BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dome-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a play facility, and more particularly, to a domed play device including an air injection device capable of safely performing various movements such as jumping and having a structure that is easy to maintain.

A trampoline, often used for gymnastics or play, refers to a gymnastic game in which the player jumps or jumps on a resilient square mat with a spring, or an apparatus used in the game.

These trampolines have been used as exercise equipment for jumping by using the elasticity of mats and springs, but they have also been popularly used as a playground equipment because they have a more stimulating effect on the growth plate as well as a more interesting exercise for children. Recently, it has also been used for exercise for adult dieting.

However, since such a trampoline is installed in a state in which the mat hangs in the air hanging on an aggregate or an iron material, there is a problem that a user often accidentally attaches or falls down with the spring. For this purpose, a safety net is installed at the edge of the trampoline, but it is not a fundamental accident prevention measure. In addition, since it must accept intense exercise in addition to weight, it also causes problems in maintenance due to damage of mats and springs.

In recent years, there has been a case in which an air-injected play apparatus is installed.

Such an air injecting type play device fixes an air expansion membrane for air injection on the ground, injects air, adjusts pressure when necessary, and performs elasticity and buffering functions. The structure has better structural stability than the trampoline mentioned above, Ensure safe play.

Registration Practical Utility Model No. 20-1999-0021740 discloses such an air injection type amusement structure, and Fig. 1 is a side sectional view thereof.

Specifically, a sand layer 40 is formed around the bottom plate 10, and the sand layer 40 encapsulates the edges of the bottom plate 10 and the top film 20 . The top film 20 is tightly connected and fixed to the edge of the bottom plate 10 and is sealed and cooperated with the bottom plate 10 by using airtightness and elastic tents so that air Thereby forming a peak 21 which is inflated upward.

However, such an air-injecting type play device has a problem in that the movement of air is continuously generated due to the load of the human body being applied to the upper surface, causing a variation in bearing force and making stable play difficult.

In addition, since the air that is charged into the interior continuously escapes, if the proper amount of air is not injected in a timely manner, the shape can not be maintained, which may cause a safety accident in a serious case.

Also, the process of discharging and re-injecting air during the maintenance process is cumbersome and requires too much manpower and time.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a domed play device including an air injection device which is excellent in structural stability and can be safely played.

It is another object of the present invention to provide a domed play apparatus including an air injecting apparatus which is easy to inject and discharge air and is reliable in operation.

The present invention relates to an air conditioner comprising: an outer casing part having a rim on a ground and forming an air filling space therein; An air column which is partitioned from an air filling space inside the outer casing; An input / output line for supplying air to and discharging air from the air column; And an injection unit connected to the end of the input / output line and discharging air from the upper side of the air column internal space. The air injected from the injection unit forms the air column shape first, thereby elevating the overall structure, The present invention provides a domed play apparatus including an air injection device that flows into a filling space and is shaped like a dome. Accordingly, since the shape of the air column is determined first, the load at the time of input to the air filling space can be reduced, and the time for construction is shortened.

It is preferable that the injection port of the injection section is disposed adjacent to the bottom of the outer membrane part from the inside of the air column, and the air is filled while the air is conveyed downward.

In addition, the air column has a communication hole communicating with the air filling space at the bottom, and the communication hole provides a resistance to the flow generated by a load or an impact eccentrically applied to the outer film portion, Can be prevented from being changed.

The input / output line includes an input part connected to the blowing part to supply air, an exhaust part that is an inner pipe communicating with the outside air before the connection part between the blowing part and a valve that opens / closes the communication with the outside air of the exhaust part, May be provided.

A plurality of air balls disposed on an upper surface of the outer casing and capable of independently generating an elastic force; And a cover member disposed to cover the upper surface to maintain the position of the plurality of air balls.

According to the present invention, since the air column supports the overall shape, even if an excessive load or an impact is generated in a concentrated area, the shape is not collapsed and stable play is possible.

In addition, since air is primarily injected into the air column at the time of injecting air and injected into the air filling space formed by the outer film portion, air in the inner portion of the outer film portion can be injected after the overall shape is taken, Can be remarkably reduced. In this case, the construction time is shortened and the economical efficiency is improved in forming the dome shape. Also, since the exhaust and input can be controlled by a single input / output line, the structure is simple and stable, and the reliability of use is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a domed play apparatus including an air injection apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the following description, when a part is referred to as being 'connected' to another part, it includes not only a direct connection but also a case where another part or device is connected in between. In addition, when a part is referred to as including an element, it is to be understood that the element may include other elements, not the exclusion of any other element, unless specifically stated otherwise.

The present invention basically comprises an outer film portion having a rim on the ground and forming an air filling space therein, an air column which is partitioned from an air filling space inside the outer film portion, And an injection unit connected to the end of the input / output line and discharging air from the upper side of the air column internal space.

The dome-type play apparatus including the air injection apparatus of the present invention is basically installed in a predetermined ground, and can be filled with air if necessary, and the injection pressure can be adjusted as needed. So that the elasticity of the jumping can be appropriately controlled as well as the safe jumping play, thereby providing a domed play device that can simultaneously guarantee the effect of play, safe use, and maintainability.

Here, the ground is basically the foundation of the foundation which can provide the basic ceiling work and the degree of sealing of the air to some extent, regardless of the soil itself or the foundation on which the concrete is laid. Also, it should be understood that the predetermined surface of the building where the domed play apparatus including the air injection apparatus of the present invention can be installed is also included in the concept of the ground.

