Publication number: 20140054916Abstract: A composite commercial walk-in van body is constructed via lightweight, composite structures. A composite floor structure having integral logistic tracks are joined to composite sidewalls that include integral rub rails that also integrally formed logistic tracks on an interior thereof. Pigment molded lower body panels that extend beyond the sidewalls are fully replaceable to enhance durability and maintenance of the walk-in van body. A one-piece molded roof eliminates leaks. Any necessary rivets are captured so as to prevent any wet-to-dry surface penetration. An easily accessible washer fluid and brake fluid reservoir aid in the maintenance and operability of the walk-in van body. Such elements contribute to substantial weight reduction, and increase in durability, functionality, and fuel economy of walk-in vans utilizing such a composite body.Type: ApplicationFiled: September 6, 2013Publication date: February 27, 2014Applicant: Spartan Motors, Inc.Inventors: John E.

Patent number: 6487979Abstract: A stowable shelf assembly for use in a vehicle. The shelf assembly has a shelf and a bracket. The shelf has a first flange and a brace member each extending outwardly from the shelf. The shelf is also movable between use and stowed positions. The bracket has a second flange and a support, each extending outwardly from the bracket. The first flange of the shelf is located between the second flange and the support. The first flange abuts the second flange, the shelf is carried by the support and the brace member is adjacent the bracket while the shelf is in the use position. Conversely, the first flange is spaced apart from the second flange, the shelf is spaced apart from the support and the brace member is spaced apart from the bracket while the shelf is in the stowed position.Type: GrantFiled: March 15, 2001Date of Patent: December 3, 2002Assignee: UtilimasterInventors: David L.

Patent number: 6062975Abstract: A ventilation system for a vehicle to pressurize the cargo area of the vehicle including a duct mounted adjacent the top wall of the vehicle cab with a first end in flow communication with an opening in the front wall of the vehicle, and a second end in flow communication with the cargo area of the vehicle. An adjustable damper is disposed within the duct adjacent the first end. The damper is adjustable between a closed position and an opened position to adjust the amount of air flow through the duct. The center portion of the duct includes a plurality of apertures to direct a portion of the air flowing through the duct into the cab. The lower wall of the center portion includes a plurality of diagonal channels to collect water and direct it to a drain adjacent the first end of the duct. A fan is mounted within the duct to provide air flow into the cargo area when the vehicle is not moving. A filter is also mounted within the duct to prevent dust and particulate matter from entering the cargo area.Type: GrantFiled: March 13, 1998Date of Patent: May 16, 2000Assignee: Utilimaster CorporationInventor: John E.
