Abstract:
1. An expansible sanding block for supporting an exteriorly mounted looped sanding belt, comprising: an elongate and substantially planar shaped base exhibiting a bottom extending belt supporting surface; a cover exhibiting first and second oblique extending belt supporting surfaces establishing a peaked configuration and engageable with said base in mutually linearly extensible fashion to collectively define a three-dimensional article for supporting the sanding belt; and a trigger extending between abutting locations of said base and cover communicable with a widthwise interior passage defined in said three dimensional article, said trigger being displaced in a first lateral direction to lengthwise displace said cover in a first extensible direction relative said base and to tauten the belt, said trigger displacing in a second and opposite lateral direction to reverse displace said cover relative said base to loosen the belt, wherein said trigger exhibits a rectangular shape and further comprises an elongate aperture defined along a side surface and within the trigger is defined a ramp surface, the base having a fixed end projection that projects inwardly of said aperture, said end projection traveling along said ramped surface, during lateral translation of said trigger, causing said trigger and slidably engaged cover to lengthwise translate in the selected displacing direction.
