Trimmer head with members for simplifying the loading of the cutting line

Abstract

The trimmer head (1) includes: an axis of rotation (A-A); a housing (3); a spool (13) insertable in the housing, configured and arranged to wind a stock of cutting line (F) therearound. The spool includes flanges (13A, 13B), between which anchoring elements (15) extend to anchor the cutting line.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of gardening products. More in particular, the invention relates to improvements to trimmer heads for brush cutters or the like, using a line made for example of plastic as a vegetation cutting member.BACKGROUND ART[0002]In the field of gardening equipment for use at both amateur and professional level, the use is well known of trimmer heads applied at the end of a drive shaft of a brush cutter or other equipment, to cut vegetation. Some trimmer heads of this type use a line made of synthetic resin, typically polyamide, to cut the vegetation. Usually, the line is wound inside the trimmer head to form a stock and exits from one or more holes provided in a housing of the trimmer head, inside which a spool is usually provided forming a stock of cutting line. During use, the cutting line wears and breaks. Therefore, a length of the cutting line projecting through the passage holes of the housing shall be periodically replac...

AI Technical Summary

Benefits of technology

The invention relates to a trimmer head with a spool for winding cutting line. The spool has a flange with a cutting line anchoring element that allows the cutting line to be easily and quickly anchored to the spool without the need for opening the housing. The line can be quickly replaced without positioning the spool angularly with respect to the outer housing. The trimmer head also has guides to facilitate the insertion of the cutting line in the passage holes. The technical effects of the invention are improved ease of use, efficiency, and flexibility.

Problems solved by technology

During use, the cutting line wears and breaks.

This operation is long and complex.

These systems, even if more practical than those requiring to open the housing to replace the cutting line, have some drawbacks due to the difficulty in passing the cutting line through the spool hole.
