摘要： The present invention pertains to a ladder. The ladder includes a first plastic side rail, at least a portion of which is hollow. The ladder also includes a second plastic side rail, at least a portion of which is hollow. The second side rail is in parallel with the first side rail. Additionally, the ladder includes a plurality of steps, each of which is attached to the first and second side rails at predetermined locations such that each step forms a flat weight bearing platform upon which a user can stand. The first and second side rails each have a plurality of pockets having solid cross sections disposed therealong at predetermined positions, and each of the steps are attached to the first and second side rails at corresponding pockets therein with fasteners through holes in the solid cross sections. The present invention also pertains to a stepladder. The stepladder includes a first side rail. The stepladder also includes a second side rail adjacent to and in parallel with the first side rail. There are a plurality of steps, each of which is attached to the first and second side rails at predetermined locations such that each step forms a flat weight bearing platform upon which a user can stand. The first and second side rails and the steps form a front section. Additionally, there is a third side rail adjacent to the first section. There is also a fourth side rail adjacent to and in parallel with the third side rail. The stepladder also includes a first bracing element attached to the third and fourth side rails to support them. The third and fourth side rails and first bracing element define a rear section. Moreover, there is a top which is connected to the front and rear sections at the top ends of the first and second rails, and the top ends of the third and fourth rails such that the front and rear sections form a V-shape when deployed and fold on top of each other when undeployed. The stepladder also includes a shelf in pivotal relationship with respect to the front and rear sections such that when the front and rear sections are deployed, the shelf automatically extends essentially perpendicularly with the front and rear sections, and when the front and rear sections are folded on top of each other to be undeployed, the shelf automatically folds into an essentially parallel position with respect to the front and rear sections.

摘要： A molded rectangular top component of a stepladder is disclosed which incorporates an improved method of securely supporting a bucket or paint can at the top of the ladder. A recess in a second wall of the laddertop corresponds to and accommodates the arcuate shape of the bail of a bucket, and a hook is attached at the lower portion of the recess, which has the beneficial effect of moving the weight closer to the center of the ladder than on a protruding hook. The ladder top includes at least one slot in a first wall which extends from the ladder top through which accessories can be attached. The first wall opposes the second wall.

摘要： The present invention pertains to a plastic ladder. The plastic ladder includes a front section which has a first hollow side rail and a second hollow side rail disposed essentially in parallel with the first side rail. The first and second side rails are made of plastic and have reinforced pockets disposed along the respective rails at predetermined locations. The plastic ladder also has a plurality of hollow plastic steps. Each of the steps is attached to the first and second rails at corresponding reinforced pockets therein such that each step forms a flat weight bearing platform upon which a user can stand. Each step has blow molded tread patterns which provide a slip resistant surface. The ladder also has a rear section comprised of a third hollow plastic side rail and a fourth hollow plastic side rail disposed essentially in parallel with the third hollow plastic side rail. The third and fourth hollow plastic side rails have reinforced pockets disposed along the respective rails at predetermined positions for attaching a plurality of hollow plastic bracing elements.

摘要： Methods, systems, and computer program products sustain a fleet of configuration-controlled assets. The method involves integrating a plurality of previously separate systems with reusable business transactions associated with managing a fleet of vehicles. The method also involves receiving operational data associated with a vehicle of the fleet, integrating the operational data per customer requirements, packaging and distributing the operational data to the plurality of systems, and installing and distributing the operational data to one or more applications of the plurality of systems utilizing reusable business transactions. The system utilizes a plurality of applications and a plurality of logical subsystems, which are connected to each other through gateways. The logical subsystems use a common format defined by a set of messages. However, the applications can use a plurality of different formats. The gateways, which are the connecting blocks, convert the data flow between the logical subsystems and the applications.
