Description

FIELD

This application relates to systems and methods for providing a cleaning cart with a sweeping attachment.

BACKGROUND

Cleaning carts are conventionally used to carry cleaning supplies, hang a trash bag, support a mop bucket, and provide storage for various items (e.g., toiletries). Many facilities, such as hospitals, airports, schools, stadiums, etc., have large numbers of carts being regularly and concurrently transported throughout the facility, yet these conventional carts do not clean any area as they are transported. Instead, cleaning staff use sweeping and mopping devices that are separately transported throughout the facility.

In particular, in methods stated as comprising one or more steps or operations it is specifically contemplated that each step comprises what is listed (unless that step includes a limiting term such as “consisting of”), meaning that each step is not intended to exclude, for example, other additives, components, integers or steps that are not listed in the step.

Disclosed herein, in various aspects and with reference to FIG. 1, is a cleaning cart 10 having a body 12 that defines a footprint 14 (corresponding to the space above a floor where the body 12 overlies the floor). For example, the cart can have an outer perimeter, and the outer perimeter can be projected vertically downwardly to the floor to define the footprint 14. The body 12 can define one or more compartments 15, each compartment 15 having a top opening 16. For example, the body can define a rim 17 that receives a bag 18 therein. The body 12 can comprise one or more shelves 20 that can be used for carrying cleaning supplies, toiletries, etc. Optionally, the body 12 can define a front shelf 22 that is configured to receive a mop bucket. The cleaning cart 10 can further comprise a plurality of wheels 24, such as, for example, two front casters 26 that are configured to swivel about vertical axes and two rear wheels 27 that rotate about fixed axes (i.e., the rear wheels 27 do not swivel). The cleaning cart 10 can have a front 30, a rear 32, a longitudinal axis 34 that extends horizontally between the front and the rear of the cart, and a transverse axis 36 that extends perpendicular to the longitudinal axis 34. Optionally, the body 12 can comprise a plurality of vertical supports (e.g., two front and two rear vertical supports) that support the top compartment 15, a bottom shelf 20B and a middle shelf 20A positioned between the bottom shelf and the top compartment. Each of the middle and bottom shelves 20A,B can have a peripheral rim that can retain items on the respective shelf. The front shelf 22 can be positioned forward of the bottom shelf 20B, in front of the two front vertical supports. The rim 17 can be positioned behind the top compartment 15.

Referring to FIG. 2, a sweeping attachment 100 can couple to the body so that a portion of the sweeping attachment engages the floor. For example, the sweeping attachment 100 can attach to an underside 28 of the body 12 as the cart 10 is moved along the floor. Alternatively, in further optional aspects, the sweeping attachment 100 can attach to a front or a back end of the body and extend downwardly therefrom to engage the floor. In some aspects, the sweeping attachment can be coupled to the underside of the body between the front wheels and the rear wheels. The sweeping attachment 100 can have an axis of elongation 102. In some aspects, the axis of elongation can be parallel to, or generally parallel to, the transverse axis 36 of the cleaning cart 10. In further optional aspects, the axis of elongation 102 can be angled with respect to the transverse axis 36 by, for example, 0 to about 60 degrees, about 5 to about 45 degrees, or about 10 to about 30 degrees. In further embodiments, the axis of elongation 102 can be angled with respect to the transverse axis 36 by about five degrees, about ten degrees, about 15 degrees, about 30 degrees, about 45 degrees, or more.

Referring also to FIGS. 5-7, the sweeping attachment 100 can comprise a track 104 that is mounted or otherwise coupled to the underside 28 of the body. The track 104 can couple to the body 12 via screw, rivets, adhesive, or other suitable fasteners. For example, in some aspects, self-tapping screws can extend through the track 104 and into the body 12 of the cart 10. A carriage 106 can slide with respect to the track along an axis of movement 108. The axis of movement 108 can optionally be parallel to the axis of elongation of the sweeping attachment 100. In further aspects, the axis of movement 108 can be perpendicular to the axis of elongation 102 of the sweeping attachment. For example, it is contemplated that the sweeping attachment 100 can slide in the longitudinal dimension of the cart (e.g., from the front or the rear of the cart between the respective front or rear wheels). In further aspects, the axis of movement 108 can be oriented at an acute angle with respect to the axis of elongation 102. Optionally, the track 104 and carriage 106 can be components of a slide 110, such as, for example, a commercially available drawer slide (e.g., Grainger Part No. 4KRV8). The slide 110 can further comprise an intermediate portion 112 that defines a bearing race and facilitates movement between the track 104 and the carriage 106.

