Abstract:
1. A retainer apparatus for removably engaging a first article to a second article, the second article being capable of magnetic attraction and having an aperture therethrough, said apparatus comprising: (a) a beam having a longitudinal axis, said beam including a first end portion and a second end portion wherein said longitudinal axis spans therebetween said first end portion and said second end portion, said first end portion is affixed as an open ended hook having an inside surface that faces inward toward said beam, said open ended hook terminates as a cantilever, said open ended hook is solely removably engagable with the second article aperture, by contact with said cantilever and said hook inside surface, said beam first end portion is adapted to attach to the first article; (b) a finger that is pivotally connected to said second end portion, said finger only having pivotal movement disposed completely within said hook inside surface as between an open state position allowing free passage of said hook through the aperture, and said finger also having a closed state position wherein said finger is in contact with said hook inside surface to said hook such that said hook and finger form a converging interface, said converging interface has an entrance opening that encompasses a centroid of the second article, wherein said finger has a magnetic surface resulting in said converging interface having a single magnetic surface when in said closed state, said magnetic surface is in contact with said hook inside surface; and (c) a means for urging said finger from said open state position to said closed state position, wherein operationally said retainer apparatus removably engages the first article to the second article when said finger and the second article are magnetically attracted to one another with a manual application of a single force in a direction to further the second article into said converging interface with the second article placing said finger into said open state with said finger returning to said closed state upon the second article passing through said converging interface and onto said hook resting upon said hook inside surface resulting in engagement of the first article to the second article.
