The pressure chamber contains a trapped volume of gas under pressure for supporting the load on a wheel or axle, the working chamber contains a volume of liquid under pressure which is trapped between the first diaphragm, and oppositely acting one-way valves or restrictors are provided for damping liquid flow in the working chamber. The side of the second diaphragm remote from the working chamber is subjected to a supply of liquid of which the pressure can be altered to compensate for changes in pressure in the pressure chamber due to changes in the loading on a vehicle.

Abstract: A bumper assembly for a vehicle comprises a center section adapted to lie along the width of the vehicle and two side sections connected to respective ends of the center section and adapted to lie along respective sides of the vehicle. Each section has a supporting metal beam and a superposed polyurethane moulding. The center section additionally has a superposed decorative steel finisher connected to the beam in a relatively displaceable manner. The side sections are connected at their ends remote from the center section by spring pivotal radius arms to the vehicle body. In the event of an impact, the side sections pivot away from the vehicle body on their radius arms against the action of the associated springs and the metal beam moves relative to the finisher against the action of a further spring. On removal of the impact force the parts of the assemby return to their original positions under the action of the various springs.

Abstract: A camper cover for mounting over the cargo area of a vehicle, such as a pick-up truck. The camper cover includes a plurality of frame members adapted for mounting on the pick-up truck to support a flexible cover over the cargo area of the vehicle. A flexible cover preferably of canvas or plastic carries a fastener for fastening the cover over the frame members and to the vehicle. The fastener includes a hook and loop type separable fastener having a first part carried by the flexible cover and a complementary part carried by the vehicle for releasable interengagement with said first member. The first part of the fastener secured to the canvas is located in a position to maintain the canvas in a taut disposition when in interengagement with the complementary part. Another embodiment includes the use of a flexible cover over the cargo area of the vehicle secured to the vehicle by use of a fastener including a hook and loop type separable fastener without the employment of frame members.

Abstract: The present invention relates to an elevator device, preferably an elevator by a building facade and comprising a trolley which is displaceable along a track provided on a foundation, by way of example a roof, a lifting element as a lift cage, supported by the trolley means and a hoisting machinery provided for the vertical displacement of the lifting element. According to the invention the track is formed by a number of separate support elements arranged in rows preferably two rows.

Abstract: This energy absorbing bumper mount comprises a spring bracket assembly which includes a pair of diverging spring arms that carry pins on the outer end thereof. A preloaded yieldable energy absorbing band of oriented plastic material is stretched across the arms by attachment to the pins. On impact of a bumper attached to the spring arms, the pins are laterally displaced from one another as the spring arms are deflected. Energy is absorbed by the stretching of the band and by deflection of the spring arms. Rebound is controlled with the slow recovery rate of the band acting as a buckling column to retard recovery of the spring arms to their normal undeflected position.

Abstract: A trailer suspension of the type including a leaf spring pivotally connected at its opposite ends to the trailer frame and supported at its midpoint by the wheel axle has a special saddle assembly for securing the axle to the spring.
