Patent number: 11993908Abstract: A cover for an underground enclosure may include an upper surface comprising a pattern of bosses, a first slot and a second slot disposed on the upper surface, a lower surface opposite the upper surface. A first reinforcement member may be coupled to the lower surface. The first slot may extend into the first reinforcement member, and a second reinforcement member may be coupled to the lower surface and aligned with the first reinforcement member. The second slot may extend into the second reinforcement member. The cover may be configured to be lifted by the first slot and the second slot.Type: GrantFiled: October 11, 2022Date of Patent: May 28, 2024Assignee: Hubbell IncorporatedInventors: Hsi Jen Wang, Cauley Sean Price, Jerry Dale Goolsby, Lemuel David Fagan

Publication number: 20240125079Abstract: Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.Type: ApplicationFiled: December 20, 2023Publication date: April 18, 2024Inventors: Lemuel David Fagan, Keith Alden Chudley, Ernest Stephen Forsten, Jason David Estes

Patent number: 11466423Abstract: A cover for an underground enclosure may include an upper surface and may include a pattern of bosses, and a first slot and a second slot each disposed on the upper surface. The cover may also include a lower surface opposite the upper surface. A first rib or reinforcement member may be coupled to the lower surface. The first slot may extend into the first rib or reinforcement member. A second rib or reinforcement member may be coupled to the lower surface and aligned with the first rib or reinforcement member. The second slot may extend into the second rib or reinforcement member. The cover may be configured to be lifted by the first slot and the second slot.Type: GrantFiled: May 28, 2020Date of Patent: October 11, 2022Assignee: Hubbell IncorporatedInventors: Hsi Jen Wang, Cauley Sean Price, Jerry Dale Goolsby, Lemuel David Fagan

The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers and forms the bulk of the cover. The polymer matrix bonds the reinforcement layers so that forces applied across the top and bottom layers are communicated to the edge reinforcement layer. The polymer matrix includes a thermoset polymer resin and an expanded glass bead filler.Type: ApplicationFiled: June 14, 2021Publication date: September 30, 2021Inventors: Keith Alden Chudley, Lemuel David Fagan, Jason David Estes, Jeffrey Douglas Angelo
