Abstract: A motorized, climbing tree stand ideal for hunting has a rigid elongated, track constructed from multiple, axially aligned sections attached to a tree trunk. A carriage supporting a seat and footrest is coupled to a shuttle assembly that engages the track. The shuttle assembly mounts a battery-powered motor and a motor-driven gear that engages a toothed rack on the elongated track, moving the carriage vertically upwardly or downwardly in response to motor operation. A hand switch controls a reversing relay to control motor direction. Each track section comprises a rigid, elongated flange with an elongated, tubular sleeve terminating in a reduced diameter coupling tube that coaxially mates with the base of the sleeve in the neighboring section. Alignment rods near the upper ends of each sleeve reinforce the assembly. Adjustable, L-brackets contact the tree for bracing. Track flanges are slidably constrained between suitable rollers secured to shuttle side walls.

Abstract: Modular elevator control housings having hinged faceplates that can be folded open to quickly expose the housing interior for service or modification. Each housing is generally in the form of a low profile, parallelepiped that is conveniently placed on a wall adjacent to an elevator car access position. The housing protectively encloses elevator operational controls, directional indicators, warning lights, or the like. The preferred housing comprises a chassis covered by a one-piece, folding faceplate interiorly hinged to the chassis that provides a display. The chassis comprises a subframe that secures the housing to the wall and a top and bottom cover. The subframe comprises a base bounded by integral, projecting side flanges that preferably terminate in upper lips. Extruded chassis sidewalls are secured to the subframe sides with fasteners captivated in part within captivating grooves defined in the sidewalls. Mounting grooves seat fasteners to secure the top and bottom covers to the sidewalls.
