Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to architecture, exhibitions, and other decorative objects;
Alternatively, the present invention relates to a wave body device that can be used as a decorative ceiling, an advertisement display surface, a guide display surface, etc.

(Prior Art) Conventionally, in order to enhance the visual effect, a device has been provided that forcibly swings or rotates a ceiling, a portion of a wall surface, an advertisement display surface, etc. by driving a motor.

(Problems to be Solved by the Invention) The present invention differs from conventional drive systems that are directly connected to a motor, in that the swinging of one unit is linked to the swinging of another unit.
The present invention aims to provide a wave body device that has a series of wave motions as a whole and in which complex wave motions are generated depending on the shape of the constituent unit surfaces, and its use is not limited to conventional uses.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a plurality of units of suitable shapes that fit within a triangle, and each unit has three sides of the triangle or each of the three sides. The t-th unit is connected to each other via a rotating or bending axis corresponding to a part thereof, and each unit is supported by a telescopic support mechanism at each center of gravity position to form a wave body device. shall be.

In this case, in order to perpetuate the wave motion, a drive mechanism for rotating or bending the connecting portion of at least one adjacent unit is provided in the unit, or at least one unit support mechanism is expanded and contracted. It is preferable to arrange a drive mechanism, and each unit is supported from one side, for example, by hanging from above, by supporting from below, or by supporting from both sides. This can be done simultaneously from both sides, for example from above and below.

(Function) Since each unit is supported at its center of gravity, the surrounding area is in an unloaded state, so movement or fluctuation of at least one unit will sequentially affect each side of each unit from the entire periphery. They are linked together to produce various waves depending on the polygonal shape of the unit as a whole.

(Example) The present invention will be explained below by way of an example.

1 to 10 show examples in which the structural unit is an equilateral triangular plate, which is suspended and supported from above.

The plate 1 is made of an appropriate material such as synthetic resin, aluminum, or stainless steel, and has at least a lower surface with an appropriate finishing surface such as a material surface, a colored surface, a printed surface, or a mirror surface depending on the purpose of decoration or display, and at the same time, it has a flat surface. , or an appropriate surface shape such as a central concave surface, a convex surface, or an uneven surface (the figure shows a flat surface), and each side of the triangle has a tapered edge 2 whose upper edge is cut on one side at 45 degrees as shown in FIG.

Note that the ends of the plates may have arcuate edges instead of tapered edges, as long as adjacent plates can easily rotate or bend with respect to each other.

Further, as shown in FIG. 2, a hanging hook 3 is buried in the center of gravity on the upper side of the plate 1, and the plurality of plates are arranged in parallel so that the entire array has a desired shape (diamond shape in the figure).

A hinge 4 is fixed to an adjacent side of each of the plates arranged in parallel, spanning both plates. The structure of the hinge 4 is not limited as long as it has low rotational or bending resistance so that the swinging motion of the plate 1 is smoothly transmitted to the adjacent plate. The upper surfaces of both plates are bonded together, and an aluminum plate 4b is applied to the upper part of each plate and fixed with screws 4c. - The number of hinges provided on each side may be arbitrary, but it is preferable to provide two hinges on each side in order to maintain wave stability. Alternatively, the hinge may be formed so that adjacent plates are directly pivotally connected to each other along an axis parallel to the sides, instead of being configured to be fixed separately.

A support mechanism for suspending each plate 1 is constructed by connecting a predetermined length of cotton body 5 hanging from a structure (not shown) to a hook 3. Although the suspension is performed at least partially through the spring 6, the entire cotton body 5 may be made of a spring.

In addition, the above-mentioned support mechanism, as shown in FIG.
Hooks are fixed to three points or multiple points other than three points (not shown) that support the plate 1 with an equal load, and each cotton body 5b connected to each hook is gathered at one point, and then one cotton body 5a is attached. Alternatively, as shown in FIG. 5, the cotton body 5c connected to each of the plurality of hooks may be directly suspended from the structure. In this case, the cotton body 5a
.

5b may be provided with a spring, or both may be provided with a spring, and the cotton body 5c may be provided with a spring or may be provided with a spring.

According to the above configuration, when one plate 1 swings, at least two sides or two or more vertices of the triangle move up and down differently, and in conjunction with this, each adjacent plate swings, and each adjacent plate sequentially moves up and down in different ways. The plate oscillates, causing the entire plate to make complex wave motions. The smaller the number of supported hooks, the more sensitive the swinging, and the smaller the number of supporting points, the more sensitive the swinging becomes.

6 to 8 show examples in which a drive mechanism for generating wave motion is provided.

In FIG. 6, a tensioning device 7 is disposed on the upper surface of the adjacent plates at a position closer to or farther from each other than the center of gravity of both plates, and which periodically pulls and reduces the distance between the two plates. The tensioning device 7 may be an electromagnetic adsorption mechanism that is intermittently energized, may be a shape memory alloy that expands and contracts and is heated intermittently, or may be a reversible drive morph. , it may be a mechanism that combines these with gears, etc. (and any other mechanism may be adopted.

In FIG. 7, the hinge between adjacent plates is an electric hinge 8. For example, any mechanism may be adopted, such as using the hinge portion of one plate as the rotating shaft 8a serving as an electromagnetic core, and using the hinge portion of the other plate as a conductive rotating body fitted thereto.

FIG. 8 shows a drive mechanism disposed in the support mechanism.

Any mechanism may be adopted, such as suspending the cotton body 5 by a motor mechanism 9 that winds and unwinds it, or suspending it from a structure, or connecting the end of a near motor 10 to the middle part of a spring to move the spring up and down. Ru.

In the above embodiment, the plate 1 is suspended and supported from above, but as shown in FIG. Alternatively, as shown in FIG. 10, the cotton body 5 can be
2 and 5 f, etc., and in this case, both upper and lower surfaces or any one surface can be used as a finished surface for decoration or display.

Further, in the above embodiment, the structural unit body is shown as an equilateral triangular plate, but the unit body may be a polygonal plate, a net body, a rod-shaped body, etc., as long as the unit body has a shape that fits within a triangle that can be arranged in parallel with each other. Any other shape may be used, and in this case, the units are connected to each other via rotational or bending axes corresponding to three sides of a triangle or a portion of each of the three sides. Figure 11 shows a hexagonal plate 1 as an example.
FIG. 12 is an example of a rod-shaped body 1b having rotation shafts 4b corresponding to parts of each of the three sides of a triangle.

By setting the shape to fit within such a triangle, the wave motion as a whole can be performed extremely smoothly.

(Effects of the Invention) In this way, according to the present invention, structural units of any shape that fit within a triangle are successively arranged side by side so as to be freely rotatable or bendable, and each unit is supported in a flexible manner. Accordingly, it is possible to provide a wave body device in which each of the unit bodies swings in conjunction with each other to generate a unique wave motion as a whole, and its uses are expanded to various objects, ceilings, display surfaces, and more.

By providing a drive mechanism that rotates or bends the connecting portion of at least one adjacent unit, or a drive mechanism that expands and contracts at least one unit support mechanism, the wave motion is permanent and its effect can be maintained. Can be done. Moreover, by setting the support mechanism on a desired surface side, it can be used for applications that can accommodate viewing angles in multiple directions.
