Abstract: Devices and methods are provided for cutting or forming tapered surfaces on the end portions of tube or pipe lengths prior to forming joints in adjoining lengths. A device body includes multiple guide surfaces, each having distinct size and shape to engage with an open end of a one of a multiple of tube of predetermined diameters. In intended use, a powered cutting device is rotated about the end of stationary tube or pipe.

Abstract: A vehicle enclosure includes a roof element that rotates upward from the occupant space to increase the passenger opening and increase ease of entry. The roof element is secured to and rotates about a horizontal vehicle frame element. The roof element also supports a windshield at the upper edge of the windshield during travel. The horizontal frame element is formed of a rigid tubular cross-section member including tubular hinge elements to which the roof element is secured to enable the rotating action of the roof element.

Abstract: A modular door assembly is adapted for installation on existing open frame vehicles formed of tubular members. A novel tubular hinge construction provides support for the door assembly while allowing rotational movement of the door in use. Alternative vehicle elements may also be secured to and operable on the novel hinge.

Abstract: A system of two door panels is defined with the panels arranged one above the other, each with independent horizontal movement operation. Each door panel is provided with a support and guide system that allows each to be moved horizontally into and away from an enclosure opening. The construction of the doors and supports enables attachment and operation on small lightweight vehicles in the nature of golf carts and similar vehicles. The construction details enable the panels to be secured onto to integrated into small light weight personal vehicles such as golf-carts and similar vehicles without substantially altering the vehicle's performance and operation.
