Abstract

The present invention is a vacuum cleaner and recharging assembly including a vacuum cleaner having a motor, a housing enclosing the motor, a fan driven by the motor for producing a vacuum, a canister for at least the reception of air and foreign matter drawn into the canister in response to the vacuum produced by the fan, and a power source for powering the motor. The assembly also includes a charging unit cooperable with the vacuum cleaner for charging the power source. The assembly further includes means for removably securing the vacuum cleaner to the charging unit when the vacuum cleaner engages the charging unit.

Claims

1. A vacuum cleaner and charging assembly comprising:

a vacuum cleaner including a motor, a housing enclosing said motor, and a power source for powering said motor, said housing including means forming a groove extending inwardly from the outer surface of said housing on each side thereof;

a charging unit cooperable with said vacuum cleaner for charging said power source, said charging unit including means forming a cavity extending axially through said unit, said cavity including a bottom wall and upwardly extending sidewalls from said bottom wall, said bottom and said sidewalls having a shape complementary to the outer surface of said housing;

means for removably securing said vacuum cleaner to said charging unit when said vacuum cleaner engages said charging unit; and

each of said sidewalls of said charging unit including a locking tab pivotably connected at one end and being movable between a first position in which the free end of said locking tab engages said groove and a second position in which the free end of said locking tab disengages said groove.

2. An assembly as set forth in claim 1 wherein said bottom wall has a first portion and a second portion, said first and second portions being inclined relative to each other.

3. An assembly as set forth in claim 2 wherein the bottom surface of said housing has a third portion complementary to said first portion and a fourth portion complementary to said second portion.

4. An assembly as set forth in claim 3 wherein said charging unit includes a bottom surface adapted to be supported by a support surface.

5. An assembly as set forth in claim 4 wherein said charging unit includes means extending upwardly from said bottom surface for supporting said bottom wall in spaced relation thereto.

6. An assembly as set forth in claim 5 wherein said said bottom wall forms a pivot point at one end to allow said third portion of said housing to disengage from said first portion of said bottom wall when said vacuum cleaner is pivoted by an operator to move said locking tabs to said second position.

7. A vacuum cleaner and charging assembly comprising:

a vacuum cleaner including a motor, a housing enclosing said motor, a fan driven by said motor for producing a vacuum, a canister for at least the reception of air and foreign matter drawn into said canister in response to the vacuum produced by said fan, and a power source for powering said motor;

a charging unit cooperable with said vacuum cleaner for charging said power source;

means for removably securing said vacuum cleaner to said charging unit when said vacuum cleaner engages said charging unit;

said charging unit including a bottom wall and upwardly extending side walls from said bottom wall to form a cavity, said bottom and said side walls having a shape complementary to the outer surface of said housing;

said housing including means forming a groove extending inwardly from the outer surface of said housing on each side thereof;

each of said side walls of said charging unit including a locking tab pivotally connected at one end and being moveable between a first position in which the free end of said locking tab engages said groove and a second position in which the free end of said locking tab disengages said groove; and

said bottom wall forming a pivot point at one end to allow a bottom surface of said housing to disengage from said bottom wall when said vacuum cleaner is pivoted by an operator to move said locking tabs to said second position and allow removal of said vacuum cleaner from said charging unit.
