Abstract
Abstract An improved rotatable flagpole arrangement for supporting a flag or banner includes an elongate pole with structure thereon for mounting a flag or banner, a lower stop surface attached to the pole and a novel bearing arrangement between the stop surface and a support surface which utilizes a pair of embossed washers. The pole may be formed of a flexible material such as PVC so that it curves away from the wind as it rotates relative to the support socket, which creates a novel, dynamic visual effect.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
198 words
A rotatable flagpole arrangement of the type which is adapted to be supported in a vertically extending pipe shaped socket which has an upper surface, comprising: an elongate pole; means on said pole which is adapted for retaining a flag or like banner; means on said pole for defining a stop surface, said stop surface extending radially with respect to said pole and facing in a direction away from said retaining means; a first bearing washer having a maximum radial dimension and a maximum axial dimension, said maximum radial dimension being greater than said maximum axial dimension, a central opening for receiving said pole, a top surface which contacts said stop surface, and a bottom surface; and a second bearing washer having a maximum radial dimension and a maximum axial dimension, said maximum radial dimension being greater than said maximum axial dimension, a central opening for receiving said pole, a top surface which contacts said bottom surface of said first bearing washer and a bottom surface which is adapted to be supported by the upper surface of the pipe shaped socket, whereby an inexpensive rotatable flagpole arrangement is provided which is responsive to the direction of a wind.
Claim 2
Dependent Claim
198 words
A rotatable flagpole arrangement of the type which is adapted to be supported in a vertically extending pipe shaped socket which has an upper surface, comprising: an elongate pole; means on said pole which is adapted for retaining a flag or like banner; means on said pole for defining a stop surface, said stop surface extending radially with respect to said pole and facing in a direction away from said retaining means; a first bearing washer having a maximum radial dimension and a maximum axial dimension, said maximum radial dimension being greater than said maximum axial dimension, a central opening for receiving said pole, a top surface which contacts said stop surface, and a bottom surface; and a second bearing washer having a maximum radial dimension and a maximum axial dimension, said maximum radial dimension being greater than said maximum axial dimension, a central opening for receiving said pole, a top surface which contacts said bottom surface of said first bearing washer and a bottom surface which is adapted to be supported by the upper surface of the pipe shaped socket, whereby an inexpensive rotatable flagpole arrangement is provided which is responsive to the direction of a wind.
Claim 3
Dependent Claim
46 words
A flagpole arrangement according to claim 1, wherein said retaining means comprises a plurality of radially extending holes defined in said pole, a pair of eyelet bolts inserted into two of said holes, and means for securing each of said eyelet bolts into its respective hole.
Claim 4
Dependent Claim
58 words
A flagpole arrangement according to claim 1, wherein said stop surface defining means comprises a radially extending hole defined in said pole, a bolt extending through said hole and a nut for securing said bolt onto the pole, and said stop surface comprises one face on a head portion of said bolt, and one face on said nut.
Claim 5
Dependent Claim
35 words
A flagpole arrangement according to claim 1, further comprising cylindrical metallic means within a portion of said pole proximate said first and second bearing washers for reinforcing said pole against stress induced breaking and binding.
Claim 6
Dependent Claim
24 words
A flagpole arrangement according to claim 1, wherein said pole is formed of a material which is sufficiently flexible to bend with the wind.
Claim 7
Dependent Claim
12 words
A flagpole arrangement according to claim 5, wherein said material is PVC.
Claim 8
Dependent Claim
33 words
A flagpole arrangement according to claim 1, wherein said pole comprises an upper section and a lower section, said upper section having an outwardly flanged socket into which said lower section is received.
Claim 9
Dependent Claim
20 words
A flagpole arrangement according to claim 7, wherein said stop surface comprises a bottom surface of said outwardly flanged socket.
Claim 10
Dependent Claim
63 words
A flagpole arrangement according to claim 1, wherein at least one of said bottom surface of said first bearing washer and said top surface of said second bearing washer comprises embossed inner section means for reducing the amount of bearing surface which contacts the other of said sections, whereby bearing friction between said first bearing washer and said second bearing washer is reduced.
Claim 11
Dependent Claim
32 words
A flagpole arrangement according to claim 9, wherein both said bottom surface of said first bearing washer and said top surface of said second bearing washer comprise said embossed inner section means.
Claim 12
Dependent Claim
28 words
A flagpole arrangement according to claim 1, wherein said both comprises a first length; a second length and means for joining said first length to said second length.
Claim 13
Dependent Claim
45 words
A flagpole arrangement according to claim 11, wherein said joining means comprises a metallic splicing nippling which fits inside each of said first and second lengths; means for securing said first length to said nipple; and means for securing said second length to said nipple.
