Cane

Abstract

A cane includes a rod, a primary handle, a ring, an auxiliary handle and a skid-proof device. The rod includes a first end for contact with the ground. The primary handle extends from a second end of the rod. The ring is provided on the rod in a rotatable and movable manner. The auxiliary handle extends from the ring. The skid-proof device is provided between the rod and the ring. The skid-proof device includes annular ribs on an internal side. A diameter of the annular ribs is at least equal to a diameter of the rod. The auxiliary handle is rotatable about and movable along an axis of the rod due to little friction between the rod and the annular ribs as the auxiliary handle is not pivoted toward the first end of the rod. The auxiliary handle is locked on the rod due to friction between the rod and the annular ribs as the auxiliary handle is pivoted toward the first end of the rod.

1 . A cane comprising:
 a rod ( 10 ) including a first end for contact with the ground;   a primary handle ( 16 ) extending from a second end of the rod ( 10 );   a ring ( 25 ) provided on the rod ( 10 ) in a rotatable and movable manner;   an auxiliary handle ( 20 ) extending from the ring ( 25 ); and   a skid-proof device ( 30 ) provided between the rod ( 10 ) and the ring ( 25 ), wherein the skid-proof device ( 30 ) comprises annular ribs ( 33 ,  37 ) on an internal side, wherein a diameter of the annular ribs ( 33 ,  37 ) is at least equal to a diameter of the rod ( 10 ), wherein the auxiliary handle ( 20 ) is rotatable about and movable along an axis of the rod ( 10 ) due to little friction between the rod ( 10 ) and the annular ribs ( 33 ,  37 ) as the auxiliary handle ( 20 ) is not pivoted toward the first end of the rod ( 10 ), wherein the auxiliary handle ( 20 ) is locked on the rod ( 10 ) due to friction between the rod ( 10 ) and the annular ribs ( 33 ,  37 ) as the auxiliary handle ( 20 ) is pivoted toward the first end of the rod ( 10 ).   
     
     
         2 . The cane according to  claim 1 , wherein the rod ( 10 ) is a telescopic element with an adjustable length. 
     
     
         3 . The cane according to  claim 1 , further including a soft sleeve ( 21 ) provided on the auxiliary handle ( 20 ) 
     
     
         4 . The cane according to  claim 1 , wherein the skid-proof device ( 30 ) includes two skid-proof elements ( 31 ,  35 ) spaced from each other along a transverse direction of the rod ( 10 ) by two gaps and provided between the rod ( 10 ) and the ring ( 25 ), wherein each of the skid-proof elements ( 31 ,  35 ) includes arched ribs ( 33 ,  37 ) on an internal side, wherein each of the arched ribs ( 33 ) of one of the skid-proof elements ( 31 ) and a related one of the arched ribs ( 37 ) of the other skid-proof element ( 35 ) together become one of the annular ribs ( 33 ,  37 ). 
     
     
         5 . The cane according to  claim 4 , wherein the ring ( 25 ) includes an annular groove ( 27 ) defined in an internal side while each of the skid-proof elements ( 31 ,  35 ) includes an arched flange ( 32 ,  36 ) formed on an external side and inserted in the annular groove ( 27 ), avoiding the movement of the ring ( 25 ) relative to the skid-proof elements ( 31 ,  35 ) along the axis of the rod ( 10 ). 
     
     
         6 . The cane according to  claim 5 , wherein the ring ( 25 ) includes on an internal side an annular flange ( 28 ) for abutment against a lower end of each of the skid-proof elements ( 31 ,  35 ), avoiding downward movement of the skid-proof elements ( 31 ,  35 ) relative to the ring ( 25 ) along the axis of the rod ( 10 ). 
     
     
         7 . The cane according to  claim 1 , wherein one of the ring ( 25 ) and the skid-proof device ( 30 ) includes an annular groove ( 27 ) while the other one of the ring ( 25 ) and the skid-proof device ( 30 ) includes an arched flange ( 32 ,  36 ) inserted in the annular groove ( 27 ), thus avoiding the movement of the ring ( 25 ) relative to the skid-proof device ( 30 ) along the axis of the rod ( 10 ). 
     
     
         8 . The cane according to  claim 1 , wherein the ring ( 25 ) includes an annular groove ( 27 ) defined in an internal side while the skid-proof device ( 30 ) includes an annular flange ( 32 ,  36 ) formed on an external side and inserted in the annular groove ( 27 ), avoiding the movement of the ring ( 25 ) relative to the skid-proof device ( 30 ) along the axis of the rod ( 10 ). 
     
     
         9 . The cane according to  claim 8 , wherein the ring ( 25 ) includes on an internal side an annular flange ( 28 ) for abutment against a lower end of the skid-proof device ( 30 ), avoiding downward movement of the skid-proof device ( 30 ) relative to the ring ( 25 ) along the axis of the rod ( 10 ). 
     
     
         10 . The cane according to  claim 1 , wherein the primary handle ( 16 ) includes an axis in perpendicular to the axis of the rod ( 10 ). 
     
     
         11 . The cane according to  claim 1 , wherein the auxiliary handle ( 20 ) includes an axis in perpendicular to the axis of the rod ( 10 ).
