Flag anti-wrapping device
View Patent ↗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.
1. 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.
2. The flag anti-wrapping device of claim 1 , wherein a bottom of the inner race has a first radially extending circumferential lip and wherein a bottom of the cap has a second radially extending circumferential lip to retain the bearings in the races.
3. The flag anti-wrapping device of claim 2 , wherein the roller bearings have a proximal end closely spaced with respect to the second radially extending circumferential lip and a distal end closely spaced with respect to the first radially extending circumferential lip, whereby the roller bearings are held in place between the first lip and the second lip.
4. The flag anti-wrapping device of claim 1 , wherein the inner race has a first annulus extending from a top of the inner race and wherein the cap has a second annulus extending from a top of the cap, and wherein the first annulus and the second annulus have means for attaching to each other, whereby the device is unitary.
5. The flag anti-wrapping device of claim 4 , wherein the means for attaching include a first hole on the inner race and a second hole on the cap, whereby the first and second holes can be aligned to receive a fastener to hold the inner and outer race together.
6. The flag anti-wrapping device of claim 4 , wherein the means for attaching include a plurality of inner threads in the cap, and a plurality of outer threads in the inner race configured to receive the inner threads, whereby the inner threads and outer threads can be twisted to hold the inner and outer race together.
7. The flag anti-wrapping device of claim 4 , wherein the means for attaching include an adhesive.
