| 20090026018 | Self Erecting Zipper Lift - A zipper style lift that coils into a box for storage, but extends to form a rigid, self erecting lift part. The lift stores itself in a housing when retracted, by retracting chain parts into a spiral form. | 01-29-2009 |
| 20090308826 | Modular Winch for Stage Use - A winch formed of modular components can be reconfigured between different operational configurations. A number of different lengths and devices can be attached to the winch. | 12-17-2009 |
| 20090309080 | Turtle Winch for Stage Use - A “turtle” winch that rotates relative to a non-rotatable base. The rotatable part is held in place relative to the fixed base by v shaped grooves held in cam followers. | 12-17-2009 |
| 20090309081 | Zero Fleet Winch for Stage Use - A zero fleet winch with guides that move while a cable is wound on a drum. The guides hold the cable always at 90 degrees to the drum. A tensioning turnaround sheave keeps the cable tight. | 12-17-2009 |
| 20090309084 | Lineset Winch with Braking Parts - A winch which can operate with an external brake, or the external brake can be removed to operate with an internal brake. The winch has a cable drum that rotates to get cable on and off the drum. Two eccentric cams are rotated to always keep a soft plastic part pressed against the drum. | 12-17-2009 |
| 20090315006 | Tab Winch for Stage Use - A winch with adjustable arms allowing the length to be adjusted. The winch can have a very thin drum to allow it to fit in confined spaces. | 12-24-2009 |
| 20100005998 | Moving Trolley for an I Beam Extrusion - An I beam trolley that can move along an I beam | 01-14-2010 |
| 20100242562 | I-beam track with a Separate attachment portion - A dual sided extrusion, where one side has a different shape than the other side, and the extrusion is intended to be used in different orientations depending on the application. | 09-30-2010 |
| 20100247281 | Double Offset Caster System - A double offset caster system uses two sets of rotatable offsets relative to one another so that the caster can move relative to the load. The offset changes in order to change the relative offset between the caster position and the load. | 09-30-2010 |
| 20110079760 | Lineset Winch with Braking Parts - A winch which can operate with an external brake, or the external brake can be removed to operate with an internal brake. The winch has a cable drum that rotates to get cable on and off the drum. Two eccentric cams are rotated to always keep a soft plastic part pressed against the drum. | 04-07-2011 |
| 20110101292 | Reduced Size and Reconfigurable Winch - A zero fleet winch that has a hollow drum and a motor and gear assembly mounted inside the drum. A roller assembly moves with the rotation to keep constant the angle where the cable goes on and off the drum. | 05-05-2011 |
| 20110101293 | Workhorse Winch - A winch driven by a rotatable cassette. The cassette can be rotated into multiple different positions. Each of the addition positions produces a different speed up the output for a cable. | 05-05-2011 |
| 20110118038 | Universal Deck Track Dog with Replaceable Parts - A track dog with removable parts. Embodiments describe one or more of the following features. In one embodiment, the size of the receiver for the knife shaped piece can be variable. Another embodiment describes an improved technique of holding the cable that is run under the floor. Yet another embodiment describes a device where the cable attachment mechanism are set in a location that line up with the openings in the floor to allow tightening without opening the floor. Another aspect describes a special through hole so that cable can be run through the device, e.g., to connect to another track dog. | 05-19-2011 |
| 20110142591 | Truss Hinge - A truss hinge that includes a number of different labeled parts, where connections between the two different parts can constrain the truss to different angles. | 06-16-2011 |
