## Abstract

An interactive exercise system includes a mechanical support system and a display module held by the mechanical support system. A force-controlled motor is attached to the mechanical support system and a reel is driven by the force-controlled motor. The interactive exercise system also has a handle graspable by a user and includes a cord extending between the reel and the handle. The handle or other accessory can be attached by a quick release mechanism. Force applied through the force-controlled motor is based at least in part on detected user force input.

## Claims

### Claim 1

An interactive exercise system comprising;
a mechanical support system;
a force-controlled motor attached to the mechanical support system;
a reel driven by the force-controlled motor having an attached cord; and
a detachable and user engageable component connected to the cord via a quick release mechanism, wherein force applied through the force-controlled motor is based at least in part on detected user force input;
wherein the quick release mechanism further comprises:
a first component attached to the cord;
a third component connected to the detachable and user engageable component;
a movable sleeve translatable away from the first component to release the third component from the quick release mechanism; and
a latch configured to hold the movable sleeve in place following translation away from the first component and configured to release the movable sleeve in response to insertion of the third component within the movable sleeve.

### Claim 2 (depends on 1)

The interactive exercise system of claim 1, wherein the quick release mechanism can be operated with one hand.

### Claim 3 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm having a multi-axis arm hinge assembly.

### Claim 4 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, and wherein the movable arm can be locked into place.

### Claim 5 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm supporting the detachable and user engageable component.

### Claim 6 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm supporting the detachable and user engageable component that is further able to be fixed in a stowed attachment with respect to the movable arm.

### Claim 7 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm having a magnetic strip and supporting a detachable and user engageable component that is further able to be magnetically fixed in a stowed attachment with respect to the movable arm.

### Claim 8 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm having a rotational arm mechanism for pivoting vertical arm rotation.

### Claim 9 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm having a manually controllable rotational arm mechanism for pivoting vertical arm rotation in response to activation of a vertically oriented button.

### Claim 10 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm having a manually controllable rotational arm mechanism for pivoting horizontal arm rotation in response to activation of a horizontally oriented button.

### Claim 11 (depends on 1)

The interactive exercise system of claim 1, wherein at least one movable arm is connected to the mechanical support system, with the movable arm being movable from a first folded position to an extended position.

a mechanical support system;
a cord attached to the mechanical support system; and
a detachable and user engageable component connected to the cord via a quick release mechanism that further comprises a first component attached to the cord, a movable sleeve supporting an attachment and release mechanism, and a third component having a pin connectable to the movable sleeve and being further connected to the detachable and user engageable component;
wherein the quick release mechanism further comprises:
a first component attached to the cord;
a third component connected to the detachable and user engageable component;

### Claim 20

A quick release comprising:
a first component;
a sleeve slidably mounted to the first component and defining an inner groove;
a first biasing member biasing the sleeve toward the first component and into a locked position;
a latch mounted to the first component and defining an outer groove;
a second biasing member biasing the latch away from the first component;
a first ball positioned between the latch and the sleeve; and
a second ball positioned within the sleeve and the first component and configured to engage a pin within the sleeve when the sleeve is in the locked position and to release the pin when the sleeve is urged away from the first component;
wherein the inner groove and outer groove are positioned that such that:
when the sleeve is urged away from the locked position, biasing of the latch away from the first component by the second biasing member urges the first ball into the inner groove such that the first ball resists movement of the sleeve toward the first component; and
when the pin pushes the latch toward the first component, the first ball moves into the outer groove and out of the inner groove thereby allowing the sleeve to be biased into the locked position by the first biasing member.
