Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is a front view showing a basic configuration of an interior decoration apparatus of the present invention.

The interior decoration device according to the present invention can be manufactured in various shapes and forms to provide an interior function. Basically, the interior decoration device according to the present invention can be configured to be manually operated by a user, But may be utilized as a play toy that can be played by a user, especially a child.

In order to facilitate understanding based on this reason, the interior decoration device of the present invention is expressed in the form of a toy in the drawings shown below.

Of course, the interior decoration apparatus of the present invention is not limited to such a toy type, but can be modified into various forms within the scope of the technical idea of the present invention.

1 and 2, the interior decoration apparatus according to the present invention includes a base 10 supported on the floor, at least one supporter 20 rising up from one side of the base 10, a supporter 20, A core 30 rotatably connected to a shaft 25 extending inwardly from the upper side of the core 30 and at least one chamber 40 connected to the core 30 via a connection path 50. [ .

The base 10 has a weight enough to safely support the load of the structure of the core 30 and the chamber 40 to be described later, And basically provides a function of allowing the apparatus of the present invention to be fixedly supported without floating on a floor surface (a flat upper surface of a desk, a decorative table, etc.).

The base 10 may further include a controller 100, an illumination lamp 80, a motor 71, etc., which will be described later.

The supporter 20 extends upward at least from one side of the base 10 and extends upwardly from the upper portion of the base 10 as shown in the drawing, So that the core 30 and the chamber 40 to be described later can be located in a space provided in the upper portion of the base 10. [

The supporter 20 may be extended from the side of the base 10 to one side so that the core 30 and the chamber 40 can be securely supported while ensuring smooth rotation of the core 30. [ It is more preferable that the pair of supporters 20 extend from the left and right sides of the base 10 as shown in Figs.

A shaft 25 extends from the upper end of the supporter 20 toward the inner side (toward the core), and the core 30 is rotatably coupled to the shaft 25. Although not shown in the drawing, a handle connected to the shaft 25 is formed on the opposite side of the shaft 25, that is, on the upper side of the upper end of the supporter 25 so that the shaft 25 is also rotated as the user rotates the handle It is possible.

The core 30 has a three-dimensional structure having a space in which the other part except the connection path 50 connected to the chamber 40 to be described later is hermetically sealed and the liquid 60 can be filled therein And is shown in the form of a sphere in the drawing, but it is not limited thereto and may have various shapes.

As described above, the inner space of the core 30 is filled with the liquid 60. The liquid 60 may be the most representative of water, but may be colored (for example, liquid blue) by pigments or the like, and a plurality of vinyl colored or fluorescent materials may be added to the liquid 60).

It is important to note that the liquid 60 is connected to the core 30 and the interconnecting path 50 in a smaller amount than the volume of the chamber 40 (i.e., not filled to fill the core and chamber) 30 and the chamber 40, and the presence of this air leads to the bubble generation principle to be described later.

In addition, since the shaft 25 of the supporter 20 acts as a hinge, the core 30 connected to the core 30 can be rotated by the external force The chamber 40, which will be described later, connected to the core 30 while being rotated by the user (such as rotating the shaft) can also be rotated.

The core 30 is made of a transparent or translucent material so that the user can visually confirm the presence of the liquid 60 therein. The core 30 may be made of a flexible material such as rubber, as well as hard and stretchable.

The chamber 40 has a three-dimensional structure having a space for accommodating the liquid 60 inside the chamber 40, except for the connecting path, 50 in one piece with the one side of the core 30.

In order to achieve the visual fun of bubble generation and the structural balance of the interior decorating apparatus according to the present invention, two chambers 40 may be formed at an angle of 180 degrees with each other as shown in the figure, It is also possible to form three pieces at an angle of 120 degrees with each other or four pieces at right angles to each other.

In addition, in order to visually express the merits of bubbling, the chamber 40, like the dolphin shape shown in the drawings, preferably has a portion where the connecting path is connected and a distance between the opposite sides of the chamber 40 is relatively longer than other side lengths.

