Abstract
According to the invention there is provided a cord rewinder which includes two sets of multiple pulleys, each set being seated at an opposite end of an elongate housing. One set is fixed in place while the other set is biased toward its corresponding end of the housing. When a pull is applied to a cord helically wound around the pulleys and extending along the length of the housing between the pulleys, the biased pulley set moves toward the fixed pulley set releasing the cord. When the pull is removed, the biased pulley set moves back to its end position retracting the cord.

A rewinder for a cord of an armrest mounted telephone comprising:
- a housing adapted to be mounted to a telephone, the housing having a plurality of spring channels;
- a first set of pulleys fixedly engaged within the housing at one end thereof;
- a second set of pulleys movably engaged at an opposite end of the housing;
- and
- biasing means engaged to said second set of pulleys for biasing same away from said first set, the biasing means having a plurality of helical springs, each helical spring operatively engaging one of the spring channels of the housing;
- the sets of pulleys having a telephone cord wound therearound in a helical manner with turns of the cord each engaging a separate, opposite pulley.
In combination, an armrest mounted telephone assembly including an automobile telephone housing;
- an automobile telephone receiver removably mounted on the automobile telephone housing;
- a telephone cord rewinder apparatus mounted in side-by-side engaged relation to the automobile telephone housing;
- the rewinder apparatus having a rewinder housing mounted alongside of the automobile telephone housing, the rewinding housing having a plurality of spring channels;
- a first set of pulleys fixedly engaged within the rewinding housing at one end thereof;
- a second set of pulleys movably engaged at an opposite end of the rewinder housing;
- biasing means engaged to said second set of pulleys for biasing same away from said first set, the biasing means having a plurality of helical springs, each helical spring operatively engaging one of the spring channels of the rewinding housing;
- and
- a telephone cord wound around the sets of pulleys in a helical configuration with turns of the cord each engaging a separate, opposite pulley, the telephone cord being connected between the telephone receiver and the sets of pulleys in said receiver housing.
