Abstract: An improved toy vehicle play set includes a base, a pillar or support, at least one platform, and a retaining mechanism. The pillar is configured to extend substantially vertically from the base. The at least one platform is coupled to the pillar and is configured to receive a toy vehicle. A retaining mechanism coupled to the at least one platform retains the toy vehicle on the platform until actuation of the retaining mechanism. Upon actuation, the retaining mechanism is reconfigured from a retaining configuration that retains the toy vehicle on the platform to a releasing configuration that enables the toy vehicle to roll off of the platform. Where multiple platforms are present, upon actuation, multiple retaining mechanisms are simultaneously reconfigured from a retaining configuration that retain toy vehicles on the multiple platforms to a releasing configuration that enables the toy vehicles to roll off of the platforms.

Abstract: A conversion kit for an enclosed trailer forms at least one animal stall in a storage compartment of the trailer. The conversion kit includes separable vertical stanchions and stall dividers which are removably mountable in the trailer storage compartment to form one or more stalls. A breastplate, a front wall and a feed tray may be mounted at a front end of the stall dividers. A manger door opens to a storage compartment below the feed tray. A saddle hanger may be mounted at a forward end of the front wall. Openable rear doors close one end of the stalls.

Abstract: An animal release chute for use in steer or calf roping competitions is described. The chute has a fixed section and a moveable section that telescopes forwardly relative to the fixed section. A release gate at the forward end of the moveable section is moveable between a closed position for retaining a steer or calf inside the chute and an open position releasing the steer or calf from the chute. A sensor at the rearward end of the fixed section senses the presence of the horse of the roper at the rearward end of the fixed section. Only when the roper's horse is at the rearward end of the fixed section can the gate be released to release the calf. The chute system assures that there is always the fixed, predetermined distance between the calf and the roper at release.

Abstract: A starting gate and timing device for foot races includes a frame and a plurality of levered restraints disposed across a track. Each of the levered restraints includes a barrier portion which is adapted to prevent a runner from crossing the start line before the barrier is moved out of the way. Each of the barrier portions also includes an audio speaker for alerting a runner of the start of a race. A scoreboard, timer and sensor are also provided for timing the race. A control system for controlling a start of a race is provided.

Abstract: A method for manufacturing a modular starting gate. The modules making up the starting gate include a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. Each module is manufactured to precise tolerances using fixtures or jigs to achieve the desired tolerances. The door releasing module is coupled to the truss module. The truss module is raised mounted to the towing module and the wheel assembly module. A first stall divider module is attached to the truss module and a positioning fixture is used to properly align a second stall divider module relative to the first stall divider module. The second stall divider module is attached to the truss module. The positioning fixture is removed and the front and back gate modules are fastened to the stall divider modules.

Abstract: A modular starting gate having a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. The door releasing module includes a roll-bar having articulated members that are coupled to the front door module via a coupling bar and a turnbuckle adjuster. The roll-bar is coupled to the truss module via a bearing and includes a first section coupled to a second section via a U-joint. A rebound stop is coupled to the starting gate, wherein the rebound stop has a first portion mounted to the front door module which cooperates with a second portion coupled to the stall divider module.

Abstract: A starter assembly which is used to provide a staggered running start for horses racing around an oval track comprises a base portion which mounts the assembly in a vehicle moving at the front of the race and a gating system comprising a central gate member which is located between a pair of corresponding gate arms. The central gate member is pivotally secured to the base portion for swinging the central gate member from a race starting position extending diagonally of the track, and after the race has started, to a ready to fold position perpendicular the track with the gate arms in line with the central gate member. The gate arms are then folded forwardly in a balanced manner at opposite ends of the central gate member.
