Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an examining device, and more particularly to a water resistant and ventilatory examining device for cloth to see if the cloth produced is able to resist water penetration and is air-permeable.  
         [0003]     2. Description of Related Art  
         [0004]     Nowadays, cloth made for clothes has meshes smaller than a water molecule and larger than an air molecule so that the cloth is able to resist water penetration and still allow air to penetrate. Thus, when a user is wearing clothes made of the specially produced cloth, the rain drops will not penetrate the cloth and the user is able to keep dry during a rainy day. In the meantime, the moisture perspired by the user is able to penetrate the cloth and the user is able to feel comfortable even after a large amount of perspiration.  
         [0005]     In order to test whether the cloth so produced has the desired function, different and expensive machinery is introduced to the market. Although they do meet the requirements and successfully test the cloth, complex steps and large manual effort are involved, which hinders the popularity of the existing testing devices.  
         [0006]     To overcome the shortcomings, the present invention tends to provide an improved examining device to mitigate the aforementioned problems.  
       SUMMARY OF THE INVENTION  
       [0007]     The primary objective of the present invention is to provide an improved water resistant and ventilatory examining device for cloth. The examining device is simple in structure and low in cost.  
         [0008]     Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]     With reference to  FIG. 1 , the water resistant and ventilatory examining device for cloth includes a first container ( 10 ), a second container ( 12 ), a connector ( 15 ) sandwiched between the first container ( 10 ) and the second container ( 12 ) and an air supply device ( 14 ).  
         [0017]     The first container ( 10 ) has a bottom open end defined in a bottom end of the first container ( 10 ) and a top open end defined in a top end of the first container ( 10 ). A first annular groove ( 11 ) is defined in an outer periphery adjacent to the open end.  
         [0018]     The second container ( 12 ) has an open end defined in a top end of the second container ( 12 ) and a closed end defined in a bottom end of the second container ( 12 ). A second annular groove ( 13 ) is defined in an outer periphery adjacent to the open end of the second container ( 12 ). An air hole ( 120 ) is defined through a side wall of the second container ( 12 ) to allow the surrounding air to communicate with the inside of the second container ( 12 ).  
         [0019]     The air supply device ( 14 ) has an air bulb ( 141 ) and a tube ( 142 ) extending from the air bulb ( 141 ) and having a nozzle ( 143 ) formed on a free end of the tube ( 142 ) to correspond to the air hole ( 120 ) of the second container ( 12 ).  
         [0020]     With reference to  FIG. 2  and using  FIG. 1  for reference, it is noted that the connector ( 15 ) is a ring-like member and has an upper ring ( 15   a ) with a first annular projection ( 151 ) formed on an inner face of the upper ring ( 15   a ) to correspond to the first groove ( 11 ) of the first container ( 10 ) and a lower ring ( 15   b ) with a second annular projection ( 152 ) formed on an inner face of the lower ring ( 15   b ) to correspond to the second groove ( 13 ) of the second container ( 12 ).  
         [0021]     With reference to  FIG. 3 , when the examining device is assembled, it is to be noted that the nozzle ( 143 ) is securely connected to the air hole ( 120 ) of the second container ( 12 ). The second annular projection ( 152 ) is received in the second groove ( 13 ) of the second container ( 12 ) and the first annular projection ( 151 ) is received in the first groove ( 11 ) of the first container ( 10 ).  
         [0022]     With reference to  FIG. 4 , when the examining device of the present invention is in application with a cloth ( 16 ), the cloth ( 16 ) is placed on top of the connector ( 15 ). Then, after the first container ( 10 ) is placed on top of the connector ( 15 ) and the first annular projection (I  51 ) is received in the first groove ( 11 ) of the first container ( 10 ), the cloth ( 16 ) is securely clamped by an inner face defining the first groove ( 11 ) and the first annular projection ( 151 ) of the connector ( 1   5 ). When the aforementioned assembly is completed, the first container ( 10 ) is filled with water from the top open end of the first container ( 10 ) and air is pumped into the second container ( 12 ) by an operator squeezing the air bulb ( 241 ). Therefore, the user is able to observe whether the cloth ( 16 ) is water resistant and ventilatory by observing whether water passes down into the second container ( 12 ) and air passes up into the first container ( 10 ).  
         [0023]     With reference to  FIG. 5 , a different embodiment of the present invention is shown and has a first container ( 20 ), a second container ( 22 ), an air supply device ( 24 ) and a securing device ( 25 ).  
         [0024]     The first container ( 20 ) has two open ends with a top ring ( 21 ) formed on a peripheral top edge of the first container ( 20 ) and having multiple through holes ( 210 ) defined through the top ring ( 21 ). The second container ( 22 ) has an open end formed on a top of the second container ( 22 ) and a closed end formed on a bottom of the second container ( 22 ) and having a bottom ring ( 23 ) formed on a peripheral bottom edge of the second container ( 22 ) and having multiple threaded holes ( 230 ) defined through the bottom ring ( 23 ) to correspond to and align with the through holes ( 210 ) of the top ring ( 21 ). An air hole ( 220 ) is defined through a side wall of the second container ( 22 ) to allow the surrounding air to communicate with the inside of the second container ( 22 ).  
         [0025]     The air supply device ( 24 ) includes an air bulb ( 241 ), a tube ( 242 ) extending out from the air bulb ( 241 ) and a nozzle ( 243 ) formed on a free end of the tube ( 242 ) to correspond to the air hole ( 220 ) of the second container ( 22 ).  
         [0026]     The securing device ( 25 ) has multiple threaded bolts ( 251 ) and nuts ( 252 ) to correspond to the through holes ( 210 ) of the first container and the threaded holes ( 230 ) of the second container ( 22 ).  
         [0027]     With reference to  FIG. 6 , it is noted that after the examining device of the present invention is assembled, the threaded bolts ( 251 ) are extended through the through holes ( 210 ) and into the threaded holes ( 230 ) to combine the first and the second containers ( 21 , 22 ). The nuts ( 252 ) are applied to screw onto the threaded bolts ( 251 ) so as to securely engage the first container ( 21 ) with the second container ( 22 ). The nozzle ( 243 ) is connected to the air hole ( 220 ) of the second container ( 22 ).  
         [0028]     With reference to  FIG. 7 , before the application of the examining device, a cloth ( 26 ) is first sandwiched between the bottom of the first container ( 20 ) and the top of the second container ( 22 ). After the extension of the threaded bolts ( 251 ) into the through holes ( 210 ) and the threaded holes ( 230 ) and the nuts ( 252 ) are screwed onto the threaded bolts ( 251 ), the secure engagement between the first container ( 20 ) and the second container ( 22 ) securely clamps the cloth ( 26 ). Thus by pouring water into the first container ( 20 ) from the top open end of the first container ( 20 ), an operator is able to observe whether the cloth ( 26 ) is water resistant by whether water passes through the cloth. In the meantime, pumping air into the second container ( 22 ) by the operator squeezing the air bulb ( 241 ) to cause air to pass into the second container ( 22 ) via the nozzle ( 243 ) reveals whether bubbles pass through the cloth ( 26 ) and into the water in the first container ( 20 ). If bubbles do pass through the cloth ( 26 ), the cloth ( 26 ) is ventilatory.  
         [0029]     It is to be noted that the entire structure of the examining device is simple and thus the cost is low. Further the testing procedure is quite easy for the operator so that the test can be performed any time at any place.  
         [0030]     It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
