## Abstract

An item of exercise equipment with a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The exercise equipment may be a cycle mounted to a base. A roller and track arrangement may be provided between the cycle and base, to provide movement of the cycle in the axial direction and in a tilt direction relative to the base. The roller and track arrangement may be one or more curved roller and track engagement surfaces that extend in the axial direction and provide a gravity bias of the platform toward an axial neutral position. The cycle and base include a tilt biasing arrangement for biasing the cycle toward a tilt neutral position relative to the base.

## Claims

### Claim 1

An item of exercise equipment, comprising: a frame configured to support a user;
a user input arrangement movably mounted to the frame for enabling a user to apply input forces during exercise;
a support arrangement with which the frame is engaged and that supports the frame above a support surface, wherein the support arrangement is configured to provide movement of the frame in a fore-aft direction in response to input forces applied to the frame by the user, wherein the support arrangement is further configured to provide tilting movement of the frame about a tilt axis that extends primarily in the fore-aft direction;
a neutral biasing arrangement for biasing the frame toward a fore-aft neutral position and a tilting neutral position, wherein the neutral biasing arrangement comprises a first biasing arrangement for biasing the frame toward the fore-aft neutral position and a second biasing arrangement for biasing the frame toward a tilt neutral position;
wherein the frame is engaged with the support arrangement via engagement of a pair of rollers with a pair of support members, wherein the support members and rollers cooperate to provide fore-aft movement of the frame relative to the support arrangement, and
wherein the support arrangement includes a first pivot point at a proximal end of the support arrangement and a second pivot point at a distal end of the support arrangement, wherein the first pivot point is at a higher elevation than the second pivot point.

### Claim 2 (depends on 1)

The item of exercise equipment of claim 1, wherein the frame and the user input arrangement comprise a cycle-type device.

### Claim 3 (depends on 1)

The item of exercise equipment of claim 1, wherein the pair of support members are interconnected with the frame and the pair of rollers are interconnected with the support arrangement.

### Claim 4 (depends on 1)

The item of exercise equipment of claim 1, wherein relative axial fore-aft movement between the support members and the rollers results in movement of the frame in the fore-aft direction, and wherein pivoting movement of the support members on the rollers results in tilting movement of the frame about the tilt axis.

### Claim 5 (depends on 4)

The item of exercise equipment of claim 4 wherein the pair of support members comprises a front support member located toward a forward end defined by the frame and a rear support member located toward a rearward end defined by the frame, wherein the rear support member and the front support member define a tilt axis that is inclined in a rear-to-front direction.

### Claim 6 (depends on 1)

The item of exercise equipment of claim 1, wherein the first biasing arrangement comprises arcuate support members that provide a gravity bias of the frame toward the fore-aft neutral position.

### Claim 7 (depends on 1)

The item of exercise agreement of claim 1, wherein the support arrangement includes a base, and wherein the second biasing arrangement comprises a tilt neutral biasing arrangement interconnected between the base and the frame that applies opposite laterally directed biasing forces to the frame that urge the frame toward the tilt neutral position.

### Claim 8 (depends on 7)

The item of exercise equipment of claim 7 wherein the base includes a pair of laterally spaced apart stanchions, wherein the tilt neutral biasing arrangement comprises a centering guide member interconnected with the frame and located between the pair of stanchions, a pair of flexible elongated biasing members interconnected with and extending in laterally opposite directions from the centering guide member, and a biasing arrangement associated with each of the stanchions, wherein each flexible elongated biasing member is interconnected with one of the biasing arrangements, wherein biasing forces exerted by the biasing arrangements bias the centering guide member toward a neutral position corresponding to the tilt neutral position of the frame.

### Claim 9 (depends on 8)

The item of exercise equipment of claim 8, wherein the centering guide member defines an axially extending internal passage, and wherein the flexible elongated biasing members are interconnected with a shuttle that is movable within the internal passage of the centering guide member to accommodate fore-aft movement of the frame relative to the base.

### Claim 10 (depends on 8)

The item of exercise equipment of claim 8, wherein each biasing arrangement comprises one or more springs interconnected between one of the stanchions and one of the flexible elongated biasing members.

### Claim 11 (depends on 1)

The item of exercise equipment of claim 1, further comprising:
a support section arranged to support a front portion of the frame, wherein the support section is not integrally connected to a rear portion of the support arrangement and is configured to allow for bi-axial movement of the frame in response to input forces applied to the frame by the user.

### Claim 12

An exercise cycle, comprising:
a base configured for placement on a supporting surface;
a frame configured to support a user and including a pedal-type user force input arrangement;
a movable support arrangement interposed between the base and the frame for providing movement of the frame relative to the base during use, wherein the movable support arrangement is configured to provide axial fore-aft movement of the frame relative to the base and side-to-side tilting movement of the frame relative to the base, wherein the movable support arrangement includes a pair of axially spaced apart support members engaged with a pair of axially spaced apart rollers, wherein relative axial movement between the support members and the rollers permits axial fore-aft movement of the frame relative to the base about front and rear tilt supports, and;
an axial centering arrangement interposed between the base and the frame for biasing the frame toward an axial fore-aft neutral position; and
a tilt centering arrangement interposed between the base and the frame for biasing the frame toward a tilt neutral position, wherein the front tilt support is at a higher elevation relative to the rear tilt support.

### Claim 13 (depends on 12)

The exercise cycle of claim 12, wherein relative pivoting movement between the support members and the rollers permits side-to-side tilting movement of the frame relative to the base.

### Claim 14 (depends on 13)

The exercise cycle of claim 13, wherein each support member has an arcuate configuration that provides a gravity bias of the frame relative to the base in the axial fore-aft direction.

### Claim 15 (depends on 12)

The exercise cycle of claim 12, wherein the tilt centering arrangement is configured to apply oppositely directed lateral forces on the frame at a location below a tilt axis defined by the front and rear tilt supports that tend to urge the frame toward the tilt neutral position.

### Claim 16 (depends on 12)

The exercise cycle of claim 12, further comprising:
a support section arranged to support a front portion of the frame, wherein the support section is not integrally connected to a rear portion of the moveable support arrangement and is configured to allow for bi-axial movement of the frame in response to input forces applied to the frame by the user.
