Abstract

An accessory system configured to be coupled to an exercise machine that enables the exercise machine to be used for other exercises. In some embodiments, a rowing accessory system may be operatively coupled to an exercise machine to enable the user to perform rowing exercises and the like. In some embodiments, a support accessory system may be operatively coupled to an exercise machine to enable the user to perform exercises with the exercise machine in an inclined use configuration, a rocking use configuration, or an inclined-and-rocking use configuration.

First claim

What is claimed is:

1 . A rowing accessory system configured to be coupled to an exercise machine, the rowing accessory system comprising:
a front support configured to support a front end of the exercise machine above a support surface; a rear support configured to support a rear end of the exercise machine above the support surface, the rear support including a strut having a lower end configured to be positioned proximate the support surface and extending upwardly to an upper end; a secondary carriage support including an intermediate support disposed between the front support and the rear support, the secondary carriage support including at least one secondary rail extending between the intermediate support and the rear support and suspended above the support surface; a secondary carriage operatively coupled to the at least one secondary rail and configured to be slidably moveable along the at least one secondary rail; at least one biasing member operatively coupled between the secondary carriage and the front support, the at least one biasing member configured to provide a biasing force on the secondary carriage that biases the secondary carriage toward the front support; a user interface positioned proximate the upper end of the strut; and a force transfer assembly operatively coupled between the user interface and the secondary carriage such that an exercising force applied to the user interface exerts a pulling force on the secondary carriage that tends to move the secondary carriage along the at least one secondary rail toward the rear support in opposition to the biasing force of the at least one biasing member.

2 . The rowing accessory system of claim 1 , wherein the force transfer assembly comprises a cable and pulley assembly.

3 . The rowing accessory system of claim 1 , wherein the force transfer assembly comprises:
a cable and pulley assembly including a cable having a first end attached to the rear support and extending to a first pulley coupled to the secondary carriage, the cable operatively engaging the first pulley and extending back from the first pulley to a second pulley attached to the rear support proximate the lower end of the strut, the cable operatively engaging the second pulley and extending upwardly from the second pulley to operatively engage a third pulley attached proximate the upper end of the strut, and wherein the user interface is operatively coupled to a second end of the cable proximate the third pulley.

4 . The rowing accessory system of claim 1 , wherein the secondary carriage includes a carriage body having at least one guide member configured to slidably engage the at least one secondary rail.

5 . The rowing accessory system of claim 1 , wherein the secondary carriage includes a carriage body having at least one roller configured to rollably engage a lower portion of the exercise machine during movement of the secondary carriage on the at least one secondary rail.

6 . The rowing accessory system of claim 1 , wherein the secondary carriage is configured to be slidably moveable along the at least one secondary rail in a rearward direction toward the rear support when the pulling force is greater than the biasing force of the at least one biasing member, and is configured to be slidably moveable along the at least one secondary rail in a forward direction toward the front support when the biasing force of the at least one biasing member is greater than the pulling force.

7 . The rowing accessory system of claim 1 , wherein the at least one secondary rail comprises two secondary rails laterally spaced apart on opposing sides of a centerline of the accessory system.

8 . A rowing accessory system configured to be coupled to an exercise machine having a rail and a slidable carriage operatively coupled to the rail, the rowing accessory system comprising:
a front support configured to support the exercise machine proximate a front end and to support the rail above a support surface; a rear support configured to support the exercise machine proximate a rear end and to support the rail above the support surface, the rear support including a strut having a lower end configured to be positioned below the rail and extending upwardly to an upper end configured to be positioned above the rail; a secondary carriage support including an intermediate support disposed between the front support and the rear support, the secondary carriage support including at least one secondary rail extending between the intermediate support and the rear support and suspended above the support surface; a secondary carriage operatively coupled to the at least one secondary rail and configured to be slidably moveable along the at least one secondary rail and configured to be disposed between the rail of the exercise machine and the support surface; at least one biasing member operatively coupled between the secondary carriage and the front support, the at least one biasing member configured to provide a biasing force on the secondary carriage that biases the secondary carriage toward the front support; a user interface positioned proximate the upper end of the strut; and a force transfer assembly operatively coupled between the user interface and the secondary carriage such that an exercising force applied to the user interface exerts a pulling force on the secondary carriage that tends to move the secondary carriage along the at least one secondary rail toward the rear support in opposition to the biasing force of the at least one biasing member.

9 . The rowing accessory system of claim 8 , wherein the force transfer assembly comprises a cable and pulley assembly including a cable having a first end attached to the rear support and extending to a first pulley coupled to the secondary carriage, the cable operatively engaging the first pulley and extending back from the first pulley to a second pulley attached to the rear support proximate the lower end of the strut, the cable operatively engaging the second pulley and extending upwardly from the second pulley to operatively engage a third pulley attached proximate the upper end of the strut, the user interface being operatively coupled to a second end of the cable proximate the third pulley.

10 . The rowing accessory system of claim 8 , wherein the secondary carriage includes a carriage body having at least one guide member configured to slidably engage the at least one secondary rail during movement of the secondary carriage on the at least one secondary rail.

11 . The rowing accessory system of claim 8 , wherein the secondary carriage includes a carriage body having at least one roller configured to rollably engage the rail of the exercise machine during movement of the secondary carriage on the at least one secondary rail.

12 . The rowing accessory system of claim 8 , wherein the secondary carriage is configured to be slidably moveable along the at least one secondary rail in a rearward direction toward the rear support when the pulling force is greater than the biasing force of the at least one biasing member, and is configured to be slidably moveable along the at least one secondary rail in a forward direction toward the front support when the biasing force of the at least one biasing member is greater than the pulling force.

13 . The rowing accessory system of claim 8 , wherein the at least one secondary rail comprises two secondary rails laterally spaced apart on opposing sides of a centerline of the accessory system, and wherein the secondary carriage includes a carriage body having a pair of guide members, each guide member being configured to slidably engage one o
