Abstract: A workstand for use when servicing heavy tracks or the like, the workstand including opposing curved first and second sides spaced apart from each other and a top support platform extending therebetween. Upper and lower steps extend between the front portions of the curved first and second sides to provide access to the top support platform. The curved first and second sides combine with the top support platform and the steps form a structure having a wheel receiving area therein and having an open backside that provides access to the wheel receiving area. The workstand is constructed to be positioned around a tire of the truck's wheel assembly with the first and second sides immediately adjacent to the frame of the vehicle and the top support platform above the wheel receiving area so as to support a mechanic or the like above the wheel assembly adjacent to the vehicle's engine.

Abstract: A stepladder, which may be in the form of a usual stepladder/stool combination, is provided with safety outboard frame members desirably of inverted U-shape providing upwardly arched hand holds extending upwardly beyond the upper step of the stepladder sufficiently to obstruct lateral movement beyond the ends of such upper step of the legs of a person standing on such upper step. The stepladder/stool combination in particular is preferably provided with a latching arrangement limiting movement of the safety frame members from safety positions during use of the stepladder and for not permitting the stepladder to be placed into condition for use until such safety frame members are in safety positions.

Abstract: A portable hunting blind or observation and hunting stand, and wheeled carrier is provided. The unit is foldable and has lower, central and upper ladder elements interconnected by securable hinges. A wheel is located on the lower ladder element and a rotatable tree mounting element is disposed on the upper ladder element. The upper ladder element also has a seat platform and a separate standing platform located on the upper ladder element below the tree attaching element. The tree attaching element comprises a rotatable C-shaped portion with a nylon strap having a first end and a second end. The first end is secured to the C-shaped portion, the intermediate strap surrounds the tree trunk and the second end is placed in a ratchet style strap tightener which permits adjustment according to the circumference of the tree. The C-shaped portion is rotatable about two axes and legs may be inserted into this portion, the stand being free standing in tripod fashion. When folded the hunting blind becomes a carcass transporter, permitting one to easily wheel the kill to the game warden or vehicle.

Abstract: A ladder is disclosed including wheels normally received off the ground, and four legs normally supporting the ladder. When it is desired to move the ladder, it is pivoted off the legs until the wheels contact the ground and fully support the ladder. The ladder may then be moved. A rail includes an angled portion which provides a handle allowing the ladder to be easily moved. The wheel is most preferably mounted above the ground by a distance between its radius and its diameter such that when the ladder is supported on the wheels, the legs will not interfere with the ground.
