1. A device for supporting a line connected to a tool, comprising:
- an anchor structure adapted for fastening to an object;
a line retainer member fastened to said anchor structure, said line retainer member having a passageway through which the line is loosely fittable; and
a stop member associated with the line between said anchor structure and the tool, said stop member being larger than said passageway in said retainer member to thereby prevent movement of the line in one direction when said stop member is abutted against said line retainer member and thereby reduce pulling forces exerted by the line on the tool.

Abstract
A cord restraining device including a band fastened around the extremity of a user employing a corded, hand-held tool. Fastened to the band is a hook-member through which the cord is loosely suspended. Fastened to the cord is a stop member which, when abutted with the hook member, prevents further movement of the cord. In this manner, a desired length of cord can be suspended by the tool to thereby allow a user to more accurately balance the tool and prevent trauma and other disorders to joints such as the wrist, hand and fingers.

10. A device for supporting a cord connected to a tool, comprising:
-
a band engageable around an extremity of an operator utilizing the tool; a cord retainer attached to said band, said cord retainer having an opening for loosely supporting the cord; a stop member associated with the cord, said stop member being of a size larger than the opening in said cord retainer to prevent movement of the cord through the opening when said stop member is abutted with said cord retainer; and said stop member being constructed so as to be engageable with the cord such that a predefined length of the cord remains between the tool and said cord retainer irrespective of the location of the tool. - View Dependent Claims (11, 12, 13, 14)
