Publication number: 20240035339Abstract: An improved adjustable hinge for a multi-position ladder that is positionable in a variety of configurations while being ergonomic to adjust and which is structurally sound, rigid, and easy to adjust, light in weight, and has a long service life. The mating surfaces of the outer hinge plates, inner hinge plates, and inner hinge center spacer are large, contributing to overall hinge rigidity and stability. The size of the lock button and lock bracket are each relatively large, making them ergonomic to operate, while also being large enough to be operable by a gloved human hand. A method of assembling an improved adjustable hinge for a multi-position ladder that is positionable in a variety of configurations.Type: ApplicationFiled: September 6, 2023Publication date: February 1, 2024Applicant: Tricam Industries, Inc.Inventors: Joseph P. Foley, Dennis D. Simpson, Benjamin P. Williams

Patent number: 11505994Abstract: An multi-position ladder is disclosed that includes an adjustable top cap that provides a tool or material tool tray when the ladder is in a stepladder position and provides a step when the ladder is in an extension ladder position is disclosed. The top cap generally comprises a rigid frame extending between the adjustable hinges of the multi-position ladder with a tool or utility tray and a step surface on opposing sides. The tool tray is parallel to the ladder rungs when the ladder is in a stepladder position, and the step surface provides a generally planar surface parallel the rungs when the ladder is in an extension position. The rigid frame of the top cap adds strength to the adjustment hinge and to the multi-position ladder. Embodiments allow for 12-inch hinge spacing, adding one foot reach in the extension position and six inch reach to the stepladder.Type: GrantFiled: October 16, 2019Date of Patent: November 22, 2022Assignee: Tricam Industries, Inc.Inventors: Joseph P. Foley, Benjamin P. Williams, Benjamin M. Wernberg, Dennis D. Simpson
