DETAILED DESCRIPTION OF THE INVENTION

[0067] Referring to FIGS. 8-11, mounting frame assemblies and components thereof are illustrated for mounting in trucks or vans and that are configured to receive operational units of carpet cleaning systems. In embodiments, a plurality of stainless steel tubing members and/or bars are precut and welded together into a first main mounting frame 100. In embodiments, the rectangular tubing is 1 inch×2 inches and the solid bars are ½ by 2 inches. The frame members are unitary with each other by way of the welding. The linear frame portions 106 have coplanar top surfaces 110. The mounting frame 100 is configured for receiving specific operational units in mounting zones 114, 115, 116 as illustrated by the dashed lines of FIG. 8. The mounting frame 100 is fabricated for securing with threaded fasteners each of the operational units by way of seating and attaching the mounting strips 90 of the operational units to the planar horizontal top surface 110 of the mounting frame 100. The positioning of the threaded fasteners is part of the fabrication process pre installation into the vehicle. In the embodiment depicted, the threaded fasteners 120 comprise threaded studs 120 fixed to the frame portions, such as by welding, and extend upwardly to be received in specific existing holes of the mounting strips of the intended operational unit to be mounted at that location. Alternately, threaded nuts or threaded holes in the respective sites of the frame portions could also be utilized.

[0068] Referring to FIG. 8, in embodiments, the first main mounting frame 100 has forward-rearward linear frame portions 124 and crossing linear frame portions 126, including a forwardmost frame portion 128 and a rearwardmost frame portions 129. The frame portions are planarly arranged providing the planar top surface 110 defining a main datum level for receiving operational units and a planar bottom surface 132 for seating on the floor ribbing. The perimeter frame portions 135 defining a closed geometric figure configured as a polygonal shape when viewed from above defining a polygonal cell. The middle crossing member 133 dividing said figure into two additional polygonal shapes of polygonal cells.

[0069] The distance D1 of zone 1 defined by the width of the frame is essentially equal to the length of the mounting footprint of the intended operational unit to be installed, in this case the vacuum recovery tank unit 74. In embodiments D1 is about 52 inches. The mounting footprint 136 illustrated on FIG. 4 is defined by the outer periphery of the apertured mounting strips 90, in this case, the mounting flanges. The second zone 115 is configured for the hose reel and storage tank unit 80 which has a mounting footprint 137 which is greater than the length of the mounting footprint of the vacuum recovery tank unit accounting for the jog 139 in the port side of the frame assembly 100. The width of the mounting zone D2 is about 54 ½ inches which equates to the length of the reel and tank operational unit 80. Due to the significant weight of the tank when filled with liquid, a tank load carrying crossing member 141 is positioned directly below and centralized to the tank for supporting said weight. The third zone is for receiving an elevated auxiliary tank unit discussed below.

[0070] Referring to FIG. 9, an additional mounting frame assembly configured as a mounting frame forward extension 140 is illustrated and has two forwardly extending beam frame portions 142, a forward crossing frame portion 144, a rearward mounting crossing frame portion 145, a bridging seating frame portion 147, and feet 149. This frame assembly is configures to be attached to the forwardmost crossing frame portion 128 of a main mounting frame 100, such as is shown in FIG. 8. The forward extension is configured to receive a blower pump unit 70 and to position the blower pump unit in-between the passenger and driver seats. The forward extension 140 is configure to raise the datum level of the blower pump unit several inches above datum level defined by the top surface of the first main mounting frame 100. The inventor has found that this provides more optimal positioning with transferring power by way of the driveshaft 68 and further elevates the engine from the floor and eliminates the need for mounting holes in proximity to the van transmission positioned below this location. The weight of the blower pump assembly distributed to the van floor by the forwardmost crossing frame portion 128 and the two feet. The forward extension 140 may be bolted on or welded on to the

[0071] Referring to FIG. 10A, an elevating tank mounting frame 158 is illustrated for mounting the prior art tank 88 of FIG. 5. In embodiments, the frame is comprised primarily of 2 inch×2 inch stainless steel tubing sections. Four posts 160 and four horizontal frame portions 164 of the tubing are welded together on a 1 inch×2 inch solid stainless steel bars forming a base 168. Apertures 170 are added to the base. The mounting footprint 174 of the auxiliary tank corresponding to the upwardly facing planar mounting surfaces 178 of the frame 158. The prior art tank of FIG. 7 may then be mounted on the frame 158 as illustrated in FIG. 10B by way of brackets 162. The 1 inch by 2 inch base with apertures 163 then define a mounting strip 90 and the assembled frame and tank is an operational unit, specifically an auxiliary tank unit 180, for the carpet cleaning system that may be added to the main mounting frame 100 along with the other operational units.

