Adapter plate for a rotary floor scrubbing machine
View Patent ↗An apparatus is provided for the attachment of brushes to the drive system of rotary floor scrubbing machines. In one embodiment, the apparatus provides for a scrubbing plate assembly suitable for attachment to the drive system of a rotary floor scrubbing machine. The scrubbing plate assembly has a scrubbing plate and an adapter plate. When the adapter plate is aligned and in contact with a scrubbing plate, the adapter plate locks to the scrubbing plate by axial movement of said adapter plate relative to said scrubbing plate.
1. A scrubbing plate assembly for use on a rotary floor scrubbing machine, said scrubbing plate comprising:
a scrubbing plate having:
a mounting side;
a scrubbing side configured for having at least one scrubbing element positioned thereon; and
a central edge defining a central aperture; and
an adapter plate having:
a first side configured to attach to a drive system of said rotary floor scrubbing machine; and
a second side configured to attach to said scrubbing plate by a latching system, which locks under axial movement of said adapter plate relative to said scrubbing plate when said second side of said adapter plate is aligned and in contact with said mounting side of said scrubbing plate, wherein said latching system comprises:
a plurality of splines extending radially out from said adapter plate;
a plurality of grooves along said central edge of said scrubbing plate wherein said grooves are configured to receive said splines to prevent rotational movement of said adapter plate relative to said scrubbing plate; and
wherein said first portion of said splines has a compressing clip having a shoulder and a first portion of said grooves has a shoulder such that, when said adapter plate is attached to said scrubbing plate, said first portion of said splines and said first portion of said grooves mate so that said shoulders lock said adapter plate and scrubbing plate from relative axial movement.
2. The scrubbing plate assembly of claim 1 , wherein said adapter plate has a central aperture configured to mate with a key-type drive system.
3. The scrubbing plate assembly of claim 1 , wherein said adapter plate has radial ears configured to receive lugs for a lug-type drive system.
4. The scrubbing plate assembly of claim 1 , wherein said compression clip can be radially compressed so as to allow attachment and detachment of said adapter plate from said scrubbing plate.
