EXERCISE MACHINE WITH MOVABLE USER SUPPORT

摘要

An exercise machine with a two directional pivoting user support assembly has a user support or platform which supports the user and pivots about a first pivot axis during an exercise movement, and is also pivotable about at least one second pivot axis to involve the user's core muscles in balancing and maintaining the user support in a stable position. A manually operable locking device with a simple flip switch lever is provided for selectively locking the user support against rotation about the second pivot axis, so that the user can easily chose whether to perform the exercise with a stable support or to add a level of difficulty by using the unstable seat mode and exercising core muscles during the exercise.

主权项

1. A movable user support assembly for supporting a user in a seated or kneeling position while performing an exercise on an exercise machine, comprising:
a base; a two directional pivoting user support associated with the base and configured to support a user in an exercise position while performing an exercise, the user support being rotatable about a first pivot axis during the exercise; a pivotal connection between the base and the user support defining at least one second pivot axis for free rotational movement of the user support about said at least one second pivot axis in at least two opposite directions between first and second end positions, the user support having a centered support position between said end positions; and a locking device which is configured to selectively lock the user support against rotation about the second pivot axis, the locking device having a first, locking position defining a stable support mode in which the user support rotates about the first pivot axis only and is locked against rotation about the second pivot axis, and a second, released position defining an unstable support mode in which the user support is free to rotate about said second pivot axis between said end positions.
