Description
- This application claims the benefit of U.S. Patent Application Ser. No. 61/276,221 filed on Sep. 9, 2009, which is incorporated by reference in its entirety.
- The present invention relates to a brush and vacuum assembly and its method of use. More particularly, the invention relates to a brush and vacuum assembly and method of use with floor cleaning equipment, such as a floor scrubber.
- The present invention is an improvement over known floor cleaning equipment, such as floor scrubbers. Most floor scrubbers have a water supply, a cleaning solution and outlets that apply the water and/or cleaning solution onto a floor. A set of rotary brushes works the cleaning solution into the floor to lift dirt and debris from the floor and scrub the floor clean. A squeegee and water suction device may be located at the rear of the machine to collect excess water and cleaning solution from the floor.
- Those skilled in the art know that floor maintenance also typically requires vacuuming, usually before the scrubbing step. Vacuuming requires additional equipment, time and labor. Thus, it is known to associate a vacuum apparatus with a floor scrubber to accomplish both steps at once.
- However, known equipment that combines a floor scrubber with a vacuum apparatus has proven to be difficult to use. More particularly, known devices locate the debris bins, which are bins that collect dirt and debris from the vacuum apparatus, in very difficult to reach places. The present invention overcomes the disadvantages of the prior art designs by locating a debris bin in a convenient location that is easily accessible.
- The present invention is directed toward a brush and vacuum assembly and a method of its use. The assembly has a debris box selectively located within a debris box housing. At least one arm extends downwardly from a deck supporting at least one brush motor. At least one pin extends through the at least one arm for selective engagement with the debris box housing. The debris box is located in an easy to reach area that facilitates its removal and replacement.
- The above, as well as other advantages of the present invention, will become readily apparent to those skilled in the art from the following detailed description when considered in the light of the accompanying drawings in which:
-
FIG. 1 is a side view of one embodiment of a brush and vacuum assembly depicting a deck, a debris box housing and a debris box in a lowered position; -
FIG. 2 is a side view of the assembly ofFIG. 1 with the deck in a raised position and the debris box housing and debris box in a first, raised position and the debris box housing and the debris box in a second, alternative lowered position in dashed lines; -
FIG. 3 is a perspective view of the deck in a raised position and the debris box and debris box housing in a lowered position; -
FIG. 4 is a partial, front view of a pin of the present invention; -
FIG. 5 is a side view of the brush and vacuum assembly with a floor scrubber; -
FIG. 6 is a top view partially depicting the assembly and floor scrubber with the cover of the assembly being removed; -
FIG. 7 is a side view of another embodiment of the assembly depicting the deck, the debris box housing and the debris box in a lowered position; -
FIG. 8 is a side view of the assembly ofFIG. 7 with the deck in a raised position. - It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions, directions or other physical characteristics relating to the embodiments disclosed are not to be considered as limiting, unless the claims expressly state otherwise.
- Turning now to
FIG. 1 , one embodiment of a brush andvacuum assembly 10 and part of afloor scrubber 12 is depicted. Theassembly 10 comprises adeck 14. Thedeck 14 is connected to thefloor scrubber 12. More particularly, arear portion 16 of thedeck 14 is connected to afront portion 18 of thefloor scrubber 12. The connection may be made via one ormore hinges 20. Thehinges 20 are also depicted inFIGS. 2 , 5 and 6. - A
first part 22 of ahinge 20 is connected to therear portion 16 of thedeck 14. - The
second part 24 of thehinge 20 is connected to thefront portion 18 of thescrubber 12. This arrangement permits thedeck 14 to pivot upwardly and downwardly with respect to thescrubber 12. Ahinge axis 26 is created between thefirst part 22 of thehinge 20 and thesecond part 24 of thehinge 20. - An
actuator mount 28 may also be located at thefront portion 18 of thescrubber 12. Theactuator mount 28 may have anupper portion 30 and alower portion 32. Thelower portion 32 is preferably connected to thefront portion 18 of thescrubber 12. Theupper portion 30 is adapted to pivotally mount anactuator shaft 34 therewith. More particularly, anactuator shaft 34 may be pivotally mounted to theupper portion 30 of themount 28. - The
