Abstract

A knitting needle with a flexible cord, comprising: a bamboo or wood needle body having a tapered rear end section which includes a joint face and a conical peripheral surface and has an axial bore formed therein; a headed reinforcing member having an enlarged head formed at a rear end of a shank which is fastened to the bore of the rear end section and has an axial mounting bore extending thereinto through the head which includes a conical peripheral surface, a forward joint face and a rearward joint face; and a flexible cord having an enlargement which includes a forward joint face, a conical peripheral surface and an axial extension extending forwardly from the enlargement into the bore of the reinforcing member, wherein the peripheral surface of the reinforcing member is interposed between and flush with the peripheral surface of the rear end section and the peripheral surface of the enlargement, with the rearward joint face of the rear end section bonded to the forward joint face of the reinforcing member and with the forward joint face of the enlargement bonded to the rearward joint face of the reinforcing member.

Claims

1. A knitting needle with a flexible cord, comprising

at least one rigid needle body made of bamboo and having a tapered rear end section which includes a rearward joint face and a substantially conical peripheral surface and has an axial bore formed therein,

a headed reinforcing member having a cylindrical shank inserted into and fastened to said axial bore of said rear end section,

said headed reinforcing member further having an enlarged head formed at a rear end of said shank and an axial mounting bore extending through said enlarged head into said shank,

a flexible cord formed of a synthetic resin and having an enlargement which includes a forward joint face, a substantially conical peripheral surface, and an axial extension extending forwardly from said enlargement into said axial mounting bore of said reinforcing member,

said enlarged head including a substantially conical peripheral surface, a forward joint face and a rearward joint face,

said conical peripheral surface of said enlarged head being interposed between and substantially flush with said conical peripheral surface of said rear end section and said conical peripheral surface of said enlargement,

said rearward joint face of said rear end section being bonded to said forward joint face of said enlarged head, and

said forward joint face of said enlargement being bonded to said rearward joint face of said enlarged head.

2. The knitting needle as defined in claim 1, wherein said rearward joint face of said enlarged head and said forward joint face of said enlargement are substantially conical.

3. The knitting needle as defined in claim 1, wherein

said rearward joint face of said enlarged head and said forward joint face of said enlargement are annular.

4. The knitting needle as defined in claim 1, wherein

said headed reinforcing member is formed with an air-outlet passage means.

5. The knitting needle as defined in claim 1, wherein

said headed reinforcing member and said rear end section are formed by shaping blanks thereof together to provide a flush relation between said conical peripheral surface of said rear end section and said conical peripheral surface of said enlarged head after said headed reinforcing member has been bonded to the said rear end section.

6. The knitting needle as defined in claim 1, wherein

said headed reinforcing member is formed of a solid headed blank, and

said axial mounting bore of said headed reinforcing member is formed by drilling in said blank after said blank has been bonded to said rear end section.

7. The knitting needle as defined in claim 1, wherein

said headed reinforcing member is formed of a pre-bored blank having said axial mounting bore of said headed reinforcing member.
