Exercise device
First Claim
1. An exercise device having, in combination:
- an elongated, two-piece base platform adapted to be placed on a flat supporting surface and comprising two elongated, generally rectangular and substantially similar box-like platform sections each having a closed upper side and narrow sidewalls and end walls having edges for engaging the supporting surface, said sidewalls and end walls defining an open lower side of each platform section;
said platform sections being positionable in end-to-end relation to form an elongated base platform and being positionable with said edges together in a closed position for transporting and storing the exercise device;
releasable base connectors for joining said platform sections together in end-to-end relation comprising U-shaped connecting pins, said base sections having two sets of holes for receiving ends of the base connectors with the latter straddling the adjacent end walls of the base sections;
two rotary disk assemblies each having an upper disk element sized to support a user'"'"'s foot, or hand, a lower disk element mountable on one of the platform sections, and a bearing between said elements rotatably supporting the upper disk element on the lower disk element;
each of said platform sections having a longitudinal series of spaced mounting holes in the central portion of the upper side thereof and each of said lower disk elements having a lower side and a depending mounting pin on the lower side engageable in a selected one of said mounting holes to position the disk assembly on the platform section;
and selectively engageable and releasable latches on said platform sections for holding them releasably in the closed position, and a carrying handle on one of said sidewalls, said disk assemblies being sized to fit within the exercise device in said closed position with said mounting pins reversely engaged in selected mounting holds in said upper sides.

Abstract
An exercise device comprising two box-like open-sided platform sections disposed side-by-side in a closed, storage and transporting position or end-to-end in an open exercising position and having two rotary disk assemblies that are mountable in a plurality of fixed exercising positions along the platform sections by means of pins on the lower sides of the disk assemblies and a longitudinal series of mounting holes in each platform section. Elongated elastic resistance bands are connectable between the rotary disks, on hook connectors thereon, and between the disks and the platform sections, in various ways for closed-chain operation, when desired, or removable for open-chain exercises. A carrying handle and latches are provided in the platform sections, and U-shaped connectors are provided to join the platform sections together.
