Abstract
Abstract A lamp connected to a support with a flexible arm enclosing an electrical cable. Separate swivel mounts connected to opposite ends of the arm movably attach the arm to the support and to a lampshade. Each swivel mount has a stationary member with a fixed stop and a pair of relatively rotatable members mounted on the stationary member to permit approximately 600* of rotation of the flexible arm relative to the support and approximately 600* of rotation of the lampshade relative to the arm.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
147 words
A swivel mount comprising: a stationary member having a cylindrical body and a fixed stop located radially outwardly from the body, a first annular member positioned about the cylindrical body to rotatably mount the annular member on the stationary member, a leg on the first member selectively engageable with opposite sides of the stop to limit rotation of the first member relative to the stationary member, a second member having a bottom wall rotatably mounted on the cylindrical body of the stationary member, said bottom wall having a projection engageable with only the leg whereby the second member can rotate more than 360* relative to the stationary member and a sidewall surrounding the cylindrical body, fixed stop, first annular member and leg and compression spring washers located on opposite sides of the first member to provide a friction drag for both the first member and second member.
Claim 2
Dependent Claim
147 words
A swivel mount comprising: a stationary member having a cylindrical body and a fixed stop located radially outwardly from the body, a first annular member positioned about the cylindrical body to rotatably mount the annular member on the stationary member, a leg on the first member selectively engageable with opposite sides of the stop to limit rotation of the first member relative to the stationary member, a second member having a bottom wall rotatably mounted on the cylindrical body of the stationary member, said bottom wall having a projection engageable with only the leg whereby the second member can rotate more than 360* relative to the stationary member and a sidewall surrounding the cylindrical body, fixed stop, first annular member and leg and compression spring washers located on opposite sides of the first member to provide a friction drag for both the first member and second member.
Claim 3
Dependent Claim
33 words
The swivel mount of claim 1 wherein the first member is a collar rotatably mounted on the stationary member, said collar having a leg selectively engageable with opposite sides of the fixed stop.
Claim 4
Dependent Claim
17 words
The swivel mount of claim 2 wherein the leg extends axially into circumferential alignment with the projection.
Claim 5
Dependent Claim
34 words
The swivel mount of claim 2 wherein the leg extends radially outwardly and axially adjacent the stationary member in circular alignment with the stop whereby the leg selectively engages opposite sides of the stop.
Claim 6
Dependent Claim
23 words
The swivel mount of claim 5 including a support attached to the cup-shaped member adapted to connect an article to the cup-shaped member.
Claim 7
Dependent Claim
14 words
The swivel mount of claim 1 wherein: the compression spring washers are friction means.
Claim 8
Dependent Claim
104 words
A swivel mount comprising: a stationary member having a fixed stop, a first member rotatably mounted on the stationary member, a leg on the first member engageable with the stop to limit rotation of the first member relative to the stationary member, a second member rotatably mounted on the stationary member having a projection engageable with only the leg whereby the second member can rotate more than 360* relaTive to the stationary member, said second member comprising a lampshade having a projection engageable with only the leg of the first member whereby the lampshade can rotate more than 360* relative to the stationary member.
Claim 9
Dependent Claim
104 words
A swivel mount comprising: a stationary member having a fixed stop, a first member rotatably mounted on the stationary member, a leg on the first member engageable with the stop to limit rotation of the first member relative to the stationary member, a second member rotatably mounted on the stationary member having a projection engageable with only the leg whereby the second member can rotate more than 360* relaTive to the stationary member, said second member comprising a lampshade having a projection engageable with only the leg of the first member whereby the lampshade can rotate more than 360* relative to the stationary member.
Claim 10
Dependent Claim
33 words
The swivel mount of claim 7 wherein the first member is a collar rotatably mounted on the stationary member, said collar having a leg selectively engageable with opposite sides of the fixed stop.
Claim 11
Dependent Claim
17 words
The swivel mount of claim 8 wherein the leg extends axially into circumferential alignment with the projection.
Claim 12
Dependent Claim
34 words
The swivel mount of claim 8 wherein the leg extends radially outwardly and axially adjacent the stationary member is circular alignment with the stop whereby the leg selectively engages opposite sides of the stop.
Claim 13
Dependent Claim
19 words
The swivel mount of claim 7 including: friction means between the lampshade and a portion of the stationary member.
Claim 14
Dependent Claim
21 words
The swivel mount of claim 7 wherein the stationary member has a longitudinal passage providing an opening through the swivel mount.
Claim 15
Dependent Claim
119 words
A swivel mount comprising: a stationary member having a fixed stop and a cylindrical body, a plurality of rotatable members rotatably positioned on and around the cylindrical body, each rotatable member being rotatable relative to the stationary member, said plurality of rotatable members having coacting means which cooperate with the fixed stop to limit the rotation of each of the rotatable members, the rotatable member most remote from the fixed stop rotatable one revolution less than the total number of rotatable members plus rotatable movement less than 360* and compression spring friction means located on opposite sides of the rotatable members between the most remote member and the stationary member to provide a friction drag for said rotatable members.
Claim 16
Dependent Claim
119 words
A swivel mount comprising: a stationary member having a fixed stop and a cylindrical body, a plurality of rotatable members rotatably positioned on and around the cylindrical body, each rotatable member being rotatable relative to the stationary member, said plurality of rotatable members having coacting means which cooperate with the fixed stop to limit the rotation of each of the rotatable members, the rotatable member most remote from the fixed stop rotatable one revolution less than the total number of rotatable members plus rotatable movement less than 360* and compression spring friction means located on opposite sides of the rotatable members between the most remote member and the stationary member to provide a friction drag for said rotatable members.
