Abstract: A clip to facilitate a coupling of an object to a suction cup includes a body having a first surface and a second surface disposed opposite to the first surface. The body defines an opening extending from the first surface to the second surface. The clip also includes a tongue adapted to engage with the suction cup and extending inside the opening from the body. The tongue includes a first end attached to the body and a second end arranged at a gap from the body.

Abstract: A shelf has been disclosed, which provides a level with a support bridge, a first vertical support, and a second vertical support. The support bridge, the first vertical support, and the second vertical support forming three points in the level that support an object in alternative right or left arrangements at an angle where the objects extend upward and outward from the support bridge. In particular configurations, each of the first vertical support and the second vertical support comprise a shelving portion and each of the first vertical support and the second vertical support comprise an end support.

Abstract: Suction cups with non-circular peripheral edges are formed with peripheral edges which are of uniform thickness regardless of the radial distance of the peripheral edge from the center of the cup body.

Abstract: Tray units adapted to be mounted on and extend from the front edges of conventional display shelves for supporting and displaying merchandise are provided with mounting support means which attach the tray to the display shelf. The support means includes a first member which extends horizontally from the back side of the tray and a plurality of posts which depend from the first member and extend parallel therewith and rearwardly therefrom. The tray may be simply attached to and supported from the front edge of the shelf by inserting the posts into holes in the shelf so that the first member rests on the top surface of the shelf and the posts rest on the bottom surface of the shelf.

Abstract: A simulated gun launches a retrievable projectile in the form of a cylinder containing a compressible spring. The spring is compressed by inserting the barrel of the gun into the bore of the cylinder. A tab on the end of the cylinder rides in a helical groove on the surface of the barrel to cause the projectile to rotate about the axis of the barrel as the projectile is launched.
