  • Patent number: 6505844
    Abstract: A door transporting and support system for allowing an individual to easily transport and install a door within a doorjamb. The door transporting and support system includes a base having a door receiving channel, a pair of first arms extending from the base, a pair of second arms extending from the base, a plurality of caster wheels attached to the arms each by an adjustable threaded shaft, a plurality of support rods extending from the arms, and a plurality of support members removably attached to the support rods in a vertical manner. The base includes a pair of parallel side walls that define the channel. The height, angle and position of a door retained within the base are determined by the position of each threaded shaft of the caster wheels.

  • Patent number: 6234496
    Abstract: A transporting apparatus with directional braking is provided including a frame and a pair of wheel assemblies at least one of which includes a wheel with a plurality of teeth formed therein. Also included is a pawl assembly pivotally coupled with respect to the frame and having a pair of ends for engaging the teeth of the wheel when the pawl assembly is in a first orientation to allow only forward movement of the wheel of the wheel assembly. The pawl further serves to engage the teeth of the wheel when the pawl assembly is in a second orientation to allow only rearward movement of the wheel of the wheel assembly. Finally, the teeth of the wheel are disengaged when the pawl assembly is in an intermediate third orientation to allow both forward and rearward movement of the wheel of the wheel assembly.

  • Patent number: 6196586
    Abstract: A system is provided for leveling and stabilizing a forklift vehicle having a frame and at least one and preferably two axles pivotally connected with the frame. The system includes a frame leveler device including a hydraulic cylinder extending between the frame and the front axle and configured to move the frame with respect to the axle. A stabilizer device is mounted to the frame and includes a pair of arms and two stabilizer hydraulic cylinders. Each stabilizer cylinder has a piston with a rod connected with a separate one of the arms and a base chamber on one side of the piston. Further, a fluid exchange line extends between the base chambers of the two stabilizer cylinders and an exchange valve controls flow through the exchange line.

  • Patent number: 6183009
    Abstract: The invention relates to an inflatable gas bag (10) for an occupant restraint system of a vehicle, in particular of a motor vehicle. In order to avoid the formation of creases in the inflated state, which occurs with conventional gas bags and in order to be able to employ more lightweight textile materials for the manufacture of a gas bag, the gas bag (10) consists of a multilayered textile composite material which comprises at least one layer of a textile material and one layer of a polymer material whose melting range is lower than the melting range of the textile material. The textile composite material is formed into a specified three-dimensional shape which is to develop during inflation of the gas bag (10), and the individual layers of the textile composite material are joined together in this three-dimensional shape.

  • Patent number: 6182777
    Abstract: Existing track laying work machines fail to provide adequate suspension for reducing shock loads transmitted to machine components and the operator. The present suspension system provides suspension members interposed the main frame of the work machine and an elongated beam supported by first and second track roller frames. Cushioning members separate the roller frame from the elongated beam and drive wheel hub, to provide further isolation from shock and torsional movement of the roller frame.
