    Abstract: A footwear rack and clasp for storing footwear are provided. The clasp comprises a hook, a plurality of coplanar arms downwardly extending from the hook, and at least one tong. The tong is pivotally coupled to a first coplanar arm and extendable across an opening defined by the first coplanar arm and an adjacent second coplanar arm to engage the second coplanar arm. A biasing force exerted by the tong on an article to be hung is increased proportionally as the weight of the article increases. The footwear rack comprises a vertical post supporting a plurality of removeable footwear support arms and a plurality of clasps removably attachable to the arms. Each support arm extends in a direction that is generally perpendicular to a longitudinal axis defined by the post.

    Abstract: The invention proposes a suspension-type conveying arrangement in the case of which conveyable-article carriers (1) are supported, by way of running rollers (9) on guide rails (3) for movement along a conveying route. Arranged on a drag chain/drive chain (15) guided along the conveying route are driver elements (17), preferably brush elements (17), which can be moved between a driving position and a non-driving position. The invention proposes various concepts in order, in the case of a build-up of conveyable-article carriers (1), to transfer the driver elements (17) into the non-driving position, with the result that they act on the built-up conveyable-article carriers (1) at most to a slight extent, if at all. In the driving position, it is possible for driver elements (17) to act on the conveyable-article carriers (1) in order to drive them along the conveying route.

  • Patent number: 4144817
    Abstract: A trolley conveyor comprising a hollow guide rail within which an endless conveyor chain is centrally supported by guide rollers. A plurality of spaced U-shaped hangers supported by said chain extend through a longitudinal opening in one side of the guide rail spaced above the bottom of the rail. The lower side of the guide rail below the opening is inclined outwardly and serves to contain foreign matter present within the guide rail as well as to catch matter falling from above. The hangers each include a projection adjacent the longitudinal opening which serves to prevent the splashing of foreign matter from the interior of the guide rail out through the opening.
