## Abstract

An adjustable exercise equipment system includes a post as part of an exercise machine; a trolley system for engagement with the post, the trolley system having a body forming a channel to receive the post; rollers supported by the body and to provide movement of the body along the post; and a receiver supported by the body, the receiver to engage with a user engageable device; the body and the of rollers allow for selective movement along the post as a user interacts with the user engageable device.

## Claims

### Claim 1

A trolley system for engagement with a post of a selected exercise machine, the trolley system comprising:
a body forming a channel, the channel to receive the post therethrough;
a plurality of rollers supported by the body and configured to provide movement of the body along the post;
a receiver supported by the body, the receiver configured to engage with a user engageable device; and
a locking system configured to lock the body at a position along the post, the locking system having a pin to extend through one or more apertures along the post and a clamp attached to the body and having one or more hooks to engage with the pin such that body is releasably locked to the pin;
wherein the body and the plurality of rollers selectively allow for movement along the post as a user interacts with the user engageable device.

### Claim 2 (depends on 1)

The trolley system of claim 1, wherein the plurality of rollers comprises:
a first plurality of rollers extending along a first portion of the body; and
a second plurality of rollers extending along a second portion of the body;
wherein the first plurality of rollers are configured to roll along a first surface of the post;
wherein the second plurality of rollers are configured to roll along a second surface of the post.

### Claim 3 (depends on 2)

The trolley system of claim 2, wherein the body further comprises:
a first side and a second side;
wherein the first plurality of rollers extend between the first side and the second side;
wherein the second plurality of rollers extend between the first side and the second side; and
wherein the channel is formed between the first side, the second side, the first plurality of rollers, and the second plurality of rollers.

### Claim 4 (depends on 1)

The trolley system of claim 1, further comprising:
a secondary attachment receiver extending from the body and having one or more ports to receive one or more secondary user engageable devices.

### Claim 5 (depends on 4)

The trolley system of claim 4, wherein the secondary attachment receiver further comprises:
one or more locking bolts rotatably engaged with the one or more ports to provide securement of the one or more secondary user engageable devices therein.

### Claim 6 (depends on 1)

The trolley system of claim 1, wherein the receiver further comprises:
a tubular opening to engage with a bar;
wherein the bar is a part of the user engageable device.

### Claim 7 (depends on 1)

The trolley system of claim 1, wherein the locking system further comprises:
a locking handle pivotally operable with the clamp such that the locking handle is configured to apply torque to the clamp to lock the clamp with the pin.

### Claim 8

An adjustable exercise equipment system, comprising:
a post;
a trolley system for engagement with the post, the trolley system having:
a body forming a channel to receive the post;
a plurality of rollers supported by the body and configured to provide movement of the body along the post;
a receiver supported by the body, the receiver configured to engage with a user engageable device;
a locking system configured to lock the body at a position along the post, the locking system having a pin to extend through one or more holes along the post and a clamp attached to the body and having one or more hooks to engage with the pin such that body is locked to the pin;
wherein the body and the plurality of rollers allow for selective movement along the post as a user interacts with the user engageable device.

### Claim 9 (depends on 8)

The system of claim 8, wherein the trolley system further comprising:
a secondary attachment receiver extending from the body and having one or more ports to receive one or more secondary user engageable devices.

### Claim 10 (depends on 9)

The system of claim 9, wherein the secondary attachment receiver further comprises:
one or more locking bolts rotatably engaged with the one or more ports to provide securement of the one or more secondary user engageable devices therein.

### Claim 11 (depends on 8)
