Abstract

A cage spacer for spacing reinforcing rods or welded fabric a specified distance from mold walls for poring concrete during construction projects. The cage spacer comprises two intersection legs in a V shape. The legs each have a clip portion for engaging and capturing the rods or welded fabric such that the cage spacers are oriented this their apex in a plane parallel to the plane of the face of the rods and the face of a mold. The clips are oriented perpendicular to the plane of the face of the rods or welded fabric such that the clips are attached by applying a force perpendicular to the plane of the rods. A pointed apex on the top of the cage spacer reduced the footprint of the cage spacer on the wall of the mold for a stronger wall when the molded concrete is formed.

Claims (8)

1. A cage spacer comprising:

a pair of legs each leg having a first end and a second end, the legs integrally joined at the first ends to form a V shaped body having a linear apex at the conjunction of the legs,

a pointed roof extending along the linear apex, the pointed roof having an apex spaced from the linear apex and along the line formed by the linear apex for limiting a footprint of contact between the cage spacer and a mold wall,

a clip member integrally attached at the second end of the legs for attaching the cage spacer to cylindrical objects, the clip member having,

a C shaped receiving portion having a trough with a first C shaped end and a second C shaped end defining the length of the trough, the length of the trough aligned parallel to the linear apex for receiving the cylindrical objects, the C shaped receiving portion trough having a curved surface portion with a circular cross section perpendicular the trough length for engaging approximately half of the circumference of the cylindrical object to hold it securely in the clip,

a pair of parallel arms integral with the C shaped receiving portion and extending beyond the cylindrical object,

a radially extending arm at an acute angle from and integral with each parallel arm, extending toward the center of the C shaped receiving portion such that the radially extending arms are pushed aside to allow the cylindrical object into the C shaped receiving portion and then returning to their relaxed positions to hold the cylindrical object in place.

2. A cage spacer as in claim 1 wherein, the C shaped receiving portions have a shoulder for allowing the radially extending arm to be detented adjacent thereto when pushing the cylindrical objects into the C shaped receiving portion.
