Handle structure

Abstract

The invention provides a handle structure for a user to carry/drag an object. Furthermore, the object has a cavity on a surface thereof for accommodating the handle structure. In addition, the handle structure includes a first base, a second base, a first supporting portion, a second supporting portion, and a handle portion. When the user carries/drags the object through the handle structure, the first supporting portion, the second supporting portion, and the handle portion are capable of rotating with respect to the object; furthermore, the handle portion is capable of rotating with respect to the first supporting portion and the second supporting portion.

     wherein the first supporting portion and the second supporting portion are capable of rotating with respect to the object, and the handle portion being capable of rotating with respect to the first supporting portion and the second supporting portion; 
     wherein when the handle structure is not used, the handle structure being capable of fitting within the cavity without protruding out of the surface of the object. 
   
   
       2 . The handle structure of  claim 1 , further comprising:
 a first fixing plug, passing through the first spindle bore of the first supporting portion, for fixing the first axle of the handle portion in the first spindle bore; and   a second fixing plug, passing through the second spindle bore of the second supporting portion, for fixing the second axle of the handle portion on the second spindle bore.   
   
   
       3 . The handle structure of  claim 1 , wherein the second end of the first supporting portion has a first clasp portion and the fourth end of the second supporting portion has a second clasp portion, the first supporting portion clasping the first shaft by the first clasp portion, and the second supporting portion clasping the second shaft by the second clasp portion. 
   
   
       4 . The handle structure of  claim 1 , wherein the first base and the second base are mounted on the first surface respectively by an adhesive material. 
   
   
       5 . The handle structure of  claim 1 , wherein the first base and the second base are mounted on the first surface respectively by at least one screw. 
   
   
       6 . The handle structure of  claim 1 , wherein the handle structure is made of plastic material. 
   
   
       7 . The handle structure of  claim 1 , wherein the distance between the first base and a center of gravity of the object is substantially equal to the distance between the second base and the center of gravity of the object. 
   
   
       8 . The handle structure of  claim 1 , wherein the object is one selected from the group consisting of: a box, a trunk, a barrel, and a cabinet. 
   
   
       9 . A handle structure for a user to carry/drag an object, the handle structure comprising:
 a first base, having a first basic portion and a first shaft, the first basic portion being used to mount the handle structure on a first surface of the object;   a second base, having a second basic portion and a second shaft, the second basic portion being used to mount the handle structure on the first surface of the object;   a first supporting portion, having a first end and a second end opposite to the first end, the first end having a first spindle bore, and the second end being rotatably jointed to the first shaft;   a second supporting portion, having a third end and a fourth end opposite to the third end, the third end having a second spindle bore, and the fourth end being rotatably jointed to the second shaft; and   a handle portion, having a fifth end and an sixth end opposite to the fifth end, the fifth end having a first axle rotatably jointed to the first spindle bore, and the sixth end having a second axle rotatably jointed to the second spindle bore;   
     wherein when the user carries/drags the object with the handle structure, the first supporting portion and the second supporting portion are capable of rotating suitably with respect to the object, and the handle portion is capable of rotating suitably with respect to the first supporting portion and the second supporting portion. 
   
   
       10 . The handle structure of  claim 9 , further comprising;
 a first fixing plug, passing through the first spindle bore of the first supporting portion, for fixing the first axle of the handle portion; and   a second fixing plug, passing through the second spindle bore of the second supporting portion, for fixing the second axle of the handle portion.   
   
   
       11 . The handle structure of  claim 9 , wherein the second end of the first supporting portion has a first clasp portion, and the fourth end of the second supporting portion has a second clasp portion, the first supporting portion clasping the first shaft by the first clasp portion, and the second supporting portion clasping the second shaft by the second clasp portion. 
   
   
       12 . The handle structure of  claim 9 , wherein the first surface of the object is a bottom surface of a cavity, and the cavity being located on a second surface of the object, wherein when the handle structure is not used, the handle structure being capable of fitting within the cavity without protruding out of the second surface of the object. 
   
   
       13 . The handle structure of  claim 9 , wherein the first base and the second base are mounted on the first surface respectively by an adhesive material. 
   
   
       14 . The handle structure of  claim 9 , wherein the first base and the second base are mounted on the first surface respectively by at least one screw.
