Abstract
A screw eye driving and removing device comprised of a cylindrical member having a vertical slot formed therein. The vertical slot is dimensioned to receive a rounded end portion of a screw eye therein. The cylindrical member has a horizontal slot extending from a position intermediate an upper end and a lower end of the vertical slot. A drill securement portion is secured to the cylindrical member. A screw eye securement portion is secured within the horizontal slot of the cylindrical member.
Claims1
A screw eye driving and removing device for driving and removing screw eyes with the aid of an electric drill comprising, in combination:
- a cylindrical member having a planar upper surface, a planar lower surface, and a cylindrical side wall therebetween, the planar upper surface having a vertical slot formed therein, the vertical slot having a planar upper end and a curved lower end and opposing parallel planar side walls together forming the vertical slot with smaller end walls at right angles thereto, the vertical slot being dimensioned to receive a rounded end portion of a screw eye therein between the opposing planar side walls, the vertical slot having a length about two-thirds the diameter of the cylindrical member and a depth equal to about two-thirds the length of the cylindrical member, the cylindrical member having a horizontal slot extending from a position intermediate the planar upper end and curved lower end of the vertical slot, wherein the cylindrical member is fabricated of steel;
- a drill securement portion comprised of a shaft portion having a first end and a second end, the first end secured to the planar lower surface of the cylindrical member, the second end dimensioned to be received within a nose portion of an electric drill, wherein the shaft portion has a hexagonal cross-section for securement within a nose portion of an electric drill and a length equal to the depth of the vertical slot of the cylindrical member;
- a screw eye securement portion comprised of a male detent element having a spring secured to a distal portion thereof, the male detent element and spring secured within the horizontal slot of the cylindrical member and extending from one side wall toward an opposing side wall, whereby the male detent element engages a central opening in a screw eye upon insertion within the vertical slot, wherein the male detent element is cone shaped and the horizontal slot includes an opening entering into the vertical slot, the cone shaped male detent element further defined by a pointed exterior portion and an annular interior portion, the annular interior portion having a diameter greater than a diameter of the opening and the male detent element thereby precluding the cone shaped male detent element from entering into the vertical slot by way of a planar surface abutment, a free end of the spring abuts a filler material used to fill the horizontal chamber from outside of the cylindrical member with the filler material being formed of a material different from that of the cylindrical member;
- whereby a rounded end portion of a screw eye is inserted into the vertical slot of the cylindrical member thereby pushing the male detent element inwardly of the horizontal slot thus allowing the rounded end portion to be positioned at the curved lower end of the vertical slot causing the male detent to expand outwardly to frictionally contain the screw eye within the vertical slot.
