Abstract
A flag anti-wrapping device for reducing friction and side loading, which are common causes of flag wrapping. The flag anti-wrapping device includes an inner race, an outer race, a plurality of roller bearings, and a cap. Roller bearings are placed in an annular cavity, which is defined by the outer race having an inner circumference with a diameter larger than an outer diameter of the inner race. Thus, a flag may rotate about a flagpole with reduced friction and side-loading. Thereby, eliminating side load binding and reducing wrapping of the flag about the flagpole.
Claims7
A flag anti-wrapping device, comprising:
- an inner race defining an inner diameter and an outer diameter, the inner diameter configured to receive a flagpole;
- an annular outer race adapted to be received on the inner race, the outer race defining an inner circumference having a diameter larger than the outer diameter of the inner race, so as to define an annular cavity between the inner race and outer race, wherein the outer race has means for attaching the device to a flag;
- a plurality of roller bearings residing in the annular cavity;
- and
- a cap attached to the inner race to hold the outer race and inner race together.
