Abstract

A weed trimmer extension device for cutting and collecting, or dispersing weeds includes a cutting enclosure, to which can be attached a collecting bag or a cutting disperser; a replacement cutting implement; and enclosure fasteners, for attaching the weed trimmer extension device to a weed trimmer. The cutting implement can further include a cutting blade and a perpendicular fin, which pushes air in a circular direction of motion, thereby creating a vortex of air, which rotates in the plane spanned out by the rotating cutting blade. The cutting enclosure covers the replacement cutting implement, which propels the cuttings, contained and directed by the cutting enclosure, into either the collecting bag or the cutting disperser, which disperses the weed cuttings over an area to the side.

Claims

1. A weed trimmer extension system for installation on a weed trimmer with a naked trimmer head, the weed trimmer extension system comprising:

a. a cutting enclosure including an ejection aperture in a side of a rear end of the cutting enclosure;

b. enclosure fasteners;

c. a replacement cutting implement;

further comprising a cutting blade, and at least one perpendicular fin, which is perpendicularly connected to the cutting blade, along a length of the cutting blade;

d. a cutting implement fastener; and

e. a protruding spacer;

wherein the cutting enclosure is configured to be attached to the naked trimmer head of the weed trimmer with the enclosure fasteners, and the cutting blade is configured to be attached to a rotatable axle of the naked trimmer head via the cutting implement fastener, such that the cutting enclosure is configured to cover the cutting blade and the at least one perpendicular fin, above and to sides of the cutting implement, such that the cutting enclosure in combination with a rotation of the cutting blade and the at least one perpendicular fin is configured to create a substantially planar air vortex that propels cuttings, which are contained and directed by the cutting enclosure, and wherein the cuttings are ejected through the ejection aperture;

wherein the cutting implement and the protruding spacer are configured to be mounted on the rotatable axle and tightened in place with the cutting implement fastener, such that the protruding spacer protrudes underneath the cutting implement, whereby the protruding spacer reduces a risk of close contact with the ground, whereby strength of the air vortex is reduced, and a risk of the cutting implement impacting ground during use is reduced.

2. The weed trimmer extension system of claim 1, wherein the cutting enclosure further comprises an ejection canal, such that the air vortex propels cuttings via the ejection canal from the cutting enclosure to the ejection aperture in the side of the cutting enclosure.

3. The weed trimmer extension system of claim 1, wherein an external protrusion of the protruding spacer is in a range of 0.5-2 inches.

4. The weed trimmer extension system of claim 1, further comprising a collection bag, wherein the collection bag is attached to the cutting enclosure, and wherein the cutting implement propels the cuttings, which are contained and directed by the cutting enclosure, through the ejection aperture and into the collecting bag.

5. The weed trimmer extension system of claim 4, wherein the collection bag further comprises at least one mesh screen, made of a mesh fabric that allows airflow, whereby air pressure is reduced when air enters the collection bag from the cutting enclosure during operation, whereby the mesh screen functions to avoid or reduce pressure accumulation in the collection bag, and allows a user to visually inspect the contents of cuttings in the collection bag.

6. The weed trimmer extension system of claim 1, further comprising a cutting disperser, wherein the cutting disperser is attached to the cutting enclosure, and the cutting implement propels cuttings, which are contained and directed by the cutting enclosure, through the ejection aperture and into the cutting disperser, which directs and disperses the cuttings to an area to a side of the weed trimmer extension system during operation.

7. The weed trimmer extension system of claim 1, wherein the ejection aperture is configured to be substantially at level with a plane of rotation of the replacement cutting implement.

8. The weed trimmer extension system of claim 1, wherein the at least one perpendicular fin further comprises at least one aperture.

9. The weed trimmer extension system of claim 1, wherein the protruding spacer further comprises:

a. a spacer aperture, from a central part of an inner end to a central part of an outer end of the protruding spacer; and

b. an inner ledge, which further comprises a central aperture;

wherein the inner ledge is attached to the protruding spacer inside the spacer aperture, whereby the axle fits through the spacer aperture and the central aperture, and the cutting implement fastener is fastened against an outer side of the inner ledge, when the cutting implement fastener is fastened to the rotatable axle.

10. A weed trimmer extension system for installation on a weed trimmer with a naked trimmer head, the weed trimmer extension system comprising:

a. a cutting enclosure including an ejection aperture in a side of a rear end of the cutting enclosure;

b. a replacement cutting implement;

c. enclosure fasteners;

d. a protruding spacer; and

e. a cutting implement fastener;

wherein the cutting enclosure is configured to be attachable to the naked trimmer head of the weed trimmer with the enclosure fasteners, and the replacement cutting implement is configured to be attachable to a rotatable axle of the naked trimmer head, such that the cutting enclosure is configured to cover the rotatable replacement cutting implement, above and to sides of the cutting implement, such that the cutting enclosure in combination with a rotation of the replacement cutting implement is configured to create a substantially planar air vortex that propels cuttings, which are contained and directed by the cutting enclosure, and wherein the cuttings are ejected through the ejection aperture, wherein the cutting implement and the protruding spacer are configured to be mounted on the rotatable axle and tightened in place with the cutting implement fastener, such that the protruding spacer protrudes underneath the cutting implement, whereby the protruding spacer reduces a risk of close contact with the ground, whereby strength of the air vortex is reduced, and a risk of the cutting implement impacting ground during use is reduced.

11. The weed trimmer extension system of claim 10, wherein the replacement cutting implement further comprises a cutting blade, and at least one perpendicular fin, which is perpendicularly connected to the cutting blade, along a length of the cutting blade.
