  • Publication number: 20220412158
    Abstract: A flanged interlocking molding is provided for use in toilet partitions or other partitions, and which eliminates the sight lines along each edge of the partition door. The flanged interlocking molding, formed of a single piece of material can be arranged on a component of the partition, such as a door and/or a pilaster. The flanged interlocking molding comprises a body portion; a first arm extending from a first edge of the body portion; a flange comprising include parallel layers of the metallic material including a first layer extending in a first direction away from the body portion, and a second layer extending from the first layer in a direction opposite the first direction; and a second arm extending from the second layer of the, the second arm including an edge arranged parallel to an edge of the first arm with a gap formed therebetween.

  • Publication number: 20220410237
    Abstract: A method for manufacturing an apparatus, such as a flanged interlocking molding for use in partitions such as restroom partitions is provided. The method comprises providing an elongated strip of a metallic material having a flat profile to a device comprising a roll former comprising a plurality of dies in series, each of the plurality of dies being configured to modify a profile of the elongated strip; and modifying the profile of the elongated strip from the flat profile to a profile comprising a plurality of profile segments separated by bends in the metallic material, by passing the elongated strip through the plurality of dies sequentially to define the profile. The profile segments include segments corresponding to a first arm, a body portion, a first flange layer, a second flange layer, a second arm of the apparatus.

  • Publication number: 20020149161
    Abstract: A system and method for reducing vehicle rollover risk by automatically adjusting or tilting, in response to sensed driving conditions, the position of a vehicle body relative to a vehicle chassis (14) so as to shift the vehicle's COG and thereby compensate for or counteract dangerous centrifugal forces acting on the vehicle due, for example, to cornering or high-speed maneuvering. The system broadly comprises a computer (20); a plurality of sensors (22); front and rear controllers (24,25); and four or more height adjusters (26). The computer (20), in response to input from the sensors (22), commands the front and rear controllers (24,25) to cause the hydraulic or pneumatic height adjusters (26) to adjust the vehicle body's position so as to counteract rollover-inducing forces. The sensors (22) include steering (30), sway (32), speed (34), and angle-measuring (36) sensors.
