Auxiliary cleaning tool of vacuum cleaner

Abstract

An auxiliary cleaning tool of a vacuum cleaner convenient to maintain and capable of being easily switched to a cleaning mode by simple manipulation. The auxiliary cleaning tool comprises a cleaning tool body and pivoting means. The cleaning tool body is disposed on a manipulation handle of the vacuum cleaner to be moved between a cleaning mode in which the cleaning tool body advances and a standby mode in which the cleaning body retreats. The cleaning tool body has a pair of cleaning tool members which are formed by symmetrically cutting a portion of the cleaning tool body of a cylinder shape along a longitudinal direction to define wedge-shaped recesses, each recess being gradually narrowed from one side to the other side of the cleaning tool body. The cleaning tool members are connected to each other by hinge pins and pivot about the hinge pins to open and close. The pivoting means is for switching the cleaning tool body between the cleaning mode and the standby mode. In the cleaning mode, the pivoting means pivots to close to have one end narrowed in diameter, and in the standby mode, the pivoting means pivots to open to have one end extended in diameter.

What is clammed is:  
     
         1 . An auxiliary cleaning tool of a vacuum cleaner, comprising: 
 a cleaning tool body disposed on a manipulation handle of the vacuum cleaner to be moved between a cleaning mode in which the cleaning tool body advances and a standby mode in which the cleaning body retreats,    the cleaning tool body having a pair of cleaning tool members which are formed by symmetrically cutting a portion of the cleaning tool body of a cylinder shape along a longitudinal direction to define wedge-shaped recesses, each recess being gradually narrowed from one side to the other side of the cleaning tool body,    the cleaning tool members being connected to each other by hinge pins and pivoting about the hinge pins to open and close; and    pivoting means for switching the cleaning tool body between the cleaning mode and the standby mode, in the cleaning mode the pivoting means pivoting to close to have one end narrowed in diameter, and in the standby mode the pivoting means pivoting to open to have one end extended in diameter.    
     
     
         2 . The auxiliary cleaning tool of  claim 1 , wherein the pivoting means comprises: 
 two pairs of guide protrusions, one guide protrusion in each pair being disposed in a rear portion of the cleaning tool member oppositely to the counter part guide protrusion in a symmetrical manner; and    a slider connected with the cleaning tool body through the two pairs of guide protrusions, and having two pairs of guide holes corresponding to the guide protrusions to guide the movements of the guide protrusions, each pair of the guide holes being formed in an inclined manner so that a distance therebetween becomes gradually broader towards the rear portion.    
     
     
         3 . The auxiliary cleaning tool of  claim 2 , wherein each hinge pin is disposed at a position that is distanced from a front end of the cleaning tool member backward as much as ⅘ length of the cleaning tool member.
