Upright type vacuum cleaner

Abstract

An upright vacuum cleaner comprises a cleaner body, plural locking recesses in the cleaner body include a parallel position recess in which the locking protrusion is locked when the cleaner body rotates to a parallel position with respect to a surface to be cleaned. Additionally, a filter removal means, prevents a filter cover from being removed when the vacuum cleaner is being operated.

1 . An upright type vacuum cleaner, comprising: 
 a suction port assembly;    a cleaner body connected to the suction port assembly, the cleaner body and the suction port assembly being freely pivotable with respect to each other,    the cleaner body comprising, 
 a frame having a duct formed at a side of the cleaner body in order to communicate with the motor driving chamber,  
 a support member protruded to a predetermined dimension from an inside wall of the duct,  
 a filter cover disposed in the duct, and  
 a removal means provided at a side of the cleaner body to open and close the filter cover;  
   at least one locking recess formed in a side of the cleaner body; and    a resilient pedal pivotably mounted on the suction port assembly and having a locking protrusion which is sequentially locked in the at least one locking recess when the cleaner body pivots with respect to the suction port assembly such that the cleaner body pivots in a stepwise manner,    wherein the at least one locking recess includes 
 a parallel position recess in which the locking protrusion of the resilient pedal is locked when the cleaner body pivots to a parallel position with respect to a surface to be cleaned,  
 an upright position recess in which the locking protrusion is locked when the cleaner body is in an upright position with respect to the surface to be cleaned; and  
 one or more inclined position recesses in which the locking protrusion is locked when the cleaner body pivots at a predetermined angle with respect to the surface to be cleaned, and  
   wherein the removal means includes 
 at least one hook formed at a front end of the filter cover; and  
 a locking hole having a locking protrusion disposed at the frame placed at a position corresponding to the position of the hook, and  
   wherein the hook includes:    a fixing portion extended from the filter cover;    a flexible pressing portion bent in a direction approximately 180° from the fixing portion; and    a pair of protrusions disposed at both sides of the flexible pressing portion for engagement with the locking protrusion of the locking hole.    
   
   
       2 . The upright type vacuum cleaner of  claim 1  wherein the resilient pedal further comprises: 
 a pedal body pivotably mounted on the suction port assembly, the pedal body comprising the locking protrusion protruding from a side toward the cleaner body and a pedal portion being subject to an external force to release the locking protrusion from the at least one locking recess; and    a resilient support portion for resiliently pressing a side of the pedal body to pivot the pedal body in a direction where the locking protrusion presses the cleaner body.    
   
   
       3 . The upright type vacuum cleaner of  claim 2 , wherein the resilient support portion further comprises a plate element integrally protruding from a lower side of the pedal body, the plate element having a bending portion to be supported by an inner wall of the suction port assembly.  
   
   
       4 . The upright type vacuum cleaner of  claim 3 , wherein the at least one locking recess has a slanted surface such that the locking protrusion is easily released from the at least one locking recess when the cleaner body pivots into the upright position.
