    摘要: A decorative merchandise display rack includes a support structure rotatable about a vertical axis and having a plurality of disk-like transparent shelves maintained in spaced, super-posed relation by a series of discrete, stacked, mirrored spacer units, each having pins for coupling the shelves and opposed end portions of adjacent spacer units for rotation as a unit. Opposed cup-shaped members are provided at opposite ends of the support structure and receive the ends of a series of vertically oriented transparent rods which extend through aligned openings provided adjacent the outer peripheral portions of the shelves.

    摘要: A spool assembly of simple, lightweight construction affording efficient, balanced, and inexpensive operation is constructed simply of a pair of end flanges secured to the ends of a hollow exterior tube on which material, such as carpet yarn, may be wound. The tube has interior, longitudinally extending, integral projections that provide longitudinal slots in which self-tapping screws are secured with the heads of the screws retained in the end flanges to secure the flanges on the tube. The slots may be formed by pairs of inwardly projecting walls with the walls retained against spreading by end reinforcing plugs disposed in the ends of the tubes and having peripheral notches that encompass and retain the projecting walls. Alternatively, an interior reinforcing core may be disposed in each end of the tube with radial arms extending partially into the slots for cooperation with the projecting walls to receive and retain the screws. In a variation of the construction, each slot-forming projection may be formed by an intermediate radially projecting wall and an end wall extending at a right angle to the intermediate wall, thereby forming a side-opening slot, and the end walls of the projections may be retained against spreading by end reinforcing plugs that support said end walls against radially inward movement. The tube may be structurally reinforced by intermediate plugs that may be mounted on a central tubular core that receives the spindle on which the spool assembly is to be mounted, or the interior of the assembly between the end flanges and between the central core and the exterior tube may be filled with expanded foam plastic for structural strength. In another embodiment one of the slot forming walls of each pair extends radially inwardly for mounting of the tube directly on a central core that has its ends flared between the extending walls or has wall engaging projections to prevent relative rotation.
