Abstract
Abstract A storage structure includes at least four posts which provide the vertical framework for a rack arrangement. The posts are interconnected in pairs to form end frames and have vertical rows of slots in opposite surfaces. Longitudinally extending channels are connected to the posts by hooks having lower camming edges. After the hooks are received in the slots in the posts, the channels move downward to tighten the connection. The channels are used in matching pairs, and upwardly extending tabs are formed in the lower flange of the outer channel whereas the upper flange is formed with pockets or slots. The inner channel includes downwardly extending tabs in its upper flange, which are received in the slots or pockets of the outer channel, and similar pockets or slots in its lower flange which receive the upwardly extending tabs.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
164 words
A beam for use in a rack framework to interconnect two vertical posts, which posts are provided with means in opposite surfaces thereof for engagement with said beam, said beam comprising first and second longitudinally extending channel members each having a vertical web and horizontal upper and lower flanges at least a portion of the lower flange of said first longitudinal member being bent upward to create upwardly extending tab means and the lower flange of said second longitudinal member being formed with means proportioned to receive said tab means, at least a portion of the upper flange of said second longitudinal member being bent downward to create downwardly extending tab means and the upper flange of said first longitudinal member being formed with means proportioned to receive said downwardly extending tab means, said longitudinal members being provided with connecting means near their ends to interengage with the engagement means on said posts and support said members with said flanges extending toward each other.
Claim 2
Dependent Claim
164 words
A beam for use in a rack framework to interconnect two vertical posts, which posts are provided with means in opposite surfaces thereof for engagement with said beam, said beam comprising first and second longitudinally extending channel members each having a vertical web and horizontal upper and lower flanges at least a portion of the lower flange of said first longitudinal member being bent upward to create upwardly extending tab means and the lower flange of said second longitudinal member being formed with means proportioned to receive said tab means, at least a portion of the upper flange of said second longitudinal member being bent downward to create downwardly extending tab means and the upper flange of said first longitudinal member being formed with means proportioned to receive said downwardly extending tab means, said longitudinal members being provided with connecting means near their ends to interengage with the engagement means on said posts and support said members with said flanges extending toward each other.
Claim 3
Dependent Claim
41 words
A beam in accordance with claim 1 wherein said tab means extends for a major distance along the length of said first longitudinal member and wherein said second longitudinal is formed with downwardly open pocket means for receiving said tab means.
Claim 4
Dependent Claim
46 words
A beam in accordance with claim 1 wherein said downwardly extending tab means extends for a major distance along the length of said second longitudinal member and wherein said first longitudinal member is formed with upwardly open pocket means for receiving said downwardly extending tab means.
Claim 5
Dependent Claim
20 words
A beam in accordance with claim 2 wherein said tab means extends for substantially the entire length of said longitudinal.
Claim 6
Dependent Claim
20 words
A beam in accordance with claim 2 wherein said pockets are formed so as to frictionally engage said tab means.
Claim 7
Dependent Claim
35 words
A beam in accordance with claim 1 wherein said upper flange of said first longitudinal member and said lower flange of said second longitudinal member contain slots which are proportioned to receive said tab means.
Claim 8
Dependent Claim
25 words
A beam in accordance with claim 1 wherein the posts are provided with apertures and said connecting means comprise lugs which fit into said apertures.
Claim 9
Dependent Claim
31 words
A beam in accordance with claim 7 wherein said aperture are vertical slots and wherein said lugs are hooks proportioned to fit over and engage the bottom edges of said apertures.
Claim 10
Dependent Claim
34 words
A beam in accordance with claim 8 wherein said hooks have lower camming edges which move said vertical web into tight contact with said post upon engagement with said bottom edge of said aperture.
Claim 11
Dependent Claim
30 words
A beam in accordance with claim 1 wherein the vertical webs of said second longitudinal members are punched to form supports for deck panels that extend transverse to said beam.
Claim 12
Dependent Claim
170 words
A storage structure which comprises four vertical posts, which posts are provided with slots in opposite surfaces thereof, means interconnecting said posts in pairs to form end frames, and a plurality of beams extending between and connecting posts of opposite end frames, each of said beams including first and second longitudinally extending channel members, said channel members each having a vertical web and horizontal upper and lower flanges and being disposed with said flanges extending toward each other, said channel members being provided near their ends with hook means proportioned to be received in said slot means in said posts, said hook means permitting downward movement of said channel members after said hook means is received in said slot means, the lower flanges of said first and second longitudinals and the upper flanges of said first and second longitudinals being respectively formed with interengaging means to join said channel members into a composite beam, which interengaging means becomes engaged as a result of said downward movement of said second longitudinal.
Claim 13
Dependent Claim
170 words
A storage structure which comprises four vertical posts, which posts are provided with slots in opposite surfaces thereof, means interconnecting said posts in pairs to form end frames, and a plurality of beams extending between and connecting posts of opposite end frames, each of said beams including first and second longitudinally extending channel members, said channel members each having a vertical web and horizontal upper and lower flanges and being disposed with said flanges extending toward each other, said channel members being provided near their ends with hook means proportioned to be received in said slot means in said posts, said hook means permitting downward movement of said channel members after said hook means is received in said slot means, the lower flanges of said first and second longitudinals and the upper flanges of said first and second longitudinals being respectively formed with interengaging means to join said channel members into a composite beam, which interengaging means becomes engaged as a result of said downward movement of said second longitudinal.
Claim 14
Dependent Claim
72 words
A storage structure in accordance with claim 11 wherein the lower flange of said first channel member terminates in an upwardly extending subflange along a major portion of the length thereof and the upper flange in an upwardly open pocket and wherein the lower flange of said second channel member terminates in a downwardly open pocket and the upper flange in a downward-extending subflange along a major portion of the length thereof.
Claim 15
Dependent Claim
51 words
A storage structure in accordance with claim 11 wherein the lower flange of said first channel member includes upwardly extending tab means and the upper flange includes slot means and wherein the lower flange of said second channel member includes slot means and the upper flange includes downwardly extending tab means.
