Abstract
An apparatus for removing debris from a target surface. The apparatus comprises a hollow roller with a supply roll and take-up roll axially rotatably disposed within the volume of the hollow roller. A sheet material, such as adhesive tape, extends from the supply roll through a slot, around the periphery of the roller at least 180°, back into the slot and onto be take-up roll. A partition separates the supply roll and take-up roll, reducing contamination of tape on the supply roll. An index mechanism may be provided to advance the tape one path length from the supply roll to take-up roll, the user does not overuse or underuse fresh tape.
Description
- The invention relates to devices will removing debris from a target service, and more particularly to devices which internally contain such debris.
- Devices for removing debris from a target surface are well known. Certain types of debris, such as lint and pet hair, have specialized devices for removing and disposing of such debris.
- Early attempts to make such devices included simple rollers with adhesive-coated sheets. The user rolled the sheets across the target surface, contacting and simply picking up the debris therefrom. However, such attempts have not been satisfactory. The user must remove the sheet it becomes contaminated. The sheet may not be properly separated from the balance of the roll—due to the need to have sufficient adhesion on the next sheet in order to pick up debris from the target surface. As the diameter of the roll becomes smaller, due to successive removal of the outer sheets, contamination occurs more quickly in the cycle repeats itself. Examples of such attempts are found in U.S. Pat. Nos. 4,905,337; 5,027,465; 6,763,977; 6,688,464; and 7,186,207.
- One attempt to overcome the problems associated with the simple roller devices is found in US publication 2006/0265823. This attempt shows a device or cleaning a fabric surface of debris having to rollers selectively in contact with one another and a central opening therebetween. However, this attempt teaches a dirt collection chamber which must be emptied.
- Yet other attempts are found in U.S. Pat. Nos. 4,083,075; 6,735,806; 6,859,976. These attempts disclose apparatus having a cleaning material disposed between a supply roll and take-up roll. A portion of the cleaning material is configured to create a particle trap. The supply roll, take-up roll and cleaning material may be included as a unit in a removable cartridge. However, this attempt makes no provision to prevent cross-contamination between the take-up real and supply roll.
- Attempts to overcome the problems associated with the foregoing, include placing the supply roll and take-up roll internal to a cylindrical housing. One attempt includes U.S. Pat. No. 4,575,890 which interposes a rotatable gear between the reels, promoting contamination of the supply roll. Other attempts with a cylindrical housing include U.S. Pat. No. 4,640,539; and U.S. Pat. No. 6,343,397.
- Yet another attempt is shown in US 2006/0254017. This attempt utilizes a supply roll and take-up roll, but fails to utilize either a cylindrical housing or the housing periphery to carry the cleaning material. However, the need for improved cleaning apparatus continues.
- The invention comprises an apparatus for removing debris from a surface. The apparatus has a longitudinal axis and comprises a roller having an exterior periphery. The roller can receive a supply of sheet material therein. The sheet material can extending through a slot to overlie the periphery of the roller, and wrap around said roller to subtend at least 180° thereof; and reenter said interior volume through the slot to a collection chamber.

FIG. 1 , the invention comprises anapparatus 10 having ahousing 11 and aroller 15 therein. Thehousing 11 may have ahandle 12 attached thereto for ergonomic convenience. - Referring to
FIGS. 2-3 , theroller 15 is hollow, may be generally cylindrical, elliptically shaped, etc. and may have two longitudinallyopposed end caps 13. Theperiphery 16 of theroller 15 has been axially extendingslot 20 therethrough. Theslot 20 allows for passage oftape 40 between theinternal volume 17 and the external for a free of theroller 15. Theslot 20 further allows for collection of debris from the target surface to theinternal volume 17 of theroller 15. - Inside the
roller 15 is asupply roll 22 and optionally a take-up roll 24. Thesupply roll 22 and optional take-up roll 24 maybe cantilevered from oneend cap 13 or, as shown, may be rotatably joined to eachend cap 13. Atape 40 extends from thesupply roll 22 to the take-up roll 24. - The
roller 15,supply roll 22 and/or take-up roll 24 may be made of kraft grade cardboard. This arrangement provides a relatively inexpensive manufacture for that assembly. Such assembly, including thetape 40 may then be supplied as a unitary cartridge. The cartridge may be discarded after a single use or thetape 40 therein may be replenished. - The
tape 40 in a subsequent use may be the same as or different than the discardedtape 40. Alternatively or additionally, thetape 40 may have different zones with different properties. The different zones may be spaced across the width of thetape 40. For example, the outboard zones of thetape 40 may have different adhesive properties than the center section. Alternatively or additionally, thetape 40 may have different zones with different properties spaced serially throughout its length. This arrangement automatically provides for different debris removal properties throughout the life of thetape 40. - The
