Resistance system for fitness equipment
First Claim
1. A resistance system for fitness equipment, comprising:
- a frame;
plural resistance blocks;
plural resistance devices coupled to the plural resistance blocks;
an engagement mechanism including a plurality of support disks on a common shaft rotatably mounted for selective direct engagement with specific resistance blocks of the plural resistance blocks;
a carriage coupled to the plural resistance devices and moveable relative to the frame;
a recoil bar adapted to support resistance blocks not engaged with the engagement mechanism when the carriage is displaced from a resting position; and
a user interface member coupled to the carriage, whereby movement of the carriage is resisted by resistance devices that are selectively and non-sequentially engaged by the engagement mechanism.

Abstract
A resistance system for fitness equipment includes a frame, a resistance source such as an elastic cord, coil or any other type of spring, weight, pneumatic or hydraulic cylinders. The resistance source is mounted to a resistance block with a load support. A support disk is provided that is movably mounted to the frame and adapted to enable selective engagement with the load support. A transmission member, including a pliable member such as a cable, belt or other member, is coupled to the resistance source. Movement of the support disk enables selective engagement of the resistance source. In this way one or more individual resistance sources can be selectively engaged or disengaged to vary the resistance to the user by actuation of a dial or other actuator as directed by the user.

27. A method of providing resistance for an exercise device of the type including a frame, plural resistance devices, plural resistance blocks coupled to the resistance devices, an engagement mechanism including a plurality of support disks on a common shaft rotatably mounted for selective direct engagement with specific resistance blocks, a carriage coupled to the plural resistance devices and moveable with respect to the frame, the carriage including a user interface and a recoil bar adapted to support resistance blocks not engaged with the engagement mechanism when the carriage is displaced from a resting position, the method including the steps of:
-
moving the engagement mechanism to engage selected resistance blocks; actuating the carriage with respect to the frame so as to displace a portion of the resistance source, thereby applying a resistance to movement of the carriage at the user interface.

28. A resistance system, comprising:
-
an engagement mechanism including a plurality of support disks on a common shaft rotatably coupled to a frame; plural resistance blocks with a center recess adapted to receive a portion of the engagement mechanism for selective direct engagement with specific resistance blocks of the plural resistance blocks; plural resistance devices coupled to the plural resistance blocks; a carriage coupled to the plural resistance blocks and movable with respect to the frame, the carriage including a user interface; and a recoil bar adapted to support the resistance blocks not engaged with, and while displaced from the engagement mechanism.
