Abstract

A portable, battery operated cobweb vacuum cleaner is carried on a human'"'"'s back or shoulder thereby permitting use of both hands. Extension means and other parts have an effective internal diameter whereby cobwebs do not substantially adhere to internal walls. Also, the internal walls can be coated with materials which minimize the adhesion of cobwebs.

Claims

1. A portable cobweb removal vacuum apparatus comprising:

(a) means for carrying said apparatus on a human;

(b) a housing attached to said carrying means and containing;

(1) an electric motor;

(2) a blower driven by said electric motor whereby rotation of said blower produces a vacuum;

(3) a removable separation means having an intake opening for reception of solid particles and air drawn into said intake opening in response to a vacuum developed by said blower, and having a discharge area for the discharge of outgoing separated air;

(4) at least one rechargeable battery adapted to provide power for said electric motor;

(5) an on-off switch operationally connected to said motor and said battery and which switch activates and deactivates said motor;

(c) a flexible hose, having an internal coating which substantially minimizes the adhesion of cobwebs, attached to the intake opening of separation means;

(d) extension means, having an internal coating which substantially minimizes the adhesion of cobwebs;

attached to the flexible hose and having means for attaching thereto a cleaning tool; and

(e) a cleaning tool having means for attachment to said extension means.

2. Apparatus according to claim 1 wherein said rechargeable battery is removable.

3. Apparatus according to claim 1 wherein the housing additionally contains means for connecting said rechargeable battery to an external battery charger.

4. Apparatus according to claim 1 wherein the housing additionally contains a battery charger operationally attached to said rechargeable battery and containing means whereby said battery charger can be operationally attached to a power source so that when said battery charger is opertionally attached to said power source, said battery charger recharges said rechargeable battery.

5. Apparatus according to claim 1 wherein the separation means is selected from the group consisting of a cloth separation bag, a paper separation bag, and a canister.

6. A portable cobweb removal vacuum apparatus comprising:

(a) means for carrying said apparatus on a human;

(b) a housing attached to said carrying means and containing;

(1) an electric motor;

(2) a blower driven by said electric motor whereby rotation of said blower produces a vacuum;

(3) a removable separation means having an intake opening for reception of solid particles and air drawn into said intake opening in response to a vacuum developed by said blower, and having a discharge area from the discharge of outgoing separated air, and wherein the separation means is selected from the group consisting of a cloth separation bag, a paper separation bag, and a canister;

(4) at least one rechargeable battery adapted to provide power for said electric motor and wherein the housing contains means for connecting said rechargeable battery to an external battery charger;

(5) an on-off switch opertionally connected to said motor and said battery and which switch activates and deactivates said motor;

(c) a flexible hose attached to the intake opening of said separation means;

said hose having an effective internal diameter whereby cobwebs do not substantially adhere to its internal walls; and

having an internal coating which substantially minimizes the adhesion of cobwebs;

(d) extension means attached to the flexible hose and having means for attaching thereto a cleaning tool and said extension means are constructed of a strong, light weight material;

said extension means having an effective internal diameter whereby cobwebs do not substantially adhere to its internal walls; and

having an internal coating which substantially minimizes the adhesion of cobwebs; and

(e) a cleaning tool having means for attachment to said extension means, said tool having an effective internal diameter whereby cobwebs do not substantially adhere to its internal walls, and having an internal coating which substantially minimizes the adhesion of cobwebs.
