Also disclosed is a service desk that can be employed with the moveable service cart or independently thereof. ## Claims ### Claim 1 A service desk assembly comprising: a planar body having an outwardly oriented face and an opposed inwardly oriented face, the planar body having an upper edge and an opposed lower edge, the opposed lower edge having a lower ledge member contiguously joined to the planar body at a location proximate to the opposed lower edge and projecting angularly outward from the outwardly oriented face, the planar body having a planar body length PL; a rear support having a first end and an opposed second end, the first end of the rear support pivotally connected to the upper edge of the of the planar body, the rear support having length RL, wherein RL is equal to or less than PL; and at least one central folding strut having a first end and an opposed second end, the first end of the central folding strut foldably mounted on either the rear support or the opposed inwardly oriented face of the planar body at a central location, the opposed second end having at least one engagement member defined thereon, the at least one engagement member configured to releasably contact the opposed inwardly oriented face of the planar body when the first end of the central folding strut is mounted on the rear support or the central folding strut when the at least one central folding strut is foldably mounted on the opposed inwardly oriented face. ### Claim 2 (depends on 1) The service desk assembly of claim 1 wherein the opposed lower ledge member of the planar body projects outward at a right angle to the outwardly oriented face. ### Claim 3 (depends on 2) The service desk assembly of claim 2 wherein the central folding strut further comprises a hinge, the hinge connected to the central folding strut at a location proximate to the first end, the central folding strut further comprising an angular projection member the angular projection member defining an angle between the angular projection member and the central folding strut that is between 10 degrees and 85 degrees. ### Claim 4 (depends on 3) The service desk assembly of claim 3 wherein the hinge associated with the central folding strut is connected to the opposed inwardly oriented face of the planar body at a central location central to the opposed inwardly oriented face. ### Claim 5 (depends on 4) The service desk assembly of claim 4 wherein the planar body has a width PW, the rear support has a width RW and the central folding strut has a width CW, wherein RW is equal to or greater than PW. ### Claim 6 (depends on 4) The service desk assembly of claim 4 wherein the planar body has a width PW, the rear support has a width RW and the central folding strut has a width CW, wherein CW is equal to or less than PW. ### Claim 7 (depends on 1) The service desk assembly of claim 1 further comprising at least one desk assembly elongate hook member, the at least one desk assembly elongate hook member projecting upward from a location proximate to the connection between the planar body and the rear support. ### Claim 8 (depends on 7) The service desk assembly of claim 7 wherein the desk assembly elongate hook member is contiguous to the upper edge of the first end of the rear support. ### Claim 9 (depends on 1) The service desk assembly of claim 1 further comprising central hinge member, the central hinge member configured to provide pivotal connection between the planar body and the rear support, the central hinge member having a width HW that is less than or equal to PW. ### Claim 10 (depends on 1) The service desk assembly of claim 1 wherein the planar body, rear support and at least one central folding strut are constructed from stainless steel. ### Claim 11 (depends on 1) A moveable service cart for transporting cleaning tools and equipment, the moveable service cart comprising: a base member, the base member having a base member length and a base member width wherein the base member width is less than the base member length, the base member having an upwardly oriented face and a downwardly oriented face when the moveable service cart is in the use position; at least two wheel mechanisms connected to the base member and projecting downward from the downwardly oriented face; a central storage housing connected to the base member, the central storage housing having a central storage housing width that is equal to or less that the base member width and a central storage housing length that is less than the base member length and a central storage housing height that is equal to or greater than width of the base member, the central storage housing defining a central storage cavity and having a top face parallel to the base member, a rear wall and opposed side walls and at least one access door, the at least one access door opposed to the rear wall and moveable between a closed position and at least one open position, the at least one access door having an inner face and an opposed outer face, wherein the central storage housing has at least one equipment receptacle defined in the at least one access door projecting into the central storage cavity when the at least one access door is in a closed position and at least one equipment receptacle defined in the central storage cavity; and the service desk assembly of claim 1. ### Claim 12 (depends on 11) The moveable service cart of claim 11 for transporting cleaning tools further comprising: at least one fluid charging station defined on the top face of the central storage housing. ### Claim 13 (depends on 11) The moveable service cart of claim 11 further comprising at least one waster receptacle mounting unit, the waste receptacle mounting unit pivotally extendable from a location defined proximate to the top face of the central storage housing and pivotal between a use position projecting outward from one of the opposed side walls of the central storage housing to a storage position location overlying the top face of the central storage housing. ### Claim 14 (depends on 13) The moveable service cart of claim 13 wherein the base member is comprised of a first segment and a second segment, the second segment moveable relative to the first segment, wherein the central storage housing is connected to the first segment of the base member and the second segment of the base member pivots laterally between a first use position in which the second segment extends outward from the first segment and a second position in which a distal end of the second segment is proximate to the opposed side walls of the central storage housing. ### Claim 15 (depends on 14) The moveable service cart of claim 14 wherein the second segment of the base member includes at least one second segment wheel mechanism. ### Claim 16 (depends on 15) The moveable service cart of claim 15 further comprising at least one mop bucket removably positionable on the second segment of the base member. ### Claim 17 (depends on 11) The moveable service cart of claim 11 further comprising at least one retaining lip located along at least a portion of a periphery defined on the top face of the central storage housing and extending perpendicularly upward therefrom. ### Claim 18 (depends on 11) The moveable service cart of claim 11 further comprising a service desk removably connected to the central storage housing, the service desk having a central planar member, the service desk pivotally mounted relative to the central storage housing such that the central planar member is parallel to the opposed side walls of the central storage housing in a non-use position and projects angularly from the central storage housing when in a use position. ### Claim 19 (depends on 11) The moveable service cart of claim 11 wherein the at least one access door of the central storage housing comprises at least one lower equipment receptacle and at least one upper equipment receptacle, the at least one lower equipment receptacle comprising side members connected to the inner face of the at least one access door, a lower floor member connected to the inner face of the access door and to the side members, the side members and floor member projecting outward therefrom and an outer face plate connected to the side members at a spaced distance from the inner face of the at least one access door, the opposed side walls and face plate defining a lower receptacle inner cavity, the equipment lower receptacle having a side aperture defined in the outer face plate and at least one upper aperture. ### Claim 20 (depends on 19) The moveable service cart of claim 19 wherein the at least one lower equipment receptacle is composed of three rectangular members positioned in spaced relationship with one another.
