20120152875 | PUSH-BACK CART STORAGE SYSTEM WITH A TOP CART ROLLING ON TOP OF PUSH-BACK RAILS - In a push back cart rack storage system, the top or first cart, as well as the second cart, may be made with less material, and may be significantly simpler and lighter in comparison to existing designs. A push-back cart storage system has a single pair of push-back rails in each lane. A third cart has front and back wheels rolling on a lower inside flange of the push-back rails. A second cart has front wheels rolling on a lower inside cart flange of side rails of the third cart, and has rear wheels rolling on the lower inside flange of the push-back rails. A first or top cart has front and rear wheels rolling on a top surface of the push-back rails. The wheels on the first cart may be inner facing wheels while the wheels on the other carts may be outer facing wheels. The push-back rails and the side rails of the carts may be generally C-shaped channel sections. The top cart and the second cart may be made of angle sections to reduce the weight of the cart and the amount of material needed to manufacture the cart. | 06-21-2012 |
20120125874 | LOW PROFILE PUSH-BACK CART AND PUSH-BACK CART STORAGE SYSTEM - A push-back cart storage system has one or more push-back carts having a cross-member formed by a structural angle section having cutouts at opposite ends to provide clearance for the second push-back cart to move under the first push-back cart. The cross member provides a truss or joist type of beam support having a full height middle section which resists bending and a reduced height at the ends, to provide a low profile. Side members or angle sections on the cart have through holes for attaching wheels, with no welding of wheel mounts required. | 05-24-2012 |