The chamber 40 is made of a transparent or semi-transparent material so that the inside of the chamber 40 can be visually recognized. The chamber 40 is made of rubber-like soft material and can be expanded or contracted according to the movement of the liquid 60.

In the figure, the chamber 40 is formed in the shape of a dolphin, and the core 30 is formed in a ball shape to be handled by the dolphin, so as to give design integrity to each other and to have a play toy shape. When the apparatus of the present invention is utilized as a toy, the core 30 and the chamber 40 are formed into an animal shape, a character shape, and the like. It can be integrally formed as a combination of various shapes according to purposes.

The connection path 50 connects the core 30 and the chamber 40 to serve as a pipe through which the liquid 60 moves and supports the chamber 40 on the basis of the core 30 connected to the supporter 20. [ . However, in order to smooth bubble generation, it is preferable that it is composed of 2 to 5 pieces, and in the drawings, three pieces are exemplarily shown.

 Particularly, when a plurality of connection paths 50 are formed, the diameters and extension lengths of the connection paths 50 may be different depending on the liquid amount, the length of the chamber, the viscosity of the liquid, and the like.

The operation of the interior decoration apparatus according to the present invention will now be described.

2 is a view showing an exemplary rotation state of the interior decorating device of the present invention.

As can be seen from FIG. 2, when the two chambers 40 are positioned one at a time and at an angle of 180 with respect to each other, the chamber 40, which is located at the lower side by gravity, The liquid 60 stored in the reservoir 30 is filled.

In this state, air exists in the upper surface of the water surface, that is, the upper space of the chamber 40 located on the lower side or the upper space of the core 30, depending on the liquid amount.

Here, when the user rotates the handle or grasps the chamber 40 and directly rotates the chamber 40, the chamber 40 located at the lower side in FIG. Moves along the connection path in the direction of the upper, i.e., upper chamber.

In other words, the air in the core 30 is received into the upper chamber 40 through a simple process by which the user rotates the chamber 40.

When the chamber 40 is rotated to the original position, that is, to the lower position, the liquid 60 is supplied to the corresponding chamber (not shown) through the connection path 50 by atmospheric pressure or water pressure 40 and pushes air lighter than the liquid 60 through the connection path 50. As a result, the air contained in the chamber 40 escapes to the connection path 50. In particular, And is moved up in the chamber 40 through the connection path 50 in the core direction or in the core upward direction in a bubble form.

When the air is exhausted through the connection path 50 in the chamber 40, the phenomenon of rising air bubbles also ends. If the process of repeating this process is repeated, the process of rotating the chamber 40 is repeated In the apparatus of the present invention shown in the drawings, bubbles may alternately occur in the two chambers 40 during rotation of the up-down chamber 40 because two chambers 40 exist.

In addition, when the core 30 and the chamber 40 are made of a soft material such as rubber while the amount of air in the core 30 and the chamber 40 is controlled to be small, (30) and the chamber (40) can be stretched or shrunk, thereby providing additional visual enjoyment of the user.

As mentioned above, the bubbles may occur in the inner space of the core or the inner space of the chamber depending on the amount of liquid filled in the apparatus of the present invention.

In particular, even when the number of the connection paths 50 is one, air bubbles may be generated by controlling the rotation speed of the chamber 40 or by controlling the diameter of the connection path 50. However, 50, the entirety of the connection path 50 is filled with the liquid 60, so that the child of the air is not smooth and the generation of air bubbles due to the air movement phenomenon may not be visually evident. (50), and the air is concentrated in the specific connection path (50) so that the air flows in the form of bubbles .

This bubbling principle is based on the difference in density between the liquid 60 and the air, and the principle of gravity due to the drop of the liquid 60 and the air, and more specific bubbling principles can be supplemented by referring to known methods.

Through this process, the visual phenomenon in which the bubbles rise in the core 30 or the chamber 40 can be visually confirmed according to the operation for the rotation of the chamber of the user himself / herself, And can provide a variety of fun as a child's playground or toy.
