A sweeping device effectively sweeps snow and the like from variously constructed stairs. The device comprises a handle and wedge-shaped sweeping element or block. The sweeping element is preferably constructed from semi-rigid material and comprises a top side, a bottom side, a back side, a front side, and opposed lateral sides. The top and bottom sides are rectangular and parallel, while the lateral sides are quadrangular thereby defining opposed, anterior and posterior matter-sweeping surfaces. A lower end of the handle is threadably attached to the sweeping block or element for enabling a user to sweep matter such as lightly accumulated snow from stairs via the matter-sweeping surfaces.

I claim: 1. A snow-sweeping device, the snow-sweeping device for sweeping accumulated snow, the snow-sweeping device comprising: an elongate handle, the handle having upper and lower handle ends, the lower handle end being threaded; a wedge-shaped block, the block being constructed from a semi-rigi
I claim: 1. A snow-sweeping device, the snow-sweeping device for sweeping accumulated snow, the snow-sweeping device comprising: an elongate handle, the handle having upper and lower handle ends, the lower handle end being threaded; a wedge-shaped block, the block being constructed from a semi-rigid material and having a top side, a bottom side, a back side, a front side, and opposed lateral sides, the top and bottom sides being rectangular and parallel, the top side having a centralized threaded aperture, the front, back, and lateral sides being quadrangular thereby defining opposed, anterior and posterior snow-sweeping planes angled relative to the top and bottom sides; and a fastener for enhancing fastened attachment of the handle to the block, the fastener having head and pointed fastener ends, the lower handle end being threadably received in the threaded aperture for attaching the handle to the block, the pointed fastener end being received in the lower handle end, the lateral sides ramping up from the bottom side to the top side for enhancing block strength adjacent the lower handle end, a first lateral side being orthogonally angled relative to the top and bottom sides, said first lateral side and the bottom side for sweeping snow from stain having orthogonal and flush tread-to-riser junctions, a second lateral side being non-orthogonally angled relative to the top and bottom sides, said second lateral side and bottom side for sweeping snow from stairs having orthogonal and staggered riser-to-tread junctions, said semi-rigid material enabling block flexibility adjacent the bottom side, the handle enabling a user to sweep accumulated snow via the snow-sweeping planes, the block flexibility for enabling squeegee action while sweeping accumulated snow via the snow-sweeping planes. 2. The snow-sweeping device of claim 1 wherein the back side is orthogonal to the top and bottom sides for enabling the user to selectively sweep snow from a riser-to-tread junction past a tread terminus. 3. A stair-sweeping device, the stair-sweeping device for sweeping matter from stairs, the stair-sweeping device comprising: an elongate handle, the handle having upper and lower handle ends; and a wedge-shaped block, said block having a top side, a bottom side, a back side, a front side, and opposed lateral sides, the top and bottom sides being rectangular and parallel, the lateral sides being quadrangular thereby defining opposed, anterior and posterior matter-sweeping surfaces angled relative to the top and bottom sides, the lateral sides ramping up from the bottom side to the top side for enhancing block strength adjacent the lower handle end, the lower handle end being attached to the block for enabling a user to sweep matter from stairs via the matter-sweeping surfaces, the front and back sides being quadrangular, a first lateral side being orthogonally angled relative to the tap and bottom sides, said first lateral side and bottom side for sweeping matter from stairs having orthogonal and flush tread-to-riser junctions, a second lateral side thus being non-orthogonally angled relative to the top and bottom sides for sweeping matter from stairs having orthogonal and staggered riser-to-tread junctions. 4. The stair-sweeping device of claim 3 comprising a fastener, the fastener for fastening the handle to the block for enhancing handle-to-block attachment. 5. The stair-sweeping device of claim 3 wherein the lower handle end is threaded and the top side comprises a threaded aperture, the lower handle end being threadably received in the threaded aperture for attaching the handle to the block. 6. The stair-sweeping device of claim 3 wherein the block is constructed from a semi-rigid material, said semi-rigid material enabling block flexibility adjacent the bottom side, the block flexibility for enabling squeegee action while sweeping matter via the matter-sweeping surfaces. 7. The sweeping device of claim 3 wherein the back side is orthogonal to the top and bottom sides for enabling the user to selectively sweep matter from a riser-to-tread junction past a tread terminus. 8. A sweeping device, the sweeping device for sweeping matter from surfaces, the sweeping device comprising: an elongate handle, the handle having upper and lower handle ends, the lower handle end being threaded; a wedge-shaped block, the block being constructed from a semi-rigid material and having a top block portion, a bottom block portion, a top side, a back side, a front side, and opposed lateral sides, the top block portion having a threaded aperture, the lateral sides defining anterior and posterior matter-sweeping surfaces angled relative to the top side, the lower handle end being threadably received in the threaded aperture for threadably attaching the handle to the block, the lateral sides ramping up from the bottom portion to the top portion for enhancing block strength adjacent the lower handle end, the semi-rigid material enabling block flexibility adjacent the bottom portion, the handle for enabling a user to sweep matter via the wedge-shaped block, the semi-rigid material for enabling squeegee action while sweeping matter, the front and back sides being quadrangular, a first lateral side being orthogonally angled relative to the top side for sweeping matter from stairs having orthogonal and flush tread-to-riser junctions, a second lateral side thus being non-orthogonally angled relative to the top side for sweeping matter from stairs having orthogonal and staggered riser-to-tread junctions. 9. The sweeping device of claim 8 wherein the back side is orthogonal to the top side for enabling the user to effectively sweep matter from a riser-to-tread junction past a tread terminus.