The sweeping attachment can comprise a sweeping assembly 120 that is coupled to the carriage 106. The sweeping assembly can comprise a biasing element 128, such as, for example, a flexible, resilient polymer strip (e.g., a strip comprising abrasion-resistant polyurethane rubber), that extends sufficiently downward from the carriage 106 to engage a surface (e.g., floor) beneath the cart. The sweeping assembly can comprise a bracket that couples the biasing element 128 to the carriage 106. For example, the bracket can comprise an L-channel 122 (e.g., a 6063 aluminum, 3/16″ thick, ninety degree angle channel). The L-channel can comprise a first leg 124 that abuts and couples to the carriage 106 and a second leg 126 that extends vertically (or generally vertically) downward therefrom. The biasing element 128 can couple to the second leg 126 of the L-channel 122 and extend downwardly therefrom (optionally, by about one inch) to engage the floor. It is contemplated that it can be beneficial for the biasing element 128 to bend slightly upon engagement with the floor to apply a downward pressure to the floor for providing a sweeping force. Optionally, a strip 130 (e.g., an aluminum strip) can extend across the biasing element 128 on a side opposite the L-channel second leg 126, and fasteners 134 (e.g., bolts and nuts, rivets, etc.) can fasten the biasing element 128 to the L-channel 122. The strip 130 can be, for example, carpet scam binder that can have a slight bend defining a concavity that can face the biasing element so that as the strip 130 is tightened down against the biasing element 128, the strip 130 can deflect. In this way, an edge 132 of the strip 130 can engage the biasing element 128, rather than just at the areas proximate to the fasteners 134.

In some aspects, the sweeping assembly 120 can comprise a front-facing side 142 and a rear-facing side 144. Optionally, the first leg 124 of the L-channel 122 can extend forwardly from the second leg 126, and the biasing element 128 can attach to the front-facing side 142 of the sweeping assembly 120. It is contemplated that mounting the biasing element 128 on the front-facing side of the sweeping assembly can help to maintain the shape of the biasing element.

At least one hook-type reclosable fastener 136 (that is, a hook of a hook and loop fastener) can be positioned on a first side (e.g., the front-facing side 142) of the sweeping assembly. For example, a strip of hook-type fastener can extend along the length of the sweeping assembly. In further aspects, a hook-type fastener can be positioned at a plurality of segments (optionally, small (e.g., optionally, about 1-inch length segments)) spaced along the length of the sweeping assembly. Likewise, a second hook-type fastener 138 can be positioned on a second side (e.g., the rear-facing side 144) of the sweeping assembly 120. The second hook-type faster 138 can similarly be a strip that extends along the length of the sweeping assembly or one or more segments (optionally, small (e.g., optionally, about 1-inch length segments)) spaced along the length of the sweeping assembly. The first and second hook-type reclosable fasteners 136, 138 can attach to the L-channel 122 of the sweeping assembly 120 via a pressure-sensitive adhesive that can be disposed on a side of the fasteners opposite the hook engagement side. In further aspects, the reclosable fasteners 136, 138 can couple to the L-channel 122 of the sweeping assembly 120 via any suitable fasteners.

