Abstract
A blower apparatus is driven by a drive motor and has an intake opening and a discharge opening. The blower apparatus has a handle for guiding the blower apparatus with the handle being mounted on the blower apparatus such that it is pivotable from a first position into at least a second position. The blower apparatus is configured such that, during operation of the blower apparatus, an air flow passes through the discharge opening in a discharge direction. The handle has a grip region, which, in the first position, is inclined differently with respect to the discharge direction compared with the second position.
Claims15
A blower apparatus comprising:
- a fan;
- a drive motor driving said fan;
- an intake opening and a discharge opening;
- a handle for guiding said blower apparatus;
- said handle being mounted on said blower apparatus so as to permit pivoting said handle from a first position into at least a second position;
- said handle defining a grip region;
- said blower apparatus being configured to cause an air flow to pass said discharge opening in a discharge direction during operation of said blower apparatus;
- said grip region being inclined relative to said discharge direction at a first inclination in said first position and at a second inclination in said second position different than said first inclination;
- said grip region defines a longitudinal axis;
- said longitudinal axis is orientated in a direction of a first direction vector in said first position;
- said longitudinal axis is orientated in a direction of a second direction vector in said second position;
- said air flow passes said discharge opening in a direction of a third direction vector arranged at said discharge opening;
- a first angle (α) is measured from said third direction vector to said first direction vector in the direction of said grip region;
- a second angle (β) is measured from said third direction vector to said second direction vector in the direction of said grip region;
- and,
- said first angle (α) is greater than said second angle (β).
A blower apparatus comprising:
- a fan;
- a drive motor driving said fan;
- an intake opening and a discharge opening;
- a handle for guiding said blower apparatus;
- said handle being mounted on said blower apparatus so as to permit pivoting said handle from a first position into at least a second position;
- said handle defining a grip region;
- said blower apparatus being configured to cause an air flow to pass said discharge opening in a discharge direction during operation of said blower apparatus;
- said grip region being inclined relative to said discharge direction at a first inclination in said first position and at a second inclination in said second position different than said first inclination;
- wherein said handle is pivotable about a pivot axis;
- said air flow passes said discharge opening in a direction of a third direction vector arranged at said discharge opening;
- wherein said pivot axis is orientated in a direction of a fourth direction vector;
- said fourth direction vector points at least partially in a direction from said discharge opening to said handle;
- a third angle (γ) between said third direction vector and said fourth direction vector lies in a range of 90°<γ<180°;
- and,
- said third angle (γ) is measured from said third direction vector in the direction of said grip region.
