Apparatus of driving agitator of upright vacuum cleaner

An apparatus of driving an agitator of an upright vacuum cleaner, the apparatus comprising:

• a driving shaft roller installed at an end of a motor of the vacuum cleaner, around which a power transmission member is wound intermittently;
• a bushing installed on an outer circumference of the driving shaft roller coaxially with a driving shaft;
• a fixing panel inserted onto the bushing;
• a selection lever rotating about a lever hole hinge-coupled to the fixing panel by an external force caused by a user;
• a selection link whose one end is hinge-coupled to the body of the selection lever;
• a rotational driving part including a rotation guide which is shaped in a circular skirt and into which a bushing is inserted and rotated, a support sphere formed extending in a direction of an axis parallel with the driving shaft roller on an outer circumference of the rotation guide and coupled with one end of the selection link, and a roller support part formed extending in an opposite direction to the support sphere;
• an idle roller which is inserted onto an outer circumference of the roller support part and around which the power transmission member is wound intermittently due to a self-rotation of the entire rotational driving part such that a power transmission is controlled;
• and
• a stop means for maintaining a position which is determined by the self-rotation of the rotational driving part.

An apparatus of driving an agitator of an upright vacuum cleaner, the apparatus comprising:

• a driving shaft roller which is connected to a motor for driving a suction fan of the vacuum cleaner and around which an elastic member is selectively wound;
• a bushing installed on an outer circumference of the driving shaft roller coaxially with a driving shaft;
• a fixing panel and a rotational driving part which are inserted into the bushing and fixed;
• a support sphere and a roller support part which are formed in a direction of an axis parallel with the driving shaft roller on an outer circumference of the rotational driving part;
• a manipulating means connected with the support sphere, for manipulating the rotational driving part;
• an idle roller which is inserted into the roller support part and around which an elastic member is wound;
• and
• a stop means for maintaining a position of the rotational driving part stably.

An apparatus of driving an agitator of an upright vacuum cleaner, the apparatus comprising:

• a driving shaft roller extending from the vacuum cleaner;
• a fixing panel and a rotation guide which are positioned outside the driving shaft roller and guided coaxially with the driving shaft roller;
• a support sphere and a roller support part which are formed in a direction of an axis parallel with the driving shaft roller on an outer circumference of the rotation guide;
• an idle roller which is inserted into the roller support part;
• a manipulating means connected with the support sphere, for manipulating the rotation guide so that the elastic member is selectively wound around the driving shaft roller or the idle roller;
• and
• a stop means for maintaining a position of the rotational driving part stably.
