Description
- The present invention relates to storage containers for mounting to vehicles, and in particular to covered external storage containers for trucks.
- Truck bed tool boxes are a common accessory for pick-up trucks which have limited storage capabilities. These boxes are typically designed for outdoor exposure and are mounted in an open bed of the pick-up truck, generally just to the rear of the passenger compartment. The tool boxes have a rectangular open topped receptacle which is covered by one or more lids, which are attached by hinges along an upper edge of the receptacle. The tool boxes also employ lift cylinders to help retain the lid in an open position. For durability purposes, the tool boxes are typically constructed of sheet material with individual panels welded or mechanically fastened to provide the box structure.
- The box lids can encounter repetitive loadings and are therefore susceptible to undesirable deformation. Current lid designs use heavy structural members fastened on the underside of the lid to increase planar rigidity, thereby inhibiting the lid from becoming permanently deformed and therefore misaligned relative to the box. This resistance to deformation inhibits any misalignment that can result in sealing failure between the box and lid, which can result in costly repair or replacement of the tool box.
- One disadvantage with current lid designs is that they are undesirably too heavy to be solely supported by the lift cylinders due to the need for the heavy structural members. U.S. Pat. appl. No. 2001032848 by Giddens et al. describes a lid having a top sheet member, a liner sheet member, and an expanded foam material deposited between the members in a defined interior cavity. Although the lid design by Giddens et al. does not use individual structural members, the presence of the foam can still produce a reinforced lid that is too heavy for support solely by the lift cylinders.
- It is an object of the present invention to provide a composite lid to obviate or mitigate at least some of the above presented disadvantages.
- Truck bed tool boxes are a common accessory for pick-up trucks and are typically designed for outdoor exposure and are mounted in an open bed of the pick-up truck. The tool boxes have a rectangular open topped receptacle which is covered by one or more lids, which are attached by hinges along an upper edge of the receptacle. The tool boxes also employ lift cylinders to help retain the lid in an open position. The box lids can encounter repetitive loadings and are therefore susceptible to undesirable deformation, such that current lid designs use heavy structural members fastened on the underside of the lid to increase planar rigidity, thereby inhibiting the lid from becoming permanently deformed and therefore misaligned relative to the box. The use of additional structural members can make the lids undesirably too heavy to be solely supported by the lift cylinders. Alternatively, a composite lid for a vehicle storage container has an outer sheet metal member including a top portion having a first inner surface with a rim portion extending around a periphery of the top portion. The lid has an inner sheet metal member positioned in a spaced apart relationship to the top portion, where the inner sheet member has a second inner surface opposed to the first inner surface to define an enclosed interior. The lid has a lightweight sandwich panel fixedly secured in the enclosed interior for reinforcing the structural integrity of the lid, where the panel has a corrugated core bonded to the interior of both the inner and outer sheet metal members. The panel can be composed of the corrugated core of a cellulosic honeycomb structure bonded between an upper paper layer and a lower paper layer.
- According to the present invention there is provided a composite lid for a vehicle storage container. The lid comprises: an outer sheet member including a top portion having a first inner surface with a rim portion extending around a periphery of the top portion; an inner sheet member positioned in a spaced apart relationship to the top portion, the inner sheet member having a second inner surface opposed to the first inner surface to define an enclosed interior; and a sandwich member fixedly secured in the enclosed interior for reinforcing the structural integrity of the lid, the sandwich member having a corrugated core bonded on one side to the first inner surface and bonded on the other side to the second inner surface.
- According to a further aspect of the present invention there is provided a method of manufacturing a composite lid for a vehicle storage container. The method comprises the steps of: forming an outer sheet member to include a top portion having a first inner surface and a rim portion extending around a periphery of the top portion; bonding one side of a sandwich member to the first inner surface, the sandwich member having a corrugated core; and bonding a second inner surface of an inner sheet member to the other side of the sandwich member for positioning the inner sheet member in a spaced apart relationship to the top portion, the second inner surface opposed to the first inner surface to define an enclosed interior; wherein the sandwich member reinforces the structural integrity of the lid by having the corrugated core bonded to both the first inner surface and the second inner surface.
