Abstract:
An adhesive tape pedestal is equipped with a cyclometer associated with a visual window to indicated the length of tape that helps the user pull out just desired length of tape so as to preclude wasting of tape. Besides, the cyclometer can indicate the total length of tape contained in a roll when it is used up that helps the user check whether or not the actual length of tape is in comply with the nominal length.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the invention  
         [0002]     The present invention relates to an improved structure for an adhesive tape pedestal , and in particular, to a tape pedestal which is associated with a cyclometer to indicate the used portion of the adhesive tape in a roll.  
         [0003]     2. Description of the prior art  
         [0004]     The adhesive tape is too-commonly used everywhere such as workshops, department stores, and private homes for packaging or fixing objects by adhering. It is consumed astonishingly a large amount in department stores during the season of bargain sales. Most of people have experienced that it is tedious to make packages or adhere something with the adhesive tape. First of all, the tip of a roll of tape must be found out, pull out the necessary length of tape, then restore the remained tape back properly. Next time the tape is to be used, the user has to looking for the tip of the tape again.  
         [0005]     A somewhat convenient adhesive tape rolls with a tape pedestal have been on the market for a long time, either a handhold type or an on-table type. For example, a conventional handhold type is shown in  FIG. 1 . It includes a pedestal  8  with a serrated cutting blade  81  equipped in front of the tip of a tape roll. Behind both sides of the blade  81  are two supporting walls  82  each erected one side thereof. One of the supporting wall  82  is conjoined to a bobbin  83  around which the tape  5  is coiled. A roller  84  is sandwiched between the two supporting walls  82  and a transmission wheel  85  is provided on each side on the top ends of the walls  82  over the roller  84 . A hood  86  for the tape roll is hinged to the rear of the walls  82 . When using the tape  5  which is rolled around the bobbin  83 , the tip of the tape  5  is pulled out and passed through the clearance between the roller  84  and the transmission wheel  85  to adhere the tape  5  onto the object  6  with a required length, the remaining portion is cut away with a serrated cutting blade  81 . By doing so the user may feel better in handling the tape associated with a cutting blade  81  than that without it. However, there is a problem should the supplier of the tap is dishonest enough to sell the tape roll whose length is made purposely shorter than its nominal length, the user can not discover such a shameful behavior could be played in the seller&#39;s side because the user is unable to measure how long the actual length of the tape he/she has bought is.  
       SUMMARY OF THE INVENTION  
       [0006]     The present invention is made for palliating the noticeable defects inherent to the prior arts described above, and for protecting the consumer&#39;s right to check up the actual length of the tape contained in a roll after the tape is used up so as to help select a good product of another brand manufactured by a honest maker.  
         [0007]     After a long time efforts of study and experience, the inventor has succeeded in coming up with a novel structure for adhesive tape pedestal as the present invention provides.  
         [0008]     Accordingly, the present invention is to provide an adhesive tape structure which is associated with a cyclometer that helps the user check the actual length in a roll of tape he/she has purchased.  
         [0009]     Another, the present invention is to provided a tape pedestal which is equipped with a visual window so as to enable the user to observe from the cyclometer indication the length of tape section being pulled out for use thereby assisting the user to pull out a just sufficient length of tape from the roll.  
         [0010]     Still another, this improved structure for tape pedestal can be constructed simply for handling and manufacturing with a low cost.  
         [0011]     Accordingly, the tape pedestal of the present invention consists of a pedestal body, two supporting walls, a serrated cutting blade, a hood, a roller, a driving wheel and a cyclometer. A visual window is provided on the pedestal body appropriately for observing the indication on the cyclometer which is driven by a gear mechanism. The cutting blade is set in the front end of the pedestal body and sustained by the two supporting walls at its two sides. The hood is hinged to the rear ends of the supporting walls, and the roller is rotatably sandwiched between the supporting walls behind the cutter blade. Two axles are provided behind the roller each attached respectively to the supporting wall at its own side, and a driving wheel is attached to each axle. One of the driving wheel serves as a means for driving the cyclometer by gear transmission. Besides, one of the supporting wall is conjoined to a bobbin which carries a roll of tape. With this structure the length of tape pulled out of the roll can be observed by the user through the visual window therefore the user is able to estimate proper length of the tape to be pulled out by observing the indication on the cyclometer so as not to waste the tape, meanwhile, the total length of specified roll of tape can appear on the cyclometer after the tape is used up that helps the user check whether or not the actual length of the tape in a roll complies with the nominal value thereof. This will benefit a great deal to those who consume a large amount of tape regularly.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0021]     The structure for the adhesive tape pedestal according to the present invention will now be illustrated in conjunction with  FIG. 2  through  FIG. 4 .  
