Title: Inflatable sofa set

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a sofa, and more particularly to a collapsible and inflatable three-in-one sofa set which comprises a receiving body for receiving the sofa after the sofa is deflated. 
     2. Description of the Prior Art 
     Home is a place for people to rest and relax after a whole day work, and various kinds of furniture play an important role at home. For example, comfortable furniture can make you more comfortable, or even can help you remove the whole day&#39;s tiredness, for instance, sitting or lying on a sofa can help relieve fatigue. However, such a sofa occupies a large space and cannot be easily moved and is not easy for storage due to its large size and weight. Therefore, inflatable sofas appeared in the market but they are all not ideal because some air inflation apparatuses must be outwardly connected but are not of built-in type, or even worse, some inflatable sofas are not collapsible. Therefore, although such an inflatable sofa can be deflated after use, it will become irregular in shape after being folded, so it is untidy. Moreover, if put the deflated sofa in the cabinet or store room, it will probably be difficult to find it out when want to use it. 
     It is therefore tried by the inventor to develop a simply structured inflatable sofa set which can be quickly inflated or deflated and comprises a receiving body which not only can be used to receive the deflated sofa but also can be used as a table, a tea table, a chair, or a game chessboard. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide an inflatable sofa set which is simply structured and convenient for storage since it comprises a receiving body for receiving sofas, and is provided with a plurality of wheels at a lower portion of the receiving body for conveniently transporting the sofa set for use indoors and/or outdoors. 
     To achieve the objective of the present invention, the inflatable sofa set comprises a receiving body, a pump and at least one airbag. The receiving body is provided with a receiving space for receiving the airbag and the pump. The pump is connected to the airbag for inflating it into a sofa. When not in use, the sofa can be deflated by the pump and then received in the receiving space of the receiving body, so it looks tidy and neat and occupies less space. In addition, the receiving body can also be used as a table, so that the sofa set of the present invention is convenient for storage and versatile. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1-4 , an inflatable sofa set in accordance with the present invention comprises a receiving body  10 , a pump  20  and two airbags  30 . 
     The receiving body  10  is provided with a receiving space  11  and a cover  12 . The receiving space  11  is defined with an opening  111 , and the cover  12  covers the opening  111 . Both lateral edges of the opening  111  of the receiving body  10  are defined with a concave portion  13 , respectively. 
     The pump  20  is received in the receiving space  11  of the receiving body  10  and is provided with a power supply device  21 . The pump  20  is connected to two control knobs  22  and an indicating lamp  23  which are located on an outer surface of the receiving body  10 . The control knobs  22  can control the pump  20  to perform inflation or deflation operations, separately or synchronously. The indicating lamp  23  can emit warning light and cut off the power supply when the pump  20  is overloaded, so as to stop the inflation or deflation operation. Each airbag  30  is connected to the pump  20  by a connecting portion  31  and is received in the receiving space  11  of the receiving body  10 . The pump  20  can inflate or deflate the airbags  30 , separately or synchronously. After being inflated, each airbag  30  becomes a sofa  300 . 
     When the airbags  31  are received in the receiving body  10 , the receiving body  10  can be used as a table, a tea table, a chair, or a game chessboard. 
     To use the sofa, the user can open the cover  12  to take the airbags  30  out of the receiving body  10  via the opening  111 , and then turn the control knobs  22  to an inflation mode so as to make the pump  20  inflate the airbags  30  into the sofa  300 . 
     The pump  20  is connected to the indicating lamp  23 , so that when the pump  20  is overloaded due to the sofas  300  are over-inflated (or are inflated for too long), the indicating lamp  23  will emit warning light and cut off the power supply, so as to stop the inflation or deflation operation. When the airbags  30  are inflated into the sofas  300 , since the airbags  30  are connected to the pump  20  by the connecting portions  31 , the connecting portions  31  will be extended out of the concave portions  13  and the cover  12  can also cover the receiving body  10  after the airbags  30  are inflated into the sofas  300 . At this time, the receiving body  10  is located between the sofas  300  and can be used as the tea table. In addition, the power supply device  21  of the pump  20  can be an alternating current (AC) plug or a direct current (DC) battery. 
     Furthermore, the present invention includes but not limited to two airbags  30 , it may also include one, or more than two airbags  30 . 
     Moreover, an outer surface of the cover  12  of the receiving body  10  can be provided with different kinds of chessboards, such as, Chinese chess, Caissa Chess, five chess and so on, and the cover  12  can be used as a chessboard after the receiving body  10  is closed. Thereby, the additional function of the receiving body  10  is improved, and the economic benefits and recreational benefits of the inflatable sofa set are relatively increased. 
     Referring to  FIG. 4  again, at a lower portion of the receiving body  10  is provided a plurality of wheels  40  for conveniently transporting the sofa set for use indoors and/or outdoors. 
     Referring to  FIG. 5 , the outer surface of the receiving body  10  is provided with an audio device  50  having an audio input portion  51  for connecting to a MP3 or a notebook and an audio output portion  52  for playing sound effects, so as to further increase the additional function and value of the sofa set. 
     While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
