Upright type vacuum cleaner

Abstract

An upright vacuum cleaner comprises a cleaner body pivotably connected to a suction port assembly, plural locking recesses 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 one or more locking recesses when the cleaner body rotates. The locking recesses comprise 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. Accordingly, even when the cleaner body is in a position parallel to the surface to be cleaned for a long time, the resilient support portion of the resilient pedal is prevented from being deformed permanently.

What is claimed is:  
     
         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;    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,    the at least one locking recess comprising 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.    
     
     
         2 . The upright type vacuum cleaner of  claim 1  wherein the at least one locking recess further comprises: 
 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.  
 
     
     
         3 . 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.  
 
     
     
         4 . The upright type vacuum cleaner of  claim 3  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.  
     
     
         5 . The upright type vacuum cleaner of  claim 4  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.
