  • Patent number: 4598504
    Abstract: A wall display structure which includes a plurality of ornamental panels, mirrors or other plate-like modular members which are aligned on a surface of a wall of a shop (supermarket) or the like. Transverse channels are formed between each two vertically adjacent modular panels for holding hook elements for hooking articles thereon. Ornamental elements are arranged in the transverse channels so as not to expose the wall surface through the channels.Each transverse channel is defined by support members for mounting the modular panels on the wall at intervals.The support members integrally have a partitioning wall for partitioning the interior of the transverse channel into an element housing for receiving the element and a hook engaging groove for receiving the hook elements.The partitioning of the transverse channel prevents the ornamental element fitted in the ornamental element housing from being damaged by the hook elements mounted in the hook engaging groove.
