Description

FIELD OF INVENTION

The present invention relates to application of stripping solutions to floors and base boards and/or floor edges and more particularly relates to a riding floor and edge stripper applicator.

SUMMARY OF INVENTION

Currently floor stripping solutions are applied using mops and/or walk behind applicators similar to the ones depicted in U.S. Pat. No. 3,457,015 titled: MOBILE WAX APPLICATOR issued on Jul. 27, 1969 to James Taber and/or the device described in U.S. Pat. No. 4,152,084 titled: PORTABLE FLOOR FINISH APPLICATOR issued May 1, 1979 to Joseph E. Melton and Glen G. Lorch and/or the device as described in U.S. Pat. No. 6,017,163 titled: FLOOR FINISH DISTRIBUTION APPARATUS issued Jan. 25, 2000 to Keppers et al and/or variations of these types of equipment.

Powered and/or riding Floor Finishing Machines as described in U.S. Pat. No. 6,023,813 titled: POWERED FLOOR SCRUBBER AND BUFFER issued Feb. 15, 2002 to David Thatcher et al are limited to floors which either scrub, apply and/or polish floor services, however to date there has been no successful power operated stripper applicator brought to the market due to the inherent difficulties with applying stripper to floors.

The difficulty with the application of stripper is that once the chemical solution is applied to the floor, the floors become extremely slick and personnel who are applying the solution manually find it very difficult, if not impossible to walk over the surface. Machines that have attempted to apply stripper to floors, find it difficult and dangerous to move the equipment over the floors once the stripper has been applied, because of the extremely slick surface conditions.

The nature of floor stripping requires that the floor continually be maintained in a moist or wet condition in order for the stripper to actively remove the surface finish. Therefore, it is necessary to continually reapply solution and/or liquid over the portions of the floor and/or edges that have dried, in order to reactivate the solution to the point where the stripper is able to complete the chemical reaction and remove the floor stripper. Therefore, in order for the stripper to completely remove the existing floor finish from the floor end or edge, it is always necessary to make additional passes over the dry areas of the floor to add additional stripper to the floor to complete the stripping process until the finish has been completely emulsified

A person skilled in the art will know how slippery the floor surface is once stripper has been applied and those working with stripping solutions find it difficult and dangerous to walk over or take any kind of machine over surfaces where stripper has already been applied.

Therefore, it is desirable to have a machine which the personnel do not need to walk over floor surfaces having stripper applied thereon and has the capability of making multiple passes over the floor surface to be stripped and add additional floor stripper as required as the floor surface dries out. It is also desirable to have a machine which can apply stripper to the floor edges, or baseboard portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present riding floor and edge stripper applicator shown generally as 100 is a riding floor and edge stripper applicator which includes the following components namely, forward frame 110, boom 112, connecting forward frame 110 with rear frame 116 at pivot 114. In this example the steering is accomplished by pivoting the forward frame 110 relative to the rear frame 116. Other steering mechanisms are possible including a steer able drive wheel 120 for example or driving front wheels 128 a differential speeds. The riding floor and edge stripper applicator 100 is not limited to the drive mechanism shown.

Seat 118, drive wheel 120, drive pulley 122, drive motor 142 and power pack 144 are all connected to rear frame 116. The figures show a motorized drive however the unit could also be powered by manual power such as a pedal drive system actuated by the users feet similar to a bicycle drive system. A manual drive may be a direct pedal drive without a chain directly to drive wheel 120 for example.

Central mop 130 is attached to forward frame 110 and swing mop 132 is attached to central mop 130 and includes an edge applicator 134 mounted on an edge end 251 of swinging mop 132. Edge applicator receives stripper fluid from supply conduits 160 and applies the fluid to the wall edge or baseboard when the edge applicator 134 makes contact with the vertical portion of the wall edge or baseboard.

Central mop 130 includes central mop frame 202, having a pivot cylinder 204 attached thereon and connected to swinging mop frame 206, such that swinging mop frame 206 pivots, at pivot point 208 with respect to central mop 202. Front wheels 128 as well as drive wheel 120 include tire covers 150 which are removable covers providing grip on slick surfaces, such as when stripper is applied to a floor.

Auxiliary wheels 140 are also attached to forward frame 110 and are used to transport the riding floor and edge stripper applicator 100 from one job site to another, thereby avoiding contact of front wheels 128 with dirty surfaces when moving from one job site to another.

