Abstract

A weight training machine comprises: a motor; a line that is tensioned by the motor; a spool that takes up the line, wherein the spool includes a flange wherein the flange defines a capture region for the line; and a line guide adjacent to the spool, wherein the line guide prevents the line from persistently escaping from the capture region for the line.

Claims (13)

1 . A weight training machine, comprising:

a motor;

a line that is tensioned by the motor;

a spool that takes up the line, wherein the spool includes a flange wherein the flange defines a capture region for the line; and

a line guide adjacent to the spool, wherein the line guide prevents the line from persistently escaping from the capture region for the line, and wherein the line guide comprises an axially-angled surface to funnel the line back to the capture region after an escape departure of the line.

2 . The weight training machine of claim 1 , wherein the line guide directs the line axially.

3 . The weight training machine of claim 1 , wherein the line guide is part of a duct.

4 . The weight training machine of claim 1 , wherein the line guide is positioned parallel to the flange.

5 . The weight training machine of claim 1 , wherein the line guide and the flange define a gap smaller than a diameter of the line.

6 . The weight training machine of claim 1 , wherein the line and/or spool is coated with an adhesive to adhere the line to the spool.

7 . The weight training machine of claim 1 , wherein the spool comprises a grooved surface that allows the line to come off tangentially from the spool easier than it allows the line to come off radially from the spool.

8 . The weight training machine of claim 1 , wherein an axis of the spool is oriented horizontally.

9 . The weight training machine of claim 1 , wherein an axis of the spool is oriented at an angle between vertical orientation and horizontal orientation.