[0072] In embodiments, the main mounting frame 100 and frame portions thereof may comprise 1″×2″ rectangular tubes. In embodiments, the 2″ side of the rectangular tubes may comprise the top surface 110. In embodiments, the 1″ side of the rectangular tubes may comprise the top surface 152 of the frame forward extension 140. In embodiments, the main mounting frame portion 100 and beams thereof may comprise 2″×2″ square tubes. In embodiments, the main frame portion 100 and beams thereof may comprise a combination of 1″×2″ rectangular tubes and 2″×2″ square tubes. In embodiments, the rectangular and square tubes and bars may be # 304 stainless steel. In embodiments, certain frame portions may comprise C channel or U channels. In such embodiments, the frame portions can have apertures aligned with the holes of the apertured mounting strips of the operational units, allowing a bolt to extend through the aligned apertures and a nut can be attached to the bolt. The C channel or U channels may be stainless steel. In other embodiments the frame may be attached to the van floor by welding such that there no need to penetrate the van floor. Brackets may be welded to the floor that are then removably attachable to the mounting frame (not show).

[0073] Referring to FIG. 11, a mounting frame assembly 200 is illustrated and includes the main mounting frame 100, the mounting frame forward extension 140 attached to the forward most crossing member 128, and the elevating tank mounting frame 158 is mounted on the rearward end portion 204 of the main frame. Threaded studs 120 are positioned to be aligned with the apertures of the mounting strips, such as flanges, of the operational units. The specific units may be such as is portrayed in FIGS. 2A-5.

[0074] Referring to FIGS. 12 and 13, in embodiments, the mounting frame assembly 200, at least the main frame and forward extension would typically first be mounted in the van on the cargo box floor before the operational units are installed thereon. The frame may be inserted through the rear access door and positioned as depicted in FIG. 12 with the forward extension 140 that receives the blower pump unit positioned between the passenger and driver's seat 34, 36. A suitable attachment method of the frame assembly 200 to the van ribbed floor is illustrated by FIG. 13. A forward-rearward frame portion 124 may be positioned over a raised region 210 of the ribbed floor 48 with ribbing 49 such that the planar lower facing surface 214 of the rectangular tubing contacts an upwardly facing surface 216 of the ribbed floor. A hole 220 may be drilled through the rectangular tubing and through the ribbed floor. A plate 224 with a central hole 226 of sufficient size to engage a plurality of the downward facing ribs 218 is positioned below the drilled hole. A plate with a diameter or width of 8 inches is suitable. A bolt 230 is inserted through the aligned holes and is secured with a washer 231 and nut 232. Sealer such as silicon 233 can be used to seal the hole and cover the exposed metal of the floor due to the drilling of the hole.

[0075] The above attachment of the mounting frame can be compared with the prior art method of FIG. 1C where due to the multiplicity of holes needed to attach each individual operational unit, the hole position cannot be controlled or adequately selected resulting in less than ideal connections. Suitably, the main frame 100 may have attachments 237 with four bolt and nut combinations approximately at the corners of the main frame compared to the multiplicity, typically 20 or more, needed for the conventional attachment of the individual operational units to the floor.

[0076] Once the frame assembly is installed, the operational units, such as portrayed in FIGS. 2A to 5, the blower pump unit 70, the vacuum recovery tank unit 74, the hose and liquid storage tank unit 80, may be installed. In embodiments, the units are carried into the cargo area, are positioned over the zone where the unit is to be installed and is lowered such that apertures in the mounting strip, are aligned with the upwardly projecting threaded studs, the unit is seated on the upper surface of the mounting frame with the stud extending through the aperture in the respective mounting strip, washers and nuts 241 are attached to the studs securing the unit in place. See FIG. 14. The planar mounting surface 243 of the frame portion receives the lower planar mounting surface 245 of the apertured mounting strip 90 for a robust connection. Compare this to the issues illustrated in the conventional attachment of FIG. 1C.

