Abstract

A system for attaching a mounting wall of a screed extension to a screed assembly including a first mounting component configured to be engaged within a first receptacle provided on the mounting wall. The first mounting component includes a first fastening member. The system further includes a second mounting component configured to be received within a second receptacle provided on the mounting wall. The second mounting component includes a second fastening member to engage with the first mounting member on the mounting wall and a mounting catch to engage with a mating wall of the screed assembly.

First claim

What is claimed is:

1. A system for attaching a screed extension to a screed assembly, the screed extension including a mounting wall, the system comprising:
a first mounting component configured to be engaged within a first receptacle provided on the mounting wall, the first mounting component including a first fastening member; and
a second mounting component configured to be received within a second receptacle provided on the mounting wall, the second mounting component including:
a second fastening member to engage with the first fastening member of the first mounting component; and
a mounting catch configured to engage with a mating wall of the screed assembly.

2. The system of claim 1 , wherein the first mounting component is disposed longitudinally along the mounting wall and the second mounting component is disposed transversely to the first mounting component.

3. The system of claim 1 , wherein the first mounting component includes a bolt and a pair of washers to engage with the first receptacle on the mounting wall of the screed extension.

4. The system of claim 3 , wherein the first fastening member includes a threaded end to be engaged with the second fastening member on the second mounting component.

5. The system of claim 1 , wherein the second mounting component includes a cylindrical hook assembly defining a first curved side and a second curved side diametrically opposite to the first curved side and wherein the second fastening member includes a threaded receptacle provided on the first curved side and the mounting catch being provided on the second curved side.

6. The system of claim 1 further comprising a mounting plate adapted to be secured to the mounting wall, the mounting plate including a first engaging receptacle to engage with the second mounting component and at least one fastening receptacle configured to receive a fastener for fastening the system with the mounting wall of the screed extension.

7. The system of claim 6 , wherein the at least one fastening receptacle of the mounting plate is an elongated receptacle.

8. A screed extension for a screed assembly, the screed extension comprising:
a mounting wall for attachment to a mating wall of the screed assembly, the mounting wall including:
a first receptacle and a second receptacle; and

a screed extension attachment system coupled to the mounting wall for attaching the screed extension to the screed assembly, the screed extension attachment system including:
a first mounting component engaged with the first receptacle, the first mounting component including a first fastening member; and
a second mounting component received within the second receptacle, the second mounting component including:
a second fastening member engaged with the first fastening member of first mounting component; and
a mounting catch configured to engage with the mating wall of the screed assembly.

9. The screed extension of claim 8 , wherein the mounting wall extends along a longitudinal axis of the screed extension, the mounting wall defining a top end and a bottom end, and wherein the first receptacle is provided at the top end and extends transverse to the longitudinal axis and the second receptacle extends from the top end downwardly along the longitudinal axis.

10. The screed extension of claim 8 , wherein the first mounting component includes a bolt and a pair of washers engaged within the first receptacle on the mounting wall of the screed extension.

11. The screed extension of claim 8 , wherein the first fastening member includes a threaded end engaged within the second fastening member of the second mounting member.

12. The screed extension of claim 8 , wherein the second mounting component includes a cylindrical hook assembly defining a first curved side and a second curved side diametrically opposite to the first curved side and wherein the second fastening member includes a threaded receptacle provided on the first curved side and the mounting catch provided on the second curved side.

13. The screed extension of claim 8 , wherein the screed extension attachment system further includes a mounting plate secured to the mounting wall, the mounting plate including a first engaging receptacle engaged with the second mounting component and at least one fastening receptacle receiving a fastener for securing the screed extension attachment system with the mounting wall.

14. The screed extension of claim 13 , wherein the at least one fastening receptacle of the mounting plate is an elongated receptacle.

15. The screed extension of claim 13 , wherein the mounting wall includes at least one complementary fastening groove aligned with the at least one fastening receptacle of the mounting plate and receive the fastener to secure the screed extension attachment system with the mounting wall of the screed extension.

16. A screed assembly comprising:
a main screed defining a lateral extension axis and including a mating wall defining a first longitudinal axis, the mating wall including:
a first cavity extending along the first longitudinal axis and defining

a catch protrusion therein;
a screed extension attached to the main screed, the screed extension including:
a frame defining a second longitudinal axis parallel to the first longitudinal axis;
a mounting wall attached to the mating wall of the main screed, the mounting wall extending along the second longitudinal axis and defining a top end and a bottom end, the mounting wall including:
a first receptacle formed at the top end; and
a second receptacle extending longitudinally downward from the top end along the second longitudinal axis, the second receptacle being aligned with the first cavity on the mating wall of the main screed; and
a screed extension attachment system coupling the mounting wall of the screed extension with the side wall of the main screed, the screed extension attachment system including:
a first mounting component positioned longitudinally along the mounting wall and engaged with the first receptacle, the first mounting component including a threaded end; and
a second mounting component positioned transversely to the first mounting component and received within the second receptacle on the mounting wall, the second mounting component including:
 a first curved side and a second curved side diametrically opposite to the first curved side;
 a threaded receptacle formed on the first curved side and engaged with the threaded end of the first mounting component; and
 a mounting catch formed on the second curved side and engaged with the catch protrusion on the mating wall of the main screed.

17. The screed assembly of claim 16 , wherein the first receptacle on the mounting wall of the screed extension extends transverse to the second longitudinal axis and the second receptacle extends along the second longitudinal axis of the screed extension.

18. The screed assembly of claim 16 , wherein the first mounting component includes a threaded bolt and a pair of washers engaged within the first receptacle on the mounting wall of the screed extension.

19. The screed assembly of claim 16 , wherein the screed extension attachment system further includes a mounting plate secured to the mounting wall, the mounting plate including a first engaging receptacle engaged with the cylindrical hook assembly and at least one fastening receptacle receiving a fastener and securing the screed extension attachment system with the mounting wall of the screed extension.