         [0022]     A pedestal body  1  has a visual window  11  opened on this bottom at a proper location, and a serrated cutting blade  12  is provided at its front edge thereof. The cutting blade  12  is sustained by two supporting walls  13  and  14  erected at its two sides on the pedestal body  1 . The supporting wall  13  is conjoined to a bobbin  15  which carries a roll of tape  5 . The hood  16  is hinged turnably to the rear ends of the supporting walls  13 ,  14 . A roller  17  is rotatably sandwiched between the two supporting walls  13  and  14  behind the cutter blade  12 . A first and a second axle  18  and  19  are provide behind the roller  17  attached respectively to the supporting walls  13  and  14 . The first and second axles  18  and  19  are preferably disposed at the same height with the roller  17 , but it is allowable to dispose them lower than the roller  17 .  
         [0023]     A cyclometer  2  is associated with a driving member  21  at one side and an indicator  22  beneath it. The driving member  21  is for driving the cyclometer  2  to rotate and count the length of the extended tape. The cyclometer  2  is equipped under a visual window  11  on the pedestal body  1 . The driving member  21  may be formed of a sensor actuated switch or a trigger switch.  
         [0024]     A first driving wheel  3  has a central fitting hole  31  to couple with the first axle  18  thereby enabling it to rotate about the first axle  18 .  
         [0025]     A second driving wheel  4  also has a central fitting hole  41  to couple with the second axle  19  thereby enabling it to rotate about the second axle  19 . The second driving wheel  4  is associated with a transmission member  42  at its side. The transmission member  42  may be a gear wheel or a rocking arm or the like.  
         [0026]     The improved structure for adhesive tape pedestal ( 1 ) is constructed of the component parts described above.  
         [0027]     Please refer to  FIGS. 5A and 5B  for understanding the operation of the present invention. At first a roll of tape  5  is coiled around the bobbin  15  set on the pedestal body  1  with its tip  51  pulled down passing between the driving wheels  3 ,  4  and stretches out of the bottom of the roller  17  so as to adhere the pulled section of the tape  5  to an object  6  by slightly pulling back the tape  5  to roll back the two driving wheels  3 ,  4  with the roller  17   a  little bit thereby applying an appropriate tensile force to the tape  5  that can assist the tape  5  to adhere on the object  6  tightly. At this moment, the second driving wheel  4  drives the driving member  21  of the cyclometer  2  via its transmission member  42  so as to actuate the cyclometer  2 .  
         [0028]     Please refer to  FIG. 6  for understanding the function of the cyclometer  2 . The driving member  21 , which being a sensor actuated switch or a trigger switch, can detect the amount of motion of the transmission member  42  (for example, a rocking arm or the like) of the second driving wheel  4  and actuate the cyclometer  2  to indicate its value. For instance, one revolution of the rocking arm  42  represents 5 cm etc. By so, not only the total length of the tape  5  contained in a particular roll can be known after using up the rolled tape thereby assisting to check the actual length against the nominal length labeled on the product and protect the right of the consumer against the dishonest maker.  
         [0029]      FIG. 7  shows another embodiment of the present invention in which the adhesive tape pedestal is made into a table type pedestal  7 . The construction is similar to that described above. A roller  71  is associated with a driving wheel  72  and an auxiliary member  73  which acts simultaneously with a transmission member  721  of the driven wheel  72 . The auxiliary member  73  acts to drive the driving member  741  equipped with a cyclometer  74  starts action of the cyclometer  74  to measure the length of the tape  5  which is observable from a visual window  72 .  
         [0030]     It emerges from the above description that the present invention has several noteworthy advantages compared to any product that is made according to prior arts, namely:  
         [0031]     1. Provision of a cyclometer helps the user check the actual length in a roll of tape he/she has purchased with the nominal value leveled on the product so as to protect the right of the consumer against the dishonest maker.  
         [0032]     2. Provision of a cyclometer with a visual window makes it possible for the user to observe the cyclometer indication from the visual window the length of tape section being pulled out for use thereby preventing the user from pulling out improper length of the tape.  
         [0033]     3. This improved structure for tape pedestal is of a simple structure easy for handling and manufacturing with a low cost.  
         [0034]     Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