actuator shaft 34 selectively extends into ashaft housing 36. Theshaft housing 36 is pivotally mounted to thedeck 14. Preferably, adeck actuator mount 38 is provided that pivotally connects theshaft housing 36 with thedeck 14, as shown inFIG. 6 . Thedeck actuator mount 38 may be located at acentral portion 40 of thedeck 14, but other locations are permissible. - While a
single actuator shaft 34 is depicted, it is permissible to include additional actuators. The additional actuators may be spaced from one another along thescrubber 12 and thedeck 14. The actuators may be identical to one another or they may be or various sizes and capacities. - Regardless of the number or size of the
actuator shaft 34, theactuator shaft 34 provides for a controlled raising and lowering of thedeck 14. More particularly, thedeck 14 and its associated components, which are described below, can be heavy. It is preferred that thedeck 14 be raised and lowered with at least the assistance of theactuator shaft 34 so that it is slowly moved to permit workers time to remove themselves from the movingdeck 14, to ensure the machine is not damaged by a droppeddeck 14 and to ensure that the machine does not damage the floor. - As best seen in
FIG. 6 , at least onebrush motor 42 is mounted on anupper side 44 of thedeck 14. Preferably, twobrush motors 42 are located on afirst side 46 and asecond side 48 of theupper side 44 of thedeck 14. Thebrush motors 42 are drivingly connected to twobrushes 50 located beneath alower side 52 of thedeck 14. Thebrush motors 42 are connected to a source of electrical energy, such as a battery (not shown) located on thescrubber 12. It may be readily appreciated that greater orfewer brush motors 42 and brushes 50 may be used and that they may be located anywhere on or in thedeck 14. - The
brushes 50 havelong bristles 54 designed to contact the floor. When turned by thebrush motors 42, thebristles 54 move in a circular pattern and collect dirt and debris from the floor. Thebristles 54 deposit collected dirt and debris onto aramp 56. In the depicted embodiment, theramp 56 is located between thebrushes 50, but other orientations are permissible. - The
ramp 26 has aleading edge 50 separated from the floor surface by asmall gap 60. Theramp 56 inclines at a predetermined angle from the leadingedge 58 to a trailingedge 62, as shown inFIG. 3 . - A
vacuum motor 64 is mounted on thedeck 14. Thevacuum motor 64 may be such as an electric motor, depicted inFIGS. 1 , 2 and 6, powered by the battery located on thescrubber 12. Thevacuum motor 64 may be connected to avacuum filter 66 for filtering out dirt and debris from a vacuum stream, which is discussed below. - A
first tube 68 may connect a suction side of themotor 64 with thefilter 66 so as to draw air through the filter. Asecond tube 70 may be connected from the filter to acavity 72 defined by theramp 56. More particularly, thecavity 72 is defined by theramp 56 and twoside portions 74 extending downwardly from theramp 56. Agap 76, similar to thegap 60 between theleading edge 58 of theramp 56 and the floor, is provided between theside portions 74 and the floor. - The
second tube 70 draws air, which includes dirt and debris, from thecavity 72 to thefilter 66 where it collects and/or falls into adebris box 78. Thebristles 54 assist in collecting and directing debris to thecavity 72. - The trailing
edge 62 of theramp 56 is located directly adjacent thedebris box 78. More particularly, thedebris box 78 is located directly behind the trailingedge 62 of theramp 56. - The

An upper,outer corner aperture 140 is provided in thefirst side member 94. Thisaperture 140 is also aligned with thegroove 122 in thefirst track 114. Similar apertures are provided in thesecond side member 96. - The
body portion 134 of thepin 132 extends through thepin aperture 130 in thearm 124, through thetrack groove 122 where it is designed to be selectively located in the lower,inner corner aperture 138 to secure thedeck 14 and thedebris box housing 80 together. A biasing member, such as acoil spring 142, may be located about thepin body 134 so that thepin body 134 is biased inwardly into the lower,inner corner aperture 138. - The
head portion 136 of thepin 132 can be grasped and thehead portion 136 and thebody portion 134 of thepin 132 can be withdrawn from the lower,inner corner aperture 138. Thepin body 134 is now able to slide along thegroove 122 of thetrack groove 122 causes thepin 132, and thus thepin arm 124, to move in an upward motion. This motion results in thedeck 14 being raised. - The
deck 14 may be locked into a raised position by permitting thepin body 134 to extend through theaperture 130 in thepin arm 124, through thegroove 122 and into the upper,outer corner aperture 140. As shown inFIGS. 2 and 3 , theramp 56 and thedebris box 78 and itshousing 80 remain on the floor and are not elevated with thedeck 14. - The present invention also permits the
