Abstract

A carpet sweeper comprises a housing, brushes, wheels fixed to the housing, and a pivotable handle attached to the housing. The housing contains a plurality of sides, one of which is a flip-down door. The door has hinges along a bottom edge. The top edge comprises a tab which cooperates with the top of the housing to selectively secure the door in a closed position. The tab is selectively manually deformable outwardly and downwardly from the top of the housing to swing the door into an open position. The housing includes flanges to secure the trays within the housing.

Claims

1. A carpet sweeper comprising:

a housing having a plurality of sides, one of said sides comprising a flip-down door, said door having top and bottom edges, said bottom edge being hingedly affixed to said housing, said top edge comprising a tab, said tab cooperating with said housing to secure said door in a closed position, means in said housing to collect dust from a sweeping means, said door selectively swingable outwardly from said housing about said hinged bottom edge to an open position to provide for discharge of dust from said collecting means; and

,

a pivoting handle having a lower end attached to said housing.

2. The carpet sweeper as in claim 1 wherein said door is selectively swingable outwardly from said housing by manually elastically deforming said tab outwardly from said housing.

3. The carpet sweeper as in claim 1 further comprising:

a bumper around said side surfaces of said housing, said bumper extending about each side surface of said housing including said door.

4. The carpet sweeper of claim 1 wherein said collecting means comprises:

a tray slidably mounted in said housing and being selectively removable from said housing, said tray being removable through an opening in said housing created by swinging said door to said open position.

5. The carpet sweeper of claim 4 further comprising:

tabs on an interior surface of said door, said tabs securing said tray within said housing when said door is in said closed position.

6. The carpet sweeper of claim 1 wherein said housing further comprises:

a top, said top having a recess to selectively receive said tab.

7. The carpet sweeper of claim 6 wherein said recess comprises:

a shelf, said shelf having a top surface disposed inwardly of said top of said housing a distance approximately equal to a wall thickness of said tab.

8. The carpet sweeper of claim 6 wherein said recess comprises:

a shelf, said shelf being closer to an outer surface of said top than said recess.

9. The carpet sweeper of claim 8 wherein said recess selectively receives a user'"'"'s fingers when the user is manually deflecting said tab outwardly.

10. The carpet sweeper of claim 6 wherein said recess comprises:

a shelf, said shelf having a ledge protruding upwardly from a top surface of said shelf, said shelf selectively received in a slot in said tab.

11. A carpet sweeper comprising:

a housing, said housing having a plurality of sides, a top, and a base, one of said sides being a door, said housing having a first central flange extending downwardly from an inner surface of said housing and extending perpendicularly to said door, a vertical extension extending upwardly from said base;

a second central flange extending downwardly from said inward surface of said housing, said second central flange being spaced from and parallel to said first central flange, said central flanges receiving therebetween said vertical extension from said base;

a sweeping means;

a means in said housing to collect dust from said sweeping means;

said first central flange, said second central flange, and said vertical extension acting in combination to secure said collecting means;

a removable slide tray, said tray being selectively removable from said housing through said door, said tray having inner and outer side walls and first and second end walls, when said tray is within said housing said first central flange fitting adjacent said inward side wall; and

,

a pivotable handle connected to said top of said housing.

12. The carpet sweeper of claim 11 wherein said base has a lip formed by an end wall, said lip abutting a wall of said recess and securing said tray within said housing so that said housing may be tilted to empty said slide tray.

13. A carpet sweeper comprising:

a housing, said housing having a plurality of sides, a top, and a base, one of said sides being a door, said housing having a peripheral flange extending downwardly from an inner surface of said housing and extending generally perpendicularly to said door;

a sweeping means;

a means in said housing to collect dust from said sweeping means;

a dust tray slidably mounted in said housing, said dust tray being removable from said housing through said door, said dust tray having inner and outer side walls and distal and proximate end walls, when said dust tray is within said housing, said peripheral flange being located adjacent an interior surface of said dust tray outer side wall to secure said dust tray within said housing.

14. The carpet sweeper of claim 13 wherein said peripheral flange is spaced from and generally parallel to a first side of said housing, and wherein said dust tray outer side wall is received between said first side of said housing and said peripheral flange.

15. The carpet sweeper of claim 13 wherein said base has a lip formed by an end wall, said lip abutting a wall of said recess and securing said tray within said housing so that said housing may be tilted to empty said slide tray.

16. The carpet sweeper of claim 13 further comprising:

a pivotable handle connected to said top of said housing.
