Abstract
A universal drill stand for supporting a hand-held drill in an elevated and inverted position for drilling holes or inserting fasteners into a concrete ceiling or other overhead surface. The universal drill stand is extendable for use with varying ceiling heights. It eliminates the need for a worker to construct scaffolding or ascend a ladder or other elevating device to drill each hole, allowing the worker to remain safely on the floor and away from dust and debris associated with the drilling.
Claims17
A universal drill stand apparatus comprised of:
- a vertically telescoping pole assembly comprising an outer vertical tube, the outer vertical tube having at least one internal spline, and the assembly further comprising at least one inner vertical tube, the at least one inner vertical tube comprising at least one external spline and at least one internal spline;
- wherein said outer vertical tube encloses a portion of the at least one inner splined vertical tube, the external spline of said at least one inner splined vertical tube mating with the internal spline of the outer splined vertical tube and wherein the at least one inner splined vertical tube comprise an uppermost portion;
- at least one splined tube locking assembly to selectively secure and release said inner splined vertical tube relative to said outer splined vertical tube and to vertically set the at least one inner splined vertical tube in a fixed position relative to said outer splined vertical tube;
- the uppermost portion of one of the at least one inner vertical tube comprising a collar having a top cover, the top cover further comprising at least one aperture defined in the top cover;
- a tripod assembly comprised of a leg bracket, three collapsible leg members, three brace member pairs and a base bracket, each of the collapsible leg members having a top end and a bottom end, wherein the top end of each leg member is attached to the leg bracket and wherein a caster is attached to the bottom end of each leg member, the leg bracket encircling the outer splined vertical tube such that the leg bracket is movable along the outer splined vertical tube, and the base bracket is fixedly secured to the bottom of the outer splined vertical tube;
- a drill saddle comprising a near vertical portion that is flanked by opposing side support portions and a near horizontal portion that is flanked by opposing bottom support portions;
- at least one fastener for attaching the drill saddle to the top cover of inner vertical tube collar;
- at least one securing component which secures a hand-held drill to the near vertical portion and side support portions of the drill saddle;
- and
- a drive motor assembly for vertically elevating the drill saddle from an unextended position to an extended position for drilling a hole into a concrete ceiling or other overhead surface.
A universal drill stand for use with a drill, the stand comprising:
- a vertical wash-down pneumatic cylinder having an uppermost portion;
- a horizontal base for supporting the vertical cylinder;
- a pole clamp offset disposed at the uppermost portion of the vertical cylinder;
- an offset tube disposed within the pole clamp offset and having an uppermost portion;
- a drill saddle disposed at the uppermost portion of the offset tube;
- and
- means for actuating the cylinder to elevate the offset tube and drill saddle for drilling a hole into a concrete ceiling or other overhead surface.
A universal drill stand for use with a drill, the stand comprising:
- a movable horizontal base;
- a vertical inner cylinder secured to the base;
- a vertical outer cylinder, the outer cylinder being movable vertically;
- an uppermost portion to the outer cylinder;
- a pole clamp offset disposed at the uppermost portion of the outer cylinder;
- an offset tube disposed within the pole clamp offset and having an uppermost portion;
- a drill saddle disposed at the uppermost portion of the offset tube;
- and
- means for actuating the outer cylinder to elevate the offset tube and drill saddle for drilling a hole into a concrete ceiling or other overhead surface.
