Patent number: 11624394Abstract: Provided herein is a fastener that may be used to secure objects to a channel strut or attach a channel strut to a structure. In an arrangement, the fastener is a fastener block configured for disposition within the interior of a channel strut. The fastener block has a body that includes at least one pair of spaced apart and parallel recesses (e.g., recessed channels) sized to engage the inward lips of the strut channel. Once the pair to recessed channels engage the strut channel lips, the fastener block is prevented from rotating. At least one aperture extends through the fastener block between the parallel recessed channels. A fastener recess (e.g., hexagon recess) is recede into the block around the aperture. A standard nut or bolt may be inserted into the fastener recess.Type: GrantFiled: October 22, 2020Date of Patent: April 11, 2023Assignee: D Three Enterprises, LLCInventors: Richard F.

Patent number: 10840851Abstract: The present disclosure is generally directed to mounting components on a corrugated metal roof. The disclosed systems and devices utilize a multi-surface clip (e.g., multi-planar) to securely attaching components such as rails to the corrugated metal roof while increasing the pullout strength of mounted structures and more evenly spreading the load of such mounted structures over the corrugated metal roof. In one embodiment, the multi-surface clip allows attaching a rail to the top of a rib of the corrugated metal roof while a fastener mechanically attaches the clip to a side surface of the rib. This allows the fastener to experience shear forces when upward forces (e.g., normal to the top surface of the rib) are applied to the rail or a structure supported by the rail.Type: GrantFiled: August 27, 2018Date of Patent: November 17, 2020Inventors: Richard F. Schaefer, David Kreutzman

Patent number: 10571135Abstract: Provided herein are various systems and methods (i.e., utilities) broadly directed to the generation of hot water using energy derived from renewable energy sources as an alternative to or in conjunction with another power source (e.g., fossil fuel-based energy from a utility provider, an underperforming solar/wind/wind system, etc.). In the various aspects, these utilities are directed to the retrofitting of existing water heaters with electrical heating elements that are connectable to a renewable source of electrical energy. While primarily discussed in relation to retrofitting existing water heaters, various aspects are applicable to OEM manufactured systems. Further, various control methods are provided that allow for enhancing the efficiency of hot water generation, net metering, and/or the generation of renewable energy credits.Type: GrantFiled: August 17, 2015Date of Patent: February 25, 2020Inventor: David Kreutzman

Publication number: 20190072296Abstract: Provided herein are systems and methods (i.e., utilities) that allow for the use of non-grid tied renewable energy systems (e.g., PV arrays and/or wind turbines) without requiring battery banks. In various aspects, these utilities permit the efficient use of renewable energy systems to generate electrical power as well as the ability to dynamically direct where such electrical power is applied.Type: ApplicationFiled: February 20, 2018Publication date: March 7, 2019Inventor: David Kreutzman

Publication number: 20180313578Abstract: Provided herein are systems and methods directed to using renewable energy sources with hot water heating systems. The system and method provide for interconnecting a single electrical heating element of a hot water heater to first and second electrical power sources. Typically, these first and second electrical power sources include a utility provided electrical power source (e.g., a fossil fuel AC power source) and a renewable energy power source. A controller selectively connects the first or second power sources.Type: ApplicationFiled: December 4, 2017Publication date: November 1, 2018Inventor: David Kreutzman

Publication number: 20180152133Abstract: The present disclosure is directed to a roof mounting system that utilizes a base plate that is affixed to a roof surface by multiple fasteners (e.g., lag bolts, screws etc.) and a cap (e.g., top cap) that attaches to the base plate covering the fasteners affixing the base plate to the roof surface. Once attached, the top cap covers the fasteners preventing water infiltration. To further waterproof the fasteners affixing the base plate to the roof surface, the base plate includes a raised or elevated section on its top surface with a planar flange extending around the elevated section. A portion of the flange may be disposed beneath a single or shingles on a roof surface. The fasteners extend through the elevated section. Accordingly, water drains around the elevated section when the base plate is attached to a roof surface further isolating the fasteners.Type: ApplicationFiled: June 7, 2017Publication date: May 31, 2018Applicant: D Three Enterprises LLCInventors: Richard F. Schaefer, David Kreutzman

Patent number: 9714671Abstract: A clamp is provided that allows for easily and securely mounting an object such as a PV panel to a rail having an internal recess or channel. The clamp utilizes one or more splice bars that extend into a recess of a rail that supports a PV panel. In one arrangement, the splice bar is inserted through an end of the rail into the recess such that a portion the splice bar extends beyond the end of the rail. A sliding clamp body engages lateral edges of the slice bar to, in one embodiment, compress a PV panel against a surface of the rail. The sliding clamp body may be affixed to the splice bar to secure the panel.Type: GrantFiled: September 21, 2016Date of Patent: July 25, 2017Inventors: Richard F. Schaefer, David Kreutzman
