade (25) is connected to the seventh frame (21g) and the second blade (23) to support the second blade (23).

[0050] The first support blade (24) and the second support blade (25) can rotate the three-dimensional structure (20) by the wind transmitted from the upper and lower parts.

[0051] By providing the first support blade (24) and the second support blade (25), the deformation of the first blade (22) and the second blade (23) can be prevented and rotational stability can be improved.

[0052] Additionally, a coupling groove (26) is formed in each of the connecting portions formed at both ends of the fifth frame (21e). In the connecting portion where the ends of the first frame (21a), third frame (21c), and fourth frame (21d) are joined, and in the connecting portion where the ends of the sixth frame (21f), seventh frame (21g), and ninth frame (21i) are joined, a coupling projection (27) capable of being fitted into the coupling groove (26) is formed protrudingly.

[0053] For example, if five unit modules (21) are arranged radially and the connecting protrusions (27) of adjacent unit modules (21) are sequentially fitted into the connecting grooves (26), the connecting parts between the unit modules (21) can be mutually connected without a separate fastening member, thereby allowing the three-dimensional structure (20) to be assembled. By providing the connecting grooves (26) and connecting protrusions (27), the assembly of the unit modules (21) is simplified, and the effect of preventing movement in the connected state is achieved.

[0055] Here, a plurality of unit modules (21) arranged and combined in a radial manner are fixed at their upper and lower ends by a first fixing member (31) and a second fixing member (33).

[0056] The first fixing member (31) is formed in the shape of a circular disc, and on the upper surface, a plurality of first mounting grooves (32) are formed at equal intervals along the circumferential direction for the upper coupling part of the unit module (21) to be seated.

[0057] The first frame (21a) is formed in a half shape facing the second frame (21b) of the adjacent unit module (21), and by facing the second frame (21b) of the adjacent unit module (21), it forms a single bar-shaped frame and is seated in the first mounting groove (32).

[0058] Referring to FIGS. 3 and FIGS. 6, the second fixing member (33) is also formed in the shape of a circular disc, and on the upper surface, a plurality of second mounting grooves (34) are formed at equal intervals along the circumferential direction for the lower coupling part of the unit module (21) to be seated.

[0059] The 8th frame (21h) is formed in a half shape facing the 9th frame (21i) of the adjacent unit module (21), and by facing the 9th frame (21i) of the adjacent unit module (21), it forms a single bar-shaped frame and is seated in the 2nd mounting groove (34).

[0060] By providing the first fixing member (31) and the second fixing member (33), the effect is that a plurality of unit modules (21) can be firmly fixed in a radially aligned state.

[0061] Meanwhile, an axis coupling part connected to the rotation axis of the rotating part (40) to be described later is formed at the lower part of the second fixing member (33), so that the entire three-dimensional structure (20) can rotate by driving the rotating part (40).

[0063] Meanwhile, the prefabricated three-dimensional rotating decorative structure according to the present invention may further include a rotating part (40) and a control part (50).

[0064] Referring to FIG. 9, the rotating part (40) is provided inside the body (10) and is connected to the second fixing member (33) so as to rotate the second fixing member (33).

[0065] For example, the rotating part (40) may include a motor and a rotating shaft, and the rotating shaft may be coupled to the shaft coupling part of the second fixing member (33) to rotate the second fixing member (33) by driving the motor. By providing the rotating part (40), the three-dimensional structure (20) can actively rotate to enhance the visual decorative effect.

[0066] The control unit (50) can control the rotation unit (40).

[0067] Here, the prefabricated three-dimensional rotating decorative structure according to the present invention may further include an input unit (60) for inputting a control signal of the rotating part (40).

[0068] For example, the input section (60) may be composed of a button, but is not limited thereto.

[0069] And, by providing an input unit (60), there is an effect that the user can control the rotation of the three-dimensional structure (20) at a time they want.

[0072] Meanwhile, the above-described body (10) may include a base part (11), a split frame (12), and a door part (13).

[0073] Referring to FIG. 2, the base portion (11) forms the lower side of the body (10) and can be supported on the ground.

[0074] The split frame (12) protrudes upward from the base part (11) to divide the interior of the body (10) into multiple internal spaces (17), and an opening is formed on one side of each internal space (17).