tape 40 may be relatively thin, the increase the supply available before it si necessary to replenish. Thetape 40 may have a thickness of less than or equal to about 0.1 mm. The carrier film of thetape 40 may be made of synthetic material, such as PE. The synthetic carrier film minimizes fold-over and may provide a static charge which also attracts debris. - A
partition 30 is disposed intermediate thesupply roll 22 and the take-up roll 24. Thepartition 30 has opposed first and second ends. Either or both end may be joined to itsrespective end cap 13. Thepartition 30 further has aninternal side edge 32 and anexternal side edge 34 opposed thereto. Thepartition 30 may be generally planar as shown, or, alternatively, may be curved. - The
partition 30 may bisect the interior volume of theroller 15 into two chambers or may be offset relative to thesupply roll 22 and take-up roll 24. Thepartition 30 may be coincident a radius of theroller 15 or may be angularly disposed relative to a radius of theroller 15. - Likewise, the
partition 30 may conceptually divide asingle slot 20 into two slots: afirst slot 20 associated with afirst chamber 18, through which thetape 40 exits the volume of theroller 15 and asecond slot 20 through which thetape 40 re-enters the volume of theroller 15 into asecond chamber 19. - The
external side edge 34 of thepartition 30 may extend to theperiphery 16 of theroller 15 or theexternal side edge 34 may be internal to theperiphery 16 of theroller 15, as shown. Theinternal side edge 32 of thepartition 30 may be juxtaposed with, and in a degenerate case, coincident the center of theroller 15. If desired, thepartition 30 may extend through the center of theroller 15 approximating a diameter. However, if thepartition 30 is attached to the inside wall of theroller 15 generallyopposite slot 20, thepartition 30 must allow for the passage oftape 40 between the twochambers roller 15. - The
partition 30 may be stationary, to prevent contamination associated with movement thereof. Thepartition 30 may be generally planar. If thepartition 30 is generally planar, it may be oriented generally perpendicular to a line connecting the axes of the take-up roll 24 and thesupply roll 22. This geometry maximizes the area presented to contamination on the take-up roll 24. Alternatively, thepartition 30 may be oriented generally concave towards the take-up roll 24 so as to hold contamination away from thesupply roll 22. - Referring to
FIG. 3A , thepartition 30 may be concave and bistable. Abistable partition 30 may initially be oriented concave towards the take-up roll 24 or thechamber 19 where spenttape 40 and debris accumulates. As material accumulates in thatchamber 19 the pressure of that material against thepartition 30 may invert to be oriented concave towards thesupply roll 22. This arrangement provides the advantages of shielding thesupply roll 22 from debris in the other chamber, and accommodating the increase in volume oftape 40 on the take-up roll 24 with the concomitant decrease in volume of thesupply roll 22. - If desired, the
tape 40 may have a relatively low release adhesion against thepartition 30. Thepartition 30 may be made of kraft grade cardboard and have a release coating or may be made of low friction plastic, such as LDPE. The partition may provide less than 280 grams per 2.54 centimeters adhesion, less than 140 grams per 2.54 centimeters adhesion, or less than 28 grams per 2.54 centimeters adhesion againsttape 40. This arrangement prevents thetape 40 from unduly sticking to thepartition 30. Thetape 40 may have a greater pickup adhesion against the target surface. An adhesion of at least 113 grams per 2.54 centimeters, least 170 grams per 2.54 centimeters, or least 226 grams per 2.54 centimeters as measured against stainless steel according to ASTM D333. This arrangement provides sufficient adhesion to remove debris from the target surface, but interfere with operation of theapparatus 10. - Referring back to
FIGS. 2-3 , alternatively, thepartition 30 may be hinged, to float with increasing accumulation of material in the chamber receiving debris and usedtape 40. The hinge may be proximate theexternal side edge 34 of thepartition 30. - The desired circumferential width of the
slot 20 may be adjusted to provide the desired amount of contact of theperiphery 16 of theroller 15 with the contact surface. As the subtended angle of theslot 20 increases, there is less contact area of thetape 40 available to remove debris from the target surface. As the subtended angle of theslot 20 decreases, there is less room for debris andtape 40 to pass therethrough. - The
slot 20 may be parallel the axis of theroller 15 as shown. Alternatively, theslot 20 may have a slight chevron shave, to accommodate differences in tension between the ends and center oftape 40. If desired, prophetically theroller 15 may have a slight barrel shape, to improve tracking of thetape 40. Alternatively, a slight hourglass shape may be used for theroller 15. - If desired, a
