Abstract

A power screed sled apparatus is provided including a power screed including an elongated frame with a pair of ends. Also included is a pair of skis each coupled to an associated end of the frame of the power screed for transporting the same.

Claims

1. A power screed sled apparatus comprising, in combination:

a power screed including an elongated frame with a pair of ends;

a pair of skis each including a planar plate with a periphery defined by a horizontally oriented linear top edge, a front edge with a vertically oriented linear upper portion and a linear lower portion extending downwardly and rearwardly from the upper portion, a rear edge including a linear upper portion extending downwardly and rearwardly from the top edge and a vertically oriented linear lower portion, and a horizontally oriented linear bottom edge with a length equal to that of the top edge, each of the skis further including a planar rectangular lip integrally coupled to the bottom edge and extending outwardly therefrom in perpendicular relationship therewith, a first oval cut out formed therein adjacent to the top edge and the upper portion of the front edge wherein the first oval cut out is situated in parallel relationship with the top edge, and a second oval cut out formed therein adjacent to the upper portion of the rear edge and in parallel relationship therewith;

a pair of elevation assemblies each including a vertically oriented cylinder mounted to a side of the corresponding ski from which the lip extends, the cylinder having a threaded interior, each elevation assembly further including a cylindrical tube slidably situated over the cylinder, a threaded post rotatably coupled within the tube and engaged with the threaded interior of the cylinder for raising the tube upon the rotation of the threaded post, an S-shaped crank assembly rotatably mounted to a top of the tube and engaged with a top end of the threaded post by way of a pair of bevel gears for selectively rotating the threaded post; and

a mounting assembly including a pair of guide bolts mounted on the associated ski so as to flank the associated cylinder, a pair of parallel vertical slider bars each having a bottom with a vertical slot formed therein for slidably receiving an associated one of the guide bolts, and a planar adapter plate coupled between top ends of the vertical slider bars and a central extent of the tube of the elevation assembly, wherein the adapter plates of the mounting assemblies may be secured to the ends of the power screed for elevating the power screed by way of the elevation assembly.

2. A power screed sled apparatus comprising:

a power screed including an elongated frame with a pair of ends;

a pair of skis each coupled to an associated end of the frame of the power screed for transporting the power screed sled apparatus; and

a pair of elevation assemblies each including a vertically oriented cylinder mounted to a side of a corresponding one of the pair of skis, each cylinder having a threaded interior, each elevation assembly further including a cylindrical tube slidably situated over the cylinder, a threaded post rotatable coupled within the tube and engaged with the threaded interior of the cylinder for raising the tube upon the rotation of the threaded post, a crank assembly rotatably mounted to a top of the tube and engaged with a top end of the threaded post by way of a pair of bevel gears for selectively rotating the threaded post.

3. The power screed sled apparatus as set forth in claim 2 wherein the skis are plates which reside in vertical planes.

4. The power screed sled apparatus as set forth in claim 3 wherein an outwardly extending lip is formed on a bottom edge of each plate.

5. The power screed sled apparatus as set forth in claim 2 wherein at least one cut out is formed in each ski for carrying purposes.

6. The power screed sled apparatus as set forth in claim 2, further comprising:

a mounting assembly including a pair of guide bolts mounted on the associated ski so as to flank the associated cylinder, a pair of parallel vertical slider bars each having a bottom with a vertical slot formed therein for slidably receiving an associated one of the guide bolts, and a planar adapter plate coupled between top ends of the vertical slider bars and a central extent of the tube of the elevation assembly, wherein the adapter plates of the mounting assemblies may be secured to the ends of the power screed for elevating the power screed by way of the elevation assembly.

7. The power screed sled apparatus as set forth in claim 6 wherein the skis are plates which reside in vertical planes.

8. The power screed sled apparatus as set forth in claim 7 wherein an outwardly extending lip is formed on a bottom edge of each plate.

9. The power screed sled apparatus as set forth in claim 6 wherein at least one cut out is formed in each ski for carrying purposes.