[0075] For example, the split frame (12) can divide the interior of the body (10) into four interior spaces (17), but the number may vary depending on the number of sides of the body (10) and is not limited thereto.

[0076] Sliding grooves (15) are formed along the length of both sides of the split frame (12), so that the door part (13) can be joined in a sliding manner.

[0077] Referring to FIGS. 7 and 8, the door portion (13) is slidably coupled to the sliding groove (15) of the split frame (12) to enable the opening of the internal space (17) to be opened and closed.

[0078] The door portion (13) is made of a light-transmitting translucent material, so that the interior is not visible when the lighting portion (16) is not turned on in the interior space (17), but when the lighting portion (16) is turned on, the shape formed on the outer surface of the door portion (13) can be reflected in the form of a shadow by the light. By providing the door portion (13), there is an effect of providing a decorative effect in which the visual effect changes depending on whether the lighting portion (16) is turned on.

[0079] Additionally, a locking projection (14) is formed on the upper part of the door portion (13), and a locking groove corresponding to the locking projection (14) is formed on the split frame (12), so that the door portion (13) can be fixed by the locking projection (14) being engaged with the locking groove while the door portion (13) is slidably connected.

[0080] By providing a locking projection (14) and a locking groove, the door part (13) can be firmly fixed without movement after sliding connection.

[0081] Meanwhile, the prefabricated three-dimensional rotating decorative structure according to the present invention may further include a lighting unit (16) provided in the internal space (17).

[0082] The lighting unit (16) may include an LED independently provided on the floor of each internal space (17), and the control unit (50) may control the lighting unit (16) to be lit in one or more internal spaces (17).

[0083] By providing a lighting unit (16), each internal space (17) can be independently controlled to light up, thereby enabling various lighting effects.

[0084] Sliding grooves (15) are formed longitudinally on both sides of the door portion (13), and the body (10) may further include a decorative panel that is fitted into the sliding grooves (15).

[0085] The sliding groove (15) is formed in a shape that becomes narrower towards the top. As the decorative panel is inserted into the sliding groove (15), the decorative panel can be automatically fixed by a wedge action. For example, when the decorative panel is inserted from the bottom to the top of the sliding groove (15), as the width of the sliding groove (15) narrows, both sides of the decorative panel come into close contact with the sliding groove (15), so that the decorative panel can be firmly fixed without a separate fastening member.

[0086] By forming the sliding groove (15) in a shape that narrows toward the top, the decorative panel can be easily removed and replaced, while preventing movement in the fixed state.

[0087] Since the decorative panel is connected to the inner side of the frame of the door part (13) in a sliding manner so that it can be inserted and removed and replaced, various visual effects can be achieved by replacing the decorative panel with one printed with various shapes.

[0088] The door part (13) is made of a light-transmitting translucent material so that when the lighting part (16) is turned on, the shape already formed on the decorative panel can be projected as a shadow on the outer surface by the light.

[0089] For example, if a shape such as a star, moon, or flower is printed on the decorative panel, when the lighting unit (16) is turned on, the shape is projected as a shadow onto the outer surface of the door unit (13), thereby enhancing the decorative effect.

[0090] By providing a door section (13) and a decorative panel, various visual effects can be achieved depending on whether the lighting section (16) is turned on and whether the decorative panel is replaced.

[0092] The operation sequence of the prefabricated three-dimensional rotating decorative structure according to the present invention will be described below.

[0093] When the user operates the input unit (60) once, the control unit (50) lights up the lighting unit (16) provided in one internal space (17) and drives the rotation unit (40) at a low speed to rotate the three-dimensional structure (20) at a low speed. When the user operates the input unit (60) twice, the control unit (50) lights up the lighting unit (16) provided in two internal spaces (17) and drives the rotation unit (40) at a medium-low speed. When the user operates the input unit (60) three times, the control unit (50) lights up the lighting unit (16) provided in three internal spaces (17) and drives the rotation unit (40) at a medium-high speed. When the user operates the input unit (60) four times, the control unit (50) lights up all the lighting units (16) provided in four internal spaces (17) and drives the rotation unit (40) at a high speed. When the input unit (60) is operated 5 times, the control unit (50) turns off all lighting units (16) and stops the operation of the rotating unit (40). In this way, the number of lighting units (16) and the rotation speed of the rotating unit (40) increase stepwise according to the number of operations of the input unit (60), so that the user can select the desired effect.