rotatable idler roll 38 may be juxtaposed with either or bothedges slot 20. Theidler roll 38 can minimize tearing of thetape 40 against the edges of theslot 20 and provide for smoother transmission of thetape 40. The idlers rolls 36 may be joined to either or bothend caps 13. - In operation the
tape 40 follows a predetermined path from thefirst chamber 18, containing thesupply roll 22, to thesecond chamber 19 containing the take-up roll 24. Particularly, thetape 40 may unwind from thesupply roll 22 and, under tension, be transported to the edge of theslot 20, and anyidler roll 38 juxtaposed there with. Thetape 40 then wraps around theperiphery 16 of theroller 15 and reenters the volume of theroller 15 at the other edge of theslot 20. Thetape 40 particularly reenters theroller 15 into thesecond chamber 19. If a take-up roll 24 is not present, thetape 40 may simply accumulate in thesecond chamber 19 and later be discarded. - When wrapped around the
periphery 16 of theroller 15, thetape 40 may subtended an angle on the exterior surface of theroller 15 of at least about 180°, 270°, 300°, 330° or 350°. As the subtended angle increases,more tape 40 is presented to the target service. As the subtended angle decreases, the width of theslot 20 becomes more significant, potentially allowing collected debris to fallout of thesecond chamber 19 and be redeposited on the target surface if such debris is not adequately captured by thetape 40 adhesive. - In use, the
tape 40 is stationary while removing debris from the target surface. When thetape 40 becomes too contaminated to be efficacious, thetape 40 may be indexed on a path length. A path length is the distance from thesupply roll 22, around the subtendedperiphery 16 to the take-up roll 24. The path length is expected to remain relatively constant throughout the life of thetape 40 supply. Astape 40 is depleted from thesupply roll 22 an approximately corresponding amount oftape 40 will be added to the take-up roll 24. If desired, the take-up roll 24 may be provided with a manual knob, to provide for properly tensioning thetape 40 web, as needed. - Referring to
FIG. 4 , theapparatus 10 may comprise an index mechanism for indexing thetape 40 supply one path length. This index mechanism assures relatively constant and path length is used during the life of thetape 40 supply. The index mechanism also provides convenience for the user, to prevent a partial path length from being utilized and reuse of contaminatedtape 40 or more than a path length from being used and wastingunused tape 40. - The index mechanism may be disposed outboard of either
end cap 13. If desired, the index mechanism may be contained in a pod, to minimize contamination of moving parts and prevent a pinch hazard. - The index mechanism may comprise a rotatable crank 50 for advancing the
tape 40 path. Optionally, thecrank 50 may articulable between a cranking position and an in-use position. The in-use position may provide for thecrank 50 to be tucked against anend cap 13 and ergonomically out of the way while theapparatus 10 is in-use and collecting debris from a target surface. - The crank 50 may rotatably advance a
drive shaft 52. Thedrive shaft 52, in turn, is not coincident the centerline of theroller 15 and may be juxtaposed with theperiphery 16 thereof. Manual rotation of thecrank 50 may, in turn, rotate aring gear 54, which, in turn is joined to acorresponding end cap 13. Thedrive shaft 52, in turn, may be coupled to the take-up roll 24. - Rotation of the
crank 50 causes rotation of the take-up roll 24 throughoptional gearing 54. The crank 50 may be geared such that an integer rotation thereof provides for indexing of thetape 40 path so that one path length is advanced. Of course, one of skill will recognize that instead of a manual crank 50 for advancing thetape 40, an electric motor may be utilized. - The
tape 40 may comprise any suitable adhesive disposed on a carrier film. The carrier film should have sufficient tensile strength to prevent tearing during advance throughout the path length. The film should be sufficiently thin to allow an adequate supply to be conveniently contained in theroller 15 volume. - While the
apparatus 10 has been described for use with target surfaces such as couches, upholstery, etc., for lint and hair removal, the invention is not so limited. Theapparatus 10 may be used to clean hard surfaces, such as windows, countertops, etc. If desired, thetape 40 may be pre-wetted and apply a cleaner to the target surface. Thetape 40 may further comprise hook material, in addition to/instead of thetape 40 adhesive. Allsuch tapes 40, pre-wetted materials, films, etc. are interchangeably referred to herein astape 40 or sheet material. - The
supply tape 40 may be provided core wound, coreless wound, z-folded, etc. Thetape 40 supply may be inserted into thefirst chamber 18 as supplied in a clip. - Referring to
FIG. 5 , if desired, theapparatus 10 may further comprise a caddy 60 for convenient storage. The caddy 60 may comprise twooutboard wings 64 hingedly attached to acentral base 62. Thewings 64 may articulate inwardly, in the direction of the arrows when theapparatus 10 is inserted into the caddy 60. In this manner, thewings 64 may enclose theapparatus 10 when inserted therein. This arrangement provides for aesthetic storage and protection of theapparatus 10 in the caddy 60 when it is not in use. - The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
