Spreading apparatus for flowable materials and spreader pad therefor
A spreading apparatus is provided for spreading flowable materials such as adhesives and/or sealants on a surface such as a floor and/or a wall. The apparatus has a pad retainer for retaining a removable spreader pad and a reservoir chamber for flowable material pivotally attached to the pad retainer to permit pivoting of the reservoir chamber frontwards and backwards. The spreader pad comprises an elongated resilient foam member sufficiently thick to fit within and frictionally engage the pad retainer, and sufficiently high to extend below the pad retainer so that the spreader pad rather than the pad retainer contacts the surface when the spreader pad is retained by the pad retainer.
1. A pad for an apparatus with a pad retaining means, for spreading a flowable material onto a surface, the spreader pad comprising:
an elongated resilient foam member sufficiently thick to fit within and frictionally engage the pad retaining means, and sufficiently high to extend below the pad retaining means so that the spreader pad rather than the pad retaining means contacts the surface when the spreader pad is retained by the pad retaining means, and
a serrated spreader blade mounted at a first bottom edge of the elongated resilient foam member.
2. The pad of claim 1 wherein the foam member has an inner part sufficiently thick to fit within and frictionally engage inside surfaces of two walls of a tight tolerance channel of the pad retaining means, and has an outer part that covers an outside surface of one or both of the channel walls, and one or more grooves between the inner and outer parts within which one or both of the channel walls may fit.
3. The pad of claim 2 , wherein the foam member comprises two grooves, one for each channel wall.
4. The pad of claim 3 , wherein the foam member is U-shaped.
5. The pad of claim 4 , wherein the foam member has two arms extending at right angles from respective ends of a cross-member.
6. The pad of claim 1 , wherein the serrated spreader blade comprises one or more slits to impart greater flexibility thereto.
7. The pad of claim 1 , wherein the serrated spreader blade is engaged within one or more grooves in the foam member.
8. The pad of claim 1 , wherein the foam member is U-shaped having two arms extending at right angles from respective ends of a cross-member, and the serrated spreader blade is mounted at a first bottom edge of the cross-member.
9. The pad of claim 1 , wherein the elongated resilient foam member has a beveled bottom.
10. The pad of claim 9 , wherein the beveled bottom has an outside edge and an inside edge, the outside edge higher off the surface than the inside edge.
11. A pad for an apparatus with a pad retaining means, for spreading a flowable material onto a surface, the spreader pad comprising:
an elongated resilient foam member sufficiently thick to fit within and frictionally engage the pad retaining means, and sufficiently high to extend below the pad retaining means so that the spreader pad rather than the pad retaining means contacts the surface when the spreader pad is retained by the pad retaining means,
wherein the elongated resilient foam member is U-shaped with two arms extending at right angles from respective ends of a cross-member that has a beveled bottom, the beveled bottom having an outside edge and an inside edge, with the outside edge higher off the surface than the inside edge.
12. A pad for an apparatus with a pad retaining means, for spreading a flowable material onto a surface, the spreader pad comprising:
a U-shaped elongated resilient foam member, having two arms extending at right angles from respective ends of a cross member, the foam member being sufficiently thick to fit within and frictionally engage the pad retaining means with the arms and cross member fitting within and frictionally engaging a tight tolerance channel on the pad retaining means, and sufficiently high to extend below the pad retaining means so that the spreader pad rather than the pad retaining means contacts the surface when the spreader pad is retained by the pad retaining means, the cross-member having a beveled bottom with an outside edge and an inside edge, the outside edge being higher off the surface than the inside edge; and cross-member having a serrated spreader blade mounted thereon; and
the serrated spreader blade mounted on the cross member at the inside edge of the beveled bottom, the spreader blade having one or more slits therein to impart greater flexibility thereto.