[0077] Referring to FIGS. 15, 16, and 17, the operational units are secured to the mounting frame assembly 200. FIG. 17 shows detail of the blower pump unit mount not visible from the view of FIG. 16. Appropriate wiring and connections are made and the van with the carpet cleaning system 260 is complete and ready for deployment. The operational units may be readily accessed, serviced and removed through either the cargo van side door or rear access door.

[0078] In embodiments, the blower pump unit 70 may be mounted on the forward extension 140 prior to positioning the mounting frame assembly 200 in the vehicle. An example of a blower pump unit as depicted is available from Hydramaster Corporation, Mukilteo, Wash. In embodiments, installing and securing the mounting frame assembly 200 and the blower pump unit may take about 1 hour.

[0079] In contrast, installation of a blower assembly using conventional methods requires locating the proper place for the blower assembly on vehicle floor; drilling four holes in the vehicle floor and mounting two brackets, typically ¼ inch steel brackets; mounting the blower assembly on top of two brackets and aligning the driveshaft using an engine hoist; and bolting the top blower bracket to the installed brackets. The conventional methods typically take about four hours and require two people.

[0080] An example of a hose and tank assembly 80 is Hydra-Master's CDS Hydra Cradle tank. In embodiments, installing and securing a hose and tank unit may take one person about 15 minutes.

[0081] In contrast, installation of a hose and tank assembly using conventional methods requires: sliding the tank into place and measuring and marking distances for holes; drilling eight individual holes in the floor of the vehicle for mounting; bolting down and securing the tank in place using small tabs and bolts usually provided in a kit. Conventional methods typically takes about 1-2.5 hours and requires two people.

[0082] An example of a vacuum recovery tank unit 74 is available from Hydramaster Corporation, Mukilteo, Wash. In embodiments, installing and securing a recovery tank unit as described herein may take two people to move the tank and one to install and about 15 minutes.

[0083] In contrast, installation of the vacuum recovery tank unit 74 using conventional methods requires: sliding the tank in the side door of the vehicle; measuring and marking five holes to be drilled in vehicle floor; drilling and installing bolts and brace provided in an installation kit. Installation typically requires about 1-2 hours and requires two people to install.

[0084] In embodiments, installing and securing the auxiliary tank unit 180 may require two people and take about 15 minutes.

[0085] In contrast, installation of a water tank using conventional methods requires: mounting the tank on a frame or directly on the floor of the vehicle; placing the tank in the vehicle and marking positions for six mounting holes for drilling; removing the tank and drilling the six holes; reinstalling the tank; bolting the tank down with the six bolts in the vehicle floor; and installing a back support bracket for the tank to minimize the weight tipping it over. Installation typically requires 2 people and takes about 2-3 hours.

[0086] With the frame assembly described herein, weight is evenly distributed across vehicle interior. Whereas, for conventional installations, there is no weight distribution for full water tanks. Each tank of the various assemblies presses on the thin floor of the vehicle. The many bolts required to secure the individual assemblies serve to provide further uneven pressure on the floor of the vehicle.

[0087] With the frame assembly described herein, there are no holes drilled over the transmission tunnel of the vehicle for the blower assembly mount, which can weigh about 400 lbs, creating a weak spot for rust.

[0088] With the frame assembly described herein, there is minimal area for water to accumulate and cause rust or damage to vehicle and equipment. Whereas, conventional installations allow for multiple locations for water to sit and rust the vehicle from inside out. Over time this can pose hazards from rust holes in floor of vehicle.

[0089] With the frame assembly described herein, the total install time, start to finish, may be one to two 2 days with one dedicated technician and one helping for less than 1 hour. Whereas, for conventional installations, the average time to install a full working system is about one week with two dedicated technicians.

[0090] With the frame assembly described herein, installation of a DDTCS is faster, requires less man-power, decreases damage to the vehicle and materials and increases technician safety.
