Vacuum cleaner with power cord support

Abstract

A vacuum cleaner for improving user convenience. The vacuum cleaner includes a cleaner body connected with a suction brush, and a power cord holding device rotatably disposed on the cleaner body. The power cord holding device rotates between a first position to stow or use the vacuum cleaner and a second position to allow a user to wind a power cord after use of the vacuum cleaner.

1 . A vacuum cleaner comprising: 
 a cleaner body connected with a suction brush; and    a power cord holding device rotatably coupled to the cleaner body,    the power cord holding device being pivotable between a first stow position adjacent the cleaner body, and a second wind position remote from the suction brush allowing a user to wind a power cord on the power cord holding device.    
   
   
       2 . The vacuum cleaner as claimed in  claim 1 , wherein the power cord holding device is disposed on a side surface of the cleaner body and pivots on a pivoting axis.  
   
   
       3 . The vacuum cleaner as claimed in  claim 2 , wherein the power cord holding device comprises: 
 a power cord winding plate around which the power cord is wound;    a first power cord support pin assembly disposed adjacent to the pivoting axis of the power cord winding plate; and    a second power cord support pin assembly disposed on the other end of the power cord winding plate opposite to the first power cord support pin assembly.    
   
   
       4 . The vacuum cleaner as claimed in  claim 3 , wherein the first power cord support pin assembly comprises: 
 a first support pin seating portion formed in the power cord winding plate;    a fixing boss protruding from a center of the first supporting pin seating portion;    a first power cord support pin having a first penetrating hole defined in a center corresponding to the fixing boss, the first power cord support pin rotatably mounted in the first support pin seating portion; and    a first elastic member having one end supported on a bottom of the first power cord support pin through which the fixing boss penetrates, and the other end supported by the washer.    
   
   
       5 . The vacuum cleaner as claimed in  claim 4 , wherein the first power cord support pin assembly further comprises: 
 at least one fixing recess formed on an outer circumference of the first support pin seating portion; and    at least one fixing protrusion formed on the first power cord supporting pin corresponding to the fixing recess of the first power cord supporting pin,    wherein when the first power cord support pin is pulled out, the fixing protrusion releases from the fixing recess such that a locking is released.    
   
   
       6 . The vacuum cleaner as claimed in  claim 4 , wherein the pivoting axis of the power cord winding plate is formed on the opposite side of the first power cord support pin seating portion and inserted in the cleaner body.  
   
   
       7 . The vacuum cleaner as claimed in  claim 6 , wherein a locking ring is disposed around an outer circumference of the pivoting axis, and a ring receiving recess is formed in an insertion recess of the cleaner body in which the pivoting axis is received, the locking ring being received in the ring receiving recess.  
   
   
       8 . The vacuum cleaner as claimed in  claim 1 , further comprising a fixing device to fix the power cord holding device to the cleaner, the fixing device comprises a first locking unit to fix the power cord holding device at the second position, and a second locking unit to fix the power cord holding device at the first position.  
   
   
       9 . The vacuum cleaner as claimed in  claim 8 , wherein the first locking unit comprises: 
 a first press button assembly disposed on the power cord winding plate; and    a first pop-up protrusion assembly formed in the cleaner body and fitted in the first press button assembly when the power cord holding device rotates to the second position.    
   
   
       10 . The vacuum cleaner as claimed in  claim 9 , wherein the first press button assembly comprises: 
 a first press button seating portion disposed in the power cord winding plate and having a second penetrating hole which is defined in a center thereof and penetrates through the power cord winding plate;    a first press button seated in the first press button seating portion;    a second elastic member having one end supported on a bottom of the first press button seating portion and the other end supported on the first press button; and    at least one first hook and at least one first hook receiving recess which are formed on the first press button and the first press button seating portion, respectively, to correspond to each other.    
   
   
       11 . The vacuum cleaner as claimed in  claim 8 , wherein the first pop-up protrusion assembly comprises: 
 a protrusion seating recess depressed in the cleaner body;    a pop-up protrusion being movable upwardly and downwardly in the protrusion seating recess;    a third elastic member having one end supported on a bottom of the protrusion seating recess and the other end fitted in the first pop-up protrusion; and    a support plate to prevent the first pop-up protrusion from escaping from the protrusion seating recess.    
   
   
       12 . The vacuum cleaner as claimed in  claim 8 , wherein the second locking unit comprises: 
 a second power cord support pin assembly disposed in the power cord winding plate; and    a second pop-up protrusion assembly formed in the cleaner body and fitted in the second power cord support pin assemlby when the power cord holding device moves to the first position.    
   
   
       13 . The vacuum cleaner as claimed in  claim 12 , wherein the second power cord support pin assembly comprises: 
 a second press button seating portion disposed in the power cord winding plate and having a third penetrating hole which is defined in a center thereof and penetrates through the power cord winding plate;    a second power cord support pin integrally formed with the second press button seating portion;    a second press button movably seated in the second press button seating portion;    a fourth elastic member having one end supported on a bottom of the second press button seating portion and the other end supported on the second press button; and    at least one second hook and at least one second hook receiving recess which are formed on the second press button and the second press button seating portion, respectively, to correspond to each other.    
   
   
       14 . The vacuum cleaner as claimed in  claim 12 , wherein the second pop-up protrusion assembly comprises: 
 a protrusion seating recess depressed in the cleaner body;    a pop-up protrusion being movable upwardly and downwardly in the protrusion seating recess;    a third elastic member having one end supported on a bottom of the protrusion seating recess and the other end fitted in the pop-up protrusion; and    a support plate to prevent the pop-up protrusion from escaping from the protrusion seating recess.
