  • Patent number: 5931288
    Abstract: A cover for a channel, such as the channel which runs along the top of a section of conveyor track, is disclosed for excluding foreign matter from the interior of the track while allowing a pedestal extending from the interior of the track to traverse the channel. The cover is formed from two cover halves extending inwardly over the channel from supports running alongside of the channel, and the cover halves include resilient outer portions and hard yet flexible inner portions. The inner portions contact the passing pedestal and flex out of the way as the pedestal passes between them. The outer portions provide an inward biasing force against the inner portions for holding them against the passing pedestal and returning them to a closed position after a pedestal has passed.

  • Patent number: 5303655
    Abstract: An automatic stabilizing unit for a free trolley and a load carriage in an inverted power and free conveyor system is connected to the free trolley. The stabilizing unit includes a stabilizer actuator which extends above a free track containing the free trolley from beneath the floor of a building which houses the conveyor, and a stabilizing gear mounted on the load carriage. At locations in an assembly plant, such as robotic welders or riveting stations where load shifting tolerances are critical, there must be additional stabilization of the load carriage. At these locations, stabilizing rails are positioned on top of the free track in line with stabilizing trucks on the stabilizing actuator. When the stabilizing trucks contact the rails, the trucks are urged upward, pushing an attached piston upward against a spring which causes a pair of stabilizing wheels on the stabilizing gear to rotate downward into contact with the factory floor, thus stabilizing the carriage only when needed.

  • Patent number: 4893566
    Abstract: A golf cart system which can be installed on the fairway of a golf course. The cart system has improved power economy and anti-rolling and anti-pitching motions of the cart. The golf cart system includes a track embedded in the ground and a cart adapted to run on the track. According to the golf cart system, since the track exposed at the ground is very narrow, there is less chance of a golf ball hitting against the track. Even if a golf ball should happen to accidentally hit the exposed track portion, the ball will bounce similarly as when striking on natural grass if the exposed track portion is covered by elastic members such as artificial turf. This makes it possible to install the golf cart system on the fairway of a golf course. In addition, the rolling motion of the cart is effectively prevented by the first and second anti-rolling rollers.

  • Patent number: 4892041
    Abstract: A golf cart system which can be installed on the fairway of a golf course and which is excellent in power economy and anti-overturn effect. The golf cart system includes a track embedded in the ground and a cart running on the track. According to the golf cart system, since the track width exposed at the ground is very narrow, there is little chance of a golf ball hitting against the track. Even if a golf ball should happen to accidentally hit the exposed track portion, the ball will bound similarly as when striking on natural grass if the exposed track portion is covered by elastic members such as artificial turf. This makes it possible to install the golf cart system on the fairway of a golf course. In addition, since the anti-overturn rollers are so arranged that they elastically press onto the side walls of the track, the load acting between the driving wheels and the track is only the dead weight of the cart itself and therefore no excessive frictional force acts therebetween.
