Definitions

  • ABSTRACT A battery-powered three-wheeled floor scrubber vehicle having a single steerable front drive wheel and a frameless body structure consisting of a series of interconnected tank members and a pair of hydraulically controlled floor scrubbing brushes and squeegee arrangement mounted forwardly of the front steerable drive wheel.
  • a floor-scrubbing apparatus including a frameless vehicle having a single front steerable hydraulically driven drive wheel, a pair of hydraulically driven rotatable floor scrubbing brushes and a comer squeegee mounted forwardly of the steerable front drive wheel, with the entire structure hydraulically controlled for simultaneous or independent movement into and out of floor-scrubbing position.
  • a master hydraulic cylinder is utilized to control the positioning and operation of the scrubbing brushes and their supporting structure for movement into and out of operating position, with a secondary hydraulic cylinder utilized to position the comer squeegee and its supporting structure relative to the brush-supporting structure.
  • These hydraulic cylinders, as well as the front drive wheel, are all connected to and operated by a batterypowered hydraulic pump unit and independently controlled by the operator of the vehicle.
  • FIG. 1 is a perspective view of the floor-scrubbing apparatus
  • FIG. 2 is a perspective view of the front brush and squeegee structure associated with the apparatus
  • FIG. 3 is a perspective view of the front corner squeegee supporting structure
  • FIG. 4 is a fragmentary sectional view of the front wheel drive arrangement
  • FIG. 5 is a side elevational view of the apparatus showing certain parts thereof in exploded relationship
  • FIG. 6 is a fragmentary detail sectional view of the corner squeegee support and pivoting structure.
  • the apparatus of this invention as shown in FIGS. 1 and 5 is of a frameless structure and, as such, consists of a series of connected structures.
  • the scrubbing vehicle 10 includes a solution tank 1 1 having welded to one end a perpendicularly disposed vertically extending front instrument panel 12.
  • a wheel compartment 13 is welded to the opposite end wall of the solution tank 11 and cooperates with such tank to removably support by means of interrelating clips 14 and the like a battery compartment 15 which in turn removably supports a recovery tank 16.
  • axle 17 Adapted to extend through the wheel compartment 13 and be connected theretoby any suitable means, is an axle 17 which has mounted thereon freely rotatable rear wheels 18.
  • a supporting shelf 19 that has journalled through a suitable bushing 20 carried thereby the supporting and steering post 21 of the hydraulically driven steerable front wheel 22.
  • the steering post 21 is connnected to an inverted L-shaped wheel bearing bracket 23, which provides a suitable wheel bearing 24 into which is journalled the axle (not shown) of the front wheel 25.
  • the front wheel 25 has formed in one side thereof a circular recess 26 into which projects a medial leg 27 and depending arm 28 of an offset mounting bracket 29.
  • the upper arm 30 of the bracket 29 is connected by means of bolts 31 to one side wall 32 of the base 33 of the inverted L-shaped bracket 23.
  • the motor 34 includes a pair of conduit connectors 35 and 36 which in turn are connected respectively to conduits 37 and 38 which in turn are connected to a hydraulic pump and reservoir (not shown) but well known in the art.
  • the hydraulic fluid forced under pressure through the conduits 37 and 38 effects operation of the hydraulic motor 34 to drive the wheel 25.
  • a guide structure 39 which consists of a plurality of semicircular discs 40, 41 and 42 which are connected in spaced parallel relation by suitable connectors 43 which also function to form separate compartments 44 and 45 between the discs.
  • the discs 40, 41 and 42 are adapted to be disposed in a horizontal plane and to extend circumferentially about the inverted base 33 of the L-shaped bracket 23.
  • the conduit 37 is disposed within the compartment 44 formed between the discs and 41, while the conduit 38 is disposed within the compartment formed between the discs 41 and 42.
  • the structure 39 turn, maintaining the conduits 37 and 38 in a separated organized relation with respect to each other.
  • FIG. 2 there is shown the arrangement for supporting the rotatable scrub brushes 46 and 47, as well as a front comer squeegee 48.
  • Mounted on the free ends of the wheel axle 17 are the corresponding ends 49 and 50 of supporting bars 51 and 52.
  • a plate 53 Welded across the bars 51 and 52 adjacent their free ends, is a plate 53 which in turn provides mounts 56 and 57 associated with the rotatable scrubbing brushes 46 and 47.
  • the bar 51 is of a length shorter than that of the bar 52 so as to present a diagonally disposed front bumper 58 which is connected not only to the free ends of the bars 51 and 52, but also to their respective outer wall surfaces intermediate their ends, as shown.
  • Carried by the long side reach 59 of the bumper 58 is a top plate 60 of a squeegee-supporting structure 61.
  • the squeegee-supporting structure 61 comprises the top plate 60, which in turn is connected by a pair of pivotal links 62 and 63 to a bottom plate 64, which in turn supports the front corner squeegee 48.
  • the links 62 and 63 have their ends pivotally connected to pivot pins 66 and 67, which in turn are journalled through confronting mounting blocks 68 and 69 provided by opposite faces of the top and bottom plates 60 and 64.
  • the top and bottom plates 60 and 64 through the linkage connection constitutes a parallelogram which operates under the influence of the movement of a piston 70 of a hydraulic cylinder 71.
  • the hydraulic cylinder 71 is fixedly connected to a lug 72, which in turn is connected to the bumper 58.
  • the free end of the piston 70 of the cylinder 71 is connected to an elongated portion of pivot pin 67, which connects the mounting block 69 of the bottom plate 64 to the link 63.
  • a coil spring 73 extends between the top plate 60 and the corner squeegee 48 and normally functions to maintain the parallelogram formed by the plates 60 and 64 in its collapsed or closed position. In such a position the squeegee 65 is raised into position where it will be out of contact with the floor to be scrubbed.
  • the complete supporting structure heretofore described for the brushes 46 and 47 and the comer squeegee 48 may be hydraulically pivoted relative to the axle 17 into and out of operative position through the connection of the free end of a piston 74 of a hydraulic cylinder 75.
  • the free end of the piston 74 is pivotally connected as at 76 to the plate 53 while the opposite end of the cylinder 75 is connected to a suitable support provided by the instrument panel 12.
  • the cylinder 75 When the cylinder 75 is activated, it expels or withdraws the piston 74, effecting the pivotal raising and lowering of the cleaning structure, as desired.
  • a battery-powered hydraulically driven threewheeled floor-scrubbing personnel-carrying vehicle wherein the improvement comprises i a. a steerable hydraulically driven front wheel and a pair of freely rotatable rear wheels journalled on a rear axle,
  • a battery-powered hydraulically driven threewheeled floor-scrubbing personnel-carrying vehicle as defined by claim 1, wherein said means movably connecting said corner squeegee to said supporting structure comprises a movable parallelogram arrangement between said squeegee and said supporting structure for independently moving said comer squeegee member relative to said supporting structure through a substantially vertical plane.
  • a battery-powered hydraulically driven threewheeled floor-scrubbing personnel-carrying vehicle as defined by claim 5, wherein said means movably connecting said corner squeegee to said supporting structure comprises a movable parallelogram arrangement between said squeegee and said supporting structure for independently moving said corner squeegee member relative to said supporting structure through a substantially vertical plane.