deck 14, theramp 56, thedebris box 78 and thehousing 80 to be elevated simultaneously with each other, as depicted inFIG. 2 . In this embodiment, thepin 132 is extended through thepin arm 124, through thegroove 122 and into the lower,inner corner aperture 138. Thepin 132 locks into the lower,inner corner aperture 138 and connects thedeck 14 with theramp 56,debris box 78 anddebris box housing 80 together. -
FIGS. 7-8 depict yet another embodiment of the present invention. The embodiment depicted inFIGS. 7-8 has many of the features discussed above, thus identical reference numbers will be used for the same features where discussion is required; where no additional discussion is required for the description ofFIGS. 7-8 , it can be appreciated that the two designs have the same features. Different features are provided with new reference numbers. - At least one
pin arm 144 extends downwardly, substantially perpendicularly, from thelower side 52 of thedeck 14. Afirst end 146 of thepin arm 144 is connected, such as welding and/or mechanical fasteners or the like, to thedeck 14. Preferably, thefirst end 146 of thepin arm 144 is in a fixed, non-moving relationship with thedeck 14. - Preferably, two pin arms (only one shown) extend down from the
deck 14. In a preferred embodiment, the pin arms both extend along the first andsecond side members - The
pin arm 144 has asecond end 148, opposite thefirst end 146. In the preferred embodiment, two apertures are located through thesecond end 148 of thepin arm 144. The apertures may be vertically aligned with one another on thearm 144. - A
first pin 150 is located through one of the apertures. In the figures, thefirst pin 150 is located through theupper aperture 152, but it may be located through either one. Thepin 150 extends through theupper aperture 152 where it engages thefirst side member 94. - The
first pin 150 may selectively engage thefirst side member 94 in a number of ways, but in each it is preferred that thepin 150 selectively secure thepin arm 144 and theside member 94 together. By way of example only, thepin 150 may extend into an aperture, housing or recess within or on theside member 94. Preferably, as shown inFIG. 8 , anaperture 154 is used. - Regardless of the manner in which the
pin 150 engages theside member 94, it is preferred that when thepin 150 engages theside member 94 that it locks the two together. More particularly, it is preferred that when the two are engaged, it prevents thepin arm 144 from pivoting with respect to theside member 94, and/or with respect to theramp 56, thedebris box 78 or thedebris box housing 80. - In the depicted embodiment, a
lower aperture 156 is located below theupper aperture 152 in thepin arm 144. Asecond pin 158 is located through thelower aperture 156. Thesecond pin 158 connects with thefirst side member 94 to permit selective pivotal movement of thepin arm 144 with respect to theside member 94 and/or withrespect 56 to the ramp, thedebris box 78 or thedebris housing 80. -
FIG. 7 depicts a brush andvacuum assembly 160 in a lowered position, where thedebris box 78 is located substantially parallel to the floor. The lowered position is the position used for floor cleaning. - The
first pin 150 is engaged with theaperture 154 in theside member 94 to maintain thedebris box 78 substantially parallel to the floor. It can be appreciated that thedebris box 78 can be easily accessed from aside 162 of theassembly 160, as thedebris box 78 is oriented substantially perpendicular to theramp 56. In other words, thedebris box 78 opens parallel with thehinge axis 26. -
FIG. 8 depicts the brush andvacuum assembly 160 in a raised position. The raised position might be used for maintenance or repair of theassembly 160. For example, the raised position may be helpful in changing or repairing thebrushes 50. - The raised position can be achieved by pulling the
first pin 150 from theaperture 154 in theside member 94. Preferably, thefirst pin 150 has a stop (not shown) that prevents it from being entirely withdrawn from theaperture 154. Once thefirst pin 150 is removed from theaperture 154, theside member 94, and the components connected to it, such as thedebris box housing 80, thedebris box 78 and theramp 56, are free to pivot about thesecond pin 158. - When the actuator is engaged, it draws the
deck 14 upwardly and backward, via thehinge 20, toward thefloor scrubber 12. At a first predetermined point, thepin arm 144 pivots about thesecond pin 158 on theside member 94. At a second predetermined point, thepin arm 144 lifts theside member 94 and the components associated with it, off the floor. Those components may include thedebris box 78, thedebris box housing 80 and at least a portion of theramp 56. This causes thedebris box 78 to assume a downward angle. - In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiments. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
