Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a brassiere and more particularly, to an adjustable brassiere support.  
         [0003]     2. Description of the Related Art  
         [0004]      FIG. 1  is an exploded view of a conventional brassiere. According to this design, two pockets  2 ′ are respectively provided inside the cups of the brassiere  1 ′, and two paddings  3 ′ are respectively inserted into the pockets  2 ′ to support the cups of the brassiere  1 ′ in shape. According to this design, the paddings  3 ′ are not adjustable to fit the user&#39;s breasts respectively. In order to eliminate this problem, adjustable paddings are developed.  FIG. 2  shows two adjustable paddings  4 ′ for brassiere. Each padding  4 ′ has a valve  5 ′ through which the desired amount of air/fluid can be filled into the padding  4 ′. However, this design of adjustable padding  4 ′ is still not satisfactory in function. When the padding  4 ′ received a high compressive force, the valve  5 ′ may break, thereby causing a leakage. Further, the valve  5 ′ starts to wear after a long use.  
       SUMMARY OF THE INVENTION  
       [0005]     The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an adjustable brassiere support, which can be conveniently adjusted to fit the user&#39;s two breasts. It is another object of the present invention to provide an adjustable brassiere support, which is durable in use.  
         [0006]     To achieve these and other objects of the present invention, the adjustable breasts support comprises two bladders filled with air/fluid, a neck in fluid communication between the bladders, and a clip for fastening to the neck to stop the passage between the bladders.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]     Referring to  FIG. 3 , an adjustable brassiere support in accordance with the present invention is formed of two waterproof plastic sheet members  10  peripherally sealed with a sealing line  12  by ultrasonic heat sealing. The two waterproof plastic sheet members  10  are symmetrical, each having a narrow middle part  11 . When the two waterproof plastic sheet members  10  are peripherally sealed together, they form two bladders  100  and a tubular neck  110  connected between the bladders  100 . The tubular neck  110  is formed of the narrow middle part  11  of each of the two waterproof plastic sheet members  10 . When sealing, the two waterproof plastic sheet members  10  peripherally together with a heat sealing apparatus to form the sealing line  12 , a small hole (not shown) is left so that a sufficient amount of air (or fluid) can be filled into the bladders  100  and the tubular neck  110 . After filling of air (or fluid), this small hole is sealed to keep the bladders  100  and the tubular neck  110  in an airtight status.  
         [0017]     Referring to  FIGS. 5 and 7 , the two bladders  100  of the adjustable brassiere support are inserted into in the pockets  2  inside the two cups of a brassiere  1 . When in use, the user can squeeze one of the two bladders  100  of the adjustable brassiere to force the contained air (or fluid) toward the other of the two bladders  100  via the tubular neck  110  so as to adjust the inflation status of each bladder  100  subject to the size of the corresponding breast. When adjusted, a clip  15  is fastened to the tubular neck  110  to block the passage between the bladders  100 .  
         [0018]     Referring to  FIGS. 6A and 6B , the bladders of the adjustable brassiere may be partially sealed to form oblique seam lines  13  or arched seam lines  14 . These seam lines  13 , 14  cause the center area of each bladder of the brassiere to curve outwards, improving the breast lifting effect.  
         [0019]     Referring to  FIG. 8 , a valve  20  may be installed in the tubular neck  110  between the bladders  100  (not shown). The valve  20  comprises a valve hole  21  in fluid communication between the two bladders  100 , and a control plug  22  rotatable between a first position to block the valve hole  21  and a second position to open the valve hole  21 .  
         [0020]     A prototype of adjustable brassiere support has been constructed with the features of FIGS.  3 ˜ 8 . The adjustable brassiere support functions smoothly to provide all the features discussed earlier.  
         [0021]     Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
