Rubber Air Cushion Sofa
A sofa includes a mounting frame, a plurality of air cushions mounted on the mounting frame, a controller connected with the air cushions, and an air compressor connected with the controller to supply air into the air cushions. The mounting frame is made of aluminum alloy. Each of the air cushions is made of rubber material. The controller regulates the air pressure in each of the air cushions so as to adjust hardness and tension of each of the air cushions. Thus, the air cushions have different curvatures and profiles so that when the air cushions can be used to support a user's head, neck, back, hands, waist, hip and legs so as to provide a comfortable sensation to the user.
1. Field of the Invention
The present invention relates to a sofa and, more particularly, to a rubber air cushion sofa.
2. Description of the Related Art
A conventional sofa 1 in accordance with the prior art shown in
In accordance with the present invention, there is provided a sofa, comprising a mounting frame, a plurality of air cushions mounted on the mounting frame, a controller connected with the air cushions, and an air compressor connected with the controller to supply air into the air cushions by operation of the controller. The mounting frame is made of metallic material. Preferably, the mounting frame is made of aluminum alloy. Each of the air cushions is made of rubber material and has a hollow inside. Each of the air cushions has a side provided with an air nozzle. The controller includes a plurality of air pipes each connected with the air nozzle of a respective one of the air cushions. The controller regulates an air pressure in each of the air cushions so as to adjust hardness and tension of each of the air cushions. Each of the air cushions has two open end portions each locked onto the mounting frame by one of a plurality of clamping members.
Preferably, each of the air cushions has an outer wall whose wall thickness is adjustable to adjust a curvature of each of the air cushions.
Preferably, each of the two open end portions of each of the air cushions has a lower end piece and an upper end piece which has a length greater than that of the lower end piece.
According to the primary advantage of the present invention, the air cushions have different curvatures and profiles to satisfy the ergonomic design so that when a user is seated on the air cushions, the air cushions can be used to support the user's head, neck, back, hands, waist, hip and legs so as to provide a comfortable sensation to the user.
According to another advantage of the present invention, each of the air cushions is inflated and deflated individually so that the tension of each of the air cushions can be adjusted freely to satisfy the user's requirements.
According to a further advantage of the present invention, the mounting frame is made of metallic material, and each of the air cushions is made of rubber material so that the sofa is refractory and fireproof to block a fire accident.
According to a further advantage of the present invention, the mounting frame is made of aluminum alloy, and each of the air cushions is made of rubber material so that the sofa has a lighter weight and can function as a float that floats on the water level when a water accident or flood happens.
According to a further advantage of the present invention, the mounting frame and each of the air cushions are waterproof so that the sofa has a waterproof function and can be washed directly by water to facilitate the user cleaning the sofa.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The sofa 4 further comprises a covering (not shown) encompassing the air cushions 2. Preferably, the covering is made of leather or the like.
The mounting frame 3 is made of metallic material. Preferably, the mounting frame 3 is made of aluminum alloy so that the mounting frame 3 has a lighter weight. The mounting frame 3 has a bottom provided with an antiskid pad (not shown) to increase stability of the mounting frame 3.
Each of the air cushions 2 is made of rubber material and has a hollow inside so that each of the air cushions 2 is elastic and flexible. Each of the air cushions 2 has a side provided with an air nozzle 22. The controller 6 includes a plurality of air pipes 60 each connected with the air nozzle 22 of a respective one of the air cushions 2. The controller 6 can regulate an air pressure in each of the air cushions 2 so as to adjust hardness and tension of each of the air cushions 2. The controller 6 further includes a plurality of air taps 61 each connected with a respective one of the air pipes 60. Thus, each of the air taps 61 of the controller 6 is connected to the air nozzle 22 of a respective one of the air cushions 2 through a respective one of the air pipes 60.
The air compressor 5 is mounted on the bottom of the mounting frame 3 and includes a retractable hose 50 which is connected to one of the air taps 61 of the controller 6. The air compressor 5 further includes a plug 52 which is inserted into a socket (not shown) to supply an electric power into the air compressor 5. The retractable hose 50 of the air compressor 5 has a free end provided with a control head 51 which has an inflation terminal 511 and a deflation terminal 512 to fill air into or release air from one of the air taps 61 of the controller 6 so as to inflate or deflate one of the air cushions 2.

Accordingly, the air cushions 2 have different curvatures and profiles to satisfy the ergonomic design so that when a user is seated on the air cushions 2, the air cushions 2 can be used to support the user's head, neck, back, hands, waist, hip and legs so as to provide a comfortable sensation to the user. In addition, each of the air cushions 2 is inflated and deflated individually so that the tension of each of the air cushions 2 can be adjusted freely to satisfy the user's requirements. Further, the mounting frame 3 is made of metallic material, and each of the air cushions 2 is made of rubber material so that the sofa 4 is refractory and fireproof to block a fire accident. Further, the mounting frame 3 is made of aluminum alloy, and each of the air cushions 2 is made of rubber material so that the sofa 4 has a lighter weight and can function as a float that floats on the water level when a water accident or flood happens. Further, the mounting frame 3 and each of the air cushions 2 are waterproof so that the sofa 4 has a waterproof function and can be washed directly by water to facilitate the user cleaning the sofa 4.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
