Abstract: A scaffold device for harvesting and maintaining fruit trees is disclosed comprising a frame structure adapted for securement to a movable support means such as a conventional pick-up truck, a generally semi-circular open ended catwalk attached to the frame structure and residing in an elevated horizontal plane, and an upstanding ladder attached to the catwalk and extending upwardly therefrom and inclined toward the center of the semi-circle.

Abstract: A fold-up ladder is provided for a combine which pivotally connects at its upper end to a deck adjacent an operator's cab at the forward end of the combine. The axis of the pivot connection at the upper end of the ladder substantially coincides with the edge of the deck and the edge of the upper step of the ladder. A gas spring is connected between the deck and the ladder to counterbalance the weight of the ladder as it swings from its lowered position to its overhead transport position. The gas spring has a desirable stabilizing influence on the ladder as it is raised and lowered. When the ladder is moved from its transport position to a lowered position, the line of force of the gas spring passes "overcenter" in relation to the ladder pivot axis thereby permitting the gas spring to releasably hold the ladder in its down position. Appropriate abutments are provided to properly position the ladder in its desired transport and lowered positions.

Abstract: A tree platform supported between two tree branches made up of a platform-like member having ends suitable to slide down between two diverging tree branches, two legs are hinged to the underside of the platform member and a turnbuckle engages the lower ends of the legs forcing them out into engagement with the tree branches thereby holding the platform in place. The turnbuckle ends are generally elliptical in shape and have outer peripheral grooves which receive the loops of two ropes that dangle from the turnbuckle and ladder steps are supported on the two ropes providing a ladder for a person to climb into place on the platform. The ladder will also provide a rope for a hunter to drag a deer.

Abstract: A rigid guide assembly having two inwardly disposed facing channel members secured to the stringer of a stationary platform and one end of a support member attached at each outward side of the top portion of the channel member. The other end of each support member is secured to the decking of the stationary platform. A vertical ladder secured to a floating base is disposed between the flanges of the two channel members thereby restricting the lateral movement of the ladder and float while allowing vertical movement as the water level changes.

Abstract: A platform structure adapted for rapid assembly and a method of assembling the platform structure. A plurality of prefabricated column assemblies are removably anchored on a platform foundation, and prefabricated landing assembly means are removably mounted with the column assemblies to form a landing above the platform foundation. Subsequently, a stair assembly is removably mounted between the landing assembly means and the platform foundation to provide a passageway permitting ingress and egress to the landing.

Abstract: A bus boarder for a wheelchair and its occupant and for the ambulatory impeded, embodies an elevator platform which is mounted within the entrance area at the front of the bus. The floor and the steps at the entrance are removed and a U-shaped reinforcing frame forms a well for the elevator platform. The elevator platform and its operating mechanism are so constructed that the doors open against each side of the entrance opening as originally provided for the bus. The elevator platform is lowerable to the ground or curbstone with the steps folded into a ramp for the wheelchair which is moved thereon by its occupant or an attendant and onto the platform. A fare box is mounted on a pivoted arm which is rotatable horizontally into a well in the bus dashboard, so as not to impede either the vertical motion of the elevator platform, or the maneuvering of the wheelchair thereon. The wheelchair occupant enters the platform backwards if the chair is of extended size, or if of standard size either forward or backward.

Abstract: A step stool includes a handrail attached to one side with non-skid steps that make it safe when standing on the step stool. Stabilizing bars are connected to the step stool to prevent it from tipping over due to a user placing his weight on the hand rail when standing on the step stool.

Abstract: A collapsible platform adapted to be erected in shallow water for surf fishing. Bearing plates connected to the lower ends of extensible legs stabilize a support panel to which a folding chair is hingedly connected. The platform is anchored in place by a handle operated actuating rod connected to a screw element adapted to penetrate the supporting sand formation below the water surface.
