Abstract

A vacuum assisted broom for sweeping floors having a sweeping member, preferably in the form of a plurality of stiff bristles, for bi-directional sweeping of the floor. The sweeping member is operatively mounted within a housing member, which housing member partially encloses the sweeping member within its hollow interior such that the bristles depend from the housing member through a first opening. A handle member is securely attached to the housing member and extends upwardly therefrom. The sweeping member is moveable between a first extended position the bristles are extended sufficiently that the broom may be used as a conventional broom, and a second retracted position where the sweeping member is substantially retracted into the housing member, with only a short end portion of the bristles extending outwardly from the housing member. The housing member narrows at its first opening so as to generally surround and confine the bristles so as to preclude lateral movement thereof, thus providing a broom with very short stiff relatively movable bristles. The sweeping member automatically latches in its second retracted position. When the sweeping member is in its second retracted position, an electrical switch is actuated so as to turn on a suction means that is operatively connected to the interior of the housing member, thus to create a partial vacuum at the first opening of the housing member. In this manner, the vacuum assisted broom of the present invention can be used as conventional sweeping broom and also can be used to subsequently vacuum up any dust or dirt swept to a central location by the broom.

Claims

1. A vacuum assisted broom for sweeping a sweepable surface, said broom comprising:

a housing member having interconnected front, rear and side wails defining a hollow interior and being shaped and dimensioned to generally surround at least the top portion of a sweeping member;

a handle member securely attached to said housing member and extending upwardly therefrom;

a selectively actuatable suction means operatively connected to said housing member by way of a second opening in said housing member such that said hollow interior is in fluid communication with said suction means so as to thereby create a partial vacuum at said first opening; and

a sweeping member movably mounted within said housing member so as to depend therefrom through a first opening in said housing member, for selective movement between a first extended position whereat said sweeping member extends outwardly from said first opening in said housing member to thereby permit the sweeping of said sweepable surface using a broom-like sweeping action, and a second retracted position whereat said sweeping member is substantially reacted into said housing member so as to allow said first opening in said housing member to be in close proximity to said sweepable surface, to thereby permit vacuuming of debris frown said sweepable surface, upon actuation of said suction means.

2. The vacuum assisted broom of claim 1, further comprising switch means operatively mounted between said housing member and said sweeping member, said switch means actuatable by way of the change in positioning of said sweeping member between said first extended position and said second retracted position so as to thereby cause selective actuation of said suction means.

3. The vacuum assisted brook of claim 1, wherein said sweeping member comprises a plurality of broom bristles.

4. The vacuum assisted broom of claim 1, further comprising a selectively closable front inlet located between said sweeping member and the front wall of said housing member and a selectively closable rear inlet located between said sweeping member and the rear wall of said housing member, with said sweeping member operatively mounted for movement between a forward position whereat said rear inlet is fully open so as to permit the passage of air and debris therethrough and said front inlet is substantially closed so as to preclude the passage of air and debris therethrough, and a rearward position whereat said front inlet is fully open so as to permit the passage of air and debris therethrough and said rear inlet is substantially closed so as to preclude the passage of air and debris therethrough.

5. The vacuum assisted broom of claim 4, wherein said sweeping member is pivotally mounted with respect to said housing member.

6. The vacuum assisted broom of claim 1, wherein said handle member is an elongate broom handle.

7. The vacuum assisted broom of claim 1, further comprising a plurality of leg members depending from the bottom of said housing member, said leg members positioned so as to contact said sweepable surface and shaped and dimensioned to preclude the bottom of said housing member from contacting said sweepable surface, thus creating a gap between said sweepable surface and the bottom of said housing member, said gap suitable for allowing passage of debris therethrough.

8. The vacuum assisted broom of claim 7, wherein said leg members depend from the bottom area of said from and rear wails of said housing member.

9. The vacuum assisted broom of claim 8, wherein each leg member has a wheel member rotatably attached thereto so as to extend below said leg member, to thereby be adapted for rolling contact with said sweepable surface.

10. The vacuum assisted broom of claim 1, further comprising a plurality of leg members depending from the bottom of said housing member, said leg members positioned so as to contact said sweepable surface and shaped and dimensioned to preclude the bottom of said housing member from contacting said sweepable surface, thus creating a gap between said sweepable surface and the bottom of said housing member, said gap sintable for allowing the passage of debris therethrough.

11. The vacuum assisted broom of claim 1, wherein said sweeping member is spring biased towards said first extended position by way of a biasing spring.

12. The vacuum assisted broom of claim 11, further comprising a latching means operatively connected between said housing member and said sweeping member to thereby cause said sweeping member to be releasably latchable in said second retracted position.

13. The vacuum assisted broom of claim 12, wherein said latching member automatically releasably latches said sweeping member in said second retracted position when said sweeping member reaches said second retracted position.

14. The vacuum assisted broom of claim 13, wherein said sweeping member is movable from said first extended position to said second retracted position by way of pressing said sweeping member against said sweepable surface.

15. The vacuum assisted broom of claim 14, wherein said latching means is released so as to permit said sweeping member to move from its second retracted position to its first extended position, as biased by said biasing spring, by way of pressing said sweeping member against said sweepable surface.

17. The vacuum assisted broom of claim 1, further comprising switch means operatively mounted between said housing member and said leg member, said switch means being actuated upon change in position said sweeping member from said first extended position to said second retracted position as to thereby cause corresponding actuation of said suction means, and being deactuated upon change in position of said sweeping member from said second retracted position to said first extended position so as to thereby cause corresponding deactuation of said suction means.

16. A broom for sweeping a sweepable surface, said broom comprising:

a housing member having interconnected front, rear and side walls defining a hollow interior and being shaped and dimensioned to generally surround at least a top portion of a sweeping member;

a handle member securely attached to said housing member and extending upwardly therefrom; and

a sweeping member movably mounted within said housing member so as to extend outwardly therefrom through a first opening in said housing member and movable between a first extended position whereat said sweeping member extends outwardly from said first opening in said housing member to thereby permit the sweeping of said sweepable surface using a broom-like sweeping action and a second retracted position whereat said sweeping member is substantially retracted into said housing member such that only a small end portion of said sweeping member extends outwardly therefrom through said first opening, and further such that said front and rear walls of said housing member closely surround said sweeping member to thereby restrict the relative lateral movement of said sweeping member with respect to said housing member, thus permitting a substantially more stiff sweeping action.
