Title: Garbage can capable of compresing garbage volume

Description:
BACKGROUND OF THE INVENTION 
   1. Field of The Invention 
   The present invention relates to a garbage can capable of compressing garbage volume and, particularly, to a garbage can, which is capable of compressing the size of the garbage. 
   2. Description of Related Art 
   The garbage contained in the conventional garbage can is usually full of loose and bulgy wastes so that it is required to fill in a lot of garbage bags. Especially, in case of the handling fees for the garbage being counted with the number of the garbage bags, the expenses resulting from the garbage bags become much high. 
   SUMMARY OF THE INVENTION 
   An object of the present invention is to provide a garbage can capable of compressing garbage volume, with which the garbage therein can be squeezed easily so that the compressed garbage occupies less space and the consumption of garbage bags can be lower down considerably.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The present invention is a garbage can that is able to compress garbage volume. 
   The garbage in the garbage can in general is usually very loose, which is a waste of the garbage bag, a concern especially in the area charging “receiving fees as per bag”. 
   The idea of this invention is to solve the upper loss i.e. the garbage can enables users to easily compress the garbage inside the garbage bag so as to reduce garbage volume. 
   The preferred execution examples are listed below, with diagrams, to explain the structural features of this invention. 
   Referring to  FIGS. 1  to  18 , a garbage can capable of compressing garbage volume according to the present invention includes an outer cylinder ( 10 , an inner cylinder ( 20 ), a top cylinder ( 30 ), a top cover ( 40 ), a pedal ( 50 ), reset component ( 60 ) and a pedal lever ( 70 ). 
   The outer cylinder ( 10 ) has an open top and the cross section transverse the body thereof is an oval shape with a first connection ( 11 ) at the rear end of the top. 
   The inner cylinder ( 20 ) has an open top and a receiving space. The outer diameter of the inner cylinder ( 20 ) is a little smaller than the internal diameter of the outer cylinder ( 10 ) so that the inner cylinder ( 20 ) can be inserted into the outer cylinder ( 10 ). 
   a top cylinder ( 30 ) with an upper bottom ending in a transparent arrangement, and with an outside diameter smaller than the internal diameter of the inner cylinder ( 20 ), so that the top cylinder ( 30 ) can be inserted into the inner cylinder ( 20 ). In addition, a long strip hole ( 31 ) with several intervals in the preset distance has been bored from the bottom edge of the top cylinder ( 30 ). 
   The top cover ( 40 ) has a top plate ( 41 ) with a through hole ( 42 ). The circumference of the through hole ( 42 ) extends downwards to form an inner wall ( 43 ), and the outer circumference of the top plate ( 41 ) extends downwards to form an outer wall ( 44 ) and a holding space ( 45 ) between the outer wall ( 44 ) and the inner wall ( 43 ). The front and rear ends of the space ( 45 ) respectively form the front trough ( 46 ) and back troughs ( 47 ). The first block board ( 461 ) has been placed in the middle section of the front trough ( 46 ), and the second block board ( 471 ) has been placed in the middle section of the back trough ( 47 ). Small sheaf ( 481 ) ( 482 ) ( 483 ) ( 484 ) has been respectively set in the front and back sections of the left and right side-wall of the space ( 45 ) inside the inner wall ( 43 ). The second pin connection ( 49 ) has been placed on the rear end of the top cover ( 40 ) so that the second pin connection ( 49 ) can be inserted into the first pin connection ( 11 ) of the outer cylinder ( 10 ). 
   The pedal ( 50 ) has a main board ( 51 ) and the circumference of the main board ( 51 ) has a small diameter ( 52 ) and a big diameter ( 53 ). A shoulder ( 54 ) is formed between the small diameter ( 52 ) and the big diameter ( 53 ) , and a groove trample trough is fenced between the small diameter ( 52 ) and the main board ( 51 ). The periphery of the small diameter ( 52 ) is a little smaller than the size of the inner wall ( 43 ) of the top cover ( 40 ). The front side of the main board ( 51 ) extends upwards to a block board ( 55 ) with proper width and height, and a metal sheet ( 56 ) is set at the bottom of the pedal ( 50 ), and the metal sheet ( 56 ) will adopt a stainless steel sheet. 
   The reset component ( 60 ), including the first elastic parts ( 61 ) made of extension spring, as shown in  FIG. 12 , has been inserted into the front trough ( 46 ) of the top cover ( 40 ), and its middle section has been inserted into the first block board ( 461 ). The first shroud ( 62 ) is fixed below the front trough ( 46 ) to prevent the first elastic parts ( 61 ) from disengaging from the front trough ( 46 ). The second elastic parts ( 63 ) which also adopts an extension spring, as shown in  FIG. 12 , has been inserted into the back trough ( 47 ) of the top cover ( 40 ), and its middle section has been inserted into the second block board ( 471 ). The second shroud ( 64 ) has been inserted below the back trough ( 47 ) to prevent the second elastic parts ( 63 ) from disengaging from the back trough ( 47 ). The first wire ( 65 ), with one end is attached to the left end of the first elastic parts ( 61 ). The other end bypassing the small sheaf ( 481 ) at the back section of the left side has been inserted into the left side back section of the shoulder ( 54 ) of the pedal ( 50 ). The second wire ( 66 ), with one end attached to the right side of the first elastic parts ( 61 ), the other end bypassing the small sheaf ( 482 ) at the back section of the right side, is attached to the right-side back section of the shoulder ( 54 ) of the pedal ( 50 ). The third wire ( 67 ), with one end attached to the left end of the second elastic parts ( 63 ), the other end bypassing the small sheaf ( 483 ) at the front section of the left side, is attached to the left-hand front section of the shoulder ( 54 ) of the pedal ( 50 ). The fourth wire ( 68 ), with one end attached to the right end of the second elastic parts ( 63 ), the other end bypassing the small sheaf ( 484 ) at the front section of the right side, is attached to the right-hand front section of the shoulder ( 54 ) of the pedal ( 50 ). Under normal conditions, the shoulder ( 54 ) of the pedal ( 50 ) nearly reaches the bottom of the inner wall ( 43 ). 
   The pedal lever ( 70 ) is connected to the bottom of the outer cylinder ( 10 ), and the rear end is connected to the bottom of the link ( 71 ), and the top of the link ( 71 ) is connected to the rear end of the top cover ( 40 ). 
   As indicated in  FIG. 19 , a garbage bag ( 80 ) has been placed between the inner cylinder ( 20 ) and the top cylinder ( 30 ), just like general garbage can. The user stepping down the front-end of the trample rod ( 70 ) is able to open the top cover ( 40 ) and discard the garbage inside the garbage can. 
   When the garbage reaches roughly 70 or 80 percent of the garbage can, as shown in  FIG. 20 , the user can step into the trample trough of the pedal ( 50 ), and then step down with force. The force applied by the user can lengthen the first elastic parts ( 61 ) and the second elastic parts ( 63 ). As shown in  FIG. 21 and 22 , the pedal ( 50 ) can fall, thus enabling the compression of the garbage to be able to hold more garbage. 
   When the foot is lifted, the first elastic parts ( 61 ) and the second elastic parts ( 63 ) will no longer be compressed, as its restoration will return the pedal ( 50 ) to its original position. 
   Installing a metal sheet ( 56 ) at the bottom of the pedal ( 50 ) will prevent the user&#39; 2 s foot from injury by sharp objects, such as glass or iron nails etc. while being trampled upon. 
   In practice, the top cylinder ( 30 ) can be directly inserted into the outer cylinder ( 10 ) instead of using the inner cylinder ( 20 ). 
   While the invention has been described with reference to the preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
