Abstract
A grouting pan assembly includes a reinforcement ring. In another aspect, a grouting pan includes a substantially planar bottom surface and a curved sidewall surrounding the bottom surface. In a further embodiment, a grouting pan assembly includes a grouting pan having a post or mechanical fastener extending from a backside thereof for attachment to a reinforcing ring or layer.
Claims35
A grouting pan assembly comprising:
- (a) a rotatable pad including a top surface, a floor-facing bottom surface and a peripheral surface;
- (b) a reinforcement layer attached to the bottom surface of the pad, the reinforcement layer being a flexible material;
- and
- (c) grouting pans attached to a floor-facing surface of the reinforcement layer.

A grouting pan assembly comprising:
- (a) a flexible pad;
- (b) a metallic reinforcement ring attached to the pad;
- (c) metallic grouting pans attached to the ring;
- (d) an electrically powered machine adapted to rotate the grouting pans to push grout into voids in a concrete, stone or terrazzo floor;
- and
- (e) the ring being adapted to torsionally flex for allowing all of the grouting pans to contact against the floor even when uneven floor conditions are encountered.
3 more elements
An apparatus comprising:
- (a) a rotatable flexible pad including a top surface, a floor-facing bottom surface and a circular peripheral surface;
- (b) a reinforcement layer, with a circular periphery, attached to the bottom surface of the pad, the reinforcement layer including multiple apertures;
- and
- (c) floor-contacting grouting pans each comprising at least one post projecting from a backside thereof, each of the posts extending through an associated one of the apertures in the reinforcement layer, each of the grouting pans including a circular periphery.
1 more element
A grouting pan assembly comprising:
- (a) a flexible and rotatable pad including a floor-facing surface and a circular peripheral surface;
- (b) a reinforcement layer attached to the floor-facing surface of the pad, the reinforcement layer being stiffer than the pad but being flexible, the reinforcement layer being thinner than the pad, and the reinforcement layer including a central hole through which a portion of the pad is exposed;
- and
- (c) metallic grouting pans attached to a floor-facing side of the reinforcement layer, each of the grouting pans including a circular periphery.
