The present invention relates to devices capable of cleaning a variety of surfaces and objects, including floors, chairs, sofas, beds, automobile seats and flooring, clothing, and the like. The mounting of an adhesive roller tube onto a unitary cylindrical mounting member provides a user the ability to remove dirt, hair, lint, and such other debris from numerous surfaces.
Cleaning devices for household and light commercial uses are readily available at hardware stores and such other suppliers of these goods. Many such devices are configured to function as a hand-held roller cleaning device to which an extension handle may be attached to provide a user additional reach for cleaning surfaces that may not be within the user's arm's length.
One limitation of many roller cleaning devices is the number of parts of which the device is comprised. Such parts are prone to malfunction and breakage due to the use of sub-standard materials in the manufacturing of such devices. Additionally, hand-held roller cleaning devices with numerous and complex parts are often difficult to assemble, difficult to use, difficult to maintain, and costly to manufacture. Also, the inherit design and lack of durability regarding the components of many such devices do not support vigorous use when cleaning heavily soiled services.
Accordingly, there remains room for improvement and variation within the art.
It is at least one aspect of the present embodiments of the present invention to provide a roller sweeper comprising a minimum number of durable parts, such invention having a handle, a shank extending from the handle that is designed and configured to form a frame, an axle that is defined by the frame, a unitary cylindrical mounting member, a pair of positional washers, and an axle end cap.
It is at least one aspect of the present embodiments of the present invention to provide a handle having a plurality of longitudinally aligned concave dimples to provide a user comfort and additional grip.
It is at least one aspect of the present embodiments to provide an extension handle that can engage the handle to increase the distance at which the present invention may be used.
It is at least one aspect of the present embodiments to provide a unitary cylindrical mounting member that freely rotates about an axle, the unitary cylindrical mounting member having an inner end, an outer end, a longitudinal channel to receive the axle, a plurality of longitudinal ribs equiangular spaced around and radially extending from the channel to a unitary cylindrical mounting member surface, and an annular recess defined by the longitudinal ribs located at the outer end of said unitary cylindrical mounting member.
It is at least one aspect of the present embodiments to provide a unitary cylindrical mounting member surface to which an adhesive roller tube can be frictionally mounted when using the present invention for the removal of debris from a surface.
It is a further aspect of at least one of the present embodiments to provide a pair of opposing flanges at an inner end of the axle, the opposing flanges designed and configured to engage an inner positional washer that abuts against said inner end of the unitary cylindrical mounting member to maintain its position on the axle.
It is still a further aspect of at least one of the present embodiments to provide an axle having end outer end that is designed and configured to engage an outer positional washer and a detachable axle end cap such that the outer positional washer abuts against the outer end of the unitary cylindrical mounting member and the detachable axle end cap to maintain the position of the unitary cylindrical member on the axle.
It is at least one aspect of the present embodiments to provide a unitary cylindrical mounting member being manufactured from extruded plastic to provide product strength economic production.
It is at least one aspect of the present embodiments to provide unitary cylindrical mounting members and axles having lengths to accommodate mounting one or more adhesive roller tubes.
It is at least one aspect of the present embodiments to provide a shank manufactured from steel and having a diameter of about 5/16 inches.
It is at least one aspect of the present embodiments to provide a handle manufactured from plastic.
It is at least one aspect of the present embodiments to provide an extension handle manufactured from plastic.
These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description and appended claims.

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
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.
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.
Although preferred embodiments of the invention have been described using specific terms, devices, and methods, such description if for illustrative purposes only. The words used are words of description rather than of limitation. It is to be understood that changes and variations may be made by those of ordinary skill in the art without departing from the spirit or the scope of the present invention. In addition, it should be understood that aspects of the various embodiments may be interchanged, both in whole, or in part. Therefore, the spirit and scope of the invention should not be limited to the description of the preferred versions contained herein.
