Abstract

An apparatus for combining adjacent concrete slabs including a dowel, an end cap, and a side frame. The end cap has a hood defining a curved channel extending at least partially around a dowel receiving end. The side frame has at least one wire received in the curved channel. Also, an end cap having an integrally formed supporting portion including first and second wire supports for supporting substantially parallel side frame cross wires. Also, an end cap including first and second sleeves positioned along opposing tangents of the outer peripheral surface of the end cap for receiving differing portions of a side frame, and further including a resilient protrusion for receiving a further differing portion of the side frame.

Claims

1. An end cap for connecting a side frame having a first cross wire and a second cross wire to a dowel comprising:

a receiving portion defining an interior area for receiving an end of said dowel; and

a supporting portion integrally formed with said receiving portion for supporting said side frame, the supporting portion including a first wire support for supporting said first cross wire and a second wire support for supporting said second cross wire, wherein the first and second wire supports are arranged substantially parallel to each other.

2. The end cap of claim 1, wherein said receiving portion includes a first clasp and a second clasp, and wherein said first clasp snap fits to said second clasp around said end of said dowel.

3. The end cap of claim 2, wherein said first clasp and said second clasp are interconnected by a living hinge.

4. The end cap of claim 1, wherein said receiving portion includes a removable top portion that slides over said end of said dowel.

5. The end cap of claim 1, wherein said receiving portion includes protrusions extending inwardly from the periphery of said receiving portion adjacent said interior area for frictionally engaging said end of said dowel.

6. The end cap of claim 1, wherein said first and second wire supports include resilient opposed clamps for snap fitting said side frame to said end cap.

7. The end cap of claim 1, wherein said first wire support and said second wire support are channels defined in said supporting portion.

8. An end cap for connecting a dowel to a side frame comprising:

a tubular central portion including a first end and a second end, wherein at least one of said ends is an open end for receiving said dowel and said tubular central portion defines an outer peripheral surface;

a first sleeve coupled to said central portion and positioned along a first tangent of said outer peripheral surface of said tubular central portion for receiving a portion of the side frame;

a second sleeve coupled to said central portion and positioned along a second tangent of said outer peripheral surface of said tubular central portion for receiving a different portion of the side frame, wherein said second tangent is on an opposite side of said outer peripheral surface of said tubular central portion from said first tangent; and

a resilient protrusion coupled to said central portion for receiving a further differing portion of said side frame.

9. The end cap of claim 8 wherein said first sleeve and said second sleeve are integrally formed with said central portion.