Riding floor and edge stripper applicator 100 includes a main tank 136 which normally would house a stripping solution as well as secondary tank 138 which includes a special stripping solution which is supplied to edge applicator 134. Solutions from main tank 136 and secondary tank 138 are delivered to central mop 130, swinging mop 132 and edge applicator 134 via supply conduits 160 which communicates stripping fluids to the desired location.

Riding floor and edge stripper applicator 100 also includes a steering handle 170 which houses thereon operator controls 180 for controlling fluid flow to the central mop 130, the swinging mop 132, the edge applicator 134 as well as for pivoting the forward frame 110 for turning riding floor and edge stripper applicator 100 left and right.

Swing mop control pedals 126 are provided in order to activate pivot cylinder 204 in order to either extend swinging mop 132 or retracting swinging mop 132. Further controls are provided for engaging and disengaging drive wheel 120 and providing for forward and reverse movement of riding floor and edge stripper applicator 100.

Referring now to FIGS. 6, 7 and 8 showing central mop 130 pivotally connected to swinging mop 132, wherein in FIG. 6 it shows the swinging mop portion in the fully retracted position in dashed line in the partially extended in solid lines and in FIG. 7 it shows swinging mop 132 in the fully extended position in solid lines and in a hyper extended position in dashed lines in FIG. 7.

Referring now to FIG. 8, swing mop 132 includes a flexible tip portion 161 which has a certain amount of resilience or flexibility which allows it to flex and/or pivot independently of swinging mop 132. Flexible tip portion 161 is normally resiliently biased in unfolded position 165 and moveable to folded position 163 when the tip strikes a rigid object. Flexible tip 161 is shown in the unfolded position 165 in solid lines and in a folded position 163 in dashed lines, and folds when for example flexible tip 163 makes contact with a floor edge vertical surface such as a base board.

A person skilled in the art can see by using various controls on the riding floor and edge stripper applicator, one is able to extend swinging mop 132 from the fully retracted position 281 shown in dashed lines in FIG. 6 to a hyper extended position 283 shown in dashed lines in FIG. 7 or to a partially extended position 285 as shown in solid lines in FIG. 6. In FIG. 7 swinging mop 132 is shown in an extended position 287. In this way, one can maneuver swinging mop 132 around various obstacles by either extending or retracting swing mop portion 132, relative to central mop 130. In addition, when flexible tip 161 encounters the edge of a floor such as a base board, for example flexible tip 161 will flex as shown in FIG. 8 in dashed lines to a folded position 163, thereby maintaining good contact with a floor edge vertical surface such as a baseboard (not shown).

Referring now to FIGS. 11, 12, 13 and 14 which shows more details of front wheels 128 showing tire covers 150 thereon. Note also that drive wheel 120 in similar fashion also has a tire cover 150 thereon. Therefore FIGS. 11 through 14 inclusively depict not only front wheels 128, but also drive wheel 120 in regard to the cover components shown in these diagrams.

Tire covers 150 include attachment points 153 which are fastened together using a tightening cord 151 for holding tire cover 150 around the out diameter of tread 155 of wheel rim 157. Tire cover 150 is made of an abrasive material which is able to penetrate through the floor stripper and/or for that matter any emulsified floor finish and be able to gain traction onto the floor being stripped, even though there is a combination of floor stripper and emulsified floor finish lying wet on the floor. In this manner, riding floor and edge stripper applicator 100 will be able to gain traction and move comfortably without sliding over a wet floor surface having a floor stripper applied to it and/or having floor stripper as well as emulsified floor finish laying on the floor.

Preferably tire covers 150 are removable as depicted in FIGS. 11 through 14, however, it may be possible to manufacture front wheels 128 and drive wheel 20 with an abrasive material impregnated into the tire tread 155, wherein there is not a removable tire cover 150. The abrasive material used for the tire covers 150 or to be incorporated directly into the tire tread can for example be a waterproof abrasive such as scrubbing pads or an abrasive as applied to waterproof sand papers.

Preferably tire cover 150 is removable, such that when the tire covers 150 become contaminated with dirt and/or wear out, they can be easily replaced by detaching tightening cords 151 from attachment points 153, thereby allowing tire cover 150 to be removed.

Stripper as used herein means domestic and industrial floor strippers applied to floor surfaces and used to chemically remove existing floor finishes.
