Abstract
The invention concerns a carrier plate holding an abrading element, for detachable mounting on a rotatably mounted abrading plate driven during use, for abrading stone or concrete floors, which carrier plate has sides which form an acute angle with each other. The sides have flanges which are formed for surrounding engagement with a shoulder arranged on the abrading plate so that the carrier plate can be fixed on the abrading plate with an engagement based on form and friction
Claims11
A carrier plate detachably mounted on a rotatably mounted abrading plate driven during use to abrade stone or concrete floors, the carrier plate comprising:
- a top surface having a first edge shorter than an opposing second edge;
- at least one abrading element affixed to the top surface;
- a first side arranged on a third edge of the top surface;
- a second side arranged on a fourth edge of the top surface, the fourth edge opposing the third edge;
- and
- two flanges, each flange arranged on a respective one of the third and fourth sides, to surround a should arranged on the abrading plate,
- wherein the shoulder has side edges that are undercut to correspond to the two flanges so that the carrier plate can be fixed on the abrading plate with an engagement based only on form and friction.
An abrading plate rotatably mounted and driven during use to abrade stone or concrete floors, the abrading plate having at least one carrier plate detachably mounted thereon, the carrier plate having at least one abrading element, the abrading plate comprising:
- at least one undercut shoulder, each undercut shoulder including a first side arranged to form an acute angle with respect to a second side, the acute angle being bisected by a line from the center of the abrading plate to the edge of the abrading plate, each undercut shoulder being provided to engage with flanges arranged on the carrier plate so that the carrier plate, by surrounding engagement, can be fixed on the abrading plate based on form and friction without fasteners.
An abrading device rotatably mounted and driven during use to abrade stone or concrete floors, comprising:
- a carrier plate to hold at least one abrading element for abrading stone or concrete floors, the carrier plate including,
- a top surface having a first edge shorter than an opposing second edge,
- at least one abrading element affixed to the top surface,
- a first side arranged on a third edge of the top surface,
- a second side arranged on a fourth edge of the top surface, the fourth edge opposing the third edge, and
- two flanges, each flange arranged on a respective one of the third and fourth sides, to surround a should arranged on the abrading plate;
- and
- an abrading plate having an undercut shoulder including two sides, one side forming an acute angle with respect to the other side, the acute angle being bisected by a line from a center of the abrading plate to an edge of the abrading plate,
- wherein the undercut shoulder is provided to engage the flanges of the carrier plate so that the carrier plate, by surrounding engagement, can be detachably mounted on the abrading plate with an engagement based only on form and friction.
A system for abrading stone or concrete floors comprising:
- a carrier plate to hold at least one abrading element for abrading the stone or concrete floors, the carrier plate including,
- a top surface having a first edge shorter than an opposing second edge,
- at least one abrading element affixed to the top surface,
- a first side arranged on a third edge of the top surface,
- a second side arranged on a fourth edge of the top surface, the fourth edge opposing the third edge, and
- two flanges, each flange arranged on a respective one of the third and fourth sides, to surround a should arranged on the abrading plate;
- an abrading plate having an undercut shoulder including two sides, one side forming an acute angle with respect to the other side, the acute angle being bisected by a line from a center of the abrading plate to an edge of the abrading plate, the undercut shoulder engaging the flanges of the carrier plate so that the carrier plate, by surrounding engagement, can be detachably mounted on the abrading plate with an engagement based only on form and friction;
- and
- a machine having the abrading plate mounted thereon, the machine including a motor to rotate the abrading plate to abrade the stone or concrete floor.
A method of abrading a stone or concrete floor, comprising:
- providing a carrier plate to hold at least one abrading element for abrading the stone or concrete floors, the carrier plate including,
- a top surface having a first edge shorter than an opposing second edge,
- at least one abrading element affixed to the top surface,
- a first side arranged on a third edge of the top surface,
- a second side arranged on a fourth edge of the top surface, the fourth edge opposing the third edge, and
- two flanges, each flange arranged on a respective one of the third and fourth sides, to surround a should arranged on the abrading plate;
- detachably mounting the carrier plate on an abrading plate having an undercut shoulder including two sides, one side forming an acute angle with respect to the other side, the acute angle being bisected by a line from a center of the abrading plate to an edge of the abrading plate, the undercut shoulder engaging the flanges of the carrier plate an engagement based only on form and friction;
- rotating the abrading plate with the carrier plate mounted thereon over the stone or concrete floor;
- and
- driving the abrading plate across the stone or concrete floor while rotating to abrade the stone or concrete floor.
