Abstract
Abstract A rotatable and retractable storage lug (50), especially suited for, but not limited to, nuclear reactor applications is claimed. The lug (50) is equipped with a rotatable and slidable weight-cylinder assembly (76 and 64) in coaxial relationship with a pivoted support beam (60). Furthermore, the weight-cylinder assembly (76 and 64) and support beam (60) are connected together by a lockable channel (70 and 70A), groove (68 and 68A) and pin (62 and 62A) arrangement. By rotating the cylinder (64), the support beam (60) will assume either a horizontal or working position or a vertical or stored position.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
89 words
A support device for stacking and storing articles comprising a pair of parallel support plates, a pair of opposed independent coplanar pins extending inwardly from the plates, support means disposed between the plates and pivotally suspended by the pins, the pins partially extending through the support means, a cylindrical member slidably and coaxially disposed within the support means, the member slidably and rotatably engaging the pins, a weight attached to the member, means for rotating the member and means for affixing the device to the article to be stored.
Claim 2
Dependent Claim
89 words
A support device for stacking and storing articles comprising a pair of parallel support plates, a pair of opposed independent coplanar pins extending inwardly from the plates, support means disposed between the plates and pivotally suspended by the pins, the pins partially extending through the support means, a cylindrical member slidably and coaxially disposed within the support means, the member slidably and rotatably engaging the pins, a weight attached to the member, means for rotating the member and means for affixing the device to the article to be stored.
Claim 3
Dependent Claim
47 words
The device according to claim 1 wherein the cylindrical member includes two opposed independent arcuate channels extending partially along the outer circumference of the member and transversely to the centerline of the member and two opposed independent longitudinal grooves partially extending along the length of the member.
Claim 4
Dependent Claim
19 words
The member according to claim 2 wherein one end of each groove is in perpendicular registry with a channel.
Claim 5
Dependent Claim
19 words
The device according to claim 1 including means for limiting the amount of movement experienced by the support means.
Claim 6
Dependent Claim
62 words
The device according to claim 1 wherein the pins support the support means at a predetermined distance away from the center of gravity of the support means so that as the member is repositioned, the center of gravity of the device will correspondingly shift thereby causing the support means to pivot about the pins as a result of the influence of gravity.
Claim 7
Dependent Claim
21 words
The device according to claim 1 wherein the means for rotating the member is in the shape of a closed ring.
Claim 8
Dependent Claim
21 words
The device according to claim 1 wherein the support means includes a square block with a circular cross-sectional passageway extending therethrough.
Claim 9
Dependent Claim
97 words
In combination with an indexing fixture including at least two apertures, a support device for storing the fixture above similarly sized articles, the device comprising a pair of parallel support plates, a pair of opposed independent coplanar pins extending inwardly from the plates, support means disposed between the plates and pivotally suspended by the pins, the pins partially extending through the support means, a cylindrical member slidably and coaxially disposed within the support means, the member slidably and rotatably engaging the pins, a weight attached to the member, and means for securing the device about each aperture.
Claim 10
Dependent Claim
97 words
In combination with an indexing fixture including at least two apertures, a support device for storing the fixture above similarly sized articles, the device comprising a pair of parallel support plates, a pair of opposed independent coplanar pins extending inwardly from the plates, support means disposed between the plates and pivotally suspended by the pins, the pins partially extending through the support means, a cylindrical member slidably and coaxially disposed within the support means, the member slidably and rotatably engaging the pins, a weight attached to the member, and means for securing the device about each aperture.
Claim 11
Dependent Claim
47 words
The device according to claim 8 wherein the cylindrical member includes two opposed independent arcuate channels extending partially along the outer circumference of the member and transversely to the centeline of the member and two opposed independent longitudinal grooves partially extending along the length of the member.
Claim 12
Dependent Claim
19 words
The member according to claim 9 wherein one end of each groove is in perpendicular registry with a channel.
Claim 13
Dependent Claim
19 words
The device according to claim 8 including means for limiting the amount of movement experienced by the support means.
Claim 14
Dependent Claim
62 words
The device according to claim 8 wherein the pins support the support means at a predetermined distance away from the center of gravity of the support means so that as the member is repositioned, the center of gravity of the device will correspondingly shift thereby causing the support means to pivot about the pins as a result of the influence of gravity.
Claim 15
Dependent Claim
21 words
The device according to claim 8 wherein the means for rotating the member is in the shape of a closed ring.
Claim 16
Dependent Claim
21 words
The device according to claim 8 wherein the support means includes a square block with a circular cross-sectional passageway extending therethrough.
