DETAILED DISCUSSION OF THE PREFERRED EMBODIMENT

As seen in FIG. 1, the present invention is a floor polishing armature having an inside ring 20 and an outside ring 30 connected by spokes including a first spoke 21, a second spoke 22, a third spoke 23, and a fourth spoke 24. Spoke openings are formed on the spokes and formed between the inside ring and outside ring. The outside ring forms a hub. Spoke openings including a first spoke opening 25 formed on the first spoke 21, a second spoke opening 26 formed on the second spoke 22, a third spoke opening 27 formed on the third spoke 23, and a fourth spoke opening 28 formed on the fourth spoke 24.


The inside ring connects to a floor polishing machine. Optionally, the inside ring 20 has an inside ring inside step 29. The hub portion of the wheel shaped floor polishing armature is preferably formed as an arc portion 40 having an arc portion profile. The arc portion sections have arc openings including a first arc opening 41 formed between the first spoke 21 and the second spoke 22, a second arc opening 42 formed between the second spoke 22 and the third spoke 23, a third arc opening 43 formed between the third spoke 23 and the fourth spoke 24, and a fourth arc opening 44 formed between the fourth spoke 24 and the first spoke 21.


As seen in FIG. 2, the first spoke opening 25 extends through a first disc retainer 31, the second spoke opening 26 extends through a second disc retainer 32, the third spoke opening 27 extends through a third disc retainer 33, and the fourth spoke opening 28 extends through a fourth disc retainer 34. The spoke openings are large enough for manual digit extension through the spoke openings allowing a user to reach an article through the spoke opening. The inside ring inside step 29 can be a gradual step profile.


The first air intake opening 35 is formed between the first spoke in the second spoke, the second air intake opening 36 is formed between the second spoke and the third spoke, the third air intake opening 37 is formed between the third spoke and the fourth spoke, and the fourth air intake opening 38 is formed between the fourth spoke and the first spoke. Preferably, a spoke indent 39 is formed on an underside of each spoke.


The first arc opening 41 extends into a first arc retainer 45. The second arc opening 42 extends into a second arc retainer 46. The third arc opening 43 extends into a third arc retainer 47. The fourth arc opening 44 extends into a fourth arc retainer 48. The arc portion has an arc portion outside sidewall 49 that can be flexible or rigid to assist in receiving an arc-shaped floor polishing pad.


As seen in FIGS. 3-6, the side views and the front and rear views are congruent such that the floor polishing armature has multiple sided symmetry, such as the four sided symmetry seen in FIG. 7.


As seen in FIG. 8, the spoke openings extend through to the disc retainers. The disc retainers are formed as round hollows having disc protrusion retainers 50 which include a distal disc protrusion retainer 51 opposite a proximal disc protrusion retainer 52, and a first lateral disc protrusion retainer 53 opposite a second lateral disc protrusion retainer 54.


The first spoke opening 25, the second spoke opening 26, the third spoke opening 27, and the fourth spoke opening 28 all have their respective disc protrusion retainers. The spoke openings are between the distal disc protrusion retainer 51 and the proximal disc protrusion retainer 52. The spoke openings are also between the first lateral disc protrusion retainer 53 and the second lateral disc protrusion retainer 54.


Adjacent to the spoke indent 39, the proximal disc sidewall 55 has a proximal disc protrusion retainer 52. The distal disc protrusion retainer 51 is formed on the distal disc sidewall 56 portion of the arc portion outside sidewall 49. The first lateral disc protrusion retainer 53 is formed on the first arc disc sidewall 57. The second lateral disc protrusion retainer 54 is formed on the second arc disc sidewall 58.


The first arc opening 41 passes through to the first arc retainer 45. The first arc retainer 45 has arc protrusion retainers 60. The arc protrusion retainers 60 include a proximal arc protrusion retainer 61 formed on the proximal arc retainer sidewall 63 and a distal arc protrusion retainer 62 formed on the distal arc retainer sidewall 64.


The second arc opening 42, the third arc opening 43, and the fourth arc opening 44 have a similar configuration is the first arc opening 41. Although arc openings extend downwardly into the arc retainer hollows. The arc retainers are bounded by an arc portion outside sidewall 49 having a distal arc retainer sidewall 64 from which protrude of distal art protrusion retainers 62. The proximal arc protrusion retainer 61 is opposite the pair of distal arc protrusion retainers 62.


As seen in FIG. 9, the inside ring upper surface 71 of the inside ring 20 can engage a floor polishing machine. Additionally, the inside ring has an inside ring interior surface 72 that also can engage a floor polishing machine. The access openings such as the arc openings and the disc openings preferably have a sloped opening profile 73 for tactile identification. The disc retainer is formed as a disc retainer hollow 74.


As seen in FIG. 10, a driving shaft 70 can have a driving shaft protrusion 75 and optionally a driving shaft step 76. The floor polishing armature is preferably interference fit with the driving shaft 70 such that can be readily removed with downward pressure. The downward pressure required for removing an armature is less than the downward pressure required for removing an insert. Downward pressure required can be calibrated by tightness of dimensions of interference fit.


The inserts 80 can be for sanding, scraping, scrubbing, buffing, polishing or any other floor construction or preparation process. The first disc insert 81, the second disc insert 82, the third disc insert 83, and the fourth disc insert 84 connect to the disc retainer hollows 74 of the disc retainers. Similarly, the arc inserts including the first arc insert 85, the second arc insert 86, the third arc insert 87, and the fourth arc insert 88 connect to the arc retainer hollows of the arc retainers. The inserts 80 have a lower surface which is the insert engagement area 89 which applies a floor treatment to a floor below it.


The inserts can be popped out and interchanged without removing the floor polishing armature from the driving shaft 70. If a floor conditioning process requires a first step with a first type of insert, a second step with a second type of insert, and a third step with a third type of insert, then the present invention allows hot swapping of inserts without removing the armature. A user can raise the floor polishing armature on the floor polishing machine, then pop out each insert as required. The inserts can also be mixed such that the disc inserts process a first floor treatment step while the arc inserts process a second for treatment step. The airflow through the airflow openings and the thinwall construction of the floor polishing armature having many lower hollows provides thermal dissipation while retaining rigidity and presenting a smooth upper surface.