2 is a side cross-sectional view illustrating a domed play apparatus including an air injection apparatus according to the present invention.

As described above, the outer film part 1100 is fixed to the ground 10 so that a predetermined sealing material can be disposed or work can be performed so that air does not flow in and out from the rim and the bottom surface. In this regard, the construction of the ground will be described later.

It is preferable that the outer membrane part 1100 is formed of a material that can have a certain degree of expandability according to the infusion of air and can assure its durability as it receives a constant load from the upper surface. In consideration of durability and composition, It is preferable to form the polyurethane coating layer in consideration of the air shielding.

The air column 1200 forms a column space partitioned in an air filling space inside the outer casing part 1100. Air supplied from the outside through the input / output line 2200 is firstly inputted through the air column 1200 .

These air pillars 1200 may be arranged in two opposing directions with a center in both directions as shown, but it is also contemplated that only one of the air pillars 1200 is disposed on the center side or arranged in a lattice form, and such arrangement or shape is optional.

The air column 1200 communicates with an air filling space, which is a remaining space formed by a portion of the bottom portion 1100 of the air column 1200. Air injected from the injection portion 2400 passes through a predetermined Is discharged downward through a communication port (reference numeral is not shown), and is supplied to the air filling space secondarily.

Since the air column 1200 provides a somewhat independent space in the internal space formed by the outer membrane part 1100, even if a section where the air inside is over-tight due to a shock in a part of the air filling space is generated, So that the overall shape is not collapsed. When the entire structure is formed as one space as in the prior art of FIG. 1, when a strong impact is generated in a part of the air, the air flows to the other side and the shape is deformed. When the inclination changes, It is possible to cause a fear that the center of gravity can not fall and fall. In the present invention, since the entire structure can be maintained by the air pillars 1200 even when a strong impact is generated, it is noted that the above problem is solved so that safe play can be performed.

The spacing of the communication holes may function as a flow path for performing a predetermined damping function and may function to buffer the abrupt flow from the air filling space and to transfer the air to the air column 1200. At this time, the damping force can be adjusted by the cross-sectional area of the communication hole, which is optional.

The input / output line 2200 functions to supply or discharge air having a predetermined pressure directly to each air column 1200. The input / output line 2200 may be formed separately from the input line and the output line. However, in this case, the input / output line 2200 is structurally complicated and there is a fear that the air may become excessively long considering the construction of the input / output line 2200. It is preferable that the input / output line 2200 is formed as one line as shown in FIG. In addition, when the input / output line 2200 is formed in a single tube shape, the input and output of the air can be performed in the same region, so that it is possible to control the pressure more effectively.

The input / output line 2200 is connected to an air control unit 2100 at one end. The air control unit 2100 includes a predetermined blower to supply air having pressure to the input / output line 2200. The air control unit 2100 may have a predetermined discharge structure for discharging air from the input / output line 2200 to the outside air, which will be described later.

The other end of the input / output line 2200 may have a plurality of ends and is connected to the bottom of the air column 1200. More specifically, the input / output line 2200 is disposed substantially horizontally in the ground 10 so as to cross the bottom portion of the outer membrane portion 1100, and the distal portion 2300 is disposed substantially at the center of the bottom of the air column 1200 And bent upward to have an outlet.

The distal end portion 2300 may discharge air to the bottom portion of the direct air column 1200. However, as described above, the communication port is disposed at the bottom of the air column 1200 and the air from the input / output line 2200 flows through the air column It is preferable that the injection port is formed on the upper side, that is, the portion adjacent to the bottom portion of the outer membrane portion 1100. In this case, Accordingly, the distal end portion 2300 is connected to the injection portion 2400, and the injection port of the injection portion 2400 may be disposed adjacent to the upper end of the air column 1200.

In one embodiment, the injection part 2400 may be formed of a material such as synthetic rubber capable of maintaining a certain shape. At this time, since the injection part 2400 can maintain the shape of the air column 1200 to some extent, the air inside the air filling part is excessively small or abnormal, and the pressure inside the air column 1200 is higher than the air filling part It has the advantage of being able to capture the overall shape even when it is low.

However, in this case, it may be inconvenient when the air is discharged and stored or maintained. Therefore, in another embodiment, the injection unit 2400 maintains the shape when the air is supplied, A case of being formed of a soft material so as to be disposed in a folded state at the bottom of the air column 1200 may be considered. In the concept of the present invention, since the injection unit 2400 discharges the compressed air to the upper space of the air column 1200 and flows downward, the shape can be maintained only when necessary.

When the compressed air of the air control unit 2100 is primarily injected into the air column 1200 as described above, it is possible to improve the time required to capture the overall shape of the domed play apparatus as compared with the conventional art. Conventionally, since the air is uniformly supplied to the entire space by the single discharge unit, it is required to wait for a gradual rise time according to the filling of the air. However, it takes about 10 to 30 minutes have. However, according to the concept of the air column of the present invention, when the air is first injected into the air column 1200, the air column 1200 is lifted up to take up the overall structure, so that the air filling space is formed first, Not only the air can be injected without resistance but also the air filling space can be formed by the air column first to form the negative pressure and the load of the air control unit 2100 can be reduced so that the filling time can be saved remarkably .
