Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A suspension device for holding a platelike object which comprises a sleeve member, a pair of elongated clamp members disposed to receive and grip the object along an edge portion thereof, said clamp members being telescopically received in said sleeve member for longitudinal adjustment to accommodate the length of said object edge portion, said sleeve member having a longitudinally extending slot accommodating the extension therethrough of said object edge portion into said clamp members, said sleeve member being disposed for contact with the clamp members along at least two sets of opposing outside surfaces of each clamp member to maintain said clamp members in longitudinal alignment, said clamp members each having a longitudinally extending keyway and at least one hanger member received in said keyway and retained thereby, said hanger member being longitudinally adjustable in the keyway, said clamp members each having a pair of longitudinally extending webs which are positioned for mutual contact and can be spread apart to receive and engage between them the edge portion of the object to grip and thereby support same.
Claim 2
Dependent Claim
177 words
A suspension device for holding a platelike object which comprises a sleeve member, a pair of elongated clamp members disposed to receive and grip the object along an edge portion thereof, said clamp members being telescopically received in said sleeve member for longitudinal adjustment to accommodate the length of said object edge portion, said sleeve member having a longitudinally extending slot accommodating the extension therethrough of said object edge portion into said clamp members, said sleeve member being disposed for contact with the clamp members along at least two sets of opposing outside surfaces of each clamp member to maintain said clamp members in longitudinal alignment, said clamp members each having a longitudinally extending keyway and at least one hanger member received in said keyway and retained thereby, said hanger member being longitudinally adjustable in the keyway, said clamp members each having a pair of longitudinally extending webs which are positioned for mutual contact and can be spread apart to receive and engage between them the edge portion of the object to grip and thereby support same.
Claim 3
Dependent Claim
126 words
A suspension device according to claim 1 including a first sleeve member, a first pair of elongated clamp members, a second sleeve member, and a second pair of elongated clamp members, said first pair of clamp members being disposed to grip the object along a first edge portion thereof, said first sleeve member being disposed to telescopically receive said first pair of clamp members for adjustment thereof to the length of said first edge portion, said second pair of clamp members being disposed to grip the object along a second edge portion thereof oppositely spaced from said first edge portion, said second sleeve member being disposed to telescopically receive said second pair of clamp members for adjustment thereof to the length of said second edge portion.
Claim 4
Dependent Claim
42 words
A suspension device according to claim 2 including a third pair of clamp members each disposed to engage another corresponding edge portion of said object, and connected to corresponding first and second pair clamp members to define a frame encompassing the object.
Claim 5
Dependent Claim
30 words
A suspension device according to claim 1 wherein said clamp members each have a pair of spaced-apart side walls and at least one transversely extending web connecting said side walls.
Claim 6
Dependent Claim
34 words
A suspension device according to claim 1 wherein said clamp members each have longitudinally extending surfaces that define a pair of parallel keyways disposed to receive and engage corresponding surfaces of a hanger element.
