Embodiment Construction

[0019] Specific embodiments described herein are directed to blow molded plastic structural panels that may be used in, for example, furniture, buildings, vehicles, and other structures. Such as figure 1 , 2 As shown, the blow molded plastic table top 10 is an example of a blow molded panel. The tabletop 10 has a bottom surface 12 from which a plurality of reinforcing rib structures 14 protrude. The reinforcing rib structures 14 are formed integrally on the bottom surface 12 during the blow molding process. Each rib structure 14 extends vertically outward from the bottom surface 12 for various distances, which are referred to herein as heights of various portions of the rib structure 14 .

[0020] Such as figure 1 and figure 2 As shown, the length of the rib structure 14 extends from the first end 20a to the second end 20b. The rib structure 14 varies in height along its length, comprising tall portions 16a, 16b, 16c and short portions 18a, 18b. For example, if image ...

Abstract

A blow-molded surface has a reinforcing rib structure, wherein the height and width of the rib structure vary over its length. For example, the rib structure may have three high sections separated by two short sections, with a gentle slope in height between the sections. The rib structure is preferably wider in the short portion than in the high portion. The lower height of the rib structure at some points increases the stiffness of the plate while allowing less material to be used, since the plastic does not have to flow as deep into the mould at the short sections.

Description

technical field [0001] The present invention relates to plastic structures. In particular, the present invention relates to plastic structures formed by blow molding, and in particular to high strength, low weight blow molded structures for use in furniture and structural panels. Background technique [0002] Various items such as tables, chairs, partitions, walls, and sports equipment, made of plastic. To reduce the weight of items, blow molded plastics are often used. The blow molded plastic structure has an outer wall surrounding the hollow interior. While the hollow interior reduces weight, the hollow interior of such a blow molded article may reduce the strength of the article such that the article cannot support significant weight or force. [0003] It is well known that reinforcing ribs (ribs) made of metal or other durable materials can be added to blow molded structures to increase the load bearing strength of the structure. However, such stiffeners often add si...
