Abstract
The preferred clip is comprised of a hub with four equally spaced arms, each having at least one coin-engaging slot. Coins are retained by frictional engagement and by cooperation between the residual coin rim and ridges in the slots. Structures may be built of coins that are in orthogonal or parallel relationship. Coins of more than one size (denomination) can be retained by a single clip.
Claims13
A structural interconnection clip for joining display elements where the display elements have at least a portion configured as a tab, the tab having a substantially planer and parallel opposed surface comprising:
- a clip having a hub;
- said hub having an axis;
- a plurality of arms protruding from the opposite ends of said hub lying in plane parallel to each other from said hub, each of said arms having a slot wherein one or more retention ridges and stops are disposed in said slot, which ridge is sized to receive and retain the tabs on the structural display elements, and which stop is a depression at the base of the slot sized to correspond to the outer diameter of the largest tab to be retained,
- a plurality of said slots intersect said axis and are arranged at right angles, one to the other.
A coin interconnection clip for joining a plurality of coins into a display structure comprising:
- a clip having a hub;
- said hub having an axis;
- a plurality of arms radiating from the opposit ends of said hub lying in plane parallel to each other from said hub, each of said arms having at least a primary slot,
- each of said slots lying on intersecting planes, and each of said intersecting planes passing through said axis of said hub;
- said slots comprising means for supporting coins, and to grip and releasably retain at least one denomination of coin.
A coin clip for joining and supporting a plurality of coins, and comprising:
- a clip having a hub,
- a plurality of arms radiating from the opposit ends of said hub lying in plane parallel to each other from said hub, each of said arms incorporating a slot,
- the slot in each of said arms lying along a plane which passes through the hub of said clip and which intersects the planes along which the other slots lie,
- said arms comprising a pair of opposed tension arms, each of said tension arms carrying a dependent, reflex, engagement finger, each of said fingers being substantially parallel to each of said tension arms, whereby coins of the thinnest thickness do not substantially flex said tension arms, but do engage said reflex engagement finger, providing a substantial area of contact with said coin, whereas coins of the thickest dimension designated to be supported by the clip substantially flex said tension arm, and are also engaged by said reflex engagement finger.
