Abstract
An implement handle includes an axially elongated core member having a varying cross-sectional outer dimension, and an outer polymeric shell having axially-oriented substantially-continuous strength members, the outer shell enclosing and being bonded to the core and of substantially uniform thickness. The handle may include a wood core and a bendable portion integral with the shell, the bendable portion being adapted to fit within a handle socket of a tool.
Claims16
An implement handle, comprising:
- an axially elongated polymeric shell having an axial centerline and a closed and hollow cross-sectional shape of predetermined inner and outer dimensions wherein both the inner and outer dimensions vary along the axial length of the shell, said dimensional variation including several dimensional reversals comprising positive and negative changes in the inner and outer dimensions with respect to the axial centerline, whereby a complex tapered shape is formed;
- substantially-continuous axially-oriented reinforcing fibers embedded in the shell;
- and
- a core member fully enclosed within said shell, the core member having outer dimensions which conform to the inner dimensions of said shell.
