places the curved portion 56 of the curved connection wire 44 into the curved channel 50 by deflecting the resilient protrusion 54 upwards to allow the curved portion 56 to slide into the curved channel 50 the resilient protrusion 54 is biased towards the interior of the end cap 40 and therefore locks down around the curved portion 56 of the curved connection wire 44 once it has been completely enclosed inside of the curved channel 50 again the position of the side frame 42 is at an angle to the plane p through the channel 48 this forms a stable base out of the side frame 42 for holding the dowel bars 36 steady while the concrete is being poured those skilled in the art will recognize that the side frame 42 can be positioned in a range of angles from the plane p depending on the orientation of the curved channel 50 and the end cap 40 fig3 a and 3b also illustrate that the end cap 40 has an open end 64 that is designed to receive the dowel bar 36 in addition fig3 a and 3b illustrate that a first wall 66 and a second wall 68 define the channel 48 those skilled in the art will recognize that channel 48 can be formed in different manners in different aspects of the dowel bar assembly fig4 illustrates that the end cap 40 has a central portion 70 that includes a first end 72 for covering the end portion 38 of the dowel bar 36 the open end 64 receives the dowel bar 36 and.