[0095] The body (10) may further include a reflective section. The reflective section is provided on the side of the dividing frame (12) that forms an internal space (17), so that light emitted when the lighting section (16) is turned on is directed toward the decorative panel.

[0096] For example, the reflective part may be made of a reflective film or reflective coating capable of reflecting light, but is not limited thereto.

[0097] By providing a reflector, the light emitted from the lighting unit (16) is not dispersed but concentrated toward the decorative panel, so that the shape formed on the decorative panel can be reflected more clearly on the outer surface of the door unit (13).

[0100] Meanwhile, multiple unit modules (21) can be molded in different colors. For example, if five unit modules (21) are molded in red, blue, yellow, green, and white respectively, a visual effect in which the colors change continuously can be produced when the three-dimensional structure (20) rotates. By molding the unit modules (21) in different colors, there is an effect that a color change effect due to rotation can be provided without separate lighting.

[0101] The first blade (22) and the second blade (23) may further include an angle adjustment unit that enables the angle of the concave surface to be adjusted. By changing the angle of the concave surface of the first blade (22) and the second blade (23), the angle adjustment unit can mechanically control the rotational speed of the three-dimensional structure (20) by adjusting the magnitude of the drag force caused by the wind. For example, if the angle of the concave surface is increased, the drag force increases and the rotational speed increases, and if the angle of the concave surface is decreased, the drag force decreases and the rotational speed decreases. By providing the angle adjustment unit, the rotational speed can be controlled solely by adjusting the angle of the blade without changing the output of the motor.

[0102] The lighting unit (16) may be composed of RGB LEDs. The control unit (50) controls the color of the lighting unit (16) to change in stages according to the number of operations of the input unit (60), and may link the rotation speed stage of the rotation unit (40) with the color change of the lighting unit (16). For example, when the input unit (60) is operated once, the lighting unit (16) lights up in red and rotates at a low speed; when operated twice, it changes to blue and rotates at a medium-low speed; when operated three times, it changes to green and rotates at a medium-high speed; and when operated four times, it changes to white and rotates at a high speed. By providing RGB LEDs, the rotation speed and lighting color are linked, which has the effect of enabling colorful visual effects.

[0103] The reflective portion may be provided at an angle on the side of the split frame (12). By providing the reflective portion at an angle, the light emitted from the lighting portion (16) is concentrated toward the decorative panel, so that the shape formed on the decorative panel can be reflected more clearly on the outer surface of the door portion (13).

[0104] The input unit (60) may consist of at least one of a button, a wireless remote control, and a smartphone app, but is not limited thereto. The control unit (50) may further include a wireless receiver that receives a wireless signal, and can control the rotation unit (40) and the lighting unit (16) according to a control signal transmitted from a wireless remote control or a smartphone app. By providing a wireless receiver, the user can control the rotation and lighting of the three-dimensional structure (20) even from a distance.

[0105] The prefabricated three-dimensional rotating decorative structure according to the present invention may further include an acoustic detection unit. The acoustic detection unit detects an external acoustic signal, and the control unit (50) can automatically change the lighting and extinguishing of the lighting unit (16) and the rotation speed of the rotating unit (40) according to the beat of the acoustic signal detected by the acoustic detection unit. For example, the faster the beat of the music, the faster the lighting and extinguishing of the lighting unit (16) is repeated and the rotation speed of the rotating unit (40) increases, and the slower the beat, the longer the repetition cycle of lighting and extinguishing becomes and the slower the rotation speed may decrease. By providing an acoustic detection unit, there is an effect in that lighting and rotation are automatically produced in accordance with the music without separate operation.

[0107] Meanwhile, the unit module (21) can be molded from a luminescent material. For example, if the unit module (21) is molded from a plastic resin mixed with a luminescent pigment, the luminescent material absorbs light energy while the lighting unit (16) is lit, and even after the lighting unit (16) is turned off, the absorbed energy is gradually released to produce a residual light effect. By molding the unit module (21) from a luminescent material, there is an effect of providing a visual effect in which the three-dimensional structure (20) emits light regardless of whether the lighting unit (16) is lit.

