Description

TECHNICAL FIELD [0001] The present invention relates to a decorative assembly and a decorative structure using the same,

The present invention relates to an ornamental assembly and a decorative structure using the ornamental assembly. More particularly, the present invention relates to a decorative ornamental assembly and a decorative structure using the ornamental assembly. More particularly, The present invention relates to an ornamental assembly and a decorative structure using the same, which can easily perform a disassembly operation and can be repeatedly used to reduce costs and prevent environmental pollution.

Generally, arched decorative structures are installed and widely used for store opening, event, discount, promotion, and the like.

These decorative structures are arched by hanging a large number of balloons on the support, so it is possible to produce the event place in a festive atmosphere, and it is expected to increase the sales and promote the effect. However, since the balloon should be fixed with air after each air injection, There is a drawback that it takes time.

In addition, when the time of about 3 to 4 days passes, the injected air is discharged. Therefore, it is necessary to remove the balloon and replace it with a new balloon. Since the balloon is easily damaged by a sharp tool, it can not be used for a long time.

In recent years, arch-shaped balloon-shaped articles such as those disclosed in Korean Registered Patent No. 10-0336117 (registered on Apr. 27, 2002) and Korean Registered Utility Model No. 20-0232133 (registered on May 15, 2001) Has been proposed.

1, a plurality of spherical balloons 2 are connected in a ring shape, and the connecting portion of the adjacent balloons 2 is connected to the inside of each balloons 2 by an air passage. And a rod 21 or a cord is inserted into the center of the plurality of unit balloons 1 to form a decorative body

The above-mentioned patent document 10-0336117 and the registration practice model 20-0232133 are advantageous in that each balloon is arranged in an orderly manner so that the decorative article is relatively simple and can be configured quickly. However, since the balloon is still used, When the time elapses, there is a disadvantage that it needs to be replaced according to the discharge of air and is easily damaged.

Also, Korean Patent No. 20-0464568 (Registered on Mar. 01, 2013) discloses an event balloon device as shown in Fig.

Korean Patent No. 20-0464568 discloses a light emitting module (20); A light emitting module according to any one of claims 1 to 3, further comprising: a transparent portion; a vertically connected portion at an inner central portion of the transparent portion; A balloon (10) comprising a diffusing portion to diffuse; An arch-shaped pole; A support table which is made up of a corrugated tube having one side opened in the longitudinal direction so that the pole is inserted therein and is inserted into the through holes of the balloons in which a plurality of the light emitting modules are stacked on the outer surface; A pedestal 40 for supporting both side portions of the pole; A power supply unit 60; Remote controller 80; And an operation controller 70 which is operated by the power supplied through the power supply unit and receives the control signal of the remote controller and controls the operation of the light emitting module in response to the received control signal.

As described above, the light emitting module 20 has the advantage of being able to induce the user's gaze and interest even in the night or in the dark, but the present invention is not limited to this, So that it needs to be replaced according to the discharge of air when a certain period of time has elapsed.

Meanwhile, since the conventional decorative structure as described above uses a balloon as a decoration member, it causes a fundamental problem such as an excessive assembly time and lack of durability. In addition, a separate air injection device is required to inject air into the balloon, There is a disadvantage that it is troublesome and inconvenient to use because the injection operation is required.

In addition, since the above-mentioned conventional decoration structure commonly requires replacing the balloon every predetermined time, there is a disadvantage that continuous maintenance is required. In addition, the balloon used once can not be reused and must be discarded, , And disadvantage of causing environmental pollution due to disposal.