The sweeping assembly 120 can have a length (along the axis of elongation 102) that is less than or equal to the width of the cart. In further aspects, the sweeping assembly 120 can have a length that is between 85% and 90% of the width of the cart, between 90% and 95% of the width of the cart, between 95% and 100% of the width of the cart, between 1001% and 105% of the width of the cart, or between 90% and 100% of the width of the cart. In further optional aspects, the sweeping assembly 120 can have a length that is greater than 105% of the width of the cart or less than 85% of the width of the cart. In some further aspects, the sweeping assembly 120 can have a length so that the sweeping assembly 120 is entirely, or substantially entirely, within the footprint of the body of the cart. In this way, the sweeping assembly is not a tripping hazard. Thus, for example, for a sweeping assembly 120 that is angled with respect to the transverse axis by forty-five degrees, the sweeping assembly 120 can optionally have a length that is 1.4 times the width of the cart and can still be positioned entirely within the footprint of the cart. More generally, in various optional aspects, it is contemplated that the sweeping assembly 120 can be positioned at any suitable angle that results in the sweeping assembly having an operative dimension measured along the transverse axis that is less than, equal to, or substantially equal to the width of the cart.

A sweeping element 140, such as, for example, a dust sheet, can be connected at a first end to the first hook-type fastener 136, looped around the biasing element 128, and attached to the second hook-type fastener 138. The sweeping element 140 can be an EASY TRAP sweep and dust sheet provided by 3M or any other suitable sweeping element. In some aspects, the sweeping element can be a disposable dust sheet. In further aspects, the dust sheet can be a reusable dust sheet. In still further aspects, the sweeping element can be a reusable attachment, such as a broom that defines a plurality of bristles.

The sweeping assembly 120 can couple to the carriage 106 of the slide 110 via fasteners 146, such as, for example, nuts and bolts, or rivets. The sweeping assembly 120 can be movable, via the slide 110 about and between a first, sweeping position 148 (FIG. 2) that is at least partially, or, optionally, entirely disposed beneath the cleaning cart 10, within the footprint 16 and a second, removal position 150 (FIG. 3) that is at least partially outward of the footprint 16 of the cleaning cart 10. The sweeping attachment 100 can have a distal first end 152 and a proximal second end 154. A grip 156, such as, for example, a hook, handle, and the like, can be coupled to the L-channel 122 at the distal end 152 of the sweeping attachment 100. The grip 156 can enable an operator to pull the sweeping assembly from the sweeping position 148 to the removal position 150.

The sweeping assembly 120 and coupled carriage 106 can be decoupled from the cleaning cart. For example, the slide 110 can comprise a release lever 158 (e.g., a detent) that can release a catch on the carriage 106 to decouple the carriage from the remainder of the slide 110, and, thus, the cleaning cart 10. Such release levers are commonly included on off-the-shelf drawer slides and are not described in detail herein. In this way, the sweeping element 140 can be changed without the difficulty of climbing under the cart and threading the sweeping element 140 between the floor and the biasing element. After removing and replacing the sweeping element 140, the sweeping assembly and carriage 106 can be reattached to the cleaning cart 10 and returned to the sweeping position 148.

Optionally, it is contemplated that the sweeping attachment 100 can be manufactured entirely from off-the-shelf components. Further, the sweeping attachment 100 can be retrofitted on conventional cleaning carts. In positioning the sweeping attachment 100 within the footprint of the cleaning cart, the sweeping attachment can be used without providing a tripping hazard or otherwise affecting the use of the cleaning cart. Further, by positioning the sweeping attachment 100 between the front and rear wheels, the sweeping attachment 100 can be coupled to conventional cleaning carts that do not have space in front of the front wheels or behind the rear wheels to position the sweeping attachment within the footprint of the cleaning cart. In providing the sliding aspect of the sweeping attachment 100, despite positioning the sweeping attachment 100 within the footprint when the sweeping assembly 120 is in the sweeping position 148, the sweeping element 140 can easily be removed and replaced.

Most cleaning service providers have large numbers (e.g., tens) of such conventional cleaning carts that are routinely moved throughout the facilities in which they are being used. However, the conventional cleaning carts are moved throughout the facility without cleaning along the way. Therefore, brooms, mops, or sweepers have to be separately passed over the same floor space across which the carts travel. Although some wheeled powered sweeping/vacuuming apparatuses exist, largely due to cost and storage, cleaning services have a fraction of the number of such wheeled sweeping apparatuses (if any) in comparison to the number of cleaning carts. In contrast, the carts disclosed herein do not include powered sweeping/vacuuming components, and the carts disclosed herein can be easily manufactured using conventional (unpowered) carts and off-the-shelf components.
