    摘要: A method of twin-sheet vacuum forming plastic articles having the steps of clamping two parallel sheets of thermoplastic synthetic resin in a vertical orientation to a clamping tray and blowing air between the parallel sheets thereby creating a hollow cavity between the two parallel sheets. The two parallel sheets are then heated to molding temperature between two vertically oriented heaters. The two parallel sheets are disposed between opposing mold cavities of a vertically oriented split mold wherein the mold cavities have a contour conforming the configuration of the desired article. A negative pressure is applied to suction holes provided in the mold cavities which draw the two parallel sheets against each opposing mold cavity. The split mold is then clamped together to form a pinch off around the perimeter of the hollow cavity thereby forming a molded hollow part still disposed within the clamping tray. Simultaneously, a blow pin inserted into the hollow cavity injects compressed air further presses the heated sheets against the mold cavities. The molded hollow part is allowed to cool to a set point and the vertically oriented split mold is opened. The clamping tray is withdrawn from the split mold and shuttled away from the mold cavities where the molded hollow part is cut away from the clamping tray, still in a vertical position.

    摘要: An adjustable running board comprising an elongated deck having an integrated first end-cap and an underlying support frame in which clamping bolts may be slideably positioned. The elongated deck may be cut to the length required for installation on a particular vehicle. A mounting shoulder on a second end-cap is bolted to the underlying support frame forming the running board assembly.

    摘要: A hydraulically operated ladder brace designed for transporting, for deploying and for supporting a standard, mobile extension ladder and intended to be pivotally attached to a rack system mounted on the rear portion of a vehicle. The ladder brace consists of a U-shaped frame comprising two elongated members and a cross piece operatively connected with a hydraulic ram and cylinder device. In its transport position, the ladder brace is positioned with the U-shaped frame lying substantially in a horizontal plane and pivotally attached to the rack system. The ladder brace is designed such that a standard extension ladder, such as an aluminum ladder having open ended hollow rungs, may be positioned in parallel relationship with and between both of the elongated members. The ladder brace is further designed to allow depolyment from the transport position through activation of a hydraulic pump which causes a ram to extend outwardly from a hydraulic cylinder thus causing the U-shaped frame to pivot the ladder from a horizontal position through an arc into a position of deployment.
