In accordance with the present invention, a roller sweeper comprising a handle 11, an extension handle 15, a shank 21 designed and configured to form a frame 28, the frame defining an axle 24, and a unitary cylindrical mounting member 31. In preparation for use an adhesive roller tube 41, or such other similarly designed and configured cleaning attachment, can be frictionally mounted onto the unitary cylindrical mounting member 31 for the removal of debris from a surface. The roller sweeper 10 may be used with or without the extension handle 15 depending on the needs of a user.

(14) Now referring to FIGS. 1, 2, 3A and 3B the present invention includes a handle 11 having a female threaded first end 12 and a second end 13 and an extension handle 15 having a first end 16 and a male threaded second end 17. The threaded second end 17 of the extension handle 15 is designed and configured to detachably engage the female threaded first end 12 of the handle 11 should a user need increased reach when using the roller sweeper. The longitudinally aligned plurality of concave dimples 14 on the handle 11, as well as the shape and size of the handle, provides a user additional grip and comfort when using the present invention. Additionally, a shank 21 extends longitudinally from the second end 13 of the handle 11 of the present invention forming a frame 28 having a proximal end 22 attached to the second end 13 of the handle 11, a distal end 23, a first bent portion 21A, a second bent portion 21B, and a third bent portion 21C. Now referring to specifically to FIGS. 3A and 3B, the shank 21 extends longitudinally from the second end 13 of the handle 11 to the first bent portion 21A of the frame 28 being perpendicular to said handle 11, said first bent portion of said frame 28 continuing to the second bent portion 21B of the frame 28 being parallel to said handle 11, said second bent portion 21B of said frame 28 continuing to the third bent portion 21C of the frame 28 being perpendicular to said handle 11, said, third bent portion 21C of said frame 28 continuing to said distal end 23 of said frame 28. The third bent portion of the frame 28 defines an, axle 24, said axle having an inner end 25 and an outer end 26, the outer end 26 of the axle 24 corresponding to the distal end 23 of the frame 28.

(15) Referring, to FIGS. 2, 3A, 3B, 4A, 4B, to 4C, the present invention includes a unitary cylindrical mounting member 31 designed and configured to be rotatably mounted on the axle 24. The unitary cylindrical mounting member 31 comprising an inner end 39, an outer end 40, a longitudinal channel 32 having a diameter designed and configured to receive the axle 24, a plurality of longitudinal ribs 33 equiangular spaced around said longitudinal channel 32 and radially extending from said longitudinal channel 32 to a unitary cylindrical mounting member surface 34, and an annular recess 35 being defined by the longitudinal ribs 33 located at the outer end 40 of said unitary cylindrical mounting member 31. The unitary cylindrical mounting member surface 34 is designed and configured to frictionally receive an adhesive roller tube 41 including an adhesive layer 42, or such other similarly designed cleaning attachment.

(16) Now referring to FIGS. 2, 3A, 3B, 4B, and 4C, in order to maintain the proper alignment of the unitary cylindrical mounting member 31 on the axle 24 the present invention incorporates a pair of opposing flanges 27 located at the inner end 25 of the axle 24, an inner positional washer 36, an outer positional washer 37, and an axle end cap 38. The inner positional washer 36 and the outer positional washer 37 comprising thrust washers to minimize drag produced between the positional washers and the rotation of the unitary cylindrical member. The axle end cap 38 comprising lock washers, push nuts, and cap nuts. The pair of opposing flanges 27 is located at the inner end 25 of the axle 24 and are designed and configured to engage the inner positional washer 36 thereby preventing the inner positional washer 36 from moving to the second bent portion 21B of the frame 28. The inner positional washer 36 abuts against the inner end 39 of the unitary cylindrical mounting member 31 to prevent movement of the unitary cylindrical mounting member towards the second bent portion 21B of the frame 28. The outer positional washer 37 is designed and configured to engage the outer end 26 of the axle 24 and to abut against the outer end 40 of the unitary cylindrical mounting member 31. The axle end cap 38 is designed and configured to engage the outer end 26 of the axle 24 and to abut against the outer positional washer 37 and thereby preventing the unitary cylindrical mounting member 31 from sliding off the roller sweeper axle 24. The annular recess 35 of the unitary cylindrical mounting member 31 having a depth and a diameter sufficient to house the outer positional washer 37 and axle end cap 38 so that the outer positional washer and the axle end cap when mounted on the outer end of the axle do not extend beyond the outer end 40 of the unitary cylindrical mounting member 31.

(17) The design and configuration of the present invention provides that the invention may be easily manufactured with unitary cylindrical mounting members and axles of different lengths. A preferred embodiment of the present invention is illustrated in FIGS. 1 and 2 depicting the invention having an axle length and a unitary cylindrical mounting member length to accommodate a single 3-inch adhesive roller tube frictionally mounted on the unitary cylindrical mounting member surface. As shown in FIGS. 5A and 5B, alternative embodiments of the present invention are illustrated in which the axle lengths and the unitary cylindrical mounting member lengths accommodate two 3-inch adhesive roller tubes and three 3-inch adhesive roller tubes mounted end to end on the unitary cylindrical mounting members. Additionally, other embodiments of the present invention may include other kinds of cleaning attachments which have been designed and configured to operate in a cylindrical tubular form capable of being mounted onto the unitary cylindrical mounting member of the present invention.

(18) The unique design and configuration unitary cylindrical mounting member of the present invention permit the invention to be easily assembled and operated. To assemble the roller sweeper the inner positional washer is placed onto the axle and moved to a position adjacent to the pair of opposing flanges at the inner end of the axle. Next, the unitary cylindrical mounting member is slid onto the axle by inserting the outer end of the axle into the longitudinal channel located at the inner end of the unitary cylindrical mounting member. Once the unitary cylindrical mounting member is positioned onto the axle, the outer positional washer is placed onto the axle and moved to its position abutting the outer end of the unitary cylindrical mounting member. The axle end cap is next snapped onto the outer end of the axle putting it into position to abut against the outer positional washer thereby keeping the unitary cylindrical mounting member in position on the axle and preventing the unitary cylindrical mounting member from sliding off the axle when the present invention is in use. In a preferred embodiment of the present invention the distal end of the axle together with the axle end cap attached are housed within the annular recess to permit the roller sweeper's use directly against a wall, furniture, or the like. In a preferred embodiment of the present invention a user slides an adhesive cylindrical tube onto the unitary cylindrical mounting member such that the surface of the unitary cylindrical mounting member will frictionally engage the interior cylinder surface of the adhesive cylindrical tube. Once the adhesive cylindrical tube is mounted onto the unitary cylindrical mounting member, the user simply rolls the present invention across the surface to be cleaned. The detachable extension handle permits the user to operate the present invention close in hand or at a distance if needed with the extension handle attached to the handle.

(19) In a preferred embodiment the unitary cylindrical mounting member being manufactured by plastics extrusion for strength and economy. Similarly, the handle and extension handle of the present invention is manufactured from plastic for strength and economy. The shank is manufactured from steel having a diameter of about 5/16 inches.
