Abstract

A hand-held vacuum cleaner including a housing having mating first and second half housing elements. The housing has a handle and a nozzle. A motor is mounted within the housing for driving a shaft. A fan is mounted on the shaft for rotation therewith. A selectively separable bag assembly is mounted on the housing. A working air channel is defined within the housing communicating the nozzle with the bag assembly. The bag assembly includes a collar, a dirty air collector bag attached to the collar, and a combination latch and handle member pivotally connected to the collar. The housing includes a wall member for receiving the collar of the bag assembly and a detent member for holding the latch and handle member in a locking position when the member is pivoted into engagement therewith for securing the bag assembly onto the wall member of the housing.

Claims

1. A hand-held vacuum cleaner including a housing comprising mating first and second half housing elements, said housing having a handle and a nozzle, a motor mounted within the housing for driving a shaft, a fan mounted on said shaft for rotation therewith, a selectively separable bag assembly mounted on said housing, means defining a working air channel within said housing communicating said nozzle with said bag assembly, said bag assembly including a collar, a dirty air collector bag attached to said collar and a combination latch and handle member pivotally connected to said collar, said housing including a wall member for receiving said collar of said bag assembly and a detent member for holding said latch and handle member in a locked position when the member is pivoted into engagement therewith for securing said bag assembly onto said wall member of said housing.

2. A hand-held vacuum cleaner in accordance with claim 1 wherein said latch and handle member is disengaged from said detent member for removing said bag assembly from said wall member, said latch and handle member being pivoted into a position for grasping by the user of the vacuum cleaner for carrying the bag assembly.

3. A hand-held vacuum cleaner in accordance with claim 2 wherein said collar includes an axially extending finger and said housing includes an indented portion having a complimentary shape to said finger, said finger extending within said indented portion when said collar is positioned on said wall member.

4. A hand-held vacuum cleaner in accordance with claim 3 wherein said wall member includes a radially extending cam member in axial alignment with said indented portion of said housing, the inside surface of said collar contacting said cam member as said collar is placed on said wall member, said cam member providing a force to direct said finger of said collar into said indented portion of said housing.

5. A hand-held vacuum cleaner in accordance with claim 1 wherein said collar includes an axially extending finger and said housing includes an indented portion having a complimentary shape to said finger, said finger extending within said indented portion when said collar is positioned on said wall member.

6. A hand-held vacuum cleaner in accordance with claim 5 wherein said wall member includes a radially extending cam member in axial alignment with said indented portion of said housing, the inside surface of said collar contacting said cam member as said collar is placed on said wall member, said cam member providing a force to direct said finger of said collar into said indented portion of said housing.

7. A hand-held vacuum cleaner in accordance with claim 1, wherein said wall member includes a radially extending cam member, the inside surface of said collar contacting said cam member as said collar is placed on said wall member, said cam member producing a force to accurately position said collar on said wall member.

8. A bag assembly for a hand-held vacuum cleaner comprising a collar, a dirty air collector bag attached to said collar and a combination latch and handle member pivotally connected to said collar, said member being operable in a first position for engaging a detent mechanism on said cleaner for releasably latching said bag assembly on said cleaner and being operable in a second position for grasping by the user of the vacuum cleaner for carrying said bag assembly.

9. A bag assembly in accordance with claim 8 wherein said collar comprises a pair of axially extending and relatively concentric flange-like members, with the space between the opposed surfaces of said flange-like members narrowing in a first direction, said bag being placed over the outer surface of the inner of the flange-like members, with the material defining the open end of the bag extending into said space towards the first direction.
