Abstract
Abstract A device is disclosed for supporting artist''s accessories on the tripod of an easel or the like. The device comprises a pair of spaced parallel coplanar arms which are connected the accessory to project therefrom, and to be rotatable about the longitudinal axes thereof, and which have free-ended convolutions on the projected end portions thereof that are rotated into a bind fit with a pair of legs in the tripod when the arms are generally horizontally disposed adjacent the legs and the device is rested thereon.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
In combination, a body and means for supporting the body in outrigger fashion on a pair of spaced upwardly obliquely inclined standards, including a pair of spaced parallel coplanar arms which are connected to the body to project therefrom and to be rotatable about the longitudinal axes thereof, and which have flanges on the projected end portions thereof, that in turn have reentrantly bent collets connected thereto, the bights of which undergo twist over the length thereof and are disposed in inverted relationship to the body, so that the collets can be passed about the standards from the flanges and rotated into engagement with the standards, to achieve a bind fit with the standards, wherein the flanges are rested on the relatively upwardly facing sides of the standards and the collets are engaged with the reverse sides of the standards at points spaced relatively thereabove.
Claim 2
Dependent Claim
145 words
In combination, a body and means for supporting the body in outrigger fashion on a pair of spaced upwardly obliquely inclined standards, including a pair of spaced parallel coplanar arms which are connected to the body to project therefrom and to be rotatable about the longitudinal axes thereof, and which have flanges on the projected end portions thereof, that in turn have reentrantly bent collets connected thereto, the bights of which undergo twist over the length thereof and are disposed in inverted relationship to the body, so that the collets can be passed about the standards from the flanges and rotated into engagement with the standards, to achieve a bind fit with the standards, wherein the flanges are rested on the relatively upwardly facing sides of the standards and the collets are engaged with the reverse sides of the standards at points spaced relatively thereabove.
Claim 3
Dependent Claim
53 words
The combination according to claim 1, wherein collets have a generally twisted U-shaped configuration and are connected at one end to the flanges, and there are hooks on the opposIte ends of the collets for engaging the relatively upwardly facing sides of the standards at a level above the flanges and the collets.
Claim 4
Dependent Claim
21 words
The combination according to claim 2, wherein the collets and hooks follow a generally smoothly curving spiral course from the flanges.
Claim 5
Dependent Claim
27 words
The combination according to claim 3, wherein the arms have free-ended convolutions on the projected ends thereof which take the form of truncated sections of a helix.
Claim 6
Dependent Claim
143 words
In combination, a body, a pair of spaced upwardly obliquely inclined standards, and means supporting the body in outrigger fashion on the standards, including a pair of spaced, parallel coplanar, generally horizontally disposed arms which are connected to the body to project therefrom, and to be rotatable about the longitudinal axes thereof, and which have flanges on the projected end portions thereof, that in turn have reentrantly bent collets connected thereto, the bights of which undergo twist over the length thereof and and are disposed in inverted relationship to the body, the flanges resting on the relatively upwardly facing sides of the standards and the collets passing about the standards and engaging the relatively downwardly facing sides of the standards at points spaced relatively thereabove, to achieve a bind fit therewith by virtue of the moment generated about the flanges by the body.
Claim 7
Dependent Claim
143 words
In combination, a body, a pair of spaced upwardly obliquely inclined standards, and means supporting the body in outrigger fashion on the standards, including a pair of spaced, parallel coplanar, generally horizontally disposed arms which are connected to the body to project therefrom, and to be rotatable about the longitudinal axes thereof, and which have flanges on the projected end portions thereof, that in turn have reentrantly bent collets connected thereto, the bights of which undergo twist over the length thereof and and are disposed in inverted relationship to the body, the flanges resting on the relatively upwardly facing sides of the standards and the collets passing about the standards and engaging the relatively downwardly facing sides of the standards at points spaced relatively thereabove, to achieve a bind fit therewith by virtue of the moment generated about the flanges by the body.
Claim 8
Dependent Claim
27 words
The combination according to claim 5, wherein the arms have free-ended convolutions on the projecting ends thereof which take the form of truncated sections of a helix.