[0108] The unit module (21) may be molded with a portion of a luminous material and the remainder of a transparent material. For example, if the unit module (21) is molded with transparent acrylic or transparent polycarbonate resin, light emitted from the lighting unit (16) can pass through the unit module (21) and be emitted to the outside. By molding the unit module (21) with a transparent material, the lighting effect inside the three-dimensional structure (20) is directly emitted to the outside, which has the effect of enabling a more spectacular visual presentation.

[0109] The prefabricated three-dimensional rotating decorative structure according to the present invention may further include a timer unit. The timer unit can automatically turn off the lighting unit (16) and automatically stop the operation of the rotating unit (40) after a certain period of time has elapsed. For example, if a user sets the timer unit to 30 minutes before going to sleep, the lighting unit (16) can be automatically turned off and the operation of the rotating unit (40) can be stopped after 30 minutes have elapsed. By providing a timer unit, the device can be automatically stopped without the user having to separately cut off the power, thereby saving energy.

[0110] The prefabricated three-dimensional rotating decorative structure according to the present invention may further include an illuminance detection unit. The illuminance detection unit detects ambient illuminance, and the control unit (50) can automatically turn on the lighting unit (16) and automatically start the operation of the rotating unit (40) if the illuminance value detected by the illuminance detection unit is less than or equal to a preset reference value. For example, when indoor lighting is turned off and the surroundings become dark, the illuminance detection unit detects this, the lighting unit (16) is automatically turned on, and the three-dimensional structure (20) starts rotating, so that it can be used as a night light or a mood light. By providing an illuminance detection unit, there is an effect of providing convenience in that the device operates automatically according to ambient brightness without separate operation.

[0111] The prefabricated three-dimensional rotating decorative structure according to the present invention may further include a vibration detection unit. The vibration detection unit detects external shock or vibration, and the control unit (50) can turn on the lighting unit (16) and start the operation of the rotating unit (40) when a vibration signal is detected from the vibration detection unit. For example, if a user claps their hands or taps a table, the vibration detection unit detects this, the lighting unit (16) turns on, and the three-dimensional structure (20) can start rotating. By providing a vibration detection unit, there is an effect that the device can be operated with simple movements without the need for separate button operation.

[0112] In addition to the coupling groove (26) and coupling projection (27), a locking projection and a locking groove may be further formed in the connection portion between adjacent unit modules (21). The locking projection is formed protruding from the connection portion of one unit module (21), and the locking groove is formed to be inserted into the connection portion of the adjacent unit module (21) in correspondence with the locking projection. For example, after the coupling groove (26) and the coupling projection (27) are fitted together, if the locking projection is inserted into the locking groove and rotated, the connection portion between the unit modules (21) can be fixed in a locked state. By providing the locking projection and the locking groove, the unit module (21) does not detach even during high-speed rotation of the three-dimensional structure (20), thereby ensuring safety.

[0113] The cross-sections of the first frame (21a) to the eleventh frame (21k) can be formed in a streamlined shape. For example, if the cross-section of each frame is formed in an airfoil shape similar to the cross-section of an aircraft wing, lift is generated and air resistance is reduced due to the pressure difference between the upper and lower surfaces of the frame when the three-dimensional structure (20) rotates. By forming the frame with a streamlined cross-section, faster rotation is possible with the same motor output, and rotational noise is reduced.

[0114] The first fixing member (31) can be detachably coupled to the body (10). For example, if a screw coupling or one-touch coupling structure is applied to the coupling portion between the first fixing member (31) and the body (10), the unit module (21) can be easily assembled and disassembled in an upward direction by separating the first fixing member (31) from the body (10). By making the first fixing member (31) detachable, the unit module (21) has the effect of being easy to replace and maintain.

[0115] The body (10) can be formed with a structure that can be stacked vertically. For example, by forming a connecting projection (27) and a connecting groove (26) on the upper and lower surfaces of the body (10), respectively, the internal space (17) can be expanded by connecting multiple bodies (10) vertically. By forming the body (10) with a stackable structure, the number of internal spaces (17) can be increased, allowing for more lighting units (16) to be provided and enabling various lighting effects.

Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of the present invention.
