Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
Corner connector for non-metal parts of furniture, comprising: a rotary eccentric worm formed as a sleeve member and a binding bolt having a head, said sleeve member including a slit at one end of said sleeve member, a pair of oblique surface portions for receiving said head, arranged along a gap cutout on an inner side of said sleeve member substantially perpendicular to said slit, another cutout facing said gap cutout, extending circumferentially and substantially perpendicular to said slit, said another cutout terminating at another end of said sleeve member, and wherein a bottom of said oblique surface portions begins at a mouth of said gap cutout substantially on a mantle surface of said sleeve member and ends at a semicircular termination of said cutout, substantially on an inner surface of said sleeve member.
